Residential Noise Mitigation Program
In 1992 the MAC began the noise mitigation program by providing acoustical modifications for homes subject to aircraft noise impacts in the area defined by the 1996 65-dB DNL noise exposure map. Under this program, 7,846 single-family homes and 1,166 multi-family units were mitigated at a total cost of more than $243 million.
The acoustical modifications of this program involved installing new or re-conditioned windows and doors, central air-conditioning, wall insulation and vent baffling as determined by the construction design process at each home. The goal of the mitigation was to reduce interior noise levels by a minimum of five decibels.
In April 2005, the MAC began mitigating 156 single-family homes within the City of Bloomington that are located within the forecasted 2007 65 DNL noise exposure map. Eight homes within in the City of Richfield were acquired at the request of the City.
Several multi-family buildings (located in Bloomington and Richfield) are also eligible for mitigation under the forecasted 2007 65 DNL map.
In 2007, the MAC voted to approve a proposed settlement in a noise mitigation lawsuit brought by the cities of Minneapolis, Richfield and Eagan. As a result of that settlement, the MAC will provide mitigation to homes in the forecasted 60 to 64 DNL contours. Mitigation activities will vary based on noise contour, with homes in the most noise-impacted contours eligible for more extensive mitigation than those in less-impacted areas. Multi-family dwellings (those with more than three living units) will receive less extensive mitigation than single-family homes.
