16-5 Mandatory 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
(1) Standard Buffer. 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.
i. Projects On, Over or Under Water. This subdivision shall not apply to a land -
disturbing activity in connection with the construction of facilities to be located
on, over, or under a lake or natural watercourse.
ii. Buffer Measurement. Unless otherwise provided, the width of a buffer zone is
measured horizontally 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 natural or artificial means of confining visible siltation.
(b) Graded Slopes and Fills. The angle for graded slopes and fills shall be no greater than the
angle that can be retained by vegetative cover or other adequate erosion control devices
or structures. In any event, slopes left exposed will, within 21 calendar days of
completion of any phase of grading, be planted or otherwise provided with temporary or
permanent ground cover, devices, or structures sufficient to restrain erosion. The angle
for graded slopes and fills must be demonstrated to be stable. Stable is the condition
where the soil remains in its original configuration, with or without mechanical
constraints.
(c) Fill Material. Unless a permit from the Department's Division of Waste Management to
operate a landfill is on file for the official site, acceptable fill material shall be free of
organic or other degradable materials, masonry, concrete and brick in sizes exceeding
twelve (12) inches, and any materials which would cause the site to be regulated as a
landfill by the State of North Carolina.
(d) Ground Cover. Whenever land -disturbing activity that will disturb more than 10,000
16-6
square feet is undertaken on a tract, the person conducting the land -disturbing activity
shall install erosion and sedimentation control devices and practices that 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 16-8(b)(5) of this ordinance,
provisions for a ground cover sufficient to restrain erosion must be accomplished within
15 working days or 90 calendar days following completion of construction or
development, whichever period is shorter.
(e) Prior Plan Approval. No person shall initiate any land -disturbing activity that will disturb
more than 10,000 square feet on a tract unless, thirty (30) or more days prior to initiating
the activity; a Plan for the activity is filed with and approved by the City of Archdale. An
erosion and sedimentation control plan may be filed less than 30 days prior to initiation
of a land -disturbing activity if the plan is submitted under an approved express permit
program, and the land -disturbing activity may be initiated and conducted in accordance
with the plan once the plan has been approved. The City of Archdale shall forward to the
Director of the Division of Water Quality a copy of each Plan for a land -disturbing
activity that involves the utilization of ditches for the purpose of de -watering or lowering
the water table of the tract.
(f) The land -disturbing activity shall be conducted in accordance with the approved erosion
and sedimentation control plan.
Sec. 16-6. Erosion and Sedimentation Control Plans
(a) Plan Submission. A Plan shall be prepared for all land -disturbing activities subject to this
ordinance whenever the proposed activity will disturb more than 10,000 square feet on a
tract. Three (3) copies of the Plan shall be filed with the City of Archdale, a copy shall
be simultaneously submitted to any Soil and Water Conservation District at least 30 days
prior to the commencement of the proposed activity.
(b) Financial Responsibility and Ownership. Plans may be disapproved unless accompanied
by an authorized statement of financial responsibility and ownership. This statement
shall be signed by the person financially responsible for the land -disturbing activity or his
attorney in fact. The statement shall include the mailing and street addresses of the
principal place of business of (1) the person financially responsible, (2) the owner of the
land, and (3) any registered agents. If the person financially responsible is not a resident
of North Carolina, a North Carolina agent must be designated in the statement for the
purpose of receiving notice of compliance or non-compliance with the Plan, the Act, this
ordinance, or rules or orders adopted or issued pursuant to this ordinance. If the applicant
is not the owner of the land to be disturbed, the draft erosion and sedimentation control
plan must include the owner's written consent for the applicant to submit a draft erosion
and sedimentation control plan and to conduct the anticipated land -disturbing activity.
(c) Environmental Policy Act Document. Any Plan submitted for a land -disturbing activity
16-7
for which an environmental document is required by the North Carolina Environment
Policy Act (G.S. 113A-1, et seq.) shall be deemed incomplete until a complete
environmental document is available for review. The City of Archdale shall promptly
notify the person submitting the Plan that the 30-day time limit for review of the Plan
pursuant to this ordinance shall not begin until a complete environmental document is
available for review.

submit any comments and recommendations to the City of Archdale within 20 days after
the District received the Plan, or within any shorter period of time as may be agreed upon
by the District and the City of Archdale. Failure of the District to submit its comments
and recommendations within 20 days or within any agreed -upon shorter period of time
shall not delay final action on the Plan.
(f) Timeline for Decisions on Plans. The City of Archdale will review each complete Plan
submitted to them and within 30 days of receipt thereof will notify the person submitting
the Plan that it has been approved, approved with modifications, approved with
performance reservations, or disapproved. Failure to approve, approve with
modifications, or disapprove a complete Plan within 30 days of receipt shall be deemed
approval. The City of Archdale will review each revised Plan submitted to them and
within 15 days of receipt thereof will notify the person submitting the Plan that it has
been approved, approved with modifications, approved with performance reservations, or
disapproved. Failure to approve, approve with modifications, or disapprove a revised
Plan within 15 days of receipt shall be deemed approval.
(g) Approval. The City of Archdale shall only approve a Plan upon determining that it
complies with all applicable State and local regulations for erosion and sedimentation
control. Approval assumes the applicant's compliance with the federal and state water
quality laws, regulations and rules. The City of Archdale shall condition approval of
Plans upon the applicant's compliance with federal and state water quality laws,
regulations and rules. The City of Archdale may establish an expiration date, not to
exceed three (3) years, for Plans approved under this ordinance.

For purposes of this subsection, an applicant's record may be considered for only the two
years prior to the application date.
In the event that a Plan is disapproved pursuant to this subsection, the City of Archdale
shall notify the Director of such disapproval within ten (10) days. The City of Archdale
shall advise the applicant and the Director in writing as to the specific reasons that the
Plan was disapproved.
(j) Notice of Activity Initiation. No person may initiate a land -disturbing activity before
notifying the agency that issued the Plan approval of the date that land -disturbing activity
will begin.
(k) Preconstruction Conference. When deemed necessary by the approving authority a
preconstruction conference may be required.
(1) Display of Plan Approval. A Plan approval issued under this article shall be prominently
displayed until all construction is complete, all permanent sedimentation and erosion
control measures are installed and the site has been stabilized. A copy of the approved
plan shall be kept on file at the job site.
(m)Required Revisions. After approving a Plan, if the City of Archdale either upon review
of such Plan or on inspection of the job site, determines that a significant risk of
accelerated erosion or off -site sedimentation exists, the City of Archdale shall require a
revised Plan. Pending the preparation of the revised Plan, work shall cease or shall
continue under conditions outlined by the appropriate authority. If following
commencement of a land -disturbing activity pursuant to an approved Plan, the City of
Archdale determines that the Plan is inadequate to meet the requirements of this
ordinance, the City of Archdale may require any revision of the Plan that is necessary to
16-9
comply with this ordinance.
(n) Amendment to a Plan. Applications for amendment of a Plan in written and/or graphic
form may be made at any time under the same conditions as the original application.
Until such time as said amendment is approved by the City of Archdale, the land -
disturbing activity shall not proceed except in accordance with the Plan as originally
approved.
(o) Failure to File a Plan. Any person engaged in land -disturbing activity who fails to file a
Plan in accordance with this ordinance, or who conducts a land -disturbing activity except
in accordance with provisions of an approved Plan shall be deemed in violation of this
ordinance.
(p) The landowner, the financially responsible party, or the landowner's or the financially
responsible party's agent shall perform an inspection of the area covered by the plan after
each phase of the plan has been completed and after establishment of temporary ground
cover in accordance with G.S. 113A-57(2). The person who performs the inspection shall
maintain and make available a record of the inspection at the site of the land -disturbing
activity. The record shall set out any significant deviation from the approved erosion
control plan, identify any measures that may be required to correct the deviation, and
document the completion of those measures. The record shall be maintained until
permanent ground cover has been established as required by the approved erosion and
sedimentation control plan. The inspections required by this subsection shall be in
addition to inspections required by G.S. 113A-61.1.
(q) When deemed necessary by the approving authority, a Surety Bond or Letter of Credit to
cover cost of stabilizing the site may be required.
Sec. 16-7. Basic Control Objectives
An erosion and sedimentation control Plan may be disapproved 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 and/or sedimentation, are
to be identified and receive special attention.
(b) Limit Time of Exposure - All land -disturbing activities are to be planned and conducted
to limit exposure to the shortest feasible time.
(c) Limit Exposed Areas - All land -disturbing activity is to be planned and conducted to
minimize the size of the area to be exposed at any one time.
(d) 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.
16 - 10
(e) Control Sedimentation - All land -disturbing activity is to be planned and conducted so as
to prevent off -site sedimentation damage.
(f) Manage Storm Water Runoff - When the increase in the velocity of storm water runoff
resulting from a land -disturbing activity is sufficient to cause accelerated erosion of the
receiving watercourse, a Plan is to include measures to control the velocity to the point of
discharge so as to minimize accelerated erosion of the site and increased sedimentation of
the stream.
Sec. 16-8. Design and Performance Standards
(a) Except as provided in 16-8(b)(2) of this ordinance, erosion and sedimentation control
measures, structures, and devices shall be planned, designed, and constructed to provide
protection from the calculated maximum peak rate of runoff from the ten-year 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
acceptable calculation procedures.
(b) HQW Zones. In High Quality Water (HQW) zones the following design standards shall
apply:
(1) Limit on Uncovered Area. Uncovered areas in HQW zones shall be limited at any
time to a maximum total area of twenty 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.
(2) Maximum Peak Rate of Runoff Protection. Erosion and sedimentation control
measures, structures, and devices within HQW zones shall be planned, designed and
constructed to provide protection from the runoff of the twenty-five year storm which
produces the maximum peak rate of runoff as 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.
(3) Settling Efficiency. Sediment basins within HQW zones shall be designed and
constructed such that the basin will have a settling efficiency of at least 70% for the
40 micron (0.04 millimeter) size soil particle transported into the basin by the runoff
of that two year storm which produces the maximum peak rate of runoff as 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.
(4) Grade. Newly constructed open channels in HQW zones shall be designed and
16 - 11
constructed with side slopes no steeper than two horizontal to one vertical if a
vegetative cover is used for stabilization unless soil conditions permit a steeper slope
or where the slopes are stabilized by using mechanical devices, structural devices or
other acceptable ditch liners. In any event, the angle for side slopes shall be sufficient
to restrain accelerated erosion.
(5) Ground Cover. 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 following completion of construction or development, whichever
period is shorter.
Sec. 16-9. Storm Water Outlet Protection
(a) Intent. Stream banks and channels downstream from any land disturbing activity shall be
protected from increased degradation by accelerated erosion caused by increased velocity
of runoff from the land disturbing activity.
(b) Performance standard. Persons shall 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:
(1) the velocity established by the Maximum Permissible Velocities Table set out within
this subsection; or
(2) the velocity of the ten-year storm runoff in the receiving watercourse prior to
development.
If condition (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%.
Maximum Permissible Velocities Table

Source - Adapted from recommendations by Special Committee on Irrigation Research,
American Society of Civil Engineers, 1926, for channels with straight alignment. For
sinuous channels, multiply allowable velocity by 0.95 for slightly sinuous, by 0.9 for
moderately sinuous channels, and by 0.8 for highly sinuous channels.
(c) Acceptable Management Measures - Measures applied alone or in combination to satisfy
the intent of this section are acceptable if there are no objectionable secondary
consequences. The City of Archdale recognizes that the management of storm water
runoff to minimize or control downstream channel and bank erosion is a developing
technology. Innovative techniques and ideas will be considered and may be used when
shown to have the potential to produce successful results. Some alternatives, while not
exhaustive, are to:
(1) Avoid increases in surface runoff volume and velocity by including measures to
promote infiltration to compensate for increased runoff from areas rendered
impervious;
(2) Avoid increases in storm water discharge velocities by using vegetated or roughened
swales and waterways in place of closed drains and high velocity paved sections:
(3) Provide energy dissipators at outlets of storm drainage facilities to reduce flow
velocities to the point of discharge;
(4) Protect watercourses subject to accelerated erosion by improving cross sections
and/or providing erosion -resistant lining; and
(5) Upgrade or replace the receiving device structure, or watercourse such that it will
receive and conduct the flow to a point where it is no longer subject to degradation
from the increased rate of flow or increased velocity.
(d) Exceptions - This rule shall not apply where it can be demonstrated to the City of
Archdale that storm water discharge velocities will not create an erosion problem in the
receiving watercourse.
16 - 13
Sec. 16-10. Borrow and Waste Areas
When the person conducting the land -disturbing activity is also the person conducting the
borrow or waste disposal activity, areas from which borrow is obtained and which are not
regulated by the provisions of the Mining Act of 1971, and waste areas for surplus materials
other than landfills regulated by the Department's Division of Waste Management shall be
considered as part of the land -disturbing activity where the borrow material is being used or from
which the waste material originated. When the person conducting the land -disturbing activity is
not the person obtaining the borrow and/or disposing of the waste, these areas shall be
considered a separate land -disturbing activity.
Sec. 16-11. Access and Haul Roads
Temporary access and haul roads, other than public roads, constructed or used in connection with
any land -disturbing activity shall be considered a part of such activity.
Sec. 16-12. Operations in Lakes or Natural Watercourses
Land disturbing activity in connection with construction in, on, over, or under a lake or natural
watercourse shall minimize the extent and duration of disruption of the stream channel. Where
relocation of a stream forms an essential part of the proposed activity, the relocation shall
minimize unnecessary changes in the stream flow characteristics.
Sec. 16-13. Responsibility for Maintenance
During the development of a site, the person conducting the land -disturbing activity shall install
and maintain all temporary and permanent erosion and sedimentation control measures as
required by the approved plan or any provision of this Ordinance, the Act, or any order adopted
pursuant to this ordinance or the Act. After site development, the landowner or person in
possession or control of the land shall install and/or maintain all necessary permanent erosion
and sediment control measures, except those measures installed within a road or street right-of-
way or easement accepted for maintenance by a governmental agency.
Sec. 16-14. Additional Measures
Whenever the City of Archdale determines that significant erosion and sedimentation is
occurring as a result of land -disturbing activity, despite application and maintenance of
protective practices, the person conducting the land -disturbing activity will be required to and
