A.    Generally, variances may be issued for new construction, substantial improvement and other proposed new development 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 that the procedures of Sections 15.52.120 through 15.52.220 of this chapter have been fully considered. As the lot size increases beyond one-half acre, the technical justification required for issuing the variance increases.

    B.    Variances may be issued for the repair or rehabilitation of "historic structures" (as defined in Section 15.52.050 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 designated 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" (as defined in Section 15.52.050 of this chapter), considering the flood hazard, to afford relief.

    E.    Variances shall only be issued upon:

    1.    A showing of good and sufficient cause;

    2.    A determination that failure to grant the variance would result in exceptional "hardship" (as defined in Section 15.52.050 of this chapter) to the applicant; and

    3.    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" (as defined in Section 15.52.050 of this chapter), cause "fraud or victimization" (as defined in Section 15.52.050 of this chapter) of the public, or conflict with existing local laws or ordinances.

    F.    Variances may be issued for new construction, substantial improvement and other proposed new development necessary for the conduct of a functionally dependent use; provided, that the provisions of subsections A through E of this section are satisfied and that the structure or other development is protected by methods that minimize flood damages during the base flood and create no additional threats to public safety.

    G.    Upon consideration of the factors of Section 15.52.240C and the purposes of this chapter, the city council may attach such conditions to the granting of variances as it deems necessary to further the purposes of this chapter. (Ord. 463 § 1 (part), 1991: prior code § 26-6.30)
