Using Surface Area to Drainage Area Ratio Chart for 90% TSS Removal (copy attached) and
assuming 4 94 foot pond depth
SA/DA = 4 52 % (interpolated - Select from Highlighted Cell in SA/DA)
Therefore
Surface Area = SA/DA x Drainage Area
= 20,830 SF say 20,841 SF
must be > 20,830 SF
c Compute Minimum Pond Dimensions

ee v vV
APR 2 9 2014
BY !/5
Min Length = 249 98 feet
Min Width = 83 33 feet
Site conditions, however dictate irregular shaped pond
Hydr Length = 370 0 feet
so Hydr Width (a\ 56 3 feet (avg)
Actual L/W = 6 6 (irregular shape)
3 DETERMINE REQUIRED STORAGE VOLUME
Design Rainfall Depth = 1 5 inches
Using Schuler "Simple Method"
Rv = 0 05 + 0 009(I) where I = percent impervious
Rv = 0 611 in/in
Control Volume = Design Rainfall x Rv x Drainage Area
Control Volume = 35 170 CF

Assume 3 1 side slopes
solving for depth (d) by trial & error
d = 1 54
5 DETERMINE ORIFICE SIZE
SaYNNME37 173 CF
Must be > 35.170 SF
Control Volume must be drawn down over a 2 day - 5 day penod
Using orifice equation solve for Diameter (D) that results in 3-1/2 day penod
D=(Q/0026(h)e)e
Where Q = (Control Volume / 3 5 days x 86 400 sec/day)
0 123 cfs
h=D/3
=051
Solving for D
D = 257 Use 3 00 " pipe
Actual Drawdown with actual drawdown pipe diameter (using orifice equation)
Q= 0 168 cfs
Draw Down Period = 2 43 days OK, < 5 0

6 SELECT OUTLET STRUCTURE SIZE

Using Rational Formula (Q=CIA) where
Cimper = 0 8
Cpery = 02
Ccum = 056
110 = 7 50 in/hr
A = 10 57 ac
Q10 = 44 01 cfs
Using Francis Formula (Q=3 OLH' 5) to solve for L such that H = 1 5 Feet
Min L = 7 986 Linear Feet
Use 12 Linear Foot Weir
Use 5 Square Precast Structure
7 DETERMINE Q10 STAGE
Q10 = 44 01 cfs
From Routing Analysis, H10 = 2 39

Ccum =

1100 = 9 50 in/hr
A=

Q100 = 55 75 cfs
From Routing Analysis H100 = 2 83
9 DETERMINE Q100 STAGE OVER EMERGENCY SPILLWAY (TOP BERM ELEV )
Assume primary spillway blocked (i a emergency spillway to accommodate Q100)
Emergency spillway shall be a broad crested earthern weir designed to pass 100 year storm

Stormwater Treatment Narrative
FCW&P Properties, LLC
FCW & P Properties, LLC owns a undeveloped 7 63 acre tract that includes an existing
stormwater wetland, that wetland sized and permitted to accommodate several existing
adjacent tracts Those adjacent tracts include several existing uses, including a portion of
a CVS drug store (SW8 070804 Mod), a "Jones Car Wash" (SW8 110713 ), and one
additional undeveloped tract The original permit for the stormwater wetland was issued
on 8/18/11 (SW8-110712)
FCW& P Properties, Inc now desires to abandon the stormwater wetland and construct,
in its place, a Wet Pond, that Wet Pond sized as to accommodate ALL existing tributary
BUA, as well as additional BUA associated with new proposed development on the
remaining FCW&P tract The new Wet Pond wills serve a total drainage area of 460,345
sf (10 57 Ac)
The project site is located in the White Oak River basin The tract is currently cleared
with most runoff draining to adjacent ditches and wetland basins From there the flow
runs into a nearby unnamed tributary of New River (C, NSW) The site is relatively flat
(0 6%-1 5% slopes)
The proposed development activities are high density (percent impervious > 24%),
therefore, stormwater treatment facilities are required The attached Stormwater Plan
includes a wet detention basin located within the designed Stormwater lot at the eastern
section of the site This pond has been designed to meet the Coastal Rules, and according
to current BMP Manual Specifications The stormwater pond has been designed with a
connected forebay and main pond Runoff generated from impervious surfaces on and
off site will be diverted to the forebay via inlets and underground storm dram pipes
Treated Stormwater will exit the main pond via an new outlet structure and new 36"
outlet pipe and into the nearby drainage ditch across the Southern side of the Western
