    Aerial View of Stormwater Detention Pond Under Construction Near Sea-Tac Airport

    Aerial photograph showing a large engineered stormwater or detention pond under active construction adjacent to what appears to be Sea-Tac Airport, with a runway, terminal buildings, and aircraft visible in the background. Construction equipment, temporary structures, and disturbed soils are visible around the pond perimeter, suggesting this documents infrastructure development in the airport vicinity.

    Sea-Tac Airport Aerial View Showing Runways, Terminal, and Puget Sound

    Aerial photograph showing Sea-Tac Airport's runway complex, terminal area, and cargo/maintenance facilities, with a large surface parking lot in the foreground and Puget Sound visible in the background. The image appears to date from the late 1970s or 1980s based on vehicle styles and airport infrastructure visible.

    Aerial View of Construction and Retention Pond Adjacent to Sea-Tac Airport Runway

    Aerial photograph showing active construction activity adjacent to an airport runway, featuring a large retention or detention pond with sandy berms, a flat-roofed structure under development, road infrastructure with a tunnel underpass, and commercial/parking areas in the foreground. The proximity to runway markings and airport taxiway infrastructure is consistent with Sea-Tac Airport environs.

    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.

    R.C.A.A. catalog of issues papers & critiques

    This December 1992 catalog from R.C.A.A. (Residents for Conscious Airport Activity) lists research papers, critiques, and white papers organized by topic—including airport planning, demand and capacity, economics, health, environmental impacts, and noise—all relating to Sea-Tac International Airport expansion. Key concerns addressed include aircraft noise measurement and the adequacy of the 65 Ldn noise metric, air and water pollution from airport expansion, and the evaluation of alternative airport sites. The catalog reflects community and expert opposition to Sea-Tac's third runway proposal and broader regional airport policy decisions in the Puget Sound area.

    WARNING: ‘Flight Plan’ could be hazardous to your health

    A 1992 pamphlet published by the Regional Commission on Airport Affairs (RCAA) warns that the Port of Seattle's expansion plan for Sea-Tac Airport — including the addition of a third runway — poses serious health risks to surrounding communities. Citing studies reviewed by physicians at Highline Community Hospital, the brochure links increased airport activity to higher rates of birth defects, cardiovascular disease, mental illness, and dangerous levels of air pollutants such as carbon monoxide, benzene, and lead. The document concludes that when health and community costs are fully considered, Sea-Tac expansion may be neither financially feasible nor ethically justifiable.

    The adverse health impacts of airport expansion with particular reference to Sea-Tac International Airport

    A 1992 report by physicians from the Regional Coalition on Airport Affairs details the serious health risks posed by Sea-Tac International Airport's noise and air pollution on surrounding communities. It documents links between airport noise and increased use of tranquilizers, psychiatric hospitalizations, sleep disruption, lower birth weights, and declining school test scores, while also noting that Sea-Tac generates up to 5% of all air pollution in King County. The report argues that airport expansion would significantly worsen these already measurable public health impacts on South King County residents.

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.
