The variance criteria set forth in this section are based on the general principle of zoning law that variances pertain to a piece of property and are not personal in nature. A variance may be granted for a parcel of property with physical characteristics so unusual that complying with the requirements of this chapter would create an exceptional hardship to the applicant or the surrounding property owners. The characteristics must be unique to the property and not be shared by adjacent parcels. The unique characteristic must pertain to the land itself, not to the structure, its inhabitants or the property owners.
It is the duty of the city to help protect its citizens from flooding. This need is so compelling and the implications of the cost of insuring a structure built below flood level are so serious that variances from the flood elevation or from other requirements in this chapter are quite rare.
A. Appeal Board:
1. The city council shall hear and decide requests for variances from the requirements of this chapter. In passing upon requests for variances, the city council shall consider all technical evaluations, all relevant factors, standards specified in other sections of this chapter, and:
a. Danger that materials may be swept onto other lands to the injury of others;
b. Danger to life and property due to flooding or erosion damage;
c. Susceptibility of the proposed facility and its contents to flood damage, and the effect of such damage on the existing individual owner and future owners of the property;
d. Importance of the services provided by the proposed facility to the community;
e. Necessity to the facility of a waterfront location, where applicable;
f. Availability of alternative locations for the proposed use which are not subject to flooding or erosion damage;
g. Compatibility of the proposed use with existing and anticipated development;
h. Relationship of the proposed use to the comprehensive plan and floodplain management program for that area;
i. Safety of access to the property in time of flood for ordinary and emergency vehicles;
j. Expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters expected at the site; and
k. Costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities such as sewer, gas, electrical and water system and streets and bridges.
2. Any applicant to whom a variance is granted shall be given written notice by the city that:
a. 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 ($25.00) for one hundred dollars ($100.00) of insurance coverage; and
b. Such construction below the base flood level increases risks to life and property. A copy of the notice shall be recorded by the floodplain administrator in the office of the county recorder.
3. The floodplain administrator will maintain a record of all variance actions, including justification for their issuance, and report such variances issued in its biennial report submitted to the federal insurance administration of the federal emergency management agency.
B. Conditions For Variances:
1. Generally, variances may be issued for new construction, substantial improvement and other proposed new development to be erected on a lot of one-half (1/2) 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 12-1-4 and 12-1-5 of this chapter have been fully considered. As the lot size increases beyond one-half (1/2) acre, the technical justification required for issuing the variance increases.
2. Variances may be issued for the repair or rehabilitation of an historic structure, as defined in section 12-1-2 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.
3. Variances shall not be issued within any mapped regulatory floodway if any increase in flood levels during the base flood discharge would result.
4. 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 of deviation from the requirements of this chapter. In the case of variances to an elevation requirement, this means the city 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 city believes will both provide relief and preserve the integrity of this chapter.
5. Variances shall only be issued upon:
a. Showing of good and sufficient cause;
b. Determination that failure to grant the variance would result in exceptional "hardship", as defined in section 12-1-2 of this chapter, to the applicant; and
c. Determination that the granting of a variance will not result in increased flood heights, additional threats to public safety or extraordinary public expense; create a nuisance 1 , cause fraud or victimization of the public, as defined in section 12-1-2 of this chapter, or conflict with existing local laws or ordinances.
6. 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 B1 through B5 of this section are satisfied and that the structure or other development is protected by methods that minimize flood damage during the base flood and does not result in additional threats to public safety and does not create a public nuisance.
7. Upon consideration of the factors of subsection A5 of this section and the purposes of this chapter, the city may attach such conditions to the granting of variances as it deems necessary to further the purposes of this chapter. (Ord. 95-001, 2-14-1995)
