Subject Property: Brightleaf at the Park

REQUEST FOR MORE INFORMATION

Dear Mr. Westmoreland:
Natural Resources
William G. Ross, Jr., Secretary
Alan W. Klimek, P.E., Director
DWQ Project # 04-1111
Durham County
On July 7, 2004, the Division of Water Quality (DWQ) received your application dated July 7, 2004 to impact
0.49 acres of wetlands, 0.045 acres pf isolated wetlands, 1,490 linear feet of streams and 222,405 square
feet (ft2) of riparian buffer to construct the proposed Brightleaf at the Park Subdivision. 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, streams and/or buffers on the subject property. Therefore, unless we receive the additional
information requested below, we will have to move toward denial of your application as required by 15A
NCAC 2H .0506 and 26 .0233(8) and will place this project on hold as incomplete until we receive this
additional information. Please provide the following information so that we may continue to review your
project.
Additional Information Requested:
General Comments:
1. Please provide lot layout including footprints of homes, driveways, and other impervious
features in order to assess the percentage of impervious cover at the site. Despite being
below 30%, DWQ may require stormwater control, because of dense concentrations of
development and the potential reduction in filtering capacity of an already impervious
landscape (Triassic Basin) due to proposed stream and wetland impacts.
2. Please provide the following detail in order to better interpret and refer to features and
impacts in your site plan: street names, labels for stream and wetland features, and lot
layout numbers.

3. Please provide 1 "=50' drawings and details for all road crossings including rip rap
dissipater pads and culvert dimensions.
4. Please provide anti-seep collar design and confirmation that these will be used in
all sewer line crossings through wetlands as per Condition 16 of WQC #3374.
5. Please indicate diffuse flow provisions into buffers at all road crossings.
6. Please clearly indicate remaining wetlands and streams on site that will not be impacted
and those to be preserved.
7. There are numerous parallel buffer impacts shown in Zone 1 related to a concurrent
application for a sewer line impacts (DWQ# 04-0954). Please clarify whether these
impacts are intended or are simply mistakes on your plan. Parallel impacts to Zone 1
will not be permitted.
8. everal instances of stormwater devices in Zone 2 of the buffer (Impact 2-2,
8-3, 7-1, 7-2, 2-2, 19-5). Please move these devices out of the buffer.
`,
Minimization:
1. There are numerous instances where this office believes sewer lines could be reconfigured
or consolidated to minimize impacts to streams, wetlands, and buffers. They are as follows:
a. Impact 8-2. Reroute this sewer line to the west around isolated stream and wetlands.
b. Impacts 3-3, 7-3, and 3-4. Consolidate these crossings into one single crossing.
c. Impact 16-1. Move this sewer line to cross at Impact #16-3 (Wetlands Road Crossing).
d. impact 3-6. Realign sewer line to future Northern Durham Pkwy.
e. Impact 3-7. Move sewer line to east to avoid wetland impact.
f. Impacts 3-9, 3-10, 3-11, and 3-12. These sewer lines can be consolidated into one
single crossing.
g. Impact 3-5. Move sewer line out of buffer.
h. Impacts 19-1 and 19-2. Move this sewer line to the west to avoid wetlands and buffers.
i. Impact to SE of Impact 3-10 (not accounted for in PCN). Move sewer line to the east to
avoid isolated stream.
j. Impact 38A-1. Move sewer line northwest out of wetlands.
k. Impact 12-1. Eliminate this sewer line or explain why it is necessary.
I. Impact 11-? (south of Impact 11-2). Move sewer line out of buffer.
2. Additionally there are several impacts associated with road crossings and lot fill that this
office believes to be unnecessary. Please eliminate or minimize these impacts or provide
a justification for them.
a. Impact 11-3. Lots associated with this fill will still be unusable because of the presence
of the intermittent tributary to the west.
b. Impact 3-13. Please provide justification for this crossing or eliminate it.
c. Impact 16-2. Please provide justification for this fill or eliminate it.

d. Impacts 19-3 and 19-4. Consolidate these crossings or eliminate one to reduce the
number of stream crossings in this area.
e. Impact 20-2. Please provide an explanation as to why this crossing is necessary or
eliminate impacts.
f. Impact 3-1. This impact to perennial waters does not appear to be accounted for in
the PCN. Please address this impact.
g. Impact 19-6. Please provide justification for this crossing or eliminate it.
h. Impacts 37-1 and 37-2. Please realign the southeast portion of the residential
development to avoid impacts to wetlands, streams, and buffers. If it is not possible
to realign this area, please move Impact 37-2 (roundabout) out of stream and buffers.
i. Parking area on southeastern edge of site boundary. Move parking lot out of Zone 2
of the buffer.
j. Impacts A-1 and B-1. Please realign Adams St. to avoid impacts to wetlands, streams,
and buffers.
Unexplained items on site plan:
1. Please explain the device that crosses the wetlands north of Impact 3-13.
2. Please explain the device in the stream northwest of Impact A-1 (visible on Sheets 4 and 8).
3. Please explain the device in the buffer north of Impact 19-3
Please respond within three weeks of the date of this letter by sending this information in writing to this
office. If we do not hear from you within three weeks, we will assume that you no longer want to pursue this
project and we will consider the project as withdrawn.
This letter only addresses the application review and does not authorize any impacts to wetlands, waters or
protected buffers. Please be aware that any impacts requested within your application are not authorized (at
this time) by the DWQ. Please call Ms. Deborah Edwards or Mr. John Dorney at 919-733-1786 if you have
any questions regarding or would like to set up a meeting to discuss this matter.
Sincerely,
