Wildlands Catawba 01 Umbrella Mitigation Bank— Double Rock Mitigation Site
Second Credit Release (Year 0/As-Built Completion)
Dear Mr. Kichefski:
This correspondence is in reference to the Double Rock Mitigation Site, part of the Wildlands Catawba 01
Umbrella Mitigation Bank. The 19.33-acre site is in the Lookout Shoals water supply watershed of the Upper
Catawba River Basin (03050101) and is located 6 miles southwest of Taylorsville in Alexander County, NC. The
purpose of this letter is to request the second release of credits (Baseline (Year 0) Monitoring Document and the
As -Built Report — Complete) for this mitigation site.
The Site construction was completed in April 2023, and the as -built survey was completed and finalized in May
of the same year. Post -construction planting was also completed in April 2023, as well as the installation of the
remainder of the monitoring components. The fence line installation and posting of the conservation easement
markers were completed by June 2023.
Minimal adjustments were made during construction and baseline profiles and cross-section dimensions closely
match the design parameters with little variation. Shortly after construction was complete, two areas of minor
bank erosion were noted during a site walk. One was on the left bank of Elk Shoals Creek at Station 126+55, and
the other was on the left bank of Randell Tributary at Station 211+65. These areas have since been restabilized
and are no longer of concern. Both areas are noted as red lines on the record drawings and discussed in Section
2 of the Baseline Report. Currently, all stream banks on the Site are stable and functioning as intended.
Monitoring year 0 (MYO) site assessments were conducted in April 2023. The Site's average planted stem density
was 634 stems per acre, which exceeds the interim vegetation criteria. A visual assessment and photo
documentation of the areas where populations of Hexastylis naniflora are located were conducted post -
construction, and none were disturbed. No areas of encroachment were noted, and the Site is performing well
and has met the required stream and vegetation success criteria for MYO. Wildlands will continue to assess the
Site for the required monitoring period.
With the successful completion of all initial physical and biological improvements as described in the site -specific
Double Rock Final Mitigation Plan dated June 2022, Wildlands is requesting the release of fifteen percent (15%)
of the Mitigation Site's total stream restoration, enhancement, and preservation credits or 669.690 stream

mitigation units (SMUs) to be available for sale. With this release, 30% of the total SMUs will have been
released. The Site's credit release schedule and credit ledger are included below.
Please contact us at 704-332-7754 if you have any questions.
Thank you,

Section 1: PROJECT OVERVIEW
Wildlands Holdings VI, LLC (Sponsor) developed the Double Rock Mitigation Site (Site) under the
Wildlands Catawba 01 Umbrella Mitigation Bank (Bank). Wildlands Holdings VI, LLC is managed by
Wildlands Engineering, Inc. (Wildlands) and was developed for the sole purpose of holding mitigation
banks.
The Site is located in Alexander County approximately six miles southeast of Taylorsville (Figure 1). The
project involves the restoration, enhancement, and preservation of Elk Shoals Creek and five unnamed
tributaries (Figure 3) and the implementation of one stormwater best management practice (BMP). The
project is located within the Elk Shoals Creek targeted local watershed (TLW) within the Lookout Shoals
Lake water supply watershed, classification WS-IV. The Site drains into the Catawba River, a 303d listed
stream approximately six miles downstream.
1.1 Project Quantities and Credits
The Site will provide stream mitigation credits in the Catawba 01 (HUC 03050101) (Figure 2). If the
official service areas of the Catawba River Basin are expanded/combined in the future, the service area
of this Site will automatically be expanded to include the expanded/combined service area. Mitigation
work within the Site included restoration, enhancement II, and preservation of perennial and
intermittent stream channels. Table 1 below shows stream credits by reach and the total amount of
stream credits expected at closeout.
The Site will also provide riparian buffer credits. The As -Built & Baseline Monitoring Report for the
Double Rock Buffer Mitigation Bank Parcel is submitted separately.
1.2 Project Goals and Objectives
The project is intended to provide numerous ecological benefits. Table 2 below describes expected
outcomes to water quality and ecological processes and provides project goals and objectives.
1.3 Project Attributes
The Site is comprised of two parcels. One is maintained as an active cattle farm, and the other is
currently wooded but has been managed for both timber and agriculture in the past. Historic aerial
photographs from 1950 to 2016 show that onsite streams have existed in their same approximate
location over 65 years, with limited changes to the agricultural management of the land. In 1983, the
agricultural fields along Elk Shoals Reach 1 decreased somewhat in size, and the remnant effects of
historic logging on the ridgelines of Matheson Tributary watershed were reforesting. Stikeleather Road
was straightened between the 1993 and 2006, but the Elk Shoals Creek and Stikeleather Creek Road
crossings remained in the same approximate locations.
This consistency in land use within the project watershed indicates that watershed processes affecting
hydrology, sediment supply, and nutrient and pollutant delivery have not varied widely over time.
Additionally, the Site is located in a rural watershed where the dominant land uses are agriculture,
forest, and silviculture. The land is zoned for low -density residential and agriculture purposes; therefore,
watershed processes and stressors from outside the project limits are likely to remain consistent
throughout the implementation, monitoring, and closeout of this project. Table 3 below and Table 8a-c
in Appendix C present additional information on the project attributes and pre -restoration conditions.

V/ As -Built & Baseline Monitoring Report

Section 2: As -Built Condition (Baseline)
The Site construction was completed in April 2023. The as -built survey was conducted from April
through May 2023 and finalized in June of the same year. The survey included developing an as -built
topographic surface, as well as surveying the as -built channel centerlines, top of banks, structures, cross -
sections, pressure transducers, and the fence line along Randell Tributary. The remainder of the
monitoring components were collected in April and June 2023, respectively, using an Arrow 100'
Submeter GNSS Receiver. Post -construction planting was also completed in April 2023. The installation
of the conservation easement markers was finalized in June 2023.

As -Built & Baseline Monitoring Report

Section 3: Monitoring Year 0 Data Assessment
Annual monitoring data will be reported in accordance with Regulatory Guidance Letter (RGL) 08-03.
The monitoring report shall provide project data chronology that will facilitate an understanding of
project status, trends, research purposes, and assist in decision making regarding close-out. The
monitoring period will extend seven years beyond completion of construction or until performance
criteria have been met. All survey data will be georeferenced to North Carolina State Plane coordinates.
Installed monitoring devices and plot locations closely mimic the locations of those proposed in the
Site's Mitigation Plan (Wildlands, 2022). Minor deviations from these locations were made when
professional judgement deemed them necessary to better represent as -built field conditions or when
installation of the device in the proposed location was not physically feasible.
Annual monitoring and site visits were conducted during MYO to assess the condition of the project. The
vegetation and stream success criteria for the Site follows the approved success criteria presented in the
Mitigation Plan (Wildlands, 2022). Performance criteria for vegetation, stream, and hydrologic
assessment are located in Section 1.2 Table 2: Goals, Performance Criteria, and Functional
Improvements. Monitoring reports will be prepared in the fall of each year and submitted to USACE no
later than April 1 of the following monitoring year. Monitoring features and locations are shown in
Figures 4.0 - 4.3.
3.1 Vegetative Assessment
The MYO vegetative survey was completed in April 2023. Vegetation monitoring resulted in a stem
density range of 526 to 728 planted stems per acre which is well above the interim requirement of 320
stems per acre required at MY3. Average stem density was 634 planted stems per acre. All 9 vegetation
plots met the interim success criteria and are on track to meet the final success criteria required for
MY7. Herbaceous vegetation is establishing itself across the site. As requested by the U.S. Fish and
Wildlife Service (USFWS), 11 photo points were established across the Site, prior to construction, for the
visual assessment of Hexastylis naniflora (HENA) populations during post -construction monitoring.
Photographs facing the North, East, South, and West were taken at each photo point in MYO and will be
subsequently taken in the same directions once each year for the seven year monitoring period. Figures
4.0 - 4.3 depict the locations of each HENA photo point and both permanent and mobile vegetation
plots. Refer to Appendix A for vegetation plot and HENA photographs, and Appendix B for vegetation
plot data.
3.2 Vegetation Areas of Concern
Vegetation management and herbicide applications were implemented during construction to prevent
the spread of invasive species that could compete with planted native species. The invasives along the
streams were mechanically removed during the grading of the new channels and floodplains.
Populations of Chinese privet (Ligustrum sinense) and multiflora rose throughout the existing site, and
lespedeza (Lespedeza cuneata) present along the northern Stikeleather Tributary boundary were
excavated during construction. Prior to construction, fescue within the conservation easement along Elk
Shoals Creek and Randell Tributary were treated with herbicide. Invasive species will continue to be
monitored, mapped, and controlled across the Site as necessary throughout the monitoring period. The
Vegetation Condition Assessment Table is included in Appendix A.
3.3 Stream Assessment
Morphological surveys for MYO were conducted in May 2023. All streams within the Site are stable and
functioning as designed. Compared to design, all 10 cross -sections at the Site show little to no deviation
WDouble Rock Mitigation Site Page 3-1
As -Built & Baseline Monitoring Report

in the bankfull area and width -to -depth ratio, and bank height ratios are less than 1.2. The tributaries
are designed to incise as they approach the main streams, so this would not be considered a trend
towards instability. Riffles may fine over the course of monitoring due to the stabilization of contributing
watershed sediment sources. Refer to Appendix A for the Visual Stream Morphology Stability
Assessment Table and Stream Photographs. Refer to Appendix C for Stream Geomorphology Data.
3.4 Stream Areas of Concern
Two areas of minor bank erosion were noted during a Site visit in early June. One area was on Elk Shoals
Creek at Station 126+55 - 126+60 and one on Randell Tributary at Station 211+65 - 211+80. Both areas
have since been repaired and are no longer of issue. See Section 2.1.3 and Section 2.1.4 for a description
of the repairs.
Currently there are no areas of encroachment on -site. Wildlands will continue to monitor the Site for
encroachment and/or instability throughout the monitoring period.
3.5 Hydrology Assessment
Crest gages (CG) were installed on Elk Shoals Creek Reach 1A, Elk Shoals Creek Reach 2, Randell
Tributary, and Stikeleather Tributary Reach 1A to monitor bankfull events. Since Stikeleather Tributary is
classified as a Rosgen B-type channel, where floodplain interaction is not an imperative function for
hydrologic measurement, the gage on this reach will also record continuous inner channel stream flow
throughout the monitoring period. Hydrologic data will be collected and reported during MY1.
3.6 Adaptive Management Plan
Site maintenance and adaptive measurement implementation will follow those outlined in the project's
Final Mitigation Plan (Wildlands, 2022). No adaptive management plans are needed at this time.
3.7 Monitoring Year 1 Summary
Overall, the Site looks good, is performing as intended, and is on track to meet success criteria. All
vegetation plots are on track to exceed the MY3 interim requirement of 320 planted stems per acre, and
all streams within the Site are stable and meeting project goals. Invasive species were treated before
and during construction and will continue to be assessed throughout the monitoring years.
Summary information and data related to the performance of various project and monitoring elements
can be found in the tables and figures in the report appendices.

As -Built & Baseline Monitoring Report

Section 4: METHODOLOGY
Annual monitoring will consist of collecting morphologic, vegetative, and hydrologic data to assess
project success based on the goals outlined in the Site's Mitigation Plan (Wildlands, 2022). Monitoring
requirements will follow guidelines outlined in the NC IRT Stream and Wetland Mitigation Guidance
Update (2016). Annual monitoring data will be reported in accordance with Regulatory Guidance Letter
(RG L) 08-03.
Geomorphic data was collected following the standards outlined in The Stream Channel Reference Site:
An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in Stream Restoration: A Natural
Channel Design Handbook (Doll et al., 2003). All Current Condition Mapping was collected by
either a professional licensed surveyor or an Arrow 100' Submeter GNSS Receiver and processed using
ArcPro. Crest gauges and pressure transducers were installed in riffle cross -sections and monitored
throughout the year. Vegetation monitoring protocols followed the Wilmington District Stream and
Wetland Compensatory Mitigation Update (NCIRT, 2016) and the Carolina Vegetation Survey-EEP Level 2
Protocol (Lee et al., 2008).

will ensure that surface water quality standards are met and conditions of waters are suitable for all
best uses.
10. Culverts shall be designed and installed in such a manner that the original stream profiles are not
altered and allow for aquatic life movement during low flows. The dimension, pattern, and profile of
the stream above and below a pipe or culvert shall not be modified by widening the stream channel or
by reducing the depth of the stream in connection with the construction activity. The width, height,
and gradient of a proposed culvert shall be such as to pass the average historical low flow and spring
flow without adversely altering flow velocity. If the width of the culvert is wider than the stream
channel, the culvert shall include multiple boxes/pipes, baffles, benches and/or sills to maintain the
natural width of the stream channel. If multiple culverts/pipes/barrels are used, low flows shall be
accommodated in one culvert/pipe and additional culverts/pipes shall be installed such that they
receive only flows above bankfull.
Placement of culverts and other structures in streams shall be below the elevation of the streambed
by one foot for all culverts with a diameter greater than 48 inches, and 20% of the culvert diameter for
culverts having a diameter less than or equal to 48 inches, to allow low flow passage of water and
aquatic life. If the culvert outlet is submerged within a pool or scour hole and designed to provide for
aquatic passage, then culvert burial into the streambed is not required.
For structures less than 72" in diameter/width, and topographic constraints indicate culvert slopes of
greater than 2.5% culvert burial is not required, provided that all alternative options for flattening the
slope have been investigated and aquatic life movement/connectivity has been provided when
possible (e.g. rock ladders, cross -vanes, sills, baffles etc.). Notification, including supporting
documentation to include a location map of the culvert, culvert profile drawings, and slope
calculations, shall be provided to DWR 30 calendar days prior to the installation of the culvert.
When bedrock is present in culvert locations, culvert burial is not required, provided that there is
sufficient documentation of the presence of bedrock. Notification, including supporting
documentation such as a location map of the culvert, geotechnical reports, photographs, etc. shall be
provided to DWR a minimum of 30 calendar days prior to the installation of the culvert. If bedrock is
discovered during construction, then DWR shall be notified by phone or email within 24 hours of
discovery.
Installation of culverts in wetlands shall ensure continuity of water movement and be designed to
adequately accommodate high water or flood conditions. When roadways, causeways, or other fill
projects are constructed across FEMA-designated floodways or wetlands, openings such as culverts or
bridges shall be provided to maintain the natural hydrology of the system as well as prevent
constriction of the floodway that may result in destabilization of streams or wetlands.
The establishment of native woody vegetation and other soft stream bank stabilization techniques
shall be used where practicable instead of rip -rap or other bank hardening methods.
