This is a Neuse Buffer only request for two stormwater conveyances directly through the
buffer. The applicant has proposed two bioretention areas outside to provide nutrient removal. The
designs appear to meet the criteria set forth in our Stormwater BMP Manual and should provide
adequate nitrogen removal.

Re: Bioretention Area Design for Brackenridge Pointe r-
Holly Springs, Wake County
DWQ # 001360
S&N Project # 196-00
Dear Mr. St. John,
Brackenridge Pointe is a residential subdivision in Holly Springs that drains to the Neuse River
basin. As required, level spreaders are supplied at the discharge points of all concentrated storm
flows. However, it is the professional opinion of Mrs. Heather Keefer, Town of Holly Springs
Environmental Inspector and myself that two proposed level spreader locations are not suitable
for level spreaders due to excessively steep slopes. For these two locations, the Owner proposes
to install bioretention areas, designed according to the April 1999, NCDENR, Stormwater Best
Management Practices manual. It is our understanding that the installation of properly designed
bioretention areas is acceptable for this situation. This letter is a request for your written approval
of their design and installation in the place of level spreaders as indicated on the attached plans.
Supporting calculations are included with this letter for your reference.
Thank you in advance for your time spent reviewing this request. Please do not hesitate to call
me if you have any questions, comments or concerns about this request or if you require
additional information to process this request.
Sincerely,
Scott Mitchel , , LSS

Bioretention Area Design Calculations
for
Brackenridge Pointe
Both Bioretention Areas were designed using guidelines published in the April 1999,
NCDENR - Stormwater Best Management Practices Manual.
Bioretention Area "E"
Drainage Area = 1.02 acres
Rational "C" = 0.35
No sand bed proposed, so minimum required Bioretention Area =
1.02 acres x 43,560 ft2/acre x 0.35 x 0.07 = 1, 9 ft2
Proposed Bioretention Area "E" = 55 ft x 20 ft = 1,100 ft2
Bioretention Area "F"
Drainage Area = 0.35 acres
Rational "C" = 0.35
No sand bed proposed, so minimum required Bioretention Area =
0.35 acres x 43,560 ft2/acre x 0.35 x 0.07 = 374 ft2
Proposed Bioretention Area "F" = 40 ft x 15 ft = 600 ft2
(Minimum dimensions recommended for bioretention areas)
CulvertMaster and FlowMaster output sheets used to design the proposed 12-inch HDPE
pipe into Bioretention Area "E" and both permanent rip-rap lined trapezoidal channels
are attached to this calculation sheet. Shear stress calculations for the permanent
trapezoidal channels are also included on these output sheets. Lastly, tables from the
North Carolina Erosion and Sediment Control Planning and Design Manual indicating
recommended Manning's Roughness Coefficients and Permissible Unit Shear Stresses
are attached for your reference and as supporting documentation for calculations.

DETERMINING SHEAR STRESS
Shear stress, T, at normal depth is computed for the lining by the following
equation:
T=yds
Td = Permissible shear stress
where:
T shear stress in lb/ft2
y = unit weight of water, 62.4 lb/ft3
d = flow depth in ft
s = channel gradient in ft/ft.
If the permissible shear stress, Td, given in Table 8.05g is greater than the
computed shear stress, the riprap or temporary lining is considered acceptable.
If a lining is unacceptable, select a lining with a higher permissible shear stress
and repeat the calculations for normal depth and shear stress. In some cases it
may be necessary to alter channel dimensions to reduce the shear stress.
Computing tractive force around a channel bend requires special considerations
because the change in flow direction imposes higher shear stress on the channel
bottom and banks. The maximum shear stress in a bend, Tb, is given by the
following equation:
Tb = KbT
where:
Tb = bend shear stress in lb/ft2
Kb = bend factor
T = computed stress for straight channel in Ib/ft2
The value of Kb is related to the radius of curvature of the channel at its center
line, Rc, and the bottom width of the channel, B, Figure 8.05e. The length of
channel requiring protection downstream from a bend, Lp, is a function of the
roughness of the lining material and the hydraulic radius as shown in Figure
8.05F.

Design Procedure- The following is a step-by-step procedure for designing a temporary liner for a
Temporary Liners channel. Because temporary liners have a short period of service, the design Q
may be reduced. For liners that are needed for six months or less, the 2-yr
frequency storm is recommended.
Step 1. Select a liner material suitable for site conditions and application.
Determine roughness coefficient from manufacturer's specifications or Table
8.05e, pg. 8.05.10.
Step 2. Calculate the normal flow depth using Manning's equation (Figure
8.05d). Check to see that depth is consistent with that assumed for selection of
Manning's n in Figure 8.05d, pg. 8.05.11. For smaller runoffs Figure 8.05d is
not as clearly defined. Recommended solutions can be determined by using the
Manning equation.
Step 3. Calculate shear stress at normal depth.
Step 4. Compare computed shear stress with the permissible shear stress for
the liner.
Step 5. If computed shear is greater than permissible shear, adjust channel
dimensions to reduce shear or select a more resistant lining and repeat steps 1
through 4.
Design of a channel with temporary lining is illustrated in Sample Problem
8.05b, pg. 8.05.14.
