6508 Falls of the Neuse Road, Suite 120
Raleigh, NC 27609
Attention: Mr. Eric Alsmeyer, NCDOT Coordinator
Subject: Proposed extension of a structure conveying an unnamed tributary to
Mango Creek on SR 2516 (Hodge Road) in Wake County.
The North Carolina Department of Transportation (NCDOT) proposes to extend the
structure and widen the narrow and unsafe shoulder above the inlet and repair the
shoulder above the outlet (Figures 1 - 3).
Impacts to Waters of the United States
The project crosses a perennial stream, an unnamed tributary to Mango Creek,
[NCDENR-DWQ Index No. 27-32, Best Usage Classification C NSW; HUC 03020201]
(Figure 3) in the Neuse River Basin. The existing structure that conveys the creek is a
concrete pipe with old headwalls. Please note that the roadway shoulder above the inlet is
narrow and unsafe. Also the shoulder section and fill slope above the outlet needs
repairing and armoring with rip rap (Photographs 1 and 2). In order to widen the
associated roadway shoulder, two joints will be added to the inlet of the existing
structure. Once the joints are set, the associated roadway shoulder will be rebuilt and the
areas surrounding both pipe ends will be stabilized using riprap for armoring. The
NCDOT proposes to temporarily dewater the work zone during the construction. This
will involve the temporary placement of sandbags and/or sheet piling in the creek
upstream and downstream of construction. Once the stream has been dewatered, the pipe
will be extended. Permanent impacts at the site involve a total of 8 feet of surface water
fill and 20 feet of rip rap placed along the streambanks to protect the pipe ends.
Concurrent temporary impacts to the stream from this activity will result in the dewatering of
28 linear feet of stream. The work zone will be dewatered for approximately 3 days. All
materials used for dewatering will be removed after construction.
Please ~zote that ~~etla~2d areas surround this crross line. However the n~o~°k to extend the
structure will result in surface water fill oily. The.fill-slopes will not be extended beyond
the existing toe of fill other than at the stream channel.

Riparian Buffer
Construction at this site involves a road crossing of a stream that is subject to
the Neuse River Riparian Buffer Rules. The UT to Mango Creek at Site 1 is depicted on
the most recent version of the Raleigh East (USGS 1968/1987) topographic quadrangle
- (Figure 1) as well as the Soil Survey of Wake County (USDA-SCS 1970) (Figure 2).
Construction impacts at this site total 1,885 ft' in Zone 1 and 1,244 ft` in Zone 2 (totaling
28 linear feet of riparian buffer impacts). Based on the impacts to the riparian buffer at
this site, this crossing is EXEMPT.
Waters of the U.S. Mitigation
Avoidance: All wetlands and surface waters not affected by the project will be protected
from unnecessary encroachment. No staging of construction equipment or storage of
construction supplies will be allowed in wetlands or near surface waters.
Minimization: The side slopes have been steepened to the extent possible at jurisdictional
sites. Strict enforcement of sedimentation and erosion control Best Management Practices
for the protection of wetlands and surface waters will be enforced during project
construction. Continued coordination will occur with maintenance forces and the
Environmental Officer during construction to minimize impacts to these sites.
Compensatory Mitigation: All compensatory mitigation requirements will be left to the
discretion of the regulatory review agencies.
Protected Species
Plants and animals with federal classifications of Endangered, Threatened, Proposed
Endangered, and Proposed Threatened are protected under provisions of Section 7 and
Section 9 of the ESA. There are four federally protected species listed for Wake County.
They include bald eagle (Haliaeetus leucocephah~~s), red-cockaded woodpecker (Picoides
borealis), dwarf wedgemussel (Alasmidonta heterdon), and Michaux's sumac (Rhos
~yuchcarxii). The project site is not adjacent to nor is it surrounded by open water suitable of
supporting foraging habitat for the bald eagle. The open residential and agricultural land
surrounding this roadway do not offer suitable forging or nesting habitat for red-cockaded
woodpecker. Roadway shoulders along this section of SR 2516 are heavily maintained,
eliminating the possibility for Michaux's sumac to exist in this area. Additionally, this small
UT to Mango Creek is within the headwaters of its system and does not provide. suitable
habitat for dwarf wedgemussel. Based on lack of suitable habitat observed during the
02/16/07 site visit and a review of the Natural Heritage Database last updated Fall 2006,
biological conclusions of No Effect have been rendered for each of these species.
Summary
The NCDOT proposes to extend the existing structure on the outlet end and rebuild the
roadway shoulders above both ends. Rip rap armoring will be added to stabilize both
ends of the pipe. Permanent impacts at the site associated with this work involve a total
of 8 feet of surface water fill and 20 feet of rip rap placed along the streambank to protect
the pipe ends. The work zone will be dewatered for approximately 3 days. Concurrent
temporary impacts to the stream from this activity will result in the dewatering of 28 linear
feet of stream. The materials used for dewatering will be removed after construction.
Riparian buffer impacts at Site 1 associated with this maintenance activity total 1,885 ft`

3
in Zone 1 and 1,244 ft' in Zone 2 (totaling 28 linear feet of riparian buffer impacts).
Based on the impacts to the riparian buffer at this site, this crossing is EXEMPT.
Please note that x~etland areas stcrrotcnd this cross line. Howei~er the work to extend the
structure will result in surface water, fill only. The fill slopes will not be extended beyond
the existing toe of fill other than at the stream channel.
Application is hereby made for a Department of the Army Section 404 Nationwide
Permit (NWP) 3 and NWP 33. Additionally, this application provides notification to the
NCDWQ as Section 401 Water Quality Certification (WQC) No. 3494 and No. 3366 will
be utilized for construction of this project. The NCDOT will comply with all applicable
NWP and WQC conditions. Apre-construction notification is attached with this request.

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. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should 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.
Provide a written description of the proposed impacts: A total of 8ft of surface water fill will
result from adding, two joints of pipe to the inlet end. Additionally 10 tt of rip rap armoring will
be added to both the inlet and the outlet of the structure. Also 28 tt of concurrent dewatering is
proposed.

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. All wetlands and surface
waters not affected by construction will be protected from unnecessary encroachment during
construction. Strict enforcement of Best Management Practices for the protection of wetlands
and surface waters will be enforced during construction. Only the smallest amount of fill
necessary to complete the project will be placed in waters of the United States.
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.
USAGE - 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
Page 5 of 8

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 USAGE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP 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.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,
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.
All compensatory mitigation requirements will be left to the discretion of the regulatory
review agencies.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five 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): N/A
Amount of Non-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A
IX. Environmental Documentation (required by DWQ)
1. Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federal/state) land? Yes ® No ^
2. 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 aNEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ^ No

3. 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 ^
~C. 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 froth the DWQ
Regional Office tray be included as appropriate. Photographs tray also be included at the
applicant's discretion.
1. Will the project impact protected riparian buffers identified within I SA NCAC 2B .0233
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify )? Yes ® No ^
2. If "yes", 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.
Site 1
Zone* Impact
(square feet) Multiplier Required
Mitigation
1 1,885 3 (2 for Catawba) N/A
2 1,244 1.5 N/A
Total 3,129 ~ N/A
* Zonc I extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an
additional 20 feet ti•om the edge of Zone 1.
3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration /Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or .0244, or .0260. N/A
XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
stonnwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level. No additional impervious surface is proposed
with this maintenance proiect. Erosion and sediment control devices at these sites are comprised
of temporary dewaterin . ag nd ripp rap armoring the structure ends.

XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
- wastewater generated from the proposed project, or available capacity of the subject facility.
This maintenance project will not generate wastewater.
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ^ No
Is this an after-the-fact permit application? Yes ^ No
XIV. Cumulative Impacts (required by DWQ)
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ^ No
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
http:!/h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description:
This maintenance project will not result in additional development.
XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for. these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
