Thank you for your PCN and attached information, dated 6/19/2020, for the above referenced project. I have reviewed
the information and need clarification before proceeding with verifying the use of Nationwide Permit (NWP) 29
(http://saw-reg.usace.army.mil/NWP2017/2017NWP29.pdf). Please submit the requested information below (via e-mail
is fine) within 30 days of receipt of this Notification, otherwise we may deny verification of the use of the Nationwide
Permit or consider your application withdrawn and close the file:
1) The Corps completed a field verification of the delineation of wetlands and other waters of the US yesterday
with Pilot Environmental. The updated field sketch is attached. Please update the "Stormwater Plan" (Sheet 4 of
17) with the overlay of the verified wetlands and other waters of the US. Although a GPS location of the
approved wetland flags, stream channels, and ponds is acceptable through most of the property, the limits of
Wetland WA/WAA and WD 18-36, and well as Streams ISA and SA in the vicinity of the proposed impact area
must be surveyed by a licensed Land Surveyor. This complete map will allow us the fully evaluate direct and
indirect impacts associated with the proposed project;
2) Regarding the proposed Falcons Trail stream crossing:
a. Given the very small remnant of stream channel that would remain upstream of the proposed following
construction, the Corps will consider the length of stream between the origin of Stream ISA and the
culvert inlet as an indirect loss of stream function and include this length in the calculation of stream
loss. Based on QL2 LiDAR and a georeferenced version of your project plans, this length of stream
channel is approximately 16 linear feet;
b. The proposed culvert slope is very steep (>6%); as such, this culvert would not retain sediment. Further,
the stream bed in this location is rocky with several areas of exposed bedrock. Given the preceding,
there is no environmental benefit to burying the culvert below the stream bed. As such, please confirm
with NCDWR that they are in favor of placing the culvert at grade in this situation. If agreed, please
redesign accordingly and update the PCN and applicable plansheets;
c. Based on item b., embedding the rip rap pad in the stream bed is not practicable. Would it be possible
to only rip rap the banks in this case? If not, update the plans to show the rip rap pad to be placed
at/above grade within the stream channel;
During yesterday's field visit, we observed a rock head cut/"waterfall" approximately 34 in vertical
height near the proposed culvert outlet and rip rap pad, however this feature is not shown on the
profile. Please update the profile drawing accordingly and adjust the proposed crossing to account for
this feature to maintain stability of the stream channel;

3) The "Stormwater Plan" (Sheet 4 of 17), when overlaid on the wetland delineation, indicates via lot lines that the
only access to upland portions of this lot require crossing Wetland WD 18-36. Please explain/show how access
to this lot will be achieved without requiring additional impacts to wetlands. Please note that authorization to
impact this wetland for lot access may be difficult to obtain, given the numerous avoidance and minimization
techniques/methods available to find alternative accesses to this property. Note also that, based on my site visit,
this wetland appears to be a high quality wetland resource
4) Please note that several lots include wetland and/or stream resources within their proposed lot lines, including
Lots 2-17, 19, 20, 25, 27, 28, 32, 33, 41-47 (Lot 47 is bisected by Stream SB).
Please let me know if you have any questions.
Sincerely,
Dave Bailey

The updated map for the above referenced site (SAW-2020-01090) appears to reflect the changes made and discussed
during our site visit on 7/8/2020. 1 will use this map when processing the PJD and/or permit application/request for this
site. Please let me know if you have any questions.
