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.

The cities of Burien, Des Moines, Normandy Park, and SeaTac are renewing a cooperative agreement to jointly review and respond to the Port of Seattle's Sea-Tac Airport Sustainable Airport Master Plan (SAMP), which outlines future airport growth that could significantly impact neighboring communities. The new Interlocal Agreement (ILA), approved by Des Moines City Council in December 2024, extends collaboration through December 31, 2027, allowing the cities to share consultants and coordinate formal comments on the airport's environmental review process under NEPA and SEPA. Des Moines has committed up to $74,170 toward consultant services, with each city's share determined by relative population.

The Port of Seattle held a public meeting on December 3, 2024 in Des Moines, WA to present highlights from the Environmental Assessment (EA) for Seattle-Tacoma International Airport's Sustainable Airport Master Plan (SAMP). The SAMP outlines a wide range of near-term construction and expansion projects across the airport, including airside, landside, terminal, cargo, and support facilities. The meeting provided an opportunity for community members to learn about the plan's environmental findings and submit public comments.

The City of Des Moines, WA is purchasing $124,191 worth of Bird-X bird deterrent balls to cover a 32,000-square-foot stormwater detention pond at the Des Moines Creek Business Park, after the Port of Seattle notified the city in 2023 that the pond was out of compliance with FAA wildlife hazard standards. FAA Advisory Circular 150/5200-33C requires physical barriers on stormwater ponds near public-use airports—such as Seattle-Tacoma International Airport—when standing water persists longer than 48 hours and poses a risk of attracting hazardous wildlife that could interact with aircraft. The City Council approved the purchase on November 21, 2024, with costs funded through the Surface Water Management Maintenance Fund.

The Port of Seattle Commission approved its 2025 budget and five-year Capital Improvement Plan on November 19, 2024, outlining $1.1 billion in operating revenues and $678 million in operating expenses, alongside a $5.6 billion capital investment plan through 2029. The plan prioritizes infrastructure upgrades at Seattle-Tacoma International Airport (SEA), maritime facilities, and sustainability initiatives including waterfront electrification and alternative fuels. Additional commitments include community equity programs, workforce development, and efforts to reduce environmental impacts on surrounding communities.
