This document summarizes the Sea-Tac Communities Plan, a 1973 joint study by the Port of Seattle and King County to improve compatibility between Sea-Tac International Airport and its surrounding neighborhoods. The plan examined aircraft noise exposure, air and water quality, and community growth, finding that noise levels were expected to decrease over time due to quieter aircraft technology despite rising flight operations. It proposed a range of noise remedy programs—including property acquisition, purchase guarantees, and insulation assistance—affecting thousands of homes in areas north and south of the airport.Open full document

The document covers background on the airport and community, air traffic forecasts through 1993, environmental findings including air quality, noise exposure, and water quality studies, and a noise remedy program with specific application areas for acquisition, purchase guarantee, and insulation programs.
