POST -CONSTRUCTION STORMWATER MANAGEMENT PERMIT
LOW DENSITY 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
Water and Sewer Authority of Cabarrus County (WSACC)
Rocky River Regional Wastewater Treatment Plant Phase 3 Expansion Design
6400 Breezy Lane, Concord, Cabarrus County
FOR THE
construction, management, operation and maintenance of built -upon area (BUA) for one (1) area of
redevelopment (the "redevelopment area") and a low density area (the "low density area(s)") as
outlined in the application, approved stormwater management plans, supplements, 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 parts of this
permit.
This permit shall be effective from the date of issuance until rescinded and shall be subject to the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, 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 2H.1000
and NCGS 143-215.1 et.al.
BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 669,016
square feet. The BUA requirements and allocations for this project are as follows:
a. REDEVELOPMENT. The redevelopment portion of this project is exempt from permitting
requirements under the following conditions:
i. The project must be constructed as shown on the submitted plans.
ii. The redevelopment area proposes 563,516 square feet of BUA, which does not
exceed the existing BUA of 573,000 square feet. This permit does not provide any
allocation of BUA for future development within this redevelopment area.
iii. The proposed stormwater control provides equal protection of surface waters as
the existing stormwater control.
b. LOW DENSITY AREA BUA LIMITS. The low density area must not exceed 24% per the
requirements of the stormwater rules. Within this low density area, this permit approves a
percent BUA of 6.54% and the construction of a total of 105,500 square feet of BUA, which
includes 40,600 square feet of future BUA. This permit excludes 573,000 square feet of
existing BUA in accordance with 15A NCAC 02H.1003(1)(b).

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. 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.
4. NON -ENFORCEABLE STORMWATER CONTROL MEASURE (SCM). The sedimentation
basins and other facilities solely associated with the treatment of wastewater shown on the
plans are not required by the Division and have not been demonstrated to meet the Minimum
Design Criteria and therefore are not considered a part of the approved stormwater treatment
system. These additional measures are incorporated only by reference and are not enforceable
parts of the permit.
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.
a. BUA IN THE VEGETATED SETBACK. BUA may not be added to the vegetated setback
except as shown on the approved plans;
b. RELEASE OF STORMWATER NOT TREATED IN A STORMWATER CONTROL
MEASURE (SCM). Stormwater that is not treated in an SCM, such as in this low density
project (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:
a. EASEMENTS. All 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.
