The proposed Northern Durham Parkway - Phase 2 project area is ±9 acres in size and is aligned
within two parcels (PIN: 0843-09-55-1980 and 0833-98-68-0826). The Northern Durham
Parkway - Phase 2 alignment begins at Hamlin Road and runs northwest where it will terminate
at the existing railroad located southeast of Old Oxford Road and northwest of Hamlin Road in
Durham County (Lat: 36.055084°N; -78.862090°W).
The project is located in the Neuse River basin and onsite waters drain to the Eno River. The
Water Quality Classification for the Eno River is: WS-IV; NSW and the Stream Index Number is:
27-2-(19.5). The cataloging unit for the site is 030202010304.
Proposed Project
The overall purpose of the Northern Durham Parkway - Phase 2 is to provide an alternative route
between Raleigh and Durham. Northern Durham Parkway is a component of the Durham - Chapel
Hill - Carrboro Comprehensive Transportation Plan evaluated as NCDOT State Transportation
Project #U-4721. The purpose of the proposed segment of Northern Durham Parkway is to
construct two lanes of what will eventually become a four-lane divided boulevard of Northern
Durham Parkway that will eventually terminate at Old Oxford Road and Hebron Road.
Additionally, the road will provide access to the future Welcome Venture Park project whose
impacts have been authorized under USACE AID# SAW-2021-02316.
In a preapplication meeting held on 5/23/22 with April Norton of the USACE, it was discussed
that since Northern Durham Parkway is part of the comprehensive transportation plan, and this
portion is not considered a private access for future development it should be permitted separately
from future development as a public transportation project with separate utility. The proposed
impacts in this submittal are necessary for a road crossing of Stream 1, Pond 1, and Wetland A to
construct this portion of the proposed parkway.
Northern Durham Parkway will ultimately be a 4-lane median divided boulevard. The proposed
Northern Durham Parkway - Phase 2 has been designed as a two-lane road. Specifically, the
northern two lanes will be constructed, with the southern two lanes being constructed in the
future once the remainder of Northern Durham Parkway has been constructed and traffic needs
warrant expansion to a 4-lane road. All proposed impacts are necessary for construction of the
northern two lanes only. Impacts necessary to expand to the ultimate 4-lane median divided road
will be permitted separately in the future once the expansion is needed.
Project History
WR completed a wetland delineation for the project area on 9/30/2021. WR submitted a
Preliminary Jurisdictional Determination Request to the USACE on 10/25/2021 (SAW-2021-
02316) for the Welcome Venture Park project that includes the Northern Durham Parkway
alignment. USACE sent a concurrence email on 2/10/2022 confirming concurrence with the PJD
Request, which has been provided as an attachment.
S&EC conducted an onsite Threatened and Endangered Species review on October 5, 2021. The
T&E Report and Self-Certification Letter are included as attachments in this submittal.
NCDWR issued a Buffer Determination Letter(NBRRO#21-445)for the project dated 1/13/2022
which has been provided as an attachment.
NC SHPO issued a letter for the Welcome Venture Park project on 1/26/2022 and did not have
any comments on the project as proposed.

Our People,Your Success.
NCDWR issued a 401 permit for the Welcome Venture Park project on 10/30/2022 (DWR
#20221128) and the USACE issued a 404 permit on 11/17/2022 (SAW-2021-02316) which this
portion of Northern Durham Parkway will provide access to.
Proposed Impacts
The proposed impacts are necessary for construction of a perpendicular road crossing and road
grading for another portion of the parkway. The permanent impacts will occur from installation of
a 10'x10' RCBC culvert and riprap dissipator. The temporary stream impacts will result from
installation of the culvert and construction of the temporary coffer dams to bypass flow during
construction so that work may be completed in the dry.
The proposed permanent stream impact is necessary to construct a culverted road crossing
(Northern Durham Parkway - Phase 2). The road has been designed to cross Stream 1
perpendicularly with a reinforced concrete boxed culvert beneath the road, which will result in
0.017 acres (106 If) of permanent stream impacts with functional loss(Impact S2).The box culvert
has been designed to be buried 12 inches below the stream bed to allow for aquatic life passage.
A riprap dissipator will be installed on the downstream end of the culvert, resulting in 0.006 acres
(43 If) of permanent stream impacts with no functional loss (Impact S3). The riprap dissipator is
necessary to prevent erosion of the stream from drainage from the adjacent land that will be
developed in the future resulting in higher flow velocity during storm events. The riprap will be
installed by burying the riprap such that the top of the riprap matches the pre-construction
contours of the natural stream bed, allowing for the passage of aquatic life and preventing a loss
of stream function.
Construction will be completed in the dry by installing temporary coffer dams and constructing a
temporary bypass swale to convey flow around the construction area. The installation of the
temporary coffer dams and culvert will result in 0.001 acres (10 If) of temporary stream impacts.
Additionally, the construction of the culvert will be scheduled during a period with no forecasted
rain. After construction is complete,the temporary stream impact areas will be restored to natural
grade. The restored stream banks will be stabilized with biodegradable matting placed on the
stream banks and seeded with rye grass to provide temporary stabilization until natural
regeneration of native vegetation permanently stabilizes the banks. No matting will be placed on
the stream bed.
Permanent impacts to a pond (Pond 1) and an adjacent wetland (Wetland A) are necessary and
unavoidable due to construction of the proposed project. Impacts to both features are due to
grading to achieve the necessary grade for the roadway. Total impact amounts from the proposed
project to Pond 1 are 0.279 acres (Impact 01) and Wetland A are 0.069 ac (Impact W1).
The Stream 1 crossing will result in 12,566 sf of permanent Zone 1 impacts and 13,214 sf of
permanent Zone 2 impacts. The total permanent riparian buffer impacts will be 0.59 acres and
therefore is classified as "Allowable with Mitigation Upon Authorization" in the 2020 Neuse River
Riparian Buffer Rules (i.e., impact greater than one-third of an acre of riparian buffer).
Avoidance and Minimization
Prior to site plan design,the applicant requested that a detailed wetland delineation be conducted
so that impacts to wetlands and "waters" could be minimized.
Page 3 of 6

Northern Durham Parkway- Phase 2 - NWP 14 ;0 WithersRavenel
Durham, Durham Co.
Our People,Your Success.
Impacts have been minimized to only those necessary for a single road crossing to construct the
parkway and access developable uplands.
The Northern Durham Parkway - Phase 2 stream crossing has been designed to cross Stream 1 at
a perpendicular angle at a straight segment of stream channel.Additionally,wing walls will be used
to stabilize road fill at the culvert rather than traditional backslopes.
The riprap dissipator below the access road culvert will be constructed such that the riprap will be
installed by burying the riprap such that the top of the riprap matches the pre-construction
contours of the natural stream bed, allowing for the passage of aquatic life and preventing a loss
of function of stream channel.
Upon completion of construction, the temporarily impacted stream channel will be restored to
pre-construction conditions and grades,and temporarily stabilized with biodegradable matting and
seeded to provide temporary stabilization until natural regeneration of native vegetation
permanently stabilizes the stream banks. No matting will be placed on the stream bed.
The Northern Durham Parkway- Phase 2 alignment was designed to align with existing designated
alignment of Northern Durham Parkway in Durham's future transportation plan. Additionally, the
proposed alignment is necessary to avoid existing buildings and homes.To avoid additional stream
and buffer impacts on the site, impacts to a small pond (Pond 1) and adjacent wetland are
unavoidable.
Pond 1 is not subject to the Neuse buffer rules and impacts to both the remaining portion of the
pond and the wetland are due to road grading and a portion of the roadway itself. Approximately
one-half of the existing pond was authorized to be filled by previously issued 404 and 401 permits
(SAW-2021-02316 & DWR#20221128) for the Welcome Venture Park project.
Construction techniques used to avoid or minimize impacts include installation of erosion &
sediment control devices prior to construction activities and construction access occurring from
uplands.
Mitigation
Stream Mitigation
The proposed project will result in 0.023 acres (149 If) of permanent stream impacts, of which
0.017 ac (106 If)will result in functional loss.
The applicant proposes to mitigate for the 0.017 ac (106 If) of functional loss at a 2:1 mitigation
ratio,resulting in the provision of 212 If of stream mitigation.WithersRavenel contacted mitigation
banks that service the Neuse 03020201 basin within the Falls Lake Watershed to determine
availability of stream mitigation credits.The letter of acceptance from RES for the 212 If of stream
mitigation has been provided as an attachment.
Wetland Mitigation
The proposed project will result in 0.069 acres of permanent wetland impacts as depicted in the
table below. The proposed wetland impacts are less than a tenth of an acre however, Northern
Durham Parkway is a portion of a larger project and wetland impacts are required to be offset with
mitigation. The applicant proposes to mitigate for the 0.069 ac loss at a 2:1 mitigation ratio,
resulting in the provision of 0.138 ac of wetland mitigation. WithersRavenel contacted mitigation
banks that service the Neuse 03020201 basin within the Falls Lake Watershed to determine
Page 4 of 6

Our People,Your Success.
availability of wetland mitigation credits. The letter of acceptance from RES for the 0.138 ac of
wetland mitigation has been provided as an attachment.
Buffer Mitigation
The stream/buffer crossing will result in 12,566 sf of permanent Zone 1 impacts and 13,214 sf of
permanent Zone 2 impacts, which totals 0.59 acres. The crossing is classified as "Allowable with
Mitigation Upon Authorization"and therefore riparian buffer mitigation is required. The applicant
proposes to provide 57,519 sf of riparian buffer mitigation as documented in the following table:
Buffer Mitigation Table
Impact Requiring
Zone Mitigation Multiplier Total
Zone 1 12,566 sf 3 37,698 sf
Zone 2 13,214 sf 1.5 19,821 sf
Total Mitigation Required 57,519 sf
WithersRavenel contacted mitigation banks that service the Neuse 03020201 basin within the
Falls Lake Watershed to determine availability of buffer mitigation. The applicant proposes to
provide the 57,519 sf of riparian buffer mitigation through purchase of credits from RES. The
Statement of Availability from Wildlands Holdings has been provided as an attachment.
Stormwater Management Plan
Stormwater from the proposed roadway will be routed to SCM's located within the adjacent
Welcome Venture commercial development. Stormwater not captured will be conveyed as sheet
flow. The stormwater management plan for Welcome Venture development consists of five
constructed stormwater wetland SCMs and one SCM pond which provide a minimum of 30%
nitrogen removal and therefore diffuse flow is not required. The stormwater management plan
will be reviewed and approved by the City of Durham as the certified municipality.
Please feel free to call if you have questions or require additional information to complete your
review.
Sincerely,
WithersRavenel

E. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts through project design:
Prior to site plan design, the applicant requested that a detailed wetland delineation be conducted so that
impacts to wetlands and "waters" could be minimized.
Impacts have been minimized to only those necessary for road crossings to construct the Northern Durham
Parkways and to provide access to the Welcome Venture Park project.
The Northern Durham Parkway—Phase 2 stream crossing has been designed to cross Stream 1 at a
perpendicular angle at straight segment of stream channel. Additionally, wing walls will be used to stabilize road
fill rather than traditional backslopes.
The riprap dissipator below the access road culvert will be constructed such that the riprap will be installed by
burying the riprap such that the top of the riprap matches the pre-construction contours of the natural stream
bed, allowing for the passage of aquatic life and preventing a loss of function of this section of stream channel.
Upon completion of construction, the temporarily impacted stream channel will be restored to pre-construction
conditions and grades, and temporarily stabilized with biodegradable matting and seeded with rye grass to
provide temporary stabilization until natural regeneration of native vegetation permanently stabilizes the stream
banks. No matting will be placed on the stream bed.
The Northern Durham Parkway- Phase 2 alignment was designed to align with existing designated alignment of
Northern Durham Parkway in Durham's future transportation plan. Additionally, the proposed alignment is
necessary to avoid existing buildings and homes. To avoid additional stream and buffer impacts on the site,
impacts to a small pond (Pond 1) and adjacent wetland are unavoidable.
Pond 1 is not subject to the Neuse buffer rules and impacts to both the remaining portion of the pond and the
wetland are due to road grading and a portion of the roadway itself. Approximately one-half of the existing pond
was authorized to be filled by previously issued 404 and 401 permits (SAW-2021-02316 & DWR#20221128).
1 b. Specifically describe measures taken to avoid or minimize proposed impacts through construction techniques:
Construction techniques used to avoid or minimize impacts include installation of erosion & sediment control
devices prior to construction activities and construction access occurring from uplands.

Wedgemussel, Monarch Butterfly, Michaux's Sumac, and Smooth Coneflower have ranges that extend into the
project area. The IPaC specified that there are no critical habitats within the project area. The IPaC species list
has been provided as an attachment to this application.
S&EC reviewed the NC Natural Heritage Program database, located at https://ncnhde.natureserve.org/, as well
as NCNHP GIS data to identify if there were any known occurrences of endangered species on or near the
proposed project. The review of the NHP data did not identify any recent occurrences of federally listed
threatened or endangered species or critical habitat on the subject property. Recent occurrences of Smooth
Coneflower and Michaux's Sumac have been observed within 1.0 miles of the project. A number of natural areas
are located within a one mile radius of the project area. On October 5, 2021 S&EC conducted site assessments
to identify potential suitable habitat and surveys for species listed on the official species list. S&EC completed a

Dear Alyssa Ricci,
Reference is made to Corps Action ID: SAW-2021-02316. Please reference this number on any
correspondence regarding this action.
We have reviewed the information provided by you concerning the aquatic resources, and by copy
of this e-mail, are confirming that the aquatic resources delineation has been verified by the Corps
to be a sufficiently accurate and reliable representation of the location and extent of aquatic
resources within the identified review area. The location and extent of these aquatic resources are
shown on the delineation map entitled, "Preliminary Jurisdictional Determination Request Exhibit"
and dated 2/9/2022.
Regulatory Guidance Letter(RGL) 16-01
https://usace.contentdm.ocic.org/utils/getfile/collection/pl602lco119/id/1256 provides guidance for
Jurisdictional Determinations (JD) and states, "The Corps generally does not issue a JD of any type
where no JD has been requested." Currently, we are only verifying the delineation. This delineation
may be relied upon for use in the permit evaluation process, including determining compensatory
mitigation. This verification does not address nor include any consideration for geographic
jurisdiction on aquatic resources and shall not be interpreted as such.
This delineation verification is not an Approved Jurisdictional Determination (AJD) and is not an
appealable action under the Regulatory Program Administrative Appeal Process (33 CFR Part 331).
However, you may request an AJD, which is an appealable action.
If you wish to receive a Preliminary Jurisdictional Determination (PJD), or an Approved Jurisdictional
Determination (AJD) please respond accordingly, otherwise nothing further is required and we will
not provide any additional documentation.
**Due to workload volume, it may take 90- 120 days or more for the issuance of a standalone JD;
however, you may use the delineation for planning and permitting purposes.
Thank you,

Explanation: The stream(s)/pond(s)listed above has been located on the most recent published NRCS Soil Survey
of Durham County,North Carolina and/or the most recent copy of the USGS Topographic map at a 1:24,000 scale.
Each feature that is checked"Not Subject"has been determined to not be an intermittent stream,perennial stream,a
pond connected to a stream feature,or the feature is determined not to be present. Stream features that are checked
"Subject"have been located on the property and possess characteristics that qualify them to be subject to the buffer
rules. There may be other streams located on the property that are not depicted on the maps referenced above and
are therefore not subject to the buffer rules. However, if the stream features are present on the tract they are subject
to all other applicable North Carolina stream standards and permitting requirements as outlined in 15A NCAC 02B,
and may be considered jurisdictional according to the US Army Corps of Engineers.
This on-site determination shall expire five(5)years from the date of this letter. Landowners or affected
parties that dispute a determination made by the DWR may request a determination by the Director. An
appeal request must be made within sixty(60)days of date of this letter. A request for a determination by the
Director shall be referred to the Director in writing. If sending via US Postal Service: c/o Paul Wojoski;DWR

Re: THREATENED & ENDANGERED SPECIES REPORT
Eno Venture Park(+/- 160.73 acres)
Hamlin Rd, Durham, Durham County,NC
Dear Mr. Kakambouras:
On October 5, 2021, Soil& Environmental Consultants, PA(S&EC) evaluated the Eno Venture Park
property shown on the attached maps for potential endangered species. The property is located at Hamlin
Rd in Durham County,NC. Surface waters on-site flow into the Eno River in the Neuse River Basin,
which has been classified in the"Classification and NC DWQ Standards Applicable to Surface Waters
and Wetlands of North Carolina" as WS-IV;NSW.
We obtained the attached automatically generated official species list from the U.S. Fish&Wildlife
Service(FWS) and N.C.Natural Heritage Program(NHP)report identifying the protected species on or
within one mile of the project area that could potentially be affected by the project. These FWS &NHP
reports were updated as of the date of this report. The official species list is valid for 90 days.
We conducted site assessments to identify potential suitable habitat and preliminary surveys for the
individual species listed on the official species list. This included assessing the physical characteristics of
the streams, identifying forest types, and looking for evidence of the listed species on-site. This survey
did not include any detailed sampling or netting. The results of the search are discussed below.
Eno Venture Park-S&EC Threatened &Endangered Species Report
Page 1 of 6

October 19,2021
S&EC Project#14972.W1
RESULTS:
The FWS official species list identified the following threatened and endangered species for the
Evaluation limits:
• Neuse River Waterdog (Necturus lewisi), Proposed Threatened
• Carolina Madtom(Noturus furiosus), Proposed Endangered
• Atlantic Pigtoe (Fusconaia masoni), Proposed Threatened
• Dwarf Wedgemussel (Alasmidonta heterodon), Endangered
• Michaux's Sumac (Rhus michauxii), Endangered
• Smooth Coneflower(Echinacea laevigata), Endangered
Of the species identified on the official species list, the NHP report did identify thirteen Federally
threatened or endangered species within one mile of the project area. Other State listed species were
found within the project area as listed in the attached NHP report. The NHP report identified seven
natural areas and seventeen managed areas within the project area or within one mile of the project
area. These are listed out in the attached NHP Report.
NEUSE RIVER WATERDOG(Necturus lewisi):
S&EC personnel conducted preliminary surveys of the streams on-site for potential suitable habitat for
the Neuse River Waterdog. The NHP report did list a known elemental occurrence from 2020 within
one mile of the site. This species is found in the Neuse River and Tar River basins. The suitable habitat
this species is found in is typically medium to large streams and rivers with a moderate gradient and
large bed material. The Neuse River Waterdog also needs riffles, runs, and pools. While we did not
specifically sample for the species,we also did not find any evidence of the species while conducting
our preliminary surveys of the streams for potential suitable habitat.
Our preliminary survey concluded that potential suitable habitat does not exist on-site. The streams on-
site were+/-4 feet wide with low or no baseflow and had a sandy gravel substrate. Due to these
observations,we have concluded that the project would have "No effect" on the Neuse River
Waterdog.

Page 2 of 6

October 19,2021
S&EC Project#14972.W1
CAROLINA MADTOM(Noturus furiosus):
S&EC personnel conducted preliminary surveys of the streams on-site for potential suitable habitat for
the Carolina Madtom (Note: This did not include a detailed aquatic mussel survey for the presence of
mussels). The NHP report did list a known historical elemental occurrence from 1961 within one mile
of the site. This species is found in the Neuse River and Tar River basins. The suitable habitat this
species is found in is also medium to large streams and rivers with a moderate gradient and large bed
material. The Carolina Madtom also needs continuous year-round flow and cover for nesting habitat.
While we did not specifically sample for the species, we also did not find any evidence of the species
while conducting our preliminary surveys of the streams for potential suitable habitat.
Our preliminary survey concluded that potential suitable habitat does not exist on-site. The streams on-
site were +/-4 feet wide with low or no baseflow and had a sandy gravel substrate. Due to these
observations,we have concluded that the project would have "No effect" on the Carolina Madtom.
ATLANTIC PIGTOE (Fusconaia masonal:
S&EC personnel conducted preliminary surveys of the streams on-site for potential suitable habitat for
the Atlantic Pigtoe(Note: This did not include a detailed aquatic mussel survey for the presence of
mussels). The NHP report did not list any known elemental occurrence within the project area or
within one mile of the site. The suitable habitat for this species consists of medium sized creeks to large
rivers with excellent water quality. This species typically lives in streams with coarse sand and gravel
with moderate to high flowing water. While we did not specifically sample for the species, we also did
not find any evidence of the species while conducting our preliminary surveys of the streams for
potential suitable habitat.
Our preliminary survey concluded that potential suitable habitat does not exist on-site. The streams on-
site were+/-4 feet wide with low or no baseflow and had a sandy gravel substrate. Due to these
observations,we have concluded that the project would have "No effect" on the Atlantic Pigtoe.
DWARF WEDGEMUSSEL (Alasmidonta heterodon):
S&EC personnel conducted preliminary surveys of the streams on-site for potential suitable habitat for
the Dwarf Wedgemussel (Note: This did not include a detailed aquatic mussel survey for the presence of
Eno Venture Park-S&EC Threatened &Endangered Species Report
Page 3 of 6

October 19,2021
S&EC Project#14972.W1
mussels). The NHP report did not list any known elemental occurrence within the project area or
within one mile of the site. The Dwarf Wedgemussel has little to no preference for stream size, flow
condition or bed material. Based on guidance from the USFWS staff, only 2nd order and larger perennial
streams are considered suitable habitat. While we did not conduct detailed mussel surveys,no mussels
(of any species)were observed during the preliminary suitable habitat survey.
Our preliminary survey concluded that potential suitable habitat does not exist on-site. The streams on-
site were+/-4 feet wide with low or no baseflow and had a sandy gravel substrate. Due to these
observations,we have concluded that the project would have "No effect" on the Dwarf Wedgemussel.
MICHAUX'S SUMAC (Rhus michauxib:
S&EC personnel conducted preliminary surveys of suitable habitat within the project area. We visited
a known population of Michaux's sumac within Wake County prior to conducting our preliminary
surveys. We found no individual Michaux's Sumac species within the project area. The NHP report
did list a known elemental occurrence from 2020 within 1 mile of the project area. We found suitable
habitat within the project areas to include primarily disturbed open areas along roads,paths, easements,
ponds, and logged areas. Other sumac species identified on-site included Winged sumac (Rhus
copallinum). Given the lack of species present within the areas believed to be suitable habitat, we
concluded that the project would have "No effect" on Michaux's sumac.
SMOOTH CONEFLOWER(Echinacea laevizata):
S&EC personnel conducted preliminary surveys of suitable habitat within the project area. We found
no individual Smooth Coneflower species within the project area. The NHP report listed nine known
elemental occurrence from 2020 and earlier within one mile of the project area. We found suitable
habitat within the project areas to include primarily disturbed open areas along roads,paths, easements,
and cleared areas. Given the lack of species present within the areas believed to be suitable habitat, we
concluded that the project would have "No effect" on Smooth Coneflower.
BALD EAGLE (Haliaeetus leucocephalus):
S&EC personnel conducted preliminary surveys of suitable habitat, nesting sites, and individual Bald
Eagles within the project area. During our survey,we found no evidence of Bald Eagles or any nesting

sites within the project area. The NHP report did not identify any known nests on-site or within one
mile of the site. Given the lack of species present,we have concluded that the project is "Unlikely to
disturb nesting bald eagles". We believe no Eagle Act Permit is required.
NORTHERN LONG-EARED BAT (Myotis septentrionalis):
S&EC personnel conducted preliminary surveys for suitable habitat and individual Northern Long-
eared Bats (NLEB's)within the project area. During our survey, we found no individual species.
Relying upon the findings of the 1/5/2016 Programmatic Biological Opinion for Final 4(d) Rule on the
Northern Long-Eared Bat and Activities Excepted from Take Prohibitions to fulfill our project-specific
section 7 responsibilities." Due to the nature of the project being Industrial development, we
concluded that the project would"May affect, but not likely to adversely affect"NLEB's.
CONCLUSION:
After completing the habitat assessments and preliminary surveys, S&EC completed the attached
"Species Conclusion Table" and"Self-Certification Letter". Using language typically used by the FWS
in their conclusion letters, we have concluded that it appears the proposed project is not likely to
adversely affect any federally listed endangered or threatened species, their formally designated
critical habitat, or species currently proposed for listing under the Endangered Species Act(ESA).
We strongly recommend requesting a concurrence letter from the FWS.

Event Code: 04EN2000-2021-E-04707
Project Name: Eno Venture Park
Subject: List of threatened and endangered species that may occur in your proposed project
location or may be affected by your proposed project
To Whom It May Concern:
The species list generated pursuant to the information you provided identifies threatened,
endangered, proposed and candidate species, as well as proposed and final designated critical
habitat, that may occur within the boundary of your proposed project and/or may be affected by
your proposed project. The species list fulfills the requirements of the U.S. Fish and Wildlife
Service (Service) under section 7(c) of the Endangered Species Act(Act) of 1973, as amended
(16 U.S.C. 1531 et seq.).
New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could change this list. Please feel free to
contact us if you need more current information or assistance regarding the potential impacts to
federally proposed, listed, and candidate species and federally designated and proposed critical
habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the
Act, the accuracy of this species list should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the ECOS-IPaC website at regular intervals during project planning and
implementation for updates to species lists and information.An updated list may be requested
through the ECOS-IPaC system by completing the same process used to receive the enclosed list.
Section 7 of the Act requires that all federal agencies (or their designated non-federal
representative), in consultation with the Service, insure that any action federally authorized,
funded, or carried out by such agencies is not likely to jeopardize the continued existence of any
federally-listed endangered or threatened species. A biological assessment or evaluation may be
prepared to fulfill that requirement and in determining whether additional consultation with the
Service is necessary. In addition to the federally-protected species list, information on the
species' life histories and habitats and information on completing a biological assessment or

09/23/2021 Event Code: 04EN2000-2021-E-04707 2
evaluation and can be found on our web page at http://www.fws.gov/raleigh. Please check the
web site often for updated information or changes
If your project contains suitable habitat for any of the federally-listed species known to be
present within the county where your project occurs, the proposed action has the potential to
adversely affect those species. As such, we recommend that surveys be conducted to determine
the species' presence or absence within the project area. The use of North Carolina Natural
Heritage program data should not be substituted for actual field surveys.
If you determine that the proposed action may affect (i.e., likely to adversely affect or not likely
to adversely affect) a federally-protected species, you should notify this office with your
determination, the results of your surveys, survey methodologies, and an analysis of the effects
of the action on listed species, including consideration of direct, indirect, and cumulative effects,
before conducting any activities that might affect the species. If you determine that the proposed
action will have no effect (i.e., no beneficial or adverse, direct or indirect effect) on federally
listed species, then you are not required to contact our office for concurrence (unless an
Environmental Impact Statement is prepared). However, you should maintain a complete record
of the assessment, including steps leading to your determination of effect, the qualified personnel
conducting the assessment, habitat conditions, site photographs, and any other related articles.
Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle
Protection Act(16 U.S.C. 668 et seq.), and projects affecting these species may require
development of an eagle conservation plan (http://www.fws.gov/windenergy/
eagle_guidance.html). Additionally, wind energy projects should follow the wind energy
guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and
bats.
Guidance for minimizing impacts to migratory birds for projects including communications
towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http://
www.fws.gov/migratorybirds/CurrentBirdlssues/Hazards/towers/towers.htm; http://
www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/
towers/comtow.html.
Not all Threatened and Endangered Species that occur in North Carolina are subject to section 7
consultation with the U.S Fish and Wildlife Service. Atlantic and shortnose sturgeon, sea
turtles,when in the water, and certain marine mammals are under purview of the National Marine
Fisheries Service. If your project occurs in marine, estuarine, or coastal river systems you should
also contact the National Marine Fisheries Service, http://www.nmfs.noaa.gov/
We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Tracking Number in
the header of this letter with any request for consultation or correspondence about your project
that you submit to our office. If you have any questions or comments, please contact John Ellis
of this office at [e-mail].

Endangered Species Act Species
There is a total of 7 threatened, endangered, or candidate species on this species list.
Species on this list should be considered in an effects analysis for your project and could include
species that exist in another geographic area. For example, certain fish may appear on the species
list because a project could affect downstream species.
IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA
Fisheries1, as USFWS does not have the authority to speak on behalf of NOAA and the
Department of Commerce.
See the "Critical habitats" section below for those critical habitats that lie wholly or partially
within your project area under this office's jurisdiction. Please contact the designated FWS office
if you have questions.

The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached `Documented Occurrences' tables and map.
The attached `Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one-mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one-mile
radius of the project area, if any, are also included in this report.
If a Federally-listed species is documented within the project area or indicated within a one-mile
radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service
(USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Di rectory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional
correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Land and Water Fund
easement, or an occurrence of a Federally-listed species is documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at rod nev.butler(c�ncdcr.gov or 919-707-8603.
Sincerely,
NC Natural Heritage Program

Re Project: Northern Durham Parkway Phase 2
This document confirms that City of Durham (Applicant) for the Northern Durham Parkway Phase 2
(Project)has expressed an interest to utilize 0.138 Riparian Wetland Mitigation Credits from the EBX-
Neuse sponsored Neu-Con Wetland & Stream Umbrella Mitigation Bank, specifically wetland credits
from the Blackbird Site, in the Neuse HUC 03020201. As the official Bank Sponsor, EBX-Neuse I, LLC,
attests to the fact that mitigation is available for reservation at this time.
These mitigation credits are not considered secured, and consequently are eligible to be used for alternate
purposes by the Bank Sponsor, until payment in full is received from the Applicant resulting in the
issuance of a Mitigation Credit Transfer Certificate by the bank acknowledging that the Applicant has
fully secured credits from the bank and the Banker has accepted full responsibility for the mitigation

Re Project: Northern Durham Parkway Phase 2
This document confirms that City of Durham (Applicant) for the Northern Durham Parkway Phase 2
(Project) has expressed an interest to utilize 212.00 Stream Mitigation Credits from the EBX-Neuse
sponsored Neu-Con Wetland & Stream Umbrella Mitigation Bank, specifically 212.00 stream credits
from the Bucher Site, in the Neuse HUC 03020201. As the official Bank Sponsor, EBX-Neuse I, LLC,
attests to the fact that mitigation is available for reservation at this time.
These mitigation credits are not considered secured, and consequently are eligible to be used for alternate
purposes by the Bank Sponsor, until payment in full is received from the Applicant resulting in the
issuance of a Mitigation Credit Transfer Certificate by the bank acknowledging that the Applicant has
fully secured credits from the bank and the Banker has accepted full responsibility for the mitigation
obligation requiring the credits/units.
The Banker will issue the Mitigation Credit Transfer Certificate within three (3) days of receipt of the
purchase price. Banker shall provide to Applicant a copy of the Mitigation Credit Transfer Certificate and
a documented copy of the debit of credits from the Bank Official Credit Ledger(s), indicating the permit
number and the resource type secured by the applicant. A copy of the Mitigation Credit Transfer
Certificate, with an updated Official Credit Ledger will also be sent to regulatory agencies showing the
