The Office of the Legislative Auditor presented the results of its study of MnDOT noise barriers. The report highlights several areas where MnDOT policies and practices need improvement.
The report found that MnDOT is more likely to build noise barriers than similar states, citing MnDOT policies and state noise standards.
Additionally, the study found MNDOT's procedure for listening to and responding to community input has a built in tendency to favor building barriers, even in the face of community objections.
The report found that MnDOT's formula for determining when and where noise barriers are built is unfair to some communities that are impacted by highway noise. According to the report, some communities have had to wait a decade for noise abatement.
Finally, the report cites MnDOT's lack of transparency when making key decisions; for example MnDOT primarily uses wood to build noise walls when other states use a variety of different materials.
MnDOT says it largely agrees with the findings of the report and that department is already working on changing appropriate policies and procedures.
