Des Moines jet noise decreasing, council told
The latest aircraft noise exposure maps from the Port of Seattle show that aircraft noise is decreasing in Des Moines.
The city of Des Moines may soon modify their 15-year-old building codes concerning airport noise control.
“Airplanes are getting quieter … and the third runway supports more incoming flights than take-offs,” said City Manager Tony Piasecki.
Without the noise levels, the council no longer saw a need for stringent noise reduction requirements for building in their city.
At the March 1 Des Moines City Council meeting Grant Fredricks, Planning, Building & Public Works director, presented new data from the Port of Seattle’s “Part 150” study to the council. The data shows a significant amount of reduction in air traffic noise for the southern part of Des Moines.
The “Part 150” study was developed by the Port in the ‘90s to identify areas of high-level air traffic noise in the Sea-Tac Airport’s surrounding cities and neighborhoods. The ongoing study provides communities with current sound data for the areas in their flight corridor.
