HOLDER REGISTER OF DEEDS HARNETT COUNTY, NO NATIONAL FLOOD INSURANCE FLOOD DAMAGE PREVENTION ORDINANCE ADOPTED 9/18/95 NATIONAL FLOOD INSURANCE FLOOD DAMAGE PREVENTION ORDINANCE ARTICLE 1. STATUTORY AUTHORIZATION, FINDINGS OF FACT, PURPOSE AND OBJECTIVES. SECTION A. STATUTORY AUTHORIZATION The Legislature of the State of North Carolina has in Part 6, Article 21 of Chapter 143; Parts 3, and 4 of Article 18 of Chapter 153A; and Article 6 of Chapter 153A of the North Carolina General Statutes, delegated the responsibility to local governmental units to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. Therefore, the Board of Commissioners of Harnett County, North Carolina does ordain as follows: SECTION B.FINDINGS OF FACT (1) The flood hazard areas of Harnett County are subject to periodic inundation which results in loss of life, property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures of flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety, and general welfare. (2) These flood losses are caused by the cumulative effect of obstructions in the floodplain causing increases in flood heights and velocities, and by the occupancy in flood hazard areas by uses vulnerable to floods or hazardous to other lands which are inadequately elevated, floodproofed, or otherwise unprotected from flood damages. SECTION C. STATEMENT OF PURPOSE It is the purpose of this ordinance to promote the public health, safety, and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed to: (1) restrict or prohibit uses which are dangerous to health, safety, and property due to water or erosion hazards, of which result in damaging increases in erosion or in flood heights or velocities; (2) require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; 1 (3) control the alteration of natural floodplains, stream channels, and natural protective barriers which are involved in the accommodation of flood waters; (4) control filling, grading, dredging, and other development which may increase erosion or flood damage; and, (5) prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards to other lands. SECTION D. OBJECTIVES The objectives of this ordinance are: (1) to protect human life and health; (2) to minimize expenditure of public money for costly flood control projects; (3) to minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; (4) to minimize prolonged business interruptions; (5) to minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets, and bridges located in floodplains; (6) to help maintain a stable tax base by providing for the sound use and development of flood prone areas in such a manner as to minimize flood blight areas; and, (7) to insure that potential home buyers are notified that property is in a flood area. ARTICLE 2. Unless specifically defined below, words or phrases used in this ordinance shall be interpreted so as to give them the meaning they have in common usage and to give this ordinance its most reasonable application. 2 "Accessory Structure" means structures which are located on the same parcel of property as the principal structure and the use of which is incidental to the use of the principal structure. Garages, carports and storage sheds are common urban accessory structures. Pole barns, hay sheds and the like qualify as accessory structures on farms, and may or may not be located on the same parcel as the farm dwelling or shop building. "Addition (to an existing building)" means an extension or increase in the floor area or heights of a building or structure. Additions to existing buildings shall comply with the requirements for new construction, unless the addition, renovation or reconstruction to any building, that was constructed prior to the initial Flood Insurance Study for that area, and the addition, renovation or reconstruction does not equal 50% of the present market value of the structure. Where a fire wall is provided between the addition and the existing building, the addition(s) shall be considered a separate building and must comply with the standards for new construction. "Appeal" means a request from a review of the local administrator's interpretation of any provision of this ordinance. "Area of shallow flooding" means a designated AO or VO Zone on a community's Flood Insurance Rate Map (FIRM) with base flood depths from one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and indeterminate, and where velocity flow may be evident. "Area of special flood hazard" is the land in the floodplain within a community subject to a one percent or greater chance of being flooded in any given year.

"Remedy a violation" means to bring the structure or other development into compliance with State or local floodplain management regulations, or if this is not possible, to reduce the impacts of its noncompliance. Ways that impacts may be reduced include protecting the structure or other affected development from flood damages, implementing the enforcement provisions of the ordinance or otherwise deterring future similar violations, or reducing Federal financial exposure with regard to the structure or other development. "Start of construction" (for other than new construction or substantial improvements under the Coastal Barrier Resources Act (P.L. 97 -348), includes substantial improvement, and means the date the building permit was issued, provided the actual start of construction, repair reconstruction, rehabilitation, addition, or improvement was within 180 days of the permit date. The actual start means the first placement of permanent construction of a structure (including a manufactured home) on a site, such as the pouring of slabs or footings, installation of piles, construction of columns, or 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; nor does it include the installation of streets and /or walkways; nor does it include excavation for a basement, footings, piers or foundations, or the erection of temporary forms; nor does it include the installation of the property of accessory buildings, 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 the building, whether or not that alteration affects the external dimensions of the building. III "Structure" means, for floodplain management purposes, a walled and roofed building, a manufactured home, including a gas or liquid storage tank, or other man -made facilities or infrastructures that are principally above ground.

"Substantial improvement" means any repair, 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 the "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 of improvement of a structure to correct existing violations of State or local health, sanitary, or safety code specifications which 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. "Substantially improved existing manufactured home park or subdivision" means where the repair, reconstruction, rehabilitation or improvement of the streets, utilities and pads equals or exceeds 50 percent of the value of the streets, utilities and pads before the repair, reconstruction, or improvement commenced. "Variance" is a grant of relief to a person from the requirements of this ordinance which permits construction in a manner otherwise prohibited by this ordinance where specific enforcement would result in unnecessary hardship. "Violation" mean the failure of a structure or other development to be fully compliant with the community's floodplain management regulations.

(4) In passing upon such applications, the appeal board shall consider all technical evaluations, all relevant factors, all standards specified in other sections of this ordinance, and: (a) the danger that materials may be swept onto other lands to the injury of others; (b) the danger to life and property due to flooding or erosion damage; (c) the susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner; (d) the importance of the services provided by the proposed facility to the community; (e) the necessity to the facility of a waterfront location, where applicable; (f) the availability of alternative locations, not subject to flooding or erosion damage, for the proposed use; (g) the compatibility of the proposed use with existing and anticipated development; (h) the relationship of the proposed use to the comprehensive plan and floodplain management program for that area; 16 (i) the safety access to the property in times of flood for ordinary and emergency vehicles; (j) the expected heights, velocity, duration, rate of rise, and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site; and, (k) the 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, and streets and bridges. (5) The findings listed above shall be submitted to the appeal board, in writing, and included in the application for a variance. (6) Upon consideration of the factors listed above and purposes of this ordinance, the appeal board may attach such conditions to the granting of variances as it deems necessary to further the purposes of this ordinance. (7) Variances shall not be issued within any designation floodway if any increase in flood levels during the base flood discharge would result. (8) Conditions for Variances: (a) Variances may not be issued when the variance will make the structure in violation of other Federal, State, or local laws, regulations, or ordinances. (b) Variances shall only be issued upon determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. (c) Variances shall only be issued upon (i) a showing of good and sufficient cause; (ii) a determination that failure to grant the variance would result in exceptional hardship; and, (iii) a determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisance, cause fraud on or victimization of the public, or conflict with existing local laws or ordinances. 17 (d) Any applicant to whom a variance is granted shall be given written notice specifying the difference between the base flood elevation to which the structure is to be built and a written statement that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation. Such notification shall be maintained with a record of all variance actions. (e) The local administrator shall maintain the records of all appeal actions and report any variances to the Federal Emergency Management Agency upon request. ARTICLE 5.

(a) Manufactured homes that are placed or substantially improved on sites (i)outside a manufactured home park or subdivision; (ii)in a new manufactured home park or subdivision; (iii)in an expansion to an existing manufactured home park or subdivision; or, (iv)in an existing manufactured home park or subdivision on which a manufactured home has incurred "substantial damage" as the result of a flood, must be elevated on a permanent foundation such that the lowest floor of the manufactured home is elevated no lower than 2 feet above the base flood elevation and be securely anchored to an adequately anchored foundation system to resist flotation, collapse, and lateral movement. (b) Manufactured homes that are to be placed or substantially improved on sites in an existing manufactured home park or subdivision that are not subject to the provisions or Article 5, Section B(3a) of this ordinance must be elevated so that the lowest floor of the manufactured home is elevated no lower than 2 feet above the base flood elevation, and be securely anchored to an adequately anchored foundation to resist flotation, collapse, and lateral movement. (c) Manufactured .homes shall be anchored to prevent flotation, collapse, or lateral movement. For the purpose of this requirement, manufactured homes must be anchored to resist flotation, collapse, or lateral movement in accordance with the Regulations for Mobile Homes and Modular Housing adopted by the Commissioner of Insurance pursuant to NCGS 143.15. Additionally, when the elevation would be met by an elevation of the chassis at least 36 inches or less above the grade at the sight, the chassis shall be supported by reinforced piers or other foundation elements of at least equivalent strength. When the elevation of the chassis is above 36 inches in height an engineering certification is required. 20 (d) An evacuation plan must be developed for evacuation of all residents of all new, substantially improved or substantially damaged manufactured home parks or subdivisions located within flood prone areas. This plan shall be filed with and approved by the local administrator and the local Emergency Management coordinator. (4) Recreational Vehicles. A recreational vehicle is ready for highway use if it is on wheels or jacking system, is attached to the site only by quick- disconnect type utilities and security devices, and has no permanently attached additions. Recreation vehicles placed on sites shall either: (a) be on site for fewer than 180 consecutive days and be fully licensed and ready for highway use; or (b) meet the requirements of Article 4, Section B and Article 5, Sections A and B(3). (5) Elevated Buildings. New construction or substantial improvements of elevated buildings that include fully enclosed areas that are usable solely for the parking of vehicles, building access or storage in an area other than a basement and which are subject to flooding shall be designed to preclude finished living space and be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters. (a) Designs for complying with this requirement must either be certified by a professional engineer or architect or meet the following minimum criteria: (i) Provide a minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding; (ii) The bottom of all openings shall be no higher than one foot above grand; and, (iii) openings may be equipped with screens, louvers, valves, or other coverings or devices provided they permit the automatic flow of floodwaters in both directions. 21 (b) Access to the enclosed area shall be the minimum necessary to allow for parking of vehicles (garage door) or limited storage of maintenance equipment used in connection with the premises (standard exterior door) or entry to the living area (stairway or elevator). (c) The interior portion of such enclosed area shall not be partitioned or finished into separate rooms, except to enclose storage areas. (6) Temporary Structures. prior to the issuance of a development permit, for a temporary structure, the following requirements must be met: (a) All applicants must submit to the local administrator prior to the issuance of the development permit a plan for the removal of such structure(s) in the event of a hurricane or flash flood warning notification. The plan must include the following information: (i) a specified time period for which the temporary use will be permitted; the name, address and phone number of the individual responsible for the removal of the temporary structure; (iii) the time frame prior to the event at which a structure will be removed (i.e. minimum of 72 hours before landfall of a hurricane or immediately upon flood warning notification); (iv) a copy of the contract or other suitable instrument with a trucking company to insure the availability of removal equipment when needed; and (v) designation, accompanied by documentation, of a location outside the floodplain to which the temporary structure will be moved. (b) The above information shall be submitted in writing to the local administrator for review and written approval. 22 (7) Accessory Structure. When accessory structures (sheds, detached garages, etc.) with a value of $3,000 or less, are to be placed in (a) Accessory structures shall be used for human habitation (including work, sleeping, living, cooking or restroom areas); (b) Accessory structures shall be designed to have low flood damage potential; (c) Accessory structures shall be constructed and placed on the building site so as to offer the minimum resistance to the flow of floodwaters; (d) Accessory structures shall be firmly anchored in accordance with Article 5, Section A(1); (e) Service facilities such as electrical and heating equipment shall be installed in accordance with Article 5 Section A(4); and (f) Openings to relieve hydrostatic pressure during a flood shall be provided below base flood elevation in conformance with Article 5 Section B(5). (8) Floodways. Located within areas of special flood hazard established in Article 3, Section B, are areas designated as floodways. The floodway is an extremely hazardous area due to the velocity of flood waters which carry debris and potential projectiles and has erosion potential. The following provisions shall apply within such areas: (a) No encroachments, including fill, new construction, substantial improvements and other developments shall be permitted 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 the flood levels during the occurrence of the base flood. Such certification and technical data shall be presented to the local administrator. (b) If Article 5, Section B(8) (a) is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of Article 5. 23 (c) 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 Article 5, Section B(3) are met. SECTION C. STANDARDS FOR STREAMS WITHOUT ESTABLISHED BASE FLOOD ELEVATIONS AND /OR FLOODWAYS. Located within the areas of special flood hazard established in Article 3, Section B, are small streams where no base flood data has been provided or where no floodways have been identified. The following provisions apply within such areas: (1) No encroachments, including fill, new construction, substantial improvements or new development shall be permitted within a distance of the stream bank equal to the setback established by the Coastal Area Management Act (CAMA) regulations. Where no setback is established by LAMA regulations, the area of no encroachment shall be twenty fee each side from top of bank, 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) If Article 5, Section C(1) is satisfied and base flood elevation data is available from other sources, all new construction and substantial improvements within such areas shall comply with all applicable flood hazard ordinance provisions of Article 5 and shall be elevated or floodproofed in accordance with elevations established in accordance with Article 4, Section C(10) . When base flood elevation data is not available from a Federal, State, or other source, the lowest floor, including basement, shall be elevated at least two (2) feet above the highest adjacent grade. SECTION D. STANDARDS FOR SUBDIVISION PROPOSALS. (1) All subdivision proposals shall be consistent with the need to minimize flood damage; (2) All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical, and water systems located and constructed to minimize flood damage; 24 (3) All subdivision proposals shall have adequate drainage provided to reduce exposure to flood hazards; and, (4) Base flood elevation data shall be provided for subdivision proposals and other proposed development which is greater than the lesser of fifty lots or five acres. SECTION E. STANDARDS FOR AREAS OF SHALLOW FLOODING (AO ZONES). Located within the areas of special flood hazard established in Article 3, Section B, are areas designated as shallow flooding. 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 shall apply within such areas: (1) All new construction and substantial improvements of residential structures shall have the lowest floor, including basement, elevated to the depth number specified on the Flood Insurance Rate Map, in feet, above the highest adjacent grade. If no depth number is specified, the lowest floor, including basement, shall be elevated at least two (2) feet above the highest adjacent grade. (2) All new construction and substantial improvements of non- residential structures shall: (a) have the lowest floor, including basement, elevated to the depth number specified on the Flood Insurance Rate Map, in feet, above the highest adjacent grade. If no depth number is specified, the lowest floor, including basement, shall be elevated at least two (2) feet above the highest adjacent grade; or, (b) be completely floodproofed together with attendant utility and sanitary facilities to or above that level so that any space below that level 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. 25 ARTICLE 6.
