Letter of Map Change (LOMC)

The delineation of the floodplain limits can change. If a developer wishes to alter and/or fill a portion of the floodplain, they must prepare a Flood Study showing no adverse effects or substantial changes in the water surface elevation. This flood study, along with a detailed application, may be submitted to FEMA to be considered for a Letter of Map Revisions (LOMR).

If approved, the LOMR serves as an official revision to the FIRM. Individual property owners may also contest the floodplain designation for their property by submitting information to FEMA for a Letter of Map Amendment (LOMA).

The city has received many LOMRs and LOMAs within our city limits. Lenders and Insurance Companies are not always aware of these changes, so it may be necessary to call the Community Development Department to determine if the floodplain map for your area has changed and to receive a copy of the change. Many Letters of Map Change can also be obtained online from the FEMA Flood Map Store.
