    A set of daily tracks from March 1 to March 18, 2018, giving a representation of North Flow and South Flow departure and arrivals. To make sense of these we suggest reading our article on runways and flow. People who complain about the flight concentration immediately notice the pattern to ‘the funnel’, ie. the points

  • SAMP For Dummies

    The Sustainable Airport Master Plan (SAMP) is the blueprint for increasing flight capacity by one third in the next ten years. It will have the same community impact as the Third Runway. In fact, it is happening now. How this is possible, and what it means for us.

    Why electric airplanes are no panacea

    The (very) good news is that there is more than one zero-emission aviation technology coming. But at the risk of being Mr. Negative, at least for airport communities, electric airplanes are no panacea. And we say that not to inspire despair but to tell residents the realities, which are: Each of these alternatives comes with

  • Are the airplanes getting louder and lower?

    No. And maybe. Objectively speaking, individual aircraft flyovers near Sea-Tac Airport are not getting lower or louder. (Before you click away in disgust, note that some of our members live as low as ‘760’, ie. when correcting for sea level less than 400 feet directly under the belly of an aircraft. No one is more

  • So you want to be a Port Commissioner?

    The purpose of this explainer is is sort of a handy one-pager for candidates for a seat on the Port Commission.

  • Who decides what happens at Sea-Tac Airport?

    If you’re trying to get some relief from all the flights, you probably will have some questions like, “Who do I blame?” And it gets confusing because there are three entities that share responsibility for everything that goes on at Sea-Tac Airport: the FAA, The Port Of Seattle, and the airlines.

  • Why Can’t We Have A Curfew?

    Blame it on ANCA , the Airport Noise And Capacity Act Of 1990. Airport law–specifically the history of how communities lost their rights–is long.

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.
