The cities of Burien, Des Moines, Normandy Park, and SeaTac have entered into a formal interlocal agreement to coordinate their review of, and potential legal challenges to, the Port of Seattle's Sustainable Airport Master Plan, which could bring significant growth and environmental impacts to their communities over the next 20 years.

This document outlines the federal (NEPA) and state (SEPA) environmental review processes related to Sea-Tac Airport, tracing key milestones from initial scoping in 2018 through the issuance of a Finding of No Significant Impact (FONSI) in September 2025 and a subsequent court appeal filed in November 2025.

Together, these timelines reflect years of coordinated efforts by multiple cities to formally challenge and scrutinize the environmental impacts of airport operations and expansion.
