Approval of 401 Water Quality Certification and Authorization Certificate per the Neuse
River Buffer Protection Rules (15A NCAC 2B .0233) with Additional Conditions
Dear Mr. Falcone:
You have our approval, in accordance with the attached conditions and those listed below, to
place fill within or otherwise impact 115 linear feet of perennial stream, 3,580 square feet (ftz) of
Zone 1 Neuse River basin protected riparian buffers and 589 square feet (ft2) of Zone 2 Neuse
River basin protected riparian buffers to construct the proposed residential subdivision, as
described within your revised application dated October 13, 2006 and received by the N.C.
Division of Water Quality (DWQ) on March 6, 2007. After reviewing your application, we have
decided that the impacts are covered by General Water Quality Certification Number(s) 3631
(GC3631). The Certification(s) allows you to use Nationwide Permit(s) 29 (NW29) when issued
by the US Army Corps of Engineers (USAGE). This letter shall also act as your approved
Authorization Certificate for impacts to the protected riparian buffers per 15A NCAC 2B .0233.
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 LAMA 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 1501inear 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:

Buffer -Zone 2 589 (square ft.) PCN page 8 of 9
2. Erosion & Sediment Control Practices
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.
3. 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.
4. Diffuse Flow
All constructed stormwater conveyance outlets shall be directed and maintained as diffuse
flow at non-erosive velocities through the protected stream buffers such that it will not re-
concentrate before discharging into a stream as identified within 15A NCAC 2B .0233 (5). If
this is not possible, it may be necessary to provide stormwater facilities that are considered to
remove nitrogen. This may require additional approval from this Office.

5. Protective Fencing
The outside buffer, wetland or water boundary and along the construction corridor within
these boundaries approved under this authorization shall be clearly marked with orange
warning fencing (or similar high visibility material) for the areas that have been approved to
infringe within the buffer, wetland or water prior to any land disturbing activities to ensure
compliance with 15A NCAC 2B 33 and GC 3402.
6. Construction Stormwater Permit NCGO10000
Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of
Land Resources (DLR) or a DLR delegated local erosion and sedimentation control program,
an NPDES General stormwater permit (NCGO10000) administered by DWQ is automatically
issued to the project. This General Permit allows stormwater to be discharged during land
disturbing construction activities as stipulated by conditions in the permit. If your project is
covered by this permit [applicable to construction projects that disturb one (1) or more acres],
full compliance with permit conditions including the sedimentation control plan, self-
monitoring, record keeping and reporting requirements are required. A copy of this permit
and monitoring report forms may be found at
http: //h2o. enr. state. nc. us/su/Forms Documents. htm.
7. Culvert Installation
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 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 mariner 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
Cary Park, LLC

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.
8. Deed Notifications
Deed notifications or similar mechanisms shall be placed on all retained jurisdictional
wetlands, waters and protective buffers in order to assure compliance for future wetland,
water and buffer impact. These mechanisms shall be put in place prior to impacting any
wetlands, waters and/or buffers approved for impact under this Certification Approval and
Authorization Certificate. A sample deed notification can be downloaded from the
401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. The text of the sample
deed notification may be modified as appropriate to suit to this project.
9. Written Stormwater Management Plan (No Further Approval Needed)
The final, written stormwater management plans (including a signed and notarized Operation
and Maintenance Agreement), must be implemented and the stormwater management
facilities shall be constructed and operational before any permanent building is occupied at
the subject site. 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.
10. No Sediment & Erosion Control Measures w/n Wetlands or Waters
Sediment and erosion control measures shall not be placed in wetlands or waters to the
maximum extent practicable. If placement of sediment and erosion control devices in
wetlands and waters is unavoidable, they shall be removed and the natural grade restored
within six months of the date that the Division of Land Resources has released the project.
11. Certificate of Completion
Upon completion of all work approved within the 401 Water Quality Certification or
applicable Buffer Rules, 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.
Violations of any condition herein set forth may result in revocation of this Certification and may
result in criminal and/or civil penalties. The authorization to proceed with your proposed
