RE: Compass Point Year 3 Monitoring Report (SAW-2017-01465 | RES Yadkin 01 Umbrella Mitigation
Bank)

Mr. Kichefski,

Please find attached the Compass Point MY3 Monitoring Report. In Year 3, 11 of 11 vegetation plots met
the 320 stems per acre success criteria. Stem densities ranged from 324 to 1,093. Two bankfull events were
recorded now in each of the four years of monitoring on the stage recorder on DW1-B. The flow gauge on
DW1-A recorded consecutive flow for 220 days in 2023. Maintenance activities for this upcoming dormant
season include supplemental planting the two low stem density areas from MY2 and livestaking two areas
of bank erosion on DW1-C. Comments from the MY2 Monitoring Report are addressed below and in the
report.
1. Please continue to track previous/ongoing project comments/concerns as separate bullets throughout
the monitoring period.
Noted.

2. When addressing supplemental planting during this dormant season, consider the opportunity for
increasing species diversity as mentioned in previous comments.
When determining species to purchase for a supplemental planting we aways consider the species
diversity on site along with the species that are in the approved planting plan.

3. Thank you for providing the photo station and updated description of culvert substrate and stability. In
future photos, please try to capture the culvert outlet in a way to help show the substrate/stability.
Noted.

4. Is a mid-channel bar forming at Cross Section 14?
There is vegetation growing in the channel at and downstream of Cross Section 14. This is likely due to
aggradation caused by backwater from the Yadkin River

5. Table 11 shows 320 maximum consecutive days of flow for DW1-A, yet the hydrograph on the next
page shows 221 days of consecutive flow, please clarify?
The 221 days on the hydrograph was an error.

RES is requesting a 10% stream credit release (415.500 SMUs) for the completion of the MY3 report. Please
see the enclosed credit release timeline and an updated credit ledger.

Thank you,

Katie Obenauf | Ecologist

Mitigation Site September 2023
1.0 Project Summary

1.1 Project Location and Description

The Compass Point Mitigation Site (“the Project”) is located in Yadkin County, approximately 4.5
miles northeast of Boonville. Water quality stressors that affected the Project included livestock
production, agricultural production, and lack of riparian buffer. The Project presents 5,289 linear
feet (LF) of stream restoration and enhancement generating 4,155 Cool Stream Mitigation Units
(SMU) along three unnamed tributaries that drain directly to the Yadkin River.

The Project is located in the Yadkin River Basin within Cataloging Unit 03040101, Target Local
Watershed 030401011001, and NCDWR sub-basin 03-07-02. The current State classification for
the Yadkin River at this location is Class C (NCDWR 2011).

The Project’s total easement area is approximately 16.46 acres within the overall drainage area of
271 acres and consisted of cattle pastures and wooded areas. Grazing livestock historically had
access to most stream reaches within the Project. The lack of riparian buffer vegetation, deep-
rooted vegetation, and unstable channel characteristics had contributed to the degradation of
stream banks throughout the Project area.

The stream design approach for the Project combined 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 involved the use of a reference reach, or “template” stream,
adjacent to, nearby, or previously in the same location as the design reach. The template
parameters of the analog reach were 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 (Skidmore et al., 2001). Hydraulic geometry was developed using
analytical methods to identify the design discharge.

The Project will be monitored on a regular basis throughout the seven-year post-construction
monitoring period, or until performance standards are met. Upon approval for closeout by the
Interagency Review Team (IRT), the site will be transferred to Unique Places to Save (UP2S). This
party shall serve as conservation easement holder and long-term steward for the property and
will conduct periodic inspection of the site to ensure that restrictions required in the conservation
easement are upheld. Endowment funds required to uphold easement and deed restrictions will
be finalized prior to site transfer to the responsible party.

1.2 Project Goals and Objectives

Through the comprehensive analysis of the Project’s maximum functional uplift using the Stream
Functions Pyramid Framework, specific, attainable goals and objectives will be realized by the
Project. These goals clearly address the degraded water quality and nutrient input from farming
that were identified as major watershed stressors in the 2009 Upper Yadkin Pee-Dee River RBRP.

Compass Point 3 Year 3 Monitoring Report
Mitigation Site September 2023
The Project goals are:
· Improve water transport from watershed to the channel in a non-erosive manner in a
stable channel;
· Improve flood flow attenuation on site and downstream by allowing for overbank flows
and connection to the active floodplain;
· Improve instream habitat;
· Restore and enhance native floodplain vegetation; and
· Indirectly support the goals of the 2009 Upper Yadkin Pee-Dee RBRP to improve water
quality and to reduce sediment and nutrient loads.
The Project objectives to address the goals are:
· Designed and reconstructed stream channels sized to convey bankfull flows that will
maintain a stable dimension, profile, and planform based on modeling, watershed
conditions, and reference reach conditions;
· Added in-stream structures and bank stabilization measures to protect restored and
enhanced streams;
· Installed habitat features such as brush toes, constructed riffles, woody materials, and
pools of varying depths to restored and enhanced streams;
· Reduced bank height ratios and increased entrenchment ratios to reference reach
conditions;
· Increased forested riparian buffers to at least 50 feet on both sides of the channel along
the Project reaches with a hardwood riparian plant community;
· Treated exotic invasive species; and
· Established a permanent conservation easement on the Project that excludes livestock
from stream channels and their associated buffers.

Limitations to achieving these watershed goals arise by remaining constrained to the project
boundaries. While we are restoring the habitat and streams to stable and effective conditions that
achieve our goals within the Project parcels, we are unable to influence the effect of all riparian
buffers and livestock impact in other areas within the watershed. However, with responsible
restoration and stewardship of the majority of reaches within this small watershed, overall
watershed functionality and health will improve to meet the RBRP goals.

1.3 Project Success Criteria

The Project follows the USACE 2003 Stream Mitigation Guidelines, and the “Wilmington District
Stream and Wetland Compensatory Mitigation Update” dated October 24, 2016. Cross section
and vegetation plot data will be collected in Years 0, 1, 2, 3, 5, and 7. Hydrology data and visual
monitoring will be reported annually.

Compass Point 4 Year 3 Monitoring Report
Mitigation Site September 2023
Stream Success Criteria

Four bankfull flow events must be documented within the seven-year monitoring period. The
bankfull events must occur in separate years. Otherwise, the stream monitoring will continue until
four bankfull events have been documented in separate years.

There should be little change in as-built cross sections. If changes do take place, they should be
evaluated to determine if they represent a movement toward a less stable condition (for example
down-cutting or erosion) or are minor changes that represent an increase in stability (for example
settling, vegetative changes, deposition along the banks, or decrease in width/depth ratio). Cross
sections shall be classified using the Rosgen stream classification method, and all monitored cross
sections should fall within the quantitative parameters defined for channels of the design stream
type. Bank height ratio shall not exceed 1.2, and the entrenchment ratio shall be no less than 1.4
within restored reaches. The entrenchment ratio shall be no less than 2.2 for all measured riffle
cross-sections on a given reach. Channel stability should be demonstrated through a minimum of
four bankfull events documented in the seven-year monitoring period.

Digital images are used to subjectively evaluate channel aggradation or degradation, bank
erosion, success of riparian vegetation, and effectiveness of erosion control measures.
Longitudinal images should not indicate the absence of developing bars within the channel or an
excessive increase in channel depth. Lateral images should not indicate excessive erosion or
continuing degradation of the banks over time. A series of images over time should indicate
successional maturation of riparian vegetation.

Vegetation Success Criteria

Specific and measurable success criteria for plant density within the riparian buffers on the
Project follow IRT Guidance. Vegetation monitoring plots are a minimum of 0.02 acres in size
and cover a minimum of two percent of the planted area. The interim measures of vegetative
success for the Project are the survival of at least 320 planted three-year old trees per acre at the
end of Year 3, at least 260 planted five-year old trees at seven feet in height at the end of Year
5, and the final vegetative success criteria is at least 210 trees per acre with an average height of
ten feet at the end of Year 7. Volunteer trees are counted, identified to species, and included in
the yearly monitoring reports, but did not count towards the success criteria of total planted
stems. Moreover, any single species can only account for up to 50 percent of the required
number of stems within any vegetation plot. Any stems in excess of 50 percent are shown in the
monitoring table but were not used to demonstrate success.

1.4 Project Components

The Project area is comprised of a single easement location along three unnamed tributaries to
the Yadkin River, totaling 5,289 linear feet. There are eight stream reaches, DW1-A, DW1-B, DW1-
C, DW1-D, DW1-E, DW2-A, DW2-B, and DW3, divided by treatment type. The Project is accessible

Compass Point 5 Year 3 Monitoring Report
Mitigation Site September 2023
from Pulliam Road. The stream mitigation components are summarized below. The one minor
change from the Mitigation Plan credits was a result of an easement area decrease (0.04 acres) at
the top of DW1-A. The easement was offset 30 feet from the parcel line, however, during the
original survey an incorrect parcel line was used. This error was corrected in the recorded
easement but was never updated in the design files. Therefore, the length of DW1-A is now 15
linear feet (6 SMU) shorter in As-Built than what was shown in the Mitigation Plan, causing a
reduction in total credits from 4,161 SMUs to 4,155 SMUs. More details about project stream
lengths and credits are provided in Appendix A.

1.5 Stream Design/Approach

Stream restoration efforts along the tributaries of the Project were accomplished through analyses
of geomorphic conditions and watershed characteristics. The design approach applied a
combination of analytical and reference reach-based design methods that meet objectives
commensurate with both ecological and geomorphic improvements. Treatment activities ranged
from minor bank grading and planting to re-establishing stable planform and hydraulic geometry.
For full restoration reaches, natural design concepts were applied and verified through rigorous
engineering analyses and modeling. The objective of this approach was to design a
geomorphically stable channel that provides habitat improvements and ties into the existing
landscape. Specifically, treatments included Priority I and II stream restoration, Enhancement II,
and Enhancement III.

The Project has been broken into the following reaches:

Reach DW1-A - This reach begins on the southwest end of the Project, flows northeast to a
confluence with DW1-B and DW2-B, and totals 247 linear feet of Enhancement II. Open pasture
was located adjacent to the reach. Enhancement activities included improving habitat through
livestock exclusion fencing and riparian planting. The livestock exclusion fencing removed
livestock access to the riparian areas and provides wildlife corridors throughout the Project area.
A flow gauge was 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 1,948 linear feet of Priority I/II restoration. Managed pasture was
located adjacent to the reach on the upstream end. The downstream end was surrounded by
intermittently grazed pasture and disturbed secondary growth in an area with previous timber
harvest. Restoration activities included 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 were installed for stability and to improve habitat.
Habitat was further improved through buffer plantings and livestock exclusion. Buffer activities

Compass Point 6 Year 3 Monitoring Report
Mitigation Site September 2023
improve riparian areas that 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 I/II
restoration, beginning immediately downstream of a bedrock drop structure at the bottom of
DW1-B. Sections of the existing road were decommissioned in the easement and planted.
Restoration activities included 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 were installed for stability
and to improve habitat. Habitat was further improved through buffer plantings and livestock
exclusion. Livestock exclusion fencing removed livestock access to the riparian areas and provides
wildlife corridors throughout the Project area.
Reach DW1-D - This reach begins at the downstream end of DW1-C and culvert crossing in the
northern end of the Project, and flows northeast to DW1-E. The reach totals 758 linear feet of
Priority I/II restoration. Restoration activities included 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 was harvested and reused to create stable
bed features. In-stream structures such as log sills, brush toes, and log vanes were installed for
stability and to improve habitat. Habitat was further improved through buffer plantings and
livestock exclusion. Buffer activities improve riparian areas that 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 was located adjacent to the reach. Enhancement activities included improving habitat
through livestock exclusion fencing.
Reach DW2-A - This reach begins on the southeast end of the Project, and flows west to DW2-B.
This reach totals 760 linear feet of Enhancement II. Sparse woodland and managed pasture was
located adjacent to the reach. Enhancement activities included targeted bank stabilization,
riparian buffer planting, and installation of livestock exclusion fencing. An existing ford crossing
was removed. Buffer activities improve riparian areas that 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 485 linear feet of Priority I
Restoration. Actively managed pasture was present on both sides of the reach. Restoration
activities included constructing a new channel within the natural valley with appropriate
dimensions pattern and backfilling the abandoned channel. Native bed material was harvested
when possible. In-stream structures such as log sills, brush toes, and log vanes were installed for
stability and to improve habitat. Habitat was further improved through buffer plantings and
livestock exclusion. A crossing was installed along this reach. Buffer activities improve riparian

Compass Point 7 Year 3 Monitoring Report
Mitigation Site September 2023
areas that 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 II. Disturbed
woodland and intermittently grazed pasture was located adjacent to the reach. A maintained
powerline easement is located adjacent to the reach. Enhancement activities included improving
habitat through livestock exclusion fencing, and riparian buffer planting.
1.6 Construction and As-Built Conditions

Stream construction, planting, and fencing was completed in June 2020. The Project was closely
built to design plans and guidelines. One minor adjustment was made to the easement, causing
a total decrease of 0.04 acres. The easement was offset 30 feet from the parcel line, however,
during the original survey an incorrect parcel line was used. This change to the easement was
already corrected in the original recorded easement but was not updated in the original mitigation
plan. Therefore, the length of DW1-A is now 15 linear feet (6 SMUs) shorter in As-Built than what
was shown in the Mitigation Plan, causing a reduction in total credits from 4,161 SMUs to 4,155
SMUs. A few other minor changes were made to structures during construction which are detailed
in the redline version of the as-built survey in the As-Built Report (submitted August 2020). Project
credits are based on design centerline, but as-built stream lengths are also shown on Table 1.

Also, there were a few changes to the planting plan due to bareroot availability. Planting plan
changes are shown in Table 5.

1.7 Monitoring Performance (MY3)

Vegetation

Monitoring of the eight permanent vegetation plots and three random plots was completed
during August 2023. Vegetation data is in Appendix C, associated photos are in Appendix B, and
plot locations are in Appendix B. MY3 monitoring data indicates that 11 out of 11 plots are
exceeding the interim success criteria of 320 planted stems per acre. Planted stem densities
ranged from 324 to 1,052 planted stems per acre with a mean of 640 across all plots. A total of 19
species were documented within the plots. Volunteer species were noted in three of the plots. The
average stem height across all vegetation plots was 3.8 feet.

Current visual assessments of vegetation outside of the monitoring plots indicate that the
herbaceous vegetation is becoming well established throughout the project. The low stem density
area along DW2-A (Figure 2) will be supplemental planted this dormant season with
consideration for diversity (VPA1). Chinese privet and multiflora rose were successfully treated
across the site, mainly in existing wooded areas, in May 2023. No invasive problem areas are
reported in MY3.

Compass Point 8 Year 3 Monitoring Report
Mitigation Site September 2023
Stream Geomorphology

Geomorphology data for MY3 was collected during May 2023. Summary tables and cross section
plots are in Appendix D. While conditions have changed somewhat from As-built, cross section
data from MY3 is similar to that of MY1 and MY2. Changes in the first few years after restoration
activities are to be expected and MY3 data shows the stream is stabilizing as expected.

The channel is stable and transporting sediment as designed. Minor degradation was observed
on riffle Cross Section 12 which may be caused by the channel narrowing due to vegetation
growth. Additionally, in stream vegetation was observed on Cross Section 14. This is likely due to
the backwater from the Yadkin River depositing sediment in this lower reach. Two areas of bank
erosion were observed on DW1-C. The first (SPA1) is located near Cross Sections 11 and 12 and
the second (SPA2) is just below the bedrock outcrop. These banks will be repaired with additional
livestakes this dormant season.

Future monitoring events will continue to watch for aggradation and degradation. As requested
in the As-Built Credit Release Letter, RES has included a photo of the culverted crossing on DW1-
A in Appendix B. In MY3, there was water and substrate in all three of the culverts. RES will
continue to include photos of this crossing.

Stream Hydrology

In June 2020, one stage recorder was installed on restoration reach DW1-B to document bankfull
events and a flow gauge was installed on reach DW1-A to track the frequency and duration of
stream flow events. The site is on track to meet its hydrologic performance standards as evident
by eight bankfull events recorded over the past four years with two in 2023 and the DW1-A flow
gauge recording consecutive flow for 220 days in 2023. Stream hydrology data has been included
in Appendix E. The stage recorder and flow gauge locations can be found on Figure 2 and photos
are in Appendix B.

Wetland Hydrology

Three groundwater wells were installed in June 2020. The goal of the groundwater wells is to track
the hydrology in the jurisdictional wetlands on site post-construction. There is no hydroperiod
success criteria for these groundwater wells. GW1 and GW3 had 52 percent hydroperiod while
GW2 had a two percent hydroperiod. Data for this year is incomplete as the last collection event
occurred on August 9, 2023. It is expected that GW1 and GW3 will have a higher hydroperiod as
both wells last year showed a hydroperiod for 100% of the growing season. While GW2 had a low
hydroperiod within the growing season, hydroperiod outside of the growing season included 95
consecutive days or 26 percent of the year and there is wetland vegetation surrounding the well.
Wetland hydrology data has been included in Appendix E for GW1, GW2 and GW3. Groundwater
well locations can be found on Figure 2.

Compass Point 9 Year 3 Monitoring Report
Mitigation Site September 2023
2.0 Methods

Stream geomorphology monitoring was conducted using a Topcon GTS-312 Total Station. Three-
dimensional coordinates associated with cross-section data were collected in the field (NAD83
State Plane feet FIPS 3200). Morphological data were collected at 14 cross-sections. Survey data
were imported into CAD, ArcGIS®, and Microsoft Excel® for data processing and analysis.

Stream hydrology is monitored using stage recorders and flow gauges, which utilize automatic
pressure transducers, and were installed within the channels. The stage recorders record
frequency, duration, and stage of bankfull events and are programmed to record readings at an
hourly interval. A surveyed elevation was recorded at the bed and top of bank at the stage
recorder elevation, allowing for accurate bankfull events to be recorded. Flow gauges record
frequency, duration, and stage of flow events and are programmed to read at an hourly interval.
The height of the adjacent downstream riffle (from the gauge) is used to detect flow.

Vegetation success is being monitored at eight permanent monitoring plots and three random
plots for a total of 11 plots. Locations of random plots will vary from year to year and will be
shown in Figure 2, and species and height will be recorded for all woody stems. Vegetation plot
monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation, version 4.2 (Lee et al.
2008) and includes analysis of species composition and density of planted species. Data are
processed using the CVS data entry tool. In the field, the four corners of each plot were
permanently marked with PVC at the origin and metal conduit at the other corners. Photos of
each plot are taken from the origin each monitoring year.

Wetland hydrology is monitored to document maintenance of jurisdictional groundwater levels
in the stream restoration area (as requested by IRT). This is accomplished with three automatic
pressure transducer gauges (located in groundwater wells) that record daily groundwater levels.
One automatic pressure transducer is installed above ground for use as a barometric reference.
Gauges are downloaded quarterly and wetland hydroperiods are calculated during the growing
season. Gauge installation followed current regulatory guidance. Visual observations of primary
and secondary wetland hydrology indicators are also recorded during quarterly site visits.
