A structure or the use of a structure or premises which was lawful before the effective date of this chapter but which is not in conformity with the provisions of this chapter may be continued subject to the following conditions.
(A) No use shall be expanded, changed, enlarged or altered in a way which increases its nonconformity.
(B) An alteration within the inside dimensions of a nonconforming use or structure is permissible, provided it will not result in increasing the flood damage potential of that use or structure.
(C) The cost of all structural alterations or additions both inside and outside of a structure to any nonconforming structure over the life of the structure shall not exceed 50% of the market value of the structure unless the conditions of this section are satisfied. The cost of all structural alterations and additions constructed since the adoption of city’s initial floodplain controls must be calculated into today’s current cost which will include all costs such as construction materials and a reasonable cost placed on all manpower or labor. If the current cost of all previous and proposed alterations and additions exceeds 50% of the current market value of the structure, then the structure must meet the standards of § 151.20 for new structures.
(D) If any nonconforming use of a structure or land or nonconforming structure is destroyed by any means, including floods, to an extent of 50% or more of its market value at the time of destruction, it shall not be reconstructed except in conformance with the provisions of this chapter. The city may issue a permit for reconstruction if the use is located outside the floodway and, upon reconstruction, is adequately elevated on fill in conformity with the provisions of this chapter.
