106.07     INTERPRETATION.  In their interpretation and application, the provisions of this chapter shall be held to be minimum requirements and shall be liberally construed in favor of the Council and shall not be deemed a limitation or repeal of any other powers granted by State statutes.

106.08     WARNING AND DISCLAIMER OF LIABILITY.  The standards required by this chapter are considered reasonable for regulatory purposes.  This chapter does not imply that areas outside the designated special flood hazard areas will be free from flooding or flood damages.  This chapter shall not create liability on the part of the City or any officer or employee thereof for any flood damages that result from reliance on this chapter or any administrative decision lawfully made thereunder.

106.09     FLOOD PLAIN MANAGEMENT STANDARDS.  All uses must be consistent with the need to minimize flood damage and shall meet the following applicable performance standards.  Where 100-year flood data has not been provided in the Flood Insurance Rate Map, the Department of Natural Resources shall be contacted to compute such data.

1.      All development within the special flood hazard areas shall:

a.       Be consistent with the need to minimize flood damage.

b.      Use construction methods and practices that will minimize flood damage.

c.       Use construction materials and utility equipment that are resistant to flood damage.

d.      Obtain all other necessary permits from Federal, State and local governmental agencies including approval when required from the Iowa Department of Natural Resources.

2.      Residential buildings.  All new or substantially improved residential structures shall have the lowest floor, including basement, elevated a minimum of one (1) foot above the 100-year flood level and extend at such elevation at least 18 feet beyond the limits of any structure erected thereon.  Alternate methods of elevating (such as piers) may be allowed, subject to favorable consideration by the City Council, where existing topography, street grades, or other factors preclude elevating by fill.  In such cases, the methods used must be adequate to support the structure as well as withstand the various forces and hazards associated with flooding.  All new residential structures shall be provided with a means of access which will be passable by wheeled vehicles during the 100-year flood.

3.      Nonresidential buildings.  All new or substantially improved nonresidential buildings shall have the lowest floor (including basement) elevated a minimum of one (1) foot above the 100-year flood level, or together with attendant utility and sanitary systems, be flood-proofed to such a level.  When flood proofing is utilized, a professional engineer registered in the State shall certify that the flood proofing methods used are adequate to withstand the flood depths, pressures, velocities, impact and uplift forces and other factors associated with the 100-year flood; and that the structure, below the 100-year flood level, is watertight with walls substantially impermeable to the passage of water.  A record of the certification indicating the specific elevation ( in relation to National Geodetic Vertical Datum) to which any structures are flood-proofed shall be maintained by the Administrator.

4.      All new and substantially improved structures:

A.     Fully enclosed areas below the “lowest floor” (not including basements) that are subject to flooding shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters.  Designs for meeting this requirement must either be certified by a registered professional engineer or meet or exceed the following minimum criteria: 

(1)      A minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding shall be provided.

(2)      The bottom of all openings shall be no higher than one foot above grade.

(3)      Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of floodwaters.

B.     New and substantially improved structures must be designed (or modified) and adequately anchored to prevent flotation, collapse or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy.

C.     New and substantially improved structures must be constructed with electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.

5.      Factory-built homes:

160.13    ACTION ON APPLICATION.  The Administrator shall, within a reasonable time, make a determination as to whether the proposed flood plain development meets the applicable standards of this chapter and shll approve or disapprove the application.  For disapprovals, the applicant shall be informed, in writing, of the specific reasons therefore.  The Administrator shall not issue permits for variances except as directed by the Council.

160.14    CONSTRUCTION AND USE TO BE AS PROVIDED IN APPLICATION AND PLANS.  Flood Plain Development Permits, issued on the basis of approved plans and applications, authorize only the use, arrangement, and construction set forth in such approved plans and applications and no other use, arrangement or construction.  Any use, arrangement, or construction at variance with that authorized shall be deemed a violation of this chapter.  The applicant shall be required to submit certification by a professional engineer or land surveyor, as appropriate, registered in the State, that the finished fill, building floor elevations, flood proofing, or other flood protection measures were accomplished in compliance with the provisions of this chapter, prior to the use or occupancy of any structure.

160.15    VARIANCES.  The Council 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:

1.      Cause.  Variances shall 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 fold 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 ordinance.

2.      Prohibited.  Variances shall not be issued within any designated floodway if any increase in flood levels during the 100-year 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.

3.      Required To Afford Relief.  Variances shall only be granted upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.

4.      Notice to Applicant.  In cases where the variance involves a lower level of flood protection for buildings 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 for $100 of insurance coverage and (ii) such construction increases risks to life and property.

160.16    FACTORS UPON WHICH THE DECISION TO GRANT VARIANCES SHALL BE BASED.  In passing upon applications for variances, the Council shall consider all relevant factors specified in other sections of this chapter and:

1.      The danger to life and property due to increased flood heights or velocities caused by encroachments.

2.      The danger that materials may be swept on to other lands or downstream to the injury of others.

3.      The proposed water supply and sanitation systems and the ability of these systems to prevent disease, contamination and unsanitary conditions.

4.      The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner.

5.      The importance of the services provided by the proposed facility to the community.

6.      The requirements of the facility for a flood plain location.

7.      The availability of alternative locations not subject to flooding for the proposed use.

8.      The compatibility of the proposed use with existing development and development anticipated in the foreseeable future.

9.      The relationship of the proposed use to the comprehensive plan and flood plain management program for the area.

10.  The safety of access to the property in times of flood for ordinary and emergency vehicles.

11.  The expected heights, velocity, duration, rate of rise and sediment tranport of the flood water expected at the site.

12.  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.

13.  Such other factors which are relevant to the purpose of this chapter.

160.17    CONDITIONS ATTACHED TO VARIANCES.  Upon consideration of the factors listed in Section 160.16, the Council 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:

1.      Modification of waste disposal and water supply facilities.

2.      Limitation of periods of use and operation.

3.      Imposition of operational controls, sureties, and deed restrictions.
