Dear Mr. Koenig:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for Huntington Park at Williamsburg Plantation on March 21, 2005. Staff review of
the plans and specifications has determined that the project, as proposed, will comply with the
Stormwater Regulations set forth in Title 15A NCAC 21-1.1000. We are forwarding Permit No.
SW8 040733, dated April 4, 2005, for the construction of the project, Huntington Park at
Williamsburg Plantation.
This permit shall be effective from the date of issuance until April 4, 2015, 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 150B 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.

without the express written consent of the State of North Carolina, Division
of Water Quality.
e. Alteration of the drainage as shown on the approved plans may not take
place without the concurrence of the Division of Water Quality.
f. The maximum built-upon area per lot is 3,480 square feet. This allotted
amount includes any built-upon area constructed within the lot property
boundaries, and that portion of the right-of-way between the front lot line
and the edge of the pavement. Built upon area includes, but is not limited
to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and
parking areas, but does not include raised, open wood decking, or the
water surface of swimming pools.
g. Lots within CAMA's Area of Environmental Concern may be subject to a
reduction in their allowable built-upon area due to CAMA regulations.
h. All runoff on the lot must drain into the permitted system. This may be
accomplished through providing roof drain gutters which drain to the
street, grading the lot to drain toward the street, or grading perimeter
swales and directing them into the pond or street. Lots that will naturally
drain into the system are not required to provide these measures.
i. Built-upon area in excess of the permitted amount will require a permit
modification.
j. Each lot within the subdivision whose ownership is not retained by the
permittee, must submit a separate Offsite Stormwater Management Permit
application package to the Division of Water Quality and receive a permit

Maintenance activities shall be performed as follows:
I. 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 wash 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 aft 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 4.5 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3.75 feet in the forebay, the sediment shall be removed.

Application Form, the agent may initial below. If a requirement has not been met, attach justification.
Applicants Initials
a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
b. The forebay volume is approximately equal to 20% of the basin volume.
c. The temporary pool controls runoff from the design storm event.
DfIll d. The temporary pool draws down in 2 to 5 days.
e. If required, a 30-foot vegetative filter is provided at the outlet (include non-erosive flow
calculations)
f. The basin length to width ratio is greater than 3:1.
g. The basin side slopes above the permanent pool are no steeper than 3:1.
h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
l� i. Vegetative cover above the permanent pool elevation is specified.
I. A trash rack or similar device is provided for both the overflow and orifice.
k. A recorded drainage easement is provided for each basin including access to nearest right-
of-way.
1. If the basin is used for sediment and erosion control during construction, clean out of the
basin is specified prior to use as a wet detention basin.
D m. A mechanism is specified which will drain the basin for maintenance or an emergency.
III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the
vegetated filter if one is provided.
This system (check one) 0 does° d es not incorporate a vegetated filter at the outlet.
This system (check one) 0 does O roes not incorporate pretreatment other than a forebay.
Form SW U-102 Rev 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
I. 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 clays 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.).
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 4.5 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3.75 feet in the forebay, the sediment shall be removed.

Stormwater Treatment &
Erosion Control Narrative
Huntington Park — Section 1
Mr. John Koenig proposes to construct an eighty seven (87) lot residential subdivision on a
36.04 acre tract located in the Williamsburg Plantation Development in Jacksonville, N.C..
The site is currently undeveloped (wooded).
The project area is tributary to New River(C:NSW) in the White Oak Basin. The proposed
development activities are low density (BUA=18.5%) however,-_development of.the project
(DA 1.)-is considered-6 pocket of high density_(BUA::=33:2%). The attached Stormwater Plan
includes a wet treatment pond to provide the required treatment.
The detention pond is sized to accommodate the proposed subdivision only and future
construction which may occur on the undeveloped tract to the east and the proposed road
right-of-way to the north will necessitate additional treatment facilities (pond enlargement).
The basin is sized to accommodate 583,393 square feet of impervious area, allocated as
follows:

The Project consists of a 36.0 Ac subdivision and an 11.3 Ac right of way for Western Blvd. The treatment facilities,
however, are sized to accomodate approximately 25.3 Ac of of site drainage.
2.COMPUTE POND AREA REQUIRED
a. Compute Percent Impervious:
Impervious Areas: Existing Proposed Total
On-Site Buildings 295,800 SF
On-Site Streets 183,996 SF
On-Site Parking 0 SF
On-Site Sidewalks 41,765 SF

FUTURE(unspecified) BiN I 0 SF
Total 12,586 570,807 583,393 SF
Total Area Drainage to Pond: SF
Percent Impervious = 0.185 or 18.5 %
b. Compute Pond Surface Area
Using Surface Area to Drainage Area Ratio Chart for 90%TSS Removal (copy attached)and
assuming 11111M foot pond depth:
SAIDA= % (interpolated)
Therefore:
Surface Area = SAIDA x Drainage Area

34,039 SF say __.... SF
c. Compute Minimum Pond Dimensions
Assume rectangular shape with 3:1 Length (L)to Width (W) Ratio:
Length = 323.58 feet
Width = 107.86 feet
Site conditions, however, dictate irregular shaped pond:
Hydr. Length= 1111MMfeet
so, Hydr. Width 62.3 feet(avg)
Actual L/W= 9.0 (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 = 0.216 inlin
Control Volume= Design Rainfall x Rv x Drainage Area
Control Volume= 56,924 CF say CF
4. DETERMINE REQUIRED STORAGE DEPTH
Assume: 3:1 side slopes
solving for depth (d) by trial &error:
d = 1.88
S. DETERMINE ORIFICE SIZE
Control Volume must be drawn down over a 2 day-5 day period.
Using orifice equation, solve for Diameter (D)that results in 3-112 day period:
D = (Q 10.026(h)5).5
Where: Q = (Control Volume 13.5 days x 86,400 sec/day)
0.238 cis
h = d12
= 0.94

Solving for D:
D = 3.07 Use "pipe
Actual Drawdown with actual drawdown pipe diameter (using orifice equation):
Q= 0.227 cfs
Draw Down Period = 3.67 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=
Cpery=
Ccum= 0.35
110 = in/hr
A= 72.56 ac
Q10 = 165.07 cfs
Assuming 1/2 circumference is used as weir and using
Francis Formula (0=3.331-1-11'6) to solve for L such that H = 1.0:
L= 49.57 Feet
Use 60 inch diameter outlet structure
7. DETERMINE Q10 STAGE
Q10= 165.07 cfs
Using Francis Formula (Q=3.33LH"6) solve for H:
H10 = 3.42 feet
8. DETERMINE Q100 STAGE(ELEV. OF EMERGENCY SPILLWAY)
Using Rational Formula (Q=CIA)where:
Ccum= 0.35
1100= irdhr
A= 72.56 ac
Q100= 215.86
Using Francis Formula (Q=3.33LH''6) solve for H:

1-1100= 4.08 feet
9. DETERMINE 0100 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 215.86 cfs
Cw=3.0
Length = feet
H = 0.80 feet
10. FOREBAY SIZING
Compute Actual Pond Volumes(using average end method):
Avg Incr. Incr. Cum.
Main Bay Volume : Elevation Area (SF) Area SF Depth fFT Vol (CF) Vol (CF)
