The project will result in the creation of a new left turn lane to accompany an existing left turn lane. A sidewalk will also be constructed on the east side of West Valley Highway as part of this project. As this project is to expand an existing right-of-way, a SEPA checklist would not be required. However, the project falls within 200 feet of the Ordinary High Water Mark (OHWM) of the Green River, requiring a Substantial Shoreline Development Permit. Agencies with jurisdiction: None Summary of Primary Impacts: • Earth The steepest slope in the project area is approximately 2%. The soils are primarily silt and fine sand with no history of instability. Approximately 1,000 cubic yards of gravel base materials will be required for establishing new road surface. Silt fencing will be used where appropriate. • Air Exhaust from vehicles and dust may occur during construction. 6300 Southcenter Boulevard, Suite #100 0 Tukwila, Washington 98188 0 (206) 431-3670 0 Fax (206) 41313665 E98-0014 SEPA Checklist - City of Tukwila Public Works West Valley Highway road improvements February 16, 1999 • • • Water The western portion of the project is approximately 70 feet from the Green River OHWM. Approximately 250 square yards of sidewalk will be developed along the east side of West Valley Highway. The Green River lies on the west side of West Valley Highway. No discharge of waste will occur into stream. The project includes adding catch basins and pipes to collect runoff from ponding areas on impervious surface, which will be routed to an exiting collection system that is discharged to the Green River. The proposed catchbasin system appears to be less than the 5,000 square foot threshold for requiring water quality features, per the City of Tukwila Storm Water Ordinance, Tukwila Municipal Code (TMC) 14.30.080(8). Siltation control measures will be used during construction. • Plants A grass strip will be removed for street widening. The area will be seeded following construction. • Animals No known threatened species or migration routes nearby. • Energy/Natural Resources Electricity, Gasoline or other fuels may be used for machinery during construction. • Environmental Health Some short term noise will be generated during construction time period, lasting between 7:00 a.m. and 10:00 p.m. • Land/Shoreline Use The project will occur in the right-of-way, but surrounding properties are zoned Tukwila Urban Center and Commercial/Light Industrial. No structures will be demolished. • Housing No housing is proposed nor will development reduce housing. • Aesthetics No structures are proposed. E98-0014 SEPA Checklist - City of Tukwila Public Works West Valley Highway road improvements February 16, 1999 • • • Light and Glare No impacts. • Recreation The adjacent Interurban Trail and Green River Trails will not be impacted by the project. • Historic/Cultural Preservation No known places or landmarks. • Transportation The project will expand the right-of-way by the creation of an additional turning lane and a sidewalk. The site is served by public transportation. No new parking will be required nor will new streets or improvements to roads be created. • Public Services Proposed development will not impact or require specific public services. • Utilities The existing storm drainage system, owned and operated by the City of Tukwila, will be modified for this project. Recommendations: DNS From: Robin Tischmak To: Phil Fraser Date: 1/26/99 11:13am Subject: Re: SEPA/Shoreline for West Valley Highway Michael - From our calculations, we have determined that we are adding less than 5,000 sf of new impervious surface with this project. When you take into consideration that we are constructing part of the widening for the street and sidewalk on top of existing impervious paved and gravel shoulder, the actual new impervious surface is less than 5,000 s.f. My understanding is that this threshold and above requires water quality treatment. Therefore we are not required to provide any additional water quality treatment with this project. Let me know if you have additional information that we should discuss regarding this matter. Robin »> Michael Jenkins 01/25/99 02:28PM »> Robin, I determined the applicaton to be complete and sent it out for public notice. The last date to comment in Feb 16. When I reviewed the checklist again I noticed that the strom drainage system would modified for additional catch basins and that this would continue to outfall directly into the Green River. What plans have been made to provide treatment at the new catch basins prior to entering into the existing system. mj CC: Michael Jenkins • City of l u la John W.

What will make the application complete is a submittal that includes the following information: • A site plan drawn to 1"=20' or 1"=30' scale clearly showing the area of construction and the proposed improvements. • A survey over the entire construction area at the same scale as the site plan • Shoreline profile cross-sections over the construction area, at 75 foot intervals I have included a copy of recent Shoreline Permit submittals as an example of complete applications that have been accepted by the Department of Ecology. While the construction drawings that you provided give a good picture of the proposal, they are not of the quality that the Department of Ecology would accept. Due to the public comment requirement, the technical level presented in the 50% construction drawings may be difficult for the general public. I hope you find the examples helpful when preparing new conceptual plans for SEPA and Shoreline review.

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, 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. 96006 \ Reports \ Sepa (10/31/97) \jc 1 • • A.

SUPPLEMENTAL SHEET FOR ALL PROJECT AND NON -PROJECT PROPOSALS The objectives and the alternative means of reaching the objectives for a proposal will be helpful in reviewing the foregoing items of the Environmental Checklist. This information provides a general overall perspective of the proposed action in the context of the environmental information provided and the submitted plans, documents, supportive information, studies, etc. 1. What are the objective(s) of the proposal? The proposal objective is to provide adequate left turn storage from northbound West Valley Hwy. to westbound Strander Blvd. The existing left turn lane does not have adequate storage for the number of left turns and vehicles back up into the through lanes causing safety problems and delays. 2. What are thealternative means of accomplishing these objectives? Lengthening the single existing left turn lane to meet storage requirements is the other alternative. 3. Please compare the alternative means and indicate the preferred course of action: Lengthening the existing single left turn lane would require widening of West Valley Hwy. further south than dual left turn lanes.

It also can be constructed without causing severe impacts to abutting properties or the Green River. 4. Does the proposal conflict with policies of the Tukwila Comprehensive Land Use Policy Plan?
