FEMA Floodmapping Analysis | Elevation Certificates


FEMA Flood Zone Remapping Services

Changing My Flood Zone Designation

CLE Engineering can provide topographic survey, wave and wind modeling, and FEMA Letter of Map Revision (LOMR) services for residential and commercial clients.  CLE has successfully removed many structures from VE Zones completely. Many times our engineers are able to prove a structure or property is located above the flood zone or that the zone designation itself is incorrect. The result is reduced flood insurance premiums or less stringent Building Code standards for a renovation or new structure.

What is a Elevation Certificate

The Elevation Certificate is an important part of the floodplain management process. It certifies the elevation of a structure. It is also used to determine the proper insurance premium rate and/or to support requests for a Letter of Map Amendment (LOMA), Letter of Map Revision (LOMR) or Letter of Map Revision based on Fill (LOMR-F).  An accurately completed Elevation Certificate can potentially cost a homeowner thousands of dollars in insurance premiums.

What is LOMR

A Letter of Map Revision (LOMR) is the Federal Emergency Management Agency’s (FEMA’s) official modification to an effective Flood Insurance Rate Map (FIRM). LOMRs can result in a physical change to the existing regulatory floodway, the effective Base Flood Elevations (BFEs), or the Special Flood Hazard Area (SFHA).

CLE has successfully performed revised wave and wind calculations as part of a LOMR to challenge the effective Flood Insurance Rate Map. These revised calculations have resulted in the removal of structures and parcels, which were previously in VE/AE Zones, from the Special Flood Hazard Area entirely.

What is LOMA

A Letter of Map Amendment (LOMA) is an official amendment, by letter, to an effective National Flood Insurance Program (NFIP) map. A LOMA establishes a property”s location in relation to the Special Flood Hazard Area (SFHA). LOMAs are usually issued because a property has been inadvertently mapped as being in the floodplain, but is actually on natural high ground above the base flood elevation.

CLE has successfully performed the survey and analysis required to remove structures from the Special Flood Hazard Area. A successful LOMA application often will remove the requirement for flood insurance and restrictions on renovations.
