Flood Map Revisions<br />
There Are Three Primary Types <strong>of</strong> Flood Map Revisions<br />
1.<br />
2.<br />
Letter <strong>of</strong> Map Amendment (LOMA) – issued when a property owner<br />
demonstrates that the natural ground is higher than the BFE (see page 15).<br />
Lenders may waive the flood <strong>in</strong>surance requirement if the LOMA documents<br />
that a home is not <strong>in</strong> the mapped floodpla<strong>in</strong>.<br />
Letter <strong>of</strong> Map Revision Based on Fill (LOMR-F) – issued when fill has been<br />
placed to raise the land above the BFE. For multiple lots, the applicant must<br />
certify compaction <strong>of</strong> the fill. Lenders can waive the <strong>in</strong>surance requirement if<br />
the LOMR-F demonstrates that homes on fill are above the BFE.<br />
