The process required defining the program components, establishing a levee recognition policy for each one, and justifying the resulting recommendations. DIMENSIONS OF LEVEE RECOGNITION Flood loss mitigation is promoted through the following six basic measures or dimensions that are either direct requirements of or closely associated with the NFIP: 1.

From page 6... ...
The risk of levee failure varies with many characteristics, but the primary variable for purposes of levee recognition must be the flood frequency associated with overtopping. Other levee properties can logically be specified as minimum requirements for reducing structural levee failure to acceptably low levels.

From page 7... ...
Recommendations are specified for each element of the NFIP and associated with flood hazard mapping designations. For example, a 25-year levee is required before protected property becomes eligible for reduced insurance rates, whereas a 100-year levee is recognized as sufficient to lift requirements for elevation of residential structures and flood proofing of industrial and commercial structures.

It is technical differences in the degree of flood risk which determine whether lumping areas of differing hazard for administrative convenience violates concepts of equity. It is the degree of reliability in technical estimation that determines whether differences along the hazard continuum are significant before applying economic principles to formulate different policies.
