Declaration of Joseph Brascher of Aqua Terra Consultants in PCHB case 01-133, Airport Communities Coalition (ACC) v. Department of Ecology and Port Of Seattle. Brascher describes his expertise in surface and groundwater modeling using HSPF, SWMM, MODFLOW, and other hydrologic software packages. Aqua Terra acted as subconsultant to Parametrix, Inc. for the Low Flow Analysis Flow Impact Offset Facility Proposal submitted to Washington State Department of Ecology in July 2001. Aqua Terra modeled surface water flows in Miller Creek and Walker Creek associated with Port Of Seattle Master Plan Update (MPU) construction at Seattle-Tacoma International Airport (STIA) using the Hydrologic Simulation Program – Fortran (HSPF) model. Parametrix modeled Des Moines Creek. Filed with Foster Pepper & Shefelman PLLC, case AR 012668–012670.

Sidebar On/Off

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.
