    Community open house: Burien, Des Moines, and SeaTac demand equity for airport-impacted communities

    The cities of Burien, Des Moines, and SeaTac held a Community Open House to demand equity for communities impacted by Sea-Tac Airport, presenting concerns about a Draft Environmental Impact Statement (DEIS). The cities argue the DEIS fails to adequately address hazardous materials risks—including incomplete PFAS contamination mapping and insufficient evaluation of off-site pollution migration—and does not properly demonstrate how airport expansion affects nearby neighborhoods, parks, and land use. Key deficiencies identified include reliance on future regulatory compliance rather than current evidence, and a lack of clear analysis linking land use conclusions to technical findings.

    Tips for Providing Meaningful Public Comment on the Seattle-Tacoma SAMP Draft EIS

    This document provides guidance for residents near Seattle-Tacoma International Airport (SEA) on how to submit public comments about the Sustainable Airport Master Plan (SAMP) and its Draft Environmental Impact Statement before the July 21, 2026 deadline. It highlights key concerns including aircraft noise, air quality, traffic, and economic impacts on neighboring communities, with sample comment language residents can adapt. A central argument is that the standard DNL noise metric understates the real impact of a 20% increase in flight operations, and that supplemental noise metrics should be used to better reflect residents' daily experiences.

Issues

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.
