    Final Staff Evaluation for SEPA Environmental Checklist – Des Moines Creek Basin Restoration Projects

    ★
    The City of SeaTac conducted an environmental review of the Des Moines Creek Basin Restoration Projects, a multi-agency effort involving the cities of SeaTac and Des Moines, the Port of Seattle, and King County. The project aims to improve water quality, reduce flooding, and restore fish habitat along Des Moines Creek by building a new detention facility, installing a high-flow bypass pipe, and maintaining low-flow water levels during dry summer months. The city's staff determined that the project does not require a full Environmental Impact Statement, as it is not expected to have a significant adverse impact on the environment.

    Joint letter from Burien, Des Moines, and SeaTac requesting extension of SAMP SEPA DEIS comment period

    In July 2026, the city managers of Burien, Des Moines, and SeaTac jointly wrote to Port of Seattle Commissioners demanding that the public comment period for the Sustainable Airport Master Plan's Draft Environmental Impact Statement be extended from 60 to at least 120 days. The cities argued that the document's enormous size (over 6,000 pages), technical complexity, and missing underlying data made meaningful review within 60 days impossible, particularly for lower-resource community members most affected by airport impacts. The letter also called on the Port to honor its own equity commitments by ensuring historically overburdened communities surrounding the airport have a genuine opportunity to participate in the review process.

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. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
