    Homeowner handbook

    ★ 32
    The Port of Seattle's Homeowner Handbook is a guide for residents participating in the Sea-Tac Airport Noise Remedy Program, which provides sound insulation improvements to affected homes. It walks homeowners through a 14-step process covering everything from attending an initial briefing and scheduling an inventory audit, to overseeing contractor bidding, managing construction, and signing off on completed work. The handbook was prepared by the Port of Seattle Noise Remedy Staff and last revised in June 1997.

    Final Evaluation of Noise Abatement and Noise Remedy Measures – Acoustical Treatment of Existing Structures

    ★ 32
    This draft report from Peat Marwick, consultants to the Port of Seattle, evaluates noise remedy measures for neighborhoods surrounding Seattle-Tacoma International Airport. It outlines eligibility criteria for a sound insulation program, targeting approximately 5,529 existing residential structures exposed to noise levels of Ldn 70 or higher in 1980, or Ldn 65 or higher projected for the year 2000. The recommendations build on the 1976 Sea-Tac/Communities Plan, reflecting updated noise exposure data, airline deregulation impacts, and residential growth in the area.

    Jackson International Airport Noise Remedy Update Community Attitude Survey

    ★
    In November 1983, the Port of Seattle sent this letter and attached survey summary to attendees of neighborhood workshops held near Jackson International Airport (Sea-Tac), informing them of community attitude surveys conducted by McClure Research Company on aircraft noise concerns. The surveys gathered resident opinions on potential noise remedy programs—including purchase guarantees, noise insulation cost-sharing, and avigation easements—to help planners assess program feasibility and likely participation rates. Results showed that workshop attendees' concerns closely mirrored those of the broader affected community living in areas with noise levels of 70 Ldn and above.

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.
