Noise Analysis

Greater MN stand-alone noise barrier program

The Greater MN Stand-Alone Noise Barrier Program was recommended by the Office of the Legislative Auditor who stated that “MnDOT should create a pathway for communities outside of the metropolitan area to become eligible for state-funded noise barrier projects.”

Future applications will be accepted annually from October 1 through December 31. Projects will then be selected before June of the following calendar year. Selected projects will generally take about 3 years to design and construct from the time of selection.


Where would the Greater MN Program apply?

All of the following are required for a location to be eligible for the program:

  • Within incorporated jurisdiction
  • Adjacent to a limited access Freeway, Expressway, or Interstate
  • Currently approaches or exceeds FHWA Noise Abatement Criteria (NAC)
  • Homes constructed prior to 1997 (date of legislation)
  • Does not require a right-of-way purchase
  • Not adjacent to a future project which would require a noise analysis and which is identified in the 10 year plan

What will be required from the city/township?

  • Commit to pay 10% of the total noise barrier costs
  • Formal application from the city/township
  • Resolution of support from city council
  • Maintenance on the residential side of the noise barrier

What will be performed by MnDOT?

  • Accept and score/rank applications
  • Conduct a preliminary and final noise analysis based on traffic volumes, density of homes, and cost
  • Notify Districts and applicants of proposed projects

What will be performed by MnDOT District Office?

  • Preliminary and final design for the noise barrier
  • Construction contract administration
  • Maintenance, as defined in MnDOT’s cost participation policy
