Article 3. Floodplain Management
16-301 Statutory authorization.
The following floodplain management regulations, as written, were approved in draft form by the Chief Engineer of the Division of Water Resources of the Kansas Department of Agriculture on December 22, 2020.
The Legislature of the State of Kansas has in K.S.A. 12-741 et seq, and specifically in K.S.A. 12-766, delegated the responsibility to local governmental units to adopt floodplain management regulations designed to protect the health, safety, and general welfare of the public. Therefore, the City Council of the City of South Hutchinson, Kansas, ordains as follows:
(Ord. 01- 675, Sec. 1; Ord. 21-01)
16-302 Findings of fact.
The special flood hazard areas of South Hutchinson, Kansas, are subject to inundation which results 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.
These flood losses are caused by (1) the cumulative effect of development in any delineated floodplain causing increases in flood heights and velocities; and (2) the occupancy of flood hazard areas by uses vulnerable to floods, hazardous to others, inadequately elevated, or otherwise unprotected from flood damages.
The Flood Insurance Study (FIS) that is the basis of this article uses a standard engineering method of analyzing flood hazards, which consist of a series of interrelated steps.
(Ord. 01-675, Sec. 1; Ord. 21-01)
16-303 Statement of purpose.
It is the purpose of this article to promote the public health, safety, and general welfare; to minimize those losses described in section 16-302(a); to establish or maintain the community’s eligibility for participation in the National Flood Insurance Program (NFIP) as defined in 44 Code of Federal Regulations (CFR) § 59.22(a)(3);and to meet the requirements of 44 CFR § 60.3(d) and K.A.R. 5-44-4 by applying the provisions of this article to:
(Ord. 01-675, Sec. 1; Ord. 21-01)
16-304 General provisions; lands to which article applies.
This article shall apply to all lands within the jurisdiction of the City of South Hutchinson, in Reno County, Kansas identified as numbered and unnumbered A Zones, AE, AO and AH Zones on the Flood Insurance Rate Map (FIRM) panels referenced on the associated FIRM Index dated January 29, 2021 as amended, and any future revisions thereto. In all areas covered by this article, no development shall be permitted except through the issuance of a floodplain development permit, granted by the City Council or its duly designated representative under such safeguards and restrictions as the City Council or the designated representative may reasonably impose for the promotion and maintenance of the general welfare, health of the inhabitants of the community, and as specifically noted in sections 16-312:317.
(Ord. 01-675, Sec. 1; Ord. 21-01)
16-305 Same; compliance.
No development located within known flood hazard areas of this community shall be located, extended, converted or structurally altered without full compliance with the terms of this article and other applicable regulations.
(Ord. 01-675, Sec. 1)
16-306 Same; abrogation and greater restrictions.
It is not intended by this article to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this article imposes greater restrictions, the provisions of this article shall prevail. All other ordinances inconsistent with this article are hereby repealed to the extent of the inconsistency only.
(Ord. 01-675, Sec. 1; Ord. 21-01)
16-307 Same; interpretation.
In their interpretation and application, the provisions of this article 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 Kansas statutes.
(Ord. 01-675, Sec. 1)
16-308 Same; warning and disclaimer of liability.
The degree of flood protection required by this article is considered reasonable for regulatory purposes and is based on engineering and scientific methods of study. Larger floods may occur on rare occasions or the flood height may be increased by manmade or natural cases, such as ice jams and bridge openings restricted by debris. This article does not imply that areas outside floodway and floodway fringe district boundaries or land uses permitted within such districts will be free from flooding or flood damage. This article shall not create liability on the part of the city, any officer or employee thereof for any flood damages that may result from reliance on this article or any administrative decision lawfully made thereunder.

(Ord. 01-675, Sec. 1; Ord. 21-01)
16-312 Provisions for flood hazard reduction; general standards.
Storage of material or equipment may be allowed if not subject to major damage by floods, if firmly anchored to prevent flotation, or if readily removable from the area within the time available after a flood warning.
A structure, or the use of a structure or premises that was lawful before the passage or amendment of this article, but which is not in conformity with the provisions of this article, may be continued subject to the following conditions:
Structures used solely for parking and limited storage purposes, not attached to any other structure on the site, of limited investment value, and not larger than 400 square feet, may be constructed at-grade and wet-floodproofed provided there is no human habitation or occupancy of the structure; the structure is of single-wall design; the accessory structure meets the following floodplain management requirements; and a floodplain development permit has been issued. Wet-floodproofing is only allowed for small low cost structures.
Any permit granted for an accessory structure shall be decided individually based on a case by case analysis of the building’s unique circumstances. Permits shall meet the following conditions.
In order to minimize flood damages during the one percent annual chance flood event, also referred to as the 100-year flood and the threat to public health and safety, the following conditions shall be required for any permit issued for accessory structures that are constructed at-grade and wet-floodproofed:
All hazardous material storage and handling sites shall be located out of the special flood hazard area.
(Ord. 01-675, Sec. 1; Ord. 21-01)
16-313 Specific standards.
New construction or substantial improvements of any residential structures, including manufactured homes, shall have the lowest floor, including basement, elevated to or above one foot above the base flood elevation. The elevation of the lowest floor shall be certified by a licensed land surveyor.
New construction or substantial improvement of any commercial, industrial, or other non-residential structures, including manufactured homes, shall have the lowest floor, including basement, elevated to or above one foot above the base flood elevation or, together with attendant utility and sanitary facilities, be floodproofed so that below the base flood elevation the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capacity of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. A registered professional engineer or architect shall certify that the standard of this subsection are satisfied. The elevation of the lowest floor shall be certified by a licensed land surveyor. Such certification shall be provided to the official as set forth in section 16-310(b)(7)(8)(9).
Require, for all new construction and substantial-improvements, that fully enclosed areas below lowest floor used solely for parking of vehicles, building access, or storage in an area other than a basement and 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 flood waters. Designs for meeting this requirement must either be certified by a registered professional engineer or architect or meet or exceed the following minimum criteria:

The following provisions apply:
(Ord. 01-675, Sec. 1; Ord. 21-01)
16-316 Floodway.
Located within areas of special flood hazard established in section 16-304 are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of flood waters that carry debris and potential projectiles, the following provisions shall apply:
(Ord. 01-675, Sec. 1; Ord. 21-01)
16-317 Recreational vehicles.
Require that recreational vehicles placed on sites within all unnumbered and numbered A Zones, AE, AH and AO Zones on the community’s FIRM either:
*A recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick-disconnect type utilities and security devices, and has no permanently attached additions.
(Code 2002; Ord. 21-01)
