1.0 EXECUTIVE SUMMARY
The Greenbrier Stream Restoration Site (Site) is situated within the United States Geological Society
(USGS) hydrologic unit 03030003 and North Carolina Division of Water Quality (NCDWQ) Priority
Sub -basin 03 -06 -12 The Site is located approximately 8 miles north of Siler City at the crossing of
Staley -Snow Camp/Pleasant Hill Church Road over Greenbrier Creek The Site is encompassed within a
50 48 acre easement located in three parcels, individually owned by Jerrold Murchison (32 94 acres),
Charles Cheek (0 52 acres), and Larry Matthews (17 02 acres) Primary land uses were active row crop
production on the Murchison parcel and active pasture on the Matthews /Cheek parcels Project streams,
Greenbrier Creek and an Unnamed Tributary (UT) to Greenbrier Creek, became impaired from poor land
management, stream dredging, upstream disturbances, and human impacts This report (compiled based
on North Carolina Ecosystem Enhancement Program (EEP)'s Procedural Guidance and Content
Requirements for EEP Monitoring Reports Version 14 dated 11/7/11) summarizes data for Year 2 (2013)
annual monitoring
The project goals are to
• Improve water quality by reducing nutrient loading from a livestock operation in a water supply
watershed
Reduce the high level of sediment loading to the stream from steep, eroding banks
improve both aquatic and terrestrial riparian buffer habitat
These goals will be accomplished through the implementation of the following objectives
• Preservation and protection of important wetlands and stream channel reaches upstream of the
Matthews property
• Improvement of water quality (reduction of nutrient and sediment inputs) by creating a vegetated
riparian buffer filter strip between the stream and livestock operations currently on the property
• Reduction of high sediment loads in the stream through stabilization of eroding channel banks
• Improvement of deteriorated aquatic habitat by reduction of nutrient and sediment loads in the
streams, providing more variable stream channel geometry and creating more opportunities for
carbon inputs from trees in the restored buffer zone
• Improvement of terrestrial habitat through restoration of diverse native woody vegetation in the
riparian buffer zone and control of invasive Chinese privet (Ligustrum smense)
During Year 2 (2013) monitoring, twelve (12) vegetation plots were sampled Ten (10) of the twelve (12)
plots met or exceeded the success criteria of 320 stems /acre (minimum stem count after 3 years) The two
plots below success criteria (plots 5 and 6) had 243 and 283 stems per acre, respectively However, when
including naturally recruited stems of black walnut (Juglans nigra), plot 6 exceeds success criteria Plots
5 and 6 are adjacent to the unnamed tributary, which is characterized by dense fescue that may be
outcompeting planted bare root seedlings Supplemental planting at the Site occurred on February 13 and
14, 2012, in response to the contractor's vegetation warranty assessment (Appendix F) During this
effort, 1952 bare root and 1 gallon trees were planted at the Site Supplemental planting appears to have
resulted in vegetative success across the majority of the Site
Chinese privet (Ligustrum smense) and Japanese privet (Ligustrumjapomcum) are scattered throughout
the site, however, several occurrences (two areas upstream of the confluence, one smaller area along the
easement boundary downstream of the bridge, and one area just downstream of the ford (near cross -
section 12) are particularly dense (Figure 2A, Appendix B) In addition, scattered stems of Bradford pear
(Pyrus calleryana) and multiflora rose (Rosa multiflora) are present in minimal numbers within the Site
Herbaceous species including Japanese stiltgrass ( Microstegium vimmeum) and fescue (Festuca sp ) are
found across the entire Site Microstegium is found in portions of the Site that are covered by mature

canopy along the upstream portion of the unnamed tributary, downstream portions of Greenbrier Creek,
and throughout the preservation reach Fescue is found in open areas previously maintained as pasture,
these areas appear to have poor planted stem survival
With the exception of the previously impounded area, vegetation within the preservation reach is well -
established with scattered occurrences of invasive species Japanese honeysuckle (Lonicera japonica),
Chinese privet (Ligustrum sinense), and microstegium ( Microstegium vimineum) were observed scattered
throughout the reach
A visual assessment and geomorphic survey were completed for the Site, and indicated that the project
reaches were performing within established success criteria ranges as shown below Due to contracting
issues, no baseline data was collected for this project Although there are no baseline cross - sections to
compare with Year 2 (2013) measurements, the Year 1 (2012) cross - sections should serve as an adequate
baseline No significant bank erosion was recorded In addition, no significant aggradation or
degradation of the bed was noted
One bankfull event was recorded during the year 2 (2013) monitoring season for a total of two bankfull
events with one occurring each monitoring year
Stream Success Criteria (from approved Restoration Plan 2008)
• Success is defined as the documentation of no substantial aggradation or degradation of the
channel or banks
Downcutting, deposition, bank erosion, and an increase in sands or finer substrate material must
be documented for assessment by the regulatory agencies
Comparison of the existing conditions BEHI values with the BEHI values computed after
vegetation is established will indicate bank stabilization trajectories
A minimum of two bankfull events must occur in separate years within the five -year monitoring
Beaver have been an ongoing issue on the Site and are being closely monitored Three previously noted
beaver dams located 1) downstream of the Staley Snow Camp bridge crossing, 2) at Cross - section 12, and
3) at Cross - section 13 were removed by APHIS in May 2013 and were not present during monitoring
activities Currently, one large, well - established impoundment is located on the preservation reach
consisting of several beaver dams One large dam was destroyed in the summer of 2013, but it appears as
though the beaver are still active in this area Few woody stems are surviving in the impoundment
footprint, and no natural recruits are becoming established at this time This impoundment area is shown
on the Current Conditions Plan View Map (Figure 2B)
Summary information /data related to the occurrence of items such as beaver or encroachment and
statistics related to performance of vanous project and monitoring elements can be found in tables and
figures within this report's appendices Narrative background and supporting information formerly found
in these reports can be found in the Baseline Monitoring Report (formerly Mitigation Plan) and in the
Mitigation Plan (formerly the Restoration Plan) documents available on EEPs website All raw data

2.0 METHODOLOGY
2.1 Vegetation Assessment
Twelve vegetation plots were established and marked after construction with four -foot metal U -bar post
demarking the corners with a ten foot, three - quarter inch PVC at the origin The plots are 10 meters

square and are located randomly within the Site These plots were surveyed in July for the Year 2 (2013)
monitoring season using the CVS -EEP Protocol for Recording Vegetation, Version 4 2 (Lee et al 2008)
(http: / /cvs.bio unc edu /methods htm), results are included in Appendix C The taxonomic standard for
vegetation used for this document was Flora of the Carolinas, Virginia, Georgia, and Surrounding Areas
(Weakley 2007)
2.2 Stream Assessment
Annual stream monitoring was conducted in May 2013 Fourteen permanent cross - sections, eight riffle
and six pool, were established and will be used to evaluate stream dimension, locations are depicted on
Figure 2 (Appendix B) Cross - sections are permanently monumented with 4 -foot metal garden posts at
each end point Cross - sections will be surveyed to provide a detailed measurement of the stream and
banks including points on the adjacent floodplam, top of bank, bankfull, breaks in slope, edge of water,
and thalweg Data will be used to calculate width -depth ratios, entrenchment ratios, and bank height
ratios for each cross - section in addition, photographs will be taken and pebble counts will be conducted
at each permanent cross - section location annually
Two monitoring reaches were established (the unnamed tributary and Greenbrier Creek) and will be used
to evaluate longitudinal profile, locations are depicted on Figure 2 (Appendix B) Longitudinal profile
measurements will include average water surface slopes and facet slopes and pool -to -pool spacing
Measurements of channel pattern (belt - width, meander length, and radius of curvature) was proposed for
Year 1 (2012), however, the design channel was developed at a sinuosity of 10, resulting in no
measurable meander bends, belt widths, or radius of curvature Two crest gauges were installed onsite,
one on the unnamed tributary and one on Greenbrier Creek, upstream of the confluence These will be
used to document bankfull events throughout the monitoring period Additionally, thirty-one permanent
photo points were established throughout the restoration reach (14 cross - sections, 12 vegetation plots, and
5 fixed station photos) Photographs are included in the Appendices

= Enter the planted acreage within the easement. This number is calculated as the easement acreage minus any existing mature tree stands that were not subject to supplemental planting of the understory, the channel acreage,
crossings or any other elements not directly planted as part of the project effort.
= The acreage within the easement boundaries
= Encroachment may occur within or outside of planted areas and will therefore be calculated against the overall easement acreage. In the event a polygon is cataloged into items 1, 2 or 3 in the table and is the result of encroachment,
the associated acreage should be tallied in the relevant item (i.e., item 1,2 or 3) as well as a parallel tally in item 5.
= Invasives may occur in or out of planted areas, but still within the easement and will therefore be calculated against the overall easement acreage. Invasives of concern /interest are listed below. The list of high concern spcies are those
with the potential to directly outcompete native, young, woody stems in the short-term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established tree /shrub stands over timeframes that are
slightly longer (e.g. 1 -2 decades). The low /moderate concern group are those species that generally do not have this capacity over the timeframes discussed and therefore are not expected to be mapped with regularity, but can be mapped,
if in the judgement of the observer their coverage, density or distribution is suppressing the viability, density, or growth of planted woody stems. Decisions as to whether remediation will be needed are based on the integration of risk factors
by EEP such as species present, their coverage, distribution relative to native biomass, and the practicality of treatment. For example, even modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control,
but potentially large coverages of Microstegium in the herb layer will not likley trigger control because of the limited capacities to impact tree /shrub layers within the timeframes discussed and the potential impacts of treating extensive
amounts of ground cover. Those species with the "watch list" designator in gray shade are of interest as well, but have yet to be observed across the state with any frequency. Those in are of particular interest given their extreme
risk /threat level for mapping as points where isolated specimens are found, particularly ealry in a projects monitoring history. However, areas of discreet, dense patches will of course be mapped as polygons. The symbology scheme below
was one that was found to be helpful for symbolzing invasives polygons, particulalry for situations where the conditon for an area is somewhere between isolated specimens and dense, discreet patches. In any case, the point or
polygon /area feature can be symbolized to describe things like high or low concern and species can be listed as a map inset, in legend items if the number of species are limited or in the narrative section of the executive summary.

Re Greenbrier Creek Stream Restoration Site
SCO # 0406210 -02
Vegetation Warranty items
Dear Ms Cheatham
As stated in the November 8, 2011 letter addressed to you from Ed Hajnos, portions the Greenbrier
Creek project site did not meet the vegetation warranty as stated in contract documents. As per
SCO contract 0406210 -02 Special Provision Section 6 0, bare roots were to be planted at 680 stems
per acre, and containerized seedlings at 435 per acre, of those 80% minimum were to survive for
one year from Project Acceptance The warranty period began 2/28/2019 and will expire
2/28/2012
Field data is summarized below and supplemental information about replant requirements is
attached.
Vegetation assessment methodology
Planted vegetation at the Greenbrier Creek site has been assessed once since February 2011 project
planting, on September 28, 2011 by the Owner. Data collected during the sampling effort report
higher plant mortality than contractually permissible Warranty replant numbers are based on the
data collected Field methodology and data are described below
September 28, 2011 sampling
Fourteen (14) vegetation plots were established, each 1,076 sq ft (25m x 4m) in Zone 4 of the
original planting plan All planted bare root and shrubs present within the plot were counted
towards the warranty criteria, including those that were top -dead but were re- sprouting at their
base. Given 680 stems were planted per acre, 544 per acre were required to survive 1 year, or 13

Two vegetation plots were established, each 1,076 sq ft (25m x 4m) in Zone 5 of the original
planting plan. All containerized seedlings present within the plot were counted towards the
warranty criteria, including those that were top -dead but were re- sprouting at their base. Given
435 stems were planted per acre, 348 per acre were required to survive 1 -year, or 9 per plot to
meet the 100% warranty Two (2) sample plots did not meet the survival criteria (Vegetation

In general, some of plant survival in the Zone 4 and Zone 5 planting zones did not meet the
warranty requirement The table below outlines necessary replanting areas Surviving stems were
subtracted from the warranty criteria (544 /acre for Zone 4 and 348 per acre for Zone 5) so that the
"Total plants needed" column is the number of remaining stems needed get warranty criteria
(544/348) stems per acre in areas with deficient vegetation Planting densities were averaged into
planting zones and are identified on the attached Supplemental Planting Map.

Instructions
• The Supplemental Planting effort needs to be coordinated with EEP so we can arrange with
the landowner to be on site
• All replant materials must conform to the original project specification (dormant season
planting, species composition, size, vigor, etc )
• The Supplemental Planting effort must take place in the dormant season for Alamance
County, (December 1 -April 1).
• No planting shall be done when the temperature is below 320 F, when the soil to be
excavated for the plant hole is frozen, when the sides or bottom o the plant hole are frozen,
or when the soil is too wet

Although the warranty for this project doesn't expire until February 28, 2012, EEP does not intend
to reassess the site again for additional warranty compliance. Plants installed during the warranty
replant will not have a warranty place on them. Once Carolina Environmental Contracting, Inc.
complies with this replanting, a Satisfaction Letter will be awarded.
If you disagree with this finding or have any questions, please contact me directly.

SUBJECT June 12, 2007 EEP Nutrient Offset meeting summary
This correspondence is provided to summarize our June 12, 2007 meeting with you, Tom Reeder,
Suzanne Klimek, Jim Stanfill and myself The meeting was held in an attempt to clarify some issues
related to EEP's use of riparian buffers to mitigate for Nitrogen and Phosphorus It is important to come
to a common understanding on these issues related to nutrient offset mitigation credit generation as we
plan the implementation of mitigation projects. Below are the topics we discussed as they were presented
in our May 14, 2007 letter to you A summary of our discussions is below each topic in italics We invite
your input and response to ensure we have captured our discussions accurately
Riparian Buffer N Reduction Efficiencies. With regard to the January 4, 2007 report detailing your
discussions of NO3 — N reduction, we would like to clarify whether the benefits of land use change
and the benefit of periodic overbank flooding have been considered in the buffer efficiency
calculations. We also want to discuss EEP's buffer widths and the efficiencies that should be used for
buffers 100 feet or greater A 50% efficiency was and is used in our calculations of buffer efficiency
for our offset projects Our projects typically have 200 foot buffer widths
The underlying questions here were — Can EEP get more credit for buffers that are wider than 50 feet
by using higher efficiency rates as shown in the NLEW paper? As a group we agreed to use an
overall efficiency of 50% for riparian buffers used to offset nutrients regardless of width Rich
Gannon noted that although higher efficiencies were suggested in the "NLEW" paper for buffers
wider than 50 feet, these numbers are not widely verified It is therefore appropriate to use 50% to
determine reductions Jim Stanfill agreed noting that EEP buffers are often 200 feet wide and
although using a higher efficiency would generate greater mitigation credit, the 50 % number had
been used up to this point and EEP would continue to use that to calculate credits
2 Level Spreaders The use of level spreaders on riparian buffers not subject to concentrated flow
needs to be discussed It is our understanding that guidance on level spreaders may only be meant to
apply to those riparian buffers being used as "onsite" treatment BMPs by permitees We assume the
guidance does not apply to riparian buffer restoration as typically done by EEP, but would like to
discuss and get clarification on that issue
The standard is to provide dose flow through buffers Because EEP would often need to actually
clear portions of riparian buffers to install level spreaders, and also because EEP's buffers are often
200 feet wide, we do not think the use of level spreaders is necessary as long as die flow is
maintained Tom Reeder and Rich Gannon agreed that level spreaders would not necessarily be
needed on EEP buffers in rural areas where d ffuse flow is not an issue YWA

3. Land Use Change- If EEP purchases agricultural land to do riparian buffer restoration we believe EEP
should get credit for restoration of the entire buffer width That is, the first 40 feet of buffer would
not be excluded from our credit calculations The argument for this is that while the act of EEP
purchasing the-property may have changed a property's land use and', therefore; made -it subject to the
buffer rules, the EEP is actually implementing an active riparian buffer restoration project on that
land, not simply taking it out of agricultural use Furthennore, if EEP does not purchase these lands,
there will be no land use change
Torn and Rich agreed with this statement- EEP should get credit for the ealir e, width t estored
We also have some questions about the Jordan nutrient offset trading; program, but staff are still
reviewing the information that has been released.
EEP will need to provide comments on the Jordwi rules to ensure the fees are set capproprtately and
the requirements (service area) are attainable `flits area,is hkely to have ltigher,implementation
costs and less opportwitty for lower cost buffers as nutrient offset innigation ff JEEP will accept
payments in thit area, we initst be able to afford to unplement projects
S EEP's Nutrient Offset Accounting Methods, Regarding EEP's mdrient offset requirements - Jun
Stanfill discussed how we measure the lolal pounds for 30 years when ive accept a trulrient offset
perymeni and take on a requirement Our projects are .Yet up to offset a total numbers rf pounds and,
therefore. we may have "shorter" (less than 30 years) more intense projects. Rich and 'font were in
agreement with Our accounting nielhas
6 Riparian Buffer Mitigation Site location — clarification of intent of rules: fn the Randleman
watershed (for Cape Fear 03), EEP staff have questioned inhere- upstream or down streattt- rn the
watershed the mitigation should take place Xhligatton that EEP already has dmvneream of the
reservoir can be used but new pursuits should he upstream in Larder to protect the reservoir
Likewise, ur Catativba neiv projects should be downstream of Lake Jantes to be used as mitigation
credit EEP .Staff also clay f ed drat the rules do not have a tune requireinent for EEP to provide the
mitigation- but that the program uses the .same time requrreinents as the WOU. Tom und'Rich were
calsv agreeable to this
i Rrch requested that EEP allow for transparencies in its program and asked for us to provide as inuch
data as possible in our annual report and work on information to be mciuded an EEPs Web site
EEP agreed and is workitig to set up a specV4, web page at the program 's web site devoted to the
l+utrwnt Offset Prograin
Thank, you for taking the time to discuss these issues with us. If you need additional mforination or want
to offer corrections or clarifications to the information presented herein, please contact Kelbv Williams at
