    Ep #40 Thank you, Explorer!

    What if the solution to decades of airport noise and community impacts has been hiding in plain sight all along? In this open letter to city managers across airport communities, we revisit a landmark yet largely forgotten document: the Sea-Tac Communities Plan of 1976. Built on the Port of Seattle's promise — *"As we do better, you'll do better"* — this collaborative plan was supposed to be the long-term answer for neighborhoods living under the flight path. So why has it been reduced to little more than an expensive property buyout program? The answer reveals a critical gap that neither elected officials nor community advocates can fill alone. Real, lasting solutions require sustained professional commitment to airport community planning — something that should have been established 50 years ago. If you work in city management, this episode speaks directly to you and the unique role only you can play in finally delivering on that broken promise.

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.
