LETTERS OF MAP CHANGE

A Letter of Map Change (LOMC) is a letter issued by FEMA that reflects an official amendment or revision to the effective Flood Insurance Rate Map. The term LOMC is used to collectively reference the procedures for a Letter of Map Amendment (LOMA), Letter of Map Revision Based on Fill (LOMR-F), or Letter of Map Revision (LOMR). The County must review LOMR-F applications before they are submitted to FEMA. A LOMC application is submitted to FEMA to change the flood zone of a structure, property, or a portion of a property that are located in Special Flood Hazard Areas, which includes Zones VE, AE, AH, or A. 

The Floodplain Management section has created two webpages to assist homeowners and professionals with the LOMC process. The Homeowner Reference webpage is dedicated to assist homeowners with the submission of LOMAs and LOMR-Fs to remove a structure from the SFHA. The Professional Reference webpage is dedicated to assist professionals with the LOMC application submissions. The Professional Reference page also has additional information about LOMRs. Both webpages explain the LOMA and LOMR-F application requirements in detail, but it is important to remember that LCG is required to review all LOMR-F applications before submittal to FEMA.

To see if an address has a Letter of Map Change, you can use the National Flood Hazard Layer (NFHL) Viewer.

If you have a LOMC case number, but need a copy of the document, you can use the Map Service Center product search tool.
