FEMA provides information about retrofitting and floodproofing structures to protect them from flooding and, in some cases, to lower flood insurance costs.
These actions are particularly recommended for properties that have turned in flood insurance claims valued at $1,000 or more at least twice in any 10 year period. These are called “repetitive loss” properties. Retrofitting and floodproofing can help break the cycle of repetitive flood damage.
Retrofitting:
Making changes to an existing building to protect it from flooding or other hazards.
Floodproofing:
A combination of structural and non-structural adjustments that allow non-residential buildings under construction or undergoing substantial improvement to have portions of the structure beneath the required base flood elevation. Floodproofing of areas below base flood elevation is not permitted in residential structures.
