Freeboard: A Comprehensive Guide to Its Legal Definition and Role

Definition & Meaning

Freeboard refers to a safety margin, typically measured in feet, that is added above a designated flood level for floodplain management purposes. This additional height is intended to account for various unpredictable factors that could cause floodwaters to rise higher than expected. These factors may include wave action, the design of bridge openings, and the impact of urban development on water flow in the surrounding area.

Real-world examples

Here are a couple of examples of abatement:

For instance, a new residential building in a flood zone may be required to have a freeboard of two feet above the base flood elevation to ensure safety. This means if the base flood elevation is 10 feet, the building's lowest floor must be at least 12 feet above sea level.

(Hypothetical example) A city planning to develop a new park along a river may need to consider freeboard in its design to prevent future flooding impacts on recreational areas.

State-by-state differences

State Freeboard Requirement
California Minimum of one foot above base flood elevation
Florida Minimum of two feet above base flood elevation
Texas Varies by municipality; often one to two feet

This is not a complete list. State laws vary, and users should consult local rules for specific guidance.
