    Fashion update: What Puget Sound will be wearing in the year 2000

    This brochure, published by the Regional Commission on Airport Affairs (RCAA), argues against the Port of Seattle's 'Flight Plan' proposal to add a third runway at Sea-Tac International Airport. It highlights existing noise burdens on South End communities—where jet noise already averages 65 Ldn and reaches up to 105 decibels—and warns that the expansion would add 120,000 more flights annually by 2020, consuming 12% of residents' daily lives with jet noise. The document cites health experts and a renowned noise specialist, Dr. James Chalupnik, to advocate for alternative solutions such as remote airports and high-speed rail instead of expanding the urban airport.

    500 million dollars? Guess the Port’s got money to burn.

    This pamphlet from the Regional Commission on Airport Affairs (RCAA) opposes a proposed third runway at Seattle-Tacoma International Airport, arguing that construction costs alone could exceed $500 million and balloon to $1.2 billion when mitigation and interest are included. Economists cited in the document warn that the true total cost could approach $2 billion when factoring in school insulation, declining property values, and other indirect impacts on surrounding communities. The RCAA contends that taxpayers and airline passengers would bear up to 92% of the cost while receiving a runway that generates less than 1% return on the public's investment.

    Documents catalogued as received in 1992

    This catalog lists documents received in 1992 related to aviation planning and noise policy in the Puget Sound region, with a focus on Sea-Tac International Airport (STIA). It includes environmental impact statements, noise exposure maps, community association comments, budget documents, and FAA regulatory guides, many connected to the 'Flight Plan Project' — a regional air transportation study. Several items were donated by attorney J. Richard Aramburu and other community stakeholders involved in airport noise and development issues.

    Summary of the Regional Council’s decision process relating to amending the Metropolitan Transportation Plan to include a third runway at Sea-Tac International Airport with additional noise reduction measures

    This 1996 Puget Sound Regional Council document summarizes the multi-year planning process that led to amending the regional transportation plan to include a third runway at Seattle-Tacoma International Airport. It traces decisions from the 1988 Regional Airport System Plan through the Flight Plan Project and environmental studies, explaining how planners concluded that no feasible alternative airport site existed and that measures like high-speed rail or congestion pricing could not substitute for added runway capacity. The plan also required implementation of additional noise reduction measures as a condition of approving the new runway.

    Resolution A-93-03: A resolution of the General Assembly of the Puget Sound Regional Council amending the 1988 Interim Regional Airport System Plan (RASP) for long-term commercial air transportation capacity needs of the region

    In April 1993, the Puget Sound Regional Council adopted Resolution A-93-03, amending its 1988 Regional Airport System Plan to address long-term commercial air transportation needs in the central Puget Sound region. The resolution established a preferred strategy of pursuing both a major supplemental airport within the four-county area and a third runway at Sea-Tac Airport, with the third runway to be authorized by April 1, 1996 subject to conditions including noise reduction performance objectives and demand management efforts. The resolution also eliminated small supplemental airports such as Paine Field as a preferred alternative and called for site-specific environmental impact studies on the proposed Sea-Tac third runway.

    PSAPCA’s role regarding airport air quality

    The Puget Sound Air Pollution Control Agency (PSAPCA) raised concerns in 1992 about inadequate air quality analysis in the Flight Plan Project's environmental impact statement, citing missing dispersion modeling for both vehicle and aircraft emissions near Sea-Tac Airport. A follow-up 1992 letter addressed the use of ethylene glycol as a de-icing agent at Sea-Tac, concluding it was unlikely to pose a significant air quality risk due to its low vapor pressure. A 1993 internal memo clarified PSAPCA's role in reviewing airport-related environmental impact statements and conducting annual inspections of registered equipment at airports within its jurisdiction.

    Flight Plan Project: Materials distributed at the Flight Plan workshops for the Regional Council’s Transportation Policy Board and Executive Board

    This collection contains materials from the Flight Plan Project workshops held in January and February 1993, organized for the Regional Council's Transportation Policy Board and Executive Board to address airport planning and capacity needs in the Puget Sound region. The binders include working papers, overhead presentations, environmental impact statement documents, public hearing records, and correspondence from stakeholders ranging from the FAA and Port of Seattle to community groups opposing airport expansion. Key topics covered include demand management, noise abatement, regional airport system alternatives, and the evaluation of sites such as Sea-Tac and Paine Field.

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.
