    Letter from Virginia Dana Opposing Highline Communities Plan Soccer Fields Under Flight Path

    In this letter, resident Mrs. Virginia E. Dana strongly opposes plans to place soccer and football fields under the flight path near Sea-Tac Airport, arguing that the FAA's own density guidelines and safety recommendations are being ignored. She references a 1974 FAA letter stating that certain land uses would not be permitted in extended clear zones with FAA participation, and criticizes Highline planners for repeatedly siting recreational facilities in inappropriate locations near the airport. Dana urges officials to hold public meetings and transparently inform neighboring residents about the planning process, including FAA guidelines and maps.

Issues

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.
