Presentation by David Goebel (nornp.org) delivered November 5, 2017, addressing the noise impact of the FAA’s NextGen program on Vashon Island. Topics include airport flow fundamentals explaining why Sea-Tac Airport arrivals overfly Vashon Island despite north/south runway orientation, Southflow vs. Northflow statistics, conventional RADAR STAR procedures versus the new NextGen HAWKZ RNAV approach, intended and actual altitude outcomes of the procedure change, real-time flight path resources, and actions taken by other communities. Also references the Schultz Curve on community noise response and behavioral consequences of environmental noise exposure.

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.
