Subject: Stormwater Permit No. SW3161202
Millbridge Phase 8 Residential Subdivision
High Density Wet Detention Basins
Waxhaw, Union County
The Stormwater Permitting Unit received a complete package for the Millbridge -- Phase 8
Residential Subdivision on December 22, 2016. Staff review of the plans and specifications has
determined that the project, as proposed, will comply with the Stormwater Regulations set forth
in Title 15A NCAC 21-1.1000 and Session Law 2006-246. We are forwarding this Stormwater
Management Permit No. SW3170101, issued January 11, 2017, for the construction, operation
and maintenance of the subject project and the stormwater BMPs.
This permit shall be effective from the date of issuance until January 11, 2025, and shall be
subject to the conditions and limitations as specified therein, and does not supersede any other
agency permit that may be required. 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 follow the procedures for transfer of 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. Per NCGS 143-215(e) the petition 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.

* Impervious area is defined as the built upon area including, but not limited to, buildings, roads, parking areas,
sidewalks, gravel areas, etc.
Report only that amount of existing BUA that will remain after development. Do not report any existing BUA that
is to be removed and which will be replaced by new BUA.
11. How was the off -site impervious area listed above determined? Provide documentation. The survey for the
project included the topography of the adjacent phase/parcels. The offsite area drainingto o the project was
delineated and the built upon area in the offsite area was measured in CADD
Projects in Union County: Contact DEMLR Central Office staff to check if the project is located within a Threatened &
Endangered Species watershed that may be subject to more stringent stormwater requirements as per 15A NCAC 02B .0600.
V. SUPPLEMENT AND O&M FORMS

I will keep a maintenance record on this BMP. This maintenance record will be kept in a

corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.

— Immediately after the wet detention basin is established, the plants on thW_
vegetated shelf and perimeter of the basin should be watered twice week y 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.

I will keep a maintenance record on this BMP. This maintenance record will be kept in a

of structures, safety of the public, and the removal efficiency of the BMP.

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.

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.
J
I, David Hughes 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:
1. The following covenants are inte ed o gns}�re ongoing compliance with State StormwW
Management Permit Number to / s issued by the Division of Energy, Wral ao
Land Resources under the Stormwater Management Regulations. /` s

2. The State of North Carolina is made a beneficiary of these covenants to the extent necess r�y o �

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 Energy, Mineral and Land Resources.
5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence
of the Division of Energy, Mineral and Land Resources.
6. The maximum allowable built -upon area per lot is 3500 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

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.
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.
