    Request for 90-day extension to SAMP SEPA draft EIS comment period

    The cities of SeaTac, Burien, and Des Moines jointly wrote to the Port of Seattle on May 18, 2026, requesting a 90-day public comment period for the Sustainable Airport Master Plan (SAMP) Draft Environmental Impact Statement.
