An existing structure in the Floodway may be substantially improved only:by variance; if the structure can be brought into conformance with this Division I without increasing its existing footprint; and if all residential uses of the structure are provided egress outside of the base flood. Substantial improvement of a nonconforming structure, regardless of location, may only be undertaken in compliance with this Division I and any other applicable law. In the event of substantial damage or proposed replacement, the applicant must submit an alternative analysis to determine if the structure can be relocated to a less hazardous site. Where replacement structures cannot be relocated, they must be limited to the footprint of the previous structure. Any replacement structure must meet all applicable requirements of this Division I. The modification, alteration, repair, reconstruction, or improvement of any nonconforming structure amounting to less than a substantial improvement must be elevated or floodproofed to the greatest extent possible. Uses or their adjuncts that are or become nuisances may not be permitted to continue.
