RE: Nationwide 27 Permit Application for the Compass Point Mitigation Site
Dear Mr. Haupt,
Resource Environmental Solutions (RES) is pleased to submit a Nationwide Permit 27 Pre-Construction
Notification (PCN) for the Compass Point Mitigation Site (Project). The Project is located within a
watershed dominated by agricultural, forested and low-density residential land use approximately 4.5 miles
northeast of Boonville, North Carolina. The Project area exhibits reduced hydrology and habitat value as a
result of past and on-going agricultural activities. The Project will involve the restoratio n, enhancement,
and preservation of three streams in the Yadkin River Basin.
The objective for this mitigation project is to restore and design natural waterways through stream
complexes with appropriate cross-sectional dimension and slope that will provide function and meet the
appropriate success criteria agreed upon in the mitigation plan. Accomplishing this objective entails the
restoration of natural stream characteristics, such as stable cross sections, pla nform, and in-stream habitat.
The floodplain areas will be hydrologically reconnected to the channel to provide natural exchange and
storage during flooding events. Total wetland impacts resulting from the proposed project are 0.05 acres.
Total stream impacts resulting from the proposed project are 3,380 linear feet. There are no DWR buffers
on this Project.
The attached PCN package includes PCN Form, PCN supplemental information, supporting figures, an
updated PJD with an updated aquatic resource inventory table and Waters of the US Map.
Thank you for your prompt attention to this important project. Please contact me at 919-209-1066 or
[e-mail] if you have any questions or require any additional information.
Sincerely,

4a. 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 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)
030401011001. The total drainage area for the Project is 271 acres. 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 rowcrops
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 DW1-C
and DW1-B, and the second easement break is on DW2-B near the confluence with DW1-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.

4h. 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.
41. Describe the overall project in detail, including indirect impacts and the type of equipment 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 I, 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 streams 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.
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 DW1-13 and DW2-B, 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. Aflow 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 DW1-A and DW2-B, flows north to DW1-C, and totals 1,922 linear feet of Priority VII 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 DW1-B, and flows northeast to a culvert crossing and DW1-D. This reach totals 566 linear feet of Priority VII
restoration, beginning immediately downstream of a bedrock drop structure at the bottom of DW1-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 newchannel 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 DW1-C and proposed culvert crossing in the northern end of the Project, and flows northeast to DW1-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 newchannel
with appropriate dimensions and pattern. When possible, bed material will be harvested and reused to create stable bed features post -construction. Instream 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 DW1-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 DW1-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 DW1-A to become DW1-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.

3j. 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, DW1-C, DW1-D, and DW2-B). For stream relocation and impacts: Stream Impact 1, the existing length is 306 linear feet (LF),
and the new length will be 277 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 8, the existing stream length is for the entire reach is 741, however,
only 487 LF will be impacted.
There are two impacts associated with the installation of a culvert (S6 and S7), 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.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
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.
1 b. 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.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
f Yes r No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
This project is a restoration project. Utimately, there will be an increase in water and ecological quality of streams and wetlands within the project, due to restoration and enhancement
of the streams and wetlands, planting of the riparian buffer, excluding livestock, and the establishment of a conservation to be protected in perpetuity.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?

Action ID: SAW -2017-01465 County: Yadkin U.S.G.S. Quad: Copeland
NOTIFICATION OF JURISDICTIONAL DETERMINATION
Property Owner: Donnie Wagoner
Address: 4650 Pulliam Rd.
Boonville, NC 27011
Telephone Number:
Size (acres): 14 Nearest Town Boonville
Nearest Waterway: UT to Yadkin River Coordinates: 36.269624, 4013914.995077
River Basin/ HUC: Upper Pee Dee
Location description: The site is located at 4650 Pulliam Rd. in Boonville, NC.
Indicate Which of the Following Apply:
A. Preliminary Determination
X There are waters, including wetlands, on the above described project area, 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). The
waters, including wetlands, have been delineated, and the delineation has been verified by the Corps to be sufficiently
accurate and reliable. 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 are wetlands on the above described 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 overall 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 of the U.S. on your 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.
B. Approved Determination
_ There are Navigable Waters of the United States within the above described property subject to the permit requirements
of Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act (CWA)(33
USC § 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for
a period not to exceed five years from the date of this notification.
_ There are waters of the U.S. including wetlands on the above described property subject to the permit requirements of
Section 404 of the Clean Water Act (CWA)(33 USC § 1344). Unless there is a change in the law or our published
regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification.
_ We recommend you have the waters of the U.S. on your 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.
_ The waters of the U.S. including wetlands on your project area have been delineated and the delineation has been
verified by the Corps. If you wish to have the delineation surveyed, the Corps can review and verify the survey upon
completion. Once verified, this survey will provide an accurate depiction of all areas subject to CWA and/or RHA
jurisdiction on your property which, provided there is no change in the law or our published regulations, may be relied
upon for a period not to exceed five years.

X The waters of the U.S. including wetlands have been delineated and surveyed and are accurately depicted on the plat
signed by the Corps Regulatory Official identified below on . Unless there is a change in the law or our published
regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification.
There are no waters of the U.S., to include wetlands, present on the above described project area which are subject to the
permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our
published regulations, this determination may be relied upon for a period not to exceed five years from the date of this
notification.
X The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act
(CAMA). You should contact the Division of Coastal Management to determine their requirements.
Placement of dredged or fill material within waters of the US and/or wetlands without a Department of the Army permit may
constitute a violation of Section 301 of the Clean Water Act (33 USC § 1311). Placement of dredged or fill material,
construction or placement of structures, or work within navigable waters of the United States without a Department of the
Army permit may constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act (33 USC § 401 and/or 403). If
you have any questions regarding this determination and/or the Corps regulatory program, please contact William Elliott at
828-271-7980, ext. 4225 or [e-mail].
C. Basis for Determination:
See attached preliminary jurisdictional determination form.
The site contains wetlands as determined by the 1987 Corps of Engineers Wetland Delineation Manual and the
Regional Supplement to the Corps of Engineers Wetlands Delineation Manual: Eastern Mountain and Piedmont
Region (version 2.0). These wetlands are adjacent to stream channels located on the property that exhibit indicators
of ordinary high water marks.
D. Remarks:
The potential waters of the U.S., at this site, were verified on-site by the Corps on 1/24/2018 and are as approximately
depicted on the attached Potential Wetland/Waters Map (dated 11/29/2017)
E. Attention USDA Program Participants
This delineation/determination has been conducted to identify the limits of Corps' Clean Water Act jurisdiction for the
particular site identified in this request. The delineation/determination may not be valid for the wetland conservation
provisions of the Food Security Act of 1985. If you or your tenant are USDA Program participants, or anticipate
participation in USDA programs, you should request a certified wetland determination from the local office of the
Natural Resources Conservation Service, prior to starting work.

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 asjurisdictional, and waives any challenge to such jurisdiction in any
administrative orjudicial 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:
