B. Project Information and Prior Project History
5. Project History
5a. Have permits or certifications been requested or obtained for
® Yes ❑ No ❑ Unknown
this project (including all prior phases) in the past?
5b. If yes, explain in detail according to "help file" instructions.
On May 7, 2008 and August 5, 2008, the USACE and NC DWQ, respectively, authorized impacts to 0.0977 acres of
wetland impact (0.0947 acres permanent impact and 0.003 acres temporary impact), 110 linear feet of permanent
important/perennial stream channel and 11,785 square feet of riparian buffer impact (7,180 square feet of Zone 1 and
4,605 square feet of Zone 2). On July 22, 2010, the NC DWQ Raleigh Regional Office (RRO) issued a letter relating to
their June 2010 site inspection. This was followed by an August 30th Notice of Violation letter which cited unpermitted
riparian buffer impacts related to Sediment Pond 1. Follow up site visits by NC DWQ RRO staff in September and
October resulted in an October 12`" Notice of Continuing Violation, Notice of Intent to Enforce letter related to the original
Riparian Buffer violations in addition to subsequent sediment violations. A site meeting with Mr. Danny Smith and Ms.
Lauren Witherspoon in October 2010 was held to discuss the violations on -site and appropriate remediation requirements
which lead to the submittal of an "After- the -fact" Riparian Buffer Impact request. That request was approved on January
27, 2011. In 2012, the subject property was sold to DR Horton. At this time, DR Horton is confining the site development
to upland areas only on the eastern portion of the site. This Buffer Authorization Request is for a single riparian area
impact associated with a stormwater device outlet bypass swale.
6. Future Project Plans
6a. Is this a phased project?
® Yes ❑ No
6b. If yes, explain.
This project has always been shown as a phased development. Phase I is currently under construction. The initial permit
application submitted in 2008 clearly shows the Phase lines on the overall impact map. All proposed impacts were
requested within the original permit application. Further, a stormwater management plan for the entire subdivision was
developed in accordance with the requirements that were in place at the time of the application submittal.

2c. If you answered "yes" to one or both of the above questions, provide an explanation of the violation(s):
3. Cumulative Impacts (DWQ Requirement)
3a. Will this project (based on past and reasonably anticipated future impacts) result in
Yes No
additional development, which could impact nearby downstream water quality?
3b. If you answered "yes" to the above, submit a qualitative or quantitative cumulative impact analysis in accordance with the
most recent DWQ policy. If you answered "no," provide a short narrative description.
We have reviewed the "DRAFT Internal Policy, Cumulative impacts and the 401 Water Quality Certification and Isolated
Wetland Programs" document prepared by the NC Division of Water Quality on April 10, 2004, version 2.1. The draft
states that most residential subdivisions are unlikely to cause cumulative impacts. This residential project does not meet
any of the three criteria of private projects that can clearly result in cumulative impacts. This development is relatively
small in nature, has no commercial component associated with it, is within a primarily residentially developed landscape
and therefore, the utility infrastructure (i.e. water and electricity) are already in place to service the proposed
development. This residential development will not affect regional growth patterns. We anticipate that you will advise us
if a qualitative or quantitative impact analysis is required.
4. Sewage Disposal (DWQ Requirement)
4a. 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 project will tie into an existing sewage treatment facility in the area. The City of Raleigh will ensure that its capacity is
not exceeded.

Approval of 401 Water Quality Certification and Authorization Certificate per the Neese River
Buffer Protection Rules (15A NCAC 210.0233) with Additional Conditions - REVISED
Dear Mr. Reiter:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 0.0977 acres of 404/wetland (0.0947 acres permanent impact, and 0.0030
acres temporary impact), 110 linear feet of perennial stream, and 7,180 square feet of Zone 1 Neuse Riyer
basin protected riparian buffers and 4,605 square feet of Zone 2 Neuse River basin protected riparian
buffers, as described in your application dated February 28, 2008, and received by the Division of Water
Quality (DWQ) on March 28, 2008, with additional information received by you on July 16, 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) 3699 and 3705
(GC3699) and (GC3705). The Certification(s) allows you to use Nationwide Permit(s) NW 12 and
NW29, respectively, when issued by the US Army Corps of Engineers (USACE). This Certification
replaces the Certification issued to you on July 31, 2008. 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 2k.0506 (h). This approval requires you to follow the conditions listed in the attached
certification and any additional conditions listed below.

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 aod 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
Qa: / /www.ncdot.orW doh/ operationsBMP „�t►anual /dnwnlnA�t�wm Manualpdfl
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

Ounaloe Land Developers, LLI;
Page 3 of 5
August 5, 2008
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 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.
Therefore, you must provide plans with adequate details that indicate that the current stability of the
stream will be maintained or enhanced. You must receive written approval from this Office for the
above plans before the culvert(s) is installed. Culvert(s) must be installed according to approved
plans.
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 Certfflcate 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 July
16, 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.

Buffaloe Land Developers, LLC

August 5, 2008
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
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.
7. Stormwater Management Plan Implementation Procedures (No Further Approval Needed)
• The approved SMP must be constructed and operational before any permanent building or
other structure is occupied at the site. If a development is phased, then the approved SMP for
each future phase must be constructed and operational before any permanent building or other
structure associated with that phase is occupied.
• The approved SMP as well as drainage patterns must be maintained in perpetuity.
• The SMP may not be modified* without prior written authorization from the SMP approval
authority. If the SMP falls under another state stormwater program, then a copy of the
approval letter and the modified SMP must be submitted to the 401 Oversight/Express Unit
prior to the commencement of the modifications.
8. 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;
9. 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 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 1 SOB 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.
