    Sea-Tac International Airport impact mitigation study: Initial assessment and recommendations

    ★ 32
    This February 1997 report, prepared for five cities near Seattle-Tacoma International Airport along with the Highline School District and Highline Community Hospital, assesses the impacts of Sea-Tac Airport on surrounding communities and offers initial mitigation recommendations. Funded by a State of Washington grant, the study was conducted by Hellmuth, Obata + Kassabaum and Raytheon Infrastructure Services to address concerns such as noise and other community impacts. It represents an early collaborative effort by local jurisdictions to seek remedies and protections for residents and institutions affected by airport operations.

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.
