IV. WATERSHED / STORMWATER
PERMIT PROCESS
A. Purpose and Application
The purpose of the Watershed and Stormwater
Permit Process is to provide a mechanism for the
review, approval, and inspection of the approach
to be used for the management and control of
Stormwater for a development or redevelopment
site consistent with the requirements of the
Town of Kernersville's UDO, whether the
approach consists of structural BMPs or other
techniques such as low -impact or low -density
design. Compliance after project construction is
Watershed and Stormwater Administrative Manual 2 Revised 2020-02-01
assured by the maintenance provisions of the
Town of Kernersville Stormwater and
Watershed Ordinances.
A Watershed/Stormwater Permit is required for
all development and redevelopment unless
exempt pursuant to the Town of Kernersville
Stormwater and Watershed Ordinances. No
building or built -upon area shall be erected or
expanded, nor shall any building or zoning
permit be issued until a Watershed/Stormwater
Permit has been issued by the Watershed
Administrator or Town Manager's designee.
A properly submitted packet (plans, calculation,
legal documents, etc.), as well as a reviewed and
approved Watershed/Stormwater Permit
Application, are required for the issuance of a
Watershed/Stormwater Permit. All plans
submitted with the application shall be prepared
by a registered North Carolina professional
engineer or landscape architect. The engineer or
landscape architect shall perform services only
in their area of competence and shall verify that
the design of all stormwater management
facilities and practices meets the submittal
requirements for complete applications; that the
designs and plans are sufficient to comply with
applicable standards and policies found in the
North Carolina Stormwater Best Management
Practices Manual, and the North Carolina
Department of Transportation Stormwater Best
Management Practices Toolbox if it is a linear
transportation project; and that the designs and
plans ensure compliance with the Town of
Kernersville Stormwater and Watershed
Ordinances.
B. Watershed/Stormwater Permitting
Process
1. Planning, Preliminary Design, and
Concept Plan
Before plans will be reviewed and approved
for construction, preliminary site plans must
be reviewed by the Watershed Administrator
through the Community Development
department review process.
Based upon the review of existing
conditions and site analysis, the designer
should develop a concept site layout plan for
the project. During the concept plan stage
the site designer will perform most of the
layout of the site including the preliminary
stormwater management system design and
layout. The stormwater concept plan allows
the design engineer to propose a potential
site layout and gives the developer and local
review staff preliminary information
regarding the stormwater management
system for the proposed development.
The following steps should be followed in
developing the stormwater concept plan:
a. Use appropriate site design approaches
(see the North Carolina Stormwater Best
Management Practices Manual) as
applicable to develop the site layout,
including:
• Preserving the natural feature
conservation areas defined in the
site analysis.
• Fitting the development to the
terrain and minimizing land
disturbance.
• Reducing impervious surface area
through various techniques.
• Preserving and utilizing the natural
drainage system wherever possible.
b. Calculate preliminary estimates of the
The Watershed/Stormwater Permitting Process
stormwater sizing criteria requirements
can be separated into three phases of stages:
for water quality, channel protection,
Planning, Preliminary Design, and Concept
overbank flooding protection and
Plan; Final Stormwater Management Plan,

and Construction and Construction Inspections
of Stormwater Control Structures-BMP(s).
c. Perform screening and preliminary
selection of appropriate structural
Watershed and Stormwater Administrative Manual 3 Revised 2020-02-01
stormwater controls and identification of
potential sitting locations.
It is extremely important at this stage
that stormwater design is integrated into
the overall site design concept in order
to best reduce the impacts of the
development as well as provide for the
most cost-effective and environmentally
sensitive approach. The goal of
maintaining natural hydrologic
conditions as a site is developed, to the
extent possible, can reduce the
economic costs of stormwater
management and minimize the negative
environmental impacts associated with
development.
It is recommended that prior to the
preparation of the Final Stormwater
Plan; the owner or developer shall
request a consultation meeting with the
Watershed Administrator on a concept
plan for the post -construction
stormwater management system to be
utilized in the proposed development
project. This consultation meeting shall
take place at the time of the preliminary
plan of subdivision or other early step in
the development process. The purpose
of this meeting is to discuss the post -
construction stormwater management
measures necessary for the proposed
project, as well as to discuss and assess
constraints, opportunities and potential
approaches to stormwater management
designs before formal site design
engineering is commenced. The
development process will typically
proceed much faster and smoother if the
concept meeting is conducted very early
in the process.
Appendix 01 "Stormwater Concept Plan
- Preliminary Site Plan Requirements
Submittal Checklist" contains the list of
the items that should be submitted to the
Watershed Administrator for review
purposes prior to the preparation and
submittal of the Final Stormwater
Management Plan and Construction
Plans.
The Stormwater Management System
Concept Plan is only a portion of the
preliminary submittal through the
Community Development Department
review process. The Community
Development Department must approve
the proposed preliminary site plan with
respect to City ordinances and policies
relating to all components of the
development plan (e.g., zoning,
subdivision, utility, landscape, etc.) in
addition to the Stormwater Management
System Concept Plan before the
developer may submit an application
and construction plans for the
Watershed/Stormwater Permit.
The "Planning, Preliminary Design, and
Concept Plan" phase is outlined in
Appendix 02 "Stormwater Management
System Concept Plan Review Submittal
Process"
2. Final Stormwater Management Plan,
Construction Drawing Review, and
Permitting
The final Stormwater Management Plan
ensures that requirements and criteria are
being complied with and that opportunities
are being taken to minimize adverse impacts
from the development. The Final
Stormwater Management Plan should
consist of plans; narrative and supporting
design calculations (hydrologic and
hydraulic); proper documentation and
adequate financial assurance for the
proposed stormwater management system.
For review purposes, the final stormwater
management plan should include the
following elements:
a. Existing Conditions Hydrologic

Once the Watershed/Stormwater Permit is
issued, construction may begin, provided all
other environmental permits have been
obtained, or are in the process of being
obtained, and all requirements of the Town
of Kernersville Community Development
Department have been satisfied. During
construction, Town staff may conduct
periodic construction inspections of
Stormwater BMP(s), however the designer
is ultimately responsible to certify that any
structural BMPs meet the requirements of
the ordinance and Stormwater Permit.
Certain BMP(s) (as Bio-retention Areas)
should not be constructed until the drainage
area to that BMP has been stabilized.
Should a BMP be constructed prior to
adequate ground stabilization provisions
being implemented, the responsibility of
reconstruction, replanting or replacement of
any contaminated soils is the responsibility
of the owner
Upon completion of a project, and before a
certificate of occupancy shall be granted, the
applicant shall certify that the completed
project is in accordance with the approved
Stormwater Management Plan and design,
and shall submit "as built" plans for all
BMPs after final construction is completed
to the Watershed Administrator. The plans
shall show the final design specifications for
all stormwater management facilities and
practices and the field location, size, depth,
and planted vegetation of all measures,
controls, and devices, as installed.
The designer of the stormwater management
measures and plans shall also certify, under
seal, that the as -built stormwater measures,
controls, and devices are in compliance with
the approved stormwater plans and designs
and with the requirements of the Town of
Kemersville's applicable ordinances.
Appendix 14 "Engineer's Certificate of

requirements; the owner may request
release of fifty percent (50%) of the
performance surety. Upon request by the
owner, the Stormwater Division shall
inspect the stormwater control structure(s) to
determine that the stormwater control(s)
have been constructed and maintained as
required by the Town of Kemersville's
Stormwater and Watershed Ordinances.
Watershed and Stormwater Administrative Manual 8 Revised 2020-02-01
The Stormwater Administrator, upon
determining that the stormwater control(s)
have been installed in conformity with the
Town of Kernersville's Stormwater and
Watershed Ordinances and maintained
properly, shall release fifty percent (50%) of
the performance surety.
No sooner than one year after the
completion of the Stormwater control
structure, BMP(s), the owner may request
release of the remainder of the performance
surety. Upon request by the owner, the
Stormwater Division shall inspect the
stormwater control structure(s) to determine
that the stormwater control(s) are
performing as required by the Town of
Kemersville's Stormwater and Watershed
Ordinances.
If the plantings or other features cannot be
viewed due to time of year, plant dormancy
or leaf cover, then the inspection may be
delayed until such time as the inspection
may be performed.
The Stormwater Administrator, upon
determining that the stormwater control(s)
are performing as required by the Town of
Kemersville's Stormwater and Watershed
Ordinances, and after any needed repairs to
the stormwater control structure(s) are made
by the owner, shall release the remaining
performance surety.
Upon default of the owner to construct,
maintain, repair and, if necessary,
reconstruct any structural BMP in
accordance with the applicable permit or
operation and maintenance agreement, the
Town of Kernersville may use all or any
portion of the performance surety to make
necessary improvements based on an
engineering estimate or bids.
Such expenditure of funds shall only be
made after requesting the owner to comply
with the permit or maintenance agreement.
In the event of a default triggering the use of
installation performance surety, the Town of
Kernersville shall not return any of the
unused performance surety, which shall be
retained for maintenance. If the Town of
Kernersville takes action upon such failure
by the applicant or owner, the Town of
Kernersville may collect from the applicant
or owner for the difference should the
amount of the reasonable cost of such action
exceed the amount of the performance
surety held.

HOMEOWNERS (or other) ASSOCIATION OPERATION AND MAINTENANCE AGREEMENT
THIS AGREEMENT made pursuant to Town of Kemersville Watershed Protection and Stormwater
Ordinances and entered into this day of , 20_, by and between the TOWN OF KERNERSVILLE,
a North Carolina Municipal Corporation, Party of the First Part, hereinafter referred to as "TOWN'; and
here -in after referred to as "DEVELOPER", and here -in after referred to as the "ASSOCIATION",
Parties of the Second Part.
WITNESSETH:
1. The TOWN under various state and federal laws, is required to regulate the maintenance of
engineered Stormwater Control Measures and related structures (hereinafter referred to as "SCMs") constructed to
serve new or re -development within both the corporate limits of the TOWN and within the extra territorial zoning
jurisdiction of the TOWN to ensure that, following initial construction, the SCMs are operated, maintained, and to
the extent necessary, repaired in accordance with applicable state and federal laws.
2. The TOWN has determined that, to maintain the Town's compliance under applicable state and
federal regulations, certain obligations are to be met by the DEVELOPER and subsequent owners of the SCMs.
3. The DEVELOPER is the owner of certain lands as described in Deed Book , Page
in the Office of the Register of Deeds of Forsyth County, North Carolina upon which it is erecting and will
make improvements, said development to be known as
(hereinafter referred to as the "PROPERTY').
4. The DEVELOPER desires to build SCMs to provide storage and treatment of stormwater runoff to
serve the development on said PROPERTY, as required by the Kernersville Watershed Protection and Stormwater
Ordinances (hereinafter referred to as "ORDINANCES").
5. The DEVELOPER has applied to the TOWN for the issuance of a high density watershed/stormwater
permit (hereinafter referred to as "PERMIT") to construct, maintain and operate the SCMs consistent with the
approved plans and specifications on file at the office of the Watershed Administrator and the Operation and
Maintenance Plan (ATTACHMENT A).
6. The DEVELOPER has conveyed unto the TOWN, or its successors or assigns, an Easement and
Right -of -Way establishing the right of ingress, egress and regress over the PROPERTY for the purpose of inspection,
repair, or maintenance of the SCMs. The Easement and Right -of -Way for the SCMs are described in Deed Book ,
Page , which is recorded in the Office of the Register of Deeds of Forsyth (or Guilford, if applicable) County,
North Carolina.
7. The TOWN desires to assure that the SCMs on the PROPERTY are properly constructed,
maintained and operated in accordance with law, the ORDINANCES, and PERMIT provisions in order to protect the
quality of the waters of the State and the public interest therein.
Watershed and Stormwater Administrative Manual 38 Revised 2020-02-01
8. These SCMs are required to comply with the ORDINANCES and that failure to maintain the SCMs
is a violation of the ORDINANCES potentially subjecting each lot owner of the PROPERTY to significant daily civil
penalties and other enforcement actions.
9. After the completion of construction of the SCMs, the DEVELOPER may convey the SCMs to the
ASSOCIATION.
NOW, THEREFORE, in consideration of the promises and the benefits to be derived by each of the parties
hereto, the TOWN, the DEVELOPER and the ASSOCIATION do hereby mutually agree as follows:
l . The DEVELOPER shall construct the SCMs in accordance with the ORDINANCES, PERMIT and
plans and specifications hereafter issued and approved by the TOWN; and that DEVELOPER and ASSOCIATION
assume specific maintenance, replacement, reconstruction and repair, responsibilities set forth in the ORDINANCES
and with respect to the SCMs.
2. Construction and Maintenance of the SCMs: The DEVELOPER shall be responsible for the
construction of the SCMs; and prior to conveying control of the SCMs, the DEVELOPER will be responsible for
maintenance, repair, reconstruction, and replacement thereof. Following conveyance of the SCMs, the
ASSOCIATION and its members will be responsible for maintaining the SCMs, their appurtenances and vegetation
in the manner specified herein and in strict compliance with the ORDINANCES. At all times, the SCMs shall perform
as designed and shall at all times comply with all applicable laws, ordinances, regulations, rules and directives of
governmental authorities.
3. Ownership and/or Transfer of PROPERTY: Upon completion of the SCMs, the DEVELOPER has
the option to convey that portion of the PROPERTY on which the SCMs are located to an Association to be formed
for the purpose of administrating the provisions of a declaration of covenants to be imposed upon the PROPERTY,
which declaration shall fully comply with all requirements of this contract as well as all applicable laws. The
Declaration of Covenants, Conditions and Restrictions for PROPERTY, in reference to this contract and all applicable
stormwater and watershed laws, shall be subject to review and approval by the Town of Kemersville Attorney.
The DEVELOPER agrees that it shall not transfer ownership and/or control of the SCMs until construction has been
completed in accordance with the PERMIT and approved plans and specifications; and as defined in the
ORDINANCES, the TOWN has inspected and approved the SCMs. In addition, the DEVELOPER and
ASSOCIATION and any new Owner must request that the PERMIT for the SCMs be re -issued to any subsequent
Owner.
The DEVELOPER and ASSOCIATION agree not to transfer, convey, assign or otherwise relinquish or release its
responsibility for the operation and maintenance of its SCMs until a PERMIT has been re -issued to DEVELOPER
and ASSOCIATION's successor, or new owner at which time DEVELOPER and ASSOCIATION shall be released
from any obligations hereunder arising from events or circumstances occurring after the date the SCMs are transferred
and the PERMIT is reissued to the new Owner of the PROPERTY.
4. Cost Estimates for Construction of the SCMs: The DEVELOPER's Engineer shall submit an
estimate of construction costs for review and approval by the TOWN in accordance and regulations with the
ORDINANCES. This cost estimate will be used to establish the level to which the escrow account shall be funded.
5. Establishment of an Escrow Account: For the purpose of insuring the availability of funds for the
long term maintenance and/or replacement/reconstruction of the SCMs, an escrow account must be established, which
can be spent solely for that purpose. Maintenance activities include, but are not limited to, sediment removal, and
structural, biological or vegetative replacement, major repairs, or reconstruction. If the SCMs are not performing
adequately or as intended or are not properly maintained, the TOWN in its sole discretion, may remedy the situation,
and in such instances, the TOWN shall be fully reimbursed from the escrow account.
Escrowed funds may be spent by the DEVELOPER, ASSOCIATION or ASSOCIATIONS's successor for allowable
expenses, provided that the TOWN shall first consent to the expenditure. Escrowed funds shall not be spent for routine
landscaping maintenance items such as mowing.
The escrow account will be funded initially by a lump sum contribution of the DEVELOPER (the "Initial Payment"),
and thereafter by annual sinking funds paid by the ASSOCIATION, if it has taken ownership or by the DEVELOPER
if it still retains ownership of the SCMs. The DEVELOPER shall deposit the Initial Payment in the escrow account
and show proof of such payment:
(i) Prior to plat recordation of the PROPERTY; or
(ii) Before the issuance of building permits for the construction of improvements on the PROPERTY.
Whichever occurs first.
Watershed and Stormwater Administrative Manual 39 Revised 2020-02-01
The Initial Payment shall be equal to $ dollars (which is equal to fifteen percent (15%) of the initial
construction costs of the SCMs).
The total sinking fund budget is defined as the amount required for the initial construction cost of the SCMs. The
ASSOCIATION shall deposit funds at least annually in equal installments into the escrow account such that at least
two-thirds (2/3) of the total amount of the sinking fund budget, as set in the ORDINANCES, shall be deposited into
the escrow account within the first five (5) years and the full amount shall be deposited within ten (10) years following
initial construction of the SCMs. A portion of the annual assessments of the ASSOCIATION shall include an
allocation into the escrow account. Any funds drawn down from the escrow account shall be replaced in accordance
with the schedule of anticipated work used to create the sinking fund budget.
6. The DEVELOPER shall provide in an Operation and Maintenance Plan (ATTACHEMENT A) that
specifies all necessary operation and maintenance procedures and that the SCMs, appurtenances and access easements
thereto shall thereafter be properly maintained and operated in conformity with ORDINANCES and the provisions of
the PERMIT.
7. The DEVELOPER and its successors shall grant to the TOWN a right of entry to inspect, monitor,
maintain, repair, and reconstruct SCMs.
8. The DEVELOPER and its successor hereby authorize the TOWN to recover from the DEVELOPER
or ASSOCIATION and its members, whichever is the responsible party, any and all costs the TOWN expends to
maintain or repair the SCMs or to correct any operational deficiencies. Failure to pay the TOWN all of its expended
costs, after forty-five days written notice, shall constitute a breach of the agreement. The TOWN shall thereafter be
entitled to bring an action against the responsible party to pay, or foreclose upon the lien hereby authorized by the
agreement against the PROPERTY, or both, in case of a deficiency. Interest, collection costs, and attorney fees shall
be added to the recovery.
9. This Agreement shall not obligate the TOWN to maintain or repair any SCMs, and the TOWN shall
not be liable to any person, firm, partnership, company, corporation, governmental agency, Association or entity for
the condition or operation of SCMs.
10. This agreement shall not in any way diminish, limit, or restrict the right of the TOWN to enforce
any of its ordinances as authorized by law.
11. Indemnification: Owners, DEVELOPER and/or ASSOCIATION agree to protect, defend,
indemnify and hold the TOWN, its officers, employees and agents free and harmless from and against any losses,
penalties, damages, settlements, costs, charges, professional fees or other expenses or liabilities in connection with or
arising out of this Agreement and/or related to the SCMs, unless the TOWN has agreed in writing to assume the
maintenance responsibility for the SCMs and has accepted dedication of any and all rights necessary to carry out that
maintenance.
12. A copy of this Operation and Maintenance Agreement shall be filed at the Forsyth (or Guilford, if
applicable) County Register of Deeds and in the office of the Watershed Administrator.

DESCRIPTION
(PER DEED)
Watershed and Stormwater Administrative Manual 47 Revised 2020-02-01
APPENDIX 10. a
Operation and Maintenance Plan:
"Name of the Pond or development": Wet Detention Pond
Dam Safety
Preserving the structural integrity of the wet detention pond's dam is important in protecting
downstream life and property. There are at least four aspects of the dam that require specific
attention: (1) assessment ofhazard potential due to changes in downstream development; (2)
leakage and seepage, (3) dam material problems; and (4) vegetation growth on the dam
embankments.
Assessment of Hazard Potential
Before any dam is constructed, the design engineer is responsible for notifying the NC State
Dam Safety Office of the proposed dam. If the dam falls under State Dam Safety jurisdiction,
the dam must be constructed, maintained, and operated according to their design and
construction guidelines. Even if the dam does not fall under the NC Dam Safety Office's
jurisdiction, the dam should be designed and constructed in accordance with current proper
engineering practices. The City has requirements concerning the maintenance of dams
associated with required wet detention ponds. As new development occurs downstream of the
pond, the chance of significant property damage or danger to human life may increase if
catastrophic failure of the dam occurs. Although the dam may be initially exempt from
regulation by the State, the owner is responsible for reporting to the State Dam Safety Office
downstream development that may affect the hazard classification of the dam.
Leakage and Seepage
The downstream side of the dam should be inspected regularly for evidence of significant
leakage or seepage. Seepage can emerge anywhere below the normal pool elevation, including
the downstream slope of earth dams, areas beyond the toe of the dam, and around the spillway or
pond outlet conduit. Indications of significant seepage include areas where the soil is saturated
or where there is a flowing "spring" or leak. If "sinkholes" in the dam embankment are noticed,
or if constant flowing water is noticed on the downstream side of the dam, then seepage has
become excessive and professional engineering advice should be sought immediately to avert a
major structural problem or a catastrophic failure of the dam.
Dam Material Problems
For earthen dams, pronounced cracks on the embankment surface indicate the first stages of
potential dam failure. Transverse cracks (running perpendicular to the embankment face)
generally indicating differential settlement of the dam, can provide pathways for excessive
seepage. Longitudinal cracks (running parallel to the embankment face) may be due to
inadequate compaction of the dam during construction or shrinkage of the clay (desiccation) in
the top of the embankment during prolonged dry conditions. These cracks may eventually lead
to slope failure, such as sliding or sloughing. For reinforced concrete dams, the concrete should
be checked for pronounced cracking, leakage from the joints, and displacement (noticeable
Watershed and Stormwater Administrative Manual 48 Revised 2020-02-01
leaning or bulging). Also, excessive seepage, leakage, or springs just downstream of the
concrete dam could be indicative of potential seepage -related "piping" problems under the dam.
If such problems or other structural problems are observed, professional engineering advice
should be sought.
Vegetative Growth
Trees and other woody vegetation are not permitted on the top, slopes, or embankments of
earthen dams. Large root systems from woody vegetation can weaken the dam structure and
provide seepage pathways. Thick vegetative cover can also provide a haven for burrowing
animals such as groundhogs and muskrats. These animals can create a network of burrows in the
dam embankments that can significantly weaken the dam, by creating seepage paths, which may
eventually lead to dam failure. Mowing of the dam embankments should occur, at a
minimum, once every 6 months to prevent woody vegetation from becoming established.
Pollution Prevention Activities
To assist the wet detention pond in improving the quality of stormwater runoff, every effort
should be made to reduce the pollutant load entering the pond system. The following onsite
efforts should be made to reduce pollutants from entering the pond:
• Outside trash dumpsters should be kept covered, and the area around the dumpster should be
kept neat and clean.
• Chemicals, petroleum products, and other pollution sources (such as machinery) should be
stored in a covered area away from possible stormwater contact. Spent chemicals are to be
properly disposed or recycled.
• Fertilizers and pesticides should be used conservatively on the property grounds. Excessive
amounts of these chemicals can be washed away with stormwater runoff, increasing the nutrient
load to the pond.
• Chemicals such as copper sulfate used to inhibit algal growth in the pond degrade water
quality. Since the pond's main function is to enhance water quality, these chemicals should not
be used. Rather, reducing the amount of fertilizer application and ensuring that the pond outlets
are properly functioning so the pool is flushed periodically will help to deter algal growth.
• Trash and vegetative floatables (grass clippings, leaves, limbs, etc.) should be cleaned from
the pond surface and surroundings periodically to promote a healthy, aesthetically pleasing
environment, and to prevent blockage of the pond outlets. Studies have shown that people are
less likely to litter ponds that are aesthetically pleasing and support wildlife.
Stabilization of Wet Detention Pond Drainage Area
The area draining to the wet detention pond should remain stabilized to prevent excessive
sediment from entering the pond. When bare soil is directly exposed to precipitation, the
sediment concentration in runoff is much higher than for soil that is covered and stabilized. A
stabilized area is covered by impervious surfaces (pavement, buildings), grass cover, landscaping
(mulch, pine straw), etc. It is in the best interest of the pond owner to reduce onsite sediment
runoff to the pond, as this will reduce the life span of the pond and result in the need for more
periodic, expensive dredging.
Embankments
If pond embankments are not kept well vegetated with grasses, erosion may occur. Erosion can
be repaired by filling the small channels and gullies with suitable soil, compacting, and seeding.
It may be necessary to install temporary erosion control (such as hay bales) along heavily eroded
areas to allow the repaired areas to stabilize. It is especially important to inspect for and
Watershed and Stormwater Administrative Manual 49 Revised 2020-02-01
immediately repair any erosion on the dam embankments.
Pipe Inlet and Outlet areas
Where erosion causes the undercutting of the downstream end of pipe, the undercut should be
stabilized immediately to prevent the end pipe section from "breaking" off. Eroded areas should
be filled with good compactable soil and covered with geotextile fabric and rip -rap.
Open Channel Flow
Eroded areas should be seeded/sodded and protected with temporary velocity dissipation (such as
excelsior matting, straw bales, etc.). If erosion continues, a more robust lining should be used.
Blockage of Outlets
Wet detention ponds are designed for the water to exit the pond through the low flow orifice(s),
the principal spillway, and the emergency spillway.
It is important to check all three outlets for blockage that would impair the pond's water quality
and hydraulic functionality.
Low Flow Orifice(s)
Unless an inverted orifice is used, some type of trash guard is to be maintained over the low flow
orifice(s) to prevent clogging. When the orifice becomes clogged the water level rises to the
principal spillway elevation and the benefits associated with temporary storage and its gradual
release are lost. To preserve "extended detention" the low flow orifice should be inspected for
blockage monthly, or after every runoff -producing rainfall event.
Principal and Emergency Spillway
Principal and emergency spillways are designed to safely convey one -inch rainfall events, and
those larger storms that produce runoff which exceed the water quality volume of the wet
detention pond. If these spillways are blocked so they do not operate at full capacity, the risk of
dam overtopping or other uncontrolled releases may result. To ensure the hydraulic capacity of
the spillways, the spillways should be inspected for blockage monthly, or after every
runoffproducing rainfall event.
If a riser/barrel is used for the principal spillway, a trash rack is to be maintained on the riser.
Vegetative growth in the riser should be removed promptly so that the design capacity of the
spillway is maintained. The emergency spillway and outlet area where the barrel projects from
the fill slope should be clear of woody vegetation, tree limbs, sediment accumulation, etc.
Sediment Accumulation
To preserve the wet detention pond's pollutant removal capability, sediment must be removed in
areas where the capacity of the design sediment storage volume has been exceeded. The pond
forebay helps to improve the removal efficiency of the pond system by trapping the majority of
coarser suspended solids behind a rock baffle. When sediment deposition in the forebay exceeds
the designed sediment storage capacity for the forebay, the forebay must be dredged. Typically,
forebays will need to be dredged every 5 to 10 years. Depth measurements relative to the normal
surface elevation (bottom of water quality orifice) should be taken at several locations around the
pond. The sediment is to be removed when the measured depth is less than the design permanent
water depth. Most wet detention ponds are designed for a three to four foot permanent water
depth. As sediment accumulates in the pond, the permanent water depth is reduced along with
the pond's ability to treat pollutants in the runoff. If a forebay is used at the inlet area of the pond
Watershed and Stormwater Administrative Manual 50 Revised 2020-02-01
and is regularly dredged, the frequency of dredging the entire pond could be greatly reduced.
Check water depth at various points in the pond semi-annually. If depth is reduced to 75 % of
the original design depth, sediment must be removed to at least the original design depth.
Sediment from most sources is usually not hazardous or contaminated, however, it is very
"soupy" and is difficult to manage. It is good idea to provide a storage area near the wet
detention pond to place sediment once it is dredged to allow it to dry. If desired, sediment may
be land applied and seeded, while following all pertinent soil and erosion control regulations. If
land applied on -site, it should be within the drainage area to the pond so sediment that runs off
can be recaptured.
Wet Detention Pond Maintenance
Routine Maintenance
Routine maintenance shall include minor upkeep such as mowing; trash and debris removal;
minor slope repair and stabilization; periodic structural inspections of the valves, gates, dam,
etc.; and tree and brush removal from the dam, spillway, inlet(s), and outlet. These maintenance
items may be performed by the owner without review of a Professional Engineer.
Non -Routine Maintenance
Non -routine maintenance shall include such items as sediment clean -out (dredging); channel
stabilization; and problems regarding the principal spillway conduits, emergency spillway, dam
failure, and seepage. These items require a Registered Professional Engineer to prepare a plan
and/or details and to certify completion of the maintenance. All revisions and repairs to
permanent runoff control structures shall be done in accordance with Town of Kernersville
guidelines and specifications.
Maintenance Schedule: (estimated schedule - certain ponds may require more or less frequent
Attention).
L Monthly, or after every runoff -producing rainfall event.
A. Remove trash and debris from the trash rack.
B. Check and clear the orifice of any obstructions.
C. Check the pond side slopes for erosion and remove trash from around the pond.
D. Inspect principal and emergency spillways for blockage.

D. Check riser and barrel for improper alignment, elongation and displacement of joints,
cracks, leaks, loss of protective coating, corrosion, and blockage - repair as necessary.
IV. General
A. Mow side slopes according to the season. Maximum grass height should be nine (9)
inches.
B. Riparian and aquatic vegetation (willows, alders, cattails, etc.) are encouraged along
the perimeter of the pond at the water's edge. However, the dam, emergency spillway,
inlet(s), and water control structure should be kept clear of all woody vegetation.
C. In case the ownership of the pond should change, the current owner should, within
thirty (30) days of transfer of ownership, notify the Town of Kernersville, Stormwater
Division of such ownership transfer.
D. Excessive plant growth, algae blooms, odors, discoloration, perceived animal pests,
etc. should be addressed with the Stormwater Division on an as -needed basis.

APPENDIX 10. b
(Name of the Bio-Cell) BIORETENTION AREA
OPERATION AND MAINTENANCE PLAN
The goals of this O&M Plan for a BMP structure is to specify all operation and
maintenance work necessary for the storm water control structure(s) and to provide
guidance to the current and any subsequent property owner on the requirements for
BMP inspection and maintenance. Also provide an estimation of the Annual Budget and
Replacement Fund necessary for the annual operation, inspection and maintenance
activities for the BMP.
Effective long-term operation of infiltration practices requires a dedicated and routine
maintenance inspection schedule with clear guidelines and schedules, as shown later
in this Plan. Where possible, facility maintenance should be integrated into routine
landscaping maintenance tasks.
The filter media and surface cover are the two most important elements of a
Bioretention facility in terms of long-term performance.
Common Maintenance Issues
Bioretention facilities require plant, soil, mulch, and under -drain maintenance to ensure
optimal infiltration, storage, and pollutant removal capabilities. Bioretention
maintenance requirements are typical landscape care procedures and include:
1. Watering: Plants should be selected to be tolerant of the bioretention facility's
particular conditions. Watering should not be required after establishment
(about 2 to 3 years). However, watering may be required during prolonged dry
periods after plants are established.
2. Erosion Control: Inspect flow entrances, ponding area, and surface overflow areas
periodically. Replace soil, plant material, and/or mulch in areas where erosion
has occurred. Erosion problems should not occur with proper design except
during extreme weather events. If erosion problems do occur, the following
issues should be re -assessed: flow volumes from the contributing drainage area
and bioretention size; flow velocities and gradients within the bioretention
facility; flow dissipation and erosion protection methods in the pretreatment and in -flow
areas. If sediment is deposited in the bioretention facility, immediately
determine the source, remove excess deposits, and correct the problem.
3. Plant Material: Depending on plants selected and aesthetic requirements,
occasional pruning and removal of dead plant material may be necessary.
Watershed and Stormwater Administrative Manual 60 Revised 2020-02-01
Replace all dead plants. However, if specific plants consistently have a high
mortality rate, assess the cause and replace with appropriate species. Periodic
weeding is necessary until groundcover plants are established. Weeding should
become less frequent if an appropriate plant density has been used.
4. Nutrients and Pesticides: The soil media and plant material should have been
selected for optimum fertility, plant establishment, and growth within the
particular conditions of each bioretention facility. Nutrient and pesticide inputs
should NOT be required and will degrade the pollutant processing capability of
the bioretention facility, as well as contribute to additional pollutant loading to
receiving waters. By design, bioretention facililities are typically specified in
watersheds where phosphorous and nitrogen levels are often elevated.
Therefore, these should not be limiting nutrients with regard to plant health. If
in question, have the soil analyzed for fertility.
5. Mulch: Bioretention areas should be mulched once the planting of trees and shrubs
has occurred. Replace mulch annually in Bioretention facilities where heavy metal
deposition is likely (e.g., drainage areas that include commercial/industrial uses,
parking lots, or roads). In residential or other settings where metal deposition is
not a concern, replace or add mulch as needed to maintain a 2 to 4 inch depth at
least once every two years.
6. Soil media: Soil mixes for bioretention facilities are design to maintain long-term
fertility and pollutant processing capability. Estimates from metal attenuation
research indicates that metal accumulation should not present a toxicity concern
for at least 20 years in bioretention facilities (USEPA 2000). Further, replacing
mulch where heavy metal deposition is likely provides an additional factor of
safety for prolonged bioretention performance. If in question, have soil analyzed
for fertility and pollutant levels.
With soil testing the accumulation of toxins and heavy metals can be detected or
prevented. Over a period of time, heavy metals and other toxic substances will tend to
accumulate in the soil and the plants. Data from other environs such as forest buffers
and grass swales suggest accumulation of toxins and heavy metals within five years of
installation. However, there is no methodology to estimate the level of toxic materials in
the bioretention areas since runoff, soil, and plant characteristics will vary from site to
site.
As the toxic substances accumulate, the plant biologic functions may become impaired,
and the plant may experience dwarfed growth followed by mortality. The biota within the
soil can also become void and the natural soil chemistry may be altered. The
preventative measures would include the removal of the contaminated soil. In some
cases, removal and disposal of the entire soil base as well as the plant material may be
required.
When the filtering capacity diminishes substantially (e.g., when water ponds on the
Watershed and Stormwater Administrative Manual 61 Revised 2020-02-01
surface for more than 12 hours), remedial actions must be taken. One possible problem
is that underdrain pipe systems can become clogged. Annual flushing through pipe
cleanouts is recommended to facilitate unclogging of the pipes without disturbing the
bioretention areas. If the water still ponds for more than 12 hours, the top few inches of
material should be removed and replaced with fresh material. The removed sediments
should be disposed of in an acceptable manner (e.g., landfill). If that does not solve the
problem, more extensive rebuilding is required.
Examples of When to Perform Maintenance
• Replace gravel when it has become clogged with sediment.
• Remove top layer of fill media when the pool does not drain quickly. The pool is
normally designed to drain within 12 hours.
Sample Operation and Maintenance Provisions
Important operation and maintenance procedures:
- Immediately after the Bioretention cell is established, the plants will be watered twice
weekly if needed until the plants become established (commonly six weeks).
- Snow, mulch or any other material will NEVER be piled on the surface of the
Bioretention cell.
- Heavy equipment will NEVER be driven over the Bioretention cell.
- Special care will be taken to prevent sediment from entering the Bioretention cell.
- Once a year, a soil test of the soil media will be conducted.
After the Bioretention cell is established, it should be inspected once a month and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location and
will be available upon request.
Ongoing monitoring and maintenance is vital to the overall success of bioretention
areas. Annual maintenance will be required for plant material, mulch layer, and soil
layer. Inspection activities shall be performed as follows. Any problems that are found
shall be repaired immediately.
