RE: PCN Application Package for 0.081 acres (3,518 square feet) of Buffer Impacts and 302 linear feet of
Stream Impacts for Stream Bank Stabilization along Bushy Creek in Raleigh, NC
Dear Ms. Goss;
The project consists of bank stabilization along a disturbed segment of Bushy Creek (part of the Neuse River
Basin). A short section of the creek is currently degraded and the southern stream bank has become unstable.
Erosion has extended toward an existing duplex. The southern bank has migrated within a couple feet of the
existing patios and an electrical transformer, and if left to continue, may compromise the structural integrity of the
residences. Approximately 150 linear feet of the stream has been designated for bank stabilization.
The proposed project will result in approximately 150 linear feet of permanent stream impacts (302 linear feet of
total stream impacts) and 1,556 square feet of permanent buffer impacts (3,518 square feet of total buffer
impacts). A majority of the impacts are temporary, and after construction the site will be returned to pre -
construction conditions and will be replanted with appropriate vegetation.
It is WSP's pleasure to submit this PCN application package on behalf of Wayne Miles and the City of Raleigh.
Please feel free to call at [phone] or email at [e-mail] if you have any questions or
comments.
Sincerely,
Jon Becker, EI

KINGS COURT STREAM BANK STABILIZATION
PCN SUPPLEMENTAL ATTACHMENT
08/31/2018
Along the opposite stream bank, the City of Raleigh owns an undisturbed parcel, including a
50 feet Capital Area Greenway Easement.
The contributing drainage area covers 1.32 square miles and is almost completely developed.
The online USGS StreamStats application reports 97% developed urban land, of which, 28% is
impervious. The developed urban land is a mixture of residential and commercial/industrial.
Bushy Creek is classified by NCDEQ as a class C, nutrient sensitive stream within the Neuse river
basin. Bushy Creek is subject to the Neuse River Buffer Rules.
The degrading stream banks which require stabilization are adjacent to the townhome units,
and are threatening the integrity of the townhome patios and a nearby pad -mounted
transformer. Along the bank below the transformer, power lines have been exposed as soil has
sloughed from the area. The banks have approached to within 5-8 feet of the infrastructures
and display evidence of active erosion.
The southern stream bank, adjacent to the townhomes, is occupied by mature trees including
yellow -poplar, sweetgum, and river birch. Beneath the mature canopy, there is a sparse but
diverse midstory which includes mulberry, ash, and persimmon.
The understory is dominated by an assortment of native and invasive species including:
multiflora rose, bush honeysuckle, greenbrier, blackberry, and privet. Grape vines, poison ivy,
and Virginia creeper are also abundant throughout a mixture of vine species. This assortment
of vines is strangling a few of the mature trees and threatening their health. Along the
southern stream bank (owned by the City of Raleigh) kudzu is present, along with many of the
same understory species listed above.
There is significant evidence that falling/dead trees have negatively impacted the integrity of
the stream bank, and the existing state of bank vegetation may need to be managed to ensure
the long-term stabilization of the channel banks. Photos of the existing site conditions are
included within Appendix C.
B; 3D) PROJECT PURPOSE
The purpose of the project is to stabilize a severely eroded stream bank. Continued erosion
could jeopardize the condition of the nearby townhome, as well as pose a safety risk to the
residents. The tops of actively eroding banks are visibly unstable and could fail if a live load is
applied. The banks are steep and tall enough that falling down the channel could cause
severe injury. The proposed improvements will be designed to reduce near bank stress and
provide a stable channel section. In conjunction with conventional bank stabilization
measures, a degraded/failing stormwater outfall will be rebuilt. As a secondary goal, the
methods used for bank stabilization could provide improvements to habitat, water quality, and
vegetative health and diversity.
B; 3E) PROJECT AND EQUIPMENT
The design will involve re -grading the channel banks, in conjunction with the installation of
imbricated rock bank protection and rock vanes. These modifications will be confined to two
separate sections of the stream measuring 95 LF and 55 LF respectively. The channel bed will
be impacted to the minimum extent practicable, and restored to the pre -construction
conditions.
Temporary stream flow impacts will be unavoidable, as a pump -around system will need to be
installed so that construction activity can occur in dry conditions. Construction access will
require the temporary adjustment of the stream bank near the existing parking area (see

KINGS COURT STREAM BANK STABILIZATION
PCN SUPPLEMENTAL ATTACHMENT
08/31/2018
Figure 1; highlighted in red). Temporary impacts will total 152 linear feet. Within 7 days of
completing construction requiring machinery, the stream bed will be returned to its pre -
construction elevation, and material gradation. Salvaged bed material will be utilized and will
be supplemented by new material only as needed.
The stream banks will be stabilized using imbricated rock and a stable combination of slopes
0.5:1 or flatter). Imbricated rock will be placed up to 3-4 feet in height, only as needed to
prevent the limits of grading from encroaching toward the townhome units. Due to the
pattern of the existing stream alignment, and the height of the existing bank, three (3) rock
vanes will be installed in conjunction with the imbricated rock. All rock will be designed and
installed to withstand the shear stress within the channel, and to minimize the potential for
unintended erosion.
Additionally, an 18 inch CMP outfall, discharging untreated runoff, will be replaced in a stable
location, and with the appropriate material during the bank stabilization construction. The
outfall needs to be replaced due to maintenance concerns. The bottom of the existing pipe is
corroded and failing. A sinkhole has appeared along the pipe alignment between the existing
curb inlet and the stream bank. Additionally, replacement of the pipe will allow for an
improved end condition, which will limit bank erosion and bed scour. The existing CMP is
perched and extends, entirely exposed, approximately 10 feet out of the bank.
Replacement of the CMP outfall will require removal of pavement, which will be replaced in
kind. Two manholes will be added to facilitate horizontal and vertial relocation of the 18 inch
pipe, which will result in a more stable outfall location and discharge angle.
To the maximum extent practicable, small equipment (mini -excavators, etc.) will be utilized by
the contractor, to minimize impacts to in-situ soil conditions and nearby tree roots. All heavy
equipment, and delivery vehicles will remain in the paved parking area when possible.
Q 1A) PROJECT, • MINIMIZE DESIGNED IMPACTS
Environmental impacts will be limited to bank stabilization. No significant fill will be placed in
the stream bed, aside from temporary stone/sandbags required for the pump -around. Any
permanent material will be installed solely to return the bed to pre -construction conditions,
with regards to material, elevation, and gradation. Minor modifications may be required to the
toe of the bank slopes, as the banks are rebuilt. Aside from the installation of imbricated rock,
modifications in bank geometry will also be minor, and will essentially return them to their
original, stable locations, prior to bank erosion. The channel centerline and thalweg locations
will not be modified, except as influence by the proposed rock vanes. The height of imbricated
rock walls has been minimized, so that walls are only as tall as required to daylight the
proposed stream banks at a stable slope. Additionally, the stream bank between the two
bends targeted for stabilization will be left mostly undisturbed. The banks in this area are
vegetated and fairly stable. The only activity designated for this area will be removal of
invasive/aggressive plants which threaten the health of the overstory. This work will be done
on foot to minimize impact to the stream bank and surrounding vegetation.
D; 1B) PROJECT MINIMIZE CONSTRUCTION IMPACTS
Methods of access and construction will be selected to minimize impacts to in situ soil
conditions and to existing trees. Where feasible, existing vegetation will be maintained.
Lightweight equipment will be used to prevent excessive soil compaction, and harm to
existing root mass. Approppriate erosion and sediment control measures will be utilized to
prevent sediment from entering the stream channel. All disturbed areas within the channel

PCN SUPPLEMENTAL ATTACHMENT

will be stabilized at the end of every day. All areas above the top of banks will be stabilized
within two weeks of the initial disturbance. Where feasible, management of invasive species
will be conducted on foot.
F,• 5D) DATA SOURCES; ENDANGERED SPECIES AND/OR CRITICAL HABITAT
The U.S. Fish and Wildlife Service Information for Planning and Conservation
(httr)s://ecos.fws.gov/ipac� identifies the following federal threatened and endangered species
for Wake County:
• Threatened
o NA
• Proposed Threatened
o NA
• Endangered
o Red -Cockaded Woodpecker (Picoides borealis): No suitable habitat is present in
the project area. The project will have no effect on the Red -Cockaded
Woodpecker.
o Dwarf Wedgemussel (Alasmidonta heterodon): The North Carolina Natural
Heritage Program reports no known occurrence of the Dwarf Wedgemussel
within one mile of the project area. This project will not result in permanent loss
of habitat.
o Michaux's Sumac (Rhus michauxii): No suitable habitat is present in the project
area. The project will have no effect on Michaux's Sumac.

IMPLEMENTATION SEQUENCE.
SEDIMENT CONTROL MEASURES, PUMP -AROUND PRACTICES, AND ASSOCIATED DREDGE CONSTRUCTION
SHOULD BE COMPLETED IN THE FOLLOWING SEQUENCE (REFER TO DETAIL).
1. THE CONTRACTOR SHOULD ONLY BEGIN WORK IN AN AREA WHICH CAN BE COMPLETED BY THE END
OF THE DAY. AT THE END OF EACH WORK DAY, THE WORK AREA MUST BE STABILIZED AND THE PUMP
AROUND REMOVED. WORK SHOULD NOT BE CONDUCTED IN THE STREAM DURING RAIN EVENTS.
Z SANDBAG DIKES SHOULD BE SITUATED AT THE ENDS OF THE WORK AREA AS SHOWN ON THE PLANS,
AND PONDED WATER SHOULD BE PUMPED AROUND THE WORK AREA. THE PUMP SHOULD DISCHARGE
ONTO A STABLE VELOCITY DISSIPATER MADE OF RIPRAP OR SANDBAGS.
3. WATER FROM THE WORK AREA SHOULD BE PUMPED TO A SEDIMENT FILTERING MEASURE SUCH AS A
DEWATERING BASIN, SEDIMENT BAG, OR OTHER APPROVED SOURCE. THE MEASURE SHOULD BE
LOCATED SUCH THAT THE WATER DRAINS DOWNSTREAM OF THE POND.
4. AFTERAN AREA IS COMPLETED AND STABILIZED, THE CLEAN WATER DIKE SHOULD BE REMOVED.
AFTER THE FIRST SEDIMENT FLUSH, A NEW CLEAN WATER DIKE SHOULD BE ESTABLISHED FROM THE
DEC) SEDIMENT DIKE. FINALLY, ESTABLISH ANEW SEDIMENT DIKE BELOW THE OLD ONE, AND RESUME
PUMPING TO THE APPROPRIATE END TREATMENT (VELOCITY DISSIPATOR OR DEWATERING DEVICE).
