Bojangles — Chocowinity
High Density Project
Dear Mr. McRae: Beaufort County
The Washington Regional Office received a complete Stormwater Management Permit
Application for Bojangles - Chocowinity on November 25, 2009. Staff review of the plans and
specifications has determined that the project, as proposed, will comply with the Stormwater
Regulations set forth in Session Law 2008-211 and Title 15A NCAC 2H.1000. We are
forwarding Permit No. SW7091119 dated January 29, 2010 for the construction of the subject
project.
This permit shall be effective from the date of issuance until January 29, 2020, 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 150E 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 Samir Dumpor, or me at [phone].

B. CALCULATIONS
1.�The orifice is sized based on drawing down the calculated minimum volume in 2-5
days. The average head to use in the orifice equation is approximately one-third of
the distance between the permanent pool elevation (PPE) and the elevation of the
next available outlet above the permanent pool. The elevation of the next available
outlet must be either the elevation where the minimum volume is provided, or it can
be higher. The temporary pool elevation (TPE) to report on the supplement will be
the elevation of the next available outlet above the PPE. The temporary pool volume
(TPV) to report on the supplement is the volume between the specified PPE and the

Tor
Phase 11 projects that are within 1/2mile of and draining to SR waters, the
1difference in runoff from the predevelopment and post -development conditions for
the 1 year 24 hour storm must be controlled and treated.
3 4� � For Phase II projects, the discharge rate leaving the pond can be no more than the
/�( pre -development discharge rate for the 1 year 24 hour storm.
4 11 For Phase II projects draining to SA water, no discharge to surface waters may occur
from wet ponds. The discharge leaving the orifice must be effectively infiltrated prior to
�reaching surface waters.
5/�I The average pond depth is the permanent pool volume divided by the permanent pool
iflII'' surface area. The result must be between 3 ft. and 7.5 ft. Parts of the pond can be
--// deeper than 7.5 ft., but in no case can any part of the pond be less than 3 ft deep.
6;JjJ�- If the 85%TSS chart is used a 30' vegetated filter must be provided at the outlet of the
//,/ pond. If the 90% TSS chart is used, no filter is required.
7. V Use the correct SA/DA TSS chart from the BMP Manual noting that there are different
/ charts for different areas of the State.

10.0 Required volume calculation based on 1.5" storm for Phase II projects* and 1" storm for
all others projects. *unless the project is Phase II and within '/2 mile of and draining to
SR waters then the volume calculation must be based on difference between the pre
and post development conditions for the 1-yr 24-hr storm.

14 The seasonal high water table must be at or below the proposed permanent pool
elevation to assure that the necessary volume will be available above the permanent

15. Rounding numbers off during the calculation process can result in deficiencies. Do not
,/round the numbers until you get to the final result.
16. An additional one foot must be excavated below the bottom elevation of the pond. The 1
foot sediment accumulation depth is not included in the average depth calculation.

C. PLANS- Due to storage space constraints, plan sheets should be kept to a minimum. For
small commercial single wet pond projects, the plan set could consist of only 2 or 3 sheets,
layout, grading and details. For larger projects, show as much information as possible on as
few sheets as possible, without cluttering them up.

24. A, forebay is provided for each inlet and located so as to prevent short-circuiting.
25. The pond must have a minimum 1.5:1 length to width ratio and a minimum 3:1 flow path
length. Artificial "baffles" of timber, vinyl, or earth can be used to create a longer flow
path. The top elevation of the baffle should be set at the temporary pool elevation or
higher.
26. A Vegetation plan is specified for the pond, including slopes. Wetlands species are
listed for planting on the 10:1 shelf. Weeping Love Grass is not suitable as a permanent
,vegetated cover for pond slopes.
27. All roof drainage must be directed to the pond. Show the roof drain collection lines on
the plan. This is necessary for projects where the buildings back up the property lines
where roof drainage may leave the site prior to going through the pond.
