    (Draft) Joint letter from City of Burien, City of Des Moines, and City of SeaTac to Port Of Seattle Commissioners regarding SAMP environmental review

    The mayors of Burien, Des Moines, and SeaTac jointly wrote to Port of Seattle Commissioners in 2026 to challenge the claim that airport expansion projects outlined in the Sustainable Airport Master Plan (SAMP) would have no significant impact on neighboring communities. The letter highlights concerns about aircraft noise, air pollution, traffic, and disproportionate burdens on historically disadvantaged residents living closest to the airport. The cities also demand that the public comment period for the Draft Environmental Impact Statement be extended from 60 to at least 120 days to allow for meaningful community review.

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.
