    Airport noise insulation project

    This October 2016 Port of Seattle briefing presents the Airport Noise Insulation Project for Sea-Tac Airport, outlining how a federally guided noise study (known as a Part 150) is used to identify noise and land-use conflicts in surrounding communities. The project aims to provide sound insulation to eligible homeowners in high-noise areas, with approved mitigation measures qualifying for 80% federal Airport Improvement Program (AIP) grant funding. The briefing covers project elements, homeowner eligibility requirements, community benefits, and associated costs.

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.
