Double Rock Buffer Mitigation Bank Parcel
Catawba River Basin
Wildlands Holdings VI, LLC; Wildlands Catawba Umbrella Mitigation Banking Instrument
1.0 Introduction
The Double Rock Mitigation Bank Parcel ("Parcel") was created under the terms and conditions of the
Wildlands Catawba Umbrella Mitigation Banking Instrument (UMBI), made and entered into by
Wildlands Holdings VI, LLC acting as Bank Sponsor ("Sponsor") and the North Carolina Department of
Environmental Quality ("NCDE(X") Division of Water Resources ("NCDWR"). The Bank Parcel
Development Package (BPDP) was approved in September 2022. The Parcel has been planned,
designed, and constructed according to the UMBI and the Consolidated Buffer Mitigation Rule 15A
NCAC 02B .0295 which became effective November 1, 2015. The project has been designed in
concurrence with the Wildlands Catawba Umbrella Mitigation Bank, Double Rock Mitigation Site (DWR
ID#2020-1095v1). The service area is depicted in Figure 2.
The buffer mitigation project includes Elk Shoals Creek and two unnamed tributaries (Randall Tributary
and Stikeleather Tributary). The stream mitigation bank also includes three additional unnamed
tributaries (Matheson Tributary, Matheson Tributary A, and Matheson Tributary B), which are not
proposed for riparian buffer credit. Elk Shoals Creek eventually drains into the Catawba River, a 303(d)
listed stream, approximately 6-miles downstream. The primary purpose of the project is to provide
stream and riparian buffer mitigation credits to compensate for unavoidable impacts in the Catawba
River Basin Hydrologic Unit Code ("HUC") 03050101.
The Parcel creates a protected riparian area from top of bank out to 200 feet in some areas of the
project's buffer. The riparian buffer along the tributaries was restored to provide ecological and water
quality enhancements to the Catawba River Basin and create a functional riparian corridor. This project
protects 19.33 acres of riparian buffer by permanent conservation easement. On October 14, 2021,
NCDWR assessed the stream origin. The official Stream Origin Determination Letter was issued by
NCDWR on October 15, 2021. Subsequently, NCDWR conducted an onsite review of the project area to
determine viability for buffer mitigation and nutrient offset on December 7, 2021, and issued a site
viability letter on January 5, 2022. All three features assessed were deemed viable by NCDWR to
generate buffer mitigation. There have been no changes to land use in the project area since NCDWR's
2021 site visit. A copy of both the "On -Site Stream Origin Determination for Applicability to Catawba
Riparian Buffer Rules" and the "Site Viability for Buffer Mitigation" letters from NCDWR are included in
Appendix E. The conservation easement was recorded on the Parcel in October 2022.
2.0 Parcel Location & Background
2.1 Location and Setting
The Parcel is comprised of two parcels: one that is maintained as an active cattle farm, and one that is
currently wooded but has been managed for both timber and agriculture in the past. The Parcel is
located in Alexander County in the township of Hiddenite, approximately six miles southeast of
Taylorsville, NC (Figure 1). Directions are included on Figure 1. Though the Parcel was restored for
stream and riparian buffer mitigation credits in the Catawba River Basin HUC 03050101 (Figure 2), this
report is to document the implementation of the buffer mitigation efforts. The Parcel is located within
the Catawba River Basin HUC 03050101130010 (Elk Shoals Creek), NCDWR Subbasin 03-08-32, and the
Elk Shoals Creek Targeted Local Watershed (TLW) which amended is defined in the Catawba River Basin

Restoration Plan (NC-DEQ, 2018) as Water Supply IV Waters, which are used as a source of drinking
water, culinary, or food processing.
This project directly and indirectly addresses stressors identified in watershed planning documents by
excluding livestock, creating stable stream banks, restoring a forest in agriculturally maintained buffer
areas, and implementing stormwater BMPs. These actions will reduce fecal, nutrient, and sediment
inputs to Elk Shoal Creek and ultimately to Lookout Shoal Lake and the Catawba River, as well as
reconnect instream and terrestrial habitats on the site.
2. 2 Parcel Background
Prior to construction, much of the land within 200 feet from top of bank of the project features had
been cleared and maintained for active cattle pastures. Most of the streams were deeply incised. The
adjacent floodplains have maintained their rural, farming characteristics over the last 60 years with only
minor changes in landcover. Tables 2, 3, and 4 in Appendix A provide detailed information regarding the
project activity and reporting history, project contacts, and project information and attributes,
respectively.
2.3 Parcel Objectives
The major goals of the buffer mitigation project are to provide ecological and water quality
enhancements to the Catawba River Basin by restoring the riparian area to create a functional riparian
corridor. Specific enhancements to water quality and ecological processes are outlined below.

through restored native vegetation. The offsite nutrient input will also be
absorbed onsite by filtering flood flows through restored floodplain areas,
where flood flows can disperse through native vegetation.

uses.
3.0 Restoration Activities
Areas slated for riparian restoration that were not impacted by the construction of the stream
mitigation project required little site preparation. Select herbicide treatments and limited mechanical
clearing removed undesirable underbrush, invasive species, and fescue (Festuca spp.). The remaining
W Double Rock Mitigation Bank Parcel Page 2
As -Built & Baseline Monitoring Report

areas of the easement, within the construction corridor, were graded and management of undesirable
and invasive species were implemented in accordance with the IRT approved stream mitigation plan.
Compacted areas within the easement boundary, including haul roads and cattle -trampled areas, were
ripped prior to planting. The specifics of the stream restoration project, including the grading plan, were
included in the Double Rock Mitigation Plan (Wildlands, 2022). The post -construction implementation of
the stream restoration project was documented in the Double Rock Mitigation Site As -built and Baseline
Monitoring Report (Wildlands, 2023).
Developing the Parcel for buffer restoration required converting existing agriculture land use practices
adjacent to streams into riparian forest. The species composition was selected based on the desired
target community type (Piedmont Alluvial Forest, as defined by Schafale (2012)), the occurrence of
species in riparian areas adjacent to the Parcel, and best professional judgement. Trees and shrubs were
spaced at 6'X12' upon planting, which is equivalent to a stem density of 605 stems per acre and is
sufficient to meet the performance standards outlined in the Rule 15A NCAC 02B .0295 of 260 planted
trees and shrubs per acre at the end of five years. Table 6 in Appendix A lists the tree species and
quantities planted. There was no parcel preparation work done in the riparian preservation areas under
15A NCAC 02B .0295(o)(4) except as required in the stream mitigation plan (Wildlands, 2022).
The easement was marked using conservation easement placards mounted on t-posts following the
entirety of the boundary. These signs will be maintained and replaced, if necessary, throughout the
monitoring years.
4.0 Project Credit Potential and Deviations from the Bank Parcel Development Package (BPDP)
Of the 19.33 acres protected under the conservation easement, 6.17 acres were restored and 2.06 acres
were preserved for riparian buffer credit. The area of preservation credit within the buffer mitigation
site equals 25% of the total area of buffer mitigation. An additional 5.93 acres are used for crossings, for
the stream preservation areas on Matheson Trib, Matheson Trib A, and Matheson Trib B, and for the
buffer preservation areas which are greater than the 25% of the total credited area; these areas will not
receive credits. There is one credit ledger for the project: Riparian Buffer Credits. None of the riparian
buffer credits on the Parcel are convertible or transferable to nutrient offset credits.
The buffer mitigation credits will be derived from riparian areas adjacent to mitigated streams. Credit
calculations based on the as -built survey resulted in a slight reduction in the total credit area of
50,426.000 credits in the restoration area and 3,361.800 credits in the preservation area from what was
calculated for use in the BPDP. A map detailing the credit generation is provided in Figure 3. A copy of
the As -Built Buffer Map is included in Appendix F.
5.0 Monitoring Protocol & Success Criteria
Vegetation monitoring plots were installed and evaluated within the riparian restoration areas to
measure the survival of the planted trees and shrubs. A total of 6 (5 permanent and 1 mobile), 100-m2
plots were installed randomly throughout the planted, credited riparian buffer area (Figure 4). Five of
the vegetation plots, VP4, VPS, VP6, VP7, and MVP2, are also being used for vegetation monitoring in
the stream mitigation portion of the project. The permanent plots were established as either 10-meter
by 10-meter square plots or 5-meter by 20-meter rectangular plots, while mobile vegetation plots were
established as a 100-m2 circular, square, or rectangular plot. The mobile vegetation plot (MVP) will be
relocated in a different buffer restoration area in monitoring years 2, 3, and 5.
Vegetation assessments for permanent plots will be conducted and follow the Carolina Vegetation
Survey (CVS) Level 2 Protocol for Recording Vegetation (2008) while mobile vegetation plot assessments
will document number of stems, species, and height. A reference photo will be taken from the
W Double Rock Mitigation Bank Parcel Page 3
As -Built & Baseline Monitoring Report

southwestern corner, diagonally across each permanent vegetation plot, while photos for mobile
vegetation plots will be taken looking to the north. All planted stems will be marked with flagging tape
and recorded.
Annual monitoring activities will commence in the fall season of 2023. Vegetative assessments for
permanent vegetation plots will follow the Carolina Vegetation Survey (CVS) Level 2 Protocol for
Recording Vegetation (2008) and will document species composition, density, vigor, height, and survival
rates while mobile vegetation plot assessments will document stem density, species composition, and
stem height. The total number of volunteer woody stems will also be documented and reported. The
measure of vegetative success for the Parcel will be the survival of at least four native hardwood tree
species, where no one species is greater than 50% of the established planted stems, and an established
density of at least 260 planted trees and shrubs per acre at the end of the fifth year of monitoring.
Appropriate and desirable native volunteer species may be included in the Parcel's density to meet the
performance standards with written NCDWR approval. The Sponsor shall submit the annual monitoring
report to NCDWR by December 315Y of each year for five consecutive years and will follow the terms and
conditions of the approved BPDP (Wildlands, 2022).
A visual assessment of the conservation easement will also be performed and reported in the annual
monitoring reports each year to NCDWR to confirm:
• Existing fencing is in good condition throughout the site;
• No cattle access within the conservation easement area;
• No encroachment has occurred;
• Diffuse flow is being maintained in the conservation easement area;
• There has not been any cutting, clearing, filling, grading, or similar activities that would
negatively affect the functioning of the buffer; and
• Easement boundaries are clearly and distinctly identified by marker, post, tree -blazing, or other
means as allowed.
Boundary markers that have been disturbed, damaged, or destroyed will be repaired and/or replaced on
an as needed basis. Contact information for the conservation easement holder will me included on the
easement markers.
Baseline data shows a planted stem density range of 526 to 688 planted stems per acre with an average
of 621 planted stems per acre across the project area; thereby exceeding the requirement of 260 stems
per acre at the end of the five year monitoring period (Table 7). At least four native hardwood tree
species were present in each vegetation plot with no one species equaling greater than 50% of the
planted stems. All 6 vegetation plots are expected to meet the final success criteria required for MY5.
A visual site assessment was conducted on 4/25/2023. During the assessment, no cattle nor evidence of
cattle encroachment were found within the easement. The fence was in good condition. There was no
evidence of mowing, cutting, clearing, or grading of the buffer, and diffuse flow was being maintained
across the easement.
6.0 Financial Assurance & Long -Term Management
6.1 Financial Assurance
After completion of the restoration/construction, a separate Performance/Maintenance Bond will be
secured for 100% of the estimated cost to implement the monitoring and maintenance plan, but not less
than $100,000.00. The Performance/Maintenance Bond shall apply at the inception of the monitoring
period for a term of one year, to be extended annually for a minimum of five years. Upon NCDWR
approval, this may be lowered each year based on the adjusted cost to complete the monitoring.
W Double Rock Mitigation Bank Parcel Page 4
As -Built & Baseline Monitoring Report

Performance bonds for monitoring shall be renewed at least annually to cover the next years monitoring
period, with confirmation of renewal provided to NCDWR with each annual monitoring report when
applicable. NCDWR reserves the right to alter the credit release schedule if monitoring reports are
submitted without proof of bond renewals when applicable.
6.2 Parcel Maintenance
Adaptive measures will be developed, or appropriate remedial actions will be implemented if the Parcel
or a specific component of the Parcel fails to achieve the success criteria. Parcel maintenance will be
performed to correct any identified problems that have a high likelihood of affecting project success.
Such items include, but are not limited to, fire, flooding, drought, or insects that cause excess tree
mortality. Any actions implemented will be designed to achieve the success criteria and will include a
work schedule and updated monitoring criteria. Any Parcel maintenance performed will be included in
the monitoring report for that year. A rigorous herbicide schedule may be implemented in the first few
years of tree establishment in the restoration areas to prevent establishment of invasive and/or
undesirable species that may out -compete native vegetation. The only herbicides used on the Parcel will
be aquatic approved herbicides that will be applied in accordance with North Carolina Department of
Agriculture rules and regulations.
As previously discussed in Section 5.0, the easement boundary will be checked annually as part of
monitoring activities. Easement boundary conditions as well as any maintenance performed will be
reported in the annual monitoring reports to NCDWR.
6.3 Long-term Management
The Parcel will remain in private ownership, protected in its entirety by Unique Places to Save, an
approved NCDWR long term stewardship, and will be managed under the terms detailed in an approved
NCDWR conservation easement. The long-term manager will be responsible for periodic inspection of
the Parcel to ensure that the restrictions documented in the recorded easement are upheld in
perpetuity.
