D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Avoidance of the stream can not be accomplished it is required that this entrance be placed directly across Davis Drive from an existing road. The
culvert extension length has been minimized as much as possible with a headwall placed at the end. Additionally the roadway width has been set to
the minimum widths.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The limits of disturbance have been set to allow for the minimal distance for construction. The pipe and stream stabilization work will be preformed
from the top of the stream bank. No equipment will be placed in the channel. A stream pump around will be used for construction.

Documentation for Pre - Construction Notification (PCN) Form
ARE -NC Region No. 14, LLC Davis Drive Entrance Road, Research Triangle Park Durham County
B Project Information and Prior Project History
3a. Project Description
The project is located at 6 Davis Drive, Research Triangle Park, in Durham County. A proposed
building and parking areas are planned to be developed on site along with an entrance Road that
will serve the site and the existing Hamner Building on the adjacent property. The entrance drive
will require the extension of an existing 60 -inch culvert that passes under Davis Drive flowing
northeast to southwest on Burdens Creek Tributary 4 a FEMA regulated stream. The pipe is
corrugated metal on the upstream end (east side of the road) and reinforced concrete pipe
(RCP), on the downstream end. It is assumed the pipe was extended in the past for road
improvements, and the culvert was extended with different pipe material.
The proposed entrance drive is on the west side of Davis Drive, immediately across the road
from Entry Drive as required by NCDOT. The culvert extension has been coordinated with NCDOT
for future upgrades. The current 60 inch culvert is not large enough to handle the 50 year storm
event and therefore is anticipated to be upgraded to a larger pipe in the future. The extension
therefore is proposed to be completed with a junction box and larger pipe arch to the outlet. In
the future NCDOT will be able to upgrade the 60 inch pipe to this larger pipe arch and tie into the
constructed junction box. The pipe arch size and proposed design has been coordinated with
NCDOT.
3d. Explain the purpose of the project.
The proposed project is located in Durham, North Carolina. The proposed driveway entrance will
be located approximately 1700 feet north of 1 -40 along Davis Drive. The driveway is required to
be installed directly opposite an existing roadway Entry Drive. This location requires the
extension of an existing 60 inch culvert under Davis Drive on Burdens Creek Tributary 4.
An alternative location for the proposed driveway is not possible due to the requirement of
NCDOT to align the proposed driveway directly across Davis Drive from Entry Drive which is an
existing road. Therefore encroachment into Burdens Creek Tributary 4 is required to extend the
existing pipe to maintain stormwater conveyance across Davis Drive. The proposed entrance
drive is required for the proposed development to meet City development standards to handle
the additional traffic volume expected for the property and emergency vehicles.
Encroachment is required into Burdens Creek Tributary 4, for the proposed entrance drive due
to the location required by NCDOT. The pipe extension has been minimized as much as possible
to only accommodate the needed driveway width for the development. The outlet pipe
extension has also been sized and coordinated with NCDOT to provide for future upgrade of the
existing 60 inch pipe across Davis Drive to prevent future disturbance to Burdens Creek
Tributary 4.
PCN Documentation 1 Davis Drive Entrance Road
RTP Durham County

3e. Describe the overall protect in detail, including the type of equipment to be used.
The project consists of the construction of parking lots buildings and an entrance drive over
Burdens Creek Tributary 4. The proposed driveway will be constructed over the existing location
of the outlet of the 60 inch culvert. Therefore, the culvert is planned to be extended.
Approximately 10.5 linear feet of 60 inch pipe will be installed from the current pipe outlet to
the proposed junction box. This junction box is proposed to be installed in the entrance to
provide NCDOT with maintenance access to their pipe across Davis Drive. The junction box has
also been provided and sized to serve as a tie in location for a larger pipe arch in the future when
the existing 60 -inch pipe is upgraded. The junction box will also prevent future disturbance to
Burdens Creek Tributary 4 in the future. The proposed pipe out of the junction box has been
designed in coordination with NCDOT as a pipe arch in anticipation of future NCDOT pipe
upgrades to the existing 60 -inch pipe under Davis Drive. The proposed parking lots and buildings
have been placed outside of the disturbance of any wetlands, jurisdictional streams, and stream
buffers on the project site. The only wetland, stream, and buffer impacts will occur at the
proposed entrance drive with the pipe extension.
The equipment to be used in the project is earth moving equipment and various other support
apparatuses. Construction equipment may include hydraulic excavators, compactors, bulldozers,
skid steer loaders, and dump trucks to load and unload materials. The construction equipment
will enter from the public street and will perform all construction within a defined limit of
disturbance. Only trees obstructing the creek bank within the pipe extension and bank
stabilization areas as shown on the plans will be removed.

Dear Mr Smith,
December 19, 2014
ECS Carolinas, LLP (ECS) is pleased to provide our results of the Limited National
Environmental Policy Act (NEPA) Database Review conducted for the above - referenced site
Our services were provided in accordance with ECS Proposal No. 06- 18137.
BACKGROUND INFORMATION
The site is located at 6 Davis Drive in Durham, Durham County, North Carolina (Figures 1 and 2)
According to Durham County Online GIS Database, the site consists of two contiguous parcels that
are identified as Parcel Identification Numbers (PINs) 0748 -03 -12 -4785 (13 59- acres) and 0748-
03 -02 -7196 (42 4- acres) ECS understands that a portion of both parcels are to be evaluated
(approximately 2 acres in size) The parent parcel is currently developed with Hamner Institute for
Health Services and several additional structures. No structures were observed on -site Other
areas on the site consist of undeveloped, wooded land. Based on the United States Geological
Survey (USGS) Topographic Map, two unnamed tributaries to Burdene Creek are located along
the southeastern portion of the site
ECS was contracted to conduct a preliminary threatened and endangered species
determination and a preliminary historic and archaeological resources review for the site ECS
personnel conducted the field reconnaissance on November 6, 2014
PRELIMINARY THREATENED AND ENDANGERED SPECIES DETERMINATION
Congress passed the Endangered Species Act (ESA) in 1973 The purpose of the ESA is to
protect and recover imperiled species _and the ecosystems upon-which-they depend It is
administered by the U S Fish and Wildlife Service ( USFWS) and the Commerce Department's
National Marine Fisheries Service (NMFS) The USFWS has primary responsibility for terrestrial
and freshwater organisms, while the responsibilities of NMFS are mainly marine wildlife
Under the ESA, species may be listed as either endangered or threatened "Endangered"
means a species is in danger of extinction throughout all or a significant portion of its range
"Threatened" means a species is likely to become endangered within the foreseeable future All
species of plants and animals, except pest insects, are eligible for listing as endangered or
threatened. For the purposes of the ESA, Congress defined species to include subspecies,
varieties, and, for vertebrates, distinct population segments

Species /Habitat Description
Bald Eaale
E = Endangered
Description: Distinguished by a white head and white tail feathers, Bald eagles are powerful,
brown birds that may weigh up to 14 pounds and have a wingspan of up to 8 feet Male eagles
are smaller, weighing as much as 10 pounds and have a wingspan of 6 feet Sometimes
confused with Golden eagles, Bald eagles are mostly dark brown until they are four to five years
old and acquire their characteristic coloring
Habitat: Bald eagles live near rivers, lakes, and marshes where they can find fish, their staple
food Bald eagles will also feed on waterfowl, turtles, rabbits, snakes, and other small animals
and carrion Bald eagles require a good food base, perching areas, and nesting sites Their
habitat includes estuaries, large lakes, reservoirs, rivers, and some seacoasts In winter, the
birds congregate near open water in tall trees for spotting prey and night roosts for sheltering
Conclusions: The approximate 2 -acre site consists of wooded land and three streams The
wooded areas consist of mature and immature hardwood and pine trees, approximately 20 to 50
years in age Moderately dense understory is present throughout the wooded areas Three
streams are located on the southeastern portion of the site The streams varied from
approximately two to fifteen feet in width and one to ten feet in depth The streams have well
defined bed-and- banks, moderate to heavy baseflow, moderate - sinuosity, and- assorted
substrates Wetland areas are located adjacent and abutting the stream features located on the
site. Large bodies of water and a steady food support base are not believed to be present on
the site or in surrounding areas Based on our knowledge and site observations, suitable
habitat for the Bald eagle is not likely present on the site
Michaux's Sumac
Description: Michaux's sumac is a rhizomatous, densely hairy shrub, with erect stems from one
to three feet in height The compound leaves contain evenly serrated, oblong to lanceolate,
acuminate leaflets Most plants are unisexual, however, more recent observations have

revealed plants with both male and female flowers on one plant The flowers are small, borne In
a terminal, erect, dense cluster, and colored greenish yellow to white Flowering usually occurs
from June to July, while the fruit, a red drupe, Is produced through the months of August to
October.
Habitat: Michaux's sumac grows in sandy or rocky open woods in association with basic soils
Apparently, this plant survives best In areas where some form of disturbance has provided an
open area. Several populations in North Carolina are located on highway right -of ways,
roadsides, or on the edges of artificially maintained clearings Other populations are in areas
with periodic fires, and two populations exist on sites undergoing natural succession One
population is situated in a natural opening on the rim of a Carolina Bay
Conclusion: The approximate 2 -acre site consists of wooded land and three streams The
wooded areas consist of mature and immature hardwood and pine trees, approximately 20 to 50
years in age Moderately dense understory is present throughout the wooded areas No
Carolina Bays or highway right -of -ways are located on -site Roadsides and artificial clearings
located on the parent property appear well maintained Based on our knowledge and site
observations, suitable habitat for the Michaux's sumac is not likely present on -site
Smooth Coneflower
Description: Smooth coneflower is a perennial herb in the Aster family (Asteraceae) that grows
up to 3 3 feet tall from a vertical root stock. The large elliptical to broadly lanceolate basal leaves
may reach up to 8 Inches in length and 3 0 inches in width and taper into long petioles toward
the base. The leaves are smooth to slightly rough in texture The stems are smooth with few
leaves. The mid -stem leaves are smaller than the, basal leaves and have shorter petioles.
Flower heads are usually solitary The rays of the flowers (petal -like structures) are light pink to
purplish In color, usually drooping, and 2 to 3 2 inches long. Flowering occurs from late May
through mid -July and fruits develop from late June to September The fruiting structures often
persist through the fall Reproduction is accomplished both sexually (by seed) and asexually (by
rhizome)
Habitat: Smooth coneflower Is typically found in open woods, glades, cedar barrens, roadsides,
clearcuts, dry limestone bluffs, and power line right -of -ways, usually on magnesium- and
calcium- rich soils associated with amphibollte, dolomite, or limestone (in Virginia), gabbro (in
North Carolina and Virginia), diabase (in North Carolina and South Carolina), and marble (In
South Carolina and Georgia) Smooth coneflower occurs in plant communities that have been
described as xeric hardpan forests, diabase glades, or dolomite woodlands Optimal sites are
characterized by abundant sunlight and little -competition -m- the - herbaceous -layer - Natural fires-
as well as large herbivores, historically influenced the vegetation in this species' range Many of
the herbs associated with smooth coneflower are also sun - loving species that depend on
periodic disturbances to reduce the shade and competition of woody plants
Conclusion: The approximate 2 -acre site consists of wooded land and three streams. The
wooded areas consist of mature and Immature hardwood and pine trees, approximately 20 to 50
years in age A moderately dense understory and herbaceous layer are present throughout the
wooded areas Roadsides, artificial clearings, power line right -of -ways or clearcuts are not
located on the site Based on our knowledge and site observations, suitable habitat for the

PRELIMINARY HISTORIC AND ARCHAEOLOGICAL RESOURCES REVIEW
The State Historic Preservation Office (SHPO) was created by the United States government in
1966 under Section 101 of the National Historic Preservation Act (NHPA) The purposes of
SHPO include surveying and recognizing historic properties, reviewing nominations for
properties to be included in the National Register of Historic Places, reviewing undertakings for
the impact on the properties, and supporting federal organizations, state and local governments,
and the private sector
ECS was contracted to conduct a preliminary historic and archaeological resources review The
scope of work included a field reconnaissance to identify potential historic structures, a review of
aerial photographs, and a review of the SHPO Online GIS mapping
The site reconnaissance was conducted by ECS on November 6, 2014 The site is currently
located in a commercial area of Durham, Durham County, North Carolina Areas surrounding
the site are developed with commercial buildings Other areas consist of undeveloped, wooded
land
ECS reviewed aerial photographs of the site and Immediately surrounding properties for
evidence of past development The aerial photographs were obtained from Durham County GIS
and are dated 1994, 1999, 2005, and 2010. Aerial photographs dated prior to 1994 were not
available for review The ECS review is dependent on the quality and scale of the photographs
In the 1994 aerial photograph, the site appears wooded It appears that the Hamner Institute for
Health Services and associated structures are located on the parent parcel The adjacent
properties located to the northeast, southeast, and southwest appear to be developed with
commercial properties
In the 1999 aerial photograph, the site appears consistent with the previous 1994 aerial
Photograph. Significant changes were not noted in the vicinity of the site
In the 2005 aerial photograph, the site appears consistent with the previous 1999 aerial
photograph It- appears -that the previous- commercial - building is no longer present on the
southern adjacent property Other significant changes were not noted in the vicinity of the site
In the 2010 aerial photograph, the site appears consistent with the previous 2005 aerial
photograph It appears that a commercial building and associated parking lot have been
developed on the southern adjacent property Other significant changes were not noted in the
vicinity of the site
ECS reviewed the SHPO Online GIS Database (http: / /gisncdcr gov /hpoweb /) As depicted on

AGENCY CORRESPONDENCE
ECS composed letter requests addressed to the North Carolina Natural Heritage Program
(NHP), the USFWS, and the SHPO dated November 11, 2014, to determine If the subject site is
located in the immediate vicinity of registered sightings, habitats for endangered species, or
near significant architectural or archaeological resources
ECS received a response from Ms Allison Schwarz Weakley, Conservation Planner, with the
NHP on December 2, 2014, which states that the NHP does not have records of rare species,
important natural communities, significant natural heritage areas (SNHAs), or
conservation /managed lands within the proposed project area However, the letter states that
Douglass's Bittercress (Cardamine douglassn) is located approximately one mile south of the
proposed project area The letter states that the Douglass's Bittercress is located in the vicinity
of Northeast Creek floodplain, above Grandale Drive Additionally, the NHP database shows
that the Stirrup Iron Creek Marsh and Sloughs natural area are located approximately 0 6 miles
east of the site A copy of this correspondence is attached
ECS received a response from Mr John Ellis for Mr. Pete Benjamin, Field Supervisor, with
USFWS on December 12, 2014 The letter states that based on the information provided, and
other information available, it appears that the project as currently proposed will not impact
federally listed species or their habitats. Therefore, they believe that the requirements under
Section 7(a)(2) of the Act are fulfilled A copy of this correspondence is attached
ECS received a response from Ms Renee Gledhill - Earley, SHPO Representative, issued on
November 24, 2014 for the site Based on the information submitted, SHPO is not aware of

Dear Mr Smith,
ECS Carolinas, LLP (ECS) is pleased to provide our results of the Limited National
Environmental Policy Act (NEPA) Database Review conducted for the above - referenced site
Our services were provided in accordance with ECS Proposal No 06 -18137
BACKGROUND INFORMATION
The site is located at 6 Davis Drive in Durham, Durham County, North Carolina (Figures 1 and 2)
According to Durham County Online GIS Database, the site consists of two contiguous parcels that
are identified as Parcel Identification Numbers (PINS) 0748 -03 -12 -4785 (13 59- acres) and 0748-
03 -02 -7196 (42.4- acres) ECS understands that a portion of both parcels are to be evaluated
(approximately 2 acres in size) The parent parcel is currently developed with Hamner Institute for
Health Services and several additional structures No structures were observed on -site Other
areas on the site consist of undeveloped, wooded land Based on the United States Geological
Survey (USGS) Topographic Map, two unnamed tributaries to Burdene Creek are located along
the southeastern portion of the site
ECS was contracted to conduct a preliminary threatened and endangered species
determination and a preliminary historic and archaeological resources review for the site ECS
personnel conducted the field reconnaissance on November 6, 2014
PRELIMINARY THREATENED AND ENDANGERED SPECIES DETERMINATION
Congress passed the Endangered Species Act (ESA) in 1973 The purpose of the ESA is to
protect and recover imperiled species and the ecosystems upon which they depend It is
administered by the U S Fish and Wildlife Service ( USFWS) and the Commerce Department's
National Marine Fisheries Service (NMFS) The USFWS has primary responsibility for terrestrial
and freshwater organisms, while the responsibilities of NMFS are mainly marine wildlife
Under the ESA, species may be listed as either endangered or threatened "Endangered"
means a species is in danger of extinction throughout all or a significant portion of its range
"Threatened" means a species is likely to become endangered within the foreseeable future All
species of plants and animals, except pest insects, are eligible for listing as endangered or
threatened For the purposes of the ESA, Congress defined species to include subspecies,
varieties, and, for vertebrates, distinct population segments

Dear Mr Darnell
John E Skvarla, III
Secretary
Thank you for the opportunity to provide information from the North Carolina Natural Heritage Program
( NCNHP) database for the proposed project referenced above The NCNHP database does not show any
records for rare species, important natural communities, natural areas, or conservation /managed areas
within the proposed project area based on the maps submitted with your request for information
Within one mile of the proposed project area, the NCNHP database shows an element occurrence
record for the following rare species
* For status definitions, please see the Definitions document at http / /www ncnhp org /web /nhp /database- search
The occurrence record for Douglass's Bittercress is located southwest of the proposed project area, in
the vicinity of Northeast Creek floodplain above Grandale Drive
In addition, the NCNHP database shows that the Stirrup Iron Creek Marsh and Sloughs natural area is
located ca 0 6 miles east of the project area This natural area contains high - quality examples of
Piedmont /Mountain Semi- Permanent Impoundment (Shrub and Piedmont Marsh Subtypes) and Mesic
Mixed Hardwood Forest (Piedmont Subtype) natural communities
Please note that although the NCNHP database may not show records for rare species within the
proposed project area, it does not necessarily mean that they are not present, it may simply mean that
the area has not been surveyed Occurrences of rare species documented within one mile of the
proposed project area increase the likelihood that these species may be present within the project area
if suitable habitat exists The use of Natural Heritage Program data should not be substituted for actual
field surveys if needed, particularly if the project area contains suitable habitat for rare species

Re: Hamner Institute for Health Services- Durham County, NC
Dear Mr. Darnell:
This letter is to inform you that a list of all federally - protected endangered and threatened species
with known occurrences in North Carolina is now available on the U.S. Fish and Wildlife
Service's (Service) web page at http- / /-vvww fws gov /raleigh Therefore, if you have projects that
occur within the Raleigh Field Office's area of responsibility (see attached county list), you no
longer need to contact the Raleigh Field Office for a list of federally - protected species.
Our web page contains a complete and frequently updated list of all endangered and threatened
species protected by the provisions of the Endangered Species Act of 1973, as amended (I 6
U.S.C. 1531 et seq.)(Act), and a list of federal species of concern' that are known to occur in
each county in North Carolina.
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
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.
I The term "federal species of concern" refers to those species which the Service believes might be in need of
concentrated conservation actions. Federal species of concern receive no legal protection and then designation does
not necessarily imply that the species H ill eventually be proposed for listing as a tederall) endangered of threatened
species However, we recommend that all practicable measures betaken to avoid or minimize adverse ini pacts to
federal species of concern

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.
With regard to the above - referenced project, we offer the following remarks. Our comments are
submitted pursuant to, and in accordance with, provisions of the Endangered Species Act.
Based on the information provided and other information available, it appears that the proposed
action is not likely to adversely affect any federally- I isted endangered or threatened species, their
formally designated critical habitat, or species currently proposed for listing; under the Act at
these sites. We believe that the requirements of section 7(a)(2) of the Act have been satisfied for
your project. Please remember that obligations under section 7 consultation must be
reconsidered if: (1) new information reveals impacts of this identified action that may affect
listed species or critical habitat in a manner not previously considered; (2) this action is
subsequently modified in a manner that was not considered in this review; or, (3) a new species
is listed or critical habitat determined that may be affected by the identified action.
However, the Service is concerned about the potential impacts the proposed action might have
on aquatic species. Aquatic resources are highly susceptible to sedimentation Therefore. we
recommend that all practicable measures be taken to avoid adverse impacts to aquatic species,
including implementing directional boring methods and stringent sediment and erosion control
measures. An erosion and sedimentation control plan should be submitted to and approved by
the North Carolina Division of Land Resources, Land Quality Section prior to construction.
Erosion and sedimentation controls should be installed and maintained between the construction
site and any nearby down - gradient surface waters. In addition, we recommend maintaining
natural, vegetated buffers on all streams and creeks adjacent to the project site.
The North Carolina Wildlife Resources Commission has developed a Guidance Memorandum (a
copy can be found on our website at (http: / /www.fws.gov /raleigh) to address and mitigate
secondary and cumulative impacts to aquatic and terrestrial wildlife resources and water quality
We recommend that you consider this document in the development of your projects and in
completing an initiation package for consultation (if necessary).

We hope you find our web page useful and informative and that following the process described
above will reduce the time required, and eliminate the need, for general correspondence for
species' lists. If you have any questions or comments, please contact John Ellis of this office at

Re: Stormwater Collection Systems Plan Approval
6 Davis Drive — Hamner Institutes
DRB Number D1400055
Durham County Stormwater Project #SW -1408
Dear Mr Sherrill
On October 27, 2014, we received a stormwater construction drawing package submittal
package for the 6 Davis Drive project located at 6 Davis Dr, Durham, NC This construction
drawing set is approved by this office on December 3, 2014 Enclosed is a copy of the plans
and calculations, stamped approved by this office
The approved stormwater collection system consists of
1 Installation of a wet detention facility with a design permanent pool volume of
13,589 CF
2 Installation of a bio- retention facility with a design volume of 7,603 CF
3 Installation of a bio- retention facility with a design volume of 1,928 CF.
4 Installation of a bio- retention facility with a design volume of 6,165 CF
Our office will issue a Stormwater Operation and Maintenance Permit for the stormwater
control measures after the following are completed
1 The stormwater system is constructed and final construction inspected by a registered
professional engineer, a registered land surveyor, or a registered landscape architect A
signed and sealed copy of the inspection report must be submitted to this office
2 The final As -Built Plans sealed and signed by a registered professional engineer, a
registered land surveyor, or a registered landscape architect must be submitted
3 An operation and maintenance plan sealed and signed by a registered professional
engineer, a registered land surveyor, or a registered landscape architect must be
submitted
4 An operation and maintenance agreement signed and notarized by the property owner
This will be drafted near the end of the project.

An improvement security must be provided to our office in accordance with Ordinance
Section 14- 155(e) Our calculations indicate a performance bond in the amount of
$56,106 64 is necessary to ensure construction, and continuing operation, maintenance
and inspection of the facilities. Performance bond forms and information can be found
on the Durham County Engineering / S &E Webpage If you believe this bond amount is
incorrect please contact me See Attached
Please feel free to contact me if you have any questions pertaining to this approval at (919)
