STATE STORMWATER MANAGEMENT PERMIT
HIGH DENSITY SUBDIVISION DEVELOPMENT
In compliance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations promulgated and adopted by the North
Carolina Environmental Management Commission, including 15A NCAC 02H.1000 amended on
January 1, 2017 (2017 Rules) (the "stormwater rules"),
PERMISSION IS HEREBY GRANTED TO
Carolina Land Group, LLC
Cotswold
Tippet Road and Roy Adams Road, Angier, Harnett County
FOR THE
construction, management, operation and maintenance of built -upon area (BUA) well as two (2) wet
ponds ("stormwater control measures" or "SCMs") as outlined in the application, approved stormwater
management plans, supplement, calculations, operation and maintenance agreement, recorded
documents, specifications, and other supporting data (the "approved plans and specifications") as
attached and/or on file with and approved by the Division of Energy, Mineral and Land Resources (the
"Division" or "DEMLR"). The project shall be constructed, operated and maintained in accordance
with these approved plans and specifications. The approved plans and specifications are
incorporated by reference and are enforceable part of this permit.
This permit shall be effective from the date of issuance until July 23, 2021 and shall be subject to the
following specified conditions and limitations. The permit issued shall continue in force and effect until
the permittee files a request with the Division for a permit modification, transfer, renewal, or
rescission; however, these actions do not stay any condition. The issuance of this permit does not
prohibit the Director from reopening and modifying the permit, revoking and reissuing the permit, or
terminating the permit for cause as allowed by the laws, rules, and regulations contained in Title 15A
NCAC 2H.1000 and NCGS 143-215.1 et.al.
BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 341,311
square feet. The runoff from all BUA within the permitted drainage areas of this project must
continue to be directed into the permitted SCMs. The following specific requirements pertain to
the BUA on this project:
a. SCM BUA LIMITS. The SCMs labeled DA1 and DA2 have been designed using the runoff
treatment method to handle the runoff from 291,016 square feet and 50,295 square feet of
BUA, respectively, within the delineated drainage areas. This permit does not provide any
allocation of BUA for future development within the delineated drainage area(s).
b. BUA FOR INDIVIDUAL LOTS. Each of the 111 lots are limited to a maximum of 2,463
square feet of BUA for single family lots and 1,485 square feet of BUA for townhomes, as
indicated in the approved plans and specifications. The maximum BUA assigned to each
lot via this permit and the recorded deed restrictions and protective covenants may
not be increased or decreased by either the individual lot owner or the permittee
unless and until the permittee notifies the Division and obtains written approval from
the Division.

Permit No. SW6210506
2. SCM REQUIREMENTS. The following requirements pertain to the SCMs on this project:
a. SCM DESIGN. The SCMs are permitted based on the design criteria presented in the
sealed, signed and dated supplement and as shown in the approved plans and
specifications. These SCMs must be provided and maintained at the design condition.
b. PLANTING PLAN. The SCM landscape planting plan shown in the approved plans shall be
followed in its entirety during construction. After the plants are established, the operation
and maintenance agreement must be followed.
c. FOUNTAINS. At this time, a decorative spray fountain has not been proposed within the wet
pond. Decorative spray fountains will be allowed in the wet pond if documentation is
provided demonstrating that the proposed fountain will not cause resuspension of sediment
within the pond or cause erosion of the pond side slopes.
d. IRRIGATION. If the wet pond is to be used for irrigation, it is recommended that some water
be maintained in the permanent pool, the vegetated shelf is planted with appropriate species
that can handle fluctuating conditions, and human health issues are addressed.
3. STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not cause
erosion downslope of the discharge point.
4. VEGETATED SETBACKS. A 50-foot wide vegetative setback must be provided and maintained
in grass or other vegetation adjacent to all surface waters as shown on the approved plans. The
setback is measured horizontally from the normal pool elevation of impounded structures, from
the top of bank of each side of streams or rivers, and from the mean high waterline of tidal
waters, perpendicular to the shoreline.
a. BUA IN THE VEGETATED SETBACK. BUA may not be added to the vegetated setback
except as shown on the approved plans or in the following instances where the BUA has
been minimized and channelizing runoff from the BUA is avoided:
i. Water dependent structures; and
ii. Minimal footprint uses such as poles, signs, utility appurtenances, and security
lights that cannot practically be located elsewhere.
b. RELEASE OF STORMWATER NOT TREATED IN AN SCM. Stormwater that is not treated
in an SCM must be released at the edge of the vegetated setback and allowed to flow
through the setback as dispersed flow.
5. RECORDED DOCUMENT REQUIREMENTS. The stormwater rules require the following
documents to be recorded with the Office of the Register of Deeds prior to the sale of individual
lots or arouos of lots:
a. ACCESS AND/OR EASEMENTS. The entire stormwater conveyance system, including any
SCMs, and maintenance accesses must be located in public rights -of -way, dedicated
common areas that extend to the nearest public right-of-way, and/or permanent recorded
easements that extend to the nearest public right-of-way for the purpose of inspection,
operation, maintenance, and repair.
b. OPERATION AND MAINTENANCE AGREEMENT. The operation and maintenance
agreement must be recorded with the Office of the Register of Deeds.
c. FINAL PLATS. The final recorded plats_must reference the operation and maintenance
agreement and must also show all public rights -of -way, dedicated common areas, and/or
permanent drainage easements, in accordance with the approved plans.

V. Alteration of the drainage as shown on the approved plans may not take place
without the concurrence of the Division.
vi. The maximum built -upon area (BUA) per lot is 2,463 square feet for single family
lots and 1,485 square feet for townhomes. This allotted amount includes any BUA
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 not shown on the approved
plans. BUA has the same meaning as G.S. 143-214.7, as amended.
vii. For those lots within the CAMA Area of Environmental Concern, where DCM
calculates a different maximum lot BUA, the governing maximum lot BUA shall be
the more restrictive of the two amounts.
viii. The maximum allowable BUA shall not be exceeded on any lot until the permit is
modified to ensure compliance with the stormwater rules, permit, and the approved
plans and specifications.
ix. All runoff from the BUA on the lot must drain into the permitted system. This may
be accomplished via grading, a stormwater collection system and/or a vegetated
conveyance.
X. A 50-foot wide vegetative setback must be provided and maintained adjacent to all
surface waters in accordance with 15A NCAC 02H.1003(4) and the approved
plans.

a SCM, the permittee shall provide and perform the operation and maintenance as outlined
in the applicable section below.
b. SCM RESTORATION. If one or more of the SCMs are used as an Erosion Control device
and/or removed or destroyed during construction, it must be restored to the approved state
stormwater design condition prior to close-out of the erosion control plan and/or project
completion and/or transfer of the state stormwater permit. Upon restoration, a new or
updated certification will be required for the SCM(s) and a copy must be submitted to the
appropriate DEQ regional office.
