A RESOLUTION of the City Council of the city of Kent, Washington, endorsing the K1ng County Flood Control D1stnct Execut1ve Committee's decision to recommend repa1r and reconstruction of the Bnscoe-Des1mone levee to the King County Flood Control D1stnct Board of Supervisors m accordance w1th the proJect proposal developed by the c1ty of Kent. RECITALS A. The King County Flood Control District ("District") was established in April, 2007 by ord1nance 15728 of the Metropolitan King County Council to protect public health and safety, reg1onal econom1c centers, public and pnvate properties and transportation corridors. The District is an independent special purpose d1stnct and w1ll be mstrumental m addressmg the backlog of mamtenance and repa1rs to levees and revetments, acquiring repet1t1ve loss properties and other at-nsk floodplain properties, and 1mprovmg countywide flood warning and flood pred1ct1on capac1ty. B. The District has been considering a levee repair and reconstruction project m the c1ty of Kent at the "Bnscoe-Des1mone" levee along the east bank of the Green R1ver between S. 200th St. and S. 180th St. These needed levee Improvements are urgent and cnt1cal. Th1s levee protects a large industnal and commemal area of Kent, Tukwila, and Renton, and four reaches do not meet minimum federal levee safety standards. The City takes the safety of 1ts res1dents and businesses extremely senously, and 1 Briscoe-Desimone Levee Resolution that is the pnmary reason why th1s work must be conducted immediately. There are approximately 100,000 JObs in the lower Green R1ver Valley, and they, along w1th others throughout the reg1on, 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 repa1r the four def1c1ent reaches of th1s levee contemplates a wider levee setback and 1s over four t1mes more expens1ve than the City's proposal (approximately $71 million) due to the amount of real estate that must be purchased and number of busmesses that must be removed. The County's cost est1mate is based on a conceptual plan, wh1ch may result 1n s1gnif1cant fluctuations 1n the cost estimates as the proJect proceeds. Additionally, the County has not developed a plan to acqu1re that fundmg. The City has developed detailed geotechnical and hydraulic stud1es along with 30% des1gn plans for 1ts levee repair and reconstruction proposal. The City's cost estimate to complete the improvements needed to bnng th1s levee up to federal standards is $17 million, includmg $1 million in new riverbank vegetat1on for salmon habitat. D. There are three federally listed endangered salmon speCies wh1ch live 1n the lower Green River and rely on the nverbank hab1tat for their survival. The City proposal allows for stream bank planting of nat1ve trees and shrubs wh1ch w1ll improve the habitat for these fisheries Without detnmentally affecting the flood protection prov1ded by the setback floodwall. E. There is a $7 million state grant for th1s proJect which IS set to expire in approximately five months, along with $14 million in Distnct budgeted funds for this levee between 2013 -2015. 2 Briscoe-Desimone Levee Resolution F. Because of the d1screpanc1es between the two plans, the District h1red a qual1f1ed, neutral th1rd party, Dr. Robert B. Gilbert, PhD, P.E., DGE, from the Un1vers1ty of Texas at Aust1n, to analyze and review both plans. Dr. Gilbert is a nationally recogmzed expert on levee floodwall des1gn requirements, known for h1s extensive work analyzing floodwall 1ssues and failures caused by Hurncanes Katrina and Gustav and for his subsequent involvement as part of a nat1onal team to develop new national des1gn standards for floodwall design and construction. Dr. Gilbert found that both proposals met the most current nat1onal design standards. His overwhelmmg conclusion IS that the City's proposal IS the most cost effective means to Improve the def1c1ent reaches of the levee to meet federal standards as part of the long term goal of improving flood protection throughout the Green R1ver Valley. G. On Thursday, February 7, 2013, the District's Execut1ve Comm1ttee met to select a proJect proposal, and at this meeting, the Execut1ve Committee recommended to the Flood Control D1stnct Board of Supervisors that Kent's approach w1th technical recommendations from Dr. Robert B. Gilbert, PhD, P.E., DGE, 1s the preferred proposal.

Gilbert, PhD, P.E., DGE, the D1stnct's consultant expert on levees. e) The short term flood protection prov1ded by the City's setback floodwall 1s comparable to the County's setback levee. f) The benefits to f1sh prov1ded by the City's setback flood wall are comparable to the County's setback levee. g) The comparisons made by Dr. Gilbert, and the decision of the D1stnct's Execut1ve Committee to recommend Kent's Briscoe- Deslmone Levee repa1r and reconstruction proposal to the D1stnct Board of Superv1sors, are appropriate and correct. SECTION 2. -The City Council endorses the District Executive Committee's dec1s1on and concurs that the repa1rs to the Bnscoe-Des1mone levee, as recommended by the city of Kent Public Works Department, are the appropnate and correct approach to repair and reconstruct this port1on of the Green R1ver levee. 4 Briscoe-Desimone Levee Resolution SECTION 3. -The Kent City Council 1s interested 1n providing at least one Councilmember in the Reg1onal Systemwide Improvement Framework (SWIF) process to ensure meanmgful representation on behalf of Kent's broad economic development and safety interests.
