    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.

    Sea-Tac International Airport impact mitigation study: Initial assessment and recommendations

    ★ 32
    This February 1997 report, prepared for five cities near Seattle-Tacoma International Airport along with the Highline School District and Highline Community Hospital, assesses the impacts of Sea-Tac Airport on surrounding communities and offers initial mitigation recommendations. Funded by a State of Washington grant, the study was conducted by Hellmuth, Obata + Kassabaum and Raytheon Infrastructure Services to address concerns such as noise and other community impacts. It represents an early collaborative effort by local jurisdictions to seek remedies and protections for residents and institutions affected by airport operations.

    Resolution No. 3212, as amended

    ★ 32
    Resolution No. 3212, adopted by the Port of Seattle in 1996, approved the construction of a new third runway at Seattle-Tacoma International Airport (Sea-Tac) to address growing air traffic demand and reduce delays caused by poor weather conditions. The resolution followed years of regional studies, environmental impact reviews, and public involvement, including findings that no feasible alternative airport sites existed in the four-county area. It also committed the Port to fulfilling additional noise reduction measures as required by Puget Sound Regional Council Resolution A-96-02.

    Resolution No. EB-94-01: A resolution of the Executive Board of the Puget Sound Regional Council, Seattle, Washington

    ★ 32
    In October 1994, the Puget Sound Regional Council's Executive Board formally approved moving forward with a third runway at Seattle-Tacoma International Airport, concluding that no feasible sites existed for a supplemental airport in the four-county region. The resolution affirmed that the third runway would meet regional air capacity needs through 2030, provided it satisfied noise and demand management conditions and passed environmental review. The Board also recommended that the State develop legislation to compensate communities impacted by essential public facilities and explore long-term transportation alternatives, including high-speed rail.

    The Airport Noise and Capacity Act of 1990 (“ANCA”)

    ★ 32
    The Airport Noise and Capacity Act of 1990 (ANCA) established a national framework for managing aviation noise, requiring the Secretary of Transportation to create a uniform noise policy that phases out louder Stage 2 aircraft and regulates restrictions on quieter Stage 3 aircraft. The law ensures that any local airport noise restrictions—such as limits on flight hours or aircraft operations—go through a formal federal review process to prevent inconsistent, patchwork rules that could disrupt the national air transportation system. Passenger facility fees collected at airports may be used to fund noise reduction efforts and increase airport capacity.

    Resolution No. 2943 – Updated Noise Remedy Program

    ★ 32
    Resolution No. 2943 was adopted by the Port Commission of the Port of Seattle to update the Noise Remedy Program for Sea-Tac International Airport, replacing the earlier noise remedy element from the 1976 Sea-Tac Communities Plan. The resolution authorizes property acquisition in high-noise areas, implementation of nine noise abatement measures, and a Demonstration Project (budgeted at up to $1 million) to test alternatives to acquisition such as noise insulation and transaction assistance for affected homeowners. Priority for remedies is given based on noise intensity, length of residency, and financial hardship, with annual progress reports required to guide ongoing program evaluation.

    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.
