Attention: Bill Biddlecome
Subject: Request for a NW 3 permit for pipe replacement and stream bank widening on SR 1121 (W J
Duke Service Road) in Northampton County.
This is a request from the North Carolina Department of Transportation for a NW 3 permit for a
pipe replacement and stream bank modification in an unnamed tributary to Urahaw Swamp on SR 1121 (W
J Duke Service Road) in Northampton County. The existing pipe (46'x 42" CMP) will be replaced with the
proposed pipes (2 @ 50'x 73" x 55" CAAP). The current pipe does not allow flood events to convey under
the roadway, which results in backwater flooding of the road shoulder and travel lane. This condition
creates a safety risk, especially during night hours when visibility is low. The additional pipe will increase
the width of the inlet channel. NCDOT is also requesting authorization to widen and stabilize the inlet
stream channel to accommodate flows moving through the two new pipes. The banks will be stabilized
with class Brip-rap. This is illustrated in the provided permit drawings. The proposed work will cause 24
linear feet of stream impacts (4 feet from pipe fill, (0.001 acres) 201ineaz feet from bank excavation (0.003
acres). A site location map, permit drawings, and a PCN form aze included in this letter. If you need any
additional information or have any questions concerning this project please call me at 252-482-7977.
Sincerely,

III. Project Information
Attach a vicinity map clearly showing the location of the property with respect to local
landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no larger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.

9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: woodlands, rural, residential
10. Describe the overall project in detail, including the type of equipment to be used: Replace
the existing_pipe (46' x 42" CMP with the proposed ape (2 (a, 50' x 73" x 55" CAAP) with
alu_ minum headwalls on SR 1121 on their current alignment. The upstream side of the stream
is narrow and constricting flow and therefore causing roadside flooding after rain events.
NCDOT would like to excavate banks of upstream side of stream to allow water to flow
freely into the proposed two new Wipes. Excavated banks will be lined with riprap to prevent
erosion. This will alleviate road floodin during`rain events. The current pipe will be
removed entirely. Proper fill will be used to bring road to existing_hei t. Heavy equipment
used will be an excavator, backhoe, and dump trucks.
11. Explain the purpose of the proposed work: To replace a structurally deficient ape to
enhance natural flow regimes and create safer public travel. Excavate banks of stream on
upstream side of pipes to allow water to move freely.
IV. Prior Project History

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

plans and profiles showing the linear footprint for both the original and relocated streams
must be included. To calculate acreage, multiply length X width, then divide by 43,560. N/A

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 USACE.
8. Pond Creation N/A

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It maybe 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. Pipe replacement is going to
stay on the existing aligmnent and traffic will be detoured around the site by an offsite detour.
This will reduce temporary impacts to the stream by not using an on-site detour and keeping the
road open.
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 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,
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 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
httn://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)
Updated 11/1/2005
Page 10 of 13

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 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.uslwrp/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):
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount ofNon-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):
