    A letter I received this morning from Port Commissioner Fred Felleman in reply to my letter to the Port Commissioners yesterday. >JC — if the legislators want independence from the Port, they don’t have to take its recommendations.

    Avigation Easement

    This Avigation Easement is a legal agreement in which a homeowner near Seattle-Tacoma International Airport grants the Port of Seattle permanent rights to use the airspace above their property for all types of aircraft, without restriction on frequency or proximity. In exchange, the Port assists with noise-reduction modifications to the home, and the homeowner waives all current and future claims for noise-related damages. The easement runs with the land permanently, binding all future owners of the property to the same terms.

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.
