    Property Acquisition Financial Feasibility Study

    This 1997 Puget Sound Regional Council study examines the financial feasibility of acquiring and redeveloping properties negatively affected by major regional transportation facilities, including Sea-Tac International Airport, the Auburn Rail Yard, and a proposed Everett HOV facility. It evaluates potential funding mechanisms—such as a state-financed revolving fund or public/private partnerships—to convert noise-impacted land within the 65–75 DNL noise contours to compatible non-residential uses. The study covers roughly 100 acres across three case-study areas and was initiated under Regional Council Resolution A-96-02 adopted in July 1996.

    PSRC Resolution A-96-02: amending the 1995 MTP and related planning documents to provide for the long-term commercial air transportation capacity needs of the Central Puget Sound Region

    In July 1996, the Puget Sound Regional Council adopted Resolution A-96-02, amending the region's Metropolitan Transportation Plan to include plans for a third runway at Seattle-Tacoma International Airport, paired with additional noise reduction measures. The decision followed years of study, including an Expert Panel finding that neither demand management strategies nor high-speed rail could eliminate the need for expanded capacity. Final approval of the runway remained contingent on environmental review by the Port of Seattle, Federal Aviation Administration permitting, and completion of required noise mitigation steps.

    Summary of the Regional Council’s decision process relating to amending the Metropolitan Transportation Plan to include a third runway at Sea-Tac International Airport with additional noise reduction measures

    This 1996 Puget Sound Regional Council document summarizes the multi-year planning process that led to amending the regional transportation plan to include a third runway at Seattle-Tacoma International Airport. It traces decisions from the 1988 Regional Airport System Plan through the Flight Plan Project and environmental studies, explaining how planners concluded that no feasible alternative airport site existed and that measures like high-speed rail or congestion pricing could not substitute for added runway capacity. The plan also required implementation of additional noise reduction measures as a condition of approving the new runway.

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.
