    Highline Community Plan: Proposed Area Zoning

    ★
    This January 1980 King County Division of Planning report proposes new zoning maps for the Highline community, located south of Seattle between I-5 and Puget Sound, to implement the Highline Communities Plan adopted in December 1977. The plan translates land use policies into specific zoning classifications covering topics such as mixed-use development, mobile home development, an Airport Open Use Zone, and landscaping guidelines. It applies only to unincorporated King County areas and was subject to public community meetings and hearings before adoption by the County Council.

    Highline Communities Plan: Errata and Adopted HCP Modifications

    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.

    HCP Draft EIS Maps: Land Affected by Proposed Area Zoning and Proposed Changes in Residential and Nonresidential Zones

    These three maps outline proposed area zoning changes in communities surrounding Seattle-Tacoma International Airport, including White Center, Burien, and nearby neighborhoods. The plans identify land targeted for rezoning across residential categories (such as downzoning to single-family or upzoning to multi-family) as well as nonresidential categories (including airport open use, manufacturing, commercial, and air terminal-related business). Dotted boundaries mark primary impact areas around the airport, reflecting efforts to align land use policy with airport noise and operational concerns.

    Highline Communities Plan: Final Environmental Impact Statement

    The Highline Communities Plan (HCP) is a King County land use and zoning proposal covering the area between Puget Sound and Interstate 5, from the City of Seattle south to South 252nd Street, including Des Moines and Normandy Park. Prepared by the King County Department of Planning and Community Development and issued in draft form in April 1977, the plan was intended to guide land use policy, area zoning, capital improvements, and housing programs for the Highline Communities Planning Area. Upon adoption, it became the official county policy framework for this coastal suburban region located adjacent to what is now Sea-Tac Airport.

    Highline Communities EIS Draft

    The Highline Communities EIS Draft, prepared by King County Department of Planning and Community Development in 1977, proposes the adoption of a Community Plan and Area Zoning for the Highline area southwest of Seattle. The plan is intended to guide land use, capital improvements, housing, and utilities policy for communities including Burien, White Center, Des Moines, and Normandy Park. Upon adoption, it would become an element of the King County Comprehensive Plan, with expected benefits including pollution control, improved transportation, and economic stability for the region.

    Highline Communities Plan: Goals, Objectives, Policies

    The Highline Communities Plan (1976) is a King County planning document that builds on the Sea-Tac Communities Plan to improve neighborhoods surrounding Sea-Tac Airport. It establishes goals, policies, and implementation actions covering drainage, pollution, natural resource protection, and land use to support communities that are to be maintained rather than acquired or redeveloped due to airport noise impacts. The plan outlines specific measures such as sanitary sewering, surface water management, and open space preservation to achieve a quality living environment in the Highline area.

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.
