Buffer Protection Rules (15A NCAC 2B.0233) with Additional Conditions
Dear Mr. Alavi:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 149 linear feet of perennial stream, and 6,830 square feet of Zone 1 Neuse
River basin protected riparian buffers and 6,095 square feet of Zone 2 Neuse River basin protected
riparian buffers, as described in your application dated June 16, 2008, and received by the Division of
Water Quality (DWQ) on June 16, 2008,with additional information received from you on June 17, 2008,
August 28, 2008, September 5, 2008, and October 9, 2008, to construct the proposed residential
development at the site. After reviewing your application, we have decided that the impacts are covered
by General Water Quality Certification Number(s) 3705 (GC3705). The Certification(s) allows you to
use Nationwide Permit(s) NW29 when issued by the US Army Corps of Engineers (USACE). 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 regulations. Also, this approval to proceed with your proposed impacts or to conduct
impacts to waters as depicted in your application shall expire upon expiration of the 404 or CAMA
Permit.
This approval is 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 Certification and approval letter and is thereby responsible for
complying with all conditions. If total fills for this project (now or in the future) exceed one acre of
wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A
NCAC 2H.0506 (h). This approval requires you to follow the conditions listed in the attached
certification and any additional conditions listed below.
The Additional Conditions of the Certification are:
1. Impacts Approved
The following impacts are hereby approved as long as all of the other specific and general
conditions of this Certification (or Isolated Wetland Permit) are met. No other impacts are
approved including incidental impacts:

2. No Waste, Spoil, Solids, or Fill of Any Kind
No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond
the footprint of the impacts depicted in the Pre-Construction Notification. All construction
activities, including the design, installation, operation, and maintenance of sediment and erosion
control Best Management Practices, shall be performed so that no violations of state water quality
standards, statutes, or rules occur.
3. Erosion and sediment control practices must be in full compliance with all specifications governing
the proper design, installation and operation and maintenance of such Best Management Practices in
order to protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed,
operated, and maintained in accordance with the most recent version of the North Carolina
Sediment and Erosion Control Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control
measures must be such that they equal, or exceed, the requirements specified in the most
recent version of the North Carolina Sediment and Erosion Control Manual. The devices
shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects,
including contractor-owned or leased borrow pits associated with the project.
c. Sufficient materials required for stabilization and/or repair of erosion control measures and
stormwater routing and treatment shall be on site at all times.
4. Sediment and Erosion Control Measures
Sediment and erosion control measures shall not be placed in wetlands or waters without prior
approval from the Division. If placement of sediment and erosion control devices in wetlands and
waters is unavoidable, design and placement of temporary erosion control measures shall not be
conducted in a manner that may result in dis-equilibrium of wetlands or stream beds or banks,
adjacent to or upstream and down stream of the above structures. All sediment and erosion control
devices shall be removed and the natural grade restored within two (2) months of the date that the
Division of Land Resources or locally delegated program has released the project;
5. Culvert Installation
All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP
measures from the most current version of NCDOT Construction and Maintenance Activities manual
(http://www.ncdot.orgJdoh/operations/BMP manual/download/BMP Manual pdf)
such as sandbags, rock berms, cofferdams and other diversion structures shall be used to prevent
excavation in flowing water.
Culverts required for this project shall be installed in such a manner that the original stream
profiles are not altered. Existing stream dimensions (including the cross section dimensions,
pattern, and longitudinal profile) must be maintained above and below locations of each culvert.
Culverts shall be designed and installed to allow for aquatic life movement as well as to prevent
head cutting of the streams. If any of the existing pipes are or become perched, the appropriate
Highland Builders, Inc.
Page 3 of 5
October 13, 2008
stream grade shall be re-established or, if the pipes installed in a perched manner, the pipes shall
be removed and re-installed correctly.
Culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the
stream up or down stream of the culvert(s). Existing stream dimensions (including the cross section
dimensions, pattern and longitudinal profile) shall be maintained above and below locations of each
culvert.
Placement of culverts and other structures in waters, streams, and wetlands must be placed below
the elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches,
and 20 percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow
low flow passage of water and aquatic life. Design and placement of culverts and other structures
including temporary erosion control measures shall not be conducted in a manner that may result
in dis-equilibrium of wetlands or streambeds or banks, adjacent to or upstream and down stream
of the above structures. The applicant is required to provide evidence that the equilibrium shall be
maintained if requested in writing by DWQ.
The establishment of native, woody vegetation and other soft stream bank stabilization techniques
must be used where practicable instead of rip rap or other bank hardening methods. If rip-rap is
necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of
Water Quality.
Installation of culverts in wetlands must ensure continuity of water movement and be designed to
adequately accommodate high water or flood conditions.
Upon completion of the project, the Applicant shall complete and return the enclosed "Certificate
of Completion" form to notify NCDWQ when all work included in the §401 Certification has
been completed. The responsible party shall complete the attached form and return it to the
401 /Wetlands Unit of the NC Division of Water Quality upon completion of the project. Please
send photographs upstream and downstream of each culvert site to document correct installation
along with the Certificate of Completion form.
6. Diffuse Flow (DWQ Reviewed Plans)
All stormwater shall be directed as diffuse flow at non-erosive velocities through the protected
stream buffers and will not re-concentrate before discharging into the stream as identified within
15A NCAC 213.0233 (5)
In an effort to comply with the diffuse flow provision of the Buffer Rule (15A NCAC 02B
.0233(5)), you have provided the DWQ with level spreader designs received by the DWQ on
September 5, 2008, and October 9, 2008. The DWQ believes that if implemented, as per these
plans, diffuse flow will be achieved. However, if diffuse flow as per 15A NCAC 02B.0233(5) is
not achieved, then the DWQ shall be notified and corrective actions to restore diffuse flow shall
be taken if necessary to impede the formation of erosion gullies. At no time shall stormwater
from the proposed development be piped directly through the buffer without prior DWQ written
authorization.
The structural stormwater practices as approved by this Office as well as drainage patterns must
be maintained in perpetuity. No changes to the structural stormwater practices shall be made
without written authorization from the Division of Water Quality. Stormwater easements shall be
recorded for a distance of at least 10 feet on each side of all stormwater conveyances on all lots
containing these structures including future access for maintenance. The stormwater easements
Highland Builders, Inc.
Page 4 of 5
October 13, 2008
shall allow for the ability to maintain the structures, perform corrective actions as described
above and shall provide protection of the structures from potential alternations by future property
owners.
An Operation & Maintenance (O&M) agreement signed by the current landowner must be
approved by the DWQ. This O&M agreement must transfer with the sale of the land or transfer
of responsibility for the stormwater facilities and the DWQ must be notified of every transfer.
Mitigation:
7. Compensatory Mitigation Using the Ecosystem Enhancement Program (EEP)
