What is a CLOMR?
A Conditional Letter of Map Revision, or CLOMR, is FEMA’s comment on a proposed project that may change the floodplain or probability of flooding. Receiving a CLOMR is the first step in certifying property is protected from a 100-year flood event.
- A CLOMR does not revise the current National Flood Insurance Program (NFIP) map. It just outlines whether the project, if built as proposed, would be recognized by FEMA.
- Building permits cannot be issued based on a CLOMR, because a CLOMR does not change the NFIP map.
- Once a project has been completed, the community must request a revision to the Flood Insurance Rate Map (FIRM) to reflect the project. “As-built” certification and other data must be submitted to support the revision request.
Does this affect my flood insurance?
No, not yet. The FM Area Diversion Project is a federal project that will provide certifiable flood protection for hundreds of thousands of people in the Fargo and Moorhead area by 2027. It was designed to prevent impacts from a 100-year flood event. Once built and certified by FEMA, the mandatory flood insurance requirement for thousands of people will be removed.
What happens after a CLOMR?
Once the FM Area Diversion is ready to operate, the MFDA will ask FEMA to look at its flood map and lift the insurance requirement since the project will provide certifiable protection. The requirement can be lifted with a Letter of Map Revision, or LOMR.
