Good Afternoon David,
Please find the attached and below responses to your request for additional information. Please let me know if you
require more information. Thanks.
USACE Comment 1) Given the relatively steep slope (2.5%) of the proposed culvert, we are concerned that this stream
would be subject to headcutting above the proposed culvert due to the proposed V invert burial. Please confirm with
NCDWR regarding whether or not culvert burial is required/advisable in this situation. If burial of the culvert pipe is not
advised, please redesign accordingly and update the PCN and applicable plansheets;
Applicant Response: See attached updated PCN and impact exhibits.
USACE Comment 2) We have scaled the proposed culvert on the plans provided and determined stream impacts to be
different than those reported in the text of the PCN/plans:
A. Given that the culvert outlet would not occur directly in line with the existing stream channel, a portion
of the stream channel below the culvert would be cut off from direct stream flow. This does not appear to have been
accounted for in the reported permanent loss stream impacts. If a straight line is drawn along the center of the culvert
from the upstream point where the headwall intersects the stream centerline to the point where the straight line
intersects the stream centerline below the culvert (see attached, blue line), the impacts along the centerline of the
stream (see attached, red line) scale to approximately 114 I.f. Please update the PCN (including the mitigation proposal)
and plans accordingly;
Applicant Response: See attached updated PCN and impact exhibits.
USACE Comment 2)
Any additional impacts in the rip rap footprint not covered above would be considered rip rap only, i.e.
permanent impacts but no permanent loss;
Applicant Response: See attached updated PCN and impact exhibits.
USACE Comment 3) Given that the proposed culvert would intersect the downstream portion of the stream channel at a
skew, please provide additional stream bank protection to ensure scour does not occur along the stream bank
downstream of the proposed crossing. Please updated the project plans accordingly, and provide a profile/cross-section
clearly showing the proposed stream bank protection (see attached Profile Example);
Applicant Response: See attached updated PCN and impact exhibits.
USACE Comment 4) The proposed wetland impact includes fill in the top half of a small narrow wetland. Given the small
size of the wetland in question, and the fact that the drainage area for this wetland would be rerouted due to grading in
the upland portion of the site, the Corps would consider the remainder of this wetland as an indirect impact. As such,
the wetland loss due to direct and indirect impacts would include the entirety of Wetland WC, or 640 sq. ft. (0.015 acre).
Applicant Response: See attached updated PCN and impact exhibits.
Sincerely,
Bradley S. Luckey, PWS

The purpose of the proposed project is to provide access and construct Phase 2 of the Cambridge Park residential
subdivision.
3e. Describe the overall project in detail, including the type of equipment to be used:
The overall project consists of the development of Phase 2 of the Cambridge Park residential subdivision. At this time,
Phases I A and 1 B have been constructed and Phase 2 has been fully designed. With the exception of Phase 7, the
remainder of the residential subdivision has been conceptually designed. At this time, Phase 7 has not been
conceptually designed. With the exception of Phase 7, it appears the remainder of residential subdivision can be
developed without future impact to WoUS outside of those proposed in this application. The applicant understands that
additional impacts associated with the remaining phases of the proposed subdivision will be cumulative for purposes of
permitting and mitigation requirements.
Phase 2 of the site consists of developing the site with residential lots, one stormwater retention pond and associated
roads. Access roads and residential lots will result in impact to streams and wetlands. To facilitate development of the
site, clearing and grading the site is necessary. Graders, haulers, excavators and other heavy equipment will be used
during site construction.

The applicant has previously provided information and obtained a NWP 29 Verification from the USACE (SAW-2017-
02329, dated 6.1.18) and a 401 WQC from the NCDEQ-DWR (#20181041 V3, dated 5.21.19) for the permanent impact to
185 linear feet of stream channel (90 linear feet permanent net loss) and temporary impact to 140 linear feet of stream to
construct access and sewer/water infrastructure for Phases IA and IB in the larger Cambridge Park residential
subdivision.
6.
Future Project Plans
6a.
Is this a phased project?
® Yes ❑ No
6b.
If yes, explain.
The applicant obtained USACE NWP Verification and NCDEQ-DWR 401 WQC for the first two Phase of Cambridge Park,
a residential subdivision. Based on conceptual designs, additional impacts to WoUS are not anticipated in the remaining
phases, with the exception of Phase 7 which has not been designed at this time. The applicant is aware that impacts are
cumulative for permitting and mitigation thresholds for potential future impact to WoUS. However, the applicant is not
ready to proceed with Phase 7 of the subdivision or permit potential impacts associated with Phase 7 at this time.
Establishment of a timeline for future phases of development will be dictated by market conditions at that time. The
applicant acknowledges that the current and future development must occur in a manner to avoid and minimize impacts
to WoUS.

associated with road crossing fill, permanently impact 30 linear feet of perennial steam channel associated with keyed in rip -
rap energy dissipater and temporarily impact 20 linear feet of perennial stream channel with the associated pump around. The
proposed culvert has been designed to discharge to the centerline of the stream. To prevent stream bank de -stabilization
immediate) down -gradient of the proposed culvert, the applicant has designed rip -rap rotection along the northern stream
Page 6 of 12
PCN Form — Version 1.3 December 10, 2008 Version
bank immediately down -gradient of the proposed culvert. The applicant requests written waiver of culvert burial requirements
from USACE and NCDWR due to slope being approximately 2.5% and associated concerns with head cutting of the stream
immediately up -gradient above the proposed culvert.
Areas of rip -rap will be keyed into existing grades of beds and banks and would not be considered a net loss requiring
mitigation. Areas of temporary impact will be restored to similar pre -construction conditions.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The road crossing location was selected in an area of stream that is relatively straight with few meanders and will cross as
near to perpendicular as possible given field and design constraints. The applicant has further demonstrated avoidance and
minimization of stream impacts by proposing to construct approximately 5.5 feet tall culvert head/end walls. Furthermore, the
Applicant has designed rip -rap stabilization measures to be keyed into existing grades of stream bed and banks, thus reducing
the net loss of stream.
There are approximately 9,020 linear feet of stream channel and 0.22 acres of wetlands located on the site. Phase 2 has
been designed to avoid the remaining 8,896 linear feet of stream channel and 0.13 acres of wetlands.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The clearing limits will be staked and silt fence will be used. A Temporary coffer dam will be installed up -gradient of the
proposed road crossing. During construction, water will be pumped around the construction footprint. Appropriate stream
bank protection will be provided in the channel during construction and all excess excavated material will be immediately
removed from the stream bank crossing area. Upon installation of the culvert, the temporary sand bag coffer dams will be
removed and flow will be diverted through the culvert. Disturbed banks will be restored to similar pre -construction conditions,
matted and seeded/live staked.

5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or
❑ Yes ® No
habitat?

❑ Yes ® No
impacts?
❑ Raleigh
5c. If yes, indicate the USFWS Field Office you have contacted.
❑ Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
The USFWS List of Federally Protected Species, dated 6.27.18, identifies the Cape Fear Shiner as being listed within
certain river basins in southern Alamance County. The site is centrally located in Alamance County. Therefore, we have
made a determination of no effect for Cape Fear Shiner. Other federally protected species are not identified in Alamance
County.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat?
❑ Yes ® No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
Based on our knowledge of the site, the site is not located in or near an area designated as essential fish habitat. Best
management practices and the use of temporary sediment and erosion control devices will prevent sediment from entering
down -gradient waterbodies which may contain fish.
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
