    Supplemental Declaration of Lawrence Corvari Supporting CASE’s Consolidated Opposition Brief

    In this 1998 court declaration, Lawrence Corvari, Co-President of Citizens Against SeaTac Expansion (CASE), challenges the Port of Seattle's Auburn Mitigation Plan and its environmental review determination. Corvari argues that building replacement wetlands in Auburn rather than near the affected Miller Creek or Des Moines Creek watersheds leaves adverse environmental impacts unmitigated, harming CASE members' ability to enjoy local wildlife and a healthy environment. The declaration also corrects what Corvari describes as misrepresentations of his deposition testimony by the Port's attorneys in their Motion to Dismiss for Lack of Standing.

    Declaration of Helen Kludt Supporting Plaintiff’s Petition for a Writ of Review

    Helen Kludt, a Normandy Park resident who has lived near Miller Creek since 1956, submitted this 1998 court declaration supporting a legal challenge against the Port of Seattle's plans to expand Sea-Tac Airport with a third runway. She argues that the Port's proposal to destroy wetlands in the Miller Creek Basin and offset environmental impacts through out-of-basin mitigation in Auburn is inadequate and violates the State Environmental Policy Act (SEPA). Kludt contends the expansion will harm her property value, degrade local wildlife habitat, and worsen flooding along Miller Creek.

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.
