Non-residential buildings may be structurally flood-proofed (in lieu of elevation); provided, a registered professional engineer certifies that:
(A) Below the flood protection elevation, the structure and attendant utility facilities are water- tight and capable of resisting the effects of the base flood;
(B) The building design accounts for flood velocities, duration, rate of rise, hydrostatic and hydrodynamic forces, the effects of buoyancy and impact from debris and ice; and
(C) Flood-proofing measures will be operable without human intervention and without an outside source of electricity.
