The Joint Des Moines and Burien Airport Committee is scheduled to meet on June 8, 2026, at 4:00 PM in the Des Moines City Council Chambers to hold a study session on the Sustainable Airport Master Plan (SAMP), with reference materials available at sea-samp.com/materials. The SAMP is a planning process relevant to Sea-Tac Airport's future development and its noise and environmental impacts on surrounding communities. The next scheduled meeting is the Des Moines Airport Advisory Committee Meeting on July 13, 2026.

The City of Des Moines, WA provided its City Council with an update on the Sustainable Airport Master Plan (SAMP) for Seattle-Tacoma International Airport, following the FAA's September 2025 approval of 31 near-term expansion projects — including 19 new gates, a second terminal, and cargo facilities. The Port of Seattle launched a state-level environmental review (SEPA) in May 2026, releasing a Draft Environmental Impact Statement with a 60-day public comment period. Des Moines is collaborating with the cities of Burien and SeaTac through an Interlocal Agreement to submit coordinated comments, with the final report expected in 2027.

The mayors of Burien, Des Moines, and SeaTac jointly wrote to Port of Seattle Commissioners in 2026 to challenge the claim that airport expansion projects outlined in the Sustainable Airport Master Plan (SAMP) would have no significant impact on neighboring communities. The letter highlights concerns about aircraft noise, air pollution, traffic, and disproportionate burdens on historically disadvantaged residents living closest to the airport. The cities also demand that the public comment period for the Draft Environmental Impact Statement be extended from 60 to at least 120 days to allow for meaningful community review.
