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.

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,

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.

flooding; and,
(8) Any alteration, repair, reconstruction, or improvements to a
structure which is in compliance with the provisions of this
ordinance, shall meet the requirements of "new construction" as
contained in this ordinance.
(9) Non - Conforming Buildings or Uses. Non - conforming buildings or uses
may not be enlarged, replaced, or rebuilt unless such enlargement
or reconstruction is accomplished in conformance with the
provisions of this ordinance. Provided, however, nothing in this
ordinance shall prevent the repair, reconstruction, or replacement
of a building or structure existing on the effective date of this
ordinance and located totally or partially within the Floodway
Zone, provided that the bulk of the building or structure below
base flood elevation in the Floodway Zone is not increased and
provided that such repair, reconstruction, or replacement meets all
of the other requirements of this ordinance.
SECTION B. SPECIFIC STANDARDS.
In all areas of special flood hazard where base flood elevation data has
been provided, as set forth in Article 3, Section B, or Article 4,
Section C(10), the following provisions are required:
(1) Residential Construction. New construction or substantial
improvement of any residential structure (including manufactured
homes) shall have the lowest floor, including basement, elevated no
lower than 2 feet above the base flood elevation. Should solid
foundation perimeter walls be used to elevate a structure, openings
sufficient to facilitate the unimpeded movements of flood waters
shall be provided.
(2) Non - Residential Construction. New construction or substantial
improvement of any commercial, industrial, or non - residential
structure (including manufactured homes) shall have the lowest
floor, including basement, elevated no lower than 2 feet above the
level of the base flood elevation. Structures located in A -zones
may be floodproofed in lieu of elevation provided that all areas of
the structure below the required elevation are watertight with
walls substantially impermeable to the passage of water, using
structural components having the capability of resisting
hydrostatic and hydrodynamic loads and the effect of buoyancy. A
19
registered professional engineer or architect shall certify that
the standards of this subsection are satisfied. Such certification
shall be provided to the official as set forth in Article 4,
Section B(7).
(3) Manufactured Homes.
(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.

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;

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.
