This map document illustrates the planned Third Runway expansion at Seattle-Tacoma International Airport, showing the proposed runway location, construction staging area, and fill 'borrow' areas in the Sea-Tac region. The map covers surrounding communities including Burien, Normandy Park, and Des Moines, and highlights nearby waterways such as Des Moines Creek, Miller Creek, and Walker Creek that could be affected by construction. Based on the 1996 Port of Seattle EIS Sea-Tac Airport Master Plan and 1997–1998 King County Wetlands Maps, the document provides geographic context for environmental and land-use planning related to the runway project.

This document presents the Noise Remedy Update for Jackson International Airport (Sea-Tac), operated by the Port of Seattle, outlining the overall program boundaries for noise mitigation efforts in surrounding communities. It includes detailed maps showing three categories of noise remedy zones: Acquisition (properties purchased by the Port), Purchase Assurance (properties guaranteed a buyer), and Sound Insulation (properties eligible for noise-reduction improvements). The affected areas span multiple neighborhoods north and south of the airport, including White Center, Boulevard Park, Normandy Park, Des Moines, and parts of Kent and Renton.

This map illustrates the F.A.A. density guidelines for the North Sea-Tac Park area, showing recommended population limits per acre across different airport safety zones. The Clear Zone nearest the runway allows the fewest people (approximately 1.5 per acre), while the Extended Clear Zone permits around 2 people per acre, and surrounding residential areas are guided toward densities of 20 to 40 people per acre. A gymnasium is specifically noted at 60 people during games, reflecting how land use intensity is regulated based on proximity to airport flight paths.

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.

The Sea-Tac/Communities Plan is a planning study co-sponsored by the Port of Seattle and King County, funded through a federal grant under the Airport and Airways Development Act of 1970. It serves as a map supplement to a sixth-month report, covering community trends and characteristics, land use, ground transportation and traffic, aesthetic and visual qualities, and natural determinants in the communities surrounding Seattle-Tacoma International Airport. The 1973 report includes demographic data such as median age, the percentage of residents under 20, and the percentage of residents 65 and older, mapped across 1970 census tracts in the Sea-Tac area.
