Re: Glen Creek Subdivision 401/404, Buffer Compliance Application
Raleigh, NC
SEPI Project # EN14.051.00
On behalf of the owner Glen Creek, LLC, please find attached a complete application and
supplemental information requesting written concurrence from the U.S. Army Corps of Engineers
( USACE) and the N.C. Division of Water Resources (DWR) that the activities proposed below may
proceed under Nationwide Permit 29 and General Water Quality Certification 3890.
This project was originally delineated by another firm in 2007. NBRRO 07 -275 corresponds with
the buffer determination made by Ms. Lauren Witherspoon (previously with NCDWQ) on
November 29, 2007. Additionally a 401 and buffer approval (DWQ Project # 08 -1015) was
previously issued on October 13, 2008. The approval allowed for 140 linear feet (LF) of stream
channel impact and 7,304 ftz of riparian buffer impact. The project was never initiated or
constructed.
It is assumed that a corresponding 404 permit was applied for and obtained however a copy of
this permit has not been located. Likewise it is assumed that a jurisdictional determination was
obtained however a copy of this has not been located either.
Sean Clark and Kim Hamlin of SEPI Engineering redelineated the streams and wetlands on the
property in December of 2014 to ensure that the necessary data was available and conditions
had not changed. The attached impact maps depict the updated delineation. In areas within the
100 -year floodplain where no impacts were planned a general "wetland matrix" line was marked
in the field to be used as a visual barrier. Some upland areas exist within the wetland matrix
area, however no wetlands exist outside the wetland matrix area that aren't otherwise identified.
In addition to the request for 401 and 404 approvals, a preliminary jurisdictional determination is
also being requested from the USACE
Due to the location of the project, streams on the project not only have the 50 -foot Neuse River
Riparian Buffers but also have an additional 50 -foot buffer beyond that providing a 100 -foot
buffer on each side of the streams. Streets on the project will not use curb and gutter but will
rather use grassed shoulders and swales /ditches to convey stormwater.
In an effort to reduce the overall impacts on the project the road crossing location was slightly
altered to cross at a less sinuous location. Stream impacts have been reduced from the
previously permitted 140 LF to the currently proposed 130 LF Due to the reduction in stream
impacts and the fact that impacts are less than 150 LF we do not believe that stream mitigation

should be required Proposed impacts to riparian buffers are also within the "allowable" limits
(less than 1/3 acre) of the rules, therefore riparian buffer mitigation is not proposed. Currently
proposed impacts are provided within the table below.

Impact Justification and Mitigation
1.
Avoidance and Minimization
la
Specifically describe measures taken to avoid or minimize the proposed impacts in designing project
An updated delineation was requested for the project in order to insure that proposed impacts would be avoided
and minimimized to the maximum extent practicable Impacts were avoided at the project entrance and were limited to a
single road crossing The Road crossing was minimized from what was previously permitted by realigning the crossing
location to provide a more perpendicular crossing Additional 50 -foot buffers are added to the 50 -foot Neuse River Buffers
which provide a total of 100 feet of buffer on each side of the streams
1 b
Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques
Orange fabric fencing (or the like) will be utilized to insure that jurisdictional areas are not impacted Lot grading
will be minimized to maintain the existing terrain and vegetation as much as possible

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
(hqR: / /www nedot org d/ oh/ol2erationsBMP manual/download/BMP Manual.odfl
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 foraaquatic life movement as well as to prevent
head cutting of the streams. If any of the existing pipes are or become perched, the appropriate

Buffaloe Preserve, LLC
Page 3 of 5

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 mkt bin Aced- below-

and 20 ercent of the culvert diameter for c v s ha n a dia a inches, to allow
low flow passage of water an 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.

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 Qualityupon 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 2B .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
October 8, 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. Stormwatbr 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
shall allow for the ability to maintain the structures, perform corrective actions as described

'1,
Buffaloe Preserve, LLC

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 &Ivi 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.
7. 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;
8. 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 xeturn the attached
certificate of completion to the 401 Oversight/Express Review Permitting 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 impacts or to conduct
impacts to waters as depicted, in your application and as authorized by this Certification, shall expire upon
expiration of the 404 or CAMA Permit.
If you do not accept any of the conditions of this Certification (associated with the approved wetland or
stream impacts), 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, 6714 Mail Service Center,
Raleigh, N.C. 27699 -6714. This certification, and its conditions are final and binding unless you ask for a
hearing.
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 letter completes the review of the Division of Water Quality under Section 401 of the Clean Water
Act and the Neuse riparian buffer protection rule as described within 15A NCAC 2B .0233. If you have
