    Resolution No. 2626: A resolution establishing planning and developmental policies relating to Sea-Tac International Airport and its vicinity

    ★
    Resolution No. 2626, adopted by the Port of Seattle Commission on June 8, 1976, formally accepted the Sea-Tac/Communities Plan as a guide for developing Sea-Tac International Airport in a way that maximizes compatibility with surrounding neighborhoods. The resolution directed Port staff to pursue federal funding for land acquisition in flight path zones, establish an aircraft noise monitoring system, and launch a pilot acoustic insulation program for nearby homes. Total noise abatement efforts were estimated to cost approximately $50 million over a ten-year period, with funding expected from airport revenues and federal assistance.

    STNI Comments on the SAMP Near-Term Projects Draft Environmental Impact Statement, May 2026

    Sea-Tac Noise.Info (STNI) submitted formal comments in August 2026 challenging the Port of Seattle's Draft Environmental Impact Statement for its Sustainable Airport Master Plan, arguing the review is procedurally and analytically flawed. Key concerns include insufficient project design detail to support impact conclusions, missing hazardous materials surveys for 12 buildings slated for demolition, withheld technical documents that the public cannot independently verify, and the exclusion of over $5 billion in prior airport expansion projects from cumulative impact analysis. STNI requests the Port complete additional surveys and design work, extend the public comment period, and recalculate growth impacts using a pre-Third Runway baseline before finalizing the EIS.

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.
