Thank you for your PCN, dated 12/1/2022, for the above referenced project. I have reviewed the information and need
clarification before proceeding with verifying the use of Nationwide Permit (NWP) 29 (https://saw-
reg.usace.army.mil/NWP2021/NWP29.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your application withdrawn and close the file: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) Please clearly label the proposed stream crossing of Ouray Drive on the plansheet entitled "JORDAN LAKE
RAPERIAN BUFFER & WETLAND LAND IMPACTS" (Sheet No. 15);
2) Items regarding the zoomed -in plan view provided with the PCN submittal and labeled "Figure 2":
a. Ensure that the plan view clearly shows the boundaries of the existing stream and wetland as well as the
culvert alignment, headwall locations (if proposed), and any rip rap proposed. This information is
necessary to evaluate whether or not the culvert aligns with the up and downstream stream channel to
avoid indirect impacts of stream bank erosion and sediment loading into the streams;
b. Please correct inconsistencies between this plan view and the PCN. Namely, Section D.3 of the PCN
states that the impact length is 111 linear feet at 3 feet wide, a total stream impact areas of 0.3008 acre.
However the plan view shows a "Channel Impact" of 0.03 acre. This difference is important due to the
compensatory mitigation threshold for stream impacts per NWP 29 Regional Condition B.7 (0.02 acre).
Please correct this discrepancy, ensuring that the stream acreage impact estimate is based on the with
from Ordinary High Water Mark to Ordinary High Water Mark, rather than top -of -bank to top -of -bank.
3) Please provide a profile view of the proposed stream crossing along the proposed culvert. This profile should
show the culvert, any proposed rip rap pad(s), and the existing stream bed. Also, label the proposed slope of the
culvert and clearly note whether or not the rip rap in the stream bed will be keyed into the stream bed (see
below);
Any rip rap placed in the streambed must be keyed in/depressed into the stream bed such that the top of the rip
rap is no higher than the stream bed (NWP 29 Regional Condition B.8), and the profile view should clearly show
that. If above -grade rip rap is proposed on the stream bed due to needed velocity dissipation, clearly describe
this in the PCN and show on the plans; note that this would be considered a permanent impact and count
towards the compensatory mitigation threshold;

4) A wetland impact (Wetland Impact Phase 3) is shown on the plansheet entitled "JORDAN LAKE RAPERIAN
BUFFER & WETLAND LAND IMPACTS" (Sheet No. 15) but is not included in the PCN. Given that the Corps can
only authorize the use of Nationwide Permits for single and complete projects (NWP General Conditions 15, 28,
32), please ensure that all current and future proposed impacts to potential waters of the US (streams,
wetlands, etc.) are included on the plans and PCN, and that the two are consistent;
5) In order to show that the proposed wetland impact (Wetland Impact Phase 3) will not result in reasonably
foreseeable indirect impacts to any of the remainder of Wetland WB-04, please describe measures taken to re-
introduce surface or subsurface hydrology to this wetland at the proposed toe of fill. Typical measures include a
French drain from the seep point/wellpoint to an outlet at the toe of fill and/or low velocity discharge from a
stormwater pipe to the toe of fill. If such changes are practicable, please describe and update the plansheet(s)
accordingly. Unless otherwise justified per the above, the Corps would consider a portion of the remainder of
the wetland downslope of the toe of fill as an indirect impact (see NWP General Conditions "District Engineers
Decision") resulting from a loss of hydrology.
6) It is your responsibility to contact the North Carolina Division of Water Resources (NCDWR) Winston Salem
Regional Office to determine the 401 requirements for this project. Please note that, if an Individual 401 Water
Quality Certification (WQC) is required from NCDWR, the Corps cannot verify the use of any NWP without a valid
401 WQC
Please let me know if you have any questions.
Sincerely,
Dave Bailey
