Dear Mr. Davis: Onslow County
The Wilmington Regional Office received the Stormwater Management Permit Application for Pirates Cove Townhomes
on August 15, 1997, with final information on January 16, 1998. 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
2H.1000. We are forwarding Permit No. SW8 970834 dated January 26, 1998, for the construction of Pirates Cove
Townhomes.
This permit shall be effective from the date of issuance until January 26, 2008, 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.

G. Size orifice for 2 day drawdown
a) if 2 day draw down is assumed, avg. discharge rate = 39,542/24x60x60x2 = 0.228 cfs
b) maximum orifice size from orifice formula : Q = CA (2gH) to 1/2 power
where A = area of orifice, sf where H = head in ft.
where C = 0.6 = 1.7 ft
where g = gravity acceleration
so: A = (0.228)/(0.6)[202.2][1.7] to 1/2 power = 0.0363 sf
and D = 2 R so R = [A](144)/pi to 1/2 power = 1.29" therefore D = 2.58 inches
Check orifice size by routing orifice at 12 hour intervals to assure drawdown is between
2 and 5 days. Set bottom of orifice at permanent pond elevation, assume ele = 30.0'

Elapsed time 60 hrs:
Approx storage remaining = 7,572-(0.15x12x60x60) =

Conclusion: drawdown exceeds 2 1/2 days and is less than 5 days

H. Size of outlet device, is a 36 inch diameter overflow pipe with a calculated orifice size
of 2.58 inches diameter. Because the drawdown obviously exceeds 2 days while using
an orifice of 2.58 inches, the size shall be set at 2.5 inches diameter
(see detail on plan). The drawdown will exceed 2 1/2 days and be less than 3 days.
Set concrete overflow at elevation 32.0 feet, (6 feet wide, 4 inches minimum depth of
concrete, flume directed into the existing ditch downstream of the pipe).

REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 970834
Pirates Cove Townhomes
Onslow County
The Wilmington Regional Office received previously requested information for the Stormwater
Management Permit Application for Pirates Cove Townhomes on October 9, 1997. A preliminary review
of that information has determined that the application is not complete. The following information is needed
to continue the stormwater review:
1. As discussed in our meeting, please note on the plans that all roof drains must be directed into
the paved areas, or provide swales at the rear of the buildings to pick up this water.
2. The typical building footprints on the plans are neither dimensioned nor noted with the
covered decks, uncovered decks, and concrete areas.
3. Please revise the Pond Section Det4il as follows:
a. Note the width of the vegetated shelf, and the begin and end elevations.
b. Provide a trash rack for the 36" overflow riser.
C. The detail of the orifice in the calculations indicates a 6" 90' elbow, but the riser
detail on the plans indicates only a 2.5" hole in the riser. If .you choose to use the 2.5"
hole in the riser, as currently depicted, then you need to specify a trash rack that can
extend over the orifice.
d. Include the forebay in the section detail.
e. Label the "Water Level Elev. 30" on the detail as the permanent pool.

4. The impervious area breakdown does not add up to the 259,939 square feet you show. All you
did was revise the total. Please indicate the correct breakdown to reach the new total.
5. The orifice size is based on the actual volume provided in the pond between the permanent
pool and the design pool. Since you have set the overflow at 31.75, the storage volume is in
excess of 41,046 cubic feet. Please reevaluate the orifice size using the volume provided.
Please note that this request for additional information is in response to a preliminary review. The
requested information should be received by this Office prior to December 13, 1997, or the application will
be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee.
If you have any questions concerning this matter please feel free to call me at [phone].

Dear Ms. Lewis,
This correspondence is in response to your letter dated September 11, 1997
1. The chloride content was sampled 1/2 mile as the
crow flies, and concentration was found to be 18.7 ppm
(See enclosed letter to Rick Shiver dated Sept. 3, 1997)
2. I've been advised by Charles Rawls, the "accessory use" has been
defined as "playground" and we have only grassed areas, hence no
impervious areas.
3. A signed Pond Maintenance Plan has been attached hereto.
4. Charles Rawls, RLS is the surveyor on this project and he has affirmed
that there are NO 404 wetlands on this tract.
5. We have detailed the cross -sectional areas which were requested, ie, the
bottom, top, 6:1 shelf, 3:1 slopes, 2:1 slopes, forebay, etc.
6. The outlet structure detail is also included herein. The apparatus is a
pipe elbow, 6 inches diameter, field fit and fabricated for installation.
7. The permanent pool dimensions are shown on the plan.
8. The calculations reflect 259,939 square feet total impervious area as
as calculated by Charles Rawls, RLS.
9. The minimum depth of the pond will be 5.0 feet.
10. Calculations for the drawdown are included on another sheet attached hereto.
11. All backslopes above the permanent water level are 3:1 maximum.
12. The runoff from the entrance road has been altered to capture the runoff as
requested.

13. There are no swales (only those in the immediate vicinity of the yard inlet).
14. The pond dimensions are included on the plan as requested.
I regret it took so long to respond to your comments and appreciate the telephone conversations.
Thank you for your attention to this project.
Sincerely,

Subject: ACKNOWLEDGEMENT OF RECEIPT AND
REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 970834
Pirates Cove Townhomes
Onslow County
Dear Mr. McLean:
The Wilmington Regional Office received a Stormwater Management Permit Application for Pirates Cove
Townhomes on August 15, 1997. A preliminary review of that information has determined that the application is not
complete. The following information is needed to continue the stormwater review:
✓ 1. This project drains to SA waters. Please provide the results of a chlorides test taken at a point in the
receiving waters that is 1/2 mile as the crow flies from the proposed discharge point. The sample must
be taken after 3 days without rain. Assuming that the sample comes back at less than 500 ppm, the
remaining items to be addressed follow.
2. What type of pavement does the area labelled "Accessory Use" at the end of cul-de-sac have? Please
remember that any area used for parking or subject to vehicular traffic is considered impervious.
V 3. A signed Operation and Maintenance Plan, enclosed.
J 4. Delineate all wetlands on site, or note on the plans that none exist.
5. Provide pond details on the plans, including a section with the bottom, normal pool, design pool and
top of bank elevations; 6:1 vegetated shelf, forebay, and 3,1. slopes above the permanent pool noted.
6. Provide an outlet structure detail with the orifice size and type of trash rack noted.
7. Provide dimensions for the permanent pool.

8. The calculations use 248,069 square feet in determining the pond size, the application lists 253,148
square feet, and my calculation indicates 255,000 (including "Accessory Use" area). Please check
your calculations and revise accordingly.
9. If you must work backwards to see if the available surface area in the pond will meet the required
surface area, please choose a depth from the chart of either 3.5 or 4, not 3.8.
10. Most engineers calculate both the 2 and 5 day drawdown orifice sizes and choose a readily available
stock size in between such as 1.25", 1.5", 1.75" etc. Specifying a 2.66" orifice seems a little
unnecessary when a stock size of 2.5" would do the job just fine. Additionally, the head used in the
orifice calculation is an average head measured from the design pool elevation to the center line of
the proposed orifice.
11. The road detail indicates cut/fill slopes of 2:1. The regulations require all vegetated slopes to be 3:1
or flatter. Please revise.
12. It appears that runoff from over 9,000 square feet of entrance road is allowed to leave the site
untreated. Please pick up this runoff and get it to the pond.
13. Where are the graded swales that are referred to on the application that pick up runoff? The grading
plan does not indicate any swales.
14. Delineate, label and dimension the permanent pool
Please note that this request for additional information is in response to a preliminary review. The requested
information should be received by this Office prior to October 11, 1997, or the application will be returned as
incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. If
you have any questions concerning this matter please feel free to call me at [phone].

intersection of SR 1737 and NC 24 which is approximately 1/2 mile from the project in
Cartwheel Branch.
The sample was taken by Dan. Fortin (licensed operator) and tested at Beacham Laboratory in
Jacksonville. The chloride level was shown to be 18.7 ppm. If there are any comments or
questions, I will be glad to discuss there with you or one of your staff.
Please respond when you have been able to address this matter.
Sincerely,
IcLean, P.E.

intersection. All other adjacent property in the vicinity is residential or agricultural use.

Soil Conditions:
This property is shown on an enclosed sheet of the Onslow County Soils Map ( USDA ). It is
predominately Onslow Soils ( loamy fine sand ), characterized by nearly level, moderately well
drained soil. Part of the tract under consideration is classified as Rains ( fine sandy loam ). These
areas are nearly level poorly drained soils on uplands.
Development Notes:
The owner intends to clear the site, add fill as required to meet design grades, excavate the
detention pond, construct streets, building pads, and associated site work to effect the drainage
plan.
Application for a driveway connection has been made to the Department of Transportation.
There is a requirement for 60 lineal feet of 18 inch diameter reinforced concrete pipe in the
gutter line at the entrance to the property.
Planned Sedimentation and Erosion Control Practices
1.
2.
3.
4.
5.
Construction Entrance: A typical construction entrance shall be constructed at the
entrance to the property as detailed.
Silt Fence: This measure is planned for the entire perimeter. The contractor shall
exercise caution to ensure proper installation. No site fence is to be installed in ditch
lines or at pipe outlets, etc.
Temporary Sediment Basin: The wet detention basin will be over excavated to provide
for 19,800 cubic yards of storage for temporary sediment.
Yard Inlet Protection: There shall be rock/filter devices installed to ensure silt is
restricted from entry to the pipe system (See plans).
Block and Gravel Inlet Protection: At each catch basin and drop inlet, sediment will be
restricted by the use of block and gravel devices prior to vegetation stabilization at the
site.
File: PiratesCover.S&E

CONSTRUCTION SEQUENCE
1. Obtain Sedimentation and Erosion Control Plan Approval before any other
land disturbing activities begin.
2. Install construction entrance and pipe at SR 1509 (see detail).
3. Begin clearing operations in roadways, remove vegetation, pile and burn debris
if permitted (haul to approved disposal site if burning is prohibited).
4. Install any sediment control measures where practical as construction
progresses. Pay particular attention to silt fences (first measure).
5. Excavate detention pond/sediment basin as detailed, exercising care to store
material for drying in an .area (which is protected by silt fence or swales),
while not allowing sediments into adjacent areas.
6. Grubbing and grading shall be done carefully only if the project is protected so
any sediment runoff stays on site.
7. Install utilities (water, sewer, electrical lines, telephone, cable)
Install protection devices to retain silt from interior of all pipes.
8. Careful coordination is required to install all transmission pipes while other
work may be progressing.
9. Haul additional fill material to site for building pads etc.
10. Fine grade streets, parking areas and building pads.
11. Apply seed, fertilizer and mulch (mulch all slopes of 4:1 or greater).
12. Install marl street base (6" minimum compacted depth of CABC).
13. Install I-2 asphalt paving on streets and parking.
14. Dress all bare areas, remove any remaining root mat etc, and reseed as necessary
to provide vegetative ground cover.
NOTE: Any area brought to final grade shall be seeded or sodded upon
completion.

Stormwater Detention Basin
for Pirates Cove Townhouses
Swansboro, N.C.
Sample Calculations and Assumptions
A. Total site area = 474,501 sf (Charles Rawls & Assoc.)
B. Total built upon surface 248,069 sf " if of
C. Design for 90% TSS removal by detention basin
D. Receiving waters are classified as SA, but less than 5ppt salinity
E. Assumptions and Calculations:
Basin volume required between normal pond elevation & emergency overflow =
474,501 x 1/12 = 39,542 cubic feet
Detention basin surface area (SA) at normal pond elevation = 22,750 (estimated from
Charles Rawls map)
No off site stormwater run-on.
SA/DA % _ (permanent pond surface area/total drainage are to detention basin) x 100
= 22,750/474,501 x 100 = 4.79 use 4.8
% built upon area = (248,069/474,501 x 100 = 52%
Minimum average depth of permanent pool required for detention basin
(by linear interpretation of Driscoll model tables by DWQ) = 3.8'
To sustain minimum average of 3.8', the minimum pool volume must be maintained
greater than 22,750 x 3.8 or 86,450. From above, 39,542 cf of storage must be
provided above the permanent pond elevation.

99,344 cf
= 24.0'
15,972 sf
16,544 cf
106,526 cf
So, by interpolation, the minimum pond depth must be set at 25.77 feet and for
temporary storage for sediment detention, the minimum depth must be set at 24.57 feet.

F. Side slopes above the permanent water level are 3:,
below the permanent level are 2:1
Ground Level Surface Area Volume Total Storage

= 31.0 24,596 sf 23,672 cf 23,672 cf
= 32.0 26,513 sf 25,555 cf 49,226 cf
Therefore by interpolation, the emergency overflow height above the permanent pond
must be set at 31.62 feet.
G. Size orifice for 2 to 5 day drawdown.
a) if 2 day draw down is assumed, average discharge rate = 39,542/1440 x 2 = 0.21 cfs
b) maximum orifice size from orifice formula Q = CA (2gH) to 1/2 power
where A = area of orifice, sf where H = head in ft.
where C = 0.6 = 1.62 ft
where g - gravity acceleration
so: A = (0.211)/(0.6)(2<32,2>x1.62>to 1/2 power = 0.0388 sf
and D = 2 R so R = 44(144)/pi> to 1/2 power = 1.33" therefore D 2.66 inches
Check orifice size by routing orifice at 12 hour intervals to assure drawdown is between
2 and 5 days. Set bottom of orifice at permanent pond elevation, assume ele = 30.0'

Elapsed time 24 hrs:
Approx storage remaining = 29,303-(0.224x1440) = 19,626 cf Approx. H = 1.16' Q 0.201 cfs
Elapsed time 36 hrs:
Approx storage remaining = 19,626-(0.201x1440) = 10,942 cf Approx. H = 0.46, Q= 0.121 cfs
Elapsed time 48 hrs:
Approx storage remaining = 10,942-(0.121x1440) = 5,714 cf Approx. H = 0.241, Q = 0.0917 cfs
Conclusion: drawdown exceeds 2 days and is less than 5 days

H. Size of outlet device, is a 36 inch diameter overflow pipe with orifice of 2.66 inches
diameter. (see calculation of flow on Sed. and Erosion Control Plans)
Set overflow at elevation of 32.0 feet, properly cemented in place as shown on the plan.
Maintenance Guidelines and Schedules
1. Remove all sediment from basin to provide minimum design depth prior to final
basin stabilization.
2. Stabilize detention basin embankments with vegetation within 30 working days of
grade completion.
3. Inspect embankments weekly, for first year. Reseed and fertilize as needed to assure
stabilization.
4. Mow portion of embankment at least annually to control the natural growth of trees.
5. Introduce top water minnows (Gambusia affinis, or commonly called mosquito fish)
to control mosquito breeding in the permanent pond within 30 days of
construction of the basin.
6. Inspect annually and drain the basin to remove accumulated sediments.
7. Inspect monthly during spring and summer seasons for debris that may reduce
hydraulic efficiency or near the overflow apparatus. Remove debris
immediately upon notice.
