    Sea-Tac International Airport: Commercial Aircraft Noise Footprint Comparison

    This Sea-Tac International Airport brochure, prepared by the Port of Seattle in Summer 1998, compares the noise footprints of Stage II jets, Stage III jets, and general aviation/commuter aircraft to help residents understand the noise impacts of different aircraft types. It explains that Stage III aircraft are significantly quieter than Stage II aircraft, and that replacing older Stage II planes with newer Stage III models would meaningfully reduce noise levels in surrounding communities. The document also defines key noise measurement terminology, including DNL (Day-Night Average Sound Level), and notes that nighttime flights carry a 10-decibel penalty in noise accounting.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

Read This!

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.
