All,
Thank you for your response to our request for additional email. Upon review of the submitted information the
following items are unresolved and/or require clarification before proceeding with verifying the use of Nationwide
Permits (NWPs) 14 (https://saw-reg.usace.army.mil/NWP2021/NWP-14.pdf) and 39 (https://saw-
reg.usace.army.mil/NWP2021/NWP39.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 NWPs or consider your
applications withdrawn and close the files:
1) Based on the information submitted the Corps will evaluate impacts to potential waters of the US proposed
under both PCNs as cumulative for one single and complete project, pertaining to NWP and compensatory
mitigation thresholds (per NWP General Condition 28).
2) Thank you for the information submitted in response to item 2) from our 4/7/2022 request for additional
information. The data resolved our concerns with this item.
3) Additional information was not provided to justify the Gallimore Dairy Road Extension as a transportation
project with independent utility, as requested in items 1)b. or c. of our 4/7/2022 request for additional
information. As such, if the primary purpose of Phase A of the Gallimore Dairy Road Extension is to provide
access to Project PNK-High Point, could additional avoidance and minimization of impacts to potential waters of
the US (per NWP General Conditions 23.(a)) be achieved by accessing the proposed PNK-High Point
development site via Joe Drive instead of the proposed Phase A of the Gallimore Dairy Road Extension? If so,
please re -design the project accordingly. If such design is not practicable (available and capable of being done
after taking into consideration cost, existing technology, and logistics in light of overall project purposes), please
provide specific justification.
4) Thank you for the additional information provided pertaining to the proposed bottomless culvert structure. The
information provided satisfies item 3)a. from our 4/7/2022 request for additional information. The information
also indicates that the structure would be tied to bedrock within 5 vertical feet of the soil surface, although it
remains uncertain that the City of High Point would accept the proposed design. Based on our review of the
information provided, proposed permanent loss of stream for the single and complete project is 0.0198 acre
(158 linear feet), whereas the amount of stream proposed under the bottomless culvert is approximately 0.01
acre (135 linear feet). As stated in our request for additional information, based on our District's considerable
experience with these structures, the shading that will occur under the proposed bottomless culvert (^'4-7 foot
height within the ^'145-foot long structure) will lead to the die -off of woody vegetation which provides the
structure that keeps the stream banks intact. Erosion of stream banks then occurs leading to sediment loading in
the stream, over -widening of the channel, and reductions in habitat heterogeneity. Such reductions in stream
function are predictable, and therefore the District reviews these activities as indirect impacts per the NWP
General Conditions District Engineer's Decision part 2. Given that such reduction in function to 0.01 acre (135
1

linear feet) of stream channel is anticipated as indirect impacts, and considering that the proposed permanent
loss impacts to streams associated with the project (0.0198 acre [158 linear feet]) are only slightly below the
compensatory mitigation threshold typified in NWP 39/14 Regional Condition C.7, compensatory mitigation for
these cumulative impacts is warranted to ensure that the cumulative adverse environmental effects associated
with this project are no more than minimal.
You correctly note that the proposed bottomless culvert would not result in a complete loss of aquatic
habitat/function, and does not eliminate all habitat/function or aquatic passage compared to a traditional
culvert with bottom. However, as stated above, reductions in these functions are predictable and therefore
justify a compensatory mitigation requirement, understandably at a reduced mitigation -to -impact ratio at least
for the indirect impacts. Whereas a compensatory mitigation ratio of 2:1 is typically required for permanent loss
impacts, a reduced ratio of 1:1 is typically required for reductions (though not a loss) of aquatic function. As an
example, NCDOT, the entity primarily installing bottomless culverts in North Carolina does so rarely, and when
they do typically provide compensatory mitigation at a 1:1 ratio.
As stated in our request for additional information, an evaluation of stream function (i.e. NCSAM) could be
provided in an attempt to propose compensatory mitigation ratios different than those listed above for both
permanent loss and indirect impacts.
5) Information provided in your response do not adequately address item 5 from our 4/7/2022 request for
additional information. Information we previously provided pertaining to the High Point North Industrial Center
clearly shows that there are future plans for development within this area. These concerns are more relevant
given the absence of justification of the Gallimore Dairy Road Extension as a single and complete project. Unless
the currently proposed project can be justified as having independent utility from the High Point North Industrial
Center, information is needed to justify that the reasonably foreseeable impacts associated with full buildout of
the High Point North Industrial Center would not exceed NWP thresholds.
Please note that responses to the questions above may prompt additional information requests to allow full evaluation
of the proposed project(s), and let me know if you have any questions.
Sincerely,

Subject: [URL Verdict: Neutral][Non-DoD Source] RE: Request for Additional Information for Gallimore Dairy Road
Extension-DWR#20220379 and Project Elixir (350 South)-DWR#20210816- Guilford Co
Good Tuesday Afternoon David/Sue,
I hope you both are well. Please find the attached updated PCNs for the Gallimore Diary Road extension and Project
PNK-High Point and below applicant's response to request for information and comments. Additionally, please note that
Project Elixir name has been changed to Project PNK-High Point. If you require additional information to process the
requests, then please let me know. Thanks and have a great day.
NCDWR RFI 1) Please provide a drawing/plan sheet that shows both Gallimore Dairy Road Extension (in it's entirety)
and Project Elixir and all jurisdictional features to assist the Division with evaluating Avoidance and Minimization for
both projects.
Applicant Response: See Attached Overall Impacts Map, Exhibit 1.0, Gallimore Dairy Road PCN
NCDWR RFI 2) Notwithstanding the responses to item 1 below regarding Gallimore Dairy Road extension:
a. If this roadway is determined to be a public thoroughfare maintained by the City of High Point then we
strongly recommend that the City be a co -applicant for the 401.
b. Depending on the further evaluation of the roadway, the proposed Randleman Buffer impacts may
require Division review and approval.
c. Please clarify who/what entity is providing assurances that future crossings will be constructed as
spanning structures.
d. If the City of High Point is to assume responsibility of the proposed roadway, please provide
documentation that they will allow the proposed spanning structure as it does not appear to comply
with local NCDOT recommendations/requirements.
e. Please clearly show the proposed limits of Phase 1 of Gallimore Dairy Rd extension on the plan sheets.
f. Please provide a detailed stormwater management plan and/or diffuse flow plan for the entirety of
Gallimore Dairy Rd Extension and ensure that the proposed plan is in compliance with the Randleman
Buffer Rules.
Applicant Response: As noted within attached PCNs, the purpose of Phase A of the extension of Gallimore Dairy Road is
to provide access and water/sewer services to the PNK-High Point project. As proposed, the applicant of the Gallimore
Diary Road extension would relinquish maintenance of Gallimore Diary Road extension to the City of High Point
following construction of the Gallimore Dairy Road extension. The proposed Phase A of the extension of Gallimore Diary
Road has been designed to be in compliance with the City of High Point, NCDOT and the Randleman Lake stormwater
and riparian buffer regulations. Requests for review and approval of site plan engineering and stormwater management
requirements has been submitted to the City of High Point for their review and approval.
NCDWR RFI 3) Notwithstanding the responses to item 1 below regarding Project Elixir:
A Please provide information regarding the location of utilities being provided to the site. Will any utility
corridors require additional jurisdictional impacts?
B While the Division recognizes the parking requirements of the applicant, and safe ingress/egress for
large vehicles, it is unclear that the current roadway alignment and parking areas provide for the
maximum Avoidance and Minimization within the site. For example, could employee parking be
reconfigured in a more North/South alignment allowing for the western access road to be moved west
and south and impact less of the stream and buffer at this location?
C It is unclear from the application documentation that the project is in compliance with the City of High
Point's Ordinance requirements regarding the Randleman Buffer Rules. As the Division is unable to issue a
401 Certification that may not be in compliance with the local ordinances related to the Randleman Buffer
3

Rules, please provide a Buffer Authorization (or other form of approval) from the City of High Point or
provide further information/documentation of the City's review process.
Applicant Response: See Attached Overall Impacts Map, Exhibit 1.0, Gallimore Dairy Road PCN and updated PCNs. The
proposed project PNK-High Point is being accessed from Phase A of the Gallimore Diary Road extension (SAW-2014-
02098). The proposed PNK High Point project will connect to exiting sanitary sewer from the southwestern portion of
the site and existing water services from Sandy Ridge Road. An aerial sewer crossing that does not impact waters is
proposed on the western portion of the site. Other or future impacts to waters as a result of the proposed project are
not anticipated. Please see attached page 16, Impact Exhibits, Project PNK-High Point PCN. The proposed riparian
buffer impact and associated stream impact has been designed as a road crossing, whereas up and down -gradient
grading impacts from the proposed access road at 2:1 slope result in the temporary and permanent impact to the
proposed stream buffer as proposed within this application, regardless of overlap of grading or final conditions within
the riparian buffer from parking and proposed building impervious surfaces. Therefore, the proposed crossing is an
allowable use within the Randleman Buffer table of uses. The applicant is in the process of submitting a Randleman Lake
Riparian Buffer No Practical Alternative Letter to the City of High Point for review and approval.
NCWRC Comment 1) We recommend further minimizing impacts to streams. As Sue mentioned, it seems that the
parking layout could be tweaked to reduce impacts.
NCWRC Comment 2) The applicant should consider integrating some Low Impact Development techniques, such as
swales instead of curb and gutter and bioretention cells in parking lot medians
(https://www.uni-groupusa.org/PDF/NC LID Guidebook.pdf) could reduce the size of the
stormwater BMP.
NCWRC Comment 3) Sediment and erosion control measures should be installed prior to any land -disturbing
activity. Incorporate the following elements into erosion and sediment control plans: minimize
clearing and grading, protect waterways, phase construction for larger construction sites (>25
acres), stabilize soils as rapidly as possible (<2 weeks), protect steep slopes, establish
appropriate perimeter controls, employ advanced settling devices, implement a certified
contractors program, and regularly inspect erosion control measures. Excessive silt and
sediment loads can have detrimental effects on aquatic resources including destruction of
spawning habitat, suffocation of eggs, and clogging of gills.
NCWRC Comment 4) Erosion control matting made of plastic mesh or twine should not be used within the project
area, including upland areas, because it can entrap and kill wildlife. The use of biodegradable
and wildlife -friendly sediment and erosion control devices is strongly recommended. Silt
fencing, fiber rolls and/or other products should have loose -weave netting that is made of
natural fiber materials with movable joints between the vertical and horizontal twines. Silt
fencing that has been reinforced with plastic or metal mesh should be avoided as it impedes the
movement of terrestrial wildlife species.
NCWRC Comment 5) Also, non-native plants should not be used for seeding disturbed areas. Specifically, avoid using
Bermudagrass, redtop, tall fescue, and lespedeza, which are invasive and/or non-native. A list of
alternatives to non-native species has been attached. Alternatively, use a grain, such as oats,
wheat, or rye for temporary cover and native seed mixes for permeant seeding. We recommend
planting native, wildflower seed mixes that will create pollinator habitat and/or and plant native
trees and shrubs for landscaping rather than using turf grass. Using native plants will also
reduce costs and time for maintenance of landscaping.
NCWRC Comment 6) Avoid tree clearing activities during the maternity roosting season for bats (May 15 — August 15)
because of the decline in populations of several tree -roosting bat species.
NCWRC Comment 7) We recommend not clearing the entire site, but rather maintaining the maximum amount of
native vegetation as possible. We suggest having the site logged instead of burning the cleared trees.
Applicants Response: The applicants acknowledge recommendations and comments from NCWRC and will incorporate
these recommendations and comments into construction and maintenance of the proposed projects whereas practical
and possible.

USACE RFI 1) The information provided does not fully justify that the proposed Gallimore Diary Road Extension is a
project with independent utility from Project Elixir (350 South). Please provide the following to enable our continued
evaluation:
a. What municipality/entity will assume responsibility and maintenance of this transportation facility into
perpetuity? Please provide any supporting documentation;
b. Provide documentation to justify that this road extension is part of a thoroughfare or other
transportation plan to show purpose and need other than to facilitate access to Project Elixir (350 South)
and future portions of the High Point North Industrial Center;
c. Provide traffic data/analysis to justify the Gallimore Dairy Road Extension as a transportation project
with independent utility, absent of future traffic needs for Project Elixir (350 South) and future portions
of the High Point North Industrial Center;
d. Design of the first crossing only, which does not allow evaluation of all potential direct and indirect
impacts required to complete the proposed road extension to Adkins Road (i.e. not logical termini), is
insufficient for the evaluation of the proposed road extension. Please provide plan and cross section
drawings of the remaining crossings;
e. In order to justify width of the proposed roadway and show avoidance and minimization to the
maximum extent practicable per NWP General Condition 23a, please provide the roadway cross section
showing the number and width of travel lanes and shoulder widths, and a description of how that
compares to the existing portion of Gallimore Dairy Road just east of the existing intersection of Sandy
Ridge Road and Gallimore Dairy Road;
f. Absent Project Elixir (350 South), would an alignment of Gallimore Dairy Road be available/viable to
avoid at least one stream crossing, such as aligning the route south of the origins of Streams MSB/BSA
and thereby crossing Stream MSA downstream of its confluence with Stream MSC?
Applicant Response: See attached updated PCNs. The proposed project PNK-High Point is being accessed from Phase A
of the Gallimore Diary Road extension (SAW-2014-02098). The proposed PNK High Point will connect to exiting sanitary
sewer service from the southwestern portion of the site and existing water services along Sandy Ridge Road.
USACE RFI 2)
The Gallimore Dairy Road Extension alignment intersects with Adkins Road just west of a topographic
drainage that occurs outside of the PJD Review Area for Project Elixir (350 South) and does not appear
to be covered by the additional evaluation area you provided in the PCN. Within the proposed
alignment, has this drainage been evaluated for the presence of potential waters of the US, including
wetlands? Please provide documentation accordingly.
Applicant Response: Pilot personnel conducted a stream/wetland delineation for an approximate 5.10-acre tract,
located along Adkins Road, which contains the above described drainage swale. Based on the
stream/wetland delineation, jurisdictional waters are not present on the approximate 5.10-are tract or
within the proposed disturbance limits of the Gallimore Diary Road extension.
USACE RFI 3) Proposed bottomless culverts:
A Please provide a cross section view of the proposed bottomless culvert structures (see item 1)d. above)
clearly showing the outer walls of the culvert structures and footers, disturbance limits needed to
construct the structure, and the stream profile. This information is needed to ensure that this structure
would not result in direct impacts to the stream;
B The Corps Wilmington District Raleigh Regulatory Field Office has had long experience with bottomless
culverts. We generally agree with NCDOT that the long-term success of such structures is significantly
enhanced when they are tied into shallow bedrock. NCDOT Division 7 does not typically pursue
bottomless culverts unless there is non-scourable bedrock within 5 vertical feet of the soil surface. In
cases where the structures are not tied into bedrock we have seen numerous instances of foundation
undercutting, often leading to replacement with traditional culverts. Further, shading under the arch
5

culvert inevitably leads to die -off of any remaining woody vegetation. These factors predictably lead to
loss of aquatic function through stream bank erosion and winnowing out from foundation to
foundation.
C Given that the project proposes impacts requiring 404 approval, we are evaluating both direct and
reasonably foreseeable indirect impacts to 404 resources associated with the project to ensure that the
individual and cumulative adverse environmental effects are no more than minimal (NWP General
Condition 23 and District Engineer's Decision part 2). Based on the above, it is reasonable to conclude
that the proposed bottomless culverts would result in indirect impacts to streams in the footprint of the
structures. The proposed indirect impacts to streams appears to exceed 0.02 acre, the typified stream
mitigation threshold per Regional Condition B.7, in this case. Compensatory mitigation for this
predictable reduction in (though not a total loss of) stream function is typically required at 1:1, unless
otherwise justified based on an evaluation of stream function (i.e. NCSAM).
Applicant Response: See Impact Exhibit 2.0, Gallimore Diary Road Extension PCN. The proposed bottomless arch culvert
does not result in a net loss fill impact to the stream and is being tied to shallow bedrock. It is our opinion that all
factors as outlined in the District Engineers Decision Part 2 of NWP 39 should be evaluated to determine what is or is not
minimal indirect loss or cumulative effect to the environment as a whole, and thus appropriate compensatory
mitigation, if any, for effects that would be considered more than individual or minimal. As noted within District
Engineers Decision Part 2 of NWP 39, "The district engineer will also consider site specific factors, such as the
environmental setting in the vicinity of the NWP activity, the type of resource that will be affected by the NWP activity,
the functions provided by the aquatic resources that will be affected by the NWP activity, the degree or magnitude to
which the aquatic resources perform those functions, the extent that aquatic resource functions will be lost as a result
of the NWP activity (e.g., partial or complete loss), the duration of the adverse effects (temporary or permanent), the
importance of the aquatic resource functions to the region (e.g., watershed or ecoregion), and mitigation required by
the district engineer". While there will be some decreases in aquatic function comparatively to conditions now, it is not
a complete or net loss (i.e. a minimal loss) of aquatic habitat/function and does not prohibit habitat/function or aquatic
passage comparatively to a traditional culvert with bottom. Furthermore, the size of the culvert (width and length) will
minimize the effect of shading impacts and die -back of woody species. Additionally, existing channel stability and local
geology (i.e. low channel slope, no presence of highly erosive soils, etc.) contribute to minimalizing the potential indirect
effect of the bottomless arch culvert to overall watershed or ecoregion. Based on these factors, we have determined
that the loss of aquatic function from the bottomless arch culvert to the stream would not be more than minimal
indirect impact or require compensatory mitigation and would have negligible effect to the overall function of the
watershed or ecoregion.
USACE RFI 4)
USACE RFI 5)
The information provided does not fully justify that Project Elixir is a project with independent utility
from the Gallimore Dairy Road Extension. Specifically, a portion of impacts proposed to Stream MSB are
for an access road that does not connect to any infrastructure (i.e. has no purpose) absent the proposed
Gallimore Dairy Road Extension. Information in item 1 above will be required to evaluate the
independent utility of the Gallimore Dairy Road Extension. Otherwise, note that these projects currently
appear to be part of the same single and complete project to provide required infrastructure to develop
Project Elixir (350 South) and future portions of the High Point North Industrial Center.
It has come to our attention that the area proposed for development of the Gallimore Dairy Road
Extension and Project Elixir (350 South) appear to be phases of the High Point North Industrial Center
(see attached). Generally, the Corps would consider the entire buildout of such an industrial park as a
single and complete project with impacts considered cumulative with respect to NWP and
compensatory mitigation thresholds. Please provide for our evaluation any information available to
justify that Project Elixir (350 South) is a single and complete project with independent utility apart from
the High Point North Industrial Center. Furthermore, even if Project Elixir (350 South) and the Gallimore
Dairy Road Extension are considered part of an overall High Point North Industrial Center single and
complete project, it may still be possible to permit in phases by stacking NWPs if it can be shown that
the reasonably foreseeable impacts associated with full buildout of the High Point North Industrial
6

Center would not exceed the NWP threshold; any information you can provide to this effect would be
useful.
UACCE RFI 6) Thank you for addressing avoidance of indirect impacts to remaining portions of Stream MSB
downstream of the proposed fill slope. Please show the location of the proposed French drain on the zoomed -in
plansheet;
Applicant Response: See updated PCNs. There are no future plans for development within the High Point Industrial
Center. The extension of Gallimore Diary Road from Sandy Ridge to Adkins Road is planned but only Phase A has been
designed. Phase A of the Gallimore Dairy Road extension will provide access to the PNK-High Point project. Phase B of
the Gallimore Diary Road extension would require 2 additional stream crossings. It is the applicant's intention to avoid
exceedance of NWP impact thresholds associated with the construction of the remaining two stream crossings by
utilizing remaining NWP impact amounts and/or the use of bottomless arch culverts or spans. Therefore, at this time
and based on the limited information from conceptual designs, it is not possible for the Applicant to speculate any
future roadway impact or development within the larger High Point Industrial Centers project's purpose and need or if
there would be an impact to waters as a result thereof. The Applicants acknowledges that should the future Phase B of
Gallimore Diary Road extension or other development within the larger High Point North Industrial Center were to
impact jurisdictional waters, then the USACE would need review the project's purpose and need to determine if the road
improvement project or other development within the larger High Point Industrial Center was considered cumulative to
impacts to jurisdictional waters as a result of the proposed project.

All,
Thank you for your PCNs for the above referenced Gallimore Dairy Road Extension and Project Elixir (350 South)
projects, dated 3/8/2022 and 3/16/2022, respectively. I have reviewed the information and need clarification before
proceeding with verifying the use of Nationwide Permits (NWPs) 14 (https://saw-reg.usace.army.mil/NWP2021/NWP-

undercutting, often leading to replacement with traditional culverts. Further, shading under the arch
culvert inevitably leads to die -off of any remaining woody vegetation. These factors predictably lead to
loss of aquatic function through stream bank erosion and winnowing out from foundation to
foundation.
c. Given that the project proposes impacts requiring 404 approval, we are evaluating both direct and
reasonably foreseeable indirect impacts to 404 resources associated with the project to ensure that the
individual and cumulative adverse environmental effects are no more than minimal (NWP General
Condition 23 and District Engineer's Decision part 2). Based on the above, it is reasonable to conclude
that the proposed bottomless culverts would result in indirect impacts to streams in the footprint of the
structures. The proposed indirect impacts to streams appears to exceed 0.02 acre, the typified stream
mitigation threshold per Regional Condition B.7, in this case. Compensatory mitigation for this
predictable reduction in (though not a total loss of) stream function is typically required at 1:1, unless
otherwise justified based on an evaluation of stream function (i.e. NCSAM).
The following items are specific to Project Elixir (350 South):
4) The information provided does not fully justify that Project Elixir is a project with independent utility from the
Gallimore Dairy Road Extension. Specifically, a portion of impacts proposed to Stream MSB are for an access
road that does not connect to any infrastructure (i.e. has no purpose) absent the proposed Gallimore Dairy Road
Extension. Information in item 1 above will be required to evaluate the independent utility of the Gallimore
Dairy Road Extension. Otherwise, note that these projects currently appear to be part of the same single and
complete project to provide required infrastructure to develop Project Elixir (350 South) and future portions of
the High Point North Industrial Center.
5) It has come to our attention that the area proposed for development of the Gallimore Dairy Road Extension and
Project Elixir (350 South) appear to be phases of the High Point North Industrial Center (see attached).
Generally, the Corps would consider the entire buildout of such an industrial park as a single and complete
project with impacts considered cumulative with respect to NWP and compensatory mitigation thresholds.
Please provide for our evaluation any information available to justify that Project Elixir (350 South) is a single
and complete project with independent utility apart from the High Point North Industrial Center. Furthermore,
even if Project Elixir (350 South) and the Gallimore Dairy Road Extension are considered part of an overall High
Point North Industrial Center single and complete project, it may still be possible to permit in phases by stacking
NWPs if it can be shown that the reasonably foreseeable impacts associated with full buildout of the High Point
North Industrial Center would not exceed the NWP threshold; any information you can provide to this effect
would be useful.
6) Thank you for addressing avoidance of indirect impacts to remaining portions of Stream MSB downstream of the
proposed fill slope. Please show the location of the proposed French drain on the zoomed -in plansheet;
Please note that responses to the questions above may prompt additional information requests to allow full evaluation
of the proposed project(s). Also note that it appears that an Individual 401 WQC would be required from NCDWR for the
proposed project(s); the Corps cannot verify the use of any NWP without a valid 401 Water Quality Certification.
Please let me know if you have any questions.
Sincerely,
Dave Bailey
