Please find attached the Uzzle Year 1 Monitoring Report. In Year 1, all four fixed vegetation plots
met the 320 stems per acre success criteria. Five bankfull events were recorded on the stage
recorder on LP1. Groundwater Well 1 recorded a one percent hydroperiod and Groundwater Well
2 recorded a 23 percent hydroperiod. RES expects the groundwater data to improve in following
years when a full water/growing seasons data is reported. There were a few pockets of Chinese
privet re -sprouts observed which will continue to be treated as necessary throughout the
monitoring period.
RES is requesting a 10% stream credit release (287.60 SMUs) for the completion of the Year 1
monitoring report. Please see enclosed the credit release timeline and an updated credit ledger.
Thank you,

Uzzle 1 Year 1 Monitoring Report
Stream Mitigation Site January 2020
1.0 Proiect Summary
1.1 Project Location and Description
The Uzzle Stream Mitigation Site (the Site), a component of the Neu -Con Stream and Wetland Umbrella
Mitigation Bank, is located in Johnston County, North Carolina, approximately six miles southeast of
Clayton. Water quality stressors currently affecting the Site include livestock production, agricultural
production, and improper flow dynamics due to impervious surface runoff. The Site presents 5,897 linear
feet of stream restoration and enhancement generating 2,876 Stream Mitigation Units (SMU) along Little
Poplar Creek and two unnamed tributaries.
The Site is located in the Neuse River Basin within Cataloging Unit 03020201, TLW 03020201100040,
part of the Neuse Regional Watershed Planning (RWP) area, and the Wake -Johnston Collaborative Local
Watershed Plan (WJCLWP). As part of the RWP and WJCLWP, the Site is located in a sub -watershed
identified as High Priority for stream corridor restoration due to current surrounding land use, hydrologic
impairment due to stormwater runoff, and projected impact from highway development.
Originally, consisting of pasture land and wooded areas, the Site's total easement area is 27.3 acres within
the overall drainage area of 1,312 acres. Grazing livestock historically had access to all stream reaches
within the Site and the lack of riparian buffer vegetation, deep-rooted vegetation, and unstable channel
characteristics contributed to the degradation of stream banks throughout the Site. Prior to restoration work,
erosion and aggradation were especially prominent at the upstream end of the Site where Little Poplar Creek
enters via a culvert under HWY US-70.
The stream design approach for the Site was to combine the analog method of natural channel design with
analytical methods to evaluate stream flows and hydraulic performance of the channel and floodplain. The
analog method involves the use of a reference reach, or "template" stream adjacent to, nearby, or previously
in the same location as the design reach. The template parameters of the analog reach are replicated to create
the features of the design reach. The analog approach is useful when watershed and boundary conditions
are similar between the design and analog reaches. Hydraulic geometry was developed using analytical
methods to identify the design discharge.
The Site will be monitored on a regular basis throughout the seven-year post -construction monitoring
period, or until performance standards are met. Upon approval for closeout by the Interagency Review
Team (IRT), the Site will be transferred to the North Carolina Wildlife Habitat Foundation (NCWHF). The
NCWHF will be responsible for periodic inspection of the Site to ensure that restrictions required in the
Conservation Easement or the deed restriction document(s) are upheld. Endowment funds required to
uphold easement and deed restrictions will be negotiated prior to site transfer to the responsible party.
This site is co -located with a DWR Riparian Buffer Bank. The width of the riparian restoration and
enhancement areas where buffer or nutrient offset credits are generated will begin at the most landward
limit of the top of bank and extend landward to a distance of at least 50 feet perpendicular to the streams,
then again 151-200 feet from the top of bank. There will be no overlapping buffer crediting areas with
stream crediting areas between 51-150 feet from the top of bank.
1.2 Project Goals and Objectives
Through the comprehensive analysis of the Site's maximum functional uplift using the Stream Functions
Pyramid Framework, specific attainable goals and objectives will be realized by the Site. These goals
Uzzle 2 Year I Monitoring Report
Stream Mitigation Site January 2020
address the excess nutrient input, streambank erosion, and sedimentation that were identified as major
watershed stressors in the 2010 Neuse RBRP..
The Site goals are:
• Improve water transport from watershed to the channel in a non -erosive manner in a stable
channel;
• Improve water quality within the restored channel reach and downstream water sources by
reducing sediment and nutrient loads, and increasing dissolved oxygen levels;
• Improve flood flow attenuation on -site and downstream by allowing for overbank flows and
connection to the active floodplain; and
• Improve ecological processes by reducing water temperature, improving terrestrial and
aquatic habitat, and restoring a native plant community.
The Site objectives to address the goals are:
• Design and construct stable stream channels with appropriate pattern, dimension, and profile
based on reference reach conditions;
• Permanently exclude livestock from stream channels and their associated buffers;
• Add in -stream structures and bank stabilization measures to protect restored and enhanced
streams;
• Reduce bank height ratios and increase entrenchment ratios to reference reach conditions;
• Maintain and improve forested riparian buffers to at least 50 feet on both sides of the channel
along all reaches with a coastal plain hardwood riparian community;
• Treat exotic invasive species; and
• Establish a permanent conservation easement on the Site.
Limitations to achieving these watershed goals arise by remaining constrained to our Site boundaries.
While we are restoring the habitat and streams to stable and effective conditions that achieve our goals
within the Site parcels, we are unable to influence the effect of poor riparian buffers and livestock impact
in other areas within the watershed. However, through this Site's connectivity with other projects in the
watershed and responsible stewardship of current restoration projects, overall watershed functionality and
health will improve to meet the RBRP goals.
1.3 Project Success Criteria
The Site follows the USACE 2003 Stream Mitigation Guidelines and the "Wilmington District Stream and
Wetland Compensatory Mitigation Update" dated October 24, 2016. Cross section and vegetation plot data
will be collected in Years 0, 1, 2, 3, 5, and 7. Stream and wetland hydrology data and visual monitoring
will be reported annually.
Stream Success Criteria
Four bankfull flow events must be documented within the seven-year monitoring period. The bankfull
events must occur in separate years. Otherwise, the stream monitoring will continue until four bankfull
events have been documented in separate years.
There should be little change in as -built cross -sections. If changes do take place, they should be evaluated
to determine if they represent a movement toward a less stable condition (for example down -cutting or
erosion), or are minor changes that represent an increase in stability (for example settling, vegetative
changes, deposition along the banks, or decrease in width/depth ratio). Cross sections shall be classified
using the Rosgen stream classification method, and all monitored cross -sections should fall within the
quantitative parameters defined for channels of the design stream type. Bank height ratio shall not exceed
Uzzle 3 Year I Monitoring Report
Stream Mitigation Site January 2020
1.2, and the entrenchment ratio shall be no less than 2.2 within restored reaches. Channel stability should
be demonstrated through a minimum of four bankfull events documented in the seven-year monitoring
period.
Digital images will be used to subjectively evaluate channel aggradation or degradation, bank erosion,
success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal images should
not indicate the absence of developing bars within the channel or an excessive increase in channel depth.
Lateral images should not indicate excessive erosion or continuing degradation of the banks over time. A
series of images over time should indicate successional maturation of riparian vegetation.
Vegetation Success Criteria
Specific and measurable success criteria for plant density within the riparian buffers on the Site will follow
IRT Guidance. Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover a minimum
of two percent of the planted area and there will be a minimum of four plots. Vegetation monitoring will
occur between July 1st and leaf drop. The interim measures of vegetative success for the site will be the
survival of at least 320 planted three-year old trees per acre at the end of Year 3, 260 five-year old trees
at the end of Year 5 that are at least 7 feet tall, and the final vegetative success criteria will be 210 trees
per acre with an average height of 10 feet at the end of Year 7. Height measurement success criteria do
not apply to the understory trees or shrubs. Volunteer trees will be counted, identified to species, and
included in the yearly monitoring reports, but will not be counted towards the success criteria of total
planted stems. Additionally, no species may account for over 50 percent of total stems at a given plot.
1.4 Project Components
The Site is comprised of two easement sections, separated by a newly built ford crossing along Little Poplar
Creek. The stream reaches include Little Poplar Creek (LP1, LP2, LP4, LP5, and LP7) and two unnamed
tributaries (LP3 and LP6), split into seven reaches by treatment type and location. The stream mitigation
components are summarized below. Mitigation credits presented below are based upon the Approved
Mitigation Plan. The Project is co -located with a DWR Riparian Buffer Bank. The width of the riparian
enhancement areas where buffer credits are generated begin at the most landward limit of the top of bank
and extend landward to a distance of at least 50 feet perpendicular to the streams and from 151 — 200 feet.
The buffer from 50 — 150 feet is used to generate credit using the non-standard buffer credit calculation.
Therefore, there is no overlap of buffer crediting areas and stream crediting areas.

of the methodology and calculations is described in the Mitigation Plan.
1.5 .S'tream Design/Approach
Stream restoration and enhancement efforts along the tributaries at the Uzzle Stream Mitigation Site were
accomplished through analyses of geomorphic conditions and watershed characteristics. The design
approach applied a combination of analytical and reference reach -based design methods that meet
objectives commensurate with both ecological and geomorphic improvements. For Reach LP1, natural
design concepts were applied and verified through rigorous engineering analyses and modeling. The
objective of this approach is to build a geomorphically stable channel that provides habitat improvements
and ties into the existing landscape.
The Uzzle Stream Mitigation Site has been broken into the following reaches:
Reach LP1 (Priority I Restoration)
Reach beginning downstream of US HWY 70 at the northern project limits flowing south to Reach LP2.
Wooded active pasture was located adjacent to the reach. Priority I Restoration was performed along Reach
LP1 to address channel degradation and bank erosion caused by cattle access and high energy storm flows
from the upstream culvert. The design approach included meandering the channel within the natural valley,
aligning the channel with the upstream culvert, backfilling the existing stream, reconnecting the channel to
its floodplain, and excluding livestock from the stream. A minimum 50-foot buffer was established and
planted with native riparian vegetation. Woody debris and grade control structures were installed along the
bed to improve in -stream habitat and stability. The watershed that drains to the upper end of the project is
approximately 1,124 acres, and land use is primarily agricultural. The drainage area at the downstream end
of the reach is 1,174 acres.
Uzzle 5 Year I Monitoring Report
Stream Mitigation Site January 2020
Reaches LP2, LP3, LP4, LP5, LP6, and LP7 (Enhancement H)
Treatment of these reaches included treatment of invasive vegetation, debris removal, pocketed areas of
supplemental planting, and livestock exclusion. A minimum 50-foot buffer was established along the reach
and was planted with native riparian vegetation where existing vegetation was non-native or limited density.
The drainage area at the downstream end of the reaches is 1,312 acres. A rock ford crossing was constructed
at the crossing in the middle of Reach LP5. Both Reaches LP5 and LP6 right bank have less than 50 feet
buffers, but they run parallel to a 50 feet utility easement corridor that is fully vegetated maintained
herbaceous cover with some foot paths.
1.6 Construction and As Built Conditions
Stream construction and planting was completed in May 2019. The Uzzle Mitigation Site was built to design
plans and guidelines. Project credits are based on design centerline, but as -built stream lengths are shown
on Table 1. The as -built survey was included in the Baseline Monitoring Report and includes a redlined
version.
1.7 Year I Monitoring Performance (MYI)
The Uzzle Year 1 Monitoring (MY1) activities were performed in December 2019. All Year 1 Monitoring
data is present below and in the appendices. The Site is on track to meeting vegetation and stream interim
success criteria.
Ve etg ation
Monitoring of the four permanent vegetation plots was completed during December 2019. Vegetation data
are in Appendix C, associated photos are in Appendix B, and plot locations are in Appendix B. MYI
monitoring data indicates that all plots are exceeding the interim success criteria of 320 planted stems per
acre. Planted stem densities ranged from 688 to 971 planted stems per acre with a mean of 789 planted
stems per acre across the permanent plots. A total of 15 species were documented within the plots.
Volunteer species were noted in one plot, with an average of 40 species per acre. The average stem height
in the vegetation plots was 1.6 feet.
Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is
becoming well established throughout the project. There are a few pockets of Chinese privet that are re -
sprouting in the downstream section of the easement. RES will continue to administer treatments, as
necessary, throughout the monitoring period.
Stream Geomorphology
Geomorphology data for MY1 was collected during December 2019. Summary tables and cross section
plots are in Appendix D. Overall the baseline cross sections and profile on the restoration reach relatively
match the design. The cross sections on the Enhancement II reaches were included to monitor the changes
in dimension post cattle exclusion and riparian planting. This year's conditions show that shear stress and
velocities have been reduced for all restoration/enhancement reaches. All reaches were designed as very
coarse sand bed channels and remain classified as very coarse sand bed channels post -construction.
Visual assessment of the stream channel was performed to document signs of instability, such as eroding
banks, structural instability, or excessive sedimentation. The channel is transporting sediment as designed
and will continue to be monitored for aggradation and degradation.
Uzzle 6 Year I Monitoring Report
Stream Mitigation Site January 2020
Stream Hydrology
The stage recorder on LP1 recorded five bankfull events in MY1. The highest event was 1.21 feet above
the top of bank and occurred in July 2019. There has been at least one bankfull event in on year of
monitoring. The gauge location can be found on Figure 2, a photo is in Appendix B, and the hydrology
data is in Appendix E.
Wetland Hydrology
Two groundwater wells were installed in June 2019 to monitor wetland hydrology in the existing wetland
on site. Groundwater Well 1 recorded a 1% hydroperiod and Groundwater Well 2 recorded a 23%
hydroperiod. RES expects the hydroperiods to increase in future monitoring years when early growing
season data is included. Groundwater well locations can be found on Figure 2 and the data is in
Appendix E.
2.0 Methods
Stream monitoring was conducted using a Topcon GTS-312 Total Station. Three-dimensional coordinates
associated with cross-section data were collected in the field (NAD83 State Plane feet FIPS 3200).
Morphological data were collected at eight cross -sections. Survey data were imported into CAD, ArcGIS®,
and Microsoft Excel® for data processing and analysis. The stage recorder includes an automatic pressure
transducer flow gauge. The flow gauge was installed within the channel and will record water depth at an
hourly interval. A surveyed elevation was recorded at the bed and top of bank at the stage recorder elevation
to detect bankfull events.
Vegetation success is being monitored at four permanent monitoring plots. Vegetation plot 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 are processed using the CVS data entry
tool. In the field, the four corners of each plot were permanently marked with PVC at the origin and metal
conduit at the other corners. Photos of each plot are to be taken from the origin each monitoring year.
Wetland hydrology is monitored to document maintenance of jurisdictional groundwater levels in the
stream restoration area (as requested by NCIRT). This is accomplished with two automatic pressure
transducer gauges (located in groundwater wells) that record daily groundwater levels. One automatic
pressure transducer is installed above ground for use as a barometric reference. Gauges are downloaded
quarterly and wetland hydroperiods are calculated during the growing season. Gauge installation followed
current regulatory guidance. Visual observations of primary and secondary wetland hydrology indicators
are also recorded during quarterly site visits.

Shaded cells indicate that these will typically not be filled in.
* -Reach was split into 4 segments for the purpose of pre-existing data collection.
1 - The distributions for these parameters can include information from both the cross-section measurements and the longitudinal profile. 2 -For projects with a proximal USGS gauge in -line with the project reach (added bankfull verification -rue).
3. Utilizing XS measurement data produce an estimate of the bankfull floodplain area in acres, which should be the area from the top of bank to the toe of the terrace riser/slope.
4 -Proportion of reach exhibiting banks that are eroding based on the visual survey for comparison to monitoring data; 5. Of value/needed only if the n exceeds 3

- Uses the as -built cross sectional area as the basis for adjusting each subsequent years bank -full elevation
- Uses the current years low top of bank as the basis for adjusting each subsequent years bankfull elevation
Note: The smaller the channel the closer the survey measurements are to their limit of reliable detection, therefore inter -annual variation in morphological measurement (as a percentage) is by default magnified as channel size decereases. Some of the variability above is the result of this factor and some is due to the large amount of depositional
sediments observed.
