In all areas of special flood hazard where an applicant wishes to establish a permitted use, he/she must conform to the following requirements when relevant:
(A) Encroachments. All encroachment, including fill, new construction and substantial improvements are prohibited unless permitted by the Kentucky Department of Natural Resources and certification by a registered professional engineer or architect is provided which demonstrates, beyond reasonable doubt, that said encroachments shall not result in an increase of more than a one-foot rise in flood levels during occurrence of the base flood discharge.
(B) Residential construction. New construction or substantial improvement of any residential structure shall have the lowest floor, including basement, elevated to or above base flood elevation.
(C) Nonresidential construction. New construction or substantial improvement of any commercial, industrial or other nonresidential structure shall either have the lowest floor, including basement, elevated to the level of the base flood elevation or together with attendant utility and sanitary facilities, be flood-proofed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. A registered professional engineer or architect shall certify that the standards of this subsection are satisfied.
