The fiscal impact for this project will come from the 2601 Fund, for the Recovery and Resiliency Division subdivision projects with the long-term goal of reducing drainage costs in the future. No impact to staffing anticipated.

The County could elect to fund the requested task or choose to reject it. However, if not approved, the unutilized grant funds will not be used to compensate the contractor for completing the scope of the work.
