    Four cities near Sea-Tac Airport — Burien, Des Moines, Normandy Park, and SeaTac — have joined together under a formal interlocal agreement to coordinate their review of the Port of Seattle's Sustainable Airport Master Plan (SAMP), which could bring significant noise and environmental impacts to surrounding communities over the next 20 years. The agreement establishes a shared process for hiring consultants, submitting joint public comments, and responding to environmental documents produced under federal (NEPA) and state (SEPA) law. The collaboration is set to run through December 31, 2027, with the City of Des Moines managing consultant contracts and the City of Burien overseeing fiscal matters.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation.
