Exhibit No. 5: Drawing No.A-2, Facility Elevations(Received Jan. 29, 1997) C. Project Description/Background: The purpose of the proposed project is to comply with the Lead and Copper Rule of the Safe DrinkingWater Act. PP Currently,the City's drinking water is corrosive, leading to the leaching of copper from customer's plumbing. The measured levels of dissolved copper at customer taps exceed the level which requires the City to take action to H lower the levels. The proposed project will reduce the levels of dissolved copper at customer taps. This will be Iaccomplished by raising the pH level by adding sodium hydroxide and by adding ortho polyphosphate as a ;corrosion inhibitor. A report describing the project and the method for treating the water has been submitted to and approved by the State of Washington Department of Health. The proposed project includes the construction of a 37' wide by 51' long by 16' high building to house storage tanks and dosing equipment. The project will also include the following: • Approximately 1,620 square yards of asphalt paving, • Approximately 350 linear feet of curbing, • Approximately 1,370 linear feet of containment casing with chemical solution lines, • Approximately 720 feet of storm water lines, • 5 manholes plus 3 wet vaults for solids and floatables removal, • Approximately 240 linear feet of sanitary sewer, • Approximately 250 linear feet of buried electrical service line, • Installation of approximately 650 square yards of sod, and • Approximately 1,150 square yards of pavement restoration. ,No trees will be cut down as part of this project. Landscaping will consist of the installation of the sod, noted above, and the installation of a sprinkler system. Currently 38.0 percent of the site is covered by impervious materials. After completion of the project, 39.9 percent of the site will be covered by impervious materials. ADMINCU.DOC/ . Administrative Conditional Use Repot.._. LUA-97-013 Drinking Water Corrosion Control Treatment Facility-Cedar River Site Page 3 The proposed construction will be located along the western edge of the Cedar River Park. The twenty acres of park land is currently used for indoor and outdoor recreation, parks maintenance, and drinking water production. Existing improvements include the Renton Community Recreation Center, the Carco Theater, Wellhouse 8 Wellhouse 9, a fluoridation building, three parks maintenance buildings, a softball field, two picnic shelters, I roadways, and parking areas. The actual site of the proposed building is vacant except for some landscaping. FINDINGS, CONCLUSIONS & DECISION Having reviewed the written record in the matter, the City now makes and enters the following: • G. Findings 1) CONSISTENCY WITH CONDITIONAL USE CRITERIA Section 4-31-36 lists 11 criteria that the Hearing Examiner is asked to consider, along with all other relevant information, in making a decision on a Conditional Use application. These include the following: A. CONSISTENCY WITH THE COMPREHENSIVE PLAN,ZONING CODE&OTHER ORDINANCES: The proposed use shall be compatible with the general purpose, goals, objectives and standard of the Comprehensive Plan, the Zoning Ordinance and any other plan,program, map or ordinance of the City of Renton. (1) COMPREHENSIVE PLAN, ITS ELEMENTS AND POLICIES The proposed project is consistent with the Elements and Policies contained within the Comprehensive Plan. The Land Use Element designates this area as Center Office/Residential. Although the Center Office/Residential designation does not directly address the establishment of City wells and accessory structures several of the are addressed by the design of this facility. The project is accessed from a major street and the site plan has been designed to integrate the surrounding landscaping and architecture of the City park. Policy U-19 calls for the implementation and coordination for the phasing of utility improvements. The proposed project will improve the water supplied by the City to the level now being required by federal standards. (2) ZONING CODE The project site is zoned Center Office/Residential - Public (COR-P). The proposed facility is considered to be a Medium Utility in that is serves a large sub-area of the City. Medium Utilities are allowed in this zone provided that an Administrative Conditional Use Permit is approved. B. COMMUNITY NEED: There shall be a community need for the proposed use at the proposed location. In the determination of community need, the Hearing Examiner shall consider the following factors, among all other relevant information: (1) The proposed location shall not result in either the detrimental over concentration of a particular use within the City or within the immediate area of the proposed use. The project site is located in the Cedar River park adjacent to an existing well. Construction of the corrosion control building will not cause an over concentration of this use in the general area. ADMINCU.DOC/ Administrative Conditional Use Repo'.. LUA-97-013 Drinking Water Corrosion Control Treatment Facility-Cedar River Site Page 4 , (2) That the proposed location is suited for the proposed use. The proposed location is suited for the proposed use. The new building will treat the water that is withdrawn from the aquifer at the adjacent well and one other well in Liberty Park. This location will allow the water from these wells to be treated prior to entering into the main water lines. C. EFFECT ON ADJACENT PROPERTIES: The proposed use at the proposed location shall not result in substantial or undue adverse effects on adjacent property. The following site requirements shall be required: (1) LOT COVERAGE Lot coverage shall conform to the requirements of zone in which the proposed use is to be located. Lot coverage in this zone is limited to 65% of the lot area. The proposed 1,887 square foot building will only cover a small portion of the 20+ acre site. (2) Yards: Yards shall conform to the requirements of the zone in which the proposed use is to be located. Additions to the structure shall not be allowed in any required yard. N/A (3) Height: Building and structure heights shall conform to the requirements of the zone in which the proposed use is to be located. Spires, bel/towers, public utility antennas or similar structure may exceed the height requirement upon approval of a variance. Building heights should be related to surrounding used in order to allow optimal sunlight and ventilation, and minimal obstruction of views from adjacent structures. Building height is limited in this area to 125 feet or as limited by the airport restrictions. Neither of these limits is applicable to the proposed single-story building. D. COMPATIBILITY: The proposed use shall be compatible with the residential scale and character of the neighborhood. (Ord 3599, 1-11-82) The proposed building is being designed to match the existing buildings located on the park. E. PARKING: Parking under the building structure should be encouraged. Lot coverage may be increased to as much as seventy-five percent (75%) of the lot coverage requirement of the zone, in which the proposed use is located, if all parking is provided underground or within the structure. (Ord.3903, 4-22-85) Parking at this building is limited to the area being designed for the truck that will occasionally off-load chemicals at this building. Additional parking, should it ever be required by additional maintenance vehicles, is already provided in the parking areas for the park within which the building is located. F. TRAFFIC: Traffic and circulation patterns of vehicles and pedestrians relating to the proposed use and surrounding area shall be reviewed for potential effects on, and to ensure safe movement in the surrounding area.

Ij MATTHEWS Land Company CONDITIONAL USE PERMIT APPLICATION NEXTEL COMMUNICATIONS, INC. Highlands/Hazen Site(WA0111-2) Spokane,WA APN: 102305-9081-09 March 10, 1997 PROJECT DESCRIPTION I. STATEMENT OF REQUEST Nextel Communications, Inc. (Nextel) requests consideration of a Conditional Use Permit for the construction of an Enhanced Specialized Mobile Radio (EMSR) facility on a hilltop located south of NE 12th Street and east of Duvall Avenue NE in the city of Renton. The proposed facility will consist of a single 120-foot self-supporting lattice tower with multiple antennas and a 220-square-foot prefabricated building for associated electronic equipment. II. SITE SIZE AND LOCATION The proposed communications site will occupy a 1,651-square-foot lease area located within an existing 79,048-square-foot parcel of land presently owned by Robert E. Fricks. The project site would thus encompass approximately 2 percent of the subject property. The site is located.at 1160 Duvall Avenue NE, directly south of NE 12th Street. • III. CURRENT LAND USES AND IMPROVEMENTS The subject property contains one single family residence, located approximately 60 feet southwest of the project site. Another existing telecommunications facility with a lattice tower 'and equipment building is located approximately 16 feet north of the proposed project site. An ,improvement road has been constructed off of NE 12th Street to serve this existing telecommunications facility. The proposed project site will be served by an extension of this access road. Nextel Communications,Inc.-Highlands/Hazen Site Project Description March 10, 1997 Page 2 The site is zoned RM-N (Multi-Family - Neighborhood) and has a Comprehensive Plan , designation of CN(Center Neighborhood). IV. SPECIAL SITE FEATURES No special features (e.g. wetlands, water bodies, steep slopes, etc.) are present at or near the subject site. V. OBSTRUCTION OF VIEWS I Construction of the proposed project will take place on a wooded site currently occupied by a telecommunications tower. The proposed monopole will be slightly above the height of trees in proximity to the site. As a result, no views will be obstructed by construction of the proposed project. VI. DESCRIPTION OF PROPOSED USE AND IMPROVEMENTS Nextel seeks to expand its Pacific Northwest Enhanced Specialized Mobile Radio (ESMR) I network in the Renton area, which will include the proposed site. The project site will occupy a small portion of a large parcel of land. The project consists of an unmanned communication facility with a self-supporting lattice tower and several pieces of electronic equipment as described below. Tower and Antennas The project proposes to construct a 120-foot self-supporting lattice tower to serve as support for ! several antennas. The antennas on the proposed tower will consist of three (3) omni-directional antennas mounted near the top of the tower structure. In addition, two (2) GPS antennas and one (1) test mobile antenna will be mounted on the equipment building. Future plans call for the 1 possible addition of nine (9)panel antennas and(2)two omni antennas to be located on the tower as future demand warrants. • Equipment The equipment shelter will consist of a 10-foot-high prefabricated, state certified, concrete I building. The outside dimensions of this building will be 11' x 20'. This shelter would be used to house associated electronic equipment and other essential equipment for the operation of the facility such as a distribution panel, surge suppressers, battery rack and control cabinet racks. l . Nextel Communications,Inc.-Highlands/Hazen Site Project Description March 10, 1997 Page 3 Site Access and Facility Maintenance Access to the proposed site will be via a gravel road extending north from the project site and will be an extension of an access road currently serving the cellular site to the north. This access road is served by NE 12th Street. The proposed facility will be unmanned, and will not require staffing by personnel. As such, the proposed facility will not generate any employees, and will generate approximately one maintenance visit per month conducted during normal weekday business hours (7:00 a.m. to 5 p.m.). Emergency service would be provided on a 24-hour a day basis as necessary. Public Benefit Nextel's facility will provide significant benefits to the public at large. The public has come to expect and depend upon effective, advanced wireless services to meet its communications needs. This site will greatly improve Nextel's ability to provide the highest quality of uninterrupted service to its users, and comply with network build-out requirements as specified by the Federal Communications Commission. Compliance with State and Local Plans and Policies The project is consistent with the current zoning of RM-N, which allows construction of communications towers and transmission facilities with approval of an administrative conditional use permit. The project also satisfies the requirements of the Federal Communications Commission and the Federal Aviation Administration. f VII. OFF-SITE IMPROVEMENTS No off-site improvements will be required for the proposed project. The proposed project will be an unmanned facility and will not require water or sewer service, and will no result in any impact to local police or fire services. Existing electrical power and telephone service is available to the site and will be upgraded, as needed,to serve the proposed facility.

BACKGROUND ERC MEETING DATE February 25, 1997 Project Name Corrosion Control Treatment Facilities -Cedar River Park Site Applicant City of Renton Water Utility File Number LUA-097-013,ECF Project Manager J.D.Wilson Project Description The proposed project includes the construction of a 37' wide by 51' long by 16'6"high building to house storage tanks and dosing equipment, approximately 1,620 square yards of asphalt paving, approximately 350 linear feet of curbing, approximately 1,370 linear feet of containment casing with chemical solution lines, approximately 720 linear feet of storm water lines with 5 manholes plus 3 wet vaults for solids and floatables removal, approximately 240 linear feet of sanitary sewer lines, approximately 250 linear feet of buried electrical service line, approximately 650 square yards of sod, and approximately 1,150 square yards of pavement restoration. The purpose of the proposed project is to comply with the Lead and Copper Rule of the Safe Drinking Water Act. Currently, the City's drinking water is corrosive. The measured levels of dissolved copper at customer taps exceed the level which requires action by the City to lower the levels. The proposed project will reduce the levels of dissolved copper at customer taps. This will be accomplished by raising the pH of the treated water by adding sodium hydroxide and by adding ortho polyphosphate as a corrosion inhibitor. The proposed treatment must begin by January 1998. Project Location The proposed treatment building will be located at the western edge of the Cedar River Park immediately east of the right-of-way line for I-405 and between the existing fluoridation treatment building and the well house for well PW-9 (SE quarter of the SE quarter of the NW quarter of Section 17, Township 23 North, Range 5 East). The proposed chemical solution lines go from the proposed building to existing wells RW- 1, RW-2, RW-3, PW-8 and PW-9. Wells PW-8 and PW-9 are located along the western edge of Cedar River Park (SE quarter of the SE quarter of the NW quarter of Section 17, Township 23 North, Range 5 East). Wells RW-1, RW-2, and RW-3 are located at the southeast corner of Liberty Park (SW quarter of the SE quarter of the NW quarter of Section 17, Township 23 North,Range 5 East). Exist. Bldg. Area gsf N/A Proposed New Bldg.Area gsf 1,887 Sq. Ft. Site Area 20.6 Acres Total Building Area gsf 1,887 Sq. Ft.

ENVIRONMENTAL IMPACTS Whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development? 1. Earth Impacts: Approximately 270 cubic yards of pavement base,course, 35 cubic yards of structural fill, and 100 cubic yards of pipe bedding material will be hauled in to the work area. The source of these materials will be local aggregate suppliers. Approximately 270 cubic yards of existing soil will be removed to make room for pavement base course material. Approximately 150 cubic yards of material will be removed as part of constructing the foundation for the building. Approximately 120 cubic yards of excess material excavated for trenches will be transported from the work site. Mitigation Measures: Temporary erosion and silt control requirements are included in the project contract specifications. 2. Air Impacts: Diesel and gasoline engine exhaust during construction. Mitigation Measures: None. 3. Water Impacts: The proposed building site is approximately 680 feet from the Cedar River. A portion of the proposed chemical solution feed lines will be approximately 90 feet from the Cedar River. Approximately 360 linear feet of the proposed chemical solution feed line between the proposed treatment building and existing well house for wells RW-1, RW-2 and RW-3 will run approximately parallel to the Cedar River and be within 200 feet of the river. Stormwater will run off from the proposed building roof and the proposed asphalt paving. The stormwater runoff will be collected in stormwater drain pipes, flow through wet vaults to separate floatable and settleable solids, flow through a stormwater pipe sized for detaining the water then connect to an existing 12 inch diameter stormwater pipe which discharges into the Cedar River. The treatment chemicals (25% sodium hydroxide solution and ortho polyphosphate concentrate (AquaMag)) will be delivered to the facility via tanker trucks. The delivery area of the proposed facility will be equipped with a catchment. In the unlikely event of a leak from the delivery truck the leaked chemical would fall into the catchment. During deliveries flow from the catchment is into a containment basin inside the treatment building. Prior to being pumped to wells RW-1, RW-2, RW-3, PW-8 and PW-9 the sodium hydroxide and ortho polyphosphate will be diluted to approximately 3% solution. The pipes used to transfer the chemical solutions to the wells will be located within containment casings. Access vaults along the casing routes will be water tight. The containment casings will be sloped and will drain either to a well house,the treatment building, or a vault. In those cases where the casings drain to a vault the vault will be equipped with a with liquid level sensors which alarm at the water maintenance control room prior to the vault become full. Mitigation Measures: The mitigation measures, described above,are part of the design plans and specifications. 4. Energy Impacts: Electrical energy will be used to power chemical transfer pumps,building lighting and heating. Mitigation: State of Washington Energy Code compliance is provided for in the project design,plans and specifications. City of Renton�PB/PW o Department E, mental Review Committee Staff Report De P CORROSION CONTROL TREATMENT r"HCILITIES-CEDAR RIVER PARK LUA-97-013,ECF REPORT AND DECISION OF(INSERT DECISION DATE) Page5 of 6 5. Environmental Health Impacts: Groundwater will be treated with sodium hydroxide. The sodium hydroxide will be delivered and stored as 25% aqueous solution. The sodium hydroxide will be stored in two 6,500 gallon cross-linked polyethylene tanks. . Sodium hydroxide in aqueous solution can react with ampoteric metals (such as aluminum) generating hydrogen which is flammable and/or explosive when ignited. Sodium hydroxide (25% solution) is a strong caustic alkali. It may react violently with water, acid, and a number of organic compounds. Caustic reacts rapidly with aluminum,tin, and zinc. It will also react with bronze and brass. Twenty-five percent sodium hydroxide solution is a severe eye and skin irritant which could cause severe eye and skin bums. The diluted (3%) solution is a slight to moderate eye and skin irritant. City water crews and fire department have the required emergency response equipment. Mitigation: No ampoteric metals will be used in the proposed facility. Adequate ventilation will be provided. The proposed facility will be equipped with an emergency eye wash and shower supplied with tempered water. At wells 1,2,3, 8 and 9 emergency eye washes with tempered water will be installed. Water crews will be provided with personal protective equipment meeting or exceeding OSHA and Washington L&I standards. During chemical deliveries the approach routes to the delivery area will be coned off. Combination eye and face washes with tempered water will be provided at each well house. These mitigation measures have been incorporated into the design, plans, and specifications for the project. 6. Noise Impacts: Normal construction noises. Mitigation: Construction work hours will be 8:00 AM to 5:00 PM, 5 days per week - Monday through Friday. These mitigation measures are included in the construction contract special provisions. Z Land Use Impacts: The current use of the site is public park, public community center buildings, Parks Department maintenance compound, and drinking water production wells and treatment facilities and is zoned publicly owned Center Office Residential - COR(P). The property to the west and northwest is SR 405 and Liberty Park and is zoned P-1, Public Use. The property to the east and northeast is Maple Valley Highway and a motel and restaurant on property zoned CA, Commercial Arterial. The property to the south and southeast is the Stoneway concrete plant and is on property zoned COR. The property to the south and southwest is currently vacant and is zoned RC, Resource Conservation and P-1. There are the following structures on the site: 1) City of Renton Recreation Center (foot print = approximately 37,500 square feet), 2) City of Renton Cargo Theater (foot print = approximately 9,400 square feet), 3) Parks maintenance building (approx. 1,750 square feet), 4) Parks maintenance building (approx. 1,500 square feet), 5) Parks maintenance building(approx. 1,200 square feet), 6)Well House 8 (approx.: 420 square feet), 7) Fluoridation Building (approx.: 875 square feet), 8)Well House 9 (approx.: 490 square feet),and 9)two picnic shelters (approx. 530 square feet each). The site is within the City of Renton Aquifer Protection Area,Zone 1. Mitigation: The proposed building is sited adjacent to similar facilities at the far edge of the park. Its architectural features will be compatible with the adjacent structures. The Master Application for this project includes an application for a conditional use permit. The materials specified for the construction comply with the Aquifer Protection Ordinance. •City of Renton-PB/PW Department E mental Review Committee Staff Report CORROSION CONTROL TREATMENT.tACILITIES-CEDAR RIVER PARK LUA-97-0I3,ECF REPORT AND DECISION OF(INSERT DECISION DATE) Page6 of 6 8 Aesthetics Impacts: The proposed building will be sixteen feet, five inches in height. The exterior walls will be stacked bond,tan concrete masonry units matching those of the adjacent fluoridation treatment building. The roof will be a sloped, standing seam metal roof matching that of the adjacent building in color (rust/brick) and appearance. The view of the side''of the retaining wall for SR 405 will be obstructed. Mitigation: The exterior of the building will match that of the adjacent fluoridation and Well House 9 buildings. The floor of the containment area will be depressed to control the overall height of the building. The upper portion of the roof will have a smaller slope in order to control the overall height of the building. 9. Light and Glare Impacts: There may be a minor amount of glare off of the roof. It would mainly occur around sunrise and sunset. There is a remote possibility the glare could shine in the direction of traffic on SR 405. Mitigation: The finish for the standing seam metal roof will be satin or flat in order to reduce the possibility of glare. 9. Recreation Impacts: The proposed facility is located at the western edge of the City of Renton Cedar River Park. Mitigation: The City of Renton Water.Utility and its consultant for the design of the project have.worked closely with the City Parks Department and Parks Board to minimize the impact of the facility on the activities•in the Park. The proposed facility is located adjacent to other similar drinking water supply and treatment facilities. The facility was sited as far to the edge of the park as the right-of-way for SR 405 permits. The delivery route was chosen to minimize traffic within the park as well as limiting exposure of park occupants to the delivery truck. 10. Transportation Impacts: The site is served by Houser Way North and Maple Valley Highway. Access to the proposed building is from Maple Valley Highway along the existing drive from Maple Valley Highway to Well House 9 (running along the northeast and northwest perimeter of the Park). The existing drive will be extended to the proposed building. One pick- up truck trip per day is anticipated. During the fall, winter and spring there will be approximately one delivery of sodium hydroxide every four to six weeks. During the summer months the delivery of sodium hydroxide could be as frequent as once a week. There will be one delivery of ortho polyphosphate every six months. It is anticipated that the chemicals will be delivered in 4,000 gallon tanker trucks. This is a tractor/trailer rig 55 to 60 feet long. Mitigation: The chemical storage tanks have been sized to minimize the number of deliveries. E.

REVISED 1/95 PROJECT NARRATIVE Project W-2238 CONSTRUCT DRINKING WATER CORROSION CONTROL TREATMENT FACILITIES Cedar River Park Site Project Purpose. The purpose of the proposed project is to comply with the Lead and Copper Rule , of the Safe Drinking Water Act. Currently, the City's drinking water is corrosive, leading to the leaching of copper from customers' plumbing. The measured levels of dissolved copper at customer taps exceed the level which requires action by the City to lower the levels. The proposed project will reduce the levels of dissolved copper at customer taps. This will be accomplished by raising the pH of the treated water by adding sodium hydroxide and by adding ortho polyphosphate as a corrosion inhibitor. A report describing the project and the method for treating the water has been submitted to and approved by the State of Washington Department of Health. Proposed Improvement Scope. The proposed project includes the construction of a 37' wide by 51' long by 16' high building to house storage tanks and dosing equipment, approximately 1,620 square yards of asphalt paving, approximately 350 linear feet of curbing, approximately 1,370 linear feet of containment casing with chemical solution lines, approximately 720 linear feet of storm water lines with 5 manholes plus 3 wet vaults for solids and floatables removal, approximately 240 linear feet of sanitary sewer lines,approximately 250 linear feet of buried electrical service line, approximately 650 square yards of sod, and approximately 1,150 square yards of pavement restoration. No trees will be cut down. Landscaping will consist of the installation of sod and irrigation sprinklers. Currently 38.0 per cent of the site is covered with impervious surfaces. After completion of the project 39.9 per cent of the site will be covered with impervious surfaces. Current Use of Site. The proposed construction will be located along the western edge of the Cedar River Park. The park land is currently used for indoor and outdoor recreation, parks maintenance, and drinking water production and treatment. Existing improvements include the Renton Community Recreation Center, the Carco Theater, Wellhouse 8, Wellhouse 9, a fluoridation treatment building, three parks maintenance buildings, a softball field,two picnic shelters,roadways and parking lots. Adjacent Water Area. The Cedar River lies to the south of the site. The proposed treatment building is approximately 680 feet from the river. The proposed chemical solution line comes within 90 feet of the river at its closest point. Obstruction of Views. The proposed treatment building will be adjacent to the retaining wall for I- 405. No views will be obstructed. Project Cost. The estimated cost of the project at the Cedar River Park site is $1,155,700. The estimated fair market value is $1,155,700. Proposed Construction Dates. The proposed construction start date is April 1997. The proposed construction completion date is December 1997. REC WED JAM.2 9 1997 DEVELOPMENT PLANNING CITY OF RENTON DRINKING WATER CORROSION CONTROL TREATMENT FACILITIES CEDAR RIVER PARK SITE JUSTIFICATION FOR CONDITIONAL USE APPROVAL A. Comprehensive Plan The construction of the corrosion control treatment facilities is compatible with the general objectives and policies found in the City of Renton Comprehensive Plan. Objective U-D of the Plan is to "Provide, protect and maintain a consistent, ample and safe water supply for the City and future service areas." This project addresses the health issue of dissolved copper in the water at customer taps. B. Community Need The purpose of the proposed project is to comply with the Lead and Copper Rule of the Safe Drinking Water Act. Currently, the City's drinking water is corrosive, leading to the leaching of copper from customers' plumbing. The measured levels of dissolved copper at customer taps exceed the level which requires action by the City to lower the levels. The proposed project will reduce the levels of dissolved copper at customer taps. This will be accomplished by raising the pH of the treated water by adding sodium hydroxide and by adding ortho polyphosphate as a corrosion inhibitor. A report describing the project and the method for treating the water has been submitted to and approved by the State of Washington Department of Health. C. Effect on Adjacent Properties Adjacent properties include parks, State Route 405, State Route 169, Houser Way North, commercial arterial properties, a concrete plant, and resource conservation properties. Within Cedar River Park the adjacent facilities are Wellhouse 9, the fluoridation facility, Wellhouse 8, a softball field and the Recreation Center. Within Liberty Park the adjacent facilities are Wellhouse 1/2/3 and the bathhouse. During construction there could be increased levels of dust and noise, but upon construction completion,there should be no adverse impacts on the adjacent properties.

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.

The proposed project includes the construction of a 37' wide by 51' long by 16' high building to house storage tanks and dosing equipment, approximately 1,620 square yards of asphalt paving, approximately 350 linear feet of curbing, approximately 1,370 linear feet of containment casing with chemical solution lines, approximately.720 linear feet of storm water lines with 5 manholes plus 3 wet vaults for solids and floatables removal, approximately 240 linear feet of sanitary sewer lines, approximately 250 linear feet of buried electrical service line, approximately 650 square yards of sod, and approximately 1,150 square yards of pavement restoration. The purpose of the proposed project is to comply with the Lead and Copper Rule of the Safe Drinking Water Act. Currently, the City's drinking water is corrosive. The measured levels of dissolved copper at customer taps exceed the level which requires action by the City to lower the levels. The proposed project will reduce the levels of dissolved copper at customer taps. This will be accomplished by raising the pH of the treated water by adding sodium hydroxide and by adding ortho polyphosphate as a corrosion inhibitor. 12. Location of the proposal.

The project is located south of Maple Valley Road, east of I-5 and north of the Cedar River, and is within the boundaries of the Cedar River Park and the City of Renton's (City) Community Recreation Center, as shown on Exhibit 1-1. The project is located within the Cedar River Drainage Basin. It is located within Section 17, Township 23 N, Range 5 E. The project will improve 0.36 acres of pervious area into impervious area. The project area is comprised of a flat, grassy area which drains into an existing piped drainage system, which then discharges into the Cedar River. The project is within the City Aquifer Protection Area, Zone 1. This project has been design according to the requirements the City of Renton Aquifer Protection Ordinance No. 4367. In addition, the project will be designed in accordance with the City's Storm and Surface Water Ordinance No. 4260, Chapter 22, Title IV. 1.1 Existing Drainage System and Problems The existing drainage system consists of a piped conveyance system which was built as part of the City's Community Recreation Center in 1988. A downstream analysis was performed on the existing drainage system using the Rational Method for both the 25- and 100-year storms. See Table 3.1 for the downstream drainage calculations. Portions of this system do not have adequate capacity to carry a designed will be 25- year storm. Therefore, the runoff from this project to meet the peak rate runoff control requirements of the King County Surface Water Design �VIanual. 1.2 Proposed Drainage System The proposed drainage system will consist of a stormdrain pipe system and detention/water quality facilities. Existing problems will be improved by this project. The detention system will contain 925 cubic feet. The water quality facility will contain 711 cubic feet. The proposed drainage system is designed to meet the King County Surface Water Design Manual (Revised December 1995), and the aforementioned City Ordinances. Overview 1-1 Final Draft\46260\secl.doc February 5, 1997 1.3 Mitigation Measures The following measures will be taken to lessen and prevent damage to the environment: ❑ Detention facilities will be provided to match existing flow rates from the Project. ❑ Water Quality facilities will be provided at the outlet from the project.

Upstream basins have been delineated and analyzed. Downstream systems have been analyzed to the point of discharge to the Cedar River. ❑ Runoff Control (1.2.3): • Peak Rate Runoff Control: This subject is addressed in Section 4. Detention will be provided to reduce flow rates below the existing 2-, 10-, and 100-year storm event levels. This will be achieved by the construction of a detention facility to control release of water from the site and produce peak controlled discharge rates from the projects runoff at below existing levels. • Biofiltration: Biofiltration has not been provided because it is not allowed according the City's Aquifer Protection Program. Instead, a Wet Vault will be installed to provide water quality treatment. This subject will be further addressed in Section 4. ❑ Conveyance Facilities (1.2.4): This issue is covered in Section 5. ❑ Erosion/Sedimentation Control Plan (1.2.5): The project will need to construct sediment controls. ❑ Maintenance and Operation (1.2.6): Since this is a City of Renton facility, the City will assume maintenance of all drainage facilities and systems. ❑ Bonds and Liability (1.2.7): N/A Conditions Summary 2-1 Final Draft\46260\secl.doc February 5, 1997 2.1.2 Special Requirements ❑ Critical Drainage Areas (1.3.1): This project is within the City of Renton Aquifer Protection Program, Zone 1. ❑ Compliance with an Existing Master Drainage Plan (1.3.2): There are no master drainage plans covering the project site. ❑ Conditions Requiring a Master Drainage Plan (1.3.3): The q g g project does not require a master drainage plan. ❑ Adopted Basin or Community Plan (1.3.4): There is currently no adopted basin plan covering this project. ❑ Special Water Quality Controls (1.3.5): The project will not increase impervious area subject to vehicular use by one or more acres. ❑ Coalescing Plate Oil/Water Separators (1.3.6): The project will not increase impervious areas subject to vehicular use by five acres or more. ❑ Closed Depressions (1.3.7): The project is not tributary to any closed depressions. ❑ Use of Lakes, Wetlands, or Closed Depressions for Peak Rate Runoff Control (1.3.8): The project will not use a lake, wetland, or closed depression for peak rate runoff control. ❑ Delineation of 100-Year Floodplain (1.3.9): The project is not within any Federal Emergency Management Agency (FEMA) designated floodplain. ❑ Flood Protection Facilities for Class 1 and 2 Streams (1.3.10): There are no existing or proposed flood protection facilities for Class 1 and 2 streams within the project. ❑ Geotechnical Analysis and Report (1.3.11): A geotechnical analysis has not been performed for the project. ❑ Soils analysis and report (1.3.12): Soils in the area have been mapped by the Soil Conservation Service, King County Soils Report. Conditions Summary 2-2 Section 3 OffSite Analysis ECONOMIC AND ENGINEERING ([5 SERVICES; INC. " Final Draft\46260\sec3.doc February 5, 1997 Section 3 Off-Site Analysis 3.1 Downstream Analysis Detailed information relating to this analysis is contained in Appendix A. The existing drainage system consists of a piped conveyance system which was built as part of the City of Renton's Community Recreation Center in 1988. A downstream analysis was performed on the existing drainage system using the Rational Method for 25- and 100-year storms. Portions of this system do not have adequate capacity to carry a 25-year storm. The existing tributary area draining to the existing outfall is 6.82 acres and the proposed project will develop approximately 0.35 acre of the 6.82 acres. From the existing point of connection, there are seven pipe segments (615 lineal feet) to the outfall to the Cedar River. Six of these pipe segments (590 lineal feet) do not have sufficient capacity to carry a 25-year storm event. Therefore, the runoff from this project will be designed to meet the peak rate runoff control requirements of the King County Surface Water Design Manual. The Renton Corrosion Control Facility proposes to connect to an existing drainage system built in 1988 for the Renton Community Recreation Center (our analysis follows). The King County Surface Water Design Manual was first published in 1990. Prior to 1990, storm drainage systems may have been designed for the 10- year storm. This probably explains why the existing drainage system is under !capacity (i.e., can not carry a 25- or 100-year storm). As part of our analysis, we have calculated the flows and backwater elevations for both the 25- and 100-year storm events. From our analysis, the existing system is surcharged for the 25-year storm event and over-tops the existing catch basins in the vicinity of the Recreation Center for the 100-year event. The overflow route for the 100-year storm event will follow the paved roadway in a southwesterly direction towards Houser Way, over top the curb at the lowest place in the road, and then sheet flow into the Cedar River.

The drainage system will consist of stormdrain pipes which will discharge into the wet vault and then into the detention system. 4.2 Detention Performance Requirements/Water Quantity Control A hydrologic analysis has been performed to determine the volume of stormwater required for the City Corrosion Control Treatment Facility to discharge into the existing storm drainage system at the Renton Community Recreation Center site. The volume required is 925 cubic feet for the 100-year storm event. This is the amount of volume which will be detained in order for the uncontrolled post developed 100-year peak flow rate of 0.35 cfs to be reduced to match the pre- developed 100-year flow rate of 0.18 cfs. The developed area of the facility is 0.35 acres (15,224 square feet). The stormwater will be stored (detained) in 61 linear feet of 24-inch diameter pipe and 334 linear feet of 18-inch diameter pipe. The alignment will run to the west side of the existing 15-inch diameter pipe in the west parking area of the Recreation Center. The detention system will discharge into an existing manhole which is just downstream of the Recreation Center's oil/water separator. The point of connection was selected for several reasons: 1) It has the lowest 100- year hydraulic grade line; and, 2) Allows for discharge into the existing storm drainage system when the Cedar River is at a 100-year flood stage. The following are the release rates for this project, as determined by the existing hydrographs. The 2-year developed runoff controlled to the 2-year existing condition, the 10-year developed held to the 10-year existing, and the 100-year developed held to the 100-year existing. See Table 4-1.

The Hydra program, by Pizer Incorporated, Inc., was used in the design of the detention system and wet vault for this project. Table 4-2 lists the required storage for the Detention System. Table 4-3 lists the required dimensions for the detention structure. 4.3 Water Quality Control ;The Water Quality (Wet Vault) facility for the project will be placed upstream of the detention facility. The wet vault has also been sized based on the King County Surface Water Design Manual, Special Requirement No. 5. The required water surface area in the wet vault is 1 percent of the developed impervious area, which would be 152 square feet. The required volume is the amount of runoff volume produced by 1/3 of the 2-year, 24 hour precipitation (0.67 inches). This results in a volume of 598 cubic feet. The total required wet vault size would then be 5 feet wide, 31.5 feet long with a depth of 4 feet. This would be located just upstream of the 18-inch diameter detention pipe.
