In July 1972, the Port of Seattle Commission authorized the purchase of property around Sea-Tac Airport, bounded by 12th Ave. S., 170th St., and SR 518, to serve as a buffer and safety zone from aircraft operations. The acquisition is split equally between the Port of Seattle and the Federal Aviation Administration under an expanded FAA runway side clearance ruling. As of May 1973, a second property evaluation was underway, with acquisition procedures set to begin after final federal approval of the 163 affected parcels.

These fact sheets from 1973 outline the structure and goals of the Sea-Tac Communities Plan, a planning study focused on Sea-Tac International Airport and surrounding areas. The Community Involvement Program aimed to engage local residents through a community office, public displays, and citizen representation on advisory committees. Technical oversight was provided by the Technical Advisory Committee (TAC), which brought together representatives from local, state, and federal agencies—including the FAA, EPA, Boeing, and area school districts—to coordinate planning efforts and review recommendations.

This April 1973 fact sheet describes the formation of the Technical Advisory Committee (TAC), a group of representatives from local, state, and federal agencies organized as part of the Sea-Tac International Airport & Vicinity Master Plan Project. The TAC was established to exchange technical information, coordinate planning activities, and serve as a review forum for proposals and recommendations developed by the study team. The committee, chaired by project manager Art Yoshioka, included representatives from the FAA, EPA, Boeing, King County, the City of Seattle, and several other regional agencies and organizations, meeting monthly at the community study office in Burien, Washington.
