Honey Mill Mitigation Site
Monitoring Year 3 Annual Report – FINAL iii
EXECUTIVE SUMMARY
Wildlands Engineering, Inc. (Wildlands) implemented a full-delivery stream mitigation project at the
Honey Mill Mitigation Site (Site) for the North Carolina Department of Environmental Quality (DEQ)
Division of Mitigation Services (DMS). The project restored and enhanced a total of 8,683 linear feet
(LF) of perennial and intermittent stream in Surry County, NC. The Site is located within the Rutledge,
Stoney and Flat Shoal Creek – Ararat River targeted local watershed (TWL) and NC Division of Water
Resources (DWR) Subbasin 03-07-03. The project is providing 4,793.432 cool stream mitigation units
(SMUs) for the Yadkin River Basin Hydrologic Unit Code (HUC) 03040101110020.
The Site’s immediate drainage area and the surrounding watershed have a long history of agricultural
activity. The project excludes livestock, creates stable stream banks, converts pasture to forest, and
implements BMPs to filter agricultural runoff. These actions address stressors by reducing fecal,
nutrient, and sediment inputs to project streams, and ultimately to the Ararat River, and reconnect
instream and terrestrial habitats on the Site to upstream and downstream resources. Approximately
20.2-acres of land has been placed under permanent conservation easement to protect the Site in
perpetuity. The established project goals include:
• Improve stream channel stability,
• Treat concentrated agricultural run-off,
• Improve in-stream habitat,
• Restore and enhance native floodplain and wetland vegetation,
• Exclude livestock from streams, and
• Permanently protect the project Site from harmful uses.
The Site is meeting the required stream, vegetation, and hydrology success criteria for Monitoring Year
3 (MY3). In MY3 the Site has met the required stream success criteria. The average planted stem density
is 460 stems per acre and all plots met the MY3 density criteria. Three bankfull events were documented
on the Venable Creek Reach 3 in MY3. The Site is on track to meet the MY7 bankfull flow requirements.
No stream areas of instability were documented, and areas monitored per IRT request have remained
stable. All fences are intact, and no encroachments present at the Site as of October 2023. Invasive
species areas will continue to be monitored and adaptive management measures will be implemented
as necessary to benefit the ecological health of the Site.

Section 1: PROJECT OVERVIEW
1.1 Project Quantities and Credits
Wildlands Engineering, Inc. (Wildlands) implemented a full-delivery stream mitigation project at
the Honey Mill Mitigation Site (Site) for the North Carolina Department of Environmental Quality
(DEQ) Division of Mitigation Services (DMS). The project restored and enhanced a total of 8,683
linear feet (LF) of perennial and intermittent stream in Surry County, NC. The Site is located within
the Rutledge, Stoney and Flat Shoal Creek – Ararat River targeted local watershed (TWL)and NC
Division of Water Resources (DWR) Subbasin 03-07-03. A conservation easement has been
recorded and is in place on 20.2 acres. The project is providing 4,793.432 cool stream mitigation
units (SMUs) for the Yadkin River Basin Hydrologic Unit Code (HUC) 03040101110020. The Site
contains eight unnamed tributaries (UTs) to Venable Creek (UT1, UT2, UT2A, UT2B, UT3, UT4, UT5,
and UT6) and the mainstem of Venable Creek, which has been broken into four reaches and flows
in a north easterly direction through the Site. Multiple riparian wetlands exist on-site; however, no
credit is being sought for project wetlands.
Please refer to Table 1 and Table 1.1 for project credits by stream and the credit summary table
respectively. Annual monitoring will be conducted for seven years with close-out anticipated to
commence in 2027 given the success criteria are met.

1.3 Project Attributes
The Site’s immediate drainage area as well as the surrounding watershed has a long history of
agricultural activity. Stream and wetland functional stressors for the Site were related to both
historic and current land use practices. Major stream stressors for the Site pre-restoration included
livestock trampling and fecal coliform inputs, lack of stabilizing stream bank and riparian
vegetation, active erosion, and incision. The effects of these stressors resulted in channel
instability, degraded water quality, and the loss of both aquatic and riparian habitat throughout
the Site’s watershed when compared to reference conditions.
The overall Site topography consists of steep, confined, and moderately confined valleys along the
tributaries and flow into a more open and gradually sloped valley along the mainstem of Venable
Creek. The project begins at a roadway culvert located at the intersection of Little Mountain
Church Road and Venable Creek. The watersheds for UT3, UT4, and UT6 are roughly bound by
Venable Farm Road to the west. All of the reach watersheds are encompassed by the Venable
Creek watershed, which extends south past Little Mountain Church Road. The Site is typically
defined by forested and agricultural land use with sporadic development of rural homes.
Pre-construction conditions are outlined in Table 3 below and Table 8 of Appendix C.

1.4 Monitoring Year 3 Data Assessment
Annual monitoring for MY3 was conducted between January and October 2023. The stream, vegetation,
and hydrologic success criteria for the Site follows the approved success criteria presented in the Honey
Mill Mitigation Plan (Wildlands, 2020).
1.4.1 Vegetation Assessment
Supplemental Planting Background, IRT Approval, and Table 7 Densities
Please note that Table 7 only summarizes stem densities for the species included in the approved
Mitigation Plan Performance Standard. However, with IRT approval, Wildlands conducted supplemental
planting in 2.5 acres of wetland across the Site to support woody stem growth in March of 2022. During
the same planting, additional stems were also planted in the enhancement II reaches with existing forest
(approximately 7 acres) per IRT request. All species approval and substitutions were documented in the
MY1 Annual Monitoring Report (Wildlands, 2021) and MY2 Annual Monitoring Report (Wildlands, 2022).
Please refer to the IRT approved planted supplemental stems species and quantities in Appendix F.
The approved supplemental wetland and riparian species have been included in the vegetative survey
and factored into the density and species composition for all vegetation data analysis as “Approved Post
Mitigation Plan” species. To account for the IRT approved supplemental species please refer to Table 6
“Post Mitigation Plan Performance Standard” densities discussed in the results below.
Permanent and Mobile Vegetation Plot Results
The MY3 permanent plot planted stem density using the “Post Mitigation Plan” performance
standard ranged from 324 to 486 stems per acre. All densities within the permanent plots (9/9)
exceeded the MY3 criteria of 320 stems per acre. The MY3 “Post Mitigation Plan” planted stem
densities in random mobile vegetation plots ranged from 324 to 688 stems per acre and all 5 mobile
plots met the MY3 density criteria. The mobile plots are distributed across the Site to provide
representative data of the open planting riparian corridor.
IRT Requested Forested Transect Results
As requested by the IRT in MY2, two forested woody vegetation transects have been added to monitor
the survivorship of the shaded supplemental planting and will be assessed through MY7 but are not held
to the Site’s density or height requirements. Forested transect 1 was established on UT2 R1 and had a
total stem count of 14 planted stems in MY2 and 13 stems in MY3 resulting in a 93% survival rate.
Honey Mill Mitigation Site
Monitoring Year 3 Annual Report – FINAL 1-7
Forested transect 2 was established on UT4 and had a total stem count of 11 stems in MY2 and 9 stems
in MY3 for an 82% survival rate.
Vegetation Data Results Summary
Overall, 100% (14/14) vegetation plots met the MY3 density criteria. The average stem height was 3 feet
and is on track to meet MY5 criteria. Additionally, the overall planted density for the Site in MY2 was
460 stems per acre. There was an average of 7 species present per plot in MY3, despite dense
herbaceous cover in wetlands areas. Following the supplemental planting in March 2022 woody stem
survivorship, vigor, and diversity have improved substantially across the Site when compared to the
initial planting.
Please see the Current Condition Plan View (CCPV) maps for permanent vegetation plot locations, MY3
mobile plot locations, and the March 2022 wetland and shaded supplemental planting areas. Vegetation
plot and vegetation transect photographs are located in Appendix A. All vegetation summary data for
plots and transects are in Appendix B.
1.4.2 Stream Assessment
Riffle cross-sections (XS) on the restoration reaches should be stable and show little change in bankfull
area, maximum depth ratio, and width-to-depth ratio. All riffle cross-sections should fall within the
parameters defined for the designated stream type. If any changes do occur, these changes will be
evaluated to assess whether the stream channel is showing signs of instability. Indicators of instability
include a vertically incising thalweg and/or eroding channel banks.
Morphological surveys for MY3 were conducted in June 2023. Cross-section survey results indicate that
channel dimensions are stable and functioning as designed on all restoration reaches with minimal
adjustments from MY1 to MY3. There are no indicators of stream instability across this Site in MY3.
1.4.3 Stream Hydrology Assessment
An automated pressure transducer is being used to monitor for bankfull flow events. Henceforth, this
device is referred to as an automatic “crest gage (CG)” of CG1. A manual crest gage located at XS7 is also
being used to corroborate the results of CG1. At the end of the seven-year monitoring period, four or
more bankfull flow events must have occurred in separate years.
One bankfull event was recorded on Site in MY2 by CG1 on Venable Creek Reach 3. In MY3, three
bankfull events were recorded by CG1 on 4/28/23, 6/20/23, and 8/6/23. Additionally, evidence of a
bankfull event was captured at the manual crest gage in August 2023. Therefore, two bankfull events
have been recorded in two separate years, the Site is on track to meet the performance criteria of four
bankfull events occurring in separate years during the monitoring period. The 30th and 70th percentile
data were collected from the Mount Airy 2 W, WETS station for years 1971-2020. As of August 2023,
there has been an annual precipitation total of 30.95 inches per USGS 362416080334345 RAINGAGE AT
ARARAT RIVER AT ARARAT, NC. The amount of precipitation the Site experiences is likely to fall in the
average range for MY3.
The manual crest gage and automatic crest gage locations are included on the MY3 CCPV Figures 1a - 1d.
Please refer to Appendix D for hydrology summary data and gage plots, and the Supplemental
Photographs located in Appendix A for bankfull documentation at the manual crest gage.

Monitoring Year 3 Annual Report – FINAL 1-8
1.4.4 Areas of Concern and Management Activity
Stream Stability
The streams appear stable and functioning with vegetation developing on the channel banks. No areas
of instability were noted during the MY3 visual assessment that took place on 8/30/23.
Per IRT request, a few areas that appeared to be stabilizing in MY2 have continued to be monitored in
MY3. The spring wetland seep in the right floodplain of Venable Creek Reach 3 provides important
floodplain storage and is filling in with stabilizing vegetation. The pour point from the seep to the
channel is stable. Wildlands will continue to monitor the seep in future monitoring years. UT2B (not for
credit) which was dry during the MY2 Site walk, was flowing during the MY3 visual assessment on
8/30/23 and has remained stable. During dry times of the year, UT3 flows subsurface to the Venable
Creek Reach 3 confluence. A marker was installed at the UT3 confluence to monitor vertical incision and
no incision has occurred since installation in MY2. The meander bend above the UT3 confluence has
continued to fill in with willows armoring the bank after being live staked in before the start of the MY3
growing season. All of these areas have been monitored and photographed in MY3. Please refer to
Appendix A for the supplemental photolog.
All culverts, crossing areas, and BMPs have remained stable with riparian vegetation filling in nicely in
the surrounding riparian corridor. The visual assessment tables and Supplemental BMP photographs are
located in Appendix A.
Easement Exception and Fencing
There are three areas of easement exceptions that were documented at baseline conditions and will
remain on the CCPV maps throughout the seven-year monitoring period per IRT request. No easement
encroachments were observed in MY3.
Additional fencing was installed and any breaks in fencing were also repaired in September 2022. A full
boundary inspection has been completed in MY3. All fences on the Site are intact and no encroachments
were present as of October 2023.
Invasive Species Management
There were four established wooded areas with understory invasive species including multiflora rose
(Rosa multiflora), Japanese barberry (Berberis thunbergia), and Chinese privet (Ligustrum sinense).
within the project area. These areas occupy less than 2% of the easement and are located within the
existing forests along UT2, UT2A, UT3, and UT6, as shown on CCPV Figures 1a - 1d.
Treatments in MY2 were effective and there was a reduction in density of invasives within the mapped
polygons from MY2 to MY3. In order to continue to keep the population in check throughout MY3, re-
sprout treatments took place in May and July of 2023. Invasive areas will continue to be monitored for
re-sprouts and treated as necessary. The open planting areas have established native herbaceous
vegetation and are largely free of invasive species. See the vegetation condition assessment Table 5 in
Appendix A.
1.5 Monitoring Year 3 Summary
Overall, the Site has met the required stream success criteria for MY3. The average planted stem density
was 460 stems per acre and all vegetation plots met the MY3 density requirement of 320 stems per
acre. Geomorphic surveys indicate that cross-section bankfull dimensions closely match the baseline
monitoring with some minor adjustments, and streams are functioning as intended. Three bankfull
events were documented in MY3, and the Site is on track to meet the MY7 bankfull flow requirements.
Honey Mill Mitigation Site
Monitoring Year 3 Annual Report – FINAL 1-9
The MY3 visual assessment identified a few areas of invasive vegetation re-sprouts in wooded
enhancement II reaches that were treated as needed throughout the year. The open planting areas have
established native herbaceous vegetation and are largely free of invasive species. No stream areas of
instability were documented. No easement encroachment was observed on the Site and boundary is
intact. Wildlands will continue to monitor the Site and adaptive management measures will be
implemented as necessary to benefit the ecological health of the Site.

Monitoring Year 3 Annual Report – FINAL 2-1
Section 2: METHODOLOGY
Geomorphic data were collected following the standards outlined in The Stream Channel Reference Site:
An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in the Stream Restoration: A Natural
Channel Design Handbook (Doll et al., 2003). All Integrated Current Condition Mapping was recorded
using a Trimble handheld GPS with sub-meter accuracy and processed using Pathfinder and ArcGIS.
Stream gages were installed in riffles and monitored quarterly. Hydrologic monitoring instrument
installation and monitoring methods are in accordance with the United States Army Corps of Engineers
(USACE, 2003) standards. Vegetation monitoring protocols followed the Carolina Vegetation Survey-EEP
Level 2 Protocol (Lee et al., 2008); however, vegetation data processing follows the NCDMS Vegetation
Data Entry Tool and Vegetation Plot Data Table (NCDMS, 2020).

Invasive Areas of
Concern
Invasives may occur outside of planted areas and within the easement and will
therefore be calculated against the total easement acreage. Include species with the
potential to directly outcompete native, young, woody stems in the short‐term or
community structure for existing communities. Invasive species included in
summation above should be identified in report summary.

Encroachment Areas
Encroachment may be point, line, or polygon. Encroachment to be mapped consists of
any violation of restrictions specified in the conservation easement. Common
encroachments are mowing, cattle access, vehicular access. Encroachment has no
threshold value as will need to be addressed regardless of impact area.
