is 65 decibels. Based on MnDOT's scoring, the selected area did not score high enough to receive a noise wall. The estimated cost for a noise wall at the time was $2,700,000, equating to a cost to the City of$270,000. It can be assumed the cost in today's dollars is closer to $3,000,000 with a $300,000 City cost. Highway 51 and Glenhill Area hapel Q g Johanna Marsh Park® a RII Ha� A a (I\\ Gleani//qo. f v e^� Glenhl ft' HaIIQIn ather's^. se © n, ,,ems a:4ve LM Knjt ally This area was not part of previous noise study,but did have a noise measurement taken coming in at 67.1 decibels, which is also over the threshold. Since it was not part of a previous study, we do not have a cost estimate for this section,but MnDOT did note a short wall here likely isn't cost effective, and a longer wall would require cooperation with Roseville as it would likely stretch into their City. The actual application for a future noise wall is simple to complete, but would require a resolution of support from the City Council. Should the City decide to submit an application, MnDOT will then update noise studies for the areas of the submitted applications and based on their criteria will score each application. It will be important should the Council want Staff to submit an application to give direction on the area(s) it would like to submit for. Budget Impact Assuming a cost to the City of$300,000, there is not currently money set aside for a 2029 noise wall. The projected balance for the PIR fund is below, you'll note it could absorb $300,000 but other projects may need to be cut or new projects not added in the future. The City may pursue other funding mechanisms, such as, assessments, too. w $2.5 ° $2.0 $1.5 $1.0 $0.5 ■ $0.0 -$0.5 2024 2025 2026 2027 2028 2029 Attachment N/A Page 2 of 2
