Subject: Proposed repair of failed culvert wing wall and streambank of Perry Creek
adjacent to the I-540 off-ramp at US 1 (north) in Wake County. WBS
Element No. 34365.3.35
The North Carolina Department of Transportation (NCDOT) proposes to repair the
existing situation at the damaged culvert wing wall and streambank of relocated Perry
Creek adjacent to the I-540 off-ramp at US 1 (north). The culvert and relocated Perry
Creek are part of R-2000EB, a section of the Northern Wake Expressway that was
constructed in 1999-2003. The NCDENR-DWQ issued a 401 WQC for this project on
January 14, 1999 (WQC Project No. 960319). The culvert outlet wing wall and
downstream streambank suffered massive damage during Tropical Storm Alberto on June
15, 2006. The footing of the northern wing wall became displaced resulting in the
cracking of the 25-foot long wing wall near the location of a 24 inch drainage structure.
The damage to the wing wall caused extensive erosion behind the structure, extending all
the way up to natural ground adjacent to the off-ramp. The erosion behind the wing wall
was temporarily stabilized with rip rap in September and October 2006.
The attached recent photographs depict the existing situation:
-Photograph 1 depicts the cracked wing wall and attempts to stabilize the area. Note that
the wing wall is approximately 25 feet long.
-Photograph 2 depicts the damage to the wing wall and the downstream streambank. The
size of the stream and boulders are rather deceptive. The boulders are up to 4 feet wide
and the stream (including vegetation in the bed) is up to 20 feet wide.
-Photograph 3 depicts an isolated scour located on the southwest streambank.
The NCDOT proposes to repair the existing situation by conducting the following
activities at the site (see Plan Sheet 4):
-Removal of failed wing wall and footing.
-Install approximately 65 linear feet of gabion wall on the failing northern streambank
downstream of the culvert headwall. The gabion wall will extend below the surface
water (See Plan Sheets S-1 and S-2). The gabion wall will be placed within the footprint
of the existing damaged wing wall or existing boulder streambank protection installed

during the construction of relocated Perry Creek and will not result in additional
impacts to surface waters.
-Remove damaged 24 inch drainage structure and replace/relocate with a 30 inch
drainage structure that outlets within the gabion wall at stream grade.
-Install additional Class II rip rap on northeast streambank above existing boulders. This
rip rap will be placed between and above the existing boulders installed along the
streambank in this area and will not result in additional impacts to surface waters.
-Install up to 47 linear feet of Class II rip rap in isolated scour located on southwest
streambank. This rip rap will extend below the OHW and will result in new impacts to
surface waters.
Impacts to Waters of the United States
The removal of the existing failed structure and installation of the gabion wall and Class
II rip rap will result in impacts to the unnamed tributary to Perry Creek (NCDENR-
DWQ Index No. 27-25-(2), Best Usage Classification C, NSW and HUC 03020201) in
the Neuse River Basin.
Site 1
The placement of up to 471inear feet of Class II rip rap in the isolated scour on the southwest
streambank will extend below the OHW and will result in new impacts to surface waters.
Site 2
Bank stabilizaton with the gabion wall and installation of additional Class II rip rap on the
northeast streambank will not result in additional impacts to surface waters. The gabion wall
and rip rap are located within the footprint of the damaged wing wall and streambank
boulders installed during construction of relocated Perry Creek.
Waters of the U.S. Mitigation
Avoidance:
Permanent impacts to the relocated Perry Creek cannot be avoided. The existing wing
wall and downstream streambank suffered massive damage during Tropical Storm
Alberto on June 15, 2006. The NCDOT geotechnical unit has determined that the a
gabion wall will provide stabilization to the northeast streambank. Class II rip rap is
required on the southwest streambank to provide long-term stability.
Minimization:
The proposed gabion wall and Class II rip rap stabilization has been minimized as much
as possible while providing the required long-term stability.
Compensatory Miti ation:
Compensatory mitigation is not proposed for this activity.
Riparian Buffer
Construction at this site involves the road crossing of a stream that is subject to the
Neuse River Riparian Buffer Rules. Perry Creek is depicted on the most recent version
of the Wake Forest (USGS 1967, 2987) topographic quadrangle (Figure 1) and Soil
Survey of Wake County (USDA, 1970) (Figure 2). Note that the riparian buffer
associated with the construction of this project was~reviously disturbed by construction
of R-2000EB in 1999-2003. The site is now dominated by herbaceous vegetation

3
dominated by Korean lespedeza and various weeds and grasses. Construction impacts
are as follows:
Site 1
Construction at Buffer Site 1 site will result in impacts of 1,348 square feet in Zone 1 and
1,268 square feet in Zone 2 (totaling 471inear feet of riparian buffer impacts). Based on
the impacts to the riparian buffer at this site, this crossing is ALLOWABLE. Temporary
erosion control measures will be installed as required within the permitted buffer
footprint. The Department proposes to stabilize the riparian buffer with standard seed
mix. No reforestation is proposed at the site.
Site 2
Construction at Buffer Site 2 will result in impacts of 4,370 square feet in Zone 1 and
3,911 square feet in Zone 2 (totaling 1401inear feet of riparian buffer impacts). Based on
the impacts to the riparian buffer at this site, this crossing is ALLOWABLE. Temporary
erosion control measures will be installed as required within the permitted buffer
footprint. The Department proposes to stabilize the riparian buffer with standard seed
mix. No reforestation is proposed at the site.
Summary
Application is hereby made for a NCDENR-DWQ Section 401 Water Quality
Certification (WQC) No. 3626 and riparian buffer authorization. An automated payment
procedure has been implemented between the NCDOT and NCDENR-DWQ. This
procedure will enable the Department to apply for the 401 WQC without submitting a
check for this permit application. This procedure will provide payment to the NCDENR-
DWQ by charging the permit application fee directly to the appropriate NCDOT WBS
Element No. 34365.3.35. Apre-construction notification, photographs and plan sheets
are attached with this request. If you have any questions or need additional information,
please contact Mr. Chris Murray at [phone].

local stormwater requirement, etc.): N/A
Current land use in the vicinity of the pond: N/A
Size of watershed draining to pond: N/A Expected pond surface area: N/A
VIII. 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.
Avoidance:
Permanent impacts to the relocated Perry Creek cannot be avoided. The existing wing wall and
downstream streambank suffered massive damage during Tropical Storm Alberto on June 15,
2006. The NCDOT geotechnical unit has determined that the a gabion wall and Class II rip rap
will provide stabilization to the north and northeast streambank. Class II rip rap is required on
the southwest streambank to provide long-term stability.
Minimization:
The proposed gabion wall and Class II rip rap stabilization has been minimized as much as
possible while providing the required long-term stability.

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 January 15, 2002, 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 maybe 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.

NORTH CAROLINA 401 WATER QUALITY CERTIFICATION
THIS CERTIFICATION is issued in conformity with the requirements of Section 401
Public Laws 92-500 and 95-217 of the United States and subject to the North Carolina Division
of Water Quality (DWQ) Regulations in 15 NCAC 2H, Section .0500 to NC DOT resulting in
48.43 acres of wetland and 12.18 acres of stream impact in Durham and Wake Counties pursuant
to a revised application filed on the 29m day of March of 1996, the 12m day of August of 1996, the
31"day of October of 1996, the 6°i day of May of 1997, the 9m day of February of 1998 the 31"
day of March of 1998, the 8~ day of May of 1998, and the 18m day of November of 1998 to
construct the Northern Wake Expressway Sections R-2000 CA, D, CB, EA, EB, F, G and A.
The application provides adequate assurance that the discharge of fill material into the
waters of Crossing Kit Creek, Lower Bartons Creek, Perry Creek, Neuse River, Beaverdam
Creek and their tributaries in conjunction with the proposed development will not result in a
violation of applicable Water Quality Standards and discharge guidelines. Therefore, the State of
North Carolina certifies that this activity will not violate the applicable portions of Sections 301,
302, 303, 306, 307 of PL 92-500 and PL 95-217 if conducted in accordance with the application
and conditions hereinafter set forth.
This approval is only valid for the purpose and design that you submitted in your
application, as described in the Public Notice. If you change your project, you must notify us
and send us a new application for a new certification. If the property is sold, the new owner must
be given a copy of the Certification and approval letter and is thereby responsible for complying
with all conditions. If total wetland fills for this project (now or in the future) exceed one acre,
compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h) (6) and (7).
For this approval to be valid, you must follow the conditions listed below. In addition, you
should get any other federal, state or local permits before you go ahead with your project
including (but not limited to) Sediment and Erosion control, Coastal Stormwater, Non-discharge
and Water Supply watershed regulations. '
Condition(s) of Certification:
1. That the activity be conducted in such manner as to prevent significant increase
in turbidity outside the are of construction or construction related discharge (SO NTU's
in streams and rivers not designated as trout waters by DWQ; 25 NTU's in all saltwater
classes, and all lakes and reservoirs; 10 NTU's in trout waters).
2. Should waste or borrow sites be located in wetlands, compensatory mitigation
will be required since it is a direct impact from construction activities.
3. Land clearing in wetlands shall conform to Method II (no clearing beyond tce of slope).
4. Compensatory wetland and stream mitigation shall be in accordance with the U.S. Army
Corps of Engineers requirements. DWQ shall be copied on the approved ratio, location,
size and method of debit (restoration, enhancement, creation and preservation). In your
modification request of May 8, 1998, you requested cone-year extension on the
implementation schedule for the Dutchman's Creek mitigation site in Wake County, in
order to address concerns expressed by the Audubon Soaety and adjacent property
owners. You are hereby notified that implementation of work at the Dutchman's Creek
site may be delayed until May 1999, and that work on sections R-2000CB and D of the
Northern Wake Expressway may proceed as planned. Your future negotiations with
regard to the Dutchman's Creek property may involve substantial changes to the

r
construction specifications for that site, and will likely result in a loss of your planned
stream and wetland restoration components. In accordance with 15A NCAC
2H.0506(h)(1) and (6), 1:1 restoration or creation of wetlands and streams will still be
required at another location if this condition cannot be satisfied at Dutchman's Creek.
DOT should also note that, in accordance with our rules, the Wetland Restoration
Program will be available to use for wetland mitigation for this project.
5. All channel relocations will be designed and constructed according to DOT's stream
relocation/channelization guidelines to the maximum extent practicable. To achieve this
end, DOT shall coordinate the stream relocation design, construction and receive
approval from the staff of the WRC.
6. The applications referenced above contain final and preliminary designs. DOT shall
submit requests for permit modifications to the DWQ after the preliminary designs have
been finalized.
7. The bridging at the Neuse River shall be extended to Station 395 and 60 to reduce
significant wetland impacts (Site 6). To the extent practicable, DOT shall not install the
bridge bents in the river. Weep holes shall not be installed in the bridge. H this is not
completely possible, weep holes shall not be installed duectiy over water.
8. This project occurs within the Neuse River Basin. In accordance with 15A NCAC 2B
.0233, you aze required to maintain a 50 foot vegetated buffer to each side (100 feet
total) of relocated intermittent and perennial streams, to the maximum extent practical.
The project will include 3,5601inear feet of perennial streams. You should attempt to
maintain vegetated buffers along these systems, along with any intermittent streams not
included in the application. Also, you are required to ensure that stormwater runoff will
not be directed into surface waters prior to some form of treatment (i.e. diversion
through vegetated swales). Please note, this means that weep holes will not be
permitted on bridge decks.
9. Reference NCDOT's modification request of November 10, 1998 (received November
18, 1998), which provided final design impacts for R2000EA and EB, including an
interchange at the North-South Connector Road. The 401 Water Quality Certification is
hereby modified to allow construction of this interchange and to include the final design
plans for R2000EA/EB. This will include 7970 lineaz feet of perennial stream impacts,
including 2857 linear feet of onsite stream relocation, and 51131ineaz feet of perennial
stream loss, along with an additional 1.96 acres of wetland impacts. We understand that
DOT has chosen to mitigate the stream impacts through 1) a contribution to the Wetland
Restoration Program for 51131ineaz feet of restoration and 2) the Wake County Stream
Mitigation Plan. DOT has chosen to mitigate the additional 1.96 acres of wetland
impacts at DOT's New Light Creek and Phillips Mitigation Sites. Mitigation ratios shall
be in accordance with requirements set by the U.S. Army Corps of Engineers; however,
since only 0.99 acre of restoration area is available at these sites, 0.97 acre shall be
mitigation through a contribution to the Wetland Restoration Program for 1.0 acre of
wetland restoration. In accordance with 15A NCAC 28.0500, this contribution will
satisfy our compensatory mitigation requirements under 15A NCAC 2H.0506(h).
According to 15A NCAC 2H.0506(h), S 113 linear feet of stream restoration will be
required for 5113 linear feet of stream Impacts, and 1.0 acre of wetland restoration will
be required for 0.97 acre of wetland impacts. Until the Wetland Restoration Program
receives and clears your check (made payable to DENR -Wetland Restoration
Program), wetland or stream fill shall not occur. Mr. Ron Ferrell should be contacted at
\\

a f
K
919-733-5083 ext. 358 if you have any questions concerning the Wetland Restoration
Program. You have two months from the date of this Certification to make this
payment. For accounting purposes, this Certification authorizes the fill in 79701inear
feet of streams and an additional 1.96 acres of wetlands in the Neuse River and
Subbasin and 2857 feet of onsite stream relocation and offsite wetland mitigation by
DOT combined with S 113 linear feet of stream restoration and 1.0 acre of wetland
restoration through WRP are required. Please be aware that the Wetland Restoration
Program rules require rounding of stream impacts to the nearest foot and wetland
impacts to the nearest one-quarter acre (15A 2R .0503(b)).
Violations of any condition herein set forth shall result in revocation of this Certification
and may result in criminal and/or civil penalties. This Certification shall become null and void
unless the above conditions are made conditions of the Federal 404 and/or coastal Area
Management Act Permit. This Certification shall expire upon expiration of the 404 or CAMA
Permit.
If this Certification is unacceptable to you have the right to an adjudicatory hearing upon
written request within sixty (60) days following receipt of this Certification. This request must
be in the form of a written petition conforming to Chapter 150B of the North Carolina General
Statutes and filed with the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C.
27611-7447. If modifications are made to an original Certification, you have the right to an
adjudicatory hearing on the modifications upon written request within sixty (60) days following
receipt of the Certification. Unless such demands are made, this Certification shall be final and
binding.
