City relating to this Chapter may appeal to the Board of Adjustment
within sixty (60) days of the application of such order, requirement,
decision or determination. An application to appeal must be filed
with the City Clerk specifying the grounds for appeal within sixty
(60) days of the order, requirement, decision or determination appealed
from.
2. The City Clerk shall submit such application to the Planning Commission
at its next regularly scheduled meeting. The Planning Commission shall
review the application and make its recommendations to the Board of
Adjustment within a reasonable time, not to exceed sixty (60) days
from the date of referral to the Planning Commission.
3. The Board of Adjustment shall hear and decide appeals within a reasonable
time period, not to exceed sixty (60) days from the date it receives
the recommendations of the Planning Commission.
4. The Board of Adjustment shall give at least fifteen (15) days' public
notice of its hearing on each appeal in a newspaper of general circulation
in the City. The Board of Adjustment shall also give due notice to
interested parties, including the appellant and persons owning property
located within three hundred (300) feet of the property which is the
subject of the appeal. Any interested party may appear at the hearing
of the Board of Adjustment on an appeal in person or by attorney.
5. After public hearing on any appeal from any order, requirement, decision
or determination of the Director or other administrative official
or on a request for a variance, the Board of Adjustment may reverse,
affirm or modify, in whole or in part, the order, requirement, decision
or determination of the Director or other administrative official.
The concurring vote of four (4) members of the Board of Adjustment
shall be necessary to reverse or modify any order, requirement, decision
or determination of the Director or other administrative official
or to grant a variance in accordance with this Chapter.
E. In
passing upon such applications, the Board of Adjustment shall consider
all technical evaluations, relevant factors, standards specified in
other Sections of this Chapter and the following:
1. The danger that materials may be swept onto other lands to the injury
of others;
2. The danger of life and property due to flooding, stormwater or erosion
damage;
3. The susceptibility of the proposed facility and its contents to flood,
stormwater or erosion 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 availability of alternative locations for the proposed use, not
subject to flooding, stormwater or erosion damage; or alternative
designs of the building;
6. The compatibility of the proposed use with existing and anticipated
development;
7. The relationship of the proposed use to the Zoning Code of the City
and the floodplain management program for that area;
8. The safety of access to the property in times of flood for ordinary
and emergency vehicles;
9. The expected heights, velocity, duration, rate of rise and sediment
transport of the floodwaters and the effects of wave action, if applicable,
expected at the site; and
10. The general expected or relative 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 systems and streets and bridges.
F. Generally, variances from the flood control regulations set forth in Article
II herein may be issued for new construction and substantial improvements to be erected on a lot of one-half (½) acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing Subsections
(E)(1) through
(10) of this Section have been fully considered. As the parcel size increases beyond one-half (½) acre, the technical justification required for issuing any variance increases and the Board of Adjustment may require submission of additional data and preparation of alternative plans.
G. Variances from the flood control regulations set forth in Article
II herein shall not be issued within any designated floodway which would increase flood levels during the base flood more than one (1) foot at any point.
H. The
following prerequisites for the issuance of a variance shall be in
effect:
1. Variances shall only be issued upon a determination that the variance
is the minimum necessary to afford relief.
2. Variances shall only be issued upon:
a. A showing of good and sufficient cause that specific enforcement
would result in unnecessary hardship.
b. 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.
3. Any applicant to whom a variance is granted shall be given a written
notice that the cost of flood insurance will be commensurate with
the increased risk resulting from the reduced lowest floor elevation.
4. The Director or his/her designee shall maintain the records of all
appeal actions and report any variances to the Federal Insurance Administration
upon request.
