    Your 2¢ Worth, Meeting #6: Alternative Futures

    This document records community feedback from Meeting #6 of a public engagement series on alternative futures for neighborhoods near Sea-Tac Airport, where residents from Valley View, Riverton Heights, Des Moines, and other areas discussed three options: creating greenbelts and open spaces, pursuing a planned city renewal approach, or allowing an unrestricted free market. Participants raised concerns about airport noise, property taxes, displacement of residents, loss of natural resources, and the Port of Seattle's land acquisition practices. Communities generally favored enforceable planning with citizen input, and many preferred the greenbelt option, while expressing skepticism about government-led redevelopment and unregulated market approaches.

Read This!

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.
