14.04.770 Variances for special flood hazard areas.
A. 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 article 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.
B. It is the duty of the city of Bothell to help protect its citizens from flooding. This need is so compelling and the implications of the cost of insuring a structure built below the base flood elevation are so serious that variances from the flood elevation or from other requirements in the flood ordinance are quite rare. The long-term goal of preventing and reducing flood loss and damage can only be met if variances are strictly limited. Therefore, the variance guidelines provided in this section are more detailed and contain multiple provisions that must be met before a variance can be properly granted. The criteria are designed to screen out those situations in which alternatives other than a variance are more appropriate.
C. Variances shall only be issued:
1. Upon the following determinations:
a. 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; and
b. That the variance is the minimum necessary, considering the flood hazard, to afford relief; and
c. That there is a showing of good and sufficient cause; and
d. That failure to grant the variance would result in exceptional hardship to the applicant.
2. For a functionally dependent use, upon a determination that subsections (C)(1)(a) through (C)(1)(c) of this section are satisfied.
3. For the repair, rehabilitation, or restoration of historic structures, upon a determination that the proposed repair or rehabilitation will not preclude the structure’s continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure.
D. Variances shall not be issued within any floodway if any increase in flood levels during the base flood discharge would result.
E. Generally, variances may be issued for new construction and substantial improvements 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 BFE, provided the procedures of BMC 14.04.720 and 14.04.760 have been fully considered. As the lot size increases beyond one-half acre, the technical justification required for issuing the variance increases.
F. Variance Criteria. In considering variance applications, the city of Bothell shall consider all technical evaluations, all relevant factors, all standards specified in other sections of this chapter, and:
1. The danger that materials may be swept onto other lands to the injury of others;
2. The danger to life and property due to flooding or erosion damage;
3. The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;
4. The importance of the services provided by the proposed facility to the community;
5. The necessity to the facility of a waterfront location, where applicable;
6. The availability of alternative locations for the proposed use, which are not subject to flooding or erosion damage;
7. The compatibility of the proposed use with existing and anticipated development;
8. The relationship of the proposed use to the comprehensive plan and floodplain management program for that area;
9. The safety of access to the property in time of flood for ordinary and emergency vehicles;
10. The expected heights, velocity, duration, rate of rise, and sediment transport of the floodwaters expected at the site; and
11. The costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities, such as sewer, gas, electrical, water system, and streets and bridges.
G. Additional Requirements for Issuance of a Variance.
1. Any applicant to whom a variance is granted shall be given written notice over the signature of a community official that:
a. The issuance of a variance to construct a structure below the BFE will result in increased premium rates for flood insurance, up to amounts as high as $25.00 for $100.00 of insurance coverage; and
b. Such construction below the BFE increases risks to life and property.
2. The floodplain administrator shall maintain a record of all variance actions, including justification for their issuance.
3. The floodplain administrator shall condition the variance as needed to ensure that the requirements and criteria of this chapter are met. (Ord. 2315 § 19, 2020).
