    City of Sea-Tac Noise Contours Map: Sea-Tac Airport Projected 2018 DNL Levels

    This map from the City of SeaTac shows projected 2018 average day/night noise levels (DNL) radiating from Seattle-Tacoma International Airport, with contour zones indicating areas expected to experience noise levels of 65, 70, and 75 decibels. The noise contours extend north into Burien, south into Des Moines, and affect portions of Tukwila and Normandy Park, with the most intense noise zone (DNL 75) centered directly over the airport. Prepared in March 2015 using Port of Seattle Airport Noise Programs data from July 2014, the map serves as a planning reference for land use and noise mitigation policy in surrounding communities.

    Existing (2013) baseline compared to future (2018) baseline noise exposure contour

    This exhibit from the Seattle-Tacoma International Airport 14 CFR Part 150 Noise Study compares the existing 2013 baseline noise exposure contours with projected 2018 baseline contours around Sea-Tac Airport. The data shows that the DNL 65+ dBA noise contour area is expected to shrink from 7.3 to 5.9 square miles, with affected housing units dropping from 3,771 to 1,887 and estimated population exposure falling from 9,712 to 4,879. Nine noise-sensitive facilities remain within the contour in both scenarios, and the maps illustrate how the impacted area covers portions of SeaTac, Burien, Des Moines, Tukwila, and unincorporated King County.

    Exhibit G-1: Future (2021) NEM/NCP Noise Exposure Contour

    This map, prepared by Landrum & Brown on January 22, 2013 as part of the 14 CFR Part 150 Study for Seattle-Tacoma International Airport, shows projected future (2021) noise exposure contours around Sea-Tac Airport at DNL 65, 70, and 75 dBA levels. The contours extend across surrounding communities including SeaTac, Burien, Des Moines, Tukwila, and portions of Renton and Kent, with sensitive land uses such as schools, churches, hospitals, and residential areas identified within the noise impact zones. The study was conducted to inform noise compatibility planning and policy decisions aimed at reducing aviation noise impacts on affected neighborhoods.
