described in the application and other supporting data
2 This stormwater system has been approved for the management of stormwater
runoff as described in Section 16 on page 3 of this permit The stormwater
control has been designed to handle the runoff from 232,920 square feet of
impervious area

Maintenance activities shall be performed as follows
After every significant runoft producing rainfall event and at least monthly
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 drawdow n 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
3 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 )

We are requesting Express Permit Review for the referenced project (Stormwater and Erosion Control)
This is the first project we will be submitting with the new procedure, so we may need guidance We
contacted your office as a first step but have not yet received a reply We are including in this fax the
Request for Express Permit Review, a Vicinity Map, Narrative, and Express Permitbng Questionnaire
As I understand it, if the project is accepted for Express Review, the next step would be to schedule a
submittal meeting

Stormwater Treatment &
Erosion Control Narrative
Affordable Self Storage
TWC Enterprises proposes to construct a self storage facility on a 7 29 acre tract located on US 17 North just
north of Jacksonville The site is currently undeveloped
The protect site is located approximately 0 2 miles from Northeast Creek (SC,NSW) in the White Oak Basin
The proposed development activities are high density (percent impervious > 30 %), therefore, stormwater
treatment facilities are required The attached Stormwater Plan includes a 13,245 sf wet detention basin at the
southern side of the site
The pond is sized to accommodate 150,981 square feet of impervious area associated with the proposed
protect In addition, the pond is sized to accommodate an additional 81,939 sf of impervious area which may
be constructed in the future (permit modification required)
The proposed pond is sized for 90% TSS removal The pond does not incorporate pretreatment, other than
the forebay The pond does not include a vegetated filter at the outlet
All stormwater emanating from new impervious surfaces that is generated on -site shall be collected and
directed to the southern side of the site by a system of sheet drainage, grassed swales and storm drainage
pipes
The treatment system will require periodic maintenance Maintenance frequency shall be dictated by pond
depths Pond depths shall be checked by the owner on a quarterly basis When measured depths are less
than 4 50' (for the main pond as well as the forebay), the pond shall be manually dewatered (pump) and
accumulated sediment removed and properly disposed of
Site topography is gently sloping (0 — 5%) with the lowest elevations towards the southwesterly boundary of
the tract Soils are loamy sand/sandy loam
The entire area designated within "Clearing Limits" will be disturbed during initial construction, and will include
grading for parking, swales and storm drainage The proposed stormwater pond shall be used for sediment
storage during construction The perimeter swale shall be used as a temporary diversion to divert runoff to the
pond during construction

Using Surface Area to Drainage Area Ratio Chart for 90% TSS Removal (copy attached) and
assuming 6 foot pond depth
SA/DA = 4.1325 % (interpolated)
Therefore
Surface Area = SA/DA x Drainage Area
13,128 SF say 13,245 SF

c Compute Minimum Pond Dimensions
Assume rectangular shape with 3 1 Length (L) to Width (W) Ratio
Length = 199 34 feet
Width = 66 45 feet
Site conditions, however, dictate irregular shaped pond
Hydr Length =
so, Hydr Width
Actual L/W =
46 R feet
64 3 feet (avg)
3 2 (irregular shape)
3 DETERMINE VOLUME TO BE CONTROLLED FROM 1" STORM
Using Schuler "Simple Method"
Rv = 0 05 + 0 009(I) where I = percent impervious
Rv = 0 710 in/in
Control Volume = Design Rainfall x Rv x Drainage Area
Control Volume = 18,793 CF
4 DETERMINE REQUIRED STORAGE DEPTH
Assume 3 1 side slopes
solving for depth (d) by trial & error
d = 1 34
5 DETERMINE ORIFICE SIZE
say " 19,244 CF
Control Volume must be drawn down over a 2 day - 5 day period
Using orifice equation, solve for Diameter (D) that results in 3-1/2 day period
D=(Q/0026(h)s)s
Where Q = (Control Volume / 3 5 days x 86,400 sec/day)
0 064 cfs
h=d/2
= 0 67
Solving for D

D = 1 73 Use 2:00 "pipe
Actual Drawdown with actual drawdown pipe diameter (using orifice equation)
Q= 0 085 cfs
Draw Down Period = 2 62 days OK, < 5 0
6 SELECT OUTLET STRUCTURE DIAMETER
Size outlet structure such that depth of Q10 flow <1 0 feet
Using Rational Formula (Q=CIA) where
Cimper = 0.8
Cpery = p,
Ccum = 064
110 = 7.17 in/hr
A= 729ac
Q10 = 33 46 cfs
Assuming 1/2 circumference is used as weir and using
Francis Formula (Q=3 33LH' 5) to solve for L such that H = 1 0
L = 10 05 Feet
Min 60 inch diameter outlet structure
Use 60 inch diameter outlet structure
7 DETERMINE Q10 STAGE
Q 10 = 33 46 cfs
Using Francis Formula (Q=3 33LH' 5) solve for H
H10 = 1 18 feet
8 DETERMINE 0100 STAGE (ELEV OF EMERGENCY SPILLWAY)
Using Rational Formula (Q=CIA) where
Ccum = 064
1100 = 8.50 in/hr
A = 7 29 ac
0100 = 3967
Using Francis Formula (Q=3 33LH' 5) solve for H
H 100 = 1 32 feet

9 DETERMINE Q100 STAGE OVER EMERGENCY SPILLWAY (TOP BERM ELEV )
Assume primary spillway blocked (i e , emergency spillway to accommodate Q100)
Emergency spillway shall be a broad crested earthern weir designed to pass 100 year storm
Using broad crested weir equation H = (Q/Cw x L)213
where Q = Q100 39 67 cfs
Cw=30
Length = 24 feet
H = 0 67 feet
