TagSea-Tac Communities Plan(215)

The Sea-Tac Communities Plan was a joint initiative launched in 1973 by the Port of Seattle and King County, funded in part by the FAA, to address conflicts between Sea-Tac International Airport operations and surrounding neighborhoods—particularly concerns about aircraft noise, property values, and land use. The plan found that while no major airport expansion was needed, noise remained a significant problem requiring a comprehensive remedy program including property acquisition, noise insulation, and purchase guarantees. Key recommendations called for coordinated action by the Port, County, and federal agencies to improve airport-community compatibility over a 20-year planning horizon.

The Sea-Tac Communities Plan was a federally funded, eighteen-month study sponsored by King County and the Port of Seattle to assess noise, air, and water quality impacts from Sea-Tac Airport and develop an airport master plan and land-use/zoning plan for surrounding neighborhoods. The Environmental Development Commission invited residents, community clubs, and local interest groups to participate in initial public meetings held at Highline and Thomas Jefferson High Schools in March. A central goal of the plan was to maximize citizen involvement in both the development and implementation of policies shaping the future of Sea-Tac Airport and its neighboring communities.

This document lists the published reports produced as part of the Sea-Tac Airport and Vicinity Master Plan study, a collaborative effort by King County, the Port of Seattle, consultants, and community members. The reports cover a wide range of topics including aviation demand forecasting, air and water quality analysis, solid waste, and noise exposure analysis across multiple volumes. Copies of these references were made available at the King County Land Use Management Division and the Port of Seattle Planning and Research Department.

This document, Part 7 (Implementation), Chapter 7.1, covers common problems and opportunities related to airport development, with a focus on the financial framework governing the Port of Seattle. It explains that the five-member Port of Seattle Commission is legally authorized to levy taxes on property within King County and to issue general obligation bonds, subject to strict limits—bonds cannot exceed 3/4 of 1% of the actual taxable property value in the district. Voter approval by 60% is required for bond issuances that go beyond the non-voter-authorized debt ceiling.

This document provides historical background on Seattle-Tacoma (Sea-Tac) Airport, tracing its origins to 1942 when the Civil Aeronautics Administration selected a site near Bow Lake and the Port of Seattle acquired the original 906 acres. As the jet age arrived and the airline industry expanded, the surrounding communities experienced rapid urbanization, bringing with it land use conflicts, traffic problems, pollution, and shortsighted commercial development. The Sea-Tac Communities Plan background chapter examines these challenges as context for developing more thoughtful, long-term planning policies for the airport region.

This document outlines the official significance and structure of a comprehensive land use and community planning report for Sea-Tac International Airport and its surrounding communities, jointly produced by the Port of Seattle and King County. It serves as the primary guide for official decisions on land use, capital expenditures, and public and private development review. The report is organized into eight parts covering plans, policies, programs, background information, and implementation strategies.

The Sea-Tac Communities Plan, sponsored by the Port of Seattle and King County, maps the West Reinforcement Area surrounding Seattle-Tacoma International Airport, identifying neighborhoods such as Hazel Valley, Chelsea, Seahurst, Gregory Heights, Sunny Terrace, and Blakley Manor that are affected by aircraft noise. The map highlights the Burien Center commercial core, grid cells where program eligibility is determined by noise criteria alone, and features such as streams, ponds, and heavy vegetation. It distinguishes between single-family residential structures and other buildings to guide noise mitigation and land-use planning efforts in the impacted communities.
