Subject: Stormwater Permit Renewal
Stormwater Management Permit SW7070712
Tanglewood Lakes Apartments
Pasquotank County
Dear Mr. Franklin:
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7070712 for a stormwater treatment system consisting of three
wet detention ponds serving Tanglewood Lakes Apartments located at 3895 Waterside
Drive, Elizabeth City, NC expires on December 20, 2021. This is a reminder that permit
renewal applications are due 180 days prior to expiration. We do not have a record of
receiving a renewal application.
Please submit a completed permit renewal application along with a $505.00 fee for
permit renewal within the required time. Permit application forms for renewal can be
found on our website at: hftps:l/deq.nc.gov/about/divisions/energy-mineral-and-land-
resources/stormwater/stormwater-program/post-construction-2. North Carolina General
Statutes and the Coastal Stormwater rules require that this property be covered under a
stormwater permit. Failure to maintain a permit subjects the owner to assessment of
civil penalties.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application forms. You can request a copy by e-mailing me at

Subject: Tanglewood apartments Stormwater permit
Heather
I was copied on the e-mail correspondence between you and our administrative assistant, Della Robins. I wanted to let
you know that stormwater permit SW7070712 does not expire until December 20, 2021, even though the permit says
that it expires on December 20, 2017. Back in 2008 the NC legislature administratively extended all permits by four
years. Della mentioned to you that a designers certification is needed. That is still true and it was required to be
submitted once the apartments were constructed. You should go ahead and submit that now. Sorry for the confusion.
Thanks
Roger

Dear Mr. Hodge:
Please find enclosed two (2) sets of construction documents for the development of the
above referenced project, and a check for 5420.00 (application processing fee). The
Tanglewood Apartments site is located off Halstead Boulevard extended on Tanglewood
Parkway in Elizabeth City. The proposed project is the first phase of a 312 unit
apartment site. The first phase will consist of 180 apartment units.
Three wet detention basins are proposed to handle water quality. All three ponds
discharge into a 60 acre borrow pit that has been master planned to handle the water
quantity for the proposed project and other adjacent sites. The water quality calculations
are included with this submittal.
Also enclosed for your review are the following:
2 copies of the Project Narrative and Calculations Package

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 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

FormSWU-102 Rev3.99 Page 2of4

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 315- feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3 .:R3- feet in the forebay, the sediment shall be removed.

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.

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.
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? f feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads -3S feet in the forebay, the sediment shall be removed.
