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 1.4 dated 11/7/11) summarizes data for Year 3 (2014)
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 sinense).
Vegetation success criteria dictate that an average density of 320 stems per acre must be surviving in the
first three monitoring years. Subsequently, 290 stems per acre must be surviving in year 4 and 260 stems
per acre in year 5. Stem counts will be based on an average of the evaluated vegetation plots. Based on
the number of stems counted, average densities were measured at 516 planted stems per acre (excluding
livestakes) surviving in year 3 (2014). In addition, each individual plot met success criteria based on
planted stems with the exception of plot 5, which was 2 stems shy of success with 243 planted stems per
acre. However, when including naturally recruited stems of black walnut (Juglans nigra) and black
locust (Robinia pseudoacacia) plot 5 met success criteria. Plot 5 is adjacent to the unnamed tributary,
which is characterized by dense fescue that may have outcompeted some of the 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 sinense) and Japanese privet (Ligustrum japonicum) 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 (too small to see on figures), and two areas just downstream
Greenbrier Creek (final) Axiom Environmental, Inc. Monitoring Year 3 of 5 (2014)

Alamance and Chatham Counties, North Carolina page 1

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 vimineum) 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.
With the exception of the impounded area, vegetation within the preservation reach is well - established
with scattered occurrences of invasive species. Two small but dense populations of Tree of Heaven
(Ailanthus altissima) were observed on the eastern edge of the preservation reach (Figure 213, Appendix
A). Additionally, 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 3 (2014) 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.
Three bankfull events were recorded during the year 3 (2014) monitoring season for a total of five
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 existing condition BEHI values with 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. One previously noted
beaver dam located at Cross - section 8 was removed, likely during a heavy flow event, and was not
present during monitoring activities. Another previously noted dam located downstream of the Staley
Snow Camp bridge crossing was located and is still intact (Dam 1, Figure 2A, Appendix B). Currently,
one large, well - established impoundment is located on the preservation reach consisting of two major
beaver dams (Dams 2 and 3, Figure 213, Appendix B). 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, which consists of mostly standing water, and no natural recruits are becoming
established at this time. This impoundment area is shown on the Current Conditions Plan View Map
(Figure 213, Appendix B).
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 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

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 3 (2014)
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 Southern and Mid - Atlantic States (Weakley 2012).
2.2 Stream Assessment
Annual stream monitoring was conducted in late February -March 2014. Fourteen permanent cross -
sections, eight riffle and six pool, were established and will be used to evaluate stream dimension;
locations are depicted on Figure 2A (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 floodplain, 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 2A (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 1.0 -1.1, 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.

1 = 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.
2 = The acreage within the easement boundaries.
3 = 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.
4 = 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 Iikley 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 red italics 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.

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/'28/2017. 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

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 l+, 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.

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 suminary 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 dose flow is
maintained. Toni Reeder and Rich Gannon agreed that level spreaders would not necessarily be
needed on EEP buffers in rural areas where dose flow is not an issue. �G"

3. Land Use Change: If EEP purchases agricultural land to dry riparian buffer restoration we believe EEP
should get credit for restoration of the entire buffer w.id#h. That is, the first 50 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
bluffer rules, the EEP is actually implementing an active riparian buffer restoration project on that
land, not simply taking it out of agricultural use. 1=urthennore, if EEP does not purchase these lands,
there will be no land use change.
Tom and Rich agreed with this statement- EEP should get credit for the entire width restored.
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 Jordan rules to erasure the fees are set appropriately and
the requirements (service area) are attainable - This area is likely to have higher implementation
costs and less opportunity for lower cast brr fens as nutrient offset mitigation- IrEFl` ►dill accept
payments in this area. ive roust be able to afford to implement projects.
S. EEP''s Nutrient Offset Accounting Methods: Regarding EEP's nutrient offset requireinetris- Jim
Stanfill discussed how we measure the total pounds for 3 q years when we accept ca nutrient aifsel
p(tvrnent and take can a requirement. Our projects are setup to of vet a tour!,lumb rs ofPannA acrd,
therefore, use may have "shorter" Mess than 30 years) more intense protects. Rich and Tom were in
agreement with our accounting methods.
6, Riparian Buffer Mitigation Site location — clarification of intent of rules: In the Randleman
watershed ('far Cape Pear 03), EEP staf%'have questioned where- upstreaan or downstream- in the
watershed the mitigation should take place, Afifigatron thal EEP already has downstream of the
reservoir can be used, but new pursuits should be upstreona in order to protect the reservoir.
Likewise, in Catawba, new projects should be downstream ofLake James to be used as mitigation
credit_ EEP ,staff also clarified that the rules do not have a time requirement for .EEP to provide the
mil gation, but that the program uses the same bore requirements as the MOU. Torn and Rich were
01sO agreeable to this.
7. Rich requested that EEP allow. for transparencies in its prograin and asked for- ors to provide as much
data as possible in our annual report and work on information to be included on E,EP's Lela site.
EEP agreed and is working tv set up a speck web page at the programs web site devoted to the
lVutrietrt Offset Program,
