recommended by Doug that will be easier route since you will be complying
with the local code.
* By designing the building to resist for flood requires designing the
perimeter walls for hydrostatic pressure which is concenterated more at the
bottom of the "triangular pyramid" (hydrostatic profile on the wall)
exerting extra moment at the base of the shear walls. You'll have to design
the footing for excess tensile loads. If flood exceeds 100 yr max. during
service life than you are looking into re-eval of the footing and
connections at the base....Further the building has to be analyzed
completly for potential flood effects.
