A nomination letter from Geraldine Van Notric, a Hillgrove Cemetery Board Member, requests that Hillgrove Cemetery — located near Sea-Tac International Airport at 200th Street and 16th Ave. So. — be designated a King County Historic Site under Ordinance No. 4828. The cemetery, established with its first burial in 1900 and formally organized as an association in 1923, contains graves of pioneers who shaped the Highline area's economic development, as well as military veterans from the Civil War and World War I. The nomination emphasizes that the designation would provide community recognition and protection for the site, not serve as a request for county repair funds.

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.

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.

The Sea-Tac Airport Sustainable Airport Master Plan (SAMP) Near-Term Project Environmental Review outlines a comprehensive set of planned improvements at Seattle-Tacoma International Airport, covering airside, landside, terminal, cargo, and airport support facilities. Key projects include taxiway and runway upgrades, a new second terminal with associated roads and parking, cargo facility expansions, and sustainability initiatives such as sustainable aviation fuel infrastructure and consolidated de-icing tanks. These near-term projects are intended to enhance airport capacity, safety, and operational efficiency while supporting the airport's long-term growth strategy.

This map presents the concept design for the Auburn wetland mitigation site as part of the Port of Seattle’s Wetland Mitigation and Habitat Conservation Umbrella Bank Prospectus. The figure shows five delineated wetlands (A through E) along the Green-Duwamish River, with proposed enhancements including wetland re-establishment, buffer enhancement, upland enhancement, and re-routed ditches.
