    SeaTac Airport history

    Seattle-Tacoma International Airport (Sea-Tac) has grown from a modest wartime airfield dedicated in 1944 on 906 acres of land near Bow Lake into one of the busiest airports in the United States, now serving nearly 47 million passengers annually. Over the decades, the airport underwent numerous expansions, security upgrades, and name controversies while navigating major events such as airline deregulation, the post-9/11 security overhaul, and a community-opposed third runway completed in 2008. Today, Sea-Tac supports more than 87,000 jobs and generates over $22 billion in economic activity for the region.

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.
