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.

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

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.
