    Toledo-Winlock area visitation

    A September 1992 internal memo from Doug Graves and Len Oebser to Rick Aramburu summarizes a site visit to the Toledo-Winlock area of Washington State as a potential location for a new replacement airport. The site was praised for its large size, proximity to the I-5 freeway midway between Seattle and Portland, access to Burlington Northern rail lines, and its sparsely populated surroundings, which would minimize noise and environmental impacts. However, drawbacks noted included its distance from major population centers such as Seattle, Tacoma, Everett, and Portland, which would require some form of mass rapid transit to serve the airport effectively.

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.
