WETLAND/BUFFER MAPS: A jurisdictional wetland/stream delineation
was performed by The John R. McAdams Company on March 17, 2006 and
field verified by Mr. Jamie Shern (USAGE representative) on November 9,
2006. A Neuse River Stream Buffer determination was issued by Mr. Eric Kulz
on February 12, 2007 (attached DWQ Project No. NBRRO 06-317 letter).
BUFFER IMPACTS: The entire project was designed to avoid and
minimize impacts to wetlands, streams, and riparian buffer areas while
utilizing the remaining areas for development of the site. There are no
jurisdictional stream or wetland impacts proposed with the project. There is
one roadway span, pedestrian bridge span, and several areas of buffer
encroachment associated with the installation of the sanitary sewer. All
proposed stream buffer impacts fall under the "allowable use" category in the
Neuse River stream buffer table of uses, with no mitigation required. There is
a network of roads to access the approximately 148-acre project site; however,

the development plan proposes only one roadway stream buffer impact
totaling 0.27-acre and less than 150 linear feet of impact associated with the
installation of the entrance road, which is an allowable use (sheets 2). The
proposed road will span the stream feature close to 90 degrees and will have
abutments 10-feet from the stream's top-of--bank. A pedestrian bridge is
proposed instead of a road in the northwest quadrant to encourage walking to
the retail areas adjacent areas of the site, and will impact (sheet 1). A majority
of the proposed sewer corridor impacts are located within the Zone 2 of the
Neuse River Buffers (sheets 3, 4, and 5). There is one proposed sewer line that
is to be directionally bored under stream feature "B" close to 90 degrees, and
will have a maintenance corridor through the buffer (sheet 4). All
encroachments into the Neuse River Buffers associated with the installation
and maintenance of the sewer line corridor fall under the "allowable use"
category in the Neuse River stream buffer table of uses. Proper sedimentation
and erosion control measures will be implemented during the construction of
the project.
SUMMARY OF PROPOSED BUFFER IMPACTS:
IMPACT SHEET # ZONE 1 ZONE 2 USE
1 -Pedestrian bridge 0.02 ac. 0.02 ac. Allowable
2 -Roadway (981f) 0.15 ac. 0.12 ac. Allowable
2 -Sewer 25 s.f. Allowable
3 -Sewer 0.02 ac. Allowable
4- Sewer 0.04 ac. 0.11 ac Allowable
5 -Sewer 0.08 ac. Allowable
TOTAL 0.21 ac. 0.35 ac.
LEVEL SPREADERS: A series of 6 level spreaders are to be installed to
the current BMP manual for Phase 1 of the project. Drainage calculations,
outlet velocities, pictures, and location descriptions are provided with the level
spreader exhibits. Executed Operation and Maintenance exhibits are also
enclosed for each of the devices. As stated previously, Phase 2 is currently
only proposed and may not be built for several years. We will provide the
level-spreader documentation for Phase 2, once it come on-line. There are no
401 impacts associated with the site, so a formal stormwater plan is not
require to be submitted to DWQ, however the site is to be reviewed by the
Town of Wake Forest for stormwater management.

VII. Impact Justification (Avoidance and Minimization)
Expected pond surface area:
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
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.
The entire project was designed to avoid and minimize impacts to wetlands, streams, and riparian
buffer areas while utilizing the remaining areas for development of the site. There are no
,jurisdictional stream or wetland impacts proposed with the project. There is one roadway span,
pedestrian bride span, and several areas of buffer encroachment associated with the installation
Page 9 of 13
of the sanitary sewer. All proposed stream buffer impacts fall under the "allowable use"
category in the Neuse River stream buffer table of uses. There is a network of roads to access
the approximately 148-acre project site; however, the development plan proposes onl.~one
roadway stream buffer impact totaling 0.27-acre and less than 150 linear feet of impact
associated with the installation of the entrance road, which is an allowable use (sheets 2 . The
proposed road will span the stream feature close to 90 degrees and will have abutments 10-feet
from the stream's top-of--bank. A pedestrian bridge is proposed instead of a road in the
northwest quadrant to encourage walking to the retail areas adjacent areas of the site (sheet 1~
majority of the proposed sewer corridor impacts are located within the Zone 2 of the Neuse River
Buffers (sheets 3, 4, and 5). There is one proposed sewer line that is to be directionally
across stream feature "D" close to 90 degrees, and will have a maintenance corridor through the
buffer (sheet 4). All encroachments into the Neuse River Buffers associated with the installation
and maintenance of the sewer line corridor fall under the "allowable use" category in the Neuse
River stream buffer table of uses. Proper sedimentation and erosion control measures will be
implemented during the construction of the project.
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
Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o. enr.state.nc.us/ncwetlands/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
Page 10 of 13
description of the current site conditions and proposed method of construction: Please attach
