§ 151.10  CONDITIONS FOR VARIANCES.
   (A)   Generally, variances may be issued for new construction and substantial improvements to be erected on a lot of one-half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing divisions (B) through (E) below have been fully considered. As the lot size increases beyond the one-half acre, the technical justification required by issuing the variance increases.
   (B)   Variances may be issued for the repair or rehabilitation of historic structures upon a determination that the proposed repair or rehabilitation will not preclude the structure’s continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure.
   (C)   Variances shall only be issued on a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
   (D)   Variances shall only be issued upon:
      (1)   A showing of good and sufficient cause;
      (2)   A determination that failure to grant the variance would result in exceptional hardship to the applicant; and
      (3)   A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, cause fraud on or victimization of the public, or conflict with existing local laws or ordinances.
   (E)   Any applicant to whom a variance is granted shall be given a written notice that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest flood elevation.
