Screenshot of the BTS National Transportation Noise Map (maps.dot.gov/BTS/NationalTransportationNoiseMap) showing aviation noise contours in the Sea-Tac Airport corridor, with visible place names including Des Moines, Star Lake, Lakeland North, Kent, and Maury Island. The map legend displays 24-hr LAeq noise levels ranging from 45–49.9 dBA (yellow) to above 90 dBA (blue), with the airport flight path corridor showing levels predominantly in the 55–69.9 dBA range for the selected years 2016 and 2018.

Sidebar On/Off

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
