    City of Des Moines Letter to Port Of Seattle: Comments on SAMP Draft Environmental Assessment

    The City of Des Moines, Washington submitted formal comments to the Port of Seattle in December 2024, raising concerns about the environmental and health impacts of Seattle-Tacoma International Airport's planned growth. The city warns that by 2032, annual flight operations will increase by nearly 20%, expanding the noise exposure zone and raising the number of residents affected by significant aircraft noise from roughly 14,000 to nearly 22,000—with most of that burden falling on Des Moines residents. The letter calls on the Port and FAA to extend public comment periods, pursue meaningful noise mitigation measures such as sound insulation for homes and schools, and engage more collaboratively with impacted communities rather than treating public review as a formality.

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.
