Noise
Noise from traffic and construction on busy highways can be disruptive to people living and working nearby. The Iowa DOT does noise studies on large highway projects that could have a noise impact. There are maximum acceptable noise levels set by federal regulations and by Iowa DOT policy. If we think there might be an issue, we complete a noise study to determine if the project will cause a noise impact. We also talk to the neighbors of the highway project and try and come up with possible solutions.
