Mac/Steve,
As discussed, attached is an updated PCN form (with updated impacts) and plan sheet showing an added log sill at Sta.
3+00 to address the head cut and extended limits of grading on Reach DWI -A up to Sta. 2+75. Also the vane at Sta 3+50
from the original plan sheet has been updated to a riffle.
As a reminder, the original sheet had limits of grading stopping at Sta 3+20 and a log vane at Sta 3+50. We are not
proposing an increase in credits on this reach for the added work. It is captured on the PCN as stream impact "S8" with
45 feet of temporary impact. Please let me know if you need anything else to process. Apologies for the back and forth
on this one.
Thanks,
Brad Breslow

PCN Supplemental Information — Compass Point Mitigation Project
B. Proiect Information and Prior Proiect Histor
3a. Describe the existiniz conditions on the site and the zeneral land use in the vicinity of the proiect at
the time of this application:
The Compass Point Mitigation Site ("Project") is located within a rural watershed in Yadkin County,
approximately 4.5 miles northeast of Boonville. The Project lies within the Yadkin River Basin, North
Carolina Department of Water Resources (NCDWR) sub -basin 03-07-02 and United States Geological
Survey (USGS) 12 -digit hydrologic unit code (HUC) 03040 101100 1. The total drainage area for the Project
is 271 acres (0.42 mi2). Primary land use within the rural watershed consists of approximately 60.4 percent
forest and 33.7 percent agricultural land. Impervious area covers less than one percent of the total watershed
Within the agricultural land use, pastureland accounts for 62.5 percent of the area, and row crops account
for approximately 37.5 percent of the area. Although the project watershed is primarily forested, the
majority of the agricultural areas within the watershed are in close proximity to the Project and play a
significant role in the degradation of the Project streams. These activities have negatively impacted both
water quality and streambank stability along the Project streams and their tributaries. The resulting observed
stressors include excess nutrient input, streambank erosion, sedimentation, livestock access to streams,
channel modification, and the loss of riparian buffers.
The Project area is comprised of a contiguous easement area along three unnamed tributaries that converge
and drain directly to the Yadkin River. The easement has two agricultural crossings; one between DWI -C
and DW 1-B, and the second easement break is on DW2-B near the confluence with DW 1-A. The stream
channels include the main unnamed tributary and two additional tributaries that converge from the east,
then split into eight reaches based on proposed treatment type.
In general, all or portions of all eight Project reaches 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 up to the edge of the existing channel or comprised largely of invasive species. In some
reaches, trees are present, 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.
PCN Supplemental Information — Compass Point Mitigation Project
3e. Describe the overall oroiect in detail. including the tune of eauinment to be used.
Stream restoration efforts along the tributaries of the Project will be accomplished through analyses of
geomorphic conditions and watershed characteristics. The design approach applies a combination of
analytical and reference reach -based design methods that meet objectives commensurate with both
ecological and geomorphic improvements. Proposed treatment activities may range from minor bank
grading and planting to re-establishing stable planform and hydraulic geometry. For reaches requiring full
restoration, natural design concepts have been applied and verified through rigorous engineering analyses
and modeling. The objective of this approach is to design a geomorphically stable channel that provides
habitat improvements and ties into the existing landscape.
The Project will include priority I and II stream restoration, enhancement 1, enhancement II, and
enhancement III. Stream restoration will incorporate the design of a single -thread meandering channel, with
parameters based on data taken from reference sites, published empirical relationships, and best
professional judgment.
Engineering analysis will be performed using various hydrologic and hydraulic models to verify the
design. A combination of methods will be used to estimate bankfull discharge, and larger flood events. A
HEC -RAS model will then be used to simulate water surface elevations of flows generated by the
hydrologic analysis. The development of the HEC 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) will be determined. The
subsequent design will be based on this calculated discharge. As part of the design process, a qualitative
analysis of sediment supply will be performed by characterizing watershed conditions. A combination of
windshield surveys, existing land use data, and historical aerial photography, followed up by ground
truthing, will be 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
will be confirmed with shear stress and velocity analyses.
Geomorphic and habitat studies will be performed concurrently with the engineering analyses. While
stream design will be verified by simulations of hydrology and fluvial processes, analogs of desirable
habitat features will be derived from reference sites and integrated into the project design. Both in -stream
and riparian habitat features will be 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 toes, 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 50 -foot conservation easement which will be fenced to
exclude livestock as needed.
PCN Supplemental Information — Compass Point Mitigation Project
The Project has been broken into the following design reaches:
Reach DW1-A - This reach begins on the southwest end of the Project, flows northeast to a confluence
with DW1-B and DW2-13, and totals 288 linear feet of Enhancement II. Open pasture is located adjacent
to the reach. Enhancement activities will include improving habitat through livestock exclusion fencing
and riparian planting. The livestock exclusion fencing will provide wildlife corridors throughout the
Project area and will remove livestock access to the riparian areas. A flow gauge will be installed midway
on the reach to monitor hydrology.
Reach DW1-B - This reach begins on the southern end of the Project from DWI -A and DW2-B, flows
north to DWI -C, and totals 1,922 linear feet of Priority I/II restoration. Actively managed pasture is
located adjacent to the reach on the upstream end. The downstream end is surrounded by intermittently
grazed pasture and disturbed secondary growth in an area with previous timber harvest. Restoration
activities will include constructing a new channel within the natural valley 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.
Reach DW1-C — This reach begins on the north end of the Project from DWI -B, and flows northeast to a
culvert crossing and DWI -D. This reach totals 566 linear feet of Priority VII restoration, beginning
immediately downstream of a bedrock drop structure at the bottom of DW 1-B. Any sections of the
existing road will be decommissioned in the easement and planted. Intermittently active pasture and
disturbed woodland is located adjacent to the reach. Restoration activities will include constructing a new
channel within the natural valley with appropriate dimensions and pattern, cutting a floodplain bench 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. Livestock exclusion fencing will provide wildlife corridors throughout the
Project area and will remove livestock access to the riparian areas.
Reach DW1-D - This reach begins at the downstream end of DWI -C and proposed culvert crossing in
the northern end of the Project, and flows northeast to DWI -E. The reach totals 759 linear feet of Priority
VII restoration. Restoration activities will include constructing a floodplain bench to aid in connectivity to
the existing floodplain and constructing a new channel with appropriate dimensions and pattern. When
possible, bed material will be harvested and reused to create stable bed features post -construction. 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.
Reach DW1-E - This reach begins on the north end of the Project, from DWI -D and flows north until it
drains to the Yadkin River. This reach totals 432 linear feet of Enhancement III. Managed cropland is
located adjacent to the reach. Enhancement activities will include improving habitat through livestock
exclusion fencing and installing a boulder grade control structure at the top of the reach where DWI -D
enters to prevent further upstream channel erosion during Yadkin River flood events.
Reach DW2-A - This reach begins on the southeast end of the Project, and flows west to DW2-B. The
totals 968 linear feet of Enhancement I. Sparse woodland and actively managed pasture is located
PCN Supplemental Information — Compass Point Mitigation Project
adjacent to the reach. Enhancement activities will include targeted bank stabilization, riparian buffer
planting, and installation of livestock exclusion fencing. An existing ford crossing will also be removed.
Proposed buffer activities will improve riparian areas that will filter runoff from adjacent pastures,
thereby reducing nutrient and sediment loads to the channel.
Reach DW2-B - This reach begins at the downstream end of DW2-A, and flows north to the confluence
with DWI -A to become DWI -B. This reach totals 277 linear feet of Priority I 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 ford crossing will be installed along this reach
(Figure 10). Proposed buffer activities will improve riparian areas that will filter runoff from adjacent
pastures, thereby reducing nutrient and sediment loads to the channel.
Reach DW3 - This reach begins on the south end of the Project at the adjacent powerline easement, and
flows north to DW2-A. This reach totals 93 linear feet of Enhancement I. Disturbed woodland,
intermittently grazed pasture, and a maintained powerline easement is located adjacent to the reach.
Enhancement activities will include improving habitat through livestock exclusion fencing, and riparian
buffer planting. The livestock exclusion fencing will provide wildlife corridors throughout the Project
area and will remove livestock access to the riparian areas.

3i. Comments
Impacts due to the relocation of the stream to natural valley will provide a net gain in ecological function
to the stream system. Active pasture is located adjacent to all project reaches. Restoration is proposed along
several reaches to address channel degradation and bank erosion caused by cattle access (DW1-B, DWI -
C, DWI -D, and DW2-B). For stream relocation and impacts: Stream Impact 1, the existing length is 514
linear feet (LF), and the new length will be 485 LF; Stream Impact 4, the existing stream length is 2,014
LF and the new length will be 1,922 LF; Stream Impact 5, the existing stream length is 600 LF, the new
length will be 566 LF; Stream Impact 7, the existing stream length is for the entire reach is 741, however,
only 415 LF will be impacted.
There are two impacts associated with the installation of a culvert (S5 and S6), where the permanent impacts
include the installation of a 24 -inch pipe, and the temporary impacts are due to earthwork movement
adjacent to culvert location. Additionally, there is one permanent impact (S2) associated with the
installation of a ford crossing.
D. Impact Justification and Mitigation
]a. Specifically describe measures taken to avoid or minimize the proposed impacts in desieninje proiect.
Due to the nature of this project, complete avoidance is not possible. Both stream and wetland impacts
were considered when designing the Compass Point Mitigation project. This project should uplift the
ecological quality of streams and wetlands on site. The existing project channel length is 5,350 LF. The
proposed project will result in 5,304 LF of stream.
Ib. Specifically describe measures taken to avoid or minimize the proposed impacts throu,-h 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 proiect meets FEMA requirements
According to the North Carolina Floodplain Mapping Information System, the Project includes a portion
of the of Project within the FEMA 100 -year flood zone (Zone AE, one percent annual chance of
flooding). Reaches DWI -E and DWI -D, where the Project connects to the Yadkin River, is in a regulated
floodway zone. 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 Yadkin 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 37171C (map number 3710590000K), effective date August 18, 2009.
Aquatic Resources Table Update
Stream IDs have changed during the design process. From the original JD submittal, DWI -A has been
broken out into the design reaches DW2-B and DW1-B. This change in naming changed the subsequent
naming convention along the main tributary of the project. From the original submittal the following have
been changed: DWI -B is now DWI -C; DWI -C is now DWI -D; DWI -D is now DWI -E; DW2 is now
DWI -A; DW6 is now DW2-A; and DW3 was added into the project.
