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.Open full document
