1978-09-01Policy Advisory Committee for Sea-Tac Plan Implementation
★This 1978 document outlines the structure and functions of a Policy Advisory Committee (PAC) formed to oversee implementation of the Sea-Tac Airport Communities Plan, including long-term monitoring of airport noise issues and making recommendations to King County and Port of Seattle officials. The 12-member committee draws representatives from King County, local governments, businesses, schools, airlines, and community citizens. It also details noise exemption rules for daytime aircraft testing and maintenance at Seattle-Tacoma International Airport, specifying conditions such as permitted hours (7 a.m. to 10 p.m.) and geographic boundaries defined by the 'NEF 45' noise exposure contour line. -
1976-09-20Ordinance No. 2883: An ordinance adopting the Sea-Tac Communities Plan
★ 32King County Ordinance No. 2883, passed in September 1976, officially adopted the Sea-Tac Communities Plan as an addendum to the King County Comprehensive Plan, establishing it as the guiding policy for land use, development, and redevelopment around Sea-Tac International Airport. The plan, developed with Federal Aviation Administration grant funding and extensive community involvement, addresses noise programs, open space acquisition areas, and compatible land use in the airport's vicinity. It required coordination between King County and the Port of Seattle on any future changes, with the Highline Communities Plan designated as the official zoning guideline for implementing its land use concepts. -
1976-06-08Resolution No. 2626: A resolution establishing planning and developmental policies relating to Sea-Tac International Airport and its vicinity
★Resolution No. 2626, adopted by the Port of Seattle Commission on June 8, 1976, formally accepted the Sea-Tac/Communities Plan as a guide for developing Sea-Tac International Airport in a way that maximizes compatibility with surrounding neighborhoods. The resolution directed Port staff to pursue federal funding for land acquisition in flight path zones, establish an aircraft noise monitoring system, and launch a pilot acoustic insulation program for nearby homes. Total noise abatement efforts were estimated to cost approximately $50 million over a ten-year period, with funding expected from airport revenues and federal assistance. -

The Sea-Tac Communities Plan, jointly developed by the Port of Seattle and King County beginning in 1973, outlines strategies to improve compatibility between Sea-Tac International Airport and surrounding neighborhoods, with a focus on aircraft noise remedies, water quality improvements, and land use conversion. The plan identifies specific areas for outright property acquisition, purchase guarantees, and noise insulation programs affecting thousands of homes north and south of the airport. It also establishes policies for drainage management, community development, and long-term airport facility improvements to accommodate projected air traffic growth through 1993. -
2026-07-15Sea-Tac Communities Plan: Water quality, airport, and community development
The Sea-Tac Communities Plan outlines strategies to improve compatibility between Seattle-Tacoma International Airport and surrounding neighborhoods, focusing on water quality, drainage, and land use. Key programs include public acquisition of noise-impacted residential areas for open space and recreation, conversion of single-family zones to higher-density or commercial uses, and reinforcement of existing neighborhoods through noise remedy and infrastructure improvements. The plan also addresses environmental concerns such as stream protection, holding pond systems for stormwater management, and pollution control near Miller and Des Moines Creeks. -
2026-07-15Sea-Tac Communities Plan background and environmental findings
This document summarizes the Sea-Tac Communities Plan, a 1973 joint study by the Port of Seattle and King County to improve compatibility between Sea-Tac International Airport and its surrounding neighborhoods. The plan examined aircraft noise exposure, air and water quality, and community growth, finding that noise levels were expected to decrease over time due to quieter aircraft technology despite rising flight operations. It proposed a range of noise remedy programs—including property acquisition, purchase guarantees, and insulation assistance—affecting thousands of homes in areas north and south of the airport. -

This document is a map supplement to the sixth-month element report for the Sea-Tac Communities Plan, a planning study sponsored by the Port of Seattle and King County and partially funded by a federal FAA grant. It covers five key topics—community trends and characteristics, land use, ground transportation and traffic, aesthetic and visual characteristics, and natural determinants—for the communities surrounding Seattle-Tacoma International Airport. The supplement includes 1970 census tract maps of the Sea-Tac area and an errata note correcting a data classification error for Census Tract 272 related to public assistance recipients. -

The Sea-Tac Communities Plan really was a plan. Because Sea-Tac Airport was sited in a growing area, the Second Runway expansion presented huge challenges. Sea-Tac became the ‘alpha-tester’ for many FAA initiatives. The question they were trying to answer was: how can any major airport function in harmony with its surroundings? One idea, which the
