The data used for the LRWWMP was current as of December 31, 2007 and the LRWWMP was developed in 2008 and 2009 for approval in 2010. This plan will be used as a guide in maintaining and improving the sanitary sewer system over the next six years in order to provide the Renton Sewer Service Area with an effective, safe and reliable sewer system. While this plan is an update to the 1998 Long-Range Wastewater Management Plan adopted in 1999; it is a re- evaluation of the entire sanitary sewer system and a stand-alone document, not a supplement. A summary of this plan's findings and recommendations are presented in this chapter. The plan results from an evaluation of the existing sanitary sewer system and recommendations to resolve existing deficiencies and concerns, and to accommodate growth. The improvements identified in this plan are based on the requirements of the Washington State Department of Health, Washington State Department of Ecology, King County Comprehensive Plan, and City Comprehensive Plan. The City's Comprehensive Plan is the overall guidance for future growth within the City of Renton. This LRWWMP is an element of the City's Comprehensive Plan. The Renton sanitary sewer system is large, and because ofthe topography, complex in its operation. The condition of the current system, as well as the need for improvements, has been documented in this report. Due to the complexity of this system and the number of issues that must be addressed, this report is organized so that a reader may review a summary of it and its recommendations in this chapter without reading the'-background or detailed information that led to those results. The LRWWMP provides a recognized framework for making decisions about Renton's sanitary sewer service area, which includes properties both inside and outside the City limits. It is intended to aid decision-makers as well as users, including the Wastewater Utility, City Council members, the Mayor and staff, builders, developers, community groups, and other government agencies. The LRWWMP will be a useful tool in the following ways: • As a framework for improvements and operations that govern sanitary sewer system developments in the Renton Wastewater Utility service area. The LRWWMP provides a basis.for allocating improvements and costs to new sanitary sewer system users such as home and apartment builders, and commercial developers. It thus provides officials with partial direction for approving building permits and upgrading the system. Final 2010 1-1 • To provide a guideline for improving the existing system so that each customer receives adequate sanitary sewer service. It is intended that City officials be able to use these guidelines to maintain a high quality of service at a reasonable cost. • To provide a basis for accommodating changes that occur but that cannot be forecast in the LRWWMP. To this end, the LRWWMP lists policy issues and operational criteria that can be used to develop alternatives and directions for development, improvements, and operations. 1.2 SCOPE OF STUDY The scope of study includes the following: • Coordinate LRWWMP with adjacent utility systems and identify areas for potential service area boundary adjustments. • Document City policies regarding growth and service areas. • Estimate wastewater flow rates using land use designations. • Analyze the existing system to determine its deficiencies and needed improvements. • Prepare a Capital Improvement Program and estimate its construction costs. • Document, in summary form, the existing operations and maintenance program and recommend improvements and staff additions. • Analyze the recent financial performance of the sewer utility and develop a financial operating projection statement.

This system consists of approximately 191 miles of gravity sewer, 23 sewage lift stations and force mains, and approximately 5,107 manholes. Wastewater is discharged to King County facilities at 79 locations within the City Service Area from which it is conveyed to and treated by King County's South Treatment Reclamation Plant. The City of Renton Service Area is divided into six major wastewater collection basins: Black River, Downtown, East Cedar River, East Lake Washington, May Valley, and West Cedar River. For the most part, these major collection basins follow the natural drainage patterns of the Renton service area. For the purposes of monitoring and modeling the sanitary sewer system, the major collection basins are divided into one or more model basins. King County developed 11-model basin for the Renton service area as part of its Infiltration and Inflow Program. Each model basin is the area tributary to the downstream location where the City and King County used meters to collect flow data during the 2000/2001 and 2001/2002 flow monitoring seasons for King County's Infiltration and Inflow Program. This flow data was used for the creation and calibration of the City's hydraulic sewer model developed by Roth Hill and used in this LRWWMP. 1.5 POLICIES AND DESIGN CRITERIA Policies, design criteria, and standards used for planning and operating the sanitary sewer system are based on laws and policies that originate from several sources. All these policies and standards have the general purpose of providing an acceptable level of service to the sanitary sewer customers. Policies presented in this LRWWMP include the following: customer service policies, financial policies, facility policies, and organizational policies. Analysis and design criteria for the sanitary sewer system are based on standards presented in the Criteria for Sewage Works Design prepared by the Washington State Department of Ecology as well as standards set by King County Department of Natural Resources -Wastewater Treatment Division and the City of Renton. 1.6 PLANNING CONSIDERATIONS The City of Renton Wastewater Utility has a service area that encompasses a wide variety of residential, commercial, and industrial land uses over 13,484 acres. There are several adjacent utility systems surrounding the City's existing service area, which limit the expansion of the City's sewer system. The greatest potential for expansion of the City's Final 2010 1-4 pw:\\Documents\Client\WA\Renton\7963A00\Deliverables\Chapter 1\Chapt0l sanitary sewer system is within the May Valley, Skyway and East Renton areas that currently either do not have existing or adequate sanitary sewer facilities. Future sewer system requirements are based upon growth projections within the established sewer service area, derived from the Renton Traffic Analysis Zone (RTAZ) projections. In addition to the RTAZ projections, future planning data for areas outside the current City boundaries was based on Traffic Analysis Zone (TAZ) data obtained from the Puget Sound Regional Council (PSRC). Based on these sources the residential population within the service area is expected to grow from 44,504 in 2001 to 102,901 by the ultimate saturation year, which represents a growth of approximately 230 percent. The ultimate saturation year is anticipated to be after 2030. The commercial population is excepted to grow from 49,128 in 2001 to 103,357 at ultimate saturation representing a growth of 210 percent. Wastewater flow generation was modeled based on an assumed domestic generation of 100 gals/d-person while infiltration and inflow (I/I)'is modeled at 1,500 gallons per acre per day (gpad). Peak storms were assumed to increase the flow rate by a factor of 2 to 1. 1.7 KEY ISSUES This LRWWMP addresses the following key issues: • The need and timing of the replacement of older, deteriorating sanitary sewer facilities within large, neighborhood, size areas of the City. • The evaluation of Renton's facilities for system capacity, to address both system deficiencies and potential development within Renton's sewer service area. • The evaluation of sanitary sewer lift stations for removal, rehabilitation and replacement. • The City's I/I program in coordination with the overall King County program to evaluate option and needs for I/I reduction. • Review of industrial waste and grease discharges to the sewer system and the need for monitoring and coordination with the public to eliminate problems that potentially lead to sewer overflows. Some of these issues were also addressed during preparations of the 1992 and 1998 Long-Range Wastewater Management Plans. 1.8 SYSTEM ANALYSIS A hydraulic and a structural analysis were conducted to determine how well the existing system achieved current policies and technical, engineering standards. The LRWWMP Final 2010 1-5 pw:\\Documents\Client\WA\Renton\7963A00\De0erables\Chapter 1\Chapt01 identifies where the system failed to meet those objectives and recommends improvements to the existing system or construction of new facilities to achieve them. A hydraulic analysis was performed by a computer simulation of the existing system to determine its ability to convey wastewater at saturation flow rates. The Wastewater Utility's computer model was used to analyze the system and to size future facilities. This model was updated in 2006 using the MOUSE software program. The software platform was chosen to be consistent with the software platform used by King County regional infiltration and inflow study. The model was calibrated to the year 2001 and then expanded for the 2030 ultimate buildout condition. This computer model will continue to be used by the City as an analytical, planning and management tool. A structural analysis, which is a visual inspection of the existing system, was also conducted and was based on video, as well as actual, physical inspections. Based on the hydraulic model analysis, flow projections were developed for each mini-basin. Between 2001 and the ultimate buildout, peak flows increased by an average of 1.6 times for each mini-basin. However, seven of the 53 basins actually experienced a decrease in flow with the highest decrease for the ultimate year modeled at 45 percent of the 2001 flow. Additionally, the model projected that for a couple of the mini-basins, the flow increase would be considerably higher than average, with the largest modeled ultimate peak flow increase being 7.65 times greater than the 2001 condition. The analysis revealed deficiencies that cover a broad range of areas. The hydraulic deficiencies identified are inadequate slopes (inability to achieve carrying velocities), insufficient capacity to handle wastewater flow rates, pipes that are less than 8-inches in diameter and sections that have reverse slopes. Structural deficiencies identified are pipe sag, and root and grease problems. The Renton sewer system has these hydraulic and structural problems in varying degrees throughout the system. 1.9 SEPA AND APPROVAL PROCESS A SEPA Checklist has been prepared for this LRWWMP and is presented in Appendix C. It is anticipated that this proposed LRWWMP will not have a probable significant adverse impact on the environment and that an environmental impact statement (EIS) will not be required. However, many of the projects proposed herein will require SEPA checklists and an engineering determination will be made with each individual project. This LRWWMP includes review by adjacent utility systems. All comments are include in Appendix D. Final 2010 1-6 pw:\\Documents\Client\WA\Renton\7963A00\Deliverables\Chapter 1\Chapt01 1.10 CONCLUSIONS AND RECOMMENDATIONS In the development of this LRWWMP, the following conclusions were reached: 1. A substantial percentage of the system has reached or is reaching the end of its useful life and needs to be replaced. The projects of highest concern are: a. Several system wide projects including: miscellaneous sewer projects and emergency repairs, Earlington sanitary sewer replacements, Renton Central Business District sewer replacement, Renton Hill sanitary sewer replacement. b. Two projects in the West Cedar River Basin: Heather Downs/Maplewood interceptor improvement and the Falcon Ridge lift station rehabilitation. c. Several projects in the East Cedar River Basin including: the Central Plateau interceptor, East Cedar River collection sewers, Evendell lift station elimination, East Renton lift station elimination and the Highlands Estates lift station elimination. d. Several projects in the Lake Washington East Basin including: Stonegate/Summerwind flow diversion, the Duval interceptor, the Westview lift station replacement/rehabilitation, the Sierra Heights sewer system construction and the Lake Washington Beach lift station rehabilitation. e. Three projects in the Black River Basin including: the Thunder Hill interceptor replacement, the SW 34th street interceptor replacement and the Lind Avenue lift station rehabilitation. f. Several projects in the Downtown Basin including: Earlington lift station elimination, the Shattuck Ave S. interceptor downsizing, the Renton Center sewer extension, the Airport lift station rehabilitation and the North Earlington collection system. g. Two projects in the May Valley Basin including: the Misty Cove/Baxter lift station replacement, and the Denny's lift station rehabilitation. 2. Continue development of the gravity sewer system in order to allow the elimination of existing sewage lift stations. These lift stations are less reliable, require higher maintenance and operations costs and cause more adverse impacts to downstream facilities than do properly planned gravity sewer systems. 3. Rehabilitate or replace the sewage lift stations that are considered to be permanent sewage facilities. These improvements will reduce maintenance costs and increase system reliability. As the City rehabilitates or replaces regional stations, on-site emergency power generators should be installed. 4. The City needs to continue to update its hydraulic model to reflect the new adopted land use designations and concurrency standards, changes in development patterns, system changes, and as data becomes more current. The City should continue the model update by completing the inventory of the sewer system, verifying the as-built records and gathering data on those parts of the system that are not recorded. Final 2010 1-7 pw:\\Documents\Client\WA\Renton\7963A001Deliverables\Chapter 1\Chapt0l 5. The City should implement a flow monitoring program to meter flows in order to gather data to calibrate the sanitary sewer computer model. This will enable the model to be more closely calibrated in areas of concern. The City will continue to use the sewer model to develop a schedule of timing for capacity system improvement projects. As the County looks to implement 10-year cycle flow monitoring, the City should look at potential saving by partnering in the monitoring. 6. The City needs to establish a grease and industrial waste discharge program for the Wastewater Utility. Grease is the leading cause of sewer overflows in our system. Industrial waste poses a serious risk to our sewer maintenance personnel. 7. The City needs to evaluate capacity restraints, analyzing them from both the potential of increasing capacity and reducing I/I within the,basins that facilities serve. Where reduction in Ill is at a similar cost of upsizing facilities, serious consideration shall be given to the Ill alternative. 8. Where the City annexes an area that is currently unsewered by another municipality, the City should provide sewer service. Where annexation occurs and sewer service is provided by another municipality, the City should determine whether to purchase the facilities from the adjacent municipality, or to continue to allow the existing agency to provide service. Purchase of facilities should be based on the actual depreciated cost the municipality incurred from providing the facilities to obtain service. 9. The rate increases recommended in this LRWWMP should be considered an estimate to implement the City-funded portion of all the recommended improvements. Currently, new development pays a major portion of the remaining cost of recommended improvements. If funding from this source, such as the System Development Charge or Special Assessment District Charges, are not available, the City's share of these construction costs will most likely increase. It should also be recognized that this LRWWMP does not establish annual Capital Improvement Programs (CIPs) or sewer rates, but rather provides a roadmap and guideline for the operation of the system. Yearly CIPs and sewer rates are established as part of the budget process. The City should update the financial models in a manner consistent with the City's budget schedule, so that rates can be adopted to accurately reflect the current financial situation within the utility. These models were developed as part of the 2006/2007 Rate Study undertaken at the same time this LRWWMP is being updated (Comprehensive Rate Study, Water, Wastewater, and Surface Water Utilities, Financial Consulting Solutions Group, Inc., 2006/07). 10. This LRWWMP should be updated at intervals of no greater than six years in order to accommodate unforeseen changes in existing assumptions, conditions and land use designations, and for adjustingbudgets and sewer service rates. Final 2010 1-8 pw:\\Documents\Client\WA\Renton\7963A00\Deliverables\Chapter 1\Chapt01 Chapter 2 OVERVIEW OF EXISTING SEWER SYSTEM This chapter presents an overview of the existing sewer system as of January 1st, 2008. As such, this does not present information on more recent annexations to the system that occurred after January 1st, such as the Benson Hill annexation. A more extensive description and analysis of the system, along with recommended improvements, can be found in Chapter 5. 2.1 OVERVIEW OF EXISTING SYSTEM The City of Renton (City) is approximately 17.7 square miles with a population of over 60,290. Renton's sanitary sewer service area is approximately 21.68 square miles with about 3.91 square miles outside of the city limits. The City's collection system is municipally owned, operated and maintained and is managed by the City's Public Works Department (Public Works). The City maintains 23 sewage lift stations. In addition, there are approximately 15 privately owned and maintained sewage lift stations serving apartment complexes, commercial industrial properties or schools in the City's service area. Wastewater is discharged to King County facilities at 79 locations within the City, from which it is conveyed to and treated by King County's South Treatment Reclamation Plant. The City's system contains approximately 191 miles of sewer, 5,107 manholes, and over 16,024 customer connections. Figure 2.1 illustrates the existing sewer system. 2.2 SYSTEM HISTORY Sanitary sewer facilities were first constructed in the downtown area of the City in 1910. Prior to that it was common practice to dispose of wastewater on-site or to directly discharge it to the local estuaries. By 1940 the City's population had grown to 4,800; wastewater was collected and treated in a large septic system located adjacent to the Black River channel. During the 1940s, federal housing was constructed in the City to accommodate workers employed by defense industries. By 1956 the wastewater collection system served a population of 14,800 people within the City's service area. By that time wastewater was treated in a secondary treatment plant located near the current Renton High School Stadium. This treatment plant discharged treated wastewater to the Cedar River. In 1958 the Municipality of Metropolitan Seattle (METRO) was formed to solve the growing problem of pollution in Puget Sound, Lake Washington, and surrounding waters. METRO developed a regional plan for wastewater collection and treatment facilities in 1959 and assumed operating responsibilities for the regional interceptors and waste treatment systems in 1962, including Renton's secondary treatment plant.

As part of expansion in the 1980's, a new discharge was constructed to the Duwamish Water Way. This location is the current site of King County's South Treatment Reclamation Plant, which serves as one of the regional treatment facilities. The City of Renton sanitary sewers now discharge to these facilities. In 1993, the citizens of King County voted to combine the Metro and King County governments into a new regional government, Metropolitan King County. Metro's wastewater treatment, water quality and transit responsibilities became part of an interim Department of Metropolitan Services for 2 years while the new government created its new structure. In 1996, the wastewater treatment and water quality functions of the Department of Metropolitan Services were transferred to the new King County Department of Natural Resources. The responsibilities of the former Metro Council, which provided oversight of wastewater treatment service for the first 35 years, now lie with the new Metropolitan King County Council. In 1999, the King County Wastewater Treatment Division adopted its Regional Wastewater Services Plan that provides regional guidance on sanitary sewer service for the next 20 years. This planwill be updated every three to five years. One component of the plan was the determination of Inflow and Infiltration (I/I) Flows in 2000 and 2001. The results of this effort provide the data used in the development of the City's hydraulic sewer model in • 2006. 2.3 SYSTEM COMPONENTS The purpose of a sanitary sewer is to convey wastewater from its source to a point of treatment. Since the generation of wastewater can vary considerably, there is seldom any control over the volume of wastewater that must be conveyed at any particular time. For this reason the sanitary sewer system is designed to accommodate a wide range of wastewater flow rates. The best method for conveying wastewater is a gravity sewer system. A gravity sewer system is made up of collector sewers, which as their name implies, collect the wastewater from the various sources. These collector sewers then convey the wastewater to interceptor sewers, which convey it to the point of treatment. The sanitary sewer system must be capable of transporting all of the constituents of the wastewater stream, which include the suspended solids, floatable solids and liquid constituents. In general, most of the floating materials are carried along with the flow stream; however, suspended solids have a tendency to settle out of the waste stream, unless minimum carrying velocities are achieved. This requires that the sanitary sewers be Final 2010 2-3 constructed with a minimum slope to create a gravity flow that will result in a velocity that will continuously carry the suspended solids portion of the waste stream. Another major sewer system component, and typically the most vulnerable, is the sewage lift station. A lift station is needed when the sanitary sewer system must overcome topographic restrictions that make it impossible or financially unfeasible to construct a gravity sewer. However, some lift stations are temporary, used only until the gravity sewer system can be built. 2.4 WASTEWATER COLLECTION BASINS The City is divided into six major wastewater collection basins that consist of one or more model basins. The model basins were developed by King County's Ill Program for the Renton Sewer Service Area. These collection basins and model basins would ideally follow the natural drainage patterns of the Renton service area. However, because of natural and service area boundaries, the wastewater collection basins do not always follow drainage basins. The six major basins are 1) West Cedar River, 2) East Cedar River, 3) East Lake Washington, 4) Black River, 5) Downtown, and 6) May Valley. The City has lift stations and deep interceptors that transfer flows from one drainage basin to another. Figure 2.2 shows the topography of the City overlaid by the existing sewer system. 2.4.1 West Cedar River Basin The West Cedar River Basin includes the eastern portion of the City bordering the Cedar River. This basin, which consists of primarily single-family and multi-family developments with some commercial and light industrial land uses. This basin includes modeling basins CEDAR02 and RNT065. This basin includes the Cottonwood, Falcon Ridge, and Kensington Crest Lifts Stations. The wastewater collected in this basin is transported to King County's Cedar River Trunk Interceptor at several connection points (Table 2.1). 2.4.2 East Cedar River Basin The East Cedar River Basin is located at the east side of Renton's sanitary sewer service area. The basin extends from approximately Bremerton Avenue NE to the Urban Growth Boundary east of the City. The majority of this basin is currently unsewered and consists of primarily single-family land uses. A significant portion of this basin is already developed with subdivision. The majority of these developments are on private septic systems. Problems with some of the existing septic systems, the needs of the schools in the area, the lack of ability to develop existing platted lots on septic systems are, and the desire by some to develop some of the larger tracts in the area highlight the need for sanitary sewers in this basin. The basin can be partially served by gravity through the East Renton Interceptor. The Central Plateau interceptor is currently under construction. To serve the East Plateau subbasin, a new interceptor or a lift station constructed to transfer flows back Final 2010 2-4 ...1wi,,,, ,irip,,,-w Ni.,1---0,_ •.--Nwir., r IT --N..:'.-'- _7-.::=- .,..._1...a....,-!1‘ 411, r .

This basin includes the East Renton, Evendell, and Highlands Estates Lift Station. The wastewater collected in this basin is transported to King County's Cedar River Trunk Interceptor at several connection points (Table 2.1). 2.4.3 East Lake Washington Basin The East Lake Washington Basin is located in the northern part of the City and includes Model Basins RNT023, RNT030, RNT035, and RNT054. The City serves this entire basin, which consists of a'variety of land uses including single-family and multi-family residential, and light commercial. The wastewater collected in this basin is transported to King County's East Side Interceptor at several connection points (Table 2.1). This basin includes the Devils Elbow, Lake Washington Beach, Lake Washington Flush, Lake Washington No. 2, Long, Stonegate, Summerwind, Wedgewood, and Westview Lift Stations. 2.4.4 Black River Basin The Black River Basin is a large drainage basin in the southwest part of the City and includes the Model Basins SINT001, SRENT002, and RNT045. The higher elevations in the Rolling Hills, Talbot Hill, and Panther Creek areas are generally single-family and multi- family residential developments along with commercial uses surrounding Valley Medical Center, while the valley floor is generally industrial and commercial land uses. A large portion of the south and west portions of the valley floor are un-modeled. The upper elevations of this basin are served by Soos Creek. This basin includes the East Valley, Lind Avenue, and Talbot Crest Lift Stations. The wastewater collected in this basin is transported to King County's East Side, South Renton, and South Interceptors at several connection points (Table 2.1). 2.4.5 Downtown Basin The Downtown Basin is located in the northwest part of the City and includes the Central Business District, West Hill, and North Renton Industrial areas. Land use within this basin consists of single-family, multi-family, commercial, and heavy industrial land uses. This model basin includes the Airport and Earlington Lift Stations. Skyway Water and Sewer District also provides sewer service to parts of the West Hill that are within this basin. The wastewater collected in this basin is transported to King County's East Side Interceptor at several connection points (Table 2.1). 2.4.6 May Valley Basin The May Valley Basin is located in the northeast part of the City and is located on the periphery of the City's current service boundary. The portion of this basin within Renton's service area is currently only about half sewered. The remainder of the basin is within Coal • Creek Utility District's service area. The City serves primarily single-family and light commercial land uses. The ultimate sewerage of the southwest (City's) portion of the basin Final 2010 2-6 that is east of the freeway will be through the extension and completion of an interceptor to the south. Said interceptor to serve that portion of the basin would be mostly constructed in existing roads. It is unclear whether development will occur within this portion of the basin due to steep slopes, wetlands, and other sensitive area issues. This basin includes the Baxter, Dennys, and Misty Cove Lift Stations. The wastewater collected in this basin is transported to King County's May Creek Interceptor and East Side interceptor at several connection points (Table 2.1). 2.5 INTERCEPTORS AND COLLECTION SYSTEMS Interceptors are sewers that receive flow from collector sewers and convey wastewater to a point for treatment or disposal. They are typically located in low lying or centralized areas in order to facilitate the gravity flow of the wastewater. The interceptors and all other sewers make up the collection system. Standards and guidelines for design and construction of sanitary sewers are detailed in Chapter 4. The City has approximately 191 miles of gravity sewer within its service area as shown in Figure 2.3. The sanitary sewer collection system is primarily comprised of 8-inch diameter sanitary sewers but includes pipes sized from 6 to 24 inches. 2.5.1 Existing Sewers The existing sanitary sewer system is constructed with a variety of different sewer sizes and pipe materials. Figures 2.4 and 2.5 summarize the lengths of pipe for the different pipe diameters and materials. These totals include both gravity and force main pipe. As illustrated in Figure 2.2, a majority of the sanitary sewer system is constructed with 8-inch diameter pipe. This is consistent with the Department of Ecology criteria for minimum sanitary sewer sizing. The majority of pipe material within the existing system is comprised of concrete and polyvinyl chloride (PVC) pipe. The concrete pipe has been typically used. for the older sewers, while the PVC pipe has been typically used for newer sewer system installations. The City's sanitary sewer system also contains approximately 5,100 manholes, which join the various links of sanitary sewer pipe. These manholes vary in construction type from old brick manholes to the newer precast concrete manholes. A small percentage (2-4 percent) of the older manholes do not meet current code for safety such as manhole covers that are less than 24-inches in diameter.

The wastewater flow rates into each of these connections varies considerably, depending on the area served by the collection system. The major King County connections for each basin are listed in Table 2.1. 2.6 LIFT STATIONS Sewage lift stations are used to convey wastewater from a low point to a higher point through the use of a sewage pump and a pressurized force main. The City has 23 sewage lift stations within its sanitary sewer system as is shown in Figure 2.6 and summarized in Table 2.2. Data sheet for each lift station are include in Appendix B. Since the last Comprehensive Plan in 1999, 4 lift stations have been removed due to consolidated efforts and 6 lift stations have been added. The most common type is a submersible pump installation in which the sewage pumps are placed directly in the wet well. The second most common type is a wet well mounted lift station in which the mechanical and electrical equipment are located above the ground surface and over a large manhole out of which the wastewater is pumped. A wet well/dry well configuration is the third most common type of station. This type has mechanical and electrical equipment located underground in a sealed enclosure adjacent to a large manhole from which the wastewater is pumped.

LIFT STATIONS . . •eP— JANUARY 2008 Sewage lift stations are the most vulnerable element of a sewage collection system. Permanent lift stations are constructed when it is either physically impossible or financially impractical to construct gravity sewers. Temporary lift stations are constructed when it is too costly, at that time, to complete the gravity sewer system. Temporary lift stations are, however, usually built to permanent standards, since it may be hard to predict when the gravity facilities will be available. 2.6.1 Airport Lift Station The Airport Lift Station is located on the east side of West Perimeter Road within the airport property. This facility is a fiberglass, wet well mounted, duplex lift station with a duplex vacuum priming system. This facility serves the airport facility along West Perimeter Road.

In 2005, the City did some improvements to improve accessibility into the station. The Misty Cove Lift Station pumps to the Baxter Lift Station, which has a smaller wet well. For this reason a lockout has been placed on the Misty Cove Lift Station, which is engaged when the high level alarm at the Baxter Lift Station is activated. The Baxter Lift Station is being replaced as part of a large residential development along the lakefront, The lockout will be evaluated and may remain for system reliability purposes. 2.6.19 Stonegate Lift Station The Stonegate Lift Station is located on NE 26th Street just west of 148th Avenue SE. The station is on the north side of the road in an open space tract. This facility is a fiberglass enclosed, wet well mounted duplex lift station with a duplex vacuum priming system. The facility serves the entire plat of Stonegate as well as two new plats to the south. This station is dependent on the Summerwind Lift Station to relay the sewage from this area to the gravity system. Analysis shows that the station is undersized to meet the build out needs of this area. Increased flows from the Stonegate Lift Station would impact the Summerwind Lift Station. A capital project, currently in pre-design, will redirect flows from Final 2010 2-18 the Summerwind Lift Station to a new Stonegate Lift Station that will pump to a new field interceptor. ' 2.6.20 Summerwind Lift Station The Summerwind Lift Station is located in a fenced, storm-drainage retention area located off the cul-de-sac on NE 23rd Street. This facility is a fiberglass enclosed, wet well mounted duplex lift station with a duplex vacuum priming system. This facility serves the east half of the plat of Summerwind. The lift station has proven to be reliable but is reaching the end of its useful life. The Stonegate Lift Station pumps into the Summerwind Lift Station. The Stonegate Lift Station is undersized to meet the build out needs of this area. The Summerwind station does not have the capability to handle additional flows from a larger Stonegate Lift Station, as such, Summerwind Lift Station flows will be redirected to a new, properly sized Stonegate Lift Station. 2.6.21 Talbot Crest Lift Station The Talbot Crest Lift Station is located on the west side of Talbot Crest Drive.

This facility is a submersible pump duplex station, which serves the plat of Wedgewood, as well as the surrounding basin area. This station allowed for the elimination of the Scott Glen and Apollo Lift Stations. The station was constructed in 2006. 2.6.23 Westview Lift Station The Westview Lift Station is located on the west side of Monterey Avenue NE. This facility is a duplex submersible lift station designed to serve the twelve lot Westview Plat. Unless a gravity line is installed from Park Drive, this station should be considered a permanent station. This station was originally constructed in 1995. This station was allowed to be constructed to a lower standard resulting in a scheduled rehabilitation/replacement date of 2009, well ahead of our standard 25-year life. 2.7 TELEMETRY AND CONTROL SYSTEM Successful operation of any municipal sewer system requires that the municipality maintains a comprehensive maintenance program and that they obtain accurate sewage flow rate information. Although many additional operation and construction elements are necessary for a complete and working system, maintenance and flow rate information are Final 2010 2-19 • the keys to a successful operation. A telemetry and control system is the means by which flow rates are measured and maintenance needs are updated. A radio-based telemetry system was completed in 1996 to replace the City's existing tone telemetry system. Each lift station is controlled by a digital based Remote Telemetry Unit (RTU) to allow custom control to match the characteristics of each individual lift station. The RTU are programmable controllers programmed in basic programming language. The RTU monitors the control at the lift station and provides secure and accurate information about the operating conditions. A Master Telemetry Unit (MTU) polls each lift station RTU and feeds the data to the Master Computer via a Modbus communication link. The new system is digital, signal-based, using a high security, binary coded decimal for telemetry transmission. The system runs on IBM compatible computers. The system uses radio transmission for communication. The telemetry system provides a method for logging and controlling all of the City's lift stations from a central location at the City's Maintenance shops. Operating data from each lift station is stored on a Master (data-logging) Computer for record and later use. This information is used in a comprehensive maintenance program to help eliminate costly station down time that can often cause damage to adjacent property owners and the environment. The control algorithms located on the Master Computer and the RTUs can be used as trend analysis to detect possible problems earlier. The telemetry system information is managed from a Master computer. Wonderware Intouch Person-Machine Interface software is used at the Master Computer for displaying the data graphically on screen. The Master computer displays wet well sewage levels and time to overflow data for the City's 25 lift stations (two of the 25 stations are storm water stations). This information can be used to help manage the lift stations in a citywide power interruption that could occur after a natural catastrophe. The telemetry system can be monitored and controlled by a remote computer link using specialized software. Control of the facilities is accomplished in a distributed format, wherein the master computer provides pump run set points that are based on optimal, pump operating conditions, and also locks out various lift stations during high-level alarms from various downstream lift stations. All other control is initiated from the RTU, including pump start/stop from the level transducer, back-up pump control from the float switches, and station alarms. The,pumps main control system is controlled from a level sensor in the wet well. A back-up float switch system has been installed at most of the lift stations to provide redundant protection from costly overflows in the event of control failure. Smaller stations, serving twelve or fewer single-family homes, may utilize floats as the main control system. The system uses strain gauge, level transducers that are suspended in the wet well for primary pump control and uses float switches for back-up pump control in the event of Final 2010 2-20 transducer failure. Pump discharge flow rates are mathematically synthesized by measuring the time it takes to empty a known volume of the wet well. The engineering and system status information that is presented at the City Shops is available in real time format at City Hall using a secure network. This allows the engineering and planning staff access to system information without disrupting the maintenance staff. The computer and data storage system is compatible with the water data logger to provide redundant data storage and to provide hot standby fail over controllers. Operating data from each lift station is stored on the master computer for record and later use. This information is used in a comprehensive maintenance program to help eliminate costly station down time that can often cause damage to adjacent property owners and the environment. The control algorithms located on the Master Computer and the RTUs can be used as trend analysis to detect possible problems earlier. The master telemetry unit, located at the City Shop, includes an intelligent telephone dialer alarm systems, so that critical alarms can be relayed to on-duty maintenance personnel, even during a telemetry system failure. 2.8 OPERATION AND MAINTENANCE The current operation and maintenance program for the sewer utility consists of four elements: normal operations, emergency operations, preventive maintenance and staffing. Normal operation of the sewer system is shared by the Engineering Division and the Operation and Maintenance Division. The program is described and evaluated in more detail in Chapter 7. Final 2010 2-21 Chapter 3 OPERATIONAL POLICIES 3.1 INTRODUCTION The existing sewer system is designed and operated according to specific ordinances, regulations and engineering standards (hereafter collectively referred to as policies). All of the policies originate from eight sources, listed in descending order, from those with the broadest authority to those with the most narrow: • Federal Regulations - Environmental Protection Agency • State Regulations - Department of Ecology • King County Policies - Department of Natural Resources -Wastewater Treatment Division • • City of Renton Comprehensive Plan • City of Renton Ordinances - City Council • Administrative Policies - Mayor • Department Policies - Public Works Department • Long-Range Wastewater Utility Policies -Wastewater Utility Staff Federal regulations, state regulations, county policies, and city ordinances dictate requirements that are set by law. Policies that originate in the Office of the Mayor, Public Works Department, or Wastewater Utility cannot be less stringent or in conflict with those laws. This chapter defines the long-range wastewater policies that will become the official policy of the Wastewater Utility when the City Council adopts this LRWWMP. This chapter also summarizes relevant federal, state, and city ordinances and laws. 3.2 GOAL The goal of the City of Renton Wastewater Utility is to provide adequate, reliable sanitary sewer service at a minimum cost to the customer. Guiding the Wastewater Utility's daily operations as well as its planning activities, the policies in this LRWWMP stem from this goal. Objectives and policies that fall into four areas of emphasis support this broad service goal: 1. Customer Service 2. Financial Final 2010 3-1 3. Facilities 4. Organization 3.3 WASTEWATER UTILITY POLICIES AND REGULATIONS The City's long-range wastewater policies, City ordinances, and State regulations are summarized below. The policies presented herein will become the official policies of the Wastewater Utility when the City Council adopts this LRWWMP. Consequently, they are presented in the traditional policy format rather than the outline format that the other chapters follow. For the actual wording, refer to the indicated sources for the complete text. 1.0 CUSTOMER SERVICE OBJECTIVE: Ensure the availability.of an adequate level of sanitary sewer service that is consistent with land use, environmental protection, and annexation goals and policies. • POLICIES: 1.1 Sewer facilities and services should be consistent with the growth and development concepts directed by the Comprehensive Plan (Policy U-1, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004'as amended). 1.2 Ensure and encourage the use of the sanitary sewer system within the urban areas _ in a manner consistent with land use and environmental protection goals and policies (Policy U-55, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). 1.3 All new developments should be required to connect to the sanitary sewer system, except properties zoned for low density single family residential development that are located away from environmentally sensitive areas, outside of Aquifer Protection Areas, and having adequate soils to support on-site septic systems (Policy U-56, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). 1.4 Actively promote connection to the public sewers by all residents within the City's service area (Policy U-72, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). • 1.5 Public Sewer expansions shall not occur in the Rural Area and on Natural Resource Lands except where needed to address specific health and safety problems threatening the existing structures or the needs of public schools or public school facilities (Policy F-249, 2004 King County Comprehensive Plan with 2006 amendments, adopted November 1, 2004 as amended). Final 2010 3-2 EXISTING REGULATIONS: 1.6 Private sewage disposal systems will be allowed within the urban areas, subject to city, county, and state regulations and when public sewers are not available (City Code Sections 4-6-040.A.1). 1.7 The owners of private sewerage disposal systems shall operate and maintain the facilities in a sanitary manner at all times at no expense to the City (City Code Section 4-6- 040.1.4). 1.8 The owner or occupant of lands or premises located within the urban growth area (as defined in the King County Comprehensive Plan) undertaking new residential or nonresidential construction, short subdivision or subdivision from which sewage will originate shall connect to a public sewer, provided the sewer utility permits such connection (King County Board of Health Rules and Regulations No. 3, 13.04.050). 1.9 Sanitary sewers, together with all appurtenances, shall be constructed or deferred before a final short plat is submitted or a short subdivision is recorded. Sanitary sewers shall be constructed to specifications and standards of the Wastewater Utility, approved by the Department and in accordance with other standards of the City. A separate construction permit will be required for any such improvements, along with associated engineered plans prepared per the City drafting standards and associated fees (RMC 4-7- 070J). 1.10 Unless septic tanks are specifically approved by the Planning/Building/Public Works Department and the King County Health Department, sanitary sewers shall be provided by the developer at no cost to the City and designed in accordance with City standards. Side. sewer lines shall be installed eight feet (8') into each lot if sanitary sewer mains are available, or provided with the subdivision development (RMC 4-7-070J). 1.11 . Existing development that is within two hundred feet (200') of a public sewer, where an on-site system (OSS) is operating, connection to the public sewer is required when the sewering authority permits such connection and when: a. Repair, modification, or replacement of the system is necessary, or the existing OSS has failed and an OSS fully conforming to this title cannot be designed and installed; or b. At such time that additional construction which in any way affects the on-site sewage system is proposed (King County Board of Health Rules and Regulations No. 3, 13.04.050). c. They are part of a sewer Local Improvement District (LID) (City Code Section 4-6-040.A). 1.12 Any new development (residential and non-residential) in Zone 1 of the Aquifer Protection Area (APA) shall be required to connect to the City sewer system (City Code Section 4-6-040J.1.a.i). Final 2010 3-3 1.13 Existing development (residential and non-residential) in Zone 1 of the APA that is within the specified proximity of existing or future gravity sanitary sewer shall be required to connect to the City sewer system within two (2) years of the availability of the new sewer line (City Code Section 4-6-040J.1.a.iii). 1.14 Any new development (residential and non-residential) in Zone 2 of the Aquifer Protection Area shall be required to connect to the City sewer.system (New single-family residential development on existing lots may be allowed to use on-site disposal systems until public sewer service becomes available, as determined by the Wastewater Utility) (City Code Section 4-6-040J.2.a.i). 1.15 The City, at the discretion of the Wastewater Utility, may defer compliance with non- health related standards dealing withextension, design, or capacity for temporary sanitary sewer service. Temporary sanitary sewer service may include pump tests, temporary discharge permits, connections for temporary construction sights, or other similar usage. The property owner will retain the responsibility and will execute an agreement to either directly or financially meet said standards at the direction of the City (City Code Section 4- 9-250). 1.16 After connection to the sewer system, all private sewage disposal facilities shall be abandoned and filled with suitable material as defined by current Seattle-King County Health Department regulations, or upon proper cleaning, may be used to dispose of storm waters (City Code Section 4-6-040.1.6). 2.0 PLANNING OBJECTIVE: Ensure that Renton's sewage collection system is consistent with the City's land use plans and the public health and water quality - goals of Washington State. POLICIES: 2.1 Coordinate the extension of sewer service with expected growth and development (Policy U-13, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). 2.2 Apply level of sanitary sewer service standards consistently throughout the service area (Policy U-14, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). 2.3 Preference should be given to sewer system improvements that will support high growth areas concurrent with the anticipated growth (Policy U-15, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). 2.4 Timely and orderly extension of the sewer system should be provided within the City's existing and future service areas to meet public heath requirements (Policy U-17, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). Final 2010 3=4 2.5 Implementation and coordination of programs for the improvement, phasing and financing of sewer infrastructure should be developed consistent with the Land Use Element of the Comprehensive Plan (Policy U-19, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). 2.6 Development should be required to pay an equitable share of construction costs for improvements to the sanitary sewer system (Policy U-20, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). 2.7 Adequate sewer service capacity should be assured prior to-the approval of any new development application (Policy U-58, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). 2.8 Sewer facilities and services should be in place prior to occupancy of development projects (Policy U-18, 2004.City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). 2.9 Sewer service should be expanded so that the current levels of service are maintained through build-out of the adopted land use (Policy U-59, 2004 City of Renton Comprehensive Plan, adopted November 1, 2004 as amended). Note: While land use plans typically deal with twenty-year projections, the sewer facilities installed today have a life expectancy of 75 to 100 years. A Sanitary Sewer Utility has to consider the current Land Use Plan, historical trends, and predictions for further growth when designing sewers. The Utility may install a facility larger than needed for the land use projected in the twenty-year plan if additional capacity needs are projected for the long- term future. It is in the best interests of the ratepayers to obtain the longest use possible from a facility and not have to replace newer facilities. 2.10 Renton should coordinate with the regional wastewater agency and adjacent jurisdictions in the planning and maintenance of regional wastewater systems in and near the City (Policy U-61, 2004 City.of Renton Comprehensive Plan, adopted November 1, 2004 as amended). 2.11 For planning purposes, the Wastewater Utility should use sanitary sewer service boundaries established by agreement with adjacent municipalities. Where boundaries do not exist, the Wastewater Utility shall use natural basins, the County's Urban Growth Boundary, and negotiations with adjacent sewer service providers to determine the ultimate service area (LRWWMP). 2.12 Facilities should be planned and sized to serve natural basins to minimize the need for pumping and inter-basin transfers (LRWWMP). 2.13 Projected sewage flows from development should be calculated based on adopted land use plans and policies. These projections should be used as a guide in developing the Final 2010 • 3-5 wastewater Capital Improvement Program (CIP). If and when land use plans and policies are revised, the CIP should be adjusted accordingly (LRWWMP). 3.0 SERVICE AREA EXTENSION OBJECTIVES: Ensure the availability of an adequate level of sanitary sewer service to areas annexing to the City or areas within the City's Potential Annexation area. POLICIES: 3.1 The City of Renton will follow state guidelines that define a City's ability to assume facilities in annexation areas (RCW 35.13A and 2004 Renton Comprehensive Plan, Policy U-64). 3.2 The City may assume existing portions of adjacent sanitary sewer systems, at the discretion of the City Council, when such assumptions promote the logical and efficient development of the City's sanitary sewer system (Policy U-70, 2004 Renton Comprehensive Plan, adopted November 1,2004 as amended). 3.3 Allow the extension of sanitary sewer services within the City's Potential Annexation Area according to such criteria as the City may require. Sanitary sewer service shall not be established within the boundaries of another sewer service provider's district, except by agreement with that provider (Policy U-69, 2004 Renton Comprehensive Plan, adopted • November 1, 2004 as amended). Comment: As the service provider, Renton is the point of contact or focal point. Not all regulations or criteria originate with Renton. Some regulations or criteria originate at the federal, state, or county level. All applicable regulations will be followed in the provision of service in unincorporated areas. 3:4 Areas annexed without existing municipal sanitary sewer service shall be served by Renton unless a service agreement exists or is negotiated with a neighboring utility (RCW 35.13A.050 and Policy U-65, 2004 Renton Comprehensive Plan, adopted November 1, 2004 as amended). 3.5 Areas annexed with existing sanitary sewer service must meet the City's sanitary sewer service objectives. Upgrading of sanitary sewerfacilities to City standards, within all or portions of newly annexed areas will be required if there is a threat to public health and safety. If improvements are necessary, they may be accomplished by developer installation or LID as a condition of the annexation (Policy U-66, 2004 Renton Comprehensive Plan, adopted November 1, 2004 as amended). 3.6 The City Council shall consider annexations without assumptions of existing sanitary sewer facilities under the following conditions: a. The sanitary sewer facilities are or will be operated and maintained by an adjacent municipal utility; and Final 2010 3-6 b. The adjacent utility has executed a service boundary agreement with the City; and c. The annexation area.is better served by the adjacent utility either because of location within a drainage basin or because it is the most logical extension of facilities (LRWWMP). 3.7 When areas outside of the city limits annex to the City, they must be provided with an adequate level of sewer service. The City of Renton will serve annexed areas that do not have sewer service unless a service agreement exists or is negotiated with a neighboring utility..Annexed areas with existing sanitary sewer service must meet the City's sanitary sewer service objectives as they are defined within the LRWWMP. However, upgrading sanitary sewer facilities to all City sanitary sewer standards will be required only if there is a threat to public health and safety. As a condition of the annexation, improvements may be required, which can be constructed by developer installation or LID (LRWWMP). 3.8 In the Urban Growth Area all new development shall be served by public sewers, unless application of this policy to a proposal for a single-family residence on an individual lot would deny all reasonable use of the property (2004 King County Comprehensive Plan • with 2006 Amendments, Policy F-245). 3.9 King County shall work with cities, special purpose districts, and other local service providers and citizens to identify and distinguish local and countywide services. Over time, cities will assume primary responsibility for coordination the provision of local services delivery. The County will assume primary responsibility for coordinating the provision of countywide services, including countywide services that must be delivered within city boundaries. The County will also work with cities, special purpose districts, and other counties to identify regional services and facility needs, and develop strategies to provide them (2004 King County Comprehensive Plan with 2006 Amendments, Policy F-102). EXISTING REGULATIONS: 3.10 Sanitary sewer service to properties outside the City's corporate limits will not be permitted except under the following conditions: a. Public Entity: The applicant is a municipal or quasi-municipal corporation including a school, hospital or fire district, County of King, or similar public entity; or b. Necessary Service: Service is necessary to convert from a failed or failing septic system or in the area that has been defined by the Seattle-King County Health Department as a health concern area; or c. Vested Service: Those properties for which the City has granted a valid sewer availability certificate prior to July 21, 2008 and the project has a current vested right to build; or d. In the City's Sewer Service Area, Existing Legal Lot(s) Desiring to Construct One Single-Family Residence or Connect One Existing Single Family Final 2010 3-7 Residence: The Administration may approve the connection of one single- family residence on an existing legal lot. In any case, as a condition of sewer service by the City of Renton, the property owner(s) shall execute a covenant to annex for each parcel when the property being provided sewer service is within Renton's Potential Annexation Area (PAA) (City Code Section 4-6-040.C). 4.0 FINANCIAL OBJECTIVE: Provide sound financial policies on which to base operations of the Wastewater Utility that will allow the utility to meet its overall goal. POLICIES: • 4.1 Criteria should be established for developing the fees and rates necessary to maintain the Wastewater Utility's established level of service (LRWWMP). 4.2 The Wastewater Utility shall be operated as an enterprise utility (financially self- supporting) (LRWWMP). 4.3 The Wastewater Utility should use a rate setting process that complies with standards established by the American Public Works Association (LRWWMP). 4.4 The Wastewater Utility should use cost-based rates and additional charges that: a. Recover current, historical, or future costs associated with the City of Renton's sanitary sewer system and services. b. Equitably charge utility customers to recover costs commensurate with the benefits they receive. c. Provide adequate and stable sources of funds to cover the current and projected annual cash needs of the Wastewater Utility (LRWWMP). 4.5 Portions of the revenue generated from sewer user rates will be used for wastewater utility related capital improvement projects, including debt service for the projects (City Code Section 8-5-15F). 4.6 New customers seeking to connect to the sanitary sewer system shall be required to pay charges for an equitable share of the cost of the system. Revenue from these charges is used to finance part of the CIP (City Code Section 4-1-180.C). 4.7 Customers should be charged for supplemental, special purpose services through separate ancillary charges based on the cost to provide the service. Ancillary charges create more equitable fees and increase operating efficiency for services to customers. Revenue from ancillary charges should be used to offset operations and maintenance costs (LRWWMP). 4.8 The utility should maintain information systems that provide sufficient financial and statistical information to ensure conformance with rate-setting policies and objectives (LRWWMP). Final 2010 3-8 4.9 Rates shall be developed using the cash basis to determine the total revenue requirements of the Wastewater Utility (LRWWMP). 4.10 User charges shall be sufficient to provide cash for the expenses of operating and maintaining the Wastewater Utility. To ensure the fiscal and physical integrity of the Wastewater Utility, an amount shall be set aside each year for capital expenditures from retained earnings, that is, an amount shall be set aside to cover some portion of the depreciation of the physical plant. The amount may be transferred from the Sanitary Sewer Fund to the Construction Fund for general purposes, or for specific purposes, such as creating a reserve for main replacement (LRWWMP). 4.11 A Working Capital Reserve will be maintained to cover emergencies, bad debts, and fluctuations in cash flow (LRWWMP). 4.12 The customer classes for the utility shall be single-family (including attached single- family), commercial (including multi-family), and industrial (City Code Section 4-6-040.E.2). 4.13 The inflation rate should be based on information provided by the Finance Department (LRWWMP). 4.14 Large industrial users should be charged for services on the same basis as all other users (LRWWMP). 4.15 The utility should use generally accepted cost allocation principles for all cost allocation purposes (LRWWMP). 4.16 The utility fees and charges should be calculated for the service area as a whole. Rates should be the same regardless of location (except for the inside/outside City distinction discussed below) (LRWWMP). 4.17 When the City takes over existing service of properties outside the City limits by agreement with an adjacent district, the City shall charge the normal in-city rates (LRWWMP). EXISTING REGULATIONS: 4.18 For customers residing outside the City limits, sanitary sewer rates are 1.5 times the residential City rates (City Code Section 8-5-15C). 4.19 Renton provides for a senior and/or disabled citizen discount on City sewer rates (City Code Section 8-5-15D4). 4.20 Owners of properties that have not been assessed or charged an equitable share of the cost of the sanitary sewer system shall pay, prior to connection to the system, one or more of four charges: a. System Development Charge Final 2010 3-9 b. Special assessment charge c. Latecomer's fees d. Inspection/approval fees (City Code Sections 4-1-180.C, 4-1-180.D, and 4-1- 180.E) 5.0 FACILITY OBJECTIVE: Provide a wastewater collection system that ensures adequate capacity and system reliability, is consistent with land use and environmental protection goals and policies, and is well maintained. POLICIES: 5.1 Design criteria should be established to provide an optimum performance level and a standard of quality for the sanitary sewer system (LRWWMP). 5.2 All lift stations that will be converted to public maintenance shall have control and telemetry systems that are consistent and compatible with the current City system (LRWWMP). 5.3 Joint use facilities will be pursued only in those areas where they,would improve reliability or reduce operating costs. All joint use facilities must comply with City policy and design standards (LRWWMP). EXISTING REGULATIONS: 5.4 Public sewers shall conform to the latest standards of the City of Renton, as adopted by City Code as well as the Department of Ecology Criteria for sewage works design.and the Recommended Standards for Sewage Works of the Great Lakes-Upper Mississippi River Board of State Sanitary Engineers.

All public sewer extensions shall conform to City standards and be consistent with the City LRWWMP (City Code Section 4- 6-040.F.2). • 5.5 The public sewer shall be ductile iron American Water Works Association (AWWA) C 151, that is with Type II push-on or Type III mechanical joints, together with cement mortar lining that is 3/32 of an inch in accordance with AWWA C 104, or polyvinyl chloride (PVC) plastic pipe American Society for Testing Methods (ASTM) D 3034, or concrete non- reinforced ASTM C14 Class 2, or concrete reinforced ASTM C76. Rubber gaskets for concrete pipe shall meet ASTM C443 standards. Rubber gaskets for PVC pipe shall meet ASTM 1869 standards. However, public sewers installed in filled or unstable ground, in areas with high ground water levels, or in areas where the potential for infiltration occurs, may be required to be either ductile iron, or PVC plastic pipe. Exact pipe material shall be as determined by the Wastewater Utility. Alternative pipe materials may be considered by the Wastewater Utility on a case-by-case basis. Minimum size shall be 8 inches in diameter (City Code Section 4-6-040.F.3). Final 2010 3-10 5.6 Manholes shall be installed at the end of each line, at all changes of grade, size or alignment, and at distances no greater than 400 feet for 15-inch diameter sewers or smaller. Greater spacing may be permitted in larger sewers. Manholes shall be a minimum of 48 inches in diameter, shall be precast concrete or cast in place concrete, with steel reinforcement. Steps shall be placed at 1-foot intervals, conforming to current safety regulations. The manhole covers shall be 24-inch diameter cast iron frame and lid. All connections to the manhole shall match the existing inverts or have a drop connection in accordance with standards (City Code Section 4-6-040.F.5). 5.7 All private lift stations for commercial or multi-family use shall have alarm and standby emergency operation systems, and meet or exceed Department of Ecology specifications as detailed in Recommended Standards for Sewage Works. All private single-family lift stations shall meet or exceed City standards for that type of facility (City Code Section 4-6-040.F.6). 5.8 All person(s) or local improvement districts desiring to extend sanitary sewer mains as part of the City's system must extend said mains under the supervision of the Wastewater Utility (City Code Sections 4-6-040.F.7). 5.9 No property shall be served by City sewer unless the sewer main is extended to the extreme boundary limit of said property as required by this section. All extensions shall extend and cross the full width of the property to be served by sewer except when shown by engineering methods, to the satisfaction of the Wastewater Utility, that future extension is not possible or necessary. If an exemption is granted, the property owner is not relieved of the responsibility to extend the main and shall execute a covenant agreeing to participate in an extension if, in the future, the Wastewater Utility determines that it is necessary (City Code Sections 4-6-010.6). 5.10 Any facility improvements, identified by the current adopted LRWWMP, that are not installed or are being installed must be constructed by the property owner(s) or developer(s) desiring service (City Code Sections 4-6-040.6). 5.11 Any party extending utilities that may serve other than that party's property may request a latecomers' agreement from the City (see City Code Chapter 5, Title IX for methodology) (City Code Sections 9-5-1). 5.12 Any party required to oversize utilities may request that the utility participate in the cost of the project (City Code Section 4-6-010.C). 5.13 ' Grease and oil interceptors or other approved methodology, shall be required on all restaurant, garage, and gas station premises and shall be so situated as to intercept the sources of grease and oil wastes but exclude domestic or human wastes. Grease, oil, and { sand interceptors shall be provided in any other case if, in the opinion of the Wastewater Final 2010 . ' .. 3-11 Utility, they are necessary for the proper handling of liquid wastes. All interceptors shall be ( of a type and capacity approved by the Wastewater Utility (City Code Section 8-5-11). 5.14 Old building sewers may be used in connection with new buildings only when, after examining and testing them, the Wastewater Utility finds they meet all standards and specifications of the City (City Code Sections 4-6-040.G.13). 5.15 The size and slope of the building sewer shall be subject to the approval of the Wastewater Utility. The standard minimum sizes and slopes are (City Code Sections 4-6- 040.G.3): a. 4'inches;.at a 2 percent slope (1/4 inch per foot) for single-family residential. b. 6 inches at a 2 percent slope (1/4 inch per foot) for multi-family, commercial, or industrial. In no event shall the diameter of the side sewer stub be less than 6 inches. The Wastewater Utility may allow, under certain circumstances, a 6-inch side sewer to be laid at no less then 1 percent (1/8 inch per foot). A grade release holding the City harmless for the flatter slope will be required. 5.16 If a building cannot be served by a gravity system an approved, private lift station may be utilized to provide service (City Code Sections 4-6-040.G.5). 6.0 MAINTENANCE OBJECTIVE: Maintain the sanitary sewer system in a safe, reliable, and efficient operating condition. POLICIES: 6.1 The City will maintain its wastewater collection system according to the following guidelines: • a.

Spare parts shall be stocked for all equipment items whose failure will impact either the ability to meet other policy standards or the inability to continue providing service to customers (LRWWMP). 6.2 The City should provide a preventive maintenance schedule for all facilities and equipment. This schedule should be based on the functional and economically useful life of the equipment and facilities as determined by the manufacturer or industry experience. a. Worn parts should be repaired, replaced, or rebuilt before they have a high probability for failure. Final 2010 3-12 b. Where feasible and practical, equipment should be replaced before it becomes obsolete (LRWWMP). • _ 6.3 The City will maintain the wastewater collection system in a timely manner that provides service continuity to the customer. a. Equipment breakdown repairs will be made even if overtime labor is involved. b. Equipment that is taken out of service for maintenance will be returned to service as soon as possible (LRWWMP). 6.4 Written records and reports should be maintained on each facility and item of equipment showing its operation and maintenance history'(LRWWMP). 6.5 The property owner is responsible for and shall maintain side sewer stubs (that portion of the side sewer within the right-of-way or easement). If a side sewer becomes plugged, it is the property owner's responsibility to correct the problem. The City will assist in locating the side sewer based on any as-built records it has. If it is determined that the problem exists within the City sewer main, the City will provide professional clean up and repair service (LRWWMP). 6.6 A vulnerability analysis will be performed to determine a reasonable "worst case" failure for each basin. The analysis will consider the failure of the interceptor and trunk sewers, failure of the largest mechanical component, and power failure to a single power grid (LRWWMP). EXISTING REGULATIONS: 6.7 Restaurants and other food processing establishments, garages, and gas stations shall install and maintain grease traps, grease and.oil interceptors, or other approved methodology on their premises as determined by the Wastewater Utility (City Code Section 8-5-11). 7.0 ORGANIZATIONAL OBJECTIVE: Provide the organizational structure and staff necessary to operate the City of Renton's Wastewater Utility system efficiently: POLICIES: 7.1 The Wastewater Utility is responsible for operating the sanitary sewer system, including its planning, design, operations and maintenance, records management, customer service, and construction management (LRWWMP). 7.2 The Wastewater Utility shall consist of two sections: Wastewater Utility Systems Section and Wastewater Maintenance Section. The Wastewater Utility Systems Section is responsible for project management of CIP projects, planning and design, and customer service. Wastewater Maintenance Section is responsible for inspection, testing and repair of facilities, routine preventative maintenance, and responding to emergencies (LRWWMP). Final 2010 3-13 7.3 Wastewater Utility customer service is performed by the Planning/Building/Public • Works Customer Service Division (general) and by the Wastewater Utility staff (technical) (LRWWMP). 7.4 Provide the levels of-staffing and diversity of skills necessary to operate the City's wastewater utility system (LRWWMP). 7.5 The Wastewater Utility should utilize the expertise in other City departments, according to inter-departmental agreements, to augment the Wastewater Utility's expertise (LRWWMP). Final 2010 3-14 Chapter 4 PLANNING CONSIDERATIONS AND DESIGN CRITERIA 4.1 INTRODUCTION This chapter describes the City of Renton's land use policies, and the sewer system's design criteria. It then describes how land use policies and design criteria were used to develop saturation flow rates that were the basis for a hydraulic computer analysis of the existing system. The City of Renton's land use policies and its sewer system are connected with adjacent sewer systems' policies and systems in several ways. Existing land use provides the basis for designing properly sized sewerage facilities, including trunks, interceptors, and lift stations. Most of the basins served in part by the City are also served in part by other cities or districts. In most cases Renton's sewers are downstream, or at the receiving end of the effluent, from the systems adjacent to the City. Therefore, proper planning for Renton's sewers requires that the plans of these adjacent utilities be evaluated. In addition to adjacent utility plans, the land use plans and policies of King County and the Growth Management Planning Council were also considered. As discussed below the entire planning area is within the Urban Growth Boundary (UGB) established by the Growth - Management Planning Council. Renton supports the countywide framework policies (F-245 and F-102) that call for the designated Urban Area to be served with sanitary sewers and prefers cities as the provider of sewer services. The entire study area has been designated Urban by the 2004 King County Comprehensive Plan with 2006 Amendments. 4.2 PLANNING AREA The Planning Area for this LRWWMP was developed using a variety of criteria. Because many of the adjacent utilities have sanitary sewer facilities that border the Renton City Limits, the proposed sewer service area for the most part, corresponds with the current city limits and urban growth boundary, as shown in Figure 4.1. Deviations from this norm did occur in the following areas: - • As of the adoption of Renton's 1998 Long-Range Wastewater Management Plan, Renton's sanitary sewer service area has been extended to the UGB for the East Cedar River Basin, which coincides with Renton's Potential Annexation Area (PAA), extending to the urban growth boundary. Sewer extensions into this portion of the service area will be primarily driven by development within this basin and the need to provide public sewer to the three schools in the area. Consistent with the Countywide Planning Policies, the current Comprehensive Land Use Plan for the City of Renton has included the East Cedar River basin within the City's Planning Area.

CITY OF RENTON 1:24,000 i/ i Urban Growth Boundary LONG-RANGE WASTEWATER MANAGEMENT PLAN i ii City Limits Y SEWER SERVICE AREA C ,,- Sanitary Sewer Service Area ADJACENT SEWER UTILITIES N o� JANUARY 2008 • The City of Renton has negotiated service area boundaries along the common borders with Coal Creek Water and Sewer District, Soos Creek Water and Sewer District; Skyway Water and Sewer District, and Cedar River Water and Sewer District. The study area includes the agreed upon service area boundaries. • Natural boundaries in certain areas make the City of Renton the logical sanitary sewer provider to them. The study area includes a portion of the area to the east of the Green River within the City of Tukwila. As described in Chapter 2, the City of Renton serves six drainage basins, which are: 1) Black River, 2) Downtown, 3) East Cedar River, 4) East Lake Washington, 5) May Valley, and 6) West Cedar River. City of Renton, City of Tukwila, City of Kent, and Soos Creek Water and Sewer District provide service within the Black River Basin. Soos Creek Water and Sewer District also provides service within the Black River and West Cedar River Basins. Skyway Water and Sewer District serves parts of the Downtown Basin. May Valley Basin is partially served by Coal Creek Water and Sewer District. 4.3 LAND USE 4.3.1 • City Of Renton Land Use The existing land use pattern of the City of Renton reflects 100 years of settlement and expansion. The original City was settled in the broad floodplain at the confluence of the Cedar and Black Rivers along the shore of Lake Washington. The downtown, the Renton Municipal Airport, and the Boeing/PACCAR industrial area now occupy these lands. Significant redevelopment is anticipated for the downtown and portions of the former Boeing industrial area over the next 15 to 20 years. The Landing Development sits on approximately 60 acres of former Boeing Industrial Land. This development currently consists of various retail uses and a significant multi-family component. This development will continue to expand within its existing 60-acres over time as current surface parking is replaced by structured parking, thus permitting future infill of additional retail, residential, and commercial office applications. Phase II of the landing includes an additional approximate 30 acres of land for similar uses as phase I. The initial development of the Landing was a partnership between the City and the developer Harvest Partners. The City installed the base Public Works infrastructure improvements within the newly established public roadways, including roads, storm drainage, water, and sanitary sewer. Areas immediately north and south of downtown are characterized by older, single-family development interspersed with small-scale multi-family developments. Final 2010 4-3 •Outside of the central business district, commercial areas are concentrated along the major arterials and freeway exchanges, including Rainier Avenue, Grady Way, Sunset Boulevard, NE 4th Street, the NE 44th Street exit from Interstate 405, and SW 43rd Street. These areas are generally characterized by low intensity, auto-oriented strip commercial, but also include Renton's automall along Grady Way and several large-scale retailers. South of downtown to the city limits, the Green River Valley has developed, with manufacturing, office and warehouse uses. The south and eastern portions of the valley include some commercial uses. The Valley has experienced significant development activity in recent years, primarily comprised of a number of new warehouses, offices, and bulk retail, among other uses. Significant residential development has occurred on the uplands above the Green River Valley, downtown and East Kennydale area. These areas are primarily comprised of single-family neighborhoods, although some concentrations of multi-family and commercial uses exist. West of the downtown, residential development extends seamlessly from Renton up onto the West Hill of unincorporated King County. On the east side of the service area, residential development extends from downtown to the UGB with the denser development closer to downtown and becoming less dense as you travel east. Renton's PAA and sanitary sewer service area on the East Renton Plateau is generally characterized by large-lot single family, moderate density single-family developments, and vacant, un-platted parcels. This is an area where the City has seen significant single-family growth occur. The City anticipates continued expansion of the sewer system within the areas containing larger or grouped tracts of undeveloped or underdeveloped parcels where the zoning supports the cost of the extensions. The geography and hydrology of the Renton vicinity as well as a proactive parks acquisition program by the City of Renton combine to provide significant open spaces that constitute a passive land use. Some larger examples include lands adjacent to the Cedar River and May Creek, Gene Coulon Park on Lake Washington, the Black River Riparian Wildlife Habitat area and habitat areas of the Green River Valley. The City has had a Comprehensive Plan since 1965. The current plan, adopted in 2004 and annually amended, was developed and approved under the regulatory requirements of the Washington State Growth Management Act (GMA) and the policy framework of the King County Countywide Planning Policies. While the plan includes Transportation, Housing, Capital Facilities, Utilities, Downtown, Economic Development, and Environmental Elements, it is the policy decisions expressed in the Land Use Element that gives the plan its primary direction and cohesiveness. This LRWWMP proceeds from and supports the policies and Land Use Map of the Comprehensive Plan. Utility Element policies have been addressed in Chapter 3. To the extent that the City has jurisdiction or can require compliance, development within the service area must be consistent with Renton's Comprehensive Plan. Consistency with certain elements of the Comprehensive Plan is required as a condition of sanitary sewer service outside the city limits. The Comprehensive Plan is intended to provide the basis for all development regulations, functional plans and other City plans and programs that may in some Final 2010 4-4 way support, implement or derive from the City's land use plans. The Comprehensive Plan is a broadstatement of community goals and policies that direct the orderly.and coordinated physical development of the City. The Comprehensive Plan anticipates change and provides specific guidance for future legislative and administrative actions. The Comprehensive Plan also serves as a guide for designating land uses and infrastructure development as well as developing community services. Sewer service outside the City is currently restricted to only single family uses on existing platted lots, quasi public agencies, existing developments with confirmed health related issues to their existing on-site system, and those developments with vested sewer availability letters prior to the adoption of this current code. The purpose of this code is to allow for existing and proposed single family to connect on an existing lot, allow public uses the ability to connect, recognize uses that may have health issued that need to be addressed and recognize those developments with existing legal sewer availability letters. All new development, either residential requiring subdivision, or other type uses (Multi family, commercial, etc.) will be required to annex into the City prior to receiving sanitary sewer service. 4.3.2 City of Renton Land Use Designations The Land Use Map adopted on December 10, 2007 within the Land Use Element of the Comprehensive Plan represents the intended future pattern of land uses in the planning area as shown in Figure 4.2. The service area addressed in the LRWWMP includes most of the area within the existing city limits, the urban growth boundary and one area outside the urban growth boundary. The areas outside of the City includes 117 acres within the city limits of Tukwila, approximately 15 acres within the city limits of Kent and unincorporated areas in Renton's potential annexation area. The only area outside the urban growth boundary that Renton provides service to is the Apollo Elementary School. The district designations on the Land Use Map correspond to policies in the Land Use Element of the Comprehensive Plan and are implemented by the City's adopted Zoning Map and Zoning Code. The land use designations are described below. 4.3.2.1 RESIDENTIAL DESIGNATIONS 4.3.2.1.1 Residential Low Density Land Use Designation The designation is intended to guide development on land appropriate for a range of low intensity residential and employment where land is either constrained by sensitive areas or where the City has the opportunity to add larger-lot housing stock, at urban densities of up to 4- dwelling units per net acre (du/net acre), to its inventory.

City Limits JANUARY 2008 I__i Urban Growth Boundary Feet 1:24,000 4.3.2.1.2 Residential Single Family Land Use Designation Lands in the Residential Single Family Designation are intended to be used for quality residential detached development organized into neighborhoods at urban densities. It is intended that larger subdivision, infill development, and rehabilitation of existing housing be carefully designed to enhance and improve the quality of single-family living environments. 4.3.2.1.3 Residential Medium Density Land Use Designation • The Residential Medium Density designation is intended to create the opportunity for neighborhoods that offer a variety of lot sizes,housing, and ownership options. 4.3.2.1.4 Residential Multi-Family Land Use Designation The multi-family residential land use designation is intended to encourage a range of multi- family living environments that provide shelter for a wide variety of people in differing living situations, from all income levels, and in all stages of life. 4.3.2.2 CENTER DESIGNATIONS The City's Comprehensive Plan is based, in part, on a hierarchy of mixed-use centers, primarily comprised of residential and commercial uses. These areas are intended to be urban in land use and pedestrian in orientation. The centers vary in terms of the intensity of development and the range of intended market area for the goods and services provided. Center boundaries are intended remain relatively static. 4.3.2.2.1 Center Village Land Use Designation Center Village is characterized by areas of the City that provide an opportunity for redevelopment as close-in urban mixed-use residential and commercial areas that are pedestrian oriented. These areas are anticipated to provide medium to high-density residential development and a wide range of commercial activities serving citywide and sub-regional markets. Center Villages typically are developed within an existing suburban land use pattern where opportunities exist to modify the development pattern to accommodate more growth within the existing urban areas by providing for compact urban development, transit orientation, pedestrian circulation, and a community focal point organized around an urban village concept. 4.3.2.2.2 Urban Center Downtown Land Use Designation The Urban Center- Downtown (UC-D) is expected to redevelop as`a destination shopping area providing neighborhood, citywide, and sub-regionarservices and mixed-use residential development. UC-D residential development is expected to support urban scale multi-family projects at high densities, consistent with Urban Center policies. Projects in the UC-D are expected to incorporate mixed-uses including retail, office, residential, and service uses that support transit and further the synergism of public and private sector activities. In the surrounding neighborhoods, infill urban scale townhouse and multi-family residential Final 2010 4-7 developments are anticipated. Site planning and infrastructure will promote a pedestrian scale environment and amenities. 4.3.2.2.3 Urban Center North Land Use Designation The purpose of the Urban Center North Land Use Designation (UC-N) is to redevelop industrial land for new office, residential, and commercial uses at a sufficient scale to implement the Urban Centers criteria adopted in the Countywide Planning Policies. This portion of the Urban Center is anticipated to attract large-scale redevelopment greater than that in the UC-D, due to the large available land holdings under single ownership. In addition, this new development is expected to include a wider group of uses including remaining industrial activities, new research and development facilities, laboratories, retail integrated into pedestrian-oriented shopping districts, and a range of urban-scale mixed-use residential, office and commercial uses. The combined uses will generate significant tax income for the City and provide jobs to balance the capacity for the more than 5,000 additional households in the Urban Center. Development is expected to complement the UC-D. 4.3.2.3 EMPLOYMENT AREA DESIGNATIONS 4.3.2.3.1 Employment Area-Industrial The Employment Area-Industrial designation is intended to provide continued opportunity for manufacturing and industrial uses that create a strong employment base in the City. 4.3.2.3.2 Employment Area - Valley The purpose of the Employment Area-Valley designation is to allow the gradual transition of the Valley from traditional industrial and warehousing uses to more intensive retail service and office activities. The intent is to allow these new activities without making industrial uses non- conforming and without restricting the ability of existing businesses to expand. 4.3.2.4 COMMERCIAL DESIGNATIONS 4.3.2.4.1 Commercial Neighborhood Land Use Designation The purpose of Commercial Neighborhood designation is to provide small scale, low-intensity commercial areas located within neighborhoods primarily for the convenience of residents who live nearby. Uses should be those that provide goods and services. In addition, a limited amount of residential opportunities should be provided. 4.3.2.4.2 Commercial/Office/Residential Land Use Designation The Commercial/Office/Residential (COR) designation provides opportunities for large-scale office, commercial retail, and multi-family projects developed through a master plan and site plan process incorporation significant site amenities and/or gateway features. COR sites are typically transitions from an industrial use to a more intensive land use. The sites offer redevelopment opportunities on Lake Washington and/or the Cedar River. Final 2010 4-8 4.3.2.4.3 Commercial Corridor Land Use Designation The Commercial Corridor district is characterized by concentrated, pre-existing commercial activity, primarily in a linear urban form, that provides necessary goods and services for daily living, accessible to near-by neighborhoods, serving a sub-regional market and accommodating large volumes of traffic. Table 4.1 lists the acreage of Renton's proposed sanitary sewer service area by Renton Comprehensive Plan land use designation and with reference to the city limits. As noted above, portions of the proposed service area are within another. For those areas outside Renton's Comprehensive Planning area, land use designations are adopted by different jurisdictions. 4.3.2.5 School Designations The City of Renton serves public elementary, middle, and high schools from the Issaquah and Renton School districts in addition to private schools, Renton Technical College, and a University of Phoenix campus. These schools are spread throughout Renton and can be found within each service basin except for the May Valley Basin (Figure 4.3.). There are three schools in Renton's service area, Liberty High School, Maywood Middle School, and the Briarwood Elementary School that are not currently connected to the public sewers. All three of these schools are in the East Cedar River Basin.

School District Boundary FIGURE 4.3 Feet Sanitary Sewer Service Area 1:24,000 CITY OF RENTON LONG—RANGE WASTEWATER MANAGEMENT PLAN oN:YC''' SCHOOLS . . lPl, JANUARY 2008 4.3.3 King County Land Use The 2008 King County Comprehensive Plan directs Land use within the unincorporated portions of the study area. Policy F-249 identifies that "Public Sewer expansions shall not occur in the Rural Area and on Natural Resource Lands except where needed to address specific health and safety problems threatening structures permitted before the effective date of the County Plan or the needs of public facilities such as schools." The City does not see potential service to rural areas as a major impact to our proposed service area. The City will address the need(s) for expansion into the rural area in concurrence with King County comprehensive planning providing for the ability or need for sanitary sewer service. All of the service area in unincorporated King County is designated "urban", with the exception of the service to Apollo Elementary School just east of the urban growth areas (UGAs). UGAs are intended to develop at urban densities and with urban service levels. Under the growth management concept, these areas are expected to accommodate the majority of King County's population and employment growth. The UGB is the division line between the designated urban and rural areas that defines the eastern boundary of Renton's PAA. According to the King County Countywide Planning Policies that provide a policy framework for all comprehensive plans in King County, cities may not annex areas outside the UGB nor may they provide sewer service, except in cases of threat to public health. t Unincorporated areas of King County are divided into community planning areas, each with a community plan. These community plans were adopted as part of the 2008 King County Comprehensive Plan. Where conflicts or inconsistencies between the policies of the community plans and the County's Comprehensive Plan occur, the Comprehensive Plan takes precedence. Three community plans, Soos Creek, West Hill, and Newcastle, cover most of the unincorporated areas within the study area of this plan. 4.3.4 City of Kent Land Use City of Kent Planning.Services assures quality in the land development process by effective administration of land use codes and compliance with the GMA. Planning Services is guided by and committed to public participation, customer service, and helping to attain the highest possible quality of life for all Kent citizens. The Comprehensive Plan Land Use Map provides . the general vision for the City's growth over the next twenty years, and provides a framework for amendments to the City's official Zoning Districts Map. Approximately 15 acres of the City of Renton's sewer service area are within the City of Kent. This area is designated as single-family residential. 4.3.5 City of Tukwila Land Use During 2004, Tukwila updated its Comprehensive Plan to ensure that it meets statewide planning regulations. Key topics included reviewing policies and development codes for Final 2010 4-11 environmentally sensitive areas, as well as adopting new countywide housing and employment targets. Tukwila's Comprehensive Plan is the guiding document or"blueprint"for how Tukwila will manage future growth and development over the next twenty years. The Comprehensive Plan was adopted in 1995, with opportunities for amendments each year:Approximately 117 acres of the City of Renton's sewer service area are within the City of Tukwila'. 40 acres are within the Tukwila Urban Center that contains an intense diverse mix of use that will continue to evolve over time. The center is a regional commercial/industrial area with limited mixed use residential. The remaining area is designated as Commercial/Light Industrial. Table 4.2 displays the land use designations for those areas within Renton's service area that are outside of the City of Renton but not inside Renton's PAA.

A list and a summary of these joint use and service agreements are presented below. The full text for each of these agreements is presented in Appendix A. • Coal Creek Utility District (formerly Water District No. 107) ' — CAG-035-075, 1975 - Construction of an interceptor line from the City of Renton sewer service area through Water District No. 107 to a collection trunk operated by the Municipality of Metropolitan Seattle. — Sewer Utility Franchise, 1987 - The City of Renton granted Water District No. 107 the right to install sewer lines within the service area of Water District No. 107. — CAG-01-031, 2001 - Sewer service boundary clarification. • Final 2010 - 4-12 • City of Kent — CAG-012=83, 1983— Provides for the installation of a sanitary sewer main that is owned and operated by the City of Renton and allowing the City-of Renton to provide sewer service to the adjacent properties that are in the Kent service area. • King County — Franchise No. 14056, 2001 - Grants the City of Renton the right to construct sewer lines along County roads. • Soos Creek Water and Sewer District, formerly called Cascade Sewer District — Resolution 1234 AG-764-64, 1964 - Interceptor sewer line from the Cascade sewer system through portions of the City of Renton to the sewer system of the municipality of Metropolitan Seattle. — Agreement CAG-039-074, 1974 - Extension of the City of Renton's sewer service to certain areas within the Cascade sewer service area. — CAG-083-91, 1991 - Soos Creek Water and Sewer District to provide sewer service to certain properties within the Renton city limits. — CAG - 097-164, 1997 - Revision of the water sewer service boundary. — CAG -083-91 Addendum 1-04, 2004 - The Soos Creek Water and Sewer District may connect certain properties (described in the 1991 agreement) to the Renton Sewer System. • Skyway Water and Sewer District — CAG-03-197, 2003 - Sewer and water service boundary clarification. — CAG-06-170, 2006 - Skyway Water and Sewer District may connect a portion of their service area into the City of Renton's sewer facilities. • Cedar River Water and Sewer District — CAG-99-014, 1999 -.Water and sewer service boundary clarification. The City is surrounded by seven adjoining sewer utility entities, as previously shown in Figure 4.1. These adjacent utility entities are listed below. 4.3.6.1 Coal Creek Water and Sewer District Coal Creek Water and Sewer District (formerly King County Water District No. 107) provides sewer service in part of the May Valley Basin. The District adopted a Comprehensive Sewer Plan in 1988. They are currently preparing an update to that plan. Its plan for serving May Valley Basin includes diverting approximately 1,000 acres from the May Valley Basin to the Coal Creek Basin on an interim basis. This plan is based upon two assumptions: first, that it would be too difficult and expensive to construct a May Valley Interceptor at this time, and second, that the City of Renton's service in the southern part of the Basin is adequately provided by the Honey Creek.and Sunset Interceptors. In order to accomplish this diversion, the Final 2010 4-13 District is proposing to construct three lift stations and to complete a Coal Creek Interceptor Improvement Project. The City and Coal Creek have made boundary adjustments to remove previous service overlaps. This interlocal agreement provides for joint use of a sewer main in Lincoln Avenue for the provision of service to that area and to allow for another portion of Renton's service area to flow into Coal Creek's system. 4.3.6.2 Cedar River Water and Sewer District Cedar River Water and Sewer District (CRWSD) provides service to parts of the Lower Cedar River Basin. However, only a small fraction of the wastewater from CRWSD ultimately flows through the City of Renton's system by flowing through the Soos Creek Water and Sewer District. The majority of sewage from CRWSD flows directly into King County's Cedar River Interceptor located along the Maple Valley Highway. CRWSD's last Comprehensive Sewer Plan was adopted in 2006. Renton and CRWSD have entered into a 1999 interlocal agreement identifying the common service boundary between the two service providers. 4.3.6.3 Soos Creek Water and Sewer District Soos Creek Water and Sewer District adopted the Soos Creek Water and Sewer District Sewer Comprehensive Plan 2005(Roth HIII) in January of 2006. In 1997, the District and City entered into an interlocal agreement revising the boundary between Soos Creek and Renton that had been set by a 1991 agreement. Based upon these agreements, the City is the service provider to some areas currently outside the city and Soos creek provides service to some areas inside the city limits. A 1964 agreement provides for joint use of a sewer interceptor in the Tiffany Park Subbasin, and the 1991 agreement provides for joint use of the Springbrook Interceptor, located on S 192nd Street. The Springbrook Interceptor will provide service to the southernmost portions of the City of Renton. 4.3.6.4 City of Kent SW 43rd Street is the principal dividing line between the Cities of Renton and Kent. Renton has an agreement with Kent to serve a small area south of SW 43rd Street east of 72nd Avenue S and west of the Puget Sound Electric Railway right-of-way. The City of Kent Comprehensive Sewer Plan was adopted in 2002 (dated 2000). The Renton and Kent City limits adjoin each other. There is a small portion of the City of Kent, south of S 55th Street and east of the Valley Freeway that is in Renton's service area. There are no service area overlaps or gaps between the two entities, except for that one small area. 4.3.6.5 City of Tukwila The City of Renton serves a portion of the City of Tukwila east of the Burlington Northern Railroad and south of Longacres. Tukwila also discharges from a lift station into the King Final 2010 4-14 County Sewer System within the City of Renton along Monster Road SW. Tukwila prepared a Comprehensive Sewer Plan in 2005. This Comprehensive Sewer Plan shows the extension of sanitary sewer service by the City of Tukwila to the south of what they call Basin 10. The portion of'Basin 10' that is south of Minkler Boulevard and east of the Green River is served by Renton dating back to when this area was part of the City of Renton. 4.3.6.6 Skyway Water and Sewer District Skyway Water and Sewer District adopted a Comprehensive Plan in 2004 The Skyway sewer service area is shown in Chapter 1, Figure 1.4. The boundary between Skyway and Renton has been set by an interlocal agreement adopted in 1994. Approximately 70 percent of the District is served with sanitary sewer facilities. An area in the southern portion of the District, as well as in the service area to the south of the District, could be served by gravity to the Renton sanitary sewer system. An agreement to allow the district to route portions of this southern service area through Renton's facilities was entered into in 2006. Skyway Water and Sewer District provides sanitary sewer service to a small area of Renton along Rainier Avenue near S 117th Place and the northwest portion of the airport. Skyway sewage discharges into the King County System within the City of Renton at the north end of the Renton Airport. 4.3.6.7 King County Regional Wastewater Services Plan For more than 40 years, King County has protected water quality in the Puget Sound region by providing wastewater treatment services to King, Pierce, and Snohomish counties, including the City of Renton. To ensure the continuation of high quality wastewater treatment services in the future, King County carried out an intensive planning effort, involving numerous elected officials, representatives from local sewer agencies, organizations and individuals from around the region. The Regional Wastewater Services Plan (RWSP) resulted from these efforts, which was adopted by the King County Council in November 1999, via Ordinance 13680. The RWSP outlines a number of important projects, programs, and policies for King County to implement through 2030, and work is well underway. A summary of the major components of the RWSP includes Brightwater Treatment System, Conveyance System Improvements, Regional Infiltration and Inflow Control, Combined Sewer Overflow Control, Odor Control Program, Biosolids Recycling, and Reclaimed Water. In December 1999 as part of the RWSP, the King County Council approved the development of _ a Regional Infiltration and Inflow (I/I) Control Program. The purpose of th'e program is to reduce the risk of sanitary sewer overflows and the cost of adding capacity to facilities that convey wastewater to County treatment plants. In 2000, the County's Wastewater Treatment Division, in cooperation with the local component agencies that it serves, of which the City of Renton is one of, launched an I/I Program. The recommendations of the I/I Program represent the consensus reached by the County and local agencies throughout the 6-year program development process. Knowledge gained from flow Final 2010 4-15 monitoring, modeling, pilot projects, and a benefit-cost analysis conducted during the I/I control study served as the basis for consensus. Recommendations are presented for both I/I reduction and long-term I/I control and for program administration and policy. In addition to cost-effectively removing enough I/1 from the collection system to delay, reduce, or eliminate some otherwise needed conveyance system improvement (CSI) projects, measures must be in place to maintain I/1 reductions long-term and to prevent future increases in I/I'throughout the regional system. Long-term I/I control includes policy, administrative, financial, and technical measures that promote an ongoing program of review, maintenance, and repair of the collection and conveyance system. 4.3.6.8 Kind County Reclaimed Water Comprehensive Plan The City supports King County's planning effort and has provided King County with potential use data to facilitate the planning process. Opportunities for reclaimed water may exist in the future and the City will evaluate these opportunities and coordinate with King County as they arise. 4.3.7 City of Renton - Aquifer Protection Ordinance The City of Renton provides water service to City customers from a series of groundwater wells. In 1992, the City of Renton adopted an Aquifer Protection Ordinance to protect its water supply from being contaminated. The water facilities and aquifer protection areas are shown on Figure 4.4. The ordinance regulates land use within the aquifer recharge area in order to protect the aquifer from contamination. As part of aquifer protection the City has designated an aquifer protection area (APA), which is that area within the zone of capture for the City's aquifers and spring. The APA is divided into three zones. • Zone 1 encompasses the 1-year groundwater capture zone for the downtown wells. Regulations adopted for this zone provide the strongest protection for the area that is very close to the most important and vulnerable wells. • Zone 1 Modified encompasses the 1-year capture zones for the Maplewood, Wellfield, and Springbrook Springs, which are partially outside of the City limits. Regulations are somewhat less strict than those in Zone 1 and are intended to provide appropriate protection for important wells/springs that are deep and/or partially protected by intervening layers of relatively impermeable earth materials. — Zone 2 provides a level of protection adequate for areas that are further away from the most important sources but still within the capture zone or for deep backup wells. Zone 2 encompasses: Final 2010 4-16 „,,_,TH ' - 1 NAM • - lir ---N-..-N-1\:, la �_L :j.70117:: � , N . r / ....• 1 , I ...- .1 1 1 111 :...) \ 401%,,., /lamm l �f i11 .lLwort% r ^ �� 1 �,. •jI .:.. a 1i VIII '=. 1 `. 1�IIbh ....1 I. lien 0'i �,. -I - 1.____, i - vt / 9111111116‘:- Mt 1 \111111[ v . 1� . -�� _.._ I11�IIIIIIIIIi �� .,1 \ R&M - ' 11111a �-� _ - nl��`� �i�lierillaillaah� ��; •eoo W Y 1 , I. .rr . `� '' \ ._________ t T' Mi � na® vb. ta i , __ IWAPZEll N,,,.,,,,,,,......,,, ,..._.- .

Land use in Zone 1 is more strictly regulated than in Zone 1-Modified or Zone 2. All new development within Zones 1 must connect to the sewer system. Existing development must connect if it is within 330 feet of a sewer line. In Zone 2, all new platted single-family, multi- family and commercial development must connect to the sewer system. However, a single- family residence is required to connect only if it is within 330 feet of a sewer line. A more detailed description of the proposed aquifer protection policies can be found in Chapter 3. 4.4 DEMOGRAPHIC ANALYSIS Future sewer system requirements for the City will be based upon future growth projections within the sewer service area as described above. The planning area boundaries are determined by physical service area agreements between the City and other jurisdictions, including adjacent Cities and Sewer Utility Districts. The UGB designated by the King County Comprehensive Plan determines much of the easterly planning boundary areas. Most of the projected sewer area growth will occur to the areas east of the current City limits, including a large non-sewered area within unincorporated King County in the East Plateau service area. Population, household, and employment data was derived from the Renton Traffic Analysis Zone (RTAZ) projections from the City's Planning Department for the years 1998, 2015, and 2030. In addition to the RTAZ projections, the City Planning Department provided future planning data for areas outside the current City boundaries based on Traffic Analysis Zone (TAZ) data obtained from the Puget Sound Regional Council (PSRC). The data obtained was provided in geographic subdivisions designated as TAZ. The TAZ data consisted of both RTAZ and PSRC TAZ data. Each TAZ included projected growth of households and employment. The 2015and 2030 data include future development assumptions, such as the Boeing Redevelopment area. The RTAZ and PSRC TAZ projections meet or exceed the City's adopted Growth Management Planning Council (GMPC) population and employment targets for the City and PAA. The TAZ projections were allocated to the sewer service area using an area-allocation procedure and then further divided into the Sewer Basins by the King County Mini-Basins. The methodology for computing and assigning populations by mini-basins involved the synthesis of the TAZ data information into mini-basin populations. GIS software was utilized to compute the percentage of areas for each TAZ within each individual mini-basin. To improve the reliability and accuracy of the hydraulic model, technical judgment was applied to the computed mini- basin populations to help reduce inaccurate population assignments. This involved modifying or Final 2010 4-18 reassigning the population assignments to better match the zoning, or to obtain realistic per capita sewage flows. The actual populations assigned to the hydraulic model are summarized in the "Sanitary Sewer Model Development and Analysis Summary Report, September 2006", on file at City Hall. The Sewer Mini-Basin population projections are included in Appendix B. Population, employment and school data was assigned to the hydraulic model based on King County Sewer Mini-Basins for 2001, existing conditions. The procedure for assigning population to the hydraulic model involved using zoning information provided by the City to allocate population and employment growth projections based on the percentage of each TAZ within the Mini-Basins. A standard single-family (SF) residential household size of 2.5 persons per household (HH), and a standard multi-family (MF) residential size of 1.8 persons per HH were assumed per the City Planning Department Staff. The 2030 data provided by the City is considered to be ultimate built-out population by City Planning Staff. For hydraulic modeling purposes, all populations assigned to the model were increased by an additional 25 percent to establish the, Ultimate (Saturation) Scenario. School populations(combined students and staff) were assigned to the appropriate manholes within the model. Existing staff and student populations were obtained from the Renton School District. School populations for the ultimate model were assumed to grow by the same overall percentage as the combined residential population within the corresponding mini-basin. The planning projections for each of basin are presented in Table 4.3. 4.5 ANALYSIS AND DESIGN CRITERIA This section presents the design criteria for sanitary sewage collection system analysis and design. Analysis is necessary to determine the adequacy of the existing system and to identify needs for future facilities. The analysis and design criteria are based on "Criteria For Sewerage Works Design" prepared by the Washington State Department of Ecology, King County Department of Natural Resources - Wastewater Division, the City of Renton Standards, actual water usage records, and other accepted engineering criteria and standards for sanitary sewer design and construction. 4.5.1 Wastewater Flow Rates - Definition Wastewater in the service area is generated by the population and by non-residential users within it. The Renton Comprehensive Land Use Plan identifies twelve, separate land use categories. For sanitary sewer planning purposes, these twelve categories were used to determine wastewater flow rates for the hydraulic computer model. The twelve land use categories are listed in the Land Use section of this Chapter. Twelve saturation land use populations were determined by calculating the areas of each designated land use category. This was accomplished by assigning land use designations to all Final 2010 - 4-19 parcels within a land use boundary on a computer base map that was used for producing the figures for this plan. Saturation was defined as the point at which development is complete within a land use designation. 4.5.2 Wastewater Flow Criteria Wastewater flows can be divided into four major components, which are 1) domestic wastes, 2) industrial wastewater, 3) inflow, and 4) infiltration. The wastewater flow criteria used for each or these four components is presented in Table 4.4. 4.5.2.1 Domestic Wastewater Domestic wastewater flows are essentially equal to wintertime water consumption and are typically established on a per capita basis. The average domestic wastewater flow used for analysis and design of the sanitary sewer system is 100 gallons per day per person. 4.5.2.2 Commercial/Industrial Wastewater Commercial and industrial wastewater is defined as the wastewater generated from a specific commercial or industrial operation. Commercial and industrial wastewater does not include waste generated by employees of the industry, which is considered domestic waste and excluded from this category. 4.5.2.3 Inflow and Infiltration Inflow refers to direct flows of stormwater into sanitary sewer systems through hookups from stormwater collection.facilities and illegal connections. Stormwater inflow is due mainly to unauthorized connections to the sanitary sewer system. The enforcement of regulations banning the illegal connections to the sanitary sewer system along with continued efforts to identify and correct previously unauthorized connections minimize stormwater inflow. Infiltration is the entrance of groundwater into the sanitary sewer system through cracks, pores, breaks, and defective joints in the sewer-piping network. Additional infiltration also results from the entrance of storm water through manhole covers. The quantity of water that may infiltrate into a sanitary sewer system depends upon many variables, such as the age ofthe system, materials used in construction, and the service area's hydrology, soils and groundwater level. However, the design of the sewer system, including mains, laterals, and individual connections, along with inspection during construction, will have substantial impact on the quantity of infiltration.

Final 2010 4-22 Due to improvements in construction materials and practices, systems installed after 1960 generally show a decrease in the quantity of groundwater infiltration. The use of non-porous piping materials and rubber-gasket type joints will help reduce infiltration and will improve the condition and life of the sanitary sewer system. Renton participated with King County in a regional I/I study. One result of the study was recognition that 1,100 gallons per acre per day (gpad) was not a realistic number. The group determined that a value of 1,500 gpad more accurately represented a minimum value for new systems. I/I values for existing portions of Renton's system will utilize I/I values established as part of the regional study for each mini basin analyzed. The areas for each mini-basin for 2001 and ultimate conditions were estimated using GIS Analysis during the Demographic analysis. A summary of the 2001 and Ultimate area served in acres is summarized in Table 4.5 for each of the basins: Table 4.5 Developed Basin Areas Long Range Wastewater Management Plan City of Renton Area (acres) Basin 2001 Ultimate Black River Basin 2,773 • 2,876 Downtown Basin 1,654 1,654 East Cedar River Basin 0 2,105 East Lake Washington Basin 2,539 3,104 May Valley Basin 130 130 West Cedar River Basin 1,752 2,142 Total 8,847 12,010 Note: Areas represent the total developable areas and thus the total presented here is less than the total area of the service area as described in Table 4.1. 4.5.3 Sanitary Sewer Design Criteria All sewer lines within the City of Renton shall be designed in accordance with good engineering practice by a professional engineer with minimum design criteria presented in Chapter Cl of the "Criteria for Sewerage Works Design," prepared by the State of Washington Department of Ecology, November 2007, or as superseded by subsequent updates. This chapter includes standards and guidelines for design considerations (minimum pipe sizes, pipe slopes and wastewater velocities), maintenance considerations, estimating wastewater flow rates, manhole locations, leak testing and separation from water pipelines. These criteria have been established to ensure that the sanitary sewers convey the sewage and protect the public health and the environment. The sewer lines shall also conform to the latest City of Renton Standards Final 2010 4-23 and Specifications. Detailed standards are included in Title 4, Chapter 6 of the City Code. Requirements relating to design are listed below. 4.5.3.1 Design Loading for Sanitary Sewer Facilities Sanitary sewer system flows are composed of residential, institutional, commercial, and industrial sewage, along with infiltration and stormwater inflow. Sanitary sewer systems must be capable of conveying the ultimate peak flows of these wastewater sources. No overflows shall be permitted. 4.5.3.2 Design Period The design period is the length of time that a given facility will provide safe, adequate and reliable service. The period selected for a given facility is based on its economic life, which is determined by the following factors: the structural integrity of the facility, rate of degradation, cost of replacing the facility, cost of increasing the capacity of the facility, and the projected population growth rate serviced by the facility. Collection and interceptor sewers are designed for the ultimate development of the contributing area. The life expectancy for new sanitary sewers, using current design practices, is in excess of eighty years. 4.5.3.3 Design of Sanitary Sewer Facilities Allowable sewer pipe shall be ductile iron, high-density polyethylene (HDPE), polyvinyl chloride (PVC), or concrete. For normal depth, PVC is generally preferable, because it has longer laying lengths, which results in fewer joints, reducing the potential for infiltration. Gravity sewers are sized to provide capacity for peak, wet-weather flows. The smallest diameter sewer allowed is 8-inches, except for limited conditions. All sewers will be laid on a grade to produce a mean velocity when flowing half-full of at least two feet per second. Manholes will be at least 48-inches in diameter and will be spaced at intervals not to exceed 400 feet on sewer lines 15-inches in diameter or less, and 500 feet on sewer lines 18-inches in diameter or larger. The design parameters are summarized in Table 4.6. 4.5.3.4 Roughness Coefficient The Manning equation shall be used to design and analyze wastewater flow characteristics of the sanitary sewers. The Manning roughness constant [n] shall vary depending on the pipe material. For sewer modeling, a Manning's equivalent of 0.013 will be used. Typical values are summarized in Table 4.6. 4.5.3.5 Reference Datum The North American Vertical Datum (NAVD) 1988 is the standard datum used within the City of Renton for design and construction of sanitary sewer facilities. Final 2010 . 4-24 4.5.3.6 Separation between Sanitary and Other Facilities The Department of Ecology requires a ten-foot separation of water and sewer facilities for health reasons. Sanitary and storm sewer facilities shall have basic separation requirements for construction purposes. A minimum horizontal separation of five feet between sanitary and other facilities shall be maintained. Wherever possible, a horizontal separation of seven feet is desirable. These distances are measured edge to edge. 4.5.3.7 Hydraulic Analysis The hydraulics of the City of Renton's sewer service area is modeled with the MOUSE software program by the Danish Hydraulic Institute. The model was calibrated to flow data measured between 2001 and 2002 and then updated to reflect the system in 2005. The City currently maintains and updates the model as needed. All new developments, with the exception of developments involving less than five single-family residences, may require a hydraulic analysis. The sanitary sewer system hydraulic analyses will be performed using the City's hydraulic computer model. The developer may be responsible for paying the cost of the analysis of the sanitary sewer system. If the analysis concludes improvements need to be made, the developer and the City may need to negotiate cost allocation. 4.5.4 Lift Station Design Criteria Sewage lift stations within the City of Renton shall be designed in accordance with good engineering practice by a professional engineer using the minimum design criteria presented in Chapter C2 of the "Criteria For Sewerage Works Design," prepared by the Washington State Department of Ecology, November 2007, or any subsequent updates, and shall conform to the latest City of Renton standards and specifications. Detailed standards are included in Title 4, Chapter 6 of the City Code. Requirements relating to the design are listed below. 4.5.4.1 Design Loading for Lift Stations Lift stations shall be designed to handle the peak, wet-weather flow from the contributing area. All lift stations, except for private stations for a single family home, shall have a minimum of two pump units, each with the capacity to handle the expected maximum flow. 4.5.4.2 Design Period The design period for lift stations shall take into consideration long-term needs, replacement or expansion difficulties, service area growth rate and useful life. A lift station should have a minimum design period of twenty years for the facility and ten years for mechanical and electrical equipment. Consideration should be given to longer design periods for lift stations that are expected to serve an indefinite-life. Consideration must also be given to the ability of the consumers to pay for the facilities.

If wide variations in wastewater flow rates are expected for the lift station, then consideration should be given to the use of three or more pumping units. If three pumps are used, two of there must have the capacity to convey peak wastewater flow rates. Each pump shall be capable of passing spheres of at least 3 inches in diameter. Final 2010 4-26 Each lift station will be provided with an on-site power backup. The City may allow the use of portable power backup for smaller stations. A lift station designed for portable power backup shall be provided with sufficient wet-well storage to allow adequate time for maintenance personnel to transport, setup, and provide the necessary backup, during a power outage. Wet- well storage will be designed on the basis of the peak, wet-weather flow. Force mains shall be sized to maintain a minimum velocity of 2 feet per second. The force main shall have a maximum velocity of 10 feet per second when all pumps are operating together. Regardless of these velocity criteria, minimum size shall be three inches in diameter. A minimum of four inches in diameter is preferable. Each lift station to be owned by the City shall have control and telemetry systems that are consistent and compatible with the current City system. 4.5.5 Elimination of Lift Station Facilities Lift station facilities are typically eliminated through the development of the gravity sewer system. Highest priority should be given to elimination of lift station facilities because of their high degree of vulnerability and high operation and maintenance costs. These considerations include environmental risks, life-cycle costs, lift station impacts on downstream sanitary sewer facilities, vulnerability to vandalism, and lift station accessibility. Final 2010 4-27 Chapter 5 SYSTEM ANALYSIS AND RESULTS 5.1 INTRODUCTION This chapter presents a detailed analysis of all aspects of the existing system and their recommended improvements. It includes the hydraulic analysis performed using the new hydraulic model, the structural analysis of the wastewater system components and a summary of system-wide concerns. The results are summarized at the end of the chapter for each sewer basin and within the entire system (system-wide). Capacity problems are a concern in any sewer system. Capacity problems would be a result of inadequate pipe sizes or slopes. These problems can be either concerns about current lack of capacity in the sewer system or concerns about available capacity for future development. A hydraulic analysis has been performed on the Renton sewer system. This analysis did not show capacity problems in the current system. Capacity problems do occur throughout the system in various degrees at saturation build out. As the City implements more water conservation programs, there may be a negative impact on the operation of a sewer system. Reduction of the liquid component of wastewater could cause problems in moving solids through the lines. Problems moving solids could impact the operation of the system, increase the potential of sanitary sewer overflows and will increase the need for flushing. Much of the existing sanitary sewer system was installed during the 1940s and 1950s as a federal program to provide housing for workers at the Renton Boeing Plant. Prior to this boom, the.City also had significant sewer installations in the 1920s and 1930s for the Central Business District. These sewers have reached the end of their useful life and are scheduled in the near future for replacement. This LRWWMP recommends evaluating and prioritizing the replacement of these aging sanitary sewers. Infiltration and inflow (I/I) occur in all sanitary sewer systems. Infiltration is defined as water entering the sanitary sewer system through pipes, joint connections, manhole covers, and walls. Inflow is defined as water discharged to the sanitary sewer system through connections to roof drains, yard drains, foundation drains, and cross connections with storm sewers and combined sewers. The combination of both I/I often is a major portion of the total wastewater flow, which must be carried by the sanitary sewer system. I/I problems in an existing sanitary sewer system can be studied to determine their effect. Finding and correcting I/I sources can be challenging, as determining source can be evasive. Renton is participating with King County on its program to gain knowledge and experience to guide us in determining ways to deal with this issue. Combined sewers are designed to carry both stormwater and wastewater within a single system. Current codes in the City of Renton do not allow combined sewers because it Final 2010 5-1 causes stormwater, which is relatively clean, to be treated along with wastewater. Combined sewer systems within the City have been replaced with separate sanitary and storm sewer. systems. 5.1.1 .Hydraulic Analysis 5.1.1.1 . Model Development An updated hydraulic computer model of the City's sewer system was completed in 2006. The purpose of this model was 1) to evaluate the existing sanitary sewer system and determine areas of capacity constraint, and 2) to provide a tool for planning future improvements. The hydraulic computer model was developed using the MOUSE software program by the Danish Hydraulic Institute (DHI). The primary reason the City chose to use MOUSE was that King County used MOUSE for the Regional I/1 study. It was anticipated that having the same tools available as the County would allow the City to take advantage of the County's data and provide a common basis for discussion of projects, agreements, and issues. The City will also use MOUSE as a regulatory tool to comply with potential Capacity Management Operation and Maintenance (CMOM) regulations, an electronic data base, a capital improvement planning tool, a future development tool and to assist with operational optimization challenges. Three basic kinds of data were needed for the computer model: physical data, domestic wastewater flow data, and I/1 data. The physical basis for the MOUSE model was primarily the City's electronic database of sewer system that included data through the end of year 2001 to create a "2001 model." The physical system data include manholes, pipes and lift stations. The majority of the City's sewer system, as it existed, was incorporated into the hydraulic model. Clean-outs, dead-end portions of the system with missing/errant information, and some portions of private system were not included. As a result, the model of the sanitary system does not include 100 percent of the sanitary sewer system. The majority of the missing data is from the upper reaches of the system and was not included as a high priority for the hydraulic analysis. Other regional data was also obtained from King County. The 2001 model was developed simply to establish calibration parameters and calibrate the model using King County's flow monitoring data associated with three separate storm events during the 2000 to 2002 calibration period. This model was then used to create the "Ultimate" physical model. The "Ultimate" physical model includes all the significant project and modifications to the City's sewer system through the end of 2005. The model also includes other future improvements to simulate service to the future sewer service area. The calibrated I/1 parameters used for the 2001 model were applied to the Ultimate model, except that I/I was globally increased per the King County's methodology, which assumes a 7.0 percent increase per decade to a maximum degradation of 28.0 percent for Ultimate Final 2010 5-2 conditions. For system improvements constructed mid-2002 or later, a global I/I assignment of 1,500 gallons per acre per day was assumed. Domestic wastewater flow rates were developed differently for the two models. For the 2001 model, dry weather flows generated during the flow monitoring that occurred in 2000/2001 were used. The 2030, assumed to be Ultimate conditions, future sewer system population assignments were based upon future growth projections within the.established sewer service area. These were derived from the Renton Traffic Analysis Zone (RTAZ) projections. In addition to the RTAZ projections, the city provided future planning data for areas outside the current City boundaries based upon Traffic Analysis Zone data obtained from the Puget Sound Regional,Council (PSRC), which was incorporated into the projections. To account for a saturation condition, a 25 percent safety factor was added to assure we provide sufficient capacity as existing interceptors are replaced. Using the tools within the hydraulic model, the flows are distributed appropriately within the system. Pump station flow was determined through a combination of telemetry data for stations with meters and engineered design flows for those without meters and then appropriately distributed by the model. This model is used by the City to evaluate changes to the existing system or additions to the system during the design phase of each sewer project. However, to increase the reliability of the model output, the City is continuously updating the physical data for the sewer system to increase accuracy in the model. The City is also working with King County as part of the ongoing I/I Program and will utilize the flow information gathered by King County. The model will need to be updated as the sewer system is expanded, flow monitoring data collected, physical system data collected by survey or field inspection and as software is updated. 5.1.1.2 Model Analysis The peak flow and capacity analysis utilized a simulated rainfall event from January 9, 1990 for the 2001 model, a peak flow analysis. It was intended to generate a minimum of 20-year design flows within the system. The selection of this storm event was based upon 60 years of rainfall data obtained from the King County model. Of all the ranked storm events during the 60-year period, the January 9, 1990 storm most consistently is ranked in within the top three events in each of the modeling basins. This analysis allowed the City the ability to determine near term capacity issues that are addressed in the first ten to fifteen years of the proposed Capital Improvement Program. It also allowed a "truth-test" to the model based upon operational and maintenance knowledge of the existing system versus results from the model. . The Ultimate Model peak flow and capacity analysis used a peak 20-year event. The County identified nine different storm events that generated the 20-year peak flows for Renton's model Basins. Rather than run the model nine separate times to capture 20-year Final 2010 5-3 events, four separate storm events were selected to generate the 20-year or 30-year peak flows in each of basins. This Ultimate Analysis evaluated peak flow inputs to calculate this flow as saturation. This analysis shaped the potential capital needs within the last 5-10 years of the Capital Improvement Program. Table 5.1 summarizes the ultimate peak flow at the outlet from each mini-basin and the corresponding storm events. It also lists the peak flow rates from the 2001 Model analysis for comparison. One component of the peak flow rates is I/I. For additional discussion of I/I see Section 5.2.7. For more complete information on the development and results of the sewer model, see "City of Renton Sanitary Sewer Model Development and Analysis Summary Report-Roth Hill September 2006."

The Sanitary Sewer Maintenance Division owns and operates its own sewer video inspection equipment. The video equipment is programmed to be used daily. Video inspections have been ` organized and documented utilizing the present system and its predecessors since 1988. - The video inspection averages approximately 980 feet per day. The inspection process requires hydraulic jet cleaning of the sanitary sewer section prior to the video inspection. After completion of the video inspection, roots are cut and cracks are sealed, if necessary, before proceeding to the next section. The video inspection equipment requires two people to operate. If traffic control is necessary, two additional people are required. At the current rate, it will take four to five years to video inspect all existing sanitary sewers. It is recommended that sewers near the end of their useful life be video inspected every five years. All other sewers should be inspected every ten years. The City utilizes an off the shelf television inspection program and equipment that allows the crews to inspect the facilities, record video images, and create a database of the information obtained through the inspections. This data is stored on the computer in,the inspection truck and backed up onto a computer in the office and onto DVDs. The following is a discussion of specific problems that are associated with the gravity sanitary sewer system in the City of Renton. 5.1.2.1 Aging Sewers Many of the gravity sewers within Earlington, Renton Hill, the Central Business District, and the Highlands were constructed in the 1930s and 1940s. Some as a result of housing constructed for the Boeing plant in Renton during World War II. Many of these sewers have reached their design life expectancy (beyond 50 years). As these sewers approach the end Final 2010 5-6 of their useful life, increased maintenance and structural inspections should occur to locate ' and prevent pipe failures. The 1998 Long-Range Wastewater Management.Plan identified some of the older sewers and established a capital improvement program to replace and upgrade them:Primarily focused in the Highlands and Earlington Area, these replacements have been delayed, as the utility has had to focus its resources toward capacity improvement over the past eight years. 5.1.2.2 Reverse Pipes and Sags A major maintenance problem associated with sanitary sewers that are laid with a reverse slope or have sag due to improper construction or differential settlement is that they require periodic cleaning to remove debris. There are approximately 89 such sewer sections within the City. 5.1.2.3 Root Problems Tree roots cause problems in sanitary sewers by penetrating and cracking sanitary sewer pipe joints to feed on the wastewater. Tree roots can also create blockages, resulting in backed-up sewers. The City has approximately 120 sections of pipe of various lengths which require routine root cutting maintenance to prevent wastewater backups and reduce pipe damage. The Wastewater Maintenance Section has met its goal of keeping the City's I mains from being blocked by root intrusion. 5.1.2.4 Odor Issues Odor issues within the City sewer system are rare, most often associated with the operation of lift stations. Issues are typically resolved through adjustment of maintenance procedures or by providing an odor mitigation process. 5.1.3 Lift Station Analysis This LRWWMP evaluated lift stations against the standards and guidelines for construction of sewage lift stations that are detailed in Chapter C2 of the "Criteria for Sewage Works Design" manual prepared by the Washington State Department of Ecology (November 2007 or later). The design standards and guidelines for lift station location, pump sizing and selection, wet well sizing criteria, alarm system, emergency response criteria, force main criteria, lighting and ventilation are summarized in Chapter 4. These standards and guidelines have been established to ensure protection of the environment and property through design and operation of reliable sewage lift stations. Each sewage lift station was inspected for safety and accessibility, and.operation and maintenance manuals for each were reviewed at the City Shops. With few exceptions, these lift stations have no major inadequacies in terms of safety or reliability. Final 2010 5-7 5.2 SYSTEM-WIDE CONCERNS 5.2.1 King County-Interceptor Surcharge During peak flows,King County will use its interceptors for storage of wastewater and for controlling flows in the South Treatment Plant. This may result in surcharging of the King County interceptors. King County reserves the right to surcharge its interceptors to an elevation of 25 feet. King County has never reached this extreme; however, the City has experienced sewer surcharge'problems in the low-lying areas. As a result of King County's surcharging, it is possible that additional wastewater could overflow in low-lying areas through manhole covers and side sewer connections. King County, as part of their regional conveyance system needs report, dated December 2005, identified long-term capacity concerns within portions of the east-side interceptor in Renton. The Report identifies capacity projects to alleviate the capacity restraints. These projects are located upstream and outside of Renton's service area. The City has not designed facilities to accommodate a sewer surcharge to an elevation of 25 feet. The City's current position is that King County is responsible for providing adequate capacity within its interceptors and wastewater treatment facilities. In addition, the City considers King County to be responsible for proper effluent disposal. During the preparation of the Comprehensive Sewer Plan, no specific analysis was made of the effect of King County's surcharging on the City's sewer system. King County should continue to study and identify areas of potential risk and alternatives to mitigate this problem. King County has increased the influent and effluent capacity at South Plant and has installed parallel interceptor facilities. This has significantly reduced the chance of surcharging but does not eliminate the problem. 5.2.2 Adjacent Utility Systems For purposes of this LRWWMP, all of the comprehensive plans for the adjacent utility systems described in Chapter 4 were examined. The hydraulic analysis utilized the projected Ultimate Peak 20-year design flows, as computed by the county. These flows were obtained from the County and assigned as constant inflow conditions. This conservative assumption contributed to surcharging and capacity issues in portions of the system. The City of Renton has several agreements with adjacent utilities that allow joint use of facilities within the City. It is important that these adjacent utilities are restricted to the volume of wastewater discharged to the joint use facilities. If capacity problems become. evident, through visual inspection or flow measurements, then the City and the adjacent utility should work together to investigate the potential sources, both within the City's service area and within the adjacent utility, to correct the problem. Final 2010 5-8 5.2.3 Hazard Mitigation Plan The City of Renton has developed a local Hazard Mitigation Plan in 2003 that includes actions taken to reduce or eliminate long-term risk to people and property from the affect of both natural and man-made hazards. The City is subject to a number of natural and man- made hazards that could affect the city, such as earthquakes, flooding, landslides, winter/wind storms, coal mine hazards, hazardous materials release, and terrorism/civil disturbance: The sanitary sewer system may be vulnerable to a variety of the identified hazards. The City identified goals that will guide the implementation of the Hazard Mitigation Plan and determine how to best minimize impacts of disasters. The goals include: 1. To protect aquifers used by the City and the City water supply system from contamination by hazardous materials and other hazard effects. 2. Minimize public and private losses due to flood conditions in specific areas. 3. Minimize damage due to natural hazards. 4. Minimize impacts on critical habitats and wetlands from natural or man-made disasters. 5. Minimize the impacts of technological or man-made disasters on the City. 6. Enhance the City's capability for gathering, organizing, and displaying spatial data regarding hazards, vulnerabilities, critical facilities, and vital statistics. The City has identified several hazard mitigation projects that would benefit the city. The committee focused on measures in the areas of aquifer protection, flooding, earthquakes/landslides, and technological hazards. The measures specifically associated with the sanitary sewer system include: • Implementation and maintenance of an Aquifer Protection Program. • Re-enforce utility infrastructure and connections. • Develop objective criteria and conduct seismic preparedness and retrofit of critical facilities. • Implement slope stabilization measures in steep/unstable areas. 5.2.4 Septic Systems There are still a small percentage of developed properties within the Renton City Limits that are served by private septic systems. In addition, the developed properties within the sewer service area but outside of the city limits are primarily served by private septic systems. There are several areas that have been identified by the Seattle-King County Department of Public Health as being areas of concern. These areas are typically identified as having Final 2010 5-9 smaller lots, poor soils, older septic systems, and high or perched water tables. These ( areas, are: • The majority of the area between the Renton City Limits and Skyway Water and Sewer District and north of Martin Luther King Way. The City has installed sewers in 80th Avenue S and S 130th Street. This is a neighborhood that has had septic tank problems and talked to the City about sewer service. • The Puget Colony Homes Plat off 142nd Avenue SE (at approximately SE 134th Street). A proposed development between NE 2nd Street, SE 2nd Street, Jericho Avenue, and 142nd Ave SE will construct sanitary sewers in the vicinity of the Puget Colony Homes Plat, making it available for extension into the plat when requested by Local Improvement District (LID) or by small development extensions to existing vacant parcels. • The White Fence Ranch Plat off SE 128th Street (at approximately 156th Avenue SE). The completion of Maureen Highlands Plat has brought sewers to the west boundary of White Fence Ranch. Some minor development of existing vacant lots is providing construction of sewers in the vicinity of SE 124th Street and 155th Avenue SE. A capital project, scheduled for construction in 2008, is expected to have sanitary sewers available to this neighborhood by 2009. • The Gerber's Addition Plat off 148th Avenue SE (at approximately SE 124th Street). Sewer mains have been installed in Nile Avenue NE (148th Avenue SE) and are available for extension by LID into the Gerber's Addition Plat. • Sierra Heights Divisions 3 and 4 vicinity of 126th Avenue SE and SE 103rd Street. The Sierra Heights area has sanitary sewers directly adjacent to the area and a LID for extension would be immediately available if the property owners or Seattle King County Department of Public Health chose to initiate one. The Seattle-King County Department of Public Health has expressed concern about the lack of sewer service to schools on the east Renton Plateau. Renton is working with the Issaquah School District toward providing sewer service to the schools. The three Issaquah Schools as shown on Figure 4.1 (Chapter 4) are: 1. Briarwood Elementary School 2. Liberty High School 3. Maywood Middle School The Seattle-King County Department of Public Health also identified the Lake Kathleen area, the Lake McDonald area, the Maple Hills Estates area, a couple of mobile home parks along Renton - Issaquah Road, and a small neighborhood along SE 121st Place (off 176th Avenue SE) as places where there are also problems with septic systems. These areas are all outside of the Urban Growth Boundary (UGB). At some time in the future, the i Final 2010 5-10 • Renton Wastewater Utility, in coordination with King County, may have to take action to provide relief to these areas outside the UGB. Potential solutions may include tight—lining sewers to these areas or the development of community drainfields where feasible. 5.2.5 - Wastewater Quality The quality of wastewater transported in the Renton sanitary sewer system varies considerably depending on the wastewater source, detention time within the sanitary sewer system and the volume of I/I. The quality of domestic wastewater varies and is a direct result of the type of water used within the home. Some domestic sewage can be considered stronger than others can. One household appliance, the garbage disposal, can greatly impact the quality of wastewater. Most new home construction incorporates garbage disposal in its design. Use of these garbage disposals increases both suspended solids and the biochemical oxygen demand (BOD), two common results tested for when measuring contaminant.concentrations. The total volume of industrial waste produced within the City of Renton is small compared with the volume of domestic wastewater. However, an industrial or commercial development can have a considerable impact on the sanitary sewer collection system immediately downstream of the facility. Industrial waste can contain high concentrations of chemicals that can make the waste highly corrosive or toxic. If discharge of an industrial waste to the sanitary sewer system creates problems, then pretreatment of the industrial waste should be considered. Several federal, state, and local regulations govern the pretreatment of industrial waste. Several industries within the City have obtained National Pollution Discharge Elimination Systems (NPDES) permits. The most recent list of industrial discharges is provided in Table 5.2. The King County Industrial Waste Program is a state delegated authority to implement the Federal Pretreatment Program and handles the industrial waste for the City of Renton. This program administers the waste discharge permits, inspections, enforcements, compliance and collection of surcharge monitoring fees. The program also works with business to help them implement pollution prevention practices. The industrial dischargers submit monthly self monitoring reports to the King County Industrial Waste Program to confirm compliance with their NPDES permits. Additionally, King County conducts twice yearly monitoring of the discharges. Within the past five years there have been six NPDES permit violations (Table 5.2), two of the violations were for failure to report and the remaining four violations were for exceedence of Zinc limits. 5.2.6 Wastewater Quality Analysis and Recommendations A major problem associated with wastewater quality is the generation of hydrogen sulfide that occurs during wastewater transport from its source to the point of treatment. The hydrogen sulfide found in wastewater results from the anaerobic bacterial reduction of the sulfate ions that are present. Hydrogen sulfide poses three serious problems: it is highly Final 2010 5-11 corrosive, has an obnoxious odor, and as a gas is toxic to humans and has been known to cause death to sewer maintenance workers. The production of hydrogen sulfide is directly related to the BOD of the wastewater. Wastewater exhibiting a high BOD will tend to ' generate more hydrogen sulfide than wastewater exhibiting a lower BOD. Hydrogen sulfide is very corrosive to both sewers and pumping facilities. Hydrogen sulfide released from the wastewater will tend to dissolve on condensation within the crown of a sanitary sewer. The hydrogen sulfide retained in the condensation is converted to sulfuric acid through oxidation by aerobic bacteria. This sulfuric acid will react with the cement bonding material within concrete pipes, or iron within steel pipes, and can corrode a pipe to the point of structural failure. Sanitary sewer pipes are most susceptible to this type of corrosion in their crowns because that is where most condensation occurs. Aeration, periodic cleaning, and use of non-corrosive pipe materials can control effects of hydrogen sulfide. If excessive hydrogen sulfide production is evident at a lift station, aeration of the wet well should be considered to reduce the hydrogen sulfide in the wastewater and reduce the effects of anaerobic bacteria that produce the hydrogen sulfide. Periodic cleaning of the sanitary sewers will also remove the biological slime that forms on the pipe walls and produces the hydrogen sulfide. The most effective method of mitigating corrosion by hydrogen sulfide is through the use of non-corrosive pipe materials, such as polyvinyl chloride (PVC), or high-density polyethylene (HDPE). Existing pipes experiencing severe corrosion can be rehabilitated through the use of various slip form liners or fiberglass resin liners. In order to control the generation of hydrogen sulfide, the City's maintenance crews routinely flush and clean sewer pipes with inadequate slopes. In addition, all pipes are cleaned before video inspection is performed. Both of these tasks reduce biological growth on the walls of the sewer pipes and reduce the hydrogen sulfide generation potential. Excessive Ill will tend to lower the BOD. This will tend to reduce the production of hydrogen sulfide and the concentration of contaminants in the wastewater. As the City works to reduce Ill, there may be more impact by contaminants and hydrogen sulfide. The City may have to increase efforts to reduce hydrogen sulfide and be more aware of potential. contaminants.

Data provided by King County in September of 2008. Final 2010 5-13 5.2.7 Infiltration and Inflow A portion of the flow in any sanitary sewer system may consist of I/I. Infiltration is attributed to groundwater entering into.the sewer system and inflow is storm water flowing directly into the system as the result of a "storm incident" or illegal connections such as a direct connection of storm sewers, downspouts, or foundation drains. Infiltration can enter the system through leaking pipe joints, structural cracks, or other physical defects. Elimination of storm inflow from the system is difficult due to conflicting concerns. Sealing manhole lids and maintaining the water tightness of the lids decreases inflow, but gas, particularly hydrogen sulfide and methane, can collect in the sealed manholes. The City attempts to minimize vent holes for the system, but inflow cannot be prevented completely. During the design and construction of new main,extensions, the City utilizes manhole liners and coatings as well as sealed manhole covers in wet areas. The City also performs video inspections during the wet season on all new gravity sewers to check for leaks. In December 1999 as part of the Regional Wastewater Services Plan (RWSP), the King County Council approved the development of a Regional I/I Control Program. The purpose of the program is to reduce the risk of sanitary sewer overflows and the cost of adding capacity to facilities that convey wastewater to County treatment plants. The County installed over 800 flow meters to measure flows throughout the County. The flow meters monitor depth of flow and velocity. Early flow monitoring data between late 2000 and early ( 2001 were considered unrepresentative because of drought conditions that lowered the groundwater table and therefore reduced I/I to the system. Consequently, King County performed additional flow monitoring from late 2001 to early 2002. This effort proved more productive as data from several storms was captured. Rainfall in the region was also monitored by King County. The system (CALAMAR) used a combination of 73 rain gauges throughout the region, as well as the National Weather Service radar, to generate rainfall quantities to an accuracy of plus or minus 10 percent. In 2000, the County's Wastewater Treatment Division, in cooperation with the local component agencies that it serves launched an I/I Program. Ten pilot projects were selected to evaluate the effectiveness of various sewer rehabilitation technologies in reducing I/I in local agency collection systems. The completion of the ten pilot projects in January 2004 marked a major milestone in the King County study. The projects demonstrated that I/I could be effectively reduced, depending on the location and method of rehabilitation. The results of the pilot projects, along with other information, were used to prepare a long-term regional plan for reducing I/I in local agency systems. Old and aging sewers contribute to excessive I/I into the sanitary sewer system. In conjunction with King County's program for reducing I/I, the City identified, through model analysis, areas of concern for investigation, additional metering, and replacement or rehabilitation of the sewers. There are certain portions of the sanitary sewer system that are ( known as having I/I in excess of the 1,500 GPAD identified as the acceptable amount as Final 2010 5-14 determined through the joint planning effort between King County and the component agencies. The City works to reduce the I/I in these portions of the system through its mainline and lateral replacement program. If these systems are replaced, I/I will be reduced and King County's requirements will be met. If a system is not scheduled for replacement or a replacement is delayed, the City may have to perform interim rehabilitation to reduce I/I if required for capacity needs. In addition, the City will continue to follow King County's work on its I/I program. The additional data produced through the current effort occurring through 2012 will be used by the City in determining feasibility of using I/1 improvements in lieu of upsizing sewer systems where capacity restraints have been identified. The sewer model has also identified portions of the sewer system that have 1/I or capacity problems that have not manifested themselves with physical signs. The City needs to perform additional metering and investigation of these areas to determine the accuracy of the model, update the model data, and determine the level of need for replacement or rehabilitation. The City will initiate an I/I Metering, Investigation, and Rehabilitation and Replacement of Sanitary Sewer Mains for Control program. The program will perform additional metering and investigation of the sewer system. 5.3 WASTEWATER COLLECTION BASINS The following section summarizes the deficiencies within each of the City's six wastewater collection basins based on the above hydraulic, structural, lift station, and system-wide analysis. The summary of the analysis describes the capacity and replacement deficiencies in addition to the lift station recommendations for each basin. The City's six sewer basins, as described in Chapter 2, are located on Figure 5.1. 5.3.1 West Cedar River Basin The West Cedar River Basin includes the eastern portion of the City of Renton bordering the Cedar River. This basin consists of primarily single-family and multi-family developments with some commercial and light industrial land uses. By ultimate buildout, it is estimated that the City will serve approximately 2,142 acres within this basin. This basin includes modeling basins CEDAR02 and RNT065. 5.3.1.1 Model Basin CEDAR02A Model Basin CEDAR02A is located on the north side of Cedar River. This model basin includes primarily single-family and multi-family developments. This model basin includes the Cottonwood Lift Station. This model basin currently takes significant flows from the East Cedar River Basin via the East Renton Lift Station.

Upstream from this issue, the model also identifies potential severe capacity issues between manholes 5308-341 and 5317-185 (with one manhole within 0.5 feet of overtopping) and potential minor capacity iss`ues between manholes 5317-037 and 5317-185. Both of these situations would be affected by backwater from the downstream capacity problem. The City will monitor these areas to determine if evaluation is needed. The existing sewers in the Maplewood Division I and Division II plats were constructed in 1963. They are reaching the end of their useful life and should be scheduled for replacement. The model identifies a moderate backwater surcharge from King County between manholes 5316-015 and R10-26A. The system consists of approximately 2,000 lineal feet of existing 8, 12, and 15-inch concrete gravity sewer. The existing sewers in Windsor Hills are approximately 55 years old. Large portions of these sewers are 6-inch pipes, which do not meet current standards for minimum size for mains. Part of these sewers is within Zone 2 of the Aquifer Protection Area. The model identifies a potential severe capacity issue between manholes 5308-009 and 5308-026, with one manhole possibly overtopping. The City should schedule the replacement/rehabilitation of approximately 7,900 lineal feet of existing 6 and 8-inch gravity sewer in the Windsor Hills Neighborhood. The existing Heather Downs Interceptor has seen significant increased flows due to new development on a portion of the East Renton Plateau. Some flows directed to this interceptor was intended to be routed to the East Renton Interceptor. The model identifies three runs (5316-033 to 5316-037 - Moderate/Severe, 5316-038 to 5316-015 - Severe, and 5315-062 to 5315-001 - Moderate) within the Heather Downs Interceptor that have potential capacity issues. A section of the Heather Downs Interceptor was constructed on a very steep slope (approximately 65 percent slope). The sewer section in question is located along a power line easement near the plat of Maplewood. The interceptor was constructed using 10-inch PVC sewer pipe with concrete collars to stabilize the pipe on the steep slope. The City should video inspect this sewer to examine the internal integrity and to locate any pipe or manhole movement. If a problem is found, a geotechnical consultant could examine the steep slope for stability and the potential of soil shifting. This information will help determine the need for construction of an interceptor in a new alignment. A study needs to be performed to determine which portions of the system need to be upsized. The system • consists of approximately 9,100 linear feet of 8, 10, 12, and 15-inch mains. There is a stretch of Union Avenue NE, between NE 2nd Street and NE 6th Place that does not have a sewer main installed. There are three sections of sewer in this stretch that need to be installed to provide service to properties in this area that are undeveloped or on septic tank. Final 2010 5-17 The Cottonwood Lift Station was reconstructed in its entirety in 1994. This is a permanent ( station. The expected life of a sewage pump station is 25 years. Cottonwood will be 25 years old in 2019. Renton should plan to rehabilitate the station in 2019. 5.3.1.2 Model Basin RNT065 Model Basin RNT065 is located on the south side of Cedar River. This model basin includes primarily single-family and multi-family developments. This model basin includes two lift stations: the Falcon Ridge Lift Station and the Kensington Lift Station. In addition, this model basin receives wastewater from the Soos Creek Water and Sewer District. The Cascade Interceptor is a joint use facility between the City of Renton and the Soos Creek Water and Sewer District (formerly Cascade Sewer District). The gravity interceptor is currently not experiencing capacity problems, and King County's inverted siphon crossing the Cedar River was replaced by a new inverted siphon which is sized to accommodate these peak flows. The majority of the wastewater in this interceptor originates in the Soos Creek system, including Soos Creeks Lift Station No. 5. According to the Soos Creek Comprehensive Sewer Plan, Lift Station No. 5 is considered to be a permanent facility that serves a large basin. As development of this basin proceeds, increased pumping from the lift station may cause capacity problems in the joint use facility. Monitoring of the flows needs to continue, in order to minimize risk. • The model identified a potential surcharge of approximately 2 feet between manholes 5321-118 and 5321-016. This is due to the constant peak inflow assumption from the Soos Creek sewer system in the hydraulic model. The City will visually monitor this area to determine if modeled conditions match field conditions. The Falcon Ridge Lift Station was built in 1981. The expected life of.a sewage pump station is 25 years. Falcon Ridge will be 25 years old in 2006. As part of an overall review of lift stations for prioritization of upgrades or rehabilitation Falcon Ridge has been scheduled for replacement or rehabilitation in 2010. 5.3.2 East Cedar River Basin The East Cedar River Basin is located at the east side of Renton's sanitary sewer service area. The basin extends from approximately Bremerton Avenue NE to the Urban Growth Boundary east of the City. The majority of this basin is currently unsewered and consists of primarily single-family land uses. By ultimate buildout, it is estimated that the City would serve approximately 2,105 acres. A significant portion of this basin is already developed with subdivision. The majority of these developments are on private septic systems. Problems with some of the existing septic systems, the needs of the schools in the area, the lack of ability to develop existing platted lots on septic systems, and the desire by some to develop some of the larger tracts in the area highlight the need for sanitary sewers in Final 2010 5-18 this basin. The basin can be partially served by gravity through the East Renton Interceptor. Service of the central portion of the East Cedar River Basin will require an interceptor or conveyance facility to move the sewage from the sub-basin to the King County system. The first phase of this interceptor was constructed as part of the King County Elliott Bridge Construction Project that was completed in 2005. There is approximately 5,000 additional feet of 12, 15, and 18-inch sewer necessary to provide service to this basin. Service of the eastern portion of the East Cedar River Basin will require an interceptor or conveyance facility to move the sewage from the sub-basin to the King County system. The potential exists for a gravity route projecting south from 180th Avenue South. The completion of the East Renton Interceptor in 1994 allows for the extension of collection mains into the East Cedar River Basin. This basin has seen the most significant amount of improvement since the 1998 Long Range Wastewater Management Plan. Construction of the remaining collection system will be through LID or developer extension. There is approximately 220,000 feet of collection sewer necessary to provide service to this basin. There are also some facilities proposed in the basin that, while acting as local collector facilities, may need to be larger for conveyance purposes. While the City typically participates in the 'oversizing' costs of these lines this LRWWMP is not programming any CIP dollars for this project. Service of the Central Plateau area will require an interceptor or conveyance facility to move the sewage from this area to the King County system. The first phase of this interceptor was constructed as part of the King County Elliott Bridge Construction Project that was completed in 2005. Phase 2 began construction in 2007 with completion anticipated for mid 2008. Service of the East Plateau area will require an interceptor or conveyance facility to move 5 the sewage from this area to the King County system. The potential exists for a gravity route projecting south from 180th Avenue S. This and other gravity routes may be considered. There would be concerns about working in and around the Cedar River to cross to the Maple Valley Highway. Alternate methods of pipe installation, such as boring or micro tunneling may mitigate impacts involved with a river crossing. A gravity alternative would also be dependent upon a facility to move the flows from the discharge point of this trunk at approximately 177th to the existing King County Cedar River Trunk at 154th. For alternative consideration, a pump station that would move the flows to Model Basin CEDARO2A could be built in lieu of the East Plateau Interceptor. Both the East Renton Interceptor and the Central Plateau Interceptor are planned for this contingency. There is approximately 9,300 feet of 18-inch sewer necessary to provide service to this basin under the gravity alternative. The Evendell Lift Station can be abandoned when the gravity sewer system is constructed in 160th Avenue SE and the sewers serving south of SE 136th Street can be connected. Final 2010 5-19 The construction of the Central plateau interceptor allows for the connection and,activation of the dry sewers in the Briar Hills Neighborhood. The Highland Estates Lift Station can be abandoned with a short extension of gravity service. The East Renton Lift Station can also be abandoned by extending the sewer north from158th Place SE and SE 138th Place, approximately 900 feet. 5.3.3 East Lake Washington Basin The East Lake Washington Basin is located in the northern part of the City and includes Model Basins RNT023, RNT030, RNT035, and RNT054. The City serves this entire basin, which consists of a variety of land uses including single-family and multi-family residential, and light commercial. By buildout it is estimated that the developed area of the.basin would be 3,104 acres. The wastewater collected in this basin is transported to King County's East Side Interceptor at several connection points. The installation, in 1997, of the Sunset Interceptor allowed for the removal of the Sunset Lift Station. This interceptor was designed and. installed by the City, with King County's support, to relieve capacity concerns created by the County's delay in constructing the May Valley Interceptor. The Devil's Elbow Lift Station was rehabilitated in 1991, to provide reliability to the station and stabilize the location of the force main. The installation of the Sunset Interceptor removed the peek overflows, from the Sunset Lift Station, that used to flow to the Devil's Elbow Lift Station. 5.3.3.1 Model Basin RNT023 Model Basin RNT023 includes primarily single-family and multi-family developments. The sewers in this model basin are in good condition. As this basin becomes fully developed, the flows will cause a capacity concern along Lake Washington. This model basin includes the Devil's Elbow Lift Station. The sewer main in North 28th Place does, however, accept upstream flows from upstream areas. Modeling of this basin projects that this main does not have the capacity to handle full development of this model basin. The model projects potential surcharging of about three feet between manholes 5432-120 and 5432-118. The model identified a potential minor surcharging problem between manholes 5305-019 and 5305-041, due to a capacity issue. The Wastewater Utility should monitor the capacity of this line and program to upsize the mains. Parts of Sierra Heights have not had sewers installed. A large portion of this area has been declared an area of concern due to the potential of failure the King County Health Department has seen in the septic systems in the area. The majority of the unserved area is not currently within the Renton City Limits. Construction of sanitary sewers in the developed Final 2010 5-20 • areas will allow transfer of residential sewer disposal from private septic systems to a public ( sewer system. In early 1997, the sanitary sewer main in the 2900 block of Lake Washington Blvd. N was damaged by private construction. The sewer main was patched and put back into service. The repair is temporary in nature as it creates a reduction in capacity, impacts flow characteristics, and prevents proper cleaning. To properly re-establish the sewer system in the area the City needs to replace and relocate approximately 300 feet of sewer main. 5.3.3.2 Model Basin RNT030 Model Basin RNT030 includes primarily single-family and multi-family developments as well as the Highlands Commercial Center. This model basin includes the Westview Lift Station. This basin includes both residential and commercial developments. A major portion of the sanitary sewer system in the North Highlands area and South Highlands area were constructed during World War II. These older sewer systems are near the end of their useful life and require increased maintenance. The sewers in this model basin are on the City's list of highest priority sewers for evaluation of replacement. A major portion of the sanitary sewer system in the Presidents Park area is over 40 years old. Investigation of the old concrete mains finds the lines in moderate shape with some localized structural problems and some Ill. The model identified a potential severe pipe capacity issue between manholes 5309-439 and 5309-052 largely due to a flat sewers main. There is a projected surcharge of up to four feet during normal flows with the potential to overtop one manhole. The City should provide some spot repairs or rehabilitation to extend the useful life of the entire system. This area should be monitored for scheduling of replacement of the sewers. The existing collection system within the North Highland area was constructed in the early 1940s and is comprised of 8, 10, and 12-inch concrete sewers, which are approaching the end of their useful life and need to be replaced before structural failures occur. Within this North Highlands area, the model identified a moderate to severe pipe capacity issue between manholes 5309-011 to 5309-131. The model also projects that these capacity issues would cause a moderate backwater problem between manholes 5304-066 and 5309-011, which also has its own minor capacity issue. A potential severe pipe capacity issue is identified by the model between manholes 5309-024 and 5308-069. The model projects the possibility of one manhole overtopping. This project involves the replacement of approximately 56,800 lineal feet of existing gravity sewer between NE 7th Street, NE 21st Street, Aberdeen Avenue NE, and Queen Avenue NE. The existing collection system within the South Highland area was constructed in the early 1940s and is comprised of 8-inch concrete sewers, which are approaching the end of their useful life and need to be replaced before structural failures occur. This project involves the Final 2010 5-21 replacement of approximately 13,700 lineal feet of existing gravity sewer between NE 3rd Street, NE 7th Street, Monroe Avenue NE, and Sunset Boulevard NE. The existing collection system within the Westerly Portion of the Presidents Park area was constructed in the early 1940s and is comprised of 8 and 10-inch concrete sewers, which are approaching the end of their useful life and need to be replaced before structural failures occur. This project involves the replacement of approximately 10,000 lineal feet of existing gravity sewer between NE 6th Street, NE 10th Street, Monroe Avenue NE, and Harrington Avenue NE. The existing collection system within the Easterly Portion of the Presidents Park area was constructed in the Early 1950's and is comprised of 8-inch concrete sewers, which are approaching the end of their useful life and need to be replaced before structural failures occur. This project involves the replacement of approximately 32,000 lineal feet of existing gravity sewer between NE 6th Street, NE 10th Street, Monroe Avenue NE, and Harrington Avenue NE. The Westview Lift Station was constructed in 1996. Lift stations have an anticipated life of 25 years. This station has shown excessive wear and has reliability issues. It is schedule for replacement ahead of the 25-year time frame. 5.3.3.3 Model Basin RNT035 Model Basin RNT035 includes primarily single-family and multi-family developments as well as the portion of the Sunset commercial corridor east of Union Ave NE. This model basin includes the Long, Summerwind, Stonegate, and Wedgewood Lift Stations. The completion of the Sunset Interceptor and elimination of the Sunset Lift Station in 1997 removed many major capacity concerns. The majority of the sewers in this sunset area are around thirty years old. Stonegate serves single-family residential properties. The sewers in this area are newer with the oldest being approximately ten years old. It naturally flows toward May Valley. It is not anticipated that the May Valley Interceptor will be constructed within the six-year time frame of this LRWWMP. The model identifies a potentialmoderate to severe pipe capacity issue between manholes 5303-011 and 5303-069. The hydraulic grade line in MH 5319-057 comes within 3 feet of the surface. The City will monitor this area to determine if additional analysis is needed. The existing concrete gravity sewers in the Honeydew area are approximately 35 years old and have experienced severe corrosion. The City did some spot rehabilitation in this area to resolve Ill problems. Those pipe runs may not need to be replaced. The rest of the system, however, is structurally compromised. The City will be looking at the replacement of approximately 7,100 lineal feet of existing 8-inch gravity sewer between NE 10th Street, Sunset Boulevard, Union Avenue NE, and Hoquiam Avenue NE. Final 2010 5-22 The existing downstream system, from NE 10th at Field Avenue NE to the Sunset I Interceptor has insufficient capacity to accommodate future development flows from this portion of the system. The new interceptor would require 1950 linear feet of 12-inch sewer to connect to re-route flows to the East Renton System at Duvall Avenue NE and NE 8th Street. The Summerwind Lift Station is reaching the end of it's useful life. The Stonegate Lift Station is undersized to meet the build out needs of this area. The capacity of the sanitary sewer system in Duvall Avenue NE and NE Sunset Boulevard is also insufficient for build out needs of the area. Abandon Summerwind Lift Station and divert flows into Stonegate Lift Station. Construct a new Stonegate Lift Station with sufficient capacity to meet build out needs for both areas Construct new 8-inch force main to route flows to Field Avenue NE and gravity sewer main in Field Avenue NE and NE Sunset Boulevard. The Long Lift Station was built in 2001. The expected life of a sewage pump station is 25 years. The Long Lift Station will be 25 years old in 2026. The City should plan to rehabilitate the station in 2026. 5.3.3.4 Model Basin RNT054 Model Basin RNT054 includes primarily single-family and multi-family developments along Lake Washington and the Boeing redevelopment area located on the south end of Lake -_ Washington. The sewers in this area are approximately thirty years old. There are not any projected capacity concerns within this model basin. This model basin includes the Lake Washington Beach, Lake Washington Flush, and Lake Washington No. 2 Lift Stations. The Kennydale Lakefront sanitary sewer collection system is a low-pressure, force main. Water from Lake Washington is pumped periodically into the force main through the Lake Washington flush station. Lake water and the sewage is discharged from this low-pressure force main into the Lake Washington No. 2 Lift Station, where it is then pumped into the King County East Side Interceptor. The original force main was installed in 1972 and has a history of various problems and requires considerable maintenance. In 2003 the City installed three manholes over the Lakefront Sewer line located in Lake Washington. These manholes were installed to provide additional access for cleaning the sewer main of the solids that accumulate in the numerous bellies due to its location along the bottom of the lake. At the time of this construction, the line was thoroughly cleaned. The Kennydale Lakefront sewer system has several undesirable operating characteristics. First, this low-pressure sewer main requires a considerable amount of maintenance, which is made more difficult due to its location along the lakefront. Second, it uses a flush station which pumps water from Lake Washington in order to flush wastewater to the Lake Washington No. 2 Lift Station. In 2002/2003, the City performed a study to determine condition of the existing system and evaluate alternatives for replacement. The study recommended interim repairs and additional maintenance access points. Testing of the Final 2010 5-23 main for condition showed that it had potentially 20 to 30 years of additional life. Examine and evaluate system operation in this area and determine if replacement is warranted. The model identified a potential severe pipe capacity issue between manholes 5431-009 and 5432-141. The hydraulic grade line in MH 5431-007-007 comes within 0.5 feet of surface. The City will continue to monitor this area. The Lake Washington Beach Lift Station was constructed in 1968. This is a permanent station. The expected life of a sewage pump station is 25 years. While Lake Washington Beach is over 25 years old, it only receives seasonal usage from Coulon Beach Park and thus will last longer than 25 years. Renton should plan to rehabilitate the station in 2012 when the station is 44 years old. The Lake Washington No. 2 Lift Station was rebuilt from scratch in 1994:This is a permanent station. The expected life of a sewage pump station is 25 years. Lake Washington No. 2 will be 25 years old in 2019. Renton should plan to rehabilitate the station in 2019. 5.3.4 Black River Basin The Black River Basin is a large drainage basin in the southwest part of the City and includes the Model Basins RNT045 primarily single-family and multi-family developments in the uplands and the Renton Village commercial area by 1-405, SINT001 primarily light industry, warehousing and commercial, and SRENT002 primarily residential use, including both single-family and multi-family developments, and the commercial developments at and around Valley Medical Center. 5.3.4.1 Model Basin RNT045 Model Basin RNT045 includes primarily single-family and multi-family developments in the uplands and the Renton Village commercial area by 1-405. The higher elevations in the • Rolling Hills, Talbot Hill, and Panther Creek areas are generally single-family and multi- family residential developments, while the valley floor is generally industrial and commercial land uses. A large portion of the basin, south and west of SINT001-model basin were un- modeled. The model identified a potential pipe capacity issue between manholes 5319-085 and 5319-071 with the prospect of one manhole overtopping. The existing collection system within the Talbot Hills area was constructed in 1960 and is comprised of 8 and 10-inch concrete sewers, which will be approaching the end of their useful life and need to be replaced before structural failures occur. This project involves replacement of approximately 18,200 lineal feet of existing gravity sewer between Lake Avenue S, S 14th Street, State Route 515, and S 23rd Street. ' The Thunderhill Interceptor was installed in 1964 and is comprised of 10, 12, and 18-inch concrete sewers, which will be approaching the end of their useful life and need to be Final 2010 5-24 replaced before structural failures occur. The model identifies a potential Minor to Moderate pipe capacity issue between manhole 5319-046 and 5319-026. This project involves replacement of approximately 11,000 lineal feet of existing gravity sewer. The Benson Road Interceptor was installed in 1962 and is comprised of 8-inch concrete sewers, which are approaching the end of their useful life and need to be replaced before structural failures occur. This project involves replacement of approximately 5,500 lineal feet of existing gravity sewer. 5.3.4.2 Model Basin SINT001 Model Basin SINT001 includes most of the area south of Interstate 405, north of SW 34th Street, east of East Valley Road, and west of Oakesdale Avenue SW. This area is primarily light industry, warehousing and commercial. The flexibility of uses allowed in the zoning of ' the area may lead to increased demands on the existing sewer systems. Consequently, the City should periodically re-examine wastewater flow rates in order to better evaluate sanitary sewer needs. This model basin includes the Lind Avenue Lift Station. The Lind Avenue Lift Station was constructed in 1978. The station was rebuilt as part of a local improvement district in 1983. The expected life of a sewage pump station is 25 years. Lind Avenue will be 25 years old in 2008. This station is considered a permanent lift station, which will serve existing and future commercial developments within a major portion of the Renton Industrial area. It does not meet current design codes because it lacks full redundancy of its vacuum priming system. If the vacuum priming system were to fail, the lift station would not operate. In addition, the above grade electrical structures have experienced vandalism. The lift station requires rehabilitation and major modifications to improve reliability and in order to be upgraded to a permanent lift station. This station is currently scheduled to rehabilitate replaced in 2012. 5.3.4.3 Model Basin SRENT002 Model Basin SRENT002 is the majority of the area south of SW 23rd Street between SR- 167 and the eastern City Limits. This area is primarily residential use, including both single- family and multi-family developments, and thecommercial developments at and around Valley Medical Center. This model basin includes the Talbot Crest Lift Station. Renton obtained the sewer mains that allow the City to serve most of this area in the 1991 interlocal agreement with Soos Creek Water and Sewer.District. This agreement defines service area boundaries and results in joint use of the Springbrook Interceptor, which serves the Springbrook area. Renton is responsible for the portion of the Interceptor within City Limits and Soos Creek is responsible for the portion of the Interceptor outside of the City. The Talbot Road Interceptor is the only line that has capacity concerns in this model basin. This interceptor, which 'serves a majority of the model basins, may be undersized to service this area. As the area develops, the City should continue to monitor this interceptor for Final 2010 5-25 capacity and need to upsize. Additionally in the future, capacity constraints in the Springbrook interceptor may become a.concern. The 1991 agreement identifies capacity limits for both Renton and Soos Creek. Based upon these limits, the agency that is over capacity is responsible for improvements to provide the additional capacity. Based on the modeling effort, the analysis identified a potential pipe capacity issuein the South Talbot Interceptor, between manholes 5331-142 and R18-17. The capacity restraints are because of the relatively flat slope of the sewer and a minor backwater effect from King County's sewer. Five manholes in this run are projected with the possibility of overflowing. The model has identified two other runs connecting to this interceptor with capacity issues that are affected by backwater from this run. The run between manholes 5331-109 and 5331-182 projects with a moderate capacity issue. The run between manholes 5331-086 to 5331-025 projects to have a severe capacity issue with the potential of five manholes overtopping. The model also identified a potential pipe capacity issue between manholes 5331-056 and R18-25 with the possibility of one manhole overtopping. These areas will be monitored by City Staff. The existing Talbot Road Interceptor is potentially undersized to serve this basin. These existing 8-inch sanitary sewers may need to be replaced with 12-inch pipe. This project involves the analysis approximately 4,000 lineal feet of existing gravity sewer. The model identifies a potential severe pipe capacity issue between manholes 5330-109 and SR18-19, with six manholes possibly overtopping. The Talbot Crest Lift Station, which serves a residential development along Talbot Crest Drive, was replaced in 2001. Expected life of a sanitary sewer lift station is 25 years. As such, this station should be scheduled for rehabilitation in 2026. 5.3.4.4 Unmodeled Areas A large portion of the south and west portions of the valley floor is considered un-modeled. The City did not have individual meters in this area so the model was constructed using interpolated data from King County. This area is only a small portion of the King County metered basin and the results are showing themselves to be suspect. The City needs to obtain its own meter data for this area. This model basin includes the East Valley Lift Station. The existing SW 34th Street Interceptor is identified by the model as having severe pipe capacity issues between manholes 5330-037 and 5330-027 with intermittent surcharging up to four feet during normal flows and the potential for overtopping in six manholes. Part of the problem identified by the model is that the East Valley Lift Station is not keeping up with peak flows and backwater is affecting upstream conditions. Overtopping in six manholes. The City has not seen indication of a problem in this interceptor and is questioning the data. The City should perform an analysis of the approximate 3,500 lineal feet of existing 8- Final 2010 5-26 inch gravity sewer to determine if it is undersized to accommodate the area that can be potentially served with this interceptor. There are also several other areas that the model identified as having potential capacity problems. The City will monitor these areas to determine if future evaluation is needed. • A potential severe pipe capacity issue, between manholes 4325-037 and R18A-17 with one manhole possibly overtopping. • The model identifies potential large-scale pipe capacity issues between manholes 4336-001 and R18-17 with minor influence by backwater from King County. • Possible overtopping in twelve manholes. • Capacity issues between manholes 4325-038.and 4336-006 as a result of backwater. • Intermittent surcharging up to four feet between manholes 5330-037 to 5330-027 during normal flows. • Potential backwater effects from King County between manholes 5330-040 and R18- 11. The model indicates that the backwater capacity conditions in this section as influenced by lift station flows may cause three manholes to overtop. • Potential backwater and pipe capacity issues between manholes 5331-063 and R18- 05 and manholes overtopping between 5330-045 and 5330L19 due to the lift station not keeping up with incoming flows. It is important to note that the City has not experienced any overflows or high flow situations at any of these locations. Further analysis and potential additional flow monitoring may be required to better qualify these results. 5.3.5 Downtown Basin The Downtown Basin is located in the northwest part of the City and includes the Central Business District, West Hill and North Renton Industrial areas. The entire basin is model basin ESI1003. Land use within this basin consists of single-family, multi-family, commercial, and heavy industrial land uses. This model basin includes the Airport and Earlington Lift Stations. Skyway Water and Sewer District also provides sewer service to parts of the West Hill that are within this basin. The model identified potential capacity issues between manholes 5317-169 and 5318-115 due to relatively shallow slopes. There is a potential of four manholes overtopping. The model also indicates that this capacity issue may cause potential backwater situation between manholes 5317-205 and 5317-150 with the potential of three manholes overtopping. Additionally, the analysis identified potential severe capacity issues between manholes 5318-137 and 5318-148. No improvements are proposed for these areas, however they will be monitored by City Staff and evaluated as data is collected. Final 2010 5-27 The existing collection system in the Earlington Hill area was constructed in the early 1950's and is comprised of 6 and 8-inch concrete sewers, which are approaching the end of their useful life and need to be replaced before structural failures occur. The hydraulic analysis identifies potential minor pipe capacity issue between manholes 4313-109 and 5318-258. The model also identifies a potential moderate pipe capacity issue between manholes 5318-137 and 5318-148. Potential backwater affects from downstream influence the latter issue. This project involves the replacement of approximately 19,200 lineal feet of existing gravity sewer. - The existing collection system within the Renton Hill area was constructed between 1947 and 1949 and is comprised of 6 and 8-inch concrete sewers, which are approaching the end of their useful life and need to be replaced before structural failure occurs. This project involves replacement of approximately 15,000 lineal feet of existing gravity sewer. While the city has replaced a large quantity of the existing sewers in the Central Business District, there is still approximately 11,000 lineal feet of sewers that are old and in poor condition. The model identifies potential surcharging of less than 0.5 feet between manholes 5317-085 and 5317-086 during normal service and potential severe capacity issues between manholes 5317-089 and R01-21 during peak storm flows. Replacement of these sanitary sewer pipelines would improve sewer service to this area. The existing collection system on the West Hill (between NW 2nd, NW 7th, Rainier, and ( 84th Ave) was constructed in 1962 and is comprised of 6 and 8-inch concrete sewers, which are approaching the end of their useful life and need to be replaced before structural failures occur. The hydraulic analysis identifies potential severe pipe capacity issues between manholes 5318-013 and 5318-040 with the potential of one manhole overtopping. This project involves the replacement of approximately 25,000 lineal feet of existing gravity sewer. The majority of the existing gravity sewers between N 6th Street, N 4th Street, Wells Avenue N, and Park Avenue N are old and deteriorating. Further, these sewers were constructed with an inadequate slope that does not allow self-flushing of the sewer lines. Consequently, maintenance crews are required to flush these sewer lines approximately once a month. In addition, their condition has deteriorated and requires replacements. Interim repairs were made to these mains in the late 1990's. Replacement of approximately 3,100 lineal feet of existing 8-inch gravity sewer in this area is proposed. The North Renton Interceptor flows were reduced as part of the diversion through the Sunset Interceptor Phase II project completed in 2005. In addition, flows south of N 8th Street are being re-routed into a New 15-inch main being constructed in N 8th from Garden to Logan with a new connection to King County's East Side Interceptor. The City needs to evaluate the old interceptor line for rehabilitation, downsizing, and partial elimination. Final 2010 5-28 The sanitary sewer flows from the south east portion of this basin have been redirected to connect to King County's East Side Interceptor in S 7th Street. This has left low flows in the old 24-inch sewer pipe in Shattuck Avenue between S 4th Street and South 2nd Street. The reduced flows have resulted in septic conditions in the old pipe that require frequent flushing by maintenance crews. The City needs to replace and downsize 1,000 linear feet of 24-inch sewer main in Shattuck to 8 or 12-inch. Most of the Earlington area north of S 134th Street is currently unsewered. After construction of the Earlington Interceptor or replacement of the Earlington Lift Station, a collection system to serve this area may be completed. Existing businesses within Renton Center, fronting Rainier, contribute significant grease to the downstream sanitary sewer system causing backups and overflows. Replacement of the non-standard private sewer system with a City sewer main will allow the City to install testing stations to determine grease offenders. The new main would consist of approximately 800 linear feet of 8-inch sewer. The Earlington Lift Station currently serves the Black River High School near the intersection of S 132nd Street and S Langston Street. This lift station does not have the capacity to provide service for its projected area. The elimination of this lift station is possible since the completion of the sanitary sewer facilities for the Earlington Ridge Plat. The Airport Lift Station was rebuilt from scratch in 1986. This is a permanent station. The expected life of a sewage pump station is 25 years. Airport will be 25 years old in 2011 and should be rehabilitated. 5.3.6 May Creek Basin The May Creek Basin is located in the northeast part of the City and is located on the periphery of the City's.current service boundary. The portion of this basin within Renton's service area is currently only about half sewered. The remainder of the basin is within Coal Creek Utility District's service area. The City serves approximately 130 acres of this basin, which consists of primarily single-family and light commercial land uses. The ultimate sewerage of the southwest (City's) portion of the basin that is east of the freeway will be through the extension and completion of an interceptor to the south. Said interceptor to serve that portion of the basin would be mostly constructed in existing roads. It is not expected that the City would be considering extension of this sewer in the near future. There are large tracts of land within this area that are owned by Renton and/or King County as parkland. In addition, the properties between Jones Avenue and the freeway and the properties south of NE 36th Street that are within Renton's service area are zoned for such low density that any construction of the sewers may not be cost effective for possible development. Final 2010 . 5-29 The hydraulic analysis identifies potential severe problems in the Renton-Coal Creek Interceptor (Manholes 5429-024 to 5432-004). The ultimate model shows that this interceptor could potentially be within 0.5 feet of overtopping.The model identifies the problem as being caused by peak inflow assumptions from Coal Creek Utility District as part of the model. City crews will field verify model assumptions. At this time, the following three lift stations serve low lying areas along Lake Washington in this basin: Misty Cove, Baxter and Denny's Lift Stations. Because the Devil's Elbow Lift Station discharges into the East Lake Washington Basin, the Model Basin RNT035 is considered part of that major basin and it will be addressed in that section. Misty Cove Lift Station currently pumps into the Baxter Lift Station which pumps into the King County Sewer. The City should investigate pumping each station independently to the King County sewer. Misty Cove should be rehabilitated to ensure safe operation. Redevelopment in this basin,is another factor driving the need to replace or rehabilitate these stations. It is anticipated that Baxter will be replaced as part of the redevelopment of the area, with the City covering costs for oversizing. The Denny's Lift Station was built in 1983. This is a permanent station. The expected life of a sewage pump station is 25 years. The Denny's Lift Station will be 25 years old in 2008 and should be rehabilitated. Final 2010 5-30 Chapter 6 RECOMMENDED IMPROVEMENTS 6.1 INTRODUCTION This chapter presents the proposed improvements to the Renton sewer system that are necessary to correct existing deficiencies, replace existing deteriorated facilities and accommodate growth through the planning horizon. The costs of the improvements and a schedule for implementing them are also included. A thorough analysis of the sewer system was prepared to identify the improvements recommended in this Comprehensive Plan The recommended improvements identified in the Proposed Capital Improvement Plan in this Chapter are to be used as a guideline in preparing the capital improvements project list during each yearly budget process. This LRWWMP is deliberately intended to be flexible by allowing incorporation of necessary changes that might arise. Many of the proposed improvements are considered to be preventive in nature, i.e., the improvement is intended to happen before a specific facility has failed, a far more desirable process than trying to replace facilities after they fail. Since it is impossible to estimate when a facility will fail, the process of identifying those facilities that are at risk and planning corrective measures must continue. Additionally, as growth and land use patterns change during the planning period, the City will continue to evaluate the system. Future development may impact the size and timing of the proposed improvements. The City may recommend program modifications to best meet the needs of the wastewater utility system. 6.2 CIP RANKINGS • The complexity of the City's wastewater utility system requires a method that systematically determines which improvements should be undertaken sooner than others. To assign rankings to the planned improvements, each one was analyzed according to these general categories: Substandard Facility, System Efficiency, and Environmental Protection. Substandard Facilities evaluate hydraulic capacity or structural problems, System Efficiency improves operational conditions and Environmental protection meets regulatory criteria. For consistency in Capital Improvement Program (CIP) development and ranking, these are the same categories used during the 1998 Long Range Wastewater Management Plan. Each category was further divided into four or more kinds of improvements or standards. Each of these sub-categories was assigned a number of points, with the rule that no one improvement could be given more than eight points in any of the three categories. For each sub-category, each proposed project was given one point if it provided the benefit described and two points if it provided a solution to an acute problem. The higher the number of points an improvement received, the greater its benefit, or the greater its ability to meet certain standards or policies. This systematic ranking will help direct resources and activities to the appropriate projects. The results of the systematic ranking are presented in Table 6.1., Each project is identified as a general system wide improvements or a basin specific improvement. A project Final 2010 6-1 number.was assigned to each individual project, according to the project group location,i.e. System Wide are 1.0x project and West Cedar River Basin are 2.0x. 6.2.1 Substandard Facility A facility qualifies as substandard if it is unreliable, is structurally deteriorating or has hydraulic capacity problems. A project received points if it resulted in the following improvements to a substandard facility: - POINTS: 1-2 Reduces or eliminates hydraulic capacity problems. 1-2 Replaces a deteriorating facility or corrects a structural problem. 1-2 Improves system reliability (i.e., prevents discharge of raw sewage to any waters, or reduces the potential backup of raw sewage into basements, streets, or other properties). 1-2 Corrects occupation hazard (i.e., reduce dangers to maintenance workers). Maximum Number of Points: 8 6.2.2 System Efficiency A project can improve the efficiency of the system if it results in a reduction of operation and maintenance costs. Examples of such projects include wastewater flow rate modeling and elimination of lift stations. A project received points for system efficiency if it met any of the following conditions: POINTS: 1-2 Involves improving lift station operation or efficiency. 1-2 Involves the elimination of a lift station. 1-2 Reduces infiltration and inflow. 1-2 Improves understanding and planning of sewer system. Maximum Number of Points: 8 6.2.3 Environmental Protection An improvement helps protect the environment if it reduces damage to it, or reduces the threat to the public health. Examples of deficiencies that such projects improve include failing septic tanks or sewage overflows into lakes or streams. An improvement received points for environmental protection if it met any of the following conditions: POINTS: 1-2 Eliminates septic tanks. 1-2 Improves protection of the public health and safety. 1-2 Improves protection of the environment (i.e., land, wetlands, streams, groundwater). 2 Helps protect Zone 1 of Aquifer Protection Area. 1 Helps•protect Zone 2 of Aquifer Protection Area.

The total ranking sum cannot be used solely to prepare the Capital Improvement Program. The project rankings do not take into consideration engineering judgment or scheduling of dependent projects. Engineering judgment involves the trained observation of non-quantifiable impacts of a project. The scheduling of projects involves determining which projects must be completed before other projects can begin. For thesereasons, each project wasreassigned into three priorities categories: near-term, mid-term, and long-term. Table 6.2 presents the total ranking and the project priority along with brief comments regarding any inconsistency between the project ranking and the project priority: 6.3 CAPITAL IMPROVEMENT DESCRIPTIONS The proposed capital improvement projects are summarized in the following section. The projects are organized by drainage basin. A brief description of the specific system deficiency and the proposed improvement are included. The improvement also includes the total estimated project cost. The costs are in 2008 dollars. They were developed based on prior project cost data, which was then inflated to 2008 dollars. The total cost includes the project design, construction and all other allied costs. The estimates are based on approximate average costs for similar project, and do not take into account individual variables. The projects will require a revised cost estimate prior to the initiating of any of the capital projects, in order to account for the other variables. Each project was assigned a proposed schedule date based on the priority. Lastly, each project includes a site map with the project extents. A summary map of all recommended improvements is included as Figure 6.1. 6.3.1 System Wide Improvements 1.01 Miscellaneous Sewer Projects and Emergency Repairs System Deficiency: This project is to perform small repairs, replacements, or installations of sewers that are not scheduled in the CIP, but become a priority due to unexpected problems, failure, or coordination with other projects. Improvement: Identify and perform non-scheduled work as necessary. • Cost: $2,020,000 Priority: near-term • Beginning: 2006 Completion: 2026 1.02 Lift Station Telemetry Upgrades System Deficiency: Telemetry system components and software will become out-dated over time.

This model will need to be updated as the sewer system is expanded, flow monitoring data collected, physical system data collected by survey or field inspection and as software is updated. Improvement: Update model annually to ensure its accuracy. • Cost: $500,000 Priority: near-term • Beginning: 2006 Completion: 2026 1.04 Inflow& Infiltration Metering, Investigation, and Rehabilitation and Replacement of Sanitary Sewer Mains for Control System Deficiency: Old and aging sewers contribute to excessive inflow and infiltration into the sanitary sewer system. In conjunction with King County's program for reducing infiltration and inflow (I/I), the City identifies areas of concern for investigation, additional metering, and replacement or rehabilitation of the sewers. There are certain portions of the sanitary sewer system that are known as having excessive I/I. If these systems are replaced, I/I will be reduced and King County's requirements will be met. If a system is not scheduled for replacement or a replacement is delayed, the City may have to perform interim rehabilitation to reduce I/I. The sewer model has also identified portions of the sewer system that have I/I or capacity problems that have not manifested themselves with physical signs. The City needs to perform additional metering and investigation of these areas to determine the accuracy of the model, update the model data, and determine the level of need for replacement or rehabilitation. Improvement: Perform additional metering and investigation of the sewer system. Replace or rehabilitate existing sewers with I/I problems. • Cost: $2,280,000 Priority: near-term • Beginning: 2006 Completion: 2026 Final 2010 6-11 1.05 Sanitary Sewer Main Replacement and Rehabilitation System Deficiency: The City's existing sanitary sewer system consists of varied materials and age.

This basin has seen the most significant amount of improvement since the 1998 Long Range Wastewater Management Plan. Construction of the remaining collection system will be through Local Improvement District or developer extension. There is approximately 220,000 feet of collection sewer necessary to provide service to this basin. Two interceptor projects providing service to this basin are described in projects 3.02 and 3.03. There are also some facilities proposed in the basin that, while acting as local collector facilities, may need to be larger for conveyance purposes. While the City typically participates in the 'oversizing' costs of these lines this LRWWMP is not programming any CIP dollars for this project.

The potential exists for a gravity route projecting south from 180th Avenue South. This and other gravity routes may be considered. There would be concerns about working in and around the Cedar River to cross to Maple Valley Highway. Alternate methods of pipe installation, such as boring or micro tunneling may mitigate impacts involved with a river crossing. A gravity alternative would also be dependent upon a facility to move the flows from the discharge point of this trunk at approximately 177th to the existing King County Cedar River Trunk at 154th. For alternative consideration, a pump station that would move the flows to either the North Plateau Sub-basin or East Renton Sub-basin could be built in lieu of the East Plateau Interceptor. The East Renton Interceptor was sized and the Central Plateau Interceptor is planned for this contingency. f There is approximately 9,300 feet of 18-inch sewer necessary to provide service to this basin under the gravity alternative.

First, this low-pressure sewer main requires a considerable amount of maintenance, which is made more difficult due to its location along the lakefront. Second, it uses a flush station which pumps water from Lake Washington in order to flush wastewater to the Lake Washington No. 2 Lift Station. In 2002/2003, the City performed a study to determine condition of the existing system and evaluate alternatives for replacement. The study recommended interim repairs and additional maintenance access points. Testing of the main for condition showed that it had potentially 20 to 30 years of additional life.

It may be possible to eliminate one of these lift stations by providing gravity sewer from the Baxter Lift Station to Misty Cove. The Misty Cove Lift Station has sufficient wet well volume to accommodate this change. The City should also investigate pumping each station independently to the King County sewer. Redevelopment in this basin is another factor driving the need to replace or rehabilitate these stations. It is anticipated that Baxter will be replaced as part of the redevelopment of the area, with the City covering costs for oversizing. Misty Cove will be rehabilitated to ensure safe operation.

Final 2010 6-61 Chapter 7 OPERATIONS AND MAINTENANCE 7.1 INTRODUCTION The following chapter summarizes the City's current operation and maintenance (O&M) program, organization structure and staffing, and future program needs. This chapter establishes the duties, discusses the manhours required, and spent on each O&M program and records the current preventative maintenance schedule. 7.2 ORGANIZATION STRUCTURE The sewer utility operates under the direction of the Public Works Administrator. The Wastewater Maintenance Supervisor reports to the Wastewater Manager who intern reports to the Maintenance Services Director. The Wastewater Utility Engineering Supervisor reports to the Utility Systems Director. The Utility Systems Director and the Maintenance Services Director report to the Public Works Administrator. Figure 7.1 shows the City's O&M organization structure. The Wastewater Maintenance Supervisor and Wastewater Manager evenly divides their duties, overseeing the O&M of the sanitary sewer and storm water systems. There are two Lift Station technicians and five Maintenance Services workers responsible for the operation of the sanitary sewer system. The Wastewater Utility staff is responsible for design and management of capital improvement projects, coordination of developer extensions of the sewer system, and long range planning for the Utility. The Wastewater Utility Engineering Supervisor oversees the Wastewater Utility staff. The Wastewater Utility Engineering Supervisor is also responsible for the management of the City's Technical Services Section. Time division between the two sections is 60 percent Wastewater and 40 percent Technical Services. The Wastewater Utility staff consists of two engineering project managers, one grease/industrial waste specialist and a 0.5 full-time employee (FTE) GIS specialist. 7.3 STAFFING The wastewater utility is staffed by both Maintenance and Operations and Engineering teams. The primary roles of each team, summary of programs, and estimated staffing levels are summarized in the following sections. Final 2010 7-1 *tY stAP Public Works Administrator Utility Systems Maintenance Services Director Director Wastewater Utility Wastewater Engineering Supervisor Manager Engineering Project Managers(2) Wastewater Maintenance Supervisor Grease/Industrial Waste — Lift Station Technician (2) Specialist(1) GIS Specialist(.5) Wastewater Maintenance Services Worker(5) FIGURE 7.1 OPERATIONS AND MAINTENANCE ORGANIZATION STRUCTURE LONG-RANGE WASTEWATER MANAGEMENT PLAN City of Renton c 7.3.1 Maintenance and Operations Staff The current staff organization is described in Section 7.2 of this chapter. There are at present eight full-time employees (FTE), including supervisory personnel and maintenance workers, who operate and maintain the sanitary sewer system. The tasks that are performed by sewer utility staff include inspection, testing, installation and repair of system facilities and preventive maintenance, corrective maintenance, record keeping, administrative tasks, training, and response to emergencies. Wastewater Maintenance has developed a program to maintain the existing system. First level of priority is the inspection and maintenance of the portions of the system that are known to have problems if not handled on a weekly, monthly, quarterly, or annual basis. This includes the inspection and maintenance of lift stations, areas of known root problems, and areas of known grease problems. The second level of priority is the routine inspection and maintenance that is required to identify any additional high priority maintenance issues and to find potential random issues that may cause problems for the customers. The second level of priority include television inspection of the system and hydraulic line cleaning. It is typically recommended by insurers involved with utility system management that, in order to minimize claims against the utility, that the entire system should be inspected approximately every five years. Since line cleaning is performed prior to television inspection, this would also mean the entire system is cleaned approximately every five years. The estimated hours of work required to adequately maintain the sanitary sewer system are shown in Table 7.1. For maintenance activities, the annual hours total 13,735. The hours of work required for operational tasks for the sanitary sewer system are shown in Table 7.2. For operational tasks, the annual hours total 3,346. For adequate maintenance of the sanitary sewer system, the City would need a total of approximately 17,081 hours (the sum of maintenance and operational tasks) worked per year. The City spends approximately 14,350 hours per year on operations and maintenance. This is approximately 2,731 hours short of the hours estimated to operate and maintain the sanitary sewer system. The first level priority tasks are being completed. Routine inspection and maintenance are falling behind. This increases the risk of problems with the system. The City must evaluate the risk and determine if additional staff is required to meet this workload. As the City's capital projects have focused on capacity related improvements, this has required additional main repair and maintenance. As staff has focused on preventative maintenance,.other activities have received less attention. This is an issue that needs to be evaluated in more detail beyond this LRWWMP.

Further staff increases should be tied to the actual growth of the sewer system. Over the last ten years the City has added approximately 13,000 feet of sewer per year to the system. An expansion of the system requiring new service connections and/or additional facilities, without enlargement of the staff, will result in diminished levels of service for all maintenance programs. In view of predicted population growth in the service area over the next several years and the growing demand for sanitary sewer service, an increase in the size of the sewer system could be projected to continue at a similar rate of growth. With that increase in demand, there may be a need for additional staff. Final 2010 7-4 Maintenance and technical staff additions may be accompanied by additions to the clerical, secretarial, and other support staff needed to ensure that record keeping, billing, public relations, communications, and other general functions of support staff are performed with the accuracy and timeliness required.

Currently the Wastewater Utility has 4.1 FTE's involved in engineering tasks. The engineering staff is responsible for two major tasks, administrative, and capital improvement projects. The various tasks and the hours of work required are shown in Table 7.3. The number of hours required for each task is not easily defined; therefore, workloads have been estimated based on a FTE. Administrative tasks require approximately 2.4 FTE's. Additional administrative tasks that are recommended in this LRWWMP are (1) prepare new ordinances and revise existing ordinances, (2) setup and administer grease trap management and certification ordinance, (3) inventory and update hydraulic computer model, and-(4) perform computer analyses using the sewer system hydraulic model. These tasks will require additional City staff or other resource staffing alternatives. Maintaining the system inventory data, data coordination with the hydraulic model and development of an asset management program with the maintenance management system for the Wastewater Utility is a key area that may not have current staffing resources available. The City should look at the need to convert the 0.5 FTE GIS specialist to a full FTE for this work.

The Finance and Information Services Department is responsible for customer billing, payment collection, project cost reporting, fund activity reporting, and basic computer needs. The Human Resource and Risk Management Departments are responsible for employee records, union labor negotiations, salary schedules, and risk management evaluation. Within the Public Works Department, the Wastewater Utility utilizes the services of the Technical Services Section. Technical Services provides support to Wastewater through Mapping and Property Services. This includes CAD mapping, development of the City's geographic information system, surveys, and property management. Within the Department of Community and Economic Development, the Wastewater Utility utilizes the services of the Development Services Division. Development Services provides plan review, permit issuance, and inspection for developer extensions. They also provide inspection service for the Utility's Capital Improvement Projects. 7.5 RECORDS Providing time for keeping and maintaining accurate records should be an integral consideration in determining the time to be allotted to any departmental task. Adequate records are an essential tool in utility management and operation, providing the supporting Final 2010 7-6 data for operations assessment and long-term planning, while saving time and reducing difficulty when trouble arises. Currently, the City's management software is outdated and hard to utilize for today's environment with multiple tasks for each component. The City plans to purchase a maintenance management system to better track time for each system component. The sewer utility has need for several types of records: Facility operation, personnel, customer contact, inventory, and facility maintenance and repair. These and other appropriate documents should be legible, concise, permanent, accurate and accessible. Their importance to the efficient functioning of the utility is critical. Up-to-date maps of the sanitary sewer system are important for O&M. Changes or additions to the sanitary sewer system should be added as they occur. The City maintains an updated GIS map of the sanitary sewer system that is useful to the O&M staff. These utility maps, printed in 1"=400' books and 1"=800' wall maps, show the sanitary sewer size and location, manhole location and number, cleanout location and number, and lift station and force main locations. The City is also developing a geo database inventory of the sewer system that links the GIS maps with the as-built drawings. As-built drawings of much of the existing sanitary sewer system and private side sewers are kept on file by the City. Some of the original maps are stored in the Utility Systems Division at City Hall and because of storage constraints, some are stored at the City's . maintenance facility. This information is available in both hard copy and as scanned images available to be viewed on,a computer. The O&M staff uses this data to provide location information for sanitary sewer lines and service connections. Plat maps or construction drawings for new sanitary sewer extensions within the distribution system should continue to be kept for the sanitary sewer system and added to both the CAD and database systems. The Wastewater Utility is currently working to get its as-built data into a central database,. such as ESRI, to allow for improved methods of accessing the data, updating the data, and use of the data. 7.5.1 Telemetry Successful operation of any municipal sewer system requires that the municipality maintains a comprehensive maintenance program and that they obtain accurate sewage flow rate information. A telemetry and control system is the means by which flow rates are measured and maintenance needs are updated. A radio-based telemetry system was completed in 1996 to replace the City's existing tone telemetry system. Each lift station is controlled by a digital based Remote Telemetry Units (RTU) to allow custom control to match the characteristics of each individual lift station. The telemetry system provides a method for logging and controlling the entire City's lift stations from a central location at the City's Maintenance shops. Operating data from each Final 2010 7-7 lift station is stored on a Master(data-logging) Computer for record and later use. This ( information is used in a comprehensive maintenance program to help eliminate costly station down time that can often cause damage to adjacent property owners and the environment. The control algorithms located on the Master Computer and the RTUs can be used as trend analysis to detect possible problems earlier. The Master computer displays wet well sewage levels and time to overflow data for all of the City's 25 lift stations (two of the 25 stations are storm water stations). This information can be used to help manage the lift stations in a citywide power interruption that could occur after a natural catastrophe. The telemetry system can be monitored and controlled by a remote computer link using specialized software. The pumps main control system is controlled from a level sensor in the wet well. A back-up float switch system has been installed at most of the lift stations to provide redundant protection from costly overflows in the event of control failure. Smaller stations, serving twelve or fewer single-family homes, may utilize floats as the main control system. The master telemetry unit, located at the City Shop, includes an intelligent telephone dialer alarm system, so that critical alarms can be relayed to on-duty maintenance personnel, even during a telemetry system failure. 7.5.2 Asset management Currently, the City does not own an asset management program. The City currently plans to purchase a new software system for maintenance management software (EAM). This system will be the first stage of the City's asset management system in coordination with the City's GIS database and hydraulic model. 7.6 CURRENT OPERATION AND MAINTENANCE PROGRAM Duties involved with running the Wastewater Utility are divided into O&M programs. These programs are discussed in the following sections. 7.6.1 Maintenance The maintenance program is composed of both preventative and corrective maintenance. Preventive maintenance uses planned and scheduled activities to ensure smooth, continuous operations of equipment and facilities. Maintenance schedules, that meet or exceed manufacturer's recommendations, should be established for all critical components in the sanitary sewer system. The City's new sewer telemetry system provides automated data collection and record keeping of lift station functions. Physical inspections of the stations are still an important tool in maintaining the system. The preventative maintenance programs include: lift station inspection and maintenance, manhole inspection and maintenance, video inspection, root cutting, grease removal, and hydraulic line cleaning. Corrective maintenance is that which improves the performance of existing equipment, Final 2010 7-8 facilities and infrastructure. The corrective maintenance program is mainly composed of repairing sewers and clearing plugs. The following section describes the O&M program for each category outlined in Table 7.1. 7.6.1.1 Lift Station Inspection and Maintenance The City maintains 23 lift stations throughout the system. The City has assigned two staff members to the maintenance activities. The two members do not have any backup staff members. The following describes the inspection and maintenance program for the sewage lift stations and wet well facilities: Sewage Lift Stations Inspection and Maintenance The City has on-call staff 24-hours per day. They also perform a daily inspection of the telemetry at each station. Every week the City performs an inspection of each lift station. This weekly inspection includes a security check, recording pump motor hours, checking motor noise, temperature, and vibration. The City changes all filters, cleans electrodes, exercises all valves, and runs each emergency generator on a monthly basis. On an annual basis, the City checks the pump bearings and seals, tests the entire electrical system at each station, and performs an infrared test of the system. Wet Well Facilities On a weekly basis, the City checks the security, float settings, and operation of each wet well. The City washes down each wet well, checks the interior condition, ladders, hatches, etc. in each. • The City performs a pump down of each wet well once a year. They take this time to clean the wet well. The lift station crew uses a vehicle equipped with a crane to lift pumps, equipment, utility compartments for parts, tools, etc for the lift station maintenance program. 7.6.1.2 Manhole Inspection and Maintenance The City has identified 89 problem areas in the collection system. The City's personnel inspects the sanitary sewer manholes in those areas weekly for the following situations: 1. A visual guarantee of proper sewage conveyance. Final 2010 7-9 a. Clean lines when flow in sewers is reduced. 2. Assessment of the state of solids buildup in manhole wet wells. The examination works in conjunction with the hydraulic line cleaning and video inspection programs (to be discussed later). 3. Verification of the condition of the manhole lid/cover and support rings for wear and stability. The City replaces worn rings and lids as needed. 4. Visual affirmation of condition of sewer channels and ladder rings. The City inspects the remaining manholes in conjunction with the video inspection program. Maintenance staff perform the same inspections and maintenance on those manholes at that time. The City uses a line service truck for inspection and repair of manholes and lines. It carries parts used in sewer line repair and repairs to manholes are made as needed. 7.6.1.3 Video Inspection Routine video inspection of the sanitary sewer system is an essential part of the maintenance responsibilities. Structural correction and obstructions are the primary cause of line failure in sanitary sewer pipes. Routine inspections of the lines are crucial to be aware of potential trouble spots. Sewage spill claims have proven to be a very costly type of litigation for municipalities to deal with and routing video inspection of the sewer system is the first line of defense. The video inspection unit is a closed-circuit color TV system used for inspecting sanitary sewer and storm drain lines. Its primary use is to determine conditions of existing lines and any repairs or replacements necessary. The TV van is an important part of the maintenance program to help determine priority areas that require further attention and maintenance. 7.6.1.4 Root Cutting Routine sewer facility inspection commonly identifies root intrusion within both private and public sewer mains. If the problem is within the City right-of-way, the City will correct the problem and remove the root. A hydraulic root cutter is used to routinely remove roots that accumulate within sewer lines creating flow restrictions and blockages. Numerous lines throughout the City have been examined and discovered to have had a history of problems created by roots. These particular lines are rodded more frequently to ensure there is no interruption of flow. 7.6.1.5 Grease Removal Grease problems are typically associated with major food processing operations, the majority of which involve restaurants where grease is a component of the wastewater. Final 2010 7-10 Many of the older restaurants within the City do not have grease removal systems. Newer restaurants have been and will continue to be required to install grease removal systems. However, many grease removal systems are not properly maintained. Grease buildup problems occur most often in the side sewers. However, some grease buildup problems also occur in the sanitary sewer collection system. When problems do occur, the City maintenance crews are usually called out to investigate. A proper monitoring program reduces maintenance time involved in removing grease buildup. The City has achieved moderate success in noting problems and identifying the sources. The Wastewater Utility has also worked with new construction and tenant improvements to ensure that these users are installing proper grease removal systems and/or bio-agent facilities. The City has recently started a grease removal program for standard food- services establishments and multifamily housing to improve grease collection at these facilities. This program needs continued effort to implement the program to new establishments. 7.6.1.6 Hydraulic Line Cleaning The sewer lines are cleaned with a vacuum-high velocity cleaning/jetting truck, which performs two primary functions: vacuuming and jetting. Jetting a sanitary sewer pipe is the principal means of cleaning the line portion of the sewer of sludge, debris, or obstruction. A hose with a special end fitting is inserted into a pipe and high-pressure water (up to 2,500 pound per square inch) is sent through the hose. The high-pressure water exits the small hole at the tip of the cone fitting, breaking down the sludge and obstructions. The hose is propelled down the length of the pipe via the numerous other holes found in the end fitting. The hose is inserted through a manhole into the pipe and the line is jetted to the next manhole. The hose is then retracted via a motor driven reel system, back to the entry manhole. All of the sludge/debris is scoured toward the entry manhole because the spraying water forces it in that direction and is vacuumed out as required. There are a number of lines in the City that have inconsistent grades creating septic conditions within the lines. A part of the maintenance program is to use the Vac-Con to flush water through these particular lines periodically to prevent those conditions from occurring. The Vac-Con is the primary equipment used for emergency blockages in the lines and is used to assist TV inspection. 7.6.1.7 Repair Sewers and Clear Plugs When problems with the sewers are identified through the preventative maintenance program described above, repairs are made to the infrastructure or clogs are removed. The preventative maintenance program is efficient and typically represents only 1 percent of the maintenance manhour allotment. The City spends approximately 106 hours clearing plugs and 334 hours repairing sewer lines. Final 2010 7-11 7.6.1.8 Easements and Access Road Maintenance In addition to public roads, the City operates, maintains, repairs and constructs sewer mains, and lines in, over, along and under roads and easements located within the sewer service area. As the utility performs work within the easements, minor roadwork and improvements are necessary. All work done within the easements shall be done in accordance to any permits and City and County standards. 7.6.2 Operations The sewer utility has a comprehensive system operation manual describing system operational procedures. Although this manual is outdated, the City has maintained the policy of requiring complete O&M manuals for all new equipment and facilities. It is recommend that the O&M manual be updated on a routine basis. The following section describes the operations program outlined in Table 7.2. 7.6.2.1 Administrative Duties The key administrative duty of the City's operation staff is to establish routine operation duties and schedules. Routine operations involve the analysis, formulation, and implementation of procedures to ensure that the sanitary sewer facilities are functioning efficiently. The utility's maintenance procedures work well. Repairs are made promptly so customers do not experience unnecessary inconvenience. Additionally, the operations staff establish emergency operations procedures for operation during such emergencies. The primary objectives of these procedures are to ensure public safety, restore essential services as quickly as possible, and to provide assistance to other areas as required. Emergency operations are described in the following section. Side sewer maintenance is a major problem within a sanitary sewer system. It is the City's policy that individual property owners are responsible for maintaining their side sewers. If a problem occurs, it is the property owner's responsibility to contact a private plumber to investigate and correct the problem. 7.6.2.2 Emergencv Operations Emergency operations are the unplanned and unscheduled tasks needed to keep the system in operation. This would include responding to sewer blockages, pipes broken by construction, and damage to the system by acts of nature. All of the maintenance staffs are also available to aid any of the other sections with additional manpower or equipment. The Wastewater Maintenance staff also has the responsibility to keep the system operating when there are power or mechanical failures at lift stations. The City's telemetry system allows for 24-hour remote monitoring and access to the system by the crew. With this access, they can be alerted to a problem and correct it remotely, determine that it can wait Final 2010 7-12 until the next shift, or mobilize the necessary manpower and equipment. The City follows all Department of Ecology guidelines for emergency notification procedures. 7.6.2.3 Tools and Equipment Cleaning Sewer maintenance staff is equipped primarily with City-owned equipment. The equipment available for daily use includes rolling stock, shop tools and incidental equipment as well as other portable equipment for field use. The vehicles and other rolling stock are listed in Table 7.4 with a description of their primary use in the department. A description of each vehicle and its uses is presented below. Tools & Equipment-- Rolling Stock Daily: Check all fluid levels and brakes As Needed: Replace fluids and filters in accordance with manufacturer's recommendations (or more frequently depending on type of use) Tools & Equipment--Tools As Needed: Clean after each use; lubricate and maintain as necessary. The existing inventory appears adequate at current staffing levels, but should increase in proportion to customer increases. The City should examine the backup capabilities of the inventory, based on critical equipment or facility failure, and make provisions for additional material procurement on a short notice.basis where necessary.

The normal channels of communication available to maintain effective coordination are: 1. Vehicular two-way radios 2. Cellular Telephones 3. Electronic Pagers 4. Regularly kept work logs 5. Regular inspection reports 6. Daily work assignment meetings 7. Inventory and other record keeping practices 8. Emergency phone numbers for"on-call" employees 9. Direct, City-owned telephone connection to City Hall 10. Weekly staff meetings As the complexity of the system increases and as the service area expands, the need for trained efficient staff to keep pace with public demand and advances in technology will become imperative. New employees need orientation and basic information; while more experienced employees can improve by continued training. Training opportunities are of such importance to effective operation of the system that Renton has linked them to its overall personnel evaluation program. Employees are evaluated and promoted through a set of job categories with pay commensurate to the category. It is essential that the promotional program continue to be closely linked with the training program, not only because it promotes efficient operation, but also because mandatory certification of wastewater utility workers is required by the state. The State Final 2010 7-14 Department of Health stipulates qualifications and training requirements for obtaining and maintaining certification. 7.7 FUTURE OPERATION AND MAINTENANCE NEEDS The City's is considering adding the following items to the improve the function of the current O&M program: • Purchase software for maintenance management system. This will enable the City to better assess and manage their assets. This software will be the beginning of the City's asset management program. • Research assessed management programs and develop recommendation for the City that incorporates the new maintenance management system, the City's GIS data base, and the hydraulic model. • Update the City's existing Operation Manuals to account for regular and emergency operation practices. • Further develop a Grease program to reduce the introduction of grease into the City's sewer system. • Evaluate the addition of new staff to enable the City in completing their yearly operations and maintenance goals. • Establish a succession plan and mentoring program. Final 2010 7-15 Chapter 8 FINANCIAL ANALYSIS 8.1 INTRODUCTION This chapter considers the financial impacts that the Capital Improvement Program (CIP) and Operation and Maintenance Program, recommended in Chapters 5 and 6 respectively, will have on the wastewater utility's budgeting process. The proposed wastewater utility CIP consists of the rehabilitation, replacement and new construction of sewer facilities that are necessary to meet the policy goals stated in Chapter 3, the design standards and criteria and the service needs that will result from anticipated growth presented in Chapter 4. This chapter also presents a financial analysis of the wastewater utility that identifies its historical and projected future expenses and compares them to available and projected revenues in order to determine the necessary rate adjustments. A utility rate model that evaluated the operation of the 406 and 426 funds and made specific rate recommendations was completed as part of the 2007 Utility Rate Study completed by FCS Group for the City's Wastewater, Water, and Surface Water Utilities. This model took the previous model developed by EES Consulting in 1994 and updated all assumptions and projections to reflect the current financial policies for the utility. Current 2008 dollars are used to project the costs of operations, maintenance, and capital improvement programs. However, several factors may affect the'accuracy of those projections. The most significant factor is inflation. Although we cannot predict the exact amount inflation will increase costs, inflation rates were assumed to range between 3 and 7 percent and are summarized in Table 8.1. Additionally the City cap on budget increases was assumed to be 2 percent and fund earnings were assumed to be 3.5 percent. Other factors that may affect future costs that we have not included in our cost estimate are contractor availability, technological advances, and changes in laws and policies. Table 8.1 Inflation Rate Summary Long-Range Wastewater Management Plan City of Renton Cost Class Assumed Growth Rate General Costs 4% Construction 5% Labor 3% Benefits 7% General Inflation + Growth 5.56% Final 2010 8-1 8.2 PAST FINANCIAL PERFORMANCE Table 8.2 compares the 2008 budget for wastewater operations to the 2006 actual spending and the 2007 budgeted expenses. As shown in Table 8.2, the City is expecting a 14.3 percent increase in revenue sources primarily due to a 12.6 percent increase in charges for goods and services. The City is also planning for a 14.3 percent increase in expenditures. The largest increase in expenditures is from regular salaries, benefits and debt services. Table 8.3 summarizes breaks down the 2007 budget into operating and CIP expenses. 8.3 CURRENT REVENUE The primary revenue source for the City is through charges for goods and services. These charges are divided into three categories: rates, charges and fees. 8.3.1 Rates Table 8.4 summarizes the City of Renton and King County wastewater rates for single- family and other uses. The City charges single-family connections a monthly fee of$15.55 for collection and transport while King County charges single-family connections a monthly fee of$28.51 (which includes,a $0.56 rate adjustment charge collected by the City of Renton to make up for the billing methodology used by King County) for treatment and disposal. For other uses, including multi-family and commercial entities, the wastewater treatment charges are based on the volume of wastewater discharged with a minimum monthly charge equal to the single-family connection charge. For sewer service outside of the City, Renton has set a special rate class for non-resident customers. This rate is one and one-half(1 1/2) times the basic City sewer rate applicable to resident users for similar service. Said additional charges are to cover costs of planning, franchising, permitting, and operation through other jurisdictions. 8.3.2 Charges The City's policy is to pay for the expansion of the sewer system through future connection charges or system development charges (SDCs). The City's share of the total CIP charges for the years 2008 through 2012 were divided into development charges and major maintenance costs (as shown in Table 8.10). These development charges were added to the existing system development charges to establish the development charges for the future system. This cost was then evenly distributed amongst the equivalent residential unit (ERU) of the entire future system (in the year 2012) to establish the SDC as shown in Table 8.5. Using this method, the base SDC charge is $1,591. Table 8.6 shows the allocation of the SDC charges based on meter size. In addition to the SDC assessed by the City of Renton, King County also assesses a capacity charge to King County residences connected to the system after February 1st 1990. This charge is billed directly to the residence by King County. Currently single-family Final 2010 8-2 King County residences are charged $46.25 per month for 15 years. King County establishes the capacity charge annually and the revised capacity charges apply only to new connections.

The number of staff, and the additional staff positions for Wastewater have been identified in Chapter 7. For purposes of this financial analysis, recommended staffing levels for operating the wastewater utility were predicted to be reached within this plan's six-year period in order to keep pace with anticipated growth. Inflation for labor is estimated to be 3 percent annually while the inflation rate for benefits is estimated at 7 percent as summarized in Table 8.1. For purposes of the financial analysis, the estimated revenue requirements for the next six years (2008 through 2013) were based on the 2008 operating budget with additions for planned new services and inflation. Table 8.9 summarizes these estimated costs. Final 2010 8-7 Table 8.9 Estimated Future Operation Costs Long-Range Wastewater Management Plan City of Renton Year Estimated Operation Cost 2008 $15,629,000 2009 $18,522,000 2010 $19,563,000 2011 $20,845,000 2012 $21,660,000 2013 $22,379,000 Total $118,597,000 8.4.1.2 Capital The recommended CIP presented in this LRWWMP consists of improvements necessary to serve the projected service area's population 2028 at the lowest reasonable cost. The project costs listed here are intended for budgetary purposes only, because they are based on current construction costs and should be adjusted for actual inflation depending upon the actual construction date. The costs for all of the improvements have been estimated, based on current information available. It should be reiterated that changes in system flow rates, system growth, financial policies, and regulatory requirements all contribute to adjustments in long-range planning. We recommend that financial goals be evaluated every five years, and that a detailed cash flow analysis be conducted annually. Table 8.6 presents the estimated costs of the capital improvement program as recommended in this Comprehensive Plan. Table 8.10 summarizes the six-year CIP as presented in Chapter 6. The yearly rates for single-family residences presented in Table 8.11 were calculated by adding the yearly CIP costs to the anticipated yearly operations costs and dividing that by the anticipated yearly ERUs. 8.4.2 King County The 2008 King County charges are summarized in Table 8.4. King County's 2008 charges are a flat monthly fee of$27.95 for each single-family residential connection. For other uses, King County charges $27.95 per month for each 750 cf with a minimum monthly charge of$27.95.

The City adds a rate adjustment charge, currently $0.56 per single family and per 750 cubic feet for other users. This charge allows the City to collect the additional costs associated with the billing methodology contained within the contract between the City and King County for wastewater treatment services. 8.4.3 Revenue Sources 8.4.3.1 Bonds Two types of bonds are available as sources of revenue: general obligation and revenue. The City has the authority to levy a tax (subject to a vote of the people) that could be used to pay principal and interest costs of a.general obligation bond issue. The City has not used this means of revenue generation for the wastewater utility and does not plan to unless a serious disaster occurs that requires massive improvements and/or replacements beyond the City's ability to fund it through other sources. Revenue bonds are issued and sold by the City when large amounts of money are needed to build general purpose capital improvements that benefit the City as a whole. The City, like other municipalities, is capable of issuing tax-exempt bonds. The principal and interest payments for such bonds are repaid from general revenues, connection charges, assessments and interest earned on investments. In order to qualify to sell revenue bonds, the City must show that its net operating income (gross income less expenses) is equal to Final 2010 8-11 or greater than 1.3 times the annual principal and interest due for all outstanding bonded indebtedness. The 1.3 factor is commonly referred to as the "coverage factor." 8.4.3.2 Loans The public works trust fund is the primary loan used to fund CIP projects. These are low- interest rate loans are available from the state for replacement of existing sewer system facilities. Interest rates vary from a low of 0.5 percent to a high of 2 percent depending upon the City's matching share. It is emphasized that these low interest rate loans are for replacements only and cannot be used for accommodating growth. These loans can be utilized effectively for replacements in the Central Business District (CBD) and other fully developed areas of the City's service area. This includes areas that are currently developed on private septic systems. 8.4.3.3 Grants Both the federal and state and centennial clean water fund are funding sources available to the City. Federal and state loan and grant programs are available for wastewater capital improvement projects. These programs are primarily designed to fund improvements that upgrade wastewater treatment facilities in order to comply with Federal Clean Water Act (PL92-500). With budget cutbacks at both the federal and state level, the possibility of receiving government funding for a portion of the recommended improvements at this time is remote. Should additional funds be made available, the City should explore the feasibility of obtaining funds from these sources. The Centennial Clean Water Fund is an example of state grant funding, which is currently available. This grant fund's highest priority is to eliminate public health emergencies and secondly, to improve water quality. The City should continue to pursue these funds for projects that meet its criterion. 8.4.3.4 King County King County funds are available for the construction of interceptors and local service extensions if the investment can be justified. Currently King County limits its investment to projects where the amortized capital cost of the project can be recovered through King County fees collected from the residential customer, or equivalent, that are served by the extension at the time of project completion. 8.4.3.5 Local Improvement Districts LID assessment income is paid to the City from assessments levied against specific properties that have benefited from improvements in a defined area. Typically, Local Improvements District's (LIDs) are formed by the City at the written request (by petition) of property owners within a specific area of the.City. Upon receipt of a sufficient number of Final 2010 8-12 signatures on petitions, a local improvement area is defined and improvements are designed for it. Each separate property in the LID is assessed in accordance with the special benefits the property receives from the sewer system improvements. Generally, it is the policy of the City to assess the benefited properties 100 percent of the cost of the improvements plus the general facilities and sewer connection charges. LID projects may be divided into two categories. 1. Improvements of Local Interest: If necessary, specific problems, such as excessive septic tank failures, can be corrected through an LID. If not necessary, these projects can be postponed until a later date when the area needs or desires it. 2. Improvements of Regional Interest: These projects are beneficial to an area larger than an LID and are initiated by the City. While LID funding would help, the project is of such importance that a lack of LID should not delay it. If an LID cannot be formed, additional funding from other sources (including the City) may be necessary. 8.4.3.6 Developers City policy requires that all developers/property owners take financial responsibility for the necessary improvements before their development benefits from them. This responsibility may be satisfied in one of the following ways. In all cases, developer/property owners should be required to pay for the costs to the extent their property benefits from the facility installed (their fair share). 1. Utilities Installed: If the utilities necessary are already installed, the developer/property owner will reimburse the party (city or private) that installed the facility through a latecomer agreement or special assessment district, where such agreements exist. 2. Utilities Not Installed: If the utilities necessary are not installed, then the developer/property owner must extend or make improvements to the facilities following routes that comply with the City's Comprehensive Sewer Plan. If the plan is not definitive for that area, then the facilities will be extended and installed in a manner that best serves the City of Renton's citizens as determined by the Wastewater Utility Engineer. If the facilities installed potentially benefit other properties, a latecomer's agreement may be requested. If the facility required by the City is determined by City Council to be significantly more expensive because of oversizing or routing requirements, then the Council may agree that the City participate. If a City capital improvement project is being planned, designed, or constructed, developer/property owners could choose to participate financially in the City's project rather than make the improvements themselves. Final 2010 8-13 8.4.3.7 Others This category of funding responsibility is primarily for participation by other municipalities, such as adjacent cities or districts. Negotiations need to be accomplished to finalize funding responsibilities before annual adjustments to the CIP and rate increases. 1. Contingency Revenue Plan: If the funding from other sources does not happen as anticipated, or on the schedule anticipated, then the City should adjust this plan's CIP. Alternative adjustments available to the City are as follows: a. Reduce the scope and magnitude of the improvements with corresponding reductions in cost, b. Defer that portion of the improvements necessary forthe benefit of others until the funding is obtained, c. Proceed with the CIP as recommended in this plan and finance the other beneficiary's share with the provision that these other costs should be recovered including interest costs. It is critical to the implementation of the CIP that these funds are obtained from other funding sources. The level of funding from other sources is based on the current perceived degree of benefit from each project; this may change based on the actual degree of benefit assessed at the time the project is planned to begin. 8.5 SUMMARY Over the next six years, the City is anticipating spending approximately $22,370,000 on capital projects and $118,596,549 on operations and maintenance costs. Based on these costs, the City is anticipating that the single-family residential rate will increase from $15.55 per month to $18.55 by the year 2013, an increase of approximately 20 percent over six years.

Under date of August 11th, 1970, the City and Safecare- Careage entered into the Safecare-Careage Contract which permitted Safecare-Careage to build the Springbrook Line hereinabove defined. • . (2•), Said contract provided for reimbursement to Safecare- •C?reag•e, subject to the laws and ordinances .of theCity of Renton, by the owner.of real:.estate who did not.contribute to the orig-. inal, cost of :the :imp rovement. and:.w o. suhsequtntiy<..wished to tap. into';or. hook :onto or use the ..facilities. (3.'),. . Said contract also reserves to the City the right .;to make or cause to be made extensions of or additions to the above-mentioned improvement and to allow service connections to be made to said extensions oradditions without liability on .the part of the City. (4•) The properties, the owners of which are to be charged for tapping into or hooking onto the Springbrook Line, and the amount • and. rate, of said charges for said properties, have already been determined in accordance with Ordinance No. 2847 of the City of Renton. , Ofthe properties involved in this Agreement, they are the properties, sewer service to which is to be provided by the City_ and not by the District under this Agreement. (5Y') • The City is presently providing sewer service to Lots 1 and ,2 of Scott's Terrace by means of the existing crossing. z. , .(6.) Noformalagreement-for the provision of sewer service lathe subject area has been entered into between the City and ,the District. The City also-proposes to provide sewer service to Lots 4 and S of Scott's Terrace by permitting the construction of the proposed crossing. (8•) The City is prepared to furnish sewer service through the Springbrook Line to Lots -3, 6,• 7 and .8 of Scott's Terrace. ��,•.) .,,. .Although all of Scott's Terrace and the •Radovich Property are within the Cascade Sewer District and are outside the limits of the City, each party recognizes that sewer service .to Lots 1, 2, 3, 4, 5, 6, 7, 8 and 16 of Scott's Terrace and to that portion -3- of the Radovich property which lies to the west of the southerly prolongation,of the westerly boundary of Lots 17 ' : • - and 18 of Scott's Terrace can be provided by the City through the Talbot Road Line sooner than such service could be pro- vided by the District, and that sewer service to thtse prop- erties by the City elk' the payment to the City of the' charges necessary under the Safecare-Careaie Contract as already de- termined pursuant to said Ordinance No. 2847 has and will pro- vide the funds for reimbursement of Safecare-Careage under the contract. (10.) The District proposes to serve the properties within - U.L.I.D. 11 by-utilizing the existing crossing and thd proposed • ° crossing as hereinabove defined. (11.) Both the City and the District have identical—agree- ments with METRO relating to the METRO.

(6.) Without any cost to the City, the District Will Place a 11111164 at the easterly end of the ‘existing crossing and will connect the 'exiting side-sewer to this inanhole. The •.,District will also cause a manhole to be, constructed at the easterly end of the proposed crossing, and each of said manholes, when cOmpleted, will be transferred to the City to own as part of their main extensions consisting of the existing cros- sing and the proposed crossing. Said manholes will meet the design and construction requirements of the .city. - . (7.) Unless it has the prior consent of the City, the . District will not attempt to make sewer service available to • those properties lying immediately south of So. 180th Street • and in the immediate vicinity of the Sringbrook Line which, without the construction of main extensions which would be exempt from any charges under Paragraph S of the Safetare- Careage Contract, can be served by that portion of the Spring- brook Line as presently constructed. (8.) Although portions of the lines hereinabove described will be jointly used by the City and the District, each of the parties hereto will maintain its own lines at its own cost. (9.) If all of the properties which are to be served by • the District under this Agreement are annexed to and become a part of the City, the District will, without charge to the City, transfer to the City the entire sewer system to be con- structed by the District in U.L.I.D. 11 as described in this Agreement. (10.) All facilities constructed by the District which are to be transferred to the City under this Agreement will be transferred by an appropriate Bill of Sale in standard form. (11.) The District will hold the City harmless from any -6- I) claims made against the City and will protect the City from any liabilities in connection with any of the work to be done by the £i strict. (12.) Nothing in this Agreement as to which party shall pro- vide sewer service toparticular properties shall be construed as to require the provision of such service except in accord- ance with the Ordinances or Resolutions of the party, and upon payment to the party of all proper charges by the property owner. IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their duly authorized officers and to have their respective seals affixed hereunto.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done)and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most ( precise information known,or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer,or if a question does not apply to your proposal,write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems,the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. • USE OF CHECKLIST FOR NONPROJECT PROPOSALS: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS(part D). . For nonproject actions (actions involving decisions on policies, plans and programs), the references in the checklist to the words "project," "applicant," and "property or site" should be read as "proposal," "proposer,"and"affected geographic area," respectively. • A. BACKGROUND 1. Name of proposed project, if applicable: City of Renton 2008 Long-Range Wastewater Management Plan 2. Name of applicant: City of Renton-Wastewater Utility 3.

Agency requesting checklist: City of Renton 6. Proposed timing or schedule(including phasing,if applicable): The 2008 Long-Range Wastewater Management Plan addresses the policies, criteria, and recommendations needed to construct, maintain, and manage a wastewater utility for full land use development (saturation) under current comprehensive land use plans. That level of development will likely occur by the year 2040. This Long-Range Wastewater Management Plan will be adopted in early 2009. It will be further supplemented or updated on a regular basis or more often if needed. 7. Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? If yes,explain. Yes, the City plans to supplement or update the Long-Range Wastewater Management Plan on a regular basis or more often if needed. This study recommends that the plan be updated in 2014. 8. List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. Each of the projects identified by this plan is subject to SEPA regulations. Depending on the scope of project, each will have its own environmental checklist and determination which would be completed as specific projects are proposed for construction. 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes,explain. Several individual projects within the area covered by this proposal are pending SEPA approval. -2- • • 10. List any governmental approvals or permits that will be needed for your proposal, if known. The 2008 Long-Range Wastewater Management Plan will need to be approved by the Renton City Council and the Washington State Department of Ecology. The King County Utilities Technical Review Committee (UTRC) will review the plan and make recommendations to the Executive and County Council as to the consistency of such items with adopted county policies and codes. King County will review and approve franchises to allow the construction of sewer facilities in county rights-of-way. 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. The 2008 Long-Range Wastewater Management Plan addresses policies, criteria, assumptions and recommendations for the City's planning area. The major purpose of the Plan Is to provide a long range plan for facility improvements necessary to serve the estimated population at saturation. The Plan addresses facility reliability, public health, groundwater and environmental protection, operation and maintenance, and financing Issues. The plan also addresses the need to expand Renton's sewer service area into Its Urban Growth Area as the appropriate provider of the urban service per the King County Countywide Planning Policies. This checklist does not address the specific projects addressed in the five year capital improvement program. This is a programmatic checklist and does not address any site specific conditions. These conditions as well as the associated impacts will be discussed in the SEPA reviews of each project. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The area covered by this comprehensive sewer system plan is the sewer service area as shown In Figure 2.3. Renton has entered into boundary agreements with most of the sewer service providers adjacent to the City. These service boundaries are established and are not generally altered by annexations. B. ENVIRONMENTAL ELEMENTS 1. EARTH a. General description of the site (circle one); fiat, rolling, hilly, steep slopes, mountainous, other The forces of glaciation during the last million years fundamentally shaped the geologic characteristics of the proposed service area's natural landscape. As the glaciers advanced and retreated,they deposited, compressed,and leveled the soils that formed the plateau areas to the east and west of the City, gouged out Lake Washington, and the wide, flat flood plain of the Green River Valley, and determined the original routes of the Cedar River, Green River, and May Creek. The modern result is several water courses with narrow to wide flood plains adjacent to steep banks up to rolling hilly plateaus. -3- • b. What Is the steepest slope on the site(approximate percent slope?) The proposed service area contains numerous slopes within the ranges of 15-25%, 25-40%,and greater than 40%,as a result of glacial scouring. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. In general, soil types are classified according to mineral composition, topography, biological activities within the soil, climate, and the length of time of soil development. The following description of four soil types (or associations) existing in the Renton area is based on the U.S. Soil Conservation Service's soil survey for King County. The Soils Map shows the four types found in the Renton area. These types are the Alderwood Association, the Orldia-Seattle-Woodinville Association, the Beausite-Alderwood Association, and the Everett Association. (Community Profile: Oct., 1989) d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Many of the major valleys and shoreline bluffs in the proposed service area are bordered by steeply sloping unconsolidated glacial deposits that are highly susceptible torn gravity sliding. e. Describe the purpose, type,and approximate quantities of any filling or grading proposed. Indicate source of fill. We do not anticipate that any of the projects Identified in this plan will require grading or filling of a site. When backfilling the trench, we will use native material • (that which was removed during excavation) if it meets standards. If the native material is not of an appropriate quality, we will import backfill from an approved source. Any imported backfill material will be addressed in the environmental review during project specific planning phases. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Minor erosion may result during construction of program projects. Standard erosion control measures will minimize any impact from the minor erosion. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Program projects may rarely directly create impervious surfaces. Typically,sewers are installed In asphalt roadways or on easements where structures are prohibited. h. Proposed measures to reduce or control erosion,or other impacts to the earth, if any: When projects are developed, pursuant to this comprehensive plan, the construction of those projects will meet all erosion control requirements as set forth in the City's adoption of the King County Surface Water Manual, King County Erosion Standards,or additionally be required by a SEPA finding. -4- 2. AIR a. What types of emissions to the air would result from the proposal (i.e,, dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any,generally describe and give approximate quantities if known. Potential vehicular and equipment emissions may affect the ambient air quality for a short period of time during construction of program projects. These impacts would be addressed in environmental review during project specific planning phases. b. Are there any off-site sources of emission or odor that may affect your proposal? If so, generally describe. Potential vehicular emissions may result during the ongoing maintenance functions of the system by City staff. All City vehicles must meet Sate emissions control requirements including bi-annual emissions tests. c. Proposed measures to reduce or control emissions or other impacts to air,if any: When projects are developed, pursuant to the Long-Range Wastewater Management Plan, the construction of those projects will meet all City or County codes including emissions control. 3. WATER a. Surface Water: 1) is there any surface water body on or in the immediate vicinity of the site (including year- round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate,state what stream or river it flows into. Yes. The northwest boundary of the City Is the shoreline of Lake Washington. There are several streams and rivers in the area. In the northern portion of the proposed service area there is May Creek, a Class 2 stream (with salmonids) which flows into Lake Washington. There are several unclassified streams that flow into May Creek. Maplewood Creek flows from the East Renton Plateau to the Cedar River. The lower portion of Maplewood Creekis a Class 2 stream (with salmonids). The upper portions are unclassified. A short run of Madsen Creek, a Class 2 stream (with salmonids), enters the proposed service area prior to entering the Cedar River. The Cedar River is a class 1 stream that flows through the Middle of the proposed service area and discharges into Lake Washington. In addition to the class 2 streams mentioned above,there are several unclassified streams that flow into the Cedar from the East Plateau portion of the the service area. Panther Creek is a Class 2 stream (with salmonids). There are a couple of unclassified streams that flow into it in the service area. Panther creek is a tributary to Springbrook Creek -5- Springbrook Creek is a.Class 2 stream (with salmonids) as it flows north through Renton. As it crosses north under Grady Way it becomes a class 1 stream. Springbrook is pumped into the Green River, which eventually flows into Puget Sound. There are numerous wetlands in the identified sewer service area. Some of the . projects identified in this plan may be in the vicinity of these wetlands. These projects will address this issue in the SEPA review of the individual projects. All City or County codes, as well as any outside agency requirements, will be met as provided in the SEPA finding. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Any projects identified within this document that are within 200 feet of the described waters will address the issue in the SEPA and Shoreline Permit Review of the individual project. All City or County codes, as well as any outside agency requirements,will be met as provided in the SEPA finding. It is the Wastewater Utility's goal to avoid construction in or around wetlands. It is, however, not beyond the scope of possibility that we will have to work on lines existing in the vicinity of wetlands or that engineering constraints may leave us few options for new construction. If work is required in or around wetlands, we will address this issue in the SEPA review for that specific project. Reasonable effort will be made to maintain the integrity of, restore, or replace all wetlands areas as required by State and local regulations. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. Any fill and dredge material that may be placed in or removed from surface water or wetlands will be addressed in the SEPA review of the individual project. All City or County codes, as well as any outside agency requirements, will be met as provided in the SEPA finding. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose,and approximate quantities if known. We do not anticipate that there will be any discharge to or withdrawal from surface water. The Sewer Comprehensive Plan proposes elimination of on-site sewage disposal systems that could cause discharge of contaminated waters to surface waters in the event a failure occurs. 5) Does the proposal lie within a 100-year flood plain? If so, note location on the site plan. • Within the proposed service area there are 100-year flood plains along several streams, including but not limited to Cedar River, May Creek, and Springbrook Creek. Portions of specific projects may be located within a 100-year flood plain. These projects will address this issue in the SEPA review of the individual projects. All City or County codes, as well as any outside agency requirements, will be met as provided in the SEPA finding. -6- • 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. Any potential discharge of waste materials to surface waters will be addressed in the SEPA review of the individual project. All City or County codes, as well as any outside agency requirements,will be met as provided in the SEPA finding. b. Ground Water: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. • We do not anticipate that there will be any discharge to or withdrawal from ground water. The Sewer Comprehensive Plan proposes elimination of on-site sewage disposal systems that could cause discharge of contaminated waters to ground waters in the event a failure occurs. The study also proposes design and construction standards for use in the Aquifer Protection Areas. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals...; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s)are expected to serve. This study proposes guidelines and projects that will result in the reduction of discharges into the ground water by reducing the potential failure of Renton's sewer system, and allowing for elimination of septic systems. This will be a beneficial impact of this Plan. Any potential discharge of waste materials into the ground will be addressed in the SEPA review of the individual project. All City or County codes,as well as any outside agency requirements,will be met as provided in the SEPA finding. c. Water Runoff(including storm water): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any(include quantities, if known). Where will this water flow? Will this water flow into other waters, If so, describe. There will be no runoff that can be directly attributed to the adoption of this Comprehensive Plan or any completed project as described within. Any runoff that may occur during construction of the capital improvement projects will be subject to City or County codes, as well as any outside agency requirements provided In the SEPA finding. 2) Could waste material enter ground or surface waters? if so,generally describe. No discharge of waste materials to ground or surface waters will result from the adoption of this Comprehensive Plan. The Plan discusses and proposes design and construction policies in the Aquifer Protection Areas as well as proposing a sanitary sewer system that will allow for the elimination of on-site sewage disposal systems that may be allowing the discharge of contaminated material to surface or ground waters. -7- d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: Proposed measures to reduce or control surface,ground,and runoff water impacts will be addressed the SEPA review of the individual project. Ail City or County codes, as well as any outside agency requirements, will be met as provided in the SEPA finding. 4. PLANTS a. Check or circle types of vegetation found on the site: X deciduous tree:alder, maple,aspen,other X evergreen tree:fir, cedar, pine,other X shrubs X grass X pasture crop or grain X wet soil plants:cattail, buttercup,bullrush)skunk cabbage, other X water plants:water lily,eel grass,milfoil,other X other types of vegetation b. What kind and amount of vegetation will be removed or altered? It is expected that localized Impacts to vegetation could occur as a result of clearing to accommodate construction of projected facilities. Any potential removal or alteration of vegetation will be addressed In the SEPA review of the individual project. All City or County codes will be followed and any necessary removal will be mitigated at the time of application. c. List threatened or endangered species known to be on or near the site. It is currently unknown If threatened or endangered flora exists within the study area. If there are threatened or endangered species Identified on or near the site of any Individual project discussed within this Plan, the impacts will be considered and discussed during the SEPA review of that project. d. Proposed landscaping, use of native plants, or other, measures to preserve or enhance • vegetation on the site, if any: Any potential landscaping, use of native plants, or other measures to preserve or enhance vegetation on site will be addressed in the SEPA review of the individual project. -8- 5. ANIMALS a. Circle any birds and animals which have been observed on or near the site or are known to be on or near the site: A wide variety of birds and animals native to the Puget Sound Lowlands are found within the study area. The more common are underlined below: Threatened or endangered species will be avoided, relocated or replaced wherever possible. Birds: hawk, heron, eagle,songbirds, other Mammals:deer, bear,elk,beaver, other Fish:bass,salmon,trout,herring,shellfish,other b. List any threatened or endangered species known to be on or near the site. Protected species such as the bald eagle have been observed within the study area. It is not expected that the proposed program would adversely impact these species over the long term. Short'term construction related impacts may occur. These impacts would be discussed in the SEPA review of the specific project and avoided wherever possible. c. Is the site part of a migration route? If so,explain Yes. The Cedar River is a fish migration route used by Chinook, Coho and Sockeye Salmon; and Steelhead and Searun Cutthroat Trout. The Catalog of Washington Streams and Salmon Utilization contends that "for its size, the Cedar River in this section supports one of the largest populations of salmon in the State". As identified in the May Creek Current and Future Conditions Report(August 1995), May Creek and some of it tributaries support five species of salmonids, including Chinook, Coho,Sockeye,Steelhead,and Cutthroat Trout. The entire State of Washington is included within the Pacific flyway migration route. We do not anticipate any project within this plan having any major, long term impacts on migration routes. d. Proposed measures to preserve or enhance wildlife, if any: Any potential measures to preserve or enhance wildlife will be addressed in the SEPA review of the individual project. All City or County codes, as well as any outside agency requirements,will be met as provided in the SEPA finding. -9- 6. ENERGY AND NATURAL RESOURCES a. What kinds of energy(electric, natural gas,oil, wood stove,solar)will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing,etc. Some facilities, such as lift stations, will require electrical energy in order to run the pumps and telemetry. We also use gas powered emergency generators to power stations in case of an electrical failure. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. None of the proposed project facilities would cast shadows affecting adjacent or surrounding properties. c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any: All facilities will be constructed utilizing efficient energy use systems that will not effect safety or reliability. Whenever the option is available, sewage lift stations will be eliminated and gravity sewers constructed to reduce the electrical power consumption of the system. 7. ENVIRONMENTAL HEALTH a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so,describe. There are no environmental health hazards directly associated with the adoption of this Comprehensive Plan. This Plan will have a beneficial impact by helping to reduce environmental health hazards by making sanitary sewer service available to • land uses that generate pollutants. Renton's wastewater collection system, like any other, has the potential of spill or environmental health hazard because of failure due to lack of funding or personnel to maintain or replace the system as needed. This Plan documents and proposes policy and procedures to minimize the potential of a health hazard. The system is also susceptible to catastrophic events such as earthquakes. We cannot plan against them, if the ground moves significantly the line will rupture. The Comprehensive Plan recommends that the City Wastewater Utility prepares an Emergency Response Plan. 1) Describe special emergency services that might be required. The Wastewater Utility's Maintenance Division and City's Emergency Services Departments are on call, 24 hour a day, to address any emergencies that may occur. _1Q_ • 2) Proposed measures to reduce or control environmental health hazards, if any: This document details policy and design criteria, such as policies for the design or elimination of lift station, and design loading or design period of our sewer facilities, intended to reduce this possibility to the absolute minimum. b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment,operation, other)? Existing noise Is not anticipated to affect construction or operation of projects proposed in this plan. 2) What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. There will not be any noise involved with the adoption of this Comprehensive Plan. The projects Identified in this PIan will have short term noise impacts associated with their construction. After they are put into operation, lift stations will generate minimal levels of noise. Underground stations would be muffled by the ground so as to be practically silent while above-ground stations will have a hum that would be quieter than the noise of an arterial such as Sunset Blvd.or Main Avenue. 3) Proposed measures to reduce or control noise impacts, if any: When projects are developed pursuant to this Comprehensive Plan, the construction of those projects will meet all City or County codes including those regulating noise. 8. LAND AND SHORELINE USE a. What is the current use of the site and adjacent properties? Current land uses within the area of this study vary from heavy industrial to single family residential to vacant. b. Has the site been used for agriculture? If so,describe. Many portions of this study area have a history of agricultural uses. Any projects Identified within this document that may be In an area once used for agriculture will address this Issue in the SEPA review of the individual project. All City or County codes, as well as any outside agency requirements, will be met as provided in the SEPA finding. c. Describe any structures on the site. Structures vary throughout the project are from residential to industrial. This includes single family, multi-family, commercial, retail, office, light manufacturing { and heavy manufacturing. -11- d. Will any structures be demolished? if so,what? When eliminating or replacing a lift station, the structure housing the station may • be demolished. Demolition of any other structures for or during the construction of any the identified projects is not anticipated. if a structure must be demolished, it will be addressed in the SEPA review of the individual project. Compensation and relocation, if necessary, would be addressed in project specific documentation. All City or County codes, as well as any outside agency requirements,will be met as provided in the SEPA finding. e. What is the current zoning classification of the site? The Comprehensive Plan covers all areas of the City and involves all zoning within the City code. Current zoning varies depending upon the specific location of individual projects within the comprehensive planning area. f. What is the current comprehensive plan designation of the site? The 2004 City of Renton Comprehensive Plan (as ammended) designates land use within the City limits. The remainder of the program planning area, which is in unincorporated King County, uses the 1994 King County Comprehensive Plan (as ammended) to designate land use. All of the study area in unincorporated King County is designate "urban". Three Community Plans, New Castle (1988), Soos Creek (1991), and West Hill (1994) were used as additional information in the County areas. g. If applicable,what is the current shoreline master program designation of the site? Some of the projects identified within this document are in areas identified in the Shoreline Master Program for the City of Renton. Any of the projects within these areas will be addressed in the SEPA review of the individual project. All City or County codes, as well as any outside agency requirements,will be met as provided in the SEPA finding. h. Has any part of the site been classified as an "environmentally sensitive" area? If so, specify. Some of the projects identified within this document are in areas that may be classified as "environmentally sensitive" in categories such as soils, slopes, and wetlands These projects will be addressed in the SEPA review of the individual project to determine the alternative with the least environmental impact. All City or County codes, as well as any outside agency requirements, will be met as provided in the SEPA finding. Approximately how many people would reside or work in the completed project? Presently,the City of Renton Sanitary Sewer System services approximately 11,000 customer accounts (domestic and commercial). This study addresses sewer needs for full (saturation) development under current Comprehensive Land Use Plans. When the study area identified in this Plan is fully developed (under current land use) and the necessary sewer system is in place, we project approximately 20,000 customers. -12- j. Approximately how many people would the completed project displace? It is not anticipated that any projects identified within this Plan would displace anyone within the project area. k. Proposed measures to avoid or reduce displacement Impacts, if any: Does not apply. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans,if any: This proposed Comprehensive Sewer System Plan was prepared to be consistent with the City's and County's Comprehensive Land Use Plans and with the comprehensive sewer system plans of each adjacent municipality. The Wastewater Utility will maintain coordination with the City's Land Use Comp Plan by updating or amending our Plan as needed. To ensure compatibility the Plan will be reviewed by all applicable State agencies and adjacent utilities. 9. HOUSING a. Approximately how many units would be provided, if any? Indicate whether high, middle, or low-income housing. No housing units will be provided as a result of the adoption of this Comprehensive Plan. This Plan addresses the development of the sewer system needed for land uses under the current (2004) City Land Use Plan. Any housing units constructed concurrently or subsequently to projects identified in this study will be per adopted City of Renton Land Use Plans and Polices. The specific projects identified within this Plan will be designed to handle the capacity proposed in the Land Use Comp Plan current at that time. Sewer capacity is but one factor in the growth of the housing supply. Development should be per the Land Use Plan and not until all facilities (i.e., water, emergency services, schools, transportation) are in place. Therefore, no significant impact on housing will result from these projects. b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle,or(ow-income housing. We do not anticipate the elimination of any units by either the adoption of this Plan or any subsequent projects. c. Proposed measures to reduce or control housing impacts, if any: Neither the adoption of this Plan nor any of the projects talked about within this document will have any direct impacts on local or regional housing supply. None of the projects are of a scope that would require bringing large numbers of workers to the area for construction or operation. 10. AESTHETICS a. What is the tallest height of any proposed structure(s), not including antennas;what is the principal exterior building material(s) proposed. -13- Some of the projects identified within this study will include sewage pumping stations which may include above ground electrical panel enclosures (up to six feet tall), small permanent buildings (up to twenty-five feet tall) or under a freestanding canopied(carport type)structure. b. What views in the immediate vicinity would be altered or obstructed?

Do not use this sheet for project actions.) Because these questions are very general, it may be helpful to read them in conjunction with the list of the elements of the environment. When answering these questions, be aware of the extent the proposal, or the types of activities likely to result from the proposal,would affect the item at a greater intensity or at a faster rate than if the proposal were not implemented. Respond briefly and in general terms. 1. How would the proposal be likely to increase discharge to water; emissions to air; production,storage,or release of toxic or hazardous substances;or production of noise? This Comprehensive Sewer Plan is a long range proposal and documentation of operation policy, design criteria, and recommended facility improvements. it will be used as a guide in maintaining and improving the system. When we construct any of the proposed rehabilitation or replacements, there will be the potential of discharge to the environment,as we connect or bypass active lines. This potential is minor, however, when compared to the probable impact a neglected and deteriorating facility would have. A sewer system that is properly designed, constructed, and maintained should have, during it's useful life, a minimal likelihood to discharge to water; emissions to air; production, storage, or release of toxic or hazardous substances. While we can not eliminate natural disaster or human error impacts to the system, following proper engineering, construction and maintenance practices, as identified in this plan,should minimize the potential of impacts. • If there is a spill or discharge, the City will follow Department of Ecology cleanup and reporting guidelines. Proposed measure to avoid or reduce such increases are: This study proposes guidelines and specific projects that will reduce the possibility of release of toxic or hazardous substances by reducing the potential of failure of Renton's sewer system, and allowing for the elimination of septic systems. 2. How would the proposal be likely to affect plants,animals,fish,or marine life? • Adoption of this Plan will not directly affect plants, animals, fish or marine life. However, there will be the potential of indirect impacts as projects identified within the plan are constructed. Those impacted were discussed in Sections B.4 and B.5 of this checklist. Proposed measure to protect or conserve plants, animals, fish,or marine life are: Any projects identified within this document that may affect plants, animals, fish, or marine life will address this issued in the SEPA review of the individual project. • -18- Any threatened or endangered species of plants will be avoided, relocated, or replaced wherever possible. It is not expected that the proposed program would have any long term impact of animals or fish. All City or County codes, as well as any outside agency requirements,will be met as provided in the SEPA finding. 3. How would the proposal be likely to deplete energy or natural resources? It is not anticipated that the adoption of this Plan or the construction of any projects identified within will have any significant Impact on the depletion of energy or natural resources. (See Section B.6 of this checklist.) Proposed measures to protect or conserve energy and natural resources are: Many projects identified in this study will remove sewage pumping stations in favor of gravity systems and thus reduce the utilities energy consumption. All City or County codes, as well as any outside agency requirements, will be met as provided in the SEPA finding. 4. How would the proposal be likely to use or affect environmentally sensitive areas or areas designated (or eligible or under study) for governmental protection; such as parks, wilderness, wild and scenic rivers, threatened or endangered species habitat, historic or cultural sites,wetlands,floodplains,or prime farmlands? The Wastewater Utility is creating this Comprehensive Plan to identify, document, and propose policies for the maintenance and construction of our sewer system in a manner that is consistent with the public health and water quality objectives of the State of Washington as well as the goals set by the City and County to protect environmentally sensitive areas. It Is the Wastewater Utility's Intent to strike a balance where we avoid environmentally sensitive areas where feasible; prevent or reduce the maintenance or deterioration of our system; and eliminate septic systems where they pose a potential threat to the environment. (See Sections B.1, B.3 and B.8 of this checklist). Proposed measures to protect such resources or to avoid or reduce impacts are: Construction of the new facilities as well as the redevelopment of existing facilities will be accomplished in a manner to protect environmentally sensitive areas and with measures to mitigate any potential impacts. These will be addressed on a project by project basis,as appropriate,when they are submitted for SEPA review. 5. How would the proposal be likely to affect land and shoreline use, including whether it would allow or encourage land or shoreline uses incompatible with existing plans? The City's adopted Land Use Plan was reviewed to ensure that this Comprehensive Sewer System Plan would be compatible with land and shoreline use. The development of new facilities and redevelopment of existing facilities will be accomplished in a manner to avoid or reduce shoreline and land use impacts where feasible and still maintain the purpose of a sewer utility. This Plan and the projects identified within it are not sensitive enough to land use as to allow or disallow uses that are incompatible with existing Plans. We supply sewer service (urban services) to areas designated urban as per State requirements. How the land or shoreline is used is determined by the Land Use Plan. _f9_ Proposed measures to avoid or reduce shoreline and land use impacts are: Construction of the new facilities as well as the redevelopment of existing facilities will be accomplished in a manner to avoid or reduce shoreline and land use impacts and with measures to mitigate any potential impacts. These will be addressed on a project by project basis, as appropriate, when they are submitted for SEPA review. 6. How would the proposal be likely to increase demands on transportation or public services and utilities? This Comprehensive Sewer System Plan provides a guideline to help accommodate the increased demand for sewer service that the City has been and is expected to continue providing as the City develops. This Plan addresses the demands on the sewer system based on adopted Comprehensive and Land Use Plans and will not increase demands on transportation or public services and utilities. The projects identified within this Plan will be phased by priority per the criteria set forth in the Plan with emphasis put on the rehabilitation and replacement of existing systems; aquifer protection; and removal of lift stations. There will be times when the minimum size pipe needed will have more capacity available than desired or when the most efficient use of funds is to put in a larger line, designed for the build-out of the basin, when a smaller line will be adequate in resolving the current problem. The excess sewer capacity itself will not increase the demand of other public services. Any subsequent development that has an impact on public services will have to provide the additional services to satisfy the demand. Proposed measures to reduce or respond to such demand(s)are: This Plan addresses the increased demand put on the sewer utility by development in and around the City and what is foreseen as development occurs per the current adopted Land Use Plan. As the Land Use Plan is updated, the Sanitary Sewer Comp Plan will also be updated. 7. Identify, if possible, whether the proposal may conflict with local, state or federal laws or requirements for the protection of the environment. This Plan is In accordance with all local, State and Federal law and requirements for the protection of the environment. C.

It is based on the City's sewer system as it existed as of January 2008. This plan will be used as a guide in maintaining and improving the sanitary sewer system over the next six years in order to provide the Renton Sewer Service Area with an effective, safe and reliable sewer system. While this plan is an update to the 1998 Long-Range Wastewater Management Plan adopted in 1999; it is a re-evaluation of the entire sanitary sewer system and a stand-alone document, not a supplement. A summary of this plan's findings and recommendations are presented in this chapter. The plan results from an evaluation of the existing sanitary sewer system and recommendations to resolve existing deficiencies and concerns, and to accommodate growth. The improvements identified in this plan are based on the requirements of the Washington State Department of Health, Washington State Department of Ecology, King County Comprehensive Plan, and City Comprehensive Plan. The City's Comprehensive Plan is the overall guidance for future growth within the City of Renton. This long-range wastewater management plan is an element of the City's Comprehensive Plan. The Renton sanitary sewer system is large, and because of the topography, complex in its operation. The condition of the current system, as well as the need for improvements, has been documented in this report. Due to the complexity of this system and the number of issues that must be addressed, this report is organized so that a reader may review a summary of it and its recommendations in this chapter without reading the background or detailed information that led to those results. The plan provides a recognized framework for making decisions about Renton's sanitary sewer service area, which includes properties both inside and outside the City limits. It is intended to aid decision-makers as well as users, including the Wastewater Utility, City Council members, the Mayor and staff, builders, developers, community groups, and other government agencies. The plan will be a useful tool in the following ways: As a framework for improvements and operations that govern sanitary sewer system developments in the Renton Wastewater Utility service area. The plan provides a basis for allocating improvements and costs to new sanitary sewer system users such as home and apartment builders, and commercial developers. It thus provides • officials with partial direction for approving building permits and upgrading the system. • REVIEW DRAFT- January 2009 1-1 • To provide a guideline for improving the existing system so that each customer receives adequate sanitary sewer service. It is intended that City officials be able to use these guidelines to maintain a high quality of service at a reasonable cost. • To provide a basis for accommodating changes that occur but that cannot be forecast in the plan. To this end, the plan lists policy issues and operational criteria that can be used to develop alternatives and directions for development, improvements, and operations. 1.2 SCOPE OF STUDY The scope of study includes the following: • Coordinate plan with adjacent utility systems and identify areas for potential service area boundary adjustments. • Document City policies regarding growth and service areas. • Estimate wastewater flow rates using land use designations. • Analyze the existing system to determine its deficiencies and needed improvements. • Prepare a Capital Improvement Program and estimate its construction costs. • Document, in summary form, the existing operations and maintenance program and recommend improvements and staff additions. • Analyze the recent financial performance of the sewer utility and develop a financial operating projection statement. This plan is arranged in eight major sections: • Chapter I provides a summary of the recommendations and conclusions presented in this plan. • Chapter II provides a general overview of the existing sewer system and a definition of terms. • Chapter III presents specific policies that guide the operation of the sewer.system. • Chapter IV examines the land use policies that guide how the City accommodates growth and presents the land uses, joint use agreements and design criteria that were used to develop wastewater saturation flow rates on which the computer hydraulic analysis was based. • Chapter V describes and analyzes all components in the existing system and presents their recommended improvements. REVIEW DRAFT-January 2009 1-2 • Chapter VI further describes the improvements necessary to resolve existing deficiencies and accommodate growth. The proposed improvements are also listed by priority and by project type. • Chapter VII examines the operation and maintenance programs for the Wastewater Utility. • Chapter VIII presents the costs of the proposed improvements and the anticipated user increases that will be necessary to support them. t3 PLAN REQUIREMENTS This update to the Plan is inspired by the need to provide constant evaluation of our sewer system and operating policies in order to meet the needs of the customers and to ensure compatibility with the City and County's Comprehensive plans. This updated plan is prepared in conformance with Chapter 173-240 of the Washington Administrative Code (WAC), which requires that a plan include the following information shown in Table 1.1.

This system consists of approximately 191 miles of gravity sewer, 23 sewage lift stations and force mains, and approximately 5,107 manholes. Wastewater is discharged to King County facilities at 79 locations within the City Service Area from which it is conveyed to and treated by King County's South Treatment Reclamation Plant. The City of Renton Service Area is divided into six major wastewater collection basins: Black River, Downtown, East Cedar River, East Lake Washington, May Valley, and West Cedar River. For the most part, these major collection basins follow the natural drainage patterns of the Renton service area. For the purposes of monitoring and.modeling the sanitary sewer system, the major collection basins are divided into one or more model basins. King County developed 11-model basin for the Renton service area as part of its Infiltration and Inflow Program. Each model basin is the area tributary to the downstream location where the City and King County used meters to collect flow data during the 2000/2001 and 2001/2002 flow monitoring seasons for King County's Infiltration and Inflow Program. This flow data was used for the creation and calibration of the City's hydraulic • sewer model developed by Roth Hill and used in this Plan. 1.5 POLICIES AND DESIGN CRITERIA Policies, design criteria, and standards used for planning and operating the sanitary sewer system are based on laws and policies that originate from several sources. All these policies and standards have the general purpose of providing an acceptable level of service to the sanitary sewer customers. Policies presented in this plan include the following: customer service policies, financial policies, facility policies, and organizational policies. Analysis and design criteria for the sanitary sewer system are based on standards presented in the Criteria for Sewage Works Design prepared by the Washington State Department of Ecology as well as standards set by King County Department of Natural Resources -Wastewater Treatment Division and the City of Renton. 1.6 PLANNING CONSIDERATIONS The City of Renton Wastewater Utility has a service area that encompasses a wide variety of residential, commercial, and industrial land uses over 13,484 acres. There are several adjacent utility systems surrounding the City's existing service area, which limit the expansion of the City's sewer system. The greatest potential for expansion of the City's sanitary sewer system is within the May Valley, Skyway and East Renton areas that currently either do not have existing or adequate sanitary sewer facilities. Future sewer system requirements are based upon growth projections within the established sewer service area, derived from the Renton Traffic Analysis Zone (RTAZ) REVIEW DRAFT-January 2009 1-4 projections. In addition to the RTAZ projections, future planning data for areas outside the current City boundaries was based on Traffic Analysis Zone (TAZ)data obtained from the Puget Sound Regional Council (PSRC). Based on these sources the residential population within the service area is expected to grow from 44,504 in 2001 to 102,901 by the ultimate saturation year, which represents a growth of approximately 230 percent. The ultimate saturation year is anticipated to be after 2030. The commercial population is excepted to grow from 49,128 in 2001 to 103,357 at ultimate saturation representing a growth of 210 percent. Wastewater flow generation was modeled based on an assumed domestic generation of 100 gals/d-person while infiltration and inflow(Ill) is modeled at 1,500 gallons per acre per day(gpad). Peak storms were assumed to increase the flow rate by a factor of 2 to 1. 1.7 KEY ISSUES This plan addresses the following key issues: • The need and timing of the replacement of older, deteriorating sanitary sewer facilities within large, neighborhood, size areas of the City. • The evaluation of Renton's facilities for system capacity, to address both system deficiencies and potential development within Renton's sewer service area. • The evaluation of sanitary sewer lift stations for removal, rehabilitation and replacement. • The City's Ill program in coordination with the overall King County program to evaluate option and needs for Ill reduction. • Review of industrial waste and grease discharges to the sewer system and the need for monitoring and coordination with the public to eliminate problems that potentially lead to sewer overflows. Some of these issues were also addressed during preparations of the 1992 and 1998 Long-Range Wastewater Management Plans. 1.8 SYSTEM ANALYSIS A hydraulic and a structural analysis were conducted to determine how well the existing system achieved current policies and technical, engineering standards. The plan identifies where the system failed to meet those objectives and recommends improvements to the existing system or construction of new facilities to achieve them. A hydraulic analysis was performed by a computer simulation of the existing system to determine its ability to convey wastewater at saturation flow rates. The Wastewater Utility's computer model was used to analyze the system and to size future facilities. This model REVIEW DRAFT- January 2009 1-5 was updated in 2006 using the MOUSE software program. The software platform was chosen to be consistent with the software platform used by King County regional infiltration and inflow study. The model was calibrated to the year 2001 and then expanded for the 2030 ultimate buildout condition. This computer model will continue to be used by the City as an analytical, planning and management tool. A structural analysis, which is a visual inspection of the existing system, was also conducted and was based on video, as well as actual, physical inspections. Based on the hydraulic model analysis,flow projections were developed for each mini-basin. Between 2001 and the ultimate buildout, peak flows increased by an average of 1.6 times for each mini-basin. However, seven of the 53 basins • actually experienced a decrease in flow with the highest decrease for the ultimate year modeled at 45 percent of the 2001 flow. Additionally, the model projected that for a couple of the mini-basins, the flow increase would be considerably higher than average, with the largest modeled ultimate peak flow increase being 7.65 times greater than the 2001 condition. The analysis revealed deficiencies that cover a broad range of areas. The hydraulic deficiencies identified are inadequate slopes (inability to achieve carrying velocities), insufficient capacity to handle wastewater flow rates, pipes that are less than 8-inches in diameter and sections that have reverse slopes. Structural deficiencies identified are pipe sag, and root and grease problems. The Renton sewer system has these hydraulic and structural problems in varying degrees throughout the system. 1.9 SEPA AND APPROVAL PROCESS A SEPA Checklist has been prepared for this plan and is presented in Appendix C. It is anticipated that this proposed plan will not have a probable significant adverse impact on the environment and that an environmental impact statement(EIS)will not be required. However, many of the projects proposed herein will require SEPA checklists and an engineering determination will be made with each individual project. This plan includes review by adjacent utility systems. All comments are include in Appendix D. 1.10 CONCLUSIONS AND RECOMMENDATIONS In the development of this plan, the following conclusions were reached: 1. A substantial percentage of the system has reached or is reaching the end of its useful life and needs to be replaced. The projects of highest concern are: a. Several system wide projects including: miscellaneous sewer projects and emergency repairs, Earlington sanitary sewer replacements, Renton Central Business District sewer replacement, Renton Hill sanitary sewer replacement. REVIEW DRAFT-January 2009 1-6 b. Two projects in the West Cedar River Basin: Heather Downs/Maplewood interceptor improvement and the Falcon Ridge lift station rehabilitation. c. Several projects in the East Cedar River Basin including: the Central Plateau interceptor, East Cedar River collection sewers, Evendell lift station elimination, East Renton lift station elimination and the Highlands Estates lift station elimination. d. Several projects in the Lake Washington East Basin including: Stonegate/Summerwind flow diversion, the Duval interceptor, the Westview lift station replacement/rehabilitation, the Sierra Heights sewer system construction and the Lake Washington Beach lift station rehabilitation. e. Three projects in the Black River Basin including: the Thunder Hill interceptor replacement, the SW 34th street interceptor replacement and the Lind Avenue lift station rehabilitation. f. Several projects in the Downtown Basin including: Earlington lift station elimination, the Shattuck Ave S. interceptor downsizing, the Renton Center sewer extension, the Airport lift station rehabilitation and the North Earlington collection system. g. Two projects in the May Valley Basin including: the Misty Cove/Baxter lift station replacement, and the Denny's lift station rehabilitation. 2. Continue development of the gravity sewer system in order to allow the elimination of existing sewage lift stations. These lift stations are less reliable, require higher maintenance and operations costs and cause more adverse impacts to downstream facilities than do properly planned gravity sewer systems. 3. Rehabilitate or replace the sewage lift stations that are considered to be permanent sewage facilities. These improvements will reduce maintenance costs and increase system reliability. As the City rehabilitates or replaces regional stations, on-site emergency power generators should be installed. 4. The City needs to continue to update its hydraulic model to reflect the new adopted land use designations and concurrency standards, changes in development patterns, system changes, and as data becomes more current. The City should continue the model update by completing the inventory of the sewer system, verifying the as-built records and gathering data on those parts of the system that are not recorded. 5. The City should implement a flow monitoring program to meter flows in order to gather data to calibrate the sanitary sewer computer model. This will enable the model to be more closely calibrated in areas of concern. The City will continue to use the sewer model to develop a schedule of timing for capacity system improvement projects. As the County looks to implement 10-year cycle flow monitoring, the City should look at potential saving by partnering in the monitoring. REVIEW DRAFT-January 2009 1-7 6. The City needs to establish a grease and industrial waste discharge program for the Wastewater Utility. Grease is the leading cause of sewer overflows in our system. Industrial waste poses a serious risk to our sewer maintenance personnel. 7. The City needs to evaluate capacity restraints, analyzing them from both the potential of increasing capacity and reducing 1/I within the basins that facilities serve. Where reduction in Ill is at a similar cost of upsizing facilities, serious consideration shall be • given to the I/I alternative. 8. Where the City annexes an area that is currently unsewered by another municipality, the City should provide sewer service. Where annexation occurs andsewer service is provided by another municipality, the City should determine whether to purchase the facilities from the adjacent municipality, or to continue to allow the existing agency to provide service. Purchase of facilities should be based on the actual depreciated cost the municipality incurred from providing the facilities to obtain service. 9. The rate increases recommended in this plan should be considered an estimate to implement the City-funded portion of all the recommended improvements. Currently, new development pays a major portion of the remaining cost of recommended improvements. If funding from this source, such as the System Development Charge or Special Assessment District Charges, are not available, the City's share of these construction costs will most likely increase. it should also be recognized that this plan does not establish annual Capital Improvement Programs (CIPs) or sewer rates, but rather provides a roadmap and guideline for the operation of the system.Yearly CIPs and sewer rates are established as part of the budget process. The City should update the financial models in a manner consistent with the City's budget schedule, so that rates can be adopted to accurately reflect the current financial situation within the utility. These models were developed as part of the 2006/2007 Rate Study undertaken at the same time this plan is being updated (Comprehensive Rate Study, Water, Wastewater, and Surface Water Utilities, Financial Consulting Solutions Group, Inc., 2006/07). 10. This plan should be updated at intervals of no greater than six years in order to accommodate unforeseen changes in existing assumptions, conditions and land Use designations, and for adjusting budgets and sewer service rates.

K.C.C. chapter 13.24 requires approval of comprehensive plans for 5 sewer utilities as a prerequisite to granting right-of-way franchises and 6 approval for right-of-way construction permits. Such plans or their 7 updates must be submitted to the county at least once every six years, and 8 more frequently if circumstances call for an earlier submittal. 9 2. K.C.C. 13.24.060 requires that such plans be consistent with the 10 requirements of any comprehensive plans or development regulations 11 adopted under chapter 36.70A RCW or any other applicable 12 comprehensive plan,land use plan or development regulation adopted by a 13 city,town,or county for the service area. The King County 14 Comprehensive Plan,which includes wastewater policies in its provisions 15 for facilities and services(policies F-245 through F-254),also calls for 16 consistency with other adopted plans,support for regional water supply 17 planning,pursuit of reclaimed water and water conservation and. 18 protection of water resources. 1 Ordinance 17015 19 3. Both Washington state Department of Ecology("DOE")and King 20 County regulations require sewer plan approval prior to construction of 21 new facilities. 22 4. The city of Renton("the city")provides sewer service to a population. 23 of over forty-four thousand and an employment base of forty-nine 24 thousand. Its service area includes the entire city and a small part of 25 unincorporated King County. The service area is a mixture of residential, 26 commercial,and light industrial,and includes portions of park and open 27 spaces. The city's facilities discharge to the regional wastewater system 28 operated by King County. 29 5. The city's service area has recently expanded with annexations and 30 includes areas without sewer service. Its anticipated growth through 2030 31 will be largely mixed-use development and redevelopment construction. 32 In addition,the city expects to accommodate additional flows as a result of 33 providing sewers to a portion of its service area that does not currently 34 have service. By 2030,it expects to be serving a residential population of 35 approximately one hundred two thousand nine hundred one people as a 36 result of both growth and annexations. 37 6. The principal operational issues in the plan are the need for and timing 38 of the replacement of older,deteriorating sanitary facilities in the city and 39 extending service to areas without sewer service. The city is cooperating 40 with the county to investigate the origins and magnitude of excessive 41 infiltration and inflow into the sewer system from different portions of its 2 Ordinance 17015 42 service area. The city anticipates working with the county to develop a 43 strategy for reducing those flows as part of the regional infiltration and 44 inflow program. 45 7. The county's most recent approval of the city's sewer plan occurred in 46 January 2000. 47 8. The King County utilities technical review committee("UTRC") 48 reviewed the city's plan("the plan")in December 2009. K.C.C.chapter 49 13.24 requires review of wastewater plans by the UTRC,and a 50 recommendation to the King County executive and council on the plan 51 and its consistency with the King County Code and Comprehensive Plan. 52 The planning data and proposed operations were reviewed by the UTRC, 53 and the plan was found to be consistent with: 54 a. the population and employment forecasts and growth targets developed 55 for the service area; 56 b. King County land use classifications;and 57 c. pertinent county adopted plans and policies. 58 9. The UTRC also found that,with revisions and additional information • 59 supplied by the city,the plan sufficiently addresses the specific issues 60 required to be addressed under K.C.C. 13.24.010.H.,including 61 opportunities for the use of reclaimed water. The UTRC recommends that 62 the King County council approve the plan. 63 10. The DOE has not yet reviewed and/or approved the plan as consistent 64 with RCW 90.48.110 and chapter 173-240 WAC. 3 Ordinance 17015 65 11. The city completed a state Environmental Policy Act checklist and 66 issued a determination of nonsignificance for the issuance of the plan on 67 April 24,2009. There was no appeal of the determination. 68 BE IT ORDAINED BY THE COUNCIL OF KING COUNTY: 69 SECTION 1.

One area of possible service overlap with Renton is identified south of 55th/SE 192nd in an area designated Urban Separator (see page 4-14). The info provided by Renton in Table 4.2 (p. 4-12) also has the maximum density for that single-family residential at 3 to 8 dwelling units per acre. The land is currently zoned at 1 dwelling unit per acre - in conformity with the Urban Separator Comprehensive Plan Land Use Map designation. 2. The most recent reference to the Kent Sewer Plan is from 1980 (also p. 4- 14). Merrill Vesper in our Public Works Department should be able to assist in refreshing the reference date. As they may have been anticipating a comment period closure in May, Merrill and other Public Works staff might require additional time to consider the Wastewater Plan in sufficient detail.

Renton,WA 98057 • Dear Mr.Benoit: • We received your letter and copy of the City of Renton's.(City) 2008 Long Range Wastewater Management Plan(Plan). You have submitted the Plan to King County's Utilities Technical Review Committee(UTRC)for approval by King County. Within King County,the UTRC evaluates the Plan for consistency.with the King County Comprehensive Plan and King County Code(KCC)prior to making a recommendation to the King County Council for Plan approval. The UTRC consistency review of the Plan includes: KCC 13.24.010(C)-Only plans consistent with the King County Comprehensive Plan adopted in KCC Title 20and corresponding development regulations shall be approved. The infrastructure system for the existing service area and for the area anticipated to be served in the future shall be based on the adopted land use map of the Comprehensive Plan. KCC 13.24.010(P)—Water and sewer comprehensive plans shall include information sufficient to demonstrate the ability to provide service consistent with the requirements of all applicable statutes,codes,-rules, and regulations. KCC 13.24.010(H)—Provides that sewer comprehensive plans shall be consistent with Washington Administrative Code(WAC) 173-240-050 and the plan shall discuss the following: • Existing and planned flows,both average and peak; • Existing and planned flows for any basin discharging into King County's sewage conveyance and treatment system; Amounts of inflow and infiltration(III)to the system,'a'comparison of those " . . amounts with.King County's.1,100 gallons-peracre-per-day.(gpad)standard, ., and steps being taken-to reduce the I/I;- •- , - .

Opportunities-for reclaimedrwater as required.under Revised Code:of' -• • Washington(RCW)'90.48:112 and RCW 90.48.495.' :. . . • . . The UTRC makes the following series of observations or statements related to our code ' responsibilities for plan review. At the end of the letter we summarize the issues that must be resolved for the UTRC to recommend approval of the Plan to the King County Council. In • general,the document was well written, easy to follow, and we thank you for that. Section 4.3.3—the first paragraph of this section pertains to King County land use and we offer • several suggested edits. First,the 2004 King County Comprehensive Plan with 2006 Amendments was replaced by_the King County Comprehensive Plan 2008, effective October 2008. The 2008 version is the current Comprehensive plan in effect. Secondly,the first paragraph briefly talks about sewer service to the rural area and the paragraph correctly notes that the potential annexation area for the City abuts the urban growth boundary and references policy F-249. The last sentence of the paragraph says, "The City will address the need(s)for expansion into the rural area as they arise." Extension of sewer into the rural area would not be a unilateral decision by the City,so please edit that sentence to include the concept of consistency with the King County Comprehensive Plan;which does not permit sewer service to the rural area except for public schools and failed septic systems when no cost efficient .- alternative is possible. We tend to agree withyour statement in the same paragraph that says,' •the City does not see the narrowly defined situations whet:sewer service is allowed to rural areas as a major impact to the City's proposed service area. .• . . ' .• . . . ..•. Finally,the last paragraph of section 4.3.3—talks about King County land use and states, "Unincorporated areas of King County are divided into community planning areas, each with a community plan. While these community plans were not adopted as part of the 1994 King County Comprehensive Plan,the policies of community plans that are consistent with the comprehensive plan remain in effect and continue as official County Policy." The community C plans are adopted as part of the King County Comprehensive Plan 2008, effective October 2008, so please edit accordingly.- • Section 4.3.6.2 states the Cedar River Water&Sewer District's last Comprehensive Sewer 0 Plan was adopted in 1994. I believe their last plan was adopted in 2006. • • Section 4.3.7 refers to aquifer protection ordinances and we just want to affirm that for those areas outside the City and within unincorporated King County, the critical areas ordinance and critical aquifer recharge area mapping corresponds(generally)to your zone 2 designation. Hence, our code and land use policies support protection of the aquifer used by the City. Section 4.4 is the demographic analysis and.it is not apparent from the text if the Plan considered the City's adopted Growth Management Planning Conncil's..(GMPC)population • and employment targets for the City and the potential annexation area(PAA): Did the City. compare the demographic data created for this Plan with your.adopted growth targets? If so, you may want to note that so it is clear the City's sewer service will accommodate the adopted fi Growth Management Act population and employment goals. • • Michael A Benoit December 17, 2009 Page 3 ' We note the discussion in 5.2.1 related to the King County Interceptor. As you noted, and we • affirm, King Countyhas.implemented several projects to kgnificantl3rincrease the-influent and • effluent capacity at South Plant and has'installed parallel interceptor facilities to reduce the chance of surcharging: hi addition to past projects,the County has planned additional projects • to ensure its obligations are satisfied with respect to the potential for Wastewater overflow in low-lying areas as part of the regional conveyance system.

We thank you for your past and continuing participation in the Regional I/I program. Peak flows by basin have been listed in table 5.1 for each mini basin used to estimate flows' generated in the Renton collection system dining storm events. There should be some discussion of how these peak 1/1 flows compare to the King County.1,100 gpad standard. The results of the initial I/I projects currently in design by King County Wastewater Treatment . Division, and scheduled for construction in 2011 and 2012,will provide additional information on 1/I removal efficiency. . • The Plan states the East Cedar River basin(section 5.3.2) and May Creek basin(section 5.3.6) are partially developed with subdivisions on private septic systems. That is not surprising given the generally rural character of the areas. We agree with your discussion of extension of • service to areas that are currently unsewered as the entire area is within the urban growth • • boundary and sewers are necessary to achieve the population targets set by the,GMPC. We • encourage the City to develop specific policies to encourage extension of sewer service to these Com► areas and how the City might support the utility local:improvement districts for that area east of . the City and within the PAA. . . Section 8.4.2 addresses current King County sewer charges. Those charges appear to be summarized in table 8.4 instead of the referenced table 8.3. As noted elsewhere in the Plan, the . charges by the county may change. Given this is a 2009 plan,perhaps the Plan could reference } 2009 charges which may be found on our website at http://www.kingcounty.gov/environment/wastewater/CapacityCharae.aspx • • The footnote to table 8:3 notes that sewer rates outside the City are 1.5times higher than within • I the City. Please provide a brief rational for the rate differential for that portion of the sewer service area not within the City. With respect to corrosion and odor control,.and steps being taken to reduce their occurrence, we note the Plan does not identify any problems. An evaluation of the opportunities for reclaimed water use as required under RCW 90.48.112 does not appear to have been done. To facilitate the assessment,the Washington State • Department of Ecology has published guidance material on their website. I want to - acknowledge that the City has participated with King County by•providing potential use data for use within our reclaimed water planning process and we thank you for that: Perhaps a brief note on that effort would be helpful within the Plan. • . . • . . - ..

In addition, and while not a sewer issue,the City's franchise 6030 for water expired last June.

We hope you find these comments helpful as you fnali7e the City's s Plan. We look forward to seeing the final Plan and working with you,to secure the King County Council approval. The Council's final action on the Plan will constitute King County's approval of the Plan.

PURPOSE OF PLAN The purpose of the Renton Comprehensive Sewer System Plan is to present policy and design criteria and to recommend facility improvements. This plan will be used as a guide in maintaining and improving the sanitary sewer system over the next five years in order to provide the residents of the City with an effective, safe and reliable sewer system. This plan is not an update to the Comprehensive Sewer Plan adopted in 1983; it is a complete re-evaluation of the entire sanitary sewer system. A summary of this plan's findings and recommendations are presented in this chapter. The plan results from a study that evaluated the existing sanitary sewer system and developed recommendations to resolve existing deficiencies and concerns,and to accommodate growth. The improvements identified in this plan are based on the requirements of the Washington State Department of Health, Washington State Department of Ecology and City Policy. The City of Renton adopted its last Comprehensive Sewer Plan in 1983. That plan anticipated growth in the system and proposed improvements but did not foresee all of the issues that have arisen since that time: 1) concerns for groundwater protection, 2) significant increases in construction cost, and 3) increases in land use densities. These issues and others are examined in detail in this Comprehensive Sewer System Plan. The Renton sanitary sewer system is large, and because of the topography, it is difficult to comprehend. The condition of the current system, as well as the need for improvements, has been documented in this report. Due to the complexity of this system and the number of issues that must be addressed, this report is organized so that a reader may review a summary of it and its recommendations in this chapter without reading the background or detailed information that led to those results. The plan provides a recognized framework for making decisions about sanitary sewer service in the City of Renton. It is,intended to aid decision makers .as well as users, including the Wastewater Utility,City Council members,the Mayor and staff,builders,developers, community groups, and other government agencies. The plan will be a useful tool in the following ways: • As a framework for improvements and operations that govern sanitary sewer system developments in the City's service area. The plan provides a basis for allocating improvements and costs to new sanitary sewer system users such as home and apartment builders, and commercial developers. It thus provides City officials with partial direction for approving building permits and upgrading the system. 1-1 CHAPTER ONE • To provide a guideline for improving the existing system so that each customer receives adequate sanitary sewer service. It is intended that City officials be able to use these guidelines to maintain a high quality of service at a reasonable cost. • To provide a basis for accommodating changes that occur but that cannot be forecast in the plan. To this end, the plan lists policy issues and operational criteria that can be used to develop alternatives and directions for development, improvements and operations. Several members of the City staff have a detailed understanding of the City's sanitary sewer I system and have provided valuable input for this plan. Mr. Richard Anderson, Mr. Randall Parsons,Mr. Mike Benoit,Mr. David Christensen, Mr. Gary Morrison and Mr. Jack Crumley are thanked for their assistance. B. AUTHORIZATION On November 7, 1988, the City of Renton authorized RH2 Engineering, P. S., to prepare the update to the Comprehensive Sewer System Plan in conformance with the Chapter 173-240 WAC. C. SCOPE OF STUDY The scope of study includes the following: • Analyze the existing system to determine its deficiencies and needed improvements. • Document City Council policies regarding growth and annexation. • Coordinate plan with adjacent utility systems and identify areas for potential service area boundary adjustments. • Estimate wastewater flow rates using land use designations. • Prepare a Capital Improvement Program and estimate its construction costs. • Document, in summary form, the existing operations and maintenance program and recommend improvements and staff additions. • Analyze the recent financial performance of the sewer utility and develop a financial operating projection statement. 1-2 Summary and Introduction D. EXISTING SEWER SYSTEM The City of Renton owns, operates, and maintains its sanitary sewer system. This system consists of approximately 153 miles of gravity sewer, 23 sewage lift stations and force mains, and approximately 3000 manholes. Wastewater is discharged to METRO facilities at 55 locations within the City from which it is conveyed to and treated by METRO's Renton Treatment Plant. The existing sanitary sewer system is shown on FIGURE 1. The City of Renton is divided into six major wastewater collection basins, each of which consist of one or more subbasins. For the most part, these collections basins and subbasins follow the natural drainage patterns of the Renton service area. These wastewater collections basins are shown on FIGURE 1. E. POLICIES AND DESIGN CRITERIA Policies, design criteria, and standards used for planning and operating the sanitary sewer system are based on laws and policies which originate from several sources. All these policies and standards have the general purpose of providing an acceptable level of service to the sanitary sewer customers. Policies presented in this plan include the following: customer service policies, financial policies, facility policies, and organizational policies. Analysis and design criteria for the sanitary sewer system are based on standards presented in the "Criteria for Sewage Works Design" prepared by the Washington State Department of Ecology as well as standards set by the Municipality of Metropolitan Seattle (METRO) and the City of Renton. F. LAND USE AND ADJACENT SYSTEMS Land use proposed in the City's 1983 Comprehensive Land Use Plan was used to estimate wastewater flow rates at saturation conditions within the City. These saturation wastewater flow rates were used to analyze existing sewage facilities and to plan for the location and sizing of new sewage facilities. Existing land use designations are shown on FIGURE 6. There are several adjacent utility systems surrounding the City's existing service area,which limit the expansion of the City's sewer system. The greatest potential for expansion of the City's sanitary sewer system is within the MayCreek and East Renton areas which currently either do not have existing or adequate sanitary sewer facilities. The adjacent utility entities are shown on FIGURE 7. 1-3 CHAPTER ONE G. KEY ISSUES This plan addresses the following key issues: • Excessive infiltration and inflow. • Extension of sanitary sewer service areas. • Aquifer protection and exfiltration from sanitary sewers. • Sewer system deficiencies including hydraulic constraints, substandard facilities, and replacement of old pipes. • Annexation and sewer service outside City limits. Several of these issues were also addressed during preparations of the 1983 Comprehensive Sewer Plan. H. SYSTEM ANALYSIS A hydraulic and a structural analysis were conducted to determine how well the existing system achieved current policies and technical, engineering standards. The plan identifies where the system failed to meet those objectives and recommends improvements to the existing system or construction of new facilities to achieve them. A hydraulic analysis is a computer simulation of the existing system to determine its ability to convey wastewater saturation flow rates. A computer model was developed and used to analyze the system and to size future facilities. This computer model will continue.to be used by the City as an analytical, planning and management tool. A structural analysis, which is a visual inspection of the existing system, was also conducted and was based on video, as well as actual, physical inspections. The analysis revealed deficiencies that cover a broad range of areas. The hydraulic deficiencies identified are inadequate slopes (inability to achieve carrying velocities), insufficient capacity to handle wastewater flow rates,pipes that are less than 8-inches in diameter and sections that have reverse slopes. Structural deficiencies identified are pipe sag, and root and grease problems. The Renton sewer system has these hydraulic and structural problems in varying degrees throughout the system. I. SEPA A SEPA Checklist has been prepared for this plan and is presented in Appendix E. It is anticipated that this proposed plan will not have a probable significant adverse impact on the environment and that an environmental impact statement (EIS) will not be required. However, 1-4 Summary and Introduction many of the projects proposed herein will require SEPA checklists and some will require an environmental impact statements. J. CONCLUSIONS AND RECOMMENDATIONS In the development of this plan, the following conclusions were reached: 1. Two areas are seriously deficient in capacity: 1) the East Renton area, specifically the South Highlands, Maplewood, and Heather Downs Subbasins within it, currently has a moratorium on connections until capacity improvements have been made, and 2) the Honey Creek Subbasin within the May Creek Basin is at capacity and has some marginally reliable.facilities. 2. A substantial percentage of the system has reached the end of its useful life and needs to be replaced. These areas include the Downtown, North Renton and Highland areas. 3. The City needs to perform detailed testing to obtain better engineering information regarding the operation and hydraulic behavior of the system. Specifically, a detailed infiltration and inflow project should be performed as well as a video inspection to affirm this plan's evaluation and provide an improved basis for future planning. 4. Design and construction standards need to be modified for use in aquifer protection areas. We recommend that a zero leakage policy be adopted for sewers within the Downtown and Maplewood aquifers. A specific example of an extremely high water quality risk is METRO's Cedar River Interceptor sewer which currently traverses through.the Downtown aquifer. We recommend that this sewer be relocated so that a failure or leakage is manageable, and contamination of the City's sole source aquifer is avoided. However, a zero leakage policy requires a special type of construction which would substantially increase costs over standard construction costs. 5. We recommend that the City adopt the following policy regarding extension of sewer service; where the City annexes an area that is currently unsewered by another municipality, the City should provide sewer service; where annexation occurs and sewer service is provided by another municipality, the City should purchase the facilities from the adjacent municipality, based on the actual depreciated cost the municipality incurred from providing the facilities to obtain service, so long as those facilities flow by gravity to the City system. 6. The rate increases recommended in this plan should be considered as the minimum level of increases necessary to implement the City-funded portion of the recommended improvements. Currently, new development pays a major portion 1-5 CHAPTER ONE of the remaining cost of recommended improvements. If funding from this source, such as the special utility.connecting fee, is not available, the City's share of these construction costs will most likely increase. 7. The City's sewer system is complicated; the preceding conclusions and recommendations are based on the highest priority issues, which, in our opinion, must be confronted. However, we propose a substantial number of additional recommended facility improvements and modifications which are further described in Chapter VI. When we assigned them priorities, we took into consideration the following characteristics: a. Whether a facility is structurally deteriorating or has hydraulic capacity problems. b. Whether an improvement increases overall efficiency by reducing operation and maintenance costs. c. Whether an improvement helps protect the environment or reduces a threat to public health. K. SYSTEM IMPROVEMENTS The following is a summary of proposed improvements to the Renton sanitary sewer system, presented in this Comprehensive Sewer System Plan, to correct existing facility deficiencies and to accommodate growth. 1. Adopt this Comprehensive Sewer System Plan in order to establish consistent City policies and to provide the capability of efficiently planning the sanitary sewer facility improvements. This plan should be updated at intervals of no greater than five years in order to accommodate unforeseen changes in existing assumptions and conditions, and for adjusting budgets and sewer service rates. 2. Replace aging and substandard sanitary sewer facilities within the City. These sewers present a significant potential danger to the environment and public health. 3. Continue development of the gravity sewer system in order to allow the elimination of existing sewage lift stations. These lift stations are less reliable, require higher maintenance and operation costs, and cause more adverse impacts to downstream facilities than do properly planned gravity sewer systems. 4. Rehabilitate or replace the sewage lift stations that are considered to be permanent sewage facilities. These improvements will reduce maintenance costs and increase system reliability. 1-6 Summary and Introduction 5. Examine programs and projects that will reduce wastewater flow rates and infiltration and inflow within the sanitary sewer system. These may be cost- effective methods that could possibly reduce thesize of sanitary sewer facilities, thereby reducing capital expenditures. 6. Implement sanitary sewer rate increases in order to finance capital improvement costs as well as operation and maintenance costs in accordancewith the utility rates study. L. IMPLEMENTATION In 1990 the Washington State Legislature, in recognition S of the need for growth management legislation to preserve the environment and quality of life while providing for economic growth, enacted the Growth Management Act (ESHB 2929). This act requires cities and counties in the populated regions of the state to develop coordinated Comprehensive Plans to identify areas where urban growth is appropriate, and to provide necessary transportation and utility improvements. The adoption of the Comprehensive Sewer System Plan is the first step that the Wastewater Utility is taking to implement the requirements of the Growth Management Act. The majority of this document presents information that will be used as a foundation as the City of Renton's Wastewater Utility plans for the future of the system. •This information includes 'a general overview of the existing sewer system and a definition of terms; a presentation of specific policies that guide the management and operation of the sewer system; an examination of the operation and maintenance programs for the utility; and a description and analysis of all components in the existing system with recommended improvements. These items are specific toward the effective and efficient operation of the utility. The first phase of the Comprehensive Sewer System Plan is a snapshot in time under current land use policies. It examines the current land use plan adopted in 1986, uses those designations to develop the saturation flow rates for the model, and establishes an operational plan to allow for the development of those land uses. It is important that this step be accomplished as nay loans or grants we receive will be based on this information. - As part of this process the Wastewater Utility's goal is to accomplish, pursuant to adoption of this plan, the following implementation tasks: A. Update the financial models developed in the rate management analysis (Water and Wastewater Rates Management Analysis, RH2 Engineering P.S, November 1989)during 1992,in a manner consistent with the City's budget schedule, so that rates can be adjusted to accurately reflect the current financial situation within the utility. B. Complete the inventory of the sewer system,,verifying the as-built records and gathering data on those parts of the system that are not recorded. 1-7 CHAPTER ONE. C. Develop and implement a program to meter flows in order to gather data to calibrate the sanitary sewer computer model. D. Use the sewer model to develop a timetable of availability for sewers in unsewered portions of the City and the Urban Growth Areas adopted by the City. E. Prepare an update to the 1991 Long-Range Wastewater Management Plan if necessary, to incorporate the new adopted land use designations F. Update the sewer model, if necessary, to reflect the new adopted land use designations and concurrency standards. M. HOW TO USE THIS PLAN This plan is arranged in eight major sections: Chapter I provides a summary of the recommendations and conclusions presented in this Comprehensive Sewer System Plan. Chapter II provides a general overview of the existing sewer system and a defmition of terms. Chapter III presents specific policies that guide the operation of the sewer system. Chapter IV. examines the land use policies that guide how the City of Renton accommodates growth; and presents the land uses,joint use agreements and design criteria that were used to develop wastewater saturation flow rates on which the computer hydraulic analysis was based. Chapter V describes and analyzes all components in the existing system and presents their recommended improvements. Chapter.VI further describes the improvements necessary to resolve existing deficiencies and accommodate growth. The proposed improvements are also listed by priority and by project type. Chapter VII examines the operation and maintenance programs for the Wastewater Utility. Chapter VIII presents the costs of the proposed improvements and the anticipated user increases which will be necessary to support them. 1-8 CHAPTER II OVERVIEW OF EXISTING SEWER SYSTEM CHAPTER II OVERVIEW OF EXISTING SEWER SYSTEM This chapter presents an overview of the existing sewer system. A more extensive description and analysis of the system, along with recommended improvements, can be found in Chapter 5. A. OVERVIEW OF EXISTING SYSTEM The City of Renton is approximately 16 square miles with a population of over 30,000. Approximately 70 percent of the land area and 80 percent of the population is currently served by sanitary sewers. The City of Renton's collection system is municipally owned, operated and maintained and is managed by the City of Renton's Planning/Building/Public Works Department (Public Works). The City maintains 23 sewage lift stations; an additional six sewage lift stations are privately owned and maintained. Wastewater is discharged to METRO facilities at 55 locations within the City, from which it is conveyed to and treated by METRO's Renton Treatment Plant. The City of Renton system contains approximately 3,000 manholes and 10,187 customer connections. FIGURES 1, 2 and 3 illustrate the existing sewer system in plan and profile views. B. SYSTEM HISTORY Sanitary sewer facilities were first constructed in the downtown area of the City of Renton in 1910. Prior to that it was common practice to dispose of wastewater on-site or to directly discharge it to the local estuaries. By 1940 the City's population had grown to 4,800;wastewater was collected and treated in a large septic system located adjacent to the Black River channel. During the 1940s,federal housing was constructed in the City to accommodate workers employed by defense industries. By 1956 the wastewater collection system served a.population of 14,800 people within the City's service area. By that time wastewater was treated in a secondary treatment plant located near the current Renton High School Stadium. This treatment plant discharged treated wastewater to the Cedar River. In 1958 the Municipality of Metropolitan Seattle (METRO) was formed to solve the growing problem of pollution in Puget Sound, Lake Washington and surrounding waters. METRO developed a regional plan for wastewater collection and treatment facilities in.1959 and assumed operating responsibilities for the regional interceptors and waste treatment systems in 1962, including Renton's secondary treatment plant. The new secondary treatment plant was constructed between 1956 and.1962 near the intersection of Grady Way and Monster Road and discharged into the Duwamish Water Way. This location is the current site of METRO's Renton Treatment Plant, which serves as one of the regional treatment facilities. The City of Renton sanitary sewers now discharge to these METRO facilities. 2-1 CHAPTER TWO C. SYSTEM COMPONENTS Thepurpose of a sanitary sewer is to convey wastewater from its source to a point of treatment. Since the generation of wastewater can vary considerably, there is seldom any control over the volume of wastewater that must be conveyed at any particular time. For this reason the sanitary sewer system is designed to accommodate a wide range of wastewater flow rates. The best method for conveying wastewater is a gravity sewer system. A gravity sewer system is made up of collector sewers, which as their name implies, collect the wastewater from the various sources. These collector sewers then convey the wastewater to interceptor sewers, which convey it to the point of treatment. The sanitary sewer system. must be capable of transporting all of the constituents of the wastewater stream, which include the suspended solids, floatable solids and liquid constituents. • Ingeneral, most of the floating materials are carried along with the flow stream; however, suspended solids have a tendency to settle out of the waste stream, unless minimum carrying velocities are achieved. This requires that the sanitary sewers be constructed with a minimum slope to create a gravity flow which will result in a velocity that will continuously carry the suspended solids portion of the waste stream. Another major sewer system component, and typically the most vulnerable one, is the sewage lift station. A lift station is needed when the sanitary sewer system must overcome topographic restrictions that make it impossible or financially unfeasible to construct a gravity sewer. However, some lift station are temporary, used only until the gravity sewer system can be built. D. WASTEWATER COLLECTION BASINS The City of Renton is divided into six major wastewater collection basins, as shown in FIGURE 1, which consist of one or more subbasins. These collection basins and subbasins predominantly follow the natural drainage patterns of the Renton service area. The six major basins are 1) May Creek, 2) Lower Cedar River, 3) Lake Washington East, 4) Black River, 5) Lake Washington West, and 6) Duwamish Estuary. E. INTERCEPTORS AND COLLECTION SYSTEMS Interceptors are sewers that receive flow from collector sewers and convey wastewater to a point for treatment or disposal. They are typically located in low lying or centralized areas in order to facilitate the gravity flow of the wastewater. The interceptors and all other sewers make up the collection system. Standards and guidelines for design and construction of sanitary sewers are detailed in Chapter 4. 2-2 Overview of Existing Sewer System The City of Renton has approximately 153 miles of gravity sewer within its service area as displayed in plan view in FIGURE 1. Sewers shown in bold represent the major interceptors in. the system: Those shown in gray represent the collection network. The sanitary sewer collection system is primarily comprised of 8-inch diameter sanitary sewers. The hydraulic profile, shown in FIGURE 2, illustrates how wastewater flows through the system. 1. EXISTING SEWERS The existing sanitary sewer system is constructed with a variety of different sewer sizes and pipe materials. TABLE II-1 summarizes the lengths of pipe for the different pipe diameters and Materials. As illustrated in this table, a majority of the sanitary sewer system is constructed with 8-inch diameter pipe. This is consistent with the Department of Ecology criteria material for minimum sanitary sewer sizing. The majority of pipe material within the existing system is comprised of concrete and PVC pipe. The concrete pipe has been typically used for the older sewers and larger diameter sewers, while the PVC pipe has been typically used for newer sewer system installations up to 12-inches in diameter. 2-3 CHAPTER TWO TABLE II-1: SUMMARY OF SANITARY SEWER SIZES AND PIPE MATERIAL PIPE SIZE SUMMARY PIPE DIAMETER LENGTH PERCENTAGE 6-inch 2.8 miles 1.8% 8-inch 93.5 miles 61.1% 10-inch 5.3 miles 3.5% 12-inch 7.8 miles 5.1% 14-inch 0.2 miles 0.1% 15-inch 2.4 miles 1.6% 16-inch 0.1 miles 0.1% 18-inch 2.2 miles 1.4% 21-inch 0.8 miles 0.5% 24-inch 1.5 miles 1.0% Unknown 36.4 miles 23.8% TOTALS 153 miles 100% PIPE MATERIAL SUMMARY PIPE MATERIAL LENGTH PERCENTAGE Concrete Pipe 64 miles 41.8% PVC Pipe 33 miles 21.6% Vitrified Clay Pipe 8 miles 5.2% Lined ductile iron pipe 5 miles 3.3% Unknown pipe type 43 miles 28.1% TOTALS 153 miles 100% The City sanitary sewer system also contains approximately 3,000 manholes, which join the various links of sanitary sewer pipe. These manholes vary in construction type from old brick manholes to the newer precast concrete manholes: Many of the older manholes do not meet current code for safety such as manhole covers which are less than 24-inches in diameter. 2-4 Si Overview of Existing Sewer System 2. INTERCEPTORS A list of the sanitary sewer interceptors within the Renton system is presented below. These interceptors are located in the following wastewater collection basins: MAY CREEK BASIN • Honey Creek Interceptor • Proposed May Valley Interceptor LOWER CEDAR RIVER BASIN • Tiffany Park Interceptor • South Highlands Interceptor • Maplewood Interceptor • Heather Downs Interceptor • Proposed Parker PUD Interceptor • Proposed East Renton Interceptor LAKE WASHINGTON EAST BASIN • Lakefront Force Main • West Kennydale Interceptor • North Highlands Interceptor • Proposed East Kennydale • Proposed Park Avenue BLACK RIVER BASIN • SW 16th Street Interceptor • Talbot Hill Interceptor • Springbrook Interceptor LAKE WASHINGTON WEST BASIN • West Renton Interceptor • Tobin Street Interceptor 2-5 CHAPTER TWO 3. METRO CONNECTIONS The Renton sanitary sewer system discharges wastewater to METRO sewer interceptors. at 55 locations. The wastewater flow rates into each of these connections varies considerably, depending on the area.served by the collection system. The major METRO connections for each subbasin are listed in TABLE II-2. TABLE II-2: MAJOR METRO CONNECTIONS SUBBASIN MANHOLE NO.

The City of Renton has 23 sewage lift stations within its sanitary sewer system. The location of these lift stations is shown in FIGURE 3. The most commonwet type is a well mounted lift station in which the mechanical and electrical equipment are located above the ground surface and over a large manhole out of which the wastewater is pumped. The second most common type is a wet well/dry well configuration in which mechanical and electrical equipment are located underground in a sealed enclosure adjacent to a large manhole from which the wastewater is pumped. Two other types of lift stations include a submersible pump installation in which the sewage pumps are placed directly in the wet well, and a pneumatic injector in which wastewater is conveyed through a force main using pressurized air. The City has one each of these types of lift stations. 2-6 Overview of Existing Sewer System Sewage lift stations are the most vulnerable element of a sewage collection system. Temporary lift stations are constructed when it is too costly, at that time, to complete the gravity sewer system; permanent lift stations are constructed when it is either physically impossible or financially impractical to construct gravity sewers. G. TELEMETRY AND CONTROL SYSTEM Successful operation of any municipal sewer system requires that the municipality maintain a comprehensive maintenance program and that they obtain accurate sewage flow rate information. Although many additional operation and construction elements are necessary for a complete and working system, maintenance and flow rate information are the keys to a successful operation. A telemetry and control system is the means by which flow rates are measured and maintenance needs are updated. The City currently owns and operates an analog, signal-based alarm reporting system, manufactured by Stead Baggerly of Bellevue,Washington,which monitors each lift station. The system includes a master console, located in the City Shops, and a remote telemetry transmitter located in each lift station. H. OPERATION AND MAINTENANCE The current operation and maintenance program for the sewer utility consists of four elements: normal operations,emergency operations,preventive maintenance and staffing. Normal operation of the sewer system is shared by the Engineering Division and the Operation and Maintenance Division. The program is described and evaluated in more detail in Chapter 7. I. DEFINITION OF TERMS Building Drain - In plumbing, that part of the lowest horizontal piping within a building that transports wastewater, or stormwater to a building sewer. Building Sewer - In plumbing, the extension from the building drain to the public sewer or other place of disposal. Also called house connection or private side sewer. Collector Sewer - A sewer that discharges into a main or trunk sewer and has no other common sewer tributary to it, only building sewers. Combined Sewer - A sewer intended to receive both wastewater and storm or surface water. 2-7 CHAPTER TWO Infiltration - Infiltration is the entrance of groundwater into the sanitary sewer system through cracks, pores, breaks, and defective joints in the sewer piping network. Inflow - Inflow refers to direct flow of stormwater into sanitary sewer systems through hookups from stormwater collection facilities and illegal connections. Interceptor Sewer - A sewer that receives flow from a number of trunk sewers and conducts such wastewater to a point for treatment or disposal. Lift Station - A sewage pumping facility which consists of a wet well for collecting wastewater;mechanical equipment such as pumps,valves and piping; electrical and control equipment; and a force main. Main or Trunk Sewer - The principal sewer to which collector sewers are tributary; also called trunk sewer. A sewer that receives many collector branches and serves a subbasin. Outfall - The point, location, or structure where wastewater or drainage discharges from a sewer, drain, or other conduit. Public Works - The City of Renton's Planning/Building/Public Works Department. Relief Sewer - 1) A sewer built to carry flows in excess of the capacity of an existing sewer. 2) A sewer intended to carry a portion of the flow from a basin in which the existing sewers are of insufficient capacity, and thus prevents overtaxing them. Sanitary Sewer - A sewer that carries liquid and waterborne wastes from residences, commercial buildings, industrial plants, and institutions, together with minor quantities of ground, storm, and surface waters that are not admitted intentionally. Separated Sewer - A sewer intended to receive only wastewater or stormwater or • surface water. Side Sewer - See building sewer. Side Sewer Stub - The portion of the public sewer between the collector sewer and the individual property line. 2-8 Overview of Existing Sewer System Storm Sewer - A sewer that caries stormwater and surface water, street wash and other wash waters, or drainage, but excludes domestic wastewater and industrial wastes. Also called storm drain. Wastewater - The spent or used water of a community or industry which contains dissolved and suspended contaminants which cannot be discharged directly to a lake, stream or river. Capacity Problems - When flow rates exceed what the facility is designed to convey. Gravity Sewer Capacity - The maximum capacity for a gravity sewer is the volume of flow that can be carried in a sewer at a depth to diameter ratio of 0.70 which is then used in the Manning's equation. Hydraulic Analysis - A computer simulation of a sewer system to determine if it can adequately convey saturation, wastewater flow rates. Lift Station Capacity - The maximum capacity for a lift station is equal to the peak, wet weather flow which the largest pump within the lift station has been designed to convey. Structural Analysis - A visual inspection, conducted by the human eye or by a video camera, to determine if any physical weaknesses or problems exist. Saturation Condition - The point at which development is complete within a land use designation. No further development is possible without a change in the land use limitations. 2-9 NORTH SOUTH FIGURE 2 CITY OF RENTON 500' HYDRAULIC PROFILE RENTON SEWER SYSTEM COMPREHENSIVE SEWER PLAN 475' SANITARY SEWER HYDRAULIC PROFILE 450` T'4 ct-�- =;•-777.771-- : \\\` e OCTOBER 30, 1990 PLOT SCALE 50 \\ FILE: SWRCMPS RH2 ENGINEERING P.S. �. - .-:,-- ---7.--77t."7:.••-:,-77-7'7'..77'. ..77:7"-'.

INTRODUCTION In addition to using flow rates and design criteria to analyze the existing system, each part of the system was evaluated against the specific policies that guide it. The policies, design criteria and standards used for planning and operating the sanitary sewer system are based on laws and policies that originate from the following seven sources, listed in descending order, from those with the broadest authority to the most narrow: • Federal Regulations - Environmental Protection Agency • State Regulations - Department of Ecology • METRO Policies - Municipality of Metropolitan Seattle • • City of Renton Ordinances - City Council • Administrative Policies - Mayor • Department Policies - Public Works Department • Utility Policies - Wastewater Utility Staff The laws and policies guide the wastewater utility's operations on a day to day basis, as well as its planning for growth and improvements. Their combined objective is to provide adequate, reliable sanitary sewer service at a minimum cost to the customer. The highest levels of policies--Federal Regulations, State Regulations;METRO policies, and City of Renton Ordinances--dictate requirements that are set by law. Other lower level policies cannot be less stringent or in conflict with those laws. The last three levels of policies, originating from the Office of the Mayor, Public Works Department, and Wastewater Utility Section, dictate requirements that supplement those laws. Those requirements are the specific policies summarized in this chapter. B. POLICIES The sewer system's ability to achieve the above laws, policies and standards is presented in - Chapter 5. Chapter 5 and 6 identify where the system fails to meet those requirements and recommends improvements. It is important to note that if standards are set too low, customers will not be satisfied, and if standards are set too high, the cost of installing and operating facilities to meet such standards will be financially unacceptable. 3-1 CHAPTER THREE All policies and standards have the combined purpose of providing an acceptable level of service to the sanitary sewer customers. Service, therefore, is the most important principle that guides construction, operation, maintenance and administration of the system. The following are components of the City's service policy: 1. Customer Service 2. Financial 3. Facilities 4. Organization The policies associated with each service category are identified in this chapter. TABLE III-1 illustrates the relationship between each of these categories. 1. CUSTOMER SERVICE POLICIES This section summarizes the customer service policies used to provide a connection to the sanitary sewer system. Annexations (Source: City Policy, State Law) • City annexation policies will not conflict with state regulations and guidelines. Renton will follow state guidelines in the assumption of facilities in annexation areas. • Areas annexed without existing municipal sanitary sewer service will be served by Renton. • Areas annexed with existing sanitary sewer service must meet Renton Sanitary Sewer Standards. • Service to areas outside of the city limits without annexation will be evaluated by the City Council on a case by case basis. The Public Works Department mandates design standards and criteria for the areas requesting service without annexation. • City Council will consider and may allow sanitary sewer service outside City limits under the following conditions: • A no protest agreement for annexation is signed by those obtaining service. -- 3-2 TABLE III—I: CITY OF RENTON WASTEWATER UTILITY POLICY OUTLINE CITY POLICY OUTLINE I 1 1 w CUSTOMER SERVICE FINANCIAL FACILITIESI ORGANIZATIONAL Co I 1 I I ANNEXATIONS COST OF SERVICE DESIGN CRITERIA STRUCTURE SERVICE INSIDE CITY RATES FOR OUTSIDE CITY MAINTENANCE LEVEL OF STAFFING TEMPORARY SERVICE LID'S/LATECOMER'S RELIABILITY RESPONSIBILITIES EMERGENCY SERVICE METRO CHARGES VULNERABILITY RELATIONSHIP WITH PLANNING BOUNDARIES JOINT USE OTHER DEPARTMENTS .% -1 imismimmilimimh viiimmom b0 co ti Q 0 2 b 0 ce' y CHAPTER THREE • Service is necessary to protect the City's drinking water supplies, or service is necessary to convert from a failing septic tank and drainfield, or the property served is within a drainage basin where service can be provided with gravity flow. • The full cost of service is paid by those served. • Boundary Review Board approval of service area boundaries is obtained. • City Council will consider annexations without assumption of existing sanitary sewer facilities under the following conditions: • The sanitary sewer facilities are operated and maintained by an adjacent municipal utility. • The adjacent utility has executed a service boundary agreement with the City. • The annexation area is located in a drainage basin that is better served by the adjacent utility. Mandatory Side-sewer Connections (Source: City Policy) • The City encourages all residents within the City to connect to public sewers. • Properties that are within two hundred feet of an existing sewer line which do not connect to it will be asked to pay a charge equal to the City's sewer charge. • Any party who has a connection available, but claims an exemption from using it, is required to provide proof to the City that its septic system works and that it periodically pumps and conducts follow-up tests on it. • Since failing septic systems pose a grave, health hazard to the City's groundwater, properties with such systems are required to connect to the public sewers. • The charge for failing to connect should be evaluated. • The City should research whether the low-income, infirm exemption applies to the hook-up charge and whether the City can financially assist people in that category. 3-4 Operational Policies • The City should reevaluate its policy on refusing to provide sewers outside of its limits when a threat to the City's aquifers exist. Temporary Services (Source: City Policy) • Compliance with standards may be deferred for temporary sanitary sewer service. Emergency Service (Source: City Policy) • Compliance with standards may be deferred for emergency sanitary sewer service. • Policy criteria may be waived for emergency service. Planning Boundaries (Source: City Policy) • • For planning purposes, the City will use sanitary sewer service boundaries established by agreement with adjacent municipalities. • Renton follows state law in assuming portions of adjacent sanitary sewer systems as a result of annexation. • Facilities will be planned and sized to serve natural basins to minimize the need for pumping. • Projected development and sewage flows will be based on adopted land use plans and policies. 2. FINANCIAL POLICIES This section details the financial policies to be used to operate the sanitary sewer system. Cost of Service (Source: City Policy) • The utilities will use a rate setting process that complies with standards established by the American Public Works Association. • Cost-based rates and additional charges established for the sanitary sewer utility are those that 1) recover current, historical, or future costs associated with Renton's sanitary sewer system and services, 2) are equitable charges to recover costs from utility customers commensurate with the benefits they receive, and 3) provide adequate and stable sources of funds to cover the current and projected 3-5 CHAPTER THREE annual cash needs of the sanitary sewer utility. • The existing customers of the sanitary sewer utility will pay the costs of operating and maintaining the facilities through user rates. In addition, user rates include a portion of the debt service incurred to finance the capital improvements and replacements of the utility facilities. • New customers seeking to connect to the sanitary sewer.system will be required to pay charges for an equitable share of the cost of the system. Revenue from these charges is used to finance part of the Capital Improvement Program. • Customers will be charged for supplemental, special purpose services through separate ancillary charges based .on the cost to provide the service. Ancillary charges increase equitability and increase operating efficiency for services to customers. Revenue from ancillary charges will be used to offset operations and • maintenance costs. • The utility will maintain information systems which provide sufficient financial and statistical information to ensure conformance with rate-setting policies and objectives. • Publicly owned utilities use two widely accepted methods for determining the total revenue requirements of a sanitary sewer utility - the cash basis and the utility basis. The sanitary sewer rates have been developed using the cash basis. • User charges must be sufficient to provide cash for the expenses of operating and maintaining the utility. To ensure the fiscal and physical integrity of the utility, an amount should be set aside each year for capital expenditures from retained earnings. That is, an amount should be set aside to cover some portion of the depreciation of the physical plant. The amount may be transferred from the Sanitary Sewer Fund to the Construction Fund for general purposes or for specific purposes such as to create a reserve for main replacement. • A Working Capital Reserve will be maintained to cover emergencies, bad debts, and fluctuations in cash flow. • The existing customer classes for the utility are single-family, multi-family, commercial, industrial, governmental, and senior citizens. • The inflation rate will be based on information provided by the Finance Department. 3-6 Operational Policies • The large industrial users will be charged for services on the same basis as all other users. • The utility will use generally accepted cost allocation principles for all cost allocation purposes. • The utility's fees and charges should be calculated for the service area as a whole. Rates will be the same regardless of service location (except for the inside City/outside City distinction discussed below). Rates For Outside City (Source: City Policy) • Forcustomers residing outside the City limits, sanitary sewer rates are 1.5 times the residential City rates. LID's/Latecomer's (Source: City Policy, State Law) • Owners of properties that have not been assessed or charged an equitable share of the cost of the sanitary sewer system shall pay, prior to connection to the system, one or more of four charges: latecomer's fees, special assessment charge, utility connection charge, or inspection/approval fees. METRO Charges (Source: City Policy) • Charges and fees levied by the Municipality of Metropolitan Seattle (METRO) shall be passed on to customers. 3. FACILITY POLICIES This section details the planning criteria to be used to establish an optimum behavior level and a standard of quality for the sanitary sewer system. Design Criteria (Source: City Policy) • All sanitary sewer facilities shall be designed to meet the minimum requirements and standards set forth in the "Criteria For Sewage Works Design" prepared by the Washington State Department of Ecology and Title 8, Chapter 5 of the City code. • Analysis and design criteria are detailed in Chapter 4 of this plan. 3-7 CHAPTER THREE Maintenance (Source: City Policy) • The City shall maintain the sanitary sewer system in a safe,reliable, and efficient operating condition with repairs and replacements provided on a scheduled basis that acknowledges a functional and economically useful life of the equipment and facilities. • Equipment breakdown repairs should be made even if overtime labor is involved. • Equipment should be replaced before it becomes obsolete. • Worn parts should be repaired, replaced, or rebuilt before they represent a high probability of failure. • Equipment that is out of service should be returned to service as soon as possible. • A preventive maintenance schedule shall be established for all facilities,equipment and processes. • Spare parts shall be stocked for all equipment items whose failure will impact 1) the ability to meet other policy standards, or 2) the inability to continue providing service to customers. • Tools shall be obtained and maintained to repair all items whose failure will impact the ability to meet other policy standards. • Dry, heated shop space shall be available to all maintenance personnel. • All maintenance personnel shall be trained in the procedures and techniques necessary to efficiently perform their job descriptions. • Maintenance shall be performed by the sanitary sewer maintenance staff and supervised by the Field Superintendent. • Written records and reports will be maintained on each facility and item of equipment showing operation and maintenance history. • The City owns and shall maintain side sewer stubs. If a side sewer becomes plugged, the property owner shall first hire an independent plumber to investigate 3-8 Operational Policies the problem. If it is determined that the problem exists within the City-owned section of the side sewer, then the maintenance crews shall promptly respond and correct the problem. • If an existing gravity sanitary sewer must be extended in order to make a side sewer connection, the property owner must extend the gravity sewer along the full extent of the property. • Restaurant and other food processing establishments shall install and maintain grease traps. Vulnerability ( Source: City Policy) • Vulnerability analysis will be performed to determine a reasonable "worst case" failure for each basin. The analysis will consider the failure of the interceptor and trunk sewers, failure of the largest mechanical component, and power failure to a single power grid. Joint Use (Source: City Policy) • All joint use facilities must comply with Renton policy and design standards. • Joint use facilities located within the City will be maintained by the City of Renton. • Joint use facilities will be pursued only in those areas where they would improve reliability or reduce operating costs. 4. ORGANIZATIONAL POLICIES Structure (Source: City Policy) • The Wastewater Utility shall be operated as an enterprise utility (financially self- supporting). • The Wastewater Utility shall consist of two divisions: planning/design and operations/maintenance. • Wastewater Utility management is accomplished by the Public Works Department managers. 3-9 CHAPTER THREE • The Wastewater Utility shall operate only the municipal sanitary sewer system. Stormwater, water, and other utilities are not administered or operated by the Wastewater Utility. • Wastewater Utility customer service is performed by the Public Works Customer Service Division (general) and by the Wastewater Utility staff (technical). Staffing (Source: City Policy, State Requirements) • The utility staff level is established by the City Council based on the utility requirements and financial resources of the City. • Personnel certification will comply with state standards. The Utility Engineer and Maintenance Supervisor shall be certified. • The City will support staff training. Responsibilities (Source: City Policy) • The Wastewater Utility has the responsibility for sanitary sewer system operation. • Planning, design, operations and maintenance, records management, and customer service and construction will be accomplished by the Wastewater Utility. Relationship with other Departments (Source: City Policy) • The Finance Department is responsible for customer billing, payment collection, project cost reporting and fund activity reporting. • The Personnel Department is responsible for employee records, union labor negotiations, and salary schedules. • The Police Department is responsible for enforcing violations of City sanitary sewer ordinances. 3-10 CHAPTER IV LAND USE POLICIES, ADJACENT SYSTEMS & DESIGN CRITERIA CHAPTER IV LAND USE POLICIES, ADJACENT SYSTEMS & DESIGN CRITERIA A. INTRODUCTION This chapter describes the City of Renton's land use policies, the sewer system's connections with adjacent utility systems, and the sewer system's design criteria. It then describes how land use policies and design criteria were used to develop saturation flow rates that were the basis for a hydraulic computer analysis of the existing system. The City of Renton's land use policies and its sewer system are interconnected with adjacent sewer systems in several ways. Existing land use provides the basis for designing properly sized sewerage facilities,including trunks,interceptors, and lift stations. In most cases Renton's sewers are downstream, or at the receiving end of the effluent, from the systems adjacent to the City. Most of the basins served in part by the City are also served in part by other cities or districts. Therefore, proper planning for Renton's sewers requires that theplans of these adjacent agencies be evaluated B. STUDY AREA As described in Chapter 2 the City of Renton serves six drainage basins, which are: 1) May Creek, 2) Lower Cedar River, 3) Lake Washington East, 4) Black River, 5) Lake Washington West, and 6) Duwamish Estuary. Except for Lake Washington East, all of these basins are also served in part by another sewer agency. The extent of these basins is shown on FIGURE 1. May Creek Basin is partially served by King County Water and Sewer District No. 107. Service within the lower Cedar River Basin is also provided by Cedar River Water and Sewer District and Soos Creek Water and Sewer District. In addition to Renton, the City of Tukwila, City of Kent, and. Soos Creek Water and Sewer District also provide service within the Black River Basin. Both Renton and the City of Tukwila provide service within the Duwamish Estuary. Parts of the Lake Washington West Basin are served by Bryn Mawr/Lakeridge Water and Sewer District and Skyway Water and Sewer District. The study area, shown in FIGURE 5, for this Comprehensive Sewer Plan Update was developed using a variety of criteria. Because, many of the adjacent utilities have sanitary sewer facilities that border the Renton city limits, the study area for the most part, corresponds with the current city limits. Deviations from this norm did occur in the following areas: • Since Water District 90 does not currently provide sanitary sewer service within its service area, a considerable amount of annexation pressure exists in this area. Therefore, the study area was extended into the service area of Water District 90 out to the East Maplewood subbasin limits. 4-1 CHAPTER FOUR • The City of Renton is currently negotiating with Soos Creek Water and Sewer District to revise the service area boundary along their common border. For this reason, the study area included the tentatively agreed upon service area boundary. • Natural boundaries in certain areas make the City of Renton the logical sanitary sewer provider to them. The study area includes the following areas of this kind: • The area lying south of May Creek within King County Water District 107. • The area to the east of the Green River within the City of Tukwila. • The area within the southern portion of the Skyway Water and Sewer District and an area within the eastern portion of the Bryn Mawr/Lakeridge Water and Sewer District. C. LAND USE • I. CITY OF RENTON Development in the service area must be in compliance with the City's Comprehensive Land Use Plan and policies, which represent a long-range plan for growth and physical development of the City. The current character of the City reflects the original Comprehensive Land Use Plan which was adopted in 1965 and revised in 1968. Under this plan, industrial and commercial development was directed toward the Central and Green River Valley areas to allow for further expansion of the City's business center. Residential growth under the plan was primarily directed toward the eastern areas such as the Highlands and Talbot Hill areas of the City, since the West Hill was already developed primarily with residences. A summary of the land use that resulted from this plan is presented in FIGURE 6. Review and updating of the Comprehensive Land Use Plan was initiated in 1975 to incorporate changes made in the economic, legislative, and land use philosophy of the City since the adoption of the original plan. To accomplish this updating, the original plan was divided into four planning areas: the Northeast Planning Area, the Southeast Planning Area, the Central Planning Area, and the Green River Valley Planning Area. Existing and proposed land use for each area was examined,revisions were proposed and hearings were held, with final revisions incorporated into the Revised Comprehensive Land Use Plan. Since 1975 all four Planning Areas have been examined, and Land Use Plans have been revised and adopted for each planning area. Since 1989 the City has been in the process of revising and updating the overall Comprehensive Plan, a process that will not be completed in time for inclusion in this document. 4-2 Land Use Policies/Adjacent Systems/Design Criteria Planned land use within the service area is based on the following City policy. Section 3.A of the Comprehensive Land Use Plan recommends maximizing the use of available utility and service resources in existing areas prior to allowing development of outlying areas. This policy section provides the framework for current land use development and is stated in TABLE IV-1. TABLE IV-1: SECTION 3.A OF THE COMPREHENSIVE LAND USE PLAN 3.A. LAND DEVELOPMENT OBJECTIVE: Growth and development should occur in a timely and logical progression of the existing urban area to maximize the use of existing services. POLICIES: 1. To minimize the necessity for redevelopment, premature development should only be allowed where it can be shown to be compatible with future use in the vicinity. 2. Development beyond the urban fringe should only be allowed where it is a consistent extension of urban services. 3. Vacant land surrounded by developed land should be given priority for development. 4. Land where adequate public utilities are available should be given priority for development. 5. A balance of residential, commercial, and industrial areas should be encouraged. 6. The upgrading and/or redevelopment of marginal areas should be encouraged. 7. The City should identify its sphere of influence. 8. Annexations should have logical boundaries. 9. To reduce processing time and effort and provide for efficient use of existing public facilities, large annexations should be encouraged. 10. Annexations that are economically advantageous should be encouraged. 11. Development requirements should be definite and reasonable. 4-3 CHAPTER FOUR The following objectives of the Comprehensive Land Use Plan are based on the policy statements in TABLE IV-1. • To manage growth and physical development in the City and surrounding unincorporated areas. • To encourage growth in existing areas where the patterns of development are already largely set. • To direct expansion of residential, commercial, and industrial developments into areas where land, utilities, access, and community facilities are available with the capacity to accommodate the projected growth. • Allow higher dwelling densities in areas capable of supporting a higher level of • development and lowering densities in areas where facilities are limited. The existing land uses within the City have been classified into a variety of categories for the purposes of planning and mapping.

The original City was settled in the broad floodplain at the confluence of the Cedar and Black Rivers along the shore of Lake Washington. This area continues to be the heart of Renton; its industrial uses, the airport along Lake Washington and the Central Business District at the foot of Renton Hills are interspersed with older, single-family housing and small apartment complexes. Residential areas were the hills and plateaus surrounding the core area originally developed in the county and annexed to the City. Single-family residential neighborhoods are concentrated in the Highlands, Kennydale Hill, West Hill, Earlington Hill, Talbot Hill, and the ridges along Maple Valley. Along the edges of the single-family neighborhoods and the transportation corridors are concentrations of multi-family housing. Significant concentrations exist along NE 4th Street, NE • Sunset Boulevard, SW Sunset Boulevard, and Benson Road So. In addition to the central business district, commercial areas are concentrated along the major arterials and freeway exchanges, including Rainier Avenue, Grady Way, Sunset Highway, Bronson Avenue, NE 4th Street, the NE 44th Street exit, and SW 43rd Street. The Green River Valley was annexed to Renton in the late 1950s with the intention of developing a second industrial base. This area, which was originally the northern end of a long farming belt along'the Green River, now includes a few residual houses and a significant concentration of manufacturing, warehousing, and office park development. A hub of commercial services is located in the southeast corner of the City limits. Valley Medical Center dominates the land uses along the southern portion of Talbot Hill. Surrounding the hospital is a concentration of support facilities, including medical and dental offices and laboratories. Parks in the Renton area tend to be located along river channels and lake shores. Many parks are located along the Cedar River, including: Liberty Park, Maplewood Golf Course, Cedar River Park, Jones Park, and the Cedar River Trail. Gene Coulon Memorial Beach Park and Kennydale Beach Park are situated directly on the shore of Lake Washington. The City is currently bounded in the south and west by Kent and Tukwila, and to the north by Lake Washington. Future land use is primarily a function of the location of existing vacant land within the City and the rezoning of existing designations. The zoning designations for the vacant land within the City are listed in TABLE IV-4. 4-7 CHAPTER FOUR 2. UNINCORPORATED KING COUNTY Land use within the unincorporated portions of the study area is controlled by the 1985 King County Comprehensive Plan. All of the study area in unincorporated King County is designated "urban." Urban areas are those areas where most new housing and jobs will be located and where most public spending for facilities, services, and open space is normally focused. Comprehensive Plan Policies R-201 and R-202 establish a goal of achieving an average density of seven to eight dwelling units per acre within the urban area. Such an overall density goal cannot be achieved without providing sanitary sewer service to residential development. King County is divided into smaller planning areas called Community Planning Areas. Two community plans, Newcastle and Soos Creek, cover most of the unincorporated areas within the study area of this Plan. The Soos Creek.Community Plan was adopted in November 1979 and is currently in the process of being updated. According to County staff, it is expected that a revised Soos Creek Community Plan will be forwarded to the King County Council for review and adoption in 1991. The Newcastle Community Plan was adopted in 1983. The update process for the Newcastle Community Plan has not been scheduled. 3. SPHERE OF INFLUENCE The City, of Renton has entered into an interlocal agreement with the Cities of Bellevue and Issaquah to establish sphere of influence lines. This agreement was signed by the three jurisdictions in 1979. The sphere of influence agreement places responsibility for long-range planning with the City of Renton within its sphere of influence 4. ADJACENT UTILITY SYSTEMS/JOINT USE AND SERVICE AGREEMENTS The City has entered into several joint use and service agreements with neighboring districts and private customers when it has been economically beneficial. A list and a summary of these joint use and service agreements is presented below. The full text for each of these agreements is presented in Appendix B. • The Tiffany Park Interceptor Joint Use A greement with the Soos Creek Water and Sewer District. • Apollo School Lift Station Service Agreement with King County Water District 90. • Earlington Elementary School Service Agreement. • King County Water District No. 107 Utility Franchise Agreement. • King County Water District No. 107 Joint Use Agreement. • King County Sewer and Drainage District No. 4 Agreement. • City of Kent Agreement. • Cascade Sewer District Service Boundary Agreement. • • Bellevue/Issaquah/Renton Sphere of Influence Agreement 4-8 Land Use PolicieslAdjacent Systems/Design Criteria The City is surrounded by eight adjoining utility entities, seven of which provide sanitary sewer services. These eight utility entities are shown on FIGURE 7. It is evident that some sewer franchise boundaries overlap with the City limits. These areas are also shown in FIGURE 7. The study area for the City's Comprehensive Sewer Plan is shown on FIGURE 5. It includes parts of drainage basins within adjoining utility entities. Areas which may be considered for service boundary adjustments are also shown in FIGURE 5. a. KING COUNTY WATER DISTRICT NO. 107 King County Water District No. 107 provides sewer service in part of the May Creek Basin. The District adopted a Comprehensive Sewer Plan in 1988. Its plan for serving May Creek Basin includes diverting approximately 1,000 acres from the May Creek Basin to the Coal Creek Basin on an interim basis. This plan is based upon two assumptions: first, that it would be too difficult and expensive to construct a May Valley Interceptor at this time, and second, that the City of Renton's service in the southern part of the Basin is adequately provided by the Honey Creek Interceptor. In order to accomplish this diversion, the District is proposing to construct three lift stations and to complete a Coal Creek Interceptor Improvement Project. The sewer franchise boundary for King County Water District No. 107 is shown on FIGURE 7. Two small service area overlaps occur because the City annexed part of the District, but the District has not yet redrawn its boundaries. The District and the City have entered into joint use agreements in the past in order to provide for the construction of sanitary sewer facilities. Joint use agreements will continue to be needed as the May Creek Basin develops. The existing service area gap which is located south of May Creek and east of Honey Creek may best be served by the City. This service area gap is shown on FIGURE 5. b. KING COUNTY WATER DISTRICT NO. 90 King County Water District No. 90 does not currently provide sanitary sewer service. However, the District does have a sewer franchise boundary which is shown on FIGURE 7. The District had a Comprehensive Sewer Plan prepared in 1970, but has not proceeded with the formation of a sewer district due to opposition from the community. Since the District is reluctant to provide sewer service within its franchise boundaries, the City is experiencing annexation pressures from property owners adjacent to the City limits. These annexation requests are for the purpose of obtaining sewer service. For this reason and due to natural drainage patterns, the study area shown on FIGURE 5 4-9 CHAPTER FOUR extends outside the current City limits. c. CEDAR RIVER WATER AND SEWER DISTRICT Cedar River Water and Sewer District provides service to parts of the Lower Cedar River Basin. However, only a small fraction of the wastewater from Cedar River Water and Sewer District ultimately flows through the City of Renton's system by flowing through the Soos Creek Water and Sewer District. The majority of sewage from Cedar River Water and Sewer District flows directly into METRO's Cedar River Interceptor located along the Maple Valley Highway. The District's last Comprehensive Sewer Plan was adopted in 1983. According to the District's engineer, a revised Sewer Plan for Cedar River Water and Sewer District is expected in 1991. The sewer franchise boundary for Cedar River Water and Sewer District is shown on FIGURE 7. A service area overlap occurs as a result of the City's recent annexation of the park area located east of the Maplewood Golf Course. Currently, no sewage facilities are required; the City will provide these services. The Wasmeta Park area is a service area gap between the City and the District. Currently no sanitary sewer facilities exist within this area. If sewer service is needed or required, the City should provide it because it is on the north side of the Cedar River, and the remaining service area of the Cedar River Water and Sewer District is on the south side. d. SOOS CREEK WATER AND SEWER DISTRICT Soos Creek Water and Sewer District adopted a Comprehensive Plan in 1987. The plan acknowledges several service area overlaps with the City of Renton. The District also proposes providing sewer service within portions of the Black River Basin within the City of Renton. Renton has an agreement with Soos Creek Water and Sewer District for joint use of a sewer interceptor in the Tiffany Park Subbasin. The Springbrook Interceptor, owned by the Soos Creek Water and Sewer District located on So. 192nd Street, could provide service to the southernmost portions of the City of Renton. Soos Creek Water and Sewer District currently has a sewer line in 96th Avenue So. north of So. 192nd Street within the City limits. Its 1987 Comprehensive Plan shows the District providing service on both the east and west sides of 96th Avenue So. within the Renton city limits. The sewer franchise boundary for Soos Creek Water and Sewer District is shown on FIGURE 7. Several service area overlaps occur because the City and the District are currently negotiating revisions to the service area boundaries between them. These 4-10 Land Use PolicieslAdjacent Systems/Design Criteria proposed revisions are shown on FIGURE 5. This agreement proposes that the City serve some areas outside the City limits, and that the District serve some areas inside the City limits. e. CITY OF KENT SW 43rd Street is the principal dividing line between the cities of Renton and Kent. Renton has an agreement with Kent to serve a small area south of SW 43rd Street east of 72nd Avenue So. and west of the Puget Sound Electric Railway right-of-way. The City of Kent Comprehensive Sewer Plan was adopted in 1980. The Renton and Kent City limits adjoin each other as shown on FIGURE 7, and there are no service area overlaps or gaps between the two entities, except for that one small area. f. CITY OF TUKWILA A portion of the City of Tukwila east of the Burlington Northern Railroad and south of Longacres is served by the City of Renton. Tukwila also discharges from a lift station into the METRO Sewer System within the City of Renton along SW 10th Street. Tukwila prepared a Comprehensive Sewer Plan in 1984. This Plan shows the extension of sanitary sewer.service by the City of Tukwila into the City of Renton in the vicinity of Longview Avenue So. and SW 33rd, ultimately connecting into the existing Renton system along the railroad right-of-way. The 1984 Tukwila Plan also shows relocating two sewer mains north of I-405 in the vicinity of 72nd Avenue So. and SW 10th Street within the City of Renton in order to eliminate a pump station within the City of Tukwila. The Renton and Tukwila City limits adjoin each other as shown on FIGURE 7. However, a natural service area boundary between the two entities is the Green River, which might be considered for a service area adjustment as shown on FIGURE 5. g. . SKYWAY WATER AND SEWER DISTRICT A copy of the 1984 Comprehensive Sewer Plan for Skyway Water and Sewer District was obtained from the District's engineer. The Plan appears to be a compilation of previous plans that were done for King County and the predecessor to Skyway Water and Sewer District. It appears, however, that no facilities within the Skyway service area directly discharge to, or would affect, facilities within the Renton sewer system. The Skyway Water and Sewer District does not have a sewer franchise boundary according to records provided by King County. However, the franchise boundary may still be under the former King County Sewer and Drainage District No. 4. The service area from the District's Comprehensive Sewer Plan is shown on FIGURE 7. Approximately 60 percent of the District is served with sanitary sewer facilities. A large 4-11 CHAPTER FOUR area within the District, as well as in the service area gap to the south of the District, could be served by gravity to the Renton sanitary sewer system. This area is shown on FIGURE 5. h. BRYN MAWR-LAKERIDGE WATER AND SEWER DISTRICT According to maps provided by the District, Bryn Mawr-Lakeridge Water and Sewer District serves. a small area of Renton along Rainier Avenue near So. 117th Place. Sewage from Bryn Mawr/Lakeridge discharges into the METRO System within the City of Renton at the north end of the Renton Airport. The sewer franchise boundary for Bryn Mawr-Lakeridge Water and Sewer District is shown on FIGURE 7. The eastern part of the District could be served by gravity to the Renton system. This area is shown on FIGURE 5. However, unless this area is annexed • to the City, there is no advantage to this service area transfer. D. ANALYSIS AND DESIGN CRITERIA This section presents the design criteria for sanitary sewage collection system analysis and design. Analysis is necessary to determine the adequacy of the existing system and to identify needs for future facilities. The analysis and design criteria are based on "Criteria For Sewerage Works Design" prepared by the Washington State Department of Ecology, the Municipality of Metropolitan of Seattle (METRO), the City of Renton Standards, actual water usage records, and other accepted engineering criteria and standards for sanitary sewer design and construction. 1. WASTEWATER FLOW RATES - DEFINITION Wastewater in the service area is generated by the population and by non-residential users within it. The Renton Comprehensive Land Use Plan identifies eleven, separate land use categories. For sanitary sewer planning purposes, these eleven categories were used to determine wastewater flow rates for the hydraulic computer model. The eleven land use categories are listed in TABLE IV-3. Eleven saturation land use populations were determined by calculating the areas of each designated land use category. This was accomplished by assigning land use designations to all parcels within a land use boundary on a computer base map that was used for producing the figures for this plan. Saturation was defined as the point at which development is complete within a land use designation. 4-12 Land Use Policies/Adjacent Systems/Design Criteria 2. WASTEWATER FLOW CRITERIA Wastewater flows can be divided into four major components, which are 1) domestic wastes, 2) industrial wastewater, 3) infiltration, and 4) inflow. The wastewater flow criteria used for each or these four components is presented in TABLE IV-5. a. DOMESTIC WASTEWATER Domestic wastewater flows are essentially equal to winter-time water consumption and are are typically established on a per capita basis. The average domestic wastewater flow used for analysis and design of the sanitary sewer system is 80 gallons per day per person. b. COMMERCIAL/INDUSTRIAL WASTEWATER Commercial and industrial wastewater is defined as the wastewater generated from a specific commercial or industrial operation. Commercial and industrial wastewater does not include waste generated by employees of the industry, which is considered domestic waste and excluded from this category. c. INFILTRATION Infiltration is the entrance of groundwater into the sanitary sewer system through cracks, pores, breaks, and defective joints in the sewer piping network. Additional infiltration also results from the_entrance of storm- water through manhole covers. The quantity of water that may infiltrate into a sanitary sewer system depends upon many variables, such as the age of the system, materials used in construction, and the service area's hydrology, soils and groundwater level. However, the design of the sewer system, including mains, laterals, and individual connections, along with inspection during construction, will have substantial impact on the quantity of infiltration. Due to improvements in construction materials and practices, systems installed after 1960 generally show a decrease in the quantity of groundwater infiltration. The use of non- porous piping materials and rubber-gasketed type joints will help reduce infiltration and will improve the condition and life of the sanitary sewer system. The design allowance for infiltration is shown in TABLE IV-5. 4-13 CHAPTER FOUR , TABLE IV-5: WASTEWATER FLOW CRITERIA Average Domestic Sewage Flow: 80 gals/day/person Average Population Density 2.40 person/dwelling unit single-family (U.S Census Bureau, 1980): 2.20 person/dwelling unit multi-family Residential Density: Single-Family Residential 6 dwelling units/acre Low-Density, Multi-Family Residential 12 dwelling units/acre Medium-Density, Multi- Family Residential 18 dwelling units/acre High-Density, Multi- Family Residential 24 dwelling units/acre Commercial and Industrial Sewage Flows': Light Industrial 2800 gals/acre/day (gpad) Heavy Industrial site specific I ' Commercial 2800 gpad Office 2800 gpad Recreation 300 gpad Green Belt 0 gpad Public 600 gpad Manufacturing Park 2800 gpad Infiltration and Inflow (METRO): Peak Infiltration 700 gpad Peak Inflow 600 gpad Peaking Factors System Average 2.0 x Depth/diameter ratio 0.70 * Design flow criteria vary considerably,depending upon land use 4-14 Land Use Policies/Adjacent Systems/Design Criteria d. INFLOW Inflow refers to direct flows of stormwater into sanitary sewer systems through hookups from stormwater collection facilities and illegal connections. Stormwater inflow is due mainly to unauthorized connections to the sanitary sewer system. The enforcement of regulations banning the illegal connections to the sanitary sewer system along with continued efforts to identify and correct previously unauthorized connections minimize stormwater inflow. The design allowance for stormwater inflow is shown in TABLE IV- 5. 3. SANITARY SEWER DESIGN CRITERIA All sewer lines within the City of Renton shall be designed in accordance with good engineering practice by a professional engineer with minimum design criteria presented in Chapter 2 of the "Criteria for Sewerage Works Design," prepared by the State of Washington Department of Ecology, October 1985,or as superseded by subsequent updates. This chapter includes standards and guidelines for design considerations (minimum pipe sizes, pipe slopes and wastewater velocities),maintenance considerations,estimating wastewater flow rates,manhole locations,leak testing and separation from water pipelines. These criteria have been established to ensure that the sanitary sewers convey the sewage and protect the public health and the environment. The sewer lines shall also conform to the latest City of Renton Standards and Specifications. Detailed standards are included in Title 8, Chapter 5 of the City Code which is presented in Appendix D. Requirements relating to design are listed below. a. DESIGN LOADING FOR SANITARY SEWER FACILITIES Sanitary sewer system flows are composed of residential, institutional, commercial, and industrial sewage, along with infiltration and stormwater inflow. Sanitary sewer systems must be capable of conveying the ultimate peak flows of these wastewater sources. No overflows shall be permitted. b. DESIGN PERIOD The design period is the length of time that a given facility will provide safe, adequate and reliable service. The period selected for a given facility is based on its economic life, which is determined by the following factors: the structural integrity of the facility, rate of degradation, cost of replacing the facility,cost of increasing the capacity of the facility, and theprojected population growth rate serviced by the facility. Collection and interceptor sewers are designed for the ultimate development of the contributing area. The life expectancy for new sanitary sewers, using current design practices, is in excess of fifty years. 4-15 CHAPTER FOUR c. DESIGN OF SANITARY SEWER FACILITIES Allowable sewer pipe shall be ductile iron, cast iron, PVC, or concrete. For normal depth, PVC is generally preferable, because it has longer laying lengths, which results in fewer joints, reducing the potential for infiltration. Gravity sewers are sized to provide capacity for peak, wet-weather flows. The smallest diameter sewer allowed is 8-inches. All sewers will be laid on a grade to produce a mean velocity when flowing half-full of at least 2 feet per second. Manholes will be at least 48-inches in diameter and will be spaced at intervals not to exceed 400 feet on sewer lines 15-inches in diameter or less, and 500 feet on sewer lines 18-inches in diameter or larger. The design parameters are summarized in TABLE IV-6. d. ROUGHNESS COEFFICIENT The Manning equation shall be used to design and analyze wastewater flow characteristics of the sanitary sewers. The Manning roughness constant [n] shall vary depending on the pipe material. Typical values are summarized in TABLE IV-6. e. REFERENCE DATUM The King County Aerial Survey (K.C.A.S.) is the common datum used within the City of Renton for design and construction of sanitary sewer facilities. f. SEPARATION BETWEEN SANITARY AND OTHER FACILITIES The Department of Ecology requires separation of water and sewer facilities for health reasons. Sanitary and storm sewer facilities shall have basic separation requirements for construction purposes. A minimum horizontal separation of five (5) feet between sanitary and other facilities shall be maintained. Wherever possible, a horizontal separation of seven (7) feet is desirable. These distances are measured edge to edge. g. HYDRAULIC ANALYSIS The sanitary sewer system hydraulic analyses will be performed using the City's hydraulic computer model. All new developments, with the exception of developments involving less than five single-family residences, will require an analysis. The developer shall be responsible for paying the cost of the analysis of the sanitary sewer system. If the analysis concludes improvements need to be made, the developer and the City may need to negotiate about who will pay the costs. 4-16 Land Use Policies/Adjacent Systems/Design Criteria TABLE IV-6: SANITARY SEWER DESIGN CRITERIA Sanitary Sewer Sizing Peak Wet-Weather Flow Minimum Sewer Size 8 inches in Diameter Pipe Materials PVC Reinforced Concrete Pipe Cement Lined Ductile Iron Cement Lined Cast Iron Manholes Maximum Spacing 400 feet Minimum Manhole Size 48 inches in diameter • Minimum Clear Opening 23 inches in diameter Maximum Depth 20 feet (where possible) Separation From Water Mains Horizontal Separation (Parallel) 10 feet Vertical Separation (Perpendicular) 18 inches Hydraulic Criteria Depth to Diameter Ratio 0.70 Minimum Scouring Velocity 2 Feet Per Second Manning Roughness Coefficient PVC 0.011 Concrete 0.012 Lined DI/CI 0.012 Vitrified Clay 0.013 4. LIFT STATION DESIGN CRITERIA Sewage lift stations within the City of Renton shall be designed in accordance with good engineering practice by a professional engineer using the minimum design criteria presented in Chapter 3 of the "Criteria For Sewerage Works Design," prepared by the Washington State Department of Ecology,October 1985, or any subsequent updates, and shall conform to the latest 4-17 CHAPTER FOUR City of Renton standards and specifications. Detailed standards are included in Title 8, Chapter 5 of the City Code, which are presented in Appendix D. Requirements relating to the design are listed below. a. DESIGN LOADING FOR LIFT STATIONS Lift stations shall be designed to handle the peak, wet-weather flow from the contributing area. All lift stations shall have a minimum of two pump units, each with the capacity to handle the expected maximum flow. b. DESIGN PERIOD The design period for lift stations shall take into consideration long-term needs, replacement or expansion difficulties, service area growth rate and useful life. A lift station should have a minimum design period of twenty years for the facility and ten years for mechanical and electrical equipment. Consideration should be given to longer design periods for lift stations that are expected to serve an indefinite life. Consideration must also be given to the ability of the consumers to pay for the facilities. c. DESIGN OF LIFT STATION FACILITIES Lift stations shall be designed with a minimum of two pumps, both of which have the capacity to convey peak, wastewater flow rates. If wide variations in wastewater flow rates are expected into the lift station, then consideration should be given to the use of three or more pumping units. If three pumps are used, two of them must have the capacity to convey peak, wastewater flow rates. Each pump shall be capable of passing spheres of at least 3-inches in diameter. Each lift station will be provided with either an on-site or portable power backup. A lift station designed for portable power backup will be provided with sufficient wet-well storage to allow adequate time for City maintenance personnel to transport, setup, and provide the necessary backup, during a power outage. Wet-well storage will be designed on the basis of the peak, wet-weather flow. Force mains shall be sized to maintain a minimum velocity of 2 feet per second. The force main shall have a maximum velocity of 10 feet per second when all pumps are operating together. Regardless of these velocity criteria, minimum size shall be 4-inches in diameter. 4-18 Land Use Policies/Adjacent Systems/Design Criteria 5. ELIMINATION OF LIFT STATION FACILITIES Lift station facilities are typically eliminated through the development of the gravity sewer system. Highest priority should be given to elimination of lift station facilities because of their high degree of vulnerability and high operation and maintenance costs. These considerations include environmental risks, life-cycle costs, lift station impacts on downstream sanitary sewer facilities, vulnerability to vandalism, and lift station accessibility. 4-19 aY OF,: s A .

CHAPTER V SYSTEM ANALYSIS CHAPTER V SYSTEM ANALYSIS & RESULTS A. INTRODUCTION This chapter presents a detailed analysis of all aspects of the existing system and their recommended improvements. Three system components--the wastewater collection system, lift stations and the telemetry and control system--are identified and described and then the results of either their hydraulic or structural analysis are presented. Other deficiencies that do not apply to one system component are presented at the end of this chapter. Many sections of the existing sanitary sewer system have problems which fall into four categories: deficient capacity, aging pipes, infiltration and inflow, and combined sewers. Capacity problems in the existing sanitary sewer system have been identified using a hydraulic computer model. The hydraulic analysis was conducted by entering saturation wastewater flow rates in a computer model of the existing system to determine if it could adequately convey them. Capacity problems do occur throughout the system in various degrees and are a result of inadequate pipe sizes or slopes. Much of the existing sanitary sewer system was installed during the 1940s and 1950s as a federal program to provide housing for workers at the Renton Boeing Plant. Many of these sewers have reached the end of their useful economic life and require replacement. Many of them are in the North Highlands and South Highlands Subbasins. The City of Renton is currently in the process of replacing these aging sanitary sewers. Infiltration and inflow occur in all sanitary sewer systems. Infiltration is defined as water entering the sanitary sewer system through pipes, joint connections, manhole covers and walls. Inflow is defined as water discharged to the sanitary sewer system through connections to roof drains, yard drains, foundation drains, and cross connections with storm sewers and combined sewers. The combination of both infiltration and inflow can be a major portion of the total wastewater flow which must be carried by the sanitary sewer system. Infiltration and inflow problems in an existing sanitary sewer system can be studied to determine their effect Many infiltration and inflow problems can be corrected through grouting of existing pipes and manholes, replacing damaged pipes, and eliminating illegal connections to the sanitary sewer system. Combined sewers are designed to carry both stormwater and wastewater within a single system, which current design practices in the City of Renton do not allow because it causes stormwater, which is relatively clean, to be treated along with wastewater. Combined sewersystems within the City have been replaced with separate sanitary and storm sewer systems, except for one along the lakefront in the Kennydale area. 5-1 CHAPTER FIVE 1. HYDRAULIC ANALYSIS A hydraulic computer model of the City's sewer system was developed as a part of this plan update. The purpose of this model was 1) to evaluate the existing sanitary sewer system and determine areas of capacity constraint,land 2)to provide a tool for planning future improvements. The hydraulic computer model was created using a software package designed by Specialized Software Products, Inc., of Tukwila, Washington. Two basic kinds of data were needed for the computer model:physical data and wastewater flow data. The physical data of the sanitary sewer system was taken from as-built drawings and other records provided by the City. Physical data was only available for 60 to 70 percent of the sanitary sewer system. As a result the unmodelled portion of the sanitary sewer system cannot be evaluated using this computer model. The physical data entered into the computer model included manhole numbers, pipe invert elevations at each manhole, and pipe length, diameter, and material type. Physical data not entered was the age or date of construction of the various system components. The wastewater flow rates entered into the computer were based on estimated saturation conditions because those are the basic criteria around which sanitary sewer facilities are designed. Domestic wastewater flow rates were determined by land use designations for the entire City. The wastewater flow rate criteria set for each land use designation is summarized in TABLE IV- 3. The entire sanitary sewer system was first divided into sections and those sections divided into their land use designations. The total area of each land use designation within each section was calculated and then used to determine the domestic wastewater flow rate and infiltration and inflow data. The resulting flow rates and data were then divided equally amongst the sanitary sewer manholes within that land use designation. Pump flow rates from each of the lift stations were determined through review of the operations and maintenance manuals, and this flow data was distributed to the appropriate manholes. The hydraulic computer model output was developed through a mathematical synthesis of the physical data and wastewater flow rate information which was entered into the model's data base for each pipe section. The maximum capacity of each pipe section was determined using the Manning's equation. A depth to diameter ratio of 0.70 was used to describe the maximum, desired hydraulic condition within a pipe section. The Manning's co-efficient for the various , pipe materials is listed in TABLE IV-3. The slope used in the Manning's equation was calculated by the computer model using the invert elevation of the upstream and downstream manholes. The expected peak, wet-weather flow rate at saturation was calculated using the various flow rates entered onto the model data base. A peaking factor of 2.0 was applied to the domestic flow 5-2 System Analysis and Results rate entered into each manhole. The peak, domestic flow rates, infiltration and inflow, and lift station flow rates were then summed downstream through the entire basin. The model output includes the peak, wet-weather flow rate and maximum velocity for saturation conditions. The hydraulic analysis of the existing sanitary sewer system involved several steps. First, a comparison between the peak, wet-weather flow rates and the maximum capacity of each pipe section was made. A pipe section was determined to be over capacity if the ratio of the peak, wet-weather flow rate to the maximum flow rate was over 70 percent. This provided a safety factor which would help account for variations in the Manning's co-efficient and missing data not entered into the computer data base. The second step identified the pipe sections with adverse pipe slopes (those pipe sections where the upstream manhole is lower than the downstream manhole), and the third step identified pipe sections which were constructed within inadequate slopes to achieve carrying velocity. This model will be used by the City in the future to evaluate changes to the existing system or additions to the system during the design phase of each sewer project. However, to increase the reliability of the model output, it is necessary that the City generate the physical data for the remaining sewer system that is not currently modeled. In addition, the existing physical data and wastewater flow data entered in the current model should be checked and verified. Finally, a model report should be prepared in order to document the information used in developing the model and to generate a complete print out of both the input data and the output results. 2. STRUCTURAL ANALYSIS A structural analysis is a visual inspection of the existing system either by a video camera or actual inspection during normal operations and maintenance. The Sanitary Sewer Maintenance Division owns and operates its own sewer video inspection equipment. At this time, the video equipment is used approximately one day per week. Video inspections have been organized and documented since 1988. The video inspection averages approximately 1500 feet per day. The inspection process requires hydraulic jet cleaning of the sanitary sewer section prior to the video inspection. After completion of the video inspection, roots are cut and cracks are sealed, if necessary, before proceeding to the next section. The video inspection equipment requires three people to operate. If traffic control is necessary, two additional people are required. At the current rate, it will take twelve years to video inspect all existing sanitary sewers. It is recommended that sewers near the end of their useful life be video inspected every five years. All other sewers should be inspected every ten years. 5-3 CHAPTER FIVE Currently, the video tapes taken by the maintenance crews are stored and cataloged at the City Shops. However, sanitary sewer video tapes of new additions are stored in uncataloged boxes which are then placed in the City's archives. The City should catalog all sanitary sewer video tapes using a computerized data base and store them in a single location for easy retrieval. B. SYSTEM-WIDE CONCERNS 1. METRO -INTERCEPTOR SURCHARGE During peak flows, METRO will use its interceptors for storage of wastewater and for controlling flows in the Renton Treatment Plant. This results in surcharging of the METRO interceptors. METRO reserves the right to surcharge its interceptors to an elevation of 22 feet. METRO has never reached this extreme; however, the City has experienced a sewer surcharge problem in the low lying areas. The surcharge elevation of 22 feet is shown on the Sanitary Sewer Hydraulic Profile (FIGURE 2). This hydraulic profile illustrates that the City's sanitary sewers would be affected by METRO's surcharging, because their inverts are below the 22-foot elevation. As a result of METRO's surcharging, it is possible that additional wastewater could overflow in low lying areas through manhole covers and side sewer connections. The City has not designed facilities to accommodate a sewer surcharge to an elevation of 22 feet. the City's current position is that METRO is responsible for providing adequate capacity within its interceptors and wastewater treatment facilities. In addition, the City considers METRO to be responsible for proper effluent disposal. During the preparation of the Comprehensive Sewer Plan, no analysis was made of the effect of METRO's surcharging on the City's sewer system. METRO should conduct such a study to identify areas of potential risk and alternatives to mitigate this problem. 2. ADJACENT UTILITY SYSTEMS For purposes of this plan, all of the comprehensive plans for the adjacent utility systems described in Chapter 4 were examined. This plan's analysis used their predictions for the future capacity they will need when they convey wastewater through Renton. However, adjustments to the City's interceptors may need to be made as these systems further clarify their needs. The City of Renton has several agreements with adjacent utilities that allow joint use of facilities within the City. It is important that these adjacent utilities are restricted to the volume of wastewater discharged to the joint use facilities. If capacity problems become evident, through visual inspection or flow measurements, then the City and the adjacent utility should work together to investigate the potential sources, both inside the City and within the adjacent utility to correct the problem. 5-4 System Analysis and Results 3. STRUCTURAL PROBLEMS The following is a discussion of specific problems that are associated with the gravity sanitary sewer system in the City of Renton. AGING SEWERS Many of the gravity sewers within the central business district and the Highlands were constructed in the 1940s as a result of housing construction during the war for the Boeing plant in Renton. Many of these sewers have reached their design life. expectancy (approximately 50 years); as these sewers approach the end of their useful life, increased maintenance and structural inspections should occur to locate and prevent pipe failures. This comprehensive plan identified some of the older sewers and has established a capital improvement program to replace and upgrade them. The City should continue this process. REVERSE SLOPES AND PIPE SAGS A major maintenance problem,associated with sanitary sewers that are laid with a reverse slope, or have a sag due to improper construction or differential settlement, is that they require periodic cleaning to remove debris. There are approximately 90 such sewer sections within the City. ROOT PROBLEMS Tree roots cause problems in sanitary sewers by penetrating and cracking sanitary sewer pipe joints to feed on the wastewater. Tree roots can also create blockages, resulting in backed-up sewers. The City has approximately 30 sections of pipe which require routine, root cutting maintenance to prevent wastewater backups and reduce pipe damage. GREASE PROBLEMS Grease problems are typically associated with major food processing operations, the majority of which involve restaurants where grease is a component of the wastewater. Many of the older restaurants within the City do not have grease traps. Newer restaurants have been and will continue to require the installation of grease. traps; however, many of these grease traps are not properly maintained because of a lack of proper monitoring. Grease buildup problems occur most often in the side sewers. However, some grease buildup problems also occur in the sanitary sewer collection system. When problems do occur, the City maintenance crews are usually called out to investigate. The City will need to allocate additional maintenance hours for monitoring 5-5 CHAPTER FIVE this problem. Ultimately, a proper monitoring program should reduce maintenance time involved in removing grease buildup. Preventive maintenance should involve the installation of grease traps in all restaurant and food processing type facilities and proper maintenance of those grease traps. An ordinance shouldbe prepared requiring owners of grease traps to write a letter, on an annual basis, certifying that proper inspection and maintenance have been performed. Certification should require a small fee to cover administrative costs. Fines should be imposed for certification fraud of improper inspection and maintenance practices. In addition, cost of cleanup due to problems associated with improperly maintained grease traps should be assessed to property owners. 4. EARTHQUAKE PREPAREDNESS The Seismotectonic Map of the Puget Sound Region (Gower and others, 1985) shows two significant faults and three small faults less than 10 miles from Renton City Hall. These faults are zones of weakness in the bedrock that could possibly be the sites of future earthquakes. The largest fault lies north of Renton; it is inferred on the basis of an abrupt change in relief (an escarpment) in the bedrock topography of the Puget Lowland. Many small earthquakes (<3.5 on the Richter Scale) have been detected along this escarpment, especially beneath Seattle and Mercer Island where the depth to bedrock is deepest. The escarpment has an east-west trend which is perpendicular to the regional,north-south structural trend of the Puget-Willamette trough and the Cascade range. Because the basin in the bedrock north of this escarpment is filled with sediments, it is not expressed at the surface from Winslow to Mercer Island. However, east of Mercer Island, where it closely parallels I-90, it is marked by the high relief of the Newcastle Hills, Squak Mountain and Tiger Mountain. The middle to lower Tertiary rocks comprising those hills, and possibly upper Tertiary sediments (Walsh,personal communication, 1990) are strongly folded. Despite the seismic record of numerous earthquakes along the escarpment, no rupture or deformation of the ground surface appears to have occurred during the last 15,000 years. Another major fault that passes through Renton may begin in Bremerton and extend to Issaquah or connect with the well defined Hobart fault east-south-east of Renton. This fault is locally well expressed in lower to middle Tertiary rocks, but it does not deform Vashon glaciation and younger sediments (<15,000 year old). Furthermore, because historical earthquakes are not -- concentrated along its trend, this zone of weakness in the bedrock does not appear to be a hazard. Similarly, smaller faults west of Renton in Tukwila and through the South Center area, cut only the bedrock and do not appear to have been active for at least 15,000 years. Although direct rupture of the ground surface due to a major earthquake originating in the Renton area is unlikely, ground shaking and failure resulting from a regional magnitude 6.5 to magnitude 5-6 System Analysis and Results 7.5 earthquake is likely during this decade. The recurrence interval for deep earth quakes (>40 km deep) of this magnitude is about 25 years in the Puget Lowland. Because so many earthquakes have occurred during the 14,000 years since the glacially sculpted landscape emerged from beneath the melting ice,most features and sediments are adjusted to the ground motion of magnitude 7 or an even larger event. However, steep slopes that have been undercut by rivers, .man or the natural weathering and sapping processes of migrating groundwater, will be susceptible to failure. Particularly likely to fail (liquefy or slump) are areas of recent fill like the Cedar River delta and man-made deposits of insufficiently compacted saturated sandy to silty soils. In, general, structures close to bedrock will be less impacted by ground motion than those on unconsolidated sediments or man-made fill. However, the topography of the bedrock surface beneath Renton will have a major influence on the focusing or attenuation of seismic energy. Areas overlying old valleys or basins in the bedrock, where fill may be hundreds of feet deep, may receive up to ten times the shaking that neighboring bedrock hillsides will experience (Ihen and Hadley, 1986). Thus, facilities designed for the Duwamish valley and Maplewood area will have to meet higher standards of seismic design. Water and sewer systems of the Renton area will very likely experience the significant ground motion associated with about a magnitude 7 earthquake during the 1990s. Because Renton has developed both on bedrock and deep fills of unconsolidated sediments, seismic energy will be locally focused, and very different degrees of ground motion will be experienced by different parts of the system. Lift stations should be located as close to bedrock as possible, and the system should be designed to accommodate significant changes in seismic stress over relatively short distances (tenths of a mile). C. WASTEWATER COLLECTION BASINS The following section of this chapter presents an analysis of wastewater collection basins, which is presented in an order based on the seriousness of each basin's deficiencies. See FIGURE 1 for a location of basins. A brief summary of those deficiencies follows. • The wastewater within the May Creek Basin is currently diverted into the Lake Washington East Basin causing an overload of that system. The construction of the May Valley Interceptor is necessary to correct these problems. • In the Lower Cedar River Basin, a moratorium on development is in place because the sewer pipe lines are currently over capacity. 5-7 CHAPTER FIVE • Lake Washington East Basin currently receives wastewater from the Sunset Lift Station .which significantly contributes to overloading the North Highlands Interceptor. • The Panther Creek subbasin in the Black River Basin is at or near capacity; the Renton Industrial Subbasin is experiencing increasing demands as a result of land use changes. • In the Lake Washington West Basin, the West Renton subbasin has sections of sewer lines that experience some capacity problems. • The Duwamish Estuary Basin is for the most part undeveloped and is not experiencing capacity problems at this time. 1. MAY CREEK BASIN The May Creek Basin is located in the northeast part of the City. Most of this basin is currently unsewered and is located on the periphery of the City's current service boundary. The May Creek Basin is jointly served with King County Water District No. 107. The City serves approximately 910..acres of this basin which consists of primarily single-family and light commercial land uses. The ultimate sewerage of the May Creek Basin will be through the extension and completion of the proposed May Valley Interceptor. At this time, the following three lift stations serve low lying areas along Lake Washington in this basin: Misty Cove, Baxter and Denny's Lift Stations. The City is experiencing development pressure within the May Creek Basin and the Honey Creek Subbasin,which requires immediate attention be given to the sanitary sewer facilities in this area. The primary concern is the Devil's Elbow Lift Station. This lift station was designed and constructed in 1985 to accommodate existing development. In addition, the Devil's Elbow Lift Station has experienced operation problems and the force main is structurally unreliable due to soil movement along NE 27th Street. The City is attempting to accelerate the construction of the May Valley Interceptor with the assistance of King County Water District No. 107. The May Valley Interceptor would eliminate the need for the Devil's Elbow and Sunset lift stations. Elimination of these lift stations would also eliminate many of the capacity problems within the Kennydale and North Renton Subbasins. However, completion of this interceptor, along with Phase IV of the Honey Creek Interceptor, is not expected until 1993 at the earliest. 5-8 System Analysis and Results Interim improvements to the Devil's Elbow Lift Station should be studied. These interim improvements could be completed in 1991 and would increase the reliability and possibly the capacity of the Devil's Elbow facilities. HONEY CREEK SUBBASIN The May Creek Basin includes the Honey Creek Subbasin, which is currently served by the Sunset, Summer Wind and Devil's Elbow Lift Stations. These lift stations currently pump wastewater collected in the Honey Creek Subbasin to the Lake Washington Basin East. They will be removed from service after completion of the May Valley Interceptor and the Honey Creek Interceptor. This is a large subbasin serving approximately 430 acres of the city. The sewage is routed to Sunset Lift Station where it is pumped to the North Highlands Subbasin. A serious capacity problem exists in this subbasin within the interceptor along Sunset Avenue east of Union Avenue. The sanitary sewers within the Honey Creek Subbasin are designed to direct 95 percent of the wastewater toward the Sunset Lift Station. This results in excessive overloading of this lift station. On many occasions the Sunset Lift Station is required to operate both pumps continuously for several days, which is an undesirable operating condition. In addition, wastewater discharged from this lift station adversely impacts gravity sewers in the North Highlands Subbasin. If the sunset lift station cannot pump all of the incoming flow, the wastewater is automatically discharged through an overflow device to the Honey Creek Interceptor and is then pumped to the Kennydale Subbasin through the Devil's Elbow Lift Stations. During peak storm events, wastewater flow rates have been know to exceed the capacity of both the Sunset and Devil's Elbow Lift Stations. This has resulted in raw sewage overflows into Honey Creek. A large potential for development exists within this subbasin, and the correspondingly higher flows will create more extensive capacity constraints in the future. A more detailed description of the capacity problems of the Devil's Elbow Lift Station can be found in the lift station section of this chapter. As reported in the 1983 Comprehensive Sewer Plan, sanitary sewers within the Honey Creek Subbasin exhibit substantial amounts of infiltration and inflow, which results in excessive loading of the Sunset Lift Station and periodic overflows into Honey Creek. In an attempt to reduce the amount of infiltration and inflow within this subbasin,the City contracted with Gelco Grouting Service to examine and correct infiltration and inflow problems within this basin. The work was separated into three phases under project Nos. S-370(1983), S-379(1985), and S-421(1986). In addition, the City also constructed the Honey Creek Interceptor, which is currently designed to receive the wastewater from the Honey Creek Subbasin that cannot be handled by the Sunset Lift Station. 5-9 CHAPTER FIVE 2. LOWER CEDAR RIVER BASIN The Lower Cedar River Basin includes the eastern portion of the City of Renton bordering the Cedar River. The City serves approximately 2610 acres at this basin which consists of primarily single-family and multi-family developments with some commercial and light industrial land uses. This basin includes the Central Renton, South Highlands, Maplewood, Heather Downs, East Maplewood, and Tiffany Park Subbasins. Due to extensive development and annexation pressures within this basin, an engineering investigation of the sanitary sewer system in the South Highlands, Maplewood and Heather Downs Subbasins was performed in the spring of 1989 by RH2 Engineering. The results of this study are present in a report entitled An Engineering Investigation of Sanitary Sewer Facility Improvements for the East Renton, Heather Downs, and South Highlands Areas. These results indicated inadequate sanitary sewer capacity in the South Highlands and Heather Downs Subbasins, and limited available capacity in the Maplewood Subbasin. As a result of this engineering investigation, the City Council passed Resolution No. 2764, which established a moratorium on the connection of new construction to any of the existing sanitary sewers in the South Highlands, and Maplewood or Heather Downs Subbasins. The moratorium will be in effect until January 31, 1992, unless extended by the City Council. The City is currently working the environmental study and predesign alternatives for the proposed East Renton Interceptor which would solve the sanitary sewer capacity problem. CENTRAL RENTON SUBBASIN The Central Renton Subbasin includes the central business district of the City located north of the Cedar River and south of North 3rd Street. Many of the sewers in this subbasin are old and some have experienced structural failure. This area is within Zone 1 of the Aquifer Protection area, and exfiltration from these sewers could contaminate the City's drinking water supply. This area consists primarily of residential and commercial land uses. SOUTH HIGHLANDS SUBBASIN The South Highlands Subbasin is located south of NE 7th Street and north of NE 4th Street in the Highlands area. Land use in this subbasin consists primarily of single-family residential_developments. This is a large subbasin serving approximately 600 acres. It connects into the METRO Interceptor at North 4th Street and Logan Avenue North. Two lift stations pump into this basin: Honeydew and Union 600. As a result of development pressures within this 5-10 System Analysis and Results subbasin, an engineering investigation on the sanitary sewer system was performed in 1990 by RH2 Engineering. The results of this study are presented in a report entitled An Engineering Investigation of Facility Improvements for the South Highlands Sanitary Sewer Basin. The major problem identified for this subbasin is an inadequately sized interceptor, which the report presented options for correcting. The capacity created through the East Renton project will benefit this basin. MAPLEWOOD SUBBASIN The Maplewood Subbasin is located primarily south of NE 4th Street. This area serves a variety of land uses including single-family and multi-family residential as well as some commercial and light industrial land uses. This subbasin receives wastewater pumped from the Union 600 Lift Station. This subbasin connects into the METRO Cedar River Interceptor along the Maple Valley Highway. This subbasin has adequate sewer capacity for existing development. However, future development will require either the construction of additional sewer capacity or the reduction of existing wastewater flows such as the elimination of the Union 600 Lift Station. HEATHER DOWNS SUBBASIN The Heather Downs Subbasin is located along the eastern border of the city limits. This subbasin consists primarily of single-family residential development with some multi- family developments in the northern portion of this subbasin. Several capacity problems currently exist within this subbasin. The City is currently developing solutions through the East Renton Interceptor project which would alleviate the sewer capacity problems. This project is in the predesign and environmental review stage. In addition to the capacity problems in the Heather Downs Subbasin, a section of the Heather Downs Interceptor was constructed on a very steep slope (approximately 65% slope). The sewer section in question is located along a power line easement near the plat of Maplewood. The interceptor was constructed using 10-inch PVC sewer pipe with concrete collars to stabilize the pipe on the steep slope. No indication of potential structural failure exists. However, a study should be conducted to determine the integrity of the sanitary sewer. The City should video inspect this sewer to examine the internal integrity and to locate any pipe or manhole movement. If a problem is found, a geotechnical consultant could examine the steep slope for stability and the potential of soil shifting. This information will help determine the need for construction of an interceptor in a new alignment. 5-11 CHAPTER FIVE EAST MAPLEWOOD SUBBASIN The majority of the East Maplewood Subbasin is located outside the city limits. Currently a majority of this basin is unsewered. The small portion that is sewered is being pumped to the South Highlands Subbasin through the Honeydew Lift Station. With recent development in this area, the City is currently studying the construction of an interceptor in this subbasin to serve areas within the City through the East Renton Interceptor Project. T1rFANY PARK SUBBASIN The Tiffany Park Subbasin is located on the south side of Cedar River. This subbasin includes primarily single-family and multi-family developments. This subbasin includes two lift stations: the Falcon Ridge Lift Station and the Cottonwood Lift Station. In addition, this subbasin receives wastewater from the Soos Creek Water and Sewer District. The Tiffany Park Interceptor is a joint use facility between the City of Renton and the Soos Creek Water and Sewer District (formerly Cascade Sewer District). The gravity interceptor is currently not experiencing capacity problems, but there is evidence that peak,wastewater flows exceed the design capacity of METRO's inverted siphon crossing the Cedar River. METRO is considering replacing the inverted siphon with a new gravity sewer which would be sized to accommodate these peak flows. This new METRO sewer would be located on a bridge over the Cedar River that could be used for a proposed trail. The majority of the wastewater in this interceptor originates in the Soos Creek system, including Soos Creeks Lift Station No. 5. According to the Soos Creek Comprehensive Sewer Plan, Lift Station No. 5 is considered to be a permanent facility which serves a large basin. As development of this basin proceeds, increased pumping from the lift station will aggravate capacity problems in METRO's inverted siphon and increase the potential for wastewater release to the Cedar River. 3. LAKE WASHINGTON EAST BASIN The Lake Washington East Basin is located in the northern part of the City and includes the Kennydale, North Highlands and North Renton areas of the.City. The City serves this entire basin of 2100 acres which consists of a variety of land uses including single-family and multi- family residential , light commercial and heavy industrial activities. This basin is divided into four subbasins which collect wastewater and transport it to METRO's East Side Interceptor. 5-12 System Analysis and Results KENNYDALE LAKEFRONT SUBBASIN The Kennydale Lakefront is the northernmost subbasin in the Lake Washington East Basin. This subbasin serves primarily residential communities and includes the Lake Washington Flush Station and Lake Washington Lift Station No. 2, which serve the residential community adjacent to Lake Washington (Coleman Point). This is a medium size subbasin of approximately 110 acres which has almost reached saturation development. This subbasin connects into the METRO Interceptor at N. 38th Street and Lake Washington Boulevard. The Kennydale Lakefront sanitary sewer collection system is a low-pressure, force main. Water from Lake Washington is pumped periodically into the force main through Lake Washington flush station. Lake water and the sewage is discharged from this low- pressure force main into the Lake Washington No. 2 Lift Station, where it is then pumped into the METRO East Side Interceptor. The original force main was installed in 1960 and has a history of various problems and requires considerable maintenance. In 1986 the City attempted to improve the collection system through the installation of additional cleanouts on the low-pressure force main and the installation of plug valves on each of the individual side sewers, which could be closed during cleaning operations. This work was conducted under project No. S-442. Upon completion of the additions to the force main and side sewers, the City attempted to clean the low-pressure force main using a sewer pig. Even though the side-sewer plug valves were closed, two homes were flooded out with backed-up wastewater. Since 1986 no further attempts have been made to thoroughly clean the low-pressure, force main. Since this part of the sewer system continues to require high maintenance, the City should continue examining alternatives, that could reduce some of the maintenance and provide a more reliable and efficient system. KENNYDALE SUBBASIN The Kennydale Subbasin serves primarily residential communities including both single- family and multi-family developments. The eastern portion of this subbasin is mostly unsewered at this time. The City has received verbal indication from the King County Health Department of random septic system failures in this area. While the extent of these failures is not known, there is no indication of area or basin-wide problems, but rather localized problems. This subbasin includes two lift stations: the Highgate Lift Station and the Azalea Lane Lift Station. In addition, the Devil's Elbow Lift Station pumps wastewater from the Honey Creek Subbasin to the Kennydale Subbasin. 5-13 CHAPTER FIVE The basin serves approximately 200 acres of the City of Renton, where there is potential for future development and hence higher flow rates. This subbasin was modelled as if the Devil's Elbow and Azalea Lane lift stations were on-line and were pumping simultaneously. the subbasin connects into the METRO East Side Interceptor at Lake Washington Boulevard, south of 28th Street. NORTH HIGHLAND SUBBASIN The North Highlands Subbasin serves a large area of both residential and commercial developments. A major portion of the sanitary sewer system in the North Highlands Subbasin was constructed during World War II. These older sewer systems are near the end of their useful life and require increased maintenance. The Sunset Lift Station pumps sewage from the Honey Creek Subbasin to the North Highlands Subbasin. The North Highlands Interceptor beginning at NE 7th Street and continuing along Sunset Boulevard (approximately 7,200 lineal feet) currently exceeds design capacity. This is primarily a result of receiving wastewater from the Sunset Lift Station. The City's CIP currently has funds targeted for replacing the interceptor, which will increase the capacity of the lower portion of this interceptor. Since wastewater pumped from the Sunset Lift Station is a major factor contributing to capacity problems in the North Highlands Interceptor, additional efforts should focus on constructing the May Valley Interceptor which would provide gravity sewer service to the Honey Creek Subbasin. However, until the May Valley Interceptor is constructed and the Sunset Lift Station is removed from service, the current configuration provides the best solution. NORTH RENTON SUBBASIN The North Renton Subbasin is located on the south end of Lake Washington between the Cedar River and Interstate 405. This subbasin consists of commercial and heavy industrial land uses and includes two lift stations: the Boeing Lift Station and the Lake Washington Beach Lift Station. The North Highlands/North Renton Subbasin serves approximately 600 acres in the City of Renton. Many sections of this basin were not modelled due to a lack of physical data. Severe capacity problems exist within the interceptor along N 6th Street as a direct result of receiving wastewater from the Sunset and Boeing Lift Station. The Boeing Lift Station is planned to be eliminated through the construction of the Park Avenue Interceptor. This subbasin connects into the METRO Interceptor at N 6th Street and Logan Avenue N. 5-14 System Analysis and Results 4. BLACK RIVER BASIN The Black River Basin is a large drainage basin in the southwest part of the City and includes the South Renton, Rolling Hills, Talbot Hill, Renton Industrial, Panther Creek,and Springbrook Subbasins. The higher elevations in the Rolling Hills, Talbot Hill, and Panther Creek areas are generally single-family and multi-family residential developments, while the valley floor is generally industrial and commercial land uses. The Cityserves approximately 3170 acres of this basin. SOUTH RENTON SUBBASIN The South Renton Subbasin includes the commercial business district south of the Cedar River and the residential communities located on the lower slopes of the Rolling Hills. Currently no lift stations are located in this subbasin. Most of the sanitary sewers are in adequate condition and have sufficient capacity for this subbasin; however, older sewers do exist, but are not known to cause problems at this time. Some sewers will need to be relocated as a result of construction on I-405. This will be performed by the Washington State Department of Transportation. ROLLING HILLS/TALBOT HILL/PANTHER CREEK/SPRINGBROOK SUB BASIN The Rolling Hills, Talbot Hill, Panther Creek and Springbrook Subbasin serves the residential communities in the southeast area of the City. This subbasin serves primarily single-family and multi-family communities. The Talbot Hill Subbasin includes the Talbot Crest Lift Station. An agreement is currently being negotiated between Soos Creek Water and Sewer District and the City which will defme service area boundaries and result in joint use of the Springbrook Interceptor which serves the Springbrook Subbasin. The Talbot Road Interceptor which serves a majority of the Panther Creek Subbasin is undersized to service this area. The interceptor should be replaced with larger pipe. RENTON INDUSTRIAL SUBBASIN The Renton Industrial Subbasin includes the area south of Interstate 405 and west of the East Valley Freeway. This area is also called the Orillia Industrial District. This subbasin includes the Lind Avenue and East Valley Lift Stations. Many areas within the subbasin are only sparsely developed at this time. This area was originally developed for light industry and warehousing; however,in recent years the land use has changed rapidly. Increasingly, warehouse type buildings are being converted to office parks, which places increased demands on the existing sewer systems. Consequently, the City should 5-15 CHAPTER FIVE periodically re-examine wastewater flow rates in order to better evaluate sanitary sewer needs. 5. LAKE WASHINGTON WEST BASIN The Lake Washington West is located in the northwest part of the City. The basin is bordered to the east by the Cedar River and to.the south by Sunset Boulevard West. The City serves approximately 710 acres within this basin which consists of primarily single-family and light commercial land uses. This basin primarily transports wastewater east into the METRO East Side Interceptor. This basin is comprised of two subbasins: the West Hill Subbasin and the West Renton Subbasin. Also included in this basin is a portion of the Bryn Mawr-Lakeridge Water and Sewer District and Skyway Water and Sewer District. WEST HILL SUBBASIN The West Hill Subbasin serves the residential communities on the West Hill north of Renton Avenue South. The subbasin includes the Airport Lift Station located at the City of Renton Airport. This is a large subbasin serving approximately 350 acres. Potential for additional development within the city limits in this.subbasin is minimal. Some areas were not modelled in this subbasin due to a lack of physical data. Data which is available is suspect, due to extensive sewer reconstruction, rehabilitation, and the age of the sewers. The sewer system which was modelled appears to have sufficient sewer capacity. WEST RENTON SUBBASIN The West Renton Subbasin serves residential communities west of Rainier Avenue South and the commercial district east of Rainier Avenue South. This subbasin includes the Sears Lift Station and the Earlington School Lift Station. The West Renton Interceptor located in the West Renton Subbasin is experiencing capacity problems along Renton Avenue S. These capacity problems are primarily a result of undersized sanitary sewers, which are serving a large area. Wastewater flows from the Sears and Earlington School Lift Stations are also adversely impacting this interceptor. The existing interceptor is approximately 3,700 lineal feet of 12-inch and 15- 5-16 System Analysis and Results inch sanitary sewer. The City should examine the possibility of increasing the size of this interceptor or providing additional interceptors in this basin. Many sewers are also very old and require replacement, such as the gravity sewers along S 4th Street. 6. DUWAMISH ESTUARY BASIN The Duwamish Estuary Basin is located in the western portion of the City and includes the immediate area surrounding METRO's Renton Treatment Facility. This basin also includes a portion of the Skyway Water and Sewer District. The City serves approximately 580 acres within this basin which primarily consists of light industrial land uses on the valley floor and residential developments on the hillsides. There are no sewer capacity problems which have been identified within this basin. D. LIFT STATIONS This plan evaluated lift stations against the standards and guidelines for construction of sewage lift stations that are detailed in Chapter 3 of the "Criteria for Sewage Works Design" manual prepared by the Washington State Department of Ecology. This chapter includes design standards and guidelines for lift station location, pump sizing and selection, wet well sizing criteria, alarm system, emergency response criteria, force main criteria, lighting and ventilation. These standards and guidelines have been established to ensure protection of the environment and property through design and operation of reliable sewage lift stations. The City of Renton has 23 sewage lift stations, which are shown and inventoried in FIGURE 3. Each station was inspected for safety and accessibility, and operation and maintenance manuals for each were reviewed at the City Shops. The results of these inspections are presented in the following paragraphs, and the lift station inventory summaries are presented in TABLE V-1. Detailed Lift Station Data Sheets are provided in Appendix A. With few exceptions, these lift stations have no major inadequacies in terms of safety or reliability. Most of the lift stations have tone-generated telemetry to the City Shops which activate alarms for high and low wet-well levels, power failure, signal loss and, in some stations, intrusion alarms. LIFT STATION NO. 1 - AIRPORT The Airport Lift Station is located on the east side of West Perimeter Road within the airport property. This facility is a fiberglass, wet well mounted, duplex lift station with a duplex vacuum priming system. This facility serves the airport facility along West 5-17 a b TABLE V-1: LIFT STATION INVENTORY SUMMARY Cii )0 • e.

The lift station is in good condition and has proven to be reliable. An emergency power connection should be installed at this facility. LIFT STATION NO. 2 - AZALEA LANE The Azalea Lane Lift Station is located on the east side of Aberdeen Ave NE, south of NE 24th St. This facility is a fiberglass, wet well mounted, duplex lift station with a duplex vacuum priming system and serves the communities east of the lift station. The lift station is in good condition and has proven to be reliable although it experiences periodic flooding. An overflow pipe connects the storm sewer system to the lift station wet well. As a result, during peak storm events the lift station is required to pump both wastewater and stormwater. The City will examine stormwater problems in this area as part of the Comprehensive Storm and Surface Water Management Plan. One alternative being considered is to constructa stormwater interceptor to serve this area. This lift station will be off-line and removed when wastewater from this area is diverted by gravity through the future East Kennydale Interceptor. LIFT STATION NO. 3 - BAXTER The Baxter Lift Station is located in the J.H. Baxter and Co. pole yard near NE 44th Street adjacent to the railroad tracks. This facility is a recessed, wet well mounted, duplex lift station with a duplex vacuum priming system. The station serves the mill, owned by the J.H. Baxter and Company, and the community along the lake north of NE 44th Street. The lift station is in good condition and has proven to be reliable. There is a creosote smell in the lift station originating from wastewater generated at the mill. Access to this facility is through the pole yard and is made difficult during rainy periods. LIFT STATION NO. 4 - BOEING The Boeing Lift Station is located on the northeast corner of N. 8th Street and Park Avenue N. This facility is a duplex, wet well/dry well lift station and serves the Boeing facilities adjacent the lift station. The lift station is in generally good condition but has poor access and requires a hoist to remove the manhole cover for access. This lift station will be eliminated by constructing a gravity sewer north along Park Avenue N. to METRO's East Side Interceptor in conjunction with the reconstruction of this street. 5-19 CHAPTER FIVE LIFT STATION NO. 5 - COTTONWOOD The Cottonwood Lift Station is located west of the Riviera Apartments, south of the Maple Valley Highway. This facility is a recessed, wet well mounted, duplex lift station. This facility serves the area between the Maple Valley Highway and the Cedar River,east of the Stoneway concrete facilities. The lift station is dangerous and needs to be replaced. The coatings of the mechanical equipment and dry-well walls are in poor condition. The wet well has an overflow bypass to the Cedar River. However, during high river stages, river water can flow into the wet well. As a result, a valve has been installed on the bypass and is manually closed by operation and maintenance personnel during periods of expected, high riverlevels. LIFT STATION NO. 6 - DENNY'S The Denny's Lift Station is located on the east side of Lake Washington Boulevard next to the Denny's restaurant. This facility is a fiberglass, wet well mounted, duplex lift station with a duplex vacuum priming system. This facility serves the Denny's restaurant, is in good condition and has proven to be reliable; however, mechanical equipment needs to be repainted. The lift station does experience some problems due to grease discharges from the restaurant and flooding during peak storm events. LIFT STATION NO. 7 - DEVIL'S ELBOW The Devil's Elbow Lift Station is located at the unimproved intersection of NE 27th Street and 120th Place SE adjacent to Honey Creek. This facility is a wet well mounted, duplex lift station with a duplex vacuum priming system which is housed in a fiberglass building. The lift.station is in fair condition, but is susceptible to vandalism even though the site has a chain-link fence because of its remote location. pumps have had problems holding their prime and the mechanical equipment needs to be repainted. A portion of the force main needs to be replaced due to soil creep along NE 27th Street. This lift station will be taken off-line and removed when the Honey Creek Interceptor and May Valley Interceptor are completed. The Devil's Elbow Lift Station was designed in conjunction with the Honey Creek Interceptor in 1986. According to the Engineering Report, the lift station was intended to be an interim facility until the May Valley Interceptor was constructed. The Honey Creek Interceptor was designed to meet saturation flow conditions from the Honey Creek Basin. However,according to the Engineering Report, the Devil's Elbow Lift Station was designed to meet existing conditions and not to provide a log-term solution for this subbasin. 5-20 System Analysis and Results Each pump within the Devil's Elbow Lift Station is designed for 450 gallons per minutes. The Devil's Elbow Lift Station pumps into the Kennydale Subbasin near the intersection of Edmond s Avenue NE and NE 27th Street. It was determined that wastewater discharged from this lift station would adversely impact the gravity sewers in the Kennydale Subbasin. For this reason, all sewers that were adversely impacted were up- sized in order to handle this additional 450 gallons per minute. In addition a lock-out was put on the Devil's Elbow Lift Station so that both lift station pumps would not pump simultaneously. In recent years, the configuration within the Honey Creek Subbasin has become increasingly problematic. The Devil's Elbow Lift Station was designed to alleviate capacity problems which existed in 1986; increased development within this subbasin has resultedin higher peak wastewater flow rates,causing additional stress to both the Sunset and Devil's Elbow Lift Stations. During peak storm events, wastewater at the Devil's Elbow Lift Station has overflowed into Honey Creek. The pump lock out at Devil's Elbow Lift Station is an additional problem. If a pump within this facility was signaled to operate, but could not because of a malfunction, the pump lock-out would prevent the second pump from taking over. The City maintenance crews can only find out about this problem after the high level alarm at the lift station has been activated. Before further developments occurs in this subbasin, a study should be undertaken to determine alternative to improve system capacity within all of the facilities affected by this deficiency. LIFT STATION NO. 8 - EARLINGTON SCHOOL The Earlington School Lift Station is located on the southwest side of S. Langston Road between S 132nd Street and S 134th Street. This facility is a duplex wet well/dry well lift station with an 8-inch overflow bypass. This facility serves the Earlington Elementary School which is located outside the City limits. The lift station is in good condition, but has poor access and is difficult to keep clean due to its location on the gravel shoulder. The lift station will be taken off-line and removed when wastewater from this area is diverted by gravity through the future Renton Avenue Interceptor. LIFT STATION NO. 9 - EAST VALLEY The East Valley Lift Station is located on the northwest corner of the intersection of SW 34th Street and the East Valley Road. This facility is a duplex wet well/dry well configuration with a single vacuum priming system. This facility serves the commercial 5-21 CHAPTER FIVE areas north and west of the lift station. The lift station is in generally poor condition. The_above-grade electrical enclosures have experienced vandalism, even though the site is enclosed in a chain-link fence. Lift station walls and mechanical equipment need to be repainted. The single vacuum priming system does not allow complete redundancy; this means that the lift station will not operate if there is a failure of the vacuum priming system. Since this lift station is considered to be permanent, it is recommended that this lift station be rehabilitated to make it more reliable. LIFT STATION NO. 10 - FALCON RIDGE The Falcon Ridge Lift Station is located at the east end of SE 8th Street in the plat of Falcon Ridge. This facility is a fiberglass enclosed, wet well mounted, duplex lift station with a duplex vacuum priming system, which is in good condition and has proven to be reliable.

The lift station could be placed back into operation, if required. LIFT STATION NO. 13 - HONEYDEW The Honeydew Lift Station is located in the middle of Union Avenue NE just north of NE 7th Street. This facility utilizes two, non-clogging, submersible pumps. This facility serves the communities north of the Kiwanis Park and Honeydew School along Union Avenue NE. The lift station is in fair condition. However, because it is located in the 5-22 System Analysis and Results middle of Union Avenue, traffic control must be set up to access the lift station. The lift station will be taken off-line and removed when the wastewater from this area is directed by gravity through future developments to the east. These developments, i.e., the Orchards, shouldbe required to-plan for the diversion of wastewater from this lift station through their property. Honeydew Lift Station cannot be taken off-line until the completion of the East Renton Interceptor. LIFT STATION NO. 14 - LAKE WASHINGTON BEACH The Lake Washington Beach Lift Station is located in the parking lot at Coulon Beach Park. This facility is a duplex wet well/dry well lift station which serves the restroom facilities at the park. The lift station is in good condition.

The lift station will be taken off-line and removed when the gravity sewer is completed to NE 4th Street. PRIVATE LIFT STATIONS There are also privately owned and maintained lift stations within the City's service area, which are: Lift Station Location Owner • Pelly Avenue North near North 7th Boeing Company • Rainier Avenue near NW 6th Airport Utility • 148th Avenue SE opposite North 10th (Apollo School) King County Water District No.'90 • East of Kennydale Elementary Private Development • ' Puget Drive near Rolling Hills Private Development • Tukwila Lift Station near METRO plant City of Tukwila i 5-25 CHAPTER FIVE New private lift stations must meet city standards and be required to have a maintenance agreement with the City. This agreement would allow the city maintenance crews to service these private lift stations, at the owner's expense, when neglect has resulted in a health hazard. E. TELEMETRY AND CONTROL SYSTEM Accurate information that details the flow rates in the collection system and trunk lines is paramount to successful system operation and planning. Most of the operation issues, and all of the planning elements, are driven by and based on the flow rates in the pipelines. Without accurate flow rate information, flow rate assumptions must be made based on population _ estimates and industry standard assumptions about per capita sewage contribution,and infiltration and inflow. The accuracy of an analysis is limited if it is based on assumptions only, rather than accurate wastewater flow rate data. To illustrate the importance of accurate flow rate, the following planning and design issues are directly based on flow rates: • The sizes of the pumps in each lift station are based on maximum flow rates in the influent sewer mains. • Collection system, trunk mains, and force mains are based on maximum flow rates from the contributing areas. • Lift station wet well volumes are based on expected influent flow rates and projected emergency reaction times. • Pump run set points are based on providing maximum pump cycle times without allowing the stored sewage to become septic. These are based on influent and pumping flow rates. • The priority and schedule within which facilities are replaced is based on the flow rate capacity of the facility compared with the actual flow rate in the system. Facilities which are operating at or above capacity are replaced first, followed by facilities that are closest to maximum capacity. • Actual system flow rates can be compared with the per capita contribution and pipe material and age to develop relationships between flow rate and population density. Without these relationships, large safety factors must be added to industry standard ratios for per capita flow rates. These, unnecessarily, increase costs or limit development. Without these system-specific ratios,it is also impossible to accurately predict overloaded facilities before the overload shows as surcharged manholes or overflowing wet wells. 5-26 System Analysis and Results Renton's existing sanitary sewer system operates without accurate flow rate information and without adequate maintenance management information. The flow rate data used to develop and calibrate the system-wide computer model was based on industry standards for per-capita flow and land use designations. Although we believe these values are conservative, it is impossible to identify to what extent they are above actual system flow rates. Undoubtedly, they are more conservative in some areas than in others.- This lack of real and accurate data has diminished the ability to identify all potential problem areas, and to develop the most efficient and most cost effective capital improvement program. To date, the operating staff has reacted to system emergencies as they occur, rather than preventing emergencies through an organized, adequate maintenance schedule. To the credit of the maintenance staff, they have performed well with the information available. It would be impossible to improve the maintenance program without additional maintenance management and flow rate information. A properly designed and maintained telemetry and control system includes the following features: Alarm Abnormal Events Provide Engineering Information • Provide Maintenance Information React to System Emergencies Reduce Operating Costs Provide a Convenient Storage Media Schedule Maintenance Tasks Improve Safety Each of these features is discussed in detail below. ALARM ABNORMAL EVENTS Although most sanitary sewer telemetry systems include some alarm information, the following alarms are required for the system to provide the maintenance information necessary to optimize system operation. High wet well level Low wet well level Pump fail (each pump) Low pump flow rate Power fail Fire alarm Telemetry fail Hazardous gas detection 5-27 . I CHAPTER FIVE Water in the dry well Personnel panic alarm Intrusion alarm EMERGENCY INFORMATION Emergency information necessary from the telemetry system must include the influent flow rate to each lift station. This is a calculated quantity based on the length of time it takes to fill a known volume in the wet well. The influent flow rate should be reported as a maximum, minimum, and average value. Pump flow rate is provided by installing an electro-magnetic flowmeter on-the.discharge side of the pumps. Although doppler ultra-sonic meters are commonly used for this purpose,their reliability and calibration are not capable of providing the precise information necessary. -Since each pump discharges through the same flowmeter on alternating cycles, the flow rate difference (difference in pump output) can be used to alarm a pump that is partially plugged or that has worn significantly. The alarm features and flow rate capability of the telemetry system can also be used to identify facilities with a higher than average failure history and to calculate and optimize pump start and stop set points. Pump set points should be calculated to maximize the interval between pump starts, while still maintaining adequate storage reserves in the wet well. These levels should be allowed to automatically change throughout the day to optimize pump run times. In addition, the telemetry system should track and store flow rate trends to be used for engineering and planning purposes. MAINTENANCE INFORMATION The telemetry system must automatically track and display pump efficiency at each lift station. This is accomplished by measuring flow rate and electrical current and calculating the efficiency of each pump cycle. The maintenance staff uses pump efficiency to identify pumps that are near the end of their service life and need tobe replaced,or pumps that are plugged or partly plugged and need service attention. In addition, the system should continuously monitor,calculate and display the high level response time at each wet well in the system. The response time continuously varies depending on the influent rate and the volume above the alarm level in the wet well, and it is useful in determining the sequence of reactions to multiple high level alarms. During a multiple alarm episode, the staff can respond to the wet well with • the shortest, high level response time. The failure history of,each lift station should be monitored to identify recurring problems or chronic failure sites. This information is then used to identify frequency of maintenance per site and when facility replacement is due. 5-28 System Analysis and Results REACT TO SYSTEM EMERGENCIES The telemetry system should be configured to automatically react to some system emergencies. For example, lift stations in series should be locked out if a receiving lift station has a high level alarm. If an overflow is unavoidable, the station that causes the least damage should be allowed.to overflow first to provide additional reaction time for maintenance personnel. Low-flow detection should cause the second pump to, start, therefore, providing standby pumping without waiting for a high level alarm. Multiple failures or alarms occurring simultaneously can be prioritized by the telemetry system based on holding capacities and overflow damage potential in order to direct maintenance personnel to the most critical sites first. An intelligent callout system can direct on-duty personnel directly to the necessary lift station without the need to go to the central control panel first,thus, saving emergency response time. An automatic gas detection system can be used to alert operating personnel of a hazardous condition before they enter the lift station facility. REDUCE OPERATING COSTS Operating costs can be reduced by a properly configured telemetry and control system. A central display of lift station and collection system operating data can be monitored by a single person during high system stress conditions to react to problems or emergencies before they are alarmed. The system can be used to alarm pumps that are operating at low efficiency, and the pump run times and starts can be monitored to identify components that need repair or replacement. This database can be used with the City's existing maintenance program to develop failure history at each lift station and to identify a "mean time between failures" for Renton's system. Efficiency can also be compared with flow rates and failure histories to develop pump start and stop set points that optimize pump run times and minimize pump operating costs. The data logging features of the telemetry system can be used to perform data collection that is currently accomplished manually, which will allow maintenance personnel to concentrate on maintenance and operation tasks. CONVENIENT STORAGE MEDIA A computer telemetry system provides an efficient media for storing operating data, management and engineering data, and maintenance information. In order for the data to be most useful, it must be time stamped and stored in ASCII text format. This allows any historical period to be recalled and imported into City standard spreadsheet programs for manipulation. Data, which is summarized or condensed before it is stored, loses resolution and the ability to be manipulated to develop engineering and maintenance 5-29 CHAPTER FIVE relationships. The storage format should be compatible with the water telemetry system so that the equipment can be interchanged and one system used as a backup to the other. SCHEDULE MAINTENANCE TASKS Any telemetry system should be compatible with the City's existing maintenance management system, and the database should be configured to provide real-time operating information to the maintenance system. Pump maintenance should be based on the total running time of each pump and the number of starts of each pump. This information is available through the telemetry system. Each lift station and each pump combination has its own characteristic maintenance requirements. Some pumps may require maintenance every 1,000 hours others every 15,000 hours depending on the service and duty conditions in each facility. Real time operating information can provide the maintenance system with the proper data to develop the necessary maintenance requirements at each site. This procedure results in the most efficient use of the maintenance staff's time and reduces overall operating costs. In addition, it eliminates the most frequent sources of equipment failures. IMPROVE SITE SAFETY The telemetry system should continuously monitor hazardous gases in the dry well and alert operating personnel of unsafe conditions. A personnel panic alarm at each site should be used for added operator safety. A central reporting of the occupied lift stations allows the maintenance managers to locate and track the maintenance crews for added safety and reliability. • 1. EXISTING TELEMETRY SYSTEM The City currently owns and operates an analog, signal-based alarm reporting system, manufactured by Stead & Baggerly of Bellevue, Washington, which monitors each lift station. The system includes a master console that is located in the City Shops, and a remote telemetry transmitter located in each lift station. The master console is in continuous contact with most lift stations via dedicated telephone wires and circuits. Telemetry tone transmitters in each lift station report the operating status of the lift station pumps and alarm events. The following data is telemetered and displayed at the Master Console: 5-30 System Analysis and Results Component Status Pump 1 Run Pump 2 Run Wet Well High Level Alarm Station Power Fail Alarm conditions are transmitted to on-call maintenance personnel using automatic telephone dialer. Although this system has operated reliably, it does not generate the information necessary to optimize operation of the lift station facilities and the collection system. The leased telephones are expensive and are not regularly maintained by the telephone company. The existing system is not easy to troubleshoot or repair, and must be maintained by an independent contractor. The current system does not measure or record flow rate, includes no redundancy, has no data Iogging, no maintenance management information, and no control capability. 2. PROPOSED SYSTEM IMPROVEMENTS The Renton Sanitary Sewer System needs a new comprehensive Telemetry and Data Logging System. The system should be used by the engineering staff to verify or modify the flow rate assumptions made in this plan and to identify additional improvements necessary. The maintenance staff will use the system to reduce costs, improve reliability and increase safety. The new system must be digital, signal-based, using a high security, binary coded decimal for telemetry transmission. The system should run on IBM compatible computers and use smart remote telemetry units at the lift stations and collection system monitoring points. Telemetry should be a combination of leased telephone line and radio transmission, with the radios being the preferred transmission media. Because the lift stations are often located at the bottom of drainage basins, radios may not work at all sites. These sites should use leased telephone lines for data transmission instead of radios. Control of the facilities should be accomplished in a distributed format, wherein the control computer provides pump run set points that are based on optimal,pump operating conditions, and also locks out various lift stations during high-level alarms from various downstream lift stations. All other control is initiated from the Remote Telemetry Unit, including pump start/stop from the level transducer, back-up pump control from the float switches and station alarms. The system should use strain-gauge, level transducers that are suspended in the wet well for primary pump control, and use float switches for back-up pump control in the event of transducer failure. Pump discharge flow rates should be measured using an electro-magnetic flowmeter. 5-31 CHAPTER FIVE Influent flow rates do not need to be measured directly, but rather can be mathematically synthesized by measuring the time it takes to fill a known volume of the wet well. The engineering and system status information that is presented at the City Shops should also be displayed in real time format at City Hall using a networked data logger computer. This will allow the engineering and planning staff access to system information without disrupting the maintenance staff. The computer and data storage system should be compatible with the existing water data logger to provide redundant data storage and to provide hot standby fail over controllers. The system should also be integrated with the existing maintenance management system to provide real time operating data and failure history data to the maintenance system. Each remote telemetry unit, located in each lift station, should include intelligent telephone dialer alarm systems, so that critical alarms can be relayed to on-duty maintenance personnel, even during a telemetry system failure. Telemetry and control should be provided at each lift station in the system, and at strategically located, collection system flow-metering points. A pre-design report should be developed in conjunction with the telemetry system replacement design to identify the number and location of flow metering stations. F. WASTEWATER QUALITY The quality of wastewater transported in the Renton sanitary sewer system varies considerably depending on the wastewater source, detention time within the sanitary sewer system and the volume of infiltration and inflow. This chapter discusses several aspects of wastewater quality and will recommend measures to control or eliminate wastewater quality problems. 1. DOMESTIC WASTEWATER The quality of domestic wastewater varies and is a direct result of the type of water used within the home. Some domestic sewage can be considered stronger than others. One household appliance, the garbage disposal, can greatly impact the quality of wastewater. Most new home construction incorporates garbage disposal in its design. Use of these garbage disposals increases both suspended solids and the biochemical oxygen demand (BOD), two common results tested for when measuring contaminant concentrations. A second major determinant of quality of wastewater is the volume of infiltration and inflow into the sewer system. High rates of infiltration and inflow will tend to dilute the contaminant concentration of the wastewater. 5-32 System Analysis and Results 2. INDUSTRIAL WASTE Industrial wastes deserve special attention because they can exhibit a wide variety of chemical constituents. The total volume of industrial waste produced within the City of Renton is small compared with the volume of domestic wastewater. However, an industrial or commercial development can have a considerable impact on the sanitary sewer collection system immediately downstream of the facility. Industrial waste can contain high concentrations of chemicals which can make the waste highly corrosive or toxic. A list of the industries located within the City of Renton is provided in TABLE V-2. If discharge of an industrial waste to the sanitary sewer system creates problems, then pretreatment of the industrial waste should be considered. Several federal and state regulations govern the pretreatment of industrial waste. Several industries within the City have obtained National Pollution Discharge Elimination Systems (NPDES) permits as noted in TABLE V-2. The City should assume that those who require permits have them and should rely on the Department of Ecology to fulfill its monitoring responsibilities. According to Department of Ecology records, no violations of NPDES permits involving sanitary sewer discharges have been reported recently. 5-33 CHAPTER FIVE TABLE V-2: COMMERCIAL AND INDUSTRIAL WASTEWATER PRODUCERS INDUSTRIES ADDRESS PERMITS WASTES - Boeing Airplane N 8th and Logan N NPDES Chemicals Company WA0002992 Dotz Chemical 113 S Tillicum Detergents Products Florillo Northwest 100 Blaine Ave. NE Chemicals Acme Processing, 600 SW 7th Street NPDES High BOD Solids - Inc.

WASTEWATER QUALITY PROBLEMS A major problem associated with wastewater quality is the generation of hydrogen sulfide that occurs during wastewater transport from its source to the point of treatment. The hydrogen sulfide found in wastewater results from the anaerobic bacterial reduction of the sulfate ions that are present. Hydrogen sulfide poses three serious problems: it is highly corrosive, has an obnoxious odor, and as a gas is toxic to humans and has beenknown to cause death to sewer maintenance workers. The production of hydrogen sulfide is directly related to the biochemical oxygen demand (BOD) of the wastewater. Wastewater exhibiting a high BOD will tend to generate more hydrogen sulfide than wastewater exhibiting a lower BOD; therefore, excessive infiltration and inflow will tend to reduce the production of hydrogen sulfide in the wastewater. Hydrogen sulfide is very corrosive to both sewers and pumping facilities. Hydrogen sulfide released from the wastewater will tend to dissolve on condensation within the crown of a sanitary sewer. The hydrogen sulfide retained in the condensation is converted to sulfuric acid through oxidation by aerobic bacteria. This sulfuric acid will react with the cement bonding material within concrete pipes, or iron within steel pipes, and can corrode a pipe to the point of structural 5-34 System Analysis and Results failure. Sanitary sewer pipes are most susceptible to this type of corrosion in their crowns because that is where most condensation occurs. Effects of hydrogen sulfide can be controlled by aeration, periodic cleaning, and use of noncorrosive pipe materials. If excessive hydrogen sulfide production is evident at a lift station, aeration of the wet well should be considered to reduce the hydrogen sulfide in the wastewater and reduce the effects of anaerobic bacteria which produce the hydrogen sulfide. Periodic cleaning of the sanitary sewers will also remove the biological slime that forms on the pipe walls and produces the hydrogen sulfide. The most effective method of mitigating corrosion by hydrogen sulfide is through the use of noncorrosive pipe materials, such as polyvinyl chloride (PVC), or high density polyethylene (HDPE). Existing pipes experiencing severe corrosion can be rehabilitated through the use of various slip form liners or fiberglass resin liners. In order to control the generation of hydrogen sulfide, the City's maintenance crews routinely flush and clean sewer pipes with inadequate slopes. In addition, all pipes are cleaned before video inspection is performed. Both of these tasks reduce biological growth on the walls of the sewer pipes and reduce the hydrogen sulfide generation potential. 5-35 CHAPTER VI SYSTEM IMPROVEMENTS a CHAPTER VI CONCLUSIONS AND IMPROVEMENTS A. INTRODUCTION This chapter presents the proposed improvements to the Renton sewer system that are necessary to correct'existing deficiencies and accommodate growth. The costs of the improvements and a schedule for implementing them are also included. This Capital Improvements Program is designed, along with the entire comprehensive plan, to be used as a guideline in preparing the capital improvements project list during each yearly budget process. This plan is deliberately intended to be flexible by allowing incorporation of necessary changes that might arise. Many of the proposed improvements are considered to be preventive in nature, i.e., the improvement is intended to happen before a specific facility has failed, a far more desirable process than trying toreplace facilities after they fail. Since it is impossible to estimate when a facility will fail, the process of identifying those facilities which are at risk and planning corrective measures must continue. B. CIP RANKINGS The complexity of the City's wastewater utility system requires .a method that systematically determines which improvements should be undertaken sooner than others. To assign rankings to the planned improvements, each one was analyzed according to these general categories: Substandard .Facility, System Efficiency, Environmental Protection. Each category was further divided into four or more kinds of improvements or standards. Each of these subcategories was assigned a number of points, with the rule that no one improvement could be given more than eight points in any of the three categories. For each subcategory,each proposed project was given one point if it provided the benefit described and two points if it provided a solution to an acute problem. The higher the number of points an improvement received, the greater its benefit, or the greater its ability to meet certain standards or policies. This systematic ranking will help direct resources and activities to the appropriate projects. 1. SUBSTANDARD FACILITY A facility qualifies as substandard if it is unreliable, is structurally deteriorating or has hydraulic capacity problems. A project received points if it resulted in the following improvements to a substandard facility: POINTS: 1-2 Reduces or eliminates hydraulic capacity problems. 1-2 Replaces a deteriorating facility or corrects a structural problem.. 6-1 CHAPTER SIX 1-2 Improves system reliability (i.e., prevents discharge of raw sewage • to any waters, or reduces the potential backup of raw sewage into basements, streets, or other properties). 1-2 Corrects occupation hazard (i.e., reduce dangers to maintenance workers). Maximum Number of Points: 8 2. SYSTEM EFFICIENCY A project can improve the efficiency of the system if it results in a reduction of operation and maintenance costs. Examples of such projects include wastewater flow rate modeling and elimination of lift stations. A project received points for system efficiency if it met any of the following conditions: POINTS: 1-2 Involves improving lift station operation or efficiency. 1-2 Involves the elimination of a lift station. 1-2 Reduces infiltration and inflow. 1-2 Improves understanding and planning of sewer system. Maximum Number of Points: 8 3. ENVIRONMENTAL PROTECTION An improvement helps protect the environment if it reduces damage to it, or reduces the threat to the public health. Examples of deficiencies that such projects improve include: failing septic tanks or sewage overflows into lakes or streams. An improvement received points for environmental protection if it met any of the following conditions: POINTS: 1-2 Eliminates septic tanks. 1-2 Improves protection of the public health and safety. 1-2 Improves protection of the environment (i.e., land, wetlands, streams, groundwater). 2 Helps protect Zone 1 of Aquifer Protection Area. 1 Helps protect Zone 2 of Aquifer Protection Area. Maximum Number of Points: 8 The results of the systematic ranking are presented in TABLE VI-1. After completion of the ranking analysis, the projects were sorted and statistically divided into quartiles (fourths). The first quartile (Quartile I) were those projects with rankings above the 75th percentile. The second quartile (Quartile II) were those projects with rankings between the 50th and the 75th percentiles. The third quartile (Quartile III) were those projects 6-2 Conclusions and Improvements TABLE VI-1: RANKING SUMMARY OF PROPOSED IMPROVEMENTS PROJECT PROPOSED CAPITAL IMPROVEMENTS Substandard System Environmental Total QUARTILE NUMBER Facilities Efficiency Protection Ranking MAY CREEK BASIN 1.1 Devil's Elbow Lift Station Rehabilitation 4 1 5 10 I 1.2 Devil's Elbow Force Main Repair 4 1 5 10 I 1.3 May Valley Interceptor,Section 2 6 2 6 14 I 1.4 Honey Creek Interceptor,Phase IV 6 2 6 14 I 1.5 Sierra Heights Sewer System Construction 2 1 7 10 I 1.6 Sunset Lift Station Elimination 5 1 4 10 I 1.7 Devil's Elbow Lift Station Elimination 4 1 4 9 II 1.8 Misty Cove and Baxter Lift Station Rehabilitation 2 1 1 4 N 1.9 Denny's Lift Station Rehabilitation 1 1 2 N J,OWER CEDAR RIVER BASIN 2.1 East Renton Interceptor 4 2 5 11 I 2.2 Interim Moratorium Area Improvements 4 2 5 11 I 2.3 Cottonwood Lift Station Replacement 6 2 6 14 I 2.4 Central Renton Sewer Replacement,Phase I(Pelly/Garden) 5 2 6 13 I 2.5 Central Renton Sewer Replacement,Phase II(Williams/Pelly) 5 2 6 13 I 2.6 Central Renton Sewer Replacement,Phase III(Houser/Factory) 4 1 4 9 II _ 2.7 Highlands Sewer Replacement,Phase III 3 1 3 7 II 2.8 South Highlands Interbasin Transfer 4 3 7 II 2.9 Honeydew Lift Station Elimination 3 1 3 7 II 2.10 Union 600 Lift Station Elimination 2 1 3 6 III 2.11 Falcon Ridge Lift Station Elimination 2 1 3 6 III 2.12 NE 7th Place Sewer Replacement 2 3 5 N LAKE.WASHINGTON EAST BASIN 3.1 Lake Washington No.2 Lift Station Replacement 5 2 3 10 I 3.2 West Kennydale Interceptor 2 1 5 8 II 3.3 Highlands Sewer Replacement,Phases I&II 5 1 3 9 U 3.4 Highgate Lift Station Elimination 3 1 3 7 II 3.5 East Kennydale Interceptor 2 1 4 7 II 3.6 Azalea Lane Lift Station Elimination 2 2 3 7 II 3.7 Keffiydale Lakefront Sewer System Study 3 1 2 6 III 3.8 Park Avenue Interceptor 3 1 2 6 III 3.9 Boeing Lift Station Elimination 3 1 2 6 III 3.10 North Renton Sewer Replacement,Phase I(Wells/Park) 3 1 2 6 III 3.11 North Renton Sewer Replacement,Phase II(Logan/Well) 3 1 2 6 III AT Ant RIVER BASIN 4.1 Renton CBD Sewer Replacement,Phase I(Mill Avenue) 4 1 4 9 II 4.2 Renton CBD Sewer Replacement,Phase II(Logan/Williams) 3 1 3 7 II 4.3 Talbot Crest Lift Station Elimination 3 1 2 6 III 4.4 SW 34th Street Interceptor Replacement 2 1 2 5 N 4.5 East Valley Lift Station Rehabilitation 2 1 2 5 N 4.6 Lind Avenue Lift Station Rehabilitation 2 1 2 5 N 4.7 Talbot Road Interceptor Replacement 2 1 2 5 N JAKE WASHINGTON WEST BASIN 5.1 Renton CBD Sewer Replacement,Phase III(S.4th Street) 4 1 2 7 II 5.2 Renton Avenue Interceptor 2 1 1 4 IV 5.3 Earlington School Lift Station Elimination 3 1 2 6 III 5.4 Sears Lift Station Replacement 2 1 2 5 IV 5.5 Airport Lift Station Rehabilitation • 2 2 4 IV DUWAMIS}3 ESTUARY BAftrst 6.1 IBlack River Interceptor 1 1 IV ,SYSTEM WIDE IMPROVEMENTS 7.1 Telemetry and Data Logging System Replacement 3 2 2 7 II 7.2 Infiltration and Inflow Testing and Monitoring Annual 7.3 Existing Sewer Grouting Annual 7.4 Miscellaneous Sewer Replacement Annual 6-3 CHAPTER SIX with rankings between the 25th and the 50th percentiles. The fourth quartile(Quartile IV) were those projects with rankings below the 25th percentile. These project rankings cannot be used solely to prepare the Capital Improvement Program. The project rankings do not take into consideration engineering judgment or scheduling of dependent projects. Engineering judgment involves the trained observation of non-quantifiable impacts of a project. The scheduling of projects involves determining which projects must be completed before other projects can begin. For these reasons, the project ranking is best used as one of many tools to establish a Capital Improvement Program. TABLE VI-2 presents the project priority along with brief comments regarding any inconsistency between the project quartile and the project priority. C. CAPITAL IMPROVEMENT DESCRIPTIONS A list of all the proposed capital improvements, organized by drainage basin, follows. A brief description of the specific system deficiency and its improvement are included. System improvements are presented in this chapter in the following order: • A list of each proposed improvement by basin with a brief description of the criteria used, the estimated current cost of the improvement,and the recommended years for construction. • A summary of improvements by priority (TABLE VI-3). • A summary of improvements by project type (TABLE VI-4). • A summary of the estimated project costs and a schedule for implementation.

MAY CREEK BASIN Devil's Elbow Lift Station Rehabilitation System Deficiency: Construction of the Devil's Elbow Lift Station was completed in 1986. However, significant mechanical difficulties have made the lift station unreliable. In addition, excessive vandalism has occurred due to the lift station's remote location. During peak, wet-weather flows, the Devil's Elbow lift station has overflowed into Honey Creek. The lift station operation must be made more reliable and the facility must be made more resistant to vandalism. Improvement: Correct mechanical problems with lift station in order to meet current design standards. CIP Project No. 1.1 Cost: $167,000 Priority A Beginning: 1991 Completion: 1991 Devil's Elbow Force Main Repair System Deficiency: Northeast 27th Street has been closed to automobile traffic due to the unstable side slopes of the Honey Creek ravine. The force main for the Devil's Elbow Lift Station, which is located on NE 27th Street has the potential of structural failure if the side slopes supporting the roadway were to deteriorate further. Reconstruction of several sections of the force main is required to increase its reliability. Improvement: Correct instability problems with force main to ensure reliability. CIP Project No. 1.2 Cost: $75,000 Priority A Beginning: 1991 Completion: 1991 6-6 Conclusions and Improvements May Valley Interceptor, Section 2 System Deficiency: The May Valley Interceptor is a facility that is proposed to be constructed.by METRO to serve the sewerage needs of this basin. Section 1 of the May Valley Interceptor has been constructed from METRO's. East Side Interceptor under Interstate 405 to Jones Avenue NE. Section 2 would extend south along Jones Avenue NE which parallels May Creek to Honey Creek. At this time METRO intends to construct Section 2 of the May Valley Interceptor. However, the City may need to take the initiative to construct the May Valley Interceptor, Section 2, if METROs schedule does not coincide with the City's needs. Construction of Section 2 of the May Valley Interceptor is necessary to complete the Honey Creek Interceptor and eliminate the need for the Sunset and Devil's Elbow Lift Stations. The May Valley Interceptor, Section 2, would require approximately 5,400 lineal feet of 24-inch gravity sewer. Improvement: Construct gravity sewer service in the May Creek Basin to Honey Creek CIP Project No. 1.3 Cost: $1,448,000 Priority A Beginning: 1991 Completion: 1993 Honey Creek Interceptor, Phase IV System Deficiency: Phases I through III of the Honey Creek Interceptor were completed in 1986. However,frequent mechanical problems with the Devil's Elbow Lift Station and structural problems with the Devil's Elbow force main require that a long-term solution be developed for this basin. The solution is the completion of the Honey Creek Interceptor,Phase IV,which would provide a gravity interceptor from the existing Devil's Elbow Lift Station down to the mouth of the Honey Creek.. In conjunction with this project, the May Valley Interceptor, Section 2, must be completed. Honey Creek Interceptor, Phase IV, would require approximately 2,700 lineal feet of 12-inch gravity sewer. Improvement: Complete construction of the Honey Creek Interceptor in order to eliminate the Devil's Elbow and Sunset Lift Stations. CIP Project No. 1.4.

SANITARY SEWER SYSTEM OPERATION A comprehensive maintenance program allows the City to optimize its use of the existing collection system and pumping facilities, thereby extracting the maximum life and capacity of each facility. This permits the same facilities to accommodate greater flow rates and more system connections while minimizing construction of new facilities. A properly maintained facility is less likely to fail. This reduces the operating costs of the utility because of lower damage compensation costs and overtime costs for maintenance personnel. It also protects the environment.and the public health by minimizing sewage overflows. B. CURRENT OPERATION AND MAINTENANCE PROGRAM The current operation and maintenance program for the sewer utility is discussed in this chapter. • The operation and maintenance program consists of four elements: Normal Operations Emergency Operations Preventive Maintenance Staffing 1. NORMAL OPERATIONS Normal operation of the sanitary sewer utility is a combination of interaction between the Wastewater Utility Section (located in City Hall) and the Operation and Maintenance Division (located in the City Shop Facility). a. ORGANIZATIONAL STRUCTURE The sewer utility operates under the direction of the Administrator of Planning, Building and Public Works, Ms. Lynn Guttmann. The Sanitary Sewer Operation and Maintenance Division is supervised by Mr. Gary Morrison who reports to the Field Maintenance Supervisor, Mr. Jack Crumley. The Wastewater Utility Section is supervised by Mr. Randall Parsons who reports to the Utility Systems Division Manager, Mr. Richard Anderson. Mr. Jack Crumley and Mr. Richard Anderson report to Ms. Lynn Guttmann. The certifications based on successful completion of training courses and examinations held by the Operation and Maintenance and Engineering staff are listed in TABLE VII-1. Training consists of special courses and seminars specifically designed for the requirements of sanitary sewer utility employees. The training is offered through such organizations as the APWA 7-1 CHAPTER SEVEN TABLE VII.1: CITY PERSONNEL AND CERTIFICATION OPERATION AND MAINTENANCE PERSONNEL PERSONNEL POSITION CERTIFICATION RESPONSIBILITIES Gary Morrison Supervisor Wastewater Collection III Oversees and manages sanitary sewer system operation and maintenance.

Dave Jennings Stormwater Civil Engineer II Manages the Infiltration and Inflow Engineer Engineer-in-Training Program for the Wastewater Utility for about 10 percent of his time(other 90 percent of his time is spent with his regular duties in the stormwater utility). 7-2 Operations and Maintenance (local section), various trade organizations, local colleges.and universities; Seattle-King County Health Departments, other sewer utilities, and by industrial training specialists. Renton's policy of supporting and promoting operator'training should be continued. As the complexity of the system increases and as the service area expands, the need for trained, efficient staff to keep pace with public demand and advances in technology will become imperative. New employees need orientation and basic information, while more experienced employees can improve by continued training. Training opportunities are of such importance to effectively operating the system that Renton has linked them to its overall personnel evaluation program. Employees are evaluated and promoted through a set of job categories that are increasingly well paid. It is essential that the promotional program continue to be closely linked with the training program, not only because it promotes efficient operation, but because mandatory certification of wastewater utility workers is required by the state. Qualifications and training requirements for obtaining and maintaining certification are stipulated by the State Department of Health. The City Council and Administration have approved expenditures for increased training with the result that improved proficiency levels have occurred in the last five years. b. COMMUNICATION Efficient and economical functioning of a team requires adequate provision for regular, effective communication among its members. The normal channels of communication available to maintain effective coordination are: Vehicular two-way radios Regularly kept work logs Regular inspection reports Daily work assignment meetings Inventory and other record keeping practices Emergency phone numbers for "on-call" employees Direct, City owned telephone connection to City Hall Weekly staff meetings The sewer utility does not have a comprehensive system operation manual; however, lift station facility operation and maintenance manuals are available for staff reference. City staff have maintained the policy of requiring complete operation and.maintenance manuals for all new equipment and facilities. In addition, we recommend that a system wide Operations and Maintenance manual, including emergency response procedures, be prepared and updated on a regular basis. 7-3 CHAPTER SEVEN c. EQUIPMENT AVAILABILITY Sewer maintenance staff is equipped primarily with rented equipment. The equipment available for daily use includes rolling stock, shop tools and incidental equipment as well as other portable equipment for field use. The vehicles and other rolling stock are listed in TABLE VII-2 with a description of their primary use in the department. A description of each vehicle and its uses is presented below. The existing inventory appears adequate at current staffing levels but should increase in proportion to customer increases. The City should examine the backup capabilities of the inventory, based on critical equipment or facility failure, and make provisions for additional material procurement on a short notice basis where necessary. TABLE VII-2: WASTEWATER UTILITY DEPARTMENT EQUIPMENT(1989) ROLLING STOCK Vehicle# Year Vehicle Description C-75 1976 Utility TV inspection unit D-58 1987 Lift station utility truck D-51 1987 Manhole and line service truck E-71 1986 Aquatech high velocity sewer jet and vacuum unit S-91 1976 Mechanical rodding OTHER EQUIPMENT Amount Equipment Description 4 Wacker compactors 1 3-inch trash pump 4 Trash diaphragm pumps 1 Chainsaw 1 Set of emergency lighting 1 Emergency generator 7-4 Operations and Maintenance UTILITIES T.V. INSPECTION UNIT EQUIPMENT #C-75 This unit is a closed-circuit T.V. system used for inspecting underground utility lines, primarily sanitary sewer and storm drain lines. It is fully self-contained with a generator, compressor, and water supply. Its primary use is to determine conditions of existing lines and any repairs or replacement necessary. The T.V. van is an important part of the maintenance program to help determine priority areas that require further attention and maintenance. LIFT STATION UTILITY TRUCK EQUIPMENT #D-58 , This vehicle is used by the lift station crew for inspection, maintenance and repair of sewer pump stations. It is equipped with a crane used for lifting pumps and equipment as needed, and utility compartments for parts, tools, etc. This vehicle is also used to transport the mechanical rodding machine and to assist with other maintenance procedures as needed. MANHOLE AND LINE SERVICE TRUCK EQUIPMENT #D-51 This vehicle is used by the line crew for inspection and repair of manholes and lines. It is equipped with a crane hoist for lifting and setting manhole rings and equipment used in repair work. It carries parts used in sewer line repair such as couplings, fittings, plugs, etc. It is also equipped with an auxiliary hydraulic power unit that operates jackhammers, compactors, and pumps malting this vehicle self-contained for exposing and excavation procedures. AQUATECH HIGH VELOCITY SEWER JET AND VACUUM UNIT EQUIPMENT EQUIPMENT #E-71 The Aquatech has a wide variety of uses in the utility maintenance programs. It is primarily used to clean sewer lines and remove solid debris (i.e.,rocks, silt, dirt) from the lines that could create flow restrictions and blockages. There are a number of lines in the City, primarily in the downtown area, that have inconsistent grades creating septic conditions within the lines. A part of the maintenance program is to use the Aquatech to flush water through these particular lines periodically to prevent those conditions from occurring. The Aquatech is the primary equipment used for emergency blockages in the lines and is used to assist T.V. inspection by setting cables. 7-5 CHAPTER SEVEN MECHANICAL RODDING MACHINE EQUIPMENT #S-91 The mechanical raider is used to remove roots and grease that accumulate within sewer lines creating flow restrictions and blockages. Numerous lines throughout the City have been examined and discovered to.have had 'a history of problems created by roots and grease. These particular lines are rodded periodically to ensure there is no interruption of flow. d. ROUTINE OPERATIONS Routine operations involve the analysis,formulation, and implementation of procedures to ensure that the sanitary sewer facilities are functioning efficiently. The utility's maintenance procedures are good, with repairs being made promptly so customers do not experience unnecessary inconvenience. Side sewer maintenance can be a major problem within a sanitary sewer system. Side sewers are owned and should be maintained by the individual property owners. City policy is that individual property owners are responsible for maintaining their side sewers. If a problem occurs, the property owner is to contact a private plumber to investigate and correct the problem. If the property owner can show that the problem is within the publicly owned sewer main, then the City will correct the problem and reimburse the property owner for expenses incurred. e. RECORDS Providing time for keeping and maintaining accurate records should be an integral consideration in determining the time to be allotted to any departmental task. Adequate records are an essential tool in utility management and operation,providing the supporting data for operations assessment and long-term planning, while saving time and reducing difficulty when trouble arises. The sewer utility has need for several types of records: facility operation, records, personnel, customer contact, inventory, and facility maintenance and repair. These and other appropriate documents should be legible, concise, permanent, accurate and accessible. Their importance to the efficient functioning of the utility is critical. Up-to-date maps of the sanitary sewer system are important for operation and maintenance. Changes or additions to the sanitary sewer system should be added as they occur. The City maintains an updated 1"= 400' scale map of the sanitary sewer system that is useful to the operations and maintenance staff. These utility maps show the sanitary sewer size and location, manhole location and number, cleanout location, and lift station and force main locations. As- 7-6 Operations and Maintenance built drawings of much of the existing sanitary sewer system are kept on file in the Utility r• Systems Division at City Hall. This information is useful in helping the operation and maintenance staff to locate sanitary sewer lines and service connections from these drawings. Plat maps or construction drawings for new sanitary sewer extensions within the distribution system should continue to be kept for the sanitary sewer system. 2. EMERGENCY OPERATIONS The City responds to emergencies involving the sanitary sewer system through the use of on-call personnel. The Sanitary Sewer Department does not have an emergency response plan that identifies,how Renton should react to an emergency. It is recommended that the City prepare an emergency response plan for the sewer utility. This plan should include the functions and responsibilities of personnel, procedures to be followed, maps of each facility, contact lists, and communication procedures. The emergency response procedures should be available both in report form and through a computer program prepared specifically for that purpose. The emergency response plan should be updated every two years. C. PREVENTIVE MAINTENANCE Maintenance schedules that meet or exceed manufacturer's recommendations should be established for all..critical components in the sanitary sewer system. The following schedule should be used as a minimum for preventive maintenance: Sewage Lift Stations Daily: Observe and record motor current draw; check packing; log and record pump motor hours; check motor noise, temperature, vibration. Weekly: Check security. Semiannually: Change motor oil. As Needed: Recoat structures and piping; maintain electrical and hydraulic controls. Wet Well Facilities Weekly: Check security: Check float settings. Annually: Check interior condition,ladder,hatches,etc.,in wet well. As Needed: Recoat interior as needed in wet well (estimated 10- to 15-year frequency). Sanitary Sewer System Twice Per Week: Check inspection manholes for flow reduction. Clean lines when flow in sewers is reduced. 7-7 CHAPTER SEVEN • Semiannually: Cut roots in sewers with root problems. Tools & Equipment 1. Rolling Stock Daily: Check all fluid levels and brakes. As Needed: Replace fluids and filters in accordance with manufacturer's recommendations (or more frequently depending on type of use). 2. Tools As Needed: Clean after each use; lubricate and maintain as necessary. D. STAFFING The preventive maintenance procedures and normal as well as emergency operations of the utility are described in the previous sections. The hours of labor and supervisory activity required to effectively carry out the work of these on-going maintenance and operations schedules and engineering responsibilities form the basis for determining adequate staffing levels. 1. MAINTENANCE AND OPERATIONS STAFF The current staff organization is illustrated in TABLE VII-1. There are at present seven employees, including supervisory personnel and maintenance workers,who operate and maintain the sanitary sewer system. The tasks that are performed by sewer utility staff include inspection, testing, installation and repair of system facilities and routine preventive maintenance, record keeping, administrative tasks, and corrective action required in response to emergencies. The hours of work required to adequately maintain the sanitary sewer system are shown in TABLE VII-3. For preventive maintenance alone,the annual hours total 3,589, or 69 crew hours per week. This requires nearly 2 crew members working full time, i.e., 40 hours per week, excluding vacation, sick leave, and all other tasks not related to preventive maintenance. The hours of work required for operational tasks for the sanitary sewer system are shown in TABLE VII-4. For operational tasks alone, the annual hours total 8,535, or 164 crew hours per week. This requires more than 4 crew members working full time, i.e., 40 hours per week, excluding vacation, sick leave, and all other tasks not related to operation of the sanitary sewer system. The total operation and preventive maintenance time required is 12,124 hours per year, which is equivalent to six people working full time, 40 hours per week. 7-8 Operations and Maintenance TABLE VII-3: STAFFING TIME FOR PREVENTIVE MAINTENANCE FACILITY OR FREQUENCY OF QUANTITY IN TIME REQUIRED EQUIPMENT MAINTENANCE SYSTEM TIME PER UNIT PER YEAR Lift Station Annually 22 Stations 16 Manhours 352 Hours Maintenance Sewage Pump and Annually 45 Pumps 8 Manhours 360 Hours Motor Maintenance Check Inspection Twice per Week 106 Manholes 10 Minutes 1837 Hours Manholes Root Cutting Semiannually 19200 LF 1500 LF/30 Mhours 768 Hours Grease Removal Annually 5200 LF 1500 LF/30 Mhours 104 Hours Line Flushing Once per Month 1 Set 14 Manhours 168 Hours TOTAL PREVENTIVE MAINTENANCE 3589 Hours TABLE VII-4: STAFFING TIME FOR OPERATION TASKS TASK TIME PER TIME REQUIRED ACTIVITY FREQUENCY ACTIVITY PER YEAR Lift Station Inspection Daily 7 Mhours/Day 2555 Hours Video Inspection Once per Week 30 Mhours/Week 1560 Hours Work Logs Daily 10 Mhours/Day 2600 Hours Vehicle Inspection Daily 0.5 Mhours/Vehicle 650 Hours Staff Meetings Daily 0.5 Mhours/Day 910 Hours Tool and Once per Week 5 Mhours/Week 260 Hours Equipment Cleaning TOTAL FOR OPERATIONS 8535 Hours Source: Gary Morrison 7-9 CHAPTER SEVEN If due consideration is given to the hours involved in vacation, holiday, illness, meetings, training, on-the-job travel and startup time, then the total number of hours actually available for performing the work of operation and maintenance diminishes to a level of approximately 1,662 hours per year per crew member. At this rate, a staff of eight full-time maintenance crew members is necessary to accomplish preventive maintenance and normal operations activities and respond to emergencies. This analysis indicates that the Wastewater Utility Operation and Maintenance Department is not adequately staffed to regularly perform the basic tasks required to provide minimum recommended maintenance to the system. An expansion of the system requiring new service connections and/or additional facilities, without enlargement of the staff, will result in increased neglect of necessary maintenance. In view of predicted population growth in the service area over the next several years and the growing demand for sanitary sewer service, the need for additional staffing will continue. Many arguments support the wisdom of adequate staffing in any work place. The most persuasive argument relevant to a complex sanitary sewer system is that short staffing causes preventive maintenance schedules to be neglected. When routine,regular preventive maintenance tasks are dropped, breakdowns result, increasing both breakdown maintenance and excessive reliance on expensive standby equipment required to resolve emergencies. Regular performance of all necessary work in the Wastewater Utility Operation and Maintenance Division, with the current number of service connections, will require additions to the present maintenance crew. The expected increase in the number of service connections should serve as further impetus to develop a staff of an adequate size to effectively operate and maintain the system. The size of the maintenance crew should be increased from six to eight personnel while retaining the supervisor. This addition to the staff will create the adequate number of crew hours necessary to carry the full work load of the Utility without neglecting preventive maintenance, emergency preparedness, or safety precautions. Maintenance and technical staff additions should be accompanied by additions to the clerical, secretarial and other support staff needed to ensure that record keeping, billing, public relations, communications and other general functions of support staff are performed with the accuracy and timeliness required. 2. WASTEWATER UTILITY ENGINEERING STAFF The current engineering staff organization is illustrated in TABLE VII-1. There are currently four employees involved in utility engineering tasks; however, the Wastewater Utility section supervisor works part-time in the Stormwater Utility. The engineering staff is responsible for two major tasks, administrative and capital improvement projects. 7-10 Ii Operations and Maintenance The various administrative tasks and the hours of work required are shown in TABLE VII-5. The number of hours required for each task is not easily defined; therefore,work loads have been estimated based on a full-time employee (1.T.E). Administrative tasks alone requires approximately 2.0 FTE's. Therefore, it is evident that the administrative activities require a major portion of the engineering staff resources. TABLE VII-5 also shows the capital improvement projects which are currently under way within the City. These five projects require approximately 0.8 1-- h's. The total time required to perform all the tasks that the. City is currently performing is approximately 2.8 FTE's, which corresponds very closely to their current staffing level of 2.6 r 1h's. Most of the capital improvement projects identified in the 1983 Comprehensive Sewer Plan were not completed. The primary reason for the City's inability to carry out a capital improvement program is not a lack of available funding, but a past and current lack of engineering staff to design or manage the projects. The level of staffing within the City's Wastewater Utility section may be the biggest obstacle to the implementation of this plan. The proposed capital improvements require that approximately 14 to 16 projects are under way at any one time. Current staffing levels can only accommodate approximately four capital improvement projects. In order to implement this plan, additional staffing of approximately 2.5 FTE's will be required in order to accommodate 14 to 16 capital improvement projects per year, beginning in 1991. 'Additional administrative tasks which are recommended in this plan are (1) prepare new ordinances and revise existing ordinances, (2) setup and administer grease trap management and certification ordinance, (3) inventory and update hydraulic computer model, and (4) perform computer analyses using the sewer system hydraulic model. These tasks will require additional staffing of approximately 0.5 Frt.'s. This will bring the total,additional staffing, requirements for both administrative tasks and capital improvement projects up to 3.0 FTE's, bringing the total wastewater staffing level up to 5.5 FTE's. These additionswill likely result in the section supervisor increasing supervision duties and eliminating project managements duties. 7-11 CHAPTER SEVEN TABLE VII-5: WASTE WATER UTILITY ENGINEERING STAFF TIME NUMBER OF ENGINEERING TASKS EMPLOYEES Section Supervison 0.20 FTE's Latecomer's Agreement Administration 0.20 FTE's Sewer Moritorium Administration 0.30 FTE's Plan Review Support 0.60 FTE's Comprehensive Sewer Plan Update 0.20 FTE's Customer Service Support 0.25 FTE's Support to Other Divisions/Departments/Agencies 0.25 FTE's TOTAL ADMINISTRATIVE TIME 2.00 FTE's Major Capital Improvement Projects East Renton Interceptor 0.20 FTE's Minor Capital Improvement Progects West Kennydale Interceptor 0.20 FTE's Interim Sewer Improvements 0.10 FTE's Lake Washington Sewer Improvements 0.10 FTE's Park Avenue Interceptor 0.10 FTE's Infiltration and Inflow Program 0.10 FTE's TOTAL CEP TIME 0.80 FTE's TOTAL ENGINEERING TIME 2.80 FTE's FTE's=Full Time Employees Source: Randall Parsons,Stormwater and Wastewater Utility Supervisor 7-12 CHAPTER VIII FINANCIAL IMPACTS CHAPTER VIII FINANCIAL ANALYSIS A. INTRODUCTION This chapter considers the financial impacts that the Capital Improvement Plan (CIP), recommended in Chapters 5 and 6, will have on the wastewater utility's budgeting process. The proposed wastewater utility CIP consists of the rehabilitation, replacement and new construction of sewer facilities that are necessary to meet the policy goals stated in Chapter 3, the design standards and criteria presented in Chapter 4 and the service needs that will result from anticipated growth. This chapter also presents a financial analysis of the wastewater utility which identifies its historical and projected future expenses and compares them to available and projected revenues in order to determine the necessary rate adjustments. A utility rate study that evaluated the operation of the 401 and 421 funds and made specific rate recommendations was completed in November 1989 (Water and Wastewater Rates Managements Analysis, RH2 Engineering P.S.). This rates management analysis was intended to guide rates management for a period of two years while a reorganization of the Public Works Department was taking place. During the first quarter of 1992, the financial models developed in the rates management analysis should be updated so that recommended rates can be adjusted to accurately reflect the current financial situation within the utility. The utility's financial situation has also changed because of new state laws regarding how fees and charges must be calculated (Substitute House Bill 2929), and because the City is taking steps to adjust all of its rates, fees, and charges to meet its projected costs. In this chapter two sets of numbers are used. Current 1990 dollarsare used to project the costs of operations, maintenance, and capital improvement programs. However, several factors may affect the accuracy of those projections. The most significant factor is inflation. Although we cannot predict the exact amount inflation will increase costs, we estimate it will be 5% a year. Other factors that may affect future costs that we have not included in our cost estimate are contractor availability, technological advances, and changes in laws and policies. B. WASTEWATER UTILITY EXPENSES AND REVENUE REQUIREMENTS There are four major expenses of the wastewater utility, which fall under two broad categories-- - operating expenses and actual construction costs for CIP projects. Operating expenses include costs for operations and maintenance and METRO charges. Actual construction costs include the expenses for implementing the CIP and debt service costs. Inflation, defined as a general rise in prices, affects each of these expenses to a different degree. A summary of the major expenses 8-1 CHAPTER EIGHT of the Wastewater Utility is shown on FIGURE 9. A detailed description of each expense is presented below. To determine the revenues needed to meet each expense, one must forecast future levels of 1) inflation, 2) customer service increases, 3) METRO rate increases, 4) increases in operations and maintenance costs, 5) the City's share of costs for financing the CIP, and 6) anticipated revenues from other sources to finance the remaining portions of the CIP. C. OPERATING COSTS AND REVENUES All operating costs fall into two general categories: 1) The city's operations and maintenance expenses (controlled by City's budget process) and 2) the METRO sewage treatment charges (no direct control by the city). A summary of these costs is shown on FIGURES 9 and 10. It is evident from FIGURE 10 that the majority of the operating costs are a direct result of METRO changes. The Wastewater Utility rate increase necessary to cover the operating costs is presented in TABLE VIII-1. 1. Municipality of Metropolitan Seattle (METRO) Charges METRO charges for wastewater treatment and disposal. As part of its service contract with METRO, the City collects that charge from its customers through the utility billing division and passes it on to METRO. METRO has increased its rates substantially and will continue to do so to meet new treatment requirements. METRO treatment services are forecast to increase at an average annual rate of 13%. 2. City of Renton Operations and Maintenance a. Costs The estimated costs to operate the wastewater utility include salary costs for the operation, maintenance, engineering and administration of services, taxes, office supplies, debt service, and consulting fees. For eighteen months the wastewater utility has been in transition because of the Public Works Department's reorganization which separated the wastewater utility from the water utility. As part of the reorganization, the number of staff and additional staff positions for each utility were identified. For purposes of this financial analysis,recommended staffing levels for operating the wastewater utility were predicted to be reached within a five-year period in order to keep pace with anticipated growth. Inflation for labor is estimated to be 5% annually, with an additional 5% step increase applicable to 50% of the work force. Other expenses are anticipated to increase at the estimated inflation rate of 5%. 8-2 Financial Analysis CITY'S REVENUE BREAKDOWN SUMMARY FIGURE 9 Revenue projection requirements based on proposed capital improvements and operation and maintenance. j • $3 • AMEIMPEn. :::::::„ 2=118 •••••• M :I 2.06M ::: 1.85M $2 1.58M UNDMiN ::•••••• 1.20M 1.13M I! $1 0.9 • 0 98M a98M 0.99M 1.00M ' 1.02M 6M .4•..§. • • , .„., 7 ' , • 1990 1991 1992 1993 1994 1995 YEAR mil City Operations EJ City Proposed CIP • • 8-3 CHAPTER EIGHT TOTAL REVENUE REQUIREMENT SUMMARY FIGURE 10 Sto-/ Revenue requirements based on proposed capital improvements,operation and maintenance, '":.:: and METRO revenue forecast. : 2.06M :6 .85 1 M S6-✓ . • 1.02M` 158M 1.00M / }t.hc.

NOTE: NOTE: Project cost estimates Breit'1990 dollars CHAPTER EIGHT b. Revenue Requirements For purposes of the financial analysis, the estimated revenue requirements for the next five years (1991 to 1995) were based on the 1990 operating budget--which reflects the new organization with additions for planned new services and inflation. Customer servicegrowth was assumed to occur at 2% per year, which increases'revenues from rate collection by 2%. The capital budgets were based on the five-year CIP recommended in this Plan. In addition to reflecting the new organization, the 1990 operating budget was used as a base rather than actual historical expenditures, because the old organization's cost allocations were imprecise and based on a time-reporting system which was unreliable. The transition's effect, however, has not been completely reflected in the currently available financial information and will not be completely reflected until the City obtains the first nine months of 401 and 421 fund operations of 1991. D. CIP COSTS AND REVENUES 1. Capital Improvement Plan Costs The recommended CIP presented in this Plan consists of improvements necessary to serve the projected service area's population at saturation at the lowest reasonable cost. Consequently, the CIP's recommendations are based on saturation conditions and will be implemented as they are needed. The project costs listed here are intended for budgetary purposes.only, because. they are based on current construction costs and should be adjusted for actual inflation depending upon the actual construction date. The cost for the _ recommended CIP in the City's budget process is shown in the annual budget in the 421 account. The costs for all of the improvements have been estimated, based on current information available. It should be reiterated that changes in system flow rates, system growth, financial policies, and regulatory requirements all contribute to adjustments in long-range planning. We recommend that financial goals be evaluated every five years, and that a detailed cash flow analysis be conducted annually. TABLES VIII - 2, 3A & 3B present the estimated costs of the capital improvement program as recommended in this Comprehensive Plan. TABLE VIII-2 summarizes these annual costs of the CIP program showing the total project cost (current and inflated dollars) and the City's share of the program costs (current and inflated). TABLE VIII-2 also presents the City's share as estimated in the Rates Management Analysis accomplished during 1989. FIGURE 11 graphically presents the information provided 8-8 Financial Analysis in TABLE VIII-2. TABLES VIII-3A & 3B show an annual breakdown for each capital improvement project using current dollars. These estimates of funding responsibilities are based on the financial policies presented in Chapter 3. Debt service is a major cost of operating a wastewater utility. The majority of funding for the CIP has historically been provided through revenue bond sales, which means the utility borrows money from inventors while agreeing to repay those investors part of their debt with interest each year. This debt service (principal and interest) is funded from the 401 account (Utility Operations and Maintenance) because the debt service is a high priority lien on the revenues of the utility. Specific restrictions are contained in the bond covenants which restrict financial procedures of the utility. For example, the wastewater utility is required to set rates that must exceed its costs for operating and maintaining the • system, cover payment of the debt service and cover an additional specified percentage of debt service. 2. Revenue Sources for CIP • a. City Share In the financial analysis, the new debt service was calculated as the amount necessary to fund the City's share of inflated CIP costs. The analysis also indicates how this additional debt service affects the operating costs identified in the Rates Management Analysis (RMA). That adjustment to the RMA will determine the rate adjustments necessary to accomplish the CIP. Those costs will be recovered from customers based on their specific degree of benefit. The City's share of funding originates from three different sources; Revenue Bonds, General Obligation Bonds and the Public Works Trust Fund. These funding sources are discussed in detail below. 1) Revenue Bonds Revenue bonds are issued and sold by the City when large amounts of money are needed to build general purpose capital improvements that benefit the City as a whole. The City, like other municipalities, is capable of issuing tax-exempt bonds. The principal and interest payments for such bonds are repaid from general revenues, connection charges, assessments and interest earned on investments. In order to qualify to sell revenue bonds, the City must show that its net operating income (gross income less expenses) is equal to or greater than 1.3 times the annual principal and 8-9 , CHAPTER EIGHT interest due for all outstanding bonded indebtedness. The 1.3 factor is commonly referred to as the "coverage factor." 2) General Obligation Bonds The City has the authority to levy a tax (subject to a vote of the people) that could be used to pay principal and interest costs of a general obligation bond issue. The City has not used this means of revenue generation for the wastewater utility and does not plan to unless a serious disaster•occurs that requires massive improvements and/or replacements beyond the City's ability to fund it through other sources. 3) Public Works Trust Fund Loans Low-interest rate loans are available from the state for replacement of existing sewer system facilities. Interest rates vary from a low of 1% to a high of 3% depending upon the City's matching share. It is emphasized that these low interest rate loans are for replacements only and can not be used for accommodating growth. These loans can be utilized effectively for replacements in the Central Business District (CBD) and other fully developed areas of the City. b. Other Revenue Sources For CIP This section presents the anticipated funding for the CIP from sources other than rates revenue. Five funding sources are identified and these are discussed in more detail below. 1) Grants Federal and state loan and grant programs are available for wastewater capital improvement projects. These programs are primarily designed to fund improvements that upgrade wastewater treatment facilities in order to comply with Federal Clean Water Act (PL92-500). With budget cutbacks at both the federal and state level, the possibility of receiving government funding for a portion of the recommended improvements at this time is remote. Should additional funds be made available, the City should explore the feasibility of obtaining funds from these sources. 8-10 Financial Analysis The Centennial Clean Water Fund is an example of state grant funding which is currently available. This grant fund's highest priority is to eliminate public health emergencies and secondly, to improve water quality. The City should continue to pursue these funds. 2) Municipality of Metropolitan Seattle (METRO) METRO funds are available for the construction of interceptors and local service extensions if the investment can be justified. Currently METRO limits its investment to projects where the amortized capital cost of the project can be recovered through METRO fees collected from the residential customer, or equivalent, that are served by the extension at the time of project completion. Based on this policy, METRO could construct the May Valley Interceptor and other improvements. 3) LID (Local Improvement District) Assessments LID assessment income is paid to the City from assessments levied against specific properties which have benefitted from improvements in a defined area. Typically, Local Improvements District's (LIDs) are formed by the City at the written request (by petition) of property owners within a specific area of the City. Upon receipt of a sufficient number of signatures on petitions, a local improvements area is defined and improvements are designed for it. Each separate property in the LID is assessed in accordance with the special benefits the property receives from the sewer system improvements. Generally, it is the policy of the City to assess the benefitted properties 100 percent of the cost of the improvements plus the general facilities and sewer connection charges. LID projects may be divided into two categories. a) Improvements of Local Interest If necessary, specific problems, such as excessive septic tank failures, can be corrected through an LID. If not necessary, these projects can be postponed until a later date when the area needs or desires it. 8-11 1 CHAPTER EIGHT b) Improvements of Regional Interest These project are beneficial to an area larger than an LID and are initiated by the City. While LID funding would help, the project is of such importance that a lack of LID should not delay it. If an LID cannot be formed, additional funding from other sources (including the City) may be necessary. 4) Developers City policy requires that all developers/property owners take financial responsibility for the necessary improvements before their development benefits from them. This responsibility may be satisfied in one of the following ways. In all cases, developer/property owners should be required to pay for the costs to the extent their property benefits from the facility installed (their fair share). a. If the utilities necessary are already installed, the developer/property owner will reimburse the party (city or private) that installed the facility through a latecomer agreement or special assessment district. b. If the utilities necessary are not installed, then the developer/property owner must extend or make improvements to the facilities following routes that comply with the City's Comprehensive Sewer Plan. If the plan is not definitive for that area, then the facilities will be extended and installed in a manner that best serves the City of Renton's citizens as determined by the utility system manager. If the facilities installed potentially benefit other properties, a latecomer's agreement may be requested. If the facility required by the City is determined by City Council to be significantly more expensive because of oversizing or routing requirements, then the Council may agree that the City participate. If a City capital .improvement project is being planned, designed or constructed, developer/property owners could choose to participate financially in the City's project rather than make the improvements themselves. 5) Other 8-12 Financial Analysis This category of funding responsibility is primarily for participation by other municipalities, such as adjacent cities or districts. Negotiations need to be accomplished to finalize funding responsibilities before annual adjustments to the CIP and rate increases. c. Contingency Revenue Plan If the funding from other sources does not happen as anticipated, or on the schedule anticipated, then the City should adjust this plan's CIP. Alternative adjustments available to the City are as follows: Reduce the scope and magnitude of the improvements with corresponding reductions in cost, Defer that portion of the improvements necessary for the benefit of others until the funding is obtained, Proceed with the CIP as recommended in this plan and finance the other beneficiary's share with the provision that these other costs should be recovered including interest costs. It is critical to implementation of the CIP that these funds be obtained from other funding sources. The level of funding from other sources is based on the current perceived degree of benefit from each project; this may change based on the actual degree of benefit assessed at the time the project is planned to begin. E. FINANCIAL ANALYSIS The City has control of only approximately 40% of the total wastewater utility budget; METRO charges are responsible for approximately 60% of the total budget. The City's major source of revenue is from sewer collection charges from its customers. Theses charges provide the necessary revenue for the operation and maintenance of existing sewer facilities and for the City's share of the CIP. The financial analysis, summarized in TABLE VIII-1 (page 8-4), illustrates that the City must raise its sewer collection charges by 64.4% over the next four years. This is equivalent to an average annual rate increase of approximately 13.2% per year. However, the same financial analysis also illustrates that these rate increases are not uniform but require a greater percentage increase in 1992 (18.1%) then taper off to a smaller percentage increase in 1995 (8.8%). The rate increases depend on several factors which can change. These factors are summarized below: 8-13 CHAPTER EIGHT 1. The customer base for the City is forecast to grow at an annual rate of 2% over the next five years. If this growth rate is greater than 2%, adjustments to sewer collection rates may be less than projected; however, if the customer base increases at less than 2% per year, then adjustment to these sewer collection rates will lead to an increase above what is shown in TABLE VIII-1. 2. A significant portion of the wastewater utility's budget cover operations and maintenance personnel costs. If recommended additions to the staff do not occur, then the rate increases shown in TABLE VIII-1 could be reduced. The cost savings would be offset, however, by the consequences of having inadequate and unqualified personnel; the wastewater utility would not function efficiently and would not provide adequate services to its customers. 3. The financial analysis assumes the CIP in this Plan will be implemented. If it is • not, whether deliberately or unintentionally, then the required rate increases presented in this financial analysis will change. It should be noted that delaying the implementation of this CIP may initially result in lower rate increases; however, if facilities fail,then unplanned and costly repairs will be needed, which often results in excessively high rate increases in the future. Currently, the City Council and wastewater utility are implementing financial reviews through the annual budget process. These reviews allow the wastewater utility access to the latest and most accurate financial date, allowing more informed decisions. The wastewater utility will continue to work with the City Council to recommend the necessary rate increase needed to maintain and improve the system in order to provide the residents of the City with effective, safe, and reliable sewage disposal service. 8-14 APPENDIX A SEWAGE LIFT STATION DATA SHEET laA I..

Under date of August 11th, 1970, the City and Safecare- Careage entered into the Safecare-Careage Contract which permitted Safecare-Careage to build the Springbrook Line hereinabove _,_ defined. (2.) Said contract provided for reimbursement to Safecare- Careage, subject to the laws and ordinances of the City of Renton, by the owner of real estate who did not contribute to the orig- inal cost of the improvement and who subsequently wished to tap into or hook onto or use the facilities. (3.) Said contract also reserves to the City the right to make or cause to be made extensions of or additions to the above-mentioned improvement and to allow service connections to be made Co said extensions or additions without liability on the part of the City. (4.) The properties, the owners of which are to be charged for tapping into or hooking onto the Springbrook Line, and the amount and rate of said charges for said properties, have already been determined in accordance with Ordinance No. 2847 of the City of Renton.- Of the properties involved in this Agreement, they are the properties, sewer service to which is to be provided by the City and not by the District under this Agreement. (5.) The City is presently providing sewer service to Lots I and 2 of Scott's Terrace by means of the existing crossing. (6.) No formal agreement for the provision of sewer service in the subject area has been entered into between the City and the District. (7.) The City also proposes to provide sewer service to Lots 4 and 5 of Scott's Terrace by permitting the construction of the proposed crossing. (8.) The City is prepared to furnish sewer service through the Springbrook Line to Lots 3, 6, 7 and 8 of Scott's Terrace. (9.) Although all of Scott's Terrace and the Radovich Property are within the Cascade Sewer District and are outside the limits of the City, each party recognizes that sewer service to Lots 1, 2, 3, 4, 5, 6, 7, 8 and 16 of Scott's Terrace and to that portion -3- of the Radovichert ro which P P Y lies to the west of the southerly prolongation of the westerly boundary of Lots 17 and 18 of Scott's Terrace can be provided by the City through the Talbot Road Line sooner than such service could be pro- vided by the District, and that sewer service to these prop- erties by the City and the payment to the City of the charges necessary under the Safecare-Careage Contract as already de- termined pursuant to said Ordinance No. 2847 has and will pro- vide the funds for reimbursement of Safecare-Careage under the contract. • (10.) The District proposes to serve the properties within U.L. I.D. 11 by utilizing the existing crossing and the proposed crossing as hereinabove defined. (11.) Both the City and the District have identical agree- ments with METRO relating to the METRO Line, permitting both the City and the District to make sewer service available to • propefties along said line by allowing said properties to be hooked onto the METRO Line, making an appropriate charge to the owners of said properties and remitting the same to METRO as payment against the cost of the construction of said line. (12.) Because of the possible duplication of charges, and the question of the proper agency to•provide sewer service to various properties referred to above, the parties hereto do desire by this Agreement to formalize their mutual responsibil- ities and rights in the area. III. MUTUAL COVENANTS AND AGREEMENTS In consideration of the covenants herein contained, and in consideration of the benefits to each of the parties to be derived from this Agreement and the performance thereof, and -4- • , because of the facts stated above, the parties hereto do agree and covenant as follows: (1.) The City will make sewer service available for that portion of the Radovich Property lying west of the southerly prolongation of the westerly boundary of Lots 17 and 18 of Scott's Terrace and for Lots 1, 2, 3, 4, 5, 6, 7, 8 and 16 of Scott's Terrace, and the District will not attempt to provide sewer service for said areas. i . (2.) The City will authorize an extension of or addition to the Springbrook Line by permitting the construction of the �I. proposed crossing hereinabove defined. Said crossing must be in accordance with the standards and requirements of the City as to design and construction. The cost of the construction r» of said proposed crossing will be borne by the District or by private owners with whom the District may contract, or both, but the proposed crossing will be constructed at no cost to the City. (3.) When the proposed crossing is completed, it will be transferred to thejCity and will be available for the use of the City to provide sewer service to those lots in Scott's Terrace for which the City is to make sewer service available under this Agreement. (4.) Other than the properties described in Paragraph (1.) of Section III of this Agreement, the District will make sewer service available for all other properties within its boundaries in the area of U.L.I.D. 11. (5.) The City agrees that the District may, without pay- ment of any area connection charges, connection fees, latecomer fees, extended service fees, or any fee of any kind, but at the District's own cost of construction, connect its mains to the existing crossing to the proposed crossing when constructed, provided that the design and construction of the District 's -5- facility so connected meet with the approval of the City. (6•) Without any cost to the City, the District will place a manhole at the easterly end of the existing crossing and will connect the existing side-sewer to this manhole. The District will also cause a manhole to be constructed at the easterly end of the proposed crossing, and each of said manholes, when completed, will be transferred to the City to own as part of their main extensions consisting of the existing cros- sing and the .proposed crossing. Said manholes will meet the design and construction requirements of the City. (7.) Unless it has the prior consent of the City, the District will not attempt to make sewer service available to those properties lying immediately south of So. 180th Street and in the immediate vicinity of the Sringbrook Line which, without the construction of main extensions which would be exempt from any charges under Paragraph S of the Safecare- Careage Contract, can be served by that portion of the Spring- brook Line as presently constructed. (8.) Although portions of the lines hereinabove described will be jointly used by the City and the District, each of the parties hereto will maintain its own lines at its own cost. (9.) If all of the properties which are to be served by the District under this Agreement are annexed to and become a part of the City, the District will, without charge to the City, transfer to the City the entire sewer system to be con- structed by the District in U.L.I.D. 11 as described in this Agreement. (10.) All facilities constructed by the District which are to be transferred to the City under this Agreement will be transferred by an appropriate Bill of Sale in standard form. (11.) The District will hold the City harmless from any -6- • claims made against the City and will protect the City from any liabilities i;' connection with any of the work to be done by the District. (12.) Nothing in this Agreement as to which party shall pro- vide sewer service to particular properties shall be construed as to require the provision of such service except in accord- ance with the Ordinances or Resolutions of the party, and upon payment to the party of all proper charges by the property owner.

Rehab Existing Storm Sewer • TABLE 2 CONSIDERATIONS ON SELECTION OF PIPE MATERIALS The following considerations are to be used in conjunction with Table 1 for tentative selection of pipe materials. a. Rubber gaskets maybe severely damaged by petroleum products, particularly: in prolonged exposures to concentrated flows containing little or no storm water or sanitary sewage. b. Gasketed joints are not considered leak-proof at zero or low pressures, and may not be leak-proof at higher pressures. c. Mechanical joints may be less likely to leak at low pressures than push-on joints. d. May need protective coatings and/or cathodic protection against external -corrosion. e. Considered most reliable gasket and lining material for ductile iron leachate pipeline. f. Very difficult to repair linings on inside of joints in pipe smaller than 24-inch diameter. g. Almost always needs protective coatings and cathodic protection against external corrosion. h. Properly made joints are considered leak-proof. i. Polyethylene, although corrosion resistant, can be severely affected by prolonged exposures to petroleum products. j . Viton (or nitrile) gaskets may require long delivery time. k. Concrete pipe not recommended without "liquid-tight" lining of another material. 1. Potential to develop leaks at joints due to structural or gasket failures. m. Limited to low pressure applications. n. Pipe not available over 15-inch diameter. o. Requires special attention to bedding and backfill depth to avoid structural failure of pipe. p. Large thermal expansion coefficient. May need to limit solvent welded joints to 4-inch and smaller pipe. May require careful evaluation of pipe installation temperature and temperature of piped liquids to ensure joint integrity. _ q. Pipe not available over 12-inch diameter. r. Insituform lining is available in 6-inch through 60-inch diameter for almost any pressure, if sufficient pipe cross-sectional area is available s-u. Not used. v. Suitability of pipe lining and gasket material to resist chemical attack by conveyed fluids must be determined for each pipeline service considered. w. All storm and sanitary sewer manholes, catch basins, and inlets should be equipped with precast concrete bottom and sidewalls with rubber gasketed joints between sections, water-tight epoxy grout pipe entrances through walls, and bitumastic coating of all interior floor and wall surfaces. Manholes, catch basins, and inlets should have no leakage when hydrostatically tested at atmospheric pressure! x. Has good resistance to chemicals, petroleum products, and hydrogen sulfide corrosion. y. Not recommended for buried applications due to limited experience and high cost. z. "Zero leakage" test requirement may be impossible to achieve under the best conditions for any pipe material because trapped air ray distort test results, even in a drop-tight pipe. Pressure and leakage test requirements should consider whether the pipe has steep slope or will stand full of liquid. Pipelines should be tested with the intent to prevent or minimize leakage. Air testing should not be allowed; hydrostatic testing should be as stringent as any found in the industry. Pipe materials, without regard for chemical attack, corrosion, or puncture, are generally ranked as follows, in decreasing order of liquid-tight reliability: welded steel with welded joints high density polyethylene with thermal-fusion joints PVC with solvent welded joints fiberglass with welded joints Insituform liner ductile iron with viton or rubber gaskets concrete cylinder with gasketed joints welded steel with rubber gasketed joints PVC with viton or rubber gasketed joints concrete pipe with rubber gasketed joints 8-701 8-702 "Side Sewer" shall mean that portion of the public sewer between • primary collection lines and individual!property lines.

If no timely payment is made as herein set forth and the account thus becomes delinquent, the Director of Finance, or her duly authorized representative shall mail to the user a notice in writing, postage prepaid and mailed to the last known address of such user, that if such delinquent sewer charges are not paid forthwith, the Utilities Engineer shall be directed to cut off the water service to the premises and to enforce the lien upon the property to which such service has been rendered and such lien shall 589 8-716 8-716 be superior to all other liens or encumbrances except those for general taxes and special assessments. Such liens may be foreclosed by the City in the manner provided by law for the enforcement of the same, and for delinquent sewer charges, in addition • to all other remedies permitted. There will be an:additional sum of ten dollars ($10.00) charged for the expense of turning the water off and on. Any such water service cut off shall remain disconnected until all charges to the City plus penalties, together with the additional sum of ten dollars ($10.00) for turning the water on, shall have been paid. In lieu of any notice by mail, the Utilities Engineer or the Director of Finance, or their duly authorized representatives, may cause a delinquent sewer charge notice to be - served personally upon such user or occupant. Failure to receive mail properly addressed to such user or occupant shall not be a valid defense for failure to pay any such delinquent charges. Any change in ownership of property or change In mailing address must be properly filed in writing with the office of the Director of Finance within fifteen (15) days after such change of status. (Ord. 2847, 5-6-74) (See following page for Section 8-717) 589 8 8-717 —717 8-717: CHARGES FOR PROPERTY NOT PREVIOUSLY ASSESSED: (A) The special connection charge imposed shall be paid into the Waterworks Utility Construction Fund. The charge shall be paid in cash whenever such connection is requested, or application may be made by such property owner toprovide for the payment thereof by, an installment contract if the amount is in excess of five hundred dollars ($500.00), with interest at the rate of ten percent (10%) per annum, computed 'annually on unpaid balances, which contract shall provide for a minimum down payment of not less than ten percent (10%) of such total connection charges hereinabove set forth, payable upon execution of such contract and the balance thereof to be paid in not more than twenty (20) quarterly installments payable on each January 1, April 1, July 1, and October 1. Such installment contracts shall provide that any unpaid balance may be paid in full in any year at the time the first quarterly payment of such year is due and payable, shall describe the property served by the water, and shall be duly acknowledged by the property owner and be recorded by the Public Works Director in. the office of the County Auditor at the expense of such property owner. Delinquent payments under such installment contracts shall be a lien upon the described property as provided for in RCW 35.67.200, and enforceable in accordance with RCW 35.67.220 through 35.67.280. As an additional and concurrent method of enforcing such lien, the water service to such property may be disconnected in accordance with RCW 35.67.290 and this Code until such time as all-delinquent payments have been paid in full. Upon full payment of such installment contract, the Public Works Director, on behalf of the City of Renton, shall execute and deliver unto the property owner a release of such lien, which shall be recorded, at the expense of the property owner, with the King County Auditor's office. All installment payments so made shall be applied first to interest accrued up to date, and the balance to principal. (B) In addition to sewer connection permit fees as required by ordinance and the rules and regulations promulgated thereunder, there is hereby imposed upon, and the owners of properties which have not previously been assessed or charged or borne an equitable share of the, cost of the City's sewer distribution system shall pay, prior to any connection to a City sewer main, one or more of four (4) special connection charges, herein defined, in an amount to be computed under the following paragraphs of this Section. 1. Latecomer Fees. The imposition, collection, payment, and other specifics concerning this charge are dealt with elsewhere in this Code. 2. Special Assessment Charge. The special assessment charge is a charge for the historical costs for the sewer collection system, which system shall include the sewer collection mains that lie adjacent to or near properties that would behefit directly therefrom, that were not installed by L.I.D.'s or by a private developer under a latecomer agreement. 589 8-717 8-717 B,2) (a) The number of units of property frontage to be served by the sewer distribution system, determined in the manner prescribed in RCW 35.44.030.040 and .047 for determining "assessable units of frontage", shall be multiplied by the actual local improvement assessment per unit of frontage for such facility for the year in which the sewer main to which the property is to be connected was constructed and accepted as complete by the City. (b) In addition to the aforestated cost of "assessment" there shall be a charge of ten percent (10%) per .annum added to such cost, but in no case shall such charge be in excess of one hundred fifty percent (150%) of the original assessment cost. Interest charges should be simple interest and not compound interest. (C) Such special connection charge for property abutting on a street in which a sewer can be constructed .or extended to serve such property but can be connected without actual construction or extension, shall be computed as if the sewer was-so constructed or extended; and the special connection charge for property:located.back from the margin of the street in which the sewer exists and outside the assessment district created therefor shall be made giving consideration to the distance of said property from the street margin. In no case shall credit be allowed for the cost of extra length of side sewer required for connection to the City's sewerage system; provided,. however, that in cases where application of the foregoing formula to a particular parcel of property results in a charge, which because of unusualconditions, or conditions peculiar to said property only, is in excess of charges to similar properties, the Public Works Director is authorized to reduce the special connection charge to such an amount charged to properties similarly situated. 3. Special Utility Connection Charge. The special utility connection charge which shall be assessed "against . any property which has not participated in the development of the sewer system, which system shall include lift stations, force mains, interceptors and other collection mains, shall be assessed at the rate of: (a) Three hundred dollars ($300.00) per single-family residence and mobile home dwelling; (b) One hundred seventy five dollars ($175.00) per living unit of an apartment, condominium, cooperative rental, time-share, motel, hotel, or similar multi-family occupancy residential structure; (c) For all other properties except City properties, four cents ($.04) per square foot of property connected but not less than three hundred dollars ($300.00); (d) Fees are incurred upon the granting by the City of a building permit, but are payable at the time construction inspection permits are issued for public sewer extension. All other sanitary sewer service applicants shall pay these fees at the time of building sewer application; • 589 i 8-717 8-717 B,3) (e) Fees are due immediately, notwithstanding the prior paragraph, if the party oWing. the fee sells to a third party, unless the third party agrees to pay the charge, in.writing, with the amount owing to the City.set forth in that writing, and further the City;agrees that the third party shall be responsible for that fee after determination that such an agreement would be in the City's best interest. The burden of establishing the agreement would be on the party owing the fee and not on the City, and would be in the City's best interest; (f) When the phrase "property which has not participated in development of the system is used l in this Section, it shall mean property which has not paid a special utility.connection charge for the property based upon the square footage of the property that is to be served by the utility. For example, one single-family residence On a five (5) acre tract which has paid three hundred dollars ($300.00) under this Section to connect to a sewer system will have paid only for one seven thousand five hundred (7,500) square foot lot at the rate of four cents ($.04). Additional charges would be applied for any additional development on the property. Property that was developed before the effective date of the first connection charge _ ordinance in 1965 is exempted from the connection charge. Any rebuilding or additions to-exempted property that does not require additional water usage such that a larger domestic meter is necessary will not trigger a hew connection charge. However, when property is redeveloped or the use changed or intensified such that a.larger domestic water meter or additional domestic water meters are necessary or when no domestic water meter was obtained before, such as property on a well, then any application for the initial water meter or a lager water meter will trigger a utility connection charge. For the purposes of this policy, such property when applying for an initial or larger water meter shall be property that has not been previously assessed. When property is redeveloped and the use intensified such that a four inch (4") (residential) sanitary sewer stub is required to be replaced with a six inch (6") (commercial) sanitary sewer stub, to the sewer main, then any application for the sewer construction permit will trigger a utility connection charge. (g) No special itility connection charge will be collected on City-owned properties. The benefits to the utility from the use of other City properties such as utility easements, lift stations, and other benefits offset the amount of the utility connection charge fee; (h) When calculating the area to be charged the connection charge, undeveloped greenbelt and major easements within the property shall not be included in the square footage for the calculation of the charge. When determining whether property is undeveloped greenbelts or major easements, the inquiry should be to recorded easements or dedications or restrictions on the comprehensive ,plan or zoning maps or City policies that would prevent development or significant usages. This exemption is intended not to charge property that is undevelopable; •589 8-717 8-720 B,3) (i) There shall be no other exemptions from the special utility connection charge. Any party extending utilities that may serve other than the party's property may request a latecomer's agreement from the City. Any party required to oversize utilities may request that the utility participate in the cost of the project. 4. Inspection and Approval. Fees. In addition to other permits and fees, there will be an inspection/approval fee for on-site and off-site replacement and improvements which shall be identical to that specified in Chapter 8, Title IX and any subsequent amendments thereto. . (C) If any such property for which a special connection charge has been paid later becomes subsequently included 'in a local improvement district for the construction of a sewer of the same or similar nature, then the principal amount so paid shall be credited to theassessment against such property and such amount shall be paid from the Waterworks Utilities Fund into such Local Improvement District Fund.

Some materials are better suited than oithers; however, there is no clearcut best choice of pipeline material for a given service. For brevity, the list of suggested material specs does not include the many specifications which cover details such as gaskets,' Coatings, etc. It is our understanding ,that the City will incorporate this list by reference into the Aquifer Protection Ordinance to provide guidance concerning allowable pipeline materials within Zone 1_ of the Aquifer Protection Area, for both new • construction and rehabilitation or replacement of existing pipelines.

Our letter of November 21, 1989 did not specifically address use of these materials. apse . Based on experience of others within CH2M HILL, we recommend that • pressure grouts and gels not be used for rehabilitation of storm or sanitary sewers within your aquifer protection area. In our opinion, all of these product applications have only a limited life expectancy, on the order of five years, and are not a long term solution to ensure the tight sewer leakage requirements . needed .in .the aquifer area. Further, these product applications, usually installed from inside the pipeline, are more applicable to correcting infiltration problems than to correcting exfiltration problems.

CHAPTER I SUMMARY AND INTRODUCTION A. PURPOSE OF PLAN The purpose of the Renton Comprehensive Sewer System Plan is to present policy and design criteria and to recommend facility improvements. This plan will be used as a guide in maintaining and improving the sanitary sewer system over the next five years in order to provide the residents of the City with an effective, safe and reliable sewer system. This plan is not an update to the Comprehensive Sewer Plan adopted in 1983; it is a complete re-evaluation of the entire sanitary sewer system. A summary of this plan's findings and recommendations are presented in this chapter. - The plan results from a study that evaluated the existing sanitary sewer system and developed recommendations to resolve existing deficiencies and concerns,and to accommodate growth. The improvements identified in this plan are based on the requirements of the Washington State Department of Health, Washington State Department of Ecology and City Policy. The City of Renton adopted its last Comprehensive Sewer Plan in 1983. That plan anticipated growth in the system and proposed improvements but did not foresee all of the issues that have arisen since that time: 1) concerns for groundwater protection, 2) significant increases in construction cost, and 3) increases in land use densities. These issues and others are examined indetail in this Comprehensive Sewer System Plan. The Renton sanitary sewer system is large, and because of the topography, it is difficult to comprehend. The condition of the-current system, as well as the need for improvements, has been documented in this report. Due to the complexity of this system and the number of issues that must be addressed, this repot is organized so that a reader may review a summary of it in this chapter without reading the.background or detailed information that led to those results. The plan provides a recognized framework for making decisions about sanitary sewer service in • the City of Renton. It is intended to aid decision makers as well as users, including the Wastewater Utility, City Council members, the Mayor and staff, builders,developers,community groups, and other government agencies. The plan will be a useful tool in the following ways: • • As a framework for improvements and operations that govern sanitary sewer system developments in the City's service area. The plan provides a basis for allocating improvements and costs to new sanitary sewer system users such as home and apartment builders, and commercial developers. It thus provides City officials with partial direction for approving building permits and upgrading the system. 1-1 CHAPTER ONE • To provide a guideline for improving the existing system so that each customer receives adequate sanitary sewer service. It is intended that City officials be able to use these guidelines to maintain a high quality of service at a reasonable cost. • To provide a basis for accommodating changes that occur but that cannot be forecast in the plan. To this end, the plan lists policy issues and operational criteria that can be used to develop alternatives and directions for development, improvements and operations. _ Several members of the City staff have a detailed understanding of the City's sanitary sewer system, and have provided valuable input for this plan. Mr. Richard Anderson, Mr. Randall Parsons,Mr. Mike Benoit,Mr. David Christensen, Mr. Gary Morrison and Mr. Jack Crumley are thanked for their assistance. B. AUTHORIZATION On November 7, 1988, the City of Renton authorized RH2 Engineering, P. S. to prepare the update to the Comprehensive Sewer System Plan in conformance with the Chapter 173-240 WAC. C.

EXISTING SEWER SYSTEM The City of Renton owns, operates, and maintains its sanitary sewer system. This system consists of approximately 153 miles of gravity sewer,.23 sewage lift stations and force mains, and approximately 3000 manholes. Wastewater is discharged to METRO facilities at 55 locations within the City from which it is conveyed to and treated by METRO's Renton Treatment Plant. The existing sanitary sewer system is shown on FIGURE 1. The City of Renton is divided into six major wastewater collection basins, each of which consist of one or more subbasins. For the most part, these collections basins and subbasins follow the natural drainage patterns of the Renton service area. These wastewater collections basins are shown on FIGURE 1. E. POLICIES AND DESIGN CRITERIA Policies, design criteria, and standards used for planning and operating the sanitary sewer system are based on laws and policies which originate from several sources. All these policies and standards have the general purpose of providing an acceptable level of service to the sanitary sewer customers. Policies presented in this plan include the following: customer service policies, • financial policies, facility policie , and organizational policies. Analysis and design criteria for the sanitary sewer system are based on standards presented in the "Criteria for Sewage Works Design" prepared by the Washington State Department of Ecology as well as standards set by the Municipality of Metropolitan Seattle (METRO) and City of Renton. F. LAND USE AND ADJACENT SYSTEMS 0 Land use proposed in the City's 1983 Comprehensive Land Use Plan was used to estimate wastewater flow rates at saturation conditions within the City. These saturation wastewater flow rates were used to analyze existing sewerage facilities and to plan for the location and sizing of new sewerage facilities. Existing land use designations are shown on FIGURE 6. There are several adjacent utility systems surrounding the City's existing service area,which limit the expansion of the City's sewer system. The greatest potential for expansion of the City's sanitary sewer system is within the May Creek and East Renton areas which currently either do not have existing or adequate sanitary sewer facilities. The adjacent utility entities are shown on FIGURE 7. 1-3 CHAPTER ONE G. KEY ISSUES This plan addresses the following key issues: • Excessive infiltration and inflow. • Extension of sanitary sewer service areas. • Aquifer protection and exfiltration from sanitary sewers. • Sewer system deficiencies including hydraulic constraints, substandard facilities, and replacement of old pipes. • Annexation and sewer service outside City limits. Several of these issues were also addressed during preparations of the 1983 Comprehensive Sewer Plan. H. SYSTEM ANALYSIS A hydraulic and a structural analysis were conducted to determine how well the existing system achieved current policies and technical, engineering standards. The plan identifies where the system failed to meet those objectives and recommends improvements to the existing system or construction of new facilities to achieve them. A hydraulic analysis is a computer simulation of the existing system to determine its ability to convey wastewater saturation flow rates. A computer model was developed and used to analyze the system and to size future facilities. This computer model will continue to be used by the City as an analytical, planning and management tool. A structural analysis, which is a visual inspection of the existing system, was also conducted and was based on video, as well as actual, physical inspections. The analysis revealed deficiencies that cover a broad range of areas. The hydraulic deficiencies identified are inadequate slopes (inability to achieve carrying velocities), insufficient capacity to handle wastewater flow rates,pipes that are less than 8-inches in diameter and sections that have reverse slopes. Structural deficiencies identified are pipe sag, and root and grease problems. The Renton sewer system has these hydraulic and structural problems in varying degrees throughout the system. I. SEPA A SEPA Checklist has been prepared for this plan and is presented in Appendix E. It is anticipated that this proposed plan will not have a probable significant adverse impact on the environment and that an environmental impact statement (EIS) will not be required. However, 1-4 Summary and Introduction many of the projects proposed herein will require SEPA checklists and some will require an environmental impact statement. J. CONCLUSIONS AND RECOMMENDATIONS In the development of this plan, the following conclusions were reached: 1. Two areas are seriously deficient in capacity: 1) The East Renton area (which includes South Highlands, Maplewood, and Heather Downs Subbasins) currently has a moratorium on connections until capacity improvements have been made, and 2) the Honey Creek Subbasin is at capacity and has some marginally reliable facilities. 2. A substantialY ercenta a of the system has reached the end of its useful life and P g needs to be replaced. These areas include the Downtown, North Renton and Highland areas. 3. The City needs to perform detailed testing to obtain better engineering information regarding the operation and hydraulic behavior of the system. Specifically, a detailed infiltration and inflow project should be performed as well as a video inspection to affirm this plan's evaluation and provide an improved basis for future.planning. 4. Design and construction standards need to be modified for use in aquifer protection areas. We recommend that a zero leakage policy be adopted for sewers within the Downtown and Maplewood aquifers. A specific example of an extremely high risk is METRO's Cedar River Interceptor sewer which currently traverses through the Downtown aquifer. We recommend that this sewer be relocated so that a failure or leakage is manageable, and contamination of the City's sole source aquifer is avoided. However, a zero leakage policy requires a special type of construction which would substantially increase costs over standard construction costs. 5. We recommend that the City adopt the following policy regarding extension 'of sewer service; where the City annexes an area that is currently unsewered by - another municipality, the City should provide sewer service; where annexation occurs and sewer service is provided by another municipality, the City should purchase the facilities from the adjacent municipality, based on that municipalities actual depreciated 'cost for providing the facilities to obtain service, so long as those facilities flow by gravity to the City system. ,I I 6. The rate increases recommended in this plan should be considered as the minimum level of increases necessary to implement the City-funded portion of the • recommended improvements. Currently, new development pays a major portion 1-5 CHAPTER ONE of the remaining cost of recommended improvements. If funding from this source, such as the special utility connecting fee, is not available, the City's share of these construction costs will most likely increase. 7. The City's sewer system is complicated; the preceding conclusions and recommendations are based onthe highest priority issues, which, in our opinion, must be confronted. However, we propose a substantial number of additional recommended facility improvements and modifications. When we assigned them priorities, we took into consideration the following characteristics: a. Whether a facility is structurally deteriorating or has hydraulic capacity problems. b. Whether an improvement increases overall efficiency by reducing operation and maintenance costs. - -- c. Whether an improvement helps protect the environment or reduces a threat to public health. K. SYSTEM IMPROVEMENTS The following is a summary of proposed improvements to the Renton sanitary sewer system, which are presented in this Comprehensive Sewer System Plan, to correct existing facility deficiencies and to accommodate growth. 1. Adopt this Comprehensive Sewer System Plan in order to establish consistent City policies and to provide the capability of efficiently planning the sanitary sewer facility improvements. This plan should be updated at intervals of no greater than five years in order to accommodate unforeseen changes in existing assumptions and conditions, and for adjusting budgets and sewer service rates. 2. Replace aging and substandard sanitary sewer facilities within the City. These sewers present a significant potential danger to the environment and public health. • 3. Continue development of the gravity sewer system in order to allow the elimination of existing sewage lift stations. These lift stations are less reliable, require higher maintenance and operation costs, and cause more adverse impacts to downstream facilities than do properly planned gravity sewer systems. 4. Rehabilitate or replace the sewage lift stations that are considered to be permanent sewage facilities. These improvements will reduce maintenance costs and increase system reliability. 1-6 Summary and Introduction 5. Examine program and projects that will reduce wastewater flow rates and infiltration and inflow within the sanitary sewer system. These may be cost- effective methods that could possibly reduce the size of sanitary sewer facilities, thereby reducing capital expenditures. 6. Implement sanitary sewer rate increases in order to finance capital improvement costs as well as operation and maintenance costs in accordance with the utility rates study. L. HOW TO USE THIS PLAN This plan is arranged in eight major sections: Chapter I provides a summary of the recommendations and conclusions presented in this Comprehensive Sewer System Plan.

A more extensive description and analysis of the system, along with recommended improvements, can be found in Chapter 5. A. OVERVIEW OF EXISTING SYSTEM The City of Renton is approximately 16 square miles with a population of over 30,000. Approximately 70 percent of the land area and 80 percent of the population is currently served by sanitary sewers. The City of Renton's collection system is municipally owned, operated and maintained and is managed by the City of Renton's Planning/Building/Public Works Department (Public Works). The City maintains 23 sewage lift stations; an additional six sewage lift stations are privately owned and maintained. Wastewater is discharged to METRO facilities at 55 locations within the City, from which it is conveyed to and treated by METRO's Renton Treatment Plant. The City of Renton system contains approximately 3,000 manholes and 10,187 customer connections. FIGURES 1, 2 and 3 illustrate the existing sewer system in plan and profile views. B. SYSTEM HISTORY Sanitary sewer facilities were first constructed in the downtown area of the City of Renton in 1910. Prior to that it was common practice to dispose of wastewater on-site or to directly discharge it to the local estuaries. By 1940 the City's population had grown to 4,800; wastewater was collected and treated in a large septic system located on the Black River channel. During the 1940s, federal housing was constructed in the City to accommodate workers employed by defense industries. By 1956 the wastewater collection system served a population of 14,800 people within the City's service area. By that time wastewater was treated in a secondary • treatment plant located near the current Renton High School Stadium. This treatment plant discharged treated wastewater to the Cedar River. In 1958 the Municipality of Metropolitan Seattle (METRO) was formed to solve the growing problem of pollution in Puget Sound, Lake Washington and surrounding waters. METRO developed a regional plan for wastewater collection and treatment facilities in 1959 and assumed operating responsibilities for the regional interceptors and waste treatment systems in 1962, including Renton's secondary treatment plant. The new secondary treatment plant was constructed between 1956 and 1962 near the intersection of Grady Way and Monster Road and discharged into the Duwamish Water Way. This location is the current site of METRO's Renton Treatment Plant, which serves as,one of the regional treatment facilities. The City of Renton sanitary sewers now discharge to these METRO facilities. • 2-1 • CHAPTER TWO C. SYSTEM COMPONENTS The purpose of a sanitary sewer is to convey wastewater from its source to a point of treatment. Since_the generation of wastewater can vary considerably, there is seldom any control over the volume of wastewater that must be conveyed at any particular time. For this reason the sanitary sewer system is designed to accommodate a wide range of wastewater flow rates. The best method for conveying wastewater is a gravity sewer system. A gravity sewer system is made up of collector sewers, which as their name implies, collect the wastewater from the various sources. These collector sewers then convey the wastewater to interceptor sewers, which convey it to the point of treatment. The sanitary sewer system must be capable of transporting all of the constituents of the wastewater stream, which include the suspended solids, floatable solids and liquid constituents. In general, most of the floating materials are carried along with'the flow stream; however, suspended-solids have a tendency to settle out of the waste stream, unless minimum carrying velocities are achieved. This requires that the sanitary sewers be constructed with a minimum slope to create a gravity flow which will result in a velocity that will continuously carry the suspended solids portion of the waste stream. Another major sewer system component, and typically the most vulnerable one, is the sewage lift station. A lift station is needed when the sanitary sewer system must overcome topographic restrictions that make it impossible or financially unfeasible to construct a gravity sewer. However, some lift station are temporary, used only until the gravity sewer system can be built. D. WASTEWATER COLLECTION BASINS The City of Renton is divided into six major wastewater collection basins, as shown in FIGURE 1, which consist of one or more subbasins. These collection basins and subbasins predominantly follow the natural drainage patterns of the Renton service area. The six major basins are 1) May Creek, 2) Lower Cedar River, 3) Lake Washington East, 4) Black River, 5) Lake Washington West, and 6) Duwamish Estuary. E. INTERCEPTORS AND COLLECTION SYSTEMS Interceptor are sewers that receive flow from collector sewers and convey such wastewater to a _ point for treatment or disposal. They are typically located in low lying or centralized areas in order to facilitate the gravity flow of the wastewater. The interceptors and all other sewers make up the collection system. Standards and guidelines for design and construction of sanitary sewers are detailed in Chapter 4. 2-2 • _ I Overview of Existing Sewer System .i The City of Renton has approximately 153 miles of gravity sewer within its service area as displayed in Plan View in FIGURE 1. Sewers shown in bold represent the major interceptors in the system. Those shown in gray represent the collection network. The sanitary sewer collection system is primarily comprised of 8-inch diameter sanitary sewers. The hydraulic profile, shown in FIGURE 2, illustrates how wastewater flows through the system. 1. EXISTING SEWERS The existing sanitary sewer system is constructed with a variety of different sewer sizes and pipe materials. TABLE II-1 summarizes the lengths of pipe for the different pipe diameters and materials. As illustrated in this table, a majority of the sanitary sewer system is constructed with 8-inch diameter pipe. This is consistent with the Department of Ecology criteria material for minimum sanitary sewer sizing. The majority of pipe material within the existing system is comprised of concrete and PVC pipe. The concrete pipe has been typically used for the older sewers and larger diameter sewers, while the PVC pipe has been typically used for newer sewer system installations up to 12-inches in diameter. • • � I 2-3 CHAPTER TWO TABLE II-1: SUMMARY OF SANITARY SEWER SIZES AND PIPE MATERIAL • PIPE SIZE SUMMARY • PIPE DIAMETER LENGTH PERCENTAGE 6-inch 2.8 miles 1.8% 8-inch 93.5 miles 61.1% 10-inch 5.3 miles 3.5% 12-inch 7.8 miles 5.1% 14-inch 0.2 miles 0.1% 15-inch 2.4 miles 1.6% 16-inch 0.1 miles • 0.1% 18-inch 2.2 miles 1.4% 21-inch 0.8 miles 0.5% 24-inch • 1.5 miles 1.0% Unknown 36.4 miles 23.8% TOTALS 153 miles 100% PIPE MATERIAL SUMMARY PIPE MATERIAL LENGTH PERCENTAGE Concrete Pipe 64 miles 41.8% PVC Pipe 33 miles 21.6% Vitrified Clay Pipe 8 miles 5.2% Lined ductile iron pipe 5 miles 3.3% Unknown pipe type 43 miles 28.1% TOTALS 153 miles 100% The City sanitary sewer system also contains approximately 3,000 manholes, which join the various links of sanitary sewer pipe. These manholes vary in construction type from old brick manholes to the newer precast concrete manholes. Many of the older manholes do not meet current code for safety such as manhole covers which are less than 24-inches in diameter. • 2-4 Overview of Existing Sewer System 2. INTERCEPTORS A list of the sanitary sewer interceptors within the Renton system is presented below. These interceptors are located in the following wastewater collection basins: MAY CREEK BASIN • Honey Creek Interceptor • Proposed May Valley Interceptor LOWER CEDAR RIVER BASIN • Tiffany Park Interceptor • South Highlands Interceptor • Maplewood Interceptor • Heather Downs Interceptor • Proposed Parker PUD Interceptor • Proposed East Renton Interceptor LAKE WASHINGTON EAST BASIN • Lakefront Force Main • West Kennydale Interceptor • North Highlands Interceptor • Proposed East Kennydale ( • Proposed Park Avenue BLACK RIVER BASIN • • SW 16th Street Interceptor • Talbot Hill Interceptor • Springbrook Interceptor LAKE WASHINGTON WEST BASIN • West Renton Interceptor • Tobin Street Interceptor • 2-5 CHAPTER TWO 3. METRO CONNECTIONS The Renton sanitary sewer system discharges wastewater to METRO sewer interceptors at 55 locations. The wastewater flow rates into each of these connections varies considerably, depending on the area served by the collection system. The major METRO connections for each subbasin are listed in TABLE TABLE II-2: MAJOR METRO CONNECTIONS SUBBASIN MANHOLE NO.

LIFT STATIONS Sewage lift stations are used to convey wastewater from a low point to a higher point through the use of a sewage pump and a pressurized force main. The City of Renton has 23 sewage lift stations within its sanitary sewer system. The location of these lift stations is shown in FIGURE 3. The most common type is a wet well mounted lift station in which the mechanical and electrical equipment are located above the ground surface and over a large manhole out of which the wastewater is pumped. The second most common type is a wet well/dry well configuration in which mechanical and electrical equipment are located underground in a sealed enclosure adjacent to a large manhole from which the wastewater is pumped. Two other types oflift stations include a submersible pump installation in which the sewage pumps are placed directly in the wet well, and a pneumatic injector in which wastewater is conveyed through a force main using pressurized air.. The City has one each of these types of lift stations. • 2-6 Overview of Existing Sewer System • Sewage lift stations are the most vulnerable element of a sewage collection system. Temporary lift stations are constructed when it is too costly, at that time ,to complete the gravity sewer system; permanent lift stations are constructed when it is either physically impossible or financially impractical to construct gravity sewers. - G. TELEMETRY AND CONTROL SYSTEM Successful operation of any municipal sewer system requires that the municipality maintain a comprehensive maintenance program and that they obtain accurate sewage flow rate information. Although many additional operation and construction elements are necessary for a complete and working system, maintenance and flow rate information are the keys to a successful operation. A telemetry and control system is' the means by which flow rates are measured and maintenance needs are updated. The City currently owns and operates an analog, signal-based alarm reporting system, manufactured by Stead Baggerly of Bellevue,Washington,which monitors each lift station. The system includes a master console, which is located in the City Shops, and a remote telemetry transmitter located in each lift station. H. OPERATION AND MAINTENANCE The current operation and maintenance program for the sewer utility consists of four elements: normal operations,emergency operations,preventive maintenance and staffmg. Normal operation of the sewer system is shared by the Engineering Division and the Operation and Maintenance Division. The program is described and evaluated in more detail in Chapter 6.

CHAPTER III OPERATIONAL POLICIES CHAPTER III OPERATIONAL POLICIES A. INTRODUCTION In addition to using flow rates and design criteria to analyze the existing system, each part of the system was evaluated against the specific policies that guide it. The policies, design criteria and standards used for planning and1 operating the sanitary sewer system are based on laws and policies that originate from the following seven sources, listed in descending order, from those with the broadest authority to the most narrow: • Federal Regulations - Environmental Protection Agency • State Regulations; - Department of Ecology • METRO Policies - Municipality of Metropolitan Seattle • City of Renton Ordinances - City Council • Administrative Policies - Mayor • Department Policies - Public Works Department • Utility Policies - Wastewater Utility Staff The laws and policies guide the wastewater utility's operations on a day to day basis, as well as its planning for growth and improvements. Their combined objective is to provide adequate, reliable sanitary sewer service at a minimum cost to the customer. The highest levels of policies--Federal Regulations, State Regulations,METRO policies, and City of Renton Ordinances--dictate requirements that are set by law. Other lower level policies cannot be less stringent or in conflict with those laws. The last three entities--Office of the Mayor, Public Works Department policies and Wastewater Utility Section--dictate requirements that supplement those laws. Those requirements are the specific policies summarized in this chapter. B. POLICIES The sewer system's ability to achieve the above laws, policies and standards is detailed in Chapter 5, System Analysis and Results. Chapter 5, System Analysis and Results and Chapter 6, Conclusions and Improvements, identifies where the system fails to meet those requirements and presents recommended improvements. It is important to note that if standards are set too low, customers will not be satisfied, and if standards are set too high, the cost of installing and operating facilities to meet such standards will be financially unacceptable. 3-1 • CHAPTER THREE • All policies and standards have the combined purpose of providing an acceptable level of service to the sanitary sewer customers. Service, therefore, is the most important principle that guides construction, operation, maintenance, and administration of the system. • The following are components of the City's service principle: • 1. Customer Service 2. Finance 3. Facilities 4. Organization The policies associated with each service category are identified in.this chapter. TABLE III-1 illustrates the relationship between each of these categories. • 1. CUSTOMER SERVICE POLICIES This section summarizes the customer service policies used to providea connection to the sanitary sewer system. Y Annexations (Source: City Policy, State Law) • City annexation policies will not conflict with state regulations and guidelines. Renton will follow state guidelines in the assumption of facilities in annexation areas. • Areas annexed without existing municipal sanitary sewer service will be served by Renton. • Areas annexed with existing sanitary sewer service must meet Renton Sanitary Sewer Standards. .. • Service to areas outside of the Citylimits without annexation will be evaluated by the City Council on a case by case basis. The Public Works Department mandates design standards and criteria for the areas requesting service without annexation. • City Council will consider and may allow sanitary sewer service outside City limits under the following conditions: • A no protest agreement for annexation is signed by those obtaining service. 3-2 • TABLE 3-1: CITY OF RENTON SANITARY SEWER UTILITY POLICY OUTLINE • • CITY POLICY OUTLINE • - -- • CUSTOMER SERVICE I FINANCIAL • FACILITIES ORGANIZATIONAL w w • 1 ANNEXATIONS COST OF SERVICE DESIGN CRITERIA STRUCTURE SERVICE INSIDE CITY RATES FOR OUTSIDE CITY MAINTENANCE LEVEL OF STAFFING TEMPORARY SERVICE LID'S/LATECOMER'S RELIABILITY RESPONSIBILITIES EMERGENCY SERVICE METRO CHARGES VULNERABILITY RELATIONSHIP WITH PLANNING BOUNDARIES JOINT USE OTHER DEPARTMENTS • • • ,00 co ti • 37.. .b • • �. y CHAPTER THREE • Service is necessary to protect the City's drinking water supplies, or service is necessary to convert from a failing septic tank and drainfield, or • the property served is within a drainage basin where service can be provided with gravity flow. • The full cost of service is paid by those served. • Boundary Review Board approval of service area boundaries is obtained. • City Council will consider annexations without assumption of existing sanitary sewer facilities under the following conditions: • The sanitary sewer facilities are operated and maintained by an adjacent municipal utility. • The adjacent utility has executed a service boundary agreement with the City. • The annexation area is located in a drainage basin that is better served by the adjacent utility. Mandatory Side-sewer Connections (Source: City Policy) • The City encourages all residents within the City to connect to public sewers. • Properties that are within two hundred feet of an existing sewer line who do not connect to them will be asked to pay a charge equal to the City's sewer charge. • Any party who has a connection available, but claims an exemption from • using it, is required to provide proof to the City that its septic system works and that it periodically pumps and conducts follow-up tests on it. • • Since failing septic systems pose a grave, health hazard to the City's groundwater, properties with such systems are required to connect to the public sewers. • The charge for failing to connect should be evaluated. • The City should research whether the low-income, infirm exemption applies to the hook-up charge and whether the City can financially assist people in that category. • • The City should reevaluate its policy on refusing to provide sewers outside of its limits when a threat to the City's aquifers exist. 3-4 Operational Policies Temporary Services (Source: City Policy) • Compliance with standards may be deferred for temporary sanitary sewer service. Emergency Service (Source: City Policy) • Compliance with standards may be deferred for emergency sanitary sewer service. • Policy criteria may be waived for emergency service. Planning Boundaries (Source: City Policy) • For planning purposes, the City will use sanitary sewer service boundaries established by agreement with adjacent municipalities. • Renton follows state law in assuming portions of adjacent sanitary sewer systems as a result of annexation. • Facilities will be planned and sized to serve natural basins to minimize the need for pumping. • Projected development and sewage flows will be based on adopted land use plans and policies. 2. FINANCIAL POLICIES This section details the financial i policies to be used to operate the sanitary sewer system. Cost of Service (Source: City Policy) • The utilities will use a rate setting process that complies with standards established by the American Public Works Association. • • Cost-based rates and additional charges established for the sanitary sewer utility . are those that 1) recover current, historical, or future costs associated with Renton's sanitary',sewer system and services, 2) are equitable charges to recover costs from utility customers commensurate with the benefits they receive, and 3) provide adequate and stable sources of funds to cover the current and projected annual cash needs of the sanitary sewer utility. • The existing customers of the sanitary sewer utility will pay the costs of operating 3-5 CHAPTER THREE and maintaining the facilities through user rates. In addition, user rates include a portion of the debt service incurred to finance the capital improvements and replacements of the utility. • New customers seeking to connect to the sanitary sewer system will be required to pay charges for an equitable share of the cost of the system. Revenue from these charges is used to finance part of the Capital Improvement Program. • Customers will be charged for supplemental, special purpose services through separate ancillary charges based on the cost to provide the service. Ancillary charges increase equitability and increase operating efficiency for services to customers. Revenue from ancillary charges will be used to offset operations and maintenance costs. • The utility will maintain information systems which provide sufficient financial and statistical information to ensure conformance with rate-setting policies and objectives. • There are two widely used, generally accepted methods for determining the total revenue requirements of a sanitary sewer utility - the cash basis and the utility basis. The sanitary sewer rates have been developed using the cash basis, a method commonly used by publicly owned utilities. • User charges must be sufficient to provide cash for the expenses of operating and • maintaining the utility. To ensure the fiscal and physical integrity of the utility, an amount should be set aside each year for capital expenditures from retained earnings. That is, an amount should be set aside to cover some portion of the depreciation of the physical plant. The amount may be transferred from the Sanitary Sewer Fund to the Construction Fund for general purposes or for specific purposes such as to create a reserve for main replacement. • A Working Capital Reserve will be maintained to cover emergencies, bad debts, and fluctuations in cash flow. • Customers should be classified as single-family, multi-family, commercial, industrial, governmental, and senior citizens. These are the existing customer classes for the utility. • The inflation rate will be based on information provided by the Finance Department. 3-6 Operational Policies • The large industrial users will be charged for services on the same basis as all • other users. • The utility will wise generally accepted cost allocation principles for all cost allocation purposes. • The utilities' fees and charges should be calculated for the service area as a whole. Rates will be thea same regardless of service location (except for the inside City/outside City distinction discussed later). Rates For Outside City (Source: City Policy) • For customers residing outside the City limits, sanitary sewer rates are 1.5 times the residential City rates. LID's/Latecomer's (Soull ce: City Policy, State Law) • Owners of properties that have not been assessed or charged an equitable share of the cost of the sanitary sewer system shall pay, prior to connection to the • system, one or more of four charges: latecomer's fees, special assessment charge, utility connection charge, or inspection/approval fees. METRO Charges (Source: City Policy), • Charges and fees levied by the Municipality of Metropolitan Seattle (METRO) shall be passed ori to customers. • 3. FACILITY POLICIES This section details the planning criteria to be used to establish an optimum behavior level and a standard of quality for the sanitary sewer system. Design Criteria (Source: City Policy) • All sanitary sewer facilities shall be designed to meet the minimum requirements and standards set forth in the "Criteria For Sewage Works Design" prepared by the Washington State Department of Ecology and Title 8, Chapter 5 of the City code. • Analysis and design criteria are detailed under Section C of this chapter. 3-7 CHAPTER THREE • Maintenance (Source: City Policy) • The City shall maintain the sanitary sewer system in a safe,reliable, and efficient operating condition with repairs and replacements provided on a scheduled basis that acknowledges a functional and economically useful life of the equipment and facilities. • Equipment breakdown repairs should be made even if overtime labor is involved. • Equipment should be replaced before it becomes obsolete. • Worn parts should be repaired, replaced, or rebuilt before they represent a high probability of failure. • Equipment that is out of service should.be returned to service-as soon as possible. • A preventive maintenance schedule shall be established for all facilities,equipment and processes. • Spare parts shall be stocked for all equipment items whose failure will impact 1) the ability to meet other policy standards, or 2) the inability to continue providing service to customers. • Tools shall be obtained and maintained to repair all items whose failure will impact the ability to meet other policy standards. • Dry, heated shop space shall be available to all maintenance personnel. • All maintenance personnel shall be trained in the procedures and techniques necessary to efficiently perform their job descriptions. • • Maintenance shall be performed by the sanitary sewer maintenance staff, and supervised by the Field Superintendent. • Written records and reports will be maintained on each facility' and item of equipment showing operation and maintenance history. • The City owns and shall maintain side sewer stubs. If a side sewer becomes plugged, the property owner shall first hire an independent plumber to investigate 3-8 Operational Policies the problem. If it is determined that the problem exists within the City-owned section of the side sewer, then the maintenance crews shall promptly respond and correct the problem. • • If an existing gravity sanitary sewer must be extended in order to make a side. sewer connection,'the property owner must extend the gravity sewer along the full extent of the property. • Restaurant and other food processing establishments shall install and maintain grease traps. Vulnerability ( Source: City Policy) • Vulnerability analysis will be performed to determine a reasonable "worst case" failure for each bain. The analysis will consider the failure of the interceptor and trunk sewers, failure of the largest mechanical component, and power failure to a single power grid. Joint Use (Source: City' Policy) • All joint use facilities must comply with Renton policy and design standards. • Joint use facilities located within the City will be maintained by the City of Renton. • Joint use facilities will be pursued only in those areas that improve reliability or • reduce operating costs. 4. ORGANIZATIONAL POLICIES • Structure (Source: City Policy) • The Wastewater Utility shall be operated as an enterprise utility (financially self supporting). • The Wastewater Utility shall consist of two divisions: planning/design and operations/maintenance. • • Wastewater Utility management is accomplished by the Public Works Department managers. 3-9 • CHAPTER THREE • The Wastewater Utility shall operate only the municipal sanitary sewer system. Stormwater, water, and other utilities are not administered or operated by the Wastewater Utility. • Wastewater Utility customer service is performed by the Public Works Customer Service Division (general) and by the Wastewater Utility staff (technical). Staffing (Source: City Policy, State Requirements) • The utility staff level is established by the City Council based on the utility requirements and financial resources of the City. • Personnel certification will comply with State standards. The Utility Engineer and Maintenance Supervisor shall be certified. • The City will support staff training. Responsibilities (Source: City Policy) • The Wastewater Utility has the responsibility for sanitary sewer system operation. ▪ Planning,design, operations and maintenance,records management, and customer service and construction will be accomplished by the Wastewater Utility. Relationship with other Departments (Source: City Policy) • The Finance Department is responsible for customer billing, payment collection, project cost reporting and fund activity reporting. • The Personnel Department is responsible for employee records, union labor negotiations, and salary schedules. • The Police Department is responsible for enforcing violations of City sanitary sewer ordinances. 3-10 CHAPTER IV LAND USE POLICIES, ADJACENT SYSTEMS & DESIGN CRITERIA . I I CHAPTER IV LAND USE POLICIES, ADJACENT SYSTEMS & DESIGN CRITERIA A. INTRODUCTION • This chapter describes the City of Renton's land use policies, the sewer system's connections with adjacent utility systems, and the sewer system's design criteria. It then describes how land use policies and design criteria; were used to develop saturation flow rates for a hydraulic computer analysis of the existing system. The City of Renton's land use policies and its sewer system are interconnected with adjacent sewer systems in several ways. Existing land use provides the basis for designing properly sized sewerage facilities,including trunks,interceptors, and lift stations. In most cases Renton's sewers are downstream, or at the receiving end of the effluent, from the systems adjacent to the City. Most of the basins served in part by the City are also served in part by other cities or districts. Therefore, proper planning for Renton's sewers requires.that the plans of these adjacent agencies be evaluated. B. STUDY AREA As described in Chapter 2 the City of Renton serves six drainage basins. These are: 1) May Creek, 2) Lower Cedar River, 3) Lake Washington East, 4) Black River, 5) Lake Washington West, and 6) Duwamish Estuary. Except for Lake Washington East, all of these basins are also served in part by another sewer agency. The extent of these basins is shown on FIGURE 1. _ May Creek Basin is partially served by King County Water and Sewer District No. 107. Service within the lower Cedar River Basin is also provided by Cedar River Water and Sewer District and Soos Creek Water and Sewer District. In addition to Renton, the City of Tukwila, City of Kent, and Soos Creek Water and Sewer District also provide service within the Black River Basin. Both Renton and the City of Tukwila provide service within the Duwamish Estuary. Parts of the Lake Washington West Basin are served by Bryn Mawr/Lakeridge Water and Sewer District and Skyway Water and Sewer District. The study area, shown in FIGURE 5, for this Comprehensive Sewer Plan Update was developed using a variety of criteria. Because many of the adjacent utilities have sanitary sewer facilities that border the Renton city limits, the study area for the most part, corresponds with the current city limits. Deviations from this norm did occur in the following areas: • Since Water District 90 does not currently provide sanitary sewer service within its service area, a considerable amount of annexation pressure exists in this area. Therefore, the study area was extended into the service area of Water District 90 out to the East Maplewood subbasin limits. 4-1 • CHAPTER FOUR • The City of Renton is currently negotiating with Soos Creek Water and Sewer District to revise the service area boundary along their common border. For this reason, the study area included the tentatively agreed upon service area boundary. • Natural boundaries in certain areas make the City of Renton the logical sanitary sewer provider to them. The study area includes the following areas of this kind: • the area lying south of May Creek within King County Water District 107, • the area to the east of the Green River within the City of Tukwila, and • the area within the southern portion of the Skyway Water and Sewer District and an area within the eastern portion of the Bryn Mawr/Lakeridge Water and Sewer District. C. LAND USE • 1. CITY OF RENTON Development in the service area must be in compliance with the City's Comprehensive Land Use Plan and policies, which represent a long-range plan for growth and physical development of the City. The current character of the City reflects the original Comprehensive Land Use Plan which was adopted in 1965 and revised in 1968. Under this plan, industrial and commercial development was directed toward the Central and Green River Valley areas to allow for further expansion of the City's business center. Residential growth under the plan was primarily directed toward the eastern areas such as the Highlands and Talbot Hill areas of the City, since the West Hill was already developed primarily with residences. A summary of the land use that resulted from this plan is presented in FIGURE 6. Review and updating of the Comprehensive Land Use Plan was initiated in 1975 to affect changes made in the economic,legislative, and land use philosophy of the City since the adoption of the original plan. To accomplish this updating, the original plan was divided into four planning areas: the Northeast Planning Area, the Southeast Planning Area, the Central Planning Area, and the Green River Valley Planning Area. Existing and proposed land use for each area was examined,revisions were proposed and hearings were held, with final revisions incorporated into the Revised Comprehensive Land Use Plan. Since 1975 all four Planning Areas have been examined, and Land Use Plans have been revised and adopted for each planning area. Since 1989 the City has been in the process of revising and updating the overall Comprehensive Plan, a process that will not be completed in time for inclusion in this document. 4-2 Land Use Policies/Adjacent Systems/Design Criteria Planned land use within the service area is based on the following City policy. Section 3.A of the Comprehensive Land Use Plan recommends maximizing the use of available utility and service resources in existing areas prior to allowing development of outlying areas. This policy section provides the framework for current land use development and is stated in TABLE IV-1. TABLE IV-1: SECTION 3.A OF THE COMPREHENSIVE LAND USE PLAN 3.A. LAND DEVELOPMENT OBJECTIVE: Growth and development should occur in a timely and logical progression of the existing urban area to maximize the use of existing services. POLICIES: 1. To minimize the necessity for redevelopment, premature development should only be allowed where it can be shown to be compatible with future use in the vicinity. 2. Development beyond the urban fringe should only be allowed • where it is a'consistent extension of urban services. 3. Vacant land surrounded by developed land should be given priority for development. 4. Land where adequate public utilities are available should be given priority for development. • 5. A balance of residential, commercial, and industrial areas should be encouraged. • 6. The upgrading and/or redevelopment of marginal areas should be encouraged. • 7. The City should identify its sphere of influence. { 8. Annexations i should have logical boundaries. 9. To reduce processing time and effort and provide for efficient use of existing public facilities, large annexations should be encouraged. ; 10. Annexations that are economically advantageous should be encouraged. 11. Development requirements should be definite and reasonable. 4-3 • CHAPTER FOUR • The following objectives of the Comprehensive Land Use Plan are based on the policy statements in TABLE IV-1. • - • To manage growth and physical development in the City and surrounding unincorporated areas. • To encourage growthin existing areas where the patterns of development are already largely set. • To direct expansion of residential, commercial, and industrial developments into areas where land, utilities, access, and community facilities are available with the capacity to accommodate the projected growth. • Allow higher dwelling densities in areas capable of supporting a higher level of development and lowering densities in areas where facilities are limited. The existing land uses within the City have been classified into a variety of categories for the purposes of planning and mapping. The categories used are listed in TABLE IV-2 and the corresponding number of acres in each land use category is listed in TABLE IV-3. A summary of the information in TABLE IV-4 is shown in graph form in FIGURE 4.

The original City was settled in the broad floodplain at the confluence of the Cedar and Black Rivers along the shore of Lake Washington. This area continues to be the heart of Renton; its industrial uses, the airport along Lake Washington and the Central Business District at the foot of Renton Hills are interspersed with older,,single-family housing and small apartment complexes. 1 On the hills and plateaus surrounding the core area, are residential areas, originally developed in the county and annexed to the City. Single-family residential neighborhoods are concentrated in the Highlands, Kennydale Hill, West Hill, Earlington Hill, Talbot Hill, and the ridges along ti Maple Valley. •Along the edges of the single-family neighborhoods and the transportation corridors are concentrations of multi-family housing. Significant concentrations exist along NE 4th Street, NE Sunset Boulevard, SW Sunset Boulevard, and Benson Road So. In addition to the Central Business District, commercial areas are concentrated along the major arterials and freeway exchanges, including Rainier Avenue, Grady Way, Sunset Highway, Bronson Avenue, NE 4th Street, the NE 44th Street exit, and SW 43rd Street. The Green River Valley was annexed to Renton in the late 1950s with the intention of developing a second industrial base. This area, which was originally the northern end of a long farming belt along the Green River, now includes a few residual houses and a significant concentration of manufacturing, warehousing, and office park development. A hub of commercial services is located in the southeast corner of the City limits. • Valley Medical Center dominates the land uses along the southern portion of Talbot Hill. Surrounding the hospital is a concentration of support facilities, including medical and dental offices and laboratories. Parks in the Renton area tend to be located along river channels and lake shores. Many parks are located along the Cedar River, including: Liberty Park, Maplewood Golf Course, Cedar River Park, Jones Park, and the Cedar River Trail. Gene Coulon Memorial Beach Park and Kennydale Beach Park are situated directly on the shore of Lake Washington. The City is currently bounded in, the south and west by Kent and Tukwila, and to the north by Lake Washington. Future land use is primarily a function of the location of existing vacant land within the City and the rezoning of existing designations. The zoning designations for the vacant land within the City are listed ins TABLE IV-4. 4-7 CHAPTER FOUR 2. UNINCORPORATED KING COUNTY Land use within the unincorporated portions of the study area is controlled by the 1985 King County Comprehensive Plan. All of the study area in unincorporated King County is designated "urban." Urban areas are those areas where most new housing and jobs will be located and where most public spending for facilities, services, and open space is normally focused. Comprehensive Plan Policies R-201 and R-202 establish a goal of achieving an average density of seven to eight dwellingunitsper acre within the urban area. Such an overall density.goal g cannot be achieved without providing sanitary sewer service to residential development. King County is divided into smaller planning areas called Community Planning Areas. Two community plans, Newcastle and Soos Creek, cover most of the unincorporated areas within the study area of this Plan. The Soos Creek Community Plan was adopted in November 1979 and is currently in the process of being updated. According to County staff, it is expected that a revised Soos Creek Community Plan will be forwarded to the King County Council for review and adoption in 1991. The Newcastle Community Plan was adopted in 1983. The update process for the Newcastle Community Plan has not been scheduled. 3. SPHERE OF INFLUENCE The City of Renton has entered into an interlocal agreement with the Cities of Bellevue and Issaquah to establish sphere of influence lines. This agreement was signed by the three jurisdictions in 1979. The sphere of influence agreement places responsibility for long-range planning with the City of Renton within its sphere of influence 4. ADJACENT UTILITY SYSTEMS/JOINT USE AND SERVICE AGREEMENTS The City has entered into several joint use and service agreements with neighboring districts and private customers when it has been economically beneficial. A list and a summary of these joint use and service agreements is presented below. The full text for each of these agreements is presented in Appendix B. • The Tiffany Park Interceptor Joint Use Agreement with the Soos Creek Water and Sewer District. • Apollo School Lift Station Service Agreement with King County Water District 90. • Earlington Elementary School Service Agreement. • King County Water District No. 107 Utility Franchise Agreement. • King County Water District No. 107 Joint Use Agreement. • King County Sewer and Drainage District No. 4 Agreement. . • City of Kent Agreement. • Cascade Sewer District Service Boundary Agreement. • Bellevue/Issaquah/Renton Sphere of Influence Agreement 4-8 Land Use Policies/Adjacent Systems/Design Criteria The City is surrounded by eight adjoining utility entities, seven of which provide sanitary sewer services. These eight utility entities are shown on FIGURE 7. It is evident that some sewer franchise boundaries overlap with the City limits. These areas•are also shown in FIGURE 7. The study area for the City's Comprehensive Sewer Plan is shown on FIGURE 5. It includes • parts of drainage basins within adjoining utility entities. Areas which may be considered for service boundary adjustments are also shown in FIGURE 5. a. KING COUNTY WATER DISTRICT NO. 107 King County Water District No. 107 provides sewer service in part of the May Creek Basin. The District adopted a Comprehensive Sewer Plan in 1988. Their plan for serving May Creek Basin includes diverting approximately 1,000 acres from the May Creek Basin to the Coal Creek Basin on an interim basis. This plan is based upon two assumptions: first, that it would be too difficult and expensive to construct a May Valley Interceptor at this time, and second, that the City of Renton's service in the southern part of the Basin is adequately provided by the Honey Creek Interceptor. In order to accomplish this diversion, the District is proposing to construct three lift stations and to complete a Coal Creek Interceptor Improvement Project. The sewer franchise boundary for King County Water District No. 107 is shown on FIGURE 7. Two small service area overlaps occur because the City annexed part of the District, but the District has not yet redrawn its boundaries. The District and the City have entered into joint use agreements in the past in order to provide for the construction of sanitary sewer facilities. Joint use agreements will continue to be needed as the May Creek Basin develops.. The existing service area gap which is located south of May Creek and east of Honey Creek may best be served-by the City. This service area gap is shown on FIGURE 5. b. KING COUNTY WATER DISTRICT NO. 90 King County Water District No. 90 does not currently provide sanitary sewer service. However, the District does have a sewer franchise boundary which is shown on FIGURE 7. The District had a Comprehensive Sewer Plan prepared in 1970,but has not proceeded with the formation of a sewer district due to opposition from the community. Since the District is reluctant to provide sewer service within its franchise boundaries,the City is experiencing annexation pressures from property owners adjacent to the City 4-9 . S CHAPTER FOUR I limits. These annexation requests are for the purpose of obtaining sewer service. For this reason and due to natural drainage patterns, the study area shown on FIGURE 5 extends outside the current City limits. c. CEDAR RIVER WATER AND SEWER DISTRICT Cedar River Water and Sewer District provides service to parts of the Lower Cedar River Basin. However, only a small fraction of the wastewater from Cedar River Water and Sewer District ultimately flows through the City of Renton's system by flowing through the Soos Creek Water and Sewer District. The majority of sewage from Cedar River Water and Sewer District flows directly into METRO's Cedar River Interceptor located along the Maple Valley Highway. The District's last Comprehensive Sewer Plan was adopted in 1983. According to the District's engineer, a revised Sewer Plan for Cedar River Water and Sewer District is expected in 1991. The sewer franchise boundary for Cedar River Water and Sewer District is shown on FIGURE 7. A service area overlap occurs as a result of the City's recent annexation of the park area located east of the Maplewood Golf Course. Currently, no sewerage facilities are required; the City will provide these services. The Wasmeta Park area is a service area gap between the City and the District. Currently no sanitary sewer facilities exist within this area. If sewer service is needed or required, the City should provide this service, due to its proximity on the north side of the Cedar River. d. SOOS CREEK WATER AND SEWER DISTRICT Soos Creek Water and Sewer District adopted a Comprehensive Plan in 1987. The plan acknowledges several service area overlaps with the City of Renton. The District also proposes providing sewer service within portions of the Black River Basin within the City of Renton. Renton has an agreement with Soos Creek Water and Sewer District for joint use of a sewer interceptor in the Tiffany Park Subbasin. .The Springbrook Interceptor, owned by the Soos Creek Water and Sewer District located on So. 192nd Street, could provide service to the southernmost portions of the City of Renton. Soos Creek Water and Sewer District currently has a sewer line in 96th Avenue So. north of So. 192nd Street within the City limits. Its 1987 Comprehensive Plan shows the District providing service on both the east and west sides of 96th Avenue So. within the Renton city limits. 4-10 Land Use Policies/Adjacent Systems/Design Criteria _ The sewer franchise boundary for Soos.Creek Water and Sewer District is shown on FIGURE 7. Several service area overlaps occur because the City and the District are currently negotiating revisions to the service area boundaries between them. These proposed revisions are shown on FIGURE 5. This agreement proposes that the City serve some areas outside the City limits, and that the District serve some areas inside the City limits. e. CITY OF KENT SW 43rd Street is the principal dividing line between the cities of Renton and Kent. Renton has an agreement with Kent to serve a small area south of SW 43rd Street east of 72nd Avenue So. and west of the Puget Sound Electric Railway right-of-way. The City of Kent Comprehensive Sewer Plan was adopted in 1980. The Renton and Kent City limits adjoin each other as shown on FIGURE 7, and there are no service area overlaps or gaps between the two entities, except for that one small area. f. CITY OF TUKWILA A portion of the City of Tukwila east of the Burlington Northern Railroad and south of Longacres is served by the City of Renton. Tukwila also discharges from a lift station into the METRO Sewer System within the City of Renton along SW 10th Street. Tukwila prepared a Comprehensive Sewer Plan in 1984. This Plan shows the extension of sanitary sewer service by the City of Tukwila into the City of Renton in the vicinity of Longview Avenue So. and SW 33rd, ultimately connecting into the existing Renton system along the railroad right-of-way. The 1984 Tukwila Plan also shows relocating two sewer mains north of I-405 in the vicinity of 72nd Avenue So. and SW 10th Street within the City of Renton in order to eliminate a pump station within the City of Tukwila. The Renton and Tukwila City limits adjoin each, other as shown on FIGURE 7. However, a natural service area boundary between the two entities is the Green River, which might be considered for a service area adjustment as shown on FIGURE 5. g. SKYWAY WATER AND SEWER DISTRICT A copy of the 1984 Comprehensive Sewer Plan for Skyway Water and Sewer District was obtained from the District's engineer. The Plan appears to be a compilation of previous plans that were done for King County and the predecessor to Skyway Water and Sewer District. It appears, however, that no facilities within the Skyway service area directly • discharge to, or would affect, facilities within the Renton sewer system. 4-11 CHAPTER FOUR The Skyway Water and Sewer District does not have a sewer franchise boundary according to records provided by King County. However, the franchise boundary may still be under the former King County Sewer and Drainage District No. 4. The service area from the District's Comprehensive Sewer Plan is shown on FIGURE .7. Approximately 60 percent of the District is served with sanitary sewer facilities. A large area within the District, as well as in the service area gap to the south of the District, could be served by gravity to the Renton sanitary sewer system. This area is shown on FIGURE 5. h. BRYN MAWR-LAKERIDGE WATER AND SEWER DISTRICT According to maps provided by the District, Bryn Mawr-Lakeridge Water and Sewer District serves a small area of Renton along Rainier Avenue near So. 117th Place. Sewage from Bryn Mawr/Lakeridge discharges into the METRO System within the City of Renton at the north end of the Renton Airport. The sewer franchise boundary for Bryn Mawr-Lakeridge Water and Sewer District is shown on FIGURE 7. The eastern part of the District could be served by gravity to the Renton system. This area is shown on FIGURE 5. However, unless this area is annexed to the City; there is no advantage to this service area transfer. D. ANALYSIS AND DESIGN CRITERIA This section presents the design criteria for sanitary sewage collection system analysis and design. Analysis is necessary to determine the adequacy of the existing system and to identify needs for future facilities. The analysis and design criteria are based on "Criteria For Sewerage Works Design" prepared by the Washington State Department of Ecology, the Municipality of Metropolitan of Seattle (METRO), the City of Renton Standards, actual water usage records, and other accepted engineering criteria and standards for sanitary sewer design and construction. 1. WASTEWATER FLOW RATES - DEFINITION Wastewater in the service area is generated by the population and by non-residential users within it. The Renton Comprehensive Land Use Plan identifies eleven, separate land use categories. For sanitary sewer planning purposes, these eleven categories were used to determine wastewater flow rates for the hydraulic computer model. The eleven land use categories are listed in TABLE IV-3. Eleven saturation land use populations were determined by calculating the areas of each designated land use category. This was accomplished by assigning land use designations to all parcels within a land use boundary on a computer base map that'was used for producing the 4-12 I I Land Use Policies/Adjacent Systems/Design Criteria figures for this plan. Saturation was defined as the point at which development is complete within a land use designation. 2. WASTEWATER FLOW CRITERIA • Wastewater flows can be divided into four major components, which are 1) domestic wastes, 2) industrial wastewater, 3) infiltration, and 4) inflow. The wastewater flow criteria used for each or these four components is presented in TABLE IV-5. a. DOMESTIC WASTEWATER Domestic wastewater flows are essentially equal to winter-time water consumption. Domestic wastewater flows are typically established on a per capita basis. The average domestic wastewater flow used for analysis and design of the sanitary sewer system is 80 gallons per day per person. b. COMMERCIAL/INDUSTRIAL WASTEWATER Commercial and industrial wastewater is defined as the wastewater generated from a specific commercial or industrial operation. Commercial and industrial wastewater does not include waste generated by employees of the industry, which are considered domestic waste and excluded from]this category. c. INFILTRATION Infiltration is the entrance of groundwater into the sanitary sewer system through cracks, pores, breaks, and defective joints in the sewer piping network. Additional infiltration also results from the entrance of storm- water through manhole covers. The quantity of water that may infiltrate into a sanitary sewer system depends upon many variables, such as the age of the system, materials used in construction, and the service area's hydrology, soils and groundwater level. However, the design of the sewer system, including mains, laterals, and individual connections, along with inspection during construction, will have substantial impact on the quantity of infiltration. Due to improvements in construction materials and practices, systems installed after 1960 generally show a decrease in the quantity of groundwater infiltration. The use of non- porous piping materials and rubber-gasketed type joints will help reduce infiltration and will improve the condition and life of the sanitary sewer system. The design allowance for infiltration is shown in TABLE IV-5. 4-13 CHAPTER FOUR • TABLE IV-5: WASTEWATER FLOW CRITERIA Average Domestic Sewage Flow: 80 gals/day/person Average Population Density 2.40 person/dwelling unit single-family (U.S Census Bureau, 1980): 2.20 person/dwelling unit multi-family Residential Density: Single-Family Residential 6 dwelling units/acre Low-Density, Multi-Family Residential 12 dwelling units/acre Medium-Density,Multi- Family Residential 18 dwelling units/acre High-Density,Multi- Family Residential • • 24 dwelling units/acre Commercial and Industrial Sewage Flows': Light Industrial 2800 gals/acre/day (gpad) Heavy Industrial site specific Commercial 2800 gpad Office 2800 gpad Recreation 300 gpad Green Belt 0 gpad • Public 600 gpad Manufacturing Park 2800 gpad Infiltration and Inflow (METRO): Peak Infiltration 700 gpad Peak Inflow 600 gpad Peaking Factors • System Average 2.0 x Depth/diameter ratio 0.70 * Design flow criteria vary considerably, depending upon land use • 4-14 Land Use Policies/Adjacent Systems/Design Criteria d. INFLOW - Inflow refers to direct flows of stormwater into sanitary sewer systems through hookups _ - from stormwater collection facilities and illegal connections. Stormwater inflow is due mainly to unauthorized connections to the sanitary sewer system. The enforcement of regulations banning the illegal connections to the sanitary sewer system along with continued efforts to identify and correct previously unauthorized connections minimize stormwater inflow. The design allowance for stormwater inflow is shown in TABLE IV- i 5. 3. SANITARY SEWER DESIGN CRITERIA All sewer lines within the City of Renton shall be designed in accordance with good engineering practice by a professional engineer with minimum design criteria presented in Chapter 2 of the "Criteria for Sewerage Works Design", prepared by the State of Washington Department of Ecology, October 1985, or as superseded by subsequent updates. This chapter includes standards and guidelines for design considerations (minimum pipe sizes, pipe slopes and wastewater velocities),maintenance considerations,estimating wastewater flow rates,manhole locations,leak testing and separation from water, pipelines. These criteria have been established to ensure that the sanitary sewers convey the sewage and protect the public health and the environment. The sewer lines shall also conform to the latest City of Renton Standards and Specifications. Detailed standards are included in Title 8, Chapter 5 of the City Code which is presented in Appendix D. Requirements relating to design are listed below. a. DESIGN LOADING FOR SANITARY SEWER FACILITIES Sanitary sewer system flows are composed of residential, institutional, commercial, and industrial sewage, along with infiltration and stormwater inflow. Sanitary sewer systems must be capable of conveying the ultimate peak flows of these wastewater sources. No overflows shall be permitted. b. DESIGN PERIOD 1 The design period is the length of time that a given facility will provide safe, adequate • and reliable service. The period selected for a given facility is based on its economic life, which is determined by the following factors: the structural integrity of the facility rate of degradation,cost of replacing the facility, cost of increasing the capacity of the facility, and. the projected population growth rate serviced by the facility. Collection and interceptor sewers are designed for the ultimate development of the contributing area. The life expectancy for new sanitary sewers, using current design practices, is in excess of fifty years. • 4-15 • CHAPTER FOUR c. DESIGN OF SANITARY SEWER FACILfl1ES Allowable sewer pipe shall be ductile iron, cast iron, PVC, or concrete. For normal - depth, PVC is generally preferable, because it has longer laying lengths, which results.in fewer joints, reducing the potential for infiltration. Gravity sewers are sized to provide capacity for peak, wet-weather flows. The smallest diameter sewer allowed is 8-inches. All sewers will be laid on a grade to produce a mean velocity when flowing half-full of at least 2 feet per second. Manholes will be at least 48-inches in diameter and will be spaced at intervals not to exceed 400 feet on sewer lines 15-inches in diameter or less, and 500 feet on sewer lines 18-inches in diameter or larger. The design parameters are summarized in TABLE IV-6. d. ROUGHNESS COEFFICIENT The Manning equation shall be used to design and analyze wastewater flow characteristics of the sanitary sewers. The Manning roughness constant [n] shall vary depending on the pipe material. Typical values are summarized in TABLE IV-6. e. REFERENCE DATUM The King County Aerial Survey (K.C.A.S.) is the common datum used within the City of Renton for design and construction of sanitary sewer facilities. f. SEPARATION BETWEEN SANITARY AND OTHER FACILITIES The Department of Ecology requires separation of water and sewer facilities for health reasons. Sanitary and storm sewer facilities shall have basic separation requirements for construction purposes. A minimum horizontal separation of five(5) feet between sanitary and other facilities shall be maintained. Wherever possible, a horizontal separation of seven (7) feet is desirable. These distances are measured edge to edge. g.. HYDRAULIC ANALYSIS The sanitary sewer system hydraulic analyses will be performed using the City's hydraulic computer model. All new developments, with the exception of developments involving less than five single-family residences, will require an analysis. The developer shall be responsible for paying the cost of the analysis of the sanitary sewer system. If the analysis concludes improvements need to be made, the developer and the City may need to negotiate about who will pay the costs. 4-16 1 ^ Land Use Policies/Adjacent Systems/Design Criteria • TABLE IV-6: SANITARY SEWER DESIGN CRITERIA • Sanitary Sewer Sizing Peak Wet-Weather Flow Minimum Sewer Size ! 8-inches in Diameter Pipe Materials PVC Reinforced Concrete Pipe Cement Lined Ductile Iron Cement Lined Cast Iron Manholes Maximum Spacing 400 feet Minimum Manhole Size 48-inches in diameter • - Minimum Clear Opening 23-inches in diameter .

LIFT STATION DESIGN CRITERIA Sewage lift stations within the City of Renton shall be designed in accordance with good engineering practice by a professional engineer using the minimum design criteria presented in Chapter 3 of the "Criteria For Sewerage Works Design", prepared by the Washington State Department of Ecology,October 1985, or any subsequent updates, and shall conform to the latest 4-17 • CHAPTER FOUR • City of Renton standards and specifications. Detailed standards are included in Title 8, Chapter 5 of the City Code, which are presented in Appendix D. Requirements relating to the design are listed below. • a. DESIGN LOADING FOR LIFT STATIONS Lift stations shall be designed to handle the peak, wet-weather flow from the contributing area. All lift stations shall have a minimum of two pump units, each with the capacity to handle the expected maximum flow. b. DESIGN PERIOD The design period for lift stations shall take into consideration long-term needs, replacement or expansion difficulties, service area growth rate and useful life. A lift station should have a minimum design period of twenty years for the facility and ten years for mechanical and electrical equipment. Consideration should be given to longer design periods for lift stations that are expected to serve an indefinite life. Consideration must also be given to the ability of the consumers to pay for the facilities. c. DESIGN OF LIFT STATION FACIL ES Lift stations shall be designed with a minimum of two pumps,both of which have the capacity to convey peak, wastewater flow rates. If wide variations in wastewater flowrates are expected into the lift station, then consideration should be given to the use of three or more pumping units. If three pumps are used, two of them must have the capacity to convey peak, wastewater flow rates. Each pump shall be capable of passing spheres of at least 3-inches in diameter. Each lift station will be provided with either an on-site or portable power backup. A lift station designed for portable power backup will be provided with sufficient wet-well storage to allow adequate time for City maintenance personnel to transport setup, and provide the necessary backup, during a power outage. Wet-well storage will be designed • on the basis of the peak, wet-weather flow. Force mains shall be sized to maintain a minimum velocity of 2 feet per second. The force main shall have a maximum velocity of 10 feet per second when all pumps are operating together. Regardless of these velocity criteria, minimum size shall be 4-inches in diameter. • 4-18 Land Use Policies/Adjacent Systems/Design Criteria • + - 5. ELIMINATION OF LIFT STATION FACILITIES Lift station facilities are typically eliminated through the development of the gravity sewer system. Highest priority should be given to elimination of lift station facilities because their high degree of vulnerability and high operation and maintenance costs. These considerations include environmental risks, life-cycle costs, lift station impacts on downstream sanitary sewer facilities, vulnerability to vandalism, and lift station accessibility. • • • • 4-19 CHAPTER FOUR FIGURE 5: . 4-20 J I ... e..„ MM HIGH DENSITY I ( l, 0:116,.,,,,..... un tSINGLE FAMILYMULTI-FAMILY w '4(�■ n .

INTRODUCTION This " chapter presents a detailed analysis of the existing system and its recommended improvements. Three system components--the wastewater collection system,lift stations and the telemetry and control system--are identified and described, and the results of either their hydraulic or structural analysis are presented. Other deficiencies that do not fit under one system component are presented at the end of this chapter. Many sections of the existing sanitary sewer system have problems which fall into four categories: deficient capacity, aging pipes, infiltration and inflow, and combined sewers. Capacity problems in the existing sanitary sewer system have been identified using a hydraulic computer model. The hydraulic analysis was conducted by entering saturation wastewater flow rates in a computer model of the existing system to determine if it could adequately convey them. Capacity problems do occur throughout the system in various degrees and are a result of inadequate pipe sizes or slopes. • Much of the existing sanitary sewer,system was installed during the 1940s and 1950s as a federal program to provide housing for workers at the Renton Boeing Plant. Many of these sewers have reached the end of their useful economic life and require replacement. Many of them are in the North Highlands and South Highlands Subbasins. The City of Renton is currently in the process of replacing these aging sanitary sewers. Infiltration and inflow occur in all sanitary sewer systems. Infiltration is defined as water entering the sanitary sewer system through pipes, joint connections, manhole covers and walls. Inflow is defined as water discharged to the sanitary sewer system through connections to roof drains, yard drains, foundation drains, and cross connections with storm sewers and combined sewers. The combination of both infiltration and inflow can be:a major portion of the total wastewater flow which must be carried by the sanitary sewer system. Infiltration and inflow problems in an existing sanitary sewer system can be studied to determine their effect. Many infiltration and inflow problems can be corrected through grouting of existing pipes and manholes, replacing damaged pipes, and eliminating illegal connections to the sanitary sewer system. Combined sewers are designed to carry both stormwater and wastewater within a single system, which current design practices in the City of Renton do not allow because it causes stormwater, which is relatively clean, to be treated along with wastewater. Combined sewer systems within the City have been replaced with separate sanitary and storm sewer systems,except for one along the lakefront in the Kennydale area. 5-1 • . CHAPTER FIVE 1. HYDRAULIC ANALYSIS A hydraulic computer model of the City's sewer system was developed as a part of this plan update. The purpose of this model was to 1) evaluate the existing sanitary sewer system and.to determine areas of capacity constraint, and 2) to provide a tool for planning future improvements. The hydraulic computer model was created using a software package designed by Specialized Software Products, Inc., of Tukwila, Washington. Two basic kinds of data were needed for the computer model: physical data and wastewater flow data. The physical data of the sanitary sewer system was taken from as-built drawings and other records provided by the City. Physical data was only available for 60 to 70 percent of the sanitarysewer system. As a result the unmodelledportion of the sanitarysewer system cannot Y Y be evaluated using this computer model. The physical data entered into the computer model included manhole numbers, pipe invert elevations at each manhole, and pipe length, diameter, and material type. Physical data not entered was the age or date of construction of the various system components. The wastewater flow rates entered into the computer were based on estimated saturation conditions because those are the basic criteria around which sanitary sewer facilities are designed. Domestic wastewater flow rates were determined by calculating land use designations for the entire City. The wastewater flow rate criteria set for each land use designation is summarized in TABLE IV-3. The entire sanitary sewer system was first divided into sections and those sections divided into their land use designations. The total area of each land use designation within each section was calculated and then used to determine the domestic wastewater flow rate and infiltration and inflow data. The resulting flow rates and data were then divided equally amongst the sanitary sewer manholes within that land use designation. Pump flow rates from each of the lift stations were determined through.review of the operations and maintenance manuals, and this flow data was distributed to the appropriate manholes. The hydraulic computer model output was developed through a mathematical synthesis of the physical data and wastewater flow rate information which was entered into the model's data base for each pipe section. The maximum capacity of each pipe section was determined using the Manning's equation. A depth to diameter ratio of 0.70 was used to describe the maximum, desired hydraulic condition within a pipe section. The Manning's co-efficient for the various pipe materials is listed in TABLE IV-6. The slope used in the Manning's equation was calculated by the computer model using the invert elevation of the upstream and downstream manholes. The expected peak, wet-weather flow rate at saturation was calculated using the various flow rates entered onto the model data base. A peaking factor of 2.0 was applied to the domestic flow rate entered into each manhole. The peak, domestic flow rates, infiltration and inflow, and lift 5-2 System Analysis and Conclusions • station flow rates were then summed downstream through the entire basin. The model output includes the peak, wet-weather flow rate and maximum velocity for saturation conditions. The hydraulic analysis of the existing sanitary sewer system involved several steps. Firsts a comparison between the peak, wet-weather flow rates and the maximum capacity of each pipe section was made. A pipe section was determined to be over capacity if the ratio of the peak, wet-weather flow rate to the maximum flow rate was over 70 percent. This provided a safety factor which would help account for variations in the Manning's co-efficient and missing data not entered intothe computer data base. The second step identified the pipe sections 'with adverse pipe slopes (those pipe sections where the upstream manhole is lower than the _ downstream manhole), and the third step identified pipe sections 'which were constructed with inadequate slopes to achieve carrying velocity. This model will be used by the City in the future to evaluate changes to the existing system or additions to the system during the design phase of each sewer project. However, to increase the reliability of the model output, it is necessary that the City generate the physical data for the remaining sewer system that is not currently modeled. In addition, the existing physical data and wastewater flow data entered in the current model should be checked and verified. Finally, a model report should be prepared in order to document the information used in developing the model and to generate a complete print out of both the input data:and the output results. 2. STRUCTURAL ANALYSIS A structural analysis is a visual inspection of the existing system either by a video camera or an actual inspection during normal operations and.maintenance. The Sanitary Sewer Maintenance Division owns and operates its, own sewer video inspection equipment. At this time, the video equipment is used approximately one day per week. Video inspections have been organized and documented since 1988. The video inspection averages approximately 1500 feet per day. The inspection process requires hydraulic jet cleaning of the sanitary sewer section prior to the video inspection. After completion of the video inspection, roots are cut and cracks are sealed, if necessary, before proceeding to the next section. The video inspection requires three people to operate. If traffic control is necessary, two additional people are required. At the current rate, it will take twelve years to video inspect all existing sanitary sewers. 'It is recommended that sewers near the end of their useful life be video inspected every five years. All other sewers should be inspected every ten years. • Currently, the video tapes taken by the maintenance crews are stored and cataloged at the City Shops. However, sanitary sewer video tapes of new additions are stored in uncataloged boxes 5-3 CHAPTER FIVE which are then placed in the City's archives. The City should catalog all sanitary sewer video tapes using a computerized data base and store them in,a single location for easy retrieval. • B. - SYSTEM-WIDE CONCERNS • 1. METRO - INTERCEPTOR SURCHARGE During peak flows,METRO will use its interceptors for storage of wastewater and for controlling flows in the Renton Treatment Plant. This results in surcharging of the METRO Interceptors. METRO reserves the right to surcharge its interceptors to an elevation of 22 feet. METRO has never reached this extreme; however, the City has experienced a sewer surcharge problems in the low lying areas. The surcharge elevation of 22 feet is shown on the Sanitary Sewer Hydraulic Profile (FIGURE 2). This hydraulic profile illustrates that the City's sanitary sewers would be affected by METRO's surcharging, because their inverts are below the 22-foot elevation. As a result of METRO's surcharging, it is possible that additional wastewater could overflow in low lying areas through manhole covers and side sewer connections. The City has not designed facilities to accommodate a sewer surcharge to an elevation of 22 feet. The City's current position is that METRO is responsible for providing adequate capacity within its interceptors and wastewater treatment facilities. In addition, the City considers METRO to be responsible for proper effluent disposal. During the preparation of this Comprehensive Sewer Plan, no analysis was made of the effect of METRO's surcharging on the City's sewer system. METRO should conduct such a study to identify areas of potential risk and alternatives to mitigate this problem. 2. ADJACENT UTILITY SYSTEMS For purposes of this plan, all of the comprehensive plans for the-adjacent utility systems described in Chapter 4 were examined. This plan's analysis used their predictions for the future capacity they will need when they convey wastewater through Renton. However, adjustments to the City's interceptors may need to be made as these systems further clarify their needs. The City of Renton has several agreements with adjacent utilities that allow joint use of facilities within the City. It is important that these adjacent utilities are restricted to the volume of wastewater discharged to the joint use facilities. If capacity problems become evident, through visual inspection or flow measurements, then the City and the adjacent utility should work together to investigate the potential sources both inside the City and within the adjacent utility . to correct the problem. • 5-4 System Analysis and Conclusions 3. STRUCTURAL PROBLEMS The following is a discussion of specific problems that are associated with the gravity sanitary ! _ sewer system in the City of Renton. • AGING SEWERS Many of the gravity sewers within the central business district and the Highlands were constructed in the 1940s as a result of housing construction during the war for the Boeing plant in Renton. Many of these sewers have reached their design life expectancy (approximately 50 years); as these sewers approach the end of their useful life, increased maintenance and structural inspections should occur to locate and prevent pipe failures. This comprehensive plan identified some of the older sewers and has established a capital improvement program to replace and upgrade them. The City should continue this process. REVERSE SLOPES AND PIPE SAGS A major maintenance problem, associated with sanitary sewers that are laid with a reverse • slope, or have a sag due to improper construction or differential settlement, is that they require periodic cleaning to remove debris. There are approximately 90 such sewer sections within the City. ROOT PROBLEMS Tree roots cause problems in sanitary sewers by penetrating and cracking sanitary sewer pipe joints to feed on wastewater. Tree roots can also create blockages, resulting in backed-up sewers. The City has approximately 30 sections of pipe which require routine, root cutting maintenance to prevent wastewater backups and reduce pipe damage. GREASE PROBLEMS Grease problems are typically associated with major food processing operations, the majority of which are restaurants where grease is a component of the wastewater. Many of the older restaurants within the City do not have grease traps. Newer restaurants have been and will continue to require the installation of grease.traps; however, many of these grease traps are not properly maintained because of a lack of proper monitoring. Grease buildup problems occur most often in the side sewers. However, some grease buildup problems also occur in the sanitary sewer collection system. When problems do occur, 5-5 CHAPTER FIVE the City maintenance crews are usually called out to investigate. The City will need to allocate additional maintenance hours for monitoring this problem. Ultimately, a proper monitoring program should reduce maintenance time involved in removing grease buildup. Preventive maintenance should involve the installation of grease traps in all restaurant and food processing type facilities and proper maintenance of those grease traps. An ordinance should be prepared requiring owners of grease traps to write a letter, on an annual basis, certifying that proper inspection and maintenance have been performed. Certification should require a small fee to cover administrative costs. Fines should be imposed for certification fraud of improper inspection and maintenance practices. In addition, cost of cleanup due to problems associated with improperly maintained grease traps should be assessed to property owners. 4. EARTHQUAKE PREPAREDNESS The Seismotectonic Map of the Puget Sound Region (Gower and others, 1985) shows two significant faults and three small faults less than 10 miles from Renton City Hall. These faults are zones of weakness in the bedrock that could possibly be the sites of future earthquakes. The largest fault lies north of Renton; it is inferred on the basis of an abrupt change in relief (an escarpment) in the bedrock topography of the Puget Lowland. Many small earthquakes (<3.5 on the Richter Scale) have been detected along this escarpment,_especially beneath Seattle and Mercer Island where the depth to bedrock is deepest. The escarpment has an east-west trend which is perpendicular to the regional,north-south structural trend of the Puget-Willamette trough and the Cascade range. Because the basin in the bedrock north of this escarpment is filled with sediments, it is not expressed at the surface from Winslow to Mercer Island. However, east of Mercer Island, where it closely parallels I-90, it is marked by the high relief of the Newcastle Hills, Squak Mountain and Tiger Mountain. The middle to lower Tertiary rocks comprising those hills, and possibly upper Tertiary sediments (Walsh, personal communication, 1990) are strongly folded. Despite the seismic record of numerous earthquakes along the escarpment, no rupture or deformation of the ground surface appears to have occurred during the last 15,000 years. Another major fault that passes through Renton may begin in Bremerton and extend to Issaquah or connect with the well defined Hobart fault east-south-east of Renton. This fault is locally well expressed in lower to middle Tertiary rocks, but it does not deform Vashon glaciation and younger sediments (<15,000 year old). Furthermore, because historical earthquakes are not concentrated along its trend, this zone of weakness in the bedrock does not appear to be hazard. - Similarly, smaller faults west of Renton in Tukwila and through the South Center area, cut only the bedrock and do not appear to have been active for at least 15,000 years. Although direct rupture of the ground surface due to a major earthquake originating in the Renton area is unlikely, ground shaking and failure resulting from a regional magnitude 6.5 to magnitude 5-6 System Analysis and Conclusions 7.5 earthquake is likely during this decade. The recurrence interval for deep earth quakes (>40 km deep) of this magnitude is about 25 years in the Puget Lowland. Because so many earthquakes have occurred during the 14,000 years since the glacially sculpted • landscape emerged from beneath the melting ice, most features and sediments are adjusted to the ground motion of magnitude 7 or an even larger event. However,-steep slopes that have been undercut by rivers, man or the natural weathering and sapping processes of migrating groundwater, will be susceptible to failure. Particularly likely to fail (liquefy or slump) are areas of recent fill like the Cedar River delta and man-made deposits of insufficiently compacted saturated sandy to silty soils. In general, structures close to bedrock will be less impacted by ground motion than those on unconsolidated sediments or man-made fill. However, the topography of the bedrock surface beneath Renton will have a major influence on the focusing or attenuation of seismic energy. Areas overlying old valleys or basins in the bedrock, where fill may be hundreds of feet deep, may receive up to ten times.the shaking that neighboring bedrock hillsides will experience (Then and Hadley, 1986). Thus, facilities designed for the Duwamish valley and Maplewood area will have to meet higher standards of seismic design. Water,and sewer systems of the Renton area will very likely experience the significant ground motion associated with about a magnitude 7 earthquake during the 1990s. Because Renton has developed both on bedrock and deep fills of unconsolidated sediments, seismic energy will be locally focused, and verydifferent degrees of ground motion will be experienced by different parts of the system. Lift stations should be located as close to bedrock as possible, and the system should be designed to accommodate significant changes in seismic stress over relatively short distances (tenths of a mile). C. WASTEWATER COLLECTION BASINS The following section of this chapter presents an analysis of wastewater collection basins, which is presented in an order based on the seriousness of each basin's deficiencies. See FIGURE 1 for a location of basins. A brief summary of those deficiencies follows. • The wastewater within the May Creek Basin is currently diverted into the Lake Washington East Basin causing an overload of that system. The construction of the May Valley Interceptor is necessary to correct these problems. • In the Lower Cedar River Basin, a moratorium on development is in place because the sewer pipe lines are currently over capacity. 5-7 CHAPTER FIVE • • Lake Washington East Basin currently receives wastewater from the Sunset Lift Station which significantly contributes to overloading the North Highlands • Interceptor. • The Panther Creek subbasin in the Black River Basin is at or near capacity; the Renton Industrial Subbasin is experiencing increasing demands as a result of land use changes. • In the Lake Washington West Basin, the West Renton subbasin has sections of sewer lines that experience some capacity problems. • The Duwamish Estuary Basin is for the most part undeveloped and is not experiencing capacity problems at this time. 1. MAY CREEK BASIN • The May Creek Basin is located in the northeast part of the City. Most of this basin is currently unsewered and is located on the periphery of the City's current service boundary. The May Creek Basin is jointly served with King County Water District No. 107. The City serves approximately 910 acres of this basin which consists of primarily single-family and light commercial land uses. The ultimate sewerage of the May Creek Basin will be through the extension and completion of the proposed May Valley Interceptor (whether by METRO, the City or King County Water District No. 107). At this time, there are three lift stations serving low lying areas along Lake Washington in this basin. These are the Misty Cove, Baxter and Denny's Lift Stations. The City is experiencing development pressure within the May Creek Basin and the Honey Creek Subbasin,which requires immediate attention be given to the sanitary sewer facilities in this area. The primary concern is the Devil's Elbow Lift Station. This lift station was designed and constructed in 1985 to accommodate existing development. In addition, the Devil's Elbow Lift Station has experienced operational problems and the force main is structurally unreliable due to soil movement along NE 27th Street. The City is attempting to accelerate the construction of the May Valley Interceptor with the assistance of King County Water District No. 107. The May Valley Interceptor would eliminate the need for the Devil's Elbow and Sunset Lift Stations. Elimination of these lift stations would also eliminate many of the capacity problems within the Kennydale and North Renton Subbasins. However, completion of this interceptor, along with Phase IV of the Honey Creek Interceptor, is not expected until 1993 at the earliest. 5-8 System Analysis and Conclusions Interim improvements to the Devil's Elbow Lift Station should be studied. These interim improvements could be completed in 1991 and would increase the reliability and possibly the capacity of the Devil's Elbow facilities. HONEY CREEK SUBBASIN The May Creek Basin includes the Honey Creek Subbasin, which is currently served by the Sunset, Summer Wind and Devil's Elbow Lift Stations. These lift stations currently pump wastewater collected in the Honey Creek Subbasin to the Lake Washington Basin East. They will be removed from service after completion of the May Valley Interceptor and the Honey Creek Interceptor. This is a large subbasin serving approximately 430 acres of the city. The sewage is routed to Sunset Lift Station where it is pumped to the North Highlands Subbasin. A serious capacity problem exists in this subbasin within the interceptor along Sunset Avenue east of.Union Avenue. The sanitary sewers within the Honey Creek Subbasin are designed to direct 95 percent of the wastewater toward the Sunset Lift Station. This results in excessive overloading of this lift station. On many occasions the Sunset Lift Station is required to operate both pumps continuously for several days, which is an undesirable operating condition. In addition, wastewater discharged from this lift station adversely impacts gravity sewers in the North Highlands Subbasin. If the sunset lift station cannot pump all of the incoming flow, the wastewater is automatically discharged through an overflow device to the Honey Creek Interceptor and is then pumped to the Kennydale Subbasin through the Devil's Elbow Lift Stations. During peak storm events, wastewater flow rates have been know to exceed the capacity of both the Sunset and Devil's Elbow Lift Stations, resulting in raw sewage overflows into Honey Creek. Marge potential for development exists, within this subbasin, and the correspondingly higher flows will create more extensive capacity constraints in the future. A more detailed description of the capacity problems of the Devil's Elbow Lift Station can be found in the lift station section of this chapter. As reported in the 1983 Comprehensive Sewer Plan, sanitary sewers within the Honey Creek Subbasin exhibit substantial amounts of infiltration and inflow, which results in • excessive loading of the Sunset Lift Station and periodic overflows into Honey Creek. In an attempt to reduce the amount of infiltration and inflow;within this subbasin, the City contracted with Gelco Grouting Service to examine and correct infiltration and inflow problems within this basin. The work was separated into three phases under project Nos. S-370(1983), S-379(1985), and S-421(1986). In addition, the City also constructed the Honey Creek Interceptor, which is currently designed to receive the wastewater from the Honey Creek Subbasin that cannot be handled by the Sunset Lift Station. 5-9 • CHAPTER FIVE 2. LOWER CEDAR RIVER BASIN The Lower Cedar River Basin includes the eastern portion of the City of Renton bordering the Cedar River. The City serves approximately 2610 acres at this basin which consists of primarily single-family and multi-family developments with some commercial and light industrial land uses. This basin includes the Central Renton, South Highlands, Maplewood, Heather Downs, East Maplewood, and Tiffany Park Subbasins. Due to extensive development and annexation pressures within this basin, an engineering investigation of the sanitary sewer system in the South Highlands, Maplewood and Heather Downs Subbasins was performed in the spring of 1989 by RH2 Engineering. The results of this study are present in a report entitled An Engineering Investigation of Sanitary Sewer Facility Improvements for the East Renton, Heather Downs, and South Highlands Areas. These results indicated inadequate sanitary sewer capacity in the South Highlands and Heather Downs Subbasins, and limited available capacity in the Maplewood Subbasin. As a result of this engineering investigation, the City Council passed Resolution No. 2764, which established a moratorium on the connection of new construction to any of the existing sanitary sewers in the South Highlands, and Maplewood or Heather Downs Subbasins. The moratorium will be in effect until January 31, 1992, unless extended by the City Council. The City is currently working on the environmental study and predesign alternatives for the proposed East Renton Interceptor which would solve the sanitary sewer capacity problem. CENTRAL RENTON SUBBASIN. The Central Renton Subbasin includes the central business district of the City located north of the Cedar River and south of North 3rd Street. Many of the sewers in this subbasin are old and some have experienced structural failure. This area is within Zone 1 of the Aquifer Protection area, and exfiltration from these sewers could contaminate the City's drinking water supply. This area consists primarily of residential and commercial land uses. SOUTH HIGHLANDS SUBBASIN The South Highlands Subbasin is located south of NE 7th Street and north of NE 4th Street in the Highlands area. Land use in this subbasin consists primarily of single-family residential developments. This is a large subbasin serving approximately 600 acres. It connects into the METRO Interceptor at North 4th Street and Logan Avenue North. Two lift stations pump into this basin: Honeydew and Union 600. As a result of development pressures within this 5-10 System Analysis and Conclusions subbasin, an engineering investigation on the sanitary sewer system was performed in 1990 by RH2 Engineering. The results of this study are presented in a report entitled An Engineering Investigation of Facility Improvements for the South Highlands Sanitary • - Sewer Basin. The major problem it identified is an inadequately sized interceptor, which the report presented options for correcting. The capacity created through the East Renton project will benefit this basin. MAPLEWOOD SUBBASIN The Maplewood Subbasin is located primarily south of NE 4th Street. This area serves a variety of land uses including single-family and multi-family residential as well as some commercial and light industrial land uses. This subbasin receives wastewater pumped from the Union 600 Lift Station. This subbasin connects into the METRO Cedar River Interceptor along the Maple Valley Highway. This subbasin has adequate sewer capacity for existing development. However, future development will require either the construction of additional sewer capacity or the reduction of existing wastewater flows such as the elimination of the Union 600 Lift Station. HEATHER DOWNS SUBBASIN The Heather Downs Subbasin is located along the eastern border of the City Limits. This subbasin consists primarily of single-family residential development with some multi- family developments in the northern portion of this subbasin. Several capacity problems currently exist within this subbasin. The City is currently developing solutions through the East Renton Interceptor project whichwould alleviate the sewer capacity problems. This project is in the predesign and environmental review stage. In addition to the capacity problems in the Heather Downs Subbasin, a section of the Heather Downs Interceptor was constructed on a very steep slope (approximately 65% - slope). The sewer section in question is located along a power line easement near the plat of Maplewood. It was constructed using.10-inch PVC sewer pipe with concrete collars to stabilize the pipe on the steep slope. No indication of potential structural failure exists. However, a study should be conducted to determine the integrity of the sanitary sewer. The City should video inspect this sewer to examine the internal integrity and to locate any pipe or manhole movement. If a 5-11 CHAPTER FIVE problem is found, a geotechnical consultant could examine the steep slope for stability and the potential of soil shifting. This information will help determine the need for construction of an interceptor in a new alignment. EAST MAPLEWOOD SUBBASIN The majority of the East Maplewood Subbasin is located outside the City limits. Currently a majority of this basin is unsewered. The small portion that is sewered is being pumped to the South Highlands Subbasin through the Honeydew Lift Station. With recent development in this area, the City is currently studying the construction of an interceptor in this subbasin to serve areas within the City through the East Renton Interceptor Project. TIFFANY PARK SUBBASIN The Tiffany Park Subbasin is located on the south side of Cedar River. This subbasin includes primarily single-family and multi-family developments. This subbasin includes two lift stations: the Falcon Ridge Lift Station and the Cottonwood Lift Station. In addition, this subbasin receives wastewater from the Soos Creek Water and Sewer District. The Tiffany Park Interceptor is a joint use facility between the City of Renton and the Soos Creek Water and Sewer District (formerly Cascade Sewer District). The gravity interceptor is currently not experiencing capacity problems, but there is evidence that peak, wastewater flows exceed the design capacity of METRO's inverted siphon crossing the Cedar River. METRO is considering replacing the inverted siphon with a new gravity sewer which would be sized to accommodate these peak flows. This new METRO sewer would be located on a bridge over the Cedar River that could be used for a proposed trail. • The majority of the wastewater in this interceptor originates in the Soos Creek system, includingSoos Creeks Lift Station No. 5. Accordingto the Soos Creek Comprehensive P Sewer Plan, Lift Station No. 5 is considered to be a permanent facility which serves a large basin. As development of this basin proceeds, increased pumping from the lift station will aggravate capacity problems in METRO's inverted siphon and increase the potential for wastewater release to the Cedar River. 3. LAKE WASHINGTON EAST BASIN The Lake Washington East Basin is located in the northern part of the City and includes the Kennydale, North Highlands and North Renton areas of the City. The City serves this entire basin of 2100 acres which consists of a variety of land uses including single-family and multi- 5-12 System Analysis and Conclusions family residential, light commercial and heavy industrial activities. This basin is divided into four subbasins which collect wastewater and transport it to METRO's East Side Interceptor. - KENNYDALE LAKEFRONT SUBBASIN The Kennydale Lakefront is the northernmost subbasin in the Lake Washington East Basin. This subbasin serves primarily residential communities and includes the Lake Washington Flush Station and Lake Washington Lift Station No. 2, which serve the residential community adjacent to Lake Washington (Coleman Point). This is a medium size subbasin of approximately 110 acres which has almost reached saturation development. This subbasin connects into the METRO Interceptor at N. 38th Street and Lake Washington Boulevard. The Kennydale Lakefront sanitary sewer collection system is a low-pressure, force main. Water from Lake Washington is pumped periodically into the force main through Lake Washington flush station. Lake water and the sewage is discharged from this low- pressure force main into the Lake Washington No. 2 Lift Station, where it is then pumped into the METRO East Side Interceptor. The original force main was installed in 1960 and has a history of various problems and requires considerable maintenance. In 1986 the City attempted to improve the collection system through the installation of additional cleanouts on the low-pressure force main and the installation of plug valves on each of the individual side sewers, which could be closed during cleaning operations. This work was conducted under project No. S-442. Upon completion of the additions to the force main and side sewers, the City attempted to clean the low-pressure force main using a sewer pig. Even though the side-sewer,plug valves were closed, two homes were flooded out with backed-up wastewater. Since 1986 no further attempts have been made to thoroughly clean the low-pressure, force main. Since this part of the sewer system continues to require high maintenance, the City should continue examining alternatives, that could reduce some of the maintenance and provide a more reliable and efficient system. KENNYDALE SUBBASIN The Kennydale Subbasin serves primarily residential communities including both single- family and multi-family developments. The eastern portion of this subbasin is mostly unsewered at this time. The City has received verbal indication from the King County Health Department of random septic system failures in this area. While the extent of these failures is not known, there is no indication of area or basin-wide problems, but rather localized problems. This subbasin includes two lift stations: the Highgate Lift 5-13 CHAPTER FIVE Station and the Azalea Lane Lift Station. In addition, the Devil's Elbow Lift Station pumps wastewater from the Honey Creek Subbasin to the Kennydale Subbasin. This basin serves approximately 200 acres of the City of Renton, where, there is potential for future development and hence higher flow rates. This subbasin was modelled as if the Devil's Elbow and Azalea Lane lift stations were on-line and were pumping simultaneously. The subbasin connects into the METRO East side Interceptor at Lake Washington Boulevard, south of 28th Street. NORTH HIGHLANDS SUBBASIN The North Highlands Subbasin serves a large area of both residential and commercial developments. A major portion of the sanitary sewer system in the North Highlands Subbasin was constructed during World War II. These older sewer systems are near the end of their useful life and require increased maintenance. The Sunset Lift Station pumps sewage from the Honey Creek Subbasin to the North Highlands Subbasin. The North Highlands Interceptor beginning at NE 7th Street and continuing along Sunset Boulevard (approximately 7,200 lineal feet) currently exceeds design capacity. This is primarily a result of receiving wastewater from the Sunset Lift Station. The City's CIP currently has funds targeted for replacing the interceptor, which will increase the capacity of the lower portion of this interceptor. Since wastewater pumped from the Sunset Lift Station is a major factor contributing to capacity problems in the North Highlands Interceptor, additional efforts should focus on constructing the May Valley Interceptor which would provide gravity sewer service to the Honey Creek Subbasin. However, until the May Valley Interceptor is constructed and the Sunset Lift Station is removed from service, the current configuration provides. the best solution. NORTH RENTON SUBBASIN The North Renton Subbasin is located on the south end of Lake Washington between the Cedar River and Interstate 405. This subbasin consists of commercial and heavy industrial land uses and includes two lift.stations: the Boeing Lift Station and the Lake Washington Beach Lift Station. The North Highlands/North Renton Subbasin serves approximately 600 acres in the City of Renton. Many sections of this basin were not modelled due to a lack of physical data. Severe capacity problems exist within the interceptor along N 6th Street as a direct result of receiving wastewater from the Sunset and Boeing Lift Station. The Boeing Lift Station • 5-14 • System Analysis and Conclusions is planned to be eliminated through the construction of the Park Avenue Interceptor. This subbasin connects into the METRO Interceptor at N 6th Street and Logan Avenue N. 4. - BLACK RIVER BASIN • The Black River Basin is a large drainage basin in the southwest part of the City and includes the South Renton, Rolling Hills, Talbot Hill, Renton Industrial, Panther Creek, and Springbrook Subbasins. The higher elevations in the Rolling Hills, Talbot Hill, and Panther Creek areas are generally single-family and multi-family residential developments, while the valley floor is generally for industry and commercial land uses. The City serves approximately 3170 acres of this basin. SOUTH RENTON SUBBASIN • The South Renton Subbasin includes the commercial business district south of the Cedar River and the residential communities located on the lower slopes of the Rolling Hills. Currently no lift stations are located in this subbasin. Most of the sanitary sewers are in adequate condition and have sufficient capacity for this subbasin; however, older sewers do exist, but are not known to cause problems at this time. Some sewers will need to be relocated as a result of construction on I-405. This will be performed by the Washington State Department of Transportation. ROLLING HILLS/TALBOT HILL/PANTHER CREEK/SPRINGBROOK SUBBASIN The Rolling Hills, Talbot Hill, Panther Creek and Springbrook Subbasin serves the residential communities in the southeast area of the City. This subbasin serves primarily single-family and multi-family communities. The Talbot •Hill Subbasin includes the Talbot Crest Lift Station. An agreement is currently being negotiated between Soos Creek Water and Sewer District and the City which will define service area boundaries and result in joint use of the Springbrook Interceptor which serves the Springbrook Subbasin. The Talbot Road interceptor which serves a majority of the Panther Creek Subbasin is undersized to service this area. Thisinterceptor should be replaced with larger pipe. RENTON INDUSTRIAL SUBBASIN • The Renton Industrial Subbasin includes the area south of Interstate 405 and west of the East Valley Freeway. This area is also called the Orillia Industrial District. This subbasin includes the Lind Avenue and East Valley Lift Stations. Many areas within the subbasin are only sparsely developed at this time. This area was originally developed for 5-15 1 CHAPTER FIVE light industry and warehousing; however,in recent years the land use has changed rapidly. Increasingly, warehouse type buildings are being converted to office parks, which places increased demands on the existing sewer systems. Consequently, the City should - periodically re-examine wastewater flow rates in order to better evaluate sanitary sewer needs. 5. LAKE WASHINGTON WEST BASIN The Lake Washington West Basin is located in the northwest part of the City. The basin is bordered to the east by the Cedar River and to the south by Sunset Boulevard West. The City serves approximately 710 acres within this basin which consists of primarily single-family and light commercial land uses. This basin primarily transports wastewater to the east into the METRO East Side Interceptor. This basin comprises two subbasins: the West Hill Subbasin and the West Renton Subbasin. Also included in this basin is a portion of the Bryn Mawr-Lakeridge Water and Sewer District and Skyway Water and Sewer District. • WEST HILL SUBBASIN The West Hill Subbasin serves the residential communities on the West Hill north of Renton Avenue South. The subbasin includes the Airport Lift Station located at the City of Renton Airport. This is a large subbasin serving approximately 350 acres. Potential for additional development within the City limits in this subbasin is minimal. Some areas were not modelled in this subbasin due to a lack of physical data. Data which is available is suspect, due to extensive sewer reconstruction, rehabilitation, and the age of the sewers. The sewer system which was modeled appears to have sufficient sewer capacity. WEST RENTON SUBBASIN The West Renton Subbasin serves residential communities west of Rainier Avenue South and the commercial district east of Rainier Avenue South. This subbasin includes the Sears Lift Station and the Earlington School Lift Station. The West Renton Interceptor located in the West Renton Subbasin is experiencing capacity problems along Renton Avenue S.These capacity problems are primarily a result of undersized sanitary sewers, which are serving a large area. Wastewater flows from the Sears and Earlington School Lift Stations are also adversely impacting this interceptor 5-16 _ - System Analysis and Conclusions The existing interceptor is approximately 3,700 lineal feet of 12-inch and 15-inch sanitary sewer. The City should examine the possibility of increasing the size of this interceptor or providing additional interceptors in this basin. Many sewers are also very old and require replacement, such as the gravity sewers along S. 4th Street. 6. DUWAMISH ESTUARY BASIN The Duwamish Estuary Basin islocated in the western portion of the City and includes the immediate area surrounding METRO's Renton Treatment Facility. This basin also includes a portion of the Skyway Water and Sewer District. The City serves approximately 580 acres within this basin which primarily consists of light industrial land uses on the valley floor and residential developments on the hillsides. There are no sewer capacity problems which have been identified within this basin. D. LIFT STATIONS This plan evaluated lift stations against the standards and guidelines for construction of sewage lift stations that are detailed in Chapter 3 of the "Criteria for Sewage Works Design" manual prepared by the Washington State Department of Ecology. This chapter includes design standards and guidelines for lift station location, pump sizing and selection, wet well sizing criteria, alarm system, emergency response criteria, force main criteria, lighting and ventilation. These standards and guidelines have been established to ensure protection of the environment and property through design and operation of reliable sewage lift stations. The City of Renton has 23 sewage lift stations, which are shown and inventoried in FIGURE 3. Each station was inspected for safety and accessibility, and operation and maintenance manuals for each were reviewed at the City Shops. The results of these inspections are presented in the following paragraphs, and the lift station inventory summaries are presented in TABLE V-1. Detailed Lift Station Data Sheets are provided in Appendix A. With few exceptions, these lift stations have no major inadequacies in terms of safety or reliability: Most of the lift stations have tone-generated telemetry to the City Shops which activate alarms for high and low wet-well levels, power failure, signal loss and, in some stations, intrusion alarms. LIFT STATION NO. 1 - AIRPORT The Airport Lift Station is located on the east side of West Perimeter Road within the airport property. This facility is a fiberglass, wet well mounted, duplex lift station with a duplex vacuum priming system. This facility serves the airport facility along West 5-17 1.

The lift station is in good condition and has proven to be reliable. An emergency power connection should be installed at this facility. - LIFT STATION NO. 2 - AZALEA LANE The Azalea Lane Lift Station is located on the east side of Aberdeen Ave NE, south of NE 24th St. This facility is a fiberglass, wet well mounted, duplex lift station with a duplex vacuum priming system and serves the communities east of the lift station. The lift station is in good condition and has proven to be reliable although it experiences periodic flooding. An overflow pipe connects the storm sewer system to the lift station wet well. As a result, during peak storm events the lift station is required to pump both wastewater and stormwater. The City will examine stormwater problems in this area as part of the Comprehensive Storm and Surface Water Management Plan. One alternative being considered is to construct a stormwater interceptor to serve this area. This lift station will be taken off-line and removed when wastewater from this area is diverted by gravity through the future East Kennydale Interceptor. LIFT STATION NO. 3 - BAXTER The Baxter Lift Station is located in the J.H. Baxter and Co. pole yard near NE 44th Street adjacent to the railroad tracks. This facility is a ;recessed, wet well mounted, duplex lift station with a duplex vacuum priming system. The station serves the mill, owned by the LH. Baxter and Company, and the community along the lake north of NE 44th Street. The lift station is in good condition and has proven to be reliable. There is a creosote smell in the lift station originating from wastewater generated at the mill. .Access to this facility is through the pole yard and is made difficult during rainy periods. LIFT STATION NO. 4 - BOEING . ' The Boeing Lift Station is located on the northeast corner of N. 8th Street and Park Avenue N. This facility is a duplex, wet well/dry well lift station and serves the Boeing facilities adjacent the lift station. The lift station is in generally good condition but has poor access and requires a hoist to remove the manhole cover for access. This lift station will be eliminated by constructing a gravity sewer north along Park Avenue N. to METRO's East Side Interceptor in conjunction with the reconstruction of this street. • LIFT STATION NO. 5 - COTTONWOOD The Cottonwood Lift Station is located west of the Riviera Apartments, south of the Maple Valley Highway. This facility is a recessed, wet well mounted, duplex lift station. This facility serves the area between the Maple Valley Highway and the Cedar River,east of the Stoneway concrete facilities. The lift station is dangerous and needs to be replaced. The coatings of the mechanical equipment and dry-well walls are in poor 5-19 CHAPTER FIVE condition. The wet well has an overflow bypass to the Cedar River. However, during high river stages, river water can flow into the wet well. As a result, a valve has been installed on the bypass and is manually closed by, operation and maintenance personnel during periods of expected, high river levels. LIFT STATION NO. 6 - DENNY'S The Denny's Lift Station is located on the east side of Lake Washington Boulevard next to the Denny's restaurant. This facility is a fiberglass, wet well mounted, duplex lift station with a duplex vacuum priming system. This facility serves the Denny's restaurant, is in good condition and has proven to be reliable; however, mechanical equipment needs to be repainted. The lift station does experience some problems due to grease discharges from the restaurant and flooding during peak storm events. LIFT STATION NO. 7 - DEVIL'S ELBOW The Devil's Elbow Lift Station is located at the unimproved intersection of NE 27th Street and 120th Place SE adjacent to Honey Creek. This facility is a wet well mounted, duplex lift station with a duplex vacuum priming system which is housed in a fiberglass building. The lift station is in fair condition, but is susceptible to vandalism, even though the site has a chain-link fence because of its remote location. Pumps have had problems holding their prime and the mechanical equipment needs to be repainted. A portion of the force main needs to be replaced due to soil creep along NE 27th Street. This lift station will be taken off-line and removed when the Honey Creek Interceptor and May Valley Interceptor are completed. The Devil's Elbow lift station was designed in conjunction with the Honey Creek Interceptor in 1986. According to the Engineering Report, the lift station was intended to be an interim facility until the May Valley Interceptor was constructed. The Honey Creek Interceptor was designed to meet saturation flow conditions from the Honey Creek Basin. However, according to the engineering report, the Devil's Elbows Lift Station was designed to meet existing conditions and not to provide a long-term solution for this subbasin. Each pump within the Devil's Elbow lift station is designed for 450 gallons per minute. The Devil's Elbow Lift Station pumps into the Kennydale Subbasin near the intersection of Edmonds Avenue N.E. and N.E. 27th Street. It was determined that wastewater discharged from this lift station would adversely impact the gravity sewers in the Kennydale Subbasin. For this reason, all sewers that were adversely impacted were up- sized in order to handle this additional 450 gallons per minute. In addition a lock-out was 5-20 . System Analysis and Conclusions put on the Devil's Elbow Lift Station so that both lift station pumps would not pump simultaneously. In recent years, the configuration within the Honey Creek Subbasin has become increasingly problematic. The Devil's Elbow Lift Station was designed to alleviate capacity problems which existed in 1986; increased development within this subbasin has resulted in higher peak wastewater flow rates, causing additional stress to both the Sunset and Devil's Elbow Lift Stations. During peak storm events, wastewater at the Devil's Elbow lift station has overflowed into Honey Creek. The pump lock out at Devil's Elbow Lift Station is an additional problem. If a pump within this facility was signaled to operate but could not because of a malfunction, the pump lock-out would prevent the second pump from taking over. The City maintenance crews can only find out about this problem after the high level alarm at the lift station has been activated. Before further development occurs in this subbasin, a study should be undertaken to determine alternative to improve system capacity within all of the facilities affected by this deficiency. LIFT STATION NO. 8 - EARLINGTON SCHOOL The Earlington School Lift Station is located on the southwest side of S. Langston Road between S. 132nd Street and S. 134th Street.

The lift station is in good condition but has poor access and is difficult to keep clean due to its location on the gravel shoulder. This lift station will be taken off-line and removed when wastewater from this area is diverted by gravity through the future Renton Avenue Interceptor. LIFT STATION NO. 9 - EAST VALLEY The East Valley Lift Station is located on the northwest corner of the intersection of SW 34th Street and the East Valley Road. This facility is a duplex wet well/dry well configuration with a single vacuum priming system. This facility serves the commercial areas north and west of the lift station. The lift station is in generally poor condition. The above-grade electrical enclosures have experienced vandalism, even though the site is enclosed in a chain-link fence. Lift station walls and mechanical equipment need to be repainted. The single vacuum priming system does not allow complete redundancy; this means that the lift station will not operate if there is a failure of the vacuum priming 5-21 CHAPTER FIVE system. Since this lift station is considered to be permanent, it is recommended that this lift station be rehabilitated to make it more reliable. - LIFT STATION NO. 10 - FALCON RIDGE The Falcon Ridge Lift Station is located at the east end of SE 8th Street in the plat of Falcon Ridge. This facility is a fiberglass enclosed, wet well mounted, duplex lift station with a duplex vacuum priming system, which is in good condition and has proven to be reliable.

However, Pump No. 1 is not operational. The lift station could be placed back into operation, if required. LIFT STATION NO. 13 - HONEYDEW • The Honeydew Lift Station is located in the middle of Union Avenue NE just north of • NE 7th Street. This facility utilizes two, non-clogging, submersible pumps. This facility serves the communities north of the Kiwanis Park and the Honey Dew School along Union Avenue NE. The lift station is in fair condition. However, because it is located in the middle of Union Avenue, traffic control must be set up to access the lift station. The lift station will be taken off-line and removed when the wastewater from this area. is directed by gravity through future developments to the east. These developments, i.e. The Orchards, should be required to plan for the diversion of wastewater from this lift 5-22 • System Analysis and Conclusions •station through the property. Honeydew Lift station cannot be taken off-line until the completion of the East Renton Interceptor. - LIFT STATION NO. 14 - LAKE WASHINGTON BEACH The Lake Washington Beach Lift Station is located in the parking lot at Coulon Beach Park. This facility is a duplex wet well/dry well lift station which serves the restroom facilities at the park. The lift station is in good condition.

PRIVATE LIFT STATIONS • There are also privately owned and maintained lift stations within the City's service area, which are: Lift Station Location Owner • Pelly Avenue North near North 7th Boeing Company • Rainier Avenue near NW 6th Airport Utility • • 148th Avenue SE opposite North 10th (Apollo School) King County Water District No. 90 • East of Kennydale Elementary Private Development • Puget Drive near Rolling Hills Private Development • Tukwila Lift Station near METRO plant City of Tukwila New private lift stations must meet city standards and be required to have a maintenance agreement with the City. This agreement would allow the city maintenance crews to service these private lift stations, at the owner's expense, when neglect has resulted in a health hazard. 5-25 CHAPTER FIVE E. TELEMETRY AND CONTROL SYSTEM Accurate information that details the flow rates in the collection system and trunk lines is paramount to successful system operation and planning. Most of the operation issues, and all of the planning elements, are driven by and based on the flow rates in the pipelines. Without accurate flow rate information, flow rate assumptions must be made based on population estimates and industry standard assumptions about per capita sewage contribution, and infiltration and inflow. The accuracyof an analysis based on these assumptions is no better than the accuracy of the assumptions. To illustrate the importance of accurate flow rate, the following planning and design issues that are directly based on flow rates was compiled: • The sizes of the pumps in each lift station are based on maximum flow rates in the influent sewer mains. • Collection system, trunk mains, and force mains are based on maximum flow rates from the-contributing areas. • Lift station wet well volumes are based on expected influent flow rates and projected emergency reaction times. • Pump run set points are based on providing maximum pump cycle times without allowing the stored sewage to become septic. These are based on influent and pumping flow rates. • The priority and schedule within which facilities are replaced is based on the flow rate capacity of the facility compared with the actual flow rate in the system. Facilities which are operating at or above capacity are replaced first, followed by facilities that are closest to maximum capacity. • : • • Actual system flow rates can be compared with the per capita contribution and pipe material and age to develop relationships between flow rate and population density. Without these relationships, large safety factors must be added to industry standard ratios for per capita flow rates. These, unnecessarily, increase costs or limit development. Without these system-specific ratios, it is also impossible to accurately predict overloaded facilities before the overload shows as surcharged manholes or overflowing wet wells. Renton's existing sanitary sewer system operates without accurate flow rate information and without adequate maintenance management information. The flow rate data used to develop and calibrate the system-wide computer model was based on industry standards for per-capita flow and land use designations. Although we believe these values are conservative, it is impossible to identify to what extent they are above actual system flow rates. Undoubtedly, they are more conservative in some areas than in others. This lack of real and accurate data has diminished the 5-26 System Analysis and Conclusions ability to identify all potential problem areas, and to develop the most efficient and most cost effective capital improvement program. To date, the operating staff has reacted to system emergencies as they occur, rather than preventing emergencies through an organized, adequate maintenance schedule. To the credit of the maintenance staff, they have performed well with the information available. It would be impossible to improve the maintenance program without additional maintenance management and flow rate information. A properly designed and maintained telemetry and control system includes the following features: Alarm Abnormal Events • Provide Engineering Information • Provide Maintenance.Information React to System Emergencies Reduce Operating Costs Provide a Convenient Storage Media Schedule Maintenance Tasks Improve Safety Each of these features is discussed in detail below. ALARM ABNORMAL EVENTS Although most sanitary sewer telemetry systems include some alarm information, the following alarms are required for the system to provide the maintenance information necessary to optimize system operation. • High wet well level Low wet well level Pump fail (each pump) Low pump flow rate •Power fail • Fire alarm • Telemetry fail Hazardous gas detection . Water in the dry well Personnel panic alarm Intrusion alarm •. 5-27 CHAPTER FIVE EMERGENCY INFORMATION Emergency information necessary from the telemetry system must include the influent - flow rate to each lift station. This is a calculated quantity based on the length of time it takes to fill a known volume in the wet well. The influent flow rate should be reported ' as a maximum, minimum, and average value. Pump flow rate is provided by installing an electro-magnetic flowmeter on the discharge side of the pumps. Although doppler ultra-sonic meters are commonly used for this purpose, their reliability and calibration are not capable of providing the precise information necessary. Since each pump discharges through the same flowmeter on alternating cycles, the flow rate difference (difference in pump output) can be used to alarm a pump that is partially plugged or that has worn significantly. The alarm features and flow rate capability of the telemetry system can also be used to identify facilities with a higher than average failure history and to calculate and optimize pump start and stop set points. Pump set points should be calculated to maximize the interval between pump starts, while still maintaining adequate storage . reserves in the wet well. These levels should be allowed to automatically change throughout the day to optimize pump run times. In addition, the telemetry system should track and store flow rate trends to be used for engineering and planning purposes. MAINTENANCE INFORMATION The telemetry system must automatically track and display pump efficiency at each lift station. This is accomplished by measuring flow rate and electrical current and calculating the efficiency of each pump cycle. The maintenance staff uses pump efficiency to identify pumps that are near the end of their service life and need to be replaced, or pumps that are plugged or partly plugged and need service attention. In addition, the system should continuously monitor,calculate and-- display the high level response time at each wet well in the system. The response time continuously varies depending on the influent rate and the volume above the alarm level in the wet well, and it is useful in determining the sequence of reactions to multiple high level alarms. During a multiple alarm episode, the staff can respond to the wet well with the shortest, high level response time. The failure history of each lift station should be monitored to identify recurring problems or chronic failure sites. This information is then used to identify frequency of maintenance per site and when facility replacement is due. REACT TO SYSTEM EMERGENCIES The telemetry system should be configured to automatically react to some system emergencies. For example, lift stations in series should be locked out if a receiving lift station has a high level alarm. If an overflow is unavoidable, the station that causes the 5-28 ; I CHAPTER FIVE SCHEDULE MAINTENANCE TASKS Any telemetry system should be compatible with the City's existing maintenance management system, and the database should be configured to provide real-time operating information to the maintenance system. Pump maintenance should be based on the total running time of each pump and the number of starts of each pump. This information is available through the telemetry system. Each lift station and each pump combination has its own characteristic maintenance requirements. Some pumps may require maintenance every 1,000 hours others every 15,000, hours depending on the service and duty conditions in each facility. Real time operating information can provide the maintenance system with the proper data to develop the necessary maintenance requirements at each site. This procedure results in the most efficient use of the maintenance staff's time and reduces overall operating costs. In addition, it.eliminates the most frequent sources of equipment failures. IMPROVE SITE SAFETY The telemetry system should continuously monitor for hazardous gases in the dry well and alert operating personnel of unsafe conditions. A personnel panic alarm at each site should be used for added operator safety. .A.central reporting of the occupied lift stations allows the maintenance managers to locate and track the maintenance crews for added. safety and reliability. 1. EXISTING TELEMETRY SYSTEM The City currently owns and operates an analog, signal-based alarm reporting system, manufactured by Stead & Baggerly of Bellevue, Washington, which monitors each lift station. The system includes a master console that is located in the City Shops, and a remote telemetry transmitter located in each lift station. The master console is in continuous contact with most lift stations via dedicated telephone wires and circuits. Telemetry tone transmitters in each lift station report the operating status of the lift station pumps and alarm events. The following data is telemetered and displayed at the Master Console: Component Status Pump 1 Run Pump 2 Run Wet Well High Level Alarm Station Power Fail 5-30 System Analysis and Conclusions Alarm conditions are transmitted to on-call maintenance personnel using automatic telephone dialer. - Although this system has operated reliably, it does not generate the information necessary to optimize operation of the lift station facilities and the collection system. The leased telephones are expensive and are not regularly maintained by the telephone company. The existing system is not easy to troubleshoot or repair, and must be maintained by an independent contractor. The current system does not measure or record flow rate, includes no redundancy, has no data logging, no maintenance management information, and no control capability. • 2. PROPOSED SYSTEM IMPROVEMENTS The Renton Sanitary Sewer System needs a new comprehensive Telemetry and Data Logging !, System. The system should be used by the engineering staff to verify or modify the flow rate assumptions made in this plan and to identify additional improvements necessary. The maintenance staff will use the system to reduce costs, improve reliability and increase safety. The new system must be digital, signal-based, using a high security, binary coded decimal for Telemetry transmission. The system should run on IBM compatible computers and use smart remote telemetry units at the lift stations and collection system monitoring points. Telemetry should be a combination of leased telephone line and radio transmission, with the radios being the preferred transmission media. Because the lift stations are often located at the bottom of drainage basins, radios may not work at all sites. These sites should use leased telephone lines for data transmission instead of radios. Control of the facilities should be accomplished in a distributed format, wherein the control computer provides pump run set points that are based on optimal,pump operating conditions, and also locks out various lift stations during high-level alarms from various downstream lift stations. All other control is initiated from the Remote Telemetry Unit, including pump start/stop from the level transducer, back-up pump control from the float switches and station alarms. The system should use strain-gauge, level transducers that are suspended in the wet well for primary pump control, and use float switches for back-up pump control in the event of transducer failure. Pump discharge flow rates should be measured using an electro-magnetic flowmeter. Influent flow rates do not need to be measured directly, but rather can be mathematically synthesized by measuring the time it takes to fill a known volume of the wet well. 1 The engineering and system status information that is presented at the City Shops should also be displayed in real time format at City Hall using a networked data logger computer. This will allow the engineering and planning staff access to system information without disrupting the maintenance staff. 5-31 CHAPTER FIVE The computer and data storage system should be compatible with the existing water data logger • to provide redundant data storage and to provide hot standby fail over controllers. The system . should also be integrated with the existing maintenance management system to provide real time operating data and failure history data to the maintenance system. Each remote telemetry unit,located in each lift station, should include intelligent telephone dialer alarm systems, so that critical alarms can be relayed to on-duty maintenance personnel, even . during a telemetry system failure. Telemetry and control should be provided at each lift station in the system, and at strategically located, collection system flow-metering points. A pre-design report should be developed in conjunction with the telemetry system replacement design to identify the number and location of flow metering stations. F. WASTEWATER QUALITY • The quality of wastewater transported in the Renton sanitary sewer system varies considerably depending on the wastewater source, detention time within the sanitary sewer system and the volume of infiltration and inflow. This chapter discusses several aspects of wastewater quality and will recommend measures to control or eliminate wastewater quality problems. 1. DOMESTIC WASTEWATER . The quality of domestic wastewater varies and is a direct result of the type of water used within the home. Some domestic sewage can be considered stronger than others. One household appliance, the garbage disposal, can greatly impact the quality of wastewater. Most new home construction incorporates garbage disposal in its design. Use of these garbage disposal increases both suspended solids and the biochemical oxygen demand (BOD), two common results tested for when measuring contaminant concentrations. A second major determinant of quality of wastewater is the volume of infiltration and inflow into the sewer system. High rates of infiltration and inflow will tend to dilute the contaminant concentration of the wastewater. 2. INDUSTRIAL WASTE Industrial wastes deserve special attention because they can exhibit a wide variety of chemical constituents. The total volume of industrial waste produced within the City of.Renton is small compared with the volume of domestic wastewater. However, an industrial or commercial development can have a considerable impact on the sanitary sewer collection system immediately downstream of the facility. Industrial waste can contain high concentrations of chemicals which can make the waste highly corrosive or toxic. A list of the industries located within the City of Renton is provided in TABLE V-2. 5-32 System Analysis and Conclusions If discharge of an industrial waste to the sanitary sewer system creates problems, then pretreatment of the industrial waste should be considered. Several federal and state regulations - govern the pretreatment of industrial waste. Several industries within the City have obtained National Pollution Discharge Elimination Systems(NPDES) permits as noted in TABLE V-2. The City should assume that those who require permits have them and should rely on the Department of Ecology to fulfill its monitoring responsibilities. According to Department of Ecology records, no violations of NPDES permits involving sanitary sewer discharges have been reported recently.

WASTEWATER QUALITY PROBLEMS A major problem associated with wastewater quality is the generation of hydrogen sulfide that occurs during wastewater transport from its source to the point of treatment. The hydrogen sulfide found in wastewater results from the bacterial reduction of the sulfate ions that are present. Hydrogen sulfide poses two serious problems: it is highly corrosive and has an obnoxious odor. The gas is toxic to humans and has been known to cause death to sewer maintenance workers. The production of hydrogen sulfide is directly related to the biochemical oxygen demand (BOD) of the wastewater. Wastewater, exhibiting a high BOD, will tend to generate more hydrogen sulfide than wastewater exhibiting a lower BOD; therefore, excessive infiltration and inflow will tend to reduce the production of hydrogen sulfide in the wastewater. Hydrogen sulfide is very corrosive to both sewers and pumping'facilities. Hydrogen sulfide released from the wastewater will tend to dissolve on condensationwithin the crown of a sanitary sewer. The hydrogen sulfide retained in the condensation is converted to sulfuric acid by aerobic bacteria. This sulfuric acid will react with the cement bonding.material within concrete pipes, or iron within steel pipes, and can corrode a pipe to the point of structural failure. Sanitary sewer pipes are most susceptible to this type of corrosion in their crowns because that is where most condensation occurs. ' Effects of hydrogen sulfide can be controlled by aeration, periodic cleaning, and .use of noncorrosive pipe materials. If excessive hydrogen sulfide production is evident at a lift station, aeration of the wet well should be considered to reduce the hydrogen sulfide in the wastewater and reduce the effects of anaerobic bacteria which produce the hydrogen sulfide. Periodic cleaning of the sanitary sewers will also remove the biological slime that forms on the pipe walls and produces the hydrogen sulfide. The most effective method of mitigating corrosion by hydrogen sulfide is through the use of noncorrosive pipe materials such as, polyvinyl chloride (PVC) or high density polyethylene (HDPE). Existing pipes experiencing severe corrosion can be rehabilitated through the use of various slip form liners or fiberglass resin liners. In order to control the generation of hydrogen sulfide, the City's maintenance crews routinely flush and clean sewer pipes with inadequate slopes. In addition, all pipes are cleaned before video inspection is performed. Both of these tasks reduce biological growth on the walls of the sewer pipes and reduce the hydrogen sulfide generation potential. 5-34 I CHAPTER VI SYSTEM IMPROVEMENTS CHAPTER VI CONCLUSIONS AND IMPROVEMENTS • A. INTRODUCTION This chapter presents the proposed improvements to the Renton System that are necessary to correct existing deficiencies and accommodate growth. The costs of the improvements and a schedule for implementing them is also included. 1r This Capital Improvements Program is designed, along with the entire comprehensive plan, to be used as a guideline in preparing the capital improvements project list during each yearly budget process. This plan is deliberately intended to be flexible by allowing incorporation of necessary changes that might arise. Many of the proposed improvements are considered to be preventive in nature, i.e., the improvement is intended to happen before a specific facility has failed, a far more desirable process than trying to replace facilities after they fail. Since it is impossible to estimate when a facility will fail, the process of identifying those facilities which are at risk and planning corrective measures must continue. B. CIP RANKINGS The complexity of the City's wastewater utility system requires a method that systematically determines which improvements should be undertaken sooner than others. To assign rankings to the planned improvements, each one was analyzed according to these general categories: Substandard Facility, System Efficiency, Environmental Protection. Each category was further divided into four or more kinds of improvements or standards. Each of these subcategories was assigned a number of points, with the rule that no one improvement could be given more than eight points in any of the three categories.. For each subcategory,each proposed project was"given one point if it provided the benefit described and two points if it provided a solution to an acute problem. The higher the number of points an improvement received, the greater its benefit, or the greater its ability to meet certain standards or policies. This systematic ranking will help direct resources and activities to the appropriate projects. 1. SUBSTANDARD FACILITY A facility qualifies as substandard if it is unreliable, is structurally deteriorating or has hydraulic capacity problems. A project received points if it resulted in the following improvements to a substandard facility: POINTS: 1-2 Reduces or eliminates hydraulic capacity problems. 1-2 Replaces a deteriorating facility or corrects a structural problem 6-1 CHAPTER SIX 1-2 Improves system reliability (i.e.,prevents discharge of raw sewage to any waters, or reduces the potential backup of raw sewage into basements, streets, or other properties) 1-2 Corrects occupation hazard (i.e., reduce dangers to maintenance workers) Maximum Number of Points: 8 2. SYSTEM EFFICIENCY A project can improve the efficiency of the system if it results in a reduction of operation and maintenance costs. Examples of such projects include wastewater flow rate modeling and elimination of lift stations. A project received points for system efficiency if it met any of the following conditions: POINTS: 1-2 Involves improving lift station operation or efficiency 1-2 Involves the elimination of a lift station 1-2 Reduces infiltration and inflow 1-2 Improves understanding and planning of sewer system Maximum Number of Points: 8 3. ENVIRONMENTAL PROTECTION An improvement helps protect the environment if it reduces damage to it or reduces the threat to the public health. Examples of deficiencies that such projectsimprove include: failing septic tanks or sewage overflows into lakes or streams. An improvement received points for environmental protection if it met any of the following conditions: POINTS: 1-2 Eliminates septic tanks 1-2 Improves protection of the public health and safety 1, 1-2 Improves protection of the environment (i.e., land, wetlands, streams, groundwater.) 2 Helps protect Zone 1 of Aquifer Protection Area 1 Helps protect Zone 2 of Aquifer Protection Area Maximum Number of Points: 8 The results of the systematic ranking are presented in TABLE VI-1. After completion of the ranking analysis, the projects were sorted and statistically divided into quartiles (fourths). The first quartile (Quartile I) were those projects with rankings above the 75th percentile. The second quartile (Quartile II) were those projects with rankings between the 50th and the 75th percentiles. The third quartile (Quartile III) were those projects 6-2 Conclusions and Improvements .

The fourth quartile (Quartile IV) were those projects with rankings below the 25th percentile. These project rankings cannot be used solely to prepare the Capital Improvement Program. The project rankings do not take into consideration engineering judgment or scheduling of dependent projects. Engineering judgment involves the trained observation of non-quantifiable impacts of a project. The scheduling of projects involves determining which projects must be completed before other projects can begin. For these reasons, the project ranking is best used as one of many tools to establish a Capital Improvement Program. TABLE VI-2 presents the project priority along with brief comments regarding any inconsistency between the project quartile and the project priority. C. CAPITAL IMPROVEMENT DESCRIPTION A list of all the proposed capital improvements, organized by drainage basin, follows. A brief description of the specific system deficiency, its solution and summary data are included.

MAY CREEK BASIN Devil's Elbow Lift Station Rehabilitation System Deficiency: Construction of the Devil's Elbow Lift Station was completed in 1986. However, significant mechanical difficulties have made the lift station unreliable. In addition, excessive vandalism has occurred due to the lift station's remote location. During peak,wet-weather flows, the Devil's Elbow lift station has overflowed into Honey Creek. The lift station operation must be made more reliable and the facility must be made more resistant to vandalism. Improvement: Correct mechanical problems with lift station in order to meet current design standards. CIP Project No. 1.1 Cost: $167,000 Priority A Beginning: 1991 Completion: 1991 • Devil's Elbow Force Main Repair System Deficiency: Northeast 27th Street has been closed to automobile traffic due to the unstable side slopes of the Honey Creek ravine. The force main for the Devil's Elbow Lift Station, which is located on NE 27th Street has the potential of structural failure if the side slopes supporting the roadway were to deteriorate further. Reconstruction of several sections of the force main is required to increase its reliability. Improvement: Correct instability problems with force main to ensure reliability. OP Project No. 1.2 Cost $75,000 Priority A Beginning: 1991 Completion: 1991 - 6-6 • I' Conclusions and Improvements May Valley Interceptor, Section 2 System Deficiency: The May Valley Interceptor is a facility that is proposed to be constructed by METRO to serve the sewerage needs of this basin. Section 1 of the May Valley Interceptor has been constructed from METRO's East Side Interceptor under Interstate 405 to Jones Avenue NE. Section 2 would extend south along Jones Avenue NE which parallels May Creek to Honey Creek. At this time METRO intends to construct Section 2 of the May Valley Interceptor._ However, the City may need to take the initiative to construct the May Valley Interceptor, Section 2, if METROs schedule does not coincide with the City's needs. Construction of Section 2 of the May Valley Interceptor is necessary to complete the Honey Creek Interceptor and eliminate the need for the Sunset and Devil's Elbow Lift Stations. The May Valley Interceptor, Section 2, would require approximately 5,400 lineal feet of 24-inch gravity sewer. Improvements: Construct gravity sewer service in the May Creek Basin to Honey Creek CIP Project No. 1.3 Cost: $1,448,000 Priority A Beginning: 1991 Completion: 1993 Honey Creek Interceptor, Phase IV System Deficiency: Phases I through III of the Honey Creek Interceptor were completed in 1986. However,frequent mechanical problems with the Devil's Elbow Lift Station and structural problems with the Devil's Elbow force main require that a long-term solution be developed for this basin. The solution is the completion of the Honey Creek Interceptor,Phase IV,which would provide a gravity interceptor from the existing Devil's Elbow Lift Station down to the mouth of the Honey Creek. In conjunction with this project, the May Valley Interceptor, Section 2, must be completed. Honey Creek Interceptor, Phase IV, would require approximately 2,700 lineal feet of 12-inch gravity sewer. Improvement: Complete construction of the Honey Creek Interceptor in order to eliminate the Devil's Elbow and Sunset Lift Stations. CIP Project No. 1.4 Cost: $945,000 Priority B Beginning: 1992 Completion: 1993 6-7 • • CHAPTER SIX Sierra Heights Sewer System Construction System Deficiency: The Sierra Heights area includes residential developments located both inside and outside the City limits. Increased septic system failures have prompted the King County Health Department and the City of Renton to examine providing sanitary sewer service to this residential area. Wastewater from this area would discharge into the Honey Creek Interceptor. This project should not be completed until improvements are made to the Devil's Elbow Lift Station and force main. The Sierra Heights sewer system would require approximately 8100 lineal feet of 12-inch and 8-inch gravity sewer. Improvement: Construct sanitary sewers to replace failing septic systems. CIP Project No. 1.5 Cost: $1,920,000 Priority B Beginning: 1992 Completion: 1994 Sunset Lift Station Elimination System Deficiency: After completion of Section 2 of the May Valley Interceptor and Phase 4 of the Honey Creek Interceptor,the Sunset Lift Station can be placed on standby. Improvement: Place lift station on standby after completion of the Honey Creek Interceptor. CIP Project No. 1.6 Cost: $50,000 Priority D Beginning: 1994 Completion: 1995 Devil's Elbow Lift Station Elimination System Deficiency: After completion of Section 2 of the May Valley Interceptor and Phase 4 of the Honey Creek Interceptor, the Devil's Elbow Lift Station can be eliminated. This would require full dismantling of the existing lift station facilities. The existing force main will remain in place. Improvement: Disassemble and remove existing lift station after completion of Honey Creek Interceptor. CIP Project No. 1.7 Cost: $50,000 Priority D Beginning: 1994 Completion: 1995 6-8 Conclusions and Improvements May Valley Interceptor, Section 3 System Deficiency: This is a project planned by METRO to serve this basin. Section 3 begins at Honey Creek and continues along May Creek to 148th Avenue SE. Section 3 of the May Valley Interceptor would require approximately 10,000 lineal feet of 24-inch gravity sewer. Improvement: Construct gravity sewer service in the May Creek Basin from Honey Creek to 148th Avenue SE. CIP Project No. 1.8 Cost: $3,500,000 Priority E Beginning: 1995 Completion: 2000 Summer Wind Lift Station Elimination System Deficiency: A portion of the plat of Summer Wind lies outside the Honey Creek subbasin. The Summer Wind Lift Station which serves this area can be eliminated through the construction of a gravity sewer north to May Creek. This project will first • require the construction of Section 3 of the May Valley Interceptor. This project would require approximately 1200 lineal feet of 8-inch gravity sewer. Improvement: Disassemble and remove existing lift station after completion of gravity sewers to Section 3 of the May Valley Interceptor. CIP Project No. 1.9 Cost: $500,000 Priority F Beginning: 1998 Completion: 2000 Misty Cove and Baxter Lift Station Rehabilitation System Deficiency: Misty Cove Lift Station currently pumps into the Baxter Lift Station which pumps into the METRO Sewer. It may be possible to eliminate one of these lift stations by providing gravity sewer from the Baxter Lift Station to Misty Cove. The Misty Cove Lift Station has sufficient wet well volume to accommodate this change. Improvement: Improve operation, safety, and reliability of these lift stations. CIP Project No. 1.10 Cost: $450,000 Priority F Beginning: 1996 Completion: 1998 6-9 CHAPTER SIX Denny's Lift Station Rehabilitation System Deficiency: The Denny's Lift Station experiences problems including excessive grease buildup in the wet well and periodic flooding during intense storms. Rehabilitation of the station should be done to provide greater protection and increased reliability. Improvement: Improve operation, safety, and reliability of this lift station. - CIP Project No. 1.11 Cost: $70,000 Priority F Beginning: 1996 Completion: 1996 2. LOWER CEDAR RIVER BASIN East Renton Interceptor System Deficiency: The East Renton Interceptor is currently in the planning stages. Its purpose is to eliminate capacity problems within the existing sanitary sewer systems in the South Highland, Maplewood and Heather Downs subbasins. The planning and construction of this interceptor is in direct response to an enactment of a Sanitary Sewer Moratorium by the City Council under Resolution No. 2764. Upon completion of the . preliminary design and environmental impact statement, a preferred alignment will be selected for final design and construction. The selected interceptor alternative could require as much as 12,300 lineal feet of gravity sewer and possibly the construction of a major sewage lift station. Improvement: Resolve capacity limitations in the South Highlands, Maplewood and Heather Downs subbasins by building the East Renton Interceptor. CIP Project No. 2.1 Cost: $4,445,000 Priority A Beginning: 1989 Completion: 1992 Interim Moratorium Area Improvements System Deficiency: Capacity problems exist in the South Highlands, Maplewood and Heather Downs Subbasins. As a result of the Sanitary Sewer Moratorium in those areas, the City Council directed the Public Works Department to investigate potential areas for interim improvements that could alleviate existing capacity problems within these subbasins. The City is currently investigating several interim improvements. II Improvement: Investigate interim improvements as a means of alleviating of existing capacity problems in the South Highlands, Maplewood and Heather Downs Subbasins. CIP Project No. 2.2 Cost: $332,000 Priority A • Beginning: 1990 Completion: 1991 6-10 • Conclusions and Improvements Cottonwood Lift Station Replacement System Deficiency: The Cottonwood Lift Station is in poor condition,is a contamination threat to the City's aquifer and does not meet current design standards, which include an overflow bypass of the Cedar River. Since this lift station is located within Zone No. 1 of the Aquifer Protection Area, overflows from this station would risk contaminating groundwater: Since this lift station is considered to be permanent, it should be replaced with a more reliable facility. Improvement: Replace lift station with a more reliable one. ClP Project No. 2.3 Cost: $272,000 Priority A Beginning: 1990 Completion: 1991 Central Renton Sewer Replacement, Phase I (Pelle/Garden) System Deficiency: These existing sewers are old and were constructed with inadequate slopes which do not allow self-flushing of the sewer lines. Consequently, maintenance crews are required to flush these sewer lines approximately once a month. These sewers also pose a threat to the City's drinking water supply, due to its location within Zone 1 of the aquifer protection area. This project involves the replacement of approximately 3800 lineal feet of existing 8-inch gravity sewer between Pelly Avenue N,Garden Avenue N, N 4th Street, and N 1st Street. Improvement: Replace old sewers to reduce the threat of aquifer contamination and to reduce excessive maintenance. CIP Project No. 2.4 Cost: $270,000 Priority A Beginning: 1991 Completion: 1992 � I Ll i 6-11 II CHAPTER SIX Central Renton Sewer Replacement, Phase II (Williams/Pelly) System Deficiency: These existing sewers are old and were constructed with inadequate slopes which do not allow self flushing of the sewer lines. Consequently, they require excessive maintenance; crews are required to flush them approximately once a month. These sewers also pose a threat to the City's drinking water supply, due to its location within Zone 1 of the aquifer protection area. This project involves the replacement of approximately 3400 lineal feet of existing 8-inch gravity sewer between Williams Avenue N, Pelly Avenue N, N 4th Street, and N 1st Street. Improvement: Replace old sewers to reduce the threat of aquifer contamination and to reduce excessive maintenance CIP Project No. 2.5 Cost: $200,000 Priority C Beginning: 1993 Completion: 1994 Central Renton Sewer Replacement, Phase III (Houser/Factorv) System Deficiency: These existing sewers are old and are located within the Zone No. 1 of the Aquifer Protection Area, thus posing a threat to the City's drinking water supply if any exfiltration of wastewater occurred. This project involves the replacement of approximately 3200 lineal feet of existing 8-inch gravity sewer between Factory Avenue N, Houser Way N, and N 4th Street. Improvement: Replace existing sewers to reduce the threat of aquifer contamination. CIP Project No. 2.6 Cost: $200,000 Priority E Beginning: 1995 Completion: 1996 Highlands Sewer Replacement, Phase III System Deficiency: Older sewers will not accommodate future wastewater flows within this subbasin. This project involves the replacement of approximately 500 lineal feet of existing 8-inch gravity sewer along Edmonds Avenue NE between NE 5th and NE 6th Streets. This project is to be done in conjunction with the overlay of Edmonds Avenue. The new gravity sewer should be 12-inch in order to accommodate future wastewater flows. Improvement: Replace old sewers during street improvement project. CIP Project No. 2.7 Cost: $51,000 Priority B Beginning: 1992 Completion: 1993 6-12 Conclusions and Improvements South Highlands Interbasin Transfer System Deficiency: Capacity problems exist within the South Highlands Basin and could be alleviated with the replacement and up-sizing of existing sanitary sewers as well as the construction of additional sanitary sewers. These improvements were identified by RH2 Engineering,P.S. in April 1990 during their investigation of facility improvements for the South Highlands Sanitary Sewer Basin. Improvement: Replace and up-size existing sewer and construct new sewers to optimize existing sewers in this area. CIP Project No. 2.8 Cost: $300,000 Priority B Beginning: 1990 Completion: 1991 Honeydew Lift Station Elimination System Deficiency: The Honeydew Lift Station can be eliminated through the construction of a gravity interceptor along private property'. The sanitary sewer would require approximately 2600 lineal feet of 8-inch and 12-inch gravity sewer. The Honeydew Lift Station should be eliminated and the gravity sewer constructed during the development of these parcels. _ Improvement: Disassemble and remove lift station after gravity sewer is provided to this area. CIP Project No. 2.9 Cost: $570,000 Priority C Beginning: 1993 Completion: 1995 J Union 600 Lift Station Elimination System Deficiency: The Union 600 Lift Station can be eliminated through the construction of a gravity sewer to NE 4th Street. A portion of this gravity sewer has already been constructed and the remaining section would require approximately 1000 lineal feet of 8-inch gravity sewer. This project should not be completed until the completion the East Renton Interceptor, which will free up capacity within the Heather Downs subbasin. Improvement: Disassemble and remove lift station after completion of gravity sewers in this area. CIP Project No. 2.10 Cost: $180,000 Priority F Beginning: 1996 Completion: 1997 6-13 • CHAPTER SIX Falcon Ridge Lift Station Elimination System Deficiency: This project involves the construction of approximately 2000 lineal feet of 8-inch and 12-inch gravity sewer from the existing lift station to METRO's Cedar River Interceptor. This project will be done in conjunction with the development of the property between the lift station and the Cedar River. Improvement: Disassemble and remove lift station after completion of gravity sewers in this area. CIP Project No. 2.11 Cost: $700,000 Priority F Beginning: 1996 Completion: 2000 NE 7th Place Sewer Replacement System Deficiency: These existing sewers are currently experiencing wastewater flows that exceed their design capacity. This project involves replacing and up-sizing approximately 840 lineal feet of existing 8-inch gravity sewer to 12-inch sewer pipe. This project may not be necessary if the Honeydew Lift Station is eliminated in the near future. An alternative is to construct a bypass sewer along NE 6th Street as recommended in the RH2 Engineering, P.S. investigation of the South Highlands Basin.

SANITARY SEWER SYSTEM OPERATION A comprehensive maintenance program allows the City to optimize its use of the existing collection system and pumping facilities, thereby extracting the maximum life and capacity of each facility. This permits the same facilities to accommodate greater flow rates and more system connections while minimizing construction of new facilities. A properly maintained facility is less likely to fail. This reduces the operating costs of the utility because of lower damage compensation costs and overtime costs for maintenance personnel. It also protects the environment and the public health by minimizing sewage overflows. B. CURRENT OPERATION AND MAINTENANCE PROGRAM The current operation and maintenance program for.the sewer utility is discussed in this chapter. The operation and maintenance program consists of four elements: Normal Operations Emergency Operations Preventive Maintenance Staffing 1. NORMAL OPERATIONS Normal operation of the sanitary sewer utility is a combination of interaction between the Wastewater Utility Section (located in City Hall) and the Operation and Maintenance Division (located in the City Shop Facility). a. ORGANIZATIONAL STRUCTURE ' The sewer utility operates under the direction of the Administrator of Planning, Building and Public Works, Ms. Lynn Guttmann. The Sanitary Sewer Operation and Maintenance Division is r supervised by Mr. Gary Morrison who reports to the Field Maintenance Supervisor, Mr. Jack Crumley. The Wastewater Utility Section is supervised by Mr. Randall Parsons who reports to the Utility Systems Division Manager, Mr. Richard Anderson. Mr. Jack Crumley and Mr. Richard Anderson report to Ms. Lynn Guttmann. The certifications based on successful completion of training courses and examinations held by the Operation and Maintenance and Engineering staff are listed in Table VII-1. Training consists of special courses and seminars specifically designed for the requirements of sanitary sewer utility employees. The training is offered through such organizations as the APWA 7-1 r-, CHAPTER SEVEN TABLE VII-1: CITY PERSONNEL AND CERTIFICATION OPERATION AND MAINTENANCE PERSONNEL PERSONNEL POSITION CERTIFICATION RESPONSIBILITIES Gary Morrison Supervisor Wastewater Collection III Oversees and manages sanitary sewer system operation and maintenance.

Renton's policy .of supporting and promoting operator training should be continued. As the complexity of the system increases and as the service area expands, the need for trained, efficient staff to keep pace with public demand and advances in technology will become imperative. New employees need orientation and basic information while more experienced employees can improve by continued training. Training opportunities are of such importance to effectively operating the system that Renton has linked them to its overall personnel evaluation program. Employees are evaluated and promoted through a set of job categories that are increasingly well paid. It is essential that the promotional program continue to be closely linked with the training program, not only because it promotes efficient operation, but because mandatory certification of wastewater utility workers is required by the state. Qualifications and training requirements for obtaining and maintaining certification are stipulated by the State Department of Health. The City Council and Administration have approved expenditures for increased training with the result that improved proficiency levels have occurred in the last five years. b. COMMUNICATION Efficient and economical functioning of a team requires adequate provision for regular, effective communication among its members. The normal channels of communication available to maintain effective coordination are: Vehicular two-way radios Regularly kept work logs Regular inspection reports Daily work assignment meetings Inventory and other record keeping practices Emergency phone numbers for "on-call" employees Direct, City owned telephone connection to City Hall Weekly staff meetings The sewer utility does not have a comprehensive system operation manual; however, lift station facility operation and maintenance manuals are available for staff reference. City staff have maintained the policy of requiring complete operation and maintenance manuals for all new equipment and facilities. In addition, we recommend that a system wide Operations and Maintenance manual, including emergency response procedures, be prepared and updated on a regular basis. 7-3 CHAPTER SEVEN c. EQUIPMENT AVAILABILITY • Sewer maintenance staff is equipped primarily with rented equipment. The equipment available for daily use includes rolling stock, shop tools and incidental equipment as well as other portable equipment for field use. The vehicles and other rolling stock are listed in Table VII-2 with a description of their primary use in the department. A description of each vehicle and its uses is presented below. The existing inventory appears adequate at current staffing levels but should increase in proportion to customer increases. The City should examine the backup capabilities of the inventory, based on critical equipment or facility failure, and make provisions for additional material procurement on a short notice basis where necessary. • TABLE WI-2: SANITARY SEWER DEPARTMENT EQUIPMENT(1989) ROLLING STOCK Vehicle# Year Vehicle Description C-75 1976 Utility TV inspection unit D-58 1987 Lift station utility truck D-51 1987 Manhole and line service truck E-71 1986 Aquatech high velocity sewer Jet and vacuum unit S-91 1976 Mechanical rodding OTHER EQUIPMENT Amount Equipment Description 4 Wacker compactors 1 3-inch trash pump 4 Trash diaphragm pumps 1 Chainsaw 1 Set of emergency lighting 1 Emergency generator 7-4 • Operations and Maintenance 1 UTILITIES T.V. INSPECTION UNIT EQUIPMENT #C-75 This unit is a closed-circuit T.V. system used for inspecting underground utility lines, rJ primarily sanitary sewer and storm drain lines. It is fully self-contained with a generator, compressor, and water supply. Its primary use is to determine conditions of existing lines and any repairs or replacement necessary. The T.V. van is an important part of the t maintenance program to help determine priority areas that require further attention and maintenance. LIFT STATION UTILITY TRUCK EQUIPMENT #D-58 This vehicle is used by the lift station crew for inspection, maintenance and repair of sewer pump stations. It is equipped with a crane used for lifting.pumps and equipment as needed, and utility compartments for parts, tools, etc. This vehicle is also used to transport the mechanical rodding machine and to assist with other maintenance procedures as needed. MANHOLE AND LINE SERVICE TRUCK EQUIPMENT #D-51 This vehicle is used by the line crew for inspection and repair of manholes and lines. It is equipped with a crane hoist for lifting and setting manhole rings and equipment used in repair work. It carries parts used in sewer line repair such as couplings, fittings,plugs, etc. It is also equipped with an auxiliary hydraulic power unit that operates jackhammers, compactors, and pumps making this vehicle self-contained for exposing and excavation procedures. AQUATECH HIGH VELOCITY SEWER JET AND VACUUM UNIT EQUIPMENT EQUIPMENT #E-71 The Aquatech has a wide variety of uses in the utility maintenance programs. It is primarily used to clean sewer lines and remove solid debris (i.e.,rocks, silt, dirt) from the lines that could create flow restrictions and blockages. There are a number of lines in the City, primarily in the downtown area, that have inconsistent grades creating septic conditions within the lines. A part of the maintenance program is to use the Aquatech to flush water through these particular lines periodically to prevent those conditions from occurring. The Aquatech is the primary equipment used for emergency blockages in the lines and is used to assist T.V. inspection by setting cables. • 7-5 CHAPTER SEVEN MECHANICAL RODDING MACHINE EQUIPMENT #S-91 The mechanical rodder is used to remove roots and grease that accumulate within sewer lines creating flow restrictions and blockages. Numerous lines throughout the City have been examined and discovered to have had a history of problems created by roots and grease. These particular lines are rodded periodically to ensure there is no interruption of flow. d. ROUTINE OPERATIONS Routine operations involve the analysis,formulation, and implementation of procedures to ensure that the sanitary sewer facilities are functioning efficiently. The utility's maintenance procedures are good, with repairs being made promptly so customers do not experience unnecessary inconvenience. Side sewer maintenance can be a major problem within a sanitary sewer system. Side sewers are owned and should be maintained by the individual property owners. City policy is that individual property owners are responsible for maintaining their side sewers. If a problem occurs, the property owner is to contact a private plumber to investigate and correct the problem. If the property owner can show that the problem is within the publicly owned sewer main, then the City will correct the problem and reimburse the property owner for expenses incurred e. RECORDS Providing time for keeping and maintaining accurate records should be an integral consideration in determining the time to be allotted to any departmental task. Adequate records are an essential tool in utility management and operation,providing the supporting data for operations assessment and long-term planning, while saving time and reducing difficulty when trouble arises. The sewer utility has need for several types of records: facility operation, records, personnel, customer contact, inventory, and facility maintenance and repair. These and other appropriate documents should be legible, concise, permanent, accurate and accessible. Their importance to the efficient functioning of the utility is critical. Up-to-date maps of the sanitary sewer system are important for operation and maintenance. Changes or additions to the sanitary sewer system should be added as they occur. The City maintains an updated 1"= 400' scale map of the sanitary sewer system that is useful to the operations and maintenance staff. These utility maps show the sanitary sewer size and location, manhole location and number, cleanout location, and lift station and force main locations. As- built drawings of much of the existing sanitary sewer system are kept on file in the Utility 7-6 ' I' Operations and Maintenance Systems Division at City Hall. This information is useful in helping the operation and maintenance staff to locate sanitary sewer lines and service connections from these drawings. Plat maps or construction drawings for new sanitary sewer extensions within the distribution system should continue to be kept for the sanitary sewer system. C. EMERGENCY OPERATIONS The City responds to emergencies involving the sanitary sewer system through the use of on-call personnel. The Sanitary Sewer Department does not have an emergency response plan that identifies how Renton should react to an emergency. It is recommended that the City prepare an emergency response plan for the sewer utility. This plan should include the functions and responsibilities of personnel, procedures to be followed, maps of each facility, contact lists, and communication procedures. The emergency response procedures should be available both in report form and through a computer program prepared specifically for that purpose. The - emergency response plan should be updated every two years. D. PREVENTIVE MAINTENANCE _; Maintenance schedules that meet or exceed manufacturer's recommendations should be established for all critical components in the sanitary sewer system. The following schedule should be used as a minimum for preventive maintenance: Sewage Lift Stations Daily: Observe and record motor current draw; check packing; log and record pump motor hours; check motor noise, temperature, vibration. Weekly: Check security. Semiannually: Change motor oil. As Needed: Recoat structures and piping; maintain electrical and hydraulic controls. Wet Well Facilities Weekly: Check security: Check float settings. Annually: Check interior condition,ladder,hatches,etc.,in wet well. • As Needed: Recoat interior as needed in wet well (estimated 10 to 15 year frequency). Sanitary Sewer System Twice Per Week: Check inspection manholes .for flow reduction. Clean lines when flow in sewers is reduced. Semiannually: Cut roots in sewers with root problems. 7-7 CHAPTER SEVEN Tools & Equipment 1. Rolling Stock Daily: Check all fluid levels and brakes. As Needed: Replace fluids and filters in accordance with manufacturer's recommendations • (or more frequently depending on type of use). 2. Tools As Needed: Clean after each use; lubricate and maintain as necessary. E. STAFFING The preventive maintenance procedures and normal as well as emergency operations of the utility are described in the previous sections. The hours of labor and supervisory activity required to effectively carry out the work of these on-going maintenance and operations schedules and engineering responsibilities form the basis for determining adequate staffmg levels. 1. MAINTENANCE AND OPERATIONS STAFF The current staff organization is illustrated in Table VII-1. There are at present seven employees, including supervisory personnel and maintenance workers, who operate and maintain the sanitary sewer system. The tasks that are performed by sewer utility staff include inspection, testing, installation and repair of system facilities and routine preventive maintenance, record keeping, administrative tasks, and corrective action required in response to emergencies. The hours of work required to adequately maintain the sanitary sewer system are shown in Table VII-3: For preventive maintenance alone, the annual hours total 3,589, or 69 crew hours per week. This requires nearly 2 crew members working full time, i.e.,40 hours per week, excluding vacation, sick leave, and all other tasks not related to preventive maintenance. The hours of work required for operational tasks for the sanitary sewer system are shown in Table VII-4. For operational tasks alone, the annual hours total 8,535, or 164 crew hours per week. This requires more than 4 crew members working full time, i.e., 40 hours per week, excluding vacation, sick leave, and all other tasks not related to operation of the sanitary sewer system. The total operation and preventive maintenance time required is 12,124 hours per year, which is equivalent to six people working full time, 40 hours per week. 7-8 Operations and Maintenance If due consideration is given to the hours involved in vacation, holiday, illness, meetings, training, on-the-job travel and startup time, then the total number of hours actually available for performing the work of operation and maintenance diminishes to a level of approximately 1,662 hours per year per crew member. At .this rate, a staff of eight full-time maintenance crew members is necessary to accomplish preventive maintenance and normal operations activities and respond to emergencies. �—' This analysis indicates that the Sanitary Sewer Operation and Maintenance Department is not adequately staffed to regularly perform the basic tasks required to provide minimum recommended maintenance to the system. An expansion of the system requiring new service connections and/or additional facilities, without enlargement of the staff, will result in increased neglect of necessary maintenance. In view of predicted population growth in the service area over the next several years and the growing demand for sanitary sewer service, the need for additional staffing will continue. Many arguments support the wisdom of adequate staffing in any work place. The most persuasive argument relevant to a complex sanitary sewer system is that short staffing cause preventive maintenance schedules to be neglected. When routine,regular preventive maintenance tasks are dropped, misfortune results, increasing both breakdown maintenance and excessive reliance on expensive standby equipment required to resolve emergencies. Regular performance of all necessary work in the Sanitary Sewer Operation and Maintenance Division, with the current number of service connections, will require additions to the present maintenance crew. The expected increase in the number of service connections should serve as L further impetus to develop a staff of an adequate size to effectively operate and maintain the system. The size of the maintenance crew should be increased from six to eight personnel while keeping the supervisor. This addition to the staff will be required before there are adequate crew hours available to carry the full work load of the Utility without neglecting preventive maintenance, emergency preparedness,or safety precautions. Maintenance and technical staff additions should be accompanied by additions to the clerical, secretarial and other support staff needed to ensure that record keeping, billing,.public relations, communications and other general functions of support staff are performed with the accuracy and timeliness required. 2. WASTEWATER UTILITY ENGINEERING STAFF r The current engineering staff organization is illustrated in Table VII-1. There are currently four employees involved in utility engineering tasks; however, the Wastewater Utility section supervisor works part-time in the stormwater utility. The engineering staff is responsible for two major tasks, administrative and capital improvement projects. 7-9 CHAPTER SEVEN The various administrative tasks and the hours of work required are shown in Table VII-5. The number of hours required for each task is not easily defined; therefore, work loads have been �. estimated based on a full-time employee (FIE). Administrative tasks alone requires approximately 2.0 FTE's. Therefore, it is evident that the administrative activities require a major portion of the engineering staff resources. Table VII-5 also shows the capital improvement projects which are currently under way within the City. These five projects require approximately 0.8 1-(11.'s. The total time required to perform all the tasks that the City is currentlyperforming is approximately 2.8 F1'E's, which corresponds very closely to their current staffing level of 2.6 F 1'h's. Most of the capital improvement projects identified in the 1983 Comprehensive Sewer Plan were not completed. The primary reason for the City's inability to carry out a capital improvement program is not a lack of available funding but a past and current lack of engineering staff to design or manage the projects. The level of staffing within the City's Wastewater Utility section may be the biggest obstacle to the implementation of this plan. The proposed capital improvements require that approximately 14 to 16 projects are under way at any one time. Current staffing levels can only accommodate approximately four capital improvement projects. In order to implement this plan, additional staffing of approximately 2.5 FTE's will be required in order to accommodate 14 to 16 capital improvement projects per year, beginning in 1991. Additional administrative tasks which are ?__'I recommended in this plan are (1) prepare new ordinances and revise existing ordinances, (2) setup and administer grease trap management and certification ordinance, (3) inventory and update hydraulic computer model, and (4) perform computer analyses using the sewer system hydraulic model. These tasks will require additional staffing of approximately 0.5 FTE's. This will bring the total additional staffing, requirements for both administrative tasks and capital improvement projects up to 3.0 FTE's, bringing the total wastewater staffmg level up to 5.5 FI'E's. These additions will likely result in the section supervisor increasing supervision duties and eliminating project managements duties. • 4 I I 7-10 Operations and Maintenance TABLE VII-3: STAFFING TIME FOR PREVENTIVE MAINTENANCE FACILITY OR FREQUENCY OF QUANTITY IN TIME REQUIRED EQUIPMENT MAINTENANCE SYSTEM TIME PER UNIT PER YEAR Lift Station Annually 22 Stations 16 Manhours 352 Hours Maintenance Sewage Pump and Annually 45 Pumps 8 Manhours 360 Hours Motor Maintenance Check Inspection Twice per Week 106 Manholes 10 Minutes 1837 Hours Manholes Root Cutting Semiannually 19200 LF 1500 LF/30 Mhours 768 Hours, Grease Removal Annually 5200 LF 1500 LF/30 Mhours 104 Hours -, Line Flushing Once per Month 1 Set 14 Manhours 168 Hours TOTAL PREVENTIVE MAINTENANCE 3589 Hours TABLE VII-4: STAFFING TIME FOR OPERATION TASKS TASK TIME PER TIME REQUIRED ACTIVITY FREQUENCY ACTIVITY PER YEAR Lift Station Inspection Daily 7,Mhours/Day 2555 Hours Video Inspection Once per Week 30 Mhours/Week 1560 Hours Work Logs Daily 10 Mhours/Day 2600 Hours Vehicle Inspection Daily 0.5 Mhours/Vehicle 650 Hours Staff Meetings Daily 0.5.Mhours/Day 910 Hours Tool and Once per Week 5 Mhours/Week 260 Hours Equipment Cleaning TOTAL FOR OPERATIONS 8535 Hours Source: Gary Morrison 7-11 • ' I CHAPTER SEVEN iI TABLE WASTE WATER UTILITY ENGINEERING STAFF TIME NUMBER OF ENGINEERING TASKS EMPLOYEES Section Supervison 0.20 FTE's Latecomers Agreement Administration 0.20 FTE's Sewer Moritorium Administration 0.30 FTE's Plan Review Support 0.60 FTE's Comprehensive Sewer Plan Update • 0.20 FTE's Customer Service Support 0.25 FTE's Support to Other Divisions/Departments/Agencies 0.25 FTE's TOTAL ADMINISTRATIVE TIME 2.00 FTE's Major Capital Improvement Projects East Renton Interceptor 0.20 FTE's Minor Capital Improvement Progects West Kennydale Interceptor 0.20 FTE's Interim Sewer Improvements 0.10 FTE's Lake Washington Sewer Improvements 0.10 FTE's Park Avenue Interceptor 0.10 FTE's Infiltration and Inflow Program 0.10 FTE's TOTAL CIP TIME 0.80 FTE's TOTAL ENGINEERING TIME 2.80 FTE's FTE's=Full Time Employees Source: Randall Parsons,Stormwater and Wastewater Utility Supervisor 7-12 CHAPTER VIII FINANCIAL IMPACTS • t l CHAPTER VIII FINANCIAL ANALYSIS A. INTRODUCTION This chapter considers the financial impacts that the Capital Improvement Plan (CIP), recommended in Chapters 5 and 6, will have on the wastewater utility's budgeting process. The proposed wastewater utility CIP consists of the rehabilitation, replacement and new construction of sewer facilities that are necessary to meet the policy goals stated in Chapter 3, the design standards and criteria presented in Chapter 4 and the service needs that will result from anticipated growth. This chapter also presents a financial analysis of the wastewater utility which identifies its historical and projected future expenses and compares them to available and projected revenues in order to determine the necessary rate adjustments. A utility rate study that evaluated the operation of the 401 and 421 funds and made specific rate recommendations was completed in November 1989 (Water and Wastewater Rates Managements Analysis, RH2 Engineering P.S.). This rates management analysis was intended to guide rates management for a period of two years while a reorganization of the Public Works Department was taking place. During the first quarter of 1992, the financial models developed in the rates management analysis should be updated so that recommended rates can be adjusted to accurately reflect the current financial situation within the utility. The utility's financial situation has also changed because of new state laws regarding how fees and charges must be calculated(Substitute House Bill 2929), and because the City is taking steps to adjust all of its rates, fees, and charges to meet its projected costs. In this document two sets of numbers are used. Current 1990 dollars are used to project the costs { of operations, maintenance, and capital improvement programs. However, several factors may affect the accuracy of those projections. The most significant factor is inflation. Although we cannot predict the exact amount inflation will increase costs, we estimate it will raise them by 5% a year. Other factors that may affect future costs that we have not included in our cost estimate are contractor availability, technological advances, and changes in laws and policies. B. WASTEWATER UTILITY EXPENSES AND REVENUE REQUIREMENTS There axe four major expenses of the wastewater utility, which fall under two broad categories-- operating expenses and actual construction costs for CIP projects. Operating expenses include costs for operations and maintenance and METRO charges. Actual construction costs include the expenses for implementing the CIP and debt service costs. Inflation,defined as a general rise • in prices, affects each of these expenses to a different degree. A summary of the major expenses 8-1 CHAPTER EIGHT of the wastewater utility is shown on FIGURE 10. A more detailed breakdown of these costs is shown on TABLE VIII-2A & 2B . A detailed description of each expense is presented below. To determine the revenues needed to meet each expense, one must forecast future levels of 1) inflation, 2) customer service increases, 3) METRO rate increases, 4) the increases in operations and maintenance costs, 5) the City's share of costs for financing the CIP, and 6) anticipated revenues from other sources to finance the remaining portions of the CIP. C. OPERATING COSTS AND REVENUES All operating costs fall into two general categories: 1) The city's operations and maintenance expenses (controlled by City's budget process) and 2) the METRO sewage treatment charges (no direct control by the city). A summary of these costs is shown on FIGURES 10 and 11. It is evident from FIGURE 11 that the majority of the wastewater utility expenses are a direct result r , . of METRO changes. 1. Municipality of Metropolitan Seattle (METRO) Charges METRO charges for wastewater treatment and disposal. As part of its service contract with METRO, the City collects that charge from its customers through the utility billing division and passes it on to METRO. METRO has increased its rates substantially and will continue to do so to meet new treatment requirements. METRO treatment services are forecast to increase at an average annual rate of 13%. 2. City of Renton Operations and Maintenance a. Costs The estimated costs to operate the wastewater utility include salary costs for the operation, maintenance, engineering and administration of services, taxes, office supplies, debt service, and consulting fees. For eighteen months the wastewater utility has been in transition because of the Public Works Department's reorganization which separated the wastewater utility • from the water utility. As part of the reorganization, the number of staff and additional staff positions for each utility were identified. For purposes of this financial analysis,recommended staffing levels for operating the wastewater utility were predicted to be reached within a five-year period in order to keep pace with anticipated growth. Inflation for labor is estimated to be 5% annually, with an additional 5% step increase applicable to 50% of the work force. Other expenses are anticipated to increase at the estimated inflation rate of 5%. 8-2 I � Financial Analysis • CITY'S REVENUE BREAKDOWN SUMMARY FIGURE 9 s• Revenue projection requirements based on proposed capital improvements and operation and maintenance. 3 5 206M::: W ' 2 SM ::1.ZOM•�' 113M ill gig:. 1 0.96M 0.98M 0.98M 0.99M 1.00M 1.02M 1990 1991 1992 1993 1994 1995 YEAR City Operations 0 City Proposed CIP • 8-3 • .

cost estimates are in 1990 dollars CHAPTER EIGHT b. Revenue Requirements For purposes of the financial analysis, the estimated revenue requirements for the next five years (1991 to 1995) were based on the 1990 operating budget--which reflects the new organization with additions for planned new services and inflation. Customer service growth was assumed to occur at 2% per year, which increases revenues from rate collection by 2%. The capital budgets were based on the five-year CIP recommended in this Plan. In addition to reflecting the new organization, the 1990 operating budget was used as a base rather than actual historical expenditures, because the old organization's cost allocations were imprecise and based on a time-reporting system which was unreliable. The transition's effect, however, has not been completely reflected in • the currently available financial information and will not be completely reflected until the City obtains the first nine months of 401 and 421 fund operations of 1991. D. CIP COSTS AND REVENUES 1. Capital Improvement Plan Costs The recommended CIP presented in this Plan consists of improvements necessary to serve the projected service area's population at saturation at the lowest reasonable cost. Consequently, the CIP's recommendations are based on saturation conditions and will be implemented as they are needed. The project costs listed here are intended for budgetary purposes only, because they are based on current construction costs and should be adjusted for actual inflation depending upon the actual construction date. The cost for the recommended CIP in the City's budget process is shown in the annual budget in the 421 account. The costs for all of the improvements have been estimated, based on current information available. It should be reiterated that changes in system flow rates, system growth, financial policies, and regulatory requirements all contribute to adjustments in long-range planning. We recommend that financial goals be evaluated every five years, and that a detailed cash flow analysis be conducted annually. TABLES VIII- 2,3A & 3B present the capital improvement program as recommended in this Comprehensive Plan with its estimated costs. TABLE VIII-2 summarizes these annual costs of the CIP program showing the total project cost (current and inflated dollars) and the City's share of the program costs (current and inflated). TABLE VIII-2 also presents the City's share as estimated in the Rates Management Analysis accomplished during 1989. FIGURE 12 graphically presents the information provided 8-8 Financial Analysis in TABLE VIII-2. • TABLES VIII-3A&3B show an annual breakdown for each capital improvement project using current dollars. These estimates of funding responsibilities are based on the financial policies presented in Chapter 3. Debt service is a major cost of operating a wastewater utility. The majority of funding for the CIP has historically been provided through revenue bond sales, which means the utility borrows money from inventors while agreeing to repay those investors part of their debt with interest each year. This debt service (principal and interest) is funded from the 401 account (Utility Operations and Maintenance) because the debt service is a high priority lien on the revenues of the utility. Specific restrictions are contained in the bond covenants which restrict financial procedures of the utility. For example, the wastewater utility is required to set rates that must exceed its costs for operating and maintaining the system, cover payment of the debt service and cover an additional specified percentage of debt service. 2. Revenue Sources for CIP a. City Share In the financial analysis, the new debt service was calculated as the amount necessary to fund the City's share of inflated CIP costs. The analysis also indicates how this additional debt service affects the operating costs identified in the Rates Management Analysis (RMA). That adjustment to the RMA will determine the rate adjustments necessary to accomplish the CIP. Those costs will be recovered from customers based on their r specific degree of benefit and cost responsibility. The City's share of funding originates from three different sources; Revenue Bonds, General Obligation Bonds and the Public Works Trust Fund. These funding sources are discussed in detail below. 1) Revenue Bonds Revenue bonds are issued and sold by the City when large amounts of money are needed to build general purpose capital improvements that benefit the City as a whole. The City, like other municipalities, is capable of issuing tax-exempt bonds. The principal and interest payments for such bonds are repaid from general revenues, connection charges, assessments and interest earned on investments. In order to qualify to sell revenue bonds, the City must show that its net operating income (gross income less 8-9 CHAPTER EIGHT expenses) is equal to or greater than 1.3 times the annual principal and interest due for all outstanding bonded indebtedness. The 1.3 factor is commonly referred to as the "coverage factor". 2) General Obligation Bonds The City has the authority to levy a tax (subject to a vote of the people) that could be used to pay principal and interest costs of a general obligation bond issue. The City has not used this means of revenue generation for the wastewater utility and does not plan to unless a serious disaster occurs that requires massive improvements and/or replacements beyond the City's ability to fund it through other sources. 3) Public Works Trust Fund Loans Low-interest rate loans are available from the state for replacement of existing sewer system facilities. Interest rates vary from a low of 1% to a high of 3% depending upon the City's matching share. It is emphasized that these low interest rate loans are for replacements only and can not be • used for accommodating growth. These loans can be utilized effectively for replacements in the Central Business District (CBD) and other fully developed areas of the City. b. Other Revenue Sources For CIP This section presents the anticipated funding for the CIP from sources other than rates revenue. Five funding sources are identified and these are discussed in more detail below. 1) Grants Federal and state loan and grant programs are available for wastewater - • capital improvement projects. These programs are primarily designed to fund improvements that upgrade wastewater treatment facilities in order to comply with Federal Clean Water Act (PL92-500). With budget cutbacks at both the federal and state level, the possibility of receiving government funding for a portion of the recommended improvements at this time is remote. Should additional funds be made available, the City should explore the feasibility of obtaining funds from these sources. 8-10 Financial Analysis The Centennial Clean Water Fund is an example of state grant funding which is currently available. This grant fund's highest priority is to eliminate public health emergencies and secondly, to improve water quality. The City should continue to pursue these funds. 2) Municipality of Metropolitan Seattle (METRO) METRO funds are available for the construction of interceptors and local service extensions if the investment can be justified. Currently METRO limits its investment to projects where the amortized capital cost of the project can be recovered through METRO fees collected from the residential customer, or equivalent, that are served by the extension at the time of project completion. Based on this policy,METRO could construct the May Valley Interceptor and other improvements. 3) LID (Local Improvement District) Assessments LID assessment income is paid to the City from assessments levied against specific properties which have benefitted from improvements in a defined area. Typically, Local Improvements District's (LIDs) are formed by the City at the written request (by petition) of property owners within a specific area of the City. Upon receipt of a sufficient number of signatures on petitions, a local improvements area is defined and improvements are designed for it. Each separate property in the LID is assessed in accordance with the special benefits the property receives from the sewer system improvements. Generally, it is the policy of the City to assess the benefitted properties 100 percent of the cost of the improvements plus the general facilities and sewer connection charges. LID projects may be divided into two categories. a) Improvements of Local Interest If necessary, specific problems, such as excessive septic tank failures, can be corrected through an LID. If not necessary, these projects can be postponed until a later date when the area needs or desires it. 8-11 CHAPTER EIGHT b) Improvements of Regional Interest These project are beneficial to an area larger than an LID and are initiated by the City. While LID funding would help, the project is of such importance that a lack of LID should not delay it. If an LID cannot be formed, additional funding from other sources " (including the City) may be necessary. 4) Developers City policy requires that all developers/property owners take financial responsibility for the necessary improvements before their development benefits from them. This responsibility may be satisfied in one of the following ways. In all cases, developer/property owners should be required to pay for the costs to the extent their property benefits from the facility installed (their fair share). a. If the utilities necessary are already installed, the developer/property owner will reimburse the party (city or private) that installed the facility through a latecomer -. agreement or special assessment district. b. If the utilities necessary are not installed, then the developer/property owner must extend or make improvements to the facilities following routes that comply with the City's Comprehensive Sewer Plan. If the Plan is not definitive for that area, then the facilities will be extended and installed in a manner that best serves the City of Renton's citizens as determined by the utility system manager. If the facilities installed potentially benefit other properties, a latecomers agreement may be requested. If the facility required by the City is determined by City Council to be significantly more expensive because of oversizing or routing requirements, then the Council may agree that the City participate. . If a City capital improvement project is being planned, designed or constructed, developer/property owners could choose to participate fmancially in the City's project rather than make the improvements themselves. 5) Other 8-12 Financial Analysis This category of funding responsibility is primarily for participation by other municipalities, such as adjacent cities or districts. Negotiations need to be accomplished to finalize funding responsibilities before annual adjustments to the CIP and rate increases. c. Contingency Revenue Plan If the funding from other sources does not happen as anticipated, or on the schedule anticipated, then the City should adjust this Plan's CIP. Alternative adjustments available to the City are as follows: Reduce the scope and magnitude of the improvements with corresponding dmg reductions in cost, Defer that portion of the improvements necessary for the benefit of others until the funding is obtained, Proceed with.the CIP as recommended in this Plan and finance the other beneficiary's share with the provision that these other costs should be recovered including interest costs. It is critical to implementation of the CIP that these funds be obtained from other funding sources. The level of funding from other sources is based on the current perceived degree of benefit from each project; this may change based on the actual degree of benefit assessed at the time the project is planned to begin. E. FINANCIAL ANALYSIS The City has control of only approximately 40% of the total wastewater utility budget; METRO charges are responsible for approximately 60% of the total.budget. The City's major source of revenue is from sewer collection charges from its customers. Theses charges provide the necessary revenue for the operation and maintenance of existing sewer facilities and for the City's share of the CIP. The financial analysis summarized in TABLE VIII-1 (page 8-4) illustrates that the City must raise its sewer collection charges by 64.4% over the next four years. This is equivalent to an average annual rate increase of approximately 13.2% per year. However, the same financial analysis also illustrates that these rate increases are not uniform but require a greater percentage increase in 1992 (18.1%) then taper off to a smaller percentage increase in 1995 (8.8%). The rate increases depend on several factors which can change. These factors are summarized below: • 8-13 CHAPTER EIGHT 1. The customer base for the City is forecast to grow at an annual rate of 2% over the next five years. If this growth rate is greater than 2%, adjustments to sewer collection rates may be less than projected; however, if the customer base increases at less than 2% per year, then adjustment to these sewer collection rates will lead to an increase above what is shown in TABLE VIII-1. 2. A significant portion of the wastewater utility's budget cover operations and maintenance personnel costs. If recommended additions to the staff do not occur, then the rate increases shown in TABLE VIII-1 could be reduced. The cost savings would be offset, however, by the consequences of having inadequate and unqualified personnel; the wastewater utility would not function efficiently and - would not provide adequate services to its customers. 3. The financial analysis assumes the CIP in this Plan will be implemented. If it is not, whether deliberately or unintentionally, then the required rate increases presented in this financial analysis will change. It should be noted that delaying the implementation of this CIP may initially result in lower rate increases; however, if facilities fail, then unplanned and costly repairs will be needed, which often results in excessively high rate increases in the future. Currently, the City Council and wastewater utility are implementing financial reviews through the annual budget process. These reviews allow the wastewater utility access to the latest and • most accurate financial date, allowing more informed decisions. The wastewater utility will continue to work with the City Council to recommend the necessary rate increase needed to maintain and improve the system in order to provide the residents of the City with effective, safe, and reliable sewage disposal service. 8-14 APPENDIX A SEWAGE LIFT STATION DATA SHEET SEWAGE LIFT STATION DATA SHEET LIFT STATION NAME Airport • LOCATION West Perimeter Road/Airport CONSTRUCTED 1986 STATUS Active REHABILITATED PROJECT -S-424 PUMP AND MOTOR DATA PUMP NUMBER 1 2 MANUFACTURER S & L S & L MODEL NUMBER 4B2B 4B2B FLOW RATE 100 100 T.D.H 54 54 MOTOR NUMBER 1 2 MANUFACTURER GE GE MODEL NUMBER 5K213DP6752A-TA 5K213DP6752A-TA HORSE POWER 7.5 7.5 VOLTAGE 230/460 230/460 R.P.M./PHASE 1750/3 1750/3 FORCE MAIN DATA LENGTH 195 LF SIZE 4" DI LIFT STATION CONSTRUCTION DESCRIPTION Wet well mounted lift station (Smith & Loveless Design) with fiberglass enclosure EMERGENCY POWER CONNECTION NO HEATING Yes CONTROL Floats VENTILATION Yes TELEMETRY Yes SEWAGE LIFT STATION DATA SHEET LIFT STATION NAME Azalea Lane LOCATION 2310 Aberdeen Ave NE CONSTRUCTED 1979 STATUS Active REHABILITATED PROJECT S-271 PUMP AND MOTOR DATA PUMP NUMBER 1 2 MANUFACTURER S & L S & L MODEL NUMBER 4B2B 41321 FLOW RATE 100-150 100-150 T.D.H 44 44 MOTOR NUMBER 1 2 ll MANUFACTURER S & L S & L MODEL NUMBER 11954-XX2978 11954-XX2978 HORSE POWER 7.5 7.5 VOLTAGE _ma__ 201) R.P.M./PHASE 1766/3 1766/3 FORCE MAIN DATA l LENGTH 1250 LF SIZE 6" PVC 'ff LIFT STATION CONSTRUCTION DESCRIPTION Wet well mounted lift station (Smith & Loveless Design) with fiberglass enclosure EMERGENCY POWER CONNECTION Yes HEATING Yes CONTROL Float VENTILATION Yes TELEMETRY Yes J.

As said street ex- tends easterly from its intersection with the Talbot and Spring- brook Roads, it is known as Carr Road. (10.) "The existing crossing" is a short main extension of the Springbrook Line crossing the Talbor Road from manhole No. 2 to a spot near the boundary of Lots 1 and 2 of Scott's Terrace. I (11.) "The proposed crossing" is a main extension of the Talbot Road Line proposed to be constructed from manhole No. 1 to a spot near the boundary of Lots 4 and 5 of Scott's Terrace. (12.) "U.L.I.D. 11" is a Utility Local Improvement District, numbered 11, being formed by Cascade Sewer District, and includes • Lots 12, 13, 14, 15, 17, 18, 19, 20, 21, 22, 27 and 28 of Scott 's Terrace, and that portion of the northerly 150 feet of the Rad- ovich Property which lies east of the southerly prolongation of the westerly boundary of Lots 17 and 18 of Scott's Terrace. (13.) "METRO" is the Municiplaity of Metropolitan Seattle, (14.)

The METRO Line continues generally easterly along South 177th Street, then continues generally southeasterly along 98th Avenue South, and then continues easterly. II. FACTUAL BACKGROUND (1.) Under date of August 11th, 1970, the City and Safecare- Careage entered into the Safecare-Careage Contract which permitted Safecare-Careage to build the Springbrook Line hereinabove -?- defined. (2.) Said contract provided for reimbursement to Safecare- Careage, subject to the laws and ordinances of the City of Renton, by the owner of real estate who did not contribute to the orig- • inal cost of the improvement and who subsequently wished to tap - into or hook onto or use the facilities. (3.) Said contract also reserves to the City the right to make or cause to be made extensions of or additions to the above-mentioned improvement and to allow service connections to be made to said extensions or additions without liability on • the part of the City. (4.) The properties, the owners of which are to be charged for tapping into or hooking onto the Springbrook Line, and the amount and rate of said charges for said properties, have already been determined in accordance with Ordinance. No. 2847 of the City of Renton. Of the properties involved in this Agreement, they are the properties, sewer service to which is to be provided by the City and not by the District under this Agreement. (5.) The City is presently providing sewer service to Lots 1 and 2 of Scott's Terrace by means of the existing crossing. (6.) No formal agreement for the provision of sewer service in the subject area has been entered into between the City and • the District. (7.) The City also proposes to provide sewer service to • Lots 4 and 5 of Scott's Terrace by permitting the construction of the proposed crossing. (8.) The City is prepared to furnish sewer 'service through the Springbrook Line to Lots 3, 6, 7 and 8 of Scott 's Terrace. (9.) Although all of Scott's Terrace and the Radovich Property are within the Cascade Sewer District and are outside the limits of the City, each party recognizes that sewer service to Lots 1, 2, 3, 4, 5, 6, Y7, 8 and 16 of Scott's Terrace and to that portion -3-• i .' of the Radovich property which lies to the west of the southerly prolongation of the westerly boundary of Lots 17 and 18 of Scott's Terrace can be provided by the City through the Talbot Road Line sooner than such service could be pro- vided by the District, and that sewer service to these prop- erties by the City and the payment to the City of the charges necessary under the Safecare-Careag'e Contract as already de- H termined pursuant to said Ordinance No. 2847 has and will pro- vide the funds for reimbursement of Safecare-Careage under the contract. i (10.) The District proposes to serve the properties within i U.L. I .D. 11 by utilizing the existing crossing and the proposed crossing as hereinabove defined. (11.) Both the City and the District have identical agree- ments with METRO relating to the METRO Line, permitting both the City and the District to make sewer service available to • properties along said line by allowing said properties to be hooked onto the METRO Line, making an appropriate charge to the owners of said properties and remitting the same to METRO as payment against the cost of the construction of said line. (12.) Because of the possible duplication of charges, and • the question of the proper agency to'provide sewer service to various properties referred to above, the parties hereto do desire by this Agreement to formalize their mutual responsibil- ities and rights in the area. MUTUAL COVENANTS AND AGREEMENTS In consideration of the covenants herein contained, and in consideration of the benefits to each of the parties to be derived from this Agreement and the performance thereof, and 1 -4- • _A because of the facts stated above, the parties hereto do agree and covenant as follows: (1.) The City will make sewer service available for that portion of the Radovich Property lying west of the southerly prolongation of the westerly boundary of Lots 17 and 18 of Scott's Terrace and for Lots 1, 2, 3, 4, 5, 6, 7, 8 and 16 of Scott's Terrace, and the District will not attempt to provide sewer service for said areas. ) (2.) The City will authorize an extension of or addition 1 to the Springbrook Line by permitting the construction of the proposed crossing hereinabove defined. Said crossing must be in accordance. with the standards and requirements of the City as to design and construction. The cost of the construction of said proposed crossing will be borne by the District or by private owners with whom the District may contract, or both, but the proposed crossing will be constructed at no cost to the City. (3.) When the proposed crossing is completed, it will be transferred to the City and will be available for the use of the City to provide sewer service to those lots in Scott's Terrace for which the City is to make sewer service available under this Agreement. } (4.) Other than the properties described in Paragraph (1.) of Section III of this Agreement, the District will make sewer service available for all other properties within its boundaries in the area of U.L.I.D. 11. (5.) The City agrees that the District may, without pay- ment of any area connection charges, connection fees, latecomer fees, extended service fees, or any fee of any kind, but at the District's own cost of construction, connect its mains to the existing crossing to the proposed crossing when constructed, provided that the design and construction of the District's -5- facility so connected meet with the approval of the City. (6.) Without any cost to the City, the District will • place a manhole at the easterly end of the existing crossing and will connect the existing side-sewer to this manhole. The District will also cause a manhole to be constructed at the easterly end of the proposed crossing, and each of said manholes, when completed, will be transferred to the City to own as part of their main extensions consisting of the existing cros- sing and the .proposed crossing. Said manholes will meet the design and construction requirements of the City. (7.) Unless it has the prior consent of the City, the District will not attempt to make sewer service available to those properties lying immediately south of So. 180th Street and in the immediate vicinity of the Sringbrook Line which, without the construction of main extensions which would be exempt from any charges under Paragraph 5 of the Safecare- Careage Contract, can be served by that portion of the Spring- brook Line as presently constructed. (8.) Although portions of the lines hereinabove described will be jointly used by the City and the District, each of Ithe parties hereto will maintain its own lines at its own cost. • (9•) If all of the properties which are to be served by the District under this Agreement are annexed to and become a part of the City, the District will, without charge to the City, transfer to the City the entire sewer system to be con- structed by the District in U.L.I.D. 11 as described in this Agreement. (10.) All facilities constructed by the District which are to be transferred to the City under this Agreement will be transferred by an appropriate Bill of Sale in standard form. (11.) The District will hold the City harmless from any • -6- claims made against the City and will protect the City from • any liabilities in connection with any of the work to be done by the District. • (12.) Nothing in this Agreement as to which party shall pro- vide sewer service to particular properties shall be construed as to require the provision of such service except in accord- ance with the Ordinances ,or Resolutions of the party, and • upon payment to the party of all proper charges by the property owner. • IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their duly authorized officers and to have their respective seals affixed hereunto.

The District will pay for all such construction work within the boundaries'of the District, plus the difference between the cost of an 8-inch line and whatever size line is constructed on City property, it being agreed that the larger line is for District's benefit. The cost of such oversizing will be determined by the difference between responsible low bids for -con- structing an 8-inch and the larger size line within City's Local Improvement District. City will bill District the costs for which District is responsible herein. District will pay said billings to the Director of Finance, City Hall, City of Renton, Washington on or before the end of the month during which District has had possession of any such billing by the second Monday thereof (it being under- stood that vouchers for payment of monthly District liabilities are considered for approval by District's Board of Commissioners at their regular meetings on the second Wednesday of each month.)

City assumes the responsibility for measuring total daily gallonage in the line and to .promptly notify District when said line exceeds its capacity. • 11. It is further anticipated that the total cost of said construction to be' borne by District, as hereinabove set forth, is approximately $120,000. 00 less any monies made available from • Federal and State grants; City agrees to advise District of any substantial change in said estimate. District further warrants that proper funds have been budgeted by District for payment of the aforementioned improvements within its boundaries and that District has lawful right to make such payments unto City as hereinabove set forth. A portion of all governmental grant funds received by City in connection with construction of said line shall be credited by City to the District' s obligations hereunder in the ratio which District' s share of the cost of the line bears to the total cost of the project. District will be promptly notified of the receipt of said funds and of the amount thereof to be credited to District. Such credits will be promptly applied by City against District' s liabilities hereunder until exhausted. If application of such credit results in an overpayment by District, City will promptly reimburse District accordingly. . 12. Each of the parties hereby agrees, in order to effectuate • the termsof this Agreement, to execute and deliver unto the other, whenever reasonably necessary, appropriate permits, easements and like documents, and to co-operate with the other to assist in compliance with the Washington Inter-Local Co-operation Act (RCW 39. 34 et seq) and/or any other laws applicable to the parties or the subject matter. • 13.

Rehab Existinn Sanitary Sewer • • TABLE 2 CONSIDERATIONS ON SELECTION OF PIPE MATERIALS The following considerations are to be used in conjunction with Table 1 for tentative selection of pipe materials. a. Rubber gaskets may be severely damaged by petroleum products, particularly in prolonged exposures to concentrated flows containing little or no storm water ' or sanitary sewage. b. Gasketed joints are not considered leak-proof at zero or low pressures, and may not be leak-proof at higher pressures. c. Mechanical joints may be less likely to leak at low pressures than push-on joints. d. May need protective coatings and/or cathodic protection against external corrosion. e. Considered most reliable gasket and lining material for ductile iron leachate pipeline. f. Very difficult to repair linings on inside of joints in pipe smaller than 24-inch diameter. g. Almost always needs protectivecoatings and cathodic 1 protection against external corrosion. h. Properly made joints are considered leak-proof. i. Polyethylene, although corrosion resistant, can be severely affected by prolonged exposures to petroleum products. j . Viton (or nitrile) gaskets may require long delivery time. k. Concrete pipe not recommended without "liquid-tight" liningof another material. real. 1. Potential to develop leaks at joints due to structural or gasket failures. m. Limited to low pressure applications. n. Pipe not available over 15-inch diameter. o. Requires special attention to bedding and backfill depth to avoid structural failure of pipe. p.. Large thermal expansion coefficient. Mayneed to limit mit solvent welded joints to 4-inch and smaller pipe. May • require careful evaluation of pipe installation temperature and temperature of piped liquids to ensure joint integrity. • q. Pipe not available over 12-inch diameter. r. Insituform lining is available in 6-inch through 60-inch diameter for almost any pressure, if sufficient pipe cross-sectional area is available s-u. Not used. v. Suitability of pipe lining and gasket material to resist chemical attack by conveyed fluids must be determined for each pipeline service considered. w. All storm and sanitary sewer manholes, catch basins, and inlets should be equipped with precast concrete bottom and sidewalls with. rubber gasketed joints between sections, water-tight epoxy grout pipe entrances through walls, and bitumastic coating of all interior floor and wall surfaces. Manholes, catch basins, and inlets should have no leakage when hydrostatically tested at , atmospheric pressure. x. Has good resistance to chemicals, petroleum products, and hydrogen sulfide corrosion. y. Not recommended for buried applications due to limited experience and high cost. z. "Zero leakage" test requirement may be impossible to achieve under the best conditions for any pipe material because trapped air may distort test results, even in a drop-tight pipe. Pressure and leakage test requirements should consider whether the pipe has steep slope or will stand full of liquid. Pipelines should be tested with the intent to prevent or minimize leakage. Air testing should not be allowed; hydrostatic testing should beas stringent as any found in the industry. • Pipe materials, without regard for chemical attack, corrosion, or puncture, are generally ranked as follows, in decreasing order of liquid-tight reliability: welded steel with welded joints high density polyethylene with thermal-fusion `, joints PVC with solvent welded joints fiberglass with welded joints Insituform liner .__. ductile iron with viton or rubber gaskets concrete cylinder with gasketed joints welded steel with rubber gasketed joints PVC with viton or rubber gasketed joints concrete pipe with rubber gasketed joints 8-701 8-702 "Side Sewer" shall mean that portion of the public sewer between primary collection lines and individual property lines. "Infiltration and Inflow" shall mean the combined volume of both infiltration and inflow water found in existingsewer systems. "Infiltration" shall mean the volume of water or ground water entering sewers and - building sewer connections from the soil through defective joints, broken or cracked pipe, improper connections or other structural failures. "Inflow" shall mean the volume of water discharged into sewer lines from surface sources such as roof drains, cellar and yard area drains, foundation drains, swamp and spring water drains, and all other accidental or deliberate discharges of surface water. "FWPCA" shall mean the Federal Water Pollution Control Act of 1956, PL 84-660, together with the Amendments of 1966, 1972, and as same may be hereafter amended; Public Law 92-500 and all subsequent amendments thereto.

Such installment contracts shall provide that any unpaid balance may be paid in full in any year at the time the first quarterly payment of such year is due and payable, shall describe the property served by the water, and shall be duly acknowledged by the property owner and be recorded by the Public Works Director in the office of the County Auditor at the expense of such property owner. Delinquent payments under such installment contracts shall be a lien • upon the described property as provided for in RCW 35.67.200, and_ enforceable in accordance with RCW 35.67.220 through 35.67.280. As an additional and concurrent method of enforcing such lien, the water service to such property may be disconnected in accordance with RCW 35.67.290 and this Code- until such time as all delinquent payments have been paid in full. Upon full payment of such installment contract, the Public Works Director, on behalf of the City of Renton, shall execute and deliver unto the-property owner a release of such lien, which shall be recorded, at the expense of the property - owner, with the King County Auditor's office. All installment payments so made shall be applied first to interest accrued up to date, and the balance to principal. (B) In addition to sewer connection permit fees as required by ordinance and the rules and regulations promulgated thereunder, there is hereby imposed upon, and the owners of properties which have not previously been assessed or charged or borne an equitable share of the cost of the City's sewer distribution system shall pay, prior to any connection to a City sewer main, one or more of four (4) special connection charges, herein defined, in an amount to be computed under the following paragraphs of this Section. 1. Latecomer Fees. The imposition, collection, payment, and other specifics concerning this charge are dealt with elsewhere in this Code. 2. Special Assessment Charge. The special assessment charge is a charge for the historical costs for the sewer collection system, which system shall include the sewer collection mains that lie adjacent to or near properties that would behefit directly therefrom, that were not installed by L.I.D.'s or by a private developer under a latecomer agreement. 589 8-717 8-717 B,2) (a) The number of units of property frontage to be served bythe sewer P P Y 9e distribution system, determined in the manner prescribed in RCW 3.5.44.030.040 and .047 for determining "assessable units of frontage", shall be multiplied by the actual local improvement assessment per unit of frontage for such facility for the year in which the sewer main to which the property is to be connected was constructed and accepted as complete by_the City. (b) In addition to the aforestated cost of "assessment" there shall be a charge of ten percent (10%) per annum added to such cost, but in no case shall such charge be in excess of one hundred fifty percent (150%) of the original assessment cost. Interest charges should be simple interest and not compound interest. (c) Such special connection charge for property abutting on a street in which a sewer can be constructed or extended to serve such property but can be connected without actual construction or extension, shall be,computed as if the sewer was so constructed or extended; and the special connection charge for property located back from the margin of the street in which the sewer exists and outside the assessment district created therefor shall be made giving consideration to the distance of said property from the street margin. In no case shall credit be allowed for the cost of extra length of side sewer required for connection to the City's sewerage system; provided, however, that in cases where application of the foregoing formula to a particular parcel of property results in a charge, which because of unusual conditions, or conditions peculiar to said property only, is in excess of charges to similar properties, the Public Works Director is authorized to reduce the special connection charge to such an amount charged to properties similarly situated. 3. Special Utility Connection Charge. The special utility connection charge which shall be assessed against any property which has not participated in the development of the sewer system, which system shall include lift stations, force mains, interceptors and other collection mains, shall be assessed at the rate of: (a) Three hundred dollars ($300.00) per single-family residence and mobile home dwelling; -� (b) One hundred seventy five dollars ($175.00) per living unit of an apartment, condominium, cooperative rental, time-share, motel, hotel, or similar multi-family occupancy residential structure; ,1 (c) For all other properties except City properties, four cents ($.04) per square foot of property connected but not less than three hundred dollars ($300.00); , (d) Fees are incurred upon the granting by the City of a building permit, but are payable at the time construction inspection permits are issued for public sewer extension. All other sanitary sewer service applicants shall pay these fees at the time of building sewer application; -J 589 8-717 8-717 • B,3) (e) Fees are due immediately, notwithstanding the prior paragraph, if the party owing the fee sells to a third party, unless the third party agrees to pay the charge, in writing, with the amount owing to the City set forth in that writing, and further the City agrees that the third party shall be responsible for that fee after determination that such an agreement would be in the City's best interest.. The burden of establishing the agreement would be on the party owing the fee and not on the City, and would be in the City's best interest; (f) When the phrase "property which has not participated in development of the system" is used in this Section, it shall mean property which has not paid a special utility connection charge for the property based upon the square footage of the property that is to be served by the utility. For example, one single-family residence on a five (5) acre tract which has paid three hundred dollars. • ($300.00) under this Section to connect to a sewer system will have paid only for one seven thousand five hundred (7,500) square foot lot at the rate of four cents ($.04). Additional charges would be applied for any additional development on the property. Property that was developed before the effective date of the first connection charge ordinance in 1965 is exempted from the connection charge. Any rebuilding or additions to exempted property that does not require additional water usage .such that a larger domestic meter is necessary will not trigger a new connection charge. However, when property is redeveloped or the use changed or intensified such that a larger domestic water meter or additional domestic water meters are necessary or when no domestic water meter was obtained before, such as property on a well, then any application for the initial water meter or a larger water meter will trigger a utility connection charge. For the purposes of this policy, such property when applying for an initial or larger water meter shall be property that has not been previously assessed. When property is redeveloped and the use intensified such that a four inch (4") (residential) sanitary sewer stub is required to be replaced with a six inch (6") (commercial) sanitary sewer stub, to the sewer main, then any application for __ the sewer construction permit will trigger a utility connection charge. (g) No special utility connection charge will be collected on City-owned properties. The benefits to the utility from the use of other City properties such as utility easements, lift stations, and other benefits offset the amount of the utility connection charge fee; (h) When calculating the area to be charged the connection charge, undeveloped greenbelt and major easements within the property shall not be included in the square footage for the calculation of the charge. When determining whether property is undeveloped greenbelts or major easements, the inquiry should be to recorded easements or dedications or restrictions on the comprehensive plan or zoning maps or City policies that would prevent development or significant usages. This exemption is intended not to charge property that is undevelopable; 589 8-717 8-720 B,3) (i) There shall be no other exemptions from the special utility connection charge. Any party extending utilities that may serve other than the party's property may request a latecomer's agreement from the City. Any party required to oversize utilities may request that the utility participate:in the cost of the project. • 4. Inspection and Approval Fees. In addition to other permits and fees, there will be an inspection/approval fee for on-site and off-site replacement and improvements which shall be identical to that specified in Chapter 8, Title IX and any subsequent amendments thereto. . (C) If any such property for which a special connection charge has been paid later becomes subsequently included in a local improvement district for the construction of a sewer of the same or similar nature, then the principal amount so paid shall be credited to the assessment against such property and such amount shall be paid from the Waterworks Utilities Fund into such Local Improvement District Fund.

'I (B) The public sewer shall be ductile iron, AWWA C 151, cast iron, AWWA C 106, or•C 108, with Type II pushon or Type III mechanical joints, together with cement mortar lining three thirty-seconds inch (3/32") in accordance with AWWA C 104, or polyvinyl chloride (PVC) plastic pipe ASTM D 3034, or concrete nonreinforced ASTM C14 Class 2, or concrete reinforced ASTM C76; rubber gaskets for concrete pipe shall meet ASTM C443 standards; rubber gasket for PVC pipe shall meet ASTM 1869 standards. Minimum size shall be eight inches (8") diameter. 589 j 8-720 8-721 • (C) Manholes shall be installed at the end of each line, at all changes of grade, size or alignment, at distances no greater than four hundred feet (400') for fifteen inch (15") diameter sewers or smaller. Greater spacing may be permitted in larger sewers. Manholes shall be a minimum of forty eight inches (48") diameter, shall be precast concrete or cast in place concrete, with steel reinforcement; steps will be placed at one foot (1') spacing, conforming to current safety regulations. The manhole covers shall be twenty four inches (24") diameter cast iron or aluminum frame and covers. No inside drop connections will be allowed. All connections to the manhole shall match the existing inverts or have an outside drop connection. (D) Lift Stations. All lift stations, both public and for private building sewers shall have alarm and standby emergency operation systems. All lift stations shall meet or exceed the specifications of Chapter 30 of "Recommended Standards for Sewage Works". (E) Comprehensive Sewerage Plan. All public sewer extensions shall conform to the standards and be consistent with the City Comprehensive Sewerage Plan. (F) Public sewers installed in filled or unstable ground, in areas with high ground water levels, or in areas where the potential for infiltration occurs, may be required to be cast or ductile iron pipe, or PVC plastic D-3034 pipe. 8-721: PENALTIES FOR VIOLATIONS OF REGULATIONS: It shall be unlawful for any person to maliciously, knowingly, wilfully or negligently break, damage, destroy, uncover, deface or tamper with any structure, appurtenance or equipment which is part of the City sewage works.

Following our meetings of the past two weeks, we have =r � ;'1- prepared the attached Table 1 which shows Pipeline Material Alternatives for pipelines crossing the City of Renton's Aquifer Protection Area,• Zone 1. The accompanying Table 2 contains a list of considerations which should be evaluated when selecting alternative pipe materials from Table 1. These materials are intended to be used in pipelines carrying storm sewage, sanitary sewage, or landfill leachate. They are not intended for more specialized pipeline service such as transmission of petroleum - ( : products. All materials listed in Table 1 are generally considered suitable for the service indicated, based on accepted practice and their commercial availability. Some materials are better suited than others; however, there is no ., clearcut best choice of pipeline material for a given service. For brevity, the list of suggested material specs does not include the many specifications which cover details such as gaskets, coatings, etc. • It is our understanding that the City will incorporate this list by' reference into the Aquifer Protection Ordinance to provide guidance concerning allowable pipeline materials within Zone 1 of the Aquifer Protection Area, for both new construction and rehabilitation or replacement of existing pipelines.

Our letter of November 21, 1989 did not specifically address use of these materials. Based. on experience of others within CH2M HILL, we recommend that pressure grouts and gels not be used for rehabilitation of storm or sanitary sewers within your aquifer protection area. In our opinion, all of these product applications have only a limited life expectancy, on .the order of five years, and are not a long term solution to ensure the tight sewer leakage requirements . needed in the aquifer area. Further, these product applications, usually installed from inside the pipeline, are more applicable to correcting infiltration problems than to correcting exfiltration problems.
