Commissioner Fabel requested further information regarding how the Round Lake remediation project would be completed. He questioned why the sediment from the lake would be stored on Rice Lake Commons property. Ms. DeWalt explained moving the material off site was looked at within the feasibility study and was determined to be less efficient. She commented this project would take six months to complete and the County does not believe the placement of this material on Rice Creek Commons property would impede the overall development. Director Collins added in conversations with the Army they have agreed to not disrupt or impact this project. She noted the contaminants within Round Lake were not concerns for human life, but rather were ecological contaminants that impacted plants and fish.
