PURPOSE: To receive public comment on proposed amendments to the Flood Damage
Prevention Ordinance and seek guidance for such revisions.
BACKGROUND: Orange County has developed a series of regulations to prevent building
activity in its flood-prone areas, as well as to preserve the environmental attributes. Even
though Orange County has been a leader in floodplain management through its work in
planning, erosion and sedimentation control, Lands Legacy, and building inspection divisions,
the county has not availed itself of federal programs that would financially recognize our efforts
through insurance rate rebates and other grant opportunities.
Orange County first became a participating community in the National Flood Insurance Program
(NFIP) in 1975 and entered the regular FEMA-NFIP on March 16,1981 with the adoption of a
flood damage prevention ordinance, This is the same effective date for the Flood Insurance
Rate Maps (FIRMs). The BOCC last revised the present ordinance in 1995. The County
adopted its original soil erosion and sedimentation control standards in 1975 and its Neuse
River Basin stormwater regulations in 2001 and stream buffer use restrictions in 1994, In short,
Orange County has a long, documented history of comprehensive land development
regulations focused on our water resources and stream corridors,
On ,June 18, 2004, North Carolina Floodplain Mapping Program staff scheduled a preliminary
map meeting at which time they presented new preliminary FIRM panels and Flood Insurance
Study (FIS) Report to the County for the Neuse Basin streams. The new FIRMS panels altered
the existing floodplains, expanding them in some areas and decreasing them in others. The
new elevation reference (NAND 1983) is about 0,7 feet different from the original reference
(NGVD 1929), plus hydrologists used better topographic data.

FEMA has designated the State of North Carolina as a Cooperating Technical State (CTS)..
The State has assumed primary responsibility for the FEMA NFIP mapping for all North
Garolina communities, including Orange County. North Garolina Floodplain Mapping Program
has prepared new FIRM panels for the Cape Fear and Roanoke Basin streams in Orange
County. They are now available from the Planning Department.
The county's interest in the proper management of floodplain areas has fostered an interest in
the Federal Emergency Management Administrations (FEMA) Community Rating System
(CRS) through the National Flood Insurance Program (NFIP), which provides federally flood
insurance backing to private property owners. CRS is a voluntary program for local government
to encourage, enact, and enforce floodplain regulations and documents past and present
county regulatory history, which could take our efforts to a higher level or compliance and
awareness. The CRS recognizes and encourages community floodplain management activities
that exceed the minimum NFIP requirements. As a result, flood insurance premium rates can be
discounted to reflect the reduced flood risk resulting from the community actions meeting the
three goals of the CRS: (1) reduce flood losses; (2) facilitate accurate insurance rating; and (3)
promote the awareness of flood insurance.
Benefits that communities can expect from participation in the CRS program may include the
following:
1. Reduced privately held flood insurance premiums,
2. Enhanced public safety,
3. Reduction in damage to property and public infrastructure,
4. Avoidance of economic disruption and human suffering,
5. More comprehensive environmental protection,
6. Orange County can evaluate the effectiveness of its flood program against national
benchmarks,
7. Added incentive to maintain other watershed protections,
8. Enhanced quality of life, and
9. Qualification for certain federal assistance programs.
In a coordinated effort with the new FIRM preparation, FEMA and the North Carolina
Emergency Management (NCEM) -Mitigation Division are encouraging Orange County to
participate in the GRS program. On December 14, 2004, letters, under the County Manager's
signature, were sent to the Region IV FEMA Community Mitigation Program and to the North
Carolina Division of Emergency Management, Floodplain Management Branch to, "Initiate the
formal process to participate in the NFIP's CRS." In response to our initiative, FEMA responded
with a letter to confirm a Community Assistance Visit (CAV) during the week of February 21, As
a follow up to the letter, FEMA Region V and NCEM staff scheduled a CAV on February 22 and
23. Our last CAV was on June 21, 1995.
A summary of the CAV recommendations include the following three items:
1. Orange County should adopt the revised flood damage prevention ordinance, (The State
of North Carolina has drafted a model ordinance, which would re-enact and continue the
existing law, Staff has adapted the NC model to the existing ordinance text.)
2. Within the basic flood zone, county zoning and building inspectors should require base
flood elevation (BFE) and lowest floor elevation (LFE) data for each new structure and
repair and expansion of existing buildings, and require a surveyed plot plan to establish
building improvement locations and elevations, if floodplains are involved.
i-h:n.. i d4. `,: !'ul i. ~ v ~x. V.i: Li ::; dfJr ~ 7 ~u:Liu iil
3. Develop specific administrative procedures to deal directly with substantial damage to
flood-prone structures and to complement the existing procedures described in the flood
damage prevention ordinance,
Through this CRS process, staff has initiated several small projects to improve the county's
ability to administer its regulations and educate the public regarding floodplain regulations,
These actions include the following:
1. Within the Orange County website, under Current Planning, flood elevation certificates
are available, as well as, instructions to complete the document and the county flood
damage prevention ordinance.
2, Staff now logs in all relevant floodplain information inquiries.
3. Forms to respond to formal floodplain data requests.
4, A floodplain insurance data form for hand out to any interested citizen,
5. The 2004 Neuse Basin floodplain maps for Orange County are now a layer in the
Planning Department GIS.
6, The 2004 Neuse Basin and Cape Fear Basin floodplain maps for Orange County are
now available for viewing in the Planning Department's map room.
7. All parcels with structures located within flood prone areas now have a notice on them
within the Building Inspection permit system, so that no improvements or additions are
allowed unless flood and first floor elevation data are provided.
8, Both the Planning Department and County libraries have books, pamphlets, and
brochures on the NFIP and flood proofing buildings,
To continue with the GRS process, the FEMA representative requested that the county forward
a draft copy of the proposed revisions to the present flood damage prevention ordinance,
administrative procedures to process building permits, which involve stnactures in or very near
floodplain areas, and a listing of residences built in floodplain areas since 1981.
FINANCIAL IMPACT: Additional departmental staff time will be required to properly
administrate the revised flood damage prevention ordinance.
The use of the revised regulations, a condition of participation in the Community Rating System,
could provide public financial benefits in the farm of flood insurance rebates. Department
involvement would eventually include, but not be limited to Planning and Inspections
Department, EMS, Information Services, Public Works, Environmental and Resource
Conservation, and Parks and Recreation.
RECOMMENDATION(S): The Administration recommends that the Board close the
public hearing and adopt the amended ordinance,

DIVISION 1. GENERALLY
Sec. 42-.31 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 15.3A; and Part 121, 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 Orange County, North Cazolina, does ordain as follows:
(Ord. of 8-28-1995, § 1.1, eff. 8-28-1995)
Sec. 42-32 Findings of fact.
a) The flood 1}a~ard prone areas within the jurisdiction of the Orange 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.
b) These flood losses are caused by the cumulative effect of obstructions in floodplains causing
increases in flood heights and velocities, and by the occupancy in flood hazz~trd prone areas
by uses vulnerable to floods or hazazdees to other lands, which are inadequately elevated,
flood proofed, or otherwise unprotected from flood damages.
(Ord. of 8-28-1995, § I.1, eff. 8-28-1995)
Sec. 42-.3.3 Statement of purpose.
It is the purpose of this uric-le Ordinance to promote public health, safety, and general
welfare uid to minimize public and private losses due to flood conditions irrspeEr€re within flood prone
areas by provisions designed to:
a. Restrict or prohibit uses, which are dangerous to health, safety, and property due to water or
erosion hazards, or which result in damaging increases in erosion, flood heights or velocities;

b. Require that uses vulnerable to floods, including facilities, which serve such uses, be
protected against flood dunage at the time of initial construction;
a Control the alteration of natural floodplains, stream channels, and natural protective barriers,
which are involved in the accommodation of flood waters;
d. Control filling, grading, dredging, and all other development, which may increase erosion or
flood damage; and
e. Prevent or regulate the construction of flood barriers, which will unnaturally divert
floodwaters or which may increase flood hazards to other lands.
(Ord. of 8-28-1995, § 1.1, eff: 8-28-1995)
Sec. 42-34 Objectives.
The objectives of this Ordinance are to:
a, Protect human life and health;
b. Minimize expenditure of public money for costly flood control projects;
c, Minimize the need for rescue and relief efforts associated with flooding and generally
undertaken at the expense of the general public;
d. Minimize prolonged business losses and interruptions;
e. Minimize damage to public facilities and utilities such as water and gas mains, electric,
telephone, cable and other communication facilities, and sewer lines, streets, and bridges
located in floodplains gone areas;
£ 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
g. Ensure that potential homebuyers are notified that property is in a Heed Special Flood
Hazard Area.

exceed 50 percent of the mazlcet value of the structure before the damage occurred. See defmition of
"substantial improvement." Substantial damage also means flood-related damage sustained by a
time of each such flood event on the average equals or exceeds 25 percent of the market value of
the structure before the damage occurred.
Substantial impr°ovemernt means any combination of repairs, reconstruction, rehabilitation,
addition, or other improvement of a structure, taking place during any one year period whereby the
cost of which equals or exceeds 50 percent of the mazlcet 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 any
correction of existing violations of State or Orange County health, sanitary, or safety code specifications
which have been identified by the Orange County code enforcement official and which are the minimum

necessary to further the purposes of this Ordinance,
Variances shall not be issued within any designated floodway or non-encroachment area 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 a 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;
iii, A determination that the granting of a variance will not result in increased flood
heights, additional threats to public safety, or extraordinary public expense, create
nuisance, cause fraud on or victimization of the public, or conflict with existing local
laws or ordinances; and,
iv. That the circumstances on the subject property are unique to the subject
property and not to properties in Eeneral
d. Any applicant to whom a variance is granted shall be given written notice specifying the
difference between the BFE and the 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 reference level elevation. Such notification
shall be maintained with a record of all vaziance actions..
e. The Floodplain Administrator shall maintain the records of all appeal actions and report
any variances to the FEMA and the State ofNorth Carolina upon request,

Ren Ivins, Erosion Control Supervisor
From: Glenn Bowles, Planner II
Date: May 10, 2005
Subject: Structures in Mapped Flood-Prone Areas
With the recent attachrnent of Neuse and Cape Feaz River Basins flood-prone area map
coverages into the Orange County Planning GI5 database, staff is able to access new floodplain
data with our existing GIS parcel and building overlays, The new floodplain data removed some
67 structures in Neuse Basin stream and added 30 other structures, which previously were not
within mapped floodplain azeas, The table below summarizes the type of structure and
construction date, iflmown.
Of the 86 structures in floodplain areas, 45 are houses or manufactured homes, and 41 are
gazages, barns, stables, or other outbuildings. The 86 structures represent about 2% if all Orange
County parcels containing flood prone areas. Of the 45 residences, 34 were built before 1981,
the date the county's flood damage ordinance was first adopted. Three residences have located in
floodplain areas sihce 1994, the date of the county's initial stream buffer ordinance adoption.
New floodplain mapping includes 14 houses, which were not mapped in 1981, For flood
insurance purposes, these residences will be placed in a special category. Only four structures
are located wholely or partially within floodways, two are residences built before 1973 and one
is a state-owned building,
