    Regional Aviation Baseline Study

    The Regional Aviation Baseline Study, conducted by the Puget Sound Regional Council, examines 29 airports across King, Snohomish, Kitsap, and Pierce counties to understand how aviation activities interact with communities and the broader regional economy. The study identifies each airport's role, gathers stakeholder input on aviation and airspace constraints, and sets the groundwork for future regional aviation planning. While Sea-Tac Airport serves as the region's primary large hub, the study provides context for understanding how operations across all regional airports—and their associated noise and community impacts—fit into the larger Puget Sound air transportation network.

    Adoption of 2020 local and regional policy priorities

    This February 2020 Port of Seattle Commission memorandum outlines the organization's top local and regional policy priorities for 2020, including industrial lands protection, clean fuels and sustainability, cruise terminal development, and equity and inclusion initiatives. The document covers Port-wide priorities such as reducing carbon emissions, supporting regional transportation mobility, and workforce development across King County. While the document addresses broad Port operations and planning, it does not specifically focus on Sea-Tac Airport noise policy.

    Regional Aviation Baseline Study: Working Paper 1 — Airport and Aviation Activity

    This 2019 Working Paper, prepared by WSP for the Puget Sound Regional Council, examines airport and aviation activity across the greater Seattle-Tacoma region as part of a Regional Aviation Baseline Study. It covers commercial aviation, general aviation, and air cargo trends and forecasts, along with multimodal access and economic context for the region's airports. The study establishes baseline data and metrics to inform future regional aviation planning and policy decisions.

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.
