EXECUTIVE SUMMARY
Wildlands Engineering (Wildlands) completed a full delivery project at the Henry Fork Mitigation Site
(Site) for the North Carolina Department of Environment Quality Division of Mitigation Services (DMS) to
restore 3,087 linear feet (LF) of perennial streams and enhance 2,627 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 4,838 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
Division of Mitigation Services 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 adjacent land to the streams and wetlands is primarily residential.
The Site is located in the Lower Henry Fork watershed which was designated as a Targeted Local
Watershed (TLW) in the DMS' 2007 Catawba River Basin Restoration Priorities (RBRP) plan. 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 NC DWQ Catawba River Basin Plan indicated that the section of Henry Fork that
drains 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 following
project goals established include:
• Decommissioning the existing golf course, with the targeted efforts of establishing a permanent
conservation easement to buffer the streams and Henry Fork floodplain.
• Improving aquatic and terrestrial habitats, including enhanced connectivity and diversity of
habitat.
The Site construction and as -built surveys were completed between November 2015 and March 2016.
Some adjustments were made during construction, as needed, based on site conditions and availability
of materials. These design adjustments included log steps being replaced by rock steps, brush toe
replaced root wads in a few areas, as well as minor grading adjustments. Specific design changes are
detailed in Section 5.1 and in the Record Drawings (Appendix 4). Baseline (MYO) profiles and cross-
section dimensions closely match the design parameters. Cross-section widths and pool depths
occasionally exceed design parameters within a normal range of variability for natural streams; this is
not a concern at this time. With overbank events and vegetation growth, it is expected these stream
channels will narrow up with time. The Site has been built as designed and is on track to meeting the
upcoming monitoring year's success criteria.

Section 1: PROJECT GOALS, BACKGROUND AND ATTRIBUTES
1.1 Project Location and Setting
The Henry Fork Mitigation Site (Site) is a stream and wetland project located in western Catawba County
approximately one mile southwest of the City of Hickory (Figure 1). The project is located on the old
Henry Fork Golf Course. The Site is located on a tract owned by WEI-Henry Fork, LLC (PIN 2791-0888-
3819). A conservation easement was recorded on 48.06 acres with the parcel (Deed Book 03247, Page
0476-0488).
The Site is located 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 Division of Mitigation Services 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.
Located in the Inner Piedmont Belt of the Piedmont Physiographic Province (USGS, 1998), the project
watershed consists of mostly residential, herbaceous fields and forest. The drainage area for the project
site is approximately 178 acres.
The Henry Fork River and the UTs of this Site are located within the NC Division of Water Resources
(NCDWR) subbasin 03-08-35. Henry Fork River (NCDWQ Index No. 11-129-1(12.5)) is classified as C
waters. Class C waters are protected for uses such as secondary recreation, fishing, wildlife, fish and
aquatic life propagation and survival, and agriculture. The Site is approximately 15 miles upstream of the
South Fork Catawba River (Lincolnton) WS -IV, CA water supply watershed. Lower Henry Fork, was
identified as a Targeted Local Watershed (TLW) in DMS' 2007 Catawba River Basin Restoration Priority
(RBRP) Plan. The RBRP identifies a restoration goal for all streams within HUC 03050102 of removing
conditions which cause sediment impairments, including mitigating stressors from storm water runoff.
In addition, the 2010 NC DWQ Catawba River Basin Plan indicated that the section of Henry Fork that
drains the project area is impaired for high turbidity and low pH, among other stressors.
1.2 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
Baseline Monitoring Document and As -Built Baseline 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;
• To resize and realign channels to address stream dredging and ditching. Plant 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;
• By 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.
1.3 Project Structure, Restoration Type and Approach
The final mitigation plan was submitted and accepted by the DMS in September of 2015. Construction,
planting, and as -built survey activities were completed in March 2016 by Land Mechanic Designs, Inc.,
Bruton Natural Systems, Inc., and Kee Mapping & Surveying, PLLC, respectively. Please refer to Appendix
1 for more detailed project activity, history, contact information, and watershed/site background
information.
1.3.1 Project Structure
The project will provide 4,838 stream mitigation units (SMUs) and 4.22 wetland mitigation units
(WMUs). Please refer to Figure 2 for the project component/asset map and Table 1 for the project
component and mitigation credit information for the Site.
1.3.2 Restoration Type and Approach
The designed streams were restored to the appropriate type based on their topographic setting within
the surrounding landscape, hydrologic and climate conditions, and natural vegetation communities. The
Henry Fork Mitigation Site
Baseline Monitoring Document and As -Built Baseline Report -FINAL 1-2
project includes stream restoration and enhancement, along with wetland rehabilitation, re-
establishment and enhancement.
The stream restoration portion of this project includes:
• UT1 Reaches 1 and 2: This restoration stream enters the Site at the forested southern property
boundary and flows north until joining Henry Fork at the downstream property line;
• UT2: This stream enhancement originates from the west of the property and flows due east until
joining UT1;
• UT1A: This stream enhancement originates at the confluence of two hillslope seeps located near
the steep north facing hillside on the eastern half of the Site. This channel flows northward
through the wide floodplain of Henry Fork to its confluence with UTI; and
• UT113: This restoration stream begins at a groundwater seep and flows westward to its
confluence with UT1 Reach 1.
The project design was developed based on reference conditions, representing streams within the
Southern Piedmont Belt region with similar drainage areas, valley slopes, morphology, and bed material.
The restoration of the streams allows for the re-establishment of stream -wetland complexes that create
a unique synergy of aquatic habitats. In addition, the design is tailored towards restoring ecologically
beneficial hydrologic conditions in both the streams and the adjacent floodplain wetland resources. The
reconstructed channel banks were built with stable side sloped, planted with native materials, matted
and seeded for stability. The sinuous plan form of the channel was built to mimic a natural Piedmont
stream. Various types of constructed riffles were installed to provide grade control and address excess
shear stress.
1.4 Project History, Contacts, and Attribute Data
The Site was restored by Wildlands through a full delivery contract with DMS. Tables 2, 3, and 4 in
Appendix 1 provide detailed information regarding the Project Activity and Reporting History, Project
Contacts, and Project Baseline Information and Attributes.

Section 2: PERFORMANCE STANDARDS
The stream and wetland performance criteria for the project site will follow approved performance
criteria presented in Henry Fork Mitigation Plan (2015). Annual monitoring and semi-annual site visits
will be conducted to assess the condition of the finished project. The stream restoration sections of the
project will be assigned specific performance criteria components for stream morphology, hydrology,
and vegetation. Wetland rehabilitation and re-establishment areas will be assigned specific performance
criteria for wetland hydrology and vegetation. Performance criteria will be evaluated throughout the
seven-year post -construction monitoring. If all performance criteria have been successfully met and two
bankfull events have occurred during separate years, Wildlands may propose to terminate stream
and/or vegetation monitoring after year five pending little to no prevalent invasive species issues. An
outline of the performance criteria components follows. An outline of the performance criteria
components follows.
2.1 Streams
2.1.1 Dimension
Riffle cross-sections on the restoration reaches should be stable and should show little change in
bankfull area, maximum depth ratio, and width -to -depth ratio. Per DMS guidance, bank height ratios
shall not exceed 1.2 and entrenchment ratios shall be at least 2.2 for restored C- and E- type channels to
be considered stable. All riffle cross-sections should fall within the parameters defined for channels of
the appropriate 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 or eroding channel banks. Changes in the channel that indicate a movement toward stability or
enhanced habitat include a decrease in the width -to -depth ratio in meandering channels or an increase
in pool depth. Remedial action would not be taken if channel changes indicate a movement toward
stability. It is important to note that in fine-grained and sand bed channels pools and bed forms (ripples,
dunes, etc.) may migrate over time as a natural function of the channel hydraulics. These sorts of bed
changes do not constitute a problem or indicate a need for remedial actions.
2.1.2 Pattern and Profile
Visual assessments and photo documentation should indicate that streams are remaining stable and do
not indicate a trend toward vertical or lateral instability. As mentioned above, migration of pools and
bed forms in fine-grained channels are expected and do not require remedial action.
2.1.3 Substrate
Channel substrate materials will be collected along UT1 Reach 1 and UT113, which are dominated by
cobble and gravel. The remaining streams within the project site are dominated by sand and silt -size
particles. Pebble count and/or bulk sampling procedures along these fine-grained streams would not
show a significant change in bed material size or distribution over the monitoring period.
UT1 Reach 1 and UT113 restoration reaches should indicate a progression towards or the maintenance of
coarser materials in the riffle features and smaller particles in the pool features. A reach -wide pebble
count will be performed in each restoration reach each year for classification purposes. A pebble count
will be performed at each surveyed riffle to characterize the pavement.
Henry Fork Mitigation Site
Baseline Monitoring Document and As -Built Baseline Report -FINAL 2-1
2.1.4 Photo Documentation
Photographs should illustrate the Site's vegetation and morphological stability on an annual basis. Cross-
section photos should demonstrate no excessive erosion or degradation of the banks. Longitudinal
photos should indicate the absence of persistent bars within the channel or vertical incision. Grade
control structures should remain stable. Deposition of sediment on the bank side of vane arms is
preferable. Maintenance of scour pools on the channel side of vane arms is expected.
2.1.5 Bankfull Documentation
Two bankfull flow events must be documented on the restoration and enhancement reaches, within the
seven-year monitoring period. The two bankfull events must occur in separate years. Stream monitoring
will continue until success criteria in the form of two bankfull events in separate years have been
documented. Adequate hydrology for intermittent streams must be documented. Direct measurements
of continuous interval stream flow data will be made with a gage. The flow regime should indicate
sufficient flow to maintain an Ordinary High Water Mark (OHWM), specifically a minimum of 30
consecutive days of flow during periods of normal rainfall. Photographic evidence of streamflow coupled
with rainfall gage data from the project site will be used to help support this assessment.
2.2 Vegetation
The final vegetative success criteria will be the survival of 210 planted stems per acre in the planted
riparian and wetland areas at the end of the required monitoring period (year seven). 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 and at least 260 stems per acre at the end of the fifth year of
monitoring. Planted vegetation must average 10 feet in height in each plot at the end of the seventh
year of monitoring. If this performance standard met by year five and stem density is trending towards
success (i.e., no less than 260 five-year-old stems/acre), monitoring of vegetation on the Site may be
terminated provided written approval is provided by the USACE in consultation with the NC IRT. Invasive
species treatment will be conducted in the mitigation area during the seven-year monitoring period as
needed to ensure the hydrologic and ecologic success of the project.
2.3 Wetlands
The preliminary wetland performance standard used to evaluate the Site's hydrology is that the water
table must be within 12 inches of the ground surface at each gage for a minimum of 20 consecutive days
(8.5%) of the 236 day growing season (March 20 through November 11) for Catawba County. The
growing season was determined from the long-term records from the National Weather Service
provided in the WETS table for the Hickory Regional Airport and may be evaluated at the project site
during the monitoring period using soil temperature loggers in order to base growing season on the
measured data.
2.4 Schedule and Reporting
Monitoring reports will be prepared in the fall of each year of monitoring and submitted to DMS. Based
on the DMS Monitoring Report Template (version 1.5, 6/8/12), the monitoring reports will include the
following:
• Project background which includes project objectives, project structure, restoration type and
approach, location and setting, history and background;
Monitoring plan view map of major project elements including such items as grade control
structures, vegetation plots, permanent cross-sections, stream gages, photo points, and
groundwater gages;

• Photographs showing views of the restored Stream Site taken from fixed point stations;
• Assessment of the stability of the Stream Site based on visual assessments and cross-section
survey;
• Vegetative data as described above including the identification of any invasion by undesirable
plant species;
• Groundwater gage attainment;
• Maintenance issues and remediation measures will be detailed and documented as needed; and
• Wildlife observations.

Section 3: MONITORING PLAN
Monitoring will consist of collecting morphological, vegetative, and hydrological data to assess the
project success based on the restoration goals and objectives on an annual basis or until success criteria
is met. The success of the project will be assessed using measurements of the stream channel's
dimension, substrate composition, permanent photographs, vegetation, surface water hydrology, and
groundwater hydrology. Any areas with identified high priority problems, such as streambank instability,
aggradation/degradation, insufficient groundwater hydroperiod, or lack of vegetation establishment will
be evaluated on a case-by-case basis. The problem areas will be visually noted and remedial actions will
be discussed with DMS staff as needed.
3.1 Stream
Geomorphic assessments follow guidelines outlined in the Stream Channel Reference Sites: An
Illustrated Guide to Field Techniques (Harrelson et al., 1994), methodologies utilized in the Rosgen
stream assessment and classification documents (Rosgen, 1994 and 1996), and in the Stream
Restoration: A Natural Channel Design Handbook (Doll et al, 2003). Please refer to Figure 3 in Appendix
1 for monitoring locations discussed below.
3.1.1 Dimension
In order to monitor the channel dimension, 14 permanent cross-sections were installed along stream
restoration and enhancement I reaches, with riffle and pool sections in proportion to DMS guidance.
Two cross-sections were installed per 1,000 linear feet of stream restoration work, with riffle and pool
sections in proportion to DMS guidance. Each cross-section is permanently marked with capped rebar
installed in concrete and 1/2 inch PVC pipes. Cross-section surveys include points measured at all breaks
in slope, including top of bank, bankfull, edge of water, and thalweg. If moderate bank erosion is
observed at a stream reach during the monitoring period, an array of bank pins will be installed in
representative areas where erosion is occurring for reaches with a bankfull width of greater than three
feet. Bank pins will be installed in at least three locations (one in upper third of the pool, one at the mid-
point of the pool, and one in the lower third of the pool). Bank pins will be monitored by measuring
exposed rebar and maintaining pins flush to bank to capture bank erosion progression. Annual cross-
section and bank pin survey (if applicable) will be conducted in monitoring years one (MY1), two (MY2),
three (MY3), five (MY5), and seven (MY7). Photographs will be taken annually of the cross-sections
looking upstream and downstream.
3.1.2 Pattern and Profile
Longitudinal profile surveys will not be conducted during the seven year monitoring period unless other
indicators during the annual monitoring indicate a trend toward vertical and lateral instability. If a
longitudinal profile is deemed necessary, monitoring will follow standards as described in the 2003
USACE and NCDWR Stream Mitigation Guidance for the necessary reaches. Stream pattern and profile
will be assessed visually as described below in section 3.1.6.
3.1.3 Substrate
Since UT1A, UT2 and UT1 Reach 2 are dominated by sand and silt -size particles, sampling procedures
were not conducted on these streams. Two reach -wide pebble counts were conducted; one on UT1 and
one on UT113. A wetted pebble count was performed at each surveyed riffle on UT1 Reach 1 Upper and
Lower, as well as on UT113, to characterize the pavement. Substrate analysis will be conducted in
monitoring years one (MY1), two (MY2), three (MY3), five (MY5), and seven (MY7).
Henry Fork Mitigation Site
Baseline Monitoring Document and As -Built Baseline Report -FINAL 3-1
3.1.4 Photo Reference Points
A total of 29 permanent photograph reference points were established within the project area after
construction. Photographs will be taken looking upstream and downstream once a year to visually
document stability for seven years following construction. Permanent markers were established so that
the same locations and view directions on the Site are monitored each year. Cross-sectional photos will
be taken of each permanent cross-section looking upstream and downstream. Reference photos will
also be taken for each of the vegetation plots. Representative digital photos of each permanent photo
point, cross-section and vegetation plot will be taken on the same day of the stream and vegetation
assessments are conducted. The photographer will make every effort to consistently maintain the same
area in each photo over time.
3.1.5 Hydrology Documentation
Bankfull events will be documented using crest gages, pressure transducers (stream gages),
photographs, and visual assessments such as debris lines. Four stream hydrology monitoring stations
were installed each with one crest gage and one pressure transducer (stream gage); one on UT1, one on
UT1A, one on UT113, and one on UT2. The stream hydrology gages were installed within a surveyed riffle
cross-section of the restored channels. The stream hydrology gages will be checked at each site visit to
determine if a bankfull event has occurred and the intermittent stream channels are demonstrating a
flow regime that would be expected to maintain an Ordinary High Water Mark (OHWM). Photographs
will be used to document the occurrence of staining and debris and/or sediment deposition on the
floodplain.
3.2 Vegetation
Planted woody vegetation will be monitored in accordance with the guidelines and procedures
developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2006) to monitor and
assess the planted woody vegetation. A total of 15 vegetation plots were established within the project
easement area. All of the plots were established as standard 10 meter by 10 meter squares.
Vegetation plots were randomly established within the planted corridor of the restoration areas to
capture the heterogeneity of the designed vegetative communities. The vegetation plot corners have
been marked and are recoverable either through field identification or with the use of a GPS unit.
Reference photographs at the origin looking diagonally across the plot to the opposite corner were
taken during the baseline monitoring in February 2016. Subsequent annual assessments following
baseline survey will capture the same reference photograph locations. Species composition, density and
survival rates will be evaluated on an annual basis by plot and for the entire Site. Individual plot data will
be provided and will include diameter, height, density, vigor, damage (if any), and percent survival.
Planted woody stems will be marked annually as needed based off of a known origin so they can be
found in succeeding monitoring years. Mortality will be determined from the difference between the
baseline year's living planted stems and the current year's living planted stems.
3.3 Wetlands
3.3.1 Hydrology
In order to monitor the wetland rehabilitation and re- establishment areas, wetland hydrology will be
monitored using groundwater monitoring gages and installed according to USACE recommended
procedures. The gages used for this activity are typically In-situ Level TROLL® 100 or 300 pressure
transducers. An additional gage will be established in an adjacent reference wetland and will be utilized
to compare the hydrologic response within the restored wetland areas at the Site. The proposed
location of monitoring gages and the proposed reference gage are denoted in Figure 3. All gages will be
Henry Fork Mitigation Site
Baseline Monitoring Document and As -Built Baseline Report -FINAL 3-2
set to record the ground water level two times per day. An onsite rain gage will be installed to record
daily rainfall, and will be utilized to assess whether typical weather conditions occur during the
monitoring period. If a particular groundwater gage does not meet the performance standard for a given
monitoring year, rainfall patterns will be analyzed and the hydrograph will be compared to that of the
reference wetlands to assess whether atypical weather conditions occurred during the monitoring
period.
3.4 Visual Assessments
Visual assessments will be performed along all stream, buffer, and wetland areas on a semi-annual basis
during the seven-year monitoring period. Problem areas will be noted and included in the Current
Condition Plan View Map (CCPV), such as channel instability (i.e. lateral and/or vertical instability, in -
stream structure failure/instability and/or piping, headcuts), vegetated health (i.e. low stem density,
vegetation mortality, invasive species or encroachment) beaver activity, or easement encroachments.
Areas of concern will be mapped and photographed, accompanied by a written description in the annual
report. Problem areas will be re-evaluated during each subsequent visual assessment. Should remedial
actions be required, remediation approaches will be provided in the annual monitoring report

Baseline Monitoring Document and As -Built Baseline Report -FINAL 3-3
Section 4: MAINTENANCE AND CONTINGENCY PLAN
Wildlands will perform maintenance as needed on the mitigation project. A physical inspection of the
Site shall be conducted a minimum of once per year throughout the post -construction monitoring
period until performance standards are met. These site inspections may identify components and
features that require routine maintenance. Routine maintenance should be expected most often in the
first two years following construction and may include one or more of the following components.
4.1 Stream
Stream problem areas will be mapped and included in the CCPV as part of the annual stream
assessment. Stream problems areas may include bank erosion, structure failure, beaver dams,
aggradation/degradation, etc. Routine channel maintenance and repair activities may include chinking
of in -stream structures to prevent piping, securing loose coir matting, and supplemental installations of
live stakes and other target vegetation along the channel. Areas where storm water runoff flows into the
channel may also require maintenance to prevent bank failures and head -cutting.
4.2 Wetlands
Wetland problem areas will be mapped and included in the CCPV as part of the annual wetlands
assessment. Wetland problem areas may include supplemental installations of target vegetation within
the wetland. Areas where storm water and floodplain flows intercept the wetland may also require
maintenance to prevent scour. Routine wetland maintenance will be conducted and repair activities will
be implemented on an as -needed basis.
4.3 Vegetation
Vegetative problem areas will be mapped and included in the CCPV as part of the annual vegetation
assessment. Vegetation problems areas may include planted vegetation not meeting success criteria,
persistent invasive species, barren areas with little to no herbaceous cover, or grass
suffocation/crowding of planted stems. Routine vegetation maintenance and repair activities may
include supplemental planting, pruning, mulching, and fertilizing. Exotic invasive plant species shall be
controlled by mechanical and/or chemical methods. Any vegetation control requiring herbicide
application will be performed in accordance with NC Department of Agriculture (NCDA) rules and
regulations.
4.4 Site Boundary
Site boundary issues will be mapped and included in the CCPV as part of the annual visual assessment.
Site boundary issues may include mowing encroachment or boundary markers/fencing disturbed.
Routine maintenance will be conducted to address disturbed, damaged, or destroyed easement
boundary markers and will be repaired and/or replaced on an as -needed basis.

Baseline Monitoring Document and As -Built Baseline Report -FINAL 4-1
Section 5: AS -BUILT CONDITION (BASELINE)
The Site construction and as -built surveys were completed in March 2016. The survey included
developing an as -built topographic surface and locating the channel boundaries, structures, and cross-
sections. For comparison purposes, during the baseline assessments, reaches were divided into
assessment reaches in the same way that they were established for design parameters: UT1 Reaches 1
and 2, UT1A, UT1B, and UT2.
5.1 As-Built/Record Drawings
A half-size record drawing is located in Appendix 4 that includes the post -construction survey and
alignments for the project including redlines for any significant field adjustments made during
construction that were different from the design plans. Several minor adjustments were made during
construction, where needed. Specific changes along each stream are detailed below:
5.1.1 UT1 Reach 1 Upper
• The following log steps were converted to rock steps at the following stations:
o 100+47
o 100+58
o 101+50
0 101+64
0 101+70
0 101+76
0 102+20
0 103+07;
• Root Wads at Station 101+70 were replaced with Brush Toe;
• Sourwood transplants between UT1 Reach 1 Upper and UT113 were eliminated;
• An ephemeral pool was added in the left floodplain just upstream of the confluence of UTI
Reach 1 Upper and UT16; and
• Cascade structures were varied in the field based on available materials, a bed rock slide was
installed at Station 101+64 and wrapped soil lifts on banks noted in plans were eliminated.
5.1.2 UTI Reach 1 Lower
• Transplants added in the left floodplain;
• Two pilot channels were eliminated from the design in the left floodplain (see Record Drawings,
Sheet 1.2);
• Near station 105+72 the alignment was adjusted because a natural spring was found. The
alignment will differ from design in this location;
• Slight grade change made in field on left floodplain;
• Root wads were replaced with brush toe at station 110+88;
• Several log steps were replaced by rock steps along the reach (stations 106+96, 110+35, 111+63,
112+00, and 113+39); and
• A few structure changes were made per engineer's discretion/availability materials (stations
105+89, 106+76, and 110+40).
5.1.3 UTI Reach 2
• Sod mat added in several locations along UT1 Reach 2;
• A lunker log was added to the pool at Station 122+94;
Henry Fork Mitigation Site
Baseline Monitoring Document and As -Built Baseline Report -FINAL 5-1
• Log step angles were modified as needed per engineer's discretion/guidance within the reach;
• Brush toe was carried throughout pool at Station 123+77;
• Root wads at Station 125+20 were replaced with Brush Toe; and
• At the very downstream end of UT1 Reach 2 (near confluence of Henry River), the right bank
was graded back. Approximately 35 to 40 LF of boulder toe was added, along with two geolifts
to stabilize the bank.
5.1.4 UT1A
Where the ditch enters UT1A from the right hillside, a log and sod mat was added to the pool to
help prevent scour at the confluence;
Sod mat added in several locations along UT1A; and
• The 24 -inch Birch in the right floodplain near Station 185+00 was cut down.
5.1.5 UT1B
• A swale was added at the upstream end of UT1B coming from a small drainage in the right
floodplain;
• Ephemeral pool in left floodplain was eliminated during construction;
• A small rock outlet was added coming out of old Pond Bed 1 (ephemeral pool); and
• Riffle at Station 151+20 was converted from a Woody Riffle to a Constructed Riffle.
5.1.6 UT2
• Some rock was added at the upstream end of UT2 (near station 200+15);
• Brush toe was substituted for the root wad at Station 206+25;
• Sod mat added in several locations along UT2;
• Brush toe at Station 209+78 was eliminated; and
• Brush toe was added to pools at Stations 211+03 and 218+00.
5.2 Baseline Data Assessment
Baseline monitoring (MYO) was conducted between March and April 2016. The first annual monitoring
assessment (MY1) will be completed in the fall of 2016. The streams and wetlands will be monitored for
a total of seven years, with the final monitoring activities conducted in 2021. The close-out for the Site
will be conducted in 2022 given the success criteria is met. As part of the closeout process, DMS will
evaluate the Site at the end of the fourth year monitoring period to determine whether or not the Site is
eligible to closeout following monitoring year five. If the Site is meeting success criteria, DMS will
propose to the interagency review team (IRT) to proceed with the closeout process. If the Site is not
meeting success criteria, then an additional two years of monitoring will be conducted by Wildlands.
5.2.1 Morphological State of the Channel
Morphological data for the as -built profile was collected in May 2016. Please refer to Appendix 2 for
summary data tables, morphological plots, and stream photographs.
Profile and Pattern
The baseline (MYO) profiles closely match the profile design parameters. On the design profiles, riffles
were depicted as straight lines with consistent slopes. Additionally, maximum pool depths sometimes
exceed design parameters. Variations in pool depths do not constitute a problem or indicate a need for
remedial actions. The baseline (MYO) pattern metrics fell within the design parameters for all five
reaches.
Henry Fork Mitigation Site
Baseline Monitoring Document and As -Built Baseline Report -FINAL 5-2
Dimension
The baseline (MYO) dimension numbers closely match the design parameters with minor variations in all
reaches. Minor variations in both the channel depth and width are present and are a function of the
small channel size and acceptable deviation within the design range, often times resulting from sod mat
installation.
Sediment Transport
As -built shear stresses and velocities are similar to design parameters and should reduce the risk of
further erosion along the restoration reaches. The as -built condition for each of these reaches indicates
an overall increase in substrate particle size (Tables 6a and 6b). The substrate data for each constructed
reach were compared to the design shear stress parameters from the mitigation plan to assess the
potential for bed degradation. The shear stresses calculated for the constructed channels are within the
allowable range, which indicates that the channel is not at risk to trend toward channel degradation.
5.2.2 Vegetation
The baseline (MYO) planted density is 647 stems/acre, which exceeds the MY5 density requirement.
Summary data and photographs of each plot can be found in Appendix 3.
5.2.3 Stream and Wetland Hydrology
Stream and wetland hydrology being recorded on Site is currently being monitored and will be included
in the year 1 monitoring report.
