PCN Supplemental Information -Gideon Mitigation Project
B. Proiect Information and Prior Proiect Histor
3a. Describe the existing conditions on the site and the general land use in the vicinity of the proiect at
the time of this application:
The Gideon Mitigation Project ("Project") 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 3,191 -acre drainage area of the project, the primary land use within the drainage area consists
of approximately 89 percent forest, 10 percent agricultural land, and less than one percent of the total
watershed is impervious surface.
The Project area is comprised of one easement areas along Mill Creek; totaling 11.22 acres and 4,614
existing linear feet of stream. This project lies between the western and eastern portion of the North Carolina
Division of Mitigation Services ("NCDMS") Little Sebastian Mitigation Project. There are three easement
breaks; one between JN4-A and JN4-B, that is an existing road that will be maintained, and is approximately
73 feet wide; the second easement break is between JN6-A and JN6-B, that is an existing road that will be
maintained, and is approximately 28 feet wide; the third easement break is between JN6-B and JN6-C, that
will be a culvert, and is approximately 31 feet wide. The stream channels include Mill Creek and three
unnamed tributaries, split into eight 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 northwest of the project.
In general, all or portions of JN4-A, JN4-B, JN5, JN6-B, JN6-C, MC2-A, and MC2-13 do not function to
their full potential; whereas JN6-A seems to have functionality and is proposed for preservation only.
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, the but understory riparian buffer has been heavily
impacted by cattle. Habitat along the majority 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 proiect:
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 proiect in detail, including the type of equipment to be used.
The design approach for the Gideon Mitigation Project 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
PCN Supplemental Information -Gideon Mitigation Project
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 Project will include priority I stream restoration, enhancement I, enhancement III, and preservation.
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 are also a crucial element
of the project used to determine the design discharge and to verify the design as a whole.
Engineering analyses were performed using various hydrologic and hydraulic models to verify the
reference reach based design and to estimate bankfull flows, and flows corresponding to other significant
storm events. As part of the design process, a qualitative analysis of sediment supply was performed by
characterizing watershed conditions through a study of existing land use data and historical aerial
photography, followed up by ground truthing. Design parameters developed through the analyses of
reference reach data, watershed characterizations, and hydrologic and hydraulic modeling were confirmed
using HEC -RAS in conjunction with shear stress and velocity analyses.
Geomorphic and habitat studies were performed concurrently with the engineering analyses. While the
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. 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 on site 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 JN4-A - This reach begins on the southwest end of the project, flows east to JN4-B, and totals
213 linear feet of Enhancement III. Woodland is located adjacent to the reach. Enhancement activities
will include improving habitat through livestock exclusion fencing and light supplemental planting.
The livestock exclusion fencing will provide wildlife corridors throughout the Project area and will
remove livestock access to the riparian areas.
Reach JN4-B - This reach begins on the southwest end of the project from JN4-A, flows east to JN5,
and totals 264 linear feet of Enhancement I. Actively managed pasture is located adjacent to the
reach. Enhancement activities will include removing pipe in old channel, fixing current culvert,
grading banks, installing grade control structures, planting the buffer, and cattle exclusion. The
PCN Supplemental Information -Gideon Mitigation Project
livestock exclusion fencing will provide wildlife corridors throughout the Project area and will
remove livestock access to the riparian areas.
Reach JN5 — This reach begins on the southern end of the project, and flows northeast to MC2-13.
This reach totals 248 linear feet of Enhancement I. 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, and a grade control structure will be installed at the tie-in with
MC2-A. 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 JN6-A - This reach begins on the northern end of the project, near Wetland G, and flows south
to JN6-B. The reach totals 508 linear feet of Preservation. Dense woodland is located adjacent to the
reach. Preservation activities will include improving habitat through the construction of livestock
exclusion fencing and supplemental planting of the left bank. There will be no impact to Wetland G,
as the reach is Preservation and will not have any ground disturbance.
An easement break is proposed at the break with JN6-A and JN6-B and is an old road. Stabilization
measures on the road will likely include installing one to two water bars, and possibly some minor
grading and stone.
Reach JN6-B - This reach begins on the north end of the project, from JN6-A and flows south to
JN6-C through Wetland D. This reach totals 707 linear feet of Enhancement III. Dense woodland is
located adjacent to the reach. Enhancement activities will include improving habitat through livestock
exclusion fencing, and removing the livestock crossing. The livestock exclusion fencing will provide
wildlife corridors throughout the Project area and will remove livestock access to the riparian areas.
There might be temporary impacts in Wetland D, due to the removal of the livestock crossing at the
end of Reach JN6-B. However, Wetland D will ultimately have a functional uplift, increasing
hydraulic function in the wetland due to the crossing removal. All wetland impacts will be accounted
for in the Pre -Construction Notification form.
Reach JN6-C - This reach begins on the southern end of the project, from JN6-B, and flows
southeast to MC2-13 through Wetland E. This reach will be 1,243 linear feet of Restoration and the
southern portion of JN6-C will be realigned through Wetland F back to its historic location. Sparse
woodland and actively managed pasture is located adjacent to the reach. Restoration activities will
include constructing a new channel with appropriate dimensions and pattern and backfilling the
abandoned channel. In -stream structures such as log sills, log 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.
There will be temporary impacts in Wetland E and Wetland F, due to the construction activities of
JN6-C. Cattle currently have access to these wetland areas and will be fenced out post construction.
The reach and wetlands are 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. Three gauges will be installed along this reach to
monitor the wetland hydrology and will be reported in the yearly monitoring reports. All wetland
impacts will be accounted for in the Pre -Construction Notification form.
PCN Supplemental Information -Gideon Mitigation Project
An easement break is proposed near the upper end of the reach to improve a crossing. The existing
culvert will be removed and replaced with 24 linear feet of 30" RCP. Additionally, the two small
buildings located adjacent to the easement break will be removed.
Reach JN7 — Reach JN7 begins downstream of Wetland F adjacent to the floodplain of MC2-B.
Realignment of Reach JN6-C will include the jurisdictional length of JN7 in its entirety.
Reach MC2-A - This reach begins at the west end break of the NCDMS Little Sebastian Site, and
flows southeast to MC2-13. This reach totals 1,045 linear feet of restoration. Actively managed
pasture is present on both sides of the reach. Restoration activities will include constructing a new
channel within the natural valley with appropriate dimensions pattern and backfilling the abandoned
channel. Native bed material will be harvested when possible. 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. A crossing with a culvert will be installed
along this reach. Proposed buffer activities will improve riparian areas that will filter runoff from
adjacent pastures, thereby reducing nutrient and sediment loads to the channel. The NCDMS Little
Sebastian Site will be constructed in tandem with the project.
Reach MC -2B -This reach begins on the east end of the project, from MC2-C, and flows east to
MC3-A on the Little Sebastian Mitigation Site. This reach totals 578 linear feet of Enhancement III.
Woodland is located adjacent to the reach. Enhancement activities will include improving habitat
through livestock exclusion fencing and planting the buffer on the left bank. The livestock exclusion
fencing will provide wildlife corridors throughout the Project area and will remove livestock access to
the riparian areas. The Little Sebastian Site will be constructed in tandem with the project.

C. Proposed Impacts Inventory
2h. Comments
Wetland impacts associated with restoration efforts occurring adjacent to the existing wetlands will be
minimized by the restoration plan. Creating a new stream channel and enhancing existing channels will
only impact wetlands slightly and will provide an overall increase in wetland function with the addition of
native trees and shrubs along the stream banks. There will be a total of 0.576 acres of wetland impacts, of
which 0.444 acres will be temporary impacts, and 0.132 acres will be permanent impacts.
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. Active pasture and wooded active pasture is located adjacent to all project
reaches. Restoration is proposed along these reaches to address channel degradation and bank erosion
caused by cattle access. For stream relocation and impacts: Stream Impact 1, the existing length is 1,110
linear feet (LF), and the new length will be 1,045 LF; Stream Impact 4 the existing stream length is 964 LF
and the new length will be 1,243 LF; Stream Impact 5, the existing stream length for the entire reach is 55
LF however, due to the re -alignment of JN6-C will include the jurisdictional length of JN7 its entirety.
Impacts that are due to the installation of culverts (S2 and S3), where the permanent impacts include the
installation of a 24 LF of 30 -inch pipe, and the temporary impacts include a minimum of seven -foot area
adjacent to where the culvert will be installed.
D. Impact Justification and Mitigation
la. 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 Gideon Mitigation project. This project should uplift the ecological quality
of streams and wetlands on site. In one instance, instead of working within Wetland F and causing
significant temporary impacts, restoration work will only occur where necessary along JN6-C within the
Wetland F, and be allowed to restore naturally. Although we are showing permanent impacts along the
centerline of JN6-C within Wetland F and in the few grading areas, it is anticipated that ecological uplift will
occur within Wetland F by providing additional hydrologic connectivity.
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, one percent annual chance of flooding.
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
PCN Supplemental Information -Gideon Mitigation Project
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.
