TagSea-Tac Airport(1001)

This document outlines a development concept addressing the relationship between Sea-Tac International Airport and its surrounding communities. While the airport contributes significantly to the regional economy—supporting over 15,200 jobs and $390 million in annual business activity—local residents have long struggled with aircraft noise, uncertainty about airport expansion, and the impact on property values and neighborhood character. The concept seeks to find greater compatibility between the airport's growth and the needs of the communities it affects.

In September 1973, the Port of Seattle outlined a plan to acquire approximately 610 residential properties and 75 acres of open land surrounding Sea-Tac International Airport to create expanded clear zones north and south of the runways. The total estimated property cost was $15.46 million, with the Port anticipating over $8 million in federal FAA assistance and covering the remainder from airport revenues between 1974 and 1977. Under the best-case scenario, actual land acquisition could not begin until after July 1, 1974, following required environmental impact statements, housing relocation plans, and a multi-month FAA review process.

A 1973 Port of Seattle memorandum outlines a proposed interim land acquisition program around Sea-Tac International Airport, targeting properties to the north and south of the airport's existing boundaries to establish expanded clear zones. The plan covers approximately 610 residential parcels and 75 acres of open land valued at an estimated $15.46 million, with the Port seeking over $8 million in Federal Aviation Administration funding to offset costs. Land acquisition was projected to begin no earlier than July 1, 1974, following required environmental impact statements, housing relocation plans, and FAA review and approval.

Minutes from a June 28, 1973 Air Transportation Committee meeting on the Sea-Tac Communities Plan, held in Burien, Washington. Representatives from the Port of Seattle, FAA, Highline School District, and local community groups discussed the history of Sea-Tac Airport's expansion, the impact of aircraft noise on nearby schools and neighborhoods, and ongoing efforts to measure and reduce noise exposure. Key topics included new comprehensive noise measurement methods, federal agency roles in noise regulation, and strategies for noise abatement such as modified flight procedures and sound-absorbing materials.

Minutes from a June 21, 1973 Urban Development Committee meeting on the Sea-Tac Communities Plan, held in Burien, Washington. The meeting covered the need for updated environmental and zoning studies in the Highline area due to airport impacts, a community opinion survey from White Center residents, and a water quality and drainage study. Officials discussed developing a focused 'middle plan' for the Highline area to better address local needs and airport-related land use challenges.
