Documentation of certification by a registered professional engineer or architect that the design and methods of construction of a nonresidential building are in accordance with accepted practices for meeting the floodproofing requirements in the community's floodplain management ordinance. This documentation is required for both floodplain management requirements and insurance rating purposes.
For insurance rating purposes, a building's floodproofed design elevation must be at least one foot above the Base Flood Elevation (BFE) to receive full rating credit for the floodproofing. If the building is floodproofed only to the BFE, the flood insurance rates will be considerably higher.
Communities are encouraged to use the one-page FEMA floodproofing certification form because it fulfills National Flood Insurance Program (NFIP) insurance rating needs as well as floodplain management requirements.
