FEMA Letter of Map Revision (LOMR) Review Partner

In 2019, FEMA opened the LOMR Review Partners Program to new partners. The DNR Division of Water has wanted to review LOMRs since it first became a Cooperating Technical Partner in 2004. The organization and experience of the DNR in floodplain management and regulatory programs allows us to effectively manage the LOMR process, resulting in process improvements and ultimately a stronger floodplain management program. LOMA and LOMR-F will continue to be reviewed by FEMA’s contractor.

MT-2 submissions for the State of Indiana will be accepted at:

Indiana Department of Natural Resources
Division of Water
402 W. Washington Street, Rm W264
Indianapolis, IN 46204

or online at:
