RE: Cochran Branch Stream and Wetland Restoration Site: MY3 Monitoring Report
(NCDMS ID 95720)
Listed below are comments provided by DMS on January 10, 2018 regarding the Cochran
Branch Stream and Wetland Restoration Site: Year 3 Monitoring Report and RES' responses.
Cover: Please include the USACE Permit Action ID and the DWR Project Number on the report
cover page.
Done.
General: As noted in the report text; Cochran Branch is one of the projects that the IRT has
requested be reverted to the Mitigation Plan asset totals prior to the 2018 credit release.
Wetland assets have remained consistent since the approve mitigation plan so those will not be
updated. Total stream assets will be reduced to 1,783 SMUs (1,387 SMUs on Cochran Branch
& 396 SMUs on Parrish Branch) per the approved mitigation plan.
Contract 004947 stipulates a total of 1,756 SMUs so this update will not affect the current
invoicing pay schedule.
General: At the April 3, 2017 IRT Credit Release Meeting, the IRT took issue with RES not
collecting stream data in MY2. RES agreed to collect stream data in MY4 (2018) to compensate
for this IRT concern. This has been reported in the MY3 text and RES plans to collect stream
data in MY4 (2018) accordingly.
General: As a project objective is to eradicate invasive, exotic or undesirable plant species,
please be sure to closely monitor and treat invasive species along the entire conservation
easement through project closeout. At project closeout, the regulatory agencies may expect no
living exotic invasive species within the project conservation easement based on the objective.
Section 1.1 - Goals and Objectives: Objectives — Update 1,882 feet to 1,783 feet per the
approved mitigation plan.
Done.

Section 1.4.1 - Vegetation: Invasive species were noted in the report verbiage and the CCPV
mapping. Please note if any invasive treatment was conducted in MY3 (2017). In the report
verbiage, please indicate if an invasive treatment is planned for the site in MY4 (2018).
No invasive treatment was conducted in MY3. The invasives are limited to the edge of the
easement boundary and will be treated in MY4. This has been added to the report.
As reported in Table 7, please report the estimated average planted stem tree height observed
in MY3 (2017) in the report verbiage.
Done.
Table 1: Please revert Table 1 back to the totals found in the Mitigation Plan. Add a note at
bottom of table to acknowledge communications with IRT regarding the change. Suggested
table note: "* Stream credit calculations were originally calculated along the as -built thalweg.
Based on the April 3, 2017 IRT Credit Release Meeting, these stream credits have been
reverted back to the amounts in the IRT approved mitigation plan."
Done.
Table 2: Please list all invasive -exotic treatments in Table 2. The report text indicates MY2-2016
invasive treatments within the conservation easement but none are shown in the table.
Done.
Cross Sections / Cross Section Tables — A couple of methods are currently being utilized to
calculate the BHR from year to year. To compare subsequent monitoring years to the As -built
condition one can hold the bankfull depth static (denominator) while allowing the Low TOB max
depth (numerator) to vary. Another method that has been proposed and is being evaluated is to
hold the As -built cross sectional area static within each year's new cross section and allow that
to determine the max bankfull depth for each year. However; if there are large changes in the
W/D ratio either method can make for somewhat distorted BHR values depending upon the
direction and magnitude of the change in the W/D ratio. Please update the calculations to reflect
changes observed in the overlays and explain in detail as a table footnote how the calculations
were made. Be prepared to defend the method used for the 2018 credit release and justify
through context whether or not any changes observed in a cross section represent an issue.
BHR was calculated on riffles using the baseline bankfull elevation. This method was used
because the dimension of the channels has not changed enough to alter the bankfull elevation.
None of the riffle cross sections exceeded a 1.2 BHR. This has been added to the text and as a
footnote to Table 11 a.
Table 14: Please provide estimated dates for the bankfull events reported in the table. Please
also note that three bankfull events were reported on Parrish Branch.
Done.
Wetland Reference Gauge: A Macon County wetland reference gauge is noted in the report
text on the Cat Creek site but the data is not included in the appendices or the support files.
Please provide the wetland reference gauge data in the FINAL revised report and updated
support files.
The reference gauge located at the Cat Creek site failed to collect data in 2017. The gauge will
be replaced and data will be reported in 2018. This has been added to the text.

Year 3 Monitoring Report • Macon County, North Carolina • January 2018
1.0 PROJECT SUMMARY
1.1. Goals and Objectives
The overall goals address the stressors identified in the TLW and include the following:
• Improve water quality within the restored channel reaches and downstream watercourses by
reducing sediment and nutrient inputs and increasing dissolved oxygen levels
• Improve local aquatic and terrestrial ecological function through increased stream shading,
habitat complexity, and availability of organic/woody material
• Improve aquatic and benthic habitat and associated streambed form
• Improve site hydrology, wetland functions, and attenuation of flood flows
• Provide riparian area and wetland restoration with a native plant community
• Protect the site from future land impacts
The specific project objectives that are intended to target the above goals include the following:
• Implement Priority I and II restoration of 1,783 feet of stream and rehabilitation/re-
establishment of 4.35 acres of wetlands
• Implement appropriate changes in dimension, pattern and/or profile to establish
geomorphically stable conditions within the project reaches
• Modify degraded stream channels to enable proper sediment transport capacity and improved
streambed form
• Integrate in -stream structures and native bank vegetation
• Re -grade the floodplain to remove drainage ditches, spoil berms, and overburden soil
• Plant native woody and herbaceous riparian vegetation within a minimum width of 30 feet
from the edge of the restored channels and throughout the restored wetland area
• Eradicate invasive, exotic or undesirable plant species
• Install livestock exclusion fencing
• Establish a permanent conservation easement
1.2. Success Criteria
1.2.1. Morphological Parameters and Channel Stability
Restored and enhanced streams are in compliance with the standards set forth in the USACE 2003
Stream Mitigation Guidelines and the "Ecosystem Enhancement Program Monitoring Requirements
and Performance Standards for Stream and Wetland Mitigation" dated November 7, 2011. Restored
and enhanced streams should demonstrate morphologic stability to be considered successful. Stability
does not equate to an absence of change, but rather to sustainable rates of change or stable patterns of
variation. Restored streams often demonstrate some level of initial adjustment in the several months
that follow construction and some change/variation subsequent to that is also to be expected. However,
the observed change should not be unidirectional such that it represents a robust trend. If some trend
is evident, it should be very modest or indicate migration to a stable form.
Dimension - Cross-section measurements should indicate little change from the as -built
cross-sections. If changes do occur, they will be evaluated to determine whether the
adjustments are associated with increased stability or whether they indicate movement
towards an unstable condition.
Pattern and Profile - Visual inspection of the pattern and profile should indicate stability
with little deviation from as -built conditions for the restored stream. Pool depths may vary
from year to year, but the majority should maintain depths sufficient to be observed as
distinct features. The pools should maintain their depth with flatter water surface slopes,
Resource Environmental Solutions, LLC

Cochran Branch Stream and Wetland Restoration Site
Year 3 Monitoring Report • Macon County, North Carolina • January 2018
while the riffles should remain shallower and steeper. Pattern and profile measurements will
not be collected unless conditions seem to indicate that a detectable and detrimental change
appears to have occurred.
Substrate - Calculated Dso and Dsa values should indicate coarser size class distributions of
bed materials in riffles and finer size class distributions in pools. The majority of riffle
pebble counts should indicate maintenance or coarsening of substrate size class distributions.
Generally, it is anticipated that the bed material will coarsen over time.
Sediment Transport - Depositional features should be consistent with a stable stream that is
effectively managing its sediment load. Point bar and inner berm features, if present, should
develop without excessive encroachment of the channel. Isolated development of robust
(i.e. comprised of coarse material and/or vegetated actively diverting flow) mid -channel or
lateral bars will be acceptable. Likewise, development of a higher number of mid -channel
or lateral bars that are minor in terms of their permanency such that profile measurements do
not indicate systemic aggradation will be acceptable, but trends in the development of robust
mid -channel or alternating bar features will be considered a destabilizing condition and may
require intervention or have success implications.
1.2.2. Surface Water Hydrology
Monitoring of stream surface water stages should indicate recurrence of bankfull flow on average every
1 to 2 years. At a minimum, throughout the monitoring period, the surface water stage should achieve
bankfull or greater elevations at least twice. The bankfull events must occur during separate monitoring
years.
1.2.3. Groundwater Hydrology
The USACE defines minimum hydrology for jurisdictional wetlands to be saturation within 12 inches
of the surface for at least 5% of the growing season if soils and vegetation meet jurisdictional criteria.
Given that hydric soils are present throughout the restoration area but that wetland vegetation will be
newly established, it is reasonable to set the minimum hydrology threshold slightly above the
jurisdictional minimum threshold. As such, the minimum performance standard is set to provide
saturated soils within 12 inches of the surface for at least eight percent (8%) of the growing season
under average climatic conditions. In the event of non -typical years of climatic conditions, groundwater
monitoring data should demonstrate similar hydro -periods when compared to reference wetland
groundwater data. The reference wetland site will be the NCDMS Cat Creek Stream and Wetland
Restoration Site — NCDMS Project # 71— located east of Franklin in Macon County, NC. The growing
season for the site was based on the Natural Resource Conservation Service (MRCS) WETS dataset for
Macon County (http://agacis.rcc-acis.org/37113/wets). The Macon County dataset is based on a site
with elevations roughly the same as the project site. According to NRCS, the growing season for
Macon County is defined to be the period with a 50% probability that the daily minimum temperature
is higher than 287. At the project site, this period extends from April 16' to October 19' for a total
of 187 days. Based on this, wetland hydrology success will be achieved if the water table is within 12
inches of the soil surface for one or more periods of at least 15 consecutive days during the growing
season.

Year 3 Monitoring Report • Macon County, North Carolina • January 2018
1.2.4. Vegetation
Riparian vegetation monitoring shall be conducted for a minimum of seven years to ensure that success
criteria are met per USACE guidelines. Accordingly, success criteria will consist of a minimum
survival of 260 planted stems per acre by the end of the Year 5 monitoring period and a minimum of
210 planted stems per acre at the end of Year 7. If monitoring indicates either that the specified survival
rate is not being met or the development of detrimental conditions (i.e., invasive species, diseased
vegetation), appropriate corrective actions will be developed and implemented. Additionally, planted
vegetation must average 8 feet in height in each plot at year 7 (as defined in the USACE 2003). If this
performance standard is met by year 5 and stem density is trending toward success (i.e., no less than
260 five year-old stems/acre) monitoring of vegetation on the site may be terminated provided written
approval is given by the USACE in consultation with the North Carolina Interagency Review Team
(NCIRT).
1.3. Project Setting and Background
The Cochran Branch Mitigation Project (The Site) is located approximately 6 miles northwest of
Franklin, North Carolina at latitude 35012'52" N and longitude 83°29'20" W. The Site encompasses
approximately 10 acres of agricultural land and consists of two streams, Cochran Branch and Parrish
Branch, along with 4.35 acres of wetlands on the Cochran Branch floodplain. The Site lies within the
Little Tennessee River Watershed N.C. Division of Water Resources (DWR) sub -basin 04-04-01 and
local HUC 06010202040020. The project is located within the NCDMS Iotla Creek targeted local
watershed (TLW) and within the Franklin to Fontana local watershed plant (LWT). Cochran Branch
drains to Burningtown Creek approximately 0.5 miles downstream of the project. Burningtown Creek
is classified as B;Tr by NCDEQ.
Following 2016 monitoring the NCIRT requested a review of the differential between the Approved
Mitigation Plan and Baseline Monitoring Report. The table below details the discrepancies by reach.
The cause of increased baseline SMUs is survey methodology (thalweg vs. centerline) as well as
construction field adjustments. The Mitigation Plan lengths were based on centerline. Wetland credits
are unchanged from Mitigation Plan to Baseline Monitoring Report.

1.4. Project Performance
Monitoring Year 3 (MY3) data was collected from April through October 2017. Monitoring activities
included visual assessment of all reaches and the surrounding easement, collection of images at eight
permanent photo stations, and inventory of eight permanent vegetation monitoring plots. Monitoring
activities also included stream monitoring consisting of nine cross-sections, five pebble counts, and
three bank pin arrays. Stream monitoring was not performed in MY2 and will be completed in MY4 as
a replacement for the lack of data collection.
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
Resource Environmental Solutions, LLC

Cochran Branch Stream and Wetland Restoration Site
Year 3 Monitoring Report • Macon County, North Carolina • January 2018
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 the NCDMS website
(http://portal.NCDEQ.org/web/eep). All raw data supporting the tables and figures in the appendices
is available from DMS upon request.
1.4.1. Vegetation
Visual assessment of vegetation outside of the monitoring plots (Appendix B — Table 6) indicates that
the herbaceous vegetation is becoming well established throughout the project. Populations of Chinese
privet (Ligustrum sinense) and multiflora rose (Rosa multiflora) were treated in 2016 but the invasive
species are still present along the easement boundary in lower densities. Follow-up treatments will be
performed in MY4 and as needed in future monitoring years.
Monitoring of the eight permanent vegetation plots was completed during October 2017. Summary
tables and photographs associated with MY3 monitoring are located in Appendix C. MY3 monitoring
data indicates that all plots met interim success criteria of 320 planted stems per acre. Planted stem
densities among plots ranged from 324 to 647 planted stems per acre with an annual mean of 470
planted stems per acre across all plots. A total of 12 species were documented within the plots. When
volunteer stems are included, the mean annual total stems per acre rose to 516 and ranged between 324
and 769 stems per acre. The estimated average tree height observed was 89 cm (2.9 ft). Missing stems
from the failing Vegetation Plot 6 were located in MY3 and the plot is now exceeding success criteria.
1.4.2. Stream Geomorphology
Visual assessment of the stream channel was performed to document signs of instability, such as
eroding banks, structural instability, or excessive sedimentation. No indication of instability was
observed during visual assessment and all structures are functioning as designed (Appendix A Figure
2 and Appendix B Table 5).
Geomorphic data for MY3 was collected during October 2017. Summary tables and cross-section plots
related to stream morphology are located in Appendix D. Cross-sectional overlays showed minimal
dimensional change between MY2 and MY3 data collection efforts (Appendix B; Table 11 a). Starting
in MY3, BHR was calculated on riffles using the baseline bankfull elevation. This method was used
because the dimension of the channels has not changed enough to alter the bankfull elevation. None of
the riffle cross sections exceeded a 1.2 BHR.
Substrate monitoring was performed during MY3. Pebble count D50 was coarse gravel for Reach 1,
and very coarse gravel for Reach 2. The channel substrate will be monitored in future years for shifts
in particle size distributions.
The bank pin arrays indicate that no erosion is taking place in the meanders during MY3 (Appendix
D; Table 12).
1.4.3. Groundwater and Stream Hydrology
During MY3, seven of the eight groundwater monitoring wells met the 8 percent hydroperiod success
criteria (Appendix E; Table 16). Groundwater Monitoring Well 1, located outside of the wetland re-
establishment area, was the only well not to meet success criteria. Hydroperiods among the monitoring
wells ranged from 1 to 92 percent of the growing season. Total number of consecutive days within 12
inches of the soil surface ranged from 2 to 171. The reference gauge located at the Cat Creek Site failed
to collect any data in 2017. It will be replaced and reference data will be included in the next monitoring
report.

Cochran Branch Stream and Wetland Restoration Site
Year 3 Monitoring Report • Macon County, North Carolina • January 2018
One bankfull event occurred on Cochran Branch (mainstem) and three events occurred on Parrish
Branch during MY3. The highest events measured 0.92 and 0.79 respectively (Appendix E; Table 14).
This is the fourth bankfull event recorded on Cochran Branch and the first three recorded on Parrish
Branch since project completion.
2.0 METHODS
This report presents the results of the Monitoring Year 3 (MY3) visual, hydrologic, morphological, and
vegetation data. Permanent photo station photos were collected during the initial visual assessment;
during leaf -off conditions. Additional photos of vegetation or stream problem areas were taken as
needed.
Geomorphic measurements were taken during low flow conditions using a Topcon GTS -312 Total
Station. Three-dimensional coordinates associated with cross-section data was collected in the field and
geo-referenced (NAD83 State Plane feet FIPS 3200). Morphological data was collected at 9 cross-
sections. Survey data was imported into CAD, ArcGIS®, and Microsoft Excel® for data processing and
analysis. Channel substrate was characterized using a Wolman Pebble Count as outlined in Harrelson
et al. (1994) and processed using Microsoft Excel.
Vegetation success is being monitored at eight permanent monitoring plots. Vegetation monitoring
follows the CVS-EEP Level 2 Protocol for Recording Vegetation, version 4.2 (Lee et al. 2008) and
includes analysis of species composition and density of planted species. Data is processed using the
CVS data entry tool. In the field, the four corners of each plot were permanently marked with rebar and
photos of each plot taken from the origin each monitoring year.
Precipitation data was collected using an Onset HOBO Data Logging Rain Gauge. Groundwater for
hydrologic success of restored wetlands was monitored using eight HOBO U20 Water Level Loggers.
An additional logger was installed on site, above ground, for use as a barometric reference. Data loggers
collected depth to groundwater daily and all data were processed using HOBOware and analyzed using
Microsoft Excel. Bankfull events were documented with two crest gauges, one each being located on
Cochran Branch and Parrish Branch. During quarterly visits to the site, the height of the corkline was
recorded.

The subject project site is an environmental restoration site of the
NCDWQ Division of Mitigation Services (DMS) and is J
encompassed by a recorded conservation easement, but is
bordered by land under private ownership. Accessing the site may
require traversing areas near or along the easement boundary and
therefore access by the general public is not permitted. Access by
authorized personnel of state and federal agencies or their
designees/contractors involved in the development, oversight and
stewardship of the restoration site is permitted within the terms and /
timeframes of their defined roles. Any intended site visitation or
activity by any person outside of these previously sanctioned roles
and activities requires prior coordination with DMS.
