M. Project Information
Attach a vicinity map clearly showing the location of the property with respect to local
landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no larger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.
1. Name of project: 1320 Onslow Road Stream Stabilization Project
2. T.I.P. Project Number or State Project Number (NCDOT Only): N/A
3. Property Identification Number (Tax PIN): 0783.08 98 8349
4. Location
County: Wake Nearest Town:Raleigh
Subdivision name (include phase/lot number): Kentwood Subdivision / Lot 200
Directions to site (include road numbers, landmarks, etc.): From downtown Raleigh, go
west on Western Boulevard. Take a left turn (heading south) onto Kent Road, then
take a right turn (heading west) onto Garland Drive, then take a left turn (heading
south) onto Chaney Road. House is located at the intersection of Chaney Road and
Onslow Road.

6. 78 deg 41 min 49 sec (Note - If project is linear, such as a road or utility line, attach a sheet that separately
lists the coordinates for each crossing of a distinct waterbody.)
7. Property size (acres): 0.66 acre (deeded acreage)
8. Nearest body of water (stream/river/sound/ocean/lake): Bushy Branch which is a
Tributary to Walnut Creek
9. River Basin: Neuse River Basin
(Note - this must be one of North Carolina's seventeen designated major river basins. The
River Basin map is available at http:/%h2o.enr.state.nc.us/adrnin/maps/.)
10. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The site is a single family lot in a developed subdivision
near the NC State Campus in Raleigh. The existing home on this property was built in
Page 6 of 14
1993. It is on a 0.66-acre lot. Other houses in the neighborhood are generally on 0.5-
acre to 1.0 acre lots. The land use is zoned R-4 (0.25-acre residential), but the houses
are situated on the lots such that further subdivision of the lots would not be practical.
The lot for 1320 Onslow Road slopes from southwest to northeast toward Bushy
Branch near the front of the property. For the driveway, house, garage and back deck,
the total impervious surface area for this property is approximately 5,000 square feet
which is approximately 17.4 percent of the property's deeded acreage of 0.66 acre. The
stream through this property is located in a bend. The stream in this area is
experiencing severe erosion particularly on the outside of the bend. The stream
classifies as a G4 stream. The stream is entrenched with bank height/bankfull height
ratios approaching 2.5. The stream morphological data generated from the
classification cross section at a riffle generated the following values: Wbkf=22.4 ft.,
dbkf=2.3 ft, Abkf=52 sq. ft., W/D=9.7, ER=1.24, and 5=1.36%. The North Carolina
70 cfs. Th
square miles and is located in an almost fully built out urban area with residential and
commercial development. The City of Raleigh Bushy Branch Basin Study predicted
the 2 year discharge, under full build out conditions, to be approximately 900 cfs., at
this location. Bankfull conditions measured in the field predict the stream discharge at
bankfull to be approximately 530 cfs. Velocities in the channel potentially range from 7
fps. to 10 fps., for bankfull to storm events as large as the 100 year return period. The
banks are currently almost vertical with little woody vegetation. There are trees on the
banks that have fallen or are leaning into the channel. The northern bank in the
outside of the bend is experiencing severe undercutting. Tree roots are becoming
exposed as the bank is being eroded further.
11. Describe the overall project in detail, including the type of equipment to be used:. The
proiect will consist of stream bank stabilization along both banks of a 125 foot length of
Bushy Branch. The work will be contained to the property located at 1320 Onslow
Road. Because of the entrenched nature of the stream and the high velocities, a more
structural approach is required to stabilize the banks. The southern stream banks on
the inside of the bend are fairly vertical and are proposed to be laid back to a 2:1 slope.
The toe at the upstream end of the proiect has significant bedrock. However two areas
are proposed to be stabilized with Class 11 Rip Rap. The first is a transition between
two bedrock segments and the second is at the downstream end where the stream
narrows down and becomes restricted. A portion of the southern bank where a point
bar is forming will not require toe stabilization only bank reshaping. The northern
bank forms the outside of the stream bend and is currently experiencing severe erosion
at the toe and on the near vertical banks. In this area Class H Rip Rap will be required
at the toe to a vertical bankfull height of three feet. The banks will be sloped back to a
2:1 slope as shown on the plans. In all areas where the bank is to be reshaped, rooted
plant plugs will be planted to re-vegetate the stream banks. The equipment that is
proposed to be used on this project is a dump truck, loader, and track hoe. The work is
proposed to be completed from the northern bank. The only access to the southern side
of the stream is over a common bridge located on the adiacent property.
Page 7 of 14
12. Explain the purpose of the proposed work: The purpose of this project is to address
severe stream bank erosion at 1320 Onslow Road, Raleigh NC. The proposed proiect
was requested by the property owner to the City of Raleigh. This project qualified for
funding with the City of Raleigh Storm Drainage Policy and is currently being designed
and permitted by the City for construction. The proiect will stabilize the channel
banks, improve the channel-eroded dimensions, and provide for a better vegetative
buffer on the stream banks.
IV. Prior Project History

V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
None anticipated.
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, permanent
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must be shown on a
delineation map, whether or not impacts are proposed to these systems. Wetland and stream
evaluation and delineation forms should be included as appropriate. Photographs may be
included at the applicant's discretion. If this proposed impact is strictly for wetland or stream
mitigation, list and describe the impact in Section VIII below. If additional space is needed for
listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: The proposed project will
impact approximately 125 linear feet of stream bank. The impacts will be the
placement of rip rap at the bank toe to a bankfull height of 3 feet, placement of fill to
re-establish bank slope, and sloping of the current vertical banks to a 2:1 slope. No
wetland impacts are anticipated for this site. Erosion control measures will be installed
such as silt fence and a temporary check dam to contain sediment on site.

VII. Impact Justification (Avoidance and Minimization)
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.
This vroiect is limited to a stream length of 125 feet that has qualified for the City of
Raleigh assistance program for severe erosion problems. The stream is confined
horizontally by a road to the north and the house and driveway to the south. Onslow Road
is approximately 45 feet from the too of the northern bank, and the existing driveway
ranges from 10-25 feet from the ton of the southern bank. Therefore opportunities to use a
priority one or two restoration approach are not practical. A priority 4-restoration
approach was taken to focus on the stabilization of the existing banks along this small
reach. Alternatives were considered to limit the amount of riprap placed on the channel
Page 10 of 14
banks. However due to the large velocities in the stream, stone was required to provide
sufficient stabilization of the toe and bank for many different storm events that will be
confined within this channel. Bioengineering methods were not chosen because they would
not be as effective in withstanding the velocities. The riprap length along the stream bank
was minimized as much as possible in the construction plan. Wherever possible the riprap
toe was tied into existing bedrock and stable sections. Rooted plant plugs are incorporated
into the project to provide additional vegetation along the stream channel, thereby
enhancing the riparian buffer. The project is funded partially by the property owner and
partially by the City of Raleigh. Funding for this project has been approved by the City
Council and therefore repairs were required to fall within these funding limits. Therefore
funds also were a limiting factor for this project. The contractor for this project will be
required to complete the construction from the north bank limiting impacts to the existing
buffers. No stream access for equipment or crossings will be allowed in this project to
minimize impacts to the stream.
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 March 9, 2000, 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 NCWRP 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
htt tL :.; /h2 o. enr. state. nc. u s/ncwetl ands/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,
Page 11 of 14
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.
N/A
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of
