EXPLAINATION OF CHECKLIST ITEMS NOT SPECIFICALLY PROVIDED
• A submerged and vegetated perimeter shelf at less than 6:1 is provided. The pond shoreline
follows the natural slope approaching the stream. It is flatter than 6:1 for most of the perimeter,
however a portion of the perimeter steepens to approx. 3:1.
• A minimum 30-foot vegetative filter is provided at the outlet. The outlet discharges into a
natural stream and is therefore not vegetated.

Dear Mr. Howard:
The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined
that additional information is necessary to complete the technicalreview process. The required additional
information is as follows:
Permanent Water Quality Pool, Temporary Water Quality Pool
The Temporary water quality pool (storage) appears to be inadequate for pond B. Also, please send a
1:30 scale site plan for the newly designed pond B. Please note that the plans for pond B dated
January 12, 2000 were approved, as required by the Water Quality Certification, for DWQ project
number 991256. However, it appears that the Division neglected to send the approval letter. The
Division apologizes for this over-site.
2. Inlet/Outlet Structure Location
The outlet structure for pond A should be located in the eastern "lobe" of the pond to maximize flow
path.
3. Vegetative Shelf
A vegetative shelf of 6:1 side slopes around the perimeter of pond C should be provided.
Additionally, a retaining wall cannot be exposed below the permanent pool level of pond C. Please
specify this on the engineering plans.
4. Operation and Maintenance Agreement
An operation and maintenance agreement is required. Typical requirements for an operation and
maintenance plan include the following:
Vegetation management/mowing schedule
• Semi-annual inspections
• Debris check after every storm event
• Benchmark for sediment removal (specific elevations listed)

EXPLAINATION OF CHECKLIST ITEMS NOT SPECIFICALLY PROVIDED
• The basin length to width ratio is greater than 3:1. The pond is formed by placing a dam in a
natural stream channel. The resulting length to width ratio is approx. 2.6:1.
• A submerged and vegetated perimeter shelf at less than 6:1 is provided. The pond shoreline
follows the natural slope approaching the stream. It is flatter than 6:1 for most of the perimeter,
however a portion of the perimeter steepens to approx. 3:1.
• A minimum 30-foot vegetative filter is provided at the outlet. The discharge from the opnd is
into a natural stream and is therefore not vegetated.

Winston-Salem, North Carolina 27103-1834
Dear Mr. Sohmer:
You have our approval, in accordance with the attached conditions and those listed below, to place fill material in 146 linear
feet of streams the purpose of constructing stormwater ponds at Jefferson Village - New Garden Road as, described in your
application dated 12 November, 1999. After reviewing your application, we have decided that this fill is covered by General
Water Quality Certification Number 3108. This certification allows you to use Nationwide Permit Number 26 when the Corps of
Engineers issues it. In addition, you should get any other federal, state or local permits before you go ahead with your project
including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Water shed
regulations. This approval will expire when the accompanying 404 or CAMA permit expires unless otherwise specified in the
General Certification.
This approval is only valid for the purpose and design that you described in your application except as modified below. 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 Certification and approval letter and is thereby responsible for complying with all
conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory niNgation may be required
as described in 15A NCAC 2H .0506 (h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the
attached certification and any additional conditions listed below.
I . Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or
areas within 50 feet of all streams and ponds to notify the state in order to assure compliance for future wetland and/or water
impact. These mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 404 Permit
(whichever is later).
2. An additional condition is that a final, written stormwater management plan, shall be approved by this Office before the
impacts specified in this Certification occur. The stormwater management plan must include plans and specifications for
stormwater management facilities designed to remove 85% TSS according to the most recent version of the NC DENR
Stormwater Best Management Practices Manual. Also, before any permanent building is occupied at the subject site, the
facilities, as approved by this Office, shall be constructed and operational, and the stormwater management plan, as approved
by this Office, shall be implemented.
3. The slope of the dam shall be stabilized with vegetation as soon as possible after construction. Use of riprap for stabilization
shall be minimized.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act
within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to Chapter
150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-
7447. This certification and its conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have
any questions, please telephone John Dorney at 919-733-9646.

Subject: Pre-Construction Notification Application
Jefferson Village - New Garden Road
Greensboro, Guilford County, North Carolina
ECS Project G-2750
Dear Mr. Domey:
a.??.
f« .
Please find seven copies of the Pre-Construction Notification Application for the above referenced site. The site is
approximately 80 acres in area and is located on New Garden Road in Greensboro (Figure 1). The site was
originally a portion of the Jefferson Pilot property and is known as Lots 6 and 7. The site is to be commercially
developed by Highwoods Properties.
A 401 Water Quality Certification was previously issued for the Jefferson Pilot property. A condition of the
certification is that a stormwater plan designed to meet 85% TSS removal be approved by the DWQ prior to
beginning construction activities. To satisfy this requirement, Highwoods Properties has chosen to construct three
water quality ponds on the site. The total surface area of the ponds is 143,230 square feet. Two of the ponds are
located in non jurisdictional areas. The third pond will be constructed in a tributary of Horsepen Creek that crosses
Lot 7. It is necessary to place the pond in this area due to space and topography constraints. The locations of the
proposed water quality ponds are illustrated on the attached exhibit.
The construction of the water quality pond on Lot 7 will result in an impact to 146 linear feet of stream channel due
to the construction of the dam. Approximately 275 linear feet of stream channel will be flooded by the pond. We
are requesting a 401 Water Quality Certification for the impacts to the stream channel due to the construction of the
pond.
A tributary of Horsepen Creek crosses the former Jefferson Pilot property. We understand that a conservation
easement along this tributary has been granted to the Wetland Restoration Program for stream mitigation.
According to Mr. Harold Bynum, Attorney for Jefferson Pilot, Highwoods Properties may be allowed to use excess
stream mitigation credits to satisfy any mitigation requirements imposed by the U.S. Army Corps of Engineers or
the NCDENR.
Please feel free to contact me at [phone] if you have any questions concerning this request or if additional
information is required. Thank you in advance for your timely consideration of this matter.
