FORWARD TO NOVEMBER 20, 2017 REGULAR CONSENT AGENDA. E. Grant Acceptance: Non -Transportation Commute Trip Reduction Pilot Program Staff is seeking Council approval of a grant award with WSDOT in the amount of $107,000 to implement a pilot program to reduce regional congestion and improve air quality in Tukwila and South King County. The funding opportunity was designed to pilot the expansion of Transportation Demand Management (TDM) programs beyond traditional Commute Trip Reduction (CTR) affected sites into new markets. King County Metro and the Port of Seattle are providingthe required $25,000 local match. UNANIMOUS APPROVAL. FORWARD TO NOVEMBER 20, 2017 REGULAR CONSENT AGENDA. F. Tukwila International Boulevard Retrofit Implementation Staff updated the Committee on implementation of the community's vision for the Tukwila International Boulevard (TIB) neighborhood and the Congress for New Urbanism (CNU's) recommended action on a rechannelization design. The CNU report suggested that the City change the street design to reduce through -lanes to two from four, allowing on -street parking and bicycle lanes and adding crosswalks. The City contracted with Fehr& Peers to study the impacts associated with the lane removal and potential mitigation. The study found that at least 50% of existing traffic is pass through and unrelated to local business or residences. Traffic diversion will occur on adjacent streets in the order of 42nd Avenue South, Military Road South, 1-5, Des Moines Memorial Drive South, and 51' Avenue South/Macadam Road. By 2030, traffic would increase by 20% under the road diet scenario. The study also found that typical traffic calming measures on side streets would not be effective in preventing the traffic diversion, but intersection diverters or short one- way segments could help. KPG, Inc. prepared three preliminary design options and cost estimates that all include removal of the two lanes plus parking and a bicycle lane. Alternative 1 would add bulb -outs at mid -block pedestrian crossings at a cost of $1,130,000, Alternative 2 would only restripe at a cost of $250-400,000, and Alternative 3 would add crosswalks and bulb -outs at intersections at a cost of $1,270,000. Staff recommends implementing Alternative 2 because it is a low-cost option to help staff evaluate traffic impacts prior to further investment. The Committee discussed the study's findings. Councilmember Robertson suggested diverting traffic further south down by South 130th Street in order to avoid a traffic increase on 42nd Ave S. Councilmember Quinn suggested painting zones and increasing Police speed enforcement, like in Bellevue. He stressed the importance of protecting the residential streets. The Committee did not arrive at a recommendation but requested staff return in 2018 at the Committee level to continue discussing the options. NO RECOMMENDATION. RETURN TO COMMITTEE. G. Final Construction Settlement: Interurban Avenue South Staff is seeking Council approval of a final settlement and Change Order No. 9 with Walsh Construction in the amount of $1,081,259.15 for the Interurban Avenue South Project. Walsh has asserted that the project encountered unexpected impacts and has sought additional compensation, which the City disputed. The parties have been in mediation since June 2017 and this settlement represents the agreed upon terms. Funding for this settlement is aided by an additional $750,000 from the State Transportation Improvement Board and $35,000 in traffic impact fees. With a final contract amount of $8,917,921.31, the City's overage is $165,000. The Committee requested that staff amend the informational memo to clearly show where the $165,000
