Attention: Mr. Eric Alsmeyer, NCDOT Coordinator 4J ! -!
Subject: Proposed repair of a structure conveying an unnamed tributary to
Moccasin Creek on SR 2309 (Dukes Lake Road) in Wake County.
The North Carolina Department of Transportation (NCDOT) proposes to repair a pipe
conveying an unnamed tributary to Moccasin Creek on SR 2309 (Dukes Lake Road) in
Wake County (Figures 1 - 3).
Impacts to Waters of the United States
The project crosses a perennial stream, UT to Moccasin Creek, [NCDENR-DWQ Index
No. 27-86-2, Best Usage Classification C NSW; HUC 03020203] in the Neuse River
Basin. The existing structure that conveys the creek is reinforced concrete pipe that has
separated joints at the inlet end of the pipe (see Photograph 1). The NCDOT proposes to
reset the separated joints and rebuild the fill slope and shoulder section above the pipe
inlet. Rip rap will be used to armor the pipe end and associated till slope and shoulder
section. No alterations to the outlet end are proposed. During the construction of the
project, the NCDOT proposes to temporarily dewater the work zone for approximately 3
days. This will involve the temporary placement of sandbags in the creek lOlt upstream
of construction. Once the stream has been dewatered, the pipe joints will be reset. The
materials used for dewatering will be removed after construction.
Permanent impacts at the site associated with the repair will involve no surface water fill
but will involve rip rap armoring not to exceed loft along the banks at the pipe inlet.
Temporary impacts will include the dewatering of l Oft of stream.
Please note that ~~etland areas surround this cross line inlet. Hox•ener the work to reset
and the~z armor the separated joints titi•ill not result in impacts to these wetlands as the fill
slopes ~~ill not be extended beyond the existing toe of fill.

for dewatering will be removed after construction. Riparian buffer impacts at this site total
647 ft' in Zone 1 and 395 ft' in Zone 2 (totaling 10 linear feet of riparian buffer impacts).
Based on the impacts to the riparian buffer at this site, this crossing is EXEMPT.
Please note that n~etland a~~eas sasrround this cross line. Ho~•ever the ~•ork to reset and
theft armor the separated joints ~•ill not restalt in impacts to these u~etla~zds as the.fill
slopes n.~ill not be extended bevond the existing toe of fill.
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. If you have any questions or need additional information, please contact Ms.
Heather Montague at [phone].

excavator, backhoe, bulldozer, grader, and crane.
11. Explain the purpose of the proposed work: The first two joints of this pipe have separated
and the over layin fig 11 slope and shoulder section has failed.

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.
N/A
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 additiotlal
space is needed for listing or description, please attach a separate sheet.
Provide a written description of the proposed impacts: Dewaterin~ the stream is necessary to
repair the pipe end Once the pipe joints are reset the NCDOT will repair the existing; roadway
fill slope and shoulder section b~back filling and armoring the~ipe end and stream banks with
rip rap.

6. Isolated Waters
Do any isolated waters exist on the property? ^ Yes ®No
Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USAGE.
N/A
7. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
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.): 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
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. 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
VII[. 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
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,

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 ^
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.

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.
