Letters of Map Change (LOMC)

Letters of Map Amendment (LOMA), a type of LOMC, are amendments to effective FIRMs (flood insurance rate maps) which establish that a structure or property should not be included in the floodplain due to naturally high ground.

Letters of Map Amendment and Letters of Map Revision (LOMR) enable property owners to request changes or updates to their property’s flood risk status to FEMA. Learn more about how to request a change to your flood zone designation at FEMA’s website.

Submitting a LOMA Request
