If the property is in an "A" or "V" zone, flood insurance is required regardless of the elevation of the property.
If the property is not in an "A" or "V" zone, you may use elevation information to file a Letter Of Map Amendment or Revision (LOMA/LOMR) with the Federal Emergency Management Agency (FEMA). While FEMA reviews the LOMA/LOMR, flood insurance is still required. If FEMA approves the LOMA/LOMR, you may not be required to maintain flood insurance or your premium may be reduced.
