EXECUTIVE SUMMARY
Wildlands Engineering Inc. (Wildlands) implemented a full delivery project at the Henry Fork Mitigation
Site (Site) for the North Carolina Division of Mitigation Services (DMS) to restore 3,057 linear feet (LF) of
perennial streams and enhance 2,626 LF of intermittent streams, enhance 0.68 acres of existing
wetlands, rehabilitate 0.25 acres of existing wetlands, and re-establish 3.71 acres of wetlands in
Catawba County, NC. The Site is expected to generate 4,807 stream mitigation units (SMUs) and 4.22
wetland mitigation units (WMUs) (Table 1). The Site is located near the city of Hickory in Catawba
County, NC, in the Catawba River Basin; eight -digit Cataloging Unit (CU) 03050102 and the 14 -digit
Hydrologic Unit Code (HUC) 03050102010030 (Figure 1).
The project's compensatory mitigation credits will be used in accordance with the In -Lieu Fee (ILF)
Program Instrument dated July 28, 2010, the expanded service area as defined under the September 12,
2006 PACG memorandum, and/or DMS acceptance and regulatory permit conditions associated with
DMS ILF requirements. Hydrologic Unit Code (HUC) 03050102010030, Lower Henry Fork, was identified
as a Targeted Local Watershed (TLW) in DMS' 2007 Catawba River Basin Restoration Priority (RBRP)
Plan. The project streams consist of four unnamed tributaries (UTs) to the Henry Fork River on the site
of a former golf course, referred to herein as UT1, UT2, UT1A, and UT113 (Figure 2). The project also
consists of several wetland restoration components, as well as buffer planting along Henry Fork. The
project watershed consists of agricultural, forested, and residential land uses.
The RBRP identifies a restoration goal for all streams within HUC 03050102 of removing conditions which
cause sediment impairments, including mitigating stressors from stormwater runoff. The Henry Fork
watershed was also identified in the 2005 North Carolina Wildlife Resource Commission's Wildlife Action
Plan as a priority area, which calls for conservation and restoration of streams and riparian zones. In
addition, the 2010 DWQ Catawba River Basin Plan indicated that the section of Henry Fork that drains to
the project area is impaired for high turbidity, among other stressors. The intent of this project is to help
meet the goals for the watershed outlined in the RBRP and provide numerous ecological benefits within
the Catawba River Basin.
The project goals established in the mitigation plan (Wildlands, 2015) were completed with careful
consideration of goals and objectives that were described in the RBRP and to meet DMS mitigation needs
while maximizing the ecological and water quality uplift within the watershed. The project goals
established in the mitigation plan focused on permanent protection, reestablishing natural hydrology
and vegetation, reducing water quality stressors and enhancing terrestrial and aquatic habitat. The
decommissioning of the existing golf course, establishment of a permanent easement, and completion of
construction and planting efforts have set a new trajectory that is intended to attain these goals, and
monitoring assessments are being completed as proposed to measure established success criteria.
The Site construction and as -built surveys were completed between November 2015 and March 2016.
Monitoring Year 2 (MY2) assessments and site visits were completed between April and November 2017
to assess the conditions of the project. Overall, the Site has met the required stream and vegetation
success criteria for MY2, and is on track to meet wetland hydrologic success criteria. All restored and
enhanced streams are stable and functioning as designed.
Four automated and manual crest gages were installed on the Site to document bankfull events. Each
stream and manual crest gage recorded a bankfull event. Vegetation assessment indicates that overall
average stem density for the Site is 594 stems per acre, and is therefore on track to meet the MY3
requirement of 320 stems per acre. Of the nine groundwater monitoring gages installed within the
wetland rehabilitation and re-establishment zones, five met the success criteria (water table with 12
inches of the ground surface for 8.5% of the growing season consecutively). GWGs 5 and 9 were

installed April 7, 2017 and the data is also being included. It is anticipated that these wetland areas will
continue to recharge and meet hydrologic success criteria in the upcoming monitoring years as
precipitation normalizes, especially during the winter months.

Section 1: PROJECT OVERVIEW
The Site is located near the city of Hickory in Catawba County, NC, in the Catawba River Basin; eight -digit
Cataloging Unit (CU) 03050102 and the 14 -digit Hydrologic Unit Code (HUC) 03050102010030 (Figure 1).
Access to the Site is via Mountain View Road, approximately one mile southwest of Hickory, North
Carolina. Situated in the Inner Piedmont Belt of the Piedmont Physiographic Province (USGS, 1998), the
project watershed consists of agricultural, forested, and residential land uses. The drainage area for the
Site is 178 acres. (0.28 square miles).
The project streams consist of four unnamed tributaries (UTs) to the Henry Fork River on the site of a
former golf course, referred to herein as UT1, UT2, UT1A, and UT113. Stream restoration reaches
included UT1 (Reach 1 and 2) and UT113, together comprising 3,057 linear feet (LF) of perennial stream
channel. Stream enhancement reaches included UT1A and UT2, together totaling 2,626 LF. Stream
enhancement activities for UT1A and UT2 were the same as for restoration reaches, however the
tributaries are intermittent, and as such were credited as enhancement. The riparian areas of the
tributaries, as well as a 100 foot -wide buffer of the Henry Fork, were planted with native vegetation to
improve habitat and protect water quality. Wetland components included enhancement of 0.68 acres of
existing wetlands, rehabilitation of 0.25 acres of existing wetlands and re-establishment of 3.71 acres of
wetlands.
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. A conservation
easement has been recorded and is in place on 48.06 acres (Deed Book 03247, Page Number 0476-
0488) within a tract owned by WEI-Henry Fork, LLC. The project is expected to generate 4,838 stream
mitigation units (SMUs) and 4.22 wetland mitigation units (WMUs). Annual monitoring will be
conducted 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 this project.
Directions and a map of the Site are provided in Figure 1 and project components are illustrated for the
Site in Figure 2.
1.1 Project Goals and Objectives
This Site is intended to provide numerous ecological benefits within the Catawba River Basin. The Site
will help meet the goals for the watershed outlined in the RBRP and provide numerous ecological
benefits within the Catawba River Basin. While many of these benefits are limited to the Henry Fork
project area, others, such as pollutant removal, reduced sediment loading, and improved aquatic and
terrestrial habitat, have farther -reaching effects. Expected improvements to water quality and ecological
processes are outlined below as project goals and objectives. These project goals established were
completed 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 specific goals established in the mitigation plan (Wildlands, 2015) include:
• Permanently protect the project site from harmful uses; and
• Correct modifications to streams, wetlands and buffers;
• Improving and re-establishing hydrology and function of previously cleared wetlands;
• Reducing current erosion and sedimentation;
• Reduce nutrient inputs to streams and wetlands, and to downstream water bodies;
Henry Fork Mitigation Site
Monitoring Year 2 Annual Report— FINAL 1-1
• Improve instream habitat; and
• Provide and improve terrestrial habitat, and native floodplain forest.
The project goals were addressed through the following project objectives:
• Decommissioning the existing golf course and establishing a conservation easement on the Site
will eliminate direct chemical fertilizer, pesticide and herbicide inputs;
• Resizing and realigning channels to address stream dredging and ditching. Planting native woody
species in riparian zones which have been maintained through mowing. By correcting these
prior modifications, the channels and floodplains will provide a suite of hydrologic and biological
function;
• Restoring appropriate stream dimensions and juxtaposition of streams and wetlands on the
landscape. Wetlands will be enhanced through more frequent overbank flooding, and also by
reducing the drawdown effect that current ditched channels have on wetland hydrology,
thereby enhancing wetland connectivity to the local water table. The project will extend existing
wetland zones into adjacent areas and support wetland functions;
• Removing historic overburden to uncover relic hydric soils. Roughen wetland re-establishment.
Restore streams for wetland benefit. Each of these will bring local water table elevations closer
to the ground surface. Create overbank flooding, and depressional storage for overland and
overbank flow retention. Decrease direct runoff, and increase infiltration;
• A native vegetation community will be planted on the Site to revegetate the riparian buffers and
wetlands. Conduct soil restoration through topsoil harvesting and reapplication, and leaf litter
harvesting and application from adjacent forested areas. This will return functions associated
with buffers and forested floodplains, as well as enhance soil productivity and bring native
biological activity and seed into the disturbed areas;
• Constructing diverse and stable channel form with varied stream bedform and installing habitat
features, along with removing culverts. These will allow aquatic habitat quality and connectivity
enhancement; and
• Placing a portion of the right bank Henry Fork floodplain under a conservation easement, and
planting all stream buffers and wetlands with native species. Creating a 100 foot -wide corridor
of wooded riparian buffer along that top right bank area and re-establishing native plant
communities, connectivity of habitat within Site and to adjoining natural areas along the river
corridor.
1.2 Monitoring Year 2 Data Assessment
Annual monitoring and quarterly site visits were conducted during MY2 to assess the condition of the
project. The stream, vegetation, and hydrologic success criteria for the Site follows the approved success
criteria presented in the Henry Fork Mitigation Plan (Wildlands, 2015).
1.2.1 Stream Assessment
Morphological surveys for the MY2 were conducted in April 2017. All streams within the site appear to
be stable.
In general, riffle cross sections show little to no change in the bankfull area, maximum depth ratio, or
width -to -depth ratio. Surveyed riffle cross sections fell within the parameters defined for channels of
the appropriate Rosgen (Rosgen, 1994 & 1996) stream type. Pebble counts in UT1 Reach 1 and UT113
indicate maintenance of coarser materials in the riffle features and finer particles in the pool features.
Refer to Appendix 2 for the visual stability assessment table, Current Conditions Plan View (CCPV) map,
and reference photographs. Refer to Appendix 4 for the morphological data and plots.

Monitoring Year 2 Annual Report— FINAL 1-2
1.2.2 Stream 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. According to the stream gages, UT1 and UT1A each had
two bankfull events recorded during MY2. UT113 and UT2 only had one recorded bankfull event during
MY2. During MY1, there was only one recorded bankfull event on UTIA; therefore, the performance
criteria has been partially met for this Site.
In addition to monitoring bankfull events, intermittent streams must be monitored to demonstrate that
stream flow regimes are sufficient to establish an Ordinary High Water Mark, specifically a minimum of
30 consecutive days of flow during periods of normal rainfall. Rainfall in 2017 was consistently low
throughout the year, but especially during the winter months, which resulted in low flow or the absence
of water in streams. UTI and UT1A were observed with water during each site visit; however, UT2 and
UT113 were frequently observed dry. Refer to Appendix 5 for hydrology summary data and plots.
1.2.3 Stream Areas of Concerns
During a site walk, Wildlands and the Inter -Agency Review Team (IRT) observed an area located
between stations 104+00-105+00 of UT1 Reach 1 where water flows subsurface. This area has been
monitored during quarterly visits to understand the issue which is likely related to prior golf course
water management efforts, and remedial maintenance efforts are scheduled for December 2017 to
attempt to resolve the matter.
1.2.4 Vegetative Assessment
Planted woody vegetation is being monitored in accordance with the guidelines and procedures
developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008). A total of 15
vegetation plots were established during the baseline monitoring within the project easement area. All
of the plots were installed using a standard 10 meter by 10 meter plot. The final vegetative success
criteria will be the survival of 210 planted stems per acre in the planted riparian and wetland corridor at
the end of the required monitoring period (MY7). The interim measure of vegetative success for the Site
will be the survival of at least 320 planted stems per acre at the end of the third monitoring year (MY3)
and at least 260 stems per acre at the end of the fifth monitoring year (MY5). Planted vegetation must
average 10 feet in height in each plot at the end of the seventh year of monitoring. If this performance
standard is met by MYS, with stem density trending towards success (i.e., no less than 260 five year old
stems/acre) and there is no invasive species prevalent, monitoring of vegetation on the Site may be
terminated provided written approval is provided by the United States Army Corps of Engineers in
consultation with the NC Interagency Review Team.
The MY2 vegetative survey was completed in July 2017. The 2017 vegetation monitoring resulted in an
average stem density of 594 stems per acre, which is greater than the interim requirement of 320
stems/acre required at MY3. There is an average of 15 stems per plot with an average stem height of 2.4
feet. All 15 of the plots are on track to meet the success criteria required for MY7 (Table 9, Appendix 3).
Refer to Appendix 2 for vegetation plot photographs and the vegetation condition assessment table and
Appendix 3 for vegetation data tables.
1.2.5 Vegetation Areas of Concern
Invasive species including Chinese privet (Ligustrum sinense), Japanese honeysuckle (Lonicera japonica),
and multiflora rose (Rosa multiflora) were present along the northern edge and southern end of the
Site. These areas were treated in accordance with the herbicide application rates used in cut/spray
techniques during MY2 and will be monitored in future years. These species are not impacting survival
rates of planted stems.
Henry Fork Mitigation Site
Monitoring Year 2 Annual Report— FINAL 1-3
Several areas located on the lower portion of the site contained little to no herbaceous ground cover
during monitoring visits earlier in the year. Poor soil nutrients and dry soil conditions could have been
potential factors affecting herbaceous growth; however, the establishment of vegetation is common
and typically occurs by MY2 or MY3 once the ground has been able to acclimate to the recent ground
disturbance. These areas were addressed during the fall of MY2 with an additional seeding and
fertilizing application, and subsequent new growth was observed during the November site visit.
The minor mowing encroachments of the easement has continued along the eastern edge of UTI Reach
1, as shown in the CCPV (Appendix 2). The adjacent landowner has been notified that the activities are
in violation of the easement.
1.2.6 Wetland Assessment
Seven groundwater hydrology gages (GWGs) were established during the baseline monitoring within the
wetland rehabilitation and re-establishment zones (GWGs 1— 4 and 6 — 8). Gages were distributed so
that the data collected would provide a reasonable indication of groundwater levels throughout the
wetland components on the Site. A gage was established in an adjacent reference wetland and is being
utilized to compare with the hydrologic response within the restored wetland areas at the Site. A
barotroll logger (to measure barometric pressure used in the calculations of groundwater levels with
gage transducer data) and a rain gage were also installed on the Site. All monitoring gages were
downloaded on a quarterly basis and maintained on an as needed basis. Two additional gages (GWG 5
and 9) were installed within the Wetland Re -Establishment areas during 2017 (MY2) in order to further
assess wetland performance. In addition, GWG 3 was relocated during 2017. During the initial GWG
installation, GWG 3 was installed in a seep where hydrology was much stronger than the surrounding
area represented by GWG 3. During the MY1 monitoring period, GWG 3 documented groundwater at or
just above the ground surface; therefore, GWG 3 was relocated January 2017 to an area that was more
representative of the surrounding wetlands.
Historical growing season data is not available for Catawba County. Therefore, the growing season from
Burke County, which runs from March 20th to November 11th (236 days), is being used for hydrologic
success. The final performance standard (success criteria) for wetland hydrology will be a free
groundwater surface within 12 inches of the ground surface for 20 consecutive days (8.5%) of the
defined 236 -day growing season under typical precipitation conditions.
Of the nine GWGs, five met the success criteria for MY2. Of the gages that met, the measured
hydroperiod ranged from 6% to 80% of the growing season. The relocated GWG 3 did not meet criteria
during the MY2 period. The GWG 3 hydrology was below the reference gage for a majority of the year;
however, the hydrology reflected improvement during the later portion of the growing season. Refer to
the CCPV in Appendix 2 for the groundwater gage locations and Appendix 5 for groundwater hydrology
summary data and plots.
1.2.7 Adaptive Management Plan
Quarterly site visits will continue to address any areas of concern. If necessary, future adaptive
management will be implemented to improve herbaceous cover, treatment and control of invasive
plants, and remedial action to resolve stream issues.
1.3 Monitoring Year 2 Summary
The streams within the Site are stable and functioning as designed. The average stem density for the Site
is on track to meet the MY7 success criteria and all individual vegetation plots meet the MY2 success
criteria as depicted in the CCPV. Invasive species are being treated as prescribed in the mitigation plan.
Of the nine GWGs, five met the success criteria for MY2. It is anticipated that gages will meet hydrologic
Henry Fork Mitigation Site
Monitoring Year 2 Annual Report— FINAL 1-4
success criteria in the upcoming monitoring years as precipitation normalizes. Two bankfull events were
documented on UT1 and UT1A and one bankfull event was recorded on UT113 and UT2 during MY2.
Therefore, the hydrology success criteria has been partially met for this Site.
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.

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 either a Trimble or Topcon handheld GPS with sub -meter accuracy and processed using Pathfinder
and ArcGIS. Crest gages were installed in surveyed riffle cross sections 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).

DESCRIPTION OF WORKSHEETS IN THIS DOCUMENT------------
Metadata
Description of database file, the report worksheets, and a summary of project(s) and project data.
Project Planted
Each project is listed with its PLANTED stems per acre, for each year. This excludes live stakes.
Project Total Stems
Each project is listed with its TOTAL stems per acre, for each year. This includes live stakes, all planted stems, and all
natural/volunteer stems.
Plots
List of plots surveyed with location and summary data (live stems, dead stems, missing, etc.).
Vigor
Frequency distribution of vigor classes for stems for all plots.
Vigor by Spp
Frequency distribution of vigor classes listed by species.
Damage
List of most frequent damage classes with number of occurrences and percent of total stems impacted by each.
Damage by Spp
Damage values tallied by type for each species.
Damage by Plot
Damage values tallied by type for each plot.
Planted Stems by Plot and Spp
A matrix of the count of PLANTED living stems of each species for each plot; dead and missing stems are excluded.
ALL Stems by Plot and Spp
A matrix of the count of total living stems of each species (planted and natural volunteers combined) for each plot; dead and
missing stems are excluded.
