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.

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.

This 1973 U.S. Environmental Protection Agency document establishes scientific criteria for understanding how noise affects public health and welfare, including hearing damage, annoyance, communication interference, and property value loss. Prepared by EPA's Office of Noise Abatement and Control under the Noise Control Act of 1972, it describes cause-and-effect relationships between noise exposure and human health impacts. The criteria laid out in this document were intended to serve as a foundation for developing future noise standards and regulations, though the document itself does not constitute a standard or regulation.

These documents from 1973 describe the formation and early activities of the Policy Advisory Committee (PAC), established to oversee the Sea-Tac International Airport and Vicinity Master Plan Project. The committee brought together representatives from the Port of Seattle, King County, the FAA, and community citizens to monitor project progress, facilitate communication between stakeholders, and review study findings related to noise, land use, and environmental impacts. Regular monthly meetings and community task forces on topics such as noise abatement and drainage were organized to maximize public involvement in shaping airport policy.

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.
