(b) Variances shall only be issued upon: (i) showing a good and sufficient cause; (ii) <br />a determination that failure to grant the variance would result in exceptional hardship <br />to the applicant, and (iii) a determination that the granting of a variance will not result <br />in increased flood heights, additional threats to public safety, extraordinary public <br />expense, create nuisances, cause fraud on or victimization of the public, or conflict <br />with existing local laws or ordinances. <br />(c) Any application to which a variance is granted shall be given written notice that <br />the structure will be permitted to be built with the lowest floor elevation below the <br />base flood elevation, and that the cost of flood insurance will be commensurate with <br />the increased risk resulting from the reduced lowest floor elevation. <br />(11) Variances may be issued by a community for new construction and substantial <br />improvements and for other development necessary for the conduct of a functionally <br />dependent use provided that (i) the criteria outlined in section 94-65(1)—(9) are met, and (ii) <br />the structure or other development is protected by methods that minimize flood damages <br />during the base flood and create no additional threats to public safety. <br />Secs. 94-66-94-85. - Reserved. <br />DIVISION 3. - STANDARDS <br />Sec. 94-86. - General standards. <br />In all areas of special flood hazards and moderate flood hazards the following provisions are <br />required for all new construction and substantial improvements: <br />(1) All new construction or substantial improvements shall be designed (or modified) and <br />adequately anchored to prevent flotation, collapse or lateral movement of the structure <br />resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy; <br />(2) All new construction or substantial improvements shall be constructed by methods and <br />practices that minimize flood damage; <br />(3) All new construction or substantial improvements shall be constructed with materials <br />resistant to flood damage; <br />(4) All residential new construction or substantial improvements shall be constructed with <br />electrical, heating, ventilation, plumbing, and air conditioning equipment and other service <br />facilities that are designed to be elevated at least one foot above the base flood elevation, <br />or at or above the riverine 500-year floodplain elevation, whichever is higher, so as to prevent <br />water from entering or accumulating within the components during conditions of flooding; <br />(5) All new and replacement water supply systems shall be designed to minimize or eliminate <br />infiltration of flood waters into the system; <br />12 <br />
