MSP Aircraft Noise Analysis for 2018 Now Available

Today MAC published its annual noise contour report, assessing the actual aircraft noise exposure on residential homes near Minneapolis-St. Paul International Airport (MSP) to determine eligibility for future noise mitigation. The 2018 MSP Annual Noise Contour Analysis Report reveals an overall decrease in the contour size; however a small area in Minneapolis is reaching noise exposure levels triggering mitigation.  

The MAC has been providing residential noise mitigation to homes around MSP for decades, as detailed in the 2018 Annual Noise Contour Report. To date, the MAC has spent approximately $488 million on noise mitigation surrounding MSP since 1992. This includes sound insulation for more than 18,600 single-family and multi-family homes and 19 schools. The report contains references to the eligibility criteria for the current program and the associated legal agreements that form the "back-bone" of the current program.

Based on this year’s report, many homes around the airport have been provided noise mitigation beyond the actual noise exposure levels experienced in 2018. During 2018, MSP had 8,790 fewer flights compared to 2017. This contributed to a 137-acre reduction in the 60 dB DNL contour and a 25-acre reduction in the 65 dB DNL contour compared to 2017.  While the total size of the contours is smaller overall, the 2018 contour extends beyond the 2017 contour northwest of the airport where the 60 dB DNL arrival lobe along Runway 12R reaches across Lake Harriet. This triggers mitigation eligibility for an additional 243 single-family homes to begin in 2020.

The yellow highlighted area in the map below shows where homeowners were deemed eligible to participate in the MAC’s mitigation program in 2017-2019. The blue area highlighted in the map shows the blocks containing 243 single-family homes that have become eligible to participate in the 2020 mitigation program.

NOTE: Homeowners do not need to take any action to qualify for the MAC Residential Noise Mitigation Program. Eligibility is based on calculated aircraft noise exposure related to actual aircraft activity associated with MSP. The MAC will notify homeowners in writing once a home meets the full eligibility criteria.
