    King County Council Notice: Proposed Motion 81-322 Rescinding Motion 4668, Building and Land Development File 224-78-R (Port Of Seattle Reclassification)

    ★ 32
    In December 1979, the King County Council passed Motion 4668 approving a rezone request by the Port of Seattle (Building and Land Development File No. 224-78-R), subject to conditions including the Port providing 5 acres for a neighborhood park and agreeing not to develop a 55-acre Westside Greenbelt buffer area for ten years. In May 1981, the Council proposed Motion 81-322 to rescind and replace Motion 4668, with key differences in the conditions outlined on page 2 of each motion. The matter, which had been appealed by both the applicant and neighboring property owners, required a separate public hearing in affected communities as part of the site plan approval process.

    Sea-Tac Communities Plan background and environmental findings

    This document summarizes the Sea-Tac Communities Plan, a 1973 joint study by the Port of Seattle and King County to improve compatibility between Sea-Tac International Airport and its surrounding neighborhoods. The plan examined aircraft noise exposure, air and water quality, and community growth, finding that noise levels were expected to decrease over time due to quieter aircraft technology despite rising flight operations. It proposed a range of noise remedy programs—including property acquisition, purchase guarantees, and insulation assistance—affecting thousands of homes in areas north and south of the airport.

    Highline on way to decentralization

    The Highline area may become an experiment in decentralized county government services, with County Executive John Spellman recommending the use of existing buildings throughout King County as community service centers rather than constructing new mini-courthouses. The initiative, backed by a study from the County Department of Community and Environmental Development, aims to improve government responsiveness by bringing county services such as parks, assessor, and other offices closer to residents. A surplus school building in the Hamlin Park-Firlands area has been suggested as a potential site for a new north precinct police station.

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.
