    EXH AR037723: Puget Sound Regional Council Resolution A-93-03 Amending the 1988 Interim Regional Airport System Plan (RASP)

    Resolution A-93-03 adopted by the Puget Sound Regional Council General Assembly on April 29, 1993, amending the 1988 Interim Regional Airport System Plan (RASP) for long-term commercial air transportation capacity needs of the central Puget Sound region (King, Kitsap, Pierce, Snohomish counties). Establishes as preferred alternative a major supplemental airport in the four-county area plus

    ACC Strategy Options and Recommendations Memorandum by Cutler & Stanfield

    A 1993 confidential legal memorandum from law firm Cutler & Stanfield to the Airport Communities Coalition (ACC) outlines strategies for opposing the planned third runway expansion at Seattle-Tacoma International Airport. The memo recommends that the ACC Cities prioritize preventing new runway construction as their primary goal, with secondary goals focused on reducing noise impacts, limiting night flights, and improving mitigation for affected residents. The overarching strategy was to build enough political and legal leverage so that airport expansion decisions could not practically move forward without the ACC Cities' participation.

    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.

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.
