Flood zones and elevation certificates0 answersAI answer
The FEMA map puts my lot in a high-risk zone, but the house sits higher than the street. Is there a way to change that?

Possibly. FEMA has a process for that [1].
- LOMA (Letter of Map Amendment): if your lot or building is naturally above the base flood elevation, you can ask FEMA to remove it from the high-risk zone.
- LOMR-F: a similar request when the land was raised with fill.
- Both usually need accurate elevation data, typically an elevation certificate prepared by a licensed surveyor.
Typical steps:
- Have a surveyor measure the elevations of the lowest adjacent ground and the structure, tied to the correct datum.
- Compare them with the base flood elevation.
- If they're above it, submit the request with FEMA's forms or online system.
A LOMA can change insurance requirements, but lenders may still ask for coverage. Talk with your insurance agent too.
