Holman Mill Mitigation Site
Monitoring Year 4 Annual Report - Final i
EXECUTIVE SUMMARY
Wildlands Engineering, Inc. (Wildlands) completed a full delivery project at the Holman Mill Mitigation
Site (Site) for the North Carolina Department of Environmental Quality Division of Mitigation Services
(DMS) to restore and enhance a total of 8,717 linear feet (LF) of perennial and intermittent stream in
Alamance County, NC. It is anticipated that the Site will generate 3,884 Stream Mitigation Units (SMUs)
through the restoration and enhancement of six unnamed tributaries (UT to Pine Hill Branch, UT1, UT1A,
UT2, UT2A, and UT2B). The project is located in the Cape Fear River Basin Hydrologic Unit Code (HUC)
03030002 (Cape Fear 02) near Snow Camp, NC (Figure 1) and is within the Cane Creek Targeted Local
Watershed (TLW) (HUC 03030002050050). On-site streams flow into Cane Creek and eventually into the
Haw River.
The Site is located within the Jordan Lake Water Supply Watershed, which has been designated as a
Nutrient Sensitive Water. The TLW was identified in DMS’s Cape Fear River Basin Restoration Priorities
2009 (RBRP) report. The RBRP plan identifies agricultural operations and degraded water quality based
on “fair” and “good-fair” benthic ratings as the impairments in the Cane Creek watershed. The RBRP
report also identifies the successful completion of a number of stream and wetland projects within the
Cane Creek watershed. The Site fully supports the Cataloging Unit (CU)-wide functional objectives stated
in the 2011 Request for Proposals to reduce and control nutrient inputs, reduce and control sediment
inputs, and protect and augment Significant Natural Heritage Areas in the Cape Fear 02 River Basin.
The mitigation project is intended to provide numerous ecological benefits within the Cape Fear River
Basin. While many of these benefits are limited to the Site project area; others, such as pollutant
removal and improved aquatic and terrestrial habitat, have more far-reaching effects. Expected
improvements to water quality and ecological processes are outlined below as project goals and
objectives. These project goals were established with careful consideration of the goals and objectives
described in the RBRP and to meet the DMS’s mitigation needs, while maximizing the ecological and
water quality uplift within the watershed. The following project specific goals established in the
mitigation plan (Wildlands, 2015) are to:
• Reduce fecal coliform, nitrogen, and phosphorous inputs by removing cattle from streams and
establishing and augmenting a forested riparian corridor to intercept and process sediment and
nutrients before they reach the channel during storm events;
• Reduce sediment loads by stabilizing eroding stream banks;
• Return a network of streams to a stable form that is capable of supporting biological functions;
• Install instream structures to improve bed and bank stability, create fish and macroinvertebrate
habitat, and help oxygenate streamflows; and
• Protect existing high quality streams and forested buffers.
The project is helping meet the goals for the watershed and providing numerous ecological benefits
within the Cape Fear River Basin. While many of these benefits are limited to the project area, others,
such as pollutant removal and reduced sediment loading have farther-reaching effects. In addition,
protected parcels downstream of the Site promote cumulative project benefits within the watershed.
The Site construction and as-built surveys were completed between January and April 2016. A
conservation easement is in place on 32.4 acres of the riparian corridors to protect them in perpetuity.
Monitoring Year 4 (MY4) site visits and assessments were completed between the months of January
and October 2019 to visually assess the conditions of the project and collect stream hydrology data. Per
Interagency Review Team (IRT) guidelines, detailed monitoring and analysis of vegetation, substrate,
and channel cross-sectional dimensions were not required during MY4. Visual observations, hydrology

Monitoring Year 4 Annual Report - Final ii
data, and management practices are included in this report. To preserve the clarity and continuity of
reporting structure, this report maintains section and appendix numbering from previous monitoring
reports. Omitted sections are denoted in the table of contents.
Overall, Site performance for vegetation, stream geomorphology, and hydrology meet success criteria
for MY4. Vegetation appears healthy and to be performing adequately to attain the interim success
criteria at the end of MY5. Limited erosion was observed on UT2 Reach 4 between station 214+35 and
214+50. Visual observation indicated that stream channels have remained geomorphically stable and
multiple bankfull events were recorded on all streams during MY4. Two low growth areas totaling 1.2
acres were replanted in December 2018. Several vegetative species throughout the Site were
overgrowing planted trees, stunting their growth. A tree release took place in April 2019 on 3.1 acres. A
0.2-acre population of sweet gum was very dense and was removed in April 2019. The fencing that was
damaged during Hurricane Florence was repaired in August 2019.

Monitoring Year 4 Annual Report - Final 1-1
Section 1: PROJECT OVERVIEW
The Holman Mill Mitigation Site (Site) is located in southern Alamance County, southeast of Snow Camp
off of Holman Mill Road (Figure 1). The Site is located within the Jordan Lake Water Supply Watershed
(HUC 03030002050050) which has been designated as a Nutrient Sensitive Water. The Site is in in the
Carolina Slate Belt of the Piedmont Physiographic Province (USGS, 1998). The project watershed consists
primarily of agricultural and wooded land. The drainage area for the project site is 1,077 acres (1.68
square miles).
The project streams consist of six unnamed tributaries to Pine Hill Branch. Stream restoration reaches
include UT1 (Reach 1 and 3), UT2 (Reach 3 and 4) and UT2A. Stream enhancement I (EI) and
enhancement II (EII) reaches included UT1 (Reach 2 and 4), EII; UT2 (Reach 1), EII; UT2 (Reach 2), EI;
UT2B, EII; UT1A, EII; and UT to Pine Hill Branch, EII. Mitigation work within the Site included restoration
and enhancement of 8,717 linear feet (LF) of perennial and intermittent stream channels. The riparian
areas were planted with native vegetation to improve habitat and protect water quality. The final
mitigation plan was submitted and accepted by the DMS in May 2015. Construction activities were
completed by Land Mechanic Designs, Inc. in March 2016. Planting and seeding activities were
completed by Bruton Natural Systems, Inc. in March 2016. Baseline monitoring (MY0) was conducted
between January 2016 and April 2016. Annual monitoring will occur for seven years with the close-out
anticipated to commence in 2023 given the success criteria are met. Appendix 1 provides more detailed
project activity, history, contact information, and watershed/site background information for the Site.
A conservation easement (32.4 ac; Deed Book 3472, Page 968; Deed Book 3472, Page 951) has been
recorded and is in place along the stream riparian corridors to protect them in perpetuity within two
tracts; a tract owned by the Russell B. Hadley Revocable Trust and a tract owned by the M. Darryl
Lindley Revocable Trust, respectively. The project is expected to provide 3,884 SMU’s by closeout.
A project vicinity map and directions are provided in Figure 1 and project components are illustrated in
Figure 2.
1.1 Project Goals and Objectives
Prior to construction activities, the streams and vegetative communities on the Site had been severely
impacted due to direct livestock access to the streams and riparian zones. Table 4 in Appendix 1 and
Tables 10a through 10c in Appendix 4 of the MY3 Report present the pre-restoration conditions in
detail.
This Site is intended to provide numerous ecological benefits within the Cape Fear River Basin. While
many of these benefits are limited to the Site, others such as pollutant removal and reduced sediment
loading have more far-reaching effects. Expected improvements to water quality and ecological
processes are outlined below as project goals and objectives. These project goals were established with
careful consideration of goals and objectives that were described in the RBRP and to meet the DMS
mitigation needs while maximizing the ecological and water quality uplift within the watershed.
The following project goals and related objectives established in the mitigation plan (Wildlands, 2015)
included:
The primary project goals will be:
• Reduce fecal coliform, nitrogen, and phosphorous inputs by removing cattle from streams and
establishing and augmenting a forested riparian corridor to intercept and process sediment and
nutrients before they reach the channel during storm events;
• Reduce sediment loads by stabilizing eroding stream banks;
Holman Mill Mitigation Site
Monitoring Year 4 Annual Report - Final 1-2
• Return a network of streams to a stable form that is capable of supporting biological functions;
• Install instream structures to improve bed and bank stability, create fish and macroinvertebrate
habitat, and help oxygenate streamflows; and
• Protect existing high-quality streams and forested buffers.
Secondary project objectives are expected to include:
• Improving instream nutrient cycling by incorporating woody debris into constructed riffles and
bank stabilization measures;
• Reducing thermal loadings through establishment of riparian shading;
• Reconnecting channels with floodplains to raise the local water table; and
• Create and implement a stream and riparian area restoration design that is both natural and
aesthetically pleasing.
1.2 Monitoring Year 4 Data Assessment
Annual monitoring and quarterly site visits were conducted during MY4 to assess the condition of the
project. The vegetation and stream success criteria for the Site follows the approved success criteria
presented in the Holman Mill Mitigation Project Mitigation Plan (Wildlands, 2015).
1.2.1 Vegetative Assessment
Detailed vegetation inventory and analysis is not required during MY4. Visual assessment during MY4
indicated that vegetation is healthy and performing adequately to attain interim success criteria of 260
planted stems per acre and the end of MY5 and terminal success criteria of 210 planted stems per acre
and averaging ten feet in height.
1.2.2 Vegetation Areas of Concern
Two areas of low stem density identified in MY3 were replanted in December 2018 totaling 1.2 acres
(Figure 3.1-3.2). One area is along UT2 Reach 3, and the other is along UT to Pine Hill Branch upstream
of its confluence with UT1. A mixture of one-gallon container and bare root green ash (Fraxinus
pennsylvanica), sycamore (Platanus occidentalis), river birch (Betula nigra), swamp chestnut oak
(Quercus michauxii), and willow oak (Quercus phellos) were planted at a density of 204 stems per acre.
Visual monitoring will continue to assess the survivability of the supplemental planting.
A high-density area of sweetgum (Liquidambar styraciflua) along UT2 Reach 3 was identified in MY3
totaling 0.2 acres (Figure 3.2). This area was mechanically and chemically treated in April 2019 and will
continued to be visually monitored for sweetgums.
Blackberry (Rubus occidentalis), Japanese honeysuckle (Lonicera japonica), and coralberry
(Symphoricarpos orbiculatus) were observed overcrowding the planted trees throughout the Site and
stunting their growth (Figure 3.1-3.2). A mechanical and chemical tree release was performed in April
2019 on 3.1 acres throughout the Site. Trees have thrived in the areas where the tree release was
performed. Visual monitoring will continue to assess the health of the planted trees.
1.2.3 Stream Assessment
Detailed dimensional survey and analysis is not required for MY4. Visual monitoring indicated that the
stream channel is performing as desired. No deposition or erosion exceeding approximate natural levels
was observed. See Appendix 2 for stream photographs and visual assessment data.
During a site visit on September 26, 2019 dry channel conditions were observed at the Site. This is not
unexpected for a small Slate Belt stream during drought conditions. Alamance County was experiencing
moderate drought conditions at the time, according to the United States Drought Monitor (2019).

Monitoring Year 4 Annual Report - Final 1-3
1.2.4 Stream Areas of Concern
Localized erosion was observed around one log sill affecting the downstream pool between stations
214+35 and 214+50 on UT2 Reach 4 (Figure 3.2). The length of channel affected by the scour is
approximately 15 linear feet. This area will continue to be monitored and remedial action will be taken if
necessary.
1.2.5 Hydrology Assessment
At the end of the seven-year monitoring period, two or more bankfull events must have occurred in
separate years within the restoration reaches. Multiple bankfull events were recorded on all restoration
reaches during MY4 and multiple bankfull events were recorded on each reach during MY1, MY2 and
MY3, resulting in attainment of the stream hydrology assessment criteria. Refer to Appendix 5 for
hydrologic data.
1.2.6 Maintenance Plan
As described above in Section 1.2.2 additional trees were planted during the winter of 2018 in two low
stem density areas shown on the CCPV Maps (Figure 3.1-3.2). Blackberry, Japanese honeysuckle,
coralberry, and sweetgum were mechanically and chemically treated on site. Visual monitoring will
continue to assess the health and density of the planted trees throughout the Site.
A small section of the fencing along UT to Pine Hill Branch that was damaged during Hurricane Florence
was repaired in August 2019. Since cattle did not have access to this portion of the Site, we waited for
this area to dry out before accessing it with equipment to repair the fence.
1.3 Monitoring Year 4 Summary
Visual assessment indicated that all project streams are geomorphically stable and functioning as
designed. A small localized area of erosion is occurring between stations 214+35 and 214+50 along UT2
Reach 4. The erosion is confined to one log sill and will be assessed during subsequent monitoring years.
Survival and growth of planted trees appear to meet interim success criteria and supplemental planting
was completed in December 2018 in two low growth areas. Tree release was completed in April 2019 for
blackberry, Japanese honeysuckle, coralberry, and sweetgum and planted trees look healthy. Hydrology
criteria has been attained for the duration of the project and multiple bankfull events were recorded
again during MY4. The damaged fence along UT to Pine Hill Branch was repaired in August 2019.
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. Narrative background and supporting
information formerly found in these reports can be found in the Mitigation Plan documents available on
DMS’s website. All raw data supporting the tables and figures in the appendices are available from DMS
upon request.
