Academi — Dining Facility
High Density Stormwater Project
Camden County
Dear Mr. Stock:
The Washington Regional Office received a Stormwater Management Permit
Application for ownership change of the subject project on October 28, 2019. Staff
review of the application has determined that the permit can be reissued. We are
forwarding Permit No. SW7060812 dated December 9, 2019, for the continued
operation of the subject project.
This permit, upon its effective date, will replace all previous State Stormwater permits for
this project. This permit shall be effective from the date of issuance until September 20,
2020 and shall be subject to the conditions and limitations as specified therein, and does
not supercede any other agency permit that may be required. 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

➢ Please provide a temporary and permanent seeding schedule for proposed vegetated areas.
➢ Please provide energy dissipaters (including cross sectional details) at the pipe and swale outlets
that lead into the pond forebays.
➢ Please verify that the temporary pool elevation for this wet pond will be 10.55 finsl and not 10.25
fmsl as noted on the Wet Detention Basin Supplement forth.
The above requested information must be received in this office prior to September 14, 2006 or
your application will be returned as incomplete. The return of this project will necessitate resubmittal of

Footnotes:
t When using the Division SAMA tables, the correct SAMA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 in the 20 coastal counties, the requirement for a vegetative filter may be waived if (lie wet detention basin is designed to provide
90% TSS removal. The NCDFNR SMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
II. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section: 15 A NCAC 21-1 .1008.
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached. If the applicant has designated an agent in the Stormwater Management Permit
Application Form, the agent may initial below. If a requirement has not been met, attach justification.
Applicants Initials
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 runoff from the design storm event.
d. The temporary pool draws down in 2 to 5 days.
d./A e. If required, a 30-foot vegetative filter is provided at the outlet (include non -erosive flow
calculations)
f. The basin length to width ratio is greater than 3:1. (APPVX. 2a1
g. The basin side slopes above the permanent pool are no steeper than 3:1.
h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
i. Vegetative cover above the permanent pool elevation is specified.
j. A trash rack or similar device is provided for both the overflow and orifice.
k. A recorded drainage easement is provided for each basin including access to nearest right-
of-way.
I. If the basin is used for sediment and erosion control during construction, clean out of -the
basin is specified prior to use as a wet detention basin.
m. A mechanism is speeified which will drain the basin for maintenance or an emergency.
I11. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the
vegetated filter if one is provided.
This system (check one) 0 does does not incorporate a vegetated filter at the outlet.
This system (check one) 0 does does not incorporate pretreatment other than a forebay.

Maintenance activities shall be performed as follows:
l . After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
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). Removed sediment shall be disposed of
in an appropriate manner 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 detemnne the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through
the emergency drain shall be minimized to the maximum extent practical.
