Re: Permit Application- Little Sebastian Stream Mitigation Site Mitigation Project, Surry
County (DMS Full Delivery Project)
Dear Mr. Haupt:
Attached for your review is 404/401 permit application package for the subject project. A memo
for the permit application fee is also included in the package. Per agreement between DMS and
DWR, the hard copy of the final mitigation plan is not included in the submittal (However, I did
include a final mitigation plan in this submittal since DMS has extra copies). The electronic
copy of the final mitigation plan along with all other electronic files have been uploaded to NC
DWR's file system. Please feel free to contact me with any questions regarding this plan (919-
707-8319).
Thank you very much for your assistance.
Sincerely

B. Project Information and Prior Project History
3a. Describe the existing conditions on the site and the general land use in the vicinity of
the project at the time of this application:
The Little Sebastian Mitigation Site is a stream mitigation project located within a primarily rural
watershed in Surry County, North Carolina. The Site is located within the Yadkin River Basin
(HUC 03040101, TLW 03040101080020) and in the Middle Mitchell River Watershed, a Targeted
Local Watershed (TLW). The Middle Mitchell River TLW encompasses 25 square miles of
watershed area. Within the 3,261-acre drainage area of the project, the primary land use within
the drainage area consists of approximately 70 percent forest, 25 percent agricultural land, and
less than one percent of the total watershed is impervious surface.
The Project area is comprised of two easement areas along Mill Creek; totaling 25.91 acres and
8,189 existing linear feet of stream. There are seven easement breaks on the project; one
easement break/culvert occurs along JN2-C; one easement break/culvert occurs on JN2-D; one
easement break occurs between MC1-A and MC1-B; one easement break occurs along MC1-B;
one easement break/culvert occurs along JN3-B; one easement/ford crossing breaks occurs on
MC3-B; and one easement break/culvert occurs along BS1-E. The stream channels include Mill
Creek and three unnamed tributaries, split into 18 reaches based on proposed treatment type.
The US Fish and Wildlife Service (USFWS) National Wetland Inventory Map (NWI) does not
depict any potential wetland areas within the Project, but there is freshwater pond mapped
adjacent to Reach JN3.
In general, all or portions of JN2-B, JN2-C, JN2-D, JN3-A, JN3-B, MC1-A, MC1-B, MC1-C, BS1-
A, BS1-B, BS1-C, BS1-D, BS1-E, MC3-B, MC3-C, and MC3-D do not function to their full
potential. Current conditions demonstrate significant habitat degradation as a result of impacts
from agriculture, livestock production, and lack of riparian buffer. Being heavily eroded and
incised, some of the streams do not access their floodplains as frequently as they naturally would
have prior to agricultural operations. In many cases in the lower elevations, the riparian buffer is
in poor condition where much of the riparian buffer is devoid of trees or shrubs and row crops are
present up to the edge of the existing channel. In some of the higher elevation reaches, trees are
present, but understory riparian buffer has been heavily impacted by cattle. Habitat along the
PCN Supplemental Information-Little Sebastian Mitigation Project

much of the restoration reaches is poor in that there is little woody debris or overhanging
vegetation for fish cover or protection for other aquatic species.
3d. Explain the purpose of the proposed project:
The objective for this restoration project is to restore and design natural waterways with the
appropriate cross-sectional dimension and slope that will provide function and meet the
appropriate success criteria for the existing streams. Accomplishing this objective entails the
restoration of natural stream characteristics, such as stable cross sections, planform, and in-
stream habitat. The floodplain areas will be hydrologically reconnected to the channel to provide
natural exchange and storage during flooding events. The design will be based on reference
conditions, USACE guidance (USACE, 2005), and criteria that are developed during this project
to achieve success. Additional project objectives, such as restoring the riparian buffer with native
vegetation, ensuring hydraulic stability, and treating invasive species.
3e. Describe the overall project in detail, including the type of equipment to be used:
The design approach for the Little Sebastian Mitigation Site is to combine the analog method of
natural channel design with analytical methods to evaluate stream flows and hydraulic
performance of the channel and floodplain. The analog method involves the use of a “template”
stream adjacent to, nearby, or previously in the same location as the design reach. The template
parameters of the analog reach are replicated to create the features of the design reach. The
analog approach is useful when watershed and boundary conditions are similar between the
design and analog reaches. Hydraulic geometry was developed using analytical methods in an
effort to identify the design discharge.
The Little Sebastian Mitigation Site will include priority I stream restoration, enhancement I,
enhancement II, and preservation. Priority I stream restoration will incorporate the design of a
single-thread meandering channel, with parameters based on data taken from reference sites,
published empirical relationships, regional curves developed from existing project streams, and
NC Regional Curves. Analytical design techniques were a crucial element of the project and were
used to determine the design discharge and to verify the design as a whole.
Engineering analysis was performed using various hydrologic and hydraulic models to verify the
reference reach based design. A combination of methods was used to estimate bankfull flows,
and flows corresponding to other significant storm events. A HEC-RAS model was used to
simulate water surface elevations of flows generated by the hydrologic analysis. The development
of the HEC-RAS model is an important component to the design; therefore, model input
parameters are field verified when possible. Through this hydrologic analysis, the design
discharge (typically referenced as bankfull or dominant discharge) was determined. The
subsequent design is based on this calculated discharge. As part of the design process, a
qualitative analysis of sediment supply was performed by characterizing watershed conditions. A
combination of windshield surveys, existing land use data, and historical aerial photography,
followed up by ground truthing, was analyzed to assess existing and past watershed conditions
and to determine if any changes occurred that would significantly impact sediment supply. Design
parameters developed through the analyses of reference reach data, watershed
characterizations, and hydrologic and hydraulic modeling was confirmed using the Sediment

Transport Analysis components within HEC-RAS in conjunction with shear stress and velocity
analyses.
Geomorphic and habitat studies were performed concurrently with the engineering analyses.
While stream design was verified by simulations of hydrology and fluvial processes, analogs of
desirable habitat features were derived from reference sites and integrated into the project design.
Both in-stream and riparian habitat features were designed. In-stream structures will be used
throughout the project to act as grade control and for bank stabilization by dissipating and
redirecting the stream’s energy. Bank stability may further be enhanced through the installation
of brush mattresses, live stakes and cuttings bundles.
Sections of abandoned stream channel will be backfilled with material excavated from onsite to
the elevation of the floodplain in areas adjacent to the new channel, installing channel plugs where
necessary. The floodplain will be planted with native species creating a vegetated buffer, which
will provide numerous water quality and ecological benefits. Stream banks will be stabilized using
a combination of grading, erosion control matting, bare-root plantings, native material revetment
techniques (i.e., bioengineering), structure placement, and sod transplants where possible. The
stream and adjacent riparian areas will be protected by a minimum 30-foot conservation
easement which will be fenced to exclude livestock as needed. In conjunction with the stream
restoration, adjacent wetland hydrology will be enhanced through raising the channel bed. No
wetland mitigation credits will be generated from the enhancement of these wetland areas;
however, the enhancement and protection of these currently degraded wetlands will store excess
water during flood events, prevent erosion of stream banks, and reduce in-stream sedimentation
and nutrients.
The Project has been broken into the following design reaches:
Reach JN2-A - This reach begins on the northwest end of the project, and flows south to JN2-
B. This reach totals 418 linear feet of Preservation. Mature forest is located on both sides of
the reach. Preservation activities will include improving the existing livestock exclusion fencing
and buffers greater than 30 feet. The easement will be extended to provide preservation
beyond the origin point of the stream as per the PJD.
Reach JN2-B - This reach begins on the northwest end of the project, from JN2-A, and flows
south to JN2-C. This reach totals 187 linear feet of Enhancement I. Sparse woodland and
actively managed pasture is located adjacent to the reach. Enhancement activities will include
improving habitat through supplemental buffer plantings and livestock exclusion fencing.
Minimal bank grading and buffer re-establishment is also proposed along the downstream end.
In-stream structures such as log sills and one log cross vane will be installed for stability and
to improve habitat. The restoration of the riparian areas at the downstream end will filter runoff
from adjacent pasture, reduce sediment loads, and provide wildlife corridors throughout the
Project area.
Reach JN2-C - This reach begins on the northwest end of the project, from JN2-B, and flows
south to JN2-D. The reach is divided into two sections by an existing farm crossing and totals
1,144 linear feet of Enhancement II. Sparse woodland and actively managed pasture is located
adjacent to the reach. Enhancement activities will include improving habitat through
supplemental buffer plantings and livestock exclusion fencing. Minimal bank grading and buffer
re-establishment is also proposed along the downstream end. The restoration of the riparian
PCN Supplemental Information-Little Sebastian Mitigation Project

areas at the downstream end will filter runoff from adjacent pasture, reduce sediment loads,
and provide wildlife corridors throughout the Project area.
Reach JN2-D - This reach begins on the northwest end of the project, from JN2-C, and flows
south to MC1-B. The reach is divided into two sections by an existing farm crossing and totals
196 linear feet of Enhancement I. Actively managed pasture is located adjacent to the reach.
Enhancement activities will include some channel relocation, bed and bank stabilization,
removing an existing ford crossing and access road, improving habitat through supplemental
buffer plantings, and livestock exclusion fencing. The restoration of the riparian areas at the
downstream end will filter runoff from adjacent pasture, reduce sediment loads, and provide
wildlife corridors throughout the Project area.
Reach JN3-A – This reach begins on the northwest end of the project, and flows south to JN3-
B. This reach totals 350 linear feet of Enhancement II. Sparse woodland and actively managed
pasture is on the right bank and the left bank has a more mature forest. Enhancement II
activities at a 7.5:1 ratio will include improving habitat through supplemental buffer plantings
and livestock exclusion fencing. The widening and restoration of the riparian areas along the
right bank will filter runoff from adjacent pasture and reduce sediment loads.
Reach JN3-B - This reach begins on the northwest end of the project, from JN3-A, and flows
south to MC1-C. The reach is divided into two sections by an existing farm crossing and totals
1,043 linear feet of Restoration along a gravel/cobble channel (proposed D50 of 50-60 mm).
Sparse woodland and actively managed pasture is located adjacent to the reach. Restoration
activities will include constructing a new channel within the natural valley to the north with
appropriate dimensions and pattern and backfilling the abandoned channel. In-stream
structures such as log sills, brush toes, and log vanes will be installed for stability and to
improve habitat. Habitat will further be improved through buffer plantings and livestock
exclusion. Proposed buffer activities will improve riparian areas that will filter runoff from
adjacent pastures, thereby reducing nutrient and sediment loads to the channel. Also, the
reach will be built through two small jurisdictional wetlands that are currently on the right bank
floodplain and degraded from cattle access and pasture-use. While this project is not claiming
any wetland credit, the raised channel bed should enhance the wetlands’ hydrology by
reconnecting the floodplain wetlands to the stream. Two gauges will be installed on the right
floodplain to monitor the wetland hydrology and will be reported in the yearly monitoring
reports.
Reach MC1-A - This reach begins on the west end of the project, and flows west to MC1-B.
This reach totals 469 linear feet of Enhancement II at a 7.5:1 ratio. Sparse woodland and
actively managed pasture is located on the left bank. Enhancement activities will include
improving habitat through supplemental buffer plantings and livestock exclusion fencing. The
widening and restoration of the riparian areas along the right bank will filter runoff from adjacent
pasture and reduce sediment loads.
Reach MC1-B - This reach begins on the west end of the project, from MC1-A, and flows west
to MC1-C. The reach is divided into two sections by an existing farm crossing and totals 977
linear feet of Enhancement II. Sparse woodland and actively managed pasture is located
adjacent to the reach. Enhancement activities will include improving habitat through
supplemental buffer plantings and livestock exclusion fencing. The widening and restoration of

3i. Comments
Impacts due to the relocation of the stream to natural valley will provide a net gain in ecological
function to the stream and wetland system. Wooded active pasture is located adjacent to these
reach. Restoration is proposed along these reaches to address channel degradation and bank
erosion caused by cattle access. For stream relocation and impacts: Stream Impact 5, the existing
length is 1,124 linear feet (LF), and the new length will be 1,043 LF; Stream Impact 8, the existing
stream length is 545 LF and the new length will be 555 LF; Stream Impact 9, the existing stream
length for the entire reach is 1,547, the new length will be 1,475 LF, however only 1,202 will be
impacted due to stream relocation.
Impacts that are due to the installation of culverts (S1, S2, S3, S4, S6, and S7), where the
permanent impacts include the installation of a 24-inch pipe, and the temporary impacts include
PCN Supplemental Information-Little Sebastian Mitigation Project

a minimum of ten-foot area adjacent to where the culvert will be installed. BS1 will improve a
current culvert (S10).
The impact due to the ford crossing (S11) will include 41 linear feet of a ford crossing installation.

D. Impact Justification and Mitigation
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in
designing project:
Due to the nature of this project, complete avoidance is not possible. Both stream and wetland
impacts were considered when designing the Little Sebastian Mitigation project. This project
should uplift the ecological quality of streams and wetlands on site. The existing project channel
length is 8,189 LF. The proposed project will result in 8,068 LF of stream (see table below).

1b. Specifically describe measures taken to avoid or minimize the proposed impacts
through construction techniques:
Impacts are minimized using a staged construction approach. Where possible the channel will be
constructed prior to turning stream flow into a segment. This approach allows minimization of the
impact of each stage during the project construction. Additionally, all work in wetlands and
streams will be conducted during dry conditions and/or with mats to protect soil structure. Efforts
will be made to preserve individual high value trees located within the stream restoration area.
F. Supplementary Information
8b. If yes, explain how project meets FEMA requirements
According to the North Carolina Floodplain Mapping Information System, the Project includes a
portion of Mill Creek within the FEMA 100-year flood zone (Zone AE). No regulated floodway is
mapped. Hydraulic modeling will be required to determine whether restoration activities will have
an effect on 100-year flood elevations downstream. The design and permitting of the mitigation
will include coordination with the Surry County Floodplain Administrator and a No-Rise
Certification or CLOMR/LOMR will be secured. No hydrologic trespass will be permitted to
adjacent properties upstream or downstream of the project. The Project can be found on Flood
Insurance Rate Map (FIRM) Panel 4946 (map number 3710494600J), effective date August 18,
2009.

Indicate Which of the Following Ap pl :
A. Preliminary Determination
® There appear to be waters, including wetlands on the above described project area/property, that maybe subject to Section 404
of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The
waters, including wetlands have been delineated, and the delineation has been verified by the Corps to be sufficiently accurate
and reliable. The approximate boundaries of these waters are shown on the enclosed delineation map dated 10/27/2017. Therefore
this preliminary jurisdiction determination may be used in the permit evaluation process, including determining compensatory
mitigation. For purposes of computation of impacts, compensatory mitigation requirements, and other resource protection
measures, a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be affected in any
way by the permitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary determination is not an
appealable action under the Regulatory Program Administrative Appeal Process (Reference 33 CFR Part 331). However, you may
request an approved JD, which is an appealable action, by contacting the Corps district for further instruction.
❑ There appear to be waters, including wetlands on the above described project area/property, that may be subject to Section 404
of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC §. 403).
However, since the waters, including wetlands have not been properly delineated, this preliminary jurisdiction determination.
may not be used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is
merely an effective presumption of CWA/RHA jurisdiction over all of the waters, including wetlands at the project area, which
is not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the waters,
including wetlands on your project area/property delineated. As the Corps may not be able to accomplish this wetland
delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps.

1) The Corps of Engineers believes that there may be jurisdictional aquatic resources in the review
area, and the requestor of this PJD is hereby advised of his or her option to request and obtain an
approved JD (AJD) for that review area based on an informed decision after having discussed the
various types of JDs and their characteristics and circumstances when they may be appropriate.
2) In any circumstance where a permit applicant obtains an individual permit, or a Nationwide General
Permit (NWP) or other general permit verification requiring "pre- construction notification" (PCN), or
requests verification for a non -reporting "NWP or other general permit, and the permit applicant has
not requested an AJD for the activity, the permit applicant is hereby made aware that: (1) the permit
applicant has elected to seek a permit authorization based on a PJD, which does not make an official
determination of jurisdictional aquatic resources; (2) the applicant has the option to request an AJD
before accepting the terms and conditions of the permit authorization, and that basing a permit
authorization on an AJD could possibly result in less compensatory mitigation being required or
different special conditions; (3) the applicant has the right to request an individual permit rather than
accepting the terms and conditions of the NWP or other general permit authorization; (4) the applicant
can accept a permit authorization and thereby agree to comply with all the terms and conditions of that
permit, including whatever mitigation requirements the Corps has determined to be necessary; (5)
undertaking any activity in reliance upon the subject permit authorization without requesting an AJD
constitutes the applicant's acceptance of the use of the PJD; (6) accepting a permit authorization (e.g.,
signing a proffered individual permit) or undertaking any activity in reliance on any form of Corps
permit authorization based on a PJD constitutes agreement that all aquatic resources in the review area
affected in any way by that activity will be treated as jurisdictional, and waives any challenge to such
jurisdiction in any administrative or judicial compliance or enforcement action, or in any
administrative appeal or in any Federal court; and (7) whether the applicant elects to use either an AJD
or a PJD, the JD will be processed as soon as practicable. Further, an AJD, a proffered individual
permit (and all terms and conditions contained therein), or individual permit denial can be
administratively appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it
becomes appropriate to make an official determination whether geographic jurisdiction exists over
aquatic resources in the review area, or to provide an official delineation of jurisdictional aquatic
resources in the review area, the Corps will provide an AJD to accomplish that result, as soon as is
practicable. This PJD finds that there "may be" waters of the U.S. and/or that there "may be"
navigable waters of the U.S. on the subject review area, and identifies all aquatic features in the
review area that could be affected by the proposed activity, based on the following information:
