Letters of Map Change
What is a Letter of Map Change?
In situations where a property owner thinks their property was inadvertently mapped in a Special Flood Hazard Area (SFHA) on a Flood Insurance Rate Map (FIRM0, also known as a flood map, FEMA provides a process to request a change in the flood zone designation for the property. The request is known as a Letter of Map Change (LOMC).
A LOMC is a general term used to refer to the several types of revisions and amendments to FEMA maps that can be accomplished by letter. They include Letter of Map Amendment (LOMA), Letter of Map Revision (LOMR), and Letter of Map Revision Based on Fill (LOMR-F).
The FEMA website contains more detailed information on LOMCs.
