The City of Des Moines, Washington outlined its 2025 state legislative priorities, which include several airport-related concerns such as establishing a permanent air quality monitor, funding an independent study on the impacts of the Seattle-Tacoma International Airport Master Plan (SAMP), and expanding sound insulation repair and replacement programs. The city also seeks enhancements to SB5955 and RCW53 to allow unconstrained funding for mitigating public health impacts from airport operations. Additional priorities include public safety funding, property tax reform, replacement of the Redondo Fishing Pier, historic preservation, and development of electric passenger-only ferry routes connecting Des Moines.

The Burien Airport Committee held a meeting on December 17, 2024, to discuss topics related to Sea-Tac Airport noise and expansion policy, including a wrap-up of public comments on the Sustainable Airport Master Plan (SAMP), a possible multi-city response to the SAMP, and potential state-level mitigation legislation. The committee also considered expanding its membership from five to seven members and reviewed a StART (Sea-Tac Airport Roundtable) committee update. Members of the public were invited to participate in person at Burien City Hall, via Zoom, or by submitting written comments in advance.

This document presents formal public comments opposing an FAA Environmental Assessment for expansion projects at Seattle-Tacoma International Airport. The author argues that the stated justification for expansion is misleading, contending that airport growth would not automatically occur without new gates and terminals since FAA safety rules already cap the number of aircraft operations. Additional concerns raised include disproportionate health burdens on nearby communities, unreliable air pollution modeling, inadequate environmental justice analysis, and failure to properly assess cumulative public health and climate impacts.

Seatac Airport neighbor Stuart Jenner submitted public comments in December 2024 criticizing the Port of Seattle's Sustainable Airport Master Plan (SAMP), arguing that citizens were given inadequate time to review over 4,000 pages of documents and that an Environmental Impact Statement—not merely an Environmental Assessment—is needed to properly evaluate the plan's effects on nearby residents. Jenner raises concerns about opaque computer models used to claim a nearly 50% increase in passenger traffic would have no environmental impact, shifting baseline comparisons that ignore past promises made during the third runway approval, and the absence of project cost information. He calls on Port Commissioners and the FAA to extend the public comment period and subject the plan to greater independent scrutiny.

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.

The City of Tukwila submitted formal comments on December 13, 2024, objecting to SeaTac Airport's Sustainable Airport Master Plan Draft Environmental Assessment (SAMP Draft EA), arguing that the study area is too narrow, covering only 3,692 acres, and fails to account for broader impacts on surrounding communities including increased traffic, air quality degradation, and noise under flight paths. The city contends that proposed mitigation measures are inadequate and that the assessment ignores equity and social justice concerns affecting the low-income, diverse communities near the airport. Tukwila is calling for a full Environmental Impact Statement with an expanded General Study Area that includes the entire city and broader South King County region.
