applicable density and stormwater runoff control requirements, the built -upon areas are designed and sited to
minimize stormwater runoff impact to the receiving waters and minimize concentrated stormwater flow, the
remainder of the tract remains in a vegetated or natural state, and the stream buffering requirements found in
Section 7-1.9 are met.
(Amd. of 4-21-05)
7-1.8. Drainage.
The design of storm drainage systems and plans, including calculations, shall clearly indicate the
easements or dedicated areas required for the construction and maintenance of the drainage system.
(A) General Drainage Requirement:
I) All watercourses which carry concentrated drainage from a public road or have a two
acre or larger drainage basin, shall be treated in one or more of the four ways listed in
Section 7-1.8(B), (C), (D) and (E) which follow. The Technical Review Committee when
applicable or Enforcement Officer shall approve the treatments to be used when deemed
compliant with the requirements of the subsections which follow. Open drainage channel
requirements shall be based upon a minimum of one hundred -year storm, and enclosed
systems shall be based upon a minimum of ten-year storm. If the channel is a perennial or
intermittent stream, is identified on the adopted open space plan map or drains a one
hundred twenty (120) acre or larger basin, the determination of drainage treatment shall
be made by the Technical Review Committee when applicable or the Enforcement
Officer. In making this determination the following factors shall be considered before
selecting the appropriate method(s) listed in the subsections which follow:
a) The type of development;
b) The treatment employed by nearby developments;
c) The probability of creation of drainageway and open space;
d) The probability of the creation of future maintenance problems;
e) The probability of erosion or flooding problems; and
f) The adopted open space plan.
g) NPDES Phase II requirements, stream buffer requirements, and channelization
limitations for the WCA and GWA, as described in Article VII (Environmental
Standards).
2) If the channel is not a perennial or intermittent stream, or is not identified on the open
space plan and drains less than a one hundred twenty (120) acre drainage basin, the
determination of drainage treatment shall be made in a manner consistent with this
Section.
(B) Enclosed Subsurface Drainage and requirement for a Drainage or Drainage Maintenance and
Utility Easement:
1) This Section applies to enclosed subsurface drains. Profiles and enclosure standards shall
be in accordance with the Guilford County Storm Sewer Design Manual.
2) A drainage maintenance and utility easement (DMUE) or drainage easement designed to
accommodate stormwater shall be placed on a recorded plat when determined necessary
by the Jurisdiction. The required easement shall be centered on the enclosure when
practical, but in no case shall the outside wall of the enclosure be located less than five
(5) feet from the edge of the easement. The easement shall be of a width determined
necessary for maintenance purposes by the Jurisdiction based upon enclosure depth,
topography and location of existing and proposed improvements, but no less than fifteen
(15) feet.
3) The DMUE or drainage easement shall be kept free and clear of any buildings or other
improvements which would interfere with the proper maintenance of the underground
enclosures. The Jurisdiction shall not be liable for damages to any improvement located
within DMUE area caused by maintenance of utilities located therein. Furthermore,
DMUE may be used for future installations of any underground utility, provided that:
a) Any underground utility to be installed by any utility provider other than the
Jurisdiction shall be subject to approval.
b) Any government agency, public utility, or private company installing additional
underground lines after development has been completed by the owner of the
property shall be responsible for the replacement of all fencing, pavement and
grassed area disturbed by such installation.
c) The Jurisdiction shall not be responsible for damages caused by installation of
additional lines by any public or private utility company.
(C) Open Channel Drainage in Dedicated Drainageway and Open Space Area (Public Open Space):
1) This Section applies to an open channel in a dedicated drainageway and open space area.
The drainageway and open space area shall be dedicated by a recorded plat and shall be
labeled "Dedicated to Guilford County and the public for Drainageway and Open Space".
This is a voluntary option available in lieu of 7-1.8(D) which enables one to utilize
cluster options and reduce lot sizes when abutting public open space. The ownership of
the dedicated land remains with the deeded owner, but the use is restricted. Dedication
does not transfer title. The dedicated area can also be deeded to any individual or group,
such as a homeowners association or to Guilford County (with Board of Commissioner
acceptance). A previously dedicated area may be considered for development through
approval from TRC and re -platting.
2) The voluntarily dedicated drainage -way and open space area along any stream that drains
a 120 acre or larger drainage basin shall include the land between the natural one hundred
(100) year flood contour lines as determined by FEMA or by calculations approved by
the US Army Corps of Engineers. (Caution: Other Environmental Regulations or federal
wetland regulations will prohibit or restrict fill placement in certain locations.) An area
within the floodway fringe can be developed as permitted in Section 7-5.8 with a
Floodplain Development Permit. The remainder shall be dedicated as indicated in
subsection 1) above.
3) In case of severe topography, additional width may be needed to assure reasonable ease
of maintenance.
4) Adequate access to the public open space shall be provided by means of the dedicated
area abutting public right-of-way or by appropriately spaced access easements no less
than twenty (20) feet in width. If existing access from adjacent areas is deemed sufficient,
no new access shall be required.
5) The centerline of the drainage channel that drains a one hundred twenty (120) acre or
larger drainage basin shall be located no less than fifty (50) feet from any street or
property line provided that the dimensions of the drainage way and open space area
conform to all other requirements of this Section
6) Public open space shall be left in its natural condition or graded to a section approved by
the Jurisdiction which will allow economical and efficient maintenance and shall be
stabilized with permanent vegetative cover.
(D) Open Channel Drainage and requirement for Drainageway and Open Space Easement (Private
Open Space):
1) This Section applies requirements to an open channel meeting one or more of the
descriptions in 7.1.8(A). At the time of plat recordation an easement for the drainage -way
and open space shall be provided and shall be labeled "Drainageway and Open Space
Easement". The drainage -way and open space easement shall include the drainage channel
and the one -hundred -year regulatory floodplain contour as shown on the effective Flood
Insurance Rate Maps or by calculations approved by the US Army Corps of Engineers.
2) Drainageway and open space shall be left in its natural condition or graded to a section
approved by the Jurisdiction which will allow economical and efficient maintenance and
shall be stabilized with permanent vegetative cover.
(E) Open Channel Drainage and requirement for a Drainage or Drainage Maintenance and Utility
Easement:
1) This Section applies to open channels on private property within a drainage or drainage
maintenance and utility easement.
2) The drainage or drainage maintenance and utility easement shall be a minimum total
width of no less than specified below.

The easement width shall be centered on the drainage channel, unless the Technical
Review Committee when applicable or the Enforcement Officer approves other easement
alignments because of topographic conditions. Cases in which the drainage channel flows
into an impoundment, the easement shall extend over and twenty (20) feet beyond the
normal water level of the impoundment or meet the minimum width as specified above,
whichever is greater. Concentrated drainage from less than a two (2) acre drainage basin,
exiting a public right-of-way, shall be as conveyed into a drainage easement as specified
below:
a) Thirty (30) feet wide for the length of channel for concentrated flow exiting
public right-of-way into a defined channel.
b) Minimum thirty (30) feet wide by fifty (50) feet in length for concentrated flow
exiting public right-of-way onto terrain with no pronounced drainage features
3) In case of severe topography, additional width may be required to assure reasonable ease
of maintenance.
4) The easement topography may be modified if permitted under other applicable local and
state regulations (stream buffer, NC Division of Water Quality 401/U.S. Army Corps of
Engineers 404, etc.). In such cases, the approved typical required drainage channel
section shall include the necessary channel to accommodate a one hundred (100) year
flood event and be in accordance with the Guilford County Storm Sewer Design Manual.
The area outside of the required drainage channel may be filled; but any resulting slope
shall be no steeper than two (2) feet horizontal to one (1) foot vertical, unless the slope is
protected by masonry paving, rip -rap, or other material which meets the Jurisdiction's
specifications. If the channel has been altered such that the design flow cannot be
contained within the recorded easement, a corrected easement shall be recorded to show
the altered location and width.
5) If the Technical Review Committee determines suitable access to the easement is not
otherwise provided, access shall be guaranteed by a suitably located access easement
which shall be no less than twenty (20) feet in width.
6) It shall be the responsibility of the owner to maintain all drainageways located on the
property. If the Governing Body determines that it is in the public interest to alter the
typical required channel section and/or profile of the stream to improve flow, the
Jurisdiction may enter the property within the indicated access or drainage maintenance
and utility easement and carry out the necessary work without liability for any damage to
the property, or improvements thereon, located within the easement.
7) Drainage maintenance and utility easements may be utilized for any underground utility
provided that:
a) Underground utility lines to be installed by any utility provider other than the
Jurisdiction shall be subject to approval by the Enforcement Officer.
b) The government agency, public utility, or private company installing underground
lines after development has been completed by the owner of the property shall be
responsible for the replacement of all fencing, pavement and grassed areas
disturbed by such installation.
c) The Jurisdiction shall not be responsible for damage caused by the installation of
additional lines by any public or private utility company.
d) The Jurisdiction shall not be liable for damages to any improvements located
within the drainage maintenance and utility easement area caused by maintenance
of utilities located therein.
8) No buildings or structures except for water -related improvements shall be placed or
constructed within the access or drainage maintenance and utility easement. All drives,
parking areas, or other improvements, shall be constructed no closer than two (2) feet
horizontally from the top of any back slope along any open watercourse.
(F) Modifications to Drainage or Drainage Maintenance and Utility Easement:
1) This section applies to all recorded drainage or drainage maintenance and utility
easements. This shall include other recorded easements identified by an assortment of
varying names in which one of the principal functions is to convey runoff from
stormwater.
2) Unless strictly prohibited under other applicable sections, easements may be modified,
altered, or relocated with prior approval by the Enforcement Officer based upon review
of certification with supporting technical data by a registered design professional.
Supporting data shall be in accordance with the Guilford County Storm Sewer Design
Manual and must clearly demonstrate that such modifications will not result in any
increase in flood levels or create any adverse impacts during the occurrence of the design
flow discharge. Approval criteria shall include but not be limited to: system capacity to
adequately convey design flow discharge, location of outlet/discharge, resistance to
erosive forces, potential to adversely impact neighboring properties, system maintenance
requirements, existing utilities, other applicable local, state, and federal regulations.
3) Any alteration of a drainage or drainage maintenance and utility easement without prior
approval may be deemed a violation and subject to enforcement actions. Nothing in this
section shall prohibit the installation of utilities as allowed by other sections.

7-1.9. Stream Buffer Required.
(A) Riparian Buffer Protection for Lands within the Jordan Lake Watershed.
1) Authority: Section 7-1.9(A) is adopted pursuant to the authority vested in Guilford County by the
Session Laws and the General Statutes of North Carolina, particularly Session Law 2009-216
(House Bill 239), Session Law 2009-484 (Senate Bill 838), N.C. Gen. Stat §§ 153A-121,
153A-140, Chapter 153A, Article 18, N.C. Gen. Stat §§ 160A-174, 160A-193, Chapter 160A,
Article 19, and any special legislation enacted by the General Assembly for Guilford County.
2) Purpose and Intent: The purposes of the County in adopting Section 7-1.9(A) is to protect and
preserve existing riparian buffers throughout the Jordan Watershed as generally described in
Rule 15A NCAC 02B .0262 (Jordan Water Supply Nutrient Strategy: Purpose and Scope), in
order to maintain their nutrient removal and stream protection functions. Additionally this
Ordinance will help protect the water supply uses of Jordan Reservoir and of designated water
supplies throughout the Jordan Watershed. The requirements of Section 7-1.9(A) shall supersede
all other locally implemented buffer requirements as outlined in Section 7-1.9(B).
Buffers adjacent to streams provide multiple environmental protection and resource management
benefits. Forested buffers enhance and protect the natural ecology of stream systems, as well as
water quality through bank stabilization, shading, and nutrient removal. They also help to
minimize flood damage in flood prone areas. Well -vegetated streamside riparian areas help to
remove nitrogen and prevent sediment and sediment -bound pollutants such as phosphorous from
reaching the streams.
3) Jurisdiction: Section 7-1.9(A) shall be applied to all land in the planning jurisdiction of the
County that is located within the Jordan Reservoir Watershed. The Jordan Reservoir Watershed
includes the Greensboro, Lake Mackintosh, Reidsville, and the non -water supply watersheds as
designated on the Stormwater Map of Guilford County.
4) Applicability: Section 7-1.9(A) applies to all landowners and other persons conducting activities
in the area described in Section 7-1.9(A)3), with the exception of activities conducted under the
authority of the State, the United States, multiple jurisdictions, or local units of government, and
forest harvesting and agricultural activities. The NC Division of Water Quality shall administer
the requirements of Rule 15A NCAC 02B .0267 and .0268 (Jordan Water Supply Nutrient
Strategy: Protection of Existing Riparian Buffers and Mitigation of Existing Riparian Buffers,
respectively) for these activities.
5) Riparian Area Protection within the Jordan Reservoir Watershed:
a. Buffers Protected. The following minimum criteria shall be used for identifying regulated
buffers:

C. Exemption when Existing Uses are Present and Ongoing. This Ordinance shall not apply
to uses that are existing and ongoing; however, this Ordinance shall apply at the time an
existing, ongoing use is changed to another use. Change of use shall involve the initiation
of any activity that does not meet either of the following criteria for existing, ongoing
activity:
It was present within the riparian buffer as of the effective date of this Ordinance
and has continued to exist since that time. Existing uses shall include agriculture,
buildings, industrial facilities, commercial areas, transportation facilities,
maintained lawns, utility lines and on -site sanitary sewage systems, any of which
involve either specific, periodic management of vegetation or displacement of
vegetation by structures or regular activity. Only the portion of the riparian buffer
occupied by the footprint of the existing use is exempt from this Ordinance.
Change of ownership through purchase or inheritance is not a change of use.
Activities necessary to maintain uses are allowed provided that the site remains
similarly vegetated, no impervious surface is added within 50 feet of the surface
water where it did not previously exist as of the effective date of this Ordinance,
and existing diffuse flow is maintained. Grading and revegetating Zone Two is
allowed provided that the health of the vegetation in Zone One is not
compromised, the ground is stabilized and existing diffuse flow is maintained.
ii. Projects or proposed development that are determined by the County to meet at
least one of the following criteria:

Ordinance, or
(4) Projects that are not required to be reviewed by the Clean Water Act
Section 404/National Environmental Policy Act Merger 01 Process
(published by the US Army Corps of Engineers and Federal Highway
Administration, 2003) or its immediate successor if a Finding of No
Significant Impact has been issued for the project and the project has
written approval of the County prior to the effective date of this
Ordinance.
d. Zones of the Riparian Buffer. The protected riparian buffer shall have two zones as
follows:
Zone One shall consist of a vegetated area that is undisturbed except for uses
provided for in the Table of Uses, Section 7-1.9(A)6)b of this Ordinance. The
location of Zone One shall be as follows:
(1) For intermittent and perennial streams, Zone One shall begin at the top of
the bank and extend landward a distance of 30 feet on all sides of the
surface water, measured horizontally on a line perpendicular to a vertical
line marking the top of the bank.
(2) For ponds, lakes and reservoirs located within a natural drainage way,
Zone One shall begin at the normal water level and extend landward a
distance of 30 feet, measured horizontally on a line perpendicular to a
vertical line marking the normal water level.
ii. Zone Two shall consist of a stable, vegetated area that is undisturbed except for
uses provided for in the Table of Uses, Section 7-1.9(A)6)b of this Ordinance.
Grading and revegetating in Zone Two is allowed provided that the health of the

buffer by dispersing concentrated flow prior to its entry into the buffer and reestablishing
vegetation as follows:
Concentrated runoff from new ditches or man-made conveyances shall be
converted to diffuse flow at non -erosive velocities before the runoff enters Zone
Two of the riparian buffer;
ii. Periodic corrective action to restore diffuse flow shall be taken as necessary and
shall be designed to impede the formation of erosion gullies; and
iii. As set out in Sections 7-1.9(A)5)d and 7-1.9(A)6)b of this Ordinance, The Zones
of the Riparian Buffer and Table of Uses respectively, no new stormwater
conveyances are allowed through the buffers except for those specified in the

mitigation shall submit a request for a "no practical alternatives" determination to
the County. The applicant shall certify that the project meets all the following
criteria for finding "no practical alternatives":
(1) The basic project purpose cannot be practically accomplished in a manner
that would better minimize disturbance, preserve aquatic life and habitat,
and protect water quality;
(2) The use cannot practically be reduced in size or density, reconfigured or
redesigned to better minimize disturbance, preserve aquatic life and
habitat, and protect water quality; and
(3) Best management practices shall be used if necessary to minimize
disturbance, preserve aquatic life and habitat, and protect water quality.
ii. The applicant shall also submit at least the following information in support of
their assertion of "no practical alternatives":
(1) The name, address and phone number of the applicant;
(2) The nature of the activity to be conducted by the applicant;
(3) The location of the activity, including the jurisdiction;
(4) A map of sufficient detail to accurately delineate the boundaries of the
land to be utilized in carrying out the activity, the location and dimensions
of any disturbance in riparian buffers associated with the activity, and the
extent of riparian buffers on the land;
(5) An explanation of why this plan for the activity cannot be practically
accomplished, reduced or reconfigured to better minimize disturbance to
the riparian buffer, preserve aquatic life and habitat and protect water
quality; and
(6) Plans for any best management practices proposed to be used to control
the impacts associated with the activity.
Within 60 days of a submission that addresses Section 7-1.9(A)7)a.ii., the County
shall review the entire project and make a finding of fact as to whether the criteria
in Section 7-1.9(A)7)a.i. of this Ordinance have been met. A finding of "no
practical alternatives" shall result in issuance of an Authorization Certificate.
Failure to act within 60 days shall be construed as a finding of "no practical
alternatives" and an Authorization Certificate shall be issued to the applicant
unless one of the following occurs:
(1) The applicant agrees, in writing, to a longer period;
(2) The County determines that the applicant has failed to furnish requested
information necessary to the County decision;
(3) The final decision is to be made pursuant to a public hearing; or
(4) The applicant refuses access to its records or premises for the purpose of
gathering information necessary to the County's decision.
iv. The County may attach conditions to the Authorization Certificate that support
the purpose, spirit and intent of this Ordinance.
V. Any appeals of determinations regarding Authorization Certificates shall be
referred to the Director of the Division of Water Quality, c/o the 401 Oversight
Express Permitting Unit, or its successor. The Director's decision is subject to
review as provided in G.S. 150B Articles 3 and 4.
b. Variances.
Requirements for Variances. Persons who wish to undertake prohibited uses may
pursue a variance. The County may grant minor variances. For major variances,
the County shall prepare preliminary findings and submit them to the Division of
Water Quality, 401 Oversight Express Permitting Unit, or its successor for
approval by the Environmental Management Commission. The variance request
procedure shall be as follows:
(1) For any variance request, the County shall make a finding of fact as to
whether there are practical difficulties or unnecessary hardships that
prevent compliance with the riparian buffer protection requirements. A
finding of practical difficulties or unnecessary hardships shall require that
the following conditions are met:
(I) If the applicant complies with the provisions of this Ordinance,
he/she can secure no reasonable return from, nor make reasonable
use of, his/her property. Merely proving that the variance would
permit a greater profit from the property shall not be considered
adequate justification for a variance. Moreover, the County shall
consider whether the variance is the minimum possible deviation
from the terms of this Ordinance that shall make reasonable use of
the property possible;
(II) The hardship results from application of this Ordinance to the
property rather than from other factors such as deed restrictions or
other hardship;
(III) The hardship is due to the physical nature of the applicant's
property, such as its size, shape, or topography, such that
compliance with provisions of this Ordinance would not allow
reasonable use of the property;
(IV) The applicant did not cause the hardship by knowingly or
unknowingly violating this Ordinance;
(V) The applicant did not purchase the property after the effective date
of this Ordinance, and then request a variance; and
(VI) The hardship is rare or unique to the applicant's property.
(2) The variance is in harmony with the general purpose and intent of the
State's riparian buffer protection requirements and this Ordinance and
preserves its spirit; and
(3) In granting the variance, the public safety and welfare have been assured,
water quality has been protected, and substantial justice has been done.
ii. Minor Variances. A minor variance request pertains to activities that will impact
only Zone Two of the riparian buffer. Minor variance requests shall be reviewed
and approved based on the criteria in Section 7-1.9(A)7)a.i. through Section
7-1.9(A)7)a.iii. by the County pursuant to G.S. 153A-Article 18, or G.S.
160A-Article 19. The County may attach conditions to the variance approval that
support the purpose, spirit and intent of the riparian buffer protection program.
Request for appeals to decisions made by the County shall be made in writing to
the Director of the Division of Water Quality c/o the 401 Oversight Express
Permitting Unit, or its successor. The Director's decision is subject to review as
provided in G.S. 150B Articles 3 and 4.
iii. Major Variances. A major variance request pertains to activities that will impact
any portion of Zone One or any portion of both Zones One and Two of the
riparian buffer. If Guilford County has determined that a major variance request
meets the requirements in Section 7-1.9(A)7)b.i. then it shall prepare a
preliminary finding and submit it to the NC Environmental Management
Commission c/o the Division of Water Quality, 401 Oversight Express Permitting
Unit, or its successor, for approval. Within 90 days after receipt by Guilford
County, the Commission shall review preliminary findings on major variance
requests and take one of the following actions: approve, approve with conditions
and stipulations, or deny the request. Appeals from a Commission decision on a
major variance request are made on judicial review to Superior Court.
C. Mitigation.
This item shall apply to persons who wish to impact a riparian buffer in the
Jordan Watershed when one of the following applies:
(1) A person has received an Authorization Certificate pursuant to Section
7-1.9(A)7)a of this Ordinance for a proposed use that is designated as
"allowable with mitigation;" or
(2) A person has received a variance pursuant to Section 7-1.9(A)7)b of this
Ordinance and is required to perform mitigation as a condition of a
variance approval.
ii. Issuance of the Mitigation Approval. Guilford County shall issue a mitigation
approval upon determining that a proposal meets the requirements set out in this
Ordinance. The approval shall identify at a minimum the option chosen, the
required and proposed areas, and either the mitigation location or the offset
payment amount as applicable.
iii. Options for Meeting the Mitigation Requirement. The mitigation requirement may
be met through one of the following options:
(1) Payment of a compensatory mitigation fee to the Riparian Buffer
Restoration Fund pursuant to 15A NCAC 02B .0269 (Jordan Water
Supply Nutrient Strategy: Riparian Buffer Mitigation Fees to the NC
Ecosystem Enhancement Program) contingent upon acceptance of
payments by the NC Ecosystem Enhancement Program, or to a private
mitigation bank that complies with banking requirements of the US Army
Corps of Engineers, currently set out at
http://www.saw.usace.anny.mil/WETLANDS/Mitigation/mitbanks.html
or from the US Army Corps of Engineers, P.O. Box 1890, Wilmington,
NC, 28402-1890, and the applicable trading criteria in Rule 15A NCAC
02B .0273;
(2) Donation of real property or of an interest in real property pursuant to
Section 7-1.9(A)7)c.vi. of this Ordinance; or
(3) Restoration or enhancement of a non -forested riparian buffer pursuant to
the requirements of Section 7-1.9(A)7)c.vii of this Ordinance.
iv. The Area of Mitigation. Guilford County shall determine the required area of
mitigation, which shall apply to all mitigation options identified in Section
7-1.9(A)7)c.iii. of this Ordinance and as further specified in the requirements for
each option set out in this Section, according to the following:
(1) The impacts in square feet to each zone of the riparian buffer shall be
determined by Guilford County by adding the following:
(I) The area of the footprint of the use causing the impact to the
riparian buffer;
(II) The area of the boundary of any clearing and grading activities
within the riparian buffer necessary to accommodate the use; and
(III) The area of any ongoing maintenance corridors within the riparian
buffer associated with the use.
(2) The required area of mitigation shall be determined by applying the
following multipliers to the impacts determined in Section
7-1.9(A)7)c.iv.(1) of this Ordinance to each zone of the riparian buffer:
(I) Impacts to Zone One of the riparian buffer shall be multiplied by
three;
(II) Impacts to Zone Two of the riparian buffer shall be multiplied by
one and one-half, and
(III) Impacts to wetlands within Zones One and Two of the riparian
buffer that are subject to mitigation under 15A NCAC 2H .0506
shall comply with the mitigation ratios in 15A NCAC 2H .0506.
V. The Location of Mitigation. For any option chosen, the mitigation effort shall be
located within the same subwatershed of the Jordan Watershed, as defined in 15A
NCAC 02B.0262, and the same distance from the Jordan Reservoir as the
proposed impact, or closer to the Reservoir than the impact, and as close to the
location of the impact as feasible. Alternatively, the applicant may propose
mitigation anywhere within the same subwatershed of the Jordan Watershed, as
defined in 15A NCAC 02B.0262, provided that the mitigation proposal accounts
for differences in delivery of nutrients to the affected arm of Jordan Reservoir
resulting from differences between the locations of the buffer impact and
mitigation. Additional location requirements for the property donation option are
enumerated in Section 7-1.9.(A)(7)c.vi.(3)(I) of this Ordinance.
vi. Donation of Property. Persons who choose to satisfy their mitigation
determination by donating real property or an interest in real property shall meet
the following requirements:
(1) The donation of real property interests may be used to either partially or
fully satisfy the payment of a compensatory mitigation fee to the Riparian
Buffer Restoration Fund pursuant to 15A NCAC 02B .0269. The value of
the property interest shall be determined by an appraisal performed in
accordance with Section 7-1.9(A)7)c.vi.(4)(IV) of this Ordinance. The
donation shall satisfy the mitigation determination if the appraised value
of the donated property interest is equal to or greater than the required fee.
If the appraised value of the donated property interest is less than the
required fee calculated pursuant to 15A NCAC 02B .0269, the applicant
shall pay the remaining balance due.
(2) The donation of conservation easements to satisfy compensatory
mitigation requirements shall be accepted only if the conservation
easement is granted in perpetuity.
(3) Donation of real property interests to satisfy the mitigation determination
shall be accepted only if such property meets all of the following
requirements:

Washington, D.C. 20090-6734; and
(V) A title certificate.
vii. Riparian Buffer Restoration or Enhancement. Persons who choose to meet their
mitigation requirement through riparian buffer restoration or enhancement shall
meet the following requirements:
(1) The applicant may restore or enhance a non -forested riparian buffer if
either of the following applies:
(I) The area of riparian buffer restoration is equal to the required area
of mitigation determined pursuant to Section 7-1.9(A)7)c.iv. of this
Ordinance; or
(II) The area of riparian buffer enhancement is three times larger than
the required area of mitigation determined pursuant to Section
7-1.9(A)7)c.iv. of this Ordinance;
(2) The location of the riparian buffer restoration or enhancement shall
comply with the requirements in Section 7-1.9(A)7)c.v. of this Ordinance;
(3) The riparian buffer restoration or enhancement site shall have a minimum
width of 50 feet as measured horizontally on a line perpendicular to the

(4) Enhancement and restoration shall both have the objective of establishing
a forested riparian buffer according to the requirements of this Item.
Enhancement shall be distinguished from restoration based on existing
buffer conditions. Where existing trees are sparse, that is greater than or
equal to 100 trees per acre but less than 200 trees per acre, a buffer may be
enhanced. Where existing woody vegetation is absent, that is less than 100
trees per acre, a buffer may be restored;
(5) The applicant shall first receive an Authorization Certificate for the
proposed use according to the requirements of Section 7-1.9(A)7)a of this
Ordinance. After receiving this determination, the applicant shall submit a
restoration or enhancement plan for approval by the Guilford County. The
restoration or enhancement plan shall contain the following:
(I) A map of the proposed restoration or enhancement site;
(Il) A vegetation plan. The vegetation plan shall include a minimum of
at least two native hardwood tree species planted at a density
sufficient to provide 320 trees per acre at maturity;
(III) A grading plan. The site shall be graded in a manner to ensure
diffuse flow through the riparian buffer;
(IV) A fertilization plan; and
(V) A schedule for implementation;
(6) Within one year after the County has approved the restoration or
enhancement plan, the applicant shall present proof to Guilford County
that the riparian buffer has been restored or enhanced. If proof is not
presented within this timeframe, then the person shall be in violation of
both the State's and the County's riparian buffer protection program;
(7) The mitigation area shall be placed under a perpetual conservation
easement that will provide for protection of the property's nutrient removal
functions, and
(8) The applicant shall submit annual reports for a period of five years after
the restoration or enhancement showing that the trees planted have
survived and that diffuse flow through the riparian buffer has been
maintained. The applicant shall replace trees that do not survive and
restore diffuse flow if needed during that five-year period.
8) Site Inspections and Enforcement.
a. Site Inspections.
Agents, officials, or other qualified persons authorized by the County may
periodically inspect riparian buffers to ensure compliance with this Ordinance.
ii. Notice of the right to inspect shall be included in the letter of approval of each
variance and buffer authorization.
iii. Authorized agents, officials or other qualified persons shall have the authority,
upon presentation of proper credentials, to enter and inspect at reasonable times
any property, public or private, for the purpose of investigating and inspecting the
site of any riparian buffer. No person shall willfully resist, delay, or obstruct an
authorized representative, employee, or agent of Guilford County, while that
person is inspecting or attempting to inspect a riparian buffer nor shall any person
obstruct, hamper or interfere with any such representative while in the process of
carrying out their official duties. The County shall have the power to conduct such
investigations as deemed reasonably necessary to carry out the duties as
prescribed in this Ordinance.
iv. Any person engaged in new activities as defined by this Ordinance who fails to
meet the requirements of this Ordinance shall be deemed in violation of this
Ordinance and subject to enforcement actions under Article 8.
9) Definitions. For the purpose of the Jordan Watershed, these terms shall be defined as follows:
a. "Access Trails" means pedestrian trails constructed of pervious or impervious surfaces
and related structures to access a surface water, including boardwalks, steps, rails, and
signage.
b. "Airport Facilities" means all properties, facilities, buildings, structures, and activities
that satisfy or otherwise fall within the scope of one or more of the definitions or uses of
the words or phrases "air navigation facility", "airport", or "airport protection privileges"
under G.S. 63-1; the definition of "aeronautical facilities" in G.S. 63-79(1); the phrase
"airport facilities" as used in G.S. 159-48(b)(1); the phrase "aeronautical facilities" as
defined in G.S. 159-81 and G.S. 159-97; and the phrase "airport facilities and
improvements" as used in Article V, Section 13, of the North Carolina Constitution,
which shall include, without limitation, any and all of the following: airports, airport
maintenance facilities, clear zones, drainage ditches, fields, hangars, landing lighting,
airport and airport -related offices, parking facilities, related navigational and signal
systems, runways, stormwater outfalls, terminals, terminal shops, and all appurtenant
areas used or suitable for airport buildings or other airport facilities, and all appurtenant
rights -of -way; restricted landing areas; any structures, mechanisms, lights, beacons,
marks, communicating systems, or other instrumentalities or devices used or useful as an
aid, or constituting an advantage or convenience to the safe taking off, navigation, and
landing of aircraft, or the safe and efficient operation or maintenance of an airport or
restricted landing area; easements through, or interests in, air space over land or water,
interests in airport hazards outside the boundaries of airports or restricted landing areas,
and other protection privileges, the acquisition or control of which is necessary to ensure
safe approaches to the landing areas of airports and restricted landing areas, and the safe
and efficient operation thereof and any combination of any or all of such facilities.
Notwithstanding the foregoing, the following shall not be included in the definition of
"airport facilities":
Satellite parking facilities;
ii. Retail and commercial development outside of the terminal area, such as rental
car facilities; and
iii. Other secondary development, such as hotels, industrial facilities, free-standing
offices and other similar buildings, so long as these facilities are not directly
associated with the operation of the airport, and are not operated by a unit of
government or special governmental entity such as an airport authority, in which
case they are included in the definition of 'airport facilities'.
"Channel" means a natural water -carrying trough cut vertically into low areas of the land
surface by erosive action of concentrated flowing water or a ditch or canal excavated for
the flow of water.
d. "DBH" means diameter at breast height of a tree measured at 4.5 feet above ground
surface level.
"Development" means the same as defined in Rule 15A NCAC 2B .0202(23).
f. "Ditch or canal" means a man-made channel other than a modified natural stream
constructed for drainage purposes that is typically dug through inter -stream divide areas.
A ditch or canal may have flows that are perennial, intermittent, or ephemeral and may
exhibit hydrological and biological characteristics similar to perennial or intermittent
streams.
g. "Ephemeral stream" means a feature that carries only stormwater in direct response to
precipitation with water flowing only during and shortly after large precipitation events.
An ephemeral stream may or may not have a well-defined channel, the aquatic bed is
always above the water table, and stormwater runoff is the primary source of water. An
ephemeral stream typically lacks the biological, hydrological, and physical characteristics
commonly associated with the continuous or intermittent conveyance of water.
h. "Existing development" means development, other than that associated with agricultural
or forest management activities, that meets one of the following criteria:
It either is built or has established a vested right based on statutory or common
law as interpreted by the courts, for projects that do not require a state permit, as
of the effective date of either local new development stormwater programs
implemented under Rule 15A NCAC 2B .0265 (Jordan Water Supply Nutrient
Strategy: Stormwater Management for New Development) or, for projects
requiring a state permit, as of the applicable compliance date established in Rule
15A NCAC 2B .0271 (Jordan Water Supply Nutrient Strategy: Stormwater
Management for New Development), Items (5) and (6); or
ii. It occurs after the compliance date set out in Sub -Item (4)(d) of Rule .0265
(Jordan Water Supply Nutrient Strategy: Stormwater Management for New
Development) but does not result in a net increase in built -upon area.
"Greenway/Hiking Trails" means pedestrian trails constructed of pervious or impervious
surfaces and related structures including but not limited to boardwalks, steps, rails, and
signage, and that generally run parallel to the shoreline.
"High Value Tree" means a tree that meets or exceeds the following standards: for pine
species, 14-inch DBH or greater or 18-inch or greater stump diameter; or for hardwoods
and wetland species, 16-inch DBH or greater or 24-inch or greater stump diameter.
k. "Intermittent stream" means a well-defined channel that contains water for only part of
the year, typically during winter and spring when the aquatic bed is below the water
table. The flow may be heavily supplemented by stormwater runoff. An intermittent
stream often lacks the biological and hydrological characteristics commonly associated
with the continuous conveyance of water.
"Jordan nutrient strategy" or 'Jordan water supply nutrient strategy' means the set of
Rules 15A NCAC 2B .0262 through .0273 and .0311(p).
in. "Jordan Reservoir" means the surface water impoundment operated by the US Army
Corps of Engineers and named B. Everett Jordan Reservoir, as further delineated for
purposes of the Jordan nutrient strategy in Rule 15A NCAC 2B .0262(4).
n. "Jordan Watershed" means all lands and waters draining to B. Everett Jordan Reservoir.
o. "New Development" means any development project that does not meet the definition of
existing development set out in this Ordinance.
p. "Perennial stream" means a well-defined channel that contains water year round during a
year of normal rainfall with the aquatic bed located below the water table for most of the
year. Groundwater is the primary source of water for a perennial stream, but it also
carries stormwater runoff. A perennial stream exhibits the typical biological,
hydrological, and physical characteristics commonly associated with the continuous
conveyance of water.
q. "Perennial waterbody" means a natural or man-made basin, including lakes, ponds, and
reservoirs, that stores surface water permanently at depths sufficient to preclude growth
of rooted plants. For the purpose of the State's riparian buffer protection program, the
waterbody must be part of a natural drainage way (i.e., connected by surface flow to a
stream).
"Shoreline stabilization" is the in -place stabilization of an eroding shoreline. Stabilization
techniques which include "soft" methods or natural materials (such as root wads, or rock
vanes) may be considered as part of a restoration design. However, stabilization
techniques that consist primarily of "hard" engineering, such as concrete lined channels,
riprap, or gabions, while providing bank stabilization, shall not be considered stream
restoration.
"Stream restoration" is defined as the process of converting an unstable, altered or
degraded stream corridor, including adjacent riparian zone and flood -prone areas to its
natural or referenced, stable conditions considering recent and future watershed
conditions. This process also includes restoring the geomorphic dimension, pattern, and
profile as well as biological and chemical integrity, including transport of water and
sediment produced by the stream's watershed in order to achieve dynamic equilibrium.
'Referenced' or'referenced reach' means a stable stream that is in dynamic equilibrium
with its valley and contributing watershed. A reference reach can be used to develop
natural channel design criteria for stream restoration projects.
t. "Stream" means a body of concentrated flowing water in a natural low area or natural
channel on the land surface.
U. "Stump diameter" means the diameter of a tree measured at six inches above the ground
surface level.
V. "Surface waters" means all waters of the state as defined in G.S. 143-212 except
underground waters
W. "Tree" means a woody plant with a DBH equal to or exceeding five inches or a stump
diameter exceeding six inches.
X. "Temporary road" means a road constructed temporarily for equipment access to build or
replace hydraulic conveyance structures such as bridges, culverts, pipes or water
dependent structures, or to maintain public traffic during construction.
(B) Riparian Buffer Protection for Lands within the Polecat Creek, Sandy Creek, and Randleman
Lake Watersheds. A stream buffer with a minimum width as specified in Table 7-1-3 measured landward from
the normal pool elevation of impoundments and from the top of bank of each side of streams or rivers, shall be
maintained along all perennial and intermittent streams. This requirement is not applicable to enclosed
subsurface drainage segments of intermittent streams, or to perennial streams outside of water supply
watersheds, in which the North Carolina Division of Water Quality has issued a 401 Water Quality Certification
to allow the stream segment to be altered by routing it through an enclosure such as a culvert. [See Section 7-2.3
(Watershed Critical Area Requirements) for additional requirements concerning stream buffers in the WCA]
No new development is allowed in the buffer except for water dependent structures, other structures such as flag
poles, signs and security lights which result in only diminutive increases in impervious area and public projects
such as road crossings and greenways where no practical alternative exists. These activities shall minimize
built -upon surface area, direct run-off away from the surface waters and maximize the utilization of stormwater
Best Management Practices.

designated as a Water Quality Conservation Easement (WQCE) and the remainder of the stream buffer shall be
a vegetated area. Refer to Article 2, for Water Quality Conservation Easement requirements.
b Under the Low Density Option the stream buffer shall be comprised of Zone 1, which shall be an undisturbed
area of vegetation extending a distance of thirty (30) feet landward from the water line or top of stream bank
along both sides of the stream, and Zone 2, which begins at the outer edge of Zone 1 and extends a minimum of
twenty (20) feet and shall be a vegetated area. Under the High Density Option, the first fifty (50) feet of stream
buffers shall conform to the requirements of Zones 1 and 2, the remainder shall be vegetated. Refer to the
"Water Quality Protection Manual" as amended, for additional stream buffer requirements. Diffuse flow of
runoff shall be maintained in the riparian buffer by dispersing concentrated flow and reestablishing vegetation.
Concentrated runoff from new ditches or man made conveyances shall be converted to diffuse flow before the
runoff enters Zone 2 of the riparian buffer. Periodic corrective action to restore diffuse flow shall be taken if
necessary by the property owner to impede the formation of erosion gullies.
NOTE: All stream buffers shall be identified on a recorded plat as "Drainage and Stream Buffer Easement" or
contained within a Drainageway and Open Space Easement.

Waste minimization and appropriate recycling of materials is encouraged.
3) Properties in the WCA or GWA shall comply with the requirements of the following hazardous
substances regulations if materials listed in the Superfund Amendments and Reauthorization Act
(SARA) Section 302 Extremely Hazardous Substances (42 USC 11000 et seq.), or Section 311

(Amd. of 4-21-05)
7-1.12. Variances.
(A) General:
1) Requests for stormwater management/watershed protection variances shall be submitted in
writing on forms supplied by the governing jurisdiction and with a completed stormwater
management/watershed development plan showing all pertinent information relative to the site in
question. Information shown on the stormwater management/watershed development plan or
presented in writing shall be the primary evidence considered pertinent to the variance request.
2) For each request for a minor or major stormwater management/watershed variance, the
Enforcement Officer shall notify all other local governments having jurisdiction within the same
water supply watershed or using the affected water supply for consumption. A comment period
of at least fourteen (14) days shall be allowed before the Environmental Review Board hearing.
3) In granting variances the jurisdiction may require such conditions as will secure, insofar as
practicable, the objectives of the requirements being modified.
4) The applicant must demonstrate hardship that the regulations impose on the property, not just
apply for a waiver of the rules.
5) The applicant must submit a plan that demonstrates equal or better performance than the current
regulations or conditions.
6) Before the Environmental Review Board or Governing Body may grant a minor watershed
variance or recommend approval to the North Carolina Environmental Management Commission
(EMC) for a major variance , it shall make the following three findings, and shall include the
factual reasons on which they are based.
a) There are practical difficulties or unnecessary hardships in the way of carrying out the
strict letter of the watershed requirements, and all of the following conditions exist:
i) If the applicant complies with the provisions of this rule, the applicant can secure
no reasonable return from, nor make reasonable use of the subject property.
Merely proving that the variance would permit a greater profit from the property
shall not be considered adequate justification for a variance. Moreover, the EMC
or Environmental Review Board shall consider whether the variance is the
minimum possible deviation from the terms of the rule that shall make reasonable
use of property possible.
ii) The hardship results from the application of the rule to the property rather than
from other factors such as deed restrictions or other hardships.
iii) The hardship is due to the physical nature of the applicant's property, such as size,
shape, or topography, which is different from that of neighboring properties.
iv) The applicant did not cause the hardship by knowingly or unknowingly violating
the Rule.
v) The applicant did not purchase the property after the effective date of the Rule,
and then request an appeal to maximize the use of the property. The applicant is
entitled to a variance if a valid hardship is demonstrated.
vi) The hardship is unique to the applicant's property, rather than the result of
conditions that are widespread. If other properties are equally subject to the
hardship created in the restriction, then granting a variance would be a special
privilege denied to others, and would not promote equal justice.
b) The variance is in harmony with the general purpose and intent of the Ordinance and
preserves its spirit.
c) In the granting of the variance the public safety and welfare have been assured, water
quality has been protected, and substantial justice has been done.
(B) Minor Stormwater/Watershed Variances : The Environmental Review Board is designated to
approve minor stormwater management and watershed variances. The Technical Review Committee (TRC)
shall review the submitted request for consistency with the Map Standards in the Guilford County Development
Ordinance prior to forwarding to the Environmental Review Board for approval or denial. Any minor variance
approved by the Environmental Review Board may be appealed to the governing body within fifteen (15) days.
(C) Major Stormwater/Watershed Variances: The North Carolina Environmental Management
Commission (EMC) is designated to approve major stormwater management and watershed variances . The
review process shall be the same as in subsection (B) above, except that the Governing Body shall make
recommendations to the EMC. The variance application, hearing notices, and minutes from each committee and
board review shall be forwarded to the EMC, which shall approve or deny the variance.
(Amd. of 4-21-05; Case No. 5-06, 1-18-07; Case No. lb-08, 3-6-08; Case 5-08, 11-19-09)
7-1.13. Watershed Reporting.
(A) 10/70 Provision -Watershed Reporting: The Enforcement Officer shall keep records on the
County's use of the provisions that a maximum of ten (10) percent of the non -critical area of WS-III watersheds
may be developed with new development at a maximum of seventy (70) percent built -upon surface area.
Records for each watershed shall include the total area of non -critical watershed area, total acres eligible to be
developed under this option, total acres approved for this development option, and individual records for each
project with the following information: location, number of developed acres, type of land use and stormwater
management plan (if applicable).
(B) Stormwater Management/Watershed Variances: The Enforcement Officer shall keep a record of
all stormwater management/watershed variances. This record shall be submitted for each calendar year to the
Division of Water Quality Management on or before January 1 st of the following year and shall provide a
description of each project receiving a minor or major variance and the reasons for granting the variance.

7-4.
SOIL EROSION AND SEDIMENTATION CONTROL
7-4.1. General Requirements.
(A) Plan Required: No person shall initiate any land -disturbing activity without an erosion control
plan approved by the Jurisdiction, if the land -disturbing activity:
1) Exceeds one (1) acre;
2) Will take place on highly erodible soils with a "k" factor greater than .36 in a watershed critical
area;
3) Includes a permanent runoff control structure in a watershed critical area; or
4) Will take place in Tier I or Tier 2 of a watershed critical area.
(B) Protection of Property: Persons conducting land -disturbing activity shall take all reasonable
measures to protect all public and private property from damage caused by such activity.
(C) More Restrictive Rules Shall Apply: Whenever conflicts exist between federal, state, or local
laws, ordinances, or rules, the more restrictive provision shall apply.
7-4.2. Basic Control Objectives.
A soil erosion and sedimentation control plan may be disapproved pursuant to Section 7-4.12(M)
Grounds for Plan Disapproval 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 and/or sedimentation, are to be identified and receive
special attention;
(B) Limit Time of Exposure: All land -disturbing activity is 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;
(E) Control Sedimentation: All land -disturbing activity is to be planned and conducted so as to
prevent off -site sedimentation damage; and
(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, plans are
to include measures to control the velocity at the point of discharge so as to minimize accelerated erosion of the
site and increased sedimentation of the stream.
7-4.3. 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: No land -disturbing activity 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 (25%) percent of the buffer zone nearer
the land -disturbing activity, provided, that this subsection (A) 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. 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 twenty-five (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 steeper than two (2) to
one (1) slope if they are to be stabilized with vegetative cover. Slopes or fills steeper than two (2)
to one (1) slope must be protected by structures. In any event, slopes left exposed will, within
thirty (30) 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
one (1) acre, if more than one (1) acre is 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 7-4.4(B)(5) of this Ordinance, provisions for a
ground cover sufficient to restrain erosion must be accomplished within thirty (30) working days
or one hundred twenty (120) calendar days following completion, whichever period is shorter;
and
(D) Prior Plan Approval: No person shall initiate any land -disturbing activity on a tract if more than
one (1) acre is to be uncovered unless, thirty (30) or more days prior to initiating the activity, an
erosion and sedimentation control plan for such activity is filed with and approved by the
Jurisdiction.
7-4.4. Design and Performance Standards.
(A) Design for Ten-year Storm: Except as provided in Section 7-4.4(B)(2) of this Ordinance, soil
erosion and sedimentation control measures, structures, and devices shall be so planned, designed, and
constructed as 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) High Quality Water Zones: In High Quality Water (HQW) zones the following design standards
shall apply:
1) Uncovered areas in HQW zones shall be limited at any time to a maximum total area within the
boundaries of the tract to twenty (20) acres. Only the portion of the land -disturbing activity
within a HQW zone shall be governed by this subsection. Larger areas may be uncovered within
the boundaries of the tract with the written approval of the Director (DEHNR).
2) Soil 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
twenty -five-year storm which produces the maximum peak rate of runoff as calculated according
to procedures in the United States Department of Agricultural 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) Sediment basins within HQW zones shall be designed and constructed such that the basin will
have a settling efficiency of at least seventy (70) percent for the forty (40) micron 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 Agricultural 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 reorganized organization or association.
4) Newly constructed open channels in HQW zones shall be designed and constructed with side
slopes no steeper than two (2) horizontal to one (1) 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 sufficient to restrain erosion must be provided for any portion of a land -disturbing
activity in a HQW zone within fifteen (15) working days or sixty (60) calendar days following
completion of construction or development, whichever period is shorter.
7-4.5. 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 ten-year storm runoff in the receiving watercourse to the discharge point does
not exceed the greater of:
1) The velocity established by Table 7-4-1; or
2) The velocity of the ten (10) year storm runoff in the receiving watercourse prior to development.
If conditions 1) or 2) above 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 ten (10%) percent.
(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 Jurisdiction
recognizes that the management of stormwater 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 are to:
1) Avoid increases to surface runoff volume and velocity by including measures to promote
infiltration to compensate for increased runoff from areas rendered impervious;
2) Avoid increases in stormwater discharge velocities by using vegetated or roughened swales and
waterways in lieu 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. These may range from simple rip -rapped sections to complex structures; or
4) Protect watercourses subject to accelerated erosion by improving cross sections and/or providing
erosion -resistant lining.
(D) Exceptions: This rule shall not apply where it can be demonstrated that stormwater discharge
velocities will not create an erosion problem in the receiving watercourse.

7-4.6. 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, any waste areas for surplus materials other than landfills regulated by the Department's,
Division of Solid 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
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.
7-4.7. 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.
7-4.8. Operations in Lakes or Natural Watercourses.
Land -disturbing activity in connection with construction in, on, over, or under a lake or natural
watercourse shall be planned and conducted in such a manner as to minimize the 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 characteristic is provided. The U.S. Army Corps of
Engineers shall be notified by the developer of any planned operation in lakes or natural watercourses for
possible issuance of Section 404 or other permits.
7-4.9. 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, by any provision of this Ordinance, or by any ordinance adopted pursuant to this Ordinance. After site
development, the land owner 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.
7-4.10. Additional Measures.
Whenever the Jurisdiction determines that significant 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 shall take additional protective action.
7-4.11. Existing Uncovered Areas.
(A) Applicability: All uncovered areas existing on the effective date of this Ordinance which are the
result of land -disturbing activity, which exceed one (1) acre, which are subject to continued accelerated erosion,
and which are causing off -site damage from sedimentation, shall be provided with a ground cover or other
protective measures, structures, or devices sufficient to restrain accelerated erosion and control off -site
sedimentation.
(B) Notice of Violation: The Jurisdiction will serve upon the landowner a written notice of violation
by registered or certified mail, return receipt requested. The notice will set forth the measures needed to comply
and will state the time within which such measures must be completed. In determining the measures required
and the time allowed for compliance, the authority serving notice shall take into consideration the economic
feasibility, technology, and quantity of work required, and shall set reasonably attainable time limits for
compliance.
(C) Requiring Erosion Control Plan: The Jurisdiction reserves the right to require preparation and
approval of an erosion control plan in any instance where extensive control measures are required.
(D) Exemption: This rule shall not require ground cover on cleared land forming the future basin of a
planned reservoir.
7-4.12. Erosion and Sedimentation Control Plans.
(A) Applicability: An erosion control plan shall be prepared for all land -disturbing activities subject
to this Ordinance whenever the proposed activity is to be undertaken on a tract comprising more than one (1)
acre, if more than one (1) acre is to be uncovered.
(B) Preparation of Plan: The erosion control plan shall be prepared by, and shall bear the seal and
signature of a registered professional engineer, architect, landscape architect, or a registered surveyor to the
extent permitted by North Carolina laws, at a scale not smaller than one (1) inch equals one hundred (100) feet.
The plan shall be filed with the Jurisdiction, and the Guilford Soil and Water Conservation District, thirty (30)
days prior to the commencement of the proposed activity.
(C) Submission of Plan: Persons conducting land -disturbing activity on a tract which covers one (1)
or more acres shall file five (5) copies of the erosion control plan with the Jurisdiction, at least thirty (30) days
prior to beginning of such activity, and shall keep another copy of the plan on file at the job site. If the
Jurisdiction, 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 Jurisdiction will require a revised plan. Pending the
preparation of the revised plan, work shall cease or shall continue under conditions outlined by the appropriate
authority.
(D) Financial Responsibility Statement: Erosion control 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 the person
financially responsible and of the owner of the land or their 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 this compliance or non-compliance with the plan, this Ordinance, or rules or
orders adopted or issued pursuant to this Ordinance.
(E) Conservation District Review: The Guilford Soil and Water Conservation District within twenty
(20) days of receipt of any plan, shall review such plan and submit its comments and recommendations to the
Jurisdiction. Failure of the Soil and Water Conservation District to submit its comments and recommendations
within these twenty (20) days will not delay final action on the plan.
(F) Local Jurisdiction Review: The Jurisdiction will review each plan submitted to them and within
thirty (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 or disapprove a
complete erosion and sedimentation control plan within thirty (30) days of receipt shall be deemed approval.
Denial of a plan must specifically state in writing the reasons for denial. The jurisdiction must approve or deny
a revised plan within fifteen (15) days of receipt, or it is deemed to be approved. If, following commencement
of a land -disturbing activity pursuant to an approved plan, the Jurisdiction determines that the plan is inadequate
to meet the requirements of this Ordinance, the Jurisdiction may require such revisions as are necessary to
comply with this Ordinance.
(G) Plan Requirements: The plan required by this Section shall contain architectural and engineering
drawings, maps, assumptions, calculations, and narrative statements as needed to adequately describe the
proposed development of the tract and the measures proposed to ensure compliance with the requirements of
this Ordinance. Plan content may vary to meet the needs of specific site requirements. Detailed guidelines for
plan preparation can be found in Appendix 2 (Map Standards) of this Ordinance.
(H) Application Amendments: Applications for amendment of an erosion control 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 Jurisdiction, the land -disturbing activity shall not proceed except in
accordance with the erosion control plan as originally approved.
(I) Work Conducted from Approved 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.
(J) Plan Approval Required for Permit: No building or location permits, approvals or other
documents relating to land or building development or improvement shall be issued or granted under applicable
zoning, building, subdivision and other laws and ordinances of the Jurisdiction, unless and until an erosion
control plan, as required by this Ordinance, has been submitted to the Jurisdiction, a grading permit has been
issued, and a Certificate of Erosion Control Performance has been issued by jurisdiction, indicating that initial
erosion control devices have been installed and are functioning properly.
(K) Work Completed Before Final Subdivision Approval: No final subdivision plat approval nor any
Certificate of Occupancy shall be issued or granted where required under applicable zoning, building,
subdivision and other laws and ordinances unless and until work at the site has been completed in accordance
with a valid grading permit, or an improvement security or performance bond has been approved and accepted
as required by this Ordinance.
(L) Surety: The applicant for a grading permit to grade one (1) acre or more may be required to file
with the Jurisdiction an improvement security or bond in the form of an escrow account or other instruments
satisfactory to the Jurisdiction's attorney in the amount deemed sufficient by the Jurisdiction to cover all costs of
protection of the site against erosion and off -site sedimentation according to requirements of this Ordinance.
The amount of such surety requirement shall be determined by the Jurisdiction in consultations with the Soil
and Water Conservation District and with disinterested private contractors. Such surety shall be valid until the
work is completed in accordance with the grading permit and until same is released by the Jurisdiction.
Applicable surety shall be forfeited upon violation of this Ordinance and shall be used to establish protective
cover on the site, to control the velocity of runoff, and/or prevent off -site sedimentation. Any monies in excess
of the cost of providing protective measures shall be refunded to the applicant. Surety shall be released when
the Jurisdiction has certified that the requirements of this Ordinance have been met.
(M) Grounds for Plan Disapproval: A soil erosion and sedimentation control plan may be
disapproved upon a finding that an applicant, or any parent or subsidiary corporation if the applicant is a
corporation:
1) Is conducting or has conducted land -disturbing activity without an approved plan, or has
received notice of violation of a plan previously approved by the Commission or the Jurisdiction
and has not complied with the notice within the time specified in the notice;
2) Has failed to pay a civil penalty assessed pursuant to the Act or this Ordinance which is due and
for which no appeal is pending;
3) Has been convicted of a misdemeanor pursuant to NCGS 113A-64(b) or any criminal provision
of this Ordinance; and
4) Has failed to substantially comply with State rules adopted pursuant to the Act or regulations of
this Ordinance.
For purposes of this subsection an applicant's record may be considered for only the two (2) years prior
to the application date.
(N) North Carolina Environmental Policy Act: Any plan submitted for a land -disturbing activity for
which an environmental document is required by the North Carolina Environmental Policy Act (NCGS I I3A-1,
et seq.) shall be deemed incomplete until a complete environmental document is available for review. Guilford
County shall promptly notify the person submitting the plan that the thirty (30) day time limit for review of the
plan pursuant to Section 7-4.12(F) of this Ordinance shall not begin until a complete environmental document is
available for review.

FLOOD DAMAGE PREVENTION*
* Editors Note: An amendment adopted May 17, 2007, amended 7-5 in its entirety to read as herein set out. Former 7-5, §§
7-5.1--7-5.7, pertained to similar subject matter, and derived from development ordinance adopted January 1, 1992; Amd. of 4-21-05;
Case No. 5-06, 1-8-07.
7-5.1. Statutory Authorization and Legal Status Provisions.
(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 Part 121, Article 6 of Chapter 153A of the
North Carolina General Statutes, delegated to local governmental units the responsibility to adopt regulations
designed to promote the public health, safety, and general welfare of its citizenry.
(B) Legal Status Provisions:
(1) Effect on Rights and Liabilities under the Existing Flood Damage Prevention Ordinance: This
Ordinance in part comes forward by re-enactment of some of the provisions of the Flood
Damage Prevention Ordinance enacted on November 19, 1990, as amended, and it is not the
intention to repeal but rather to re-enact and continue to enforce without interruption of such
existing provisions, so that all rights and liabilities that have accrued thereunder are reserved and
may be enforced. The enactment of this Ordinance shall not affect any action, suit or proceeding
instituted or pending. All provisions of the Flood Damage Prevention Ordinance of the
unincorporated areas of Guilford County enacted on November 19, 1990, as amended, which are
not reenacted herein are repealed.
(2) Effect upon Outstanding Floodplain Development Permits: Nothing herein contained shall
require any change in the plans, construction, size, or designated use of any development or any
part thereof for which a Floodplain Development Permit has been granted by the Floodplain
Administrator or his or her authorized agents before the time of passage of this Ordinance;
provided, however, that when construction is not begun under such outstanding permit within a
period of six (6) months subsequent to the date of issuance of the outstanding permit,
construction or use shall be in conformity with the provisions of this Ordinance.
(3) Effective Date: This Ordinance shall become effective upon adoption.
(Amd. of 5-17-07)
7-5.2. Findings of Fact.
(A) The flood prone areas within the jurisdiction of unincorporated Guilford 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 prone areas of uses vulnerable to floods
or other hazards.
(Amd. of 5-17-07)
7-5.3. General Provisions.
GRAPHIC UNAVAILABLE: Click here
(A) Lands to Which this Ordinance Applies: This Ordinance shall apply to all Special Flood Hazard
Areas within unincorporated Guilford County. Bona fide farms are not exempt from the provisions of this
Ordinance regulating development in floodways and floodplains as required for participation in the National
Flood Insurance Program.
(B) Basis for Establishing the Special Flood Hazard Areas: The Special Flood Hazard Areas are
those identified under the Cooperating Technical State (CTS) agreement between the State of North Carolina
and FEMA in its Flood Insurance Study (FIS) and its accompanying Flood Insurance Rate Maps (FIRM), for
Guilford County, dated June 18, 2007 which are adopted by reference and declared to be a part of this
Ordinance.
(Amd. of 5-17-07)
7-5.4. Establishment of Floodplain Development Permit.
A Floodplain Development Permit shall be required in conformance with the provisions of this
Ordinance prior to the commencement of any development activities within Special Flood Hazard Areas
determined in accordance with Section 7-5.3(B) of this Ordinance.
(Amd. of 5-17-07)
7-5.5. Compliance.
No structure or land shall hereafter be located, extended, converted, altered, or developed in any way
without full compliance with the terms of this Ordinance and other applicable regulations.
(Amd. of 5-17-07)
7-5.6. Warning and Disclaimer of Liability.
The degree of flood protection required by this Ordinance is considered reasonable for regulatory
purposes and is based on scientific and engineering consideration. Larger floods can and will occur. Actual
flood heights may be increased by man-made or natural causes. This Ordinance does not imply that land outside
the Special Flood Hazard Areas or uses permitted within such areas will be free from flooding or flood
damages. This Ordinance shall not create liability on the part of Guilford County or by any officer or employee
thereof for any flood damages that result from reliance on this Ordinance or any administrative decision
lawfully made hereunder.
(Amd. of 5-17-07)
7-5.7. Floodplain Development Application, Permit and Certification Requirements.

non -encroachment area, or stream setback, and provided that such repair, reconstruction, or
replacement meets all of the other requirements of this Ordinance.
10) New solid waste disposal facilities and sites, hazardous waste management facilities, salvage
yards, and chemical storage facilities shall not be permitted, except by variance as specified in
Section 9-5.9 (J). A structure or tank for chemical or fuel storage incidental to an allowed use or
to the operation of a water treatment plant or wastewater treatment facility may be located in a
Special Flood Hazard Area only if the structure or tank is either elevated or floodproofed to at
least the Regulatory Flood Protection Elevation and certified according to Section 3-8.4 of this
Ordinance.
11) All subdivision proposals and other development proposals shall be consistent with the need to
minimize flood damage.
12) All subdivision proposals and other development proposals shall have public utilities and
facilities such as sewer, gas, electrical, and water systems located and constructed to minimize
flood damage.
13) All subdivision proposals and other development proposals shall have adequate drainage
provided to reduce exposure to flood hazards.
14) All subdivision proposals and other development proposals shall have received all necessary
permits from those governmental agencies for which approval is required by Federal or State
law, including Section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33

on which a structure is to be located shall be extended at grade ten (10) feet beyond the
limits of the structure foundation, and shall have a side slope no steeper than two (2) feet
horizontal to one (1) foot vertical.
(B) Specific Standards: In all Special Flood Hazard Areas where Base Flood Elevation (BFE) data
has been provided, as set forth in Section 7-5.3(B), or Section 9-7.3 (11 & 12), the following provisions, in
addition to Section 7-5.8(A), are required:
1) Residential Construction. New construction and substantial improvement of any residential
structure (including manufactured homes) shall have the reference level, including basement,
elevated no lower than the Regulatory Flood Protection Elevation, as defined in Section 2-1.6 of
this Ordinance.
2) Non -Residential Construction. New construction and substantial improvement of any
commercial, industrial, or other non-residential structure shall have the reference level, including
basement, elevated no lower than the Regulatory Flood Protection Elevation, as defined in
Section 2-1.6 of this Ordinance. Structures located in A, AE and Al-30 Zones may be
floodproofed to the Regulatory Flood Protection Elevation in lieu of elevation provided that all
areas of the structure, together with attendant utility and sanitary facilities, below the Regulatory
Flood Protection 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 registered professional engineer or architect
shall certify that the standards of this subsection are satisfied. Such certification shall be
provided to the Floodplain Administrator as set forth in Section 3-8.4, along with the operational
and maintenance plans.
3) Manufactured Homes.
a) New or replacement manufactured homes shall be elevated so that the reference level of
the manufactured home is no lower than the Regulatory Flood Protection Elevation, as
defined in Section 2-1.6 of this Ordinance.
b) Manufactured homes shall be securely anchored to an adequately anchored foundation to
resist flotation, collapse, and lateral movement, either by engineer certification, or in
accordance with the most current edition of the State of North Carolina Regulations for
Manufactured Homes adopted by the Commissioner of Insurance pursuant to NCGS
143-143.15. Additionally, when the elevation would be met by an elevation of the chassis
thirty-six (36) inches or less above the grade at the site, the chassis shall be supported by
reinforced piers or engineered foundation. When the elevation of the chassis is above
thirty-six (36) inches in height, an engineering certification is required.
c) All enclosures or skirting below the lowest floor shall meet the requirements of Section
7-5.8 (13)(4)(a), (b), and (c).
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 Floodplain Administrator and the local Emergency Management coordinator.
4) Elevated Buildings. Fully enclosed area, of new construction and substantially improved
structures, which is below the lowest floor:
a) Shall not be designed or used for human habitation, but shall only be used for parking of
vehicles, building access, or limited storage of maintenance equipment used in
connection with the premises. Access to the enclosed area shall be the minimum
necessary to allow for parking of vehicles (garage door) or limited storage of
maintenance equipment (standard exterior door), or entry to the living area (stairway or
elevator). The interior portion of such enclosed area shall not be finished or partitioned
into separate rooms, except to enclose storage areas;
b) Shall be constructed entirely of flood resistant materials to the top of any enclosure below
the lowest floor;
c) Shall include, in Zones A, AE, and Al-30, flood openings to automatically equalize
hydrostatic flood forces on walls by allowing for the entry and exit of floodwaters. To
meet this requirement, the openings must either be certified by a professional engineer or
architect or meet or exceed the following minimum design criteria;
i) A minimum of two (2) flood openings on different sides of each enclosed area
subject to flooding;
ii) The total net area of all flood openings must be at least one (1) square inch for
each square foot of enclosed area subject to flooding;
iii) If a building has more than one (1) enclosed area, each enclosed area must have
flood openings to allow floodwaters to automatically enter and exit;
iv) The bottom of all required flood openings shall be no higher than one (1) foot
above the adjacent grade;
v) Flood openings may be equipped with screens, louvers, or other coverings or
devices, provided they permit the automatic flow of floodwaters in both
directions; and
vi) Enclosures made of flexible skirting are not considered enclosures for regulatory
purposes, and, therefore, do not require flood openings. Masonry or wood
underpinning, regardless of structural status, is considered an enclosure and
requires flood openings as outlined above.
5) AdditionsAmprovements.
a) Additions and/or improvements to pre -FIRM structures when the addition and/or
improvements in combination with any interior modifications to the existing structure
are:
i) Not a substantial improvement, the addition and/or improvements must be
designed to minimize flood damages and must not be any more non -conforming
than the existing structure.
ii) A substantial improvement, both the existing structure and the addition and/or
improvements must comply with the standards for new construction.
b) Additions to post -FIRM structures with no modifications to the existing structure other
than a standard door in the common wall shall require only the addition to comply with
the standards for new construction.
c) Additions and/or improvements to post -FIRM structures when the addition and/or
improvements in combination with any interior modifications to the existing structure
are:
i) Not a substantial improvement, the addition and/or improvements only must
comply with the standards for new construction.
ii) A substantial improvement, both the existing structure and the addition and/or
improvements must comply with the standards for new construction.
d) Where an independent perimeter load -bearing wall is provided between the addition and
the existing building, the addition(s) shall be considered a separate building and only the
addition must comply with the standards for new construction.
6) Recreational Vehicles. Recreational vehicles shall either:
a) Be on site for fewer than one hundred eighty (180) consecutive days and be fully licensed
and ready for highway use (a recreational vehicle is ready for highway use if it is on its
wheels or jacking system, is attached to the site only by quick disconnect type utilities,
and has no permanently attached additions); or
b) Meet all the requirements for new construction.
7) Temporary Non -Residential Structures. Prior to the issuance of a Floodplain Development
Permit for a temporary structure, the applicant must submit to the Floodplain Administrator a
plan for the removal of such structure(s) in the event of a hurricane, flash flood or other type of
flood warning notification. The following information shall be submitted in writing to the
Floodplain Administrator for review and written approval;
a) A specified time period for which the temporary use will be permitted. Time specified
may not exceed three months, renewable up to one year;
b) The name, address, and phone number of the individual responsible for the removal of
the temporary structure;
c) 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);
d) A copy of the contract or other suitable instrument with the entity responsible for
physical removal of the structure; and
e) Designation, accompanied by documentation, of a location outside the Special Flood
Hazard Area, to which the temporary structure will be moved.
8) Accessory Structures. When accessory structures (sheds, detached garages, etc.) are to be placed
within a Special Flood Hazard Area, the following criteria shall be met:
a) Accessory structures shall not be used for human habitation (including working, sleeping,
living, cooking or restroom areas);
b) Accessory structures shall not be temperature -controlled;
c) Accessory structures shall be designed to have low flood damage potential;
d) Accessory structures shall be constructed and placed on the building site so as to offer the

e) Accessory structures shall be firmly anchored in accordance with Section 7-5.8(A)(1);
f) All service facilities such as electrical shall be installed in accordance with Section
7-5.8(A)(4); and
g) Flood openings to facilitate automatic equalization of hydrostatic flood forces shall be
provided below Regulatory Flood Protection Elevation in conformance with Section
7-5.8(B)(4)(c).
An accessory structure with a footprint less than one hundred fifty (150) square feet that satisfies
the criteria outlined above does not require an elevation or floodproofing certificate. Elevation or
floodproofing certifications are required for all other accessory structures in accordance with
Section 3-8.4.
(Amd. of 5-17-07)
7-5.9. Standards for Floodplains without Established Base Flood Elevations.
(A) Within the Special Flood Hazard Areas designated as Approximate Zone A and established in
Section 7-5.3(B), where no Base Flood Elevation (BFE) data has been provided by FEMA, the following
provisions, in addition to Section 7-5.8(A) and (B), shall apply:
No encroachments, including fill, new construction, substantial improvements or new development shall be
permitted within a distance of twenty (20) feet each side from top of bank or five (5) times the width of the
stream, whichever is greater, 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.
(B) The BFE used in determining the Regulatory Flood Protection Elevation shall be determined
based on one of the following criteria set in priority order:
1) If Base Flood Elevation (BFE) data is available from other sources, all new construction and
substantial improvements within such areas shall also comply with all applicable provisions of
this Ordinance and shall be elevated or floodproofed in accordance with standards in Section
9-7.3 (11 & 12).
2) All subdivision, manufactured home park and other development proposals shall provide Base
Flood Elevation (BFE) data if development is greater than five (5) acres or has more than fifty
(50) lots/manufactured home sites. Such Base Flood Elevation (BFE) data shall be adopted by
reference per Section 7-5.3(B) to be utilized in implementing this Ordinance.
3) When Base Flood Elevation (BFE) data is not available from a Federal, State, or other source as
outlined above, the reference level shall be elevated to or above the Regulatory Flood Protection
Elevation, as defined in Section 2-1.6.
(Amd. of 5-17-07)
7-5.10. Standards for Riverine Floodplains with BFE but Without Established Floodways or
Non -Encroachment Areas.
Along rivers and streams where BFE data is provided but neither floodway nor non -encroachment areas
are identified for a Special Flood Hazard Area on the FIRM or in the FIS report, the following requirements
shall apply to all development within such areas:
(A) Standards outlined in Sections 7-5.8(A) and (B); and
(B) Until a regulatory floodway or non -encroachment area is designated, no encroachments,
including fill, new construction, substantial improvements, or other development, shall be
permitted unless certification with supporting technical data by a registered professional engineer
is provided demonstrating that the cumulative effect of the proposed development, when
combined with all other existing and anticipated development, will not increase the water surface
elevation of the base flood more than one foot at any point within the community.

7-5.11. Floodways and Non -Encroachment Areas.
Areas designated as floodways or non -encroachment areas are located within the Special Flood Hazard
Areas established in Section 7-5.3(B). The floodways and non -encroachment areas are extremely hazardous
areas due to the velocity of floodwaters that have erosion potential and carry debris and potential projectiles.
The following provisions, in addition to standards outlined in Sections 7-5.8(A) and (B), shall apply to all
development within such areas:
(A) No encroachments, including fill, new construction, substantial improvements and other
developments shall be permitted unless it has been demonstrated that:
1) The proposed encroachment would not result in any increase in the flood levels during
the occurrence of the base flood, based on hydrologic and hydraulic analyses performed
in accordance with standard engineering practice and presented to the Floodplain
Administrator prior to issuance of Floodplain Development Permit, or
2) A Conditional Letter of Map Revision (CLOMR) has been approved by FEMA. A Letter
of Map Revision (LOMR) must also be obtained upon completion of the proposed
encroachment.
(B) If Section 7-5.11(A) is satisfied, all development shall comply with all applicable flood hazard
reduction provisions of this Ordinance.
(C) No manufactured homes shall be permitted, except replacement manufactured homes in an
existing manufactured home park or subdivision, provided the following provisions are met:
1) The anchoring and the elevation standards of Section 7-5.8(B)(3); and
2) The no encroachment standard of Section 7-5.11(A).
(D) Permitted Uses: The following uses shall be permitted within the floodway zone to the extent
that they are otherwise permitted by this Ordinance and provided that they do not employ
structures or fill except as specified herein:
1) General farming, pasture, outdoor plant nurseries, horticulture, forestry, wildlife
sanctuary, game farm, and other similar agricultural, quarrying, wildlife and related uses;
2) Ground level loading areas, ground level automobile parking areas, rotary aircraft ports
and other similar industrial and commercial uses;
3) Tractor -trailer parking, provided that no trailers shall be detached from tractors;
4) Lawns, gardens, play areas, and other similar uses;
5) Golf courses, tennis courts, driving ranges, archery ranges, picnic grounds, parks,
swimming pools, hiking or horseback riding trails, open space and other similar private
and public recreational uses;
6) Streets, bridges, utility lines, storm drainage facilities, sewage or waste treatment
facilities, water supply facilities, and other similar public or private utility uses, but only
if the proposed activity combined with the allowable encroachment of the floodway
fringe and with any previously placed or previously approved encroachment in the
complies with the provisions of Section 7-5.11(A);
7) Temporary facilities such as displays, circuses, carnivals, or similar transient amusement
enterprises;
8) Boat docks, ramps, piers, or similar structures;
9) Grading, as it complies with the provisions of Section 7-5.11(A); and
10) Cantilevered portions of structures, provided that foundation and supports are located
outside the floodway zone and the underside of the cantilevered portion is at least two (2)
feet above Base Flood Elevation.
(E) Prohibited Uses: Storage or processing of materials that are flammable, corrosive, toxic, or
explosive, or which could otherwise be injurious to human, animal or plant life in time of flood
is prohibited in the floodway zone.
