DMS Project No. 100078
June 25th, 2020
1.0 Mitigation Project Summary
The Longhorn Riparian Buffer Restoration Project (“the Site”) is a buffer restoration project located in
Randolph County, approximately 1.5 miles northwest of the Town of Sophia, North Carolina and
approximately 9 miles south of High Point (NC). The property is situated just east of NC Highway 311 and
is bounded to the south by Marlboro Church Road (refer to Figure 1). The Longhorn Buffer Mitigation Site
is located within the Muddy Creek 12-digit HUC (030300030106) of the Randleman Lake watershed (Figure
2). The buffer restoration and enhancement areas are located along an unnamed tributary (UT) of Bob
Branch and drainages that flow directly into Randleman Lake Reservoir approximately 2 river miles
downstream (refer to Figure 3 and Figure 4). Prior to project completion, the Site was surrounded by areas
managed for cattle production and lacked existing forested buffer along a majority of the streams and
pond dissecting the site. The Site is expected to generate 376,644.994 riparian buffer credits (BMU).
The Site is located within Hydologic Unit Code (HUC) 030300003010060 and North Carolina Department
of Water Resources (NC DWR) Sub-Basin 03-04-07. The buffer mitigation site consists of one stream reach
(A1) and an in-line pond (P1) as illustrated in Figure 8. Reach A1 is a perennial stream that flows from the
in-line pond (P1) to the north and into Bob Branch approximately 1,300 lf downstream. Bob Branch has a
NC DEQ surface water classification as a WS-IV* waterbody.
1.1 Project Goals
The main goals of the project are to provide high quality compensatory mitigation for authorized riparian
buffer impacts credited through the NC DMS in-lieu-fee program and occurring within the Randleman
Lake Watershed by creating a riparian corridor and restoring the historic riparian buffer. The project
addresses the watershed goals identified in the Cape Fear River Basin Restoration Plan (RBRP) (NC EEP,
2010). These goals include:
● Removal of non-point source pollution (including nitrogen, phosphorous, and fecal bacteria)
resulting from current land-use practices (principally cattle pasture);
● Reduction of sediment run-off/sediment loading to creek waters resulting from cattle hoof
shear, bank instability, and lack of riparian buffer woody vegetation;
● Increased floodwater attenuation;
● Enhancement and protection of stream ecology and aquatic/semi-aquatic habitats; and
● Enhancement and protection of terrestrial habitats along stream terraces and hillside slopes.
These goals will be achieved via the restoration and protection of riparian buffers and adjacent riparian
areas along an unnamed tributary of Bob Branch (which flows east into Randleman Lake Reservoir).
Specific objectives of the proposed project to achieve the desired goals include:
● Conversion of existing cattle pasture into wooded riparian buffer and wooded riparian areas
along the existing stream channel and pond via planting of characteristic hardwood species and
installation of cattle-exclusion fencing;
● Reduction of stream bank instability via woody stem plantings (i.e. increased woody root
material) and cattle exclusion fencing;
Longhorn Riparian Buffer Mitigation Site – Baseline and As-Built Monitoring Report 2 | Page
DMS Project No. 100078
June 25th, 2020
● Ensuring diffuse flow and increased surface roughness throughout the buffer mitigation area;
● Establishment of a conservation easement to protect the riparian buffer restoration site in
perpetuity; and
● Invasive species management (as needed) during monitoring period.
Ancillary benefits of the proposed riparian buffer and adjacent riparian area restoration effort include:
• Increase of organic material as food for invertebrate, fish and wildlife;
• Supply of woody debris that provides increased niche habitat for fish, invertebrates and
amphibians;
• Reduction of sunlight reaching the stream and modulation of surface water temperatures; and
• Floodwater attenuation via temporary storage, interception and slow releases from heavy rains.
1.2 Pre-construction Site Conditions
The project includes 20.81 acres of mostly open cattle pasture with one stream reach (A1) and an in-line
pond (P1) which drains to Bob Branch. An additional 0.89-acres was added to the project area to include
the pond dam within the conservation easement and will be reflected in an amendment to the
Conservation Easement Plat. The Site has historically been managed for agricultural and cattle production.
Site drainage and hydrology have been historically altered via the impoundment of waters. Based upon
a review of available aerial photography, the tributary was impounded in the early 1970s (between 1970
and 1973). A portion of the site was in cropland as early as 1948. The remaining land was cleared and
converted to agricultural production in the 1950s.
The buffer mitigation site consists of one stream reach (A1) and an in-line pond (P1) as illustrated in Figure
8. Reach A1 is a perennial stream that flows from the in-line pond (P1) to the north and into Bob Branch.
There is approximately 625 lf of stream associated with Reach A1 within the proposed buffer easement
area. Pond (P1) is an in-line pond that is approximately 5.3-acres and lies entirely within the proposed
conservation easement area.
The stream reach (A1) and an in-line pond (P1) have been restored as a forested riparian buffer to 200-ft
(approximately 12.73 acres) while approximately 0.40 acres of partially forested areas are considered
suitable for buffer enhancement. An additional 0.21 acres of existing, wooded riparian area will be
enhanced as cattle exclusion fencing will be installed around the conservation easement boundary. As
indicated above, an amendment to the Conservation Easement Plat to include the pond dam will be
provided to NCDMS and NCDWR following recordation. The project attributes are listed in Table 1, located
in Appendix A.
2.0 Determination of Credits
On June 19th, 2019, Ms. Katie Merritt of the Division of Water Resources (DWR) performed an
evaluation of surface water features and adjacent riparian areas within the proposed mitigation
site for the determination of riparian buffer mitigation pursuant to 15A NCAC 02B .0295
Longhorn Riparian Buffer Mitigation Site – Baseline and As-Built Monitoring Report 3 | Page
DMS Project No. 100078
June 25th, 2020
(effective November 1, 2015). Based upon this evaluation, DWR determined that areas within
200 ft of Reach A-1 and Pond P-1 are eligible for buffer credit. Inclusive of this area are
approximately 12.73 acres of non-forested restoration site per 15A NCAC 02B 0.0295 (n). In
addition, 0.40 acres of partially forested areas are considered suitable for buffer enhancement per 15A
NCAC 02B 0.0295 (n) (i.e. areas classified such that the establishment of woody stems (i.e., tree or shrub
species) will maximize nutrient removal and other buffer functions).
In addition to buffer restoration and enhancement on subject streams, per the Consolidated Buffer
Mitigation Rules (15 A NCAC 02B 0.0295 (o)), alternative mitigation is proposed on the site in the form of:
1) enhancement of grazing areas adjacent to streams. The project is in compliance with these rules as it
meets the following criteria:
Enhancement of Grazing Areas Adjacent to Streams (15A NCAC 02B 0.0295 (o)(6)):
Buffer credit at a 2:1 ratio shall be available for an applicant or mitigation provider who proposes
permanent exclusion of grazing livestock that otherwise degrade the stream and riparian zone through
trampling, grazing, or waste deposition by fencing the livestock out of the stream and its adjacent buffer.
An additional 0.21 acres of existing, wooded riparian area will be enhanced as cattle exclusion fencing will
be installed around the conservation easement boundary.
There are no known site constraints that would impede or adversely affect the restoration, enhancement,
and preservation of riparian buffer within the recorded easement area. Diffuse flow of runoff will be
maintained in the riparian buffer.
Mitigation credits are presented in Table 2 and Figure 8 in Appendix A and are based upon the
conservation easement survey.
3.0 Baseline Summary
The project team restored high quality riparian buffers along all unnamed tributaries and an in-line pond
within the Site. The project design ensured that no adverse impacts to wetlands of existing riparian buffers
occurred during implementation. Refer to Figure 8 for the conceptual design of the project. Details of the
restoration activity that occurred follows in the sections below.
3.1 Planting Preparation
Based upon pre-project assessment of compaction within the proposed planting areas, all areas targeted
for vegetative plantings within the buffer restoration project were ripped to reduce compaction and to
enhance microtopography. Spot spraying of herbicide was initiated for control of invasive species within
the restoration, enhancement and preservation areas (i.e. Chinese privet (Ligustrum sinense), Multiflora
rose (Rosa multiflora, Japanese honeysuckle (Lonicera japonica), and Chinese tree-of-heaven (Ailanthus
altissima)). Treatment areas are depicted on Figure 9. The existing 84-ft pond spillway was stabilized prior
to planting. The spillway was widened to approximately 10-feet and tapered down to 6-feet. The side

DMS Project No. 100078
June 25th, 2020
slopes were lined with coir fiber matting, and the bottom of the spillway lined with rip-rap. Appropriate
erosion control measures were implemented before, during, and after the spillway maintenance to
prevent sediment loss into downstream waters. No other site preparation occurred. No observed drain
tiles were observed prior to, or during, construction and planting and no other land disturbance was
needed to maintain diffuse flow as required.
3.2 Riparian Area Restoration and Enhancement Activities
The conservation easement boundary was marked using 6-inch diameter treated post buried 2 feet,
standing 5 feet above the ground surface, within the pasture. Woven wire fencing with a top strand of
barbed wire was installed along the entire easement boundary. One pedestrian access gate was installed
for future monitoring and access. Three 12-ft wide gates were installed in appropriate locations to allow
cattle to exit in case they were to breach the fence and enter the conservation easement. The easement
boundary was marked with standard yellow Conservation Area signs, per the 01/23/14 NCDMS Boundary
Marking Standards.
The planting plan consisted of the planting at least four hardwood species on a density of approximately
538 stems per acre. Species selection and distribution were matched closely to micro-site hydrologic and
edaphic conditions and include species characteristic of riparian assemblages in the watershed. In other
words, species more tolerant of poorly drained soils (i.e. river birch, green ash, and willow oak) were
planted within lower landscape positions generally consisting of the Chewacla and Wedhakee soil series
while species characteristically occurring in better drained soils (Wynott-Enon complex) will be planted in
higher landscape positions (i.e. hillside slopes). The selected native trees are well-suited to the site-specific
conditions of the property to promote high survivorship rates. No one tree species planted was greater
than 50% of the established stems. Site planting was conducted on April 1st, 2020 by Carolina Silvics, Inc.
and supervised by project managers from both Clearwater Mitigation Solutions and Land Management
Group.
Table 3 summarizes the planting plan for the Longhorn mitigation site.

4.0 Baseline Monitoring and Performance Criteria
Annual Monitoring will be conducted during the growing season for a period of five years. The report will
include all information required by DMS monitoring guidelines including photographs, plot locations, and
documentation of existing species density and composition. Monitoring will be performed in accordance
with the Consolidated Mitigation Buffer Rule (15A NCAC 02B .0295) and current DMS standards. The
performance criteria for the Site follows approved performance criteria presented in the guidance
documents outlined in the Consolidated Buffer Rule (15A NCAC 02B .0295). Performance criteria will be
evaluated throughout the five-year post-construction monitoring.
4.1 Vegetation
The final vegetative success criteria will be the survival of 260 planted stems per acre in the riparian buffer
at the end of the required monitoring period (Monitoring Year (MY) 5). Vegetative monitoring included
the establishment of eleven (11) permanent plots consistent with the Carolina Vegetation Survey (CVS)
protocol Level 2 (version 4.2) (refer to Figure 9 for plot locations). Reference photos of the vegetation
plots and Site were taken at each predetermined photo point location. Appendix B includes the baseline
(MY0) vegetation plot photographs and the planted and total stem counts (Table 4). Any vegetative
problem areas in the site will be noted and reported in each monitoring report. Vegetative problem areas
may include areas that either lack vegetation or include populations of exotic vegetation. Monitoring
reports will identify any contingency measures that may need to be employed to remedy site deficiencies.
4.2 Photo Reference Stations
Permanent photo stations were established across the project area in order to document site stability for
five years post construction. Markers were established and located with GPS equipment so that the same
locations and view directions on the Site are photographed each year. Photo reference stations are shown
on Figure 9 and photos are included in Appendix B.
4.3 Visual Assessments
Visual assessments will be performed annually during the five-year monitoring period. Problem areas of
vegetative health will be noted and areas of concern will be mapped, photographed, and documented in
the subsequent annual monitoring report. Problem areas that are found will be re-evaluated in each
subsequent monitoring event.
4.4 Annual Reporting Of Performance Criteria
Monitoring reports will be prepared in the fall of each monitoring year utilizing the NCDMS Riparian Buffer
and Nutrient Offset Buffer Baseline and Annual Monitoring Report Template (ver. 2.0) (May 2017).
Monitoring reports will be submitted to NCDMS by December 31st of the current monitoring year. The
monitoring period will occur five years post-construction or until the performance criteria have been met.

DMS Project No. 100078
June 25th, 2020
4.5 Maintenance and Contingency Plans
Any problem areas in the Site will be noted and reported in each monitoring report. Vegetative problem
areas may include areas that either lack vegetation or include populations of exotic vegetation.
Monitoring reports will identify any contingency measures that may need to be employed to remedy site
deficiencies. For instance, invasive vegetation management may be needed if exotic species volunteer
into the site. If it is determined that the Site’s ability to achieve the performance standards are
jeopardized, staff members of NCDMS/NCDWR will be notified and an adaptive management plan will be
developed to address these issues.
