We can request a Conditional Letter of Map Revision (CLOMR) from FEMA for projects that will change a flood area. This letter is a conditional approval from FEMA about the changes that one of our projects will make.
The CLOMR does not revise a NFIP map. It only indicates whether the proposed project will be recognized by FEMA. Building permits cannot be issued based on a CLOMR, because a CLOMR does not change the NFIP map.
We can request a revision to the Flood Insurance Rate Map (FIRM) to reflect a finished project. "As-built" designs and other data is used to support the revision request.
We can request a Letter of Map Revision (LOMR) when a project is complete. This is a formal process to change FEMA's Flood Insurance Rate Map (FIRM), or Flood Boundary and Floodway Map (FBFM), or both.
LOMR are based on physical changes that impact the way water flows and the location or course of a river or stream. These changes may impact flood elevations and hazard areas.
