    Report and recommendations re interim land acquisition, Sea-Tac International Airport

    In September 1973, the Port of Seattle outlined a plan to acquire approximately 610 residential properties and 75 acres of open land surrounding Sea-Tac International Airport to create expanded clear zones north and south of the runways. The total estimated property cost was $15.46 million, with the Port anticipating over $8 million in federal FAA assistance and covering the remainder from airport revenues between 1974 and 1977. Under the best-case scenario, actual land acquisition could not begin until after July 1, 1974, following required environmental impact statements, housing relocation plans, and a multi-month FAA review process.

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.
