SEPA Checklist.pdfPurpose 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 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.
NOTE: Projects generating new traffic will be required to submit a Traffic Study prepared by a licensed Professional
Civil Engineer. Specific requirements for the Traffic Study may vary depending upon the project, and will be provided
by the City Engineer upon request. Please contact the Engineering Division at 425-771-0220 for specific study
requirements. City review of the Traffic Study may require assessment of the "Development Project Peer Review" fee
of $45 plus the cost of the review.
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 "proposer," and "affected geographic area," respectively.

aspects of your proposal. You do not need to repeat those answers on this page.
The original SEPA checklist from May 2010 desired the project as follows:
"The project involves work in Perrinville Creek, modifications to an existing high-flow bypass
structure, and relocating a storm drain and outfall to Perrinville Creek. The storm drain receives
runoffneighborhood streets and an unnamed stream that drains from Southwest County Park.
The project will remove sediment that has accumulated in the lower portion of Perrinville Creek,
improve fish passage, replace an existing storm drain with a larger pipe, and provide channel
improvements to improve fish habitat and resolve flooding of private property. The project will occur
on private properties at 8307, 8311, and 8229 Talbot Road, BNSF right-of-way and in the Talbot
Road public right of way in Edmonds, Washington.
This project will occur in two phases. Phase 1, to be completed in 2010, will address the
sedimentation and aggradation to alleviate the short-term flooding risk during the winter of 2010-
2011. Phase 2, to be completed in 2011, will address the inadequate storm drain on 8307 Talbot Road
by installation of a larger pipe. Phase 2 will also include channel improvements to improve fish
passage and fish habitat. "

Phase I of the project was completed in 2010 (removal of sediment and other material upstream of the
diversion structures and installation of a new weir plate just downstream of the diversion structures). There
has been two major changes to Phase II of the project since the May 2010 SEPA checklist. 1)The routing
of the stormwater pipe has changed (See Figure 1 and the enclosed draft plan set), and 2) The mitigation
for the project approved by WDFW will now take place in a second location, upstream of the storm
drainage improvements, rather between the BNSF tracks and Talbot Rd (See Critical Areas Report —
Perrinville Creek Mitigation & Enhancement Plan, The Watershed Company, November 1, 2011).
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 range or boundaries of the site(s).
Provide 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.
The storm drainage improvement project will occur within the City's easement at 8229 Talbot Road and in
the Talbot Road public right of way in Edmonds, Washington. The upstream migration will occur on
private property at 18028 76th Ave W (see enclosed drawings).
