City of Tukwila Public Works Department - Henry Hash, Director INFORMATIONAL MEMORANDUM TO: Transportation and Infrastructure Committee FROM: Henry Hash, Public Works Director /;✓r° BY: Steve Carstens, Senior Program Manager CC: Mayor Ekberg DATE: March 23, 2018 SUBJECT: Strander Blvd/SW 27th St Extension Phase 3 Project Project No. 98610403 Bridge Program Funding Discussion Allan Ekberg, Mayor ISSUE Construction of the Strander Blvd/SW 27th St Extension Phase 3 Project is expected to cost a minimum of $39 million. BACKGROUND The Strander Blvd Extension Project was designed to be in constructed in three phases. Phase 1 and 2 were constructed by the City of Renton for approximately $26 million. The remaining Phase 3 was left to Tukwila to construct. To date, the City has received over $4.5 million to design the project. In the 2016 LID feasibility review, it was determined that a special benefit area could generate between $1.5 to $4 million in revenue, however, it would not cover parcels located in the City of Renton and adjacent to the project unless an Interlocal Agreement was negotiated with Renton. In 2016, the NW Arena Project was also being considered. DISCUSSION Tukwila has received funding to perform design and right-of-way and is now working on the preliminary engineering plans. For Strander Phase 3 to proceed, the City, despite receiving future grant funds, would be required to significantly participate in the funding. The cost of this participation could exceed $7 million. There are two off -ramps where the city could stop the project; one is right now before finishing design. The City could elect to terminate the project and return any reimbursed design grant funds. The other option to stop the project is at the end of design and not proceed immediately to construction in 2020. This would allow the City up to 10 years to begin construction of Strander Blvd Phase 3 before triggering events that would require expended grant funds to be returned. This second option also has construction funding implications — funds secured for construction in 2020 would have to be relinquished if the City were to defer project construction to a later date and there would be no guarantee that these funds would be available in the future. The Tukwila bridge program will see the need for project prioritization in the upcoming years. Currently, there is a projected shortfall of funds needed of over $16 million for various bridge projects. Currently, the bridge program has federal mandates to inspect and maintain the City's bridge assets. Two of the highest priorities of the program are the emergency repair on the S 196th/200th Street Bridge and the replacement funding for 42nd Ave S truss Bridge over the Duwamish River.
