Edenton Cotton Mill
Redevelopment Stormwater Project
Chowan County
Dear Mr. Yates:
The Washington Regional Office received a completed Stormwater Application for the subject project on March 23,
2004. 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. SW7040310 dated April 8, 2004
to Edenton Cotton Mill Development, Inc. for the construction and operation of wet detention pond to serve the redevelopment
of the Edenton Cotton Mill site located in Edenton, NC.
This permit shall be effective from the date of issuance until April 8, 2014 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, 6714 Mail Service Center, Raleigh, NC 27699-6714. 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 Roger Thorpe at

Al,
We were contacted by the architects for the above referenced project and asked to
provide the Designer's Certification for the detention pond. I am not sure why you had
not previously received this, but I have attached a copy from our file.
We have not been asked to inspect the pond's current state or assist in any way other
than providing a copy of the certification. If you need anything else from our office,
please feel free to contact us.
Thank you,

Footnotes:
When using the Division SA/DA tables, the correct SA/DA 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.
In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
H. 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

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.
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.
Kh _ 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.
kd-h j.
A trash rack or similar device is provided for both the overflow and orifice.
k.

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 specified which will drain the basin for maintenance or an emergency.
III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the

Attachment to WET DETENTION BASIN SUPPLEMENT
For Edenton Cotton Mill
a. The permanent pool depth is 7'. The depth was increased to allow an SA/DA
ratio that can provide 90% TSS removal at the surface area provided. Surface
area was limited as this is an existing site that is being renovated.
b. The forebay volume is approximately 14% of the total pond volume. This is due
to the increased total pond volume that is created by the additional depth.
e. Pond has been designed for 90% TSS removal.
The length to width ratio is less that 2:1. The area available to construct the pond
is limited as this is an existing site that is being renovated.
k. The basin discharges through wetlands adjacent to Queen Anne's Creek. The
property crossed is owned by the developer.
M. Emergency drain would have to be located below the seasonal water table. Pond
must be emptied by pumping.
Maintenance activities shall be performed as follows:
1. 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 determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 5.2 5 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 2. 2 5 feet in the forebay, the sediment shall be removed.

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.
