The Port of Seattle is updating its Part 150 noise study for Seattle-Tacoma International Airport, which includes a revised Noise Remedy Boundary based on 2018 future noise contour projections.

Continuing programs under the update include sound insulation assistance for both single-family homes and owner-occupied multi-family residences located within the new noise remedy boundary.Open full document
