(A) No increase in degree of nonconformity. No such use shall be expanded, changed, enlarged, or altered in a way that increases its nonconformity.
(B) Structural alterations or additions. Any structural alteration or addition to a nonconforming structure or nonconforming use that would result in increasing the flood damage potential of that structure or use shall be elevated on fill to the regulatory flood protection elevation in accordance with this chapter.
(C) Substantially damaged structures. If any nonconforming use or structure is substantially damaged, as defined in this chapter, it shall not be reconstructed except in conformity with the provisions of this chapter. The applicable provisions for establishing new uses or new structures will apply, depending upon whether the use or structure is in the floodway or flood fringe area.
(D) Substantial improvements. If a substantial improvement occurs, as defined in this chapter, from any combination of a building addition to the outside dimensions of the existing building or a rehabilitation, reconstruction, alteration, or other improvement to the inside dimensions of an existing nonconforming building, then the building addition and the existing nonconforming building must meet the requirements of this chapter for new structures, depending upon whether the structure is in the floodway or flood fringe area. If a substantial improvement occurs only from a building addition, then the building addition must meet the elevation on fill requirements for new structures, and the existing structure must also meet the elevation on fill requirements for new structures if any alteration is made to the common wall in excess of installing a standard doorway.
