Subject: Modification of Nationwide Permit No. 27 for the restoration of an unnamed
tributary to Swift Creek.
Dear Sirs:
The Town of Cary requests your review of the following permit modification for the additional
restoration of an unnamed tributary to the unnamed tributary to Swift Creek. This request is linked
to the NWP 14 and NWP 27 permits already issued for the widening of SW Maynard Road and
the stream restoration: USACE Permit ID 200320636/20040872/200420873 issued April 16, 2004
and NCDWQ Project # 04-0313. The Town requested and was granted an extension of these
permits in February 2006.
These permits involve the widening of the existing two lane SW Maynard Road from West
Chatham Street (SR 1011) to Kildaire Farm Road (SR 1300). The proposed 1.24 mile long
project will provide a five-lane curb and gutter, 70-foot wide roadway that will connect the existing
multilane sections of Maynard Road. The road widening will cross an unnamed tributary to Swift
Creek in the Neuse River basin. To accommodate the road widening the existing two 72-inch
concrete pipes (80 feet in length) carrying the stream under Maynard Road will be replaced with a
double concrete box culvert (9 feet by 8 feet per barrel) 146 feet long.
Stantec
March 7, 2007
Page 2 of 3
To mitigate for the additional impacts to the stream and also to provide mitigation credits for future
use, the Town also proposed to restore 1767 linear feet of the unnamed tributary above the SW
Maynard Road crossing. Using Rosgen natural channel design techniques the existing degraded
G4 stream channel will be restored (Priority 2) to a C4 stream type with new floodplain at a slightly
lower elevation. Where practical, the new design follows near the old channel to minimize
impacts to the existing riparian buffer.
Details of the road crossing and restoration of the main stream channel can be found in the
original permit application package submitted in March of 2004.
Project Update: In January 2005, The Town of Cary received a grant to design and construct
stormwater wetland BMPs on Town property adjacent to the unnamed tributary to address
stormwater impacts to the watershed, reduce nitrogen, and improve water quality. To
accommodate and provide the best location for the BMPs, the pattern of the proposed restoration
of the main channel has been adjusted slightly. The attached plan sheets show the updated
design.
The "offline" stormwater BMPs will improve upon and replace the six "pocket wetlands" identified
in the original permit application. They are designed to treat stormwater coming from the adjacent
neighborhood as well as some bankfull stream events. BMPs were also designed along the
tributary above the main restoration reach. As part of the total BMP / restoration project the Town
also decided to restore the tributary. The tributary as with the main channel, has been degraded
and destabilized by excess stormwater. When complete, The Town will have maximized the
restoration and stormwater treatment potential within its property boundaries above Maynard
Road. The restored stream and BMP system should greatly improve the water quality and aquatic
habitat in this tributary to Swift Creek which is listed as a 303d stream.
The Town chose to bid the road widening, stream restoration, and BMP construction as one
project to have a single contractor responsible for the work. This required some time to merge the
bid documents for the road construction and stream restoration. Requirements were added to
ensure that the subcontractor for the stream restoration was experienced at that work. The bid
process took place in the fall of 2006. The contract for the road construction and stream
restoration was awarded in February 2007. The start of construction is anticipated in the Spring
2007 with completion of the stream restoration and BMP construction in the summer of 2007.
Tributary
The tributary to the main channel is a small perennial stream that has become degraded from
large increases in stormwater flows. The watershed of the tributary encompasses Chatham
Street and residential development above it. The channel is relatively straight and incised. The
increased volume of stormwater has caused the stream channel to downcut and has left vertical
eroding banks. The existing channel is 416 feet long. The existing floodplain forest and riparian
buffers have remained intact.
The proposed restoration will move the channel slightly to the south and bring the channel
elevation up as much as possible within the constraints of the culvert elevation at Chatham Street
and the downcut elevation of the main channel. The restoration will be a combination of Priority 1
and 2. Sinuosity will be increased in the restored channel, cross vanes and bank protection will
help stabilize the channel and add aquatic habitat. The restored channel length is 453 linear feet.
The stormwater wetlands will be constructed in the new floodplain to improve water quality.

The tributary design is shown on sheet "Stream 4" of the attached design plans. The planting plan
for the tributary is shown on sheet "Stream 6". The typical cross sections are shown on sheet
"Stream 2A". Also, attached is the morphological table for the proposed restoration reaches and
reference reaches.
Request is made modify the existing Nationwide Permit No. 27, and the corresponding 401 Water
Quality Certification and riparian buffer approval for the above-mentioned activities. In compliance
with Section 143-215.3D(e) of the NCAC the Stantec will provide a $475.00 check as payment for
processing the Section 401 WQC modification. Two copies of this request, including attachments
(one full set of plans and one partial set), are being provided to the USACE Raleigh Regulatory
Field Office. Seven copies of the request and attachments (one full set of plans and six partial
sets), are being provided to the North Carolina Division of Water Quality Wetlands / 401 Unit, for
their review.
Thank you for your assistance with this project. If you have any questions or need any additional
information about this permit application, please contact Pete Colwell at 919-851-7369.

MAXAMIZE WATER QUALITY BENFITS AND MINIMIZE IMPACTS TO THE EXISTING
RIPARIAN BUFFERS
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
Page 5 of 8
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
hllp://h2o.enr.state.nc.us/ncwetlands/strmizide.httnl.
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,
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.
NO MITIGATION IS PROPOSED FOR THE RESTORATION OF THE TRIBUTARY TO
THE MAIN CHANNEL. THE 0.01 ACRE WETLAND DEPRESSION WILL BE
INCORPORATED INTO A POCKET WETLAND. OTHER IMPACTS DESCIRBED IN
THE PREVIOUS PERMITS WILL BE MITIGATED FOR BY THE RESTORATION OF
THE MAIN TRIBUTARY. RIPARIAN BUFFERS ALONG THE STREAM WILL BE
REPLACED AND ENHANCED BY THE REMOVAL OF EXOTIC SPECIES. SEE
ATTACHED RESTORATION PLAN.

Page 2 of 3
To mitigate for the additional impacts to the stream and also to provide mitigation credits for future
use, the Town also proposed to restore 1767 linear feet of the unnamed tributary above the SW
Maynard Road crossing. Using Rosgen natural channel design techniques the existing degraded
G4 stream channel will be restored (Priority 2) to a C4 stream type with new floodplain at a slightly
lower elevation. Where practical, the new design follows near the old channel to minimize
impacts to the existing riparian buffer.
Details of the road crossing and restoration of the main stream channel can be found in the
original permit application package submitted in March of 2004.
Project Update: In January 2005, The Town of Cary received a grant to design and construct
stormwater wetland BMPs on Town property adjacent to the unnamed tributary to address
stormwater impacts to the watershed, reduce nitrogen, and improve water quality. To
accommodate and provide the best location for the BMPs, the pattern of the proposed restoration
of the main channel has been adjusted slightly. The attached plan sheets show the updated
design.
The "offline" stormwater BMPs will improve upon and replace the six "pocket wetlands" identified
in the original permit application. They are designed to treat stormwater coming from the adjacent
neighborhood as well as some bankfull stream events. BMPs were also designed along the
tributary above the main restoration reach. As part of the total BMP / restoration project the Town
also decided to restore the tributary. The tributary as with the main channel, has been degraded
and destabilized by excess stormwater. When complete, The Town will have maximized the
restoration and stormwater treatment potential within its property boundaries above Maynard
Road. The restored stream and BMP system should greatly improve the water quality and aquatic
habitat in this tributary to Swift Creek which is listed as a 303d stream.
The Town chose to bid the road widening, stream restoration, and BMP construction as one
project to have a single contractor responsible for the work. This required some time to merge the
bid documents for the road construction and stream restoration. Requirements were added to
ensure that the subcontractor for the stream restoration was experienced at that work. The bid
process took place in the fall of 2006. The contract for the road construction and stream
restoration was awarded in February 2007. The start of construction is anticipated in the Spring
2007 with completion of the stream restoration and BMP construction in the summer of 2007.
Tributary
The tributary to the main channel is a small perennial stream that has become degraded from
large increases in stormwater flows. The watershed of the tributary encompasses Chatham
Street and residential development above it. The channel is relatively straight and incised. The
increased volume of stormwater has caused the stream channel to downcut and has left vertical
eroding banks. The existing channel is 416 feet long. The existing floodplain forest and riparian
buffers have remained intact.
The proposed restoration will move the channel slightly to the south and bring the channel
elevation up as much as possible within the constraints of the culvert elevation at Chatham Street
and the downcut elevation of the main channel. The restoration will be a combination of Priority 1
and 2. Sinuosity will be increased in the restored channel, cross vanes and bank protection will
help stabilize the channel and add aquatic habitat. The restored channel length is 453 linear feet.
The stormwater wetlands will be constructed in the new floodplain to improve water quality.

The tributary design is shown on sheet "Stream 4" of the attached design plans. The planting plan
for the tributary is shown on sheet "Stream 6". The typical cross sections are shown on sheet
"Stream 2A". Also, attached is the morphological table for the proposed restoration reaches and
reference reaches.
Request is made modify the existing Nationwide Permit No. 27, and the corresponding 401 Water
Quality Certification and riparian buffer approval for the above-mentioned activities. In compliance
with Section 143-215.3D(e) of the NCAC the Stantec will provide a $475.00 check as payment for
processing the Section 401 WQC modification. Two copies of this request, including attachments
(one full set of plans and one partial set), are being provided to the USACE Raleigh Regulatory
Field Office. Seven copies of the request and attachments (one full set of plans and six partial
sets), are being provided to the North Carolina Division of Water Quality Wetlands / 401 Unit, for
their review.
Thank you for your assistance with this project. If you have any questions or need any additional
information about this permit application, please contact Pete Colwell at 919-851-7369.
