(6) The Board of Appeals shall maintain the records of all appeal actions including technical information and report any variances to the Federal Emergency Management Agency upon request. 6.2 CONDITIONS FOR VARIANCES (1) 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 the items in Section 6.1(4) have been fully considered. As the lot size increases beyond the one-half acre, the technical justification required for issuing the variance increases. (2) Variances may be issued for the reconstruction, rehabilitation or restoration of structures and contributing structures listed on the National Register of Historic Places or the State Inventory of Historic Places, without regard to the procedures set forth in the remainder of this section. (3) Variances may be issued for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use provided that: (a) the criteria of subparagraphs 1, 4, 5, and 6 of this section 6.2 are met; (b) 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. (4) Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. • (5) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. (6) Variances shall be issued only upon: (a) a showing of good and sufficient cause; (b) a determination that failure to grant the variance would result in exceptional 16 flood.!!, wp51,Danby, ,12/17/91 5:44pm hardship to the applicant; and (c) 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. (7) 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 that the cost of flood insurance will be commensurate with the increased risk resulting from lowest floor elevation. _ Section 2: If any provision of this local law is found invalid by any court of competent jurisdiction, such invalidity shall not affect any of the other provisions of this local law which shall remain in full force and effect. Section 3: This local law shall supersede any prior ordinances, laws, or provisions governing flood damage protection previously enacted by the Town of Danby, including particularly Local Law Number 4 for the year 1985.

As the lot size increases beyond the one-half acre, the technical justification required for issuing the variance increases. (2) Variances may be issued for the reconstruction, rehabilitation or restoration of structures and contributing structures listed on the National Register of Historic Places or the State Inventory of Historic Places, without regard to the procedures set forth in the remainder of this section. (3) Variances may be issued for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use provided that: (a) the criteria of subparagraphs 1, 4, 5, and 6 of this section 6.2 are met; (b) 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. (4) Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. (5) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. (6) Variances shall be issued only upon: (a) a showing of good and sufficient cause; (b) a determination that failure to grant the variance would result in exceptional hardship to the applicant; and (c) 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. (7) 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 that the cost of flood insurance will be commensurate with the increased risk resulting from lowest floor elevation. 16 flood.11, wp51,Danby, ,12/17/91 9:27pm Section 2: If any provision of this local law is found invalid by any court of competent jurisdiction, such invalidity shall not affect any of the other provisions of this local law which shall remain in full force and effect.

As the lot size increases beyond the one-half acre, the technical justification required for issuing the variance increases. (2) Variances may be issued for the reconstruction, rehabilitation or restoration of structures and contributing structures listed on the National Register of Historic Places or the State Inventory of Historic Places, without regard to the procedures set forth in the remainder of this section. (3) Variances may be issued for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use provided that: (a) the criteria of subparagraphs 1, 4, 5, and 6 of this section 6.2 are met; (b) 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. (4) Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. (5) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. (6) Variances shall be issued only upon: (a) a showing of good and sufficient cause; (b) a determination that failure to grant the variance would result in exceptional hardship to the applicant; and (c) 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. (7) 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 that the cost of flood insurance will be commensurate with the increased risk resulting from lowest floor elevation. 16 flood.!!, wp51,Danby, , 12/17/91 9:27pm Section 2: If any provision of this local law is found invalid by any court of competent jurisdiction, such invalidity shall not affect any of the other provisions of this local law which shall remain in full force and effect.
