CDOT Region and Wetland Mitigation Bank Map

Limon Wetland Mitigation Bank

The CDOT Limon Wetland Mitigation Bank was constructed during 1996 and 1997 as a joint effort among CDOT, the U.S. Army Corps of Engineers, the Federal Highway Administration, the Town of Limon, and other federal and state agencies. The 14-acre property, owned and maintained by the Town of Limon, is approximately 90 miles east of Denver. Credits at the bank are for CDOT use only, and the service area primarily overlaps with the Lower Arkansas River drainage basin and within EPA ecoregion 26-1, Southwestern Tablelands-Grasslands.
