Sea-Tac Communities Plan Chapter 6 — South Reinforcement Area Program Application Map
A planning map from the Sea-Tac Communities Plan, sponsored by the Port of Seattle and King County, depicting the South Reinforcement Area program application including the Southwest Conversion Area, Woodside School, and Manhattan Elementary. The legend identifies land-use and noise-mitigation categories including current airport lands, acquisition zones, purchase guarantee areas, cost-sharing insulation, and grid cells defined by noise criteria (e.g., N-17). -
Sea-Tac Communities Plan Chapter 6 Page 22 — Southeast Conversion Area Map
This is page 22 (section 6.6.4) of the Sea-Tac Communities Plan, sponsored by the Port of Seattle and King County. The map depicts the Southeast Conversion Area near Seattle-Tacoma International Airport, showing grid cells, acquisition areas, current airport lands, key circulation features including S.R. 509 and South Airport Access road, and named landmarks such as Angle Lake Elementary, Lowe's Terrace, Des Moines Creek, and street references including S. 188th St. and S. 200th St. -

This is page 12 (document reference 6.6.4, POS 21178) of the Sea-Tac Communities Plan, co-sponsored by the Port of Seattle and King County. The map depicts the North Conversion Area near Seattle-Tacoma International Airport, showing current airport lands, grid cells subject to noise-criteria program application, conversion area boundaries, key circulation features, the Ferrucci Addition, a postal facility, Riverton Heights Elementary, S. 152nd and S. 154th Streets, 24th Ave S., 32nd Ave S., Pacific Highway South (SR 99), the North Airport Freeway, and SR 518. -
Sea-Tac Communities Plan: Des Moines Creek Drainage Sub-Areas and Runoff Sources
A planning map from the Sea-Tac Communities Plan (document POS 21002, section 6.3.3) showing drainage sub-areas for Des Moines Creek, with impervious surface factors ranging from under 20% to 50% or greater, and annotating that 80% of total runoff originates from the northern sub-areas and 20% from the southern sub-areas. Sponsored by the Port of Seattle and King County. -
Sea-Tac Communities Plan: North Reinforcement Area Program Application
This planning map, document number 6.6.5, is from the Sea-Tac Communities Plan sponsored by the Port of Seattle and King County. It depicts the North Reinforcement Area program application, showing grid-cell zones color-coded by noise mitigation category—including acquisition, purchase guarantee, cost-sharing insulation, and limited cost-sharing insulation—for the residential area surrounding Seattle-Tacoma International Airport, with landmarks such as Cedarhurst Elementary, Boulevard Park Elementary, Hilltop Elementary, Glacier High, and Sunset Junior High visible. -
2026-01-06Sea-Tac Communities Plan: Airport Vicinity Area and Planning Jurisdictional Area (Section 3.2.1)
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. -
2023-08-22Sea-Tac Communities Plan: West Reinforcement Area Map (Section 6.6.5)
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. -
2023-08-22Sea-Tac Communities Plan: South Reinforcement Area Program Application (Section 6.6.5)
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. -
2023-08-22Exploratory draft: Post project coordination study
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. -
2023-08-22Sea-Tac/Communities Plan work program: Project overview and inventory
This document outlines the Sea-Tac/Communities Plan, a collaborative airport master planning study conducted by the Port of Seattle and King County with FAA funding, covering environmental, demographic, economic, and land-use impacts of Seattle-Tacoma International Airport on surrounding communities. The $642,000 study, two-thirds funded by a $427,978 FAA planning grant, hired multiple consultants to examine issues including noise exposure, air quality, water quality, and public opinion. The inventory phase aimed to compile comprehensive existing-conditions data within the first six months of the project, starting March 19, 1972.
