SUBJECT: Emergency pipe replacements, SR 1333, Lincoln County
Dear Mr. Hennessy:
The North Carolina Department of Transportation proposes to replace two pipes which collapsed as a
result of the storm events of 10/7/05 on SR 1333, Walker Branch Road in Lincoln County. The pipe
replacements are considered emergency projects and construction is to commence immediately. The
collapsed pipe at site 1 is a 50-foot long, 48" CMP that will be replaced with a 50-foot, 96" CMP. A
large scourhole ( 15ft wide x 20 ft long) has formed at the outlet of the existing perched pipe.
Additionally, the adjacent property owner has constructed a concrete ditch that discharges directly into
the stream at the scourhole and the property owner has also placed large pieces of concrete along the
downstream meander bend streambank. Due to the existing conditions, a 10-15 ft rock bench will be
constructed along the right bank at the outlet that will tie into the private concrete bank stabilization. The
construction of the rock bench will narrow the stream closer to the "normal" stream dimensions and the
rock will also act as energy dissipation for the stormwater discharge from the concrete ditch. The
proposed pipe burial will be based upon the streambed elevation directly downstream of the scourhole. To
reconnect the upstream and downstream elevation, the new pipe will be on a -7% slope; therefore, we
propose to embed rock into the existing scourhole to provide additional energy dissipation. At site 2, a
30", 70-ft pipe is to be replaced with an 84", 70-ft pipe. Based upon thalweg elevations, the proposed
pipe will be placed on a 5.5% slope; therefore, riprap will also be embedded into an existing scourhole at
this location to provide energy dissipation. A total of 10 feet of riprap will be utilized on the embankment
at the inlet and outlet of both pipes for structure stabilization. The scope of the work will result in a total
of 30 feet of permanent riprap/rock to Walker Creek and an unnamed tributary to Walker Creek, which is
classified as a WS IV watershed by the Division of Waxer Quality.
SR 1333 is not considered a rural or urban arterial, nor is the project located within %2 mile of a critical
watershed area. Hazardous spill basins are not required. Enclosed is the NCDOT hazardous spill basin
checklist.

Emergency replacement of a two collapsing _pipes- 1) 48". 50-ft pipe to be replaced
with %% 50-ft give and 2) 30". 70-ft give to be replaced with 84". 70-ft nine. At
the outlet at site 1 a large scour has formed and the stream width is twice the "normal"
stream width. Additionally, the adjacent property owner has constructed a concrete
ditch that discharges directly into the stream and has placed large pieces of concrete
along the streambank in the downstream meander bend. Due to the existing
conditions, a 10-15 ft rock bench will be constructed along the bank at the outlet in an
effort to restore the stream to normal dimensions; the rock will also act as enerav
dissipation for the stormwater discharge from the concrete ditch. The existing tine is
perched: therefore, it will be necessary to place the new pipe on -7% slope to
reconnect the upstream and downstream. We propose to embed rock into the existing
scourhole to provide additional energy dissipation. At site 2 the proposed pipe will be
placed on a 5.5% slope; therefore, riprap will also be embedded into the existing
scourhole at this, location to provide energy dissipation. A total of 10 feet of riprap
will be utilized on the embankment at the inlet and outlet of both pipes for structure
stabilization. Work will be done using a trackhoe.

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 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 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.
MITIGATION NOT ANTICIPATED
2. Mitigation may also be made by payment into the North Carolina Wetlands
Restoration Program (NCWRP). Please note it is the applicant's responsibility to
contact the NCWRP at [phone] to determine availability and to request
written approval of mitigation prior to submittal of a PCN. For additional.

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.
Will the project impact protected riparian buffers identified within 15A NCAC 2B
.0233 (Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman
Rules and Water Supply Buffer Requirements), or other (please identify-)?
Yes ? No ® If you answered "yes", provide the following
information:
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 multi liers.

XL Stormwater (required by DWQ)
Describe impervious acreage (both existing and proposed) versus total acreage on the
site. Discuss stormwater controls proposed in order to protect surface waters and
wetlands downstream from the property.
There will be no increase in impervious acreage. Appropriate erosion and
sedimentation control measures will be in place during the pipe replacements.
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.
NA
XM. 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. 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).
NA
