3. Project Description
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:
The project is located near downtown Raleigh. The area of the project site is a commercial property in which a car wash
is located. Cemetery Branch runs from south to north through the project site. Twin Tx 7' box culverts are located at the
downstream northern end of the project site conveying stormwater from Cemetery Branch under Automotive Way and
Capital Boulevard.
The watershed for the stream consists of 724 acres of urban residential and commercial parcels. The car wash is located
on the eastern side of the stream up on an elevated terrace. The car wash is surrounded by a retaining wall
approximately 10 feet above the stream floodplain. The floodplain is currently maintained grass with no woody buffer
vegetation.
The stream channel is severely degraded. The stream channel banks are almost vertical in the bends and have little
vegetation to hold them in place. The eastern bank at the beginning of the project site is actively erroding and contributing
a large amount of sediment to the stream. The existing bankfull channel has incised from 1.5 to 2 feet below the
floodplain elevation throughout the reach.
An existing storm drainage pipe system collecting water from Automotive Way discharges stormwater from a twenty-four
inch (24") diameter reinforced concrete pipe (RCP) into the right of way approximately thirty-five feet (35') from the
entrance to the box culverts. The discharge location of the existing pipe has erroded the earth cover over the existing
sanitary sewer pipe. The City of Raleigh Public Utilities Department has in the past placed paved concrete bank armor
over the easement to the toe of the stream to stabilize the easement from further stormwater erosion that could
undermine the sanitary sewer line. The outlet of the existing twenty-four inch (24") pipe is currently erroding the adjacent
soils and an unstable gully has formed from the outlet to the stream. The existing twenty-four inch (24") storm drainage
line is currently undersized. The size and slope of the existing line are factors that limit the capacity of the pipe to carry
the City of Raleigh 10-year design storm event.
3b. List the total estimated acreage of all existing wetlands on the property:
No wetlands exist within the project area.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
180 linear feet
3d. Explain the purpose of the proposed project:
The purpose of this project is to stabilize the stream to prevent further sediment deposition into the stream. The
stabilization will include providing a bankfull bench along the stream so that storm events greater than bankfull will have
access to it. The project will also include revegetation of the stream bank and most of buffer Zone 1. The re-vegetation
will introduce native grasses and woody vegetation for long-term stabilization. The project will also upgrade the existing
twenty-four inch (24") storm drainage pipe to handle the standard City of Raleigh 10-year design storm. The existing pipe
location will be improved to stabilize the outlet, transition the flow to the stream, and relocate the discharge as far from the
stream as possible. The existing pipe currently discharges into Zone 1 of the stream buffer.
Page 4 of 12
PCN Form - Version 1.3 December 10, 2008 Version
3e. Describe the overall project in detail, including the type of equipment to be used:
The project will consist of regrading the floodplain and sloping back the existing banks of the channel to a stable slope. A
rock structure will be placed at the beginning of the project to maintain the channel's vertical elevation and assist in
protecting the bank at the outside bend at the southwestern comer of the car wash. The stream's banks will be seeded,
matted, and replanted with woody vegetation. The floodplain within planting Zone 1 will also be seeded and planted with
woody vegetation. Planting Zone 2 includes buffer Zone 2 and any disturbed areas beyond the buffer, will be planted with
grasses to match the existing conditions. With the proposed project a new junction box and twin (2) thirty inch (30")
diameter RCP pipes will be installed to replace the existing undersized twenty-four inch (24") diameter pipe.
The new twin thirty inch (30") diameter pipes have been designed to be in compliance with the standard City of Raleigh
10-year storm event pipe capacity. Two pipes are required due to the pipe slope. The pipes have been extended to a
minimal length to discharge as far as possible away from the stream in Zone 2 of the buffer and onto the modified
floodplain. The pipes will discharge onto the floodplan and onto a riprap energy dissipator that will transition the water to
the exisiting channel.
Alternatives were investigated as to the location and pipe upgrade options. The limitations of the existing power pole,
limited right of way width, and the adjacent sanitary sewer line location and elevation were factors in the final relocation
plan shown on the construction plans. The location and elevation of the existing junction allow for the new pipes to be
installed above the existing sanitary sewer within the permissible minimal City of Raleigh clearence of six (6") inches.
Because of the limitations of the property a level spreader is not possible for this relocation. The existing 24 inch concrete
pipe due to the constraints at the right of way will be left in place and filled.
The equipment that would most likely be used in this project is earth moving equipment and various other support
apparatus. Heavy equipment may include hydraulic excavators, compactors, bulldozers, skidsteer loaders, and material
hauling apparatus such as a dump truck. This type of equipment will be used for excavation and placement of materials
for the project. The construction equipment will enter off of Automotive Way at the north west comer of the property and
from the carwash at the property line with 104 Plainview Avenue as shown on the plans. The construction equipment will
not cross the stream at any time, all work will be completed from the top of the stream banks.

6i. Comments: Buffer impacts will be for construction access and grading of benches. Zone 1 is currently grassed. With the
proposed project this zone will be mostly re-vegetated with woody species which will improve the current conditon. Rip rap will
be placed from the end of the new 30 inch storm drainage pipes to the stream and at the end of the existing concrete flume to
dissipate energy and transition the storm water flows to the stream.
D. Impact Justification and Mitigation
1. Avoidance and Minimization
la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
This project is necessary to stabilize the current stream banks and to eliminate the sediment deposition currently occuring due
to erosion. The proposed project design will re-introduce vegetation back to the stream banks and Zone 1 of the buffer, thus
improving the existing conditions. The existing channel pattern and profile will be utilized in this project. Floodplain benching
minimizes the impacts to the stream and yet allows for larger than bankfull storm events to access the floodplain. The existing
storm drainage system impacts were minimized and stabilized with the relocation of the piped discharge from buffer Zone 1 to
Zone 2.The discharge pipes will dispose flow onto the floodplain and into a stable transition to the stream.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The construction of the project will occur from the top of both banks. Construction equipment will not cross the channel.

1.0 Stone
1.1 Description
The work covered by this section consists of placing and maintaining an approved stone
to be utilized as construction entrance, energy dissipater, and for use in other locations as
shown on the plans or as directed by the Engineer.
1.2 Materials
Stone for Boulder, Aggregate No 5, No. 57 Stone and Class B, A, I and II stone shall
consist of blasted stone or other stone approved by the Engineer. The stone shall be
sound, tough, dense, resistant to the action of air and water, and suitable in all other
respects for the purpose intended.
The following materials shall meet the requirements of Division 10 of the 2002 North

Rip Rap Class I Article 1042-1
Rip Rap Class 11 Article 1042.1
While no specific gradation is required, the various sizes of the stone shall be equally
distributed within the required size range. The size of an individual stone particle will be
determined by measuring its median dimension. Fifty (50) percent of the stone mix shall
be the median stone size. The minimum stone size shall make up no more than 25% of
the mix.
Acceptance Criteria for Stone and Riprap
Class Minimum Average 50% of mix Maximum
A 2 inches 4 inches 6 inches

Engineer, to the thickness, widths, and lengths as shown on the plans or directed by the
Engineer. All stone shall be placed to form an in-stream structure or channel lining in
accordance with the plans neatly and uniformly with an even surface and shall meet the
approval of the Engineer.
Provide sites for aggregate stockpiles that are cleared m grubbed and cleaned with a firm,
smooth, and well drained ground surface. Maintain a cover of at least 3' of aggregate
over the ground surface to avoid the inclusion of soil or foreign material. Operate truck
or to the equipment on a stockpile in an acceptable manner. Separate stockpiles of
different types or sizes of aggregates and stone to prevent mixing.
1.4 Method of Measurement
The quantity of stone and aggregate to be paid for will be the actual number of tons that
has been incorporated into the work, or has been delivered to and stockpiled on the
project as directed by the Engineer. Stone and aggregate that has been stockpiled will not
be measured a second time. The stone and aggregate will be measured by being weighed
in trucks on certified platform scales or other certified weighing devices. The Contractor
shall furnish all documentation of certified weight certificates.
1.5 Basis of Payment
The quantity of boulders measured as provided above, will be paid for at the contract unit
price per ton for, Coarse Aggregate No._", or "Class _ Stone". Such price and
payment will be full compensation for all work covered by this section including but not
limited to furnishing, weighing, stockpiling, re-handling, placing, and maintaining the
boulders and disposal of any materials not incorporated into the project if directed by the
Engineer.

others to resist rolling and shall be individually picked for use as specified in the plans.
Boulders shall be relatively flat on either side in the same dimension, preferably the long
dimension. The Engineer shall approve the maximum dimension of all boulders.
2.4 Construction Methods
The Contractor shall place stone, in locations shown on the plans or as directed by the
Engineer, to the thickness, widths, and lengths as shown on the plans or directed by the
Engineer. All stone shall be placed to form an in-stream structure or channel lining in
accordance with the plans neatly and uniformly with an even surface and shall meet the
approval of the Engineer.
The quantity of stone to be paid for will be the actual number of tons that has been

The blanket shall be of consistent thickness with the coconut fiber evenly distributed over
the entire area of the mat. Coconut Fiber Blankets will only be used in locations specified
by the Engineer. Locations will be on all disturbed streambanks prior to turning the
streamflow into the newly constructed channel. Other problem areas may also require the
placement of coconut fiber blankets.
Materials
Coconut fiber matting shall be provided to meet the snecifientiom nmviripii hPlnw

Recommended Flow 11 feet/second 3.35 m/s
Size 6.6 x 164 feet 120 SY) or 100 SM
"C" Factor 0.002
Stakes will be wooden stakes 12 in. (300 mm) in length with a notch cut 1 in. (25 mm)
from the top. These stakes shall be used to stake the matting along the slopes. Wooden 3
ft. stakes spaced approximately 4 ft. apart shall be used to secure the matting at the toe of
the slope. The toe stakes shall have a minimum 1-inch by 1-inch cross-section and shall
be designed so that the matting can not slide past the exposed end of the stake.
Construction Methods:
Provide a smooth soil surface free from stones, clods, or debris that will prevent the
contact of the matting with the soil. Place the matting immediately upon final grading.
Take care to preserve the required line, grade, and cross section of the area covered. All
cut slopes shall be stabilized at the end of each working day with erosion control matting.
Apply fertilizer, seed, lime, and straw mulching prior to installing the matting.
Unroll the matting and apply without stretching such that it will lie smoothly but loosely
on the soil surface. Bury the top slope end of each piece of matting in a narrow trench at
least 6 inches (150 mm) deep and tamp firmly. Where one roll of matting ends and a
second roll begins, overlap the end of the upper roll over the buried end of the second roll
so there is a 6 inches (150 mm) overlap. Construct check trenches at least 12 inches (0.3
m) deep every 50 feet (16 m) longitudinally along the edges of the matting or as directed
by the Project Engineer. Fold over and bury matting to the full depth of the trench, close
and tamp firmly. Overlap matting at least 6 inches (150 mm) where 2 or more widths of
matting are installed side by side.
Place stakes across the matting at ends, junctions, and check trenches approximately 1
foot (90.3 m) apart with notch facing upslope. Place stakes along the outer edges and
down the center of each strip of matting 3 feet (1 meter) apart. Place stakes along all
lapped edges 1 foot (0.3 m) apart. Refer to details in the plan sheets.
The Engineer may require adjustments in the trenching or staking requirements to fit
individual site conditions.
Basis of Payment
The quantity of "Erosion Control Matting/Coir Matting" measured as provided above
will be paid for at the contract unit price per square yard for "Erosion Control
Matting/Coconut Fiber (Coir) Blanket" and shall include all work and materials required
in this section. Payment for staples, stakes, and twine will be included in the contract unit
price for "Erosion Control Matting".
Payment will be made under:
