Executive Summary
The Cochran Stream and Wetland Restoration Site (Site) is located in the Little Tennessee River
Watershed (NSCDWQ sub-basin 04-04-01 and HUC 06010202040020) approximately 6 miles northwest
of Franklin, North Carolina, in Macon County at latitude 35°12’52” N and longitude 83°29’20” W. The
site encompasses approximately 10 acres of agricultural land and consisted of two unstable streams,
Cochran Branch and Parrish Branch, along with degraded former wetlands on the Cochran Branch
floodplain.
Through the North Carolina Division of Mitigation Services full-delivery process, Environmental Banc &
Exchange, LLC, an entity of Resource Environmental Solutions, LLC, generated a total of 1,820 stream
mitigation units through Priority I and II Restoration and 4.30 wetland mitigation units through
Restoration and Rehabilitation. The goal of the project was to address the stressors identified in the
Targeted Local Watershed Plan such as improving water quality, wetland function, aquatic and terrestrial
habitat, and flood flow attenuation. The goals were addressed by restoring stable channel morphology
and sediment transport capacity, improving stream bed form and habitat, re-grading the floodplain to
remove drainage ditches, spoil berms, and overburdened soils, improving stream bank stabilization, and
providing riparian buffer restoration by re-establishing a native plant community within the easement.
Historic land use at the Site has consisted primarily of agriculture and livestock grazing. Additional land
use practices, including the excavation of drainage ditches, maintenance and removal of riparian
vegetation, and the relocating, dredging, and straightening of on-site streams have contributed to unstable
channel characteristics, degraded water quality, and degradation of prior wetlands.
The project site was delineated into two components totaling 1,882 linear feet. The Site was then
delineated into three separate reaches, Cochran Branch 1a (379 feet), Cochran Branch 1b (1,101 feet), and
Parrish Branch (402 feet). A Duke Energy Right-of-Way at the upstream end of Cochran Branch 1a
accounts for the difference between the mitigation units and total footage. Cochran Branch 1a and 1b
received Priority I Restoration while Parrish Branch received Priority II Restoration. The installation of
brush, rock, and wood structures were utilized throughout the restored reaches to provide bed and bank
stability as well as aquatic habitat. The Cochran Branch stream profile was raised to reconnect it with the
floodplain while Parrish Branch, due to topographic constraints, was repositioned to connect the channel
to the low point in the valley and the new floodplain of Cochran Branch.
Three separate wetland areas were identified within the project site. The project wetland components
include approximately 4.24 acres of wetland restoration and 0.11 acres of wetland enhancement, totaling
4.35 acres of wetlands. 3.42 acres of the total restoration acres are considered re-establishment, while the
remaining 0.82 acres are rehabilitation. Re-establishment of the wetlands on the Cochran Branch
floodplain involved the removal of overburden material to expose the underlying buried A-horizon and
hydric soils. Wetland hydrology was restored by raising the bed elevation of Cochran Branch and filling
the floodplain drainage ditches. Additional grading activities included harvesting usable topsoil material
for re-use on the re-graded floodplain, removal of spoil berms, and grading the micro-topography to
provide for additional retention of surface water and increased habitat diversity. Rehabilitation of
existing wetland on the Cochran Branch floodplain involved elimination of drainage features that are
impacting wetland hydrology and improving micro-topography to improve surface water retention.
Aggressive re-grading was limited to areas where there was more than 4 inches of overburden on a well-
defined buried A-horizon. Where re-grading was determined feasible, the topsoil and vegetation was
removed first and stockpiled for redistribution on the new floodplain surface. Re-establishment of
wetlands adjacent to Parrish Branch were re-graded to the outfall of the middle ditch to form a subdued
alluvial fan feature, typical of wetland features found on small mountain streams. The graded fan feature
ii
will be saturated with flow from the persistent seep emanating from this ditch. All Re-establishment,
Rehabilitation, and Enhancement areas were ripped to remove effects of past compaction and planted
with native wetland vegetation.
A baseline stream and topographic survey was performed between 6/12 and 6/25/2015 to document
baseline conditions at the Site. The stream pattern, profile, and dimension very closely reflected those
values outlined in the design.
A vegetation survey at the Site was conducted on May 29, 2015. Results from the initial survey indicate
that the planted stem density ranged between 647 and 850 with the mean density of 789 though all plots
in MY0. A total of nine species were documented across all plots with species diversity in the plots
ranging from three and six.
Annual monitoring will begin during in 2015 and will include stream, wetland, and vegetation monitoring
components as established in this document. Annual monitoring will occur for seven years.

Monitoring Year 0 of 7
1.0 PROJECT GOALS, BACKGROUND, AND ATTRIBUTE
1.1. Location and Setting
The Cochran Branch Mitigation Site (the Site) is located approximately 6 miles northwest of Franklin,
North Carolina at latitude 35°12’52” N and longitude 83°29’20” W. The Site encompasses
approximately 10 acres of agricultural land and consists of two unstable streams, Cochran Branch and
Parrish Branch, along with degraded former wetlands on the Cochran Branch floodplain. The Site lies
within the Little Tennessee River Watershed NC Division of Water Quality (DWQ) sub-basin 04-04-01
and local HUC 06010202040020 and is within an NCDMS targeted local watershed. Cochran Branch
drains to Burningtown Creek approximately 0.5 miles downstream of the project. Burningtown Creek is
classified as B;Tr by DWQ (2012). The site is located within the Franklin to Fontana NC-DMS Local
Watershed Plan (LWP).
The Cochran Branch Mitigation Site lies within the Southern Crystalline Ridges and Mountains Level IV
ecoregion of the Blue Ridge Level III ecoregion (USGS 2002). This ecoregion occurs primarily on
Precambrian-age igneous and high-grade metamorphic rocks, which are mostly gneiss and schist, covered
by well-drained, acidic, loamy soils. The site is located within a Type II colluvial valley (Rosgen) that
presents a structurally influenced morphology with valley cross slopes averaging 25% and longitudinal
slopes averaging 4%. The valley bottom adjacent to Cochran Branch transitions from a confined colluvial
form at the upstream end to a locally broader alluvial form that is present throughout the majority of the
site. Historic land use at the Site has consisted primarily of agriculture and livestock grazing. Additional
land use practices, including the maintenance and removal of riparian vegetation and the relocating,
dredging, and straightening of on-site streams have contributed to unstable channel characteristics and
degraded water quality.
1.2. Project 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 use impacts
The specific project objectives that are intended to target the above goals include the following:
Implement Priority I and II restoration of 1,882 feet of stream and rehabilitation/re-
establishment of 4.35 acres of wetlands
Implement appropriate changes in the 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

Establish a permanent conservation easement
1.3. Project Structure, Restoration Type and Approach
1.3.1. Project Structure
Construction of the Cochran Branch Stream and Wetland Restoration Project produced a total of 1,820
stream mitigation units and 4.30 acres of wetland mitigation units, as outline in Table 1 and depicted in
Figure 2. The project site was delineated into three components totaling 1,882 feet; Cochran Branch 1a
(379 feet), Cochran Branch 1b (1,101 feet), and Parrish Branch (402 feet). Sixty-two feet of Cochran
Branch 1a is located underneath a Duke Energy Transmission Line Right-of-Way and is not considered
creditable footage. This accounts for the difference between restored footage and stream mitigation units.
1.3.2. Restoration Type and Approach
Cochran Branch
Cochran Branch is divided into two sub-reaches; Reach 1A is the steeper upstream reach and Reach 1B is
downstream from the steeper reach and flows through the majority of the site. Reach 1A was constructed
as a Priority I restoration of a type B4 stream with moderate sinuosity and an average slope of 3.5%.
Reach 1B was constructed as a Priority I restoration of a type C4 stream with moderate sinuosity and an
average slope of 0.85%. Due to the extent of degradation, the reach was completely reconstructed. The
stream profile has been raised to reconnect it with the floodplain, which is integral to the success and
function of the proposed wetland restoration. Reconstruction of the channel provided for the
configuration of proper cross sectional geometry that reduces stress on the banks and eliminates bank
scour. Additionally, reconstruction provided the opportunity to harvest the gravel bed material in the
existing channel and utilize it to construct proper, functional riffles. Riffles constructed from native
gravel material along with in-stream structures provide immediate habitat features and a dramatic
functional lift.
Parrish Branch
Parrish Branch was constructed for restoration of a type B4 stream with moderate sinuosity and an
average channel slope of 3.3%. Full restoration addressed the degraded conditions of severe channel
incision, unstable banks and improper channel dimensions which are negatively affecting the stream
functions. A Priority II approach was required for the majority of the reach due to topographic
constraints. The downstream end of Parrish Branch was repositioned to connect the channel to the low
point in the valley and the new floodplain of Cochran Branch which was constructed as Priority I
restoration.
Wetland Rehabilitation and Re-establishment
Wetland re-establishment was integrated throughout the entire area of the Cochran floodplain that
contains hydric soils and that is not presently considered jurisdictional wetlands. Wetland rehabilitation
was completed for the extant wetlands located within the Cochran floodplain. Using the NCWAM
designations, the rehabilitation converted the existing Non-tidal Freshwater Marsh to a Bottomland
Hardwood Forrest. The re-establishment and rehabilitation of the Cochran floodplain as a Bottomland
Cochran Stream and Wetland Restoration Project 3 Equinox
NCDMS Project No. 95720 Baseline Monitoring Document
Monitoring Year 0 of 7
Hardwood Forrest corresponds with the Montane Alluvial Forrest community (NCWFAT 2010). Two
additional wetland features were also addressed that are not directly connected to the Cochran floodplain.
Wetland enhancement was completed for the existing pocket wetland located on the terrace adjacent to
the floodplain. Additionally, the restoration of Parrish Branch and adjacent field indicators of buried
hydric soils provided the opportunity to re-establish wetlands at the outfall of the middle ditch.
1.4. Project History, Contacts and Attribute Data
The project was first identified as a full-delivery mitigation project for the North Carolina Department of
Mitigation Services by Environmental Banc and Exchange, LLC, an entity of Resource Environmental
Solutions, LLC (RES). Project planning began in 2012 with the final mitigation plan completed in
September 2014 and the final design and construction plans completed in October 2014. Construction
and planting of the site was completed in May 2015. Project activities, reporting dates, project contacts,
and background information are outlined in Tables 2-4 (Appendix A).
2.0 SUCCESS CRITERIA
2.1. Morphological Parameters and Channel Stability
Restored and enhanced streams shall be 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.
2.1.1. 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.
2.1.2. 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, 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.
2.1.3. Substrate
Calculated D50 and D84 values should indicate coarser size class distribution of bed materials in riffles and
finer size class distribution in pools. The majority of riffle pebble counts should indicate maintenance or
coarsening of substrate distributions. Generally, it is anticipated that the bed material will coarsen over
time.

NCDMS Project No. 95720 Baseline Monitoring Document
Monitoring Year 0 of 7
2.1.4. 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.
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.
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
the 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 the reference wetland groundwater data. The
reference wetland site will be the NCDMS Cat Creek Stream and Wetland Restoration Site located east of
Franklin in Macon County, NC. The growing season for the site was based on the Natural Resource
Conservation Service (NRCS) WETS dataset for Macon County. The Macon County data set 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 28°F. At the project site, this period extends from April 16th to October 19th for a total of 185
days. Based on this, wetland hydrology success will be achieved if the water table is within 12 inches of
the soil surface for 15 consecutive days or more during the growing season.
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 SMGs). 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).
Cochran Stream and Wetland Restoration Project 5 Equinox
NCDMS Project No. 95720 Baseline Monitoring Document
Monitoring Year 0 of 7
3.0 MONITORING PLAN
3.1. Stream Channel Stability and Geomorphology
A total of 9 cross-sections, including 5 riffles and 4 pools, were installed upon completion of construction
and will be monitored during MY 1, 3, 5, and 7. The total number of cross-sections include six on
Cochran Branch and three on Parrish Branch. Data collected from annual monitoring will be compared
with the as-built conditions to document the current state of the channel and any trends in the stream
profile occurring throughout the monitoring period.
3.2. Stream Hydrology
A total of two crest gauges were installed on site. Crest gauges will be monitored quarterly to document
highest stage for the monitoring interval and verify occurrences of bankfull events. In addition,
observations of wrack and depositional features in the floodplain will be documented with photos.
3.3. Groundwater Hydrology
A total of eight groundwater monitoring gauges have been installed upon completion of construction and
will be monitored quarterly. Data collected from the quarterly monitoring will be compared to the
success criteria stated in Section 2.3 to determine if groundwater hydrology was met by each groundwater
monitoring gauge each monitoring year.
3.4. Vegetation
Eight vegetation monitoring plots, approximately 0.025 acres individually, were established based on
guidance given in the CVS-EEP Protocol for Recording Vegetation Version 4.2 (Lee et al. 2008). Data
was collected using the Level I protocol during initial baseline monitoring to document baseline
conditions immediately after construction and planting. Subsequent annual vegetation will use the Level
II protocol. Annual monitoring will determine planted vegetative success and the overall trajectory of
woody plant restoration and regeneration at the site. Vegetation monitoring plot corners were marked
with t-posts and PVC conduit.
3.5. Permanent Photo Stations
Permanent photo stations were established at each cross-section to digitally document annual conditions
of the left and right banks. Each vegetation monitoring plot includes a photo station taken diagonally
from the origin towards the opposite plot corner. Additionally, 16 permanent photo stations were
established throughout the project area to provide representative digital documentation of stream features
and vegetation conditions. Permanent photo stations were marked with labeled wooden stakes and red
flagging tape.
3.6. Maintenance and Contingency
RES and Equinox will monitor the site on a regular basis and shall conduct a physical inspection of the
site a minimum of once per year throughout the post-construction monitoring period until performance
standards are met. These site inspections may identify site components and features that require routine
maintenance. Routine maintenance should be expected most often in the first two years following site
construction and may include the following:
Stream- Routine channel maintenance and repair activities may include chinking of in-stream
structures to prevent piping, securing of loose coir matting, and supplemental installations of live
stakes and other target vegetation along the channel. Areas where storm water and floodplain
flows intercept the channel may also require maintenance to prevent bank failures and head-

cutting. Management of beaver activity will include removal of nuisance beavers and beaver
dams that affect the stream.
Wetland- Routine wetland maintenance and repair activities may include securing of loose coir
matting and supplemental installations of live stakes and other target vegetation within the
wetland. Areas where storm water and floodplain flows intercept the wetland may also require
maintenance to prevent scour.
Vegetation- Vegetation shall be maintained to ensure the health and vigor of the targeted plant
community. Routine vegetation maintenance and repair activities may include supplemental
planting, pruning, mulching, and fertilizing. Exotic invasive plant species shall be controlled by
mechanical and/or chemical methods. Any vegetation control requiring herbicide application will
be performed in accordance with NC Department of Agriculture (NCDA) rules and regulations.
Site Boundary- Site boundaries shall be identified in the field to ensure clear distinction between
the mitigation site and adjacent properties. Boundaries may be identified by fence, marker,
bollard, post, tree-blazing, or other means as allowed by site conditions and/or conservation
easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced
on an as needed basis. Boundary markings will comply with requirements of the RFP Addendum
titled “Full Delivery Requirement for Completion of Survey for Conservations Easements” dated
7/21/11.
Utility Right of Way- Utility rights-of-way within the site may be maintained only as allowed by
Conservation Easement or existing easement, deed restrictions, rights of way, or corridor
agreements.
4.0 BASELINE CONDITIONS
A baseline survey was performed between June 15 and June 25, 2015 to document baseline conditions at
the site. A vegetation survey was conducted on May 29, 2015 to document planted vegetation after
construction for future comparison.
Reach summary tables, cross-section summary tables, and cross-section plots related to stream
morphology can be found in Appendix B. Generally, the pattern, profile, and dimension were relatively
similar to those values outlined in the design. The Cochran 1b as-built slope (0.0076 ft/ft) was slightly
lower than the design slope of 0.0085; however, the slope falls within the design slope range of 0.0073 –
0.0089. Likewise, the Parrish Branch as-built water surface slope of 0.025 was slightly lower than the
design value of 0.033. However, the as-built value fell within the design slope range of 0.018 – 0.033
listed in the mitigation plan.
Vegetation data, summary tables, and plot photos are located in Appendix C. Results from the initial
survey indicate that planted stem density ranged between 647 and 850 stems per acre with a mean density
of 789 stems per acre across all plots for MY0. A total of nine species were documented across all plots
with species diversity within the plots ranging between three and six. At the time of vegetation data
collection, herbaceous vegetation had begun to establish.
