EXH AR052455: Des Moines Way Nursery Mitigation Plan, Seattle-Tacoma International Airport Master Plan Update Improvements

Notes

Parametrix, Inc. prepared this Des Moines Way Nursery Mitigation Plan (AR 052455) for Port Of Seattle, Seattle-Tacoma International Airport, November 2001, project number 556-2912-001(03). The plan covers wetland restoration and enhancement at the Des Moines Way Nursery mitigation site, including grading design, expected hydrology, wildlife considerations, planting plan, vegetation monitoring, performance standards, maintenance and contingency plans, and construction sequencing for the Sea-Tac Airport Master Plan Update Improvements. Topics include wetland classification, upland vegetation, soils, invasive plant species control, erosion control seed mix, buffer mitigation areas, and a proposed implementation timeline.

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.
