    Accessory structures shall be firmly anchored in accordance with subsection 10-2.4(C)(1);

    (f)

    Service facilities such as electrical and heating equipment shall be elevated in accordance with subsection 10-2.4(C)(5); and

    (g)

    Flood openings to facilitate automatic equalization of hydrostatic flood forces shall be provided below regulatory flood protection elevation in conformance with the provisions of subsection 10-2.4(D).

    An accessory structure with a footprint less than 150 square feet that satisfies the criteria outlined above does not require an elevation or a floodproofing certificate. Elevation or floodproofing certifications are required for all other accessory structures in accordance with subsection 10-2.4(D)(5)(c).

    (E)

    Floodplains without established base flood elevations. Located within the areas of special flood hazard are streams where no base flood elevation (BFE) data has been provided. The following provisions apply within such areas to any permissible use or any use allowed by variance (in accordance with subsection 7-2.2):

    (1)

    No encroachments, including fill, new construction, substantial improvements or new development shall be permitted within a distance of the stream bank equal to three times the width of the stream at the top of bank or 20 feet each side from top of bank, whichever is greater, unless certification with supporting technical data by a registered professional engineer is provided demonstrating that such encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge.

    (2)

    The BFE used in determining the regulatory flood protection elevation shall be determined based on the following criteria:

    (a)

    When base flood elevation (BFE) data is available from other sources, all new construction and substantial improvements within such areas shall comply with all applicable provisions of this ordinance and shall be elevated or floodproofed in accordance with subsections 10-2.4(C) and (D).

    (b)

    When floodway or nonencroachment area data is available for a federal, state, or other source, all new construction and substantial improvements with floodway and nonencroachment areas shall also comply with the requirements of subsections 10-2.4(D) and (F).

    (c)

    All subdivision, manufactured home park and other development proposals shall provide base flood elevation (BFE) data if development is greater than five acres or has more than 50 lots/manufactured home sites. Such base flood elevation (BFE) data shall be adopted by reference in accordance with subsection 10-2.8 and utilized in implementing this ordinance.

    (d)

    When base flood elevation data is not available from a federal, state, or other source, the reference level shall be elevated or floodproofed (nonresidential) to or above the regulatory flood protection elevation as defined in subsection 10-2.1. All other applicable provision of subsection 10-2.4(D) shall also apply.

    (F)

    Floodways and nonencroachment areas. Located within areas of special flood hazard are areas designated as floodways or nonencroachment areas. The floodways and nonencroachment areas are extremely hazardous areas due to the velocity of floodwaters which carry debris and potential projectiles and have erosion potential. The following provisions shall apply within such areas:

    (1)

    No encroachments, including fill, new construction, substantial improvements and other developments shall be permitted unless:

    (a)

    It has been demonstrated that the proposed encroachment would not result in any increase in the flood levels during the occurrence of the base flood, based on hydrologic and hydraulic analyses performed in accordance with standard engineering practice and presented to the floodplain administrator prior to issuance of a floodplain development permit; or

    (b)

    A conditional letter of map revision (CLOMR) has been approved by FEMA. A letter of map revision (LOMR) must also be obtained upon completion of the proposed encroachment.

    (2)

    If the requirements of subsection (1)(a) are satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this section.

    (3)

    No manufactured homes shall be permitted, except in an existing manufactured home park or subdivision. A replacement manufactured home may be placed on a lot in an existing manufactured home park or subdivision provided the anchoring and the elevation standards of subsection 10-2.4(D)(3) are met and the encroachment standards of subsection (1)(a) above.

    (G)

    Floodplains with base flood elevations but without established floodways or nonencroachment areas. Along rivers and streams where base flood elevation (BFE) data is provided by FEMA or is available from another source but neither floodway nor nonencroachment areas are identified for a special flood hazard area on the FIRM or in the FIS report, the following requirements shall apply to all development within such areas:

    (1)

    Standards of subsections 10-2.4(C) and (D); and

    (2)

    Until a regulatory floodway or nonencroachment area is designated, no encroachments, including fill, new construction, substantial improvements, or other development, shall be permitted unless certification with supporting technical data by a registered professional engineer is provided demonstrating 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.

    10-2.5.

    Special provisions for subdivisions.

    (A)

    An applicant for subdivision plat approval shall be informed by the UDO administrator of the use and construction restrictions contained in subsections 10-2.2, 10-2.3, and 10-2.4 if any portion of the land to be subdivided lies within an area of special flood hazard.

    (B)

    Final plat approval for any subdivision containing land that lies within an area of special flood hazard may not be given unless the plat shows the boundary of the area of special flood hazard and floodway or nonencroachment area boundary and contains, in clearly discernible print, the following statement: "Use of land within an area of special flood hazard is substantially restricted by section 10-2 of the Shelby Unified Development Ordinance".

    (C)

    Subject to the following sentence, a request for final plat approval for any subdivision may not be granted if:

    (1)

    The land to be subdivided lies within a zone where residential uses are permissible and it reasonably appears that the subdivision is designed to create residential building lots;

    (2)

    Any portion of one or more of the proposed lots lies within an area of special flood hazard; and

    (3)

    It reasonably appears that one or more lots described in subsections (C)(1) and (C)(2) could not practicably be used as a residential building site because of the restrictions set forth in subsections 10-2.2, 10-2.3, and 10-2.4.

    The foregoing provision shall not apply if a notice that the proposed lots are not intended for sale as residential building lots is recorded on the final plat, or if the developer otherwise demonstrates to the satisfaction of the authority approving the final plat that the proposed lots are not intended for sale as residential building lots.

    (D)

    All subdivision proposals shall be consistent with the need to minimize flood damage.

    (E)

    All subdivision proposals shall have public utilities and facilities such as water, sewer, gas, and electrical systems located and constructed so as to minimize flood damage.

    (F)

    All subdivisions shall have adequate drainage provided to reduce exposure to flood hazards.

    (G)

    Base flood elevation data shall be provided for subdivision proposals that contain 50 lots or five acres, whichever is less.

    10-2.6.

    Water supply and sanitary sewer systems in areas of special flood hazard. Whenever any portion of a proposed development is located within an area of special flood hazard or whenever replacement water supply and sewage disposal systems are proposed within an area of special flood hazard, the agency or agencies responsible for certifying to the city the adequacy of the water supply and sewage disposal systems for the development (as set forth in subsection 15-7.4) shall be informed by the developer that a specified area within the development lies within an area of special flood hazard. Thereafter, approval of the proposed system by that agency shall constitute a certification that:

    (A)

    Such water supply system is designed to minimize or eliminate infiltration of floodwaters into it.

    (B)

    Such sanitary sewer system is designed to eliminate infiltration of floodwaters into it and discharges from it into floodwaters.

    (C)

    Any on-site sewage disposal system is located to avoid impairment to it or contamination from it during flooding.

    10-2.7.

    Certification requirements.

    (1)

    Elevation certificates:

    (a)

    An elevation certificate (FEMA Form 81-31) is required prior to the actual start of any new construction. It shall be the duty of the permit holder to submit to the UDO administrator a certification of the elevation of the reference level, in relation to mean sea level. The UDO administrator shall review the certificate data submitted. Deficiencies detected by such review shall be corrected by the permit holder prior to the beginning of construction. Failure to submit the certification or failure to make required corrections shall be cause to deny a floodplain development permit.

    (b)

    An elevation certificate (FEMA Form 81-31) is required after the reference level is established. Within seven calendar days of establishment of the reference level elevation, it shall be the duty of the permit holder to submit to the UDO administrator a certification of the elevation of the reference level, in relation to mean sea level. Any work done within the seven day calendar period and prior to submission of the certification shall be at the permit holder's risk. The UDO administrator shall review the certificate data submitted. Deficiencies detected by such review shall be corrected by the permit holder immediately and prior to further work being permitted to proceed. Failure to submit the certification or failure to make required corrections shall be cause to issue a stop-work order for the project.

    (c)

    A final as-built elevation certificate (FEMA Form 81-31) is required after construction is completed and prior to certificate of compliance/occupancy issuance. It shall be the duty of the permit holder to submit to the UDO administrator a certification of final as-built construction of the elevation of the reference level and all attendant utilities. The UDO administrator shall review the certificate data submitted. Deficiencies detected by such review shall be corrected by the permit holder immediately and prior to certificate of compliance/occupancy issuance. In some instances, another certification may be required to certify corrected as-built construction. Failure to submit the certification or failure to make required corrections shall be cause to withhold the issuance of a certificate of compliance/occupancy.

    (2)

    Floodproofing certificate. If nonresidential floodproofing is used to meet the regulatory flood protection elevation requirements, a floodproofing certificate (FEMA Form 81-65), with supporting data, an operational plan, and an inspection and maintenance plan are required prior to the actual start of any new construction. It shall be the duty of the permit holder to submit to the UDO administrator a certification of the floodproofed design elevation of the reference level and all attendant utilities, in relation to mean sea level. Floodproofing certification shall be prepared by or under the direct supervision of a professional engineer or architect and certified by same. The UDO administrator shall review the certificate data, the operational plan, and the inspection and maintenance plan. Deficiencies detected by such review shall be corrected by the applicant prior to permit approval. Failure to submit the certification or failure to make required corrections shall be cause to deny a floodplain development permit. Failure to construct in accordance with the certified design shall be cause to withhold the issuance of a certificate of compliance/occupancy.

    (3)

    If a manufactured home is placed within zone A or AE and the elevation of the chassis is more than 36 inches in height above grade, an engineered foundation certification is required in accordance with the provisions of subsection 10-2.4(D)(3)(b).

    (4)

    If a watercourse is to be altered or relocated, a description of the extent of watercourse alteration or relocation; a professional engineer's certified report on the effects of the proposed project on the flood-carrying capacity of the watercourse and the effects to properties located both upstream and downstream; and a map showing the location of the proposed watercourse alteration or relocation shall all be submitted by the permit applicant prior to issuance of a floodplain development permit.

    (5)

    Certification exemptions. The following structures, if located within zone A or AE, are exempt from the elevation/floodproofing certification requirements specified in subsections (D)(1) and (2) of this section:

    (a)

    Recreational vehicles meeting requirements of subsections (a) and (b) of subsection 10-2.4(D)(4);

    (b)

    Temporary structures meeting requirements of subsection 10-2.4(D)(6); and

    (c)

    Accessory structures less than 150 square feet meeting requirements of subsection 10-2.4(D)(6).

    (E)

    The UDO administrator shall perform, but not be limited to, the following duties:

    (1)

    Review all floodplain development applications and issue permits for all proposed development within special flood hazard areas to assure that the requirements of this ordinance have been satisfied.

    (2)

    Review all proposed development within special flood hazard areas to assure that all necessary local, state and federal permits have been received.

    (3)

    Notify adjacent communities and the North Carolina Department of Crime Control and Public Safety, Division of Emergency Management, State Coordinator for the National Flood Insurance Program prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency (FEMA).

    (4)

    Assure that maintenance is provided within the altered or relocated portion of said watercourse so that the flood-carrying capacity is maintained.

    (5)

    Prevent encroachments into floodways and nonencroachment areas unless the certification and flood hazard reduction provisions of subsection 10-2.4(F) are met.

    (6)

    Obtain actual elevation (in relation to mean sea level) of the reference level (including basement) and all attendant utilities of all new and substantially improved structures, in accordance with the provisions of subsection 10-2.7(D).

    (7)

    Obtain actual elevation (in relation to mean sea level) to which all new and substantially improved structures and utilities have been floodproofed, in accordance with the provisions of subsection 10-2.7(D).

    (8)

    Obtain actual elevation (in relation to mean sea level) of all public utilities in accordance with the provisions of subsection 10-2.7(D).

    (9)

    When floodproofing is utilized for a particular structure, obtain certifications from a registered professional engineer or architect in accordance with the provisions of subsection 10-2.7(D) and subsection 10-2.4(D)(2).

    (10)

    Where interpretation is needed as to the exact location of boundaries of the special flood hazard areas, floodways, or nonencroachment areas (for example, where there appears to be a conflict between a mapped boundary and actual field conditions), make the necessary interpretation. The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in this article.

    (11)

    When base flood elevation (BFE) data has not been provided in accordance with the provisions of section 10.28, obtain, review, and reasonably utilize any BFE data, along with floodway data or nonencroachment area data available from a federal, state, or other source, including data developed pursuant to subsection 10-2.4(E)(2)(b), in order to administer the provisions of this ordinance.

    (12)

    When base flood elevation (BFE) data is provided but no floodway or nonencroachment area data has been provided in accordance with the provisions of subsection 10-2.8, obtain, review, and reasonably utilize any floodway data or nonencroachment area data available from a federal, state, or other source in order to administer the provisions of this ordinance.

    (13)

    When the lowest floor and the lowest adjacent grade of a structure or the lowest ground elevation of a parcel in a special flood hazard area is above the base flood elevation (BFE), advise the property owner of the option to apply for a letter of map amendment (LOMA) from FEMA. Maintain a copy of the LOMA issued by FEMA in the floodplain development permit file. ( OPTIONAL )

    (14)

    Permanently maintain all records that pertain to the administration of this ordinance and make these records available for public inspection, recognizing that such information may be subject to the Privacy Act of 1974, as amended.

    (15)

    Make on-site inspections of work in progress. As the work pursuant to a floodplain development permit progresses, the UDO administrator shall make as many inspections of the work as may be necessary to ensure that the work is being done according to the provisions of the local ordinance and the terms of the permit. In exercising this power, the UDO administrator has a right, upon presentation of proper credentials, to enter on any premises within the jurisdiction of the community at any reasonable hour for the purposes of inspection or other enforcement action.

    (16)

    Issue stop-work orders as required. Whenever a building or part thereof is being constructed, reconstructed, altered, or repaired in violation of this ordinance, the UDO administrator may order the work to be immediately stopped. The stop-work order shall be in writing and directed to the person doing or in charge of the work. The stop-work order shall state the specific work to be stopped, the specific reason(s) for the stoppage, and the condition(s) under which the work may be resumed. Violation of a stop-work order constitutes a misdemeanor.

    (17)

    Revoke floodplain development permits as required. The UDO administrator may revoke and require the return of the floodplain development permit by notifying the permit holder in writing stating the reason(s) for the revocation. Permits shall be revoked for any substantial departure from the approved application, plans, and specifications; for refusal or failure to comply with the requirements of state or local laws; or for false statements or misrepresentations made in securing the permit. Any floodplain development permit mistakenly issued in violation of an applicable state or local law may also be revoked.

    (18)

    Make periodic inspections throughout the special flood hazard areas within the jurisdiction of the community. The UDO administrator and each member of his or her inspections department shall have a right, upon presentation of proper credentials, to enter on any premises within the territorial jurisdiction of the department at any reasonable hour for the purposes of inspection or other enforcement action.

    (19)

    Follow through with corrective procedures of section 5-3.

    (20)

    Review, provide input, and make recommendations for variance requests.

    (21)

    Maintain a current map repository to include, but not limited to; the FIS report, FIRM and other official flood maps and studies adopted in accordance with the provisions of subsection 10-2.8 of this ordinance, including any revisions thereto including letters of map change, issued by FEMA. Notify state and FEMA of mapping needs.

    (22)

    Coordinate revisions to FIS reports and FIRMs, including letters of map revision based on fill (LOMR-Fs) and letters of map revision (LOMRs).

    10-2.8.

    Location of boundaries of areas of special flood hazard. As used in section 10-2, the term "areas of special flood hazard" refers in the first instance to certain areas whose boundaries are determined and can be located on the ground by reference to the specific fluvial characteristics set forth in the definitions of this term. This term also refers to overlay zoning districts whose boundaries are those identified under the cooperating technical state (CTS) agreement between the State of North Carolina and FEMA in its flood insurance study (FIS) and its accompanying flood insurance rate map (FIRM), for Cleveland County dated February 20, 2008, which are adopted by reference and declared to be a part of this ordinance, which boundaries are intended to correspond to the actual, physical location of areas of special flood hazard. (These overlay districts thus differ from other zoning districts whose boundaries are established solely according to planning or policy, rather than physical criteria.) Therefore, the floodplain administrator is authorized to make necessary interpretations as to the exact location of the boundaries of areas of special flood hazards if there appears to be a conflict between a mapped boundary and actual field conditions. Such interpretations, like other decisions of the floodplain administrator, may be appealed to the board of adjustment in accordance with the applicable provisions of this ordinance.

    The initial flood insurance rate maps are as follows for the jurisdictional areas at the initial date:

    Cleveland County Unincorporated Area, dated July 2, 1991.

    City of Shelby, dated April 3, 1978.

    10-2.9.

    Amendments to the official flood hazard zoning and flood insurance rate map; variance procedures.

    (A)

    Amendments to the official flood hazard zoning and flood insurance rate map:

    (1)

    All requests for revisions of areas of special flood hazard boundaries and base flood elevations (BFEs) shall be reviewed and approved by the Federal Emergency Management Agency.

    (2)

    The existing location of any area of special flood hazard as herein above defined may be amended in cases where:

    (a)

    A flood control project of the federal, state, county or city government has substantially altered the flood hazard;

    (b)

    Flood data indicates that the boundaries of either of the areas as shown on the official flood insurance rate map are no longer correct; or

    (c)

    A private individual, corporation, firm or city agency has submitted plans for a channel improvement or relocation requiring an amendment to the official flood insurance rate map.

    (B)

    Variance procedures. Requests for variances from the flood hazard overlay district requirements shall be reviewed by the board of adjustment in accordance with the procedures outlined in subsection 7-2.2.

    10-2.10.

    Regulations do not guarantee flood protection. The degree of flood protection required by this ordinance is considered reasonable for regulating purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by man-made or natural causes.

    10-2.11.

    Setbacks from streams outside designated areas of special flood hazard. In any area that is located outside a designated area of special flood hazard but where a stream is located, no building or fill may be located within a distance of the stream bank equal to five times the width of the stream at the top of the bank or 20 feet on each side, whichever is greater.

    10-2.12.

    Effect on rights and liabilities under the existing flood damage prevention ordinance. This ordinance in part comes forward by re-enactment of some of the provisions of the flood damage prevention ordinance enacted November 19, 2001 as amended, and it is not the intention to repeal but rather to re-enact and continue to enforce without interruption of such existing provisions, so that all rights and liabilities that have accrued there under are reserved and may be enforced. The enactment of this ordinance shall not affect any action, suit or proceeding instituted or pending. All provisions of the flood damage prevention ordinance of the City of Shelby enacted on November 19, 2001 as amended, which are not reenacted herein are repealed.

    10-2.13.

    Effect upon outstanding floodplain development permits. Nothing herein contained shall require any change in the plans, construction, size, or designated use of any development or any part thereof for which a floodplain development permit has been granted by the floodplain administrator or his or her authorized agents before the time of passage of this ordinance; provided, however, that when construction is not begun under such outstanding permit within a period of six months subsequent to the date of issuance of the outstanding permit, construction or use shall be in conformity with the provisions of this ordinance.

(Ord. No. 1-2006, § 1, 1-9-2006; Ord. No. 6-2008, § 1, 2-18-2008)
