    Interlocal agreement for the construction of the Puget Sound Gateway Program

    The City of SeaTac entered into an interlocal agreement (Agreement No. 18-A144) with the Washington State Department of Transportation (WSDOT) to provide up to $4,000,000 in local matching funds for the construction of the Puget Sound Gateway Program, specifically the State Route 509 Extension Project. The funding is split into two stages: up to $2,000,000 in real estate and/or cash for the SeaTac Access Local Nexus Project, and up to $2,000,000 in cash toward the South 188th Street Interchange once construction sales tax is received. WSDOT is responsible for designing, constructing, and managing the project, which includes improvements such as interchange ramps and access roads largely within the City of SeaTac.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
