MEMORANDUM
TO: PhD Fraser, Gary S
FROM: Michael Jenkin
DATE: June 3, 1998
RE: E98-0016, SEPA application for replacement of piping in a
watercourse, 33rd. Ave. S / S. 132nd. St.
Upon review of the SEPA application referenced above, the Department of
Community Development has determined that the project to replace an existing
45 foot storm drain is exempt from SEPA, under WAC 197-11-800(3). Based
upon the application materials that were submitted, your project involved
replacing a 45 foot section of existing pipe, near the referenced intersection.
This existing 12 inch pipe is used to convey both storm water and what appears
to be year-round ground water.
As the project does not involve any acts other than replacing the existing piping
with new materials and does not increase the extent of piping, the project falls
within the exemptions indicated in the referenced WAC. This exemption covers
both ordinary maintenance of existing facilities or structures as well as minor
repair, alteration or maintenance of structures on lands covered by water.
Accordingly, I will close out this application file and indicate it as exempt.

Preliminary Environmental Checklist.
app -Oe ((O
WAC 197-11-960 Environmental Checklist
Purpose of Checklist:
The State Environmental Policy Act (SEPA), chapter 43.21 RCW, requires all governmental agencies
to consider the environmental impacts of a proposal before making decisions. An environmental
impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts
on the quality of the environment. The purpose of this checklist is to provide information to help the
agency, citizens, and other reviewers identify impacts from the proposal, to possibly reduce or avoid
impacts from the proposal, and to help the agency decide whether an EIS is required.

7. Plans for future additions, expansion or further activity related to or connected with this
proposal:
No future expansion is planned
8. Environmental information that has been prepared, or will be prepared, directly related to
this proposal:
None known.
9. Applications that are pending for governmental approval of other proposals directly
affecting the property covered by the proposal:
None known.
10. List of governmental approvals or permits that will be needed for the proposal:
None anticipated
11. Brief, complete description of the proposal, including the proposed uses and the size of the
project and site:
The existing storm drain crossing -of 33rd Avenue South is plugged by a tree root, causing
drainage to overtop the road during major storms. This proposal is to remove and replace
approximately 45 feet of 12 -inch. diameter storm drain to eliminate this localized flooding
during storms. The new storm drain will be placed on the exact same line and grade as the
existing pipe.
The storm drain proposed for replacement extends from a catch basin on the west side of 33'
Avenue South to an open channel outfall in a drainage course which receives stormwater
runoff and seasonal groundwater flows. Downstream of the outfall, water flows through
approximately 15 feet of open channel and then is piped across Pacific Highway South and
eventually into Riverton Creek.
A copy of the preliminary plan is attached for review.
12. Location of the proposal, including the street address, if any, and section, township and
range, if known; a legal description, site plan, vicinity map and topographic map, if
reasonably available:
The project site is located in the City of Tukwila, approximately 75 feet north of the
intersection of 33rd Avenue South with South 132"d Street.
