Technical Approach
The Moon Cabin Mitigation Site (Site) is located in Union County, NC, approximately nine miles
southeast of Charlotte, NC (Figure 1). The project includes the restoration of streams and the restoration
and preservation of riparian buffers within the Goose Creek Watershed — Cataloging Unit 03040105 of
the Yadkin River Basin.
The project is located within the Yadkin River Hydrologic Unit Code (HUC) 03040105030020 and NCDWR
Subbasin 03-07-12 and is also within a Targeted Resource Area (TRA) for hydrology, water quality, and
habitat. The two unnamed project streams flow approximately 4,000 feet to their confluence with
Goose Creek, which flows to the Rocky River. According to the 2012 Goose Creek and Crooked Creek
Local Watershed Plan — Phase III (LWP), the Goose Creek watershed is "one of only three watersheds in
North Carolina to still support the Carolina heelsplitter (Lasmigona decorata), a federally and state
endangered freshwater mussel." According to the
report, improving and protecting the health of the
streams in the Goose Creek watershed was
identified as critical in the continued existence of
the Carolina heelsplitter. The proposed stream
and riparian buffer restoration project supports
that goal of improved stream health by addressing
the primary watershed stressors outlined in the
Goose Creek LWP: sediment and bacteria from
agricultural sources and increased peak flows and
runoff volumes. The project also addresses
nutrient inputs and lack of riparian canopy. More
information on the ecological and water quality
goals for the project is included in Table 1.
1.0 Project Goals and Objectives
The major goals of the proposed stream and riparian buffer mitigation project are to provide ecological
and water quality enhancements to the Goose Creek Watershed of the Yadkin River Basin while creating
a functional riparian corridor at the Site. Site stressors include stream incision, active stream erosion,
absent buffers, and areas of limited bedform diversity. Specific enhancements to water quality,
hydrology, and habitat are outlined in Table 1.

2.0 Project Description
The following section describes the existing conditions at the Site in terms of geomorphic condition,
watershed, soils, cultural resources, species of concern, regulated floodplain zones, and Site constraints.
2.1 Existing Site Conditions
Existing Conditions —Riparian Buffer
The Site is on located on one parcel north of West Duncan Road and consists of two unnamed
tributaries; referred to in this proposal as Cabin Creek and UT1 (Figure2). The Site is characterized by a
gently sloped valley dominated by agricultural fields. Based on aerial photos, project streams have been
in the same location since 1938. Historical aerials from 1938 through 2020 are included in the proposal
appendix and further document the Site's long history of agricultural use prior to 2009, the effective
date of the Goose Creek Buffer Rules.
Other than an area of mature trees at the upstream section of Cabin Creek, the area surrounding the
project streams is currently agricultural fields, used to grow corn, wheat, or soybeans. Cabin Creek
originates in a forested corridor offsite. Once it enters the project area, it flows for approximately 300
feet through an area of mature trees before entering into the agricultural field, continuing until it exits
the property at W. Duncan Road. UT1 flows into Cabin Creek from the northwest through an agricultural
field.
Existing Conditions — Streams
In April 2023, the Site streams were evaluated and scored as perennial. Below are brief descriptions of
each of the project streams.
Cabin Creek
Cabin Creek generally flows south through the
Site. The stream originates offsite in a rural
residential area and flows through a forested
riparian area before entering the Site. Onsite,
Cabin Creek flows through a 30-foot wide forested
riparian area for approximately 300 feet before
opening into the agricultural field. The floodplain
is moderately confined with agricultural impacts
extending to the top of bank on both sides. A
narrow strip of herbaceous cover grows along
both stream banks. The channel is incised with
predominantly vertical eroding banks. The stream
bed consists of nearly vertical layers of slate belt
rock peppered with deposits of fines as a result of stream bank erosion, with woody debris occurring
only in the upstream buffer section. Several 6 to 10 inch bedrock knickpoints were observed along the
reach. Farm equipment crosses the stream mid -reach via an unimproved ford crossing.
Moon Cabin Mitigation Site
Wildlands Engineering, Inc. Page 4

UT1
UT1 flows southeast through the Site. UT1 originates in
a mature wooded riparian area near Noah Helms Road
and flows through a narrow buffer consisting of a single
row of trees before entering the Site. Similar to Cabin
Creek, the UT1 channel consists of a mixture of slate
belt rock and deposits of fines with incised, vertical
banks. There is no woody debris present within the
project reach. The valley is wide and flat; a riparian
buffer is non-existent. An unimproved ford crossing at
the upstream extent serves as the farmer's primary
access point between fields. UT1 ends at its confluence
with Cabin Creek.
2.2 Watershed Characterization
The Site topography, as indicated on the Midland, NC USGS 7.5-minute topographic quadrangle, shows
gently sloped areas throughout the Site (Figure 3). The majority of Cabin Creek and all of UT1 are
depicted as streams on the USGS topographic map. Drainage areas for the project features (Figure 4)
were delineated using 2-foot contour intervals derived from the USGS Stream Stats website and the
North Carolina Floodplain Mapping Program's 2014 Light Detection and Ranging (LiDAR) data (Figure 5).
Land uses draining to the project reaches are a mixture of agricultural and forest with some residential
use.
2.3 Soils
The proposed project site is mapped by the Union County Soil Survey. Project area soils are mapped
primarily as Cid channery silt, Goldston very channery silt loam, and Goldston-Badin complex. These
soils are described below in Table 2. An image of the paper copy of the 1996 Soil Survey of Union County
is provided in Figure 6. Both Cabin Creek and UT1 are depicted as streams on the 1996 Soil Survey.

2.4 Cultural Resources and Significant Natural Heritage Areas
The Site is not located near any sites listed on the National Register with the State Historic Preservation
Office (SHPO). The archaeological site files at the North Carolina Office of State Archaeology (OSA) have
not been reviewed at this time. All appropriate cultural resource agencies will be contacted for their
review and comment prior to any land disturbing activity.
Moon Cabin Mitigation Site
Wildlands Engineering, Inc. Page 5

2.5 Threatened and Endangered Species
The National Heritage Program (NHP) Data Explorer database and the US Fish and Wildlife Service
(USFWS) Information for Planning and Consulting (iPaQ database were searched for sensitive species
and critical habitats within and near the project location in Union County, NC. Three federally listed
endangered species were found to be possible in the area: Carolina heelsplitter, Michaux's sumac (Rhus
michauxii) and Schweinitz's sunflower (Helianthus schweinitzii). One proposed endangered species; the
tricolored bat (Perimyotis subflavus) may also be found in the area. No critical habitat or other species of
interest were listed. Wildlands will conduct a review of the Site for federally listed species and
associated habitats upon award of contract.
2.6 Floodplain Compliance
As shown on Union County Flood Insurance Rate
Map (FIRM) Panel 3100, the Site does not contain a
Special Flood Hazard Area (SFHA). The project will be
designed to avoid adverse floodplain impacts or
hydrologic trespass on adjacent properties or local
roads.
2.7 Site Constraints and Access
One external ford crossing is proposed at the Site to
maintain landowner access to a pasture. The crossing is shown on Figure 7. The easement boundaries
around streams proposed for mitigation credit provide the required 50-foot minimum riparian buffer for
Piedmont streams and exceed the 30-foot minimum requirement for riparian buffer mitigation credit.
The entire easement area can be accessed for construction, monitoring, and long-term stewardship
from W. Duncan Road.
3.0 Project Development - Design Approach
Wildlands will begin the project by identifying the best design approach to meet the stated project
objectives and implement the appropriate degree of intervention. A combination of analog, empirical,
and analytical design approaches will potentially be used for stream designs. All project resources will be
designed to create stable, functional stream channels and riparian buffers. The entire Site will be
protected by a conservation easement. The concept design is shown on Figure 7.
3.1 Stream Restoration
Cabin Creek and UT1 are proposed for restoration. Both
reaches are heavily eroded and incised. The reaches will
be designed and built with appropriate dimension,
pattern, and profile to allow for frequent overbank
flooding, provide stable bank slopes, enable biological
lift, and reconnect streams with existing floodplains.
Reference streams will be identified and will serve as
one of the primary sources of information on which
restoration designs are based. Wildlands has developed
a general approach to be used as the basis for stream
restoration design. The design approach, which is
tailored to each Site, continues to develop as additional
projects are implemented.
A short Priority 2 transition zone at the upstream and downstream ends of each reach will be required
to raise the stream beds to a Priority 1 approach.
Moon Cabin Mitigation Site
Wildlands Engineering, Inc. Page 6

Bank revetments such as brush toes will be used to stabilize the outside banks around bends. In -stream
structures will be installed to promote water quality, increase bed and bank stabilization, provide
bedform diversity, and increase aquatic and terrestrial habitat. Wildlands plans to evaluate stream
substrate and determine appropriate gradations/bed features for the Site streams. At this stage,
Wildlands believes most of these channels will be built using a threshold channel approach with a gravel
substrate. The appropriate substrate will be harvested on -site if possible.
3.2 Riparian Buffer Restoration and Preservation
The Wildlands Team proposes to restore a high quality of ecological function to riparian areas on the
Site. The ecological uplift can be summarized as transforming an agriculturally impacted area to a
protected riparian corridor. The project design will avoid adverse impacts to wetlands or existing
riparian buffers. Figure 7 illustrates the conceptual design for the Site. Figure 8 depicts the riparian
buffer zones (30 feet, 50 feet, 100 feet, and 200 feet). Figure 8 also identifies that the project streams
are subject to the Yadkin -Goose Creek Buffer Rules, per the USGS Topographic Map and the NRCS Soil
Survey (Figures 3 and 6).
Buffer restoration will involve planting appropriate native tree species along the riparian corridor. Some
herbaceous riparian vegetation will also be planted, but additional herbaceous plants are expected to
re-establish naturally. Vegetation management may be needed over the first few years of tree
establishment in the riparian buffer restoration areas. There is a small area of existing buffer
preservation at the north end of Cabin Creek that will be protected in perpetuity under the conservation
easement.
The vegetation plan for the Site will include the planting of bare root trees and controlling any future
invasive species populations that impact planted trees. Tree species planted across the buffer areas of
the Site will likely include a mixture of the following species: box elder (Acer negundo), persimmon
(Diospyros virginiana), tulip poplar (Liriodendron tulipifera), river birch (Betula nigro), sycamore
(Platanus occidentalis), swamp chestnut oak (Quercus michauxii), and willow oak (Quercus phellos).
4.0 Proposed Mitigation
The mitigation stream credit calculations were derived using the US Army Corps of Engineers' Stream
Mitigation Guidance and were based on Wildlands' conceptual design for maximum ecological uplift.
Given the existing conditions of the stream channels, the disturbance factors, and the constraints,
management objectives for each reach have been established. The Site will be a consist of stream
restoration at a ratio of 1:1.
The Site is a riparian buffer restoration and preservation site with 402,615.391 ftZof riparian buffer
credits proposed (Table 6b and Figure 7). The mitigation credit calculation was derived based on
Wildlands' conceptual design for maximum ecological uplift.
The management objectives, the mitigation types, and proposed amounts of mitigation are presented in
Table 3a and 3b.

5.0 Current Ownership and Long -Term Protection
The Site is located on one parcel owned by Jimmy Duncan and Carolyn Wesley Duncan (Parcel Number
0825502). The Option Agreement for the project area shown on Figure 7 has been signed by the
property owners and allows Wildlands to purchase a conservation easement on the project property.
Wildlands will convey the conservation easement to the State to provide long term protection of the
Site. The conservation easement agreement will ensure the right of entry abilities of Wildlands, its
contractors, and the future easement holder in any future land transactions.
6.0 Scope of Work and Project Phasing
Table 4 describes the tasks and deliverables required by the Scope of Work outlined in RFQ 16-
20221027. Table 5 provides the proposed schedule for accomplishing each Scope of Work task. The
Wildlands Team has experience handling tightly scheduled projects with multiple stakeholders. We
understand the importance of clear communication and adherence to deadlines. We will establish
additional internal deadlines to keep the project milestones on track. Each task will be staffed with the
appropriate technical and management staff to ensure quality and timely completion.

Performance Standards and Monitoring Plan
The performance criteria for the stream portion of the Site will follow those presented in the
Wilmington District Stream and Wetland Compensatory Mitigation Update by the USACE and the IRT
(October 2016). Restoration reaches will be assigned specific performance criteria components for
hydrology, vegetation, and geomorphology. The buffer portion of the project will follow approved
performance criteria presented in the Mitigation Program Requirements for Protection and
Maintenance of Riparian Buffers (15A NCAC 02B .0295). Annual monitoring and semi-annual site visits
will be conducted throughout the Site to assess the condition of the completed project. Performance
criteria will be evaluated throughout the seven years of post -construction monitoring for the stream
portion of the project and for five years for the buffer portion of the project. The performance criteria
components are as follows.
t4l Moon Cabin Mitigation Site
Wildlands Engineering, Inc. Page 10

7.1 Stream Morphological Parameters and Channel Stability
Dimension
Riffle cross sections on the restoration reaches should be stable and should show little change in
bankfull area, bank height ratio, and width -to -depth ratio. Riffle cross sections should fall within the
parameters defined for channels of the appropriate stream type. If any changes do occur, these changes
will be evaluated to assess whether the stream channel is showing signs of instability. Changes in the
channel that indicate a movement toward stability or enhanced habitat include a decrease in the width -
to -depth ratio in meandering channels or an increase in pool
depth. Remedial action would not be taken if channel changes
indicate a movement toward stability.
In order to assess channel dimension performance, permanent
cross sections will be installed on restoration reaches, and each
cross section will be permanently marked with pins to establish its
location. Cross section surveys will include points measured at all
breaks in slope, including top of bank, bankfull, edge of water, and
thalweg. Cross section and bank pin surveys (if warranted) will be
conducted in monitoring years one, two, three, five, and seven.
Profile and Pattern
Longitudinal profile surveys will only be conducted during the as -built survey, unless indicators during
the annual monitoring indicate a widespread trend toward vertical and lateral instability. If a
longitudinal profile is deemed necessary, monitoring will follow standards as described in the Stream
Channel Reference Sites: An Illustrated Guide to Field Techniques (Harrelson et. al., 1994) for the
necessary reaches.
7.2 Hydrology
Stream
Four bankfull flow events, occurring in separate years, must be documented on the restoration reaches
within the seven-year monitoring period. Stream monitoring will continue until four bankfull events in
separate years have been documented. Bankfull events will be documented using photographs and an
automated pressure transducer. The device will be installed in the stream within a surveyed riffle cross
section. Photographs will also be used to document the occurrence of debris lines and sediment
deposition.
7.3 Vegetation
The final vegetative success criteria for the riparian buffer portion of the project will be the survival of
260 planted stems per acre at the end of the fifth year of monitoring. The final vegetative success
criteria for the stream portion of the project will be the survival of 210 planted stems per acre in the
riparian corridors at the end of the required monitoring period (year seven). The interim measure of
vegetative success for the stream project will be the survival of at least 320 planted stems per acre at
the end of the third monitoring year and at least 260 planted stems per acre at the end of the fifth year
of monitoring. Trees must average seven feet in height at the end of the fifth monitoring year and ten
feet in height at the end of the seventh monitoring year for the stream portion of the project. There is
no height requirement for the buffer mitigation portion of the project. The extent of invasive species
coverage will also be monitored and treated as necessary throughout the required monitoring period.
7.4 Other Parameters
Photo Reference Stations
Photographs should illustrate the Site's vegetation and morphological stability on an annual basis. Cross
section photos should demonstrate no excessive erosion or degradation of the banks. Longitudinal
Moon Cabin Mitigation Site
Wildlands Engineering, Inc. Page 11

photos should indicate the absence of persistent mid -channel bars within the channel or vertical
incision. Grade control structures should remain stable. Deposition of sediment on the bank side of vane
arms is preferable. Maintenance of scour pools on the channel side of vane arms is expected.
Photographs will be taken once a year to visually document project stability following construction.
Permanent markers will be established and documented, so that the same locations and view directions
on the Site are photographed each year. Photos will be used to monitor restoration and enhancement
areas, buffers, and vegetation plots. Photos will be conducted for seven years of post -construction
monitoring for the stream portion of the project and five years for the buffer portion of the project.
Visual Assessments
Visual assessments should support the specific performance standards for each metric as described
above. Visual assessments will be performed within the Site on a semi-annual basis for the duration of
the monitoring periods. Problem areas such as channel instability (e.g., lateral and/or vertical instability,
instream structure failure/instability, piping and/or headcuts), vegetation health (e.g., low stem density,
vegetation mortality, invasive species, or encroachment), or beaver activity, will be noted. Areas of
concern will be mapped, photographed, and documented in the annual report. Problem areas will be re-
evaluated during each subsequent visual assessment. Should remedial actions be required, a plan of
action will be provided in the annual monitoring report.
Benthic Macroinvertebrates
If required by NCDWR as part of the project's permitting process, benthic macroinvertebrate sampling
will be performed on the restored stream portion of the Site. Any required sampling will be performed
using NCDWR Standard Operating Procedures for the Collection and Analysis of Benthic
Macroin vertebrates, February 2016 (Version 5.0).
7.5 Reporting Performance Criteria
The baseline and annual monitoring reports for the stream portion of the project will be submitted and
follow the DMS As -Built Survey Requirement document (October 2020) and the Annual Monitoring
Report Format, Data, and Content Requirements document (October 2020), while the buffer monitoring
report will be based on the DMS Riparian Buffer and Nutrient Offset Buffer Baseline and Annual
Monitoring Report Template version 2.0 (May 2017). The record drawings for both the stream and
buffer portions of the project will follow the DMS Record Drawings Format, Data, and Content
Requirements document (October 2020). Annual monitoring reports will be prepared in the fall of each
monitoring year.
Full monitoring reports for the stream portion of the project will be submitted to DMS in monitoring
years 1, 2, 3, 5, and 7. Abbreviated monitoring reports will be submitted in monitoring years 4 and 6.
Closeout monitoring period will be seven years beyond completion of construction or until performance
standards have been met. Full monitoring reports for the buffer portion will be submitted to DMS in
monitoring years 1-5. The closeout monitoring period will be five years beyond completion of
construction or until performance standards have been met.
7.6 Maintenance and Contingency Plans
The Wildlands Team will develop necessary adaptive measures or implement appropriate remedial
actions if the Site or a specific component of the Site fails to achieve the success criteria outlined above.
The project -specific monitoring plan developed during the design phase will identify an appropriate
threshold for maintenance intervention based on the monitored items. Any actions implemented will be
designed to achieve the success criteria previously specified and will include a work schedule and
updated monitoring criteria (if applicable).
