    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.

    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 Regional Airport System Plan to address long-term commercial air transportation needs for the central Puget Sound region. The resolution established a dual-track 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 unless a viable supplemental site could eliminate that need. Key conditions attached to the third runway approval included independent evaluation of demand management programs and measurable noise reduction performance objectives, while small supplemental airports such as Paine Field were eliminated as preferred alternatives.

    Report on Legal Issues in Connection with the Proposed Expansion of Seattle-Tacoma International Airport

    This April 1993 confidential legal report, prepared by law firm Cutler & Stanfield for the Airport Communities Coalition, examines the legal issues surrounding the proposed expansion of Seattle-Tacoma International Airport, including the construction of a third runway. It reviews the powers and responsibilities of key governmental entities — including the FAA, the Port of Seattle, the Puget Sound Regional Council, and surrounding cities — in relation to airport planning, noise abatement, and environmental impacts. The report also assesses geographic and environmental conditions in the SEA area, covering noise-sensitive locations, wetlands, air quality, and other factors relevant to community opposition to the expansion.

    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.

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.
