HOPPERS CREEK- MELTON CREEK STREAM RESTORATION PROJECT
YEAR 3 MONITORING REPORT
DECEMBER 2014, MONITORING YEAR 3 OF 5
1.0 EXECUTIVE SUMMARY
The Hoppers Creek - Melton Farm Restoration Project (Project) was restored by Michael Baker Engineering,
Inc. (Baker) through an on -call design and construction services contract with the North Carolina Ecosystem
Enhancement Program (NCEEP). This report documents and presents Year 3 monitoring data as required
during the five -year monitoring period.
The specific goals for the Project were as follows:
• Create geomorphically stable conditions on the Project site,
• Improve and restore hydrologic connections between the streams and their floodplains,
• Improve water quality in the South Fork Hoppers Creek watershed,
• Protect the South Fork Hoppers Creek watershed from nearby rapid development,
• Restore wetlands along South Fork Hoppers Creek in the Project area, and
• Improve aquatic and terrestrial habitat along the Project corridor.
To accomplish these goals the following objectives were implemented:
• Stabilize eroding channel banks by implementing a combination of Priority I Restoration and
Enhancement II approaches,
• Increase floodplain connectivity to restore historic floodplain wetlands,
• Incorporate bedform diversity with varied in- stream structures to provide a variety of aquatic habitats,
• Reestablish a riparian buffer with native vegetation to improve terrestrial habitat and eliminate
excessive sedimentation from erosion,
• Restore and enhance existing floodplain wetlands, where feasible, and
• Eliminate livestock access to the channel to improve water quality and reduce erosion from hoof
shear.
The Project site is located approximately 10 miles southeast of Marion in McDowell County, North Carolina,
as shown in Figure 1 in Appendix A. The Project is situated in the Catawba River Basin, within the North
Carolina Division of Water Quality (NCDWQ) sub -basin 03 -08 -30 and United States Geologic Survey
(USGS) hydrologic unit 03050101040 -020. Directions to the Project site can be found in Figure 1 of
Appendix A.
South Fork Hoppers Creek lies within the Piedmont physiographic province. Its watershed is predominately
forested, supporting some isolated rural residential housing, chicken farms, agricultural lands, nurseries, and
several small rural residential developments. The land surrounding the Project site has been used historically
for agriculture but was recently used as pasture land for livestock grazing. Some forest land is located in the
upstream extents of UT1, UT2, and UT3.
South Fork Hoppers Creek and its tributaries had been impacted by livestock and were incised and eroded.
Channel incision along South Fork Hoppers Creek resulted in the lowering of the water table; thereby,
dewatering floodplain wetlands. The Project involved the restoration or enhancement of 3,550 linear feet
(LF) of stream along South Fork Hoppers Creek, and portions of UT and UT2 using Rosgen Priority 1
restoration and Level II enhancement approaches. An additional 1,071 LF of stream along portions of UT1
and UT3 was placed in preservation. The Project also included the restoration and enhancement of 1.56 acres
of riparian wetland abutting South Fork Hoppers Creek and UT1 of which 1.23 acres comprised restoration
MICHAEL BAKER ENGINEERING, INC., EEP PROJECT NO. - 92251
HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT
YEAR 3 MONITORING REPORT
DECEMBER 2014, MONITORING YEAR 3 OF 5
and 0.33 acres comprised enhancement. The Priority 1 channel design approach entailed raising the elevation
of the channel to establish greater connectivity to the floodplain and to restore the hydrologic relationship
between South Fork Hoppers Creek, its tributaries and riparian wetland areas in the Project area. Channel
pattern was re- established to dissipate flow velocities in meander bends. In- stream habitat was created using
riffle -pool sequences and the strategic placement of in- stream structures. Approximately 5.7 acres of
associated riparian buffer were restored/enhanced throughout the Project area and a conservation easement
consisting of 10.1 acres will protect and preserve all stream reaches, wetland areas, and riparian buffers in
perpetuity.
Vegetation conditions for South Fork Hoppers Reaches 1 and 2, and UT1, Reach B were good and
performing close to 100% for both the planted acreage and invasive /encroachment area categories. Two bare
areas or vegetation problem areas (VPAs), VPA1 -1 and VPA1 -2, were documented in the wetland area
located on the right floodplain along South Fork Hoppers Reach 1. The combined total area for these WAS
was 0.12 acres, or 2.8% of the planted acreage for this assessment tract. These two WAS were identified in
the Year 1 monitoring period and carried over through Year 3. Four small areas with invasive plants were of
concern and were identified for a combined total area of 0.04 acres or 0.5% of the easement acreage. A more
detailed summary of the results for the vegetation condition assessment can be found in Appendix B which
includes a technical memorandum, current condition planview (CCPV) figures, supporting data tables, and
photo logs. The contents of Appendix B were submitted to NCEEP in May 2014 and served as the interim
visual site assessment report.
The success criteria or survival threshold of 320 stems per acre by the end of Year 3 was met for 8 out of the
12 vegetation monitoring plots. The average density of total planted stems or tract mean (including
volunteers) is 668 stems per acre. Though the majority of the Project site is on track for meeting the final
success criteria of 260 trees per acre by the end of Year 5, it should be noted that most vegetation plots
exhibiting a lower planted stem density count have been offset by the presence of thriving volunteer species.
Volunteers will continue to be included in each plot's stem count per acre throughout the monitoring period
and will likely aid in the Project's ability to meet its Year 5 final success criteria; however, additional riparian
plantings may be needed in areas where lower stem densities have been documented. Vegetation stem counts
are summarized in Tables 7 and 9 of Appendix C.
Tables 5a through 5d (Appendix B) indicate the Project site has remained geomorphically stable overall and
performing at 100% for the majority of parameters evaluated within the lateral /vertical stability and in- stream
structure performance categories. The sub - categories receiving scores of less than 100% are namely due to
small localized areas of bank scour and /or piping under structures. Stream problem areas (SPAS) correlating
with these areas of instability for the project reaches were documented and summarized in Table 5e of
Appendix B. A total of eight SPAS were identified in Year 1 and Year 2 monitoring periods and were carried
over through Year 3. No new SPAS were identified for the Year 3 assessment. A more detailed summary of
the results for the visual stream stability assessment can be found in Appendix B.
The six permanent cross - sections along the Project site show that there has been little adjustment to stream
dimension overall within the Project reach since construction. The adjustments that have occurred have
primarily been observed in riffle cross - sections that are exhibiting signs of narrowing. Based on field
observation, this narrowing can be attributed to herbaceous vegetation becoming well established over the
second year. At this time, cross- sectional measurements do not indicate any stream bank or channel stability
issues. The longitudinal profiles show that bed features are stable. Pools are well maintained, and they have
increased in depth in many areas. Grade control structures (constructed riffles, cross vanes and log sills)
continue to help maintain the overall profile desired. Visual observations and a review of pebble count data
collected during Year 3 monitoring did not yield any signs that sediment transport functions have been
hampered by the mitigation project. The pebble count data for South Fork Hoppers Creek and UT 1 B indicate
that the stream is moving fines through the system and larger pebbles are making up a greater percentage of

the bed material. The site was found to have had at least one bankfull event based on crest gauge readings.
Information on these events is provided in Table 12 of Appendix E.
Based on the third growing season following site construction (March 30, 2013 - November 2, 2013), all four
wetland areas met the success criteria for Monitoring Year 3. Groundwater conditions at all Gauges indicated
saturated conditions existed for 100% of the growing season. A summary plot of wetland gauge data as it
relates to monthly precipitation is provided in Figure 7 of Appendix E; wetland areas and corresponding
gauges are illustrated in the CCPV sheets (Figure2) in Appendix B.
Summary information/data related to the occurrence of items such as beaver or encroachment, and statistics
related to 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 Baseline Monitoring Report (formerly Mitigation Plan) and in the Mitigation Plan (formerly
Restoration Plan) documents available on EEP's website. It should be noted that the Baseline Monitoring
Report and Mitigation Plan for this Project site is included with the summary of constructed design
approaches for the South Muddy Creek Restoration Project (EEP Project No. 737), a nearby project site that
was designed and constructed in conjunction with the Hoppers Creek - Melton Farm Stream Restoration
Project as part of the same EEP on -call design and construction services contract. All raw data supporting
the tables and figures in the appendices is available from EEP upon request.
2.0 METHODOLOGY
The five -year monitoring plan for the Project site includes criteria to evaluate the success of the vegetation,
stream, and wetland components of the project. The methodology and report template used to evaluate these
three components adheres to the EEP monitoring guidance document dated November 7, 2011, which will
continue to serve as the template for subsequent monitoring years. The specific locations of monitoring
features, such as vegetation plots, permanent cross - sections, reference photo stations and wetland/crest
gauges, are shown on the CCPV sheets found in Figure 2 of Appendix B.
The majority of Year 3 monitoring data was collected in May 2014 and August 2014. All visual site
assessment data was collected on April 16, 2014. Vegetation monitoring plot data was collected on
November 4, 2014. All stream survey (channel dimension and profile) and sediment data were collected
September 4, 2014. Stream survey data was collected using a Topcon GRS -1 network Rover GPS unit which
collects point data with an accuracy of less than one tenth of a foot.
2.1 Stream Assessment
Geomorphic monitoring of restored stream reaches is being conducted for five years to evaluate the
effectiveness of the restoration practices installed. Monitored stream parameters include channel dimension
(cross- sections), profile (longitudinal survey), bed composition, bank and channel stability, bankfull flows,
and reference sites documented by photographs. A crest gauge, as well as high flow marks, will be used to
document the occurrence of bankfull events. The methods used and any related success criteria are described
below for each parameter. For monitoring stream success criteria, 6 permanent cross - sections, 1 crest gauge,
and 39 photo identification points were installed.

HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT
YEAR 3 MONITORING REPORT
DECEMBER 2014, MONITORING YEAR 3 OF 5
2.1.1 Morphologic Parameters and Channel Stability
2.1.1.1 Dimension
Six permanent cross - sections were installed throughout the entire project area. Cross- sections
selected for monitoring were located in representative riffle and pool facets and each cross - section
was marked on both banks with permanent pins to establish the exact transect used. Each of the three
restored Project reaches, Reaches 1 and 2 of South Fork Hoppers Creek and UT1B, contains one riffle
and one pool cross - section. A common benchmark is being used for cross - sections and consistently
referenced to facilitate comparison of year -to -year data. The cross - sectional surveys will include
points measured at major breaks in slope, including top of bank, bankfull, inner berm, edge of water,
and thalweg, if the features are present. Riffle cross- sections were classified using the Rosgen Stream
Classification System ( Rosgen, 1994), and all monitored cross - sections should fall within the
quantitative parameters defined for channels of the design stream type.
There should be little change in as -built cross - sections. If changes do take place, they will be
evaluated to determine if they represent a movement toward a more unstable condition (e.g., down -
cutting or erosion) or a movement toward increased stability (e.g., settling, vegetative changes,
deposition along the banks, or decrease in width/depth ratio). Cross - sectional data is presented in
Figure 3 of Appendix D.
2.1.1.2 Longitudinal Profile
Longitudinal profiles were surveyed for the entire restored lengths of Reaches 1 and 2 of South Fork
Hoppers Creek and UT113, and are provided in Figure 4 of Appendix D. Longitudinal profiles will be
replicated annually during the five year monitoring period.
Measurements taken during longitudinal profiles include thalweg, water surface, and the top of low
bank. All measurements were taken at the head of each feature (e.g., riffle, run, pool, glide) and the
maximum pool depth. Elevations of grade control structures were also included in the longitudinal
profiles surveyed. Surveys were tied to a permanent benchmark.
The pools should remain relatively deep with flat water surface slopes, and the riffles should remain
steeper and shallower than the pools. Bed form observations should be consistent with those
observed for channels of the design stream type as well as other design information.
2.1.1.3 Substrate and Sediment Transport
Bed load material analysis consists of a pebble count taken in the same constructed riffle during
annual geomorphic surveys of the Project site. One sample was collected at the riffle cross - section
corresponding with each of the three restored Project reaches for a total of three sediment samples
(cross- sections X5, X7, X9). These samples, combined with evidence provided by changes in cross -
section and profile data will reveal changes in sediment gradation that occur over time as the stream
adjusts to upstream sediment loads. Significant changes in sediment gradation will be evaluated with
respect to stream stability and watershed changes. Bed material distribution data are located in Figure
5 of Appendix D.
2.1.2 Hydrology
2.1.2.1 Streams
The occurrence of bankfull events within the monitoring period will be documented by the use of
crest gauges and photographs. One crest gauge was installed on the floodplain at the bankfull
elevation along the right top of bank at station 15 +10. The bottom of the crest gauge coincides with
the top of bank (bankfull) elevation. The crest gauges record the highest watermark between site
visits, and are checked at each site visit to determine if a bankfull event has occurred. Photographs

are used to document the occurrence of debris lines and sediment deposition on the floodplain during
monitoring site visits.
Two bankfull flow events must be documented at the crest gauge within the 5 -year monitoring period.
The two bankfull events must occur in separate years; otherwise, the stream monitoring will continue
until two bankfull events have been documented in separate years or until the monitoring period ends.
If two bankfull events have not been documented at the end of 5 years the Interagency Review Team
(IRT) will have to decide on an appropriate course of action.
2.1.3 Photographic Documentation of Site
Photographs will be used to document restoration success visually. Reference stations were photographed
during the as -built survey; this will be repeated for at least five years following construction. Reference
photos are taken once a year, from a height of approximately five to six feet. Permanent markers will
ensure that the same locations (and view directions) are utilized during each monitoring period. Selected
site photographs are shown in Appendix B.
2.1.3.1 Lateral Reference Photos
Reference photo transects were taken of the right and left banks at each permanent cross - section. A
survey tape was captured in most photographs which represents the cross - section line located
perpendicular to the channel flow. The water line was located in the lower edge of the frame in order
to document bank and riparian conditions. Photographers will make an effort to consistently maintain
the same area in each photo over time.
2.1.3.2 Structure Photos
Photographs of primary grade control structures (i.e. vanes and weirs), along the restored streams are
included within the photographs taken at reference photo stations. Photographers will make every
effort to consistently maintain the same area in each photo over time.
Lateral and structure photographs are used to evaluate channel aggradation or degradation, bank erosion,
success of riparian vegetation, structure function, and stability, and effectiveness of erosion control measures
subjectively. Lateral photos should not indicate excessive erosion or degradation of the banks. A series of
photos over time should indicate successive maturation of riparian vegetation and consistent structure
function.
2.1.4 Visual Stream Morphological Stability Assessment
The visual stream morphological stability assessment involves the qualitative evaluation of lateral and vertical
channel stability, and the integrity and overall performance of in- stream structures throughout the Project
reach as a whole. Habitat parameters, such as riffle embeddedness and pool depth maintenance, are also
measured and scored. The entire project reach was walked, noting geomorphic conditions of the stream bed
profile (riffle /pool facets), both stream banks, and engineered in- stream structures. Photos were taken at
every stream photo reference station as discussed in the previous section, and in locations of potential SPAS
which were documented in the field for subsequent mapping on the CCPV figures. A more detailed summary
of the methodology and results for the visual stream stability assessment can be found in Appendix B which
includes a technical memorandum, supporting data tables, and SPA photos.
2.2 Vegetation Assessment
Successful restoration of the vegetation on a mitigation site is dependent upon hydrologic restoration, active
planting of preferred canopy species, and volunteer regeneration of the native plant community. In order to
determine if the criteria are achieved, twelve vegetation monitoring quadrants were installed across the
Project site, which included one wetland vegetation plot. The total number of quadrants was calculated using
MICHAEL BAKER ENGINEERING, INC., EEP PROJECT NO. - 92251
HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT
YEAR 3 MONITORING REPORT
DECEMBER 2014, MONITORING YEAR 3 OF 5
the CVS -NCEEP Entry Tool Database version 2.2.7 (CVS - NCEEP, 2007). The size of individual quadrants
varies from 100- square meters for tree species to 1- square meter for herbaceous vegetation. Level 1 CVS
vegetation monitoring will occur in spring, after leaf -out has occurred, or in the fall prior to leaf fall. At the
end of the first growing season during baseline surveys, species composition, density, and survival were
evaluated. Individual quadrant data provided during subsequent monitoring events will include diameter,
height, density, and coverage quantities. Relative values will be calculated, and importance values will be
determined. Individual seedlings will be marked to ensure that they can be found in succeeding monitoring
years. Mortality will be determined from the difference between the previous year's living, planted seedlings
and the current year's living, planted seedlings.
The interim measure of vegetative success for the site is the survival of at least 320, 3 -year old, planted trees
per acre at the end of Year 3 of the monitoring period. The final vegetative success criteria is the survival of
260, 5 -year old, planted trees per acre at the end of Year 5 of the monitoring period.
Photographs are used to visually document vegetation success in sample plots. Reference photos of tree and
herbaceous condition within plots are taken at least once per year. As part of the visual site assessment
conducted on April 16, 2014, the vegetation condition of planted vegetation along stream banks, floodplains
(wetlands), and terraces were qualitatively evaluated for performance; this also included the documentation of
invasive species and potential WAS which were recorded in the field for subsequent mapping on the CCPV
figures. A more detailed summary of the methodology and results for the vegetation condition assessment
can be found in Appendix B which includes a technical memorandum, supporting data tables, and photo logs.
2.3 Wetland Assessment
Four groundwater monitoring stations were installed in restored/enhanced wetland areas to document
hydrologic conditions at the Project site. These four wetland gauges are depicted on the CCPV figures found
in Appendix B. Installation and monitoring of the groundwater stations have been conducted in accordance
with the USACE standard methods outlined in WRP Technical Notes ERDC TN- WRAP -00 -02 (July 2000).
Precipitation data from a nearby meteorological station (NC -MD -2) will also be downloaded annually for the
five years of groundwater monitoring conducted post - construction; this station is located in close proximity to
Marion, NC. This data will be obtained from the State's Climate Office website (CRONOS 2012).
Baker used DRAINMOD (Version 5.1) to develop hydrologic simulation models that represented conditions
at a variety of locations across the Project site. DRAINMOD indicated wetland hydrology would occur for
approximately 6 -12% of the growing season. Based on these findings, it was determined that success criteria
for wetland hydrology will be met when each wetland site is saturated within 12 inches of the soil surface for
at least 9% of the growing season, or 19 consecutive days.

PROGRAM
Year 3 Site Assessment Report — S. Fork Hoppers Creek North Carolina Ecosystem Enhancement Program
Michael Baker Engineering, Inc. May 31, 2014
Pagel of 8
1. Introduction
1.1 Purpose
This report summarizes overall stream and vegetation conditions as part of an interim site
assessment conducted in conjunction with the Year 3 monitoring services for the Hoppers
Creek - Melton Farm Stream Restoration Project site located in McDowell County, NC. This
site assessment will be included as part of a more comprehensive annual monitoring report to
be completed and submitted later this year (fall 2014). The report describes project
objectives, discusses the assessment methodology, summarizes assessment results, and
documents potential stream and vegetation problem areas (SPAs and VPAs respectively).
1.2 Objectives
The objectives of the site assessment were to:
• provide a general overview of stream morphological stability;
• provide a general overview of vegetation conditions;
• identify and document potential SPAs and VPAs.
1.3 Supporting Data
Supporting data and inform ation are p rovided following the na rrative portion of this rep ort
and include:
• current condition plan view (CCPV) figures (Figure 2, sheets 1 through 3);
• visual stream morphology stability assessment table (Tables 5a through 5d);
• SPA inventory table (Table 5e);
• vegetation condition assessment table (Tables 6a and 6b);
• VPA inventory table (Table 6c);
• stream station photos;
• SPA photos;
• VPA photos.
2 Methodology
The methodology used for assessing overall stream and vegetation conditions at the Hoppers
Creek - Melton Farm Stream Restoration Project site adhered to the most recent NCEEP
monitoring guidance documents (dated November 7, 2011). The site assessment was
comprised of two components, a visual stream morphology stability assessment and a
vegetation condition assessment, both of which are described in more detail in the following
sections of this report. The assessment was strictly qualitative. Vegetation monitoring plot
counts were excluded from this assessment but will be conducted after July 2014; this data
Year 3 Site Assessment Report — S. Fork Hoppers Creek North Carolina Ecosystem Enhancement Program
Michael Baker Engineering, Inc. May 31, 2014
Page 2 of 8
will be summarized in Appendix C and the CCPV figure of the Year 3 annual monitoring
report to be submitted in late November of this year.
The Hoppers Creek - Melton Farm Stream Restoration Project site was evaluated as four
separate project reaches for the visual stream morphology stability assessment as they were
for the Final Baseline Monitoring Document /As -Built Report: South Fork Hoppers Creek
(SFHC) Reaches 1 and 2, UT Reach B, and UT2 (Reaches A and B). SFHC Reaches 1 and
2 are delineated by the confluence of UT Reach B where SFHC Reach 1 is located upstream
of the confluence and SFHC Reach 2 is located downstream of the confluence. UT2 Reach
A extends from the upstream limits located within the conservation easement boundary to the
downstream limits of the constructed step -pool channel, and UT2 Reach B includes the
remaining corridor located downstream of the step -pool charnel until its confluence with
SFHC Reach 1.
Due to expected performance issues related to the persistence of invasive species on UT2
(Reaches A and B), vegetation conditions for it were assessed independently from the
remainder of the Hoppers Creek - Melton Farm Stream Restoration Project site which
exhibited uniform conditions, and thus resulted in two distinct vegetation assessment tracts.
Vegetation conditions for both tracts are reported in Tables 6a and 6b. Baker performed the
visual site assessment on April 16, 2014.
2.1 Visual Stream Morphology Stability Assessment
The visual stream morphology stability assessment involved the evaluation of lateral and
vertical channel stability, and the integrity and overall performance of in- stream structures
throughout each of the four project stream reaches. Habitat parameters, such as riffle
embeddedness and pool depth maintenance, were also measured and scored. Each stream
reach was walked, noting geomorphic conditions of the stream bed profile (riffle /pool facets),
both stream banks, and engineered in- stream structures. Photos were taken at every existing
stream photo point (from the as- built) and in locations of potential SPAs which were
recorded in the field for subsequent mapping on the CCPV figures.
2.2 Vegetation Condition Assessment
The vegetation condition assessment involved the evaluation of vegetation within the 10.1
acre conservation easement and included assessing the performance of planted vegetation
along stream banks, floodplains, and terraces as well as the documentation of invasive
species. The assessment of planted vegetation was confined to the 5.7 acres of riparian
buffer planting zones located within the easement boundary as part of the restoration design;
whereas, invasive vegetation and encroachment areas of invasive species were evaluated for
the entire 10.1 acre easement boundary. Photos were recorded in locations of potential VPAs
throughout the easement, such as areas exhibiting sparse or slow growth/vigor, low stem
density, and invasive areas of concern.

2.3 Post - processing of Field Data
The post - processing of field data consisted of the download and organization of photos into
respective photo logs (stream and vegetation), creating the CCPV figures in GIS and
AutoCAD using the field- mapped SPAS and VPAs, populating the SPA and VPA tables, and
finally scoring the performance of the four stream reaches and two vegetation tracts in terms
of stream morphological stability and vegetation condition using assessment forms provided
by NCEEP.
3 Summary of Results
3.1 Visual Stream Morphology Stability Assessment
Tables 5a through 5d summarize the performance of each of the four project stream reaches
mentioned above for the Hoppers Creek - Melton Farm Stream Restoration Project in terms of
lateral (stream bank) and vertical (channel bed) stability while evaluating the functionality
and integrity of in- stream structures. Engineered in- stream structures evaluated for the
assessment of this project reach consisted of constructed riffles, log sills (drops), cross vanes,
log vanes, root wads, geolifts, and brush mattresses. Constructed riffles were justified for
inclusion in the evaluation of structures since they are the predominant grade control
structure used throughout the site; however, they were only assessed for the `overall
integrity' and `grade control' parameter categories in Tables 5a through 5d.
As Tables 5a through 5d indicate, the Hoppers Creek - Melton Farm Stream Restoration
Project site was geomorphically stable overall and performing at 100 percent as the design
intended for the majority of parameters evaluated within the lateral /vertical stability and in-
stream structure performance categories. UT1 Reach B was functioning at the highest level
geomorphically out of all the stream project reaches, performing at 100 percent for all sub-
categories except for `Riffle Condition' —two riffles located within the upstream project
limits (at stations 10 +00 and 12 +00) were covered in fines from an upstream sediment source
but the coarse riffle substrate appeared intact beneath the fines. SFHC Reach 1 received the
lowest performance scores (for all 3 major morphological channel categories) in terms of
lateral, vertical, and in- stream structural stability out of all the project stream reaches
followed by SFHC Reach 2 and UT2 (Reaches A and B). SFHC Reaches 1 and 2, and UT2
(Reaches A and B) had more than one sub - category receiving scores of less than 100 percent
namely due to one or more of the following issues: localized areas of lateral instability or
bank erosion from bank scour and bank slumping, and the piping or failure of engineered in-
stream structures; SPAS correlating with these issues for these three project reaches were
documented and summarized in Table 5e.
There were a total of 8 SPAS documented, 4 of which were identified during the Year 1
visual assessment and 4 that were identified during the Year 2 assessment. No new SPAs
were identified for the Year 3 assessment. SPAs documented in previous years were
included in this assessment since they have persisted to date.

The first number in the SPA naming convention (in Table 5e) references the monitoring year
in which the SPA was identified during the visual assessment. A brief description of the
SPAs reported from previous year's assessment is discussed below. The SPAS have
remained unchanged in condition and scale when observed during this assessment, but they
still remain problem areas and should be monitored. All are included in the scoring of
morphological performance categories in Tables 5a through 5d, and are also summarized in
Table 5e, Figure 2 (CCPV), and the SPA photolog.
Two SPAS identified in previous years (SPA 1 -3 and SPA2 -5) have been removed from the
SPA list. These two areas consisted of in stream structures that were exhibiting piping.
SPA 1 -3 involved piping through both vane arms and under the second sill of a boulder cross
vane at station 19 +23 on SFHC Reach 2. SPA2 -5 involved piping under a log sill at station
12 +90 on UT2 Reach A. Both structures have been successfully repaired and are functioning
correctly.
SPA 1 -1 and SPA 1 -2 are characterized by small localized areas of bank scour and are located
across the channel from one another on SFHC Reach 1; SPA 1 -1 is located along the left bank
and SPA 1 -2 is located along the right bank a little further downstream. The invert along
these two sills are sloped to one side (slanted) and oriented within the channel such that flow
is being directed toward the bank immediately downstream of where the log sill ties into the
bank, causing bank erosion. Banks of both SPAS are vertical and exposed, and warrant
stabilizing to prevent the spread of lateral instability further downstream.
SPA1 -5 consists of the piping of flow through a log sill structure in UT2 Reach A. The
structure is vertically and laterally stable and should seal over time.
The heavily armored, ephemeral drainage located near the upstream extents of UT2 Reach A
was inspected for overall structural integrity and stability even though the short reach is not
being sought for mitigation credit. Upon inspection, the channel bed of the downstream riffle
cascade had eroded (SPAT -6). Coarse riprap material has been deposited downstream atop
the lowest elevation boulder sill, exposing the underlying filter fabric as a result.
SPA2 -1 and SPA2 -2 are located in close proximity to each other on opposite banks
downstream of a meander bend between stations 15 +95 and 16 +32 on SFHC Reach 1.
SPA2 -1 is characterized by a failing rootwad associated with the erosion and undercutting of
the left bank located immediately downstream of a log sill around station 16 +25. The invert
along the upstream log sill is sloped to one side (slanted toward the left bank) and is oriented
within the channel such that flow is being directed toward the left bank immediately
downstream of where the log sill ties into the bank, causing bank erosion. Erosion along the
left bank appears to have migrated further downstream over time, scouring the upstream
portion of the rootwad and the channel toe beneath it, eventually undermining the structure.
The rootwad has separated from the left bank, has slumped into the channel, and is no longer
affording erosion protection of the left bank.
SPA2 -2 is located across the channel and just upstream from SPA2 -1 on the right bank, and
consists of a slumping bank situated along the downstream portion of an outer meander bend.
Year 3 Site Assessment Report — S. Fork Hoppers Creek North Carolina Ecosystem Enhancement Program
Michael Baker Engineering, Inc. May 31, 2014
Page 5 of 8
The 15 LF section of calved right bank has separated but not yet slumped into the channel.
Flow behind the separated bank threatens to continue to erode and expose the parent bank
which is vertical and devoid of stabilizing vegetation. Bank slumping of SPA2 -2 may be a
result of poor soil compaction during construction and /or the unconsolidated nature of the
soil matrix within the bank, which without adequate vegetation to help reinforce or stabilize
the bank is easily eroded. This is evident as the mass wasting along the right bank extends
about 15 LF downstream along one continuous fissure to the log sill associated with SPA2 -1.
The tie -in of the log sill along the right bank around station 16 +10 is slightly exposed as a
result; the sill appears to be fully functional as grade control, but may become structurally
compromised if scour behind the slumped bank material extends over time.
SPA2 -3 involves localized scour along the left bank of a riffle located upstream of the
easement crossing between stations 18 +75 and 18 +87. Flow has scoured out and eroded a
small portion of the left bank behind a cluster of well rooted, native vegetation that is thriving
at the bank. The vegetation is comprised primarily of Willow Oak, Tag Alder, and Soft
Rush. Matting along the bank is generally intact but has separated from the bank in areas due
to erosion over time that has caused the bank to recede. The left bank is vertical, exposed,
and devoid of vegetation resulting in no surface protection. The thalweg along the riffle
where SPA2 -3 is located appears to be centered; but velocity vectors, and thus flow, may
have been temporarily redirected toward the left bank during past storm events from slight
temporal shifts in aggraded riffle material within the riffle, thereby increasing stress along the
left bank making the bank more susceptible to subsequent erosion.
SPA24 is located on UT2 Reach B and is a steep portion of left bank located across from
vegetation plot 13 that is slumping and separating from the top of terrace. This bank was
originally stabilized during construction by a combination of bank grading,
temporary /permanent seeding, the installation of staked matting, and the planting of live -
stake vegetation. The graded bank began to slump before construction was completed and
was re- stabilized before demobilization and project closeout. The cause of the recurrent bank
instability at SPA24 may potentially be a result of poor soil compaction and overland storm
flow seepage that appears to be occurring at the top of terrace which may be undermining the
re- graded bank.
SPA2 -5 consists of the piping of flow through a riffle cascade (log sill) structure at station
12 +90 in UT2 Reach A. The structure is vertically and laterally stable. Some water was
observed flowing over the log sill invert; the log sill should re -seal over time.
Log sills associated with deep scour pools on UT1 Reach B were inspected and assessed for
vertical stability per EEP's request during the Year 2 assessment and reassessed during the
Year 3 assessment. EEP's concern was that the depth of some of these scour pools could
potentially pose a threat and undermine the structural integrity and grade control function to
their upstream log sill counterpart considering the small channel dimensions associated with
this stream reach. Pools for UT Reach B were designed to have a maximum pool depth
(d,,I) ranging between 1.0 and 2.0 feet and a ratio of pool depth to average bankfull depth
(d,001/dbkf) ranging between 2.0 and 4.0 (as cited in Table 7.2 from the South Muddy Creek
Stream Restoration Plan). EEP's monitoring guidance (dated November 7, 2011) for
Year 3 Site Assessment Report — S. Fork Hoppers Creek North Carolina Ecosystem Enhancement Program
Michael Baker Engineering, Inc. May 31, 2014
Page 6 of 8
defining `sufficient depth' for meander pool condition suggests that a pool should have a
dpoo, /dbkf ratio greater than or equal to 1. 6, which in this case for UT 1 Reach B translates to a
dPoo, of 0.8 feet in depth or greater. All log sill scour pools on UT 1 Reach B had dPoo, /dbkf
ratios exceeding 1.6 and thus fulfilled EEP's monitoring guidance criteria for sufficient depth
for meander pool condition for this current visual morphological assessment. The deepest of
these pools were those three log sill scour pools located downstream of the easement crossing
between stations 19 +00 and 19 +50. The upstream most log sill remains the deepest of the
three and had a dpoo, value and dpoo, /dbkf ratio of 2.2 feet and 4.4 respectively. This marks a
slight decrease in dpoo, value and dpoo, /dbkf ratio of 2.5 feet and 5.0 recorded in the Year 2
Assessment. Even though the dpoo, value of 2.2 feet exceeds that specified for the proposed
design (by 0.2 feet), it still meets EEP's monitoring guidance criteria for the assessment.
These log sill structures were constructed with a header and footer log. The footer log at this
particular log sill was still buried below the elevation of the scour pool, affording protection
from undermining and helping to hold the entire structure firmly in place. Like other pools
throughout the project site, the depth of this pool should fluctuate and fill in with sediment
over time in between storm events. These log sills /scour pools will continue to be monitored
in subsequent years.
3.2 Vegetation Condition Assessment
Tables 6a and 6b summarize the vegetation conditions of the Hoppers Creek - Melton Farm
Stream Restoration site. Table 6a references the vegetation assessment tract associated with
SFHC Reaches 1 and 2, and UT Reach B; Table 6b references the vegetation assessment
tract associated with UT2 (Reaches A and B). There were a total of 6 VPAs, 2 of which were
identified during the Year 1 visual assessment and 4 that were identified during the Year 2
assessment. Bare floodplain conditions account for 2 of the VPAs, and the presence of
invasive species accounts for the remaining 4 VPAs. A NCEEP licensed contractor
conducted exotic invasive plant control over nine days between June 20 and August 14, 2013.
This treatment was effective in reducing the total number of VPAs from 10 in Year 2 to 6 in
Year 3. As a result of the treatment, no new VPAs were identified in the Year 3 assessment.
The VPAs remaining as a result of invasive species show signs of treatment and are less
dense though some re- sprouting has occurred. As with the SPAS, the first number in the
VPA naming convention references the monitoring year in which the VPA was identified
during the visual assessment. A brief description of the VPAs reported from previous year's
assessment is discussed below. All VPAs are included in the scoring of easement acreage
performance categories in Tables 6a and 6b, and are also summarized in Table 6c, Figure 2
(CCPV), and the VPA photolog.
VPA 1 -1 and VPA 1 -2 are the two bare areas that were documented in the wetland area
located in the right floodplain along SFHC Reach 1. The combined total area for these VPAs
is 0.12 acres, or 2.8% of the planted area acreage for this assessment tract. The two VPAs
have remained somewhat bare since construction was completed. This could possibly be due
to standing water from frequent inundation and/or the washing away of dispersed seeds by
frequent overbank flows.

Page 7 of 8
VPA2 -2 is a small area of invasive species located on the left floodplain of SFHC Reach 2.
The primary invasive is multiflora rose (Rosa multiflora) and privet (Ligustrum sinense).
VPA2 -2 appears to have been caused by a combination of invasives persisting after treatment
and from intact seed sources contained within the existing tree stand in which VPA2 -2 is
situated. The three VPAs reported within UT Reach B (VPA2 -2, VPA2 -5, and VPA2 -6) are
all located in the right floodplain or terrace and are composed primarily of multiflora rose
(Rosa multiflora) that seems to have persisted after prior treatment. VPA2 -4 is located on the
eastern periphery of vegetation monitoring plot 22 and may have proliferated from seed
sources contained within the existing tree stand located just outside the vegetation plot. The
combined total area for these 4 VPAs is 0.04 acres, or 0.5% of the planted area acreage for
this assessment tract.
