PURPOSE/ACTION REQUESTED
Authorize the execution of a joint powers agreement (JPA) with the Vermillion River Watershed Joint Powers Organization (VRWJPO) for the Ravenna Trail Sontag Ravine Repairs Project, County Project 54-010.

To promote a safe and efficient transportation system, Dakota County, in cooperation with the VRWJPO, completed erosion stabilization on the Sontag Ravine located on County State Aid Highway (CSAH) 54 (Ravenna Trail) a half mile north of CSAH 68 (200th Street). County Project (CP) 54-010 improved safety and operations of Ravenna trail by eliminating sand and debris from washing over the road and ultimately into the Vermillion River.

These rainfall events caused damage to the previously constructed stabilization, necessitating repairs.
VRWJPO staff prepared design drawings and specifications to repair the Ravenna Trail Sontag Ravine, which is necessary to maintain compliance with the Grant Agreement (Project).
