REQUEST FOR MORE INFORMATION
Dear Mr. Radman:
On March 24, 2008, the Division of Water Quality (DWQ) received your revised application dated March
20, 2008 to impact 0.274 acres of 404/wetland (temporary impact), 295 linear feet of perennial stream,
148 linear feet permanent, perennial stream impact, 661inear feet, temporary, perennial stream impact,
211 linear feet of intermittent stream, and 7,831 square feet of Zone 1 Neuse River basin protected
riparian buffers, and 0.00 square feet of Zone 2 Neuse River basin protected riparian buffers to construct
the residential development at the site. The DWQ has determined that your application was incomplete
and/or provided inaccurate information as discussed below. The DWQ will require additional
information in order to process your application to impact protected wetlands and/or streams on the
subject property. Therefore, unless we receive five copies of the additional information requested below,
your project will be formally returned as incomplete. Please provide the following information so that we
may continue to review your project.
Additional Information Requested:
1. Please resubmit site plans NS-1 and NS-Ion a larger scale, preferably 1 "= 50'. Each BMP and its
outlet structures, and topographic contours through adjacent buffers all the way to the receiving
stream must be shown.
2. For the proposed on-line bypass channels through the buffers that receive flows from the BMPs,
please include ,
a. Their impacts in your PCN, clearly identifying each one, and with larger impact maps
(impacts are allowable),
b. Channels shall not intersect streams perpendicularly, but be angled at approximately 75°
to avoid bank erosion at opposite side of stream.
c. Channel (sizing and lining) design information, with cross sections, discharge velocity
calculations for the 10-year storm (flows the BMPs).

plan view of each impact. Individual impacts must be enumerated on the impact maps by zone
(e.g. zone 1 = 0.2 acres, etc).
4. Please provide detailed impervious area calculations for each drainage area shown on drainage
map NS-7. In particular, please include average lot size, number of lots, street and driveway
dimensions, etc used in estimating the impervious amount in each drainage area.
5. Please include culvert design and its attendant plunge pool velocity dissipater sizing calculations,
and provide cross sections of streams showing culverts and dissipater pads.
6. If Atlas Drive is a thoroughfare that will be taken over in the future by the Department of
Transportation (DOT), please provide a written approval that the locations of the proposed
wetlands DB #9 and DB # 8A & 8B are acceptable - i.e. they meet their safety, vehicle recovery
area and maintenance/right of way setbacks.
Please submit this information within 30 calendar days of the date of this letter. Please contact me in
