The director of the Department of Public Works is appointed the floodplain administrator to administer and implement this article and other appropriate sections of 44 CFR (National Flood Insurance Program regulations) pertaining to floodplain management.
(1966 Code, sec. 15½-44; 2001 Code, sec. 54-61; Ordinance 15-2012, sec. 1, adopted 3/20/12)
Duties and responsibilities of the floodplain administrator shall include, but not be limited to, the following:
(1) 
Maintain and hold open for public inspection all records pertaining to this article.
(2) 
Review permit applications to determine whether proposed building sites will be reasonably safe from flooding.
(3) 
Review, approve or deny all applications for development permits required by adoption of this article.
(4) 
Review permits for proposed development to ensure that all necessary permits have been obtained from those federal, state or local governmental agencies, including section 404 of the Federal Water Pollution Control Act Amendments of 1972 (33 USC 1344) from which prior approval is required.
(5) 
Make the necessary interpretation where interpretation is needed as to the exact location of the boundaries of the areas of special flood hazards (for example, where there appears to be a conflict between a mapped boundary and actual field conditions).
(6) 
Notify, in riverine situations, adjacent communities and the state coordinating agencies prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency.
(7) 
Ensure that the flood-carrying capacity within the altered or relocated portion of any watercourse is maintained.
(8) 
When base flood elevation data has not been provided in accordance with section 54-31, obtain, review and reasonably utilize any base flood elevation data and floodway data available from a federal, state or other source, in order to administer division 3 of this article.
(9) 
a. 
When a regulatory floodway has not been designated, the floodplain administrator must require that no new construction, substantial improvements, or other development, including fill, shall be permitted within Zones A1-30 and AE on the community’s flood insurance rate map unless it is demonstrated that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any point within the community.
b. 
Under the provisions of 44 CFR 65.12 of the National Flood Insurance Program regulations, a community may approve certain development in Zones A1-30, AE, AH on the community’s flood insurance rate map which increases the water surface elevation of the base flood by more than one foot, provided that the community first applies for a conditional flood insurance rate map revision through the Federal Emergency Management Agency.
(1966 Code, sec. 15½-45; 2001 Code, sec. 54-62; Ordinance 15-2012, sec. 1, adopted 3/20/12)
(a) 
Application for a floodplain development permit shall be presented to the floodplain administrator on forms furnished by him and include, but are not limited to, plans in duplicate drawn to scale showing the location, dimensions and elevation of proposed landscape alterations; existing and proposed structures; and the location of such in relation to areas of special flood hazard. Additionally, the following information is required:
(1) 
Elevation, in relation to mean sea level, of the lowest floor, including basement, of all new and substantially improved structures.
(2) 
Elevation, in relation to mean sea level, to which any nonresidential structure shall be floodproofed.
(3) 
A certificate from a registered professional engineer or architect that the nonresidential floodproofed structure shall meet the floodproofing criteria of section 54-92(2).
(4) 
Description of the extent to which any watercourse or natural drainage will be altered or relocated as a result of proposed development.
(5) 
Maintain a record of all such information in accordance with section 54-62(1).
(b) 
Approval or denial of a floodplain development permit by the floodplain administrator shall be based on all of the sections of this article and the following relevant factors:
(1) 
The danger to life and property due to flooding or erosion damage.
(2) 
The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner.
(3) 
The danger that materials may be swept onto other lands to the injury of others.
(4) 
The compatibility of the proposed use with existing and anticipated development.
(5) 
The safety of access to the property in times of flood for ordinary and emergency vehicles.
(6) 
The costs of providing governmental services during and after flood conditions, including maintenance and repair of streets and bridges, and public utilities and facilities such as sewer, gas, electrical and water systems.
(7) 
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.
(8) 
The necessity to the facility of a waterfront location, where applicable.
(9) 
The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use.
(10) 
The relationship of the proposed use to the comprehensive plan for that area.
(11) 
The effect of any additional fill or accumulative fill on the 100-year floodplain of the Wichita River. Compensatory storage may be required to offset proposed fill.
(c) 
Fees for a floodplain development permit shall be as provided by separate ordinance.
(1966 Code, sec. 15½-46; 2001 Code, sec. 54-64; Ordinance 15-2012, sec. 1, adopted 3/20/12)
(a) 
The Zoning Board of Adjustment shall hear and render judgment on requests for variances from the requirements of this article.
(b) 
The Zoning Board of Adjustment shall hear and render judgment on an appeal only when it is alleged there is an error in any requirement, decision or determination made by the floodplain administrator in the enforcement or administration of this article.
(c) 
Any person aggrieved by the decision of the Zoning Board of Adjustment may appeal such decision in the courts of competent jurisdiction.
(d) 
The floodplain administrator shall maintain a record of all actions involving an appeal and shall report variances to the Federal Emergency Management Agency upon request.
(e) 
Variances may be issued for the reconstruction, rehabilitation or restoration of structures listed on the National Register of Historic Places or the state inventory of historic places, without regard to the procedures set forth in the remainder of this article.
(f) 
Variances may be issued for new construction and substantial improvements to be erected on a lot one-half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing the relevant factors section 54-64(b) have been fully considered. As the lot size increases beyond one-half acre, the technical justification required for issuing the variance increases.
(g) 
Upon consideration of the factors noted in and the intent of this article, the Zoning Board of Adjustment may attach such conditions to the granting of variances as it deems necessary to further the purpose and objectives of this article in section 54-29.
(h) 
Variances shall not be issued within any designated floodway or floodplain if any increase in flood levels during the base flood discharge would result.
(i) 
Variances may be issued for the repair or rehabilitation of historic structures upon a determination that the proposed repair or rehabilitation will not preclude the structure’s continued designation as a historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure.
(j) 
Prerequisites for granting variances shall be as follows:
(1) 
Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.
(2) 
Variances shall only be issued upon:
a. 
Showing a good and sufficient cause;
b. 
A determination that failure to grant the variance would result in exceptional hardship to the applicant; and
c. 
A determination that the granting of a variance will not result in increased flood heights, additional threats to public safety or 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 written notice that the structure will be permitted to be built with the lowest floor elevation below the base flood elevation, and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation.
(k) 
Variances may be issued by the city for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use, provided that the criteria outlined in subsections (a) through (j) of this section are met and the structure or other development is protected by methods that minimize flood damages during the base flood and create no additional threats to public safety.
(l) 
Each application for a variance shall be accompanied by a variance application fee as set out in this zoning ordinance in Appendix B to this volume, as amended.
(1966 Code, sec. 15½-47; 2001 Code, sec. 54-65; Ordinance 15-2012, sec. 1, adopted 3/20/12)
If any individual, including any officer, agent or employee acting in behalf of any individual, firm, association or corporation, violates any section of this article within the corporate city limits, he shall be guilty of a misdemeanor and, upon conviction of such violation in the municipal court, he shall be fined as provided in section 1-14. Each day that such violation continues shall be a separate offense. Prosecution or conviction under this section shall never be a bar to any other remedy or relief for violations of this article.
