    Commercial Aviation Work Group Annual Report

    The Washington State Commercial Aviation Work Group submitted its first annual report to the Legislature in November 2024, summarizing early organizational steps taken since its July 2024 launch. The group, created to study airport capacity needs across Washington State over the next 20 years, held only two meetings in 2024 and remained understaffed, with just 13 of 19 required voting positions filled. Notably, Governor Inslee directed that expanding existing airports must be fully considered before any new airport site is selected, with SeaTac explicitly excluded from capacity expansion discussions.

    CACC Final Meeting: Commission Member Survey and ESHB 1791 Recap

    This document presents the agenda and key materials from the final meeting of Washington State's Commercial Aviation Coordinating Commission (CACC), covering public engagement efforts, a recap of legislation ESHB 1791, and a commission member survey. The bill, signed by Governor Inslee, created a new Commercial Aviation Work Group (CAWG) to replace the CACC, though several sections were vetoed, including provisions for the CAWG task list, funding transfer, and immediate effect. A survey of commission members showed strong support (13 to 1) for the need for a new greenfield airport site to meet future commercial aviation capacity needs in the region.

    Engrossed Substitute House Bill 1791: Commercial Aviation Work Group

    Washington State's Engrossed Substitute House Bill 1791, passed in 2023, establishes a new 19-member Commercial Aviation Work Group to study the state's long-term airport capacity needs, replacing the earlier Commercial Aviation Coordinating Commission. The bill responds to projections that by 2050, demand for flights in the central Puget Sound region will exceed Seattle-Tacoma International Airport's capacity, and directs the group to explore alternatives—including building or expanding other airports. The legislation acknowledges that any new airport site would carry significant environmental, health, and community impacts requiring decisions from federal, state, and local governments.

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.
