This map, prepared by Landrum & Brown for the Port of Seattle's 14 CFR Part 150 Study Update, shows projected aircraft noise exposure around Seattle-Tacoma International Airport for the year 2018. It illustrates three noise contour zones (DNL 65, 70, and 75 dBA), with the total area above DNL 65 dBA covering approximately 7.3 square miles and affecting an estimated 3,771 housing units and 9,712 residents. The map also identifies noise-sensitive land uses such as schools, churches, hospitals, and libraries within the affected area, and was certified by the Port of Seattle's Director of Aviation Planning and Environmental Programs.
