The project encroaches on or is in close proximity to a levee.
You are looking to floodproof or elevate your property.
You need to work with FEMA or the US Army Corps of Engineers.
The main documents for developing in a floodplain are:
1. Elevation Certificate:
Purpose: Verifies the elevation of a building’s lowest floor relative to the base flood elevation (BFE).
Requirement: Essential for new construction and substantial improvements in Special Flood Hazard Areas (SFHAs) to ensure compliance with floodplain management regulations.
2. Floodproofing Certificate:
Purpose: Documents that non-residential buildings have been designed and constructed to be watertight below the BFE.
Requirement: Required for non-residential buildings opting for floodproofing instead of elevation.
3. Conditional Letter of Map Revision (CLOMR):
Purpose: Indicates whether a proposed project will meet NFIP requirements for changing floodplain boundaries.
Requirement: Necessary before construction begins if the project will alter the floodplain.
4. Letter of Map Revision (LOMR):
Purpose: Officially revises the current FEMA flood map to reflect changes in floodplain boundaries due to completed projects.
Requirement: Submitted after project completion to update the floodplain map.
5. No-Rise Certification:
Purpose: Confirms that a proposed development will not increase flood levels within the floodway.
Requirement: Required for any development within a designated floodway.
