[Ord. No. 99-99 §1, §1, 7-12-1999; Ord. No. 10-041 §18, 6-2-2010]
A. 
It is the purpose of this Article to promote the public health, safety and general welfare; to minimize losses from periodic flooding; 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) by applying the provisions of this Article to:
1. 
Restrict or prohibit uses which are dangerous to health, safety, or property in times of flooding or cause undue increases in flood heights or velocities.
2. 
Require that uses vulnerable to floods, including public facilities which serve such uses, be provided with flood protection at the time of the initial construction.
3. 
Protect individuals from buying lands which are unsuited for intended purposes because of flood hazard.
[Ord. No. 99-99 §1, 7-12-1999; Ord. No. 10-041 §19, 6-2-2010]
The special flood hazard areas of St. Charles County, Missouri, are subject to inundation, which results in the 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 public health, safety, and general welfare.
[Ord. No. 99-99 §1, 7-12-1999]
A. 
Flood losses are caused by:
1. 
The cumulative effect of obstructions in floodways causing increases in flood heights and velocities; and
2. 
The occupancy of flood hazard areas by uses vulnerable to floods or hazardous to others, which are inadequately elevated or otherwise unprotected from flood damages.
[Ord. No. 99-99 §1, 7-12-1999; Ord. No. 01-054 §1, 4-25-2001; Ord. No. 03-142 §1(38), 10-1-2003; Ord. No. 10-041 §20, 6-2-2010]
A. 
This Article of the Unified Development Ordinance uses a reasonable method of analyzing flood hazards, which consist of a series of interrelated steps.
1. 
Selection of regulatory flood which is based upon engineering calculations that permit a consideration of such flood factors as its expected frequency of occurrence, the area inundated, and the depth of inundation. The regulatory flood selected for this Article of the Unified Development Ordinance is representative of large floods which are reasonably characteristic of what can be expected to occur on the streams subject to these regulations. It is in the general order of a flood which can be expected to have a one percent (1%) chance of occurrence in any one (1) year, as delineated on the Federal Emergency Management Agency's Flood Insurance Study, Flood Insurance Rate Maps, and illustrative materials dated March 9, 2021, as amended hereafter.
[Ord. No. 21-008, 1-25-2021]
2. 
Calculation of water surface profile based on a hydraulic engineering analysis of the capacity of the stream channel and overbank areas to convey the regulatory flood.
3. 
Computation of the floodway required to convey this flood without increasing flood heights more than one (1) foot at any point.
4. 
Delineation of floodway encroachment lines within which no obstruction is permitted which would cause any increase in flood height.
5. 
Delineation of floodway fringe (i.e., that are outside the floodway encroachment lines), but which still is subject to inundation by the regulatory flood.
6. 
Delineation of density floodway (i.e., the area outside the floodway encroachment lines which is not included in the Floodway Fringe Overlay District, but which still is subject to inundation by the regulatory flood).
[Ord. No. 99-99 §1, 7-12-1999; Ord. No. 10-041 §21, 6-2-2010]
A. 
It is the purpose of this Unified Development Ordinance Article to promote public health, safety, and general welfare, and to minimize those losses described in Part 1, Sections 405.025 through 405.030, Chapter 405 and Part 1, Sections 405.010, 405.015 and 405.077, Chapter 405 by applying the provisions of this Unified Development Ordinance Article to:
1. 
Restrict or prohibit uses which are dangerous to public health, safety, or property in times of flooding, or cause undue increases in flood heights or velocities.
2. 
Require that uses vulnerable to floods, including public facilities which serve such uses, be provided with flood protection at the time of initial construction.
3. 
Protect individuals from buying lands which are unsuited for intended purposes because of flood hazard.
4. 
Ensure that eligibility is maintained for property owners in the County to purchase flood insurance in the National Flood Insurance Program.

B. 
The duties of the Director of the Division of Planning and Zoning under this Article of the Unified Development Ordinance shall include, but not be limited to:
1. 
Review all permit applications to determine whether proposed building sites will be reasonably safe from flooding. If the proposed building site is in a flood-prone area, all new construction and substantial improvements shall:
a. 
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;
b. 
Be constructed of materials resistant to flood damage;
c. 
Be constructed by methods and practices that minimize flood damage; and
d. 
Be constructed with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities permanently elevated to a minimum of one (1) foot above base flood elevation.
2. 
Review proposed development to assure that all necessary permits have been received from those governmental agencies from which prior approval is required by Federal or State law, including Section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. 1334.
3. 
Notify, in riverine situations, adjacent communities and the State Emergency Management Agency and require the submittal of a map revision to the Federal Emergency Management Agency (FEMA) prior to any alteration or relocation of a watercourse, and submit copies of evidence of such notifications to FEMA.
4. 
Ensure that the flood-carrying capacity within the altered or relocated portion of any watercourse is maintained by method of hydrologic analysis.
5. 
Obtain and maintain a record of the elevation (in relation to mean sea level) of the lowest floor, including crawl spaces and enclosed areas below the first finished floor, and lowest floor of all new and substantially improved structures.
6. 
Obtain, if a non-residential structure has been dry-floodproofed in accordance with attendant utility and sanitary facilities, and maintain a design such that below one (1) foot above the base flood level the structure is watertight, with the 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, the elevation (in relation to mean sea level) to which the structure was floodproofed.
7. 
When dry-floodproofing is utilized for a non-residential structure, the Director of the Division of Planning and Zoning shall be presented certification from a registered professional engineer that the design and methods of construction are in accordance with accepted standards of practice for meeting the applicable Sections of this Chapter or Chapter 410. A record of such certificates, which includes the specific elevation (in relation to mean sea level) to which such structures are floodproofed, shall be maintained by the Director of the Division of Planning and Zoning.
8. 
Review and approve requests for administrative variance for accessory and agricultural structures. All requests for administrative variances must meet the standards set forth within Section 405.375 (E) and (F) of this Article, and may be subject to review by the Board of Zoning Adjustment as defined within Section 405.375.

No person, firm or corporation shall initiate any development not exempt under Section 412.050(A)(8), substantial improvement, or regrading of a property used for non-agricultural purposes, or cause the same to be done in a designated flood hazard area, without first obtaining a separate floodplain development permit for each improvement on the property.
[Ord. No. 99-99 §1, 7-12-1999; Ord. No. 01-054 §1, 4-25-2001; Ord. No. 01-111 §1, 9-26-2001; Ord. No. 05-029 §1, 3-29-2005; Ord. No. 07-040 §1, 3-13-2007; Ord. No. 10-041 §26, 6-2-2010]
A. 
To obtain a floodplain development permit, the applicant must apply for such a floodplain development permit with the County Division of Planning and Zoning. A floodplain development permit must be signed by the applicant on the form furnished. For the purpose of investigating an application for a floodplain development permit and monitoring compliance with it, an applicant authorizes the Community Development Department's staff, or staff of other agencies at the Department's direction, to enter and inspect the subject property while work authorized by that permit is in progress. This authority shall cease upon completion of that work and closure of the permit. Every such floodplain development permit shall:
1. 
Describe the land on which the proposed work is to be done by lot, block and tract, house and street address, or similar description that will readily identify and specifically locate the proposed structure or work.
2. 
Identify and describe the work to be covered by the floodplain development permit.
3. 
Indicate the use or occupancy for which the proposed work is intended.
4. 
Indicate the current market value of the structure. For the purposes of this Section, the current market value of the structure shall be determined by the St. Charles County Assessor, adjusted to approximate market value, or a State-licensed appraiser, at the option of the landowner.
[Ord. No. 18-014 § 1, 1-29-2018]
5. 
Specify whether development is located in designated flood fringe or floodway.
6. 
Identify the existing base flood elevation and the elevation of the proposed development, including without limitation, the crawl space or basement, heating, cooling or other mechanical components, and garage, of all structures or areas to be filled on the property.
7. 
Give such other information as reasonably may be required by the Director of the Division of Planning and Zoning.
8. 
Be accompanied by plans and specifications for proposed construction, fill area, or grading.
9. 
Be signed by the property owner or his/her authorized agent who may be required to submit evidence to indicate such authority.
10. 
Be issued by the Director of the Division of Planning and Zoning or his or her designee.
11. 
Be accompanied by a fee as set by ordinance. The fee is not applicable for any reissue of a Floodplain Development Permit for a structure within a consecutive twelve (12) month period. If a Letter of Map Revision (LOMR) is required, the applicant shall submit publication fees for community notification.
12. 
Be valid for the same period as the Building Permit. In the event there is no Building Permit, the Floodplain Development Permit will be in effect for two (2) years from the date of issuance.

Editor's Note—For designation of the division of planning and zoning, see ord. no. 02-204 adopted 12-23-2002 set out in ch. 132 of this code and ord. no. 03-195 adopted 12-31-2003.
[Ord. No. 99-99 §1, 7-12-1999; Ord. No. 01-054 §1, 4-25-2001; Ord. No. 07-040 §1, 3-13-2007; Ord. No. 10-041 §28, 6-2-2010]
A. 
A structure may be improved (remodeled, repaired or enlarged) without conforming to current requirements for elevation, as long as the cumulative value of all work done within a consecutive five-year period does not exceed fifty percent (50%) of the current market value of the structure. Permits for incremental improvements, additions and repairs shall be tracked by the Division of Planning and Zoning beginning January 1, 2005.
[Ord. No. 18-014 § 2, 1-29-2018]
B. 
If the cumulative value of the improvements exceeds fifty percent (50%) of the current market value of the structure, the structure must be brought into compliance with Subsection (C) of Section 405.350 of this Article, Standards for the Floodway Overlay District, the Floodway Fringe Overlay District, and the Density Floodway Overlay District, which requires elevation of residential structures to one (1) foot above the base flood elevation or the elevation/dry-floodproofing of non-residential structures to or above the base flood elevation.
[Ord. No. 18-014 § 1, 1-29-2018]
C. 
In any case, however, the structure's owner may apply to the Director of Planning and Zoning for a determination that the structure is a "repetitive loss structure" as defined at Section III-D-3-a-(1) of the National Flood Insurance program's authorized forms for flood insurance, 44 C.F.R. Part 61, Appendices A(1), (2) and (3). The structure's owner shall make that application on a form provided by the Director and the Director shall make that determination in writing, based on information supplied by the structure's owner as well as information and records relating to the structure retained by the Division of Planning and Zoning, and shall serve that determination upon the structure's owner.

[Ord. No. 99-99 §1, 7-12-1999; Ord. No. 07-040 §1, 3-13-2007]
A. 
The mapped floodplain areas within the jurisdiction of this Article of the Unified Development Ordinance are hereby divided into the three (3) following districts:
1. 
A Floodway Overlay District (FW),
2. 
A Floodway Fringe Overlay District (FF), and
3. 
A Density Floodway Overlay District (DF) identified in the Flood Insurance Study (Flood Insurance Rate Maps (FIRM)).
B. 
Within these districts, all uses not meeting the standards of this Article of the Unified Development Ordinance and those standards of the underlying zoning district are prohibited. These zones shall be consistent with the A Zones (including AE Zone), as identified on the official FIRM and identified in the Flood Insurance Study provided by the Federal Emergency Management Agency.
[Ord. No. 99-99 §1, 7-12-1999; Ord. No. 07-040 §1, 3-13-2007; Ord. No. 10-041 §29, 6-2-2010]
A. 
No floodplain development permit shall be granted for new construction, substantial improvement, and other improvements including the placement of manufactured homes, modular homes, and mobile homes within all A Zones (including AE Zone), unless the conditions of this Article are satisfied.
B. 
No new construction, substantial improvements or other development, including structural and non-structural development, shall be permitted within A Zones on the FIRM unless the base flood elevation and floodway delineation data are provided by the applicant. The County shall utilize any base flood or floodway delineation data currently available from Federal, State or other sources. If data is not available, the Director of Planning and Zoning shall require the applicant to provide technical modeling analysis establishing the BFE and floodway delineation.
C. 
New construction, subdivision plats, substantial improvements, prefabricated buildings, placement of manufactured homes, mobile homes, or modular homes, and other developments, shall require:
1. 
Design for adequate anchorage to prevent flotation, collapse, or lateral movement due to flooding of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy.
2. 
New and replacement water supply systems and/or sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into floodwaters, and on-site waste disposal systems be located so as to avoid impairment or contamination from them during flooding.
3. 
Construction with materials resistant to flood damage, utilizing methods and practices that minimize flood damage, and with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities that are dry-floodproofed or permanently located so as to prevent water from entering, damaging, or accumulating within the components during conditions of flooding.
4. 
All new and replacement utility and sanitary facilities be elevated or dry-floodproofed up to the regulatory flood protection elevation of one (1) foot above base flood elevation. Single electric service for recreational uses must be elevated a minimum of ten (10) feet above existing average grade.
5. 
That, until a floodway has been designated, no new construction, substantial improvements, or other development (including fill) shall be permitted within Zones A and AE on the County's 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 elevation more than one (1) foot at any point within the County.
6. 
Storage of material and equipment.
a. 
The storage or processing of materials that are, in time of flooding, buoyant, flammable, explosive or could be injurious to human, animal or plant life is prohibited unless the storage of such materials is in an approved floodproofed and/or tethered containment.
b. 
Storage of other material or equipment may be allowed if not subject to major damage by floods and firmly anchored to prevent flotation, or if readily removable from the area within the time available after flood warning.
c. 
All company owned L.P. gas tanks, one hundred twenty-five (125) gallons and larger, that are threatened by high water conditions are to be tethered with a suitable material (please see suggested L.P. Gas Tank Tie Down method), or elevated on reinforced concrete piers in a manner that will prevent uncontrolled movement and/or flotation of the tank.
Note: In that all tanks may not be affected by floodwater on an annual basis, a permanent tether may not be required. The tether, itself, could be a threat to personal safety and property damage, although it shall remain the responsibility of the tank's owner to adequately tether the tank before flotation occurs. In areas where there is a flash flood potential, permanent tethers must be utilized.
d. 
All company owned L.P. gas tanks are to be identified with the name and a telephone number of the distributor or local office responsible for servicing the tank. This information shall be placed on a clearly visible surface of the tank.
e. 
All L.P. gas jobbers doing business in St. Charles County must register with the proper authority, Emergency Management Agency, providing the name of the company, the location of the local branch or office, an emergency telephone number, and the name of a contact person(s). Such reports shall be kept current at all times. The Division of Emergency Management shall provide such information to appropriate fire protection districts.
7. 
Review subdivision proposals and other proposed new developments, including manufactured home parks or subdivisions, to determine whether such proposals will be reasonably safe from flooding. If a subdivision proposal or other proposed new development is in a flood-prone area, any such proposals shall be reviewed to ensure that:
a. 
All such proposals are consistent with the need to minimize flood damage within the flood-prone area.
b. 
All public utilities and facilities, such as sewer, gas, electrical, and water systems, are located and constructed to eliminate flood damage.
c. 
Adequate drainage is provided to reduce exposure to flood hazards.
d. 
Subdivision proposals for developments (including proposals for manufactured home parks and subdivisions) greater than fifty (50) lots or five (5) acres, whichever is the lesser, shall be included within such base flood elevation data.
e. 
Subdivision plats on filled areas in floodplain overlay districts must apply for a letter of map revision from FEMA prior to construction of any residences.
8. 
Structures (agricultural) used solely for agricultural purposes in connection with the production, harvesting, storage, drying, or raising of agricultural commodities, including the raising of livestock, 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; there is no permanent retail, wholesale, or manufacturing use included in the structure; a variance has been granted from the floodplain management requirements of this Chapter; and a floodplain development permit has been issued.
9. 
Structures (accessory) 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 four hundred (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; a variance has been granted from the standard floodplain management requirements of this Chapter; and a floodplain development permit has been issued.

A. 
Permitted Uses. Only uses having a low flood-damage potential and not obstructing flood flows shall be permitted within the Floodway District to the extent that they are not prohibited by any other Section of the Unified Development Ordinance. All encroachments, including fill, new construction, substantial improvements and other developments are prohibited unless certification by a registered professional engineer is provided, demonstrating that encroachments shall not result in any increase in flood levels during occurrence of the base flood discharge. No use shall increase flood levels of the regulatory flood elevation. These uses are subject to the standards of the Floodway, Floodway Fringe, and Density Floodway Overlay Districts. The following are recommended uses for the Floodway District:
1. 
Agricultural uses, such as general farming, pasture, nurseries, and forestry.
2. 
Residential accessory uses, such as lawns, gardens, and parking and play areas.
3. 
Non-residential areas, such as loading areas, parking, and airport landing strips.
4. 
Public and private recreational uses, such as golf courses, archery ranges, picnic grounds, parks, wildlife, and nature preserves.
5. 
In Zone A, obtain, review, and reasonably utilize any floodway data available through Federal, State, or other sources or Section 405.350, Standards for the Floodway Overlay District, the Floodway Fringe Overlay District and the Density Floodway Overlay District, Subsection (C)(7) of this Article in meeting the standards of this Article.
[Ord. No. 99-99 §1, 7-12-1999; Ord. No. 01-054 §1, 4-25-2001; Ord. No. 03-142 §1(45), 10-1-2003; Ord. No. 07-040 §1, 3-13-2007; Ord. No. 10-041 §33, 6-2-2010]
A. 
Purpose. The purpose of the density floodway is to address a variety of issues related to the planning, development, and management of the floodplain and to do so by permitting development to occur in a fashion that disperses and spreads it throughout the density floodway. The following criteria must be considered in minimizing the negative impacts of encroachments on flood flows across the density floodway: the density floodway regulations apply to the development that occurs coincidentally behind a uniform 20-year levee at the L15 location; the configuration or orientation of development within each lot/parcel will be such as to minimize the loss of effective conveyance for the entire density floodway; the development of each lot/parcel shall be located on one (1) of the higher areas of the lot/parcel and oriented in such a way that its location and orientation provide the greatest overall floodplain conveyance.
B. 
Permitted Uses. Any use permitted in Section 405.365, Floodway Overlay District of this Article shall be permitted in the Density Floodway Overlay District to the extent that they are not prohibited by any other Unified Development Ordinance Section. These uses are subject to Section 405.350, Standards for the Floodway Overlay District, the Floodway Fringe Overlay District and the Density Floodway Overlay District, of this Article.
C. 
Standards For The Density Floodway Overlay District.
1. 
With a "No-Rise Certification", any development on a lot/parcel which creates fill or blockage in the density floodway shall be permitted. A no-rise certification shall be provided by a registered professional engineer demonstrating that the development shall not result in any increase in the base flood elevation. The analysis for the no-rise certification must be calculated and evaluated on a lot/parcel basis only; it is not to be calculated for the entire density floodway. Such development can be caused by activities including fill (which shall include continuous fill, with the exception of a uniform 20-year levee at the L15 location), new construction, substantial improvements, and minor improvements.
2. 
Lacking a "No-Rise Certification", the maximum surface area of each lot/parcel that can be developed is limited to not more than eighteen percent (18%). Any such fill or development must not be continuous (with the exception of a uniform 20-year levee at the L15 location) or contiguous with other developments so as to restrict the flow of floodwater, in keeping with the purpose statement (Section 405.015) of this Chapter. In the event that continuous or contiguous fill or development is deemed necessary, the provisions of Subsection (C)(1) of this Section must be met. Percent development is equal to the surface area of a lot/parcel within the density floodway as recorded in the St. Charles County Recorder of Deeds office on or before December 15, 1992, that will be occupied by a development divided by the total surface area of the lot/parcel expressed as a percentage. Structures which are constructed to replace structures existing before December 15, 1992, but which are demolished after December 15, 1992, will not be counted toward the eighteen percent (18%) limitation on development.
3. 
Once the eighteen percent (18%) limitation on development on a lot/parcel has been attained, no future development shall be allowed, unless allowed pursuant to a "No-Rise Certification", as stated in Section 405.370, Density Floodway Overlay District, Subsection (C)(1) of this Article.
4. 
The future sale of a portion of a lot/parcel in the density floodway shall result in the remaining developed area being apportioned between the lots/parcels, unless it is set out differently in the deeds as recorded in the St. Charles County Recorder of Deeds office on or before December 15, 1992.
5. 
St. Charles County intends to maintain the eighteen percent (18%) of developable area for each lot/parcel and the total area of the density floodway, as depicted on the Flood Insurance Rate Map (FIRM), dated March 17, 2003, as amended hereafter.
D. 
Application Procedure For Floodplain Development Permits In The Density Floodway.
1. 
When an individual requests a floodplain development permit in the density floodway, the following materials will be provided to the applicant upon the submittal of the deed to the property recorded on or before December 15, 1992:

a. 
Review submittal to determine compliance.
b. 
Release a floodplain development permit (in most applications to allow construction of foundation only).
c. 
Upon submittal of a second (2nd) elevation (certificate), release approved floodplain development permit, if elevation meets or exceeds requirement of one (1) foot above the 100-year floodplain.
d. 
Record the actual loss of area for the lot/parcel on the Assessor's tax parcel map(s).
