ITEM B.3a
B.3a. Describe the existing conditions on the site and the general land use in the vicinity
of the project at the time of this application:
Project is at rear of a residential lot in a natural wooded area which has been left natural
by the homeowner in order to retain the natural beauty of the property. The homeowner's
residence is built on the front two fifths of the lot which is landscaped, with the back
three fifths purposely left natural and wooded. There is a natural drainage ditch running
across the width of the lot near the very rear of the lot in the wooded area. Prior to its
erosion, the natural ditch was about 1 1/2. feet wide and 1 'h feet deep running roughly east
ha west in a fairly straight path from side to side. During its 2005-2007 Guilford College
Road widening project, NC DOT installed a 24 inch stormwater drainage pipe from a low
point on the widened road about 300 feet east of homeowner's lot to a discharge point 12
feet from the back eastern edge of homeowner's lot. After homeowner's complaints, NC
DOT also installed a so-called energy dissipater basin about 10 feet in diameter and filled
with one layer of rip-rap. Discharge from the NC DOT 24 inch pipe is calculated by NC
DOT to be 18,5 cfs and 7.3 fps based on a 10-year storm. The so-called energy dissipater
blew out in storms sometime before 2009. During high-intensity rainfall events, the
discharge from NC DOT's 24 inch pipe has caused scour at the pipe outlet and severe
erosion of the natural drainage ditch crossing the rear of the homeowner's lot. The
natural path of the ditch was also diverted during erosion such that there is now a large
serpentine curve about two-thirds of the way (east to west) across the back of the lot. A
deep gully has formed across about one-half to three-fifths of the lot (downstream side)
from head-cutting west to east. The resulting gully varies in width and depth, reaching as
much as eight feet in width and nearly 6 feet in depth in several places in the western half
of the gully. Several very large trees at or near the now eroded ditch have been severely
damaged and probably will not survive, although the root ball of one near the eastern
edge of the property is clearly retarding erosion at that end of the ditch. See also attached
surveyor's plat (showing ditch location on lot before erosion began) and sketch showing
lot with currently eroded ditch (now really mostly a gully).

ITEM B.3d
B.3d. Explain the purpose of the proposed project:
The project purpose is to remediate severely eroded portion of natural drainage ditch by
restoring property with as little permanent economic and environmental damage to
owner's property as practicable while preserving the character of its natural wooded area
as much as practicable without encroaching on adjoining properties owned by others and
without causing consequences of the NC DOT's 24 inch pipe discharges to be any more
damaging to others downstream than they were before project construction. The project
must also provide a long-term stormwater conveyance capability for discharge from the
NC DOT's 24 inch pipe at the rates calculated by NC DOT based on a 10-year storm.

RE
ITEM B.3e
B.3e. Describe the overall project in detail, including the We of equipment to be used:
Two basic approaches were considered - open channel lined with rip rap and buried
culvert with inlet and outlet protection. Under both approaches, the start of the
remediation would essentially coincide with the entrance to the existing 20 foot long 18
inch diameter corrugated metal pipe, with that pipe being removed because it may be
undersized for the discharges from the NC DOT 24 inch stormwater drain pipe
Installation of an open channel should, according to professional engineers consulted for
this approach, follow the path of the eroded ditch, including along the new serpentine
curve created by erosion action. Under this approach, about 110 feet of severely eroded
ditch would be cleared, an appropriate trapezoidal channel formed having 2:1 side slopes
(resulting in a maximum channel width of about 12 to 14 feet), filter fabric anchored, and
Class 1 rip-rap stone emplaced along the entire channel and its sides. This approach is not
feasible because the serpentine curve formed by the erosion is even now encroaching on
Jamesford Meadows Home Owners Association property, and the owner does not have
the right to place a rip-rap lined channel partially on someone else's property.
Furthermore, this approach would permanently remove a considerable amount of
attractive natural property (in order to create the requisite trapezoidal channel with 2:1
side slopes) from any further use or enjoyment by the owner and also thereby diminish
the economic value of the property. Therefore, this approach was not chosen for the
proposed project.
The selected approach is to install a curried culvert with appropriate inlet and outlet
protection. This approach does not require encroaching on anyone else's private property
and does not remove any existing natural property from fin-ther use and enjoyment by the
owner, and also thereby does not diminish the economic value of the property any
further. Culvert analysis by a professional engineer indicates that a 24 inch diameter, dual
wall, smooth interior, corrugated plastic pipe will transmit the discharges from the NC
DOT pipe at the edge of the property satisfactorily when installed at a slope of 1% or
perhaps slightly more. An installed pipe length of about 100 feet, from the entrance point
of the existing 18 inch 20 foot culvert (which will be removed in this project) to a point
15 feet from the western lot line can best accommodate site conditions. At the new pipe
entrance, the pipe invert will be placed approximately 3640 inches below grade and up
stream from the entrance to the new 24 inch pipe, the existing ditch will be prepared to
assure that the discharge from the NC DOT pipe is gathered into the new pipe; this will
include placing Class 1 rip-rap at and on either side of the new pipe's entrance fro at least
6 to 8 feet to assure that stormwater is routed into the new pipe as well as assure the new
pipe remains stable. At the outlet of the new 24 inch pipe, a 15 foot long (at least 3 to 5
feet longer than the dissipater installed by NC DOT at its 24 inch pipe outlet) Class 1 rip-
rap channel lining on erosion matting will be installed to dissipate the discharge energy
and discourage any further degradation from erosion downstream. Since flexible pipe
culverts derive much of their strength and ability to support cover and traffic loading
from the bedding and adjacent backfill, the new pipe's foundation bed will provide
uniform support and help seat the pipe in the bedding. The 100 foot bed will be cleared
and all unsuitable material removed from the bed; crushed run rock will be used for an
approximate 6 inch foundation bed and will also be placed in alternating layers on either
side of the pipe to support the culvert to at least the spring line; backfill will then be used
to complete filling around and covering the pipe. Fill will be tamped if and as necessary.
The portion of the eroded ditch not used as the path for the new 24 inch pipe (primarily
the serpentine curve section) will be filled appropriately, and the entire disturbed area,
including along the length of the new pipe, will be stabilized and vegetated as appropriate
under the site conditions.
The equipment to be used for this proposed project includes back-hoe, front-loader, and
bobcats. Access to owner's property across Jamesford Meadows Home Owners
Association property for such equipment and for this project has already been secured.
See also attached sketches showing current and upon remediation project conditions, as
well as rip-rap cross-sectional sketch.

D 1 a Specifically describe measures taken to avoid or minimize the proposed impacts in
designing project.
Other than leaving the severely eroded gully in place, and suffer continuing severe
erosion from every rain storm - which would result in unacceptable damage to and
reduction in property value to the point of perhaps even being unable to sell owner's
home as well as continued environmental damage downstream through continued silting
from erosion - the only realistic designs were an open channel lined with rip-rap and a
buried culvert with inlet and outlet protection. As discussed under B.3e above, the open
channel approach is neither feasible nor appropriate for owner's site. The culvert design
takes advantage of the existing culvert space and, in effect, merely extends a properly
sized culvert from that location across the severely eroded path as much as possible to a
point sufficiently distant from the edge of owner's property (15 feet) to be able to install
appropriate rip-rap dissipation channel that is, in fact, longer than that installed by NC
DOT (under U.S.A. Corps of Engineers and NC Department of Environment and Natural
Resources 404 and 401 permits respectively) at its 24 inch pipe outfall. Thus,
downstream impacts caused by the NC DOT 24 inch drain pipe are not being aggravated
by the project. The new pipe also essentially follows the path of the original drainage
ditch and makes the linear path (and impact) as short as possible. This path also
minimizes the amount of soil and stream bed disturbance required to install the new pipe.
The drainage ditch upstream from the existing 18 inch 20 foot long culvert is not to be
piped; professional engineers have advised that the present ditch situation and condition
is adequate for the foreseeable futures. Thus disturbance upstream is minimized be the
project design. Finally, this design and the 24 inch pipe selected will have a useful
service life of thirty to fifty years in this type of installation, thus avoiding any need to do
any further disturbing construction at this site for the maximum period practicable.

D.1b. Specifically describe measures taken to avoid or minimize the proposed impacts
through construction techniques.
Only the smallest practicable construction equipment will be used during this project - no
large excavation equipment, dump trucks, or earth movers will be permitted on owner's
site - thus minimizing earth disturbances and environmental insult. Project construction
will take place only during dry period(s) so that conveyance of any loose soil, debris, and
the like downstream will be reduced to as near zero as practicable. The project
construction takes place within a wooded area, and barriers such as screenings, and
holding areas, etc. are not envisioned. To the extent a lay-down area is required for the
project, it will be a significant distance from the owner's site and thus, will not impact the
stream on the site. This is a very small project and special control measures typical of
large projects are neither practicable not envisioned. Disturbed soil and the area over and
around the buried culvert and inlet/outlet protection areas will be promptly stabilized and
vegetated as appropriate for the site conditions.
