City of Tukwila ESA Screening Checklist
Part A: Please review and answer each question carefully. Consider all phases of your project
including, but not limited to, construction, normal operation, potential emergency operation, and
ongoing and sche duled maintenance. Continue to the next question as directed for each No or Yes
answer.
1 -0
Will the project require any form of grading? Grading is defined as any excavating, filling,
clearing, or creation of impervious surface, or any combination thereof, which alters the
existing ground surface of the earth (see Tukwila Municipal Code (TMC) Chapter 18.06,
Zoning Code, Page 18 -11). Please circle appropriate response.
NO - Continue to Question 2 -0
Continue to Question 1 -1 (Page 3)

Will the project require any form of clearing? Clearing means the removal or causing to be
removed, through either direct or indirect actions, any vegetation from a site (see Chapter
18.06, Page 18 -8). Please circle appropriate response.
NO - Continue to Question 3 -0
YES Continue to Question 2 -1 (Page 4)
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.
41r) Continue to Question 4-0
YES - Continue to Question 3-1 (Page 5)
4 -0
Will the project result in the processing or handling, storage, or treatment of hazardous
substances? This does not include the proper use of fuel stored in a vehicle's fuel tank.
Hazardous substances are any liquid, solid, gas, or sludge, including any material, substance,
product, commodity, or waste, regardless of quantity, that exhibits the characteristics or criteria
of hazardous waste as defined by Washington Administrative Code 173 -303 (see TMC Chapter
18.06, Tukwila Zoning Code, Page 18 -11). This includes fuel or other chemicals stored on -site
during construction. Please circle appropriate response.
NO - Continue to Question 5-0
0 - Continue to Question 5-0
5 -0
Will the project result in the withdrawal, injection, or interception of groundwater? Examples
of projects that may affect groundwater include, but are not limited to: construction of a new
well, change in water withdrawals from an existing well, projects involving prolonged
construction dewatering, projects installing French drains or interceptor trenches, and sewer
lines. For the purpose of this analysis, projects that require a geotechnical report pursuant to the
requirements of TMC 18.45.060 and 18.45.080E.4, or would require a geotechnical report if not
exempt under TMC 18.45.080A, should answer Yes. Please circle appropriate response.

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.
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.
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 (see TMC
Chapter 18.06, Tukwila Zoning Code, Page 18 -12). 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. Please circle
appropriate response.

SEPA Lead Agency on Metro Transit's South Base Remodeling Project
Dear Mr. Beeler:
King County Metro Transit is planning to remodel a portion of the Operations building at
King County Metro Transit's South Operating Base at 12000 East Marginal Way South in
Tukwila. According to Tukwila's Department of Community Development staff, the
project can be reviewed under SEPA as a Planned Action, per WAC 197 -11 -172, utilizing
Tukwila's Manufacturing Industrial Center Environmental Impact Statement issued in
1998.
King County would like to transfer SEPA Lead Agency status to the City of Tukwila in
order to take advantage of the simplified review process allowed under the Planned Action
provision. Please call me at (206) 684 -1166 if you would like to discuss this further.
Thank you.
Sincerely,

INFORMATION
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.
This current subarea plan/EIS updates and extends the previous analysis of the corridor's Boeing
properties (about 650 acres) to the entire MIC subarea (about 1,370 acres). It also builds on the
information developed for the City's Comprehensive Plan and Comprehensive Plan EIS efforts of
1994.
The Proposed Action applies the "planned action" option for SEPA review as the center of a permit
streamlining program of early, comprehensive environmental review, and supporting capital and
regulatory revisions.
REQUIREMENTS: Planned actions are developments which satisfy all of the criteria in TMC
21.04.152 (Planned Actions Identified). A proposal must initially qualify as a planned action, then a
second screen to ensure mitigation of all significant negative environmental impacts must also be
satisfied.
The initial qualification criteria are summarized below.
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 36.70A.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.
PROCEDURES: A Planned Action application form may be submitted with the underlying
development permit. Within 28 days of receiving your application, City staff determines if it is
complete. If not, you will be mailed a letter outlining what additional information is needed.
City staff will review the development for substantive impacts and consistency with the
Comprehensive Plan. Additional materials, which are typically submitted in a standard SEPA
process, will be required. The SEPA Responsible Official will decide if a development is a planned
action.

6. Give brief, complete description of your proposal, including the proposed
uses and the size of the 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. Section E requires a
complete description of the objectives and alternatives of your proposal and
should not be summarized here.
The project involves remodeling a portion of the Operations building and
Vehicle Maintenance building at King County Metro Transit's South Operating
Base. The improvements at the Operations building include adding
approximately 3,600 square feet of new floor area at the main entrance to the
building and on the opposite side of the building, and interior modifications
creating more space. The improvements are intended to ease the flow of
workers' movement through that portion of the building.
The improvements within the Vehicle Maintenance building include adding a
level within the existing structure creating two floors where there is currently
one (ceiling height is adequate to accommodate the new floor). The
improvement adds approximately 1,000 square feet of work area.
The project includes redesign of existing landscaping and results in the loss of
approximately 500 square feet of pervious landscaped area.

8. Does this proposal lie within an area designated on the City's
Comprehensive Land Use Policy Plan Map as environmentally sensitive?
No.
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)?
N /A.
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 prime farmland.
Soils on the site consist of mainly urban fill which is overlying alluvial
deposits.

immediate vicinity? If so, describe.
No.
e. Describe the purpose, type, and approximate quantities of any filling
or grading proposed. Indicate source of fill.
The project involves minimal earth moving to accommodate a minor
increase in footprint to the Operations building and changes in
landscaping. Total amount of earth to be moved is approximately 185
cubic yards (117 cubic yards of cut bank to be removed and 68 cubic yards
of fill volume replaced for landscaping and foundations).
f. Could erosion occur as a result of clearing, construction, or use? If so,
generally describe.
Agency Comments:
6
Applicant Responses:
g.
• •
Minor erosion of piled materials could occur during construction.
However, construction erosion will be controlled through the use of best
management practices (such as covering piled materials).
No erosion will occur after construction.
About what percent of the site will be covered with impervious
surfaces after project construction (for example, asphalt or
buildings)?
The project will result in a minor net reduction in the amount of
impervious surface at the site. The site is currently roughly 95 percent
impervious surface. The project will result in the loss of approximately
500 square feet of pervious area.
h. Proposed measures to reduce or control erosion, or other impacts to
the earth, if any:
Measures to reduce or control erosion will include covering exposed soils.
Erosion control methods will be used in accordance with accepted best
management practices and City of Tukwila development standards.
2. Air
a. What types of emissions to the air would result from the proposal (i.e.,
dust, automobile emissions, odors, industrial wood smoke) during
construction and when the project is completed? If any, generally
describe and give approximate quantities if known.
During construction, exhaust emissions would result, on a temporary basis,
from the operation and movement of gas -and diesel - powered vehicles.
b. Are there any off -site sources of emissions or odor that may affect
your proposal? If so, generally describe.
No.
c. Proposed measures to reduce or control emissions or other impacts to
air, if any:
Construction vehicles and equipment would have standard emission
control devices. Other measures to minimize air quality impacts would
include avoiding prolonged idling of construction vehicles, using electric
