Checklist_Storm Facility Retrofit StudyDEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT 1 ENV ENVIRONMENTAL CHECKLIST Planning Division 1055 South Grady Way-Renton, WA 98057 Phone: 425-430-7200 | www.rentonwa.gov PURPOSE OF CHECKLIST: The State Environmental Policy Act (SEPA), Chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write “do n ot 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 wh ich 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. 2 H:\File Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-4129 Stormwater Facility Retrofit Study\1300 SEPAEnv.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. The city of Renton owns and maintains over 400 stormwater facilities constructed as far back as the 1970s to mitigate for the stormwater impacts of urbanization. Between the 1970s and early 1990s, stormwater facilities were primarily focused on providing stormwater storage (i.e., detention). Since the 1990s, design standards have advanced so that today’s stormwater facilities provide better water quality treatment to mitigate the detrimental impacts of stormwater pollutants on stream water quality and aquatic habitat. These newer stormwater treatment systems target the removal of suspended solids, dissolved heavy metals, nutrients, and petroleum hydrocarbons. The city received a grant from the Washington State Department of Ecology (DOE) to perform a study of many of the existing flow control facilities that have little or no water quality treatment features. The overarching goal is to improve the water quality in multiple creeks within the city that are part of the Cedar River/Lake Washington and Duwamish/Green watersheds. The study entailed a series of six sequential analytical tasks undertaken to prioritize the sites with the greatest potential to improve water quality. 1. Existing Facility Selection: Selecting existing 49 flow control facilities for further assessment. 2. Existing Condition Summary: Collecting and summarizing existing flow control facility information 3. Treatment Gap Analysis: Identifying deficiencies in the treatment of existing flow control facilities. 4. Retrofit Type and Opportunity Identification: Determining type of opportunities available and feasibility of retrofitting. 5. Retrofit Opportunity Scoring and Prioritization: Developing a method to screen retrofit opportunities with a ranked list. 6. Conceptual Design of highest Priority Sites: Developing project conceptual designs and cost estimates for the top three prioritized retrofit sites. Following the completion of this these tasks, the top three facilities prioritized for water quality retrofits are: A. Kelsey Lane. The site is near the intersection of 108th Ave SE and SE 173rd Street. The existing area on west side 108th Ave SE will be turned into a compost amended bioswale 4 H:\File Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-4129 Stormwater Facility Retrofit Study\1300 SEPAEnv.

The site is near the intersection of SE 170th Street and SE 169th Place. The existing bioswale at the corner of this intersection will be converted to a bioretention facility to increase treatment capacity to partially meet current water quality treatment standards and requirements. C. South Knoll. The site is near the intersection of Oakesdale Ave SW and SW 3rd Place. A media filter vault with Modular Wetland System – Linear (LMW) will be installed near the intersection to fully meet current water quality treatment standards and requirements. 12.
