I When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non
standard table entries.
2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
H. REQUIRED ITEMS CHECKLIST

c. The temporary pool controls runoff from the design storm event.
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.
It. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
Vegetative cover above the permanent pool elevation is specified.
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.
I. 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.
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.does not incorporate a vegetated filter at the outlet.
This system (check one) 0 does$ does not incorporate pretreatment other than a forebay.
Form S W U-102 Rev 3.99 Page 2 of 4
Maintenance activities shall be performed as follows:
1. 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 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 3.75 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 2.25 feet in the forebay, the sediment shall be removed.

My only concern with this application is the wetlands statement. Is the
owner qualified to make the determination that no wetlands exist, or
does he have some documentation? Has anyone from DWQ or the Corps or a
private firm done a delineation?
The call on the presence or absence of wetlands should be made only by a
person with the right background and experience to know what is and
isn't a wetland. This project's proximity to "Sam Varnams Branch" raises
a concern for the potential presence of wetlands.

I do need revised calculations since I can't approve a design that is deficient,
albeit a small amount.
You don't need to move the contours, but please revise the permanent pool
dimensions so that sufficient surface area will be provided.

I Linda:
I have looked at the calculations, and if I round to the nearest loth as you
request, my permanent pool contour will need to be offset by 0.25 feet to
gain the 100 square feet, which will in turn offset each proposed contour
0.25 feet. Do you need revised calculations and a revised grading plan to
proceed?

One more thing- the percent impervious comes out at 70.3%. You used 70%
to figure the SA/DA ratio and Rv factor, which is causing a slight
deficiency (about 100 square feet) in the surface area. Can you tweak
the design a little so that there is no deficiency?

Pike Electric, Inc.
Mr. Gene Walden, Assistant Vice President
P.O. Box 868
Mt Airy NC 27030
Dear Mr. Walden:
This office has received a soil erosion and sedimentation control plan for the project listed below which was
submitted as required by the North Carolina Sedimentation Pollution Control Act INCGS 113A-57(4)).
Please be advised that this Act requires that all persons disturbing an area of one or more acres of land must
obtain approval of a soil erosion control plan prior to the commencement of said land disturbing activity (NCGS 113A-
54(d)(4)). The act further states that this plan must be filed a minimum of 30 days prior to the activity and the
approving authority must approve or disapprove the submitted plan within 30 days of receipt. Failure of the approving
authority to approve or disapprove the submitted plan within the 30 day period will be deemed approval of the plan.
Commencement or continuation of a land -disturbing activity under the jurisdiction of this Act prior to the approval of
an erosion and sediment control plan is a violation of the Act.
A copy of any erosion and sediment control plan which could involve the utilization of ditches for the purpose
of dewatering or lowering the water table is forwarded by this office to the Division of Water Quality (DWQ). It is
suggested that you contact the Division of Water Quality at (910) 395-3900 if the ditches shown on your plan will
lower the water table.
The approval of an erosion and sediment control plan is conditioned on the applicant's compliance with Federal
and State water quality laws, regulations and rules.
If you have questions, please do not hesitate to contact this office. Your cooperation in this matter is
appreciated and we look forward to working with you on this project.

PROJECT NARRATIVE
Pike Electric is proposing to develop property on US 17, approximately 1.75 miles south of NC
211. The property has an existing residence and two existing storage buildings. According to the
Brunswick County tax records, the existing residence was constructed in 1967.
Pike Electric proposes the addition of a gravel area for parking and the storage of heavy equipment.
Stormwater will be directed to a proposed on -site wet detention basin that is designed to treat the
first one -inch of runoff.
The total area of disturbance for the project is 4.8 acres. Temporary silt fencing and a construction
entrance should be sufficient to prevent any significant amounts of sediment from leaving the site.
These measures shall be inspected regularly, and the accumulated sediment removed to prevent the
conveyance of sediment to any off -site areas.
The primary permanent erosion control measures that will remain after the temporary measures are
removed will be permanent grassing and gravel.
