Re: Response to Sandy Bridge Farm MY05 Report Comments
Dear Mr. Tsomides,
KCI has reviewed the comments prepared by the DMS for the Sandy Bridge Farm MY05 Report
and has prepared the following responses:
• Please update the Monitoring Phase Performance Bond as necessary.
KCI Response: The Performance Bond will be updated.
• Please include the meeting notes and figure from the June 28, 2021 meeting with KCI,
DMS and IRT.
KCI Response: These have been included in Appendix F Other Data
• Please add a call out for the ponded BMP area on the CCPV, see Kim's 6/30/2021 email.
KCI Response: This change has been made.
• Can the aerial photo in the Site Asset Map be updated? This 2015 photo shows the old
channel alignment and pre -construction conditions.
KCI Response: The aerial photo in the Site Asset Map has been updated to 2019 imagery.
• In Table 1, please take the riparian wetland assets (6.65 wmu) out one additional
significant digit (currently tracked as 6.653 wmu).
KCI Response: This change has been made.
• If beaver or dam removal has occurred since observed in August 2021, please update the
project activities table.
KCI Response: The last beaver dam removal was in August 2021. Beaver dams are
currently present on the site and will be removed once the beavers have been trapped and
removed from the site.
• It is understood that beaver have caused most of the vegetation damage and the site
vegetation is doing well overall, but is KCI planning any additional planting and/or MY6
vegetation monitoring based on the MY5 plot attainment data? Please address the plot
non -attainments in VPs 1, 3, 5, and 6 in more detail.

KCI Response: No additional planting is planned for the Sandy Bridge site. Overall the
site is well vegetated with many large and healthy trees present throughout the site.
While VP I and 3 are below the Year S success criteria of 260 stems/acre, they are above
the Year 7 success criteria of 210 stems/acre and so do not present a long term problem
for the site's success. Additionally, all 4 of the low performing veg plots have at least 283
stems/acre when including volunteers. All of the volunteer species in these plots, except
for one American elm, are species that were included in the planting plan. So although
the beavers have significantly damaged the vegetation on site it is still performing as
expected. It is believed that over the long term, the large, high quality seed source of
woody vegetation that is present on the site will make up for any of the small areas of the
site that are below the expected standards, as demonstrated by the presence of high
quality volunteers that can be found in nearly all of the veg plots.
Is KCI considering the field discussion from the 2021 site visit that if the rehabilitation
wetland near VP 7 and VP8 turns to more of a scrub -shrub or emergent wetland because
of the high hydro period, that those boundaries be defined in the monitoring reports?
KCI Response: KCI will continue to monitor this area closely but currently the
supplemental planting that occurred in March 2020 appears to be effectively addressing
the lack of woody vegetation in this area. The original bare root stems that were planted
in this area appear to have been too small to outcompete the tear -thumb and other
herbaceous species in this area but the larger, one gallon trees that were planted in 2020
are doing well so far.
DIGITAL SUPPORT FILE COMMENTS
Please submit the features characterizing the visual assessment as shape files or in a
geodatabase.
KCI Response: Shapefzles have been submitted for the visual assessment features.
The annual means in the submitted veg data spreadsheet are not consistent with those
included in the report. Please review and ensure that the submitted data supports the
reported values.
KCI Response: This correction has been made and the report reflects the submitted data.
Please contact me if you have any questions or would like clarification concerning these
responses.
Sincerely,
�� 7/
Tim Morris

PROJECT SUMMARY
The Sandy Bridge Farm Restoration Site (SBFRS) was completed in March 2017 and restored a
total of 6.85 acres of riparian wetland (1.29 acres of wetland rehabilitation and 5.56 acres of
wetland reestablishment) and 1,626 linear feet of stream. The SBFRS is a riparian system located
in the Broad River Basin (03050105 8-digit cataloging unit) in Rutherford County, North
Carolina that had been substantially modified to maximize the use of the area for grazing. The
completed project will restore impacted agricultural lands to a functioning stream and wetland
ecosystem with enhanced water quality, restored hydrology, and improved fish and wildlife
habitat.
The SBFRS is protected by a 9.5 acre permanent conservation easement, held by the State of
North Carolina. The site is located off of Rock Road, approximately 3 miles north of
Rutherfordton, North Carolina. The project site is bounded by interspersed pastureland and
forested land to the east, agricultural land and Rock Road to the north-northwest, and Catheys
Creek to the southwest.
The North Carolina Ecosystem Enhancement Program's (NCEEP) publication in 2009 identified
HUC 03050105070020 (Catheys Creek) as a Targeted Local Watershed (TLW). The goals and
priorities for SBRFS are based on the information presented in the Broad River Basin Restoration
Priorities: to restore wetland and stream functions, to maintain and enhance water quality, to
restore hydrology, and to improve fish and wildlife habitat (NCEEP 2009). The project goals,
which reflect those from the approved Mitigation Plan, are in line with the following basin
Priorities:
- Reduce sources of sediment and nutrients by restoring riparian buffer vegetation,
excluding livestock, and restoring natural geomorphology.
- Prioritize project implementation in the Catheys Creek local watershed planning area.
The goals for the project are to:
- Restore a channelized stream to a meandering C-type channel with a floodplain.
- Buffer and reduce sediment impacts to the project stream.
- Restore a Piedmont Alluvial Forest Community.
- Restore a wetland hydroperiod to drained and livestock -impacted land.
The project goals will be addressed through the following objectives:
- Relocate a channelized stream to its historic landscape position.
- Install an appropriately -sized channel cross-section.
- Install bedform diversity with pools, riffles, and habitat structures.
- Demarcate the project easement boundaries and fence out livestock.
- Plant the site with native trees and shrubs and an herbaceous seed mix that supports the
development of a Piedmont Alluvial Forest.
- Fill field ditches and redevelop wetland microtopography to slow the flow of surface and
subsurface drainage.
To restore the site, select ditches across the site were modified or filled and incoming surface
inputs and seeps were integrated to create a stream/wetland complex. Additionally, Tributary 1 to
Catheys Creek was improved with Priority 1 stream restoration to re -meander the stream and
elevate the groundwater table. The entire site was planted as a Piedmont Alluvial Forest
community (Schafale 2012). The site was constructed as designed with no modification from the
design plan.
Sandy Bridge Farm Restoration Site KCIAssociates ofNC, PA
DMS Project # 96920 1 2021-MY05

The majority of monitoring components were installed in March 2017. Nine groundwater
monitoring wells were installed to evaluate the attainment of jurisdictional wetland hydrology. A
stream gauge was installed on Tributary 1 to Catheys Creek to record the occurrence of bankfull
events. To determine the success of the planted mitigation areas, eight 10 in x 10 in permanent
vegetation monitoring plots were established. The location of the planted stems relative to the
origin within these plots, as well as the species, was recorded and planted stems were grouped
into size categories (0-10 cm, 10-50 cm, 50-100 cm, >137 cm). Any volunteers found within the
plots were also grouped into size categories by species, but separate from the planted stems. Six
permanent photo reference points were established and will be taken annually. Four permanent
cross -sections (two sets of coupled riffles and pools) were also established and a detailed
longitudinal profile of the stream was taken. Wolman pebble counts were performed at both of
the riffle cross -sections. The cross-section measurements will be repeated in future monitoring
years, but the longitudinal profile will only be repeated if there are concerns about bed elevation
adjustments. Reports will be submitted to DMS by the end of each monitoring year. During a site
visit with the IRT on December 6, 2017, it was requested that KCI install three additional
groundwater monitoring wells and two additional vegetation plots. On March 30, 2018 the three
additional groundwater monitoring wells were installed along the area of the filled, pre -
construction stream channel. On September 10, 2018, the two additional vegetation plots were
installed near the southern end of the site.
Vegetative success criteria for the site is 320 woody stems/acre after three years, 260 woody
stems/acre after five years, and 210 woody stems/acre after seven years. The baseline monitoring
counted an average of 647 woody stems/acre. To meet the hydrologic success criteria, the upper
12 inches of the soil profile must have continuously saturated or inundated conditions for at least
10% of the growing season during normal weather conditions. The soil survey for Rutherford
County estimates the growing season begins April 4 and ends November 6 (217 days), meaning
the water table must be within 12 inches of the surface for at least 22 consecutive days during the
growing season. A minimum of two bankfull events must also be recorded during the monitoring
period. Bank height ratios should not exceed 1.2 and the entrenchment ratios should be 2.2 or
greater. Visual assessments will also be used to identify problem areas.
MONITORING RESULTS
The site was planted in March 2017 with tree tube protection installed around many of the planted
stems. The fifth -year monitoring was conducted July 15, 2021. The site averaged 401 planted
stems/acre across all 10 plots. Six of the 10 plots had greater than 260 planted stems/acre, with
Plots 1, 3, 5, and 6 not achieving the success criteria. Including volunteers, the site averaged 567
total stems/acre. The vegetation on the site has been impacted by beavers. Although there is still a
good quantity of woody stems, many of the previously large and healthy stems have been chewed
down to a smaller size or killed by beaver activity. Even with the beaver impacts, in general, the
site is well vegetated, with widespread herbaceous coverage and many healthy planted stems.
Two of the non -attaining plots (Plots 1 and 3) are above the Year 7 success criteria, and all four
are above the Year 5 success criteria when volunteers are included (all of which in these plots are
species from the approved planting plan except for one American Elm in VP5). A supplemental
planting of the site occurred in March 2020. 524 one -gallon size trees were planted in the wetland
rehabilitation area and 1,875 bare root trees were planted in the central portion of the site and
around the stream. The planting in the wetland rehabilitation area was done as a means of
addressing a small area of low growth and vigor caused by dense herbaceous vegetation. The
planting in the central portion of the site was done to mitigate damage done by the beavers.
Daily rainfall data were obtained from the NC State Climate Office for a local weather station in
Rutherfordton, NC. In 2021 the month of March experienced above average rainfall, while the
Sandy Bridge Farm Restoration Site KCIAssociates ofNC, PA
DMS Project # 96920 2 2021-MY05

month of October experienced average rainfall. The months of January, February, April, May,
June, July, August, September, and November experienced below average rainfall for the site.
Overall, the area experienced well below average rainfall during the 2021 growing season.
During the site's fifth growing season, 11 of the 12 groundwater monitoring wells had continuous
saturation within 12 inches of the ground surface for 10% (22 days) or more of the 217 day
growing season (Apri14 to November 6).
The stream gauge has recorded multiple bankfull events in each year since construction, including
7 bankfull events in 2021. This large number of bankfull events is the desired outcome for this
project. A component of the stream design was to provide regular recharging of the riparian
wetlands from overbank stream flows. In June 2018, several large beaver dams were discovered
towards the lower half of the stream. These dams were removed in early August 2018. KCI has
been continuously monitoring for further signs of beaver activity, trapping beavers on -site and
removing dams when they are found. In August 2020 KCI contracted with USDA APHIS-WS to
provide ongoing beaver management. Additional dams were removed in November 2018, June
2019, August 2019, and October 2019, June 2020, September 2020, and December 2020. New
dams were not built on the site until August 2021. These dams will be removed once the beavers
on -site have been trapped and removed from the site. See Appendix B and Appendix D for more
information.
Due to the presence of beavers on -site, there has been more aggradation in the stream channel
than has been anticipated. KCI has been removing the beavers routinely, but when the dams are
built, sediment has deposited in the channel. The fifth -year cross-section survey showed bed
aggradation in all four cross -sections as well as aggradation on the banks of Cross -sections 1 and
2. When the beaver dams are removed for an extended period of time, there is evidence of the
accumulated sediment washing out of the stream. An example of this can be seen when
comparing the MY02 and MY03 surveys of XS2. During MY02, a mid -channel bar had formed
within this cross-section but after the removal of the beaver dams and a period of several months
without them being rebuilt, this bar was completely absent from the MY03 survey. Comparing
the W04 and MY05 surveys of XS4 also shows this pattern. Starting in MY03, a large beaver
dam was located at the head of the riffle just downstream of XS4. This dam was removed
multiple times during 2019 and 2020. After being removed in September 2020, this dam was not
rebuilt, but a new dam was constructed upstream of XS4. Comparing the W04 survey to the
MY05 survey shows that the thalweg elevation in this cross-section has dropped approximately
half a foot. KCI believes that if given enough time without backwater conditions, this trend will
hold true for the entire site. It is also important to note that even with the rebuilding of the dams,
the stream flow has stayed within the restored channel and no evidence of other channels forming
in this system has been noted.
The monitored cross-section data have been calculated by adjusting the bankfull elevation to
maintain the baseline bankfull area for each cross-section. A total cross -sectional metric has been
added to the cross-section data to indicate the cross -sectional area below the baseline bankfull
elevation. In instances where there has been some lateral aggradation and narrowing the data
show the cross-section having a significantly higher bankfull width and higher width/depth ratio
as compared to previous years. The comparison of cross-section plots between monitoring events
illustrates that this change does not indicate a problematic change in cross-section condition.
Future monitoring will show how the channel has adjusted to the varying backwater conditions
and how the stream has processed the sediment from these events.
The right bank of the stream that flows adjacent to the project's southern boundary had been
experiencing significant erosion due to several areas of obstruction in the center of this channel
Sandy Bridge Farm Restoration Site KCIAssociates ofNC, PA
DMS Project # 96920 3 2021-MY05

that were diverting water into the banks. Although this stream is not part of the project, and is
located outside of the easement bounds, the erosion on the right bank had encroached into the
easement. In November 2019, KCI repaired and stabilized this area. This work involved
removing the mid -channel obstructions and sloping back the eroding bank. 150 live stakes were
planted along this bank in March 2020. During this work, several farm gates that had become
buried in the project stream bank were removed and a small swale was dug to direct water into
the site from fields adjacent to the eastern boundary of the site. This swale was designed to drain
ponded conditions in these fields and dissipate the water throughout the wetlands on -site. See
Appendix B for more information.

Meeting
- The field visit was conducted on June 22, 2021 starting at 1lam. The conditions were
overcast at the time of the site visit. The project stream was flowing at the time of the site
visit. The site is currently in Monitoring Year 5.
- The field visit encompassed the majority of the site starting at the crossing at the upstream
end of the project and working south along the stream. The site walk targeted potential
problem areas around Veg Plots 1, 7 and 8 as well as the diversion swale, stream and BMP
area. Beaver dams were also visited.
- KCI had recently completed fence repairs associated with an overbank event where debris
had pushed over small sections of fence. These fences were repaired and reinforced in
anticipation of future overbank events which occur on average about 8 times per year. The
fence repairs were discussed during the meeting.
- Recent beaver activity was apparent on site. This was causing backwater in the stream as

well as the riparian areas. Beavers were not present on June 3rd during a monitoring visit but
were noted on the site on June 13'h when KCI was on site to do some fence repairs. USDA
Aphis was contacted and traps were set on 6/21. One beaver had been trapped on 6/22 and
traps remained in place until a second beaver was trapped and removed. When trapping is
completed the dams would be breached and normal water elevations would be restored.
- Beaver activity has been a problem on this site since Year 1 monitoring. Management of
beavers has been continuous and expensive throughout the monitoring period.
- This site could be a difficult site for the Stewardship program because there is no funding for
wildlife management and the landowner has been vocal that he is not happy about the impact
to his pastures created by the ongoing beaver activity.
- KCI will continue removing beavers through Year 7 monitoring.
- There were some areas that appeared to have low stem counts or possibly low vigor in areas
near VP1, VP2 and Gauge 2 as well as the rehabilitation wetland near VP7 and VP8. These
areas are very wet with dense herbaceous cover. The duration of inundation is likely the
cause of poor stem survival and/or vigor. These low -density areas were replanted in March
of 2020 however vegetation monitoring was not conducted in 2020 to determine the success
of the newly planted stems. Vegetation monitoring will continue in 2021 (Year 5).
- IRT suggested that if the rehabilitation wetland near VP 7 and VP8 turns to more of a scrub -
shrub or emergent wetland because of the high hydroperiod that those boundaries be defined
in the monitoring reports.
- The IRT indicated that if the site were implemented today, it could be a candidate for a
maximum hydroperiod as a performance standard; however, based on the IRT approved
mitigation plan, the site is not subject to a maximum hydroperiod success criteria.
- At the end of the meeting, the NC IRT released project credits as proposed by NC DMS
