1 Project Summary
1.1 Project Location and Description
The Horne Creek Tributaries Mitigation Project (“Project”) is a North Carolina Department of
Environmental Quality (NCDEQ), Division of Mitigation Services (DMS) full-delivery mitigation project
contracted with Water & Land Solutions, LLC (WLS) in response to RFP 16-006993. The Project
construction and planting was completed in April 2020. The Project was built as documented in the
approved mitigation plan and record drawings. The Project provides warm stream mitigation credits in
the Yadkin River Basin (Cataloging Unit 03040101). The Project is located in Surry County
approximately seven miles southwest of the Town of Pilot Mountain (36.282582°, -80.509153°).
The Project restored, enhanced, and permanently protected seven stream reaches (R1, R2, R3, R4, R4a,
R4b, and R5) and their riparian buffers, totaling approximately 5,428 linear feet of stream channel. The
Project provides significant ecological improvements and functional uplift through stream and aquatic
habitat restoration and through decreasing nutrient and sediment loads within the watershed. The
mitigation plan provides a detailed project summary and Table 1 provides a summary of project assets.
Monitoring Year 4 (MY4) activities occurred in April and October 2023. This report presents the data for
MY4. The Project meets the MY4 success criteria for stream hydrology, stream horizontal and vertical
stability, streambed condition and stability, and stream flow. All three flow gauges met the 30-day
consecutive flow criteria. Both crest gauges recorded bankfull events. Based on these results, the Project
is on trajectory to meet interim and final success criteria. For more information on the chronology of the
project history and activity, refer to Appendix A, Table 2. Relevant project contact information is
presented in Appendix A, Table 3 and project background information is presented in Appendix A, Table
4.
1.2 Project Goals and Objectives
The Project is on track to meet the goals and objectives described in the Horne Creek Tributaries Final
Approved Mitigation Plan and will address general restoration goals and opportunities outlined in the
North Carolina Division of Mitigation Services (DMS) Upper Yadkin River Basin Restoration Priority Plan
(RBRP) (DEQ 2009). More specifically, watershed goals and management strategies described in the Upper
Yadkin Local Watershed Plan (LWP) will be met by:
• Reducing sediment, soil erosion, turbidity, and nutrient inputs such as fecal coliform bacteria,
nitrogen, and phosphorus to the Horne Creek Watershed.
• Restoring, enhancing, and protecting headwater streams, wetlands, riparian buffers, and aquatic
habitat functions.
• Improving riparian corridor management and targeting restoration of impacted streams and
riparian buffer areas.
• Promoting agronomic farm management techniques and implementing agricultural BMPs and
water quality features such as livestock exclusion fencing, alternative watering systems, and
nutrient management devices.
To accomplish these project-specific goals, the following objectives will be measured to document overall
project success:

MY4 FINAL Horne Creek Tributaries
DMS Project ID #100026

• Provide a floodplain connection to the incised Project stream reaches by lowering bank height
ratios (BHRs) to less than 1.2, thereby promoting more natural or overbank flood flows,
• Improve bedform diversity by increasing scour pool spacing and depth variability,
• Increase native species riparian buffer and vegetation density/composition along streambank and
floodplain areas that meet requirements of a minimum 30-foot-wide and 210 stems/acre
composition after the monitoring period,
• Improve aquatic habitat and fish species diversity and migration through the addition of in-stream
cover and native woody debris,
• Site protection through an 11.87-acre conservation easement in excess of 30 feet from the top of
the restored streambanks that will protect all streams, wetlands, and aquatic resources in
perpetuity.
1.3 Project Success Criteria
The success criteria for the Project follows the approved performance standards and monitoring protocols
from the final approved mitigation plan, which was developed in compliance with the USACE October
2016 Guidance, USACE Stream Mitigation Guidelines (April 2003 and October 2005), and 2008
Compensatory Mitigation Final Rule. Cross-section and vegetation plot data will be collected in Years 0, 1,
2, 3, 5, and 7. Stream hydrology data and visual monitoring will be reported annually. Specific success
criteria components and evaluation methods are described below.
1.3.1 Streams
Stream Hydrology: Four separate bankfull or over bank events must be documented within the seven-
year monitoring period and the stream hydrology monitoring will continue until four bankfull events have
been documented in separate years. Stream hydrology monitoring will be accomplished with pressure
transducers installed in pools and correlating sensor depth to top of bank elevation (Figure 4). Recorded
water depth above the top of bank elevation will document a bankfull event.
Stream Profiles, Vertical Stability, and Floodplain Access: Stream profiles, as a measure of vertical
stability and floodplain access, will be evaluated by looking at Bank Height Ratios (BHR). In addition,
observed bedforms should be consistent with those observed for channels of the design stream type(s).
The BHR shall not exceed 1.2 along the restored Project stream reaches. This standard only applies to
restored reaches of the channel where BHRs were corrected through design and construction. Vertical
stability will be evaluated with visual assessment, cross-sections and, if directed by the IRT, longitudinal
profile.
Stream Horizontal Stability: Cross-sections will be used to evaluate horizontal stream stability on restored
streams. There should be little change expected from as-built restoration cross-sections. If measurable
changes do occur, they should be evaluated to determine if the changes represent a movement toward a
more unstable condition (e.g., downcutting, erosion) or a movement towards increased stability (e.g.,
settling, vegetation establishment, deposition along the streambanks, 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.

Streambed Material Condition and Stability: Pebble counts or streambed material samples will not be
collected per the DMS Pebble Count Data Requirements memo sent on October 19, 2021. The IRT reserves
the right to request pebble count data/particle distributions if deemed necessary during the monitoring
period.
Jurisdictional Stream Flow: Monitoring of stream flow will be conducted to demonstrate that the restored
stream systems classified as intermittent exhibit surface flow for a minimum of 30 consecutive days
throughout some portion of the year during years with normal or below normal rainfall conditions. Stream
flow monitoring will be accomplished with pressure transducers installed in pools and correlating sensor
depth to the downstream top of riffle elevation (diagram in Appendix D). If the pool water depth is at or
above the top of riffle elevation, then the channel will be assumed to have surface flow.
1.3.2 Vegetation
Vegetation monitoring will occur in the fall each required monitoring year, typically prior to leaf drop.
Plots will be monitored in years 0, 1, 2, 3, 5, and 7. Vegetative success for the Project during the
intermediate monitoring years will be based on the survival of at least 320, three-year-old trees per acre
at the end of Year 3 of the monitoring period; and at least 260, five-year-old trees per acre that must
average six feet in height at the end of Year 5 of the monitoring period. The final vegetative restoration
success criteria will be achieving a density of no less than 210, seven-year-old stems per acre that must
average eight feet in height in Year 7 of monitoring. Volunteer species on the approved planting list that
meet success criteria standards will be counted towards success criteria.
1.3.3 Visual Assessment
WLS will conduct visual assessments in support of mitigation performance monitoring. Visual assessments
of all stream reaches will be conducted twice per monitoring year with at least five months in between
each site visit for each of the seven years of monitoring. Photographs will be used to visually document
system performance and any areas of concern related to streambank and bed stability, condition of in-
stream structures, channel migration, active headcuts, live stake mortality, invasive plant species or
animal browsing, easement boundary encroachments, cattle exclusion fence damage, and general
streambed conditions. Permanent photo points will be located at cross-sections, culvert crossings, and
Enhancement II reaches.

3 Monitoring Year 4 Assessment and Results
The dates of Year 4 monitoring activities are detailed in Appendix A, Table 2. All Year 4 monitoring data is
presented in this report and in the appendices. The Project is on track for meeting stream interim success
criteria. No cross-section or vegetation plot data was collected during MY4 monitoring. Visual assessments
of stream stability and vegetation condition were performed in the spring and fall site visits. All monitoring
device locations are depicted on the CCPV (Figure 1).
3.1 Morphological Assessment
3.1.1 Stream Horizontal Pattern & Longitudinal Profile
Visual assessment was utilized for assessment of MY4 horizontal and vertical stream stability. The visual
assessments for each stream reach concluded that the MY4 stream channel pattern and longitudinal
profiles, and in-stream structure location/function, still closely match the profile design parameters and
MY0/baseline conditions (Appendix C). The MY4 planform geometry and dimensions fall within acceptable
ranges of the design parameters for all restored reaches. Minor channel adjustments in riffle slopes, pool
depths and pattern were observed based on natural sediment migration and stream bank vegetation
establishment but did not present a stability concern or indicate a need for remedial action.

During the fall visual assessment for MY1, WLS staff noted seven potential problem areas outside the
channel. One additional in-channel problem area was noted during MY2. Problem areas 1-4, 6, and 7 from
MY2 have all been stabilized and are no longer considered problem areas. The remaining areas are noted
on the CCPV (Figures 1a-1c) and photos can be found in Appendix B and the E-Data Submission included
with this report. No additional problem areas were identified during MY4.
• SPA5- On R5, in the left floodplain area: minor deposition and erosion is occurring adjacent to
station 32+60 because of erosion outside of the easement.
o MY3 Action: No action was taken during MY3.
o MY4 Action: Grading activities outside of the conservation easement stabilized the
erosion occurring in the pasture. The work was completed using a small excavator in July
2023. Matting and coir wattles were installed to stabilize soil and slow water flow. The
area was seeded and mulched. Only minor hand work was completed within the
easement to add seed to areas of sediment deposition. Herbaceous cover is establishing
well within the easement and no additional erosion was observed outside the easement.
WLS will continue to monitor the repair during MY5.
• SPA8- On R4, just below two log vanes from approximate station 20+75 to 21+75, an area of the
stream has dropped elevation due to migrating riffle material causing stream incision. Coarse riffle
substrate is still present, the log vanes directly upstream are stable and functional, and the culvert
immediately downstream is holding grade. No additional incision was observed in MY4, and no
remedial action is required. This area will continue to be monitored closely in MY5. Cross-section
data will be completed again in MY5, and the area will be removed from the problem area list if
it is stable.
3.1.2 Stream Horizontal Dimension
Cross-section surveys were not required for MY4 per the mitigation plan. They will be completed in MY5.
Visual surveys indicate the project reaches are functioning as designed and stable. WLS will closely
monitor any changes to stream reaches during MY5.
3.2 Stream Hydrology
3.2.1 Stream Flow
Two flow gauges (FG-1 and FG-3), installed in May 2020 on R1 and R4 respectively, documented that the
stream exhibited surface flow for a minimum of 30 consecutive days throughout MY4 (Appendix D). One
additional flow gauge (FG-2) was installed during MY1 further upstream on Reach R2 on September 18th,
2020 in response to IRT comments received during the September 15th, 2020 site visit. FG-2 met the 30-
day flow requirement in MY4, recording a maximum flow duration of 37 days. The riffle was resurveyed
in MY4 to determine downstream riffle elevations. The flow depth was adjusted from 1.00’ to 0.98’. This
adjusted riffle elevation changed the early season flow duration to 37 days. Additionally, to determine if
rainfall amounts are normal for the given year, precipitation data was obtained from Pilot Mountain
Weather Station (CBTN7), approximately five miles north of the site. Rainfall was above normal for 2023
(Appendix D).

3.2.2 Bankfull Events
During MY4, bankfull events were recorded on both pressure transducer and crest gauges. CG-1 (R1)
recorded fifteen events with a maximum event of 0.67’ above bankfull. CG-2 (R5) recorded seven events
with a maximum event of 0.85’ above bankfull. Additionally, the cork crest gauge located adjacent to CG-
1 on R1 recorded one bankfull event. The associated data and photographs are located in Appendix D.
3.3 Vegetation
Vegetation plot surveys were not required during MY4 per the mitigation plan; surveys will continue in
MY5. The MY4 vegetation monitoring was conducted utilizing visual assessment throughout the
easement. Visual assessment of vegetation outside of the monitoring plots indicates that planted stems
and the herbaceous vegetation is becoming well established throughout the project.

A small cluster (below the mapping threshold) of princess tree (Paulownia tomentosa) is located on the
right-side slope of R4 and is actively being cut-stump treated with herbicide. No other areas of significant
invasive plant species were observed during monitoring year 4. The site will be monitored closely, and any
invasive plant species will be treated as needed. Small populations of narrow-leaved cattail (Typha
latifolia) are present in some saturated floodplain areas; however, none were observed causing issues
within the channels or affecting planted trees.

4 Methods
The stage recorders include an automatic pressure transducer (HOBO Water Level (13 ft) Logger) set in
PVC piping in the channel. The elevation of the bed and top of bank at each stage recorder location was
recorded to be able to document presence of water in the channel and out of bank events. Visual
observations (i.e. wrack or debris lines) and traditional cork crest gauges will also be used to document
out of bank events.
Vegetation success is being monitored at a total of 10 permanent vegetation plots. Vegetation plot
monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation, version 4.2 (Lee et al. 2008)

MY4 FINAL Horne Creek Tributaries

and includes analysis of species composition and density of planted and volunteer 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 rebar at the other corners. Tree species and height will be recorded for
each planted stem, and photos of each plot are to be taken from the origin each monitoring year.
Vegetation plot monitoring did not occur in MY4 and will continue in MY5.
Benthic macroinvertebrate (BMI) sampling used methods and procedures defined by DWR’s Standard
Operating Procedures for the Collection and Analysis of Benthic Macroinvertebrates (NCDWR, 2016) to
determine a Biotic Index (BI) value and a bioclassification rating. Sampling was conducted during MY3 and
will be conducted again in MY7.
