Edenton Medical Park
High Density Subdivision Project
Chowan County
Dear Mr. Bassett:
The Washington Regional Office received a complete Stormwater Management Permit
Application for Edenton Medical Park on September 1, 2006. 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.
SW7060521, dated September 21, 2006 to Paradigm Development Group, LLC for
modification to an existing wet detention pond to serve the proposed roadway improvements,
the BB&T site, Filbert Creek Apartments, and lots 3-10 located on Claire Drive in Edenton,
NC.
This permit shall be effective from the date of issuance until September 21, 2016, and shall
be subject to the conditions and limitations as specified therein. This permit shall replace
permit SW7041113 issued April 4, 2005. 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 Scott Vinson, or me at [phone].

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.
2 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 901/6 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 2H .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
JHB
a.
The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
JHB
b.
The forebay volume is approximately equal to 20% of the basin volume.
JHB
c.
The temporary pool controls runoff from the design storm event.
JHB
d.
The temporary pool draws down in 2 to 5 days.
N/A
e.
If required, a 30-foot vegetative filter is provided at the outlet (include non -erosive flow
calculations)
JHB
f.
The basin length to width ratio is greater than 3:1.
JHB
g.
The basin side slopes above the permanent pool are no steeper than 3:1.
JHB
h.
A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
JHB
i.
Vegetative cover above the permanent pool elevation is specified.
JHB
j.
A trash rack or similar device is provided for both the overflow and orifice.
JHB
k.
A recorded drainage easement is provided for each basin including access to nearest right-
of-way.
N/A
1.
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.
JHB
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
vegetated filter if one is provided.
This system (check one) 0 does 0 does not incorporate a vegetated filter at the outlet.
This system (check one) 0 does 8 does not incorporate }pretreatment other than a forebay.
Form SWU-102 Rev 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
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.
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 -�3^ feet in the main pond, the sediment shall be removed.
3.75(
When the permanent pool depth reads ­1-3' 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.
Form SWU-102 Rev 3.99 Page 3 of 4

7. All components of the wet detention basin system shall be maintained in good working order.
1 acknowledge and agree by my signature below that I am responsible for the performance of the seven
maintenance procedures listed above. 1 agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.
