SEPA ENVIRONMENTAL CHECKLIST
Purpose of Checklist
Governmental agencies use this checklist to help determine whether the environmental impacts of
your proposal are significant. This information is also helpful to determine if available avoidance,
minimization or compensatory mitigation measures will address the probable significant impacts or
if an environmental impact statement will be prepared to further analyze the proposal.
Instructions for Applicants
This environmental checklist asks you to describe some basic information about your proposal.
Please answer each question accurately and carefully, to the best of your knowledge. You may need
to consult with an agency specialist or private consultant for some questions. You may use “not
applicable” or "does not apply" only when you can explain why it does not apply and not when the
answer is unknown. You may also attach or incorporate by reference additional studies reports.
Complete and accurate answers to these questions often avoid delays with the SEPA process as well
as later in the decision-making process.
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.
Instructions for Lead Agencies
Please adjust the format of this template as needed. Additional information may be necessary to
evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse
impacts. The checklist is considered the first but not necessarily the only source of information
needed to make an adequate threshold determination. Once a threshold determination is made, the
lead agency is responsible for the completeness and accuracy of the checklist and other supporting
documents.
Use of Checklist for Nonproject Proposals
For nonproject proposals (such as ordinances, regulations, plans and programs), complete the
applicable parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS
(part D). Please completely answer all questions that apply and note that the words “project,”
“applicant,” and “property or site” should be read as “proposal,” “proponent,” and “affected
geographic area,” respectively. The lead agency may exclude (for non-projects) questions in Part B
- Environmental Elements –that do not contribute meaningfully to the analysis of the proposal.

description.)
The project is to subdivide the 19.86-acre property as a cluster subdivision of 20 single family
residential lots with a public road and tracts for open space, critical areas, and drainage
facilities. The project density is 1.0 du/ac, which is half of what the RS-15.0 zoning
designation allows.
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.
The subject property consists of one parcel situated in the Northeast ¼ of Section 12,
Township 21 North, Range 3 East, W.M. (King County Tax Parcel Number 1221039037).
The site is located just south of the intersection of 22nd Avenue SW and SW 309th Court.
B. ENVIRONMENTAL ELEMENTS
1. Earth
a. General description of the site:
(circle one): Flat, rolling , hilly, steep slopes , mountainous, other
b. What is the steepest slope on the site (approximate percent slope)?
The steepest slopes on the site exceed 40 percent in localized areas.
c. What general types of soils are found on the site (for example, clay, sand, gravel, peat,
muck)? If you know the classification of agricultural soils, specify them and note any
agricultural land of long-term commercial significance and whether the proposal results in
removing any of these soils.

Bulletin #050 – October 17, 2016 Page 5 of 16 k:\Handouts\Environmental Checklist
Soils on the site include Alderwood gravelly sandy loam and Alderwood Kitsap soils. The
land is not agricultural or of long-term commercial significance.
d. Are there surface indications or history of unstable soils in the immediate vicinity? If so,
describe.
As noted in the Geotechnical Engineering Report by GeoResources dated December 22,
2022 (Section 4.1): "Erosion was observed at the northern terminus of the ravine that
begins south of the end of 22nd Avenue SW. This erosion appears related to uncontrolled
discharging of stormwater runoff from the adjacent plat, significant yard waste dumping
into the ravine, and the past installation of the stormwater bypass line that extends south
along the west side of the ravine. The old culvert discharged above the ravine and based
on information obtained from the City, caused the erosion that created the ravine. Erosion
was observed on the east side of the ravine in the form of exposed soils. Uncontrolled
yard waste along the north side of the property has inhibited vegetation growth. Erosion
was observed along the margins of the ravine headwalls and a landslide deposit is
mapped in the eastern portion of the site.
"Since our original report was prepared, we understand that a landslide occurred about
700 feet north of the site on the slope that extends down from the top of the glacial upland
area to SW Dash Point Road (SR 509). The landslide occurred on March 16, 2017. The
City hired Landau Associates to do an initial review of the slide. In their July 6, 2017,
Technical Memorandum to the City, they concluded that the rise of the “true” groundwater
table within the deeper advanced outwash caused the shallow colluvium to fail, along with
surface water from the ditch along SW 308th Street and above the failure. The
topography, surface water runoff, and soil conditions differ in this area from the main
Creekwood Plat property, and the area of the slide should have no impact on the
proposed project."
e. Describe the purpose, type, total area, and approximate quantities and total affected area of
any filling, excavation, and grading proposed. Indicate source of fill.
Minor cuts and fills will occur for site development of lots and the new road. New Road A,
which crosses the ravine in the north-central portion of the site, will be constructed with
an earth fill (using on-site soils) embankment supported by cast-in-place retaining wall.
Approximately 37,000 cubic yards of grading will occur as balanced cut and fill with one
consolidated site development activity for the clearing and grading of the new road and
pad graded of lots. Of that grading, approximately 10,000 cubic yards will be topsoil
strippings that will be placed back onto open spaces within the site, excess topsoil will be
exported to an approved location. If needed, structural fill would come from an approved
source. If needed, structural fill will come from an approved source.
f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe.
During construction erosion could occur as a result of precipitation events. During dry
weather dust may also be generated during the earthwork phase.
g. About what percent of the site will be covered with impervious surfaces after project
construction (for example, asphalt or buildings)?
Approximately 19 percent of the site will be covered by impervious surfaces, including
Road A improvements along with future homes and driveways.
h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any:

www.cityoffederalway.com
Bulletin #050 – October 17, 2016 Page 6 of 16 k:\Handouts\Environmental Checklist
A TESC Plan and SWPPP will be prepared, and the contractor will need to install erosion
control best management practices and maintain them throughout construction. Dust will
be controlled by using a water truck as needed during the dry season. Completing
construction of the roads and pad-graded lots will facilitate control of erosion and other
construction impacts to one singular construction season.
2. Air
a. What types of emissions to the air would result from the proposal during construction,
operation, and maintenance when the project is completed? If any, generally describe and
give approximate quantities if known.
During construction, air emissions may include exhaust from construction equipment.
After construction, air emissions may include vehicle exhaust, cooking smells, and wood-
burning stove smoke typical of residential suburban development.
b. Are there any off-site sources of emissions or odor that may affect your proposal? If so,
generally describe.
Offsite sources of emissions include vehicle exhaust from nearby roads.
c. Proposed measures to reduce or control emissions or other impacts to air, if any:
No measures to reduce or control emissions are warranted or provided.
3. Water
a. Surface Water:
1) Is there any surface water body on or in the immediate vicinity of the site (including year-
round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and
provide names. If appropriate, state what stream or river it flows into.
Yes, the site contains several streams and wetlands that contribute to Lakota Creek which
flows to Puget Sound. As documented in their Wetland Report, Soundview Consultants
“confirmed the presence and boundaries of the following potentially regulated critical
areas onsite: three wetlands (Wetlands B, D, and E/F), three drainages (Drainages W, X,
and Y), and one stream (Stream Z). In addition, one non-regulated seep (Seep C) was
identified on the subject property, and two wetlands (Wetlands A and G) were identified
offsite within 225 feet of the subject property. No other potentially regulated wetlands,
waterbodies, or other fish and wildlife habitat were identified within 225 feet of the subject
property during the site investigations”.
2) Will the project require any work over, in, or adjacent to (within 200 feet) the described
waters? If yes, please describe and attach available plans.
Yes, the project will work within 200 feet of on-site surface waters and wetlands. As
documented in their Wetland Report, Soundview Consultants: “The Applicant proposes
residential development of the subject property with a 20-lot residential plat and associated
infrastructure including internal site access and parking, utilities, and stormwater
infrastructure. The proposed project has been carefully designed to avoid impacts to the
identified critical areas and associated buffers to the greatest extent feasible, and direct
impacts, in-water work, and impacts to the buffers of Wetlands A, B, D, E/F, and G,
Drainages W and X, and Stream Z are avoided entirely. However, due to the need to

Bulletin #050 – October 17, 2016 Page 7 of 16 k:\Handouts\Environmental Checklist
provide site access in compliance with the City of Federal Way’s street design standards,
steep slopes which limit the developable areas onsite, the need to maintain site drainage
patterns, and the location of Drainage Y near the northern boundary of the subject property,
complete avoidance is not feasible. The proposed project requires necessary unavoidable
impacts to 6,115 square feet of the buffer of Drainage Y to provide an access road across
the northern boundary of the subject property that complies with the City of Federal Way’s
street design standards and to provide a stormwater connection that maintains existing site
drainage patterns following development of the subject property.
The proposed work will result In approximately 148 square feet of permanent intrusion to
the Drainage Y buffer due to the construction of a sidewalk and associated retaining wall.
Temporary impacts into this buffer will extend beyond the permanent intrusion due to
placement of fill and other grading activities associated with the road construction.
3) Estimate the amount of fill and dredge material that would be placed in or removed from
surface water or wetlands and indicate the area of the site that would be affected. Indicate the
source of fill material.
No fill or dredging is proposed in surface waters.
4) Will the proposal require surface water withdrawals or diversions? Give general description,
purpose, and approximate quantities if known.
No surface water withdrawals or diversions are proposed.
5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan.
The site is not located within a 100-year floodplain.
6) Does the proposal involve any discharges of waste materials to surface waters? If so,
describe the type of waste and anticipated volume of discharge.
The project is served by sanitary sewer service from Lakehaven Utility District which will
convey all wastewater safely offsite in an underground sewer collection system.
Stormwater runoff will be collected onsite in a closed pipe system and conveyed to an
onsite storm detention vault and water quality system. The outfall from this system will
connect to an existing 24-inch drainage pipe and catch basin system that discharges to
Drainage Z on site. No new discharge location is proposed. The volume of stormwater
discharge will be controlled to mimic existing flows as required by the 2021 KCSWDM.
b. Ground Water:
1) Will groundwater be withdrawn from a well for drinking water or other purposes? If so,
give a general description of the well, proposed uses and approximate quantities withdrawn
from the well. Will water be discharged to groundwater? Give general description, purpose,
and approximate quantities if known.
No groundwater will be withdrawn for any purpose.
2) Describe waste material that will be discharged into the ground from septic tanks or other
sources, if any (for example: domestic sewage; industrial, containing the following
chemicals. . .; agricultural; etc.). Describe the general size of the system, the number of such
systems, the number of houses to be served (if applicable), or the number of animals or
humans the system(s) are expected to serve.

Bulletin #050 – October 17, 2016 Page 8 of 16 k:\Handouts\Environmental Checklist
The site is served by a public sanitary sewer system so there will not be any onsite
sewage disposal systems; therefore, no waste materials will be discharged to ground or
surface waters.
c. Water runoff (including stormwater):
1) Describe the source of runoff (including storm water) and method of collection and disposal,
if any (include quantities, if known). Where will this water flow? Will this water flow into
other waters? If so, describe.
Runoff from the project will occur from precipitation falling on cleared and uncleared
surfaces. Stormwater generated by the development will be collected, controlled and
routed to an on-site detention vault and water quality facility located in Tract B before
being discharged to an existing stormwater pipe in Tract C. Site drainage currently and
will continue to flow to Lakota Creek and Puget Sound.
2) Could waste materials enter ground or surface waters? If so, generally describe.
The water quality facility and erosion control measures as well as the sanitary sewer
system will limit the risk of waste materials entering ground or surface waters through
project generated stormwater.
3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so,
describe.
The proposal does not impact or affect drainage patterns in the vicinity of the site.
d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage
pattern impacts, if any:
All project-generated stormwater will be collected and conveyed to the on-site detention
and water quality treatment facilities as noted above. Release of stormwater will be
metered to mimic existing flows.
