    Aircraft noise environment and land use issues near Sea-Tac Airport

    This document outlines several key challenges related to aircraft noise near Seattle-Tacoma (Sea-Tac) Airport. It notes that existing noise measurement systems lack the precision needed by planners, residents, and courts, while federal FAA funds cannot be used to purchase noise-affected lands unless they serve specific airport purposes. Additional concerns include restricted HUD/VA mortgage financing in high-noise areas, the potential negative impact on local tax bases if the Port of Seattle acquires large amounts of noise-sensitive land, and widespread property owner anxiety over declining home values and marketability.

    A Property Value Study for King County and Port Affected Areas

    A property value study prepared by Saundra Mock of John L. Scott Real Estate examines how home values in King County and areas affected by Sea-Tac Airport air traffic compare to surrounding communities without an air traffic freeway overhead. Using data from the Northwest Multiple Listing Service, the study presents maps, zip codes, and median home values for affected and unaffected cities in the Seattle area, allowing readers to draw their own conclusions about the impact of airport noise on local real estate.

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.
