NOTICE OF DECISION — SEPA PLANNED ACTION ADDENDUM
To: Brian Ellingson, Applicant for Sabey Corporation
State Department of Ecology, SEPA Division
FILE NUMBER: E2000 -021 Planned Action
LOCATION: 3355 S. 120th Place, International Gateway East
LEAD AGENCY: City of Tukwila
Description of Original Proposal:
The previous application to construct a new 89 space parking lot for Exodus Communications
was designated as a planned action pursuant to TMC 21.04.156 in December of 2000. Included
in the scope was construction of an underground stormwater detention system, site lighting,
stairs, ramps and retaining walls. The plan required 3,200 cubic yards of cut and associated
structural fill.
Description of Addendum:
The original lot has not been constructed and revised plans have been submitted to the City of
Tukwila. The current plan involves regrading of a vacant site to construct a 74 space parking lot.
Included in the scope is construction of an open stormwater detention pond, site lighting, stairs
and landscaping. The plan requires 2,100 cubic yards of cut and 350 cubic yards of fill.
The City has determined that the addendum does not have a probable significant adverse impact
on the environment. An environmental impact statement (EIS) is not required under RCW
43.21c.030 (2) (c). This decision was made after review of the project scope and other
information on file with the lead agency. This information is available to the public on request.
The original decision was issued December 15, 2000. This addendum is adopted on October 17,
2003.

ENVIRONMENTAL CHECKLIST
Purpose of Checklist:
The state Environmental Policy Act (SEPA), Chapter 43.21C RCW, requires all govemmental agencies to
consider the environmental impacts of a proposal before making decisions. An environmental impact statement
(EIS) must be prepared for all proposals with probably 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.
Instruction for Applicants:
. This environmental checklist asks you to describe some basic information about your proposal. The City uses 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 City staff 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. Attached any additional information that will help describe your proposal or its
environmental effects. The City may ask you to explain your answers or provide additional information
reasonably related to determining if there may be significant adverse impact.
Use of checklist for nonproject proposals:
Nonproject proposals refer to actions which are different or broader than a single site specific development
project, such as plans, policies and programs.
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 read "proposal ", "proposer", and "affected geographic area ", respectively.

Pacific Highway South
Tukwila, Washington
Dear Doug:
•
In accordance with your request, ECI. observed a series of test pit excavations along the
proposed roadway and trailer staging areas of the site. The purpose of our services for this
phase of the project was to observe soil conditions and the existing sloping areas of the site,
and provide recommendations for grading of the site.
Project Description
Construction- of two office buildings is proposed for the site located on the east side of
Highway 99, east of the existing Intergate West development. Preliminary grading of the site
will involve the construction of several temporary access roads, and a staging area for office
trailers. The roadways and office trailer area will be used during the construction of the
proposed office buildings, and during the renovations to the existing Intergate East buildings.
A combination of cut and fills will be necessary to complete the proposed grading.
Subsurface Conditions
Six test pits were excavated in the vicinity of the planned roadways and staging area on May
15, 2000. Silty sand with gravel fill underlain by medium dense to very dense silty sand and
silt soils was observed at the majority of the test pit locations. The approximate location of
the test pits are provided on the attached site plan (Plate 1 and 2). The following is a
description of the soil conditions observed.

Conclusions
Based on the soil conditions observed at the test pit locations, the planned grading for the
roadway areas is feasible. Due to the moisture sensitive nature of the existing fill and
underlying native soils, the grading activities should be performed during dry weather
conditions. Measures to control drainage and reduce erosion of the graded surfaces and
existing slopes should be implemented. ECI should periodically observe_the grading for the
temporary roadways.
In the vicinity of the proposed office trailer staging area, existing fills of up to five feet in depth
are present (TP -2). Due to the loose and saturated condition of the existing fill,
overexcavation and the use of rock or recycled concrete may be necessary below the trailer
supports. In our opinion, the trailers should maintain a minimum setback of twenty (20) feet
from the top of the existing rockery located to the east of the proposed trailer staging area.
During our site visit to observe the test pit excavations, the existing slopes at the site were
observed for signs of instability. No signs of slope instability were observed at the time of our
site visit. We understand the proposed grading operations will not involve any deep cuts into
the existing steep slope areas of the site. The placement of fill is planned along the toe of
slopes and below the existing rockery at the lower southeast corner of the site. In our
opinion, the proposed placement of fill and initial grading of the site will help improve site
drainage, and the overall stability of the site.
ECI should periodically observe the grading operations and test the compaction of fills, as
necessary, during the grading operations.
