Section 8-98-1 – 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 of Belle Plaine 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.
3.) Statement of Purpose. It is the purpose of this Ordinance to protect and preserve the rights, privileges and property of the City of Belle Plaine 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 Section 8-91-1 (b) of this Ordinance with provisions designed to:
a.) 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.
b.) 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.
c.) Protect individuals from buying lands which may not be suited for intended purposes because of flood hazard.
d.) Assure that eligibility is maintained for property owners in the community to purchase flood insurance through the National Flood Insurance Program.
Section 8-98-2 – General Provisions
1.) Lands to Which Ordinance Apply. The provisions of this Ordinance shall apply to all lands within the jurisdiction of the City of Belle Plaine which are located within the boundaries of the Floodplain (Overlay) District as established in Section 8-91-3.
2.) Rules for Interpretation of Floodplain (Overlay) District. The boundaries of the Floodplain (Overlay) District areas shall be determined by scaling distances on the official Flood Insurance Rate Map. When an interpretation is needed as to the exact location of a boundary, the Zoning Administrator shall make the necessary interpretation. The Board of Adjustment shall hear and decide appeals when it is alleged that there is an error in any requirement, decision, or determination made by the Zoning Administrator in the enforcement or administration of this Ordinance.
3.) Compliance. No structure or land shall hereafter be used and no structure shall be located, extended, converted or structurally altered without full compliance with the terms of this Ordinance and other applicable regulations which apply to uses within the jurisdiction of this Ordinance.
4.) Abrogation and Greater Restrictions. It is not intended by this Ordinance to repeal, abrogate or impair any existing easements, covenants, or deed restrictions. However, where this Ordinance imposes greater restrictions, the provision of this Ordinance shall prevail. All other ordinances inconsistent with this Ordinance are hereby repealed to the extent of the inconsistency only.
5.) Interpretation. In their interpretation and application, the provisions of this Ordinance shall be held to be minimum requirements and shall be liberally construed in favor of the governing body and shall not be deemed a limitation or repeal of any other powers granted by State statutes.
6.) Warning and Disclaimer of Liability. The standards required by this Ordinance are considered reasonable for regulatory purposes. This Ordinance does not imply that areas outside the designated Floodplain (Overlay) District areas will be free from flooding or flood damages. This Ordinance shall not create liability on the part of the City of Belle Plaine or any officer or employee thereof for any flood damages that from reliance on this Ordinance or any administrative decision lawfully made thereunder.
7.) Severability. If any section, clause, provision or portion of this Ordinance is adjudged unconstitutional or invalid by a court of competent jurisdiction, the remainder of this Ordinance shall not be affected thereby.
Section 8-98-3 Establishment of Floodplain (Overlay) District. The areas within the jurisdiction of the City of Belle Plaine having special flood hazards are hereby designated as a Floodplain (Overlay) District and shall be subject to the standards of the Floodplain (Overlay) District (as well as those for the underlying zoning district). The Floodplain (Overlay) District boundaries shall be as shown on the Flood Insurance Rate Map (FIRM) for Benton County and Incorporated Areas, the City of Belle Plaine, Panels 395, 425 and 525, dated June 3, 2008.
Section 8-98-4 Standards for Floodplain (Overlay) District. All uses must be consistent with the need to minimize flood damage and meet the following applicable performance standards. Where 100-year flood elevations and floodway data have not been provided on the Flood Insurance Rate Map, the Iowa Department of Natural Resources shall be contacted to compute such data. The applicant will be responsible for providing the Department of Natural Resources with sufficient technical information to make such determination.

b.) All new and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the system as well as the discharge of effluent into flood waters. Wastewater treatment facilities (other than on-site systems) shall be provided with a level of flood protection equal to or greater than one (1) foot above the 100-year flood elevation.
c.) New or replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system. Water supply treatment facilities (other than on-site systems) shall be provided with a level of protection equal to or greater than one (1) foot above the 100-year flood elevation.
d.) Utilities such as gas or electrical systems shall be located and constructed to minimize or eliminate flood damage to the system and the risk associated with such flood damaged or impaired systems.
5.) Storage of materials and equipment that are flammable, explosive or injurious to human, animal or plant life is prohibited unless elevated a minimum of one (1) foot above the 100-year flood level. Other material and equipment must either be similarly elevated or (i) not be subject to major flood damage and be anchored to prevent movement due to flood waters or (ii) be readily removable from the area within the time available after flood warning.
6.) Flood control structural works such as levees, flood walls, etc. shall provide, at a minimum, protection from a 100-year flood with a minimum of 3 ft. of design freeboard and shall provide for adequate interior drainage. In addition, structural flood control works shall be approved by the Department of Natural Resources.
7.) Watercourse alterations or relocations must be designed to maintain the flood carrying capacity within the altered or relocated portion. In addition, such alterations or relocations must be approved by the Department of Natural Resources.
8.) Subdivisions (including factory-built home parks and subdivisions) shall be consistent with the need to minimize flood damages and shall have adequate drainage provided to reduce exposure to flood damage. Development associated with subdivision proposals (including the installation of public utilities) shall meet the applicable performance standards of this Ordinance. Subdivision proposals intended for residential use shall provide all lots with a means of access which will be passable by wheeled vehicles during the 100-year flood. Proposals for subdivisions greater than five (5) acres or fifty (50) lots (whichever is less) shall include 100-year flood elevation data for those areas located within the Floodplain (Overlay) District. See Section 8-91-5 © in current Belle Plaine ordinance. “J” in the model ordinance is the minimum required language. If you want to keep C. in the review section you may, but Section 8-91-5 c. does not “replace” this section.
9.) Accessory Structures
a.) Detached garages, sheds, and similar structures accessory to a residential use are exempt from the 100-year flood elevation requirements where the following criteria are satisfied.
(i) The structure shall not be used for human habitation.

(iii) Indication of the use or occupancy for which the proposed work is intended.
(iv) Elevation of the 100-year flood. Compare to “f. For developments involving more than 5 acres….” This is a minimum FEMA requirement, but Iowa requirements are more stringent and require the elevation of the 100-year flood for all development.
(v) Elevation (in relation to National Geodetic Vertical Datum) of the lowest floor (including basement) of buildings or of the level to which a building is to be floodproofed.
(vi) For buildings being improved or rebuilt, the estimated cost of improvements and market value of the building prior to the improvements.
(vii) Such other information as the Administrator deems reasonably necessary (e.g., drawings or a site plan) for the purpose of this Ordinance.
c.) Action on Permit Application – The Administrator shall, within a reasonable time, make a determination as to whether the proposed floodplain development meets the applicable standards of this Ordinance and shall 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 City Board of Adjustment.
d.) Construction and Use to be as Provided in Application and Plans – Floodplain Development Permits based 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 Ordinance. The applicant shall be required to submit certification by a professional engineer or land surveyor, as appropriate, registered in the State of Iowa, that the finished fill, building floor elevations, floodproofing, or other flood protection measures were accomplished in compliance with the provisions of this Ordinance, prior to the use or occupancy of any structure.
3. Variance IF a variance procedure that meets these requirements is detailed elsewhere in the City Code, when you submit your amended ordinance, just send along a copy of that section.
a.) The City Board of Adjustment may authorize upon request in specific cases such variances from the terms of this Ordinance that will not be contrary to the public interest where, owing to special conditions, a literal enforcement of the provisions of this Ordinance will result in unnecessary hardship. Variances granted must meet the following applicable standards.
(i) 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.
(ii) Variances shall only be granted upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
(iii) In cases where the variance involves a lower level of flood protection for buildings than what is ordinarily required by this Ordinance, 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.
b.) Factors Upon Which the Decision of the Board of Adjustment Shall be Based – In passing upon applications for Variances, the Board shall consider all relevant factors specified in other sections of this Ordinance and:
(i) The danger to life and property due to increased flood heights or velocities caused by encroachments.
(ii) The danger that materials may be swept on to other land or downstream to the injury of others.
(iii) The proposed water supply and sanitation systems and the ability of these systems to prevent disease, contamination and unsanitary conditions.
(iv) The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner.
(v) The importance of the services provided by the proposed facility to the City.
(vi) The requirements of the facility for a floodplain location.
(vii) The availability of alternative locations not subject to flooding for the proposed use.
(ix) The compatibility of the proposed use with existing development and development anticipated in the foreseeable future.
(x) The relationship of the proposed use to the comprehensive plan and floodplain management program for the area.
(xi) The safety of access to the property in times of flood for ordinary and emergency vehicles.
(xii) The expected heights, velocity, duration, rate of rise and sediment transport of the flood water expected at the site.
(xii) 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.
(xiii) Such other factors which are relevant to the purpose of this Ordinance.
c.) Conditions Attached to Variances – Upon consideration of the factors listed above, the Board of Adjustment may attach such conditions to the granting of variances as it deems necessary to further the purpose of this Ordinance. Such conditions may include, but not necessarily be limited to:
(i) Modification of waste disposal and water supply facilities.
(ii) Limitation of periods of use and operation.
(iii) Imposition of operational controls, sureties, and deed restrictions.
(iv) 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 Ordinance.
(v) Floodproofing measures.
