Freeboard Requirements
Current Building Status:
Compatible Rule:
Recommended freeboard for your home is:
Freeboard is a factor of safety usually
expressed in feet above a flood level for
purposes of floodplain management.
"Freeboard" tends to compensate for the many
unknown factors that could contribute to
flood heights greater than the height
calculated for a selected size flood and
floodway conditions, such as wave action,
bridge openings, and the hydrological effect
of urbanization of the watershed.
Freeboard is not required by NFIP standards,
but communities are encouraged to adopt at
least a one-foot freeboard to account for
the one-foot rise built into the concept of
designating a floodway and the encroachment
requirements where floodways have not been
designated.
Freeboard results in significantly lower
flood insurance rates due to lower flood
risk.
