As the lot size increases beyond the one-half acre, the technical justification required for issuing the variance increases. Variances may be issued for the repair or rehabilitation of historic structures upon determination that: ---PAGE BREAK--- the proposed repair or rehabilitation will not preclude the structure's continued designation as a "Historic Structure". (ii) the variance is the minimum necessary to preserve the historic character and design of the structure. Variances may be issued by a community for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use provided that: the criteria of subparagraphs 1, 4, 5, and 6 of this Section are met; (ii) the structure or other development is protected by methods that minimize flood damages during the base flood and create no additional threat to public safety. Variances shall not he issued within any designated floodway if any increase in flood levels during the base flood discharge would result. Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. Variances shall only be issued upon receiving written justification of: a showing of good and sufficient cause; (ii) a determination that failure to grant the variance would result in exceptional hardship to the applicant; and (iii) a determination that the granting or 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. Any applicant to whom a variance is granted for a building with the lowest floor below the base flood elevation shall be given written notice over the signature of a community official that the cost of flood insurance will be commensurate with the increased risk resulting from lowest floor elevation. Be it enacted this 28th day of October 1992, by the Town Board, of the Town of Genoa, Cayuga County, New York, to be effective immediately.
