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 existing.l8" CMP was not
capable of conveying upland area drainage if the land were to be developed. Twin 36" RCP's
were required by the City of Greensboro to avoid potential future drainage problems on an
NCDOT roadway. This requirement was not waived despite requests to reuse the existing_18"
CMP drainage pipe.
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.
Page 9 of 12

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/strm~ide.html.
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
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed:

Overall Project Summary
Stewart Mill Road Improvements
CPT Engineering Proj. # 401-04
11/28/2007
In September 2007 improvements to Stewart Mill Road (S.R. 1324) were begun
as part of a single family subdivision project - Terrapin Ridge. CPT Engineering and
Surveying, Inc. was hired by Jeff Eells and Dick Burditt (now Terapin Ridge, LLC) to
design and permit this subdivision as well as any required roadway and utility
improvements. The project received approval from various regulatory authorities in
August 2007 and began construction in September 2007and is currently nearing
completion of the first phase of construction. First phase construction includes
improvement of Stewart Mill Road (S.R. 3124), and construction of 42 single family
homes with all required roadway and utility improvements on a 43.5 acre site.
Several regulatory agencies are involved with the planning and construction of
this project. They include Guilford County planning and inspections, the City of
Greensboro, the NCDOT, the USACE and the NC DWQ. CPT Engineering and its
subcontractors have been in contact with all of these agencies.
Stewart Mill Road (S.R. 3124) is the only access road leading to the construction
site. This roadway was required to be paved along the entire length of the property
frontage (1100 LF) as a condition for City of Greensboro plan approval. Since the site
itself is some distance from the nearest paved roadway, this made paving only the
frontage section of Stewart Mill Road impractical. This roadway is one of the
unimproved roadways scheduled to be paved at an undetermined time as part of the
NCDOT unimproved roadways paving project. It has been scheduled to be paved on
more than one occasion, but has always been delayed due to other roads being in greater
need of repair. Due to the rest of the roadway between the project site and Mount Hope
Church Road being delayed for improvements by NCDOT for the foreseeable future, the
developers elected to improve an additional 835 feet of this road to NCDOT standards at
their own substantial expense in order to better serve the access needs of potential
residents as well as local residents who already used the road.
Several improvements were made on Stewart Mill Road. They include both
roadway and utility improvements. An 8" ductile iron water line was extended from a
main on Mount Hope Church Road as a City of Greensboro requirement. The water line
extension required a crossing under Little Alamance Creek, which was successfully
permitted by ESI, inc. under USACOE action IDSAW-2007-02092-241 Nationwide 12
permit dated July 12, 2007.
The roadway was asphalt paved per NCDOT specifications. An 11" stone base
was overlaid with 2 inches of asphalt. Shoulder ditches were improved or constructed
where needed. Concrete curb and gutter was added along one side of the roadway as part
of the City of Greensboro's plan approval requirements. From conversations with a local
landowner, the roadway routinely overtopped during intense rain events and such
improvements were overdue.
As a plan approval condition, the City of Greensboro required any existing
roadway drainage pipes to be upsized to account for future upland development if
1

necessary. Calculation of the potential runoff (using City of Greensboro's criteria)
draining to these areas revealed that the existing 15" CMP would be too small if the
upland property were developed. New pipes were sized according to the City of
Greensboro's drainage design criteria for headwalls. The single existing 15" CMP was
replaced with NCDOT spec headwalls and twin 36" reinforced concrete pipes (RCP's).
In October of 2007, a site inspection by DWQ revealed that impacts to an
intermittent stream channel at the location of the previously existing CMP had not been
properly permitted. A notice of violation was mailed to Dick Burditt, one of the two
developers which formed Terrapin Ridge, LLC. Upon notification, Terrapin Ridge, LLC
notified CPT Engineering and subsequent contact with Sue Homewood of DWQ and
Andy Williams of USACOE was begun.
Mr. Williams cited by phone that a USACOE 404 Nationwide 14 permit could be
issued in order to permit the additional 36 feet of impact to the intermittent stream caused
by the installation of the pipes, headwalls and twin 36" RCP's. Mr. Williams also advised
that a state DWQ 401 General Water Certification would also be required. This was
verified via phone with Sue Homewood of the Winston-Salem NCDENR office. A PCN
is therefore being submitted for an after the fact Section 404 Nationwide 14 permit, and
the required Section 14 general water quality certification.
The impact area where the notice of violation occurred is some 900 feet away
from the site itself, but since the roadway improvements are an integral part of the overall
development some background on the development site itself is warranted. The
development site itself is a 43.5 Acre tract. It was formerly a farm with rolling pasture
land and areas of dense hardwood outside the pasture area. This is also typical of the
surrounding areas. Impervious area prior to development was 0.15 Acres or
approximately 0.34%. The developers have preserved as much of the existing forested
areas as possible by minimizing lot grading on the site and keeping roadways as close to
existing grade as possible while achieving minimum accepted roadway design standards.
Lot sizes range from a minimum of 7,902 SF to a maximum of 13,419 SF with the
majority of the lots being larger than 9,000 SF. There will be 421ots in the first phase and
43 lots in the second phase. Roadways inside the site will consist of asphalt pavement
with curb and gutter as required per City of Greensboro standards. Houses will be single
family with an average footprint of 1500 SF. and a single concrete driveway. Impervious
surface area calculated for phase I will be 8.71%. Impervious area after phase 2 is built
will be around 16% if the plan is approved by Guilford County as it is currently laid out.
(Please see attached supporting calculations).
An isolated wetland pocket does exist on the site in the area of the second phase.
It is located in an area planned for open space dedication to the City of Greensboro
between future lots 32 and 33. It is 0.06 acres in size, and has been field located after
being field flagged by the project environmental consultant ESI, Inc. It will not be
impacted by the first phase construction activities, and can likely be avoided in the
second phase through careful planning, roadway design, grading, and affective erosion
control measures. Should an impact be required due to some unforeseen aspect of phase 2
plan approval and require impacts which trigger a DWQ and USACOE review, the
proper permits will be submitted to the NCDWQ and USACOE well in advance of
construction.
