Overview:
Four Mile Mitigation Bank is a 43-acre bank located in Preble County, Ohio within the Lower Great Miami Watershed. In addition to generating stream credits for the Lower Great Miami watershed, the primary service area for Four Mile will also consist of the Whitewater and Middle Ohio-Laughery combined watersheds. Four Mile Mitigation Bank was approved by the U.S. Army Corps of Engineers in consultation with the Ohio Interagency Review Team in November 2025.
Four Mile aims to restore existing eroded and channelized streams, improve in-stream habitat, re-establish and rehabilitate riparian areas to increase agricultural runoff filtering capacity, improve bank stability and improve wildlife habitat quality, just to name a few.
