If the requirements of Section 42-94(1) are adhered to and BFE data aze available from other sources, all new construction and substantial improvements within such areas shall also comply with all applicable provisions of this Ordinance and shall be elevated or flood proofed according to elevations established according to Section 42-69(11/12).

All new construction and substantial improvements of non-residential structures shall have the option, in lieu of elevation, to be completely flood proofed together with attendant utilities and sanitary facilities to or above that level so that any space below that level is watertight with walls substantially impermeable to the passage of water and with structural components having the capacity of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. Certification is required as per Section 42-68(3) and Section 42-92(2). (Ord. of 8-28-1995, § 5.5, eff. 8-28-1995) Sec. 42-96. Effect upon outstanding floodplain development permits.
