    Letter from King County Councilman Bob Grieve on Boeing HQ Relocation and Highline Community Plan

    King County Councilman Bob Greive wrote to constituents expressing his opposition to the relocation of Boeing's headquarters into an open space buffer zone near Sea-Tac Airport, an area designated under the 1977 Highline Community Plan to protect nearby residents from airport-related impacts. Despite his protests, the King County Council voted to amend the comprehensive plan and rezone the land from single-family residential to light manufacturing, with only three of nine council members opposing the measure. Greive vowed to continue fighting airport development that threatened surrounding neighborhoods and asked residents for their input on how to hold the Port Commission, federal government, and King County accountable to their promises regarding Sea-Tac.

    Highline Community Plan

    The Highline Community Plan, published by the King County Planning Division in November 1977, outlines land use policies and development guidelines for the Highline communities in unincorporated King County near Seattle. The plan addresses topics including development limitations, drainage and pollution, neighborhood stability, transportation, and parks and recreation. It was developed through a structured community planning process under the King County Department of Planning and Community Development.

    Substitute ordinance establishing Airport Open Use (AOU) zoning classification

    Ordinance 77-106, introduced in March 1977, established the Airport Open Use (AOU) zoning classification for areas around major airports like Sea-Tac, allowing compatible economic activities such as agriculture, public parks, commercial recreation, and public utility facilities while protecting neighboring residential areas. The ordinance sets strict conditions on signage, building setbacks, landscaping buffers, and livestock density to minimize conflicts with adjacent residential zones. Uses like golf courses, outdoor storage, and cemeteries require conditional use permits when the property borders residential (R or S) zones.

    Port of Seattle response to Virginia Dana regarding home relocation boundaries

    In March 1976, Virginia Dana wrote to Donald G. Shay, Director of Aviation at Sea-Tac International Airport, questioning why the Port of Seattle had not updated its relocation boundaries for airport-acquired homes to reflect new high-noise zones identified in the Sea-Tac Communities Plan. She argued that using Highway 99 as an eastern boundary was inadequate and that vacant lots east of the airport, between the airport and South 126th, could accommodate relocated homes while boosting the local tax base. Shay responded that the Port would review her suggestion and consider whether to revise its existing relocation directives.

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.
