A January 1984 Port of Seattle memorandum notifies the Technical Working Committee of an upcoming meeting on January 25 to review noise remedy programs for Jackson (Sea-Tac) International Airport, including land acquisition, purchase assurance, and sound insulation proposals. Attached is a draft chapter evaluating on-airport and off-airport noise abatement measures against ten criteria, such as airspace compatibility and aircraft safety. The document outlines which measures were recommended for implementation following an initial screening process described in an earlier chapter.

In December 1983, the FAA completed an aeronautical study of a proposal by the Port of Seattle to eliminate the 'right-turn' departure route for eastbound turbojet aircraft leaving Sea-Tac Airport (Runway 34) during daytime hours. The study found that removing this route would simply shift aircraft noise to other communities, increase airline operating costs by an estimated $1.5 million annually, and raise fuel consumption, without providing a net noise reduction benefit. As a result, the Port of Seattle withdrew its proposal and the FAA declined to eliminate the existing noise abatement route.

This 1983 work program outlines a study to evaluate and update Sea-Tac International Airport's aircraft noise remedy program, originally established in the 1970 Sea-Tac/Communities Plan. The study, conducted by the Port of Seattle alongside Peat Marwick Mitchell & Co. and McClure Research Company, addresses updated noise projections, progress on existing remedies, and current financial conditions. Key tasks include study design, federal funding coordination, and a Community Involvement Program to keep the public informed and engaged in noise abatement planning.
