This Port of Seattle document explains flight track plots for Seattle-Tacoma International Airport, which are overhead graphic illustrations showing the ground paths of arriving and departing jet aircraft over a 24-hour period, separated into daytime and nighttime operations for both north and south traffic flows. The data is sourced from the FAA's Automated Radar Terminal System (ARTS). Notably, the document emphasizes that even aircraft following identical routes will not fly the exact same path, as factors like pilot technique, air traffic control, weather, and aircraft performance cause flight corridors to widen with increasing distance from the airport.

The Flight Plan Project, a joint effort by the Puget Sound Regional Council and the Port of Seattle, produced this 1992 Final Environmental Impact Statement to evaluate long-term commercial air transportation options for the central Puget Sound region. It examines system-level alternatives ranging from expanding Sea-Tac Airport to building new airport facilities, assessing trade-offs related to noise, air quality, land use, and regional quality of life. The document serves as a programmatic planning tool, with no single preferred alternative identified, intended to guide future site-specific environmental reviews and regional airport policy decisions.

A 1992 brochure from the Regional Commission on Airport Affairs (RCAA) argues that the Port of Seattle broke its 1973 promises to soundproof homes affected by Sea-Tac Airport noise, noting that only 700 of 10,000 impacted homes had been insulated and no public buildings had been treated despite a recognized obligation since 1988. The brochure opposes the Port's plan to spend up to $1.2 billion on a third runway at Sea-Tac, questioning how residents can trust new commitments when past ones went unfulfilled. It calls on the Port to fulfill its existing mitigation obligations before pursuing further airport expansion.

Port Of Seattle Commission Resolution No. 3119, adopted September 8, 1992, authorizing the Executive Director to execute an Interlocal Agreement between the City of SeaTac and the Port of Seattle for enforcement of the State Building Code at Seattle-Tacoma International Airport. The resolution references RCW Title 19 (1976), the Airport Building Department established in 1976

The CASE Group (Citizens' Alternatives to Sea-Tac Expansion) was formed in 1987 to oppose the Port of Seattle's plans to add a third runway at Sea-Tac Airport, gathering over 4,600 protest signatures and prompting the King County Council to pass a resolution against the expansion. The coalition organized public hearings, lobbied Port Commissioners, and circulated petitions urging state officials to reject expansion recommendations in favor of building a new regional airport away from densely populated areas. Their core argument was that alternatives to Sea-Tac expansion represented sounder economic and environmental choices for the Central and South Puget Sound region.

A 1992 water quality study of Des Moines Creek, prepared by Parametrix, Inc. for the FAA and Port of Seattle, assessed the health of the creek during storm runoff events. The creek, which originates near Sea-Tac International Airport and flows to Puget Sound, had its aquatic ecosystem severely damaged by jet fuel spills in 1985 and 1986. The study sampled seven locations along the creek and three tributaries to identify water quality problems and determine whether stormwater pollution from airport operations was causing toxic conditions.

AR037747. Draft Final Report of the Puget Sound Air Transportation Committee’s Flight Plan Project, January 1992, sponsored by the Puget Sound Regional Council and Port Of Seattle with FAA grants. Study findings and draft recommendations for long-term air carrier system needs of the Puget Sound Region, including a Draft Programmatic Environmental Impact Statement. Committee chaired

In 1991, the Puget Sound Air Transportation Committee (PSATC) gathered public input on long-term air capacity solutions for the Seattle region, with over 1,200 people participating through meetings and written comments. Key public concerns included opposition to expanding Sea-Tac Airport, worries about noise and air pollution impacts on nearby residents, and support for high-speed rail alternatives. The committee identified several potentially feasible options—including multiple airport systems and a new international airport to replace Sea-Tac—while ruling out others, such as a distant remote airport and high-speed rail alone, as insufficient stand-alone solutions.
