Harnett County
Dear Mr. Song:
The Division of Energy,Mineral and Land Resources received a complete Minor Modification Application for
changes to the subject permit and project on May 10, 2023. Staff review has determined that the proposed
changes meet the definition of a minor modification in that it does not result in an increase in the size of the
permitted stormwater control measure(SCM) and does not increase the amount of built-upon area. Please refer
to Attachment C for a detailed description of the current proposed minor modification and a list of all the past
modifications approved during the effective period of the permit. The Division is hereby notifying you that the
permit SW6210904 has been modified,updated, and re-issued on August 2, 2023, as attached,to reflect any
changes. Please replace the previous application page, Supplement-EZ page, and proposed deed restrictions
and protective covenants with the attached modified versions. Please replace the previously approved plan
sheet(s)with the approved modified version(s)enclosed.
This permit remains effective until November 29,2029 and does not supersede any other agency permit that
may be required. The project shall be subject to the conditions and limitations as specified therein,including
the requirement to revise or amend the recorded deed restrictions with the updated built-upon area
allocations. This permit does not impose new or increased stormwater control requirements or design
standards; it clarifies the rules and requirements of this program to provide you with a better understanding of
your obligations under this permit. Failure to comply with these requirements will result in future compliance
problems. Please note that this permit is not transferable except after notice to and approval by the Division.
This project will be kept on file at the Fayetteville Regional Office. If you have any questions concerning this
permit,please contact Jim Farkas in the Central Office, at(19)707-3646 or [e-mail].
Sincerely,

This permit shall be effective from the date of issuance until November 29, 2029 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 15A
NCAC 02H.1000 and NCGS 143-215.1 et.al.
1. BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is
1,853,038 square feet. The runoff from all BUA within the permitted high density drainage areas
of this project must be directed into the permitted SCMs. The BUA requirements and allocations
for this project are as follows:
a. HIGH DENSITY AREA SCM BUA LIMITS. The SCMs labeled Wet Pond #3 and Wet Pond
#4 have been designed to handle the runoff from 624,828 square feet and 1,018,519 square
feet of BUA, respectively, within the delineated drainage areas. The BUA for future
development within the drainage areas to the SCMs labeled Wet Pond #3 and Wet Pond #4
is limited to 22,911 square feet and 74,466 square feet, respectively.
b. LOW DENSITY AREA BUA LIMITS. The low density area, also referred to as Drainage
Area 3 in the approved plans and specifications, must not exceed 12% per the requirements
of the stormwater rules. Within this low density area, this permit approves a percent BUA of
12% and the construction of a total of 209,691 square feet of BUA, which includes 51,385
square feet of future BUA allocation.

142, 144-168, 170-307, 323-347, 364-462 are limited to a maximum amount of BUA as
indicated in Attachment B of this permit and 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.
2. PERVIOUS AREA IMPROVEMENTS. At this time, none of the pervious area improvements
listed in G.S. 143-214.7(b2) or the Stormwater Design Manual have been proposed for this
project. Pervious area improvements will be allowed in this project if documentation is provided
demonstrating those improvements meet the requirements of the stormwater rule.
3. SCM REQUIREMENTS. The SCM requirements for this project are as follows:
a. SCM DESIGN. The SCMs are permitted based on the design criteria presented in the
sealed, signed and dated supplements 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.
4. LOW DENSITY AREA REQUIREMENTS. The low density area requirements for this project are
as follows:
a. LOW DENSITY AND CONVEYANCE DESIGN. The low density area is permitted based on
the design criteria presented in the sealed, signed and dated supplement and as shown in
the approved plans and specifications. This low density area and conveyances must be
provided and maintained at the design condition.
b. PIPING. Other than the piping shown on the approved plans, only minimal amounts of
piping under driveways and roads is allowed within the low density area when it cannot be
avoided. No additional piping is allowed.
c. DISPERSED FLOW. The low density area has maximized dispersed flow of stormwater
runoff through vegetated areas and minimized the channelization of flow.
d. VEGETATED CONVEYANCES. Stormwater runoff that could not be released as dispersed
flow may be transported by vegetated conveyances with minimum side slopes of 3:1 (H:V)
designed to not erode during the peak flow from the 10-year storm event as defined in the
stormwater rules and approved by the Division.
5. STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not cause
erosion downslope of the discharge point.
6. VEGETATED SETBACKS. A 30-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.

Permit No. SW6210904
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, such as in the low density area (including roof drains), must be released at the
edge of the vegetated setback and allowed to flow through the setback as dispersed flow.
7. 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 groups of lots:
a. EASEMENTS. All SCMs, stormwater collection systems, vegetated conveyances, and
maintenance access located on property owned by other persons or entities must be located
in permanent recorded easements or drainage easements as shown on the approved plans.
b. OPERATION AND MAINTENANCE AGREEMENT. The operation and maintenance
agreement must be recorded with the Office of the Register of Deeds.
c. FINAL PLATS. If a final plat is recorded, it 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.
d. DEED RESTRICTIONS AND PROTECTIVE COVENANTS. The permittee shall record deed
restrictions and protective covenants prior to the issuance of a certificate of occupancy to
ensure the permit conditions and the approved plans and specifications are maintained in

Permitting History
Original Permit— Issued November 30, 2021
The entire Serenity Subdivision area (approximately 321.76 ac) was originally permitted under
a single permit (SW6200201) with the possibility to modify the permit for subsequent phases. It
was decided to permit portions of the subdivision area under separate permits so Phases 1 D-
E, 2C-G, & 6A-G were separated out from the original permitted area and permitted under
their own permit (SW6210904).
Minor Modification #1 — Issued August 2, 2023
Two lots (143 & 169) are removed, Lot 170 has its BUA allocation increased by 506 sf, Lot 278
has its BUA reduced by 350 sf, Lot 295 has its BUA allocation increased by 900 sf, Lot 298
has its BUA allocation decreased by 350 sf, & Lot 299 has its BUA allocation decreased by
350 sf resulting in a net decrease in BUA of 4,704 sf. This net decrease in BUA was converted
to future BUA allocations so as to not change the total amount of BUA associated with this
project or the drainage areas. The total future BUA allocated to Wet Pond #3 is now 22,911 sf,
the total future BUA allocated to Wet Pond #4 is now 74,466 sf, and the total future BUA
allocated to the Low-Density area is now 51,385 sf.
