Elevation on piers consisting of dry stacked blocks is prohibited. 4r+ err► (4) Within Zone A, when no base flood elevation data are available, new and substantially improved manufactured homes shall be elevated such that the manufactured home chassis is supported by reinforced piers or other foundation elements of at least equivalent strength that are no less than 36 inches in height above the lowest adjacent grade and are securely anchored to an adequately anchored foun- dation system to resist flotation, collapse or lateral movement. Elevation on piers consisting of dry stacked blocks is prohibited. (5) Within Zone AO, the floor shall be elevated above the highest adjacent grade at least as high as the depth number specified on the Flood Insurance Rate Map enumerated in Section 3.2 (at least two feet if no depth number is specified).

SECTION 6.0 VARIANCE PROCEDURE 6.1 APPEALS BOARD (1) The Zoning Board of Appeals as established by the Town of wappinger shall hear and decide appeals and requests for variances from the requirements of this local law.

(4) In passing upon such applications, the Zoning Board of Appeals shall consider all technical evaluations, all relevant factors, standards specified in other sections of this local law and: 20 (i) the .danger that materials may be swept onto other lands to the injury of others; (ii) the danger to life and property due to flooding or erosion damage; (iii) the susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner; (iv) the importance of the services provided by the proposed facility to the community; I%WgW (v) the necessity to the facility of a waterfront location, where applicable; (vi) the availability of alternative locations for the proposed use which are not subject to flooding or erosion damage; (vii) the compatibility of the proposed use with existing and anticipated development; (viii) the relationship of the proposed use to the comprehen- sive plan and floodplain management program of that area; (ix) the safety of access to the property in times of flood for ordinary and emergency vehicles; (x) the costs to local governments and the dangers associated with conducting search and rescue operations during periods of flooding; (xi) the expected heights, velocity, duration, rate of rise and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site; and (xii) the costs of providing governmental services during and after flood conditions, including search and rescue operations, „ maintenance and repair of public utilities and facilities such as sewer, gas, electrical, and water systems and streets and bridges. (5) Upon consideration of the factors of Section 6.1(4) and the purposes of this local law, the Zoning Board of Ap,=aalc may attach such conditions to the granting of variances as it deems necessary to further the purposes of this local law.

As the lot size increases beyond the one-half acre, the technical .justi- fication required for issuing the variance increases. (2) Variances may be issued for the. repair or rehabilitation of historic structures upon determination that: �.► (i) the proposed repair or rehabilitation will not preclude the 1%W 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. (3) 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: (i) 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. (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 only be issued upon receiving written justification of: (i) 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 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. 22 (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 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 day of , 1995 by the Town Board of the Town of Wappinger Dutchess , County, York, to be effective upon adoption and as prescribed by Municipal Home. Rule Law.
