    SEA Stakeholder Advisory Round Table shared policy priorities – 2026 state legislative session

    The SEA Stakeholder Advisory Round Table has outlined shared policy priorities for the 2026 Washington State Legislative Session, addressing the challenges posed by growing operations at Seattle-Tacoma International Airport. Key proposals include restoring funding for noise insulation programs, identifying additional regional airport capacity, improving air quality in nearby South King County communities, and advancing sustainable aviation fuel and clean transportation initiatives. The document reflects a joint effort by the Port of Seattle and near-airport communities to partner with state government on reducing noise, emissions, and congestion impacts.

    Update from Burien Airport Committee

    The City of Burien is calling on Port of Seattle Commissioners to overhaul their decades-old noise insulation program after hundreds of Port-installed soundproofing packages in homes near Sea-Tac Airport have degraded or failed with no repairs made. A 2024 pilot program contacted 3,000 homeowners but evaluated only 30, and none qualified for repair under the Port's narrow federal-funding criteria. Burien is urging the Port to fund a broader replacement program using its own resources, pointing to San Francisco International Airport's locally funded model as a potential template.

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.
