Re: Brightwater Medical Complex - NWP 39 - Request for 401 Authorization
USACE AID#: 2008-01392
W&R Project Number - 02090050.10
Dear Mr. McMillan:
On behalf of the Harnett County Department of Public Utilities, we are requesting 401 authorization for
219 if of stream impacts and 0.35 acres of wetland impacts associated with the construction of the
Brightwater Medical Complex. The proposed wetland and stream impacts are necessary for construction of
the internal access roads and associated infrastructure. There are no wetland and/or stream impacts
proposed for lot fill.
The project is approximately 129 acres, and is located southeast of the intersection of US Hwy 401 and
Matthews Road, at Latitude 35.423617°N, and Longitude 78.812361°W, in Lillington, Harnett County
County, North Carolina. The project is located in the Cape River Basin and surface waters on-site flow
into Neills Creek, a tributary to the Cape Fear River. The Water Quality Classification for the Cape Fear
River is "WS-IV", the Stream Index Number is: 18-16-(0.7), and the Cataloging Unit for the site is
03030004.
Project Purpose
The proposed project consists of a mixed-use medical complex that will contain a hospital, medical
treatment offices, medical research facilities, a hotel and mixed-use retail/commercial area. The goal of the
project is to provide a self-supporting medical complex that will contain all services needed for the patients,
families of the patients and medical staff onsite.
The proposed hotel will provide onsite lodging for the families of patients during an extended stay in the
hospital. The mixed-use retail/commercial will contain a pharmacy (CVS, Kerr Drugs, etc), office space
and restaurants. The purpose of the mixed-use retail is to provide services needed by medical staff, patients
and families of patients within the proposed project.
The project has been designed to provide interconnectivity within the development so that medical staff,
patients, employees, etc can travel within the site to have lunch, pick up a prescription, and attend doctor
appointments without having to travel on US Hwy 401 of NC Hwy 210, thereby making it safer for patients
and staff to move about the complex. This will help to prevent congestion on US Hwy 401 and NC Hwy
210 as a result of traffic within the medical complex. The interconnect ivity of the site is also critical for
allowing ease of travel for medical staff and emergency medical personnel. By having multiple access
points to the main roads within the medical complex, medical personnel will be able to respond more
quickly to medical emergencies.
The proposed project represents a major economic impact on Lillington, as well as Harnett County and the
surrounding counties. The proposed Brightwater Medical Complex will provide 500+ jobs, including 100+
jobs directly in the medical field. The economic impact of this project spans from the jobs created for the
initial construction of the roads and infrastructure to the jobs created to run the retail/commercial
businesses. A letter from Mr. N. Johnson Tilghman, Chairman of the Harnett Forward Together

Committee, explaining the economic impact of the proposed project has been provided as an Appendix to
this application.
Project History
Wetlands were delineated by Maycock Environmental and the wetland survey was signed by Ronnie Smith
with the Corps of Engineers on November 12, 2008. A copy of the signed wetland survey has been
provided as an Appendix to this application.
While conducting a site review of the proposed stream crossings, a mapping error was identified on the
signed wetland survey prepared by Enoch Engineering, P.A. As a result of the mapping error, Encoch
Engineering, P.A. field surveyed the stream locations within the proposed road crossing alignments. The
Corps of Engineers was notified of the mapping errors on the signed wetland survey, and the Applicant is
in the process of revising the wetland survey for verification and signature. Ms. Crystal Amschler with the
Corps conducted a site review to verify the inaccurate stream locations. Due to the short time frames
needed to meet the conditions of the Federal Grants authorized for this project, the final revision to the
wetland survey will be completed after the application review process has been completed. Please note, as
stated below, the impact totals were calculated based on the corrected survey, although the revised final
wetland surveys have not yet been sent to the Corps office for signature.
The proposed wetland and stream impacts were calculated based on the accurate field surveyed location of
the streams and wetlands within the proposed road crossing alignments as provided by Enoch Engineers,
P.A. A copy of the revised field surveyed stream and wetland location has been provided as an Appendix
to this application. W&R has coordinated with the Corps of Engineers and has reached an agreement to
permit the proposed impacts based on the accurate field surveyed locations of the wetlands and streams,
with the understanding that the entire wetland survey would ultimately be revised and re-submitted to the
Corps of Engineers.
The Corps of Engineers issued a NWP 39 for the proposed project on February 24, 2010. A copy of the
Corps NWP 39 has been provided as an Appendix to this application.
Avoidance and Minimization
Prior to the design of the proposed project, the applicant requested that a detailed wetland delineation be
conducted so that impacts to wetlands and streams could be minimized.
In the original site plans, the project would have resulted in 300+ if of stream impacts and 0.5+ acres of
wetland impacts due to the road design and alignment. The proposed road crossings were revised to reduce
the proposed impacts to 219 if of stream impacts and 0.35 acres of wetland impacts. The alignment of the
roads was shifted in order to reduce stream and wetland impacts. The roads were designed to the minimum
width and radii allowable, while still allowing for higher speeds necessary for emergency vehicles to
navigate the site during an emergency. These revisions also included the use of retaining walls to stabilize
fill and reduce the overall footprint of road crossings at Impact Areas C, D and E. Also, bottomless arch
culverts were utilized to avoid stream impacts as Impact Areas B and D. The use of a bottomless culvert
for the road crossing at Area B eliminated the need for stream impacts entirely.
Stormwater Management Plan
The applicant proposes a combination of wet/dry detention ponds that will provide 85% TSS removal, as
per DWQ guidelines. Please note that the stormwater plans have only been finalized for Phase I of the
project. As future Phases are developed, the applicant will submit the stormwater plans under separate
cover for review by DWQ. We are requesting a conditional Stormwater Permit, stating that future

phases/impacts will not be constructed until the SW plans have been reviewed and approved by the NC-
DWQ.
A copy of the Stormwater Management Report has been provided as an Appendix to the PCN.
Mitigation
The proposed mitigation for 219 if of stream impacts and 0.33 acres of wetland impacts will consist of a
combination of offsite preservation and the purchase of mitigation from the Ecosystem Enhancement
Program (EEP).
The offsite preservation will consist of the preservation of 9,170 if of Anderson Creek and 53.1 acres of
adjacent buffer extending 200 if from Anderson Creek within the Anderson Creek Park, located on Nursery
Road in Lillington, Harnett County. The preserved buffer contains approximately 42 acres of wetlands.
The proposed offsite preservation was approved by the Corps of Engineers and was deemed sufficient to
justify a 1:1 ratio for the purchase of stream and wetland mitigation from EEP.
The purchase of stream and wetland mitigation from EEP will be provided in Phases as identified on the
attached phased site plan and in the Mitigation Table below.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The proposed project has been designed to avoid and minimize wetland impacts to the greatest extent possible. The initial
plans for the proposed project would have resulted in 300+ If of stream impacts and 0.5+ acres of wetland impacts in order to
facilitate development of the onsite uplands. Through multiple design modifications to the site plan, the proposed site plan will
result in 219 If of stream impacts and 0.35 acres of wetland impacts. The revisions to the site plan include shifting the
alignment of the road crossings, construction of retaining walls to stabilize road fill and installation of bottomless arch culverts
to minimize stream impacts.
All proposed wetland and stream impacts will occur as a result of construction of the access roads to facilitate development of
the onsite uplands and access of the site. Please note that there are no wetland/stream impacts proposed for lot fill. All roads
have been designed to meet the minimum width and radii standards while allowing for the higher speeds necessary for
emergency vehicles to navigate the site during an emergency. All proposed road crossings were designed at the narrowest
point of the wetlands and streams where crossings were needed to access onsite uplands for construction.
In order to minimize wetland impacts, the road crossings at Impact Areas C, D and E have been designed to utilize retaining
walls to stabilize fill. By constructing retaining walls, wetland impacts that would occur from encroachment of back slopes
have been avoided.
The main access roads will be dedicated to NCDOT after construction is complete. Therefore, the roads have been designed
to NCDOT criteria. Specifically, NCDOT requires medians for roads approaching a traffic circle. The road crossing at Impact
Area C was designed to meet NCDOT median requirement, while minimizing wetland impacts through the use of retaining
walls.
Wetland impacts at Impact Area A2 will result from construction of Brightwater Drive and placement of rip-rap below the
stormwater outfall for the hospital site stormwater management system. The rip-rap is necessary to reduce the velocity of out
falling stormwater, providing diffuse flow into the wetlands and preventing erosion and sedimentation of downstream wetlands.
In order to minimize stream impacts, the project has been designed to install bottomless arch culverts at Impact Areas B and
D to avoid stream impacts at these crossings. The bottomless arch culverts will span the entire width of the stream,
preventing any disturbance to the stream bed. By installing a bottomless arch culvert at Area B, the proposed road crossing
will not require any impacts to provide access to the proposed development.
At Impact Area E, the road crossing has been designed with two 60" culverts beneath the road. By installing the culverts
beneath the road, the hydrologic connection between the wetlands on either side of the road will be maintained in the post
development condition. The culverts will convey surface water freely beneath the road during storm events, maintaining the
natural hydrologic regime of the onsite wetlands.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The road crossings at Impact Areas A and C have been designed to install the culverts below the natural grade of the stream
bed to allow for passage of aquatic life during periods of low flow. The stream bed will be armored with rip-rap above and
below the culverts to dissipate energy and prevent scouring and erosion of the stream bed as required by Department of Land
Quality for erosion control measures. The placement of rip-rap upstream of the culvert will prevent undercutting of the culvert
from stream flow and will prevent repeated disturbance of the stream from frequent maintenance of the culvert to repair the
undercutting,
The road crossings at Impact Areas B and D have been designed to avoid stream impacts through use of bottomless culverts
which will span the entire width of the stream, preventing impacts to the stream bed from installation of a standard round
culvert. The bottomless arch culvert shall be built to span the creek with ample width to reduce scour. In the case of the
bottomless culvert to be built at the end of Crested Iris Drive in a future phase, preliminary hydraulic calculations would
indicate the need for a 19' span and 6' of clearance above the creek bed. This pipe arch would be set in continuous
concrete footings which in turn will be placed on concrete or steel piles that will bear directly on rock. Soil borings for a
site adjacent to Crested Iris Drive and opposite the stream, indicate a rock depth of 5' to 8'. A bottomless culvert will
be less than half the cost of a bridge structure and will be structurally sound given the ability to bear on shallow rock.
Since NC DOT does not allow the use of bottomless culverts for NC DOT maintained roads, the bottomless culverts could only
be utilized for the secondary access roads to minimize stream impacts.
Page 7 of 12
PCN Form - Version 1.3 December 10, 2008 Version
The road crossings at Impact Areas C, D and E have been designed to utilize retaining walls to stabilize fill. By using retaining
walls, wetland impacts that would occur from encroachment of back slopes have been avoided.
Also, the installation of the water main to the proposed project, located at Impact Area C, will be installed through a directional
bore beneath the wetlands and stream. The directional bore will enter and exit entirely within uplands, avoiding wetland
impacts necessary for traditional trench and backfill methods of installing water lines.
During construction, silt fencing will be placed around all construction limits to prevent sediment from escaping the project site
and entering the onsite wetlands and streams.

Harnett County has faced many challenges in the last decade --- the loss of our textile industries, including one
of the largest industrial closings in North Carolina, as well as major changes in agriculture. In response, the
Harnett County leaders and volunteers have worked diligently to develop and implement initiatives to counter
these devastating economic setbacks and to prepare Harnett County to succeed in a new, knowledge-based
economy.
Much has been done to prepare Harnett County to step up its role in this new economy, and the Brightwater
Science and Technology Campus will push us a giant step forward towards securing a more diverse economic
base and employment for our residents.
The ongoing challenge to meeting this goal is to continually evolve and improve one's community product as
industry needs change. Brightwater is such a product. It marries our state's science and technology initiatives
with Harnett County's own resources to attract these businesses along with the knowledge workers they need.
Within the last several years, North Carolina has ranked 7th highest among U.S. states for funding from the
National Institutes of Health (NIH) and 15th among states receiving National Science Foundation (NSF)
funding-funds totaling $2.7 billion. However, without a product on which to focus these dollars, Harnett
County cannot compete.
It is here that the infrastructure is so important to Brightwater's success. This infrastructure is important on
several fronts. First, roads, water and sewer are necessary to build the new 50-bed hospital of Harnett Health
System and create over 100 well-paying healthcare jobs there. In addition, just as infrastructure is key to the
hospital, the hospital is key to the future of the park. Our research and experience with the partnership show
that businesses will simply not relocate to areas without access to health care. A first class healthcare facility
will become an important draw for site-selection decisions in any industry.
Brightwater's economic impact can also spill over into other rural counties. It accommodates a mix of indus-
trial, education, retail and healthcare businesses to create a diversified employment base. People employed in
construction trades will find new opportunities not only as the 128-acre campus fills out, but also to serve new
businesses that grow there to support the campus and those working nearby.
I would also like to share another fact that differentiates Harnett County's project from many other industrial
sites now available. Site plans for Brightwater prioritize the need to enhance the regional beauty of the area,
and so contribute to quality of life issues that we know to be important to well-educated workers. This speaks
not only to the county's focus on raising standards of living but also on improving quality of life for all the re-
gion's citizens.
I have included two exhibits to the correspondence. The first is a narrative further describing the Brightwater
project. The second is a summary of grants received on this project and the very specific time frames within
which we must work to secure the funds. Please note that all grants have been given in anticipation of the hos-
pital's construction commencing in the spring of 2010, opening in summer 2012. Please also note that the
there is a condition required by the US Department of Commerce/ Economic Development Administration,
who provided a $1,000,000 grant, that the project not be advertised for bid until we provide evidence that a
404 Permit has been obtained.
I appreciate your support of our efforts and encourage your approval and support as well. With your support,
Harnett County can begin soon to leverage the significant potential inherent in the new Brightwater Science
and Technology campus.
Sincerely,

N. Johnson Tilghman, Chairman

Harnett County Exhibit 1 September 11, 2009
The Briahtwater Science and Technoloov Campus
The joint project between the Harnett Forward Together Committee (HFTC), Harnett County and
East Central Water and Sewer District will involve the construction of water, sewer and road
(including drainage) improvements to serve the 128 acre Brightwater Science and Technology
Campus. Harnett Health Services (HHS) is the anchor business, having committed to locate a
$50.6 million hospital in the park. Campbell University and Central Carolina Community College,
in partnership with HFTC, is planning the location of a pharmaceutical research/education facility
at the Campus. The Campus, when fully developed, will contain a projected 626,660 sq. ft.
technology/research, 87,600 sq. ft. office/retail and 85,000 sq. ft. hospital space. The project will
create 500 (+) technology/life science and healthcare jobs on the campus and the potential
clustering of these industries in additional locations within Harnett County, a rural tobacco and
textile dependent county.
The primary geographic area served by the project is Harnett County. The employment
opportunities created by the project will serve 18 year old unemployed and underemployed
Harnett County residents and residents having to out-commute for economic opportunities.
Historically the number of employment opportunities created by Harnett County's economy has
been significantly less than its workforce. The total number of jobs provided by Harnett County
employers represented 49.2% of the County's employed workforce in 1990; 55.9% of its 2000
employed workforce; and 52.9% of its 2006 employed workforce.
Not only does Harnett County's economy display a significant disparity between the number of
jobs created within the County to its workforce, it also exhibits a pronounced disparity in average
wages paid by its employers to wages paid in other counties. For the year 2006, the total average
wage paid by Harnett County employers was 67.2%, 76% and 67.3% of the total average wage
paid by employers in the Regional Partnership, State and Wake County. Harnett County's
Manufacturing sector's annual wage ($32,822.79) for this period was 51.5%, 73.1 % and 56.5% of
the Regional Partnership, State and Wake County average manufacturing wage, Even though
Harnett County's Manufacturing sector average wage is significantly below comparison areas, it
represents the second highest average wage ($32,822 - 2,854 workers) in the County,
surpassed only by the Information sector ($35,134 - 403 workers).
In addition to the preceding structural problems, Harnett County's economic base is undergoing a
severe restructuring. Manufacturing sector employment as a percent of total employment
declined 43.48% between 1990 to 2006 (27.6% to 12.0%) as Service and Education/Health
Services sectors employment have increased 22% (63.7% to 77.75%) and 48.7% (18.9% to
28.11%).
Harnett County's economic base has not created a sufficient number of jobs within the county for
its workforce nor has its created average wages comparable to surrounding counties. These
conditions results in a high percentage of Harnett County workers out-commuting for economic
opportunities (60.5% out-commuted in 2000) and many of its residents finding employment in
Harnett County being underemployed.
The Brightwater Project will result in infrastructure being constructed to allow the location of
technology, healthcare and research facilities in the Brightwater Science and Technology
Campus. The advancement of these industry clusters within the park and throughout Harnett
County will create job opportunities whose wages and/or benefits will reduce underemployment
and the need of residents to have to out-commute for economic security.
The History
In response severe structural changes occurring within its manufacturing sector, HTFC in
partnership with the Harnett County Board of County Commissioners, contracted with Leak-
Harnett County Exhibit 1 September 11, 2009
Goforth to prepare an "Economic Development Assessment and Action Plan". This study
identified `Another prime location for industrial development with a high tec orientation is the
highway 421 corridor from Lillington to Buies Creek." as an area where the development of a park
with a biotechnology theme would be successful.
After discussions with Campbell University, Central Carolina Community College (CCCC) and
property owners, HFTC identified a 128 acre site on US 401 near Lillington to be developed as a
science and technology research campus. HFTC, through funds provided by the Harnett County
Board of County Commissioners, purchased this site in 2006 (Project Begin Date) for $5.7 million.
After acquiring the site, HFTC contracted with to develop a conceptual master plan for the park.
As the conceptual master plan was being developed, HFTC, Harnett County Economic
Development Commission and Harnett County began negotiations with Harnett Health Systems
to locate a new hospital at the park. It continued dialogue with Campbell University concerning
the establishment of a pharmaceutical research/Education facility to promote/support the location
of technology companies at the park and throughout the County.
The project has been developed and will be implemented through a partnership consisting of the
Harnett Forward Together Committee, Harnett County Economic Development Commission,
Harnett County, East Central Water and Sewer District, Harnett Health Systems, Campbell
University and Central Carolina Community College.
The Future
HFTC in partnership with the Harnett County Economic Development Commission will directly
market the project to its build-out. The Harnett County Economic Development Commission is a
Harnett County department created by the Harnett County Board of Commissioners and funded
through its annual budget process.
The Harnett County Economic Development Commission's budget contains funds to market
parks and properties owned by HFTC.
HFTC and the Harnett County Economic Development Commission will utilize the Research
Triangle Partnership, NC Department of Commerce, Progress Energy, etc. in its marketing
activities.
• HFTC working directly with developers to finance and construct office/retail space and with
developers and individual businesses to construct biotechnology manufacturing/research
space within the park.
• Harnett Health System's hospital and its planned activities create 100 new jobs/investments
in the park and indirectly through adjoining location of doctors, dentist, etc. locating in park
offices and healthcare retail space.
• Campbell University and Central Carolina Community College's envisioned
Education/Research Facility and Family Nurse Practitioner Program will promote/support the
successful build-out of the project.

BRIGHTWATER SCIENCE AND TECHNOLOGY PARK
STORMWATER MANAGEMENT REPORT
HARNETT COUNTY, NORTH CAROLINA
INTRODUCTION
Brightwater Science and Technology Park is a planned business development located in Harnett
County. The proposed 128-acre development will have a mix of office, institutional and retail uses
including the proposed Harnett Health Systems Hospital. The site lies directly across US401 from the
Harnett County Courthouse complex and is bounded to the west by the Matthews Road and to the
south by US401. The main entrance to the site will align with McKinney Parkway on US401. The site
lies within a WS-IV-PA watershed classification and is subject to Harnett County Water Supply
Watershed Management and Protection Ordinance. The purpose of this report is to establish the
minimum criteria for stormwater compliance that will apply to the initial infrastructure development
and the overall proposed stormwater management approach to meet the requirements.
STORMWATER MANAGEMENT REQUIREMENTS
Because the proposed development is within the Cape Fear River Basin, the site must meet the
requirements of the Harnett County Water Supply Watershed Management and Protection
Ordinance. This ordinance states: "Exception for Non-Residential Uses: Up to so% of the protected
area may be developed for non-residential uses to seventy percent (70%) built-upon area on a
project by project basis. For the purpose of calculating built-upon area, total project area shall
include total acreage in the tract on which the project is to be developed." This project has been
designated for high intensity use as part of this exception. In reference to stream buffers this
ordinance requires: "a minimum of a zoo hundred (soo) foot vegetative buffer for development
activities that exceed low density standards as established in this ordinance is required along all
perennial waters indicated on the most recent versions of the U.S.G.S 1:24,000 (7.5minute) scale
topographic maps, otherwise a minimum of thirty (30) foot buffer is required."
STORMWATER MANAGEMENT APPROACH
To meet the requirements of the Harnett County Water Supply Watershed Management and
Protection Ordinance, streams within the site will be subject to 30' stream buffers as no perennial
streams are indicated based on current U.S.G.S. mapping. In addition, an overall stormwater
management plan is proposed that will treat the runoff form the first one inch of rainfall and remove
a minimum ofeighty-five percent (859/6) oftotal suspended solids (TSS). Retention ponds are
proposed as the primary best management practice devices. Thirty foot filter strips will be required
at the release points for the first flush volume or the retention ponds shall be designed to treat for
ninety percent (go%) TSS removal.
Delineation of the drainage area to each BMP was based on existing terrain and a preliminary
estimate of storm drainage design. The impervious area for each drainage area was estimated
based on the preliminary illustrative master plan. To determine the surface area required for each
BMP, the volume of run-off created by one inch of rainfall (the "first flush") was calculated for the
drainage area. To calculate this water quality volume the Simple Method was used, as described in
the DWQ BMP Manual. This method uses a run-off coefficient to calculate the volume of run-off
given a depth of rainfall. The run-off coefficient is determined based on the percent imperviousness
of the drainage area. The minimum surface area necessary for the wet ponds was determined as
directed in the NC DWQ BMP manual.
The first phase of construction will be to establish the road network and infrastructure to support the
subsequent development of individual parcels. After completion of the various phases of grading
including the phase one road network, the wet ponds designed to treat each phase or parcel shall
be fully operational. All phases and parcels shall meet this stormwater management approach and
submit to NCDENR DWQ for approval prior to the start of construction.
