This document describes the planning study area surrounding Seattle-Tacoma (Sea-Tac) Airport, which encompassed the entire Highline School District and portions of the Federal Way and South Central School Districts. The study identified four sub-areas forming an 'airport vicinity' zone — defined as the area of primary airport-community incompatibility — to guide policy and land-use planning. King County holds major planning responsibility for the broader sub-regional area, with the Sea-Tac Communities Plan intended to integrate with the wider Highline Community Plan through post-plan coordination.

This document summarizes community responses to a questionnaire distributed as part of the Sea-Tac Communities Plan, asking residents near Seattle-Tacoma International Airport about preferred noise mitigation strategies. Respondents most commonly favored acquiring and removing existing buildings for noise-compatible uses, purchase guarantees for residential properties, and other locally-suggested ideas. The survey also captured opinions on open space use, environmental controls, and neighborhood improvement priorities such as greenbelts, parks, and street improvements.

This document is a formal response to public comments on the Sea-Tac/Communities Plan Draft Environmental Impact Statement, addressing concerns about the airport's Noise Remedy Program. It explains that noise program classifications for petition signers were upgraded due to factors such as summer flight patterns and proximity to approach paths, and that most signers were moved into the Purchase Guarantee area or recommended for the Cost Sharing Insulation Program. The response also notes that no specific schedule exists for noise remedy implementation due to uncertainties in federal funding, and that detailed land-use planning for acquisition areas will involve full citizen participation after properties are acquired.

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, Sunny Terrace, Gregory Heights, and Blakley Manor that are affected by aircraft noise. The map uses color coding to highlight the Burien Center commercial core, grid cells where program eligibility is determined by noise criteria alone, streams and ponds, and areas of heavy vegetation. It distinguishes between single-family residential structures and other building types to guide noise mitigation and land-use planning decisions in communities near the airport.

The Sea-Tac Communities Plan, sponsored by the Port of Seattle and King County, maps out noise mitigation programs for residential and other structures in communities surrounding Seattle-Tacoma International Airport. The plan designates specific zones for different types of assistance, including property acquisition, purchase guarantees, cost-sharing insulation, and limited cost-sharing insulation, with a focus on the South Reinforcement Area. Grid cells are identified by noise criteria to determine which program applies to each affected neighborhood, covering areas such as the Southwest and Southeast Conversion Areas near the airport's passenger terminal.

This exploratory draft outlines a proposed Post Project Coordination Study for the Sea-Tac Communities Plan, designed to ensure that implementation programs are carried out effectively. It identifies seven key program areas requiring coordination, including noise reduction, drainage improvements, community action, zoning guidelines, capital improvements, and legislative advocacy. The document calls for a methodical study to analyze coordination needs, define responsibilities, and assign authorities across agencies such as the Port of Seattle, King County, and the FAA.

Minutes from a community planning workshop (Meeting #4) in which residents from neighborhoods near Sea-Tac Airport — including Valley View, Riverton Heights, Marvista, Des Moines, North Hill, Shorewood, and Highline College — identified what they valued most about their communities, such as natural scenery, views, schools, and open space. Participants also discussed what regulations might be needed to protect those qualities, including building height controls, green belt preservation, clean-air policies, and safe pedestrian pathways. A comprehensive land use plan was proposed that would balance residential, industrial, recreational, and conservation needs while ensuring local residents have a meaningful voice in decisions affecting their neighborhoods.

The Sea-Tac/Communities Plan outlines three noise impact programs for managing properties affected by aircraft noise at Seattle-Tacoma International Airport. All three programs involve a designated government unit purchasing affected properties through negotiation or condemnation. The programs differ in how the land is subsequently used: Program One converts it to low-intensity open space such as golf courses or farmland; Program Two redevelops it for noise-compatible industrial or commercial uses; and Program Three leases the properties back to prior owners for a set period, leaving land use largely unchanged in the short term.
