160.02 STATUTORY AUTHORITY, FINDINGS OF FACT AND PURPOSE.
1. The Legislature of the State of Iowa has in Chapter 414, Code of Iowa, as amended, delegated the power to cities to enact zoning regulations to secure safety from flood and to promote health and the general welfare.
2. Findings of Fact.
A. The flood hazard areas of the City are subject to periodic inundation which can result in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base all of which adversely affect the public health, safety and general welfare of the community.
B. These flood losses, hazards, and related adverse effects are caused by: (i) the occupancy of flood hazard areas by uses vulnerable to flood damages which create hazardous conditions as a result of being inadequately elevated or otherwise protected from flooding; and (ii) the cumulative effect of obstructions on the floodplain causing increases in flood heights and velocities.
C. This chapter relies upon engineering methodology for analyzing flood hazards which is consistent with the standards established by the Department of Natural Resources.
3. Statement of Purpose. It is the purpose of this chapter to protect and preserve the rights, privileges, and property of the City and its residents and to preserve and improve the peace, safety, health, welfare, and comfort and convenience of its residents by minimizing those flood losses described in Paragraph 2(A) of this section with provisions designed to:
A. Reserve sufficient floodplain area for the conveyance of flood flows so that flood heights and velocities will not be increased substantially.
B. Restrict or prohibit uses which are dangerous to health, safety, or property in times of flood or which cause excessive increases in flood heights or velocities.
C. Require that uses vulnerable to floods, including public facilities which serve such uses, be protected against flood damage at the time of initial construction or substantial improvement.
D. Protect individuals from buying lands which may not be suited for intended purposes because of flood hazard.
E. Assure that eligibility is maintained for property owners in the community to purchase flood insurance through the National Flood Insurance Program.

The official from whom the appeal is taken shall transmit to the Board all the documents constituting the record upon which the action appealed from was taken.
2. Variance. The Board may authorize upon request in specific cases such variances from the terms of this chapter that will not be contrary to the public interest where, owing to special conditions, a literal enforcement of the provisions of this chapter will result in unnecessary hardship. Variances granted must meet the following applicable standards.
A. Variances shall only be granted upon: (i) a showing of good and sufficient cause; (ii) a determination that failure to grant the variance would result in exceptional hardship to the applicant; and (iii) a determination that the granting of the 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 codes or ordinances.
B. Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood would result. Consideration of the effects of any development on flood levels shall be based upon the assumption that an equal degree of development would be allowed for similarly situated lands.
C. Variances shall only be granted upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
D. In cases where the variance involves a lower level of flood protection for structures than what is ordinarily required by this chapter, the applicant shall be notified in writing over the signature of the Administrator that: (i) the issuance of a variance will result in increased premium rates for flood insurance up to amounts as high as $25.00 for $100.00 of insurance coverage; and (ii) such construction increases risks to life and property.
E. All variances granted shall have the concurrence or approval of the Department of Natural Resources.
3. Hearings and Decisions of the Board.
A. Hearings. Upon the filing with the Board of an appeal or a request for a variance, the Board shall hold a public hearing. The Board shall fix a reasonable time for the hearing and give public notice thereof, as well as due notice to parties in interest. At the hearing, any party may appear in person or by agent or attorney and present written or oral evidence. The Board may require the appellant or applicant to provide such information as is reasonably deemed necessary and may request the technical assistance and/or evaluation of a professional engineer or other expert person or agency, including the Department of Natural Resources.
B. Decisions. The Board shall arrive at a decision on an appeal or variance within a reasonable time. In passing upon an appeal, the Board may, so long as such action is in conformity with the provisions of this chapter, reverse or affirm, wholly or in part, or modify the order, requirement, decision, or determination appealed from, and it shall make its decision, in writing, setting forth the findings of fact and the reasons for its decision. In granting a variance, the Board shall consider such factors as contained in this section and all other relevant sections of this chapter and may prescribe such conditions as contained in Subparagraph (2) of this paragraph.
(1) Factors Upon Which the Decision of the Board Shall Be Based. In passing upon applications for variances, the Board shall consider all relevant factors specified in other sections of this chapter and:
a. The danger to life and property due to increased flood heights or velocities caused by encroachments.
b. The danger that materials may be swept on to other land or downstream to the injury of others.
c. The proposed water supply and sanitation systems and the ability of these systems to prevent disease, contamination, and unsanitary conditions.
d. The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner.
e. The importance of the services provided by the proposed facility to the City.
f. The requirements of the facility for a floodplain location.
g. The availability of alternative locations not subject to flooding for the proposed use.
h. The compatibility of the proposed use with existing development and development anticipated in the foreseeable future.
i. The relationship of the proposed use to the comprehensive plan and floodplain management program for the area.
j. The safety of access to the property in times of flood for ordinary and emergency vehicles.
k. The expected heights, velocity, duration, rate of rise and sediment transport of the flood water expected at the site.
l. The cost of providing governmental services during and after flood conditions, including maintenance and repair of public utilities (sewer, gas, electrical, and water systems), facilities, streets, and bridges.
m. Such other factors which are relevant to the purpose of this chapter.
(2) Conditions Attached to Variances. Upon consideration of the factors listed above, the Board may attach such conditions to the granting of variances as it deems necessary to further the purpose of this chapter. Such conditions may include, but not necessarily be limited to:
a. Modification of waste disposal and water supply facilities.
b. Limitation of periods of use and operation.
c. Imposition of operational controls, sureties, and deed restrictions.
d. Requirements for construction of channel modifications, dikes, levees, and other protective measures, provided such are approved by the Department of Natural Resources and are deemed the only practical alternative to achieving the purpose of this chapter.
e. Floodproofing measures shall be designed consistent with the flood protection elevation for the particular area, flood velocities, duration, rate of rise, hydrostatic and hydrodynamic forces, and other factors associated with the regulatory flood. The Board shall require that the applicant submit a plan or document certified by a registered professional engineer that the floodproofing measures are consistent with the regulatory flood protection elevation and associated flood factors for the particular area.
4. Appeals to the Court. Any person or persons, jointly or severally, aggrieved by any decision of the Board may present to a court of record a petition, duly verified, setting forth that such decision is illegal, in whole or in part, specifying the grounds of the illegality. Such petition shall be presented to the court within thirty days after the filing of the decision in the office of the Board.
160.09 NONCONFORMING USES. A structure or the use of a structure or premises which was lawful before the passage or amendment of the ordinance codified in this chapter, but which is not in conformity with the provisions of this chapter, may be continued subject to the following conditions:
1. If such use is discontinued for six consecutive months, any future use of the building premises shall conform to this chapter.
2. Uses or adjuncts thereof that are or become nuisances shall not be entitled to continue as nonconforming uses.
3. If any nonconforming use or structure is destroyed by any means, including flood, it shall not be reconstructed if the cost is more than 50 percent of the market value of the structure before the damage occurred, unless it is reconstructed in conformity with the provisions of this chapter. This limitation does not include the cost of any alteration to comply with existing state or local health, sanitary, building or safety codes or regulations or the cost of any alteration of a structure listed on the National Register of Historic Places, provided that the alteration shall not preclude its continued designation
Except as provided in Subsection 2 of this section, any use which has been permitted as a variance shall be considered a conforming use.
160.11 PENALTIES FOR VIOLATION. Violations of the provisions of this chapter or failure to comply with any of the requirements (including violations of conditions and safeguards established in connection with grants of variances) shall constitute a misdemeanor. Any person who violates this chapter or fails to comply with any of its requirements shall upon conviction thereof be fined not more than $(500.00) or imprisoned for not more than (30) days. Each day such violation continues shall be considered a separate offense. Nothing herein contained prevent the City from taking such other lawful action as is necessary to prevent or remedy violation.
160.12 AMENDMENTS. The regulations and standards set forth in this chapter may from time to time be amended, supplemented, changed, or repealed. No amendment, supplement, change, or modification shall be undertaken without prior approval of the Department of Natural Resources.
Section 2. Repealer. All ordinances or parts of ordinances in conflict with the provisions of this ordinance are hereby repealed.
Section 3. Effective Date. This ordinance shall be in effect from and after its final passage, approval and publication as provided by law.
