APPROVAL of Neuse River Buffer Rule (15A NCAC 02B .0233) AUTHORIZATION CERTIFICATE,
DWQ Express Review Program
Dear Mr. Solheim:
You have our approval, in accordance with 15A NCAC 02B .0233 and any conditions listed below, to impact
approximately 9000 ft2 or 0.21 acres of Zone 2 of the protected riparian buffers for the purpose of constructing the
stormwater pipe in the 20' wide drainage easement of the adjoining properties as described within your application dated
February 12, 2004. In addition, you should obtain or otherwise comply with any other required federal, state or local
permits before you go ahead with your project including (but not limited to) Erosion and Sediment Control and Non-
discharge and/or Water Supply Watershed regulations.
This approval is only valid for the purpose and design that you described in your application. If you change your project,
you must notify us and you may be required to send us a new application. If the property is sold, the new owner must be
given a copy of this authorization and approval letter and is thereby responsible for complying with all conditions. For this
approval to be valid, you must follow the conditions listed below.
Conditions:
1. Diffuse Flow
An additional condition is that all stormwater shall be directed as diffuse flow at non-erosive velocities through the
protected stream buffers along the drainage easement and will not re-concentrate before discharging into the stream
as identified within 15A NCAC 213 .0233(5).
2. Protective Fencing
The outside buffer boundary and along the construction corridor within this boundary approved under this
authorization shall be clearly marked with orange fencing for the areas that have been approved to infringe within the
buffer prior to any land disturbing activities to ensure compliance with 15A NCAC 213.0233.
3. Certificate of Completion
Upon completion of all work approved within this authorization, and any subsequent modifications, the applicant is
required to return the attached certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water
Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650.

Any disputes over determinations regarding this Authorization Certificate (associated with the approved buffer impacts)
shall be referred in writing to the Director for a decision. The Director's decision is subject to review as provided in
Articles 3 and 4 of G.S. 150B. This Authorization Certificate shall expire five (5) years from the date of this letter.
This letter completes the review of the "No Practical Alternatives" determination under 15A NCAC 2B.0233. If you have
any questions or would like a copy of the buffer rules, please call [phone]. This letter does not authorize any
impacts to either Waters of the United States or Waters of the State. Please contact the US Army Corps of Engineers
(USACE) or NC Division of Water Quality (DWQ) if any impacts are proposed to either of these waters.

Re: NC Specialty Hospitals Site - Durham, NC F?G? 1 GJ 0A
Buffer Approval Request, Express Review Program
Supplemental information Dear John and Debbie:

Thank you for meeting us on site yesterday! I know we are all anxious to get this approval
process completed.
At the site, we provided you with 3 copies of a revised site plan showing no impervious area
impact to any portion of the riparian buffer zone on this site. As you are aware, we were able to
reconfigure the access road to move it out of the buffer. We will, however, impact Zone 2 in two
different areas:
1) Adjacent to the access road. Buffer disturbance in this area is necessary to get the
grade to construct the access road. No impervious surfaces will be placed in either zone
of the buffer.
2) Down-gradient from this site for stormwater piping. Buffer disturbance in this area is
across two adjoining properties in a 20' wide drainage easement. The drainage
easement encompasses most of Zone 2 of the buffer along these properties. The
disturbance in this area will only be related to the installation of the stormwater piping,
and the area will be revegetated immediately after construction.
Please accept this letter as a request to remove our application for a minor buffer variance and
to request buffer approval for the impact on this site and the adjoining property. This impact is
necessary to construct the access road and pipe stormwater from our site to the downstream
pond. Total buffer disturbance/impact is approximately 9900 ft2.
I am including a copy of a revised PCN for this site, noting the buffer impact changes. I will fax
a copy of the signature page as soon as we have Dennis' signature.
As noted in the field, we would be very appreciative of a favorable review and comments in
writing today, if possible.
Sincerely,
Beth Chesson

Pre-Construction Notification (PCN) Application Form
For Section 404 and/or Section 10 Nationwide, Regional and General Permits, Section 401
General Water Quality.Certifications, and Riparian Buffer and Watershed Buffer Rules
This form is to be used for projects qualifying for any of the U.S. Army Corps of Engineers' (USACE)
Nationwide, Regional or General Permits as required by Section 404 of the Clean Water Act and/or
Section 10 of the Rivers and Harbors Act, and for the North Carolina Division of Water Quality's
(DWQ) associated General 401 Water Quality Certifications. This form is also to be used for any
project requiring approval under any Riparian Buffer Rules implemented by the N.C. Division of Water
Quality. This form should not be used if you are requesting an Individual 404 Permit or Individual 401
Water Quality Certification. The USACE Individual Permit application form is available online at
http://www.saw.usace.army.mil/wetlands/Perm-app.htm.
The USACE is the lead regulatory agency. To review the requirements for the use of Nationwide,
Regional or General permits, and to determine which permit applies to your project, please go to the
USACE website at http://www.saw.usace.army.mil/wetlands/regtour.htm, or contact one of the field
offices listed on page 3 of this application. The website also lists the responsible project manager for
each county in North Carolina and provides additional information regarding the identification and
regulation of wetlands and waters of the U.S.
The DWQ issues a corresponding Certification (General or Individual), and cannot tell the applicant
which 401 Certification will apply until the 404 Permit type has been determined by the USACE.
Applicants are encouraged to visit DWQ's 401/Wetlands Unit website at
http://h2o.enr.state.nc.us/ncwetlands to read about current requirements for the 401 Water Quality
Certification Program and to determine whether or not Riparian Buffer Rules are applicable. The
applicant is also advised to read the full text of the General Certification (GC) matching the specific 404
Permit requested. In some cases, written approval for General Certifications is not required, provided
that the applicant adheres to all conditions of the GC. Applicants lacking access to the internet should
contact DWQ's Central Office in Raleigh at [phone].
Trout Waters, Coordination - Special coordination with the North Carolina Wildlife Resources
Commission (NCWRC) is required for projects occurring in any of North Carolina's twenty-five
counties that contain trout waters. In such cases, the applicant should contact the appropriate NCWRC
regional coordinator (listed by county on page 4 of this application) prior to submittal of the application.
Page 1 of 14
Coastal Area Management Act (CAMA) Coordination - If the project occurs in any of North Carolina's
twenty coastal counties (listed on page 4) the applicant should contact the North Carolina Division of
Coastal Management (DCM). DCM will determine whether or not the project is within a designated
Area of Environmental Concern, in which case DCM will act as the lead permitting agency. In such
cases, DCM will require a CAMA Permit and will coordinate the 404/401 Permits.
The applicant may also choose to coordinate with the United States Fish and Wildlife Service to ensure
that the proposed project will have no impact upon any endangered or threatened species or critical
habitat as regulated by the Endangered Species Act, and the State Historic Preservation Office, North
Carolina Department of Cultural Resources to ensure that the proposed project will have no impact upon
any properties listed or eligible for listing on the National Register of Historic Places. Compliance with
these regulations is required to be eligible for any Department of the Army permit. The addresses for
both agencies are listed on page 3 of this application.
USACE Permits - Submit one copy of this form, along with supporting narratives, maps, data forms,
photos, etc. to the applicable USACE Regulatory Field Office. Upon receipt of an application, the
USACE will determine if the application is complete as soon as possible, not to exceed 30 days. This
PCN form is designed for the convenience of the applicant to address information needs for all USACE
Nationwide, Regional or General permits, as well as information required for State authorizations,
certifications, and coordination. Fully providing the information requested on this form will result in a
complete application for any of the USACE Nationwide, Regional or General permits. To review the
minimum amount of information that must be provided for a complete PCN for each USACE
Nationwide permit, see Condition 13, 65 Fed. Reg. 12893 (March 9, 2000), available at
http://www.saw.usace.army.mil/wetlands/nwpfinalFedReg_pdf. Processing times vary by permit and
begin once the application has been determined to be complete. Please contact the appropriate
regulatory field office for specific answers to permit processing periods.
401 Water Quality Certification or Buffer Rules - All information is required unless otherwise stated
as optional. Incomplete applications will be returned. Submit seven collated copies of all USACE
Permit materials to the Division of Water Quality, 401/Wetlands Unit, 1650 Mail Service Center,
Raleigh, NC, 27699-1650. If written approval is required or specifically requested for a 401
Certification, then a non-refundable application fee is required. In brief, if project impacts include less
than one acre of cumulative wetland/water impacts and less than 150 feet cumulative impacts to
streams, then a fee of $200 is required. If either of these thresholds is exceeded, then a fee of $475 is
required. A check made out to the North Carolina Division of Water Quality, with the specific name of
the project or applicant identified, should be stapled to the front of the application package. For more
information, see the DWQ website at http://h2o.ehnr.state.nc.us/ncwetlands/fees.html. The fee must be
attached with the application unless the applicant is a federal agency in which case the check may be
issued from a separate office. In such cases, the project must be identifiable on the U.S. Treasury check
so that it can be credited to the appropriate project. If written approval is sought solely for Buffer Rules,
the application fee does not apply, and the applicant should clearly state (in a cover letter) that only
Buffer Rule approval is sought in writing. Wetlands or waters of the U.S. may not be impacted prior to
issuance or waiver of a Section 401 Water Quality Certification. Upon receipt of a complete application
for a 401 Certification, the Division of Water Quality has 60 days to prepare a written response to the
applicant. This may include a 401 Certification, an on-hold letter pending receipt of additional
requested information, or denial.

7. Nearest body of water (stream/river/sound/ocean/lake): UT to Eno River
8. River Basin: Neuse River Basin
Page 6 of 14
(Note - this must be one of North Carolina's seventeen designated major river basins. The
River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.)
9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: During site preparation. the subdivision developer placed fill
material from other lots on this lot. Sparse vegetation currently exists at the site. Grading for
this site plan has not yet begun. Land use surrounding the site is mostly urban. This site is
situated within a commercial subdivision.
10. Describe the overall project in detail, including the type of equipment to be used: This
construction site is one tract (4.6 ac) within an overall commercial subdivision. It is going to
be developed as a hospital including parking lots. driveways, and landscaped areas. The
exact nature and extent of the construction equipment will be determined by the contractor,
but anticipated equipment includes: bulldozers, dump trucks, front-end loaders, and cement
trucks. Most heavy equipment will be restricted to outside the buffer zone. However, some
construction equipment will be utilized within Zone 2 of the buffer in order to get the site to
grade for the installation of the access road and to install the stoimvater pipe in the easement
on the adjoining property. No impervious surfaces are located within the buffer, and no
disturbance will be allowed in Zone 1 of the buffer.
11. Explain the pupose of the proposed work: The purpose of this project is to create a new
surgical center to replace an older hospital facility built in 1925 in another location within
Durham.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules.
In October 2003, Steve Mitchell with the DWQ Raleigh Regional Office evaluated the site for
the presence of a stream. He determined the stream feature within the tract was a stream and was
subject to the Neuse Buffer Rules. The DWQ Raleigh Regional Office project # is NBR03-263
and 282. Plans were developed to address Mr. Mitchell's concerns at the site, and a package was
submitted to him for approval of a minor buffer variance. On December 16, 2003, Mr. Mitchell
Page 7 of 14
issued a letter supporting the plans so the site developer could approach the Durham review
board for approval. Mr. Mitchell's letter is included.
An overview of the site conditions follows: The 4.6 acre site has been graded and filled with
approx. 20' of fill by subdivision developer in an effort to make the site more marketable.
Currently, it is cleared and grass covered. The fill material used is a variable composition of
claw, silty and sandy soil mixed with gravel, asphalt, concrete, brick and organics. Please see
the supplemental geotechnical report for more details. The stonnwater flow off the site is
currently 11.77 cfs based on a 10-year return event. After the planned construction is completed,
the stormwater flow off the site will be 22.53 cfs based on a 10-year return event. Please see the
supplemental stormwater plan for more details.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
At this time, future permit requests are not anticipated.
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, permanent
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must be shown on a
delineation map, whether or not impacts are proposed to these systems. Wetland and stream
evaluation and delineation forms should be included as appropriate. Photographs may be
included at the applicant's discretion. If this proposed impact is strictly for wetland or stream
mitigation, list and describe the impact in Section VIII below. If additional space is needed for
listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: We do not anticipate stream impacts.
Only impacts to Zone 2 of the buffer are anticipated. 2/11/04 9900 ft2 of Zone 2 of the
buffer will be affected by obtaining the grade necessary to construct the access road and the

* List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging,
flooding, drainage, bulkheads, etc.
5. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.):
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):
Size of watershed draining to pond: Expected pond surface area:
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
After discussions with Debbie Edwards and John Domey, the impervious surfaces have been
removed from the buffer. The only buffer impacts are in Zone 2 of the buffer. Minor Zone 2
impacts are anticipated adjacent to the access road. No impervious surfaces are to be placed in
the buffer; only cut and fill associated with grading the site for the access road is anticipated.
Buffer zone 2 on the adjacent property will be disturbed for the installation of the stormwater
pipe located in the drainage easement. Buffer zone impacts have been minimized.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
Page 10 of 14
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmgide.htm].
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Stream and buffer impacts requiring mitigation are not anticipated.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet):
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):
IX. Environmental Documentation (required by DWQ)
Does the project involve an expenditure of public (federal/state) funds or the use of public
(federal/state) land?
Yes ? No
Page 11 of 14
If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No ?
If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEPA or SEPA final approval letter.
Yes ? No ?
X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?
Yes ® No ? If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.
Zone* Impact
(square feet) Multiplier Required
Mitigation
1 0 3 0
2 9900 1.5 0
Total 9900 1.5 0
* Zone i extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or .0260.
Buffer mitigation is not required.
XI. Stormwater (required by DWQ)
Page 12 of 14
Describe impervious acreage (both existing and proposed) versus total acreage on the site.
Discuss stormwater controls proposed in order to protect surface waters and wetlands
downstream from the property.
Currently, there are no impervious surfaces on this tract (100% pervious). The proposed
impervious area is 2.5 ac of 4.6 ac (54% pervious). Stormwater from this site will not be
discharged into the buffer, so flow diffusion is not required. Instead, stormwater will be routed
through a culvert to a stormwater pond downstream that was previously approved by the Cites
Durham for the reduction of nitrogen for the entire commercial development. The pond provides
25% nitrogen reduction; NCSH paid the additional offset fee into the NCWRP. While the
stormwater culvert will be constructed in Zone 2 of the buffer, no impervious area will be
created in this area, and no impacts to Zone 1 are anticipated. See maps C3.01 and C3.02 and
stormwater site plan narrative.
Total acres=4.6 Total build-out impervious acres=2.48 Total area disturbed=3.8 ac. See map
C3.01.
XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
The sewage is discharged into an 8" sewer line and ties in to city sewer line. See map C.501
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application?
Yes ? No
XIV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
NCSH has been developing these plans since 1997. City approval schedules, Certificate of Need
schedules (required for hospitals), and environmental permitting schedules all have to be met.

Beth,
I have found a conflict with the issuance of the Neuse Buffer
Authorization that I said I could get to you tomorrow by 12:00. 1
cannot find a map in the application package that clearly indicates the
amount of disturbance of the stormwater pipe that is to be placed within
Zone 2. We need to know the amount of disturbance in square footage
the length of the pipe x the width of the construction corridor, in Zone
2). The existing Pre-Construction Notification (PCN) Application only
refers to the area where the road previously was placed. We need a
revised PCN along with a map representing this disturbance.
I may be able to still put the letter together for the approval with a
condition that you get the info. to me within "so many days", this will
have to be approved by John Dorney. But before I can put the
Authorization together, I NEED the square footage of impacts to Zone 2.
I will also need to know, within the PCN, the amount of buffer to be
replanted.
I'm sorry to throw this at you this late, I did try your cell phone and
could not get a hold of you. I should be in at 8:30 in the AM if you
need to talk to me, we are expecting a snow storm though. 919-733-9584

John, Debbie, and Bob,
Thanks so much for taking the time to conference call with me Friday. Hopefully, we can circumvent this
back and forth somewhat.
Here are the key points that I heard from Friday's meeting:
- Under the buffer rules, the 30% N reduction has to be provided for all portions of the site. We cannot
provide 60% reduction for one portion of the site and 20% reduction on the rest.
- We can utilize the pollutant reduction for the pond and add a BMP to the site to provide the full 30%
reduction. However, it is likely that the pond actually provides less than 25% reduction.
- If we remove the impervious area impacting Zone 2 of the buffer and we keep the stormwater pipe in Zone
2 of the buffer downgradient from the site, we do not have to provide additional stormwater quality treatment.
Fill slopes can be placed in Zone 2 of the buffer as long as they are vegetated. DWQ has already
determined that there is no practicable alternative to piping the stormwater in this manner.
- We can tie into the existing 72" pipe if we do not impact the buffer.
If we decide we can remove the impervious area from the buffer completely, what information do you need to
verify this?
We have a meeting set up for 1:00 pm on Feb 11 in Durham on the site at the corner of Ben Franklin and
William Penn. NCSH representatives will be in attendance, as well as AMEC, CFP and hopefully the City of
Durham. The goal is to review site conditions to discuss alternatives and deliver the additional information
needed to finish the buffer variance requirements.
Again, thanks for your time!

John and Debbie,
Before I can completely address the items listed in today's letter, I need clarification. I cannot address item 2 without
better understanding item 1.
Item 1: The previously submitted material in the PCN erroneously noted that the BMP was a wetland. I did not realize
that wet ponds are not approvable BMPs for the reduction of nitrogen. The Neuse Model Stormwater Program and the
NC BMP manual note that the N removal efficiency for wet ponds is 25%. That is less than the required 30%
reduction, so we paid into the Wetlands Restoration Program $4011 to offset the N reduction needed. Is this not an
acceptable alternative for the minor buffer variance?
Item 2: We can provide the calculations if the wet pond is acceptable.
This commercial subdivision has been in place for many years, as has the pond. Based upon conversations with
Durham staff (Paul Weibeke), the pond was built to address existing conditions within the drainage area outside of
Independence Park and full built out conditions inside the Park.
Please respond back via email or call me on my cell phone to discuss these issues so we can address your concerns.
Thanks,
Beth
ps. Debbie: Congrats on your new position!

CERTIFIED MAIL - RETURN RECEIPT REQUESTED
Mr. Dennis Solheim
NC Specialty Hospital of Durham. Inc.
1110 W. Main Street
Durham, NC 27701
Dear Mr. Solheim:
RE: NC Specialty Hospital
Durham County
DWQ # EXP 04-0039
Staff have reviewed your response dated January 30, 2004 (received February 2, 2004)
to our January 26, 2004 letter concerning permitting issues in relation to this project. As you
know, the original application was received by DWQ on January 13, 2004. Unfortunately, your
latest response does not address all of the questions in our January 30 letter and in fact, raises
additional questions. Please address the following questions with respect to stormwater
management from this site. Your response with respect to the location of the stormwater pipe
located in Zone 2 is acceptable to DWQ and we have concluded that this use is allowable under
the Neuse River buffer rules. However until the following stormwater questions are addressed,
we cannot complete permitting on this project and it will remain on-hold as incomplete.
1. Type of BMP - The Preconstruction application for this project clearly states that
the BMP that you propose to utilize for treatment of stormwater from this site is a
constructed wetland. However the design details provided in your submittal show
that the facility is a wet detention (or retention) pond. In the Neuse River basin
where approval under the Neuse River Buffer rules is needed, wet basins do not
provide sufficient nitrogen removal to satisfy the requirements of the Minor
Variance. Constructed wetlands, bioretention areas, diffuse flow through wooded
buffers, or dry basins followed by diffuse flow through wooded buffers do remove
sufficient nitrogen to meet these requirements. Therefore, the wet detention (or
retention) basin will not provide adequate treatment for the Minor Variance even if
it has been designed to meet DWQ standards. However if previous written DWQ
approval under the 401 Water Quality Certification Program was received for this
pond, then we may be able to accept its use for this Minor Variance. Please
address whether specific written approval was received from DWQ for the
construction of this pond under the auspices of a 401 Water Quality Certification
for this development.

1-877-623-6748
II. Design of the BMP - In our earlier letter, we asked whether the stormwater
management device was designed to meet DWQ design standards in DWQ's
stormwater manual. Your response was not clear. If you still intend to utilize this
BMP for stormwater treatment, please provide detailed calculations using the
worksheets provided in our design manual to demonstrate that this pond is sized
sufficiently to provide treatment as required. For instance, it is not clear whether
the pond is designed to treat the entire watershed draining to it according to
DWQ's design manual or whether it is just designed to treat new development in
the Independence Park development. This fact is especially important since the
pond is located on a stream channel - therefore, it must be designed to handle all
of the stormwater from its entire watershed. The HEC-1 analysis that was
provided appears to show that the pond will serve to reduce storm peak flow but
does not describe the water quality ability of the BMP.
III. Buffer Mitigation - Upon review of your additional submittal, the area to be
planted with trees along the stream may provide sufficient compensatory buffer
mitigation for the Minor Variance without requiring payment to the NC Wetlands
Restoration Program. If you would like to pursue this option instead of payment
of a fee to the Wetlands Restoration Program, then please provide a monitoring
plan and conservation easement for the area to be planted. The planting plan
itself appears to be sufficient.
According to the policy guidance that the Department has developed for the
Express Review Program, applications that require on-site stormwater management,
must have a final stormwater management plan submitted with the application. From the
initial information that was discussed with Steve Mitchell and myself, we understood that
a final stormwater plan was in place. As you can tell from the above continued
questions, it is still unclear whether this is the case. If the above questions cannot be
answered quickly to assure DWQ that the stormwater plan is complete, then we will have
no option other than to require that this project be resubmitted under the regular 401
Water Quality Certification Program since submission of a final stormwater plan is not
required for that process. Therefore, if we do not receive complete answers to these
continued questions within seven (7) working days, we will have to retire this file.
Resubmission at a later date will require additional fees at that time. I can be reached at
919-733-9646 if you have any questions.

just heard from steve mitchell and he has no real objection to the variance. please get the applications

John,
I spoke with you briefly yesterday about a minor buffer variance on a site in Durham, NC Specialty
Hospitals. Unfortunately, we failed to submit the plans to you as well as to Steve Mitchell. We have
worked through Steve's concerns and have limited buffer impact to less than 1200 ft2 in zone 2.
Based upon what I have gleaned from the 401 unit's website, it appears that we need to submit 3
copies of the plan, completed Minor Buffer variance request form and $200. 1 will include the letter
from Steve in support of the plan in the package. Is there anything else you will need to complete the
review? Also, since Bob is out on paternity leave, who will be reviewing the request? Do you have an
estimate of when you believe the review will be completed? Do we need to wait on the approval from
your office to begin construction on the site?

Basically, RRO supports issuance of the minor varaiance for 1200 square feet of impact in Zone 2 and wrote a letter
saying so. see attached. While the impact could possibly be avoided entirely, it would cause problems with the
loading and unloading of semis (radius of curvature would be too much for the rigs) I bought it anyway. They have
minimized impact to the maximum and are paying WRP for the sqaure footage. Actually they already cut a check to
Ronnie but they have not been invoiced yet so it was returned. In addition, they intend to reforest the enitire buffer at
the relocated stream. The feature is shown crossing 151501 but was piped years ago. There is no doubt that it is a
subject feature and stormwater is to be treated in a regional stormwater facility .

Subject: Neuse. River Basin Riparian Buffer Rules
NBR 03-263 and 282
NC Specialty Hospital
Durham County
Dear Ms. Chessom:
I have reviewed the information submitted for the project referenced by the Raleigh
Regional Office as NBR 03-263 and 282. An evaluation of the stream features present
on the property was performed on October 30, 2003. It was determined that the stream
feature present on this tract of land has been relocated but is still subject to buffer
protection under the Neuse River Basin: Nutrient Sensitive Waters Management
Strategy; Protection and Maintenance of Existing Riparian Areas, Administrative Code
15A:20B.0233.
This letter is being written to provide confirmation to you that the Raleigh Regional Office
supports the issuance of a minor variance I accordance with the conditions listed below.
1. Impacts to Zone 2 only shall not exceed 1169 sq. ft.
2. All stormwater associated wit the development of this property shall be
conveyed to the regional stormwater facility.
3. You are required to mitigate for the impacts to the riparian buffer. The
required amount of mitigation for Zone 2 impacts is 1753.5 sq. ft per the
mitigation ration as identified in 15A NCAC 213.0242.
It is understood that you intend to plant additional trees within the protected to meet this
additional mitigation requirement. This is a suitable method to satisfy this mitigation
requirement as long as the following conditions are met:
• must include a minimum of two native species of trees
• must be planted within one year of completion of the facility
• must be replaced if any trees die within a five (5) year period.
This letter addresses only those issues involving the riparian area. For final approval of
this minor variance request or information relative to other impacts, 401/404, or wetland
issues, please contact Mr. John Dorney at 919-733-1786. Thank you for your attention

Supplemental Information for Minor Buffeftea omMEC710N
This supplement to the previously submitted buffer variance request for the NC
Specialty Hospital Site in Durham, NC is submitted in response to the letter from
John Dorney, NCDENR DWQ, dated 1/26/04.
The following items summarize and address the items in that letter.
Item 1. Provide design information on the downstream constructed
wetland.
During the initial due diligence phase, representatives from AMEC met with
representatives from the City of Durham stormwater staff to discuss the subject
site and the stormwater drainage considerations. Mr. Paul Wiebeke and Mr.
Jacob Chandler provided AMEC with record documents concerning the
Independence Park Master Plan. This drawing, dated 7/19/99, last updated
1/20/00 (copy enclosed), showed the pond labeled as "Existing Independence
Park Wet Retention Basin". At this same meeting, the City provided AMEC
copies of the as-built survey for the pond. The City explained that this pond was
designed and constructed to be a regional facility, providing detention and water
quality benefits for a this portion of the Independence Park water shed where the
BMP is located, more specifically, the portion of the Independence Park where
the subject site is located, and that sufficient volume and capacity was available
for the subject site's stormwater runoff
a) Where is it located?
The downstream BMP is a wet pond, approved by the City of Durham. It is
located approximately 420 feet east of the subject site and is shown thus on
AMEC drawing sheet C3.02. The pond is a regional stormwater quality and
quantity BMP, located within Independence Park commercial subdivision.
b) When was it constructed?
This pond was constructed in 1997 and as-built drawings were completed in
1998
c) Is the BMP sized sufficiently to treat stormwater from this site?
The wet retention basin was designed by Brunssen Engineering as part of the
initial development of the Independence Park. As part of the design submittal
to the City for the subject site, Mitchell / Westendorf Engineering, current
engineer for the Independence Park developer, was required to verify the
capacity of the existing pond and submit applicable calculations to Mr. Jacob
Chandler for review and approval for water quantity for the subject site (see
the enclosed calculations package). AMEC worked with Mitchell Westendorf
in supplying site specific information concerning the subject site development
for the revised calculations. It is our understanding that the City of Durham
has reviewed and approved these calculations. Further, we understand
through conversations with Mr. Wiebeke that the pond is not at design
capacity and that a limited amount of volume remains for additional
development within the watershed flowing to this pond. As each site is
January 29, 2004
Page 1 of 4
proposed for development, the volume capacity of the pond is re-evaluated.
At a future point, the design capacity will be met and no additional
development will be allowed to discharge to the pond without sufficient
volume and quality modifications. Mr. Wiebeke also noted that the City
currently holds a $108,000 maintenance bond on the pond.
d) Was the constructed wetland designed and constructed to meet
DWQ's stormwater BMP Manual?
In an e-mail message from Mr. Jacob Chandler to AMEC dated 7/15/03, Mr.
Chandler discussed the water quality benefits of the pond applied to the
subject site, specifically confirming a previous statement that the pond would
provide an 85% reduction in TSS, and a 25% reduction in total nitrogen.
These reduction rates were based upon the DWQ BMP manual. The subject
site property developers have chosen to "buy down" the balance of the
nitrogen removal through DENR's Wetland Restoration Program. The fee
amount for the buy down has been calculated and a check was issued.
A copy of the HEC 1 calculations prepared by Mitchell / Westendorf
submitted to the City verifying that the pond has capacity for this site is
enclosed. The City has approved the regional wet pond. Final formal
approval for the entire site plan has not yet been received, as minor site
issues unrelated to stormwater are still being addressed.
e) What measures are in place to ensure that the BMP isn't
hydraulically overloaded?
The City of Durham has a stormwater program approved by the NCDENR
Division of Water Quality. The program is designed to meet the Neuse
Riverbasin Nutrient Sensitive Waters Management Strategy. As additional
site plans within Independent Park are submitted to the City of Durham for
review, Durham staff requires the developer to provide verification that the
pond has capacity for additional stormwater. The City verifies that the
stormwater program goals are met: 85% TSS reduction, 25% nitrogen
reduction, and 1 yr 24 hr attenuation. If these reduction goals cannot be met,
the City requires additional BMPs and treatment, and no additional sites can
rely upon the pond for stormwater quality or quantity treatment.
Item 2. Provide additional information relative to the stormwater piping
system carrying stormwater from this site to the existing wet pond.
Regarding the piping of the stormwater to the wet pond, the pipe location was
determined based on negotiations with the adjacent property owner and
Independence Park developer. Development on the subject site provides allows
no room for on-site water quality / detention. Therefore, an agreement was made
with the adjacent property owners along the lowest portions of the properties
(along the stream) to provide an easement through the adjacent properties to the
wet pond. Only the outer portion of the easement (Zone 2 of the buffer) is to be
disturbed by installing the stormwater piping. The adjacent sites are currently
undeveloped.
January 29, 2004
Page 2 of 4
a) Will construction follow BMPs listed in the NRB Buffer rules?
As indicated on Drawing sheet C3.02 (previously submitted), there are
approximately 6 existing trees that will be affected by the construction of the
line. Erosion control measures will be installed and maintained along the
disturbance. Tree protection fencing will also be installed to ensure Zone 1 is
protected from construction activities. The disturbed areas of the proposed
pipe routing will be returned to natural grade and are to be stabilized in
accordance with the details as shown on Drawing sheet C4.01 and 1-1.01
(previously submitted). Erosion control blanketing will be installed to prevent
erosion and to provide an immediate cover for the disturbed areas. Tree
species will not be planted in the proposed re-vegetation of the storm sewer
pipe easement.
b) Provide an alternatives analysis for the stormwater conveyance pipe
located in Zone 2 of the buffer.
Alternative 1: Onsite stormwater treatment.
This alternative investigates the costs and benefits of constructing onsite
stormwater management facilities instead of piping the stormwater to the
existing structure downstream. As the site plan exists currently, it has
preliminary approval from the City and is awaiting final approval from the
Durham Review Board (which is contingent upon receiving the buffer
variance). The site does not have room for stormwater treatment as
designed. The site would have to be completely redesigned, and the plan
review process would begin again. Deadlines (as noted in Attachment 1
previously submitted) would be missed, and substantial costs would be
incurred based solely upon lost time and lost approvals. It is possible that the
NCSH would loose the Certificate of Need (CON) and loose the ability to
build in this location, if the deadlines in the CON are not met.
In addition to the above, the developer of Independence Park specifically
prohibits onsite treatment of stormwater as long as there is capacity in the
regional wet pond.
Benefits:
• Stormwater would be treated
Costs:
No water quality impacts related to this site development would occur.
NCSH would encounter additional design costs for the redesigned site
plan and penalties associated with the Certificate of Need.
NCSH could potentially loose the right to build upon this property,
based upon the schedules and requirements in the Certificate of
Need. As noted in Attachment 1 submitted previously, this
replacement hospital facility has been in the planning process since
1997. This surgical center is proposed to replace the existing North
Carolina Specialty Hospital, which was originally constructed in 1925
with as a state of the art facility. To date, NCSH has invested over
$2.7M and 5 years in the development of the site plan, obtaining the
January 29, 2004
Page 3 of 4
CON, pursuing permits, etc. Should this site be found unsuitable for
development as proposed, a significant amount of time and money
would have to be reinvested in the same process for another site.
• Additional costs associated with the construction of an onsite
stormwater facility would be incurred.
Findings:
• NCSH does not feel this is a suitable alternative.
Alternative 2: Install the stormwater pipe outside of the 50 ft. buffer.
This alternative investigates the costs and benefits of installing the pipe
upgradient from the 50' buffer. The developer and NCSH have already
negotiated the easement with adjoining landowners, and the easement has
already been recorded. The adjoining landowners will not allow the
easement to be placed on other portions of their property. A copy of the
negotiated easement plat is enclosed.
Benefits:
• None, as this alternative cannot be pursued.
Costs:
• None, as this alternative cannot be pursued.
Findings:
• NCSH does not feel this is a suitable alternative.
Alternative 3: Pipe stormwater for treatment in existing regional wet
pond.
As noted previously, the easement has been obtained and recorded through
the other properties. The proposed stormwater pipe will be constructed in
Zone 2 of the buffer, and tree protection fencing will be installed along Zone 1
to ensure that no vegetation is harmed by construction activities.
Furthermore, erosion and sediment control measures will be installed and
maintained during the construction process. Once construction has been
completed on the line, the area will be returned to natural grade and
stabilized with erosion control matting and seed. The natural function of the
outermost buffer zone will be restored.
Benefits:
• No additional onsite treatment is required (other than payment into
WRP).
• The site will not have to be redesigned.
• Zones 1 and 2 will be located in a permanent easement, affording
some protection from future development encroachment.
Costs:
• Typical construction costs are expected.
Findings:
• NCSH feels that this alternative is the most feasible, given the site
constraints and the capacity of the existing pond.

I submitted a HEC 1 run for the National Surgical Hospital to show attenuation of the 1 year storm event The
results I submitted to the City showed greater than a 10% kxx+ease from the 1 year storm event This analysis
was incorrect because the Post-Development Curve Number was wrong. We had used the assumed CN that
was carried over from the initial pond analysis prepared by Bnrrissen Engineering in 1998.
To summarize, we asked the design engineer to provide us with the actual impervious area for the hospital. We
applied this impervious area to the sub-basin 'E' in the HEC 1 model. This actual impervious area yielded a
lower composite CN for that sub-basin. We computed the actual composite CN for sub-basin 'E' with the new
hospital Impervious and entered that CN in the HEC-1 model. We also revised the impervious area in sub-basin
'F' to reflect undeveloped conditions. Finally, we revised sub-basin 'C' to reflect the Cardinal State Bank pre and
post developed conditions. The result was an increase in the 1-year storm of approximately 9.5%.
These are the coned results of the pre-development and posWevelopment discharge rates out of the pond.
Pre-development 1-year storm 63 cfs
Post-development Iyw storm 69 cis
Difference 6 ds = 9.5% increase
Please feel free to call or emall with any questions or comments.

The following are responses to comments for the above referenced case:
PLANNING Phvllis Melton 560-4137
1. Add case number D03-506 to site plan.
Response: Case Number has been added to Cover Sheet. This number has also
been added to the space at the bottom of the title block on all civil drawings.
2. This site is zoned GC (D) only. Remove 0I-2 (D) reference from plan.
Response: This change has been made and is referenced in the site data chart.
3. Provide a tree survey of specimen trees 18 inches or greater in diameter.
Response: This information is shown on the site survey.
4. Is the plan proposing to subdivide this parcel from the larger tract? If so, add note
to Special Conditions of Approval Box that plat must be recorded prior to
issuance of building permit.
Response: No parcels will remain separate; note will not be need to be added.
5. Specify the height of the building on sheet C2.01.
Response: This information has been added to the site data chart.
6. Correct handicapped parking sign detail to state fine of $250.
Response: This correction has been made.
7. There is a conflict with the tree preservation area and the proposed future parking.
Site plan cannot be approved with this conflict.
Response: Potential future parking has been removed from the site plan. Should
additional parking be required in the future, a revised plan will be submitted.
8. The spacing of street trees along the southwest side of Ben Franklin Blvd must be
spaced no more than 100 feet apart.
Response: Additional street trees have been added.
9. Clearly distinguish drainage easement from tree replacement area, Tree
replacement area cannot be less than 25 feet in dimension.
Response: Drainage easement has been clearly distinguished from tree
replacement area.
10. The tree coverage requirement does not meet minimum code. The required
amount is 20,829 square feet. The way you calculated your tree replacement area
is incorrect. The maximum credit per tree is 200 square feet.
Response: Per conversation on October 1, 2003 - the graduated scale is being
used. (3" cal.=225, 3.5" cal.=260, 4" cal.=275).
11. Replace Prunus Yedoensis. It is not a recommended species.
Response: All Prunus yedoensis trees have been removed from plans.

2. Show all existing state route numbers, ROW widths, pavement widths, and label
as public
Response: Right of way widths and pavement widths vary along both frontage
areas. Variable width of right of way is noted.
3. Show all existing utilities, valves, hydrants etc.
Response: These items are indicated on survey provided.
4. All proposed domestic water taps should be a minimum of 4" diameter inside the
ROW.
Response: This change has been indicated on the drawings.
5. Waterline crossings to be by bore and jack, not open cut method.
Response: This change has been indicated on the drawings. Open cut will still be
required in the area of the actual tap as the water line is located within and
existing paved area.
6. When tapping the fire line and domestic service make only one tap and tee the
domestic service before the BFP.
Response: This change has been made to the drawings.
7. Provide a drain for the dumpster.
Response: A dumpster drain has been added that connects to the sanitary sewer.
The drain is fabricated with a built in trap.
8. Send in as-built drawings for William Penn Plaza. Currently this street has not
been accepted for maintenance. We have knowledge of pavement failures and
items in need of repair. A field visit will be made to generate punch list of
corrections, after review of as-builts. No CO will be issued on this facility until
road has been accepted for maintenance.
Response: This information is being provided by the developer of the
Independence Business Park.
9. Do not allow stormwater to drain into the public ROW.
Response: Curbs cuts along the proposed development allow for on-site runoff
water to enter the storm sewer. An area of approximately 1,600 s.f. will drain into
Ben Franklin.
10. In the special conditions of approval box, add the following note: "All sizes,
materials, slopes, locations, extensions and depths for all proposed utilities
(waterlines, sanitary sewer lines and storm drainage conveyance systems) shall be
reviewed at construction drawing submittal and be subject to approval by the City
of Durham Public Works Department based upon the design criteria and standards
set forth by the Public Works Department."
Response: Note has been added to Special Conditions of Approval box.
11. Add the following italicized notes below in the special conditions box.
Response: Note has been added to Special Conditions of Approval box.
The following items are not required for site plan approval but are items that are
required before construction of water, sewer, storm drainage and streets can begin.
Developer is ultimately responsible to make certain that these items are complete and
approved.

1. There are stream buffers located on the site, clearly show the top of bank on each
side of stream, 50 foot stream buffer measured from top of band and 10 foot no
build setback measured from the stream buffer line.
Response: AMEC understands that the issue regarding the stream and required
buffers have been preliminarily resolved and that no stream exists on the property.
This finding is currently pending concurrence from the NCDEQ. The revised
drawings have been prepared based on there being no stream within the property.
2. The nitrogen calculations are not correct; the nitrogen calculations shall be
submitted as a part of the stormwater impact analysis and not on the plan. The
indicated existing impervious surface area from the calculations on the plan is
0.47 acres with 4.3 acres of managed open space for a total of 4.77 acres. This
does not appear to be correct. Based upon the post-development calculations, the
total load is 11.33 lb/acre/year. The 25% reduction for the pond downstream
yields a post-development loading of 8.4975 lb/acre/year. The nitrogen
calculations do not take into account the existing impervious surface area (i.e.,
There is no credit for existing impervious area). As such, the nitrogen buy down
amount is incorrect. The calculation should be (8.4975-3.6) lb/acre/year *$330*
4.347 acres for a total of $7,025.52.
Response: The nitrogen calculations have been revised. It is important to note
that the site has increased in size from 4.37 acres to 6.159. Likewise, the nitrogen
cales have been revised accordingly.
3. Place a note in the special conditions of approval box that states: "A site plan
cannot be approved until a receipt from the Wetlands Restoration Fund (WRF)
has been received (by the City of Durham) confirming the payment of $7,025.52
in offset fees." This letter is to serve as notice to the WRF that payment is due
Please submit a copy of this letter when making payment by mail or in person
(Mailing address: NC Wetlands Restoration Program, Attn: Carol Shaw, 1619
Mail Service Center, Raleigh NC 27699-1619, phone number [phone], fax
5321).
Response: Note has been added. The revised amount calculated based on the
increased acreage is $3604.99.
4. The Rational Method C values are incorrect; refer to the Reference Guide for
Development for Rational C values based upon HSG soil type. Please send email
to ichandlerOci.durham.nc us and copy of the Reference Guide will be emailed to
you.

Response: The revised calculations are attached.
5. It does not appear that you will be able to extend the existing 72' CMP per
comment #1 above.
Response: See response to Item #1 above.
6. Thel-year storm analysis is incorrect. The analysis point shall be at the point
where runoff from the site enters a Neuse River Basin Stream, which is located on
the property, refer to Durham County Soil Survey streams. The 1-year detention
must be provided on-site, the downstream pond does not attenuate the 1-year
storm per my email to Tommy Martin. In this case, it does not matter if the pond
provides 1-year detention or not because the analysis point for the 1-year storm is
incorrect.
Response: AMEC has been informed that a revision submittal has been made to
the City by Mitchell Westendorf that allows for the design as shown without the
on-site detention. It is our understanding that this will not be required due to the
capacity of the downstream pond, previously approved. Our drawings have been
revised without on-site detention based on this understanding.
7. Place this note in the special conditions of approval box: An executed storm
water facility operation and maintenance permit agreement (prepared by
Stormwater Services, City of Durham), payment of storm water facility permit fee
($2,000 per detention/ water quality device) and perpetual surety for the continued
operation and maintenance of the facility is required prior to construction plan
approval.
Response: This note has been added.
8. Place this note in the special conditions of approval box: An as -built certification
for the stormwater BMP(s), provided by the design engineer, is required prior to
issuance of a certificate of occupancy.
Response: This note has been added.
9. Place this note in the special conditions of approval box: A completed City of
Durham Design Summary is required (for each detention /water quality device)
no later than at the first construction drawing submittal.
Response: This note has been added.

Response. Recyclables are collected at given points within the hospital and
routinely deposited in a dumpster in the loading dock area where they are picked
up on a regular basis by a recycling company with whom the hospital has a
contract.
POLICE Mark Lipton 5604582
Planning Department note: While the Police Department is aware of our
ordinance requirements, they and we are concerned also about safety, including
visibility and lighting. These comments are recommendations only, and should not
in any way be construed as a replacement for the landscaping requirements
outlined in the Zoning Ordinance. It is possible to address both the Zoning
Ordinance requirements and the Police Department's concerns through the use of
larger plant materials spaced further apart, to give some degree of visibility and
satisfy the requirements of our ordinance. It is also possible to add more lighting
and place them away from the trees, so as not to interfere with the ability of the
lights to do their job. Editing by Planning is shown in bold italics.

9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: During site preparation, the subdivision developer placed fill
material from other lots on this lot. Sparse vegetation currently exists at the site. Grading for
this site plan has not yet begun. Land use surrounding the site is mostly urban. This site is
situated within a commercial subdivision.
10. Describe the overall project in detail, including the type of equipment to be used: This
construction site is one tract (4.6 ac) within an overall commercial subdivision. It is going to
be developed as a hospital including parking lots, driveways and landscaped areas. The
exact nature and extent of the construction equipment will be determined by the contractor,
but anticipated equipment includes: bulldozers, dump trucks, front-end loaders, and cement
trucks. Most heavy equipment will be restricted to outside the buffer zone. However, some
construction equipment will be utilized within Zone 2 of the buffer in order to install the
access drive. No disturbance will be allowed in Zone l of the buffer. Trees will be hand-
planted in Zone 1.
11. Explain the purpose of the proposed work: The purpose of this project is to create a new
surgical center to replace an older hospital facility built in 1925 in another location within
Durham.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules.
In October 2003, Steve Mitchell with the DWQ Raleigh Regional Office evaluated the site for
the presence of a stream. He determined the stream feature within the tract was a stream and was
subiect to the Neuse Buffer Rules. The DWQ Raleigh Regional Office project # is NBR03-263
and 282. Plans were developed to address Mr. Mitchell's concerns at the site, and a package was
submitted to him for approval of a minor buffer variance. On December 16, 2003, Mr. Mitchell
issued a letter supporting the plans so the site developer could approach the Durham review
board for approval. Mr. Mitchell's letter is included.
Page 7 of 14
An overview of the site conditions follows: The 4.6 acre site has been graded and filled with
approx. 20' of fill by subdivision developer in an effort to make the site more marketable.
Currently, it is cleared and grass covered. The fill material used is a variable composition of
clayey and sandy soil mixed with gravel, asphalt, concrete, brick and organics. Please see
the supplemental geotechnical report for more details. The stormwater flow off the site is
currently 11.77 cfs based on a 10-year return event. After the planned construction is completed,
the stormwater flow off the site will be 22.53 cfs based on a 10-year return event. Please see the
supplemental stormwater plan for more details.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
At this time, future permit requests are not anticipated.
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, permanent
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must be shown on a
delineation map, whether or not impacts are proposed to these systems. Wetland and stream
evaluation and delineation forms should be included as appropriate. Photographs may be
included at the applicant's discretion. If this proposed impact is strictly for wetland or stream
mitigation, list and describe the impact in Section VIII below. If additional space is needed for
listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: We do not anticipate stream impacts.
Only impacts to Zone 2 of the buffer are anticipated. 1169 ft2 of new imperviousness is
planned in Zone 2 of the buffer. However, tree plantings are for both Zones 1 and
2 to enhance the value of the buffer. Payment into the NC Wetlands Restoration Prop-ram
offset the buffer impact as well.

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
justification for the final layout, including the 1169 ft` of impact to Zone 2. It has been included
with this submittal as "Attachment 1".
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
Page 10 of 14
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmp,ide.html.
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
While stream and wetland impacts are not anticipated for this site, riparian buffer impacts
are. See Attachment 1, Alternative 4 and map L1.01 for more information about the buffer
impacts.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wr32/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet):
Amount of buffer mitigation requested (square feet): 1169 ft2
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):
IX. Environmental Documentation (required by DWQ)
Does the project involve an expenditure of public (federal/state) funds or the use of public
(federal/state) land?
Yes ? No
If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?

coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No ?
If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEPA or SEPA final approval letter.
Yes ? No ?
X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 213 .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?
Yes ® No ? If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.
Zone* Impact
(square feet Multiplier Required
Mitigation
1 0 3 0
2 1169 1.5
Total 1 169 1.5 $1683.36
* Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
2
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or.0260.
As outlined in Attachment 1 and supported by Steve Mitchell with DWO's RRO. we propose to
pay $1683.36 into the Wetlands Restoration Program and to enhance the buffer by_planting trees
in Zones 1 and 2. A total of 50 trees (of two different species will be planted in the buffer.
Stormwater from the site will be piped to an existing, pre-approved (by the City of Durham)
stormwater wetland down gradient from the site. The stormwater wetland provides the required
Page 12 of 14
30% nitrogen reduction. See map # L3.01 for outfalls and map # L1.01 and L1.02 for site
landscape plans and buffer delineations.
XI. Stormwater (required by DWQ)
Describe impervious acreage (both existing and proposed) versus total acreage on the site.
Discuss stormwater controls proposed in order to protect surface waters and wetlands
downstream from the property.
Currently, there are no impervious surfaces on this tract (100% pervious). The proposed
impervious area is 2.5 ac of 4.6 ac (54% pervious). Stormwater from this site will not be
discharged into the buffer, so flow diffusion is not required. Instead, stormwater will be routed
through a culvert to a stormwater wetland downstream that was previously approved by the City
of Durham for the reduction of nitrogen for the entire commercial development. While the
stormwater culvert will be constructed in Zone 2 of the buffer, no impervious area will be
created in this area, and no impacts to Zone 1 are anticipated. See maps C3.01 and C3.02 and
stormwater site plan narrative.
Total acres=4.6 Total build-out impervious acres=2.48 Total area disturbed=3.8 ac. See map
C3.01.
XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
The sewage is discharged into an 8" sewer line and ties in to city sewer line. See map C.501
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H.0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application?
Yes ? No
XIV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
NOSH has been developing these plans since 1997. City approval schedules, Certificate of Need
schedules (required for hospitals), and environmental permitting schedules all have to be met.
To meet several schedules, NCSH hopes have the DWQ Buffer Variance approval by January 15

Addendum to the Pre-Construction Notification and "Buffer Rules" Application Required for
Projects Submitted Under the
"Express Review Program"
North Carolina Division of Water Quality Version 3.0
January 7, 2004
Email Address: [e-mail]
Purpose: To provide a detailed explanation of the information required by the Division of Water Quality
in order to expedite the review of applications for 401 General Water Quality Certifications, Isolated
Wetland and Stream Permits, and Buffer Rule and Minor Variance Approvals.
Please do not leave any questions unanswered or use terms such as "N/A" without an explanation.
Fees:
Total stream impacts of less than 150 feet and/or total wetland impacts of less than or equal to 1 acre -
$1,000.00.
Total stream impacts of greater than or equal to 150 feet and/or total wetland impacts of more than 1 acre
and projects that include any kind of Buffer Rules Approval -$2,000.00. For stream origin determinations
as required by the Buffer Protection Rules the fee is $200.00 for one or two streams on the same
property, $500.00 for three to six streams on the same property, or $1,000.00 for more than 6 streams on
the same property.
Please read the entire document before attempting to determine the proper fee. Fees are additive for a
particular project.
Things to keep in mind when filling out the application:
A specific answer must be provided for each question. For instance, if a numerical answer is requested
then a numerical answer must be provided along with the supporting information necessary for DWQ staff
to verify that the number is accurate. Likewise, if explanations are presented to justify certain responses,
the explanations must be completely supported by documentation. DWQ staff cannot assume that
unsupported or undocumented information is accurate. "N/A" is not an acceptable answer for any
question since the DWQ Staff reviewing the application must have an opportunity to determine whether or
not any requested information is pertinent.
All forms, guidance, worksheets, applications, etc. used must be the current versions as posted on our
web site at http:h2o.enr.state.nc.us/ncwetlands. There will soon be a web site specifically for the express
review program. Please note that it will be the applicant's or applicant's consultant's responsibility to
verify that the current versions are used. The versions posted on our web site will be considered to be
the current versions.
You are a very important part of the success of this program, if you have suggestions or clarifications
please send your comments to the Wetlands/401 Unit of the DWQ (via email at
401 [e-mail]).
Filling Out the Pre-Construction Notification Application:

SECTION III - PROJECT INFORMATION
The following is the most critical of all the information that you must provide. The quality and detail of the
information will often determine the expeditiousness of the review. The following is a checklist of the
types of pertinent information required at a minimum:
3
Maps and Plans:
The most recent version of the 1:24,000 USGS Topographic Map- Please cleanly
delineate the site boundaries, etc. on the map. If the delineation obscures any of the
features, it is recommended that a clean copy be provided. Please indicate the
quadrangle name. You can go to the USGS web site (http://mac.usgs.gov/maplists/) to
verify the most recent version.
The most recent version of the NRCS Soil Survey Map - (required for projects within
the Neuse River Basin, Tar-Pamlico River Basin and Randleman Lake Watershed and
recommended for all projects) - Please cleanly delineate the site boundaries, etc. on the
map. If the delineation obscures any of the features, it is recommended that a clean copy
be provided. Please indicate the page or map number from which the copy of the map
was made. Copies of the current soil survey and/or soil survey map sheets can be
obtained from the local NRCS County Office (http://www.nc.nres.usda.gov/).
,F(' Vicinity map - Please clearly mark the location and approximate boundaries of the
property and project on the map. Please indicate north and scale. Please include
applicable road names or State Road numbers.
The Site Plan - The most critical map to be provided is the site plan. You must provide
full sized plans. The following is the minimum list of plans that are typically needed. ^ ZY (]
Pre-construction/Pre-existing conditions - This sheet must be scaled and (, 1
include all jurisdictional and non-jurisdictional wetland, stream, water features, Cl v?
State regulated buffers, topographic contours with elevations, approximate extent
and nature of forest, field, landscaped, or other cover. Any existing structures and
impervious area must also be shown. Existing utility lines and easements must
also be shown. Existing roads, culverts, and other pertinent features must be
shown. North arrow and the scale must be shown. Please note that the impact
boundaries on the maps should correspond to the flagged impact boundaries in the
field.
y/ Proposed conditions - These sheets must be scaled and show all existing
jurisdictional and non-jurisdictional wetland, stream, water features, and State e, 3.
regulated buffers must be underlain on the site plan(s). The plans must show all
built-out structures and impervious cover. The plans must include the final grading
contours with elevations. The plans must indicate all utilities and easements. It is
likely that several versions of the final built-out site plans will be necessary. The
following is a list of layers:
)( Drainage Plans - Final drainage plans must be included. The plans should include C 3.a?
the locations and pertinent elevations and sizes of the collection system and ?Z
drainage ways. All inlets and outlets must also be shown with pertinent elevations. '
Scaled stormwater BMPs must also be indicated as required by DWQ rules and
policies. In certain cases, final stormwater management plans must also be
provided, but that will be addressed later in this document.
Plats - The plans must show the location and layout of all sub-divided parcels with CI V
lot identifications. Platted parcels must be developable without further impacts to
jurisdictional and non-jurisdictional wetlands, streams, water features, and State
regulated buffers.
Proposed Impacts - All impacts to jurisdictional and non-jurisdictional wetland, ?I.d)
stream, water features, and State regulated buffers must be shown and labeled on C
the site plans. All excavation, fill, flooding, stabilization, and other impacts that will
e, 3.c)2
be conducted in or near jurisdictional and non-jurisdictional wetland, stream, water
features, and State regulated buffers must be indicated.

Wetland Impacts (on the site plan): Il1l?CW.4dC iiW aft Q,a?+u?Ct'c? .
C Precise grading and final elevation contours must be provided. Existing vegetation and
any clearing must be specified.
F All subsurface utility lines must indicate the location of anti-seep collars. Construction
detail for anti-seep collars must be provided.
F_ Roadway or other crossings of riparian wetlands may require floodway culverts to
maintain existing hydrological conditions.
C When surface drainage features or groundwater recharge areas that feed or would
reasonably feed wetlands that are not to be filled are made impervious, it may be
necessary to direct some stormwater runoff to those areas in order to maintain hydrology.
You must identify these areas and address them. Supporting explanations and discharge
information must be provided to show that the wetland would not be eroded or receive
too much or too little hydrology. In many cases this could help satisfy part of a
stormwater management plan.

Any widening of the stream must be s#?bwn with elevations. QeG ?P
The extent of and plan details for all dissipation or grade control devices should be shown
with pertinent elevations.
F For shorter culvert sections, such as for road crossings, a longitudinal cross section that
shows the stream bed invert at the inlet and outlet, the existing stream bank elevations
and the invert of the inlet and outlet of the pipe(s) must be provided.
For shorter culvert sections, such as for road crossings, a vertical cross section must be
provided that shows the stream cross section at the inlet and outlet overlain with the
culvert and fill cross section.
For bottomless culverts or other spans, a vertical cross section should be provided that
shows the minimum distance from each span to each stream bank, the stream cross
section, the height of the span above the stream and the minimum distance from the
edge of each footer to each stream bank.
For bottomless culverts or other spans, a plan view must be provided that shows the
location of the spans and the stream banks.
For longer culverts or culverts that will pass beneath substantial impervious cover, it will
be necessary to provide adequate plan detail to show that discharge velocity/energy will
be adequately dissipated.
L_ Aquatic life passage through culverts is typically achieved by placing the invert of the
culvert below the existing bed of the stream per the USACE or North Carolina Wildlife
Resource Commission guidelines. Other methods such as baffles may also be used.
Please be aware that such placement may require the use of grade/velocity control
measures up or down stream of culverts on steeper streams to prevent head-cuts or
stream bed erosion. The culvert placement relative to the stream bed can be indicated
on the longitudinal profile. Grade and velocity control measures must be indicated on the
plan view and typical designs should be provided.
F Multiple culverts, wide culverts or sectioned box culverts typically require the use of sills,
off-setting or other means to match the cross section of the existing stream (in order to
maintain stream stability and provide aquatic life passage). A vertical cross section of the
culverts should be shown overlain with the up and downstream stream cross section
including the stream flood-prone area.
F Impacts associated with dam construction must indicate and enumerate all fill associated
with the dam foot print, spillway and any bank stream bank stabilization. The length of
stream impounded must also be indicated and enumerated.
Stream Relocations: 6trtatm r., to _1 PL ac X4u
I Stream relocations must be conducted as specified in General Certification numbers
3402 and 3404 (available on the Wetlands Unit web site). Stream relocation plans must
include:
C Morphological measurements (see Appendix B of the Internal Technical Guide for Stream
Work in North Carolina available on the Wetlands Unit web site) - not all of the
measurements are applicable in every instance.
F Typical stream cross sections - Typically, a riffle cross section and a pool cross section
that includes the entire flood prone area. The bankfull and flood prove area elevations
should be indicated. Similarly, a riffle cross section of the reference stream(s) should be
provided.
Plan view - Provide scaled plans that show the location of the proposed (preferably with
stationing) and the existing stream. In most instances, the bankfull contours and flood
prone area contours, in stream structures, bank revetments/stabilization, channel plugs,
planting plan, vegetation conditions, stormwater outlets, grade controls, bridges, culverts,
sewer lines, roads, fencing, and easement lines should also be provided.
f Longitudinal Stream Profile - A scaled profile that indicates the thalweg , bankfull, and
top of bank elevations should be provided for the design and reference streams. In many
cases, it will also be necessary to show the existing land elevations for the design
stream.
C Planting Plan - A planting and/or vegetation management plan should also be provided
that makes use of appropriate native vegetation. The plan should indicate the extent,
density, and species of plants to be provided.
I- In-stream structure, bank revetment/stabilization, and stormwater outlet typicals -
Detailed, typical plans should be provided for all in stream structures, bank revetments or
stabilization, and stormwater outlets. The typicals should include materials and
specifications as well as relative lengths, positions, and angles.
C Sediment transport analysis - A sediment transport analysis should be provided based
on the current, relevant, accepted practices. The sediment transport analysis should be
relevant to the stream bed load type and should predict bed load transport equilibrium.
C Permanent conservation easement or similar means of protection must also be provided.

copy of the final approved, site plan.
SECTION V - FUTURE PROJECT PLANS
For projects utilizing the express review process, all impacts both present and
potential future must be indicated. For instance, the location or configuration of
platted lots sometimes suggests that future impacts will be necessary to build,
access, or otherwise develop such lots. Failure to account for such potential impacts
could delay or disqualify a project from the rapid review process. If you believe that
the lot can be developed without impacts, but you anticipate that your assertion may
be questioned, it is recommended that you provide a potential building foot print
and/or grading plan to show that future impacts could be avoided.
SECTION VI -PROPOSED IMPACTS TO WATER OF THE US ?M
f- C (S 0ft t,,. ' ,, 1 - 6*,
?L 1. It is recommended that the individual impacts be described if there are special things
to note about the impacts. Typically the most important thing is to have detailed
accurate site plans as described above. Please make sure they are clearly labeled.
? Please include all proposed temporary impacts.
? Also, a current, signed delineation map from the USACE should be provided (if
available) and a map locating the stream origins signed by the appropriate DWQ
Staff must be provided if applicable.
E 2. Each impact to a wetland must be clearly labeled and identified on the site plan. The
type of impact must be clearly stated. If the impact is temporary, a specific plan must
be described or shown as to how the wetland will be restored. Keep in mind that the
USACE delineates some features as wetlands that DWQ calls streams. Please do
not list any impacts in this table that DWQ would identify as a stream. If there is any
doubt, it is recommended that the impacts be listed as streams.
1 3. Each impact to a wetland must be clearly labeled and identified on the site plan. The
type of impact must be clearly stated. If the impact is temporary, a specific plan must
be described or shown as to how the wetland will be restored. Keep in mind that the
USACE delineates some features as wetlands that DWQ calls streams. Please list
any impacts in this table that DWQ would identify as a stream. If there is any doubt, it
is recommended that the impacts be listed as streams. Please follow current DWQ
policy with respect to whether a stream is perennial or not. It is recommended that
you assume that a stream is perennial (unless you are positive that it is not) so if
mitigation is required then the appropriate amount of mitigation would be anticipated
or requested from the WRP or private bank. If the WRP or private bank has pre-
approved too short of an amount of stream or if inadequate mitigation is proposed,
then that situation will result in delays.
C 4. Sometimes it is difficult to determine whether a feature is a modified natural channel
or a ditch, especially in the eastern part of the State. Soils, drainage features,
topography, and similar factors, all are important for making that determination.
Other items to address not specifically requested in the application include
downstream sediment starvation, thermal pollution, low flow releases from dams, and
aquatic life passage. Other important considerations are buffer reestablishment or
mitigation around ponds on buffered streams. The site plan should include the
precise elevation contour of the normal pool as well as the dam foot-print. Mitigation
9
is required for wetland flooding of an acre or greater and for stream fill (if over the
150 foot threshold) under the dam foot-print and any outlet stabilization.
SECTION VI - AVOIDANCE AND MINIMIZATION
Avoidance and minimization are critical aspects of an application particularly if you desire the application
to be processed expeditiously. The following is a check-list of avoidance and minimization questions that
DWQ Staff often look for in applications.
Are there any stream crossings at angles less than 75° or greater than 105°? l6
5me Are there any stream crossings that cross two streams above or at the confluence of those hLD
streams?
5? Are there any stream, wetland, water, and/or buffer impacts other than perpendicular road\(eS, rte-
crossing near the edges of the property? U.01 "J

X Can cul de sacs be used in place of a crossing? tom, ? AW4&'
Can lots be reshaped or have shared driveways to avoid impacts? flazoe, 5w, MCUL;artlN 44 i
If based solely on the practicable physical possibility, the answer is "yes" to any of the above questions
then you must have to provide substantial and convincing justification as to why the impacts are
necessary. If the impacts are required by a local government or other agency the claim must be
supported with appropriate written documentation from the local government or other agency. Most
projects typically involve the need to justify avoidance and minimization. If this information is not readily
available, then the express review process may not be the appropriate venue to use because the project
may be put on hold at the end of the process. Providing alternative plans (such as plans that avoid the
impact, minimize the impact and the preferred plan, similar those used in environmental assessments)
and explanations as to why the preferred plan is needed and why the alternative plans won't work are
many times helpful in the no practical alternatives review.
SECTION VIII - MITIGATION
Mitigation for the Express Review Program, final mitigation plans must be presented up front. The final
plans (except for plans that propose payment into the Wetlands Restoration Fund, Riparian Buffer
Restoration Fund, private mitigation banks, or similar banking instruments) must contain detailed plans,
specifications, calculations and other supporting data that show that the appropriate mitigation will be
achieved at the ratios required. The design plans must be developed to at least the "90%" level.
Monitoring plans must be final and specific. Any means of permanent protection, such as a permanent
conservation easement must be provided. If you elect to use the WRP or a private mitigation bank, it is
10
recommended that you request the maximum possible mitigation amount that DWQ may require so that
you will not have to get further approval from them on short notice. The WRP and private banks are not
part of the expedited review process and cannot be expected to meet any such deadlines. There will be
no conditional expedited approvals that require final plans at a later date. It is not recommended that
innovative mitigation techniques or greater than 10% preservation be requested as part of an expedited
process.
SECTION IX
If your project requires the preparation of an environmental document under NEPA or SEPA and an
approval letter has not been issued by the State Clearinghouse, then you cannot apply under the
expedited review process. I t is your responsibility to find out if such documentation is required.
SECTION X
There are many aspects of the Buffer Rules that must be addressed in every application, if applicable.
The first and most important thing to keep in mind is that allowable activities that require written Approval
from DWQ triggers a review of the entire project for compliance with the Buffer Rules.
Diffuse Flow & Stormwater Management:
X The most common issues that arise involve the requirement for diffuse flow of stormwater
through riparian buffers. Basically one of three things must be indicated in regards to all
"new" stormwater that is collected and subsequently discharged. First, provisions for
diffuse flow through the protected buffer must be made. This usually involves the use of
level spreading devices designed to the latest DWQ guidance on level spreader design,
which is available on our web site. Please keep in mind that it does not matter how far a
discharge point is from a buffer. The stormwater must be flowing in a diffuse manner at
whatever point it eventually reaches the buffer. If the stormwater will not be flowing in a
diffuse manner through the protected buffer at the point it reaches the buffer, then one of
the following options may be allowed:
You may provide a nitrogen removing measure such as a forested filter strip,
3,Q2 QYIa
grassed swale, stormwater wetland, etc. The measure employed should b e e
designed according to the NC DENR Stormwater Best Management Practices ?J'?11
Manual or other DWQ Guidance available at httI3 `?'>sC. ?KN
//h2o.ehnr.state.nc.us/ncwetlands/mitresto.html. After the nitrogen is treated, the PI4A ,
stormwater can be directly conveyed through the buffer with written DWQ approval.
? You may discharge the stormwater to an existing man-made conveyance that
currently conveys stormwater through the protected buffer (assuming the
conveyance was not constructed in violation of the Rules) as long as that
conveyance does not need to be altered to convey the flow. Please remember that
there are no other choices. The following checklist is intended to help insure that
your application will not be deemed incomplete as a result of improper stormwater
design.
Stormwater Management (for Buffer Rules compliance only - Also, see Section XI):
y? All stormwater out-falls must be clearly shown and labele on the site plan for projects in
Buffered watersheds. List each out-fall as labeled: Ou - I
D Option 1: Level spreading devices designed to the latest DWQ Guidance, and

eiok?
F1 All stormwater out-fall must meet one of the options above. (Note: if you cannot check this
box your application will likely not be accepted into the express review process.)
Site Plans:
All applications on properties with DWQ protected buffers must clearly depict the buffers ea.()?
and any impacts to the buffers on the site plans. The impact maps should clearly depict LJ.0
both zones of the protected buffers and the proposed impact areas (provided in square
feet).
Surface Water & Buffer Delineations:
Any surface waters subject to DWQ protected buffers must be field located and accurately 0,ol
depicted on the site plans and impact maps. The width, dimensions and pattern of the
surface water must be delineated. The surface water location must not be taken simply
from a USGS map, soil survey or local municipality's map. The buffers must be measured
from the surface water as required within the applicable buffer protection rule (e.g., all
buffers along streams subject to the Neuse Buffer Rule must be measured from the "top-of-
bank" of the stream and not the centerline of the stream). All streams must be surveyed or
located by GPS and shown precisely on the site plans.
Impact Table:

corresponding impact site. ` vKe i* may,,.} Q(m. 6 aiicu n b&4

Projects that require the Minor and "General" Variances may be eligible for the use of the? Nwz
Express Review Program. However, Major Variances are not eligible. If your project
requires a Minor or "General" Variance approval, then be sure to attach a completed Minor
or "General" Variance application.
Mitigation:
As opposed to applications that are submitted under our regular process, final mitigationWywa
plans must be presented up front (see requirements for Section VIII above). The mitigation04'''''40'h)

Attention: Mr. Dennis Solheim
SUBJECT: REPORT OF GEOTECHNICAL SERVICES
PROPOSED SPECIALTY SURGICAL FACILITY
DURHAM, NORTH CAROLINA
MACTEC PROJECT NO.: 6468-03-0284
Dear Mr. Solheim:
MACTEC Engineering and Consulting, Inc. (MACTEC), formerly LAW Engineering and
Environmental Services, Inc. (LAW) has completed the additional subsurface exploration at the
above referenced site. The work was authorized by you, on July 18, 2003, with our Proposal
Number PROP-03-RAIL-439. The results of this exploration, along with a boring location plan,
test boring records, test pit records, and our geotechnical recommendations are included herein.
The assessment of site environmental conditions or determining the presence of contaminants in
the soil, rock, surface water, or groundwater of the site was beyond the scope of this exploration.
PURPOSE OF EXPLORATION
MACTEC performed a geotechnical exploration for this site in September 2001. At that time,
construction debris was identified across the back half of the site and was encountered in some of
the borings. The purpose of this exploration was to further evaluate the extent of the debris,
condition of fill materials, estimate a seismic Site Class and review our original recommendations
in light of the additional data obtained from this exploration.
PROJECT INFORMATION
Site information was provided by Ms. Sara Snodgrass of The CFP Group (CFP) and National
Surgical Hospitals (NSH). We understand that NSH desires to construct a combined 1 and 2-
story surgical facility at the corner of Ben Franklin Boulevard and William Penn Plaza, as shown
on Drawing 1 in the Appendix. We understand the second story will be placed over the eastern
side of the building. A proposed site plan was provided by CFP and additional borings and test
pits were selected. Final grades were not provided but we assume they will be close to present
grades. Column loads for the structure are estimated at 250 kips in the two-story areas and 100
kips in the one-story areas.
FIELD EXPLORATION
Seven boring locations were selected within the proposed building plan. These borings were
advanced to auger refusal. To supplement the normal sampling and testing procedures, eight test
pits were excavated using a backhoe to further evaluate the quality of fill materials as well as to
explore for construction debris.

The approximate boring and test pit locations are shown on Drawing 2 in the Appendix. The
boring and test pit locations were located in the field by MACTEC pers nnel by taping distances
and estimating right angles from existing site features. These locations should be considered
accurate only to the degree implied by the methods used.
A truck-mounted CME 75 power-drilling rig using hollow stem auger rilling procedures
performed the borings. Samples were taken by driving a 1-3/8 inch ID plit-spoon sampler in
general accordance with ASTM D 1586 specifications at 1.5-foot to 5. foot intervals.
Representative portions of all samples were sealed in glass jars and retu ed to our laboratory where
they were visually classified in accordance with the Unified Soil Classification System. MACTEC
will store the test boring samples, available for inspection, for a period of ninety days after which
time they will be discarded unless requested otherwise.
The evaluation and recommendations presented in this report were devel ped from an interpretation
of the general subsurface conditions at the site based on information ob fined from the soil borings.
The stratification lines indicated on the boring logs represent the approximate boundaries between
soil types; in-situ, the transitions may be gradual. Variations in soil con itions between borings can
also occur.
LABORATORY TEST RESULTS
Two bulk soil samples of the surficial soils were collected at the site fort laboratory testing to aid in
pavement thickness evaluations. One bag sample was tested and the results are summarized below.

Additionally, the Maximum Dry Density as determined by the Standard Proctor Test was 107.9 pcf
at 17.5 % moisture content. The California Bearing Ratio (CBR) test as also performed on this
sample and determined to be 2.0%.
SITE AND SUBSURFACE
The subject site is located at the southeast corner of Ben F levard and William Penn
Plaza in Durham, North Carolina. The site is approximate) 1.5 Broes in size and is presently
cleared. Original site contours provided during the first exploration indicate that this site was a low
lying area with grades sloping to the east. At the time of our present exploration, the site was open
and grass covered. Comparing present grades to original topography, it appears as much as 20 feet
of fill has been placed on the site. Additional fill soil mixed with ravel was piled along the
drainage easement to heights of about 6 feet +/-. Additional debris consisting of asphalt, rocks,
concrete curbing, and organics (i.e. tree) has been pushed over the eastern edge of the site, where
fill depths are estimated to exceed 20 feet.
The proposed site is located in the Triassic basin, one of several trough shaped basins that occur in
the Piedmont Physiographic Province. The basins were created about 220 million years ago when
faulting activity caused long narrow areas to drop several thousand feet relative to the surrounding
areas. Soil and rock materials were eroded from the adjacent areas and deposited in inland fresh
water lakes within the troughs to form sedimentary rocks. The Triassic rocks consist of sandy and
A'MACTEC

clayey sandstone, siltstone, mudstone, and shale. Isolated calcareous zones exist in the fine-grained
rocks, and occasional coal beds are interbedded with gray to black shales and siltstones. The colors
of Triassic rocks include yellow, maroon, red, reddish-gray, brown, and purple; however, brownish-
purple predominates. Conglomerate and fanglomerate are found along both the eastern and western
margins of the basins.
Fill and possible fill was encountered at all, test boring locations. The depths of the fill material
ranged from 6 to 20 plus feet below present grades. The fill soils are clayey, silty and sandy soil
mixed with gravel, asphalt, concrete, brick, rock fragments and some organics. The fill is quite
variable across the site with respect to composition, moisture conditions and insitu density.
Standard Penetration Test (SPT) results varied from 4 to greater than 100 blows per foot where
concrete and/or rock fragments were encountered.
Borings B-9A, B-13, B-13A, B-1313, and B-13C encountered refusal at varying depths. The
refusal depths were shallower than adjacent borings which may indicate construction debris was
encountered. Borings B-9, B-10 B-11, and B-13D encountered Partially Weathered Rock (PWR)
at depths of 24 to 34 feet. Borings B-14 and B-15 encountered PWR at depths of 13 and 18 feet,
respectively.
The residual soils underlying the fill materials generally consist of silty sandy clay and sandy clayey
silt. Partially Weathered Rock (PWR) was encountered in Borings B-9, B-10 B-11, and B-13D at
depths of 24 to 34 feet. Borings B-14 and B-15 encountered PWR at depths of 13 and 18 feet,
respectively. The PWR typically sampled as hard, fine sandy silt with some rock fragments.
The results of 8 test pits excavated across the site are summarized in the table below.

in the proximity of PWR were typically wetter than those above which suggests some perched
water may exist at the soil/PWR interface. Cave-in depths often indicate approximate water
elevations; however, the moisture content of the samples in the proximity of the cave-in
elevations was generally dry, thus the cave-in depths may indicate variations in fill types or
consistency as opposed to moisture level. Fluctuations in the location of the groundwater table
may occur depending on variations in precipitation, evaporation, and surface water runoff.
Pictures of the site were taken during the test pit excavation on July 8, 2003 and are attached in
the Appendix. The pictures show some of the test pits as well as debris along the eastern fill
slope.
RECOMMENDATIONS
The test borings, test pits and observations made during this exploration reinforce our earlier
indications that uncontrolled fill and debris has been placed on the site. The fill consists of
construction demolition debris and some organics. The existing fill is not suitable for support for
building foundations. Voids may exist within the debris that could collapse under loading.
Organic materials will degrade over time resulting in additional voids. As the voids collapse or
new voids are created, settlement of structures supported on the existing fill may occur. The
magnitude and/or rate of settlement cannot be predicted.
The safest approach to dealing with the variable fill is to undercut to firm native soils or PWR and
backfill the undercut areas with properly compacted structural fill. This approach would result in
excavations of 14 to 16 feet within the building area and up to 20 or more feet along the eastern
side of the site. The disadvantage of extensive undercutting includes excessive costs for
excavation, backfill, and disposal of material.
Excavations of these depths may be required to stabilize the slope along the eastern side of the
site to support the proposed roadway around the back of the building. At the time of writing this
report, no information has been provided concerning the plans for retaining the eastern slopes,
and thus no recommendations or analyses have been performed.
Recognizing the disadvantages of extensive undercutting, we recommend three possible
alternatives for the building area.
Option 1) Undercut six feet, dynamically compact the remaining soils, and backfill with
structural fill and geogrids,
Option 2) Dynamically compact the surface and construct a structural slab or `mat'
foundation system, and
Option 3) Construct 36 to 42 inch diameter drilled shafts through the fill and bear in
PWR and support the building structure and slab.
Option I Undercut with Dynamic Compaction
Site Preparation
Within the footprint of the building and to a distance of at least 10 feet outside the building limits,
all existing fill should be removed to at least 5 feet below the foundation bearing elevation.
Assuming footings are at least 18 inches below grade, excavation depths will be about 6.5 feet.

Page 5 of 10 MACTEC Project No. 6468-03-0284
Prior to placing compacted fill in the excavation, we recommend that large debris, if encountered,
be removed from the surface and that the exposed subgrade be densified using a site improvement
technique known as impact densification (also known as dynamic compaction). This technique is
performed by specialty contractors and involves dropping a large 15 to 35 ton weight from a
crane in a grid pattern across the areas to be improved. The weight of the impact drives craters
into the subgrade, densifying the debris and reducing the void spaces. The craters are then
backfilled with structural fill or crushed stone. This option is generally very effective in reducing
void space and limiting settlement. It is also well suited to an open site such as this. It is
normally cost effective for thicknesses of debris fill of about 8 to 10 feet or greater. For lesser fill
thicknesses, it is likely to more expensive than undercutting. We are available to provide more
specific recommendations regarding impact densification as the project develops.
From our experience with Dynamic Compaction, vibrations have the tendency to dampen out
relatively quickly. It is likely that the adjacent buildings will experience minor vibrations during
compaction, however these vibrations are not likely to cause any damage. We would want to
review vibration concerns with the MRI center, located across the road from the site, prior to
finalizing our recommendations.
Fill in the building excavation should consist of granular material placed in 8 to 10 inch thick lifts
with each lift compacted to a minimum of 95 percent of the standard Proctor maximum dry
density, ASTM D 698. The fill should be reinforced with geogrid (Tensar BX1200 or similar) on
10 to 12 inch vertical centers. The geogrid reinforcement should extend vertically to the
proposed bottom of footing elevation.
Foundations
Assuming existing fill in the building area is removed, the area densified, and structural fill
placed as recommended above, structural loads can be supported on shallow depth spread or
continuous footings. Foundations should be designed for a maximum net allowable soil bearing
pressure of 2,000 pounds per square foot. All exterior footings should be located at least 18 inches
below final exterior grades to provide adequate frost protection. Interior footings may be embedded
only a nominal depth if in an area that will not be subject to frost heave. Minimum footing widths
of 16 inches for wall footings and 24 inches for column footings are recommended. The use of strip
footings (rather than isolated footings) will help distribute the loads and limit differential settlement.
If a brick veneer will be used, we recommend using frequent vertical joints in the veneer to
accommodate some settlement.
We recommend that the geotechnical engineer or technician observe the footing excavations
immediately prior to placing concrete. Any soft or loose soils should be undercut to suitable
materials and backfilled with approved soil fill materials, clean stone, or lean concrete. Soil backfill
should be placed as described above. Footing excavations bearing in properly compacted fill need
only be checked and cleaned of loose soil prior to concrete placement. All foundation bearing areas
should be level or suitable benched and free of loose soil, ponded water and debris.
Exposure to the environment may weaken the soils at the footing bearing level if the foundation
excavations remain open for long periods of time. If the bearing soils are softened by surface water
intrusion or exposure, the softened soils must be removed from the foundation excavation bottom
immediately prior to placement of concrete.

Slabs
Proposed Durham Surgical Facility
Durham, North Carolina
MACTEC Project No. 6468-03-0284
If the above recommendations are carried out, the ground floor slab may be designed as a slab-on-
grade supported on properly compacted fill. Prior to construction of the floor slab, the subgrade
soils should be free of standing water or mud. A layer of washed stone or coarse sand, as well as a
suitable moisture barrier, should be provided beneath the slab to prevent capillary rise and a damp
slab.
The grade slab should be jointed along footing-supported walls so the slab and foundation can move
differentially without damage. The joints may contain dowels or keys to allow rotational movement
between slab sections without cracking or sharp displacements.
Option 2 Dynamic Compaction at the surface and construction of a Structural Slab "Mat"
Foundation
Within the footprint of the building and to a distance of at least 10 feet outside the building limits,
the existing surface could be dynamically compacted as described above and the craters
backfilled as recommended. Once this process has been completed, a structural slab or mat
foundation could be constructed a minimum of 18 inches below the final grade elevation.
Any depressions from the dynamic compactions should be backfilled with structural fill which
should utilize a low plasticity soil (liquid limit less than 50, plasticity index less than 25) free of
organic material or debris. It may be possible to reuse some of the existing fill for compacted fill
outside the building area. Organic materials in the existing fill should be removed. Concrete or
rock fragments should be broken down to 4 to 6 inch pieces so that they can be incorporated into a
single fill lift. All fill should be placed in 8 to 10 inch loose lifts and should be compacted to at
least 95 percent of the standard Proctor maximum dry density (ASTM D 698).
Option 3 Construction of Drilled Shaft Foundation and Structural Slab
Another option that could be used to support the structure would involve the construction of 36 to
42 inch diameter drilled shafts. These shafts should be extended through the debris and fill
materials and socketed one diameter into weathered rock and/or rock. An endbearing capacity of
40 ksf allowable can be used for structural design calculations for shafts that are constructed as
recommended below.
A temporary protective steel casing should be installed in the drilled hole. This will prevent side
wall collapse and allow access to remove debris or some obstructions that may be encountered in
the excavation during the shaft construction. Debris removal may include but is not limited to
cutting wood or jack-hammering concrete and rock. A minimum drilled pier diameter of 36 to 42
inches is recommended to provide reasonable entry space for cleaning, debris removal, bottom
preparation, and inspection.
The protective steel casing may be extracted as the concrete is placed. However, the protective
steel casing should not be moved until the concrete is above the groundwater level. A head of
concrete, 1.5 times the shaft diameter, should be maintained above the bottom of the casing during
withdrawal and the contractor should prevent concrete from "hanging-up" inside the shell which
can cause soil and water intrusion below the shell.

Page 7 of 10 MACTEC Project No. 6468-03-0284
Concrete slumps ranging from 4 to 7 inches are recommended for the drilled pier construction.
Concrete with slumps in this range will usually fill irregularities along the sides and bottom of the
hole, displace water as it is placed, and permit placement of reinforcing cages into the fluid
concrete.
We recommend that the concrete placement into the drilled hole be directed through a centering
chute at the surface to prevent contact with the sides of the hole. This procedure will reduce side
flow and segregation.
The geotechnical engineer should be retained to observe the drilled pier construction. He should
document the shaft diameter, depth, bell size, cleanliness, plumbness, and type of bearing material.
Significant deviations from the specified or anticipated conditions should be reported to the owner's
representative and to the foundation designer. The drilled pier excavation should be observed after
the bottom of the hole is leveled, cleared of any mud or extraneous material, and dewatered.
We recommend that the drilled pier construction include at least one probe hole in the bottom of
each drilled pier excavation. The probe holes should be about 1.5 inches in diameter and are
usually drilled to a depth of at least 1.5 times the pier bottom diameter or to 10 feet, whichever is
less. Each hole should be checked by the geotechnical engineer with a steel feeler rod to assess the
rock continuity. If this check indicates discontinuous rock or compressible seams, the drilled hole
should be excavated deeper. Additional probe holes may be required by the geotechnical engineer
to check piers supported on marginal material.
Once the shafts have been constructed, a grade beam and structural slab should be used to support
structure. This approach will result in minimal settlements within the structure.
The major drawback to this approach is the possible cost involved due to construction difficulties.
The final foundation cost will be driven by what debris is encountered at each shaft location and
the subsequent labor to extend the shaft to PWR or rock. Due to these conditions, it may difficult
to estimate the cost of this foundation type.
Structural Fill
Any structural fill or backfill placed at the site should utilize a low plasticity soil (liquid limit less
than 50, plasticity index less than 25) free of organic material or debris. It may be possible to reuse
some of the existing fill for compacted fill outside the building area. Organic materials in the
existing fill should be removed. Concrete or rock fragments should be broken down to 4 to 6 inch
pieces so that they can be incorporated into a single fill lift. All fill should be placed in 8 to 10 inch
loose lifts and should be compacted to at least 95 percent of the standard Proctor maximum dry
density (ASTM D 698). The upper 12 inches below proposed pavements should be compacted to at
least 98 percent of the standard Proctor density. The moisture content of the fill should be
maintained within 3 percent of optimum.
We recommend that all cut and fill slopes be no steeper than 3H:1 V. Fill slopes should be
constructed by overfilling and then trimming back to the fmal configuration. All slopes should be
seeded as soon as possible after grading to minimize erosion.

Construction Considerations
When soils similar to those at the site become saturated, they lose strength and become difficult to
compact. Therefore, the contractor should promptly remove any surface water or groundwater from
the construction area. This has been done effectively on similar construction projects by means of
gravity drainage and sump pumping.
We recommend that construction begin in the drier months of the year to minimize difficulties
relating to the upper cohesive soils which will become wet, soft, and difficult to compact when rains
occur. The surface soils should be protected from excessive infiltration and surface water by
grading the site to promote the rapid clearing of rainwater and surface runoff from the building
areas both during and after construction.
The near surface soils at this site classify as Type B in accordance with current OSHA Trench
Protection Guidelines. Trench excavations more than 4 feet deep should be supported with
temporary shoring and bracing or cut back on slopes of 1 H:1 V
Additional Services Recommended
1. Site Preparation and Proofrolling: The geotechnical engineer or technician should observe
the site after it has been stripped and excavated. The engineer should determine the extent
of undercutting or in-place densification necessary to prepare the subgrade for fill
placement or for slab support.
2. Fill Placement and Compaction: The geotechnical engineer or technician should observe
any required filling operations and take sufficient in-place density tests, approve borrow
materials used and determine if their existing moisture contents are suitable.

3. Footing Excavation Examination: The geotechnical engineer or technician should examine
the footing excavations for the building foundations. He should check that the design
bearing pressures recommended are available and that soils beneath the bearing surface of
the footing excavations are suitable. Based on the examinations, the engineer would either
approve the bearing surface or recommend that unsuitable soils be undercut to expose
satisfactory bearing materials.
4. Pavement System Examination: Pavement subgrade soils and base materials should be
examined by the geotechnical engineer or technician prior to placement of the asphaltic
concrete to determine that proper compaction has been achieved and that project
specifications are being followed. California Bearing Ratio (CBR) tests should be
performed on representative samples of the subgrade soils in order to develop a suitable and
economical pavement section.
CLOSURE
These analyses and recommendations are, of necessity, based on the concepts made available to us
at the time of writing of this report and on site conditions, surface and subsurface, that existed at the
time of the exploratory borings. Further assumption has been made that the limited exploratory
borings, in relation to both the areal extent of the site and depth, are representative of conditions
across the site.

North Carolina Specialty Hospital Durham Site
Alternatives and Minor Buffer Variance Request
North Carolina Specialty Hospital (NCSH) has been pursuing development
plans for a site located on the corner of Ben Franklin Boulevard and William
Penn Plaza in Durham, NC. The site has been graded and filled upon by
the original developer prior to NCSH development plans. During site
?-? grading and filling, the drainageway located along the southeastern
C73 property line was altered. The original site plan assumed that this
drainageway was not a stream. However, after preparing the plan, the
DENR DWQ determined that the drainageway is, in fact, a stream and is
subject to the Neuse Riverbasin Riparian Buffer rules. This document
0 outlines the site development alternatives, considering site planning and
development costs and impacts to stream buffers. It is assumed that the
drainageway is a stream.
While the primary issue addressed by this document is stream buffer
?-+ impact and the need for a variance from the Neuse Riverbasin Riparian
CCC3 Buffer rules, the timelines and permitting restrictions can affect other site
issues, such as the City or Durham's review process and the Certificate of
Need (CON).
Alternative 1: Do not build.
Un
This alternative investigates the costs and benefits of not building the
surgical center at this site.
?? Benefits:
C) • The stream buffer would not be impacted by this development.
However, it is improbable that the site would remain undeveloped.
CIZ3
U • Water quality would not be impacted by this development.
Costs:
• This replacement hospital facility has been in the planning process
since 1997. This surgical center is proposed to replace the existing
Q North Carolina Specialty Hospital, which was originally constructed in
1925 wi* as a state of the art facility. To date, NCSH has invested
over $2.7M and 5 years in the development of the site plan, obtaining
the CON, pursuing permits, etc. Should this site be found unsuitable for
development as proposed, a significant amount of time and money
would have to be reinvested in the same process for another site.
Findings:
• NCSH does not anticipate this alternative as being an option.

Alternative 2: Leave the site plan as originally submitted to DENR
DWQ.
This alternative outlines the timeframes, costs and benefits of leaving the
site plan as originally submitted to DENR DWQ and submitting a request
for a major variance from the Neuse Riverbasin buffer rules. In this
alternative, the access roadway around the building (required by fire codes)
will impact the riparian buffer in both Zones 1 and 2.
Benefits:
• The site plan does not have to be redesigned.
• The City of Durham Planning Department can review the plan as a
revision, and the review time is shortened. Also, the plan can be
reviewed by the City Council in January.
CIZI Costs:
• Approximately 3.515 square feet of linear buffer impact would be
expected. This impact would consist of 3290 square feet of impervious
con surfaces in Zone 2 of the buffer and 225 square feet of disturbance in
® Zone 1.
• A major variance of the Neuse Riverbasin Riparian Buffer rules would
be required. The review process would dictate that the Environmental
r? Management Commission (EMC) would have to review the variance
request after the regional and central offices of DWQ reviewed the plan.
Given the timeframes required to get on the EMC's agenda as well as
CIZ3
. r..? the upcoming holidays, this site plan would be placed on the February
C„) agenda if a major variance request were submitted immediately. It is
Q) likely that deadlines established in the CON would be missed, causing
major monetary penalties.
Findings:
CC3 • DWQ Regional Office field staff, Steve Mitchell, does not support this
alternative, and therefore it is unlikely that the EMC would approve the
site plan as originally submitted.
• NCSH does not anticipate this alternative as being an option.
Clzs
U Alternative 3: Change the southwestern access to cross the stream.
This alternative outlines a reorientation of the southwestern access road.
Instead of accessing the site from Ben Franklin Road on the northern side
of the stream (as originally proposed), the access road would be moved to
the southern side of the stream, still accessing the site from Ben Franklin
(sketch attached). The access road would then cross the stream and
impact the buffer perpendicularly. Under the Neuse Riverbasin Buffer
rules, perpendicular road crossings are permittable as long as the buffer
impact is "minimized".
Page 2 of 4
approved by the City of Durham to reduce the nitrogen loading by 30%.
The regional wetland BMP also addresses water quantity control.
Benefits:
• The redesigned site plan would have minimal buffer encroachment.
• Additional tree plantings will be provided in Zone 2.
• It is anticipated that the City of Durham would not consider the
redesigned site plan as a new plan, and that the review time for the
redesign would be comparatively short.
• Deadlines within the CON would be met, avoiding large penalties.
Costs:
• NCSH would encounter additional design costs for the site plan and
for the stream restoration plan.
Findings:
,C4----07 NCSH would like to pursue this option.

Benefits:
• The buffer encroachment would be permittable under the buffer rules.
Therefore, DWQ approval would be automatic.
Costs:
• Significant redesign costs would be likely.
• Some parking would be lost. However, limited parking spaces could be
added to the southern-most section of the site.
• The building and parking areas would still have to be shifted to allow
the road access around the building for fire code requirements without
any linear impact to the buffer.
• It is likely that the City of Durham would consider the site redesign
significant enough to require a new site plan review, increasing review
----- 4 time and review fees.
a3 • While the buffer impact would be permittable by DWQ, the overall
..' impact on the stream would be high. The southern property line along
the stream is approximately 315 feet long. The stream discharges onto
the site from a 72" cmp about 200' into the property. Moving the
access road to the southwest would likely create a situation where the
stream is piped, daylighted for a short distance, then piped under the
access road for 60-80', and then daylighted again. Impacting the
stream in this manner, while permittable by DWQ, destroys the value of
the stream.
CIZ3 Findings:
V NSH does not anticipate this alternative as being an option.

Alternative 4: Redesign the site to have limited impact to Zone 2 and
apply for a minor buffer variance.
CC3 This alternative includes shifting the site plan to the north towards William
Penn (see enclosed plans). Impact to the buffer is minimized. A minor
buffer variance would be required for 1169 square feet of impervious area
? ) in Zone 2 of the buffer. There will be no impact in Zone 1.
? NCSH will pay into the Wetlands Restoration Program, as described in
15A NCAC 0213.0242 Neuse River Basin Nutrient Sensitive Waters
Management Strategy: Mitigation Program for Protection and Maintenance
of Existing Riparian Buffers. The payment will be:
1169 ft2 x 1.5 x $.96/ft2 = $1683.36
NCSH will also provide tree plantings in Zone 2 of the buffer, in addition to
?--? the offset payment (see enclosed plans).
Also, all stormwater from the NCSH site will be routed to a downstream
regional stormwater quality wetland, built previously by the developer and
