JANUARY 2017, MONITORING YEAR 3 OF 7
1.0 EXECUTIVE SUMMARY
Michael Baker Engineering, Inc. (Baker) restored 3,274 linear feet (LF) of perennial and intermittent stream,
2.8 acres (AC) of riparian wetlands, and planted 17.5 acres (AC) of native riparian vegetation within the entire
conservation easement along two unnamed tributaries (UT2 and UT3) to St. Clair Creek in Beaufort County,
North Carolina (NC) (Figure 1). The St. Clair Creek Restoration Project (Site) is located in Beaufort County,
approximately five miles east of the Town of Bath. The Site is located in the NC Division of Water Resources
(NCDWR) subbasin 03-03-07 and the NC Department of Environmental Quality (NC DEQ) Division of
Mitigation Services (DMS) Targeted Local Watershed (TLW) 03020104-040040 of the Tar -Pamlico River
Basin. The project involved the restoration of a Coastal Plain Headwater Small Stream Swamp system (NC
WAM 2010, Schafale and Weakley 1990) from impairments within the project area due to past agricultural
conversion and silviculture.
The primary restoration goals of the project were to improve ecological functions to the impaired areas within
the Tar -Pamlico River Basin as described below:
• Create geomorphically stable conditions along the unnamed tributaries across the project,
• Implement agricultural BMPs to reduce nonpoint source inputs to the downstream estuary,
• Protect and improve water quality by reducing nutrient and sediment inputs,
• Restore stream and wetland hydrology by connecting historic flow paths and promoting natural flood
processes, and
• Restore and protect riparian buffer functions and corridor habitat in perpetuity by establishing a
permanent conservation easement.
To accomplish these goals, the following objectives were identified:
• Restore existing channelized streams by restoring the relic headwater valley and allowing diffuse flow,
providing the streams access to their floodplains,
• Increase aquatic habitat value by allowing natural microtopography to form,
• Plant native species riparian buffer vegetation within the headwater valley and floodplain areas, and
within the wetland areas, protected by a permanent conservation easement, to increase stormwater
runoff filtering capacity, decrease erosion, and shade the stream to decrease water temperature,
• Improve aquatic and terrestrial habitat through improved substrate and in -stream cover, addition of
woody debris, and reduction of water temperature, and
• Control invasive species vegetation within the project area and if necessary continue treatments during
the monitoring period.
During Year 3 monitoring, the planted acreage performance categories were functioning at 100 percent with no
bare areas or low stem density areas to report. The average density of total planted stems, based on data
collected from the nine monitoring plots during Year 3 monitoring, is 607 stems per acre. The Year 3 data
demonstrate that the Site has met the minimum success interim criteria of 320 trees per acre by the end of Year
3.
Following Year 2 monitoring, Pinus taeda (loblolly pine) was documented in the area of UT2. The loblolly
pines were short but had the potential to pose a future threat to the survival of planted species installed during
the construction phase. To prevent this nuisance species from affecting the planted stems, a thinning and

ST. CLAIR CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 95015
JANUARY 2017. MONITORING YEAR 3 OF 7
removal effort took place in March 2016, which targeted the loblolly pine. The methods used were hand/power
tools and chemical applications.
Additionally, during the fall of Year 3 monitoring, loblolly pine was still documented in the area of UT2 as well
as the UT3 area. The loblolly pines are dispersed across both reaches of the site. This nuisance species still
has the potential to pose a future threat to the survival of planted species installed during the construction phase.
Additional treatment of the loblolly pines are once again planned for treatment in during Year 4/2017. The
methods to be used for treatment will again be hand/power tools and chemical applications.
In the fall of 2015, the restoration site landowner cut a network of drainage ditches adjacent to the easement
boundaries of both UT2 and UT3 (shown as dashed green lines on Figure 3). The landowner implemented a
plan to re -cut pre-existing lateral drainage ditches that joined a new deeper ditch that directly abuts the Site's
conservation easements. These new ditches were cut on the eastern and western boundary of UT2 as well as
the western boundary of UT3. The landowner cut the ditches with the intent to drain water away from his pine
plantation that abuts both easement boundaries on the west and east. Additionally, the property and farm access
road that lies to the north of the Site was also retaining water and needed to drain across the northern road into
the conservation easement to prevent hydrologic trespass.
To remedy this ditching impact as described above, a proposed work plan described in Section 2.2.1 took place
in three different locations: (1) The northern conservation easement boundary of UT 2 along the existing farm
road, (2) the western conservation easement boundary of UT2 along the wetland restoration area, and (3) along
the western conservation easement boundary of UT3 along the wetland restoration area.
To provide additional groundwater data during the monitoring period, four new monitoring wells were installed
in April 2016, which is approximately 2 months after the beginning of the growing season. These four
additional wells are providing additional wetland success data, as well as collecting groundwater levels adjacent
to the areas where the additional ditching repairs took place. These four new wells were installed as shown in
Figure 2.
Year 3 wetland groundwater monitoring demonstrated that 2 of 8 groundwater monitoring wells located along
UT2 and UT3 exhibited water levels within 12 inches of the ground surface that was greater than 12 percent of
the growing season. The eight on-site wetland monitoring wells demonstrated consecutive hydroperiods, which
ranged from 3.9 to 13.1 percent of the growing season. The growing season for Beaufort County is from
February 28 to December 6 (282 days). Additionally, during Year 3 monitoring, the on-site wetland reference
wells, which are on the downstream portions of UT3, demonstrated consecutive hydroperiods, which ranged
from 40.9 to 43.8percent of the growing season. It should be noted that the placement of the reference wells is
further down valley then the monitoring wells and is more heavily influenced by backwater from St. Clair
Creek.
On-site flow through the restored headwater valleys of UT2 and UT3 was recorded throughout 2016 by the use
of pressure transducers. All six flow gauges installed on the Site recorded flow in 2016. The flow gauges
documented flow through the headwater valleys during Year 3, which ranged from 45.6 to 85.7 consecutive
days. It is noted that the flow gauges demonstrated similar flow events relative to rainfall events on site as
demonstrated in the gauge graphs in Appendix D.
In addition, currently contracted riparian buffer credits have been included as part of the project as referenced
by the "Site Viability for Buffer Mitigation" memo from Karen Higgins (NCDWR) dated January 7, 2016 and
included as an asset in this report. As part of the St. Clair Creek Restoration project, Riparian Buffer credits in
excess of the contracted 6.8 acres (296,208 square feet) will be provided. Monitoring for success of riparian
buffers will continue to follow the existing vegetation monitoring protocol and success criteria as stated in the
approved mitigation plan for stream and wetland vegetation success. No additional vegetation monitoring plots

JANUARY 2017. MONITORING YEAR 3 OF 7
are required to monitor buffer success as the existing monitoring plots serve to monitor the success of the
vegetation of the headwater coastal plain stream and the riparian buffer.
Summary information/data related to the Site 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 and in
the Mitigation Plan available on the North Carolina Division of Mitigation Services (NCDMS) website. All
raw data supporting the tables and figures in the Appendices are available from NCDMS upon request.
2.0 METHODOLOGY
The seven-year monitoring plan for the Site includes criteria to evaluate the success of the stream, wetland and
vegetation components of the project. The methodology and report template used to evaluate these components
adheres to the NCDMS 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, flow gauges and wells are shown on the CCPV sheets found in Appendix B.
Since the growing season for the Beaufort County ends on December 6t'', the Year 3 well and flow data were
collected December 2016. All visual site assessment data contained in Appendix B were collected in October
and 2016.
2.1 Stream Assessment — Reaches UT2 and UT3
The UT2 and UT3 mitigation approach involved the restoration of historic flow patterns and flooding functions
in a multi -thread headwater stream system, monitoring efforts will focus on visual observations to document
stability and the use of water level monitoring gauges to document saturation and flooding functions. The
methods used and any related success criteria are described below for each parameter. Monitoring efforts focus
on visual observations and in -channel flow gauges/pressure transducers to document stream success.
As -built Stream survey data was collected to a minimum of Class C Vertical and Class A Horizontal Accuracy
using Leica TS06 Total Station and was georeferenced to the NAD83 State Plane Coordinate System, FIPS3200
in US Survey Feet, which was derived from the As -built Survey. This survey system collects point data with
an accuracy of less than one tenth of a foot.
2.1.1 Hydrology
Total observed area rainfall for the period of January 2016 through November 2016 was 44.91 inches,
as compared to the Beaufort County WETS table for the same period of 46.68 inches annually.
Four automated flow gauges (pressure transducers) were installed in the UT2 channel as well as two
flow gauges installed in the UT3 channel. The gauges were installed approximately 500 feet apart
within the restored systems to document flow duration. Success criteria are considered to have been
met if 30 consecutive days of flow were observed at any point during the monitoring year. Results
indicate that all six flow gauges met the minimum consecutive days of surface flow required for success
during Year 3. The complete flow data and observed rainfall graphs for each gauge, along with the
flow gauge success summary Table 11 are located in Appendix D.

2.1.2 Photographic Documentation
The reaches were photographed longitudinally beginning at the downstream end of both reaches,
moving upstream to the beginning of each reach. Photographs were taken looking upstream at
delineated locations throughout the restored stream valley. Points were close enough together to
provide an overall view of the reach lengths and valley crenulations. Photographs of photo points,
wetland wells, and flow gauges are located in Appendix B.
2.2 Wetland Assessment
Wetland monitoring is assessed by the use of eight automated groundwater -monitoring stations that are installed
following construction in the UT2 and UT3 wetland restoration areas, as well as two additional reference wells
installed in the downstream portion of the UT3 wetland restoration area. Installation of these groundwater
monitoring stations follow Corps of Engineers Wetlands Research Program Technical Note VN-rs-4.1 (USAGE
1997).
As described in Section 2.2.1, to provide additional groundwater data during the monitoring period, four new
monitoring wells were installed at the beginning of the growing season in April 2O16. These four additional
wells provide additional wetland success data, as well as collect groundwater levels adjacent to the areas where
the additional ditching repairs will take place. The four new wells installed as shown in Figure 2.
The automated loggers are programmed to collect data to document groundwater levels in the restored wetland
areas. The success criteria for wetland hydrology are considered to have been met when the site is saturated
within 12 inches of the soil surface for a consecutive number of days equal to a minimum of 12% of the growing
season (34 consecutive days at this site). Results indicate that only monitoring wells 1 and 5 met the minimum
saturation success criteria (both adjacent to UT2). As -built monitoring wells 2, 3, 4 and supplemental
monitoring wells 6, 7, 8 did not meet success during Year 3. It should be noted that wells 5 through 8 were
installed between April 23' and April 29th, thus missing collecting groundwater data for 55 to 61 days of the
early growing season when groundwater levels are typically at their highest. The rainfall graphs should also be
closely reviewed in Appendix D. Very little rain fell at the Site during the critical periods of early spring and
late fall. The total rainfall for the year is not far from the historical average but the rain came in large quick
events, which did not allow for slow and steady infiltration and groundwater recharge. Restoration well data
and reference well data collected during Year 3 monitoring are located in Appendix D.
2.2.1 Wetland Concerns
Ditching
In the fall of 2015, the restoration site landowner cut a network of drainage ditches adjacent to the
easement boundaries of both UT2 and UT3 (See Figure 3). The landowner implemented a plan to re-
cut pre-existing ditches that joined a new deeper ditch that directly abuts the Site's conservation
easements. These new ditches were cut on the eastern and western boundary of UT2 as well as the
western boundary of UT3. The landowner cut the ditches with the intent to drain water away from his
pine plantation that abuts both easement boundaries on the west and east. Additionally, the property
and farm access road that lies to the north of the Site is also retaining water and needs to drain across
the northern road into the conservation easement to prevent hydrologic trespass.
The work described above was designed and implemented without first consulting Baker. The ditches
were first discovered during fall monitoring in fall 2O15.
To remedy the potential impacts of the new ditch network on restored wetland functions, Baker
implemented a work plan to alleviate the hydrologic trespass outside of the conservation easement and
MICHAEL BAKER ENGINEERING, INC. 4
ST. CLAIR CREEK RESTORATION PROJECT, DMS PROJECT NUMBER - 95015
JANUARY 2017. MONITORING YEAR 3 OF 7
filled the new ditches so wetland hydrology would be unimpaired. The proposed work took place in
March 2016 in three different locations (Figure 3). (1) The northern conservation easement boundary
of UT 2 along the existing farm road, (2) the western conservation easement boundary of UT2 along
the wetland restoration area, and (3) along the western conservation easement boundary of UT3 along
the wetland restoration area.
Location (1): Work in this area consisted of connecting existing shallow drainage ditches from an
adjacent property across the farm road into the conservation easement of UT2. A shallow ditch (1' deep
by 2' wide) was cut through the farm road and then filled with rip rap outside of the easement to allow
water to filter through the rock (French drain) and move across the road, but also allows the landowner
to cross easily. Once the rock -filled ditch reaches the conservation easement boundary, a shallow,
wide, flat depression (10' wide by 1' deep with a 0% slope) was excavated to tie these depressions into
the existing ground elevations within the conservation easement. The locations shown as pink lines on
Figure 3 are to scale (length) and are aligned as such to utilize the existing drainage paths as discovered
during a field visit for storm event. It was observed during Year 3 monitoring that flow now diffuses
through these depressions. These areas within the conservation easement were seeded and re -planted
with bare -root trees.
Location (2): Work in this area consisted of excavating shallow and wide depressions through the
wetland restoration polygon along UT 2 to connect and help drain the existing lateral ditches outside
the conservation easement that were plugged during construction. The depressions constructed are
approximately 10' wide and 1' deep. The depression depth of V was measured down from the existing
ground surface inside the wetland area at the conservation easement boundary with the intent to prevent
hydrologic trespass within the landowner's existing pine timber. The depression bottoms are
significantly higher than the existing lateral ditch bottoms within the timber. The depressions are
essentially a zero slope and rely on the hydraulic head from the groundwater within the timber to
promote flow. The depressions were excavated inside the conservation easement only as far as needed
to tie into the existing ground elevations. The constructed lengths of these depressions are shown to
scale in Figure 3. The required excavations are shallower as the depressions get closer to the stream
valley. In addition, the excavated ditch adjacent to the conservation easement was filled. This is shown
as a green dashed line on the attached figure. The small amount of flow that this depression receives
flows diffusely as observed during Year 3 monitoring. The disturbed areas within the conservation
easement were seeded and re -planted with bare -root trees.
Location (3): Work in this area will consisted of removing a small (-5' wide) plug that separated the
newly excavated ditch along UT3 (dashed green line in Figure 3) and existing small depressions within
the conservation easement. These depressions were likely old remnant ditches excavated many years
before the current conditions. These depressions are vegetated and shallow which serves to prevent
hydrologic trespass in the timber areas outside the conservation easement between UT 2 and UT 3.
Additionally, at the time of construction it was determined based on field observations that an additional
shallow ditch would need to be excavated to 151 feet through the wetland restoration polygon (Ditch
5) along UT 3 to connect and help drain the existing lateral ditches outside the conservation easement
that were plugged during construction. The depressions constructed are approximately 10' wide and 1'
deep. Little to no grading will be required inside the conservation easement along UT 3 except Ditch
5.
In addition, the excavated ditch adjacent to the conservation easement was filled. Construction of the
proposed activities as described above was implemented in Year 3 (March 2016).

Logging Issues and Additional Monitoring Wells
It is noted that in the spring of 2015 three wetland restoration wells (SCAW1, SCAW2 and SCAW4)
had accumulated bentonite/mud in the bottom of the well casings. A thick, gooey material was found
to be clogging the water pressure sensors located in the bottom of the pressure transducers. This
accumulation of material was suspected to be the likely the cause for the observed erroneous water
levels recorded in the well casings. To verify groundwater depths and check for logger accuracy,
manual groundwater measurements were recorded during three site visits and compared to datalogger
readings in the appropriate date/time windows. The manual measurements were then used to determine
if there were any significant differences in the recorded groundwater levels. After comparing the data,
it was found that three wetland restoration loggers had errors in depth other than what was recorded
manually. To correct this issue, all well casings, including SCAW3 were pumped to clear excess
bentonite/mud that had built up and to prevent further buildup on the pressure sensors. The on-site
reference wells were not pumped during this time. Additionally, links in the suspension chains from
which the loggers hang in the well casings were also removed so the chain would be shorter. This was
an effort to raise the loggers off the bottom of the well casings as to be above the bentonite/mud buildup.
Subsequent to these adjustments, all on-site well data loggers now are free of bentonite and the
atmospheric pressure hole is clear of any obstructions.
As stated in Section 2.2, four new (supplemental) monitoring wells were installed in April /2016. These
additional wells will provide additional wetland success data, as well as collect groundwater levels in
the areas adjacent to where the additional ditching repairs have taken take place. These four new wells
were installed as shown in the CCPV (Figure 2).
2.3 Vegetation Assessment
In order to determine if the criteria are achieved, vegetation -monitoring quadrants were installed and are
monitored across the restoration site in accordance with the CVS-NCDMS Protocol for Recording Vegetation,
Version 4.1 (2007) and the CVS-NCDMS data entry tool v 2.3.1 (2012). The vegetation monitoring plots are
a minimum of 2 percent of the planted portion of the Site with nine plots established randomly within the Site's
planted riparian buffer areas per Monitoring Levels 1. The sizes of individual quadrants are 100 square meters
for woody tree species.
Year 3 vegetation assessment information is provided in Appendix B and C.
2.3.1 Vegetation Concerns
Following Year 2 monitoring, Pinus taeda (loblolly pine) was documented in the area of UT2. The
loblolly pines were short but had the potential to pose a future threat to the survival of planted species
installed during the construction phase. To prevent this nuisance species from affecting the planted
stems, a thinning and removal effort took place in March 2016 and targeted the loblolly pine. The
methods used were hand/power tools and chemical applications.
Additionally, during the fall of Year 3 monitoring, Pinus taeda (loblolly pine) was still documented in
the area of UT2 as well as the UT3 area. The loblolly pines were noted to be widely dispersed across
both reaches of the site. This nuisance species still poses a future threat to the survival of planted
species installed during the construction phase. Additional treatment of the loblolly pines are once
again planned for treatment in during Year 4/2017. The methods to be used will be hand/power tools
and chemical applications.

'Indicates the percentage of most consecutive or cumulative number of days within the monitored growing season with a water 12 inches or less from the soil surface.
2Indicates the most consecutive number of days within the monitored growing season with a water table 12 inches or less from the soil surface.
'Indicates the cumulative number of days within the monitored growing season with a water table 12 inches or less from the soil surface.
Growing season for Beaufort County is from February 28 to December 6 and is282 days long. 12% of the growing season is33.8 days.
HIGHLIGHTED indicates wells that did not to meet the success criteria for the most consecutive number of days within the monitored growing season with a water 12
inches or less from the soil surface. Following Year 3 wetland monitoring, two of eight wells exhibited hyrdroperiods greater than 12% during the 2016 growing season.
These wells will be observed closely throughout monitoring Year 4.
**To gather additional well data in the wetland restoration area, In -Situ groundwater monitoring dataloggers SCAW5 - SCAW 8 were installed in April 2017. The installatio
of the additional dataloggers was completed during the 2016 spring wet season when groundwater levels are normally closer to the ground surface.
