Good Afternoon Jeff,
I started drafting the sw permit and tried to pull together all the pieces needed to make the sw application package
complete. With the info on hand, I can finish the draft; however, we need some minor tweaking to make the package
complete. Please provide the following info/explanations; or call me if you have questions:
1) Need to complete supplement sheets for all (3) ponds with revised numbers, along with O&M signed by William
Stovall. (These forms were provided in October 2009; but the # s changed)
2) Plan sheet 7 indicates seeding for all ponds with trees on perimeter; plan sheet 12 provides a vegetation plan for
Pond 3, which is much different from veg plan shown on Sheet 7. Let's discuss.
3) Stormwater bypass water from Pond 1; need calculations/discussion to verify non -erosive velocity/needs
downstream protection ?
4) Your cals show that Pond 2 does not meet minimum surface area requirements; it appears to be close. Since
regarding was involved, I thought we discussed enlarging pond to meet min. surface area ?
5) Sheet 12, veg plan should speak to fertilizer/lime requirements.
I have the permit dated for 4/15. Can we turn all this around that quickly ? In case you miss me at the office, call me on
my personal cell.

Stonnwater Revisions Submittal SW7091009 ti
Dear Mr. Moore,
This submittal is to update you and NCDENR about a revision we have done to Pond 3. Due to
prior overflows in the storm drain system draining to Pond 3, we have run some models on trying to
case the potential for more overflowing. From these models we have determined that lowering
Pond 3 one foot greatly helps the situation.
Therefore Pond 3 has been lowered by 1 foot and now has a normal pool elevation of 22' FMSL.
Attached in this subtnittal is a set of updated full size plans, updated Pond 3 calculations, and 2
copies of the revised pages 1 and 2 of Pond 3's Wet Detention Basin Supplement and page 3 of
Pond 3's Wet Detention Basin O&NI Agreement.
If you should have any questions with respect to this information, please do not hesitate to contact
me.
Sincerely,

Footnotes:
When using the Division SAIDA tables, the correct SAIDA 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 nonstandard 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. i
11. REQUIRED ITEMS CHECKLIST

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) _does X does not incorporate a vegetated filter at the outlet.
This system (check one) does X does not incorporate pretreatment other than a forebay.
Form SWU-102 Rev 3.99 Page 2 of

Maintenance activities shall be performed as follows:
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 3.0 feet in the forebay, the sediment shall be removed.

computed based upon the actual impervious % and permanent pool depth. Linear interpolation should be
employed to determine the correct value for nonstandard table entries.
x 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. i
11. REQUIRED ITEMS CHECKLIST

Maintenance activities shall be performed as follows:
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, 3.37 feet in the main pond, the sediment shall be removed.
i
When the permanent pool depth reads' 3.37 feet in the forebay, the sediment shall be removed.

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record ion this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public; and the removal efficiency of the BMP.
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):
❑ does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
