Minutes from February 1974 Port of Seattle Commission meetings document the adoption of Resolution No. 2516, which authorized the Port to acquire approximately 421 acres of land north and south of Sea-Tac International Airport through condemnation or negotiation. A public hearing drew significant community attendance, including residents of the Zone 3 area near the airport, who expressed support for the plan while requesting that the southern boundary be extended to S. 216th Street. The meetings also addressed related airport operational matters, including modifications to airport rules and charges.

A January 30, 1974 letter submitted to David M. Des Voigne of the Port of Seattle presents a petition signed by more than 80 property owners requesting that South 216th Street be established as the southern boundary of an interim land acquisition project near Sea-Tac Airport, bounded by 24th Ave. S. to the east and proposed Highway 509 to the west. The petitioners sought to remove the most severely noise-impacted residences from the expanded clear zone. The letter also cites FAA policy under the Airport and Airway Development Act of 1970, which encourages land acquisition to accommodate both current and long-term airport development needs.

In September 1973, the Port of Seattle's Director of Aviation recommended an interim land acquisition program around Sea-Tac International Airport, targeting approximately 610 residential parcels and 75 acres of open land in clear zones north and south of the runways. The estimated cost of the acquisitions was $15.46 million, with the FAA expected to contribute over $8 million and the Port of Seattle covering the remaining $8 million from airport revenues between 1974 and 1977. Under the best-case timeline, actual land purchases could not begin until after July 1, 1974, following completion of environmental impact statements, housing relocation plans, and FAA review.

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.

These are King County, Washington property records from June 1923, including a real estate purchase contract, a quit-claim deed transferring land to Hill Grove Cemetery Association, and an assignment of a real estate contract. The documents cover property transactions in the greater Seattle area, detailing payment terms, land descriptions, and notarized acknowledgments. These records are part of the historical King County Auditor's deed registry and are not directly related to Sea-Tac Airport noise policy.
