This letter serves a notice of decision that application number E08 -011 is designated as a Planned •
Action and is issued pursuant to TMC 21.04.156.
PROJECT BACKGROUND
FILE NUMBER: E08 -011, SEPA Planned Action
APPLICANT: The Boeing Company
REQUEST: Approval for designation of a Planned Action for site work on a 4.6 -acre area of a
larger, 9.8 acre site, known as the Boeing Isaacson parcel. Proposed work includes
demolition of asphalt and concrete, excavation and disposal of a mound of soil,
installation of stormwater collection and treatment systems, and repaving.
LOCATION: 8811 East Marginal Way South
PROJECT DESCRIPTION: The project proposal is to remove an asphalt -paved mound of soil.
Proposed construction activities associated with the underlying Public Works Type C Grading
permit will include demolition of portions of the existing asphalt and concrete pavement,
excavation of soil for off -site disposal, grading, installation of a stormwater collection and
treatment system, and repaving the disturbed area. Soil to be removed was previously determined
to contain hazardous levels of arsenic, which was stabilized in 1991 to prevent leaching of
arsenic. Soil samples and analysis in January 2008 determined that the soil now contains arsenic
at a level less than 5 milligrams per liter, an amount which is no longer characterized as
hazardous and allows disposal of the soil as solid waste. The parcel on which the proposed work
will occur is approximately 9.8 acres in size, and the proposed work is on a 4.6 acre area of the

as a SEPA Planned Action.
I. BACKGROUND/PROPOSAL
Tukwila's Manufacturing and Industrial Center (MIC) is one of the Puget Sound region's
major industrial centers. Industrial development over most of the sub -area was evaluated in
multi -site environmental review. In 1992, a programmatic environmental impact statement
(EIS) was prepared for the Duwamish Corridor master plan, a proposal to redevelop Boeing
properties in the MIC over a 10 year period. In 1998, sub -area plan/EIS updates extended the
previous analysis of the corridor's Boeing properties (about 650 acres) to the entire MIC sub-
area (about 1,370 acres). As part of this Planned Action review for the current proposal, the
impacts of the current proposal are compared to 1998 Integrated GMA Implementation Plan
and Final Environmental Impact Statement to ensure that all impacts have been mitigated.
One Planned Action determination has been issued previously for the site, on September 11,
2000, for construction of a 212,000 square foot building with 150 parking stalls and other
site improvements including landscaping. The site is currently vacant. Please refer to file
number E2000 -018 for more information on the previously- issued SEPA Planned Action.
The current proposal is to grade an approximately 4 rt 6 acre area consisting of a mound of
soil that has been paved over with asphalt and concrete, to reduce the mound effect thereby
bringing the site to a more consistent grade. Existing asphalt and concrete will be demolished
as part of the underlying Public Works permit, and the area will be repaved with asphalt after
the soil is excavated and disposed of off -site and a stormwater collection and treatment
system is installed. The work area for this project is zoned Manufacturing Industrial
Center/Heavy (MIC/H). Though the western portion of this parcel is located within the 200 -
foot regulated buffer of the Duwamish River, no portion of the work will be located within
the 200 -foot buffer.
Materials to be excavated include soil previously determined through the toxicity
characteristic leaching procedure (TCLP) to contain elevated levels of arsenic, in
concentrations in excess of 5 milligrams per liter (mg/L). According to a Technical
Memorandum from 2001 by staff in the Environmental Resources Management division of
the Boeing Company, the soil did not exhibit any other hazardous waste characteristics and
did not contain any listed waste. The contaminated soil was treated in 1991 using a
stabilization process to reduce the leachability of the arsenic. In January 2008, Landau
Associates conducted sampling and analysis of the treated soil and confirmed that TCLP
concentrations of arsenic were below 5mg/L. At this concentration, the stabilized soil is no
longer designated as hazardous waste and can be disposed of as solid waste.

Currently, stormwater on the site is discharged to the Duwamish River via an outfall
located south of the project parcel. No change in the volume or peak flows of stormwater
is anticipated with this project. Installation of two new Vortech's stormwater
collection/treatment systems and new piping where there are grades exceeding 0.5 percent
is proposed with this project, as part of the underlying Public Works permit. Installation
of these new facilities is being done to meet requirements for water quality treatment for
the project area.
II. DECISION CRITERIA
This proposal was identified as a potential Planned Action because of its location within the
subarea subject to the Tukwila Manufacturing /Industrial Center Integrated GMA
Implementation Plan and Environmental Impact Statement. The determination of whether a
project fits the Planned Action criteria is divided into two phases. Each phase is described
below, including a response that explains how the current proposal meets the criteria.
1) In the first phase, a determination is made whether the project satisfies all of
the following characteristics (contained in TMC 21.04.152 Planned Actions
Identified):
1. The action is a `permitted use" located within the MIC /L (TMC
18.36.020) and MIC /H (TMC 18.38.020) zones and/or is an accessory use
(TMC 18.36.030 and 18.38.030 respectively).
2. The action is:
a. not an "essential public facility" as defined in RCW 36.70.200 and
TMC 18.06.270,
b. not a conditional or unclassified use, in the respective MIC /L or
MIC /H zones,
c. not a development, any portion of which includes shoreline
modifications waterward of the ordinary high water mark,
d. not a development associated with 16th Avenue Bridge construction
activities.
Response: The proposal for this site is to conduct grading and excavation,
removing a mound of soil capped with asphalt and concrete pavement and installing
water quality facilities. The 4.6 -acre area disturbed with this permit will be repaved
with asphalt once the soil mound is removed and the water quality facilities are
installed. The site is currently vacant, and there is no other use anticipated for the
site at this time. The site's status /use as a vacant lot is a permitted use within the
JR Page 3 of 5 09/122008 1254 PM
H:\Planned Action SEPA\Boeing- Isaacson Mound Removal\E08 -011_Boeing Mound Removal_SR.doc
MIC /H zoning district, and is not an essential public facility or a development
associated with 16th Ave Bridge construction activities. The project does not involve
work waterward of or within the 200 -foot buffer from the ordinary high water mark
of the Duwamish River.
2) Once the project has met the initial test to qualify as a planned action, it must then
show the following:
A. Will all of the impacts of the proposal be mitigated by the time the project is
complete? Please document all mitigation measures, using attachments if
necessary.
Response: Based on the answers provided in the Endangered Species Act (ESA)
Screening Checklist, the project does not constitute a "take" under ESA. The
following provides clarification for items answered "yes" in the ESA Screening
Checklist. Compliance with existing codes will mitigate any impacts related to
grading, stormwater, and hazardous substances.
(1) Grading and clearing —The project includes demolition of existing asphalt
and concrete, excavation of soil, and installation of stormwater quality
infrastructure. The site currently has no vegetation; there is no clearing or
disturbance of vegetation involved with the proposed construction
activities. The applicant has prepared a Technical Information Report that
outlines measures that will be taken to prevent erosion during construction
activities, as well as a Stormwater Pollution Prevention Plan (SWPPP).
Additionally, the applicant is in the process of applying for a Construction
Stormwater General Permit from the Washington State Department of
Ecology. As stated in the SWPPP, the applicant will follow best
management practices to prevent erosion and sedimentation, and to
identify, reduce, eliminate or prevent stormwater contamination and water
pollution from construction activity.
(2) Processing or handling, storage, or treatment of hazardous substances —
Applicant shall be responsible for obtaining any applicable permits from
the Puget Sound Clean Air Agency for impacts related to emissions into the
air. Soil on the project site was previously treated for high concentrations of
arsenic. Sampling and analysis of the soil in January 2008 by Landau
Associates indicates that arsenic levels in the soil are now below 5
milligrams per liter, a level at which the soil may be disposed of as solid
waste. The applicant shall properly store, sample, and dispose of excavated
material according to state and federal laws.

H:\Planned Action SEPA\Boeing- Isaacson Mound Removal\E08 -011_Boeing Mound Removal_SR.doc
(3)
•
Construction of new impervious surfaces —New impervious surface
proposed on the site, once the soil excavation and removal and installation
of water quality systems is complete. New impervious surfaces will replace
areas of the site which were previously impervious, resulting in no net
increase in the amount of impervious surface on the project site.
(4) Generation of stormwater from the creation of impervious surfaces that will
not be infiltrated on site— No change in the volume or peak flows of
stormwater is anticipated with this project, and stormwater will be collected
on site and treated through new water quality systems to be installed with
this project, prior to being discharged to the Duwamish River from an
outfall located on the Boeing Thompson property located to the south.
Stormwater management shall comply with the 1998 King County Surface
Water Design Manual.
B. Is the proposal consistent with the applicable sections of the Tukwila
Comprehensive Plan?
TMC 21.04.154 requires that the Comprehensive Plan policies that are to be
reviewed are those identified in the "Integrated GMA Implementation Plan and
Environmental Impact Statement for the Tukwila Manufacturing/Industrial Center."
Specifically, the proposed project meets the following policy:
. Policy 11.1.2: Assist landowners in remediating site problems caused by
contaminated soil.
III. CONCLUSION
The current proposal to demolish and excavate an asphalt and concrete - capped soil mound
covering a 4.6 -acre area, install water quality improvements, and to repave the area with
asphalt, is consistent with the criteria for approval as a Planned Action. There is currently no
use planned for the site, other than a vacant lot, which is a permitted use in the MIC/H zone.
Work proposed with the underlying permit satisfies all other criteria contained in TMC
21.04.152. Proposed actions associated with the proposal are consistent with Tukwila's
Comprehensive Plan, and all impacts associated with the current proposal will be mitigated.

REVIEWERS: Please specify how the attached plans conflict with your ADOPTED
development regulations, including citations. Be specific in describing the types of changes you
want made to the plans. When referencing codes, please identify the actual requirement and
plan change needed.
The Planning Division review does not supplant each department's ability to administer its own
regulations and permits. However, project consistency at the Planning review stage is
important to minimize significant later design changes. More than minimal design changes
require further Planning Commission review, even if alteration is required to satisfy a City
requirement. This further review is typically a minimum 60 -day process.
Requirements based on SEPA (e.g., not required by an adopted development regulation)
MUST identify the impact being mitigated, the policy basis for requiring mitigation, and the
method used to calculate the mitigation required. Calculations of project impacts and the
mitigation required (e.g., water capacity, road level of service analyses, or turning analyses)
may be required of the applicant.

3 -0
Will the project require work, during any time of the project, below the ordinary high water
mark of a watercourse or the Green/Duwamish or Black Rivers or in wetlands? Ordinary high
water mark is the mark that is found by examining the bed and banks of a stream and
ascertaining where the presence and action of waters are so common and usual as to distinctly
mark the soil from that of the abutting upland, in respect to vegetation (see TMC Chapter 18.06,
Page 18 -15). Please circle appropriate response.
NO - Continue to Question 4 -0
YES - Continue to Question 3 -1 (Page 5)

Part B: Please answer each question below for projects that include grading. Review each
question carefully, considering all phases of your project including, but not limited to construction,
normal operation, potential emergency operation, and ongoing and scheduled maintenance.
Continue to the next question as directed for each No or Yes answer.
1 -1
Will the project involve the modification of a watercourse bank or bank of the
Green/Duwamish or Black Rivers between the ordinary high water mark and top of bank? This
includes any projects that will require grading on any slope leading to a river or stream, but will
not require work below the ordinary high water mark. Work below the ordinary high water
mark is covered in Part C. Please circle appropriate response.
NO -Continue to Question 1 -2
YES - Continue to Question 1 -2
1 -2 Could the construction, operation, or maintenance of the project result in sediment transport off
site or increased rates of erosion and/or sedimentation in watercourses, the Green/Duwamish
rivers, or the Black River? Most projects that involve grading have the potential to result in
increased erosion and /or sedimentation as a result of disturbances to the soil or earth. If your
project involves grading and you have not prepared a Temporary Erosion and Sedimentation
Control Plan specifically designed to retain 100 percent of the runoff (including during
construction) from impervious surface or disturbed soils, answer Yes to this question. If your
project is normally exempt under the Tukwila Municipal Code and would not require the
preparation of a Temporary Erosion and Sedimentation Control Plan, BUT may still result in
erosion or sediment transport off site or beyond the work area, answer Yes to this question.
Please circle appropriate response.
NO Continue to Question 1 -3
YES - Continue to Question 1 -3
1 -3 Will the project result in the construction of new impervious surfaces? Impervious surfaces
include those hard surfaces which prevent or restrict the entry of water into the soil in the
manner that such water entered the soils under natural conditions prior to development; or a
hard surface area that causes water to run off the surface in greater quantity or at an increased
rate of flow from the flow presented under natural conditions prior to development. Such areas
include, but are not limited to, rooftops, asphalt or concrete paving, compacted surfaces, or
other surfaces that similarly affect the natural infiltration or runoff patterns existing prior to
development (TMC 18.06.445). Please circle appropriate response.
NO - Continue to Question 2 -0 (Page 2)
YES Continue to Question 1 -4
City of Tukwila ESA Screening Checklist
Part B (continued)
1 -4 Will your project generate stormwater from the creation of impervious surfaces that will not be
infiltrated on site? For the purpose of this analysis, infiltration includes the use of a stormwater
treatment and management system intended to contain all stormwater on site by allowing it to
seep into pervious surface or through other means to be introduced into the ground. If your
project involves the construction of impervious surface and does not include the design of a
stormwater management system specifically designed to infiltrate stormwater, answer Yes to
this question. Please circle appropriate response.
NO - Continue to Question 2 -0 (Page 2)
