10. Describe the overall project in detail, including the type of equipment to be used: Private
' residential community with approximately 11 lots proposed as part of the development on a
30.8-acre property. Average lot size for this development is 2 '/2 acres in size. Subdivision
road and driveway stubs have been previously constructed (see Site Plan). One stream
' crossing is considered necessary as part of the project in order to gain access to the only
buildable portion on tract 11. The proposed culvert is for a single family driveway. UT-
Norris Branch has an approximate 8.7-acre drainage area above the proposed culvert
' installation point. Predicted 25-year storm event for this site can generate a maximum
discharge of 20.3 cfs. The proposed culvert diameter is 30". Typical construction equipment
will be used to complete the road and pine installation work i.e. bulldozer, trackhoe, and
' dumptruck. A temporary sandbag stream diversion (see Diversion Detail) will be used during
pipe installation to prevent sedimentation and to provide a dry environment for the
completion of work.
' 11. Explain the purpose of the proposed work: The purpose of the work is to provide access to a
portion of the property that is cut off by the stream UT-Norris Branch. This stream runs the
¦ entire length of the nronertv with no means of access from the other side.
IV. Prior Project History
' If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
' the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
' buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules. None
V. Future Project Plans

and provide justification for the exclusion of this work from the current application. None
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
' wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
' accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
' Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
Red Fox Ridge Page 3 of 9 Environmental Consultant: ENV-ECS, Inc.

wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
' space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: A 30" by 25 linear foot culvert is
proposed to be installed for a single family driveway crossing in the Red Fox Ridge
development site in order to provide access to a portion of the site (tract 11). 25 linear feet of
channel in UT-Norris Branch will be put into pipe as part of the stream crossing (see Impact
Map). This 25' impact will be permanent in nature. As part of the installation, 3 linear feet of
channel will be sandbagged in order to divert flow around the installation site and is being
treated as a temporary impact (see Impact Map and Diversion Detail). Sandbags and a
temporary diversion ditch will be removed once the pipe installation is completed, and all of
the associated impacts to the stream bank will be mitigated with regrading and reve eg tation.
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,

1 VII. Impact Justification (Avoidance and Minimization)
1 Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
1 site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. This impact is necessary so as
1 Red Fox Ridge Page 5 of 9 Environmental Consultant: ENV-ECS, Inc.
PCN-NWP 29 August 22, 2008

to gain access to the only buildable portion of a 5'/2-acre portion of the site that is otherwise
inaccessible. Culvert placement anywhere else along the stream would either not tie effectively
into the site plan and existing road network, or placement could potentially impact wetlands in
the wide stream valley. Construction of bridge is not considered practical considering the cost of
a bridge and required approach fill as compared to the minimal impacts proposed.
The site chosen for the stream crossing will utilize the natural topography on both sides of the
stream, as there is an existing bench parallel with the proposed driveway. Proposed driveway
placement and orientation with the proposed culvert avoids several wetlands that are located
above and below proposed driveway centerline. Culvert installation will be countersunk 6" in
order to help regain aquatic components. All work will be performed in the dry by using a
sandbag stream diversion. No changes will result from proposed work to the channel elevation or
bank characteristics. Revegetation of banks will take place following stream work due to the
diveminn_
Since the stream classification for UT-Norris Branch (WS II, HOW, Tr., CA) carries water
quality conditions, the following site development components will be adhered to so as to
maintain permit condition compliance: 30' buffers will be observed on all perennial sections of
UT-Norris Branch; 25' trout buffers on all intermittent and perennial sections; erosion and
sediment control measures are to be designed for a 25-year storm event; minimum lot sizes in the
Critical Area watershed will be 2-acres and 1-acre in the WS-II watershed areas of the site; all
storm water will not be directed towards stream bodies; impervious built-up areas in the CA
watershed will not exceed 6% and will not exceed 12% in the WS-II watershed areas.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
