(a) Generally, variances may be issued in the discretion of the Floodplain Administrator for new construction, substantial improvement, and other proposed new development to be erected on a lot of one-half (0.5) acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing that the procedures of Articles 4 and 5 of this chapter have been fully considered. As the lot size increases beyond one-half (0.5) acre, the technical justification required for issuing the variance increases.
(b) Variances may be issued in the discretion of the Floodplain Administrator for the repair or rehabilitation of “historic structures” (as defined in Section 8-4.201 of this chapter) upon a determination that the proposed repair or rehabilitation will not preclude the structure’s continued designation as an historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure.
(c) Variances shall not be issued within any mapped regulatory floodway if any increase in flood levels during the base flood discharge would result.
(d) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. “Minimum necessary” means to afford relief with a minimum deviation from the requirements of this ordinance. For example, in the case of variances to an elevation requirement, this means that the Floodplain Administrator need not grant permission for the applicant to build at grade, or even to whatever elevation the applicant proposes, but only to that elevation which the Floodplain Administrator believes will both provide relief and preserve the integrity of the local ordinance.
(e) Any applicant to whom a variance is granted shall be given written notice over the signature of the Floodplain Administrator that:
(1) The issuance of a variance to construct a structure below the base flood level will result in increased premium rates for flood insurance up to amounts as high as twenty-five dollars ($25) for each one hundred dollars ($100) of insurance coverage, and
(2) Such construction below the base flood level increases risk to life and property. A copy of the notice shall be recorded by the Floodplain Administrator in the Office of the Yolo County Recorder and shall be recorded in a manner so that it appears in the chain of title of the affected parcel of land.
(f) The Floodplain Administrator shall maintain the records of variance actions, including justification for their issuance, and report such variances issued in its biennial report submitted to the Federal Emergency Management Agency.
