The detention pond will occupy about 110' x 270' feet (0.68 acres) of the site and will be about 6 feet deep. The existing stormwater system in SE 116th St., NE 10th St., and Anacortes Ave. NE will be replaced with a new system. The new system will connect from the new detention pond to part of the existing system in; Anacortes Ave. NE. depending on engineering design, the new system either will be constructed in NE 10th PL (Alternative 1), or up Anacortes Ave. NE and NE 11th St. (Alternative 2). At the end of each Alternative the new system will connect into the existing system. Project construction is proposed between May 1st and October 31st of 2003 and may extend into the Summer of 2004. Hours of construction are proposed to be Monday through Friday between 7:00 am and 5:00 p.m. A Traffic Control Plan is required to be filed with the city by the contractor to identify hauling routes and traffic control measures for the construction area. Several local streets in the construction area may be limited to one lane during construction. Local access and driveway access will be maintained, except when construction crosses a driveway. B.

There are existing constructed storm water facilities along the frontage of SE 116th street. D. ENVIRONMENTAL IMPACTS 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. 1. Earth Impacts: Excavation to construct the proposed utility trenches could result in erosion. About 6,000 to 9,000 cubic yards of soil may be excavated to form the detention pond and is proposed to be transported offsite (see further discussion in Transportation section). Additionally, 1,200 to 1,800 cubic yards of soil may be placed as backfill (imported) for the new/replacement stormwater lines. The imported backfill will be supplied via the contractor from licensed gravel pits for the stormwater line trenches. The applicant indicates that one to three of the large maple trees located in the southeast corner of the detention pond site may be removed depending on the extent of the pond excavation. Several other trees may be removed to repair the system in the Whitman Court area. On the detention pond site, the majority of the vegetation will be removed for construction of the pond (includes grass, shrubs and blackberries). All wetland plants in the Class 3 wetland are proposed to be removed. All disturbed areas not used for the pond, access road and associated features are proposed to be seeded with native grass for long-term erosion control. Shrubs will be planted along the west and south perimeter of the pond property. The site for the detention pond slopes downward from east to west at approximately a 12% grade. The site will be graded to form the detention pond. According to the Soil Survey of King County Area, the dominant soil on the property is Alderwood gravelly sandy loam and Arents-Alderwood Material. The applicant proposes to utilize measures to minimize potential erosion impacts (storm drain inlet protection, silt fences, hydroseeding and replanting) per the King County Surface Water Manual. Soil stockpiles not in use will be covered during rainy periods. It appears the applicant will utilize measures to reduce potential erosion impacts to the site; therefore, no further mitigation measures are recommended. Mitigation Measures: No further mitigation is recommended. ercrpt.doc City of Renton P/B/PW Department Envirc nal Review Committee Staff Report DETENTION POND/PIPE REPAIR L UA-02-119,ECF REPORT AND DECISION OF NOVEMBER 26,2002 Page 4 of 6 Policy Nexus: N/A 2. Air Impacts: A large quantity of earth will be excavated, moved and removed during the construction process. The applicant indicates that if dust conditions develop, the contractor would use a water truck to reduce blowing dust. Dust and exhaust from construction equipment will occur during the project. Maintenance activities will cause temporary emissions from construction equipment. The applicant has indicated the contractor will ensure emissions are kept to a minimum by maintaining truck and construction equipment mufflers and exhaust systems. Mitigation Measures: No further mitigation is recommended. Policy Nexus: N/A 3. Wetlands/Surface Water Impacts: A Wetland Delineation and Classification Report, prepared by CH2MHILL and dated October 2001, was submitted with the land use application. Two wetlands were identified; one on the detention pond site and one off site (located north of the detention pond) in King County. The wetland located on the proposed detention pond site is a Class 3 wetland according to King County classifications. It is 3,070 square feet in size and is hydrologically isolated as identified in the Wetland Report. The off-site wetland has been determined to be a Class 2 wetland and is required to have a 50 foot buffer, which the applicant is. proposing. The Class 3 wetland located within the proposed detention pond, according to King County code 21A.24.330.H.2., may be used for a detention facility if the following criteria is met: a) a public agency and utility exception is granted pursuant to K.C.C. 21 A.24.070; b) all requirements of the Surface Water Design Manual are met; c) the use will not alter the rating or the factors used in rating the wetland; d) the proposal is in compliance with the latest adopted findings of the Puget Sound Wetlands Research Project; and e) there are no significant impacts to the wetland. The Class 3 wetland has been described as isolated with low biological support. The applicant sent the Army Corps of Engineers a copy of the Wetland report to request a determination of the regulation of the onsite wetland. On October 8, 2002, the Corps issued a determination stating that the onsite wetland was isolated, was not under Corps regulatory jurisdiction and would not need a Corps permit for the proposed work. Construction is proposed within 200 feet of the Class 2 wetland (King County Classification) located north of the detention pond property. The wetland buffer area (50 feet) on the detention pond property will need to be crossed by construction equipment during construction. Silt fencing is proposed to help protect the offsite wetland. After construction, the existing vegetation will be removed from the buffer area and will be replanted with native vegetation. It appears the applicant proposes to utilize measures to reduce potential impacts to the wetlands; therefore, ho further mitigation measures are recommended. The wetlands will be required to be protected according to King County Wetland Development Standards (i.e. buffer, permitted alterations, permits/exemptions). Mitigation Measures: No further mitigation is recommended. Policy Nexus: N/A ercrpt.doc City of Renton P/B/PW Department Envin ntal Review Committee Staff Report DETENTION POND/PIPE REPAIR LUA-02-119,ECF REPORT AND DECISION OF NOVEMBER 26,2002 Page 5 of 6 4. Storm Water Impacts: Stormwater runoff into the new detention pond will come from the existing system in SE 116th St., which serves the areas east of the pond. Those areas include open fields, single-family residences, and City and County rights-of-way. Discharge from the new pond will go into the existing system in SE 116th St./NE 10th St. where stormwater currently goes. The existing system runs about 1700 feet to the north in NE 11th PL and Whitman CT, and eventually connects to a culvert in Whitman CT that Honey Creek flows into. Honey Creek flows into May Creek, which flows to Lake Washington. The total amount of stormwater flowing from the detention pond to the existing system is not expected to change. The detention pond is designed to reduce the duration of the peak flow rates from the 2-, 10-, and 25-year storm events by storing part of the runoff water and discharging it at a slower rate. Computer flow modeling predicts that the pond and pipe improvements will reduce the duration of flooding in NE 10th St. from 11 hours to 0 hours for the 25-year, 24-hour storm event. The applicant indicates that the frequency and severity of flooding in City streets is expected to decrease with the detention pond in service. The detention pond is not expected to create new storm water impacts. The detention pond will probably help reduce the amount of sediment in the stormwater runoff. The outflow system in the pond will include down turned elbows that act as an oil/water separator. The pond may help contain liquid spills in the street and aid in cleanup before a spill reached Honey Creek. The proposed project's objective is to reduce the impacts of storm water (flooding) in streets and homes which mitigates potential impacts. Mitigation Measures: No further mitigation is recommended. Policy Nexus: N/A 5. Ground Water Impacts: According to the applicant, there is a shallow groundwater table, approximately 4 to 10 feet below the ground surface and perched on glacial till. There is also a deeper groundwater table located 30 feet below the ground surface. Depending on the time of year and the groundwater table, a small amount of groundwater may drain into the detention pond but is not anticipated to adversely affect the capacity or'function of the detention pond. The site is located in an Aquifer recharge area that would be designated as Aquifer Protection Area (APA) Zone 2 if it fell within the jurisdictional boundary of the City of Renton. Staff recommends that the site be subject to additional requirements of the APA Zone 2, per City code to mitigate any potential impacts to the aquifer. Some of those requirements include: Construct secondary containment may be required if more than 20 gallons of regulated hazardous materials will be present at the new facility (RMC 4-3-050H2d(i)). A fill source statement (RMC 4-4-060L4) is required if more than 100 cubic yards of fill material will be imported to the project site. Construction Activity Standards (RMC 4-4-03007) shall be followed if ;during construction, more than 20 gallons of hazardous materials will be stored on site or vehicles will be fueled on site. Surface Water Management Standards (RMC 4-6-030E2 and 3)-- Biofilters, stormwater conveyance, and water quality ponds may require a groundwater protection liner. Impervious surfaces shall be provided for areas subject to vehicular use or storage of chemicals. This is not intended to be a complete list of the APA requirements nor does this information substitute for the full ordinance, it is only intended to guide the applicant to the City of Renton code book. Mitigation Measures: The applicant shall be required to adhere to the requirements of the City of Renton Aquifer Protection regulations including but not limited to regulation of hazardous materials; a fill source statement; and surface water management standards. ercrpt.doc City of Renton P/B/PW Department Envin rital Review Committee Staff Report DETENTION POND/PIPE REPAIR L UA-02-119,ECF REPORT AND DECISION OF NOVEMBER 26,2002 Page 6 of 6 Policy Nexus: SEPA Environmental Regulations; City of Renton Critical Area Regulations: RMC 4-3-050 Aquifer Protection. 5. Transportation Impacts: The proposal would require the export of 6,000 to 9,000 cubic yards of material and import of approximately 1,200 to 1,800 cubic yards of backfill. Soil import and export would occur via trucks. Provided that separate trips account for export and import, it has been estimated that up to 1,080 dump truck loads of 10 cubic yards each, or an average of 45 truck trips per week could occur during the construction process from May through October (if completed during one year). Several residents have indicated their support of the project but are concerned about the construction work, specifically material and fuel delivery and notice of street closures. A Construction Mitigation description outlining the proposed hauling and transportation routes was submitted with the land use application. Several streets may be reduced to one lane during construction. Access to local driveways would be maintained, except when construction needs to cross the driveway. Renton Municipal Code requires an approved construction mitigation plan including haul routes and hours and a traffic control plan to be filed prior to the issuance of a construction permit. Mitigation Measures: No further mitigation is recommended. Policy Nexus: N/A E.

Subject:, Detention pond and pipe repair; LUA-02-119,ECF I have reviewed the subject Environmental and Development application. The following are my comments related to the environmental impacts, policy, and code-related comments: Please Note: This lot is outside of the City Limits of Renton. Therefore connection to City utilities and services, if any, may be subject to special conditions. Existing i Conditions: • WATER The site is served by City of Renton Water services. This site is located in the 565 Pressure Zone. The static pressure at street level is approximately 68 psi. This site is not located in the Aquifer Protection Area (APA) (However, it would be mapped as APA zone 2 if it was inside the City Limits). There is a hydrant available at the frontage of this site. SEWER A 8" sewer main exists in SE 116th Street. Connections to this line are subject to conditions for sewer service outside the City limits of Renton. STORM There are existing constructed storm water facilities along the frontage of SE 116th street. STREETS No curb, gutter or sidewalk improvements exist along the frontage of this site. CODE REQUIREMENTS Note: System Development Charges may be applicable if this project makes connection to City services. Because no connections were proposed in the project description or preliminary plans, no fees were calculated. If connection is made then code required fees would apply. WATER , No fees if not connecting to City Water. SANITARY SEWER No fees if not connecting to City Sewer. • • 1-I:1Division.s\Develop.serlDev&plan.ing\PROJECTS\02.119.susan\Plan Review GF.doc SURFACE WATER No fees; project is outside city limits. TRANSPORTATION No fees; project is outside city limits. RECOMMENDED CO ONS i Prior to any construction activities on the site, Temporary Erosion and Sedimentation Control (TESC) shall be installed and maintained to the satisfaction of the representative of the Develop nt Services Division for the duration of the project. . Install a silt fence along the downs eter of the area that is to be disturbed. The silt fence shall be in place before clearing and gra in 's-i sated, and shall be constructed in conformance with the specifications presented in of the in County Surface Water Design Manual. This will be required during the construction of both of -s' d on-site improvements. 3. The site is located in an Aquifer recharge area that would be designated as Aquifer Protection Area (APA) Zone 2 if it fell within the Jurisdictional boundary of Renton. It is therefore recommended that it be subject to the additional requirements for APA Zone 2, per City code. Some of those requirements include: Constructed secondary containment )* may be required if more than 20 gallons of regulated hazardous materials will be present at the new facility (RMC 4-3-050H2d(i)). A fill source statement (RMC 4-4-060L4) is required if ,; • more than 100 cubic yards of fill material will be imported to the project site. Construction Activity Standards (RMC 4-4-03007) shall be followed if during construction, more than 20 gallons of hazardous materials will be stored on site or vehicles will be fueled on site. Surface Water Management Standards (RMC 4-6-030E2 and 3)--Biofilters, stormwater \ / conveyance, and water quality ponds may require a groundwater protection liner. Impervious surfaces shall be provided for areas subject to vehicular use or storage of chemicals. This is not intended to be a complete list of the APA requirements nor does this information substitute for the full ordinance, it is only intended to guide the applicant to the City of Renton code book. fig► U H:\Division.s\Develop.ser\Dev&plan.ing\PROJECTS\02-119.susan\Plan Review GF.doc City of Rc.:-_.7 Department of Planning/Building/Public cs ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET REVIEWING DEPARTMEN COMMENTS DUE: NOVEMBER 13, 2002 APPLICATION NO: LUA-02-119, ECF DATE CIRCULATED: • • .v APPLICANT: Daniel Carey PROJECT MANA PROJECT TITLE: Detention Pond/Pipe Repair WORK ORDER NO: 77049 LOCATION: Various:City ROW in NE 10th St.to NE 11th St.,Anacortes Ave. NE, King County ROW &site at 13610 SE 116th St. SITE AREA: Pond Only—49,036 sq.ft.

Signature of Director or Authorized Representative Date Routing Rev.10/93 CITY OF RENTON ECONOMIC DEVELOPMENT NEIGHBORHOODS, AND STRATEGIC PLANNING MEMORANDUM DATE:, November 12,2002 TO: Susan Fiala FROM: Rebecda Lind STAFF CONTACT: Don Erickson SUBJECT: New Detention Pond/Pipe Enlargement&Repair, City ROW in NE 10th St. to NE 11th St.,Anacortes Avenue NE; LUA-02-119, ECF The applicant,Renton Storm Water Utility, is proposing to construct a stormwater detention pond on a 142 acre parcel of undeveloped property in King County that is owned by the City. The applicant has applied for permits in Renton and King County for this proposed action. As the project proponent, the City apparently is the lead agency under SEPA for both the construction within the city as well as that in King County. In addition to the new detention pond the existing stormwater system in SE 116t Street,NE 101 Street, and Anacortes Avenue NE will be replaced with a new system that will connect into the new detention pond. The intent of this project is to reduce the frequency and severity of flooding in NE 10th Street, Anacortes Avenue NE, and Anacortes Court NE. The subject site of the detention pond is within Renton's PAA and presumably would be annexed into the City with the next few years. The parcel the detention pond is sited on is designated Residential Single Family on the Renton Comprehensive Land Use Map and is zoned R-6 — Residential 6 du per acre in the County. Relevant City Comprehensive Plan Utility Policies: Policy U-13. Coordinate the extension of utility services with expected growth and development. Policy U-17. Timely and orderly extension of City provided utility services (water, sanitary sewer, surface water, solid waste) should be provided within the City's existing and future service areas to meet public health and safety requirements. Policy U-20. All development should be required to pay an equitable share of construction costs for improvements to utility systems for water, sanitary sewer and stormwater necessitated by that development. When utility improvements will provide a general public benefit, the City may contribute funds for the construction of improvements to utility systems to,support the public interest. Policy U-26. In the event of a threat to public health and safety, the City utilities may use utility resources to prevent or mitigate such threats. NE 10th St/Anacortes Avenue i. Detention Pond&Storm System Impro Project 2 11/12/02 Analysis: The subject work appears necessary to mitigate flooding along NE 10th Street, Anacortes Avenue NE, and Anacortes Court NE. Since this area was annexed into the City in 1962, it is unlikely that the same development standards that apply today applied back then. It appears that the proposed improvements will help mitigate a potential threat to the public health and safety (Policy U-26). Recommendation: Support the upgrading of the stormwater system in the vicinity of Whitman Court NE, Anacortes Avenue NE, and NE 10th Street, including the construction of larger stormwater pipes and a 0.68 stormwater detention pond on a parcel on the north side of SE 116th Street abutting the City. cc: Don Erickson Document2\d • ` City of Rci::.i.i Department of Planning/Building/Public :..,,.cs ENVIRONMENTAL & DEVELOPMENT APPLICATION REVIEW SHEET REVIEWING DEPARTMENT: �� re_ Pr 2 J2n t\0A COMMENTS DUE: NOVEMBER 1 2 , 2 _ „ 1 ll _ Vi LE i�` APPLICATION NO: LUA-02-119, ECF DATE CIRCULATED: OCTOBEF�I QlOJI 1; APPLICANT: Daniel Carey PROJECT MANAGER: Susan Fiala� I;I i Li PROJECT TITLE: :Detention Pond/Pipe Repair , WORK ORDER NO: 77049 ` J.

Furthermore, the City's use of its Development Services Division for the SEPA review conforms to part"C" of WAC 197-11-926 where agency people (Renton's Development Services Division)responsible for the SEPA review should be different then the agency people (Renton's Surface Water Utility)making the proposal.

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.

King County Conditional Use Permit(may be needed). 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. The project involves constructing a detention pond to store stormwater runoff, constructing new and replacement stormwater pipe systems for the pond, and repairing and upgrading parts of the existing stormwater system (hereinafter "system"). The purpose of the pond is to reduce the frequency and severity of flooding in NE 10th ST, Anacortes Ave. NE, and Anacortes CT NE. The stormwater detention pond is located on a 1.12 acre parcel of undeveloped property located in King County, and owned by the City of Renton. Surface water runoff from the existing system in SE 116th ST site will be directed into the pond, stored, and released at a slower rate into the existing system west of the site. The detention pond will occupy about 110' x 270' feet (0.68 acres) of the site, and will be about 6 feet deep. On the east side of the pond the cut will be about 15 feet deep because of the slope of the existing hillside. New stormwater pipes will be installed in SE 116th ST to direct flow into and out of the detention pond. The existing stormwater system in SE 116th ST, NE 10th ST, and Anacortes Ave NE will be replaced with a new system. The new system will connect from the new detention pond to part of the existing system in Anacortes Ave NE. From there, depending on engineering design, the new system either will be constructed in NE 10th PL (Alternative 1), or up Anacortes Ave NE and NE 11th ST (Alternative 2). At the end of each Alternative the new system will connect into the existing system. The existing systems consist of 8- to 18-inch stormwater pipes. The new system will consist of approximately 12-to 30-inch diameter pipes. Approximately 1400 to 1800 feet of pipe, and new manholes and catch basins, will be installed. The exact pipe size and location of the new system will be finalized after the design work is completed. In Whitman CT NE,the existing system will be replaced at two locations with a new system intended to reduce maintenance problems. In the 1100 block of Whitman CT NE the existing 15- to 18-inch stormwater pipe has problems with joint separation and root intrusion and blockage. The existing pipe will be replaced by a new 24- to 30-inch pipe that will resist root intrusion. Approximately 50 to 200 feet of pipe, and new manholes and catch basins,will be installed. In the 1200 block of Whitman CT NE the existing system was constructed as an 18-inch vertical siphon to run under a pair of culverts that Honey Creek use to run through. The siphon is a maintenance problem due to sediment buildup and the difficulty to access the pipe for cleaning. Honey Creek was diverted away from the culverts in about 1980. The abandoned culverts will be removed in the center of the street and the siphon will be eliminated. A new 24- to 30-inch storm water pipe will be installed to replace the 18-inch siphon. Approximately 50 to 100 feet of pipe, and new manholes and catch basins, will be installed. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not H;File Sys\SWP-27-2266\01\1300\01\020709c-SEPA CHKlist v 23.doc\DWC\tb 10/18/02 3 required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project is located in the NW 1/4 of Section 10, Township 23N, Range 5E, in the City of Renton, and in King County,Washington. The project is located in three nearby areas. The detention pond is located on a piece of undeveloped property in King County, next to the City of Renton Corporate Boundary. The property is located on the north side of SE 116th ST, approximately 300 feet east of the intersection with Anacortes Ave NE and 600 feet west of 138th Ave SE. Stormwater system pipe improvements for the detention pond will occur south of the detention pond property in SE 116th ST in the King County ROW. Pipe system improvements will also occur in the City of Renton ROW in the 4300-4400 blocks of NE 10th ST, the 1000-1100 blocks of Anacortes Ave NE, the 4200-4300 blocks of NE 10th PL, and 4200-4400 blocks of NE 11th ST. • Repairs and maintenance to the existing stormwater system will occur in the 1100 block of Whitman CT NE in City of Renton ROW, and in the adjacent apartment building parking lot that the City has an easement over (ORD. No. 2957, Aug 11, 1975). A second maintenance area is in the City ROW in the 1200 block of Whitman CT NE, about 300 feet south of NE Sunset Blvd. B. ENVIRONMENTAL ELEMENTS 1. EARTH a. General description of the site (circle one); flat, rolling , hilly, steep slopes, mountainous, other. Rolling, 5 to 10 % slope on pond site. b. What is the steepest slope on the site (approximate percent slope?) About 12% on the pond site. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The soils are generally common forms of glacial till and are typically silty sands with some gravel. They are classified as Alderwood Gravelly Sandy Loam (AgC) and Arents- Alderwood Material (AmC). d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. About 6,000 to 9,000 cubic yards of soil may be excavated to form the detention pond. About 1,200 to 1,800 cubic yards of soil may be placed as backfill for the new or replacement stormwater lines. The contractor will supply the backfill from licensed gravel pits. H;File Sys\SWP-27-2266\01\1300\01\020709c-SEPA CHK1ist v 23.doc\DWC\tb 10/18/02 4 f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Minor erosion could occur during construction of the detention pond. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? About 2.5 percent (1,200 sf) of detention pond site may be covered with an asphalt access road and pad. About 120 feet of new sidewalk may be constructed along the north side of NE 10th ST and SE 116th ST right-of-ways. Excavations in the existing asphalt roads will be replaced with new asphalt. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Typical erosion control measures such as silt fencing, catch basin inlet protection, hydroseeding, and replanting of the site should reduce and control any erosion from construction activities. 2. AIR a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. During construction, dust and exhaust from construction equipment will occur. After construction, no emissions are expected from the site. Maintenance activities, such as cleaning the pond every 3 to 5 years will cause temporary emissions from construction equipment. b. Are there any off-site sources of emission or odor that may affect your proposal? If so, generally describe. No. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Construction equipment will have mufflers and exhaust systems in good working order. Dust will be kept down by watering the excavation as needed. 3. WATER a. Surface Water: 1) Is there any surface water body on or in the immediate vicinity of the site (including year- round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. One Category 3 wetland is present in the southern half of the detention pond property. The wetland is 3,070 sf in size, and is described as hydrologically isolated in the Wetland Delineation and Classification Report. H;File Sys\SWP-27-2266\01\1300\01\020709c-SEPA CHK1ist v 23.doc\DWC\tb 10/18/02 5 One Category 2 wetland was found on the property north of the detention pond property, and drains to an unnamed tributary noted below. The wetland area within 100 feet of the property line was measured at 1,033 sf. City of Renton Category 2 and 3 wetlands correspond to King County Class 2 and 3 wetlands. There is a small, unnamed tributary about 400-600 feet north of the detention pond property that drains the Category 2 wetland to the upper part of Honey Creek and to May Creek (#0285A, "May Creek Current and Future Conditions Report", King County Surface Water Management Division 1995). Development has occurred on the properties north of the detention pond site, and the northern part of the unnamed tributary has been culverted for residential and business development. In addition, a large portion of Honey Creek north of the project site was culverted 30 to 40 years ago. The culverted portion of Honey Creek located in Whitman CT is about 90 feet from the existing storm pipe and siphon that will be replaced as part of the maintenance work. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. The onsite Category 3 wetland will be removed when the detention pond is excavated. The Wetland Delineation Report describes the Category 3 wetland as an isolated wetland with low biological support. The wetland appears to meet the isolated wetland definition in King County 21A.06.1410. King County regulations allow alterations to wetlands if they do not serve any of the wetland functions as identified in KC 21A.06.1415(KC 21A.24.330). The City sent the Army Corps of Engineers (Corps) a copy of the Wetland Delineation Report and requested a jurisdictional wetland determination to determine if the Corps would regulate the onsite Category 3 wetland. On October 8, 2002, the Corps issued a determination stating that the onsite wetland was isolated, was not under Corps regulatory jurisdiction, and would not need a Corps permit for the proposed work. Construction will be within 200 feet of the Category 2 wetland located north of the detention pond property. King County requires a 50-foot buffer from Category 2 wetlands. The buffer area on the detention pond property will need to be crossed by construction equipment during construction. Silt fencing will be used to help protect the offsite wetland. After construction, the existing vegetation will be removed from the buffer area and it will be replanted with native vegetation. The culverted portion of Honey Creek located in Whitman CT is about 90 feet from the existing storm pipe and abandoned siphon that will be replaced as part of the maintenance work. The abandoned siphon will be removed and replaced with a new 24- to 30-inch diameter stormwater pipe. The exact pipe diameter will be determined for the final plans. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. H;File Sys\SWP-27-2266\01\1300\01\020709c-SEPA CHK1ist v 23.doc\DWC\tb 10/18/02 6 . The entire onsite Category 3 wetland (3,070 sf)will be removed when the detention pond is excavated. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No. 5) Does the proposal lie within a 100-year flood plain? If so, note location on the site plan. No. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground Water: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. There is a shallow groundwater table, about 4 to 10 feet below ground surface, perched on glacial till under the site. The permeability of the glacial till is typically low (estimated at 1x10-4 to 1x10-5 cm/sec). There is also a deeper ground water table about 30 feet below ground surface. Depending on the groundwater level, the detention pond may intercept the shallow groundwater table and some groundwater may drain into the pond. Assuming the ground was saturated during the winter, approximately 2 to 20 gallons per minute (gpm) of groundwater could flow into the entire pond area based on the typical soil permeability. At other times of year when the groundwater table is lower, the inflow amount would probably be less then 2 gpm for the entire pond area. If the glacial till is less permeable, the potential groundwater inflow rate would be less than 2 gpm for the entire pond area. Any groundwater flowing into the pond would either evaporate, infiltrate into a different soil layer, or flow out the pond discharge pipe into the City drainage system. The amount of groundwater that may flow into the detention pond is expected to be insignificant, and not adversely affect the capacity or function of the detention pond. Depending on the groundwater level in the shallow groundwater table and permeability of the glacial till, stormwater in the detention pond could infiltrate into the soil during some parts of the year. As with the inflow scenario, the amount of possible infiltration into the soil is estimated to be low. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals...; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. None. H;File Sys\SWP-27-2266\01\1300\01\020709c-SEPA CHK1ist v 23.doc\DWC\tb 10/18/02 7 c. Water Runoff(including storm water): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters, If so, describe. Stormwater runoff into the new detention pond will come from the existing system in SE 116th ST,which serves the areas east of the pond. Those areas include open fields,single-family residences, and City and County ROW. Discharge from the new pond will go into the same existing system in SE 116th ST/NE 10th ST where stormwater currently goes. The existing system runs about 1700 feet to the north in NE 11th PL and Whitman CT, and eventually connects to a culvert in Whitman CT that Honey Creek flows in. Honey Creek flows into May Creek,which flows to Lake Washington. The total amount of stormwater flowing from the detention pond to the existing system is not expected to change. The detention pond is designed to reduce the duration of the peak flow rates from the 2-, 10-, and 25-year storm events by storing part of the runoff water and discharging it at a slower rate. Computer flow modeling predicts that the pond and pipe improvements will reduce the duration of flooding in NE 10th ST from 11 hours to 0 hours for the 25-year, 24-hour storm event. The frequency and severity of flooding in City streets is expected to decrease with the detention pond in service. 2) Could waste material enter ground or surface waters? If so, generally describe. Any liquid spills in the street could enter the drainage system and new detention pond. The same potential currently exists without the detention pond. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: The detention pond is not expected to create new water impacts. The detention pond will probably help reduce the amount of sediment in the stormwater runoff. The outflow system in the pond will include down turned elbows that act as an oil/water separator. The pond could act to help contain liquid spills in the street, and aid in cleanup before a spill reached Honey Creek. The detention pond will help control stormwater runoff impacts to Honey Creek and May Creek by reduce the duration of the peak flow rates from the 2-, 10-, and 25-year storm events by holding part of the stormwater runoff and discharging it at a slower rate. 4. PLANTS a. Check or circle types of vegetation found on the site: _x_ deciduous tree: alder, maple, aspen, other maple, poplar, other unidentified deciduous trees. evergreen tree: fir, cedar, pine, other x shrubs _x grass H;File Sys\SWP-27-2266\01\1300\01\020709c-SEPA CHK1ist v 23.doc\DWC\tb 10/18/02 8 • pasture crop or grain _x_ wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other slough sedge,soft rush, daggerleaf rush water plants: water lily, eel grass, milfoil, other _x_ other types of vegetation blackberry, bentgrass, misc. grass and shrubs b. What kind and amount of vegetation will be removed or altered? On the detention pond property the majority of the vegetation will be removed for construction of the pond. That includes grass, brush, shrubs, and blackberries. All wetland plants in the Category 3 wetland will be removed. Depending on the extent of the pond excavation needed, one to three of the large maple trees (42", 36", and 36" diameter) in the southeast corner of the site may be removed. In the easement in the apartment building parking lot north of Whitman CT about 2 to 4 poplar trees may need to be removed to replace the existing stormwater pipe. c. List threatened or endangered species known to be on or near the site. None known. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: All disturbed areas not used for the pond, access road, and associated features will be seeded with native grass for long-term erosion control. Shrubs will be planted along the west and south perimeter of the pond property. After construction is completed the existing vegetation in the 50-foot wetland buffer will be removed and the buffer area will be replanted with native vegetation. 5. ANIMALS a. Circle any birds and animals, which have been observed on or near the site or are known to be on or near the site: Birds: hawk, heron, eagle, songbirds, other . small birds in general Mammals: deer, bear, elk, beaver, other Typical small mammals such as mice and squirrels may be present Fish: bass, salmon, trout, herring, shellfish, other b.

The purpose of the pond is to reduce the frequency and severity of flooding in NE 10th St, Anacortes Ave. NE, and Anacortes CT NE. The stormwater detention pond is located on a 1.12-acre parcel of undeveloped property located on SE 116th St in King County, and owned by the City of Renton. The pond will occupy about 110' x 270' feet (0.68 acres) of the site, and will be about 6 feet deep. Because of the slope of the hill, the east side of the pond will involve a cut of about 15 feet. The existing stormwater systems located in SE 116th St, NE 10th St, and Anacortes Ave NE will be replaced with a new system. The new system will connect from the new detention pond to part of the existing system in Anacortes Ave NE. From there, depending on engineering design, the new stormwater system either will be constructed in NE 10th PL (Alternative 1), or up Anacortes Ave NE and NE 11th St (Alternative 2). At the end of each Alternative the new system will connect into the existing system. The new system will consist of 12- to 30-inch diameter pipes. Approximately 1400 to 1800 feet of pipe, and new manholes and catch basins, will be installed. The exact size and location of the new system will be finalized after the design work is completed. The existing stormwater system located in Whitman CT NE will be replaced at two locations with new systems intended to reduce maintenance problems. In the 1100 block of Whitman CT NE the existing 15- to 18-inch stormwater pipe will be replaced by approximately 50 to 200 feet of new 24- to 30-inch pipe. In the 1200 block of Whitman CT NE the existing system was constructed as a siphon to run under a pair of culverts. The culverts are no longer in use and will be cut and plugged.. The old siphon will be replaced with approximately 50 to 100 feet of pipe of new 24-to 30-inch pipe. The following land use permits may be needed: City of Renton Exemption for Category 3 Wetland less than 5,000 sf in size; U.S. Army Corps of Engineers Wetland Determination (obtained 10/8/02); NPDES Construction Permit (may be needed); Washington State Dept. of Ecology Administrative review for isolated wetlands; King County Clearing and Grading Permit; King County Right-of-Way Use Permit; King County Sensitive Area Review.( may be needed); King County Site Engineering Plan Submittal (may be needed); King County Conditional Use Permit (may be needed). The detention pond property in King County is zoned R-6. The areas around the City of Renton street ROWs are zoned R-8, Residential (Renton). H:File Sys\SWP-28-2266\01\1300\01\020709d-Project Narrative v10.doc\DWC\tb Page 1 In Whitman CT near Sunset Blvd the zoning is CN, Center Neighborhood, and RM-N, Residential Multi-Family Neighborhood Center. The stormwater detention pond is located on a 1.12-acre parcel of undeveloped property owned by the City of Renton. The site is vacant and is covered with a variety of grass, plants, shrubs, and three Maple trees. There are wood and wire fences on the site. The existing stormwater system in SE 116th St is located in King County ROW and is used as an asphalt street. The existing stormwater systems in NE 10th St, Anacortes Ave NE, NE 10th Place, and Whitman CT are located in City of Renton ROW and are used as asphalt streets. Part of the existing system south of Whitman CT is located in a City easement in an apartment building parking lot. A 3,070 sf Category 3 wetland was found in the southern half of the detention pond property. On October 8, 2002, the Corps issued a determination stating that the onsite Category 3 wetland was isolated, was not under Corps regulatory jurisdiction, and would not need a Corps permit for the proposed work. A Category 2 wetland was found just north of the detention pond property. The Category 2 wetland area within 100 feet of the property line was measured at 1,033 sf. City of Renton Category 2 and 3 wetlands correspond to King County Class 2 and 3 wetlands. The soils are generally common forms of glacial till and are typically silty sands. They are classified as Alderwood Gravelly Sandy Loam (AgC) and Arents-Alderwood Material (AmC). The detention pond site drains from east to west. The detention pond property will be used to construct a detention pond to store stormwater runoff. Other work in the right-of-way involves constructing new and replacement pipe systems for the pond, and repairing and upgrading parts of the existing system. Approximately 120 linear feet of new sidewalk may be placed on the north side of NE 10th St and SE 116th St. The sidewalk would extend from the existing walk on NE 10th St to the new detention pond driveway. The estimated construction cost of the detention pond and storm water improvements is $620,000 About 6,000 to 9,000 cubic yards of soil may be excavated to form the detention pond. About 1,200 to 1,800 cubic yards of soil may be placed as backfill for the new or replacement stormwater lines. The contractor will supply the backfill from licensed gravel pits. Depending on the extent of the pond excavation, one to three of the large maple trees (42", 36", and 36") in the southeast corner of the detention pond site may be removed. Two to four poplar trees along the fence line of the apartment building parking lot in Whitman CT need to be removed to repair the system in that area.

Work on weekends is not expected. If work on weekends becomes necessary, it will require approval from the City Project Manager. Proposed Hauling/Transportation Routes: The contractor will probably use 1-405, SR-900 / Sunset Blvd NE, or NE 3rd / 4th ST to reach the site vicinity, and Union Ave NE, Duvall Ave NE / SE 138th Ave, and NE 10th ST/SE 116th ST to reach the construction site. The contractor will be required to file a Traffic Control Plan with the City to identify the hauling routes and traffic control measures for the construction area. SE 116th St, NE 10th ST, Anacortes Ave NE, NE 11th ST, and Whitman CT will probably be limited to one lane while construction is occurring in those streets. Access to local driveways will be maintained, except when construction actually needs to cross a driveway. Measures to Minimize Impacts Erosion control measures such as storm drain inlet protection and silt fences per the King County Surface Water Manual will be used. Any soil stockpiles not in use will be covered with plastic sheets during rainy periods. If dust conditions develop, the contractor will be required to use a water truck to reduce blowing dust. All construction equipment will be required to have muffler and exhaust systems in good working order.

However,if the City purchases the property,the City would annex it before developing the proposed stormwater project.The property,which consists of one parcel,is bounded to the south by NE 10th Street(SE 116th Street),to the east by Chelan Avenue,and to the west and north by residential lots(Figure 2).The site is currently undeveloped. This report is being prepared to help evaluate the feasibility of the site for a proposed stormwater detention pond. Two;wetlands were identified: one on site and one off site.Both exhibited the three parameters characteristic of a wetland(i.e.,soils,vegetation,and hydrology).Wetland B was identified on site,is 3,070 square feet(ft2),and meets the City's criteria for a Category 3 wetland,except that it is less than 5,000 ft2;therefore,the City would not regulate this wetland,but the U.S.Army Corps of Engineers (COE) could.Wetland C was identified off site,is larger than 1,000 ft2,and meets the City's criteria for a Category 2 wetland.Both the City and COE would regulate Wetland C. The City's wetland categories indicate the quality and value of wetlands;the criteria are described later in this report. Possible impacts to Wetlands B and C could result from construction of the proposed stormwater detention pond.

Where access was allowed,wetlands on adjacent properties within 100 feet of the Vuong property were also delineated and classified,as required by City ordinance.Where access was denied,identification and dassification of wetlands on adjacent properties was limited to visual observation from the Vuong property. Field data were collected to support the wetland delineation(Appendix A).Observations of vegetation,soils,and hydrology at representative sample plots(upland and wetland)were documented.Habitat identified as wetland was dassified in the field using Cowardin et al. (1979). 3.2.2 Vegetation Presence of wetland vegetation was determined according to information found in the National List of Plant Species that Occur in Wetlands:National Summary for Region 9(Reed, SEAT:\159867\WETLANDS DEIJNEATION REPOR1\RENTON_WEILAND_FINALDOC 3 - I WETLAND DEUNEATION AND CLASSIFICATION REPORT FOR THE NE 10TH STREET/ANACORTES AVENUE NE STORMWATER SYSTEM IMPROVEMENT PROJECT 1988)and the Supplement to National List of Plant Species that Occur in Wetlands:Northwest (Region 9) (USFWS,1995).These sources assign wetland and nonwetland plants to a range of classifications,based on the prevalence of their occurrence in either wetland or upland areas.A plant's dassification is referred to as its"indicator status" (i.e.,whether it indicates the presence of wetlands). Within a 2-meter radius of each sample plot,dominant plant species were determined for each vegetative stratum:herb,woody vine,shrub,sapling,and tree.Percent cover of most species in a plot was estimated and the indicator status recorded.Dominant species were assigned based on at least 20 percent cover within a stratum.Plots where more than 50 percent of the dominant species were facultative,facultative wetland,or obligate wetland species were considered to have hydrophytic vegetation(Table 1)and,therefore,to meet the wetland vegetation criterion. • TABLE 1 U.S.Fish and Wildlife Service Wetland Indicator Status Wetland Delineation and Classification Report Classification Percent Occurrence in Wetlands Obligate Wetland(OBL) More than 99 Facultative Wetland(FACW) 67 to 99 Facultative(FAC) 34 to 66 Facultative Upland(FACU) 1 to 33 Obligate Upland(UPL) Less than 1 No Indicator(NI) Insufficient data to determine indicator status Source: Reed(1988). 3.2.3 Soils Data on soil texture and color,presence of mottles and/or concretions,organic matter content,moisture content,and presence of oxidized root zones were recorded.Using Mu1isell®color charts,soil matrix,and mottle colors(hue,value,and chroma)were determined immediately below the A horizon,or within the surface(10 inches)if no A horizon boundary occurred before that depth.Munsell®soil colors are reported in the wetland descriptions below in parentheses following the soil color description.Soils with low'c.hromas(i.e.,two with mottles present;one or less independent of mottles)or soils with high organic accumulations in the upper horizon(i.e.,muck or peat layers or heavy organic sta x ing)indicated the presence of wetland or hydric soils and,therefore,meet the wetland soils criterion. 3.2.4 Hydrology Visual observations of soil saturation,surface inundation,visible drainage patterns, deb ris/sediment deposits,and surface scour were recorded.Depth to water in unlined boreholes was measured after allowing sufficient time for water to accumulate.If any of these characteristics were observed,wetland hydrology was considered to exist.

Orange flagging marked numerically("SP-#")was used to mark sample plots where site- specific soils,vegetation,and hydrology data were collected and recorded. 4.0 Applicable Regulations Wetlands regulations applicable(or expected to be applicable) to this project include those of the City,the U.S.Army Corps of Engineers(COE),and the Washington State Department of Ecology(Ecology).The site is currently located in King County;however,if the City decides to purchase it,the City would also annex it,and the site would then fall under the City's jurisdiction.Permitting would vary,depending on the specifics of any project proposed on the subject property.These agencies will ultimately determine the applicability of the regulations. 4.1 City of Renton Wetland Jurisdiction The City's wetland regulations are embodied in their critical areas regulations(Ordinance No.4835,RMC 4-3-050).The purposes of their wetland regulations are to accomplish the following: a. Ensure that activities in or affecting wetlands not threaten public safety,cause nuisances,or destroy or degrade natural wetland functions and values;and b. Protect public health,safety,and welfare by minimizing and managing the adverse environmental impacts of development within and adjacent to wetlands;and • c. Preserve,protect,and restore wetlands by regulating development within them and around them;and d. Protect the public from: (1) Preventable maintenance and replacement of public facilities needed when wetland functioning is impaired;and (2) Costs associated with repair of downstream properties resulting from erosion and flooding due to the loss of water storage capacity provided by wetlands;and (3) Unnecessary costs for public emergency rescue and relief operations;and (4) Potential litigation on improper construction practices occurring in wetland areas; and e. Provide City officials with information to evaluate,approve,condition,or deny public or private development proposals;and f. Prevent the loss of wetland acreage and functions,and strive for a net gain over present conditions. For establishing buffer widths,replacement ratios,and avoidance criteria,the City's ordinance(RMC 4-3-050-B.7.b)requires that wetland categories be designated according to the criteria in Table 2. SEA1E:11598671WETLANDS DELINEATION REPOR11RENTON_WETLAND_FlNALDOC 5 WETLAND DELINEATION AND CLASSIFICATION REPORT FOR THE NE 10TH STREET/ANACORTES AVENUE NE STORMWATER SYSTEM IMPROVEMENT PROJECT TABLE 2 Renton Wetland Categories(per Ordinance 4835,RMC 4-3-050-B.7.b) Wetland Delineation and Classification Report Category Description Category 1: Category 1 wetlands are wetlands which meet one or more of the following criteria: Very High 1. The presence of species listed by Federal or State government as endangered or Quality threatened,or the presence of essential habitat for those species;and/or Wetlands 2. Wetlands having 40 to 60 percent permanent open water(in dispersed patches or otherwise) with 2 or more vegetation classes;and/or 3. Wetlands equal to or greater than 10 acres in size and having 3 or more vegetation classes, one of which is open water;and/or 4. The presence of plant associations of infrequent occurrence;or at the geographic limits of their occurrence;and/or 5. Wetlands assigned the Unique/Outstanding#1 rating in the current King County Wetlands Inventory 1991 or as thereafter amended. Category 2: Category 2 wetlands are wetlands greater than 2,200 ft2 which meet one or more of the following High Quality criteria: Wetlands 1. Wetlands greater than 2,200 ft2 that are not Category 1 or 3 wetlands;and/or 2. Wetlands that have heron rookeries or raptor nesting trees,but are not Category 1 wetlands; and/or 3. Wetlands of any size located at the headwaters of a watercourse,but are not Category 1 wetlands,and/or 4. Wetlands assigned the Significant#2 rating in the current King County Wetlands Inventory 1991 or as thereafter amended;and/or 5. Wetlands having minimum existing evidence of human related physical alteration such as diking,ditching,or channelization. Category 3: Category 3 wetlands are wetlands greater than 5,000 ft2 which meet one or more of the following Lower criteria: Quality 1. Wetlands that are severely disturbed.Severely disturbed wetlands are wetlands which meet Wetlands the following criteria: a. Are characterized by hydrologic isolation,human-related hydrologic alterations such as diking,ditching,channelization,and/or outlet modification;and b. Have soils alterations such as the presence of fill,soil removal,and/or compaction of soils;and c. May have altered vegetation. 2. Wetlands that are newly emerging.Newly emerging wetlands are: a. Wetlands occurring on top of fill materials;and b. Characterized by emergent vegetation,low plant species richness,and used minimally by wildlife.These wetlands are generally found in the areas such as the Green River Valley and Black River Drainage Basin. 3. All other wetlands not classified as Category 1 or 2 such as smaller,high quality wetlands. Category designations for each wetland involved in this project are described below under Wetland Descriptions.Width of buffers required to protect wetlands is based on wetland categories,as shown in Table 3. Activities within regulated wetlands and/or buffers include both activities that directly remove or alter wetlands(e.g.,excavation,filling,placement of pilings or structures,vegeta- 1 SEA1E:11598671WETLANDS DEUNEATION REPORi1RENTON_WETLAND_FINALDOC 6 WETLAND DELINEATION AND CLASSIFICATION REPORT FOR THE NE 10TH STREET/ANACORTES AVENUE NE STORMWATER SYSTEM IMPROVEMENT PROJECT tion removal)and activities that affect wetland functions(e.g.,disturbance of water levels, changes to water temperature or physical characteristics,application of pesticides or other chemicals).In addition to measures to protect directly affected wetlands,the City may require protection measures or erosion control measures to provide protection of a wetland and buffer when any of the regulated activities are proposed on a site,but are not within a wetland and/or buffer.Regional stormwater management facilities operated by the City may receive an exemption from the City wetland regulations and may be located in a critical area or buffer. TABLE 3 Renton Wetland Buffer Requirements Wetland Delineation and Classification Report Wetland Category Standard Width 1 100 feet 2 50 feet 3 25 feet Source: Renton Ordinance No.4835,RMC 4-3-050-M.6. All activities within regulated wetlands and/or buffers must be mitigated according to City Ordinance No.4835 (RMC 4-3-050-M.9).The overall goal of any compensatory project shall be no net loss of wetland function and acreage and to strive for a net resource gain in wetlands over present conditions.The concept of"no net loss"means to create,restore, and/or enhance.a wetland so that there is no reduction to total wetland acreage and/or function. The City's Ordinance exempts Category 2 wetlands smaller than 2,200 ft2 and Category 3 wetlands smaller than 5,000 ft2 from regulation. 4.2 U. S. ArmyCorpsEngineers of En ineers Wetland Jurisdiction Placement of fill in wetlands within the City is also regulated by the COE and requires a permit under Section 404 of the Clean Water Act(CWA) .Currently,the COE regulates only those wetlands delineated under its 1987 Corps of Engineers Wetlands Delineation Manual (Department of the Army Environmental Laboratory,1987). The COE issues two types of wetland permits:individual and nationwide.Nationwide permits are prescriptive and apply to a limited set of activities that meet certain conditions. Recent changes to the nationwide permit program(U.S.Army,2000a)would apply to a qualifying project if unavoidable impacts to wetlands were proposed.Individual permits are required for activities that are not covered under the nationwide permit program. Depending on the specific details,Nationwide Permit 43(NWP 43,Stormwater Management Facilities)might apply to this stormwater system improvement project.The complete text for NWP 43 is attached in Appendix B.Basically,this nationwide permit applies to discharges of dredged or fill material for the construction and maintenance of stormwater management facilities,including activities for the excavation of stormwater ponds/facilities,detention basins,and retention basins;the installation and maintenance of SEA1E:11598671WETLANDS DELINEATION REPORITRENTON_WETLAND_INALDOC 7 WETLAND DEUNEATION AND CLASSIFICATION REPORT FOR THE NE 10TH STREET/ANACORTES AVENUE NE STORMWATER SYSTEM IMPROVEMENT PROJECT water control structures,outfall structures and emergency spillways;and the maintenance dredging of existing stormwater management ponds/facilities and detention and retention basins,provided the activity meets specific criteria(Appendix B). Due to a recent court ruling,the COE may no longer regulate isolated wetlands.The U.S. Supreme Court recently rejected the COE's claim to jurisdiction over isolated,intrastate waters(Solid Waste Agency of Northern Cook County vs.U.S.Army Corps of Engineers, January 9,2001).The court's opinion goes beyond the migratory bird issue and means that no intrastate,isolated water is subject to the provisions of Section 404(a) of the CWA (regardless of any interstate commerce connection). Projects requiring a federal permit decision(i.e.,both nationwide and individual 404 permits)also require compliance with the Endangered Species Act(ESA) (U.S.Army,2000a and I2000b).Projects that are considered"not likely to affect"or"likely to affect"threatened and/or endangered species will require a biological evaluation/biological assessment (BE/BA).The COE is experiencing significant delays reviewing projects for ESA compliance and consulting with other federal agencies(e.g.,National Marine Fisheries Service [NMFS] and/or USFWS).As a result,nationwide permits,which were once relatively simple to obtain,now must be submitted well in advance of construction(in many cases a year or more)due to ESA. 4.3 Washington State Department of Ecology Jurisdiction Section 404(b)permits also require a Section 401 Water Quality Certification from Ecology. An individual 401 certification is required for certain projects affecting wetlands. Ecology has the authority during the permitting process to review development plans,impacts to wetlands,and the proposed mitigation measures. 5.0 Site Conditions 5.1 Site History The history of the subject site is not known.The site is currently undeveloped;however,at one time the site was cleared and seeded with common pasture grasses.The site might have once been used as pasture.Minor earthwork was done to cut a short ditch,which might convey septic overflow or gray water from the residence located at the southeastern corner of the,site.Residential lots adjoin the site to the west.On several of these adjacent lots,fill has been placed,retaining walls constructed,and fences erected. 5.2 11 Soils The Soil Survey of King County Area, Washington(Snyder et al.,1973)reports Alderwood gravelly sandy loam as the dominant soil on the property.This soil type is not listed as a hydric soil(NRCS,1992).However,actual soil conditions on site varied from what was reported. Alderwood gravelly sandy loam,6 to 15 percent slopes (Map unit AgC). Alderwood soils are moderately well drained and have a weakly consolidated to strongly consolidated substratum at a depth of 24 to 40 SEA1E:11598671WETLANDS DELINEATION REPORTIRENTON_WETLAND_FINALDOC 8 WETLAND DEUNEATION AND CLASSIFICATION REPORT FOR THE NE 10TH STREET/ANACORTES AVENUE NE STORMWATER SYSTEM IMPROVEMENT PROJECT it '- inches.These soils typically occur on uplands.They formed under conifers,in glacial deposits.However,it is not unusual for inclusions of poorly drained(hydric)soils such as Norma,Bellingham,Seattle, Tukwila,and Shalcar to occur in areas mapped as Alderwood. Permeability of this soil is moderately rapid in the surface layer and subsoil,and very slow in the substratum.Roots penetrate easily to the consolidated substratum where they tend to mat on the surface.Water moves on top of the substratum in winter.Available water capacity is low.Runoff is slow to medium,and the hazard of erosion is moderate. The geotechnical investigation(CH2M HILL,2001)completed concurrently with this wetland investigation discovered dark brown,stiff/medium dense sandy silt to silty sand with scattered organics at the ground surface.Approximately 20 to 25 feet of glacial till underlay the 2-to 3-foot-thick surficial layer: 5.3 Hydrology The site is located in the Honey Creek subbasin,which drains to the May Creek watershed, and eventually to Lake Washington.Albeit limited,coho salmon are known to rear and spawn in approximately the lower one-half mile of Honey Creek(Foster Wheeler et al., 1995),which is approximately one mile downstream from the Vuong property. The site is located at the headwater of a small,unnamed tributary(0285A) that drains into the upper part of Honey Creek(Foster Wheeler et al.,1995).However,development has occurred north of the site and it appears that the northern part of tributary 0285A has been culverted and is no longer an open channel connecting to Honey Creek.In addition,a large portion of Honey Creek north of the project site was culverted in the last 30 to 40 years.Fish passage to the upper portion of Honey Creek might be difficult or impossible due to • impeldiments and blockages,beginning where Honey Creek runs under Union Avenue NE, approximately two-fifths mile northeast of the site. Water was not directly observed on the site during the delineation.However,indicators of hydrology were used to infer its presence or absence.Direct observation and measurement of surface water and shallow groundwater are more conclusive determinants of the presence and extent of wetland hydrology.To better understand the hydrology of the site, direct observation should occur in the early growing season(late February to early March). The geotechnical investigation(CH2M HILL,2001)summarizes the results of groundwater monitoring that was conducted from August 2000 to May 2001 using piezometers installed at thel site.The piezometers were installed in boreholes 30 feet deep(B-1)and 8 feet deep (B- 1A).Piezometer B-1 detected water only for the first reading in August 2000,at a depth of 29.0 feet below ground surface(bgs);water was not detected during any other readings. Readings at Piezometer B-1A recorded groundwater fluctuations from 4.0 feet to 12.8 feet bgs.These results indicate that water is perched in the upper till layer throughout much of the year,if not year round.However,it should be noted that this year has been one of the drier years on record;therefore,groundwater levels may have been lower than normal. • SEAT:1159 671WETLANDS DELINEATION REPORTIRENTON_WELAND RNALDOC 9 WETLAND DELINEATION AND CLASSIFICATION REPORT FOR THE NE 10TH STREET/ANACORTES AVENUE NE STORMWATER SYSTEM IMPROVEMENT PROJECT 5.4 Wetland Descriptions CH2M HILL identified one wetland on site and one off site,which are summarized in Table 4.The soils,vegetation,hydrology,rating category,and functions of these wetlands are described below.The approximate location of each wetland is depicted in Figure 3.The wetland acreage reported is calculated from the survey of the delineated boundaries. The wetlands delineated are palustrine,which describes "...all non-tidal wetlands darn inated by trees,shrubs,persistent emergent vegetation,emergent mosses,or lichens..."(Cowardin et al.,1979).Palustrine wetlands are further divided into dasses and subclasses based on characteristics of their substrate,dominant vegetation,and flooding regime. During the delineation,normal environmental conditions were present in the area,and the growing season was well advanced.

This wetland is not accessible to fish and does not provide habitat suitable for fish rearing or spawning. Soils.Snyder et al. (1973)identified the soils as Alderwood gravelly sandy loam,which is not listed as a hydric soil in King County(NRCS,2000).However,soils observed in Wetland B in the B horizon(12 to 14 inches bgs)were very dark brown(10YR 2/2)gravelly silty loam with dark yellowish brown mottles(10YR 3/6),which does not match the description for Alderlwood.See SP-02 in Appendix A. SEA E\1598671WETLANDS DEUNEATION REPORTIRENTON_WETLAND FINALDOC 10 WETLAND DELINEATION AND CLASSIFICATION REPORT FOR THE NE 10TH STREET/ANACORTES AVENUE NE STORMWATER SYSTEM IMPROVEMENT PROJECT Soils observed in the B horizon(10 to 14 inches bgs)in adjacent uplands were dark yellowish brown(10YR 4/4),which more closely matches the description for Alderwood. See SP-01 in Appendix A. Vegetation.Wetland B is dominated by palustrine emergent vegetation(PEM),with several isolated shrubs.Vegetation is dominated by slough sedge(Carex obnupta;OBL).Also occurring,but not dominant,were,soft rush(juncus effusus;FACW),daggerleaf rush(Juncus ens folius;FACW),small-flowered willowherb (Epilobium minutum;NL),bull thistle(Cirsium vulgare;FACU),red elderberry(Sambucus racemosa;FACU),colonial bentgrass(Agrostis tenu�is;FAC),and cut-leaf blackberry(Rubus laciniatus;FACU+). Adjacent uplands are dominated by cut-leaf blackberry and colonial bentgrass,with scattered red elderberry,bracken fem(Pteridium aquilinum;FACU),timothy(Phleum pratnse;FAC-),and velvet grass(Holcus lanatus;FAC). Hydrology.The sources of water to Wetland B are primarily precipitation and shallow seasonal groundwater from the adjacent drainage area.No streams or culverts flow into Wetland B,but a defined intermittent drainage flows from Wetland B(See Wetland C below).A ditch from the house to the east drains to Wetland B.This ditch is believed to be a septic overflow or gray water line. No sltanding water or soil saturation was observed during the field visit.The wetland appears to be seasonally flooded,but becomes dry in summer.Wetland B occurs in the headwaters of a small,unnamed creek that drains to Honey Creek and is identified in the May Creek Basin Lower Basin Conditions Map as stream 0285A(Foster Wheeler et al.,1995) (Figure 9).However,the northern part of the unnamed creek appears to have been culverted and is no longer an open channel.Also,a large portion of Honey Creek north of the site has been culverted. The presence of both wetland and upland plants in Wetland B indicates that water is present in the early growing season,but drains rapidly enough to allow upland plants an opportunity to establish and develop in the late spring,summer,and fall. Wetland Category.Applying the City's rating(Table 2),Wetland B is considered Category 3.The basis for this rating is that Wetland B is hydrologically isolated with low-diversity emergent vegetation that has been altered.Wetland B is less than 5,000 ft2.Category 3 wetlands less than 5,000 ft2 in size are exempt from the City's wetland regulations(RMC 4- 3-0501-B.7.a).A letter of exemption from the City would be required. A permit or exemption to build in Wetland B would be required from the COE.Permitting with the COE would depend on the nature of the wetland impacts associated with the proposed stormwater system improvement project.As discussed above(Section 4.2,U.S. Army Corps of Engineers Jurisdiction and Appendix B),Nationwide Permit 43 for stormwater management facilities would likely apply to this project.Mitigation might be required.However,due to the recent court ruling mentioned previously,it is also possible that the COE might not regulate this isolated wetland.

Wetland B provides some water storage,but this function is limited by its small size.Its small size and isolation also limit the hydrologic support function. 5.4.2 Wetland C General Description.Occurring off site to the north,Wetland C is a narrow,linear wetland associated with an intermittent drainage identified as stream 0285A(Figure 9) on the May Creek Basin Lower Basin Conditions Map (Foster Wheeler et al.,1995).However,there is no sigrficant channel development in this reach.This wetland is not likely accessible to fish and does not provide habitat suitable for fish rearing or spawning. The portion of this wetland occurring within 100 feet of the subject property has a surveyed size of approximately 1,033 ft2.The wetland extends northward but was not delineated beyond 100 feet of the subject property.Data was collected from a sample plot in Wetland C (Appendix A).This wetland was not identified on the NWI map(Figure 4),King County Wetland Inventory(Figure 5),Renton Wetlands Inventory Map (Figure 6),or the King County soil survey(Figure 7).However,the May Creek Basin Water Features Map(Foster Wheeler et al.,1995) identifies Wetland 50 north of the subject property,forming the headwaters of a small tributary(0285A) to Honey Creek(Figures 8 and 9). The following is an excerpt from the May Creek Current and Future Conditions Report describing the habitat of Wetland 50 (Foster Wheeler et a1.,1995): Current Conditions:This 2.6-acre Class-2 wetland inventoried by the City of Renton is the headwater to a very small tributary(0285A) to Honey Creek.The wetland is predominantly forested with deciduous trees, including aspen(Populus tremuloides).A small portion has been converted to lawn.The wetland provides moderate to high levels of groundwater discharge,floodflow alteration,and wildlife habitat.In spite of these important functions,this wetland has been severely disturbed by filling and buffer removal.Residences appear to have been built in the wetland on fill,with cultivated backyards ending at the current wetland boundary.Cat and dog intrusion is intense,and considerable trash dumping has occurred. Future Conditions:This wetland occupies an important landscape position and provides significant beneficial functions.Because it is surrounded by residential development,this wetland will continue to be subjected to the same intensive disturbances it currently experiences,and will decline from ongoing vegetation removal,trash dumping,and the • like.The wetland could benefit from a community clean-up and education effort. Soils.Snyder et al.(1973)identified the soils as Alderwood gravelly sandy loam,which is not listed as a hydric soil in King County(NRCS,2000).Soils in Wetland C were difficult to SEA1E11598671WETLANDS DELINEATION REPORTIRENTON WETLAND_FINALDOC 13 WETLAND DELINEATION AND CLASSIFICATION REPORT FOR THE NE 10TH STREET/ANACORTES AVENUE NE STORMWATER SYSTEM IMPROVEMENT PROJECT observe because of the dense gravel layer located near the surface.Soils were assumed to be hydric due to indicators of standing and flowing surface water. Vegetation.The wetland is dominated by palustrine forested vegetation(PFO).The generally native,undisturbed vegetation in Wetland C is dominated by an overstory of Oregon ash(Fraxinus latifolia;FACW),black cottonwood(Populus balsamifera;FAC),and red alder(Alnus rubra;FAC);the understory is dominated by seedlings and saplings,suggesting that the hydrologic regime is being maintained.Understory vegetation occurring,but not dominant,indudes soft rush,dustered rose(Rosa pisocarpa;FAC),Himalayan blackberry (Rubus discolor;FACU),English ivy(Hedera helix;NL),and creeping buttercup (Ranunculus repens;FACW). Hydrology.The sources of water to Wetland C are primarily precipitation and shallow seasonal groundwater from the adjacent drainage area.No streams flow into Wetland C. Altliough actual inundation or saturated soils were not observed,hydrologic indicators present include evidence of surface scour,standing water(bare soil with stained,matted leaves),beer cans and a baking pan,which likely were carried into the wetland and deposited by water.The wetland appears to be intermittently flooded,but becomes dry in summer.Wetland C forms the headwaters for an unnamed stream that drains to Honey Creek.However,the northern end of the unnamed stream appears to have been culverted. Also,a large portion of Honey Creek downstream of the project site has been culverted. Wetland Category.Applying the City's rating(Table 2),Wetland C is considered Category 2,requiring a 50-foot buffer(Table 3).The basis of this rating is that Wetland C is hydrologically connected and is located at the headwaters of an intermittent watercourse. Wetland C would be regulated by both the COE and the City;therefore,construction in the wetland or its buffer would require apermit or an exemption. • Wetland Functions.Wetland C provides moderate biological support due to its structural diversity;however,this support is limited by disturbance from the adjacent residential land uses.The combination of shallow gradient,occasional depressions,and vegetation in Wetland C likely helps maintain water quality.Wetland C provides some water storage in. the depressions,but this function is limited by its narrow configuration.The hydrologic support function is also limited by its small size and intermittent character. 6.0 Wetland Impact Avoidance Any unavoidable impacts to Wetlands B and C related to the proposed stormwater detention pond would be determined during the detailed engineering design and would be mitigated according to applicable regulations.The consequences of pond construction in this area could be drawdown of Wetland C or a change in flow to the wetland.Mitigation for or prevention of these consequences will be examined.

S. Corps of Engineers Nationwide Permit 43 (Adapted from U. S. Army Corps of Engineers, 2000a) 43. Stormwater Management Facilities. Discharges of dredged or fill material into nontidal waters of the United States,excluding nontidal wetlands adjacent to tidal waters, for the construction and maintenance of stormwater management facilities,including activities for the excavation of stormwater ponds/facilities,detention basins,and retention basks;the installation and maintenance of water control structures,outfall structures and emergency spillways;and the maintenance dredging of existing stormwater management ponds/facilities and detention and retention basins,provided the activity meets all of the following criteria: a. The discharge for the construction of new stormwater management facilities does not cause the loss of greater than one-half acre of nontidal waters of the United States, excluding nontidal wetlands adjacent to tidal waters; b. The discharge does not cause the loss of greater than 300 linear feet of stream bed; c. The discharge of dredged or fill material for the construction of new stormwater management facilities in perennial streams is not authorized; d. For discharges or excavation for the construction of new stormwater management facilities or for the maintenance of existing stormwater management facilities causing the loss of greater than one-tenth acre of nontidal waters,excluding nontidal wetlands adjacent to tidal waters,the permittee notifies the District Engineer in accordance with General Condition 13.In addition,the notification must include: (1) A maintenance plan.The maintenance plan should be in accordance with State and local requirements,if any such requirements exist; (2) For discharges in special aquatic sites,including wetlands and submerged aquatic vegetation,the notification must include a delineation of affected areas;and (3) A compensatory mitigation proposal that offsets the loss of waters of the United States.Maintenance in constructed areas will not require mitigation provided such maintenance is accomplished in designated maintenance areas and not within compensatory mitigation areas (i.e.,district engineers may designate nonmaintenance areas,normally at the downstream end of the stormwater management facility,in existing stormwater management facilities).(No mitigation will be required for activities which are exempt from Section 404 permit requirements); e. The permittee must avoid and minimize-discharges into waters of the United States at the project site to the maximum extent practicable,and the notification must include a written statement to the District Engineer detailing compliance with this condition(i.e., why the discharge must occur in waters of the United States and why additional minimization cannot be achieved); SEAIE11598671WERANDS DELINEATION REPORTIRENTON_WETLAND FINALDOC B-2 WETLAND DELINEATION AND CLASSIFICATION REPORT FOR THE NE 10TH STREET/ANACORTES AVENUE NE STORMWATER SYSTEM IMPROVEMENT PROJECT f. The stormwater management facility must comply with General Condition 21 and be designed using best management practices(BMPs)and watershed protection techniques.Examples may include forebays(deeper areas at the upstream end of the stormwater management facility that would be maintained through excavation), vegetated buffers,and siting considerations to minimize adverse effects to aquatic resources.Another example of a BMP would be bioengineering methods incorporated into the facility design to benefit water quality and minimize adverse effects to aquatic resources from storm flows,especially downstream of the facility,that provide,to the maximum extent practicable,for long term aquatic resource protection and enhancement; g. Maintenance excavation will be in accordance with an approved maintenance plan and will not exceed the original contours of the facility as approved and constructed;and h. The discharge is part of a single and complete project. (Section 404) Notification Requirement:Yes.Notification required for impacts greater than 1/10 th of an acre,work proposed in intermittent or ephemeral streams,and permanent above-grade fills above the headwaters and within the flood fringe of the 100-year floodplain.See Regional conditions below and National General Conditions 13—Notification and 26(b)(1)—Fills Within 100-Year Floodplains,for specific requirements. NOTE:Also review information in Migratory Bird section above(page 21). Regional Conditions 1. In addition to being restricted from use in tidal waters of the United States(defined in 33 CFR Part 328.4(b)),this NWP is not authorized for use in the nontidal waters of the United States listed below.An individual permit application must be submitted for any proposed work in these designated areas: a) Wetlands adjacent to lower perennial riverine systems(see Note below);or b) Coastal dunal wetland systems along the coast of Washington except for within the city of Long Beach provided the project is consistent with the approved"City of Long Beach Dune Management Report";or c) Lakes,playa lakes,prairie potholes,vernal pools,kettles,and camas prairie wetlands or within 100 feet of any such system;or d) In"Protected High-Functioning Wetlands"as identified in the Skagit WIN Phase III: Wetland Management Plan for the Port of Skagit County dated 1 August 1997. NOTE:Adjacent is as defined in 33 CFR Part 328.3(c).In the riverine systems,a line is drawn perpendicular to the river at the break between lower and upper perennial river systems. This NWP can be used in those wetlands upstream of this line only.These systems are - defined in the Appendix of the Public Notice. 2. The permittee must notify the District Engineer in accordance with the General Condition 13 for any proposed work located in intermittent or ephemeral streams.

EPA,State, Puyallup Tribe,and Chehalis Tribe 401 Certification-Denied without prejudice. An individual 401 Certification is required for all Section 404 activities. CZM Consistency Response-Denied without prejudice.An individual CZM Consistency Response must beobtained from the State for projects located in counties within the coastal zone.Consistency with CZM cannot be determined until any necessary consultation required under ESA is completed.The State's CZM review will start upon completion of ESA requirements.
