Strategic discussion on future federal grant opportunities. BACKGROUND Conversations on the Strander Blvd Extension started in the 1980s. The City of Renton had the lead at that time and completed Phases 1 and 2 of the project. The City of Tukwila was the lead on Phase 3. The purpose of the project was to meet growth management concurrency standards, and to move 22,500 vehicles per day off South 180th Street, Grady Way and 1-405. The project was planned to complete the last 1,500 feet of an east -west connection by constructing a safe crossing of a key regional railroad line. On February 16, 2016, Council approved BergerABAM to begin preliminary design of the Strander Blvd Extensions Phase 3 project. During the preliminary engineering phase, the project became more complicated due to unforeseen circumstances and the cost estimate increased. In 2019, design was stopped at 30% in order to conduct the Value Engineering (VE) Study, which was recommended by the Washington State Department of Transportation (WSDOT). BergerABAM (now part of WSP) was selected as the City's VE study consultant. Based on information provided in the VE study, the total project costs increased from $39,102,000 to $83,781,626, more than double the original estimate. Council Decision to Stop Project At the June 10, 2019, Committee of the Whole meeting, three options were presented for Council to consider by the Public Works Director and the consultant, BergerABAM: Option 1: Continue with the current design of a 4 -lane road. $5 to $10 million potential cost savings identified by VE Study. Option 2: Incorporate value engineering proposals of a 2- lane road with no seal, if possible, and continue design. This option would eliminate walls on one side of the structure. $10 to $25 million potential cost savings identified. Option 2 was the recommendation of City Administration.
