PERMISSION IS HEREBY GRANTED TO
Jon T. Vincent, Bradley Point, LLC
Dollar General Castle Hayne
6001 Castle Hayne Road, New Hanover County
FOR THE
construction, operation and maintenance of a wet detention pond in compliance with the
provisions of 15A NCAC 2H .1000 (hereafter referred to as the "stornrwater rules') and the
approved stormwater management plans and specifications and other supporting data as attached
and on file with and approved by the Division of Water Quality and considered a part of this
permit.
This permit shall be effective from the date of issuance until May 5, 2013, and shall be subject to
the following specified conditions and limitations:
1. DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data.
2. This stornrwater system has been approved for the management of stornrwater runoff as
described on page 3 of this permit, the Project Data Sheet. The stornrwater control has
been designed to handle the runoff from 124,234 square feet of impervious area
3. The tract will be limited to the amount of built -upon area indicated on page 3 of this
permit, and per approved plans. The built -upon area for the future development is limited
to 66,940 square feet.
4. All stormwater collection and treatment systems must be located in either dedicated
common areas or recorded easements. The final plats for the project will be recorded
showing all such required easements, in accordance with the approved plans.
5. The runoff from all built -upon area within the permitted drainage area of this project
must be directed into the permitted stormwater control system. A permit modification
must be submitted and approved prior to the construction of additional built -upon area
from outside of the approved drainage area.

II. SCHEDULE OF COMPLIANCE
1. The stormwater management system shall be constructed in it's entirety, vegetated and
operational for its intended use prior to the construction of any built -upon surface.
2. During construction, erosion shall be kept to a minimum and any eroded areas of the
system will be repaired immediately.
3. The permittee shall at all times provide the operation and maintenance necessary to
assure the permitted stormwater system functions at optimum efficiency. The approved
Operation and Maintenance Plan must be followed in its entirety and maintenance must
occur at the scheduled intervals including, but not limited to:
a. Semiannual scheduled inspections (every 6 months).
b. Sediment removal.
C. Mowing and revegetation of slopes and the vegetated filter.
d. Immediate repair of eroded areas.
C. Maintenance of all slopes in accordance with approved plans and specifications.
f. Debris removal and unclogging of outlet structure, orifice device, flow spreader,
catch basins and piping.
g. Access to the outlet structure must be available at all times.
4. Records of maintenance activities must be kept and made available upon request to
authorized personnel of DWQ. The records will indicate the date, activity, name of
person performing the work and what actions were taken.
5. Decorative spray fountains will not be allowed in the stormwater treatment system.
6. The facilities shall be constructed as shown on the approved plans. This permit shall
become voidable unless the facilities are constructed in accordance with the conditions of
this permit, the approved plans and specifications, and other supporting data.
7. Upon completion of construction, prior to issuance of a Certificate of Occupancy, and
prior to operation of this permitted facility, a certification must be received from an
appropriate designer for the system installed certifying that the permitted facility has been
installed in accordance with this permit, the approved plans and specifications, and other
supporting documentation. Any deviations from the approved plans and specifications
must be noted on the Certification. A modification may be required for those -deviations.
8. If the stonnwater system was used as an Erosion Control device, it must be restored to
design condition prior to operation as a stormwater treatment device, and prior to
occupancy of the facility.
9. The permittee shall submit final site layout and grading plans for any permitted future
areas shown on the approved plans, prior to construction. If the proposed BUA exceeds
the amount permitted under this permit, a modification to the permit must be submitted
and approved prior to construction.
10. A copy of the approved plans and specifications shall be maintained on file by the
Permittee for a minimum of ten years from the date of the completion of construction.

In response to your correspondence dated November 1, 2002, we offer the
following:
1. We have noted "preliminary site investigation by owner's consultant shows no
wetlands on site. Consultant to verify with USACOE prior to construction."
2. A delineation of the proposed 4.11 acre drainage basin has been provided. Off
site runoff has been routed around the proposed pond.
3. a baffle has been added within the main pool and off set spillway within the
forebay wall to provide a 3:1 L: W flow path.
4. Vicinity map has been revised to provide location from two major roads.
5. The existing ditch invert at our pipe outlet is +12.0. We have revised our outlet
pipe to be well above this.
6. Pond dimensions for the permanent pool contour have been provided.
Please review for approval and contact us with any questions, comments or if you
need additional information. Thank you.

REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 020819
Dollar General Castle Hayne
New Hanover County -' -
. The Wilmington Regional Office received a Stormwater Management Permit Application
for Dollar General Castle Hayne on August 20, 2002. A preliminary review of that information
has determined that the application is not complete. The following information is needed to
continue the stormwater review:
1. Please either delineate all wetlands on site, disturbed or undisturbed, or note on
the plans that none exist.
2. Please delineate the 4.11 acre drainage area. Based on the existing and proposed
contours from the residential tract to the west, and from the existing Bullock
Tract, it appears that more than 4.11 acres of drainage area will drain to this pond,
and more than 124,343 ft2 of built -upon area will ultimately drain to this pond.
You must show how the runoff from these areas will bypass the pond. If this
additional drainage area is not diverted, the surface area provided will be
deficient.
3. Please provide a 3:1 L:W flow path ratio in the pond. The proposed pond provides
slightly over a 2:1 ratio. There is plenty of room to provide this ratio.
4. Please add the nearest intersection of two major roads to the vicinity map. A
major road is any 1, 2 or 3 digit NC, US or interstate highway.
5. The bottom of the outlet ditch is approximately 0.5' above the bottom of the outlet
structure pipe and approximately 2' above the existing pipe under the ABC Store
parking lot. This will cause the pond to not draw down to the permanent pool
elevation of 13. Please either raise the permanent pool elevation above the
anticipated normal flow elevation in the ditch, or excavate the ditch to provide a
clear outlet to the receiving stream.
6. Please provide dimensions for each line and arc of the figure created by the
permanent pool contour.

sf of building area along with 38,282 sf of asphalt parking and 2,386 sf of concrete
sidewalk. An impervious area of 66,940 sf will be reserved for development in the future.
All areas will be treated by wet detention for the State's l" and the County's 25-year pre -
post requirements, then discharge to Prince George Creek, classification C-SW.
