    Appendix H: Land Use Technical Report — Sustainable Airport Master Plan Near-Term Projects

    This January 2024 Land Use Technical Report, prepared by Landrum & Brown for the Port of Seattle, examines how near-term construction projects at Seattle-Tacoma International Airport align with local and regional land use plans. It reviews existing and planned land uses in surrounding cities—including SeaTac, Des Moines, Burien, and Tukwila—and evaluates the potential land use impacts of proposed action alternatives. The report draws on key planning documents such as a 2018 Interlocal Agreement and the Puget Sound Regional Council's Vision 2050 to assess consistency with community goals.

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.
