Access Storage
High Density Stormwater Project
Brunswick County
Dear Ms. Houston:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for Access Storage on October 3, 2002. 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 2H.1000. We are forwarding Permit No. SW8 020727 dated October
11, 2002, for the construction of Access Storage.
This permit shall be effective from the date of issuance until October 11, 2012, and shall be
subject to the conditions and limitations as specified therein. Please pay special attention to the
Operation and Maintenance requirements in this permit. Failure to establish an adequate system
for operation and maintenance of the stormwater management system 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 upon written request within thirty (30) days following
receipt of this permit. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative
Hearings, P.O. Drawer 27447, Raleigh, NC 27611-7447. Unless such demands are made this
permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please contact
Linda Lewis, or me at (910) 395-3900.
Sincerely,
V�'L� C—. Lz

permit.
This permit shall be effective from the date of issuance until October 11, 2012, and shall be
subject to the following specified conditions and limitations:
I. DESIGN STANDARDS
1. This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data.
2. This stormwater system has been approved for the management of stormwater runoff as
described on page 3 of this permit, the Project Data Sheet. The stormwater control has
been designed to handle the runoff from 112,275 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.
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.

a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet)-
b. The forebay volume is approximately equal to 20% of the basin volume.
c. The temporary pool controls nmoff from the design smarm event.
d. The temporary pool draws down in 2 to 5 days.
e. If required, a 30-foot vegetative filter is provided at the outlet (include non -erosive flow
calculation)
f. The basin length to width ratio is greater than 3:1.
g. The basin side slopes above the permanent pool are no stems than 3:1.
h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
L Vegetative cover above the permanent pool elevation is spccfied.
j. A trash rack or similar device is provided for both the overflow and orifice.
k. A recorded drainage easenwnt is provided for each basin inchuiing access to nearest q;ht-
V of -way.
L if the basin is used for sediment and erosion control during construction, dean out of the
basin is specified prior to use as a wet detention basin.
m. A mechanism is specified which wiU drain the basin for maintenance or an emaergency.
IIL WET DETENTION BASIN OPERATION AND MAINTENANCE AGENT
The wet detention basin system is defined as the wet detention basin, gretreatineut including fouebays and the
vegetated-frltex if one is provided..
Thou system (check one)
0 does
does not
incorporate a vegetated) toter at the outlet.
This system (check one)
0 does
does not
hwarporate p twent other than a forebay.
Maintenance activities shall be performed as foIlows:.
1. After every significant nmoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment won, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and ckair the orifice of any obsumcdons such that drawdown of the temporary pool occurs
within 2 to 5 days as de i md-
2. Repair eroded at+eas m-seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and move trash as needed.
3. fnspect and repair the collection system (Le. catch basins, piping, swaks, ripraup, etc.) quarterly to
maintain proper fnncxioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Remmved sediment shad be disposed
of in an appropriate mane and shall, be handled in a manner that will not adversely impact water quality
(i.e. stockpiling near a wet detention basin or stream, etc,).
The measuring device used to detmmine ft sediment elevation shall be such- that it will give an acxa m&
depth reading and not really penetrate into accamulated sedi:nents.
When the permanent pool depth reads 4.5 feet in the main pond, the sediment shall he removed.
Wbuea the pm anent pool depth Leads 3.0 feet in the fambay, the sediment shall be removed.

through the emergency drain shall be minimized to the maximum extent practical.
7. All components of dw wet detention basin system shall be maintained in good wodang order.
