    Water District reaches settlement agreement with Port Of Seattle

    In November 1999, Highline Water District and the Port of Seattle reached a settlement agreement resolving competing claims over two water rights near Seattle-Tacoma International Airport. Under the deal, the Port retained rights to Well #1 for uses including Des Moines Creek flow augmentation tied to the proposed third runway project, while the District secured rights to a replacement for Well #2 to continue providing drinking water to its 58,000 customers. The District emphasized that the agreement was strictly about protecting its water rights and service area, and that it took no official position on the controversial third runway expansion.

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.
