SEPA Checklist.pdf1
Purpose of Checklist:
The State Environmental Policy Act (SEPA), chapter 43.21C RCW, requires all govermnental 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 propose of this checklist is to provide information to help
you and the agency identify impacts from your proposal (and to reduce or avoid impacts fi•om the proposal, if it can be done) and to
help the agency decide whether an EIS is required.
Instructions forApplicants:
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 enviromnental 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.

The Talbot Road — Perrinville Creek Drainage Improvement Project is located between Talbot Road and BNSF railroad
tracks near the Puget Sound shoreline (Sheet 1). 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 runoff neighborhood 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 21 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.
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 project will occur on private properties at 8307 and 8229 Talbot Road, BNSF right-of-way and in the Talbot Road
public right of way in Edmonds, Washington.. (see enclosed drawings)
