A. In passing upon applications for variances from the provisions of
this Chapter, the Board of Adjustment shall consider all technical
data and evaluations, all relevant factors, standards specified in
other Sections of this Chapter, and the following criteria:
1.
The danger to life and property due to flood damage;
2.
The danger that materials may be swept onto other lands to the
injury of others;
3.
The susceptibility of the proposed structure 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 structure
to the City;
5.
The necessity to the structure of a waterfront location, where
applicable;
6.
The availability of alternative locations, not subject to flood
damage, for the proposed use;
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 requirements applicable to the property;
9.
The safety of access to the property in times of flood for ordinary
and emergency vehicles;
10.
The expected heights, velocity, duration, rate of rise and sediment
transport of the floodwaters, if applicable, expected at the property;

A. Generally, variances may be issued for new construction and substantial improvements 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, provided that Subsections
(B) through
(F) below have been fully considered. As the lot size increases beyond the one-half (1/2) acre, the technical justification required for issuing the variance increases.
B. Variances may be issued for the reconstruction, rehabilitation or
restoration of structures listed on the National Register of Historic
Places, the State Inventory of Historic Places or local inventory
of historic places provided that the proposed activity will not preclude
the structure's continued historic designation.
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, considering the flood hazard, to afford
relief.
E. Variances shall only be issued upon:
1.
Compliance with the requirements of Article
IV of Chapter
415 of the Municipal Code;
2.
A showing of good and sufficient cause;
3.
A determination that failure to grant the variance would result
in exceptional hardship to the applicant; and
4.
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, cause fraud on or victimization
of the public or conflict with existing local laws or ordinances.
F. The City shall notify the applicant in writing, over the signature
of the Floodplain Administrator, that:
1.
The issuance of a variance to construct a structure below 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
2.
Such construction below the base flood level increases risks
to life and property. Such notification shall be maintained with the
record of all variance actions as required by this Chapter.
[Ord. No. 1782 §1, 11-18-2015; Ord.
No. 2086, 2-17-2021]
A. A decision to grant any variance for an accessory structure shall be decided individually based on a case-by-case analysis of the accessory structure's unique circumstances. Variances granted shall meet the following conditions as well as those criteria and conditions set forth in Article
IV, Sections
415.190 and
415.200 of this Chapter.
B. In order to minimize flood damages and the threat to public health
and safety during the one percent (1%) flood, the following conditions
shall be included in any variance issued for accessory structures
that are constructed at-grade and floodproofed:
1.
Use of the accessory structure must be solely for parking and
limited storage purposes in Zone A only as identified on the City's
FIRM.
2.
For any new or substantially damaged accessory structure, the exterior and interior building components and elements (i.e., foundation, wall framing, exterior and interior finishes, flooring, etc.) below the base flood elevation must be built with flood-resistant materials in accordance with Article
III, Section
415.110(E)(2) of this Chapter.
3.
The accessory structure must be adequately anchored to prevent flotation, collapse or lateral movement of the structure in accordance with Article
III, Section
415.110(E)(1) of this Chapter. All of the building's structural components must be capable of resisting specific flood-related forces including hydrostatic, buoyancy, hydrodynamic and debris impact forces.
4.
Any mechanical, electrical or other utility equipment must be located above the base flood elevation or floodproofed so that they are contained within a watertight, floodproofed enclosure that is capable of resisting damage during flood conditions in accordance with Article
III, Section
415.110(E)(4) of this Chapter.
5.
The accessory structure must meet all NFIP opening requirements. The NFIP requires that enclosure or foundation walls, subject to the one percent (1%) flood, contain openings that will permit the automatic entry and exit of floodwaters in accordance with Article
III, Section
415.120(A)(3) of this Chapter.
6.
The accessory structures must comply with the floodplain management floodway encroachment provisions of Article
III, Section
415.140(A)(2) of this Chapter. No variances may be issued for accessory structures within any designated floodway, if any increase in flood levels would result during the one percent (1%) flood.
7.
Equipment, machinery or other contents must be protected from
any flood damage.
8.
No disaster relief assistance under any program administered
by any Federal agency shall be paid for any repair or restoration
costs of the accessory structures.

of the Floodplain Administrator that:
a.
The issuance of a variance to construct a structure below 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. Such notification shall be maintained with the
record of all variance actions as required by this Chapter.
10.
Wet-floodproofing construction techniques must be reviewed and
approved by the Floodplain Administrator and a registered professional
engineer or architect prior to the issuance of any floodplain development
permit for construction.
