    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.

    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.

    Proposed Airport Advisory Committee (1st Draft)

    This 1st draft memo from Jay Holman proposes adding an Airport Advisory Committee provision to RCW Chapter 53.54 on aircraft noise abatement. The committee would consist of five citizens living within five miles of the airport, appointed by Port Commissioners from a list submitted by the county, and tasked with meeting monthly to review Port decisions, relay community concerns, and make noise abatement recommendations. Members would serve staggered five-year terms, with new appointments beginning annually in 1982.

    Letter to Port Of Seattle Commissioners supporting acquisition on 26th Ave. South

    In July 1984, homeowners on 26th Ave. South near Seattle-Tacoma International Airport wrote to Port of Seattle Commissioners supporting the acquisition of their properties under the Noise Remedy program, citing increasing aircraft noise, growing industrial traffic hazards, and uncertainty that had delayed home maintenance. A separate letter from the Port's Director of Aviation to an airline captain acknowledged that non-compliance with existing noise abatement procedures — such as aircraft flying lower or turning sooner than prescribed — was a significant community concern, and noted that the Port was developing computer software using FAA radar data to automatically detect and report such violations.

    Suggested transaction assistance process flow diagram: Neighborhood Reinforcement Program area, purchase assurance noise remedy option

    This April 1984 working draft outlines the Port of Seattle's suggested process for helping eligible homeowners near Sea-Tac International Airport sell their properties under the Neighborhood Reinforcement Program's Purchase Assurance Noise Remedy Option. Homeowners first list their homes on the market for a minimum of 90 days, and if unsold, may apply to the Port for transaction assistance, which can include a property appraisal, noise audit, mortgage subsidies, and partial real estate fee coverage. Depending on how the appraisal compares to the final listed price, the Port may acquire an avigation easement, assist with the sale, or ultimately purchase the property itself and market it for resale.

    Airport Noise Remedy Update–Jackson International Airport

    In February 1984, the Port of Seattle sent an update to concerned citizens about proposed noise remedy programs near Jackson International Airport (Sea-Tac), including land acquisition, purchase assurance, and sound insulation initiatives. A subcommittee recommended expanding the program boundaries to cover 275 additional residences under purchase assurance and 44 more under land acquisition, with criteria addressing airport-related development buffers and neighborhood continuity. The Port Commission was scheduled to review these recommendations at a Staff Review Session on February 28, 1984.

    Jackson International Airport noise remedy update: Overall program boundaries

    This 1984 draft document from the Port of Seattle outlines the Noise Remedy Update program for Seattle-Tacoma (Jackson) International Airport, defining geographic boundaries for three types of noise mitigation measures: property acquisition, purchase assurance, and sound insulation. The maps cover areas north through south of the airport, including neighborhoods such as Boulevard Park, Des Moines, Normandy Park, and Zenith, showing which zones qualify for each remedy based on aircraft noise exposure. Sound insulation coverage extends as far north as S. Kenyon Street, while acquisition zones are concentrated in the areas immediately surrounding the airport's runways.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

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.
