Dear Mr. Dawson:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 200 feet of streams and 10,000 square feet (ft) of protected riparian buffers
for the purpose of a streambank stabilization at the subject property, as described within your application
dated August 1, 2005 and received by the N.C. Division of Water Quality (DWQ) on August 3, 2005.
After reviewing your application, we have decided that the impacts are covered by General Water Quality.
Certification Number 3495 (GC3495). The Certification allows you to use Nationwide Permit 13 when
issued by the US Army Corps of Engineers (USACE). This letter shall also act as your approved
Authorization Certificate for impacts to the protected riparian buffers per 15A NCAC 2B .0233. In
addition, you should obtain or otherwise comply with any other required federal, state or local permits
before you go ahead with your project including (but not limited to) Erosion and Sediment Control, and
Non-discharge regulations. Also, this approval to proceed with your proposed impacts or to conduct
impacts to waters as depicted in your application shall expire upon expiration of the 404 or CAMA
Permit.
This approval is for the purpose and design that you described in your application. If you change your
project, you must notify us and you may be required to send us a new application. If the property is sold,
the new owner must be given a copy of this Certification and approval letter and is thereby responsible for
complying with all conditions. If total fills for this project (now or in the future) exceed one acre of
wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A
NCAC 2H.0506 (h). This approval requires you to follow the conditions listed in the attached
certification and any additional conditions listed below.
The Additional Conditions of the Certification are:
1. Impacts Approved
The following impacts are hereby approved as long as all of the other specific and general
conditions of this Certification (or Isolated Wetland Permit) are met. No other impacts are
approved including incidental impacts:

8. River Basin: Neuse River Basin
(Note - this must be one of North Carolina's seventeen designated major river basins. The

Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The stream is within the developed Heathrow Subdivision,
within Durant Trace in North Raleigh. The segment of the stream that is included in this
12Miect begins at the outlet of twin 36-inch RCP storm drainage pipes that stormwater
under Deanwood Drive. Just downstream of the 36" culvert outlets a 24-inch RCP enters the
stream dischargiLig stormwater collected from approximately 2000 linear feet of Deanwood
Drive and Wilder Cliff Street. A second 18" storm pipe enters the stream approximately
midway within the repair area. At the downstream end of the project the study tributary:
entering from the soutk joins with two other tributaries, from the east and north, and enters
twin 66 -inch pipes that carry the stormwater under Cub Trail. The stream repair project
area is located on the southern stream beginning approximately 30 feet downstream of the
twin 36" pipes and continuing for a distance of approximately 200 linear feet to the headwall
of the twin 66" pipes. The existing stream is currently experiencing severe erosion.
espy in the lower two thirds of the repair area. The existing 66" pipes were most likely
constructed much lower than the natural channel when the subdivision was developed. The
siomificant lowering of the channel at the outlet end at the 66" pipes has caused a head cut to
proceed upstream. The channel has deepened and widened producing a large volume of
sediment input into the stream system. Currently the stream is at a made that averages
approximately 4.5%. With these steep slopes the velocities that can be expected could range
from 6 to 9 ft/sec. The Wake County Soil Survey classifies the soils in the area as Worsham
Sandy Loam. Sandy loam soils have a non-erosive velocity of 2.5 ft/sec. There is currently
Class I riprap in the channel that was placed in an effort to slow down the current erosion.
There is no woody vegetation on the stream bank or in the buffer. The site is currently
mowed to the top of bank. There is little to no base flow in the channel. This channel
primarily conveys storm water flows.
10. Describe the overall project in detail, including the type of equipment to be used: The
project will consist of stream bank stabilization for approximately 200 feet. The existing
stream profile will be utilized in the design and the bankfull channel dimensions will be
adjusted to provide for low and bankfull flows. A bankfull bench will be excavated to a
minimum width of 4 feet on both sides of the channel. Because of the existing steep slopes,
providing a bankfull bench will grant storm flows the opportunity to expand reducing the
shear stress on the terrace slopes. The terrace slopes will be laid back to a 2H:1 V minimum
slope. Due to the high velocities and steep slopes a rock toe (Class II rip-rap) on the bankfull
channel and terrace toe is proposed to further stabilize the channel. The bankfull bench will
be covered with erosion control blanket and planted with riparian grasses. The terrace slopes
will also be covered with an erosion control blanket, a riparian seed mix, and will be planted
with woody vegetation. Plants will also be planted in the buffer, at the top of the terrace
within zone 1, to establish a woody stream buffer. To ensure the vertical stability of the
channel two constructed riffles are proposed. They are located within the channel on the plan
Page 7 of 14
just upstream of the existing headwall and just downstream of the 18" drainage pipe. It is
anticipated that a small track hoe, dump truck, rubber tire loader, and small
compaction/vibration unit will be used to construct this project. Since the channel is
normally dry except for storm flow, it is anticipated that no pump around will be required
during construction.
11. Explain the purpose of the proposed work: The purpose of the project is to stabilize
currently severely eroding stream banks to prevent further damage and sediment input into
the stream. Other goals of the project are to improve the channel eroded dimensions, and
provide for a better vegetative buffer on the stream and terrace banks.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules.
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.
VL 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

Pond to be created in (check all that apply): ? uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): N/A
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):
Size of watershed draining to pond: Expected pond surface area:
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.
The stream repair is required to stop the progressing stream bank erosion in this area If no
improvements are made the stream will continue to head cut and further stream bank erosion will
occur. The project is needed to repair and stabilize a channel that has been eroded to dimensions
beyond stable conditions. The repair impact to the channel will create a stable bankfull channel
bankfull bench, and sloped 2H: IV terrace banks The use of rock materials is required in this
repair due to the steep slopes and resulting high velocities for stormwater flows The use of
Page 10 of 14
rock materials will be minimized to the toe of the slope to bankfull. toe of terrace banks, and for
the creation of riffles in the new channel.
VHL 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
http://h2o.enr.state.nc.us/ncwetlands/strmgide.htH.
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.
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
Page 11 of 14
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
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet): N/A
Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):
IX. Environmental Documentation (required by DWQ)
Does the project involve an expenditure of public (federal/state) funds or the use of public
(federal/state) land?
Yes ? No
If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No
If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEPA or SEPA final approval letter.
Yes ? No ?
X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify Neuse River )?
Yes ® No ? If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.
Page 12 of 14
Zone* Impact
(square feet) Multiplier Required
Mitigation
1 8,000 3
2 2,000 1.5
Total
* Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
The buffer impacts will only be temporary during the construction phase of the project adjacent
to the stream Currently the buffers in zone one have no vegetation or only_g_rass. Zone 1 will be
enhanced with the planting of riparian seed mix and woody vegetation on the top of the bankfull
bench, terrace slopes and terrace top with this repair pWiect Zone two which is currently
grassed will be returned to its original condition if impacted by construction equipment.
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
