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.Open full document
