PURPOSE:
To receive public comment on proposed changes to the Soil Erosion and Sedimentation Control
Ordinance as recommended by the States Division of Land Resources, Land Quality Section.
BACKGROUND:
Orange County has conducted soil erosion and sedimentation control countywide since the
original Ordinance was approved in 1975. Since adoption, the ordinance has been revised 13
times. The first 12 were at the request of the State to match changes to the State's model
ordinance with the last request being in 1992. The thirteenth revision was made in 2003 and
reflects the Commissioner's desire to ban open burning of large woody debris resulting from
land clearing activities subject to the Erosion Control Ordinance.
The current State requested revision is a result of recent changes to the State's model
ordinance. Proposed Changes to the Soil Erosion & Sedimentation Control Ordinance (per
NCDENR) fall under the following headings:
1. Ground Cover
2. Intent
3. Notice of Activity Initiation
4. Precohstruction Conference
5. Required Revisions
6. Civil Penalty Assessment Factors
7. Notice of Civil Penalty Assessment
8. Hearing
9. Final Decision

13.Financial Responsibility and Ownership
14.Land Disturbing Activity
15. Area Inspection
*Note: In the past, civil penalties collected pursuant to the ordinance were credited to the general
fund of the local government as non-tax revenue. The amended ordinance will require that penalties
collected be credited to the Civil Penalty and Forfeiture Fund (Case law on an air quality delegated
program determined that civil penalties assessed by local governments pursuant to a state
delegation had to be remitted to the Civil Penalty and Forfeiture Fund for the benefit of the local
school boards pursuant to the State Constitution's provision on State penalties, fines, and
forfeitures.) Since 1996, Orange County Erosion control has collected approximately $2,000 (all in
1997-98 and from one contractor).
A full copy of the Soil Erosion and Sedimentation Control Ordinance is included as a
separate enclosure. Changes are shown in stril~ethreug# and underline. In addition to the date
change on the header of every page, the following pages contain amendments: cover, i, ii, iii,
14, 16, 21, 28, 29, 34, 35, and 36.
FINANCIAL IMPACT: None. Existing Erosion control staff is currently implementing and
administering the Ordinance.
RECOMMENDATION(S):
The Administration recommends referral to the Planning Board for a recommendation to be
returned to the BOCC no sooner than June 26, 2007.

Orange County SE & SC Ordinance ~ -
WHEREAS, the County Commissioners of Orange County, North Carolina, recognize a great
need to control soil erosion and sedimentation and those activities which result in erosion and
sedimentation within Orange County and within areas affecting the. county; and
WHEREAS, the North Carolina General Assembly, through Chapter 392 of the Session Laws of
North Carolina, 1973, and other laws, has delegated to local governments the power to control
such erosion and sedimentation; and
WHEREAS, Orange County Commissioners desire to exercise such power;
NOW, THEREFORE, BE IT ORDAINED by the County Commissioners of Orange County, North
Carolina.
SECTION 1 TITLE
This Ordinance may be cited as the Orange County Soil Erosion and Sedimentation
Control Ordinance.
SECTION 2 PURPOSES
This Ordinance is adopted for the purposes of:
(1) Regulating the clearing, grading, excavation, filling and manipulation of
the earth and the moving and storing of waters in order to: control and
prevent accelerated soil erosion and sedimentation, prevent the pollution of
water, prevent damage to public and private property, maintain the balance
of nature, prevent the obstruction of natural and artificial drainageways,
inhibit flooding and reduce the undermining of roads and other
transportation facilities.
(2) Establishing procedures through which these purposes can be fulfilled.
Notwithstanding the provisions of Section 5 herein, the Board of County Commissioners
hereby declares its intent that all of the departments and agencies of Orange County, its
contractors and subcontractors shall comply with the regulations set forth in this
Ordinance.
Section 2.1 Windings of Fact Relating to Sedimentation and Erosion in University Lake,
Cane Creek, and Upper Eno Watersheds
The County Commissioners find that, without strict sedimentation and erosion
controls, the development of land within the University Lake, Cane Creek, and
Upper Eno Watersheds will have a significant adverse impact upon the health,
safety, and welfare of all persons served by the water supply reservoirs within
these watersheds. More specifically:
Orange County SE & SC Ordinance SopF.,,'~^~'~, ^""'September 12.20bG
A. Stormwater runoff carries pollutants into water supply reservoirs,
degrading water quality. These pollutants include, but are not limited to,
organic and inorganic chemicals.
B. The increase in nutrients such as phosphorus and nitrogen will accelerate
eutrophication of water supply reservoirs, adversely affecting flora and
fauna.
C. The improper channelization of watercourses and drainage areas in the
University Lake, Cane Creek, and Upper Eno Watersheds will increase the
velocity of runoff, thereby increasing erosion and sedimentation.
D. The alteration of the natural topography and removal of vegetation will
increase erosion by increasing velocity of runoff.
E. The siltation of water bodies resulting from increased erosion will decrease
the capacity of the water bodies to hold and transport water, and harm flora
and fauna.
F. Sedimentation further reduces water quality because it transports pollutants
into the water, then releases them in the water as it settles.
G. Impervious surfaces will increase the volume and rate of stormwater
runoff. This allows less water to percolate into the soil, thereby decreasing
groundwater recharge. Increased velocity of runoff also reduces the
filtering effect of the soil.
H. Improperly managed stormwater runoff will increase the incidence of
flooding and the level of floods which occur.
Section 2.2 Objectives of Regulations Applicable to University Lake, Cane Creek, and
Upper Eno Watersheds
The regulations set forth in this Ordinance applicable to the University Lake, Cane
Creek, and Upper Eno Watersheds are designed:
To protect and maintain the chemical, physical and biological-quality and
integrity of water supply reservoirs within these watersheds and other
critical watershed areas.
2. To prevent harm to the residents of the community by prohibiting activities
which adversely affect water supply reservoirs as a public water supply.
3. To encourage the protection of natural systems and the utilization of these
systems in a manner which does not impair their beneficial functioning.
2
Orange County SE & SC Ordinance °^^'°~.'~°r''-~"~'Seotember 12, 201JG
4. To discourage the construction of drainage systems which do not
functionally approximate the natural drainage pattern.
5. To minimize sedimentation and erosion, within the watershed, and as a
result, minimize the transport of sediment and pollutants to University
Lake.
6. To protect and maintain the existing habitat offish and wildlife.
Z To prevent damage from flooding while recognizing that natural
fluctuations in water levels are beneficial.
8. To protect the absorptive, purifying and retentive functions of the natural
systems existing in the University Lake, Cane Creek, and Upper Eno
Watersheds area.
9. To ensure the attainment of these objectives by requiring the approval and
implementation of sedimentation and Erosion Control Plans for all
activities which may adversely affect the University Lake, Cane Creek, and
Upper Eno Watersheds.
10. To provide and enforce design and performance standards for control of
post-development erosion and sedimentation in order to preserve the
characteristics that existed in the University Lake, Cane Creek, and Upper
Eno Watersheds Area prior to development.

C. Protection of Property
Persons conducting land-disturbing activity shall take all reasonable measures to
protect all public and private property from damage by such activities. This
requirement shall apply to any area to be disturbed.
SECTION 7 BASIC CONTROL OBJECTIVES
An Erosion and Sedimentation Control Plan may be disapproved pursuant Yo Section 18 of
this ordinance if the plan fails to address the following control objectives:
A. Identify Critical Areas
On-site areas which are subject to severe erosion, and off-site areas which are
especially vulnerable to damage from erosion andlor sedimentation, are to be
identified and receive special attention, and appropriate mitigative measures are to be
taken to protect those areas.
B. Plan for Erosion Control
Design the development and prepare the site plan so that the necessary sediment-
trapping devices and erosion control measures can be accommodated and are
accessible for maintenance and removal. Observe the requirements and standards in
Orange County's Soil Erosion and Sediment Control Manual.
C. Limit Exposed Areas. '
All land-disturbing activities are to be planned and conducted to minimize the size of
the area to be exposed at any one time.
D. Limit Time of Exposure
All land-disturbing activities are to be planned and conducted to limit exposure to the
shortest feasible time.
E. Control Surface Water
Surface water runoff originating upgrade of exposed areas should be controlled to
reduce erosion and sediment loss during the period of exposure.
F. Control Sedimentation
All land-disturbing activities are to be planned and conducted so as to prevent off-site
sedimentation damage.
12
Orange County SE & SC Ordinance °°^«°~~~~.,ber'-'-~°"o'~Seotember 12; 20h6
G. Manage Stormwater Runoff
When the increase in the peak rates and velocity of storm water runoff resulting from a
land-disturbing activity is sufficient to cause accelerated erosion of the receiving
watercourse, plans are to include measures to control the velocity and the rate of
release at the point of discharge so as to minimize accelerated erosion of the site and
increased sedimentation of the stream.
H. Open Burning
The Plan should specify the method of disposal of trees, limbs, stumps and
construction debris associated with the activity; which shall be by some method other
than open burning.
SECTION 8 MANDATORY DESIGN AND PERFORMANCE STANDARDS
FOR LAND-DISTURBING ACTIVITY
No land-disturbing activity subject to the control of this Ordinance shall be undertaken
except in accordance with the following mandatory standards:
A. Buffer Zone
No land-disturbing activity during periods of construction or improvement to land
shall be permitted in proximity to a lake or natural watercourse unless a buffer
zone is provided along the margin of the watercourse of sufficient width to confine
visible siltation within the twenty-five percent (25%) of the buffer zone nearest
the land-disturbing activity. Waters that have been classified as trout waters by the
Environmental Management Commission shall have an undisturbed buffer zone 25
feet wide or of sufficient width to confine visible siltation within the twenty-five
percent (25%) of the buffer zone nearest the land-disturbing activity, whichever is
greater. Provided, however, that the County may approve plans which include
land-disturbing activity along trout waters when the duration of said disturbance
would be temporary and the extent of said disturbance would be minimal. This
subdivision shall not apply to aland-disturbing activity in connection with the
construction of facilities to be located on, over, or under a lake or natural
watercourse.
Unless otherwise provided, the width of a buffer zone is measured from the edge
of the water to the nearest edge of the disturbed area, with the 25 percent of the
strip nearer the land disturbing activity containing the natural or artificial means
of confining visible siltation.
2. The 25 footminimum width for an undisturbed buffer zone adjacent to designated
trout waters shall be measured horizontally from the top of the bank.
3. Where a temporary and minimal disturbance is permitted as an exception by
Section 8 (A) (1) of this ordinance, land-dishzrbing activities in the buffer zone
13
Orange County SE & SC Ordinance Se~ter+~ber-16~A83Seotember 12, 20b6
adjacent to designated trout waters shall be limited to a maximum of 10% of the
total length of the buffer zone within the tract to be distributed such that there is
not more than 1001inear feet of disturbance in each 10001inear feet of buffer
zone. Larger areas may be disturbed with the written approval of the Director of
the Division of Land Resources of the Department of Environment, Health, and
Natural Resources.
4. No land-disturbing activity shall be undertaken within a buffer zone adjacent to
designated trout waters that will cause adverse temperature fluctuations, as set
forth in 15 NCAC 2B.0211 Fresh Surface Water Classification and Standards, in
these waters.
B. Graded Slopes and >;Ylls
The angle for graded slopes and fills shall be no greater than the angle which can be
retained by vegetative cover or other adequate erosion control devices or structures. In
any event,,slopes left exposed will; within'~O~~r~:=s 21 calendar days of completion
of any phase of grading, be planted or otherwise provided with ground cover, devices,
or structures sufficient to restrain erosion.
C. Ground Cover
Whenever land-disturbing activity is undertaken on a tract comprising more than
20,000 square feet, if more than 20,000 square feet are uncovered, the person
conducting the land-disturbing activity shall install such sedimentation and erosion
control devices and practices as are sufficient to retain the sediment generated by the
land-disturbing activity within the boundaries of the tract during construction upon
and development of said tract, and shall plant or otherwise provide a permanent
ground cover sufficient to restrain erosion after completion of construction or
development. Except as provided in Section 8 (D) (2) (e) of this ordinance, provisions
for a ground cover sufficient to restrain erosion must be accomplished within 3015
working days or x-28 90 calendar days, whichever period is shorter, following
completion of construction or development.
D. Design and Performance of Control Measures
1. Design Storm
Except as provided in Section 8(D)(2)(b) of this Ordinance and in the standard
for sediment ponds in the Soil Erosion and Sediment Control Manual erosion
and sedimentation control measures, structures, and devices shall be so planned,
designed, and constructed as to provide protection from accelerated erosion and
sedimentation from the calculated maximum peak rates of runoff from the ten-
year frequency storm. Runoff rates shall be calculated using the procedures in
the USDA Soil Conservation Service's "National Engineering Field Manual for
Conservation Practices," or other calculation procedures acceptable to the
Erosion Control Officer.

Orange County SE & SC Ordinance °^^«^~P.~~.,be: '-.~=6'B~September 12.20tJ6
2. Standards for High Quality Waters
In High Quality Water (HQW) zones the following design standards shall apply:
a. Uncovered areas in HQW zones shall be limited at any time to a
maximum total area of 20 acres within the boundaries of the tract.
Only the portion of the land-disturbing activity within a HQW zone
shall be governed by this section. Larger areas may be uncovered
within the boundaries of the tract with the written approval of the
Director of the Division of Land Resources of the Department of
Environment, Health, and Natural Resources.
Erosion and sedimentation control measures, structures, and devices
within HQW zones shall be so planned, designed, and constructed
to provide protection from the runoff of the 25-year storm which
produces the maximum peak rate of rnnoff. The peak rate of runoff
shall be calculated according to procedures in the United States
Department of Agriculture Soil Conservation Service's National
Engineering Field Manual for Conservation Practices or according
to procedures adopted by any other agency of this state or the
United States or any generally recognized organization or
association.
c. Sediment ponds (also called "sediment basins") within HQW zones
shall be designed and constructed such that the pond will have a
settling efficiency of at least 70% for the 40 micron (0.04 mm) size
soil particle transported into the basin by the runoff of that 2-year
storm which produces the maximum peak rate of runoff The peak
rate of runoff shall be calculated according to procedures in the
United States Department of Agriculture Soil Conservation
Service's National Engineering Field Manual for Conservation
Practices or according to procedures adopted by any other agency
of this state or the United States or any generally recognized
organization or association.
d. Newly constructed open channels in HQW zones shall be designed
and constructed with side slopes no steeper than 2 horizontal to 1
vertical if a vegetative cover is used fox stabilization unless soil
conditions permit a steeper slope or where the slopes are stabilized
by using mechanical devices, structural devices or other acceptable
devices. In any event, the angle for side slopes shall be sufficient to
restrain accelerated erosion.
e. Ground cover sufficient to restrain erosion must be provided for
any portion of a land disturbing activity in a HQW zone within 15
working days or 60 calendar days, whichever period is shorter,
following completion of construction or development.

Orange County SB & SC Ordinance °°^`^^~^03~tember 12 20~J6
E. Prior Plan Approval
No person shall initiate any land-disturbing activity on a tract if more than 20,000
square feet are to be uncovered unless, thirty or more days prior to initiating the
activity, an erosion and sedimentation control plan for such activity is filed with,
approved by, and a Land Disturbing Permit obtained from the County.
F The land-disturbing activity shall be conducted in accordance with the approved
erosion and sedimentation control plan.
Section 8.1 Additional Standards for Land-Disturbing Activity in University Lake,.
Cane Creek, and Upper Eno Watersheds
The provisions of Section 8 shall apply to land-disturbing activity within the University
Lake, Cane Creek, and Upper Eno Watersheds. In addition, the design, construction, and
maintenance of drainage systems in developments within the University Lake, Cane
Creek, and Upper Eno Watersheds shall also be consistent with the following standards,
and these standards shall control to the extent that they are more restrictive than those set
forth in Section 8.
Channeling Runoff -channeling runoff directly into water bodies shall be prohibited.
Runoff shall be routed through swales and other systems designed to increase time of
concentration, decrease velocity, increase infiltration, allow suspended solids to settle, and
remove pollutants.
Alteration of Watercourses -natural watercourses shall not be dredged, cleared of
vegetation, deepened, widened, straightened, Stabilized or otherwise altered except in
accordance with an approved Erosion Control Plan. Water shall be retained or. detained
before it enters any natural watercourse in order to preserve the natural hydro-dynamics of
the watercourse and to prevent sedimentation.
Limit Land-Disturbing Activity -the area of disturbance by development shall be as
small as practical.
Land Alterations - no grading, cutting or filling shall be commenced until erosion and
sedimentation control devices have been installed between the disturbed area and water
bodies, watercourses, wetlands, or adjoining properties.
Wetland Protection -wetlands and other water bodies shall not be used as sediment traps
during development.
Maintenance Requirements and Responsibility -erosion and sedimentation facilities
shall receive regular maintenance to ensure that they continue to function properly.
Temporary basins shall be cleaned out when they are filled to fifty (50) percent of their
design capacity.
16
Orange County SE & SC Ordinance ~°^~°^'°^0~'September 12.20b6
Artificial Watercourses -any artificial watercourse (where the need is demonstrated)
shall be designed considering soil type so that the velocity of flow is low enough to
prevent accelerated erosion.
Buffer Area Requirements -soil and pollutants tamed overland, primarily from roads,
trails, andlor land-disturbing activities, can be effectively trapped by leaving a relatively
undisturbed strip of vegetation parallel and adjacent to the watercourse. Properly managed
overland water flow can be directed into this buffer area in a manner that will reduce
velocity and cause dispersion of the water. Sediments carried by the water will settle out
as a result of this slowing and dispersion process. The width of these buffer areas shall
depend on the type of stream or drainage area. The width of the buffer strips shall be as
follows:
Creeks and tributaries - (i.e., permanent streams flowing directly into a
water supply reservoir within University Lake, Cane Creek, and Upper
Eno Watersheds and permanent streams flowing into such streams).
Measure along a line running perpendicular to the edge of the floodplain
(or if no floodplain has been demarcated, the center of the stream) fifty
feet from the edge of the floodplain (or if no flood plain has been
demarcated from the edge of the water) plus an additional distance equal
to:
4 x slope x 100
where "slope" is expressed as a percentage derived by dividing by 100 the
rise in elevation between the floodplain boundary line (or if no floodplain
has been demarcated, the centerline of the watercourse) and a point one
hundred feet from that point along the above described perpendicular line.
2, Intermittent streams flowing into creeks and tributaries. Measure along a
line running perpendicular to the centerline of the intennittent stream fifty
feet from such stream centerline.
3. Intermittent streams flowing directly into water supply reservoirs within
University Lake, Cane Creek, and Upper Eno Watersheds. Measure along
a line running perpendicular to the centerline of the intermittent stream
one hundred feet from such stream centerline.
4. Intermittent streams flowing into streams which flow directly into water
supply reservoirs within University Lake, Cane Creek, and Upper Eno
Watersheds. Measure along a line running perpendicular to the centerline
of the intermittent stream fifty feet from such stream centerlines.
5. Water supply reservoirs within University Lake, Cane Creek, and Upper
Eno Watersheds. Measure along a line running perpendicular to the high
water mark or floodplain boundary (whichever is fartherfi•om the Lake)
one hundred feet from such high water mark or floodplain boundary
(whichever is farther from the Lake) plus an additional distance equal to:
17
Orange County SE & SC Ordinance Septetnb^~ ",'^^'Septetnber 12, 20h6
4 x slope x 100
where "slope" is expressed as a percentage derived by dividing by 100 the
rise in elevation between the high water line of the Lake and a point one
hundred feet from that point along the above described perpendicular line.
The existing natural vegetation in the designated buffer areas shall not be
disturbed in any way that would reduce the area's effectiveness in
achieving the objectives set forth in this subsection. In addition, buffer
areas from which the vegetative cover has been removed shall be planted
or otherwise provided with ground cover devices or structures sufficient to
allow the buffer area to accomplish the objectives set forth in this
subsection. Buffers shall not be used as temporary erosion control devices
during construction.
Sediment Storage -sediment shall be retained on the site of the development
Detention or Retention Areas -retention and detention ponds may be used to retain and
detain the increased and accelerated runoff which the development generates. Water shall
be released from detention ponds into watercourses or wetlands at a rate and in a manner
approximating the natural flow which would have occurred before development.
Retention and detention ponds shall be designed so that they maintain their structural
integrity when subject to a 100-year storm. Detention and retention areas shall be
designed so that shorelines are sinuous rather than straight and so that the length of the
shoreline is maximized, thus offering more space for the growth of littoral vegetation. The
banks of detention and retention areas shall slope at a gentle grade into the water as a
safeguard against drowning, personal injury or other accidents, to encourage the growth of
vegetation and to allow the alternate flooding and exposure of the areas along the
shoreline as water levels periodically rise and fall.
Open Space -the use of drainage facilities and vegetated buffer zones as open space,
recreation, and conservation areas shall be encouraged.
Recreational activities undertaken in these open space areas shall be limited to passive or
leisure activities.
Grassed Swales -drainage within the development shall be accommodated by the natural
drainage systems whenever possible. The use of grassed drainageways to channel water
shall be encouraged. The velocity of travel in this grassed swale shall range between 2-4
feetlsecond.
Retention of Runoff from Industrial Sites - On sites developed for industrial purposes
(i.e., uses involving the manufacturing, processing, creating, repairing, renovating,
painting, cleaning, or assembly of goods, merchandise, or equipment), retention or
detention areas meeting the standards set forth in subsection j. shall be used to insure that
18
Orange County SE & SC Ordinance °^^ °~~.,.,~^r '-'-z"~'September 12.206
runoff is retained on the site before being released. The purpose of this requirement is to
insure that, not only will the standard set forth in subsection 9A, be met, but also a
mechanism will be provided to safeguard the watershed against the spillage of toxic or
dangerous substances.
SECTION 9 STORMWATER OUTLET PROTECTION
A. Control of Discharge in University Lake, Cane Creek, and Upper Eno
Watersheds
Provisions shall be made for the control of stormwater discharges for the types of
development as specified below. After development of the site, the peak discharge of
stormwater runoff resulting from aten-year storm shall be no greater than that which
would result from aten-year storm on the same site prior to.development.
This requirement shall apply to:
• Commercial, industrial, office, and institutional developments
• Multi-family residential developments of more than 10 units
• Single-family detached residential developments where more than 3 lots are to be
created.
B. Control of Velocity
Persons shall plan and conduct land-disturbing activity so that the post-construction
velocity of the 10-year storm runoff in the receiving watercourse to the discharge point
does not exceed the greater of:
• The velocity established by the table in paragraph 3 of the subsection; or
• The velocity of the 10-year storm runoff in the receiving watercourse prior to
development.
If conditions (1) or (2) of this paragraph cannot be met, then the receiving watercourse to
and including the discharge point shall be designed and constructed to withstand the
expected velocity anywhere the velocity exceeds the "prior. to development" velocity by
10%.
C. Standards
L Acceptable Management Measures
Measures applied alone or in combination to satisfy the intent of this subchapter
are acceptable if there are no objectionable secondary consequences. Innovative
techniques and ideas will be considered and may be used when shown to have the
potential to produce successful results. Some alternatives are to:
19
c ..«e..,r.e. i < nnnaSeptember 12.201)6
Orange County SE & SC Ordinance °°~ •••°-~°
• Avoid increases in surface runoff volume and velocity by including measures
to promote Infiltration to compensate for increased runoff from areas rendered
impervious;
• Avoid increases in stormwater discharge velocities by using vegetated or
roughened swales and waterways in lieu of closed drains and high velocity
paved sections;
• Provide energy dissipaters at outlets of storm drainage facilities to reduce flow
velocities to the point of discharge; these may range from simple rip-rapped
sections to complex structures;
• Protect watercourses subject to accelerated erosion by improving cross sections
and/or providing erosion-resistant lining.
2. Exceptions
This rule shall not apply in areas other than the University Lake, Cane Creek, and
Upper Eno Watersheds where it can be demonstrated that storm water discharge
velocities will not create an erosion problem in the receiving watercourse.

extent and duration of disturbance of the stream channel. The relocation of a stream,
where relocation is an essential part of the proposed activity, shall be planned and
executed so as to minimize changes in the stream flow characteristics except when
justification for significant alteration to flow characteristics is provided. Every effort shall
be made to maintain buffer zones consisting of existing vegetation between the land-
disturbing activity and the watercourse.
SECTION 13 RESPONSIBILITY FOR INSTALLATION AND
MAINTENANCE
During the development of a site, the person engaged in or conducting the land-disturbing
activity shall be responsible for installing and maintaining all temporary and permanent
erosion and sedimentation control measures and facilities as required by the approved or
revised Erosion Control Plan, any provision of the Ordinance, the Act, or any order
adopted pursuant to this Ordinance or the Act. The responsibility for installing and
maintaining permanent erosion and sedimentation control measures and facilities after
completion of the site development shall lie with the land owner or person in possession
or control of the land except facilities and measures installed within road or streetrights-
of-way or easements accepted for maintenance by a government agency.

Plan is approved or prior to the start of the land disturbance. Every Grading Permit
issued shall expressly prohibit open burning of trees, limbs, stumps and construction
debris associated with the permitted activity.
D. Expiration of Permits
Plan Approvals
The County may establish an expiration date for Erosion Control Plans approved
under this Ordinance. Erosion Control Plan Approvals expire eighteen (18) months
after the approval date unless the land disturbance is started as defined below.
Land Disturbing Permits
A Land Disturbing Permit must be obtained before beginning the disturbance and may
be obtained at any time as long as the Plan Approval is valid. Land Disturbing Permits
expire with the expiration of the Plan Approval unless the disturbance is begun. Once
the disturbance begins, a Land Disturbing Permit is valid for a period of two (2) years
starting with the commehcement of the disturbance, as defined below. The Land
Disturbing Permit must be renewed if the disturbance continues more than two years.
The renewal fee is one half the original fee and is valid for one year.
Start of Activity
For the purpose of determining the expiration date of the plan approval and Land
Disturbing Permit, the land-disturbing activity is considered to have started when the
pre-construction conference has been held, the necessary erosion control practices
have been properly installed and the site clearing or grading has begun.
E. Fees
The County may establish such fees as considered necessary to defray costs of
administering this Ordinance.
F. Building Permits

G. Revocation of Land Disturbing Permit
Whenever a person conducting aland-disturbing activity is not complying with the
provisions of this Ordinance, the Land Disturbing Permit, the Approved Erosion
Control Plan or any amendments to the Plan, the Erosion Control Officer may revoke
the Land Disturbing Permit for the site. Notice of Revocation shall be sent by
registered or certified mail to the person conducting the land-disturbing activity. In the
event delivery cannot be accomplished by registered or certified mail, it may be
accomplished in any manner provided in Rule 4 (j) of the North Carolina Rules of
Civil Procedure. Upon receipt of the Revocation Notice, the person responsible must
immediately order all land-disturbing activities to cease except those which are
specifically directed towards bringing the site into compliance. Once the site has been
inspected and remedial work approved by the Erosion Control Division, the
responsible party may reapply for a Land Disturbing Permit and pay the appropriate

Recommendations

• Refer to the Planning Board for recommendation
• Return recommendation to the BOCC no sooner than June 26, 2007
Commissioner Jacobs asked Geof Gledhill about Civil Penalties Assessment Factors
and said that there does not seem to be any place for the local government to recover the costs
incurred in pursuing the enforcement option. Geof Gledhill said that itis not allowed. The North
Carolina Supreme Court has decided that all fines and forfeitures go to the schools.
Jay Bryan asked Terry Hackett if there were enough people to do the work to support
the revisions. Terry Hackettsaid that he thinks so, but there is a little bit of a push. There may
need to be additional staff at some point in the future.
There was no public comment.
A motion was made by Commissioner Nelson, seconded by Commissioner Jacobs to
refer to the Planning Board for a recommendation to be returned to the BOCC no sooner than
