    Highline Communities

    Where Did the Term “Highline Communities” Come From? Today, the phrase “Highline Communities” is frequently used to describe the cities and neighborhoods surrounding Seattle-Tacoma International Airport. The term appears in airport planning documents, environmental reports, and regional government discussions. But where did it come from? It turns out the name predates Sea-Tac Airport by decades.

    Exhibit 16: Highline Communities Plan — Legal and Administrative Framework, Committee Members, and Forward Thrust Fund Reallocation Request (1976–1977)

    This document contains materials from the 1977 Highline Communities Plan, outlining the legal and administrative framework governing the Highline area near Sea-Tac Airport in King County, Washington. It references key planning documents including the 1964 King County Comprehensive Plan and the 1976 Sea-Tac Communities Plan, which sought to balance airport operations with surrounding residential communities through noise mitigation measures such as property acquisition, insulation programs, and land use controls. A 1976 memo from the Highline Communities Plan Committee also requests that Forward Thrust funds not be reallocated until the Highline Communities Plan was formally adopted.

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.
