    Seattle-Tacoma International Airport Part 150 Update: Commission Presentation

    The Port of Seattle is updating its Part 150 noise management plan for Seattle-Tacoma International Airport, which includes revising the official noise remedy boundary based on 2018 future noise contour projections. The updated boundary is generally smaller than the current one, reshaping which properties qualify for noise mitigation assistance. Continuing programs under the new boundary include sound insulation for both single-family homes and owner-occupied multi-family residences located within the affected area.

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.
