    Start aviation noise working group meeting summary

    The StART Aviation Noise Working Group met in February 2025 to review Seattle-Tacoma International Airport's Late Night Noise Limitation Program, which tracks aircraft noise between midnight and 5 AM and found 8% of operations exceeded thresholds in Q4 2025. The group decided against expanding the program to cover 11 PM–midnight, as most flights in that hour already use quieter aircraft and the change would triple monitored operations with little noise-reduction benefit. Additional updates covered a significant drop in propeller aircraft turns over Burien, progress on the Sound Insulation Program, and action items including a new 5–6 AM operations analysis and a multi-year trends chart.

    Airport Advisory Committee agenda item

    The City of Des Moines, WA is proposing the formation of a permanent Airport Advisory Committee to advise the City Council on matters related to Seattle-Tacoma International Airport, including review of the Sustainable Airport Master Plan (SAMP), potential interlocal agreements with airport partners, and the city's strategy with the Port of Seattle. The committee would consist of at least three Des Moines residents, including at least one City Council member, and would meet quarterly to evaluate airport-related issues and provide recommendations. Staff submitted the proposal for Council approval at the February 6, 2025 meeting, following a unanimous Council vote in October 2024 to establish such a committee.

    Bill request S-0809.1/25: Reducing environmental and health disparities and improving the health of Washington state residents in large port districts

    This proposed Washington State bill would require large port districts — such as those operating major airports like Sea-Tac — to develop and adopt environmental justice implementation plans aimed at reducing health and environmental disparities in surrounding communities. The plans must include specific goals, measurable metrics, community engagement strategies, and timelines for incorporating environmental justice considerations into port activities. It also establishes oversight for major capital projects valued at $8 million or more, or any actions that increase the number of airport gates.

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.
