7th Avenue Creek – Conditional Letter of Map Revision (CLOMR)

The City of St. Charles has requested Illinois Department of Natural Resources, Office of Water Resources (IDNR-OWR) concurrence with a regulatory floodway map and flood profile revision on 7th Avenue Creek.  The proposed floodway map and flood profile revision is the result of an updated flood study of 7th Avenue Creek and flood control improvements identified as part of the Master Plan Development process by the City of St. Charles.  The project reach extends from the Fox River to Tyler Road, a distance of about 2 miles. 

The improvements include the removal and replacement of numerous roadway crossings and channel work. The review and approval by the IDNR-OWR will ensure that any future improvement projects completed by the City will meet the requirements for reduction of the regulatory floodway map and flood profile revision on the 7th Avenue Creek through a Letter of Map Revision (LOMR) process.
