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.
Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, snow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
Remove accumulated sediment from the wet detention basin system semi-annually or when depth is

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 31' feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3 .aY feet in the forebay, the sediment shall be removed.

Footnotes:
t when using the Division SAIDA tables, the correct SAIDA ratio for permanent pool sizing should be computed based upon the
actual impervious % and perrnanent pool depth. Linear interpolation should be employed to detemmne 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 BNIP manual provides design tables for both 35%TSS removal and 90%TSS removal

RE: Stormwater Management Permit Application — Tanglewood Lake
Apartments; Stormwater Permit SW7070712
KHA No.: 116039007
Dear Mr. Moore:
Suite 300
501 Independence Parkway
Chesapeake, Virginia
23320
Please find attached two (2) sets of revised construction plans for the above referenced
project for review and approval.
Also enclosed for your review are the following:
- 2 copies of the Project Narrative and Calculations Package
- 1 copy of the Subsurface Exploration and Geotechnical Engineering report
- 1 copy of the revised Stormwater Management Permit Application and
corresponding Wet Detention Basin supplements
Below are our responses to the comments in your letter dated 9/11/07:
1. A sketch of the entire development showing phases one and two has been
included with this submittal. The 60 acre borrow pit'is off -site but is adjacent to
the southern boundary of the property. The borrow pit outfalls into a ditch that
will run along the proposed Centre Green road. That ditch will eventually outfall
into Knobbs Creek, a tributary of the Pasquotank River. The master stormwater
plan for the Tanglewood Development, completed by Bob Farris of CE
Solutions, details how all the off -site drainage is handled, of which our site is a
small portion. This document has already been approved by DWQ and should be
on file.
2. The three, on -site drainage basins are shown in the plans. The off -site drainage
basin (the 60 acre borrow pit) has been designed to handle stormwater quantity
for the above mentioned site and surrounding sites. The stormwater master plan,
completed by Bob Farris of CE Solutions, for the entire Tanglewood
development of which the borrow pit is a part of should be on the file at DWQ.
3. Included in this submittal is the geotechnical report completed by McCallum
Testing Laboratories, Inc. It is their opinion that when the pumping of the
adjacent 60 acre borrow pit is ceased the groundwater will return to a level of 6'-
8' below the existing grade. The pumping of the borrow pit should have already

ceased as a condition of closing on the property was to stop all mining operations
on the adjacent borrow pit. For the majority of the site that will place the
groundwater approximately at an elevation of 7.0. The permanent pool elevation
of the adjacent borrow pit is set to be 8.0. Therefore, due to hydraulic grade line
of our outfalls into the borrow pit we set our permanent pool elevations to 8.5 for
pond one and 9.0 for ponds two and three.
4. All pipes outfalling into the wet ponds have been shown with flared end sections
and rip rap for outfall protection. The inverts and rip rap quantities are shown in
the drainage descriptions on the grading sheets. All catch basins are shown in the
Erosion and Sediment Control plans to include inlet protection.
5. A vegetation plan and detail sheet for the wet pond perimeter shelves for all three
ponds has been provided in the plan set.
6. The ponds have been redesigned to incorporate the requested changes to the
vegetated perimeter shelf.
7. The trash rack shown on the outlet structure will have a hinged, lockable access
door for ponds two and three for access due to the weight of the trash rack
exceeding 75 pounds. Trash racks that weigh less than 75 ponds can be removed
for access/maintenance to the outfall structure.
8. During the initial construction phase of the project, the ponds will be used as
sediment basins. That is the reason for labeling the ponds sediment basins in the
erosion and sediment control sheets. For all other sheets, they are labeled as
ponds.
9. Pond cross sections are shown on sheet CG-104 and the ponds have been
dimensioned in the layout plans.
10. Narrative, plans, and details have been revised to reflect changes.
If you have any questions or need additional information to complete your review, please
contact me at 548-7300. Thank you.
