Article 5. Flood Plain Management

16-501. Statutory authorization, findings of fact, and purposes.

(a) STATUTORY AUTHORIZATION

(1) Approval of Draft Ordinance by Kansas Chief Engineer Prior to Adoption

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 September 19, 2016.

(2) Kansas Statutory Authorization

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. Therefore, the Mount Hope City Council of Mount Hope, Kansas, ordains as follows:

(b) FINDINGS OF FACT

(1) Flood Losses Resulting from Periodic Inundation

The special flood hazard areas of Mount Hope, 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.

(2) General Causes of the Flood Losses

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.

(3) Methods Used To Analyze Flood Hazards

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.

(A) Selection of a base flood that is based upon engineering calculations, which permit a consideration of such flood factors as its expected frequency of occurrence, the area inundated, and the depth of inundation. The base flood selected for this article is representative of large floods, which are characteristic of what can be expected to occur on the particular streams subject to this article. The base flood is the flood that is estimated to have a one percent chance of being equaled or exceeded in any one year as delineated on the Federal Insurance Administrator’s FIS, and illustrative materials dated December 22, 2016 as amended, and any future revisions thereto.

(B) Calculation of water surface profiles that are based on a standard hydraulic engineering analysis of the capacity of the stream channel and overbank areas to convey the regulatory flood.

(C) Computation of a floodway required to convey this flood without increasing flood heights more than one (1) foot at any point.

(D) Delineation of floodway encroachment lines within which no development is permitted that would cause any increase in flood height.

(E) Delineation of floodway fringe, i.e., that area outside the floodway encroachment lines, but still subject to inundation by the base flood.

It is the purpose of this article to promote the public health, safety, and general welfare; to minimize those losses described in subsection (b)(1); 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:

(1) Restrict or prohibit uses that are dangerous to health, safety, or property in times of flooding or cause undue increases in flood heights or velocities;

(2) Require uses vulnerable to floods, including public facilities that serve such uses, be provided with flood protection at the time of initial construction; and

(3) Protect individuals from buying lands that are unsuited for the intended development purposes due to the flood hazard.

(Ord. 323-2016)

16-502. General provisions.

(a) LANDS TO WHICH ORDINANCE APPLIES

This article shall apply to all lands within the jurisdiction Mount Hope identified as numbered and unnumbered A Zones, AE, AO, and AH Zones, on the Index Map dated December 22, 2016 of the Flood Insurance Rate Map (FIRM) 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 Mount Hope City Council or its duly designated representative under such safeguards and restrictions as the Mount Hope 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 Section 16-504.

(b) COMPLIANCE

No development located within the special 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.

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.

(d) INTERPRETATION

In their interpretation and application, the provisions of this article shall be held to be minimum requirements, 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.

(e) 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 heights may be increased by man-made or natural causes, such as ice jams and bridge openings restricted by debris. This article does not imply that areas outside the floodway and flood fringe or land uses permitted within such areas will be free from flooding or flood damage. This article shall not create a liability on the part of Mount Hope, any officer or employee thereof, for any flood damages that may result from reliance on this article or any administrative decision lawfully made there under.

(f) SEVERABILITY

If any section; clause; provision; or portion of this article is adjudged unconstitutional or invalid by a court of appropriate jurisdiction, the remainder of this article shall not be affected thereby.

(Ord. 323-2016)

16-504. Provisions for flood hazard reduction.

(a) GENERAL STANDARDS

(1) No permit for floodplain development shall be granted for new construction, substantial-improvements, and other improvements, including the placement of manufactured homes, within any numbered or unnumbered A zones, AE, AO, and AH zones, unless the conditions of this section are satisfied.

(2) All areas identified as unnumbered A zones on the FIRM are subject to inundation of the 100-year flood; however, the base flood elevation is not provided. Development within unnumbered A zones is subject to all provisions of this article. If Flood Insurance Study data is not available, the community shall obtain, review, and reasonably utilize any base flood elevation or floodway data currently available from Federal, State, or other sources.

(3) Until a floodway is designated, no new construction, substantial improvements, or other development, including fill, shall be permitted within any unnumbered or numbered A zones, or AE zones on the FIRM, 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.

(4) All new construction, subdivision proposals, substantial-improvements, prefabricated structures, placement of manufactured homes, and other developments shall require:

(A) Design or adequate anchorage to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy;

(B) Construction with materials resistant to flood damage;

(D) All electrical, heating, ventilation, plumbing, air-conditioning equipment, and other service facilities be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding;

(E) New or replacement water supply systems and/or sanitary sewage systems be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters, and on-site waste disposal systems be located so as to avoid impairment or contamination from them during flooding; and

(F) Subdivision proposals and other proposed new development, including manufactured home parks or subdivisions, located within special flood hazard areas are required to assure that:

(i) All such proposals are consistent with the need to minimize flood damage;

(ii) All public utilities and facilities, such as sewer, gas, electrical, and water systems are located and constructed to minimize or eliminate flood damage;

(iii) Adequate drainage is provided so as to reduce exposure to flood hazards; and

(iv) All proposals for development, including proposals for manufactured home parks and subdivisions, of greater than five (5) acres or fifty (50) lots, whichever is lesser, include within such proposals base flood elevation data.

(5) Storage, Material, and Equipment

(A) The 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.

(6) Nonconforming Use

A structure, or the use of a structure or premises that was lawful before the passage or amendment of the ordinance, but which is not in conformity with the provisions of this article, may be continued subject to the following conditions:

(A) If such structure, use, or utility service is discontinued for 6 consecutive months, any future use of the building shall conform to this article.

(B) If any nonconforming use or structure is destroyed by any means, including flood, it shall not be reconstructed if the cost is more than fifty (50) percent of the pre-damaged market value of the structure. This limitation does not include the cost of any alteration to comply with existing state or local health, sanitary, building, safety codes, regulations or the cost of any alteration of a structure listed on the National Register of Historic Places, the State Inventory of Historic Places, or local inventory of historic places upon determination.

(b) SPECIFIC STANDARDS

(1) In all areas identified as numbered and unnumbered A zones, AE, and AH Zones, where base flood elevation data have been provided, as set forth in Section 16-504(a)(2), the following provisions are required:

(A) Residential Construction

New construction or substantial-improvement of any residential structures, including manufactured homes, shall have the lowest floor, including basement, elevated a minimum of one (1) foot above base flood elevation. The elevation of the lowest floor shall be certified by a licensed land surveyor or professional engineer.

(B) Non Residential Construction

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 a minimum of one (1) foot above the base flood elevation or, together with attendant utility and sanitary facilities, be dry floodproofed to a minimum of one (1) foot above the base flood elevation. A registered professional engineer or architect shall certify that the standards of this subsection are satisfied. The elevation of the lowest floor shall be certified by a licensed land surveyor or professional engineer. Such certification shall be provided to the floodplain administrator as set forth in Section 16-503(c)(7)(8)(9).

(C) 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:

(i) A minimum of two (2) openings having a total net area of not less than one (1) square inch for every square foot of enclosed area subject to flooding shall be provided; and

(ii) The bottom of all opening shall be no higher than one (1) foot above grade. Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of flood waters.

(1) All manufactured homes to be placed within all unnumbered and numbered A zones, AE, and AH zones, on the community’s FIRM shall be required to be installed using methods and practices that minimize flood damage. For the purposes of this requirement, manufactured homes must be elevated and anchored to resist flotation, collapse, or lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors. This requirement is in addition to applicable State and local anchoring requirements for resisting wind forces.

(2) Require manufactured homes that are placed or substantially improved within unnumbered or numbered A zones, AE, and AH zones, on the community’s FIRM on sites:

(A) Outside of a manufactured home park or subdivision;

(B) In a new manufactured home park or subdivision;

(D) In an existing manufactured home park or subdivision on which a manufactured home has incurred substantial-damage as the result of a flood, be elevated on a permanent foundation such that the lowest floor of the manufactured home is elevated a minimum of one (1) foot above the base flood elevation and be securely attached to an adequately anchored foundation system to resist flotation, collapse, and lateral movement. The elevation of the lowest floor shall be certified by a licensed land surveyor or professional engineer.

(3) Require that manufactured homes to be placed or substantially improved on sites in an existing manufactured home park or subdivision within all unnumbered and numbered A zones, AE and AH zones, on the community’s FIRM, that are not subject to the provisions of Section 16-504(c)(2), be elevated so that either:

(A) The lowest floor of the manufactured home is a minimum of one (1) foot above the base flood level; or

(B) The manufactured home chassis is supported by reinforced piers or other foundation elements of at least equivalent strength that are no less than thirty-six (36) inches in height above grade and be securely attached to an adequately anchored foundation system to resist flotation, collapse, and lateral movement. The elevation of the lowest floor shall be certified by a licensed land surveyor or professional engineer.

(d) AREAS OF SHALLOW FLOODING (AO and AH zones)

Located within the areas of special flood hazard as described in Section 16-502(a) are areas designated as AO zones. These areas have special flood hazards associated with base flood depths of one (1) to three (3) feet where a clearly defined channel does not exist and where the path of flooding is unpredictable and indeterminate. The following provisions apply:

(1) AO Zones

(A) All new construction and substantial-improvements of residential structures, including manufactured homes, shall have the lowest floor, including basement, elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community’s FIRM (at least two (2) feet if no depth number is specified).

(B) All new construction and substantial-improvements of any commercial, industrial, or other non-residential structures, including manufactured homes, shall have the lowest floor, including basement, elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community FIRM (at least two (2) feet if no depth number is specified) or together with attendant utilities and sanitary facilities be completely floodproofed to that level so that the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy.

(C) Adequate drainage paths shall be required around structures on slopes, in order to guide floodwaters around and away from proposed structures.

(2) AH Zones

(A) The specific standards for all areas of special flood hazard where base flood elevation has been provided shall be required as set forth in Section 16-504(b).

(B) Adequate drainage paths shall be required around structures on slopes, in order to guide floodwaters around and away from proposed structures.

(e) FLOODWAY

Located within areas of special flood hazard established in Section 16-502(a), are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters that carry debris and potential projectiles, the following provisions shall apply:

(1) The community shall select and adopt a regulatory floodway based on the principle that the area chosen for the regulatory floodway must be designed to carry the waters of the base flood without increasing the water surface elevation of that flood more than one (1) foot at any point.

(2) The community shall prohibit any encroachments, including fill, new construction, substantial improvements, and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge.

(3) If Section 16-504(e)(2), is satisfied, all new construction and substantial-improvements shall comply with all applicable flood hazard reduction provisions of Section 16-504.

(4) In unnumbered A zones, the community shall obtain, review, and reasonably utilize any base flood elevation or floodway data currently available from Federal, State, or other sources as set forth in Section 16-504(a)(2).

(f) 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:

(1) Be on the site for fewer than 180 consecutive days, or

(2) Be fully licensed and ready for highway use*; or

(3) Meet the permitting, elevation, and anchoring requirements for manufactured homes of this article.

*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.

(Ord. 323-2016)

16-505. Floodplain management variance procedures.

(a) ESTABLISHMENT OF APPEAL BOARD

The Zoning and Planning Commission, Appeal Board, as established by City of Mount Hope shall hear and decide appeals and requests for variances from the floodplain management requirements of this article.

(b) RESPONSIBILITY OF APPEAL BOARD

Where an application for a floodplain development permit is denied by the Floodplain Administrator, the applicant may apply for such floodplain development permit directly to the Appeal Board, as defined in Section 16-505(a).

The Appeal Board shall hear and decide appeals when it is alleged that there is an error in any requirement, decision, or determination made by the Floodplain Administrator in the enforcement or administration of this article.

Any person aggrieved by the decision of the Appeal Board or any taxpayer may appeal such decision to the District Court as provided in K.S.A. 12-759 and 12-760.

(d) FLOODPLAIN MANAGEMENT VARIANCE CRITERIA

In passing upon such applications for variances, the Appeal Board shall consider all technical data and evaluations, all relevant factors, standards specified in other sections of this article, and the following criteria:

(1) Danger to life and property due to flood damage;

(2) Danger that materials may be swept onto other lands to the injury of others;

(3) Susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;

(4) Importance of the services provided by the proposed facility to the community;

(5) Necessity to the facility of a waterfront location, where applicable;

(6) Availability of alternative locations, not subject to flood damage, for the proposed use;

(7) Compatibility of the proposed use with existing and anticipated development;

(8) Relationship of the proposed use to the comprehensive plan and floodplain management program for that area;

(9) Safety of access to the property in times of flood for ordinary and emergency vehicles;

(10) Expected heights, velocity, duration, rate of rise and sediment transport of the flood waters, if applicable, expected at the site; and,

(11) Costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities such as sewer, gas, electrical, and water systems; streets; and bridges.

(e) CONDITIONS FOR APPROVING FLOODPLAIN MANAGEMENT VARIANCES

(1) Generally, variances may be issued for new construction and substantial-improvements to be erected on a lot of one-half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood elevation, providing items two (2) through six (6) below have been fully considered. As the lot size increases beyond the one-half acre, the technical justification required for issuing the variance increases.

(2) Variances may be issued for the reconstruction, repair, rehabilitation, or restoration of structures listed on the National Register of Historic Places, the State Inventory of Historic Places, or local inventory of historic places upon determination, provide the proposed activity will not preclude the structure’s continued historic designation and the variance is the minimum necessary to preserve the historic character and design of the structure.

(3) Variances shall not be issued within any designated floodway if any increase in flood discharge would result.

(4) Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.

(5) Variances shall only be issued upon: (a) showing of good and sufficient cause, (b) determination that failure to grant the variance would result in exceptional hardship to the applicant, and (c) determination that the granting of a 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 laws or ordinances.

(6) A community shall notify the applicant in writing over the signature of a community official that: (a) the issuance of a variance to construct a structure below base flood level will result in increased premium rates for flood insurance up to amounts as high as $25.00 for $100.00 of insurance coverage and (b) such construction below the base flood level increases risks to life and property. Such notification shall be maintained with the record of all variance actions as required by this article.

(Ord. 323-2016)

16-506. Penalties for violation.

Violation of the provisions of this article or failure to comply with any of its requirements (including violations of conditions and safeguards established in connection with granting of variances) shall constitute a misdemeanor. Any person who violates this article or fails to comply with any of its requirements shall, upon conviction thereof, be fined not more than $25.00, and in addition, shall pay all costs and expenses involved in the case. Each day such violation continues, shall be considered a separate offense. Nothing herein contained shall prevent the (community name) or other appropriate authority from taking such other lawful action as is necessary to prevent or remedy any violation.

(Ord. 323-2016)

16-507. Amendments.

The regulations, restrictions, and boundaries set forth in this article may from time to time be amended, supplemented, changed, or appealed to reflect any and all changes in the National Flood Disaster Protection Act of 1973, provided, however, that no such action may be taken until after a public hearing in relation thereto, at which parties of interest and citizens shall have an opportunity to be heard. Notice of the time and place of such hearing shall be published in a newspaper of general circulation in City of Mount Hope. At least twenty (20) days shall elapse between the date of this publication and the public hearing. A copy of such amendments will be provided to the FEMA Region VII office. The regulations of this article are in compliance with the NFIP regulations.

Risk Premium Rates means those rates established by the Administrator pursuant to individual community studies and investigations, which are undertaken to provide flood insurance in accordance with Section 1307 of the National Flood Disaster Protection Act of 1973 and the accepted actuarial principles. “Risk premium rates” include provisions for operating costs and allowances.

Special Flood Hazard Area see “area of special flood hazard.”

Special Hazard Area means an area having special flood hazards and shown on an FHBM, FIRM or FBFM as zones (unnumbered or numbered) A, AO, AE, or AH.

Start of Construction includes substantial-improvements, and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition placement, or other improvements were within 180 days of the permit date. The actual start means either the first placement of permanent construction of a structure on a site, such as the pouring of slabs or footings, the installation of piles, the construction of columns, any work beyond the stage of excavation, or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling, the installation of streets and/or walkways, excavation for a basement, footings, piers, foundations, the erection of temporary forms, nor installation on the property of accessory structures, such as garages or sheds not occupied as dwelling units or not part of the main structure. For a substantial-improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.

State Coordinating Agency means the Division of Water Resources, Kansas Department of Agriculture, or other office designated by the governor of the state or by state statute at the request of the Administrator to assist in the implementation of the National Flood Insurance Program (NFIP) in that state.

Structure means, for floodplain management purposes, a walled and roofed building, including a gas or liquid storage tank, that is principally above ground, as well as a manufactured home. “Structure” for insurance purposes, means a walled and roofed building, other than a gas or liquid storage tank that is principally above ground and affixed to a permanent site, as well as a manufactured home on a permanent foundation, or a travel trailer, without wheels on a permanent foundation. For the latter purpose, the term includes a building while in the course of construction, alteration or repair, but does not include building materials or supplies intended for use in such construction, alteration or repair, unless such materials or supplies are within an enclosed building on the premises.

Substantial-Damage means damage of any origin sustained by a structure whereby the cost of restoring the structure to pre-damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred.

Substantial-Improvement means any reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure before “start of construction” of the improvement. This term includes structures, which have incurred “substantial-damage,” regardless of the actual repair work performed. The term does not, however, include either (1) any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications that have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions, or (2) any alteration of a “historic structure,” provided that the alteration will not preclude the structure’s continued designation as a “historic structure.”

Variance means a grant of relief by the community from the terms of a floodplain management regulation. Flood insurance requirements remain in place for any varied use or structure and cannot be varied by the community.

Violation means the failure of a structure or other development to be fully compliant with the community’s floodplain management regulations. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance required by this article is presumed to be in violation until such time as that documentation is provided.

Water Surface Elevation means the height, in relation to the National Geodetic Vertical Datum (NGVD) of 1929 (or other datum where specified) of floods of various magnitudes and frequencies in the floodplain riverine areas.
