    HB 1791: Peace With Honor

    The passage of 1791-S.PL acknowledges that the battle for a second airport process (known as the CACC) is lost. But, let’s pretend it’s not. However, if previous efforts (such as the Flight Plan Study of 1989) are any indication, HB-1791 will not only result in years of delay, it will actually work to accelerate the pace

    SHB 1791 – H AMD 174: Amendment to Modify Intent Statement on Commercial Aviation Facility Impacts and Sea-Tac Alternatives

    This 2023 Washington State House amendment (adopted March 8, 2023) updates the intent statement of SHB 1791 to more specifically acknowledge the environmental, health, social, and economic impacts that a major commercial airport can have on surrounding communities. It references a Puget Sound Regional Council study projecting that by 2050, central Puget Sound will face a significant gap between aviation demand and capacity. The amendment emphasizes that exploring alternatives to Seattle-Tacoma International Airport — potentially including new or expanded airports — is critical to meeting future regional transportation needs.

    House Bill 1791: Studying the Need for Increased Commercial Aviation Services (Washington State 68th Legislature, 2023)

    Washington State House Bill 1791 (2023) establishes a new Commercial Aviation Coordinating Work Group to study the state's long-range aviation needs over the next 20 years, replacing the previous Commercial Aviation Coordinating Commission whose work was disrupted by the COVID-19 pandemic. The 19-member work group, appointed by the governor, will evaluate airport capacity across Washington and assess the potential need for a new commercial airport, taking into account community and environmental impacts. The study is particularly focused on meeting growing aviation demand in western Washington, which has direct implications for how future air traffic and infrastructure decisions may affect communities around Sea-Tac Airport.

Read This!

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.
