    Roundtable engagement guidance: How the FAA engages with Airport and Community Roundtables

    This FAA guidance document explains how Airport and Community Roundtables work as forums where local governments, communities, and aviation stakeholders can collaboratively discuss concerns about nearby airport operations. The FAA participates in these roundtables to provide technical expertise but does not vote on issues, and roundtables can submit formal recommendations for changes to flight procedures or airspace operations. Any recommended changes must go through a thorough FAA review process, including safety and environmental assessments, and can take several years to implement.

    House Bill 1948 – Environmental Justice for Large Port Districts

    Washington House Bill 1948 (2025) would require large port districts — such as the Port of Seattle, which operates Sea-Tac Airport — to develop environmental justice implementation plans and community engagement plans aimed at reducing health and environmental disparities for overburdened communities affected by airport noise and other port activities. The bill mandates that these plans include specific goals, measurable metrics, and outreach strategies to ensure meaningful participation from vulnerable populations, including people with limited English proficiency. Port districts would also be required to conduct environmental justice reviews for major capital projects valued at $8 million or more, or any action that increases the number of airport gates.

    South King County Community Impact Fund: Highline Forum Presentation

    The South King County Community Impact Fund (SKCCIF) is a $14 million Port of Seattle investment running from 2025 to 2029, aimed at improving quality of life for historically underserved communities in South King County. The fund is divided across three programs: Economic Opportunities for Communities (70%), Environmental Improvements (20%), and Diversity in Contracting (10%). Its mission is to remove systemic barriers by expanding access to living-wage jobs in Port-related industries, enhancing public spaces, and supporting community-led projects.

    SAMP Comments: Stuart Jenner Public Comment on 2024 Draft Environmental Assessment

    Seatac Airport neighbor Stuart Jenner submitted public comments in December 2024 criticizing the Port of Seattle's Sustainable Airport Master Plan (SAMP), arguing that citizens were given inadequate time to review over 4,000 pages of documents and that an Environmental Impact Statement—not merely an Environmental Assessment—is needed to properly evaluate the plan's effects on nearby residents. Jenner raises concerns about opaque computer models used to claim a nearly 50% increase in passenger traffic would have no environmental impact, shifting baseline comparisons that ignore past promises made during the third runway approval, and the absence of project cost information. He calls on Port Commissioners and the FAA to extend the public comment period and subject the plan to greater independent scrutiny.

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.
