    Letter to airport-interested parties regarding Sea-Tac third runway reports

    A 1995 letter from the Regional Commission on Airport Affairs to airport-interested parties summarizes two reports submitted to an arbitration panel deciding the Sea-Tac Airport third runway issue. The reports argue that alternatives to the third runway—such as regional airport system use and peak-hour pricing—were not fairly considered, that flight delay figures cited to justify the runway were overstated, and that the project itself may never be buildable due to cost, financing, and construction obstacles. A separate shorter report addresses noise concerns related to the proposed runway.

    RCAA letter to Transportation Policy and Executive Board

    A January 28, 1993 letter from James T. Murphy of the Regional Commission on Airport Affairs (RCAA) to the Transportation Policy and Executive Board, presenting independent consultant research on air capacity options for the Puget Sound region. The letter notes that RCAA had delivered three volumes of material over three weeks, with a final compilation to follow, aimed at helping the Board make informed decisions about managing airport capacity. The RCAA, backed by dozens of community organizations and cities including Burien, Des Moines, Normandy Park, and Tukwila, framed its work as an alternative voice on Sea-Tac Airport expansion and noise policy.

    RCAA Regional Commission on Airport Affairs information packet

    The Regional Commission on Airport Affairs (RCAA) was a coalition of cities and citizen groups in the Puget Sound region that opposed the proposed third dependent runway at Seattle-Tacoma International Airport in the early 1990s. The organization compiled expert research and white papers covering noise impacts, public health effects, environmental and social consequences, and economic costs associated with airport expansion. Their goal was to identify financially feasible and environmentally responsible alternatives to meet the region's air capacity needs without further expanding Sea-Tac.

    RCAA presentation materials on demand management, airport planning, and system alternatives

    This January 1993 document from the Regional Commission on Airport Affairs (RCAA) presents materials to the Puget Sound Regional Council's Transportation Policy and Executive Board covering demand management, airport planning, and regional air capacity alternatives. The packet includes analysis of flight delays, airspace and runway capacity issues, and landside capacity concerns prepared by consultants J. Richard Aramburu and Gerald Bogan, along with alternative airport development ideas from locations such as Grays Harbor County, Toledo-Winlock, and Moses Lake. The RCAA, backed by dozens of community groups and several cities in the Sea-Tac area, sought to offer expert-driven solutions to address long-term aviation capacity needs while addressing aircraft noise concerns affecting surrounding neighborhoods.

    Regional Commission on Airport Affairs Book #1

    This is Book #1 of materials compiled by the Regional Commission on Airport Affairs (RCAA), a coalition of community organizations and cities in the Puget Sound region, submitted to the Transportation Policy Board in January 1993. The packet presents expert reports on air traffic forecasting, economic impacts, noise, effects on children's education, public health, and air pollution—all focused on the proposed expansion of Seattle-Tacoma (Sea-Tac) International Airport. The RCAA argues against airport expansion on the grounds of quality of life, environmental harm, and equity for surrounding communities.

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.
