Re: Response to Sandy Bridge Farm MY04 Report Comments
Dear Mr. Tsomides,
KCI has reviewed the comments prepared by the DMS for the Sandy Bridge Farm MY04 Report
and has prepared the following responses:
1. Aggradation (attributed to beaver)is noted in the text as a site issue however the visual
assessment table indicates 100% of the project performing as intended for the aggradation
metric. Both pool cross sections (XS2 and XS4) are showing the pools with significant
filling in. Please field-verify and quantify/update the visual assessment tables every year
as appropriate.
KCI Response: The Visual Assessment Table and the CCPV have been updated to reflect
the aggradation that is present on-site as a result of the beaver impoundments.
2. Please submit the features used to characterize the supplemental planting areas displayed
in the CCPV.
Please submit photo point features attributed with unique ID's.
Please submit groundwater gauge features attributed with unique ID's.
Please submit vegetation plot features attributed with unique ID's.
KCI Response: These files have been added to the digital deliverables along with a
shapefile characterizing the aggradation areas.
Please contact me if you have any questions or would like clarification concerning these
responses.
Sincerely,
Tim Morris
Project Manager

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.

DMS Project#96920 1 2020-MY04

The majority of monitoring components were installed in March 2017. Nine groundwater
monitoring gauges 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 m x 10 m
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 gauges and two additional vegetation plots. On March 30,
2018 the three additional groundwater monitoring gauges 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. On March 27,2020,a supplemental planting
was completed on the site. 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 correcting a small
area of low growth and vigor caused by heavy growth of herbaceous vegetation. The planting in
the central portion of the site, however, was done simply as a preemptive attempt to mitigate
damage done by the beavers. At this time KCI does not believe that the beavers represent a threat
to the vegetative success of the site but is continuing to monitor their impact on 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
Vegetation monitoring did not take place during the fourth monitoring year, as stipulated in the
mitigation plan. Overall the site is well vegetated despite the impact the beavers have had on the
site. Many large, healthy trees (> 10 feet tall) are present throughout the site. Vegetation
monitoring will resume in MY05.
Daily rainfall data were obtained from the NC State Climate Office for a local weather station in
Rutherfordton, NC. In 2020 the months of January, February, April, May, July, August,
September, October, and November experienced above average rainfall, while June experienced
average rainfall. The month of March experienced below average rainfall for the site. Overall,the
area experienced above average rainfall during the 2020 growing season. During the site's fourth
growing season, ten of the twelve groundwater monitoring gauges had continuous saturation
within 12 inches of the ground surface for 10% (22 days) or more of the 217 day growing season

(April 4 to November 6). Both of the two gauges that did not achieve the success criteria
malfunctioned. One gauge continuously malfunctioned for the entire year, while the other only
recorded a portion of the growing season. While these issues were thought to be fixed during the
regular downloads this summer, they persisted and these gauges have been replaced so that we
will have valid data in 2021. Even without the data from these two gauges,the fact that all of the
other gauges met the hydrology criteria, we are confident that these parts of the site also met for
2020.
The stream gauge has recorded multiple bankfull events in each year since construction,including
6 bankfull events in 2020. 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
on site. Since then KCI has been continuously monitoring for further signs of beaver activity,
trapping beavers on-site and removing dams when they are found. Dams were removed in August
2018,November 2018, June 2019, August 2019, October 2019, June 2020, and September 2020.
In August 2020 KCI contracted with USDA APHIS-WS to provide ongoing beaver management.
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. Though not normally a part of monitoring year 4,the
IRT requested that KCI conduct cross-section surveys in 2020 to monitor this situation. The
fourth-year cross-section survey showed aggradation in the pool cross-sections (XS2 and 4) as
well as aggradation on the banks of Cross-section 1. One of the beaver dams that was removed in
June 2020 was located at the head of the riffle just below XS2. Another dam is located
approximately 100 if downstream from XS4. These dams had previously been removed in 2018
and 2019. During MY02, a mid-channel bar was recorded in the survey of XS2 as a result of
backwater from the beaver dams. After the dams were removed, the sediment forming this bar
washed through and it was no longer present during the MY03 survey. Due to the continued
rebuilding of dams,the accumulated sediment did not have a chance to wash out of the channel in
2020. Over the next few years of monitoring we will continue to monitor this situation as we
continue to remove beavers and beaver dams. It is believed that the sediment that has built up
within the stream will wash out if given enough time after the removal of the beaver dams. It's
important to note that even with the rebuilding of the dams,the stream flow has stayed within the
restored channel and we have not seen any evidence of other channels forming in this system.
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 along the easement's southern boundary had been
experiencing significant erosion due to several areas of obstruction in the center of this channel
that are 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 has encroached into the
easement. In November 2019, KCI repaired and stabilize 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 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.
