MnDOT is accepting applications this year through December 3 1 " for <br />2029 sound barrier projects. Should the City want to submit an application and be awarded a project, <br />the City would be responsible for 10 percent of the cost. The scoring for the program is based on a <br />number of factors, such as number homes served, decibel levels, and cost feasibility. A quick <br />summary is below of the two areas recently discussed: <br />Old Highway 10 from Highway 96 to South of Wedgewood Circle <br />kGn Readiness__ <br />St xa€herine <br />6r[hodax Church <br />Sync <br />Elk <br />a <br />Church© <br />3 <br />e <br />eager r - <br />This area was studied as part of a previous 2019 MnDOT Noise Study and it was found the noise <br />level in the area measured 71.2 decibels during the reading period, the threshold for a sound barrier <br />Page 1 of 2 <br />
