    25-7439 Petition for Review of Agency Order – City of Burien, City of Des Moines, and City of SeaTac v. FAA

    Three Washington cities near Seattle-Tacoma International Airport — Burien, Des Moines, and SeaTac — filed a legal challenge on November 24, 2025, asking a federal appeals court to review the FAA's September 2025 decision approving near-term construction and expansion projects under the airport's Sustainable Airport Master Plan. The cities argue the FAA's environmental finding, known as a FONSI/ROD, should be scrutinized by the Ninth Circuit Court of Appeals, which has jurisdiction because the cities are located within that circuit. The petition was filed on the last allowable day of the 60-day filing window, as the original deadline fell on a Sunday.

    SEA Sustainable Airport Master Plan: ILA, Budget Amendment, Letters of Engagement (AB 6794)

    The cities of SeaTac, Burien, Des Moines, and Normandy Park are jointly challenging the FAA's environmental review of the Port of Seattle's Sustainable Airport Master Plan (SAMP), arguing that a September 2025 Finding of No Significant Impact (FONSI) failed to adequately address their concerns about airport expansion impacts. The SeaTac City Council is being asked to approve a budget amendment of up to $350,000, authorize an Interlocal Agreement among the four cities, and hire two law firms to advocate for airport-affected communities. The action reflects ongoing efforts by neighboring cities to ensure environmental impacts of SEA airport growth are properly evaluated under both federal (NEPA) and state (SEPA) law.

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.
