The purpose of the project is to eliminate a deficit of water storage needed for the 590, 490 and 350 pressure zones of the City's water distribution system. Currently, the quantity of water storage located in these pressure zones does not meet the State of Washington criteria for equalizing, fire and emergency stand-by storage. The project requires Environmental (SEPA) Review and Administrative Site Plan Approval. The water tank would be located on the Rolling Hills Reservoir site. The site is currently occupied by an existing 300,000-gallon elevated reservoir and is also used for the storage of sand stockpiles used by the City. The proposed tank would be located adjacent to the existing elevated reservoir. Access to the site is provided directly off Puget Drive Southeast. The project includes the construction of a 2,099 square foot pump station, along with an emergency electrical generator, to be located north of the proposed tank. A double walled, 550-gallon, above ground diesel fuel tank for the generator engine is proposed next to the building. In addition, the installation of 1,387 linear feet of water lines, 594 linear feet of sanitary sewer lines, 1,457 linear feet of drain lines, 3,051 square yards of crushed gravel for driveways and paths and 1,000 linear feet of 8-foot high security fencing is proposed. Also included with the project is the construction of a bermed containment area and storm water detention pond to be located west of the tank. The majority of the site is heavily vegetated with trees and shrubbery. The project would require the removal of trees and ground cover on the north side of the site, with the southern portion of the site to remain undisturbed. Approximately 15,864 cubic yards of soil would be cut for the construction of the reservoir and building foundations, roadways and paths, and detention pond. The project also includes the restoration of grass areas disturbed by the development. PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21 C.240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: (1) Earth Impacts: The western two-thirds of the site, where the project will be constructed, has an average slope of 4.5%. The eastern portion of the property, which will remain undisturbed, contains slopes of up to 30%. There is an existing 300,000-gallon elevated water storage tank on the site. The remainder of the property is vegetated with relatively thick brush and small to moderate sized deciduous trees. The development of the site would require the removal of some grasses and shrubbery and approximately 170 on-site trees, including Alders, Firs and Maples ranging from 8- inches to 36-inches in size. The project would retain trees along the periphery of the site as well as on the southern portion of the property. The project would also require on-site grading of approximately 15,864 cubic yards of soil for the construction of the reservoir and building foundations, roadways and paths, and detention pond. Approximately 2,146 cubic yards of this material would be utilized on-site for the construction of the berms. The net amount of material to be hauled off-site would be approximately 13,718 cubic yards. Approximately 1,600 cubic yards of aggregates and select fill would be imported for use in utility trench back fill, foundations, roadways, pathways and drainage siteerc ! . City of Renton P/B/PW Department Administrative Site Plan Approval&Environn I Review Committee Staff Report ROLLING HILLS RESERVOIR LUA-99-119,SA-A, ECF REPORT AND DECISION OF SEPTEMBER 28, 1999 Page 3 of 7 ways, in addition to approximately 2,800 cubic yards to be imported for topsoil. The project includes the restoration of grass areas disturbed by the development. A geotechnical report for the proposal, prepared by GeoEngineers, Inc., dated March 22, 1996, was submitted with the application. Based on site explorations, the site is underlain by loose to medium dense brown silty fine sand with a trace of gravel. The geotechnical consultant concludes that these conditions are suitable for support of the structures as proposed, provided recommendations presented in the geotechnical report are incorporated into the earthwork and foundation preparation. Staff recommends that the applicant be required to follow the recommendations contained within the geotechnical report in order to mitigate potential impacts from the development. Potential erosion impacts that could occur during construction would be mitigated by City Code requirements for an approved Temporary Erosion and Sedimentation Control Plan (TESCP) and Construction Mitigation Plan prior to issuance of Construction Permits. Mitigation Measures: The applicant shall follow the recommendations of the Geotechnical Engineering Report, dated March 22, 1996, prepared by GeoEngineers, Inc., regarding site preparation, general earthwork and design criteria. Policy Nexus: Environmental Ordinance (SEPA) (2) Water Impacts: A drainage report for the proposal, prepared by RH2 Engineering, dated August 10, 1999, was submitted with the application. According to the report, there is no evidence of channelized flow or streams on the site. There is an existing drainage swale located along the northeast property line and along Puget Drive Southeast. The construction of the proposal would result in 3% impervious surface lot coverage of the 12.97-acre site. The project would be exempt from providing on-site peak rate runoff control due to negligible peak runoff rate increases. Because the project site is located outside of the City's Aquifer Protection Area and would not be subject to vehicular access other than infrequent maintenance visits, no water quality treatment is proposed. Included with the proposal is the construction of a bermed containment area capable of retaining 100% of the reservoir volume in the unlikely event of tank rupture. The containment area would also be utilized for emergency overflows, maintenance drainage and storm water runoff. Runoff from the tank roof, perimeter road and pump station would be collected in storm water drainpipes and discharged into the containment area. The storm water detention pond includes a flow control structure, which discharges to an existing 12-inch storm drain line located in 116th Avenue Southeast. Mitigation Measures: No further mitigation is recommended. Policy Nexus: N/A B. Recommendation Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials make the following Environmental Determination: DETERMINATION OF XX DETERMINATION OF NON-SIGNIFICANCE NON- SIGNIFICANCE- MITIGATED. Issue DNS with 14 da A eal Period. XX Issue DNS-M with 14 day Appeal Period.

Consistency with Site Plan Criteria In reviewing the proposal with respect to the Site Plan Approval Criteria set forth in 4-9-200E of the Site Plan Ordinance, the following issues have been identified by City Departmental Reviewers and Divisional Reviewers: 1. Conformance with the comprehensive plan, its elements and policies; The subject site is designated Residential Single Family on the City's Comprehensive Plan Land Use Map. The proposed utility is consistent with the following Objectives and Policies contained within the Utility Element of the Comprehensive Plan. siteerc City of Renton P/B/PW Department Administrative Site Plan Approval&Environs it Review Committee Staff Report ROLLING HILLS RESERVOIR LUA-99-119, SA-A,ECF REPORT AND DECISION OF SEPTEMBER 28, 1999 Page 5 of 7 Objective U-B. Provide and maintain safe, reliable and adequate utility facilities and services for the city's current and future service area to meet peak anticipated demands of the City in an efficient, economic and environmentally responsible manner. Policy U-5. Encourage the appropriate siting, construction, operation, and decommissioning of all utility systems in a manner that reasonably minimizes impacts on adjacent land uses. The proposal is intended to eliminate a deficit of water storage needed for the 590, 490 and 350 pressure zones of the City's water distribution system. Currently, the quantity of storage within these pressure zones does not meet the State of Washington criteria for equalizing, fire and emergency stand-by storage. In addition, the proposed location of the facility allows for the higher utilization of a site currently used by the City for reservoir purposes and eliminates the need for siting the facility in another location where impacts may be greater. The site is sufficiently screened by existing vegetation and the proposal would not negatively impact surrounding properties or uses. 2. Conformance with existing land use regulations; The subject site is designated as Public Use (P-1) on the City's Zoning Map. All projects located in the P-1 zone require site plan review. "Municipal utility facilities" are considered primary permitted uses in this zone. The proposal's compliance with the applicable development standards of the P-1 zone is discussed below. Setbacks/Landscaping — The P-1 zone requires a minimum front yard/street setback of 20 feet, a rear yard setback of 10 feet, and an interior side yard setback of 5 feet. When located adjacent to parcels designated as single family, a minimum setback of 50 feet is required. At least 20 feet of the front setback must be landscaped. The proposed pump station and tank would each have setbacks greater than 60 feet from the closest property line — satisfying all setback requirements. In addition, the project would retain the existing vegetation along the front property lines, maintaining the required 20-foot landscaped setback. Grass areas disturbed by the development would be restored as part of the project. Height — The maximum height permitted in the P-1 zone is 50 feet. The water tank is proposed at a height of 45 feet and the pump station is proposed at a height approximately 12 feet— both of which are below the maximum allowed. Parking/Access —The P-1 zone requires the principal access to the site be provided from an arterial or collector street. The proposed access points to the site (2 total) would be directly off Puget Drive Southeast, which is designated as a minor arterial on the City's street classification system. Access to the site would be gated and an 8-foot high chain link fence would secure the perimeter. Maintenance visits to the site would be infrequent and would not generate the need for parking spaces. Therefore, the parking regulations are not applicable to the proposal. 3. Mitigation of impacts to surrounding properties and uses; The proposal would be located on a site currently utilized by the City for water reservoir purposes. The proposed water tank would not create significant impacts above the current use of the site. Therefore, impacts to surrounding properties would be minimal. The perimeter of the site is sufficiently vegetated to provide adequate visual screening of the proposed reservoir. In addition, the project includes the construction of a bermed containment area capable of retaining 100% of the reservoir volume in the unlikely event of tank rupture, thereby eliminating any potential hazards from the proposal to the surrounding uses. Potential short-term noise and traffic impacts would result from the initial construction of the project to adjacent residents. These impacts would be mitigated by the proposed hours of construction (8:00 am to 5:00 pm, Monday through Friday) as indicated in the applicant's construction mitigation plan. siteerc City of Renton P/B/PW Department Administrative Site Plan Approval&Environn it Review Committee Staff Report • ROLLING HILLS RESERVOIR LUA-99-119,SA-A, ECF REPORT AND DECISION OF SEPTEMBER 28, 1999 Page 6 of 7 4. Mitigation of impacts of the proposed site plan to the site; The proposal is not expected to adversely impact the site. There are no significant natural or human-made features on the property that would be impacted by the proposal. Construction activities related to the initial development of the project would be required to utilize best management practices through code requirements for an approved Temporary Erosion and Sedimentation Control Plan (TESCP). 5. Conservation of area-wide property values; The proposal would allow for the City to achieve compliance with State requirements for water equalizing, fire and emergency stand-by storage in the 590, 490 and 350 pressure zones. Therefore, the project would be likely to conserve property values in the area. 6. Safety and efficiency of vehicle and pedestrian circulation; The proposal would not increase the current number of trips to the site and would not be subject to the parking regulations. Locked gates at each of the entrances to the site would prohibit unauthorized access to the site. As proposed, the driveway and gravel roadways appear to be of adequate width for the safe circulation of maintenance and emergency vehicles through the site. 7. Provision of adequate light and air; The proposed structures would allow for adequate light and air circulation to the site. 8. Mitigation of noise, odors and other harmful or unhealthy conditions; The proposal is not anticipated to create any harmful or unhealthy conditions. Noise and odor impacts in the vicinity would not have a significant increase due to the proposed development. The applicant's Temporary Erosion and Sediment Control Plan (TESCP) and Construction Mitigation Plan would mitigate noise, dust and odors, which may result from the temporary construction of the project. 9. Availability of public services and facilities to accommodate the proposed use; and Existing public services and facilities adequately serve the subject site. The project includes the installation of water, sanitary sewer and drainage lines, but would not require the extension of services or further improvements. 10. Prevention of neighborhood deterioration and blight. No deterioration or blight is expected to occur as a result of the proposal. XX Copies of all Review Comments are contained in the Official File.

Water Utility Engineer cc: Gregg Zimmerman Lys Hornsby Abdoul Gafour Leslie Nishihira 1055 South� Grady Way- Renton, Washington 98055 i�F1)This oaoer contains 509,recycled material,20%post consumer PROJECT NARRATIVE Project W-2230 CONSTRUCT ROLLING HILLS RESERVOIR AND BOOSTER PUMP STATION 2401PUGET DRIVE SE Project Purpose. The purpose of the proposed project is to eliminate a deficit of water storage needed for the 590,490 and 350 pressure zones of the City's water distribution system. Currently,the quantity of storage located in these pressure zones does not meet State of Washington criteria for equalizing, fire and emergency stand-by storage. Proposed Improvement Scope. The proposed project includes the construction of a three million gallon water storage tank and a 2,099 square foot, single story booster pump station. The proposed construction will be on a 12.97 acre, City owned site at 2400 Puget Drive SE. The proposed above ground, steel reservoir will be 119 feet in diameter and 45 feet high. The booster pump station building will have concrete masonry walls and a standing seam metal roof on wood framing. The booster pump station will include an emergency electrical generator. A double walled, 550 gallon, above ground, storage tank for diesel fuel for the generator engine will be located adjacent to the building. The work is immediately adjacent to the existing 300,000 gallon elevated Rolling Hills reservoir located on the same site. The project also includes 1,387 linear feet of water line of which 180 linear feet will be within right-of-way; 594 linear feet of sanitary sewer line of which 70 linear feet will be within right-of-way; 1,457 linear feet of drain lines; 3051 square yards of crushed stone driveways and paths; a bermed containment area and storm water detention pond; approximately 16,900 square yards of graded, topsoiled and seeded areas; and 1,000 linear feet of 8 ft. high security fence. No off-site improvements are proposed. After construction approximately 3 per cent of the parcel will be covered with impervious surfaces. The site soils are silty sand with gravel and occasional cobbles. There is no evidence of channelized flow or streams on this site. The peak runoff increase for this project for the 24-hour, 100-year event is less than 0.5 cfs. Approximately 15,864 cubic yards of soil will be cut for the construction of the reservoir and building foundations, roadways and paths, and detention pond. The berms will require 2,146 cubic yards of native material with 2,146 cubic yards coming from on-site excavation. The net amount of material being hauled off the site will be 13,718 cubic yards. Approximately 1,600 cubic yards of aggregates and select fill will be hauled to the site for use in utility trench back fill, foundations, roadways, pathways and drainage ways. The volume of imported topsoil will be approximately 2,800 cubic yards. The following types, sizes and numbers of trees will be removed: Alder: 8" — 33 each, 9" — 1 each, 10"— 18 each, 11"— 1 each, 12"—30 each, 13"— 1 each, 14"— 14 each, 18"—2 each, 22"— 1 each, and 24"— 1 each; Fir: 8"—4 each, 9"—2 each, 10"—2 each, 12"—8 each, 14"— 5 each, and 16"—2 each; Maple: 8"—4 each, 10"—4 each, 12 inch— 3 each, 14" — 5 each, 16" —3 each, 18" — 8 each, 20"—6 each, 21"— 1 each, 22"—2 each, 24"—3 each, 26"—3 each, 28"— 1 each, 33"— 1 each and 36"— 1 each. Miscellaneous brush and grass will be removed over a 3.7 acre area. Current Use of Site. The site is zoned as P-1, Public Use. Adjacent properties are zoned R-8, Residential (eight units per acre). Currently the site is used for a 300,000 gallon elevated water tank for the City's drinking water distribution system and for storage of sand used by the Public Works Department's street crews. Adjacent properties: to the northwest and north are the Bonneville Power Authority's switch yard and transmission lines, to the northeast and east are single family residences (Tiffany Park and Ponderosa Estates), to the southeast is a church (United Christian Church), to the south and southwest are single family residences (Rolling Hills Village No. 3) and to the west are multi-family residences(Rolling Hills Village)..

Nishihira Cc: Abdoul Gafour; Lys Hornsby; Thomas G. Boyns Subject: Rolling Hills Title Report Date: Tuesday, August 31, 1999 2:26PM Priority: High Jennefer / Leslie: The title report provided by Pacific Northwest Title to the Water Utility for the Rolling Hills property is incorrect. They missed the Warranty Deed (#5967605) which transferred the property to the City. The tile company has been notified and said it will be providing a new title report. FYI: A warranty deed transferred the 1 2.97 acres from Puget Western to the City of Renton on 18 November 1965. (King County file # 5967605). On 18 October 1983 the eastern 30 feet were transferred from Puget Western to the City of Renton via a quit claim deed (King County file # 8310280600). Please proceed with processing the SEPA and Site Approval Application. I will provide you with the replacement (corrected) title report as soon as I receive it from Pacific NW Title. Thanks. J.D.

The purpose of the proposed project is to eliminate a deficit of water storage needed for the 590, 490 and 350 pressure zones of the City's water distribution system. Currently, the quantity of storage located in these pressure zones does not meet State of Washington criteria for equalizing, fire and emergency stand-by storage. Proposed Improvement Scope. The proposed project includes the construction of a three million gallon water storage tank and a 2,099 square foot, single story booster pump station. The proposed construction will be on a 12.97 acre, City owned site at 2400 Puget Drive SE. The proposed above ground, steel reservoir will be 119 feet in diameter and 45 feet high. The booster pump station building will have concrete masonry walls and a standing seam metal roof on wood framing. The booster pump station will include an emergency electrical generator. A double walled, 550 gallon, above ground, storage tank for diesel fuel for the generator engine will be located adjacent to the building. The work is immediately adjacent to the existing 300,000 gallon elevated Rolling Hills reservoir located on the same site. The project also includes 1,387 linear feet of water line of which 180 linear feet will be within right-of-way; 594 linear feet of sanitary sewer line of which 70 linear feet will be within right-of-way; 1,457 linear feet of drain lines; 3051 square yards of crushed stone driveways and paths; a bermed containment area and storm water detention pond; approximately 16,900 square yards of graded, topsoiled and seeded areas; and 1,000 linear feet of 8 ft. high security fence. No off-site improvements are proposed. After construction approximately 3 per cent of the parcel will be covered with impervious surfaces. The site soils are silty sand with gravel and occasional cobbles. There is no evidence of channelized flow or streams on this site. The peak runoff increase for this project for the 24-hour, 100-year event is less than 0.5 cfs. Approximately 15,864 cubic yards of soil will be cut for the construction of the reservoir and building foundations, roadways and paths, and detention pond. The berms will require 2,146 cubic yards of native material with 2,146 cubic yards coming from on-site excavation. The net amount of material being hauled off the site will be 13,718 cubic yards. Approximately 1,600 cubic yards of aggregates and select fill will be hauled to the site for use in utility trench back fill, foundations, roadways, pathways and drainage ways. The volume of imported topsoil will be approximately 2,800 cubic yards. The following types, sizes and numbers of trees will be removed: Alder: 8" — 33 each, 9" — 1 each, 10"— 18 each, 11"— 1 each, 12"—30 each, 13"— 1 each, 14"— 14 each, 18"—2 each, 22"— 1 each, and 24"— 1 each; Fir: 8"—4 each, 9"—2 each, 10"—2 each, 12"—8 each, 14"— 5 each, and 16"—2 each; Maple: 8"—4 each, 10" —4 each, 12 inch— 3 each, 14" — 5 each, 16" — 3 each, 18" — 8 each, 20"—6 each, 21"— 1 each, 22"—2 each, 24"—3 each, 26"—3 each, 28"— 1 each, 33"— 1 each and 36"— 1 each. Miscellaneous brush and grass will be removed over a 3.7 acre area. Current Use of Site. The site is zoned as P-1, Public Use. Adjacent properties are zoned R-8, Residential (eight units per acre). Currently the site is used for a 300,000 gallon elevated water tank for the City's drinking water distribution system and for storage of sand used by the Public Works Department's street crews. Adjacent properties: to the northwest and north are the Bonneville Power Authority's switch yard and transmission lines, to the northeast and east are single family residences (Tiffany Park and Ponderosa Estates), to the southeast is a church (United Christian Church), to the south and southwest are single family residences (Rolling Hills Village No. 3) and to the west are multi-family residences(Rolling Hills Village)..

C/ ENT p LA RFN oN••s 1G AUG 1959 CITY OF RENTON ENVIRONMENTAL CHECKLIST PURPOSE OF CHECKLIST: The State Environmental Policy Act (SEPA), Chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. 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. ,r-1 Onl+^ENT Pt-- D ' CITY OF REN-i Li'v A.

' The site is located south and west of the intersection of Puget Drive Southeast and Edmonds Avenue Southeast, as shown on the Site Plan, Figure 1. GeoEngineers presented the results of our Phase I and II portions of the site study in our "Report, Geotechnical Engineering Services,Proposed Rolling Hills Reservoir and Booster Pump Station, Renton, Washington" dated April 13, 1988. Our Phase I study included an evaluation of the historical mining hazard and fault/earthquake hazard and the Phase II study presented the 1 results of specific foundation explorations and design and construction recommendations. • We understand that the proposed project will consist of constructing two water storage tanks, each with a 4-million-gallon capacity. The tanks are expected to be about 40 feet high with their base at Elevation 453 and overflow at Elevation 490. The tanks will be about 130 feet in diameter and be constructed as at-grade steel structures. We also understand that the south j tank shown on our site plan will be constructed at this time and the other tank in the future. A 1 booster pump station will be located adjacent to the new tanks and will pump to the city's existing elevated tank located on the site. . IL- . SCOPE .The purpose of our services for this phase of the project is to provide geotechnical design r • . : . recommendations based on the subsurface soil and ground water information obtained during our 1988 P study. The s ecif c scope of our services consists of the following tasks: 1 1. Attend one meeting with representatives of RH2 Engineering to discuss the design elements I , . for the project. . _-. 2. Review available soil and ground water information obtained during our previous study and i for nearby studies. • 3. Review information and describe the risks associated with previously identified potential geologic hazards at the site. . • 4. Describe and characterize soil and ground water conditions at the site. J. I 11 File No.0693-044 02-1130/032296 G c o E n g in e e r s 5. Provide recommendations for site preparation and earthwork including estimated stripping ` depths, use of on-site soil for structural fill and trench backfill, and requirements for imported fill.

SITE CONDITIONS GENERAL GeoEngineers completed an assessment of geologic hazards in the project area as part of _ our 1988 study. The results of that study and comments regarding studies and information available since then pertaining to potential geologic hazards is provided in Appendix B. The summary in Appendix B pertains to both coal mine and seismic hazards. Based on our review . and recent research, it is our opinion that there is a low risk of hazard from the presence of deep coal mines below the site. The "Conclusions and Recommendations" section of this report provides our recommendations for reducing seismic risks. SURFACE CONDITIONS " The site is approximately 10 acres in area, with current development limited to the city of Renton's existing elevated water-tank. We noted several minor excavations or areas of ground : modification during our site reconnaissance and field exploration program as part of our previous :study. The site has been logged at least once with only, scattered evergreen trees remaining. Most of the site is covered with relatively thick brush and small- to moderate-sized deciduous • trees. A topographic ridge trends in a generally north to south direction across the site. The east flank of the ridge is a very gentle slope, dropping about 10 feet of elevation in 300 feet. The west flank is a more moderate slope, dropping about 10 feet in 100 feet, and then sloping slightly steeper toward the property boundary. The general site topography is shown in Figure 1. GeoEngineers• • 2 File No.0693-044-02.1130/032296 SUBSURFACE CONDITIONS Subsurface conditions at the project site were evaluated as part of our previous study by excavating eight test pits at the locations shown in Figure 1. A detailed discussion of the exploration procedures and logs of the test pits are presented in Appendix A. The subsurface conditions encountered in our test pits were relatively uniform. An exception was Test Pit 5, which encountered about 1 foot of fill soils with considerable organic matter apparently associated with previous grading performed on the site. The explorations indicate the site is mantled by a layer of forest duff, sod and topsoil up to about 0.5 feet in thickness. Greater depths of organics should be expected in densely vegetated areas. The topsoil generally overlies a variable thickness of loose to medium dense brown silty fine sand with a trace of gravel. Occasional roots were noted in several of the test pits to a depth of about 2 feet. Below a depth which varied from about 3 to 6-1/2 feet of depth, very dense gray silty sand with gravel, occasional cobbles and boulders was encountered in all the test pits. This stratum is referred to geologically as glacial till and has been compressed under the weight of glacial ice. The upper loose to medium dense soils represent the weathered horizon of the glacial till. The subsurface conditions are shown in the Generalized Geologic Cross Sections, Figure 2. The locations of the sections are shown in Figure 1. GROUND WATER CONDITIONS Very slow ground water seepage was observed within a sandy layer of the glacial till in Test Pit 1. Slow ground water seepage was also observed in Test Pit 8 at the bottom of the weathered • horizon. No ground water seepage was observed in any of the other test pits. Fluctuations in ground water conditions should be expected as a result of changes in season, precipitation and other factors. A perched ground water condition likely occurs seasonally at the bottom of the weathered till layer which overlies very dense relatively impermeable unweathered till. Hi • CONCLUSIONS AND RECOMMENDATIONS GENERAL - The two water storage tanks and booster pump station can be constructed on the site as proposed provided site earthwork and foundation preparation is completed as recommended below. The tanks and building footings should be founded on the medium dense to dense native till or properly placed structural fill. i..: SITE PREPARATION AND EARTHWORK The following recommendations apply to all earthwork and structural fill placement and compaction. • Portions of the site where structures or access roads will be located should be stripped of vegetation and topsoil. Based on the explorations, we expect that stripping depths will average about 6 inches. G e o E n g i n e e r s 3 File No.0693-044-02-1130/032296 • Additional stripping depths may be necessary where trees are removed and if the site soils are softened during construction. • • Temporary cuts are expected to encounter weathered and unweathered glacial till. • The exposed subgrade must be compacted to a firm, nonyielding condition prior to placing structural fill or formwork. • For planning purposes, we recommend that temporary cuts into the weathered till be sloped at a maximum of 11/2H:1V (horizontal to vertical) and unweathered till 1H:1V for cuts less than about 8 feet in height. • Sloughing or spalling of either of these zones could occur at these slope angles and some modifications for safety purposes may be necessary. Construction grades should prevent surface water from entering the excavation. Erosion protection such as plastic sheeting should be applied during wet weather conditions. • The native weathered and unweathered till will be suitable for structural fill in roadway • areas, but only if the moisture content can be controlled. We recommend using imported . structural fill for support of tank and building foundations, and floor slabs. • Imported structural fill should consist of sand and gravel containing less than 5 percent fines by weight relative to the fraction of the material passing the 3/4-inch sieve. This imported fill material should be free of rock fragments larger than 6 inches, debris and organic materials. • Structural fill placed in proposed foundation and floor slab areas must be compacted to at least 95 percent of MDD (maximum dry density) (per ASTM D-1557). • • Structural fill placed in utility trenches should be compacted to at least 90 percent, except in any areas to be paved. In these areas the upper 2 feet below finished subgrade must be compacted to at least 95 percent of the same standard. • The site soils possess a high silt content. These soils are easily disturbed during wet - - • weather conditions. We recommend the earthwork be performed during the drier summer • months. Construction traffic should be minimized in the foundation area during wet weather. • It may.be necessary to blanket the glacial till soils with pit run or crushed rock in order to minimize disturbance during wet weather construction activities. It will be necessary to recompact or remove soils loosened or softened during construction as discussed above. Specific erosion/sediment control facilities must be included in the grading design because of high erosion potential of the on-site soils. FOUNDATION CONSIDERATIONS • Water Storage Tanks • The tanks should be supported on a ringwall footing or mat foundation with a thickened edge. G e o E n g i n e e r s 4 File No.0693.044-02-1130/032296 • The foundation should bear on the dense to very dense native till encountered in our test pits. A mud mat should be placed immediately after foundation excavation to protect the subgrade. • Ringwall footings should be at least 18 inches wide and extend at least 18 inches below the lowest adjacent finish grade for frost protection. • Provided the subgrade is prepared as recommended above, an allowable bearing pressure of 5,000 psf(pounds per square foot) may be used for the total of dead and long-term live loads. i • This allowable bearing pressure may be increased by up to one-third for short duration live loads such as those resulting from wind and seismic loads. • We recommend that the floor slab or tank bottom be supported on at least a 6-inch thickness of crushed rock compacted to at least 95 percent MDD. • • All trench backlill within the tank area should consists of imported structural fill, as described above, compacted to at least 95 percent MDD. We estimate that postconstruction settlement of the tank, supported as recommended above, should be less than 1/2 inch under full loading with differential settlem•:nt of less than 1/4 inch. This settlement should be largely completed after the initial full height water test is done. Booster Pump Station • The booster pump station building can be supported on conventional spread footings founded either on the native dense till or on a pad of structural fill. • The zone of structural fill supporting foundation elements should extend laterally beyond the foundation edges a horizontal distance at least equal to the thickness of the structural fill placed. The building footings should be at Ieast 18 inches wide. _ . • • For frost protection,the footings should be founded at least 18 inches below lowest adjacent finished grade. • Footings supported on native subgrade or a structural fill pad extending to the native dense i fill prepared as recommended above can be designed using an allowable bearing pressure • of 3,000 psf for the total of dead and long-term live loads. • This allowable bearing pressure may be increased by up to one-third for short-term live loads such as those resulting from wind or seismic forces. 1 '� ravel containingless than • A base course consisting of at least 4 inches of free-draining gravel 3 percent fines should be placed beneath the floor slab to provide uniform support and a capillary break. • • A vapor barrier such as plastic sheeting may be used to provide added protection against the upward migration of moisture into the floor slab, if appropriate. • A 2-inch-thick layer of sand should be placed over the vapor barrier for protection against damage during concrete placement. G e o E n g i n e e r s 5 File No.0693-044-02-1130/032296 Y We estimate that the postconstruction settlement of both footings and floor slab,,supported 1 as recommended above, will be less than 1/2 inch. Most of this settlement is expected to occur as loads are applied. • Lateral Resistance • Passive resistance should be evaluated using an equivalent fluid density of 350 pcf(pounds per cubic foot) on the sides of the tank ringwall and the pump house footings. This value includes a factor of safety of about 1.5. • Resistance to passive pressure should be calculated from below a depth of 1 foot measured • k from the lowest adjacent ground surface unless the adjacent area is paved. In that case, ,�_; passive resistance can be calculated from the finished pavement surface. • This passive resistance applies where structural fill compacted to at least 95 percent MDD extends outward at least two times the depth of the footing or tank ringwall. • Frictional resistance can be evaluated using 0.4 for the coefficient of base friction against foundation elements. This value includes a factor of safety of about 1.5. We recommend that all footing excavations be evaluated by a representative of our firm immediately before any mud mat structural fill, crushed rock, sand and gravel, steel or concrete is placed, to determine if the work is completed in accordance with our recommendations and that i subsurface conditions are as expected. UTILITY TRENCHES We expect that utility trench excavations will be constructed using conventional open-cut techniques. The following recommendations apply to excavation and bacldill. . • • All shoring and temporary slopes should conform to applicable local, state and federal l • - . safety regulations. * • • - For planning purposes, temporary excavations within the upper layer of weathered till which are iri excess of 4 feet but less than 8 feet in depth should be sloped at no steeper 1 than 11/2H:1V unless lateral support of the trench sides is provided. The portions of temporary excavations within the underlying unweathered till should be sloped at no steeper than 1H:1V. - i • . Ground water seepage, if encountered during excavation, may be controlled by ditching and using sump pumps, as necessary. • Trench backfill may consist of the weathered and unweathered till if adequate compaction can be achieved. If construction takes place during periods of wet weather imported I . . structural fill may be required to achieve adequate compaction. Soil imported for trench backfill should meet the requirements of structural fill presented above. • Backfill placement and compaction should meet the requirements presented above for structural fill. G e o E n g i n e e r s 6 File No.0693-044-02.1130/032296 DRAINAGE CONSIDERATIONS We recommend that a perforated perimeter drain be installed at the footing elevation of the proposed booster pump building and at the bottom of any equipment sumps which extend below footing elevation. A perforated drain should also be placed for the reservoirs if the site grades are such that hydrostatic pressures could develop below the tank bottom. These perforated drains should be collected and routed by a gravity tightline to a suitable discharge point. Provisions should be made for water collected under the bottom of the reservoir to drain into the perimeter drain or other suitable discharge. Surface drainage systems should be installed in conjunction with the proposed booster pump building and water storage tanks. Roof drains should be r� tightlined to a suitable discharge point well away from the tanks and booster pump building. Roof drains must not be discharged at a location or in a manner that water can back up into the footing or subslab drains. The ground surface adjacent to the tanks and building should be sloped to drain away from the structures. . SEISMIC CONSIDERATIONS The project site is located within the Puget Sound region which is a moderately active seismic area. We spoke with Mr. Steve Savage of Coughlin Porter Lundeen (project structural engineers) and understand that water storage tanks are typically designed to resist seismically induced lateral loads by using a pseudo-dynamic design approach in accordance with either the UBC (Uniform Building Code) Section 1632 or AWWA (American Water Works Association) D-100 methodology for steel tank design. Both approaches establish a ground acceleration based • on zonation maps for the United States. According to the 1994 Edition of the Uniform Building Code, the project site is located within Seismic Risk Zone 3 with a Seismic Zone Factor (Z) of 0.30. This zone generally corresponds to a ground acceleration of about 0.30g, where g is the gravitational constant. As defined in'the Uniform Building Code, the site is best classified as a Soil Profile Type Si. This • • . -profile type consists of "dense or stiff soil conditions where the depth of soil exceeds 200 feet." .We also completed a site specific seismic evaluation to determine the ground response -= during an earthquake and the maximum likely ground acceleration for two scenarios: (1) a subduction zone earthquake off the coast of Washington, and (2) an event along the Seattle Fault • which is represented by a series of east-west trending faults which extend through the Seattle area. The site specific evaluation was completed using the SHAKE2 computer program developed by researchers at the University of California, Berkeley. r. Subduction zone earthquakes located along the coast of Washington are thought to be • capable of generating earthquakes of magnitude 8.5 or greater. Earthquakes along the subduction zone are generally located at depths of about 35 kilometers and at a distance of about 150 to 270 kilometers from the site. The energy and magnitude of ground motion for these earthquakes, particularly the moderate to high frequency motions, are generally attenuated (reduced) prior to • reaching the Puget Sound area. Based on our site specific evaluation, it is our opinion that G e o E n g i n e c r s 7 File No.0693-044-02.1130/032296 • ground accelerations of 0.14g to 0.20g may be expected at the site. These accelerations are based on peak bedrock accelerations of 0.09g to 0.13g and the soil conditions at the site. These ground 1-1 accelerations are well within the general range of accelerations applied by the pseudo dynamic l approach of the UBC or AWWA. However, the period of the ground motions will be longer which may develop higher dynamic forces within a tank from the sloshing liquid. A site response spectra is included in Figure 3 for a subduction zone event. The UBC response spectra is also shown in Figure 3. A shallow nearby fault such as the Seattle Fault may result in relatively high ground motions resulting from a moderate magnitude earthquake. The Seattle Fault has been studied and ' evaluated for years. New developments in research indicate that the Seattle Fault is a series of ' four or more east-west trending, south dipping faults which extends from the Kitsap Peninsula to the Cascade foothills. The fault zone passes below the south portion of Elliott Bay and extends i`. east to Issaquah generally along the Interstate 90 corridor. The fault is located about 10 kilometers below the ground surface and about 12 kilometers north of the site. The likely maximum magnitude of earthquakes generated along this fault is about 7 to 7.5. Based on our - site specific evaluation, it is our opinion that around accelerations of 0.60g to 0.80g may occur -_ at the site during a strong earthquake. These accelerations are based on peak bedrock accelerations of 0.40g to 0.57g and the soil conditions at the site. A ground response spectra is presented in Figure 4 for a Seattle Fault event along with the UBC response spectra. 1 Our analysis suggests that relatively high levels of ground shaking will likely occur at the foundation level of the tanks should an earthquake occur along the Seattle Fault or along the subduction zone off the coast of Washington. These two events represent maximum credible earthquakes which implies that the level of ground shaking is never the maximum that can be expected. They are not included in the standard design values contained in the UBC, Zone III t. areas. In addition, the UBC standard for zone III areas is for a period of ground shaking on the order of 30 seconds or less. The subduction zone event.could cause ground shaking which might hi -last two minutes or more. The number of cycles and duration of shaking should be considered - - in the tank design. • We recommend that the structural engineer evaluate the effect that the ground motions ~ • presented herein may have on the structural design of the tank. This can then be compared with :the structural requirements for a standard UBC design. This comparison would allow a cost 1 evaluation of upgrading the tank design to withstand a larger earthquake than the standard UBC i? design earthquake. The city of Renton could then use this information to decide whether they i i,, are willing to pay an additional cost to reduce potential risks during a maximum credible '' - earthquake ROADWAY PAVEMENT DESIGN The following pavement recommendations are based on typical traffic conditions for this type of facility. We expect that much of the traffic will consist of light trucks and that occasional heavy trucks will access the area for maintenance. Very slow vehicle speeds are also assumed. G c o E n g i n e e r s 8 File No.0693-044-02-1130/032296 . I • t. The exposed subgrade in roadway and pavement areas should be prepared as recommended above under "Site Preparation." The subgrade should be proofrolled immediately prior to placing the subbase material. Soft or disturbed areas which develop in the subgrade should be removed and replaced with granular fill compacted as recommended to provide adequate pavement support. We recommend that the pavement section for the access road consist of 2 inches of Class B • asphalt concrete over 4 inches of crushed rock, provided the subgrade is prepared as recommended and that pavement construction is done during a period of extended dry weather. The pavement section presented above is based on having a relatively dry and properly compacted subgrade as defined above on which to place the subbase, base course and paving. All new Class B asphalt concrete pavement materials and placement should generally conform to Section 5-04, WSDOT (Washington State Department of Transportation) 1991 Standard Specifications for Road, Bridge and Municipal Construction. Asphalt concrete should be compacted to at least 92 percent of Rice density. All crushed rock should conform to Section 9- 03.9(3) of the Standard Specifications. The crushed rock and subbase where recommended should each be compacted to at least 95 percent of the maximum dry density determined in tiaccordance with ASTM D-1557. It is important to pavement performance that bacld'ill in utility trenches located in areas to be paved also be compacted as specified for structural fill.

The explorations locations were determined in the field by measuring from survey stakes provided by others indicating the proposed reservoir locations. The elevations were determined based on their location with respect to topographic information presented on a preliminary plan by RH2 Engineering dated 2/4/88. The test pits were excavated to approximately 10 feet of depth using a rubber-tired backhoe under subcontract to our firm. The test pit explorations were continuously monitored by a geotechnical engineer from our firm who maintained a detailed log of the soils encountered, obtained representative soil samples, and observed ground water conditions. Soils encountered were classified in general accordance with the soil classification system shown in Figure A-1. The test pit logs are presented in Figures A-2 through A-4. All soils samples were brought to our laboratory for further examination. Al samples were tested to determine their moisture content which is presented on the logs. 1 -.

APPENDIX B IC:1 SUMMARY OF POTENTIAL GEOLOGIC HAZARDS COAL MINING ACTIVITY GeoEngineers provided the following summary of coal mining activity in our 1988 report. ; No significant research has been completed since then for the project area revealing additional l_ _ details for our summary. t: Similar to many areas in the Renton and South King County vicinity, underground mining l activity occurred below the site in the early 1900s. We performed a literature searc to 10. determine the extent of the coal mining activity that was undertaken below the site. Based on this information, we evaluated the potential hazard this historic mining might pose to the proposed project. A list of selected references is presented in Appendix B. 1 i - - The referenced Morrison/Knudsen report presents a chronological history of the mining activities in the Renton Mine. They are summarized briefly in Table 1. TABLE 1 Year Activity 1874 Opened by the Renton Coal Company 1886 Closed 1895 Reopened by the Renton Cooperative Company i 1901 Bought out by the Seattle Electric Company 1920 Closed 1922 Reopened by the Strain Coal Company 1933 Closed ir.: • - The primary workings of the Renton Mine consisted of the No. 3 seam. The No. 3 seam �i'., is documented to be about 111/2 feet thick, dipping toward the east at about 7 to 10 degrees. A . Map of the mined out area with an overlay of the project site is presented in Figure 2. It should be noted that there are discrepancies in the literature reporting the history of the mine. The mine 8 . records indicate that about 95 percent of the coal was extracted from the No. 3 seam. However, - - • a consultant report(Evans 1920) estimated that about 21 percent of the coal was mined out based 1 . on reported quantities. It should also be noted that our experience on similar projects indicates that survey data of mines prepared prior to 1930 do not have a high degree of accuracy. F, We have presented the,outline of a relatively large "room" that may have been entirely J'`L.. mined out below the site. The historical map indicates the eastern and western extremities of this large room were mined out; however, the reference map fades out in the middle and it is unclear whether the entire area between these extremities actually was mined. We have shown it on the . figure as the entire room having been mined out to be conservative. i i B - 1 File No.0693-044-02-1130/032296 G e o E n g i n e e r s ►: • The mine records indicate approximately 875 feet to 990 feet of overburden rock and soil • above the mined out area. The relative thickness of overburden above the mine workings across • the site is indicated in Figure 2. The geologic map of the site indicates a relatively thin veneer of glacial drift soils overlying the bedrock in this area. We estimate that the depth of glacial till soils is probably less than 100 feet across the site. A surface expression of mine collapse (such as a pit) is unprecedented for a mine with this thickness of overburden in all case histories and technical reference papers that we reviewed. A 1 slight possibility exists that downwarping of the ground surface may occur over a very large area, especially if the large room was mined out, as indicated in Figure 2. The maximum potential 1, .• vertical displacement is estimated to be on the order of 2 feet or less. The surface manifestation of this downwarping would occur over a very large area extending well beyond the boundaries 1..; of the project site. A significant percentage of any resultant downwarping may have already occurred since the mine has not been worked since 1933. Based on the average 930-foot thickness of overburden, case histories, and our analyses, we conclude that there is a very low risk of any hazard from the previous mining activity to reservoirs located on this site. . ` SEISMIC CONSIDERATIONS The seismotectonics of the Puget lowland are very complex and not well understood due to the thick glacial deposits over the bedrock. The primary cause of the seismicity in the Pacific Northwest is believed to be the result of the interaction of the Pacific and North American litho- spheric plates, further interrelated with the smaller Juan de Fuca plate. The larger earthquakes -l - in the region are thought to be subduction-related with tension in the lower plate; however, the evidence is inconsistent. While the Puget Sound region has been subject to many seismic events, _ r-, the two major historical events affecting the local area are the Olympia earthquake of 1949 and the Seattle-Tacoma earthquake of 1965. The 1949 earthquake is the strongest recorded . 'earthquake in the Puget Sound region, with a Richter magnitude of 7.1 and felt over an area of `•' - at least 150,000 square miles. -The 1965 earthquake was a magnitude 6.5 event. Earthquakes - of similar or larger magnitudes are possible in the Puget Sound region in the future. It should . be noted that the larger recorded Puget Sound earthquakes have occurred at relatively great depths without any associated surface faulting. Two faults are mapped in the site area. We performed a literature search to evaluate the geologic conditions and geometry of the faults mapped with respect to potential seismic hazards to the project. A list of selected references is presented in Appendix C. Bedrock in the Puget Sound lowlands is generally covered by a relatively thick layer of J' '' glacial •drift and more recent deposits. This relatively thick mantling of soil generally masks the structural fabric of the bedrock and therefore very little is known about the fabric of the bedrock - in the Puget Sound lowland area. In the Renton and South King County vicinity, the bedrock is generally closer to the ground surface, thus permitting practical and economical mining of coal seams. Faults in the bedrock formations were frequently encountered during the mining. These faults were typically mapped; therefore, much more detailed information with respect to the G e o E n g i n e e r s B - 2 File No.0693-044-02-1130/032296 Ibedrock fabric is }mown in mined areas. The bedrock is of Eocene age which dates back about 60 million years. Soon after deposition of the coal beds and encasing sandstone, the sediments were folded and faulted by tectonic forces, probably in late Miocene time, about 18 million years ago. Two faults, known as Fault No. 3 and Fault No. 4, were mapped in the Renton Mine within the downward projected footprint of the project site. The approximate locations of these faults are shown in Figure 2. These faults are described in some detail in the literature (Evans 1920). The faults are described as being "normal faults," each having 7 feet of offset. The planes of Fault No. 3 and Fault No. 4 dip at 75 degrees and 60 degrees to the south, 1 respectively. Projection of the nearest fault plane to the ground surface would place the fault line ., emergence about 250 feet to the north of the project site. The 7 feet of offset reported along the 1 faults below the site is quite small from a geologic perspective. A larger fault located south of 1 the site is reported to have an offset on the order of 1 mile. L. As mentioned above, an average of about 930 feet of overburden exists over the mined out area at the location of the project site. No lineaments or other surface features indicating surficial faulting were observed at the site during the site reconnaissance performed for that purpose or during the field exploration program for the foundation investigation. In addition to the above mentioned historical earthquake records, recent research has focussed on two source areas for very large earthquakes: (1) subduction zone earthquakes off the Washington coast with magnitudes estimated at 8.0 to 9.5, and (2) Seattle Fault earthquakes with magnitudes estimated at 7.5 or larger. Subduction zone earthquakes are generally located at depths of about 35 kilometers and at a distance of about 150 to 270 kilometers from the site. - The energy and magnitude of ground motion is generally attenuated (reduced) prior to reaching the Puget Sound area. The Seattle Fault which has been the focus of recent study is thought to Iconsist of a series of four or more eat-west trending faults, which extend from the Kitsap Peninsula to the Cascade foothills. One of the results in this zone passes below the south end of Elliott Bay and extends east along the interstate 90 corridor. The fault is located about 10 I. ' kilometers below the ground surface and about 12 kilometers from the site. The potential impacts .of large earthquakes generated in these source areas is discussed in the "Seismic Considerations" . section of this.report. • • G e o E n g i nee r s B - 3 File No.0693-044-02-1130/032296 • . \ 1 .. ! t • Oi :.

City of Renton Rolling Hills Reservoir Drainage Information Stormwater Design Site Design Plans Tank Overflow Pond and Control Structure Geotechnical Report Downstream Information �04 o f wAs�r��, 96' 4‘� 1 i 96 f ?N, °ISTOL G.�ti .,. sONALti ' EXPIRES ©/ LpP��R�`v�.,.� � UG 2 0 1c.,�:,� cteG RH2 Engineering Stormwater Design City of Renton-Rolling Hills Reservoir Stormwater Improvements The stormwater improvements for the Rolling Hills Reservoir conform to the standards and criteria set forth by the King County Storm Water Design Manual. A stormwater analysis was conducted to evaluate the impacts that construction of surfaces would have on the site's natural drainage. These surfaces include: the tank roof,the booster pump station roof,the tank perimeter road, and the pump station access driveway. In addition, the storm water design for this project addresses discharges from the reservoir during emergency overflows and maintenance drainage. The existing site conditions for this project consist of second growth forest, mainly deciduous trees,with dense underbrush. The site is located on top of a small ridge. There is no evidence of channelized flow or streams on this site. The site is approximately 13 acres in size and construction will only impact the northeastern half. A small drainage swale is located along the northeast property line and runs along the Puget Drive S.E.right-of-way. A water impoundment area will be constructed as part of this project to contain 100% of the reservoir volume in the unlikely event of tank rupture. This impoundment area will also be utilized to contain emergency overflows,maintenance drainage,and stormwater runoff. Hydrologic analysis and hydrograph routing using the Waterworks Program by Engenous Systems, was performed for this site to evaluate the impacts of the 2-year and 100-year storm events. The stormwater analysis was conducted to verify that this site qualified for stormwater runoff quality and quantity exemptions. This project is exempt from providing on-site peak rate runoff control due to negligible peak runoff rate increases. The peak runoff increase for this site due to this project for the 24-hour 100-year event is less than 0.5 cfs. Therefore,no detention is required for this project. Stormwater requirements state that water quality facilities must be provided for any new impervious surface greater than 5,000 square feet that is subjected to vehicular traffic. The access driveway and perimeter road will be gravel and not paved. Both the access driveway and perimeter road will be subjected to only two or three vehicular trips a week, when a City vehicle visits the site for tank and pump station maintenance purposes. Access to the driveway and perimeter road will be gated and restricted to vehicles at all other times. Therefore, potential for oil and grease contamination of the driveway will be minimized and no water quality treatment will be necessary. Runoff generated on the tank roof, perimeter road, and pump station roof is be routed to the impoundment area. This impoundment area has a control structure which discharges to the tightlined storm system through an 3.8-inch diameter orifice. This orifice is sized to drain the total tank volume over a 7-day period (3 MG at 0.66 cfs). This flow rate is substantially lower than the pre-developed 100-year storm event peak runoff rate of 1.67 cfs and closely approximates the pre-developed 10-year storm event peak runoff rate of 0.73 cfs. The downstream stormwater system was evaluated in the 1988 Pre-design Report. This report determined that the downstream stormwater system has a maximum capacity of 5.5 cfs. This flow rate assumes that all downstream pipes are clear of sediments and blockages. The control structure for the impoundment area will release flows at 0.66 cfs up to a maximum impoundment elevation of 456.5'. In addition to this outlet the control structure will have an emergency drainage orifice that can be opened to drain the impoundment area at a maximum flow rate of 5.4 cfs. This 7.6-inch diameter orifice can be accessed by opening a shear gate in the control manhole and the total tank volume can be drained in approximately 20 hours. REN/194.062/S torm-sum.doc - . . .

The site is located south and west of the intersection of Puget Drive Southeast and Edmonds Avenue Southeast, as shown on the Site Plan, Figure 1. GeoEngineers presented the results of our Phase I and II portions of the site study in our "Report, Geotechnical Engineering Services,Proposed Rolling Hills Reservoir and Booster Pump Station, Renton, Washington" dated April 13, 1988. Our Phase I study included an evaluation of the historical mining hazard and fault/earthquake hazard and the Phase II study presented the results of specific foundation explorations and design and construction recommendations. We understand that the proposed project will consist of constructing. two water storage • tanks, each with a 4-million-gallon capacity. The tanks are expected to be about 40 feet high with their base at Elevation 453 and overflow at Elevation 490. The tanks will be about 130 feet in diameter and be constructed as at-grade steel structures. We also understand that the south tank shown on our site plan will be constructed at this time and the other tank in the future. A booster pump station will be located adjacent to the new tanks and will pump to the city's existing elevated tank located on the site. SCOPE • .The purpose of our services for this phase of the project is to provide geotechnical design . recommendations based on the subsurface soil and ground water information obtained during our 1988 study. The specific scope of our services consists of the following tasks: 1. Attend one meeting with representatives of RH2 Engineering to discuss the design elements . for the project. 2. Review available soil and ground water information obtained during our previous study and for nearby studies. 3. Review information and describe the risks associated with previously identified potential • geologic hazards at the site. 4. Describe and characterize soil and ground water conditions at the site. J G e o E n g i n c e r s 1 File No.0693-044-02-1130/032296 5. Provide recommendations for site preparation and earthwork including estimated stripping depths, use of on-site soil for structural fill and trench backfill, and requirements for imported fill. This will also include recommendations for placement and compaction of structural fill and a discussion of wet weather construction considerations. 6. Provide recommendations for temporary excavation and trench side slopes, and permanent cut and fill slope inclinations. This will include recommendations for dewatering and temporary excavation shoring, if necessary. 7. Establish design values for foundation support, estimated postconstruction settlement of the proposed facilities, and active and passive lateral earth pressures for design of below grade elements. This will include the coefficient of base friction to resist lateral loads. 8. Provide recommendations for access road construction and design pavement section. 9. Provide seismic design coefficients based on the UBC (Uniform Building Code) seismic criteria. 10. Prepare a written report presenting our findings and recommendations. SITE CONDITIONS GENERAL GeoEngineers completed an assessment of geologic ha7.2rds in the project area as part of our 1988 study. The results of that study and comments regarding studies and information available since then pertaining to potential geologic hazards is provided in Appendix B. The summary in Appendix B pertains to both coal mine and seismic hazards. Based on our review i and recent research, it is our opinion that there is a low risk of hazard from the presence of deep coal mines below the site. The "Conclusions and Recommendations" section of this report provides our recommendations for reducing seismic risks. -SURFACE CONDITIONS - The site is approximately 10 acres in area, with current development limited to the city of Renton's existing elevated water-tank. We noted several minor excavations or areas of ground - modification during our site reconnaissance and field exploration program as part of our previous :study. The site has been logged at least once with only scattered evergreen trees remaining. Most of the site is covered with relatively thick brush and small- to moderate-sized deciduous trees. A topographic ridge trends in a generally north to south direction across the site. The east flank of the ridge is a very gentle slope, dropping about 10 feet of elevation in 300 feet. The i. west flank is a more moderate slope, dropping about 10 feet in 100 feet, and then sloping slightly steeper toward the property boundary. The general site topography is shown in Figure 1. • G e o E n g i n e e r s 2 File No.0693-044-02-1130/032296 r SUBSURFACE CONDITIONS Subsurface conditions at the project site were evaluated as part of our previous study by excavating eight test pits at the locations shown in Figure 1. A detailed discussion of the exploration procedures and logs of the test pits are presented in Appendix A. The subsurface conditions encountered in our test pits were relatively uniform. An exception was Test Pit 5, which encountered about 1 foot of fill soils with considerable organic matter apparently associated with previous grading performed on the site. The explorations - indicate the site is mantled by a layer of forest duff, sod and topsoil up to about 0.5 feet in thickness. Greater depths of organics should be expected in densely vegetated areas. The topsoil generally overlies a variable thickness of loose to medium dense brown silty fine sand with a trace of gravel. Occasional roots were noted in several of the test pits to a depth of about 2 feet. Below a depth which varied from about 3 to 6-1/2 feet of depth, very dense gray silty sand with gravel, occasional cobbles and boulders was encountered in all the test pits. This stratum is referred to geologically as glacial till and has been compressed under the weight of glacial ice. The upper loose to medium dense soils represent the weathered horizon of the glacial till. The subsurface conditions are shown in the Generalized Geologic Cross Sections, Figure 2. The locations of the sections are shown in Figure 1. GROUND WATER CONDITIONS Very slow ground water seepage was observed within a sandy layer of the glacial till in Test Pit 1. Slow ground water seepage was also observed in Test Pit 8 at the bottom of the weathered horizon. No ground water seepage was observed in any of the other test pits. Fluctuations in ground water conditions should be expected as a result of changes in season, precipitation and other factors. A perched ground water condition likely occurs seasonally at the bottom of the weathered till layer which overlies very dense relatively impermeable unweathered till. - • - CONCLUSIONS AND RECOMMENDATIONS GENERAL - • - The two water storage tanks and booster pump station can be constructed on the site as � proposed provided site earthwork and foundation preparation is completed as recommended below. The tanks and building footings should be founded on the medium dense to dense native till or properly placed structural fill. SITE PREPARATION AND EARTHWORK The following recommendations apply to all earthwork and structural fill placement and compaction. . • Portions of the site where structures or access roads will be located should be stripped of vegetation and topsoil: Based on the explorations, we expect that stripping depths will average about 6 inches. G e o E n g i n e e r s 3 File No. 0693-044-02.1130/032296 • Additional stripping depths may be necessary where trees are removed and if the site soils are softened during construction. • Temporary cuts are expected to encounter weathered and unweathered glacial till. • The exposed subgrade must be compacted to a firm, nonyielding condition prior to placing structural fill or formwork. • For planning purposes, we recommend that temporary cuts into the weathered till be sloped at a maximum of 11/2H:1V (horizontal to vertical) and unweathered till 1H:1V for cuts less than about 8 feet in height. • Sloughing or spalling of either of these zones could occur at these slope angles and some .44 modifications for safety purposes may be necessary. Construction grades should prevent surface water from entering the excavation. Erosion protection such as plastic sheeting should be applied during wet weather conditions. • The native weathered and unweathered till will be suitable for structural fill in roadway areas, but only if the moisture content can be controlled. *We recommend using imported - structural fill for support of tank and building foundations, and floor slabs. • Imported structural fill should consist of sand and gravel containing less than 5 percent fines by weight relative to the fraction of the material passing the 3/4-inch sieve. This imported • fill material should be free of rock fragments larger than 6 inches, debris and organic materials. • Structural fill placed in proposed foundation and floor slab areas must be compacted to at least 95 percent of MDD (maximum dry density) (per ASTM D-1557). • Structural fill placed in utility trenches should be compacted to at least 90 percent, except in any areas to be paved. In these areas the upper 2 feet below finished subgrade must be compacted to at least 95 percent of the same standard. • - The site soils possess a high silt cortent. These soils are easily disturbed during wet • • weather conditions. We recommend the earthwork be performed during the drier summer months. Construction traffic should be minimized in the foundation area during wet weather. It may-be necessary to blanket the glacial till soils with pit run or crushed rock in order to - • minimize disturbance during wet weather construction activities. It will be necessary to recompact or remove soils loosened or softened during construction as discussed above. Specific 3 erosion/sediment control facilities must be included in the grading design because of high erosion potential of the on-site soils. 1 FOUNDATION CONSIDERATIONS • • Water Storage Tanks • The tanks should be supported on a ringwall footing or mat foundation with a thickened edge. G e o E n g i n e e r s 4 File No.0693-044-02-1130/032296 : -1 • The foundation should bear on the dense to very dense native till encountered in our test pits. A mud mat should be placed immediately after foundation excavation to protect the subgrade. • Ringwall footings should be at least 18 inches wide and extend at least 18 inches below the lowest adjacent finish grade for frost protection. • Provided the subgrade is prepared as recommended above, an allowable bearing pressure of 5,000 psf(pounds per square foot) may be used for the total of dead and long-term live loads. 1,4 • This allowable bearing pressure may be increased by up to one-third for short duration live loads such as those resulting from wind and seismic loads. • We recommend that the floor slab or tank bottom be supported on at least a 6-inch thickness of crushed rock compacted to at least 95 percent MDD. • All trench bacldill within the tank area should consists of imported structural fill, as described above, compacted to at least 95 percent MDD. •h. We estimate that postconstrtiction settlement of the tank, supported as recommended above, should be less than 1/2 inch under full loading with differential settlem,nt of less than 1/4 inch. This settlement should be largely completed after the initial full height water test is done. Booster Pump Station • The booster pump station building can be supported on conventional spread footings founded either on the native dense till or on a pad of structural fill. • The zone of structural fill supporting foundation elements should extend laterally beyond the foundation edges a horizontal distance at least equal to the thickness of the structural fill placed. • The building footings should be at least 18 inches wide. • For frost protection,the footings should be founded at least 18 inches below lowest adjacent rs: finished grade. • • • Footings supported on native subgrade or a structural fill pad extending to the native dense fill prepared as recommended above can be designed using an allowable bearing pressure • of 3,000 psf for the total of dead and long-term live loads. • This allowable bearing pressure may be increased by up to one-third for short-term live loads such as those resulting from wind or seismic forces. • A base course consisting of at least 4 inches of free-draining gravel containing less than 3 percent fines should be placed beneath the floor slab to provide uniform support and a • capillary break. • • A vapor barrier such as plastic sheeting may be used to provide added protection against the upward migration of moisture into the floor slab, if appropriate. • A 2-inch-thick layer of sand should be placed over the vapor barrier for protection against damage during concrete placement. G e o E n g i n e c r s 5 File No.0693-044-02-1130/032296 We estimate that the postconstruction settlement of both footings and floor slab, supported as recommended above, will be less than 1/2 inch. Most of this settlement is expected to occur as loads are applied. Lateral Resistance • Passive resistance should be evaluated using an equivalent fluid density of 350 pcf(pounds per cubic foot) on the sides of the tank ringwall and the pump house footings. This value includes a factor of safety of about 1.5. • Resistance to passive pressure should be calculated from below a depth of 1 foot measured from the lowest adjacent ground surface unless the adjacent area is paved. In that case, passive resistance can be calculated from the finished pavement surface. • This passive resistance applies where structural fill compacted to at least 95 percent MDD extends outward at least two times the depth of the footing or tank ringwall. • Frictional resistance can be evaluated using 0.4 for the coefficient of base friction against foundation elements. This value includes a factor of safety of about 1.5. We recommend that all footing excavations be evaluated by a representative of our firm immediately before any mud mat structural fill, crushed rock, sand and gravel, steel or concrete is placed, to determine if the work is completed in accordance with our recommendations and that subsurface conditions are as expected. UTILITY TRENCHES We expect that utility trench excavations will be constructed using conventional open-cut techniques. The following recommendations apply to excavation and backfill. • All shoring and temporary slopes should conform to applicable local, state and federal - . safety regulations. - For planning purposes, temporary excavations within the upper layer of weathered till ,which are in excess of 4 feet but less than 8 feet in depth should be sloped at no steeper than 11/H:1V unless lateral support of the trench sides is provided. The portions of : temporary excavations within the underlying unweathered till should be sloped at no steeper than 1H:1V. • . Ground water seepage, if encountered during excavation, may be controlled by ditching and using sump pumps, as necessary. • Trench backfill may consist of the weathered and unweathered till if adequate compaction can be achieved. If construction takes place during periods of wet weather imported structural fill may be required to achieve adequate compaction. • Soil imported for trench backfill should meet the requirements of structural fill presented above. • Backfill placement and compaction should meet the requirements presented above for structural fill. G e o E n g i n e e r s 6 File No.0693-044-02-1130/032296 DRAINAGE CONSIDERATIONS We recommend that a perforated perimeter drain be installed at the footing elevation of the proposed booster pump building and at the bottom of any equipment sumps which extend below footing elevation. A perforated drain should also be placed for the reservoirs if the site grades are such that hydrostatic pressures could develop below the tank bottom. These perforated drains should be collected and routed by a gravity tightline to a suitable discharge point. Provisions should be made for water collected under the bottom of the reservoir to drain into the perimeter drain or other suitable discharge. Surface drainage systems should be installed in conjunction with the proposed booster pump building and water storage tanks. Roof drains should be tightlined to a suitable discharge point well away from the tanks and booster pump building. Roof drains must not be discharged at a location or in a manner that water can back up into the i,. footing or subslab drains. The ground surface adjacent to the tanks and building should be sloped to drain away from the structures. SEISMIC CONSIDERATIONS The project site is located within the Puget Sound region which is a moderately active seismic area. We spoke with Mr. Steve Savage of Coughlin Porter Lundeen (project structural engineers) and understand that water storage tanks are typically designed to resist seismically induced lateral loads by using a pseudo-dynamic design approach in accordance with either the UBC (Uniform Building Code) Section 1632 or AWWA (American Water Works Association) D-100 methodology for steel tank design. Both approaches establish a ground acceleration based • • on zonation maps for the United States. According to the 1994 Edition of the Uniform Building Code, the project site is located within Seismic Risk Zone 3 with a Seismic Zone Factor (Z) of 0.30. This zone generally corresponds to a ground acceleration of about 0.30g, where g is the gravitational constant. As defined in the Uniform Building Code, the site is best classified as a Soil Profile Type Si. This • . profile type consists of "dense or stiff soil conditions where the depth of soil exceeds 200 feet." _ • .We also completed a site specific seismic evaluation to determine the ground response during an earthquake and the maximum likely ground acceleration for two scenarios: (1) a subduction zone.earthquake off the coast of Washington, and (2) an event along the Seattle Fault • which is represented by a series of east-west trending faults which extend through the Seattle area. The site specific evaluation was completed using the SHAKE2 computer program developed by researchers at the University of California, Berkeley. Subduction zone earthquakes located along the coast of Washington are thought to be capable of generating earthquakes of magnitude 8.5 or greater. Earthquakes along the subduction zone are generally located at depths of about 35 kilometers and at a distance of about 150 to 270 kilometers from the site. . The energy and magnitude of ground motion for these earthquakes, particularly the moderate to high frequency motions, are generally attenuated (reduced) prior to reaching the Puget Sound area. Based on our site specific evaluation, it is our opinion that G e o E n g i n e e r s 7 File No.0693-044-02-1130/032296 ground accelerations of 0.14g to 0.20g may be expected at the site. These accelerations are based on peak bedrock accelerations of 0.09g to 0.13g and the soil conditions at the site. These ground accelerations are well within the general range of accelerations applied by the pseudo dynamic approach of the UBC or AWWA. However, the period of the ground motions will be longer which may develop higher dynamic forces within a tank from the sloshing liquid. A site response spectra is included in Figure 3 for a subduction zone event. The UBC response spectra is also shown in Figure 3. A shallow nearby fault such as the Seattle Fault may result in relatively high ground motions resulting from a moderate magnitude earthquake. The Seattle Fault has been studied and evaluated for years. New developments in research indicate that the Seattle Fault is a series of ki four or more east-west trending, south dipping faults which extends from the Kitsap Peninsula �..., to the Cascade foothills. The fault zone passes below the south portion of Elliott Bay and extends east to Issaquah generally along the Interstate 90 corridor. The fault is located about 10 kilometers below the ground surface and about 12 kilometers north of the site. The likely maximum magnitude of earthquakes generated along this fault is about 7 to 7.5. Based on our site specific evaluation, it is our opinion that ground accelerations of 0.60g to 0.80g may occur ' = at the site during a strong earthquake. These accelerations are based on peak bedrock accelerations of 0.40g to 0.57g and the soil conditions at the site. A ground response spectra is presented in Figure 4 for a Seattle Fault event along with the UBC response spectra. Our analysis suggests that relatively high levels of ground shaking will likely occur at the foundation level of the tanks should an earthquake occur along the Seattle Fault or along the subduction zone off the coast of Washington. These two events represent maximum credible earthquakes which implies that the level of ground shaking is never the maximum that can be expected. They are not included in the standard design values contained in the UBC, Zone III areas. In addition, the UBC standard for zone III areas is for a period of ground shaking on the -order of 30 seconds or less. The subduction zone event.could cause ground shaking which might last two minutes or more. The number of cycles and duration of shaking should be considered in the tank design. • We recommend that the structural engineer evaluate the effect that the ground motions : presented herein may have on the structural design of the tank. This can then be compared with :the structural requirements for a standard UBC design. This comparison would allow a cost evaluation of upgrading the tank design to withstand a larger earthquake than the standard UBC design earthquake. The city of Renton could then use this information to decide whether they 1 =' are willing to pay an additional cost to reduce potential risks during a maximum credible earthquake: • ROADWAY PAVEMENT DESIGN The following pavement recommendations are based on typical traffic conditions for this type of facility. We expect that much of the traffic will consist of light trucks and that occasional heavy trucks will access the area for maintenance. Very slow vehicle speeds are also assumed. G e o E n g i n e e r s 8 File No.0693-044-02-1130/032296 .• The exposed subgrade in roadway and pavement areas should be prepared as recommended above under "Site Preparation." The subgrade should be proofrolled immediately prior to placing the subbase material. Soft or disturbed areas which develop in the subgrade should be removed and replaced with granular fill compacted as recommended to provide adequate pavement support. We recommend that the pavement section for the access road consist of 2 inches of Class B • asphalt concrete over 4 inches of crushed rock, provided the subgrade is prepared as recommended and that pavement construction is done during a period of extended dry weather. • The pavement section presented above is based on having a relatively dry and properly compacted subgrade as defined above on which to place the subbase, base course and paving. All new Class B asphalt concrete pavement materials and placement should generally conform to Section 5-04, WSDOT (Washington State Department of Transportation) 1991 Standard • Specifications for Road, Bridge and Municipal Construction. Asphalt concrete should be • compacted to at least 92 percent of Rice density. All crushed rock should conform to Section 9- 03.9(3) of the Standard Specifications. The crushed rock and subbase where recommended should each be compacted to at least 95 percent of the maximum dry density determined in accordance with ASTM D-1557. It is important to pavement performance that baclf-ill in utility trenches located in areas to be paved also be compacted as specified for structural fill.

The explorations locations 1 were determined in the field by measuring from survey stakes provided by others indicating the 1 proposed reservoir locations. The elevations were determined based on their location with respect to topographic information presented on a preliminary plan by RH2 Engineering dated 2/4/88. The test pits were excavated to approximately 10 feet of depth using a rubber-tired backhoe L. under subcontract to our firm. The test pit explorations were continuously monitored by a geotechnical engineer from our firm who maintained a detailed log of the soils encountered, 1` obtained representative soil samples, and observed ground water conditions. Soils encountered were classified in general accordance with the soil classification system shown in Figure A-1. The test pit logs are presented in Figures A-2 through A-4. All soils samples were brought to our laboratory for further examination. Al samples were tested to determine their moisture content which is presented on the logs. I, 1 - r - I ! . I I T .

I Similar to many areas in the Renton and South King County vicinity, underground mining activity occurred below the site in the early 1900s. We performed a literature search to determine the extent of the coal mining activity that was undertaken below the site. Based on this I information, we evaluated the potential hazard this historic mining might pose to the proposed project. A list of selected references is presented in Appendix B. liqa i . _ The referenced Morrison/Knudsen report presents a chronological history of the mining activities in the Renton Mine. They are summarized briefly in Table 1. • TABLE 1 -17 Year Activity 1874 Opened by the Renton Coal Company 1886 Closed ] .. 1895 Reopened by the Renton Cooperative Company 1901 Bought out by the Seattle Electric Company i - 1920 Closed 1922 Reopened by the Strain Coal Company 1933 Closed • The primary workings of the Renton Mine consisted of the No. 3 seam. The No. 3 seam . is documented to be about 11'/ feet thick, dipping toward the east at about 7 to 10 degrees. A .1. , map of the mined out area with an overlay of the project site is presented in Figure 2. It should be noted that there are discrepancies in the literature reporting the history of the mine. The mine i'r4 . records indicate that about 95 percent of the coal was extracted from the No. 3 seam. However, . • a consultant report(Evans 1920) estimated that about 21 percent of the coal was mined out based 1 , on reported quantities. It should also be noted that our experience on similar projects indicates that survey data of mines prepared prior to 1930 do not have a high degree of accuracy. 1 • We have presented the.outline of a relatively large "room" that may have been entirely ,... mined out below the site. The historical map indicates the eastern and western extremities of this large room were mined out; however, the reference map fades out in the middle and it is unclear jwhether the entire area between these extremities actually was mined. We have shown it on the . figure as the entire room having been mined out to be conservative. • G e o E n g i n e e r s B - 1 File No.0693-044-02-1130/032296 i 1 The mine records indicate approximately 875 feet to 990 feet of overburden rock and soil above the mined out area. The relative thickness of overburden above the mine workings across . , the site is indicated in Figure 2. The geologic map of the site indicates a relatively thin veneer of glacial drift soils overlying the bedrock in this area. We estimate that the depth of glacial till soils is probably less than 100 feet across the site.1 .A surface expression of mine collapse (such as a pit) is unprecedented for a mine with this thickness of overburden in all case histories and technical reference papers that we reviewed. A slight possibility exists that downwarping of the ground surface may occur over a very large area, I especially if the large room was mined out, as indicated in Figure 2. The maximum potential 7;‘., vertical displacement is estimated to be on the order of 2 feet or less. The surface manifestation II , - of this downwarping would occur over a very large area extending well beyond the boundaries in of the project site. A significant percentage of any resultant downwarping may have already j occurred since the mine has not been worked since 1933. Based on the average 930-foot thickness of overburden, case histories, and our analyses, we conclude that there is a very low risk of any hazard from the previous mining activity to reservoirs located on this site. t ' SEISMIC CONSIDERATIONS 3 . The seismotectonics of the Puget lowland are very complex and not well understood due to the thick glacial deposits over the bedrock. The primary cause of the seismicity in the Pacific f_:• Northwest is believed to be the result of the interaction of the Pacific and North American litho- spheric plates, further interrelated with the smaller Juan de Fuca plate. The larger earthquakes ti' . in the region are thought to be subduction-related with tension in the lower plate; however, the - evidence is inconsistent. While the Puget Sound region has been subject to many seismic events, - - the two major historical events affecting the local area are the Olympia earthquake of 1949 and the Seattle-Tacoma earthquake of 1965. The 1949 earthquake is the strongest recorded . "earthquake in the Puget Sound region, with a Richter magnitude of 7.1 and felt over an area of ] , - . - at least 150,000 square miles. .The 1965 earthquake was a magnitude 6.5 event. Earthquakes of similar or larger magnitudes are possible in the Puget Sound region in the future. It should jm . be noted that the larger recorded Puget Sound earthquakes have occurred at relatively great - depths without any associated surface faulting. • Two faults are mapped in the site area. We performed a literature search to evaluate the 1 . geologic conditions and geometry of the faults mapped with respect to potential seismic hazards to the project. A list of selected references is presented in Appendix C. 1 Bedrock in the Puget Sound lowlands is generally covered by a relatively thick layer of glacial drift and more recent deposits. This relatively thick mantling of soil generally masks the structural fabric of the bedrock and therefore very little is known about the fabric of the bedrock i . _ . . in'the Puget Sound lowland area. In the Renton and South King County vicinity, the bedrock - is generally closer to the ground surface, thus permitting practical and economical mining of coal seams. Faults in the bedrock formations were frequently encountered during the mining. These faults were typically mapped; therefore, much more detailed information with respect to the G e o E n g i n e e r s B - 2 File No.0693-044-02-1130/032296 bedrock fabric is known in mined areas. The bedrock is of Eocene age which dates back about 60 million years. Soon after deposition of the coal beds and encasing sandstone, the sediments 1 were folded and faulted by tectonic forces, probably in late Miocene time, about.18 million years : ago. Two faults, known as Fault No. 3 and Fault No. 4, were mapped in the Renton Mine a within the downward projected footprint of the project site. The approximate locations of these faults are shown in Figure 2. These faults are described in some detail in the literature (Evans 1 1920). The faults are described as being "normal faults," each having 7 feet of offset. The planes of Fault No. 3 and Fault No. 4 dip at 75 degrees and 60 degrees to the south, I • respectively. Projection of the nearest fault plane to the ground surface would place the fault line emergence about 250 feet to the north of the project site. The 7 feet of offset reported along the faults below the site is quite small from a geologic perspective. A larger fault located south of the site is reported to have an offset on the order of 1 mile. 19 - As mentioned above, an average of about 930 feet of overburden exists over the mined out 1 . area at the location of the project site. No lineaments or other surface features indicating surficial faulting were observed at the site during the site reconnaissance performed for that purpose or 1 ^ during the field exploration program for the foundation investigation. In addition to the above mentioned historical earthquake records, recent research has focussed on two source areas for very large earthquakes: (1) subduction zone earthquakes off the Washington coast with magnitudes estimated at 8.0 to 9.5, and (2) Seattle Fault earthquakes with magnitudes estimated at 7.5 or larger. Subduction zone earthquakes are generally located at depths of about 35 kilometers and at a distance of about 150 to 270 kilometers from the site. i _ The energy and magnitude of ground motion is generally attenuated (reduced) prior to reaching the Puget Sound area. The Seattle Fault which has been the focus of recent study is thought to consist of a series of four or more eat-west trending faults, which extend from the Kitsap Peninsula to the Cascade foothills. One of the results in this zone passes below the south end of 1 • . . - .Elliott Bay and extends east along the interstate 90 corridor. The fault is located about 10 A. ' kilometers below the ground surface and about 12 kilometers from the site. The potential impacts . .j .of large earthquakes generated in these source areas is discussed in the "Seismic Considerations" - section of this report. . - kti • I .

DOWNSTREAM ANALYSIS The Rolling Hills site is located at the crest of two drainage basins, the Talbot Hill Drainage Basin to the southwest of flipsite, and the Tiffany Park Cascade Drainage Basin to the northeast. Because the site is located on the divide, water can be potentially routed into either basin. The Talbot Hill basin is designated as a critical basin due to drainage problems, therefore, drainage from the site should be directed to the northeast into the Tiffany Park Cascade Basin. This flow path consists of a series of ditches and culverts which ultimately discharge into the Cedar River, and is shown in Figure 7. The first 2500 feet of the drainage path away from the site has been divided into 15 separate sections, each section being defined as a change in maximum capacity of the flow system (such as a change in culvert size, grade or open ditch). Each section has been evaluated to determine the maximum capacity of the section without overtopping the ditches or surcharging manholes. The velocities in each section are also evaluated during the maximum flow rate of the limiting section. Figure 7 depicts the drainage system and Tables 7-1 and 7-2 present the flow rates and velocity evaluations. The evaluation is based on "as-built" records from the City, field, ground and invert elevation measurements, and applying the Manning equation to each of the 15 sections using the Manning "N" constant shown. Note that while performing the field investigation, the following concerns were identified: 1) A property owner adjacent to the catch basin upstream of Section 7 complained that it typically flooded after heavy rains, 2) Section 7 ties in directly to Section 8 without a manhole or catch basin. 3) The 60-inch culvert identified by Section 12 through 15 is up to one-half full of debris, as shown on Figure 7. 4) A manhole may exist and be paved over between Section 11 and 12 according to the "As-Built" records of this storm drain. This evaluation is based on all sections being clean, and also that the first through third sections be re-graded to a uniform slope as indicated on Figure 7, by the dashed line upstream of Section 4. 7-1 • fvug cG ?-'2E D S\ 4,0 R.EPori.7 1 TABLE 7-1 MAXIMUM CAPACITY OF EACH SECTION PERCENT SECTION CHANNEL MATERIAL MANNINGS DITCH SIZE DEPTH LENGTH I.E.Sn I.E.out SLOPE CAPACITY VELOCITY CAPACITY type type _----n SIDE inches inches feet ---feet feet ft/ft ---cfs fps REQUIRED 1,2,6 3 DITCH GRASS 0.050 1.2 30 20.0 393 445.9 443.0 0.74% 15.2 2.0 100► 4 PIPE CONC 0.013 - 12 12.0 107 443.0 441.3 1.55% 4.5 5.7 100% 5 PIPE CONC 0.013 - 16 16.0 97 440.6 439.0 1.65% 9.9 7.1 100% 6 PIPE CONC 0.013 - 12 12.0 133 439.0 436.9 1.59% 4.5 5.7 100% I 7 PIPE CONC 0.013 - 12 12.0 12 12.0 75 435.6 432.3 4.40% 7.5 9.6 100% 8 PIPE CONC 0.013 100 432.3 429.9 2.40% 5.5 7.1 100% 9 PIPE CONC 0.013 - 12 12.0 313 429.9 401.5 9.07% 10.8 13.7 100% 10 PIPE CONC 0.013 - 12 12.0 345 401.5 365.9 10.32% 11.5 14.6 100% 11 PIPE CONC 0.013 - 12 12.0 235 365.9 352.E 5.66% 8.5 10.8 100i 12 PIPE CONC 0.013 60 60.0 253 350.E 349.8 0.32% 147.0 7.5 100% 13 PIPE CONC 0.013 - 60 60.0 75 349.8 349.6 0.27% 135.0 6.9 100% I 14 PIPE CONC 0.013 - 60 60.0 60 60.0 322 349.6 348.6 0.31% 145.7 7.4 100t 15 PIPE CONC 0.013 48 348.6 348.5 0.21% 119.4 6.1 100% I 1 , TABLE 7-2 I FLOW CHARACTERISTICS AT MAXIMUM CAPACITY OF LIMITING SECTION (4.5 CFS) PERCENT SECTION CHANNEL MATERIAL MANNINGS DITCH SIZE DEPTH LENGTH I.E.in I.E.out SLOPE CAPACITY VELOCITY CAPACITY type type n SIDE inches inches feet feet feet ft/ft cfs fps REQUIRED 1,2,6 3 DITCH GRASS 0.050 1.2 30 10.2 393 445.9 443.0 0.74% 4.5 1.5 30% 4 PIPE CONC 0.013 - 12 12.0 107 443.0 441.3 1.554 4.5 5.7 100% I 5 PIPE CONC 0.013 - 16 8.6 97 440.6 439.0 1.65% 4.5 5.9 46% 6 PIPE CONC 0.013 - 12 12.0 133 439.0 436.9 1.59% 4.5 5.7 100% 7 PIPE CONC 0.013 - 12 7.6 75 435.6 432.3 4.40% 4.5 8.7 61% I 8 PIPE CONC 0.013 - 12 12 9.2 100 432.3 429.9 2.40% 4.5 7.0 81% 9 PIPE CONC 0.013 6.1 313 429.9 401.5 9.07% 4.5 11.1 41% 10 PIPE CONC 0.013 - 12 5.9 345 401.5 365.9 10.32% 4.5 11.7 39% 11 PIPE CONC 0.013 - 12 7.0 235 365.9 352.6 5.66% 4.5 9.4 53% I 12 PIPE CONC 0.013 - 60 8.0 253 350.6 349.8 0.32% 4.5 2.9 3% 13 PIPE CONC 0.013 - 60 8.4 75 349.8 349.6 0.27% 4.5 2.7 3% 14 PIPE CONC 0.013 - 60 8.1 322 349.6 348.6 0.31% 4.5 2.9 3% I15 PIPE CONC 0.013 - 60 8.9 48 348.6 348.5 0.21% 4.5 2.5 4% I i I Based on this evaluation the sections which limit the capacity between the proposed facilities and the outfall to a large ditch along Royal Hills Drive SE are sections 4 and 6 with a capacity of 4.5 cfs. Note that the velocities in all sections are not excessive. Potential Impacts from the Site The future facilities could impact the stormwater system as a result of three types of events occurring: 1) increased runoff from increased impervious area, 2) overflow events resulting from a failure in the water system, and 3) draining the reservoirs. Increased runoff resulting from the development will be determined and detention facilities designed in the design phase. The "rational method" will be used for estimating peak runoff rates for a 10 year design storm and the cities stormwater criteria used for designing the detention facility. Overflow events could occur as a result of a control system failure that does not stop a booster pump when the reservoir is full. There are three booster pump stations which could cause this to happen: the North Talbot Hill Booster Pump Station, the Fred Nelsen Booster Pump Station, and the Tiffany Park Booster Pump Station. If such an event occurred the maintenance crew would be notified and the longest response time which would likely occur would be 4 hours. The maximum planned capacities of these pump stations are: Max Capacity North Talbot Hill 5700 gpm 12.7 cfs Tiffany Park 1050 Rpm 2.3 cfs Fred Nelsen 925 gpm 2.1 cfs Assuming that a five year storm event may occur simultaneously with the overflow event, an additional 1.7 cfs (conservatively estimated) would be required. Since the limiting capacity of the storm system is 4.5 cfs, overflow events resulting from Tiffany Park or Fred Nelsen would not cause flooding. A maximum overflow event from the North Talbot Hill Booster Pump Station could cause flooding down Royal Hill Drive SE. To prevent this from occurring, a redundant telemetry link between a float switch in the Rolling Hills reservoir and North Talbot Booster Pump Station is recommended. This control would independently shut down the North Talbot Booster Pump Station or activate a transfer valve that would eliminate the pump station discharge. This alternative is less expensive then modifying the downstream stormwater system to accommodate a 15 cfs flowrate. Further, the 12.7 cfs contribution from the pump station would only exist until the second reservoir is constructed on the site. The last event which could impact the stormwater system would result from draining the reservoir. Normally, the reservoirs would not be drained to the stormwater system. For routine maintenance, the reservoir would be drained into the Talbot Hill reservoir. However, if the water in the reservoir was found to be contaminated and required to be drained to the stormwater system then the reservoir would be drained through an orifice control at a maximum rate equal to the maximum allowed release rate. This rate would 7-3 equal the rate calculated for sizing the detention system. For emergency purposes the reservoir could be drained as rapidly as possible through a 16" drain which would discharge into the ditch at a maximum rate of 27 cfs. This rate would result in minor flooding along the southeast lane of Puget Drive SE and at the intersection of Puget Drive SE and Royal Hills Drive SE and cause a maximum flowrate down Royal Hills Drive SE of 22.5 cfs. The possibility of this event occurring is extremely low, however, and if it did occur it is unlikely to cause major damage. 7-4 DRII•C SC--- ---1- -`�•• `\ -.... - )ti1GCT .._•- `� �\ i, } CITY Of RENTON _'_ - -\� ROLLING HILLS 490 ZONE RESERVOIR ' -YI pIYrw a n,w PRE-DESIGN REPORT xCTal � . _xpww] STORMWATER ANALYSIS \� / FIGURE NO. 7 / / // / 0 , ".�],rG 0l.w lW Ial III r•,(D[. 0110/00•031.0 ^[MOlw[lME lunr lrol Inn) SonWVninl 'nIIt.l .D WC •W 7a1 at Yqn YCna• /i•• YqM MIS I.I 373 „ I]i I St 0 YlplCM 0/01 0033 vin lb 44, nn�.(pDyr r�W(xcna f unPK17 ,.( cocn /la rCO[ vl •}( snore r fn 44 i,exCnw,l1( 7.
