    Bird watching

    Our last post on funding Port Package updates (Three Votes. Three Dollars.) got many more letters than most. The reactions were everything from enthusiasm to sarcasm and in this year of the SAMP we think it’s time for a reality check. We recently picked up a new volunteer. That in itself is unusual these days.

    Three votes. Three dollars.

    Funding Port Package updates made simple There’s always been confusion about Port Packages (sound insulation): Who pays for it? Who can pay for it? Who is eligible? Who should be eligible? There are a bunch of rules governing all of the above. They may seem complicated. Because they are. But the actual solutions are simple.

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.
