    Final Highline Forum agenda: SR 509 Project & Sea-Tac Air Quality Initiatives

    The Highline Forum held on July 26, 2017, at SeaTac City Hall brought together community stakeholders, city officials, and representatives from WSDOT and the Port of Seattle to discuss key regional topics including the SR 509 Puget Sound Gateway Program, aircraft altitude concerns, and air quality initiatives near Sea-Tac Airport. Presentations were delivered by Port of Seattle staff covering noise programs and environmental initiatives, alongside updates on SeaTac's economic development. The meeting provided a public forum for emerging issues and planning for future discussions on airport-related impacts to surrounding communities.

    SR 509: Corridor Completion/I-5/South Access Road final environmental impact statement and Section 4(f) evaluation

    This January 2003 Final Environmental Impact Statement evaluates proposed highway improvements in southwest King County, Washington, including an extension of SR 509 and upgrades to I-5 between South 210th Street and South 310th Street to improve regional access to Seattle-Tacoma International Airport. Three build alternatives and a No Action Alternative are assessed, with the SR 509 extension designed to accommodate two general purpose lanes and a center high-occupancy vehicle lane in each direction. The project was jointly prepared by the Federal Highway Administration, Washington State Department of Transportation, Port of Seattle, King County, and the Cities of SeaTac and Des Moines.

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.
