Dear Ms. Moore:
The Wilmington Regional Office received a complete 8 year Stormwater Management Permit Renewal
Application for the subject project on. The Division is hereby notifying you that permit SW8 120911 has been
renewed on February 12, 2021, and shall be effective until November 28, 2028. Please keep this permit on file at
all times. Please note that the renewed, updated, and re -issued permit does not impose new or different terms; it
merely restates some of the previous terms to provide you with a better understanding of your obligations under
the permit.
The renewal and reissuance of this stormwater permit does not imply that the site is currently in compliance with
the terms and conditions of this state stormwater permit. The plans originally approved on November 28, 2012
and most recently modified on September 16, 2015, will remain in full force and effect in accordance with the
regulations set forth in Title 15A NCAC 2H.1000. This permit is issued in the original permittee's name and will
be transferred in a separate action after this issuance.
This permit is subject to the conditions and limitations as specified therein. Please pay special attention to the
conditions listed in this permit regarding the Operation and Maintenance of the BMP(s), recordation of deed
restrictions, procedures for changes of ownership, transferring the permit, and renewing the permit. Failure to
establish an adequate system for operation and maintenance of the stormwater management system, to record
deed restrictions, to transfer the permit, or to renew the permit, will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request
an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The
written petition must conform to Chapter 150B of the North Carolina General Statutes, and must be filed with the
OAH within thirty (30) days of receipt of this permit. You should contact the OAH with all questions regarding
the filing fee (if a filing fee is required) and/or the details of the filing process at 6714 Mail Service Center,
Raleigh, NC 27699-6714, or via telephone at 919-431-3000, or visit their website at www.NCOAH.com. Unless
such demands are made this permit shall be final and binding.
If you have any questions, need additional copies of the permit or approved plans, please contact Daniel Sams in
the Wilmington Regional Office, at [phone] or [e-mail].
Sincerely,
i

Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond 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 should be kept in a known set
location and must be available upon request.

Lantana Crossing Operational and Maintenance Policy and Procedures
The Purpose of this Policy and Procedure:
This stormwater management policy and procedure includes a designed summary for the
Lantana Crossing stormwater Operational and Maintenance BMP, design calculations, plans
and specifications showing inlet and outlet structure details, routine pond maintenance, such
as mowing and removing debris or trash, is needed multiple times each year. Inspection
Frequency for the inspection will be conducted on a monthly basis for minor items, and
annually for major inspection items, such as structural components for both ponds,
Pond #1 located on Morning Glory Court and Pond #2 located on Albemarle Court.
More significant maintenance such as removing accumulated sediment is needed less
frequently but requires more skilled labor and special equipment and may need a separate
proposal submitted to the Association Manager and the work will not be performed until the
approval has been obtained by the Board of Directors. At which time the Proposal for
Additional services will be signed by the Association Manager or by a CEPCO administrative
staff member.
Monthly Inspections for the months of December, January, and February, And Bi-monthly
inspections for the months of March through November.
The Monthly Inspection will also include the following items:
1. Items that are missing such as manhole covers or trash racks, missing or damaged fencing
that normally prevents access to a pond with steep side slopes, or a missing or damaged
grate at a large inflow or outfall pipe.
2. A Pond Inspection Report will contain all of the pertinent documentation regarding the
inspector's findings, additives used on the pond, any indications of bare spots or erosions
that are observed, the date, time and Inspector's signature, and recommendations.
3. Inspectors should take a core set of documentation through photographs depicting the
practices being inspected. In addition, specific problem areas should be photo
documented. A recommended set of core photographs for ponds and wetlands include:
• Vehicle access points.
• Overview of practice. L—
• Overview of principal spillway structure.
• Upstream face of dam embankment. FEB 0 5 2021
• Downstream face of dam embankment.
• Outfall to practice and downstream outfall from practice. BY'
• Emergency spillway (if applicable). In addition, because of the large number of
photographs that will likely be generated, a digital camera should be used when possible
to allow photographs to be stored electronically. (In advanced database programs, these
photographs can be retrieved digitally). Finally, photographs should be named using a
standard convention. The photograph name should indicate the practice identification
number, feature (or problem) being photographed, and date of photograph.
Field Marking is a very important practice for the inspector to ensure that key areas have
been highlighted as an area of concern with spray paint or another form of marker.

This is particularly useful for problems that may otherwise be difficult to find by others.
Marking should be used as discretely as possible. For example, only dots sprayed at the
base of trees should be used to mark limits of clearing for vegetation removal.
5. In addition to routine inspection, maintenance needs to be performed to access the
function of the control structure. Runoff treatment controls require specific maintenance
activities at varying schedules. The cost and time commitment should be planned for all
maintenance activities delegated to the contractor unless the proposal for additional
services have been submitted to the Association Manager and approved by the Board of
Directors which include but are not limited to the following items:
• Cleaning and removing debris after major storm events (>2" rainfall)
• Harvesting of vegetation when a 50% reduction in the original open water surface area
occurs
• Repairing embankment and side slopes
• Repairing control structure annually or as needed due to storms and debris
• Removing accumulated sediment from forebays or sediment storage areas when 60% of
the original volume has been lost 5-year cycle Ponds Extended detention ponds, wet
ponds, multiple pond systems, "pocket' ponds
• Removing accumulated sediment from main cells of pond once 50% of the original
volume has been lost 20-year cycle.
• Inspection and repair of critical structural features such as embankments and risers.
6. The structural stability issues associated with embankments and pipes, earth, concrete and
metal repairs are essential elements of stormwater pond and wetland maintenance and
designed for a stable water surface elevation between storm events that will rise during
and shortly after a significant rain event. Pond elevations should not dip appreciably below
the specified level unless under extreme conditions, such as drought. Pools provide
functions including aquatic habitat, water quality protection, and visual aesthetics. When
pool levels drop too low, water quality is threatened by algal blooms and anoxic conditions,
which can lead to fish kills and plant stress that in turn can undesirably reduce predation on
mosquito larvae. Leaks within the facility embankment or through the bottom of the pond
are often difficult to locate unless they are large or severe. Active dam leaks often produce
a vortex, an unmistakable indication of a leak. Water may leak through sinkholes formed in
pond bottoms or infiltrate through porous underlying soils. Leaks in the principal spillway
riser are easy to spot. Leaks in the barrel are harder to locate, as they require either
manual entry or remote TV inspection. Broken or missing valves can also lead toward
abnormally low water levels in ponds.
7. Clogged low flow orifices and weirs represent the most frequent, persistent maintenance
item common to all types of ponds or wetlands. Serious impacts can easily be minimized
through design and retrofit. However, without frequent maintenance, even openings with
trash racks can become clogged. Clogging occurs when debris or sediment accumulates at
riser/weir openings or outfalls, blocking the flow of water. Debris includes vegetative
material such as dead plants, twigs, branches and leaves as well as litter and trash. Large
storms can transport large amounts of debris. Vandalism and nuisance problems such as
beavers contribute to clogging as well.

8. The high permanent pool disrupts the pond or wetland function by:
a. Decreasing storage volume thereby reducing the ability to attenuate flood flows.
b. Causing the flow velocity leaving the pond or wetland to be greater than the design
release rates therefore increasing downstream channel erosion.
c. Compromising water quality because runoff short -circuital the pond and enters the
downstream channel without adequate residence time for quality treatment.
d. Abnormally high permanent pool — Water spills into 2- year weir because beavers
have clogged the low flow orifice.
e. Killing riparian trees by flooding their roots which are not normally submerged in the
high pool.
f. Compromising public access and safety when adjacent pathways and recreational use
areas are flooded.
g. Saturating areas designed to be outside the permanent pool potentially causing
mosquito -breeding habitat to be created. (Basins should be designed so that pooling
or ponding of water in isolated peripheral areas does not occur for more than 4
consecutive days.
9. In addition to the permanent pool fluctuation problems noted above, clogged orifices can
cause the following concerns:
a. Riser without trash rack
b. Flattop riser covered with debris.
c. Obscuring the upstream slope of embankments, preventing adequate inspection.
d. Blocking low flow openings causing overtopping of the embankment or dam in the
event of a flood.
e. Blocking underwater spillway inlets such as 'reverse slope' pipes once floating debris
becomes waterlogged and sinks. Pipe Repairs Pipes and riser structures are designed to
convey stormwater safely and at a controlled rate. If pipes or risers are damaged, these
functions will be affected. Often, risers are made from the same materials as pipes, and
therefore can be treated as such with respect to maintenance and repair. Pipes through
the embankment — the principal spillway and other utilities —are designed to be
watertight. If damaged, pipes may leak water into the embankment through holes or
separated joints. This can lead to piping of water along the pipe, which results in
erosion and can lead to embankment failure. Pipe damage can occur at any point in a
pond or wetland lifecycle and can be caused by improper d poor construction,
inadequate maintenance, or wear and tear.
10. Vegetation Management Vegetation management involves sustaining the landscaping as
designed and preventing the growth of unwanted species. There are three primary types
of vegetation that require management and maintenance in stormwater ponds and
wetlands: turf and grasses, wetland plantings, and trees and forested areas.

11. Turf and Grasses Native and non-native grasses are the most common vegetative
stabilization used in stormwater pond and wetland construction today for reasons of
aesthetics, ease of maintenance, and price (Figure 1.6). The root system of any vegetative
cover holds the surface soil in place and protects the slopes from wind and surface runoff
erosion. A regularly scheduled program of cutting and trimming of grass at facilities during
the growing season will help to maintain a tightly knit turf and will also help prevent
diseases, pests, and the intrusion of weeds.
12. Wetland Plantings Native wetland plants promote biological uptake of pollutants. Though
natural propagation is desirable, vegetation will still need to be managed to meet the
design goals. Depending on the design of the system, vegetation harvesting3 and control of
aquatic plants (such as cattails and phragmites) may be required. Trees are often planted
for aesthetic, stabilization, and temperature control reasons. They must be maintained to
prevent clogging of orifices with debris and the spread to unwanted areas. Vegetation
management is probably the most frequent maintenance activity that occurs in association
with the upkeep of stormwater ponds and wetlands. While the activity requires little
expertise or special equipment, there are still important site conditions to be aware of to
maintain a properly functioning stormwater pond or wetland.
13. Unseen areas may be neglected. For example, the downstream dam face of an
embankment is the most commonly neglected and most critical area requiring regular
clearing.
a. Heavy pedestrian use, particularly along the top of the pond and along pond edges
can create patches of bare soil.
b. Industrial pollutants can cause alteration in the chemical composition and pH of the
discharge water, which, in turn, can affect plant growth even when the source of
contamination is intermittent. Nutrients increase plant growth and acidic discharges
can decrease vegetation.
c. Un-maintained vegetation can obscure large portions of the dam, preventing
adequate visual inspection and limiting access to the dam and surrounding areas.
And obstructing the access is critical in emergency situations.
d. Excessive vegetation often provides habitat for rodents and burrowing animals and
can affect the flow rates through earthen spillways.
14. Sources of solid and semisolid wastes retained in a pond or wetland include:
• Soil loss from lawns and open areas
• Litter and yard waste
• Sand from winter sanding operations
• Natural leaf litter and down branches
• Grit from roofing shingles
• Atmospheric deposition wash off
• Construction sediments
• Erosion from upstream conveyance swales
• Asphalt grit as sediment accumulation

15. Sediment forebays, pond drains, access for sediment removal,
and a designated onsite disposal area. These considerations will reduce eventual costs
of sediment removal, as major cost items in dredging include dewatering, transport of
sediment for off -site disposal, re-establishment of wetland communities, and accessing
the site.
16. Nuisance Issues include:
1. Rodents damage ponds or wetlands through burrowing or dam building.
2. Burrowing may jeopardize embankment stability for dams and berms; beaver
dam building reduces live storage and creates clogging problems.
3. The following animals routinely cause destruction to embankments and berms
groundhogs/woodchucks, muskrats, prairie dogs, badgers, pocket gophers and
Richardson ground squirrels. Animal burrows can deteriorate the structural
integrity of dams, embankments and cause erosion.

Inspect/on Frequency
Ponds and wetlands should ideally be inspected on a monthly basis for minor items, and annually for
major inspection items, such as structural components. In reality, many communities are unable to inspect
all of their ponds this frequently, and a more typical scenario is providing inspection once every,*ee
years. This less frequent full inspection 'can be supplemented with a routine inspection conducted by a
property owner or contractor responsible for maintenance` In the case of wetlands,'an additional'
inspection may be required after the first year to ensure that wetland plantings remain viable.

Inspectlon Checklists
A community,should use standard inspection checklists to record the condition of all practices, and
particularly those that need frequent maintenance. Most communities'will find iteasier to"track
maintenance electronically, using either a database or spreadsheet, rather than relying on paper files.
r;. Well-designed'c6eeklists can be integrated with these systems to prioritize maintenance, track '
;t�• performance'over time, and relate design characteristics to particular problems. To effectively achieve
these goals; the checklist should:
* Be quantitative, so that maintenance can be easily prioritized.
Be very specific about possible problems to reduce subjectivity.
:. Be concise with text particularly if integrated with a ditaba
be inundated with too much text. se; so that the checklist user will not
Link problems to specific actions.
'£ Where possible, trick the function of the pond or wetland over time for future research and
design.
Inspection checklists should also be grouped in the order the inspector would inspect the practice. For
example, ponds should typically be inspected from downstream to upstream, so the investigation begins
with the outfall channel. Sample checklists are presented in Appendix B.
For additional example checklists, consult SMRC (www.stormwatercenter.net). Checklists can be found
by clicking "Program Resources" then "STP Maintenance" and "Maintenance Checklists, Reminders, and
Notifications." In addition to providing detailed "professional" checklists for various BMPs, it also
includes a'simplified pond inspection checklist for homeowners. A Pond -Wetland Maintenance Checklist
can also be found as part of Tool M6 of the Post -Construction Guide (www•cwp,orglp&stconstruction).
Documentation of Inspection Findings
Inspectors should clearly identify the extent and location of problems identified during inspection. In
addition to clearly describing problem areas on the checklists, inspectors should help repair crews locate
repairs both at the site and on design plans.
/mmediate Concerns
While all maintenance and inspection items are important, some maintenance concerns actualan
immediate safetyconcern. Many of these are caused by missing or damaged elements that wly ould pose
normally prevent access by the public. Examples include missing manhole covers or trash racks, missi
or damaged fencing that normally prevents access to a pond with steep side slopes, or a missing or ng
damaged grate at a large inflow or outfall pipe.
Another set of immediate pond and wetland repairs involve dam safety or Flooding hazards. If a practice
shows signs of embankment failure, or if an inspector is unsure, an appropriately qualified person or

High Density Residential Subdivisions
Deed Restrictions & Protective Covenances
In accordance with Title 15 NCAC 2H.1000 and S.L. 2006-246, the Stormwater Management Regulations,
deed restrictions and protective covenants are required for High Density Residential Subdivisions where
lots will be subdivided and sold and runoff will be treated in an engineered stormwater control facility. Deed
restrictions and protective covenants are necessary to ensure that the development maintains a "built -upon"
area consistent with the design criteria used to size the stormwater control facility.
1, 0 rlDG , Li, L , acknowledge, affirm and agree by my signature below, that I will
cause the following deed restrictions and covenants to be recorded prior to the sale of any lot:
The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number 51..) R — 12,0911 , as issued by the Division of Water Quality under the
Stormwater Management Regulations.
2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to
maintain compliance with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties claiming under
them.
4. The covenants pertaining to stormwater may not be altered or rescinded without the express written
consent of the State of North Carolina, Division of Water Quality.
5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence
of the Division of Water Quality.
6. The maximum allowable built -upon area per lot is 3, .57J0 square feet. This allotted amount
includes any built -upon area constructed within the lot property boundaries, and that portion of the
right-of-way between the front lot line and the edge of the pavement. Built upon area includes, but is not
limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and parking areas, but does
not include raised, open wood decking, or the water surface of swimming pools.
OR, if the proposed built -upon areas per lot will vary, please REPLACE #6 above with the following:
6. The maximum built -upon area per lot, in square feet, is as listed below:
Lot # BUA Lot # BUA Lot # BUA Lot # BUA
This allotted amount includes any built -upon area constructed within the lot property boundaries, and
that portion of the right-of-way between the front lot line and the edge of the pavement. Built upon area
includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and
parking areas, but does not include raised, open wood decking, or the water surface of swimming
pools.
7. Each lot will maintain a 30** foot wide vegetated buffer between all impervious areas and surface
waters.
**50 foot for projects located in the 20 coastal counties.
8. All runoff from the built -upon areas on the lot must drain into the permitted system. This may be
accomplished through a variety of means including roof drain gutters which drain to the street, grading
the lot to drain toward the street, or grading perimeter swales to collect the lot runoff and directing them
into a component of the stormwater collection system. Lots that will naturally drain into the system are
not required to provide these additional measures.
