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.

project and site. There are several questions later in this checklist that ask you to describe certain
aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may
modify this form to include additional specific information on project description.)
The project proposes a series of slope stabilization and residential structural stabilization
and repair actions along the subject property shoreline to restore the site following a
landslide that took place in late December of 2022. The landslide caused a portion of the
deck attached to the residence and the main shoreline bluff to destabilize and slide down the
slope into the existing bulkhead. Due to the force from the slide, the upland materials
pushed an approximately 20-foot linear section of bulkhead into the upper shore zone
(USZ).
Repair and stabilization of the residence will occur landward of the 50-foot shoreline buffer
and will consist of restoring the attached deck and implementing three retaining walls along
the top of slope. One retaining wall will tie into the existing concrete block wall along the
deck and the southeast extent (top) of the landslide area, and the second retaining wall will
run along the prior, preexisting top of slope area. The third wall will be located halfway up
the concrete stairs and will be in line with the start of the upper wall. The walls will be five
(5) to fifteen (15) feet in height and will be secured via soldier pile, with an additional 110
square foot triangular shotcrete wall utilized for additional site access stabilization in the
north. The retaining walls will be backfilled with suitable soil material the tops may be
planted to provide additional stabilization to help restore the top of slope. Overall, the
retaining walls will provide structural support beneath and immediately north of the
residence in the affected area.
Shoreline stabilization actions will consist of a mid-slope stabilization and a toe of slope
stabilization. The mid-slope stabilization will be provided between elevations 60 feet and 90
feet above mean sea level over an approximately 1,547-square-foot area located
perpendicular to the shoreline. The slope stabilization actions will occur landward of the 50-
foot shoreline buffer. The slope will be stabilized using a rockfall protection mesh with 50
mm opening and 3.8 mm wire securely drilled into the slope (Tecco Mat). The lower portion
of the affected slope area from the delineated OHW to approximately +20 feet NAVD88
consists of a gradual slope. This portion of the slope is fully within the 50-foot shoreline
buffer and will be enhanced with native trees and shrubs and reseeded to minimize erosion
and restore shoreline ecological functions. Additionally, the entire 50-foot shoreline setback
within the landslide area will be replanted with live willow stakes to further stabilize the
slope. The section of bulkhead displaced by the landslide will be restored to its preexisting
condition by lifting the existing riprap blocks and placing them in their original position
landward of OHW. The proposed bulkhead realignment will be performed during low tide
to minimize erosion potential, and access will be provided via a neighboring parcel or barge.
No impacts to existing eelgrass beds are proposed. All actions are the minimum necessary
to restore and stabilize the shoreline and associated residential structures.
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.

B. ENVIRONMENTAL ELEMENTS
1. Earth
a. General description of the site:
Flat Rolling Hilly Steep Slopes Mountainous
Other
b. What is the steepest slope on the site (approximate percent slope)?
Approximately 80 percent slope
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.
The NRCS soil survey map identifies two soil series on the subject property: Alderwood and
Kitsap soils, very steep (AkF), and Indianola loamy sand, 5 to 15 percent slopes (InC). Both
Alderwood and Kitsap soils, very steep and Indianola loamy sand, 5 to 15 percent slopes are
listed as non-hydric on the NRCS hydric soils list; however, Indianola loamy sand, 5 to 15
percent slopes is identified with up to 2 percent inclusions of hydric Norma soils (NRCS,
11/23).
d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe.
In relation to surface indications or history of unstable soils, the geotechnical report states: “the
subject slide event was triggered because of a broken water line that discharged water along the
slope surface. It should be noted that the slide was not the result of naturally occurring
processes, and to our understanding, no indications of slope instability had been noted before the
slide. This condition is generally corroborated through our review of local mapping resources,
lidar data, and aerial photographs of the area. The induced movement resulted in the creation of
a large washout feature and carried soil, deck and patio elements, and other debris down
gradient and was ultimately deposited at the base of the slope. The slide also displaced an
existing rockery that serves as a bulkhead at the shoreline. Based on our evaluations, the slide
initiated within the medium dense silty sand to poorly graded sand unit. It is unclear if, or to
what extent, the denser silty sand and sand and silt-dominated soils were mobilized during the
event. However, surficial exposures of these units can be seen along the exposed slope face,
particularly from the base of the slope. Since the event, it appears that no further mass soil
movement has occurred. Localized riling is apparent along the slope face and is likely attributed
to rainfall and the absence of vegetation along the slide scarp.” (Earth Solutions, 2023)
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.
Shoreline stabilization measures will be implemented along the face of the subject property
shoreline to stabilize the property following a landslide. Repair and stabilization of the residence
will include implementing three retaining walls along the top of slope. One retaining wall will tie
into the existing concrete block wall along the deck and the southeast extent (top) of the landslide
area, and the second retaining wall will run along the prior, preexisting top of slope area. The

third wall will be located halfway up the concrete stairs and will be in line with the start of the
upper wall. The walls will be five (5) to fifteen (15) feet in height and will be secured via soldier
pile, with an additional 110 square foot triangular shotcrete wall utilized for additional site
access stabilization in the north. The retaining walls will be backfilled with suitable clean upland
soil material from an approved site above the shotcrete. Bulkhead repair will involve restoring
the existing rockery bulkhead “in-kind” utilizing existing, salvageable materials that are present
in the area. The project intends to excavate the displaced rockery and reestablish the existing
keyway in general alignment with areas of the rockery that were undisturbed. See the site plan
for location of slope stabilization and associated fill material onsite.
f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe.
No clearing is proposed. The purpose of the project is to limit erosion through the introduction
of slope supporting objects such as soldier pile wall placement, anchored Tecco Mat placement,
upland of the 50-foot shoreline buffer and slope revegetation with native plants and bulkhead
repair in place using existing materials.
g. About what percent of the site will be covered with impervious surfaces after project construction
(for example, asphalt or buildings)?
No new impervious surfaces are proposed.
h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any:
Soldier pile wall placement, anchored Tecco Mat placement, and slope revegetation, see above.
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.
