In 1983, the Port of Seattle launched an update to its Sea-Tac International Airport Noise Remedy Program, originally established in the 1976 Sea-Tac/Communities Plan, to address changes in aircraft noise patterns, finances, and community needs. The update aimed to reassess and revise noise reduction measures after noise levels shifted unexpectedly—decreasing in some areas northeast and southeast of the airport while increasing to the east and west. Public workshops and community involvement were central to the process, with a recommended updated program targeted for presentation to the Port Commission by mid-1985.Open full document

This fact sheet from the Port of Seattle describes the Sea-Tac International Airport Noise Remedy Program Update, a planning study initiated in April 1983 to re-evaluate and update the noise remedy element of the 1976 Sea-Tac/Communities Plan. It outlines actions already taken under the original program, explains why an update is needed due to changes in noise patterns, finances, and community goals, and describes how local governments and communities will be involved through public workshops and advisory committees.
