    Four-City Joint Comment Letter on Seattle-Tacoma International Airport SAMP Draft Environmental Assessment

    Four cities near Seattle-Tacoma International Airport — Burien, Normandy Park, SeaTac, and Des Moines — submitted formal comments in December 2024 objecting to the airport's Sustainable Airport Master Plan Environmental Assessment. The cities warn that planned growth will increase annual flight operations by nearly 20% by 2032, expanding the noise impact zone and exposing an estimated 22,000 residents to significant aircraft noise, up from about 14,000 in 2022. They call on the Port of Seattle to extend public review periods, improve its sound insulation program, and take proactive steps to protect the low-income and minority communities most burdened by airport noise.

Key projects include a new passenger terminal and gates, taxiway extensions, cargo facility changes, and employee parking updates. The cities of SeaTac, Burien, Des Moines, and Normandy Park are collaborating to submit technical comments on the plan before the December 13, 2024 deadline.

    North Sea-Tac Park Special Council Meeting Presentation

    At a Special Council Meeting on August 13, 2024, the City of SeaTac presented an overview of efforts to potentially acquire North SeaTac Park (NSP) from the Port of Seattle, following a 2022 City Resolution exploring its feasibility. The presentation outlined what is known and unknown about the park, noting that two letters had been sent to the Port Commission and a formal discussion was planned for an upcoming Joint Airport Communities (JAC) meeting. Council was asked to provide direction on how to prioritize the acquisition effort relative to other City projects, as no detailed feasibility analysis had yet been completed.

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.
