Past Noise Mitigation in Minneapolis

While the City of Minneapolis recognizes the value that the airport brings to the Twin Cities, it also recognizes that our residents deserve protection from noise pollution. A 2005 lawsuit led to an agreement with the the Metropolitan Airports Commission (MAC) to provide noise mitigation to homes who were experiencing, or were expected to experience, an increase in airplane noise.

The Cities of Minneapolis, Richfield and Eagan, as well as the Minneapolis Public Housing Authority, filed a lawsuit against the Metropolitan Airports Commission (MAC) in 2005 seeking to require the MAC to provide homes with noise abatement (insulation and/or air conditioning, for example) help. The cities’ lawsuit was based on the premise that the MAC violated the Minnesota Environmental Rights Act by impairing airport neighbors’ right to quietude and violating an environmental standard that was created when the MAC agreed to expand its existing noise relief program to the 60 DNL (day/night noise level) contour.

On Jan. 15, 2008, all conditions for a $127.6 million settlement in the cities’ lawsuit were met. That cleared the way for some form of noise mitigation for more than 9,560 homes in Minneapolis, Richfield, Eagan and Bloomington. Plaintiffs in a separate airport noise class action lawsuit (Wiencke et al vs. MAC) agreed to settle their lawsuit in a manner consistent with the cities’ lawsuit.  All phases of mitigation provided under this original agreement are now complete.  However, it 2013, the parties to the consent decree entered into a First Amendment to the consent decree which created ongoing obligations for mitigation under slightly different terms.
