What is a LOMR?
LOMR stands for Letter Of Map Revision. FEMA (the Federal Emergency Management Agency) surveys areas and creates maps that reflect flood zones within those areas. If, at a later date, the geographic region changes in such a way as to reduce or remove a flood zone, such as when channels and basins are constructed in the area, FEMA may create a LOMR. The LOMR details the changes to a map that remove certain areas from a flood zone.
