RESOLUTION NO.
A RESOLUTION of the City Council of the
City of Kent, Washington, endorsing King, County
Flood Control District Executive Committee's
decision to recommend repair and reconstruction of
the Briscoe-Desimone levee to the King County
Flood Control District Board of Supervisors in,
accordance with the project proposal developed by
the city of Kent,'
RECITALS
A. The King County Flood Control District ("District") was established in
April, 2007 by ordinance 15728 of the Metropolitan King County Council to
protect public health and safety, regional economic centers, public and
private properties and transportation corridors. The District is an
independent special purpose district and will be instrumental in addressing
the backlog ,of maintenance and repairs to levees and revetments,
acquiring repetitive loss properties and other at-risk floodplain properties,
and improving countywide flood warning and flood prediction capacity.
B. The District has been considering a levee repair and reconstruction
project in the city of Kent at the "Briscoe-Desimone" levee along the east
bank of the Green River between S. 200th St. and S. 180th St. These
needed levee improvements are urgent and critical. This levee protects a
large industrial and commercial area of Kent, Tukwila, and Renton, and

Resolution
four reaches do not meet minimum federal levee safety standards. The
City takes the safety of its residents and businesses extremely seriously,
and that is the primary reason why this work must be conducted
immediately. There are approximately 100,000 jobs in the Lower Green
River Valley, and they, along with others throughout the region, would be
impacted by a flood event.
C. The City and King County have developed two separate approaches
to repairing and reconstructing this section of levee. The County's proposal
to repair the four deficient reaches of this levee contemplates a wider levee
setback and is over four times more expensive than the City's proposal
(approximately $71 million) due to the amount of;real estate that must be
purchased and number of businesses that must be removed. The'County's
cost estimate is based on a conceptual plan, which may result in significant
fluctuations in the cost estimates as the project proceeds. Additionally, the
County has not developed a plan to acquire that funding. The City has
developed detailed geoteehnical and hydraulic studies along with 30%
design plans for its levee repair and reconstruction proposal. The City's
cost estimate to complete the improvements needed to bring this levee up
to federal standards is $17, million, including $1 million in new riverbank
vegetation for salmon habitat.
D. There are three federally listed endangered salmon species which
live in the Lower Green River and rely on the riverbank habitat for their
survival. The City proposal allows for stream bank planting of native trees
and shrubs which will improve the habitat for these fisheries without
detrimentally affecting the flood protection provided by the setback
floodwall.

Resolution
E. There is a $7 million state grant for this project which is set to
expire in approximately five months, along with $14 million in District
budgeted funds for this levee between 2013 - 2015.
F. Because of the discrepancies between the two plans, the District
hired a qualified, neutral third party, Dr. Robert B. Gilbert, PhD, P.E., D.GE,
from the University of Texas at Austin, to analyze and review both plans.
Dr. Gilbert is a nationally recognized expert on levee floodwall design
requirements, known for his extensive work analyzing,floodwall issues and
failures caused by Hurricanes Katrina and Gustav, and for his subsequent
involvement as part of a national team to develop new national design
standards for floodwall design and construction. : Dr. Gilbert found that
both proposals met the most current national design standards. His
overwhelming conclusion is that the City's proposal is the most cost
effective means to improve the deficient reaches of the levee to meet
federal standards as part of the long term; goal of improving the flood
protection throughout the Green River Valley.
G. On Thursday, February 7, 2013, the District's Executive Committee
met i to select a project (proposal, and at this meeting, the Executive
Committee recommended to the Flood Control District Board of Supervisors
that Kent's„approach was the preferred proposal.
NOW THEREFORE,' THE CITY COUNCIL OF THE CITY OF KENT,
WASHINGTON, DOES HEREBY RESOLVE AS FOLLOWS:

and critical.
b) The City's proposed setback floodwallr is significantly less

Briscoe-Desimone levee that takes advantage of existing state
and District funding.
d) The City's design method has been approved by Dr. Robert B.
Gilbert, PhD, P.E. D.GE, the District's consultant expert on
levees.
e) The short term flood protection provided by the City's setback
floodwall is comparable to the County's setback levee.
f) The benefits to fish provided,by the City's setback flood wall is
comparable to the County's setback levee.
g) The comparisons made by; Dr. Gilbert and the decision of the
District's Executive Committee to recommend Kent's Briscoe-
Desimone Levee repair and reconstruction proposal to the District
Board of Supervisors is appropriate and correct.
SECTION 2. - The City Council endorses the District Executive
Committee's decision and concurs that the repairs to the Briscoe-Desimone
