Note: The required surface area calculated from the tables is to be provided at the permanent pool elevation.

Footnotes:
When using the Division SAMA tables, the correct SAfDA 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.
z In the 20 coastal counties, the requirement fora vegetative fil ter may be waived ifthe vet 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.
II. REQUIRED ITEMS CHECKLIST

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 night-
- 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.
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 Xdoes not' incorporate pretreatment other than a forebay.
Form SWU-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 Z` .75' feet in the main pond, the sediment shall be'removed.
When the permanent pool depth reads Z11.75- feet in the forebay, the sediment shall be removed.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
5. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through
the emergency drain shall be minimized to the maximum extent practical.

Footnotes:
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.
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. .
II. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section: IS A NCAC 2H .1008.
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached. If the applicant has designated an agent in the Stormwater Management Permit
Application Fom the agent may initial below. If a requirement has not been met, attach justification.
Applica 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.
d. The temporary pool draws down in 2 to 5 days.
e. If.mquired, a 30-foot vegetative filter is provided at the outlet (include non-c-rosive flow
calculations)
The basin Iength to width ratio is greater than 3:1.
The basin side slopes above the permanent pool are no steeper than 3:I.
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 night -
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.
m. A mechanism is specified which will drain the basin for maintenance or an emergency.
III_ WET DETENTION BASIN OPERATION AND MARMNANCE 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 SWU-l02 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 2q•7Sfeet in the main pond, the sediment shall be removed.
When the permanent pool depth reads Z q- ?sfeet in the forebay, the sediment shall be removed.

We received your letter of request for additional information on this project. We have made
revisions on the project and offer the following responses to your comments:
1. No wetlands exist on site and a wetlands map depicting no wetlands exist on the site is
included with this submittal.
2. A vicinity map has been added to the plans.
3. A stakingldimensionin plan has been added to this submittal.
4. The proposed drainage area for pond 43 has been revised so all offsite runoff is routed around
this site.
5. The offsite runoff is routed around this site.
6. Pond sections have been added to the plans.
7. The calculations have been revised.
8. The dewatering device has been revised. The orifice is now protected by an inverted pipe.
9. Calculations have been sealed.
10. Ponds have been revised and dimensioning detail has been added.
11. The surveyor researched this and there is not a tie within 2000 feet of the project. I could not
locate this information to provide on the plans.
12. The project acerage is 46.54 ac.
13. Warren Mitchell has been added as the agent for NCDOT.
14. We have revised the SA/DA ratios.
15. We used the 90% TSS chart and opted not to design the vegetated filter.
16. We revised the pond volumes.
17. We used the recommended guidelines and revised the orifice sizes.
If you have any additional questions or comments, please do not hesitate to call me.
