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.

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

(CABS) to fully meet current water quality treatment standards and requirements.
B. Benson Glen. 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. 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
required to duplicate maps or detailed plans submitted with any permit applications related to
this checklist.

D. SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS [help]
(IT IS NOT NECESSARY to use these sheets for project actions.)
Because these questions are very general, it may be helpful to read them in
conjunction with the list of the elements of the environment.
When answering these questions, be aware of the extent the proposal or the types of
activities likely to result from the proposal, would affect the item at a greater intensity or at a
faster rate than if the proposal were not implemented. Respond briefly and in general terms
1. How would the proposal be likely to increase discharge to water; emissions to air;
production, storage, or release of toxic or hazardous substances; or production of noise?
The City of Renton Stormwater Facility Retrofit Study will not increase discharge to
water; emissions to air; production, storage, or release of toxic or hazardous substances;
or production of noise. Future water quality retrofits assessed and prioritized do not
inherently increase discharges.
Proposed measures to avoid or reduce such increases are:
No measures are proposed because the City of Renton Stormwater Facility Retrofit Study
will not increase discharge to water; emissions to air; production, storage, or release of
toxic or hazardous substances; or production of noise.
2. How would the proposal be likely to affect plants, animals, fish, or marine life?
The City of Renton Stormwater Facility Retrofit Study prioritizes water quality retrofits
at multiple flow control facilities. When prioritized projects are delivered, they will
result in improved water quality from the discharges of these facilities, which will
positively affect animals, fish, or marine life in the receiving waters.
Proposed measures to protect or conserve plants, animals, fish, or marine life are:
No measures are proposed to protect or conserve plants, animals, fish, or marine life
because the City of Renton Stormwater Facility Retrofit Study will positively affect
