This document contains official corrections and modifications to the Highline Communities Plan, a land-use planning document for communities near Sea-Tac Airport in King County, Washington. It addresses errata such as street name corrections, zoning designation changes, and map updates, as well as adopted modifications related to hazard area development, Planned Unit Developments (PUDs), and a notable recognition of Boeing's proposed corporate headquarters on Port of Seattle property west of Sea-Tac Airport. The modifications also acknowledge that an environmental impact statement was being prepared by King County regarding the Boeing proposal, while community input had not yet been formally gathered.

228-78-R

In December 1979, the King County Council passed Motion No. 4668, concurring with the Zoning and Subdivision Examiner's recommendation to approve a land reclassification petitioned by the Port of Seattle (File No. 224-78-R), related to development of a Boeing facility near Sea-Tac Airport. As conditions of approval, the Port of Seattle was required to provide 5 acres for a neighborhood park along 12th Avenue South and to enter into a memorandum of understanding with King County freezing development on a 55-acre Westside Greenbelt buffer zone for ten years. The motion also mandated a separate public hearing in affected communities during the site plan approval process, reflecting efforts to balance airport-related development with residential stability concerns.

This 1979 environmental assessment from King County's Department of Planning & Community Development evaluates the Port of Seattle's application to rezone approximately five acres near Sea-Tac Airport to allow Boeing to build a corporate headquarters facility, including offices, parking, and a heliport. The proposed Phase I development would include a two-story building with roughly 95,000 square feet of office space and parking for 235 cars, with approximately 200 employees on site. The document also outlines the county's land use history and ordinances governing development on the west side of Sea-Tac Airport, emphasizing protections for adjacent residential neighborhoods.

King County notice of public hearing for Port of Seattle’s application to rezone 29.42 acres on 12th Avenue South from RS-7200 to RM-900-P for Boeing Company corporate headquarters. The hearing was scheduled for February 8, 1979.

This brochure from the Greater Highline Community Parks Board outlines the Master Plan for North Sea-Tac Park, a 50-acre recreational area developed in the airport's north clear zone — land set aside due to aircraft noise impacts. Formed after a 1979 jointly funded planning effort by the Port of Seattle and King County, the nonprofit board manages the park and the Sunset Activity Center (a former junior high school), offering facilities for groups such as a BMX club, equestrian association, and Kennedy High School cross-country trails. The document also promotes a Booster Club membership drive to support continued park development and operations.
