POST -CONSTRUCTION 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
Toll Southeast LP Company, Inc.
Hemby Place
13301 Providence Road, Weddington, Union County
FOR THE
construction, management, operation and maintenance of built -upon area (BUA) draining to one (1)
wet pond ("stormwater control measures" or "SCMs") discharging to Sixmile Creek 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 March 16, 2030 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 314,339
square feet. The runoff from all BUA within the permitted high density drainage area of this
project must be directed into the permitted SCM. The BUA requirements and allocations for this
project are as follows:
a. SCM BUA LIMITS. The SCM has been designed to handle the runoff from 304,045 square
feet of BUA within the delineated drainage area. This permit does not provide any allocation
of BUA for future development within the delineated drainage area. This permit approves
10,294 square feet of BUA that was not able to be collected and treated in an SCM due to
topographic constraints to bypass the system.
Page 1 of 7

Post -Construction Stormwater Management
Permit No. SW3211201
b. BUA FOR INDIVIDUAL LOTS. Each of the thirty-five (35) lots 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 SCM 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
SCM must be provided and maintained at the design condition.
b. GOOSE CREEK WATERSHED. The SCM controls and treats the difference in the pre- and
post -development runoff volumes for the one-year, 24-hour storm event, promotes infiltration
and groundwater recharge, and discharges the runoff at a rate less than or equal to the pre -
development condition for the purpose of maintaining stream base flow.
c. ALTERNATIVE DESIGNS. The wet pond is permitted as a variation to the requirements
outlined in 15A NCAC 02B .0602(a) per 15A NCAC 02H.1003(6). The proposed wet pond
design has been found to promote infiltration and groundwater recharge since the on -site
soils are well drained, Hydrologic Soil Group (HSG) "B" soils and the wet pond does not
contain a liner which allows some of the captured stormwater runoff to infiltrate into the
underlying soils and recharge the groundwater. The proposed project has been found to
provide equal or better stormwater control and equal or better protection of surface waters.
If the proposed project is modified and no longer meets the intent of the stormwater rules, a
modification must be submitted to either meet the requirements or propose another variation
from the rules. This is based on a case -by -case decision and should not be used as a
precedent for future permitting actions.
d. 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.
e. 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.
f. 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. STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not cause
erosion downslope of the discharge point.
5. VEGETATED SETBACKS. A 100-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.
Page 2of7

Post -Construction Stormwater Management
Permit No. SW3211201
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.
6. 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
perpetuity. Recorded deed restrictions and protective covenants must include, at a minimum,
the following statements related to stormwater management:
i. The following covenants are intended to ensure ongoing compliance with
Stormwater Management Permit Number SW3211201, as issued by the Division of
Energy, Mineral and Land Resources (the "Division") under 15A NCAC 02H.1000,

the express written consent of the Division.
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 as shown in Attachment B. 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. 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.
viii. 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.
ix. A 100-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.
X. Any individual or entity found to be in noncompliance with the provisions of a
stormwater management permit or the requirements of the stormwater rules is
subject to enforcement procedures as set forth in NCGS 143, Article 21.
