(a) The overall objective for dry floodproofing shall be to provide the same relative level of flood protection for the structure, and the safety of its inhabitants, as would be derived by siting the lowest floor, including basement floor, at an elevation not less than the regulatory flood protection elevation.
(b) The collective benefits arising from the proposed flood protection measures must ensure that the following conditions are fully satisfied under base flood situations:
(1) The structure, its supporting foundations and all appurtenances thereto shall have both the structural strength and those flood protection measures necessary to fully resist the combined static and dynamic stresses engendered by the flood, and survive these stresses in an undamaged condition.
(2) Flood waters and waste water backup shall be completely excluded from the interior of the structure.
