    Commercial Aviation Coordinating Commission Report to Legislative Transportation Committees: 2023 Final Recommendation

    ★ 32
    The Commercial Aviation Coordinating Commission (CACC) submitted its final report to the Washington State Legislature in June 2023, concluding that future commercial aviation capacity needs can only be met by identifying a new greenfield airport site, as no existing finalist location gained sufficient community support. The Commission was evenly divided on whether a new facility could be operational by 2040, with most members believing completion beyond 2050 is more realistic. The report and survey results were handed off to a follow-on work group established under ESHB 1791 to continue the site selection process.

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.
