    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.

    Declaration of Lawrence Corvari Supporting Plaintiff’s Petition for a Writ of Review

    In October 1998, Lawrence Corvari, Co-President of Citizens Against Seatac Expansion (CASE), filed a declaration in King County Superior Court supporting a petition for a writ of review against the Port of Seattle. The declaration states that CASE directed its attorneys to appeal the Port's SEPA Determination of Non-Significance (DNS) related to the Auburn Mitigation Project, arguing that the Port's failure to comply with environmental review requirements harmed both the organization's members and the Miller Creek Basin environment.

    Letter from A. Brown to City of Burien: Comments on South King County Impact Assistance and Mitigation Studies Team Draft

    A Normandy Park resident and aerospace engineering manager submitted detailed comments in November 1996 criticizing a draft impact study related to Sea-Tac Airport's proposed Third Runway, arguing that the analysis underestimated real estate value losses, air pollution risks, and traffic disruptions caused by the project. The letter contends that home values in Normandy Park stagnated or declined after the Third Runway was publicly announced, and that any valid property value assessment must use baseline figures from before negative publicity began. The author also challenges the study's air quality modeling assumptions and traffic analysis, warning that the Port of Seattle would selectively cite favorable findings while ignoring methodological flaws.

    CASE Group History and Third Runway Opposition Flyer and Petition

    The CASE Group (Citizens' Alternatives to Sea-Tac Expansion) was formed in 1987 to oppose the Port of Seattle's plans to add a third runway at Sea-Tac Airport, gathering over 4,600 protest signatures and prompting the King County Council to pass a resolution against the expansion. The coalition organized public hearings, lobbied Port Commissioners, and circulated petitions urging state officials to reject expansion recommendations in favor of building a new regional airport away from densely populated areas. Their core argument was that alternatives to Sea-Tac expansion represented sounder economic and environmental choices for the Central and South Puget Sound region.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

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.
