  • SR-509 south access road is a rumor-Screenshot 2023-01-17 at 13-54-13 Des Moines Community Group Facebook

    A Facebook comment thread in which user 'JC Harris CMDM' states that a southern entrance to Seattle-Tacoma International Airport (SEA) has been part of the airport's long-term strategic goals since at least 1976, attributing delays to FAA/EPA environmental review of the SAMP. A second commenter disputes the claim, and Harris pushes back, asking the commenter to clarify who they mean by 'our' and asserting it is not a rumour.

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.

The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
