Dear Ms. Crocker:
Water & Land Solutions, LLC (WLS) is pleased to present the Final Monitoring Year 1 Report (including
record drawings) for the Buffalo Creek Tributaries Mitigation Project to the North Carolina Department
of Environmental Quality (NCDEQ) Division of Mitigation Services (DMS). Per the DMS review comments,
WLS has updated the Final Monitoring Year 1 Report and associated deliverables accordingly. We are
providing the electronic deliverables via cloud link. The electronic deliverables are organized under the
following folder structure as required under the digital submission requirements:
1. Report PDF

6_Photos
We are providing our written responses to DMS' review comments on the Draft As -Built Baseline Report
below. Each of the DMS review comments is copied below in bold text, followed by the appropriate
response from WLS in regular text:
General:
• Stream flow and wetland gages. For many gages, most of the monitoring year (5 months) is
showing as data malfunctions. Although gages many met within the first month of
monitoring, the entirety of the monitoring year is expected to be captured. Please check and
download data more regularly in the future to avoid this issue. Be advised that in previous
monitoring years the IRT considers malfunction the same as not meeting success. Response:
Gauges are downloaded during quarterly site visits. Lost data was due to a malfunctioning data
shuttle and not a malfunction of the data logger. A malfunction in the data shuttle was an error we
were not aware could occur. Now that we are aware of this potential malfunction, we will be more
diligent in downloading gauge data in the future.

• Provide a photo that shows the additional marking for the encroachment area on MS-R2 in
the subdivisions.In MY2 monitoring report,please provide photos of re-planted area and
conditions.Suggest using larger stock,aesthetically pleasing trees from the mitigation
planting plan. Response: Photos of the encroachment areas are included in e-data.These areas will
be replanted with 1 gallon stock with species from the approved mitigation plan.Photos will be
provided in future reports.
• At the baseline site visit,it was observed in the field that there are some areas of overland
flow into the easement from the High School BMP Pond around R3 (lower).Please describe
condition of this area after MY1 in response or report narrative.Response: Overland flow
occurs near R3 (lower)/upper MS-1 during heavy rain events.Herbaceous vegetation is establishing
well on the stream bank and left buffer area.There were no issues observed during MY1 of sediment
entering the stream. Documentation and photos of this area will be included in future monitoring
reports.
Electronic Comments:
• Please submit a feature characterizing the invasive treatment areas. Response:A shapefile of
the invasive species area is included in the e-data.
Please contact me if you have any questions or comments.

1 Project Summary
1.1 Project Location and Description
The Buffalo Creek Tributaries Mitigation Project ("Project") is a North Carolina Department of
Environmental Quality (NCDEQ), Division of Mitigation Services (DMS) full-delivery stream and wetland
mitigation project contracted with Water& Land Solutions, LLC(WLS) in response to RFP 16-007279.The
Project will provide stream and wetland mitigation credits in the Neuse River Basin (Cataloging Unit
03020201).The project site is in Johnston County, North Carolina, between the Town of Wendell and the
Community of Archer Lodge. The Project is in the Lower Buffalo Creek Priority Sub-watershed
030202011504, study area for the Neuse 01 Regional Watershed Plan Phase II, Final Report(RWP), and in
the Targeted Local Watershed 03020201180050, of the Neuse River Basin.
The Project involved the restoration, enhancement, and preservation of eight stream reaches (MS-R1,
MS-R2, R3 (upper), R3 (lower), R4, R5 (upper), R5 (lower), and R6) with designed totals of approximately
5,029 linear feet of streams.The Project also includes riparian wetland restoration (re-establishment)and
enhancement of approximately 3.495 acres.The Project provides significant ecological improvements and
functional uplift through stream and wetland restoration and will decrease nutrient, and sediment loads
within the watershed. See Section 2 for a detailed benefits summary and Table 1 for a summary of project
assets. Figure la illustrates the project mitigation components.
Prior to construction, many of the existing streams were incised and degraded due to excess bank erosion
and increased stormwater flows.Wetland hydrology was drained across the floodplain and areas mapped
with hydric soils. The existing vegetation within the riparian corridor consists of mixed hardwood forest
with some disturbed pine forest. Adjacent land use consists of agriculture, silviculture, and residential
development.
Monitoring Year 1 (MY1) activities occurred during the second week of November 2021. This report
presents the data for MY1. The Project meets the MY1 success criteria for stream hydrology, stream
horizontal and vertical stability, streambed condition and stability, and vegetation. Stream flow success
criteria was not documented at FG-1 on R4 due to a data download malfunction.Six of the seven wetlands
met success criteria for hydrology. Based on these results,the Project is on trajectory to meet interim and
final success criteria. For more information on the chronology of the project history and activity, refer to
Appendix E. Relevant project contact information is presented in Appendix E and project background
information is presented in Table 3.
1.2 Project Quantities and Credits
The Project mitigation components include a combination of Stream Restoration, Enhancement and
Preservation activities, as well as Riparian Wetland Re-establishment and Enhancement, as summarized

2 Goals, Performance Criteria, and Functional Improvements
2.1 Project Goals and Objectives
The Project will meet the goals and objectives described in the Buffalo Creek Tributaries Final Approved
Mitigation Plan and will address general restoration goals and opportunities outlined in the DMS Neuse
River Basin Watershed Restoration Priorities (RBRP). More specifically, three out of the four functional
goals and objectives outlined in the Wake-Johnston Collaborative Local Watershed Plan (LWP) as well as
the Neuse 01 RWP will be met by:
• Reducing sediment and nutrient inputs to the Buffalo Creek Watershed.
• Restoring, preserving, and protecting wetlands, streams, riparian buffers and aquatic habitat.
• Implementing stream restoration in rural catchments together as "project clusters."
To accomplish these project-specific goals,the following objectives will be measured to document overall
project success:
• Restore stream and floodplain interaction and geomorphically stable conditions by reconnecting
historic flow paths and promoting more natural flood processes;
• Improve and protect water quality by reducing streambank erosion, nutrient and sediment inputs;
• Restore and protect riparian buffer functions and habitat connectivity in perpetuity by recording
a permanent conservation easement; and
• Incorporate water quality improvement features to reduce nonpoint source inputs to receiving
waters.

2.2 Project Success Criteria
The success criteria for the Project will follow the approved performance standards and monitoring
protocols from the final approved mitigation plan; which was developed in compliance with the USACE
October 2016 Guidance, USACE Stream Mitigation Guidelines (April 2003 and October 2005), and 2008
Compensatory Mitigation Final Rule. Cross-section and vegetation plot data will be collected in Years 0, 1,
2, 3, 5, and 7. Stream hydrology data and visual monitoring will be reported annually. Specific success
criteria components and evaluation methods are described below.
2.2.1 Streams
Stream Hydrology: Four separate bankfull or over bank events must be documented within the seven-year
monitoring period and the stream hydrology monitoring will continue until four bankfull events have been
documented in separate years. Stream hydrology monitoring will be accomplished with pressure
transducers installed in pools and correlating sensor depth to top of bank elevation (see appendix D for
installation diagrams). Recorded water depth above the top of bank elevation will document a bankfull
event.The devices will record water depth hourly and will be inspected quarterly.
4 MY1 FINAL Buffalo Creek Tributaries
DMS Project# 100042

The stage recorders include an automatic pressure transducer (HOBO Water Level (13 ft) Logger) set in
PVC piping in the channel. The elevation of the bed and top of bank at each stage recorder location will
be recorded to be able to document presence of water in the channel and out of bank events. Visual
observations (i.e. wrack or debris lines) and traditional cork crest gauges will also be used to document
out of bank events.
Stream Profiles, Vertical Stability,and Floodplain Access: Stream profiles,as a measure of vertical stability
and floodplain access will be evaluated by looking at Bank Height Ratios (BHR). In addition, observed
bedforms should be consistent with those observed for channels of the design stream type(s). The BHR
shall not exceed 1.2 along the restored Project stream reaches. This standard only applies to restored
reaches of the channel where BHRs were corrected through design and construction. Vertical stability will
be evaluated with visual assessment, cross-sections and, if directed by the IRT, longitudinal profile.
Stream Horizontal Stability:Cross-sections will be used to evaluate horizontal stream stability on restored
streams. There should be little change expected in as-built restoration cross-sections. If measurable
changes do occur, they should be evaluated to determine if the changes represent a movement toward a
more unstable condition (e.g., downcutting, erosion) or a movement towards increased stability (e.g.,
settling, vegetation establishment, deposition along the streambanks, 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.
Stream cross-section monitoring will be conducted using a Topcon Total Station. Three-dimensional
coordinates associated with cross-section data will be collected in the field (NAD83 State Plane feet FIPS
3200). Morphological data will be collected at 13 cross-sections. Survey data will be imported into
Microsoft Excel® and the DMS Shiny App for data processing and analysis.
Reference photo transects will be taken at each permanent cross-section. Lateral photos should not
indicate excessive erosion or continuing degradation of the stream banks. Photographs will be taken of both
streambanks at each cross-section. A survey tape stretched between the permanent cross-section
monuments/pins will be centered in each of the streambank photographs. The water elevation will be
shown in the lower edge of the frame, and as much of the streambank as possible will be included in each
photo. Photographers will attempt to consistently maintain the same area in each photo over time.
Streambed Material Condition and Stability: Streambed material should not significantly change over
time and any significant changes (e.g., aggradation, degradation, embeddedness) will be noted after
stream bank vegetation becomes established and a minimum of two bankfull flows or greater have been
documented. If significant changes are observed within stable riffles and pools, additional sediment
transport analyses may be required.
Jurisdictional Stream Flow:Monitoring of stream flow will be conducted to demonstrate that the restored
stream systems classified as intermittent exhibit surface flow for a minimum of 30 consecutive days
throughout some portion of the year during a year with normal rainfall conditions. Stream flow monitoring
will be accomplished with pressure transducers installed in pools and correlating sensor depth to the
downstream top of riffle elevation (see appendix D for installation diagrams). If the pool water depth is at
or above the top of riffle elevation,then the channel will be assumed to have surface flow.The devices will
record water elevation twice per day and will be inspected quarterly to document surface hydrology and
provide a basis for evaluating flow response to rainfall events.

2.2.2 Wetlands
Wetland Hydrology:The performance standard for wetland hydrology will be 12 percent based on the
suggested wetland saturation thresholds for soils taxonomic subgroups.The proposed success criteria for
wetland hydrology will be when the soils are saturated within 12 inches of the soil surface for 12 percent
(27 days) of the 227-day growing season (March 21st through November 3rd) based on WETS data table
for Johnston County, NC. The saturated conditions should occur during a period when antecedent
precipitation has been normal or drier than normal for a minimum frequency of 5 years in 10 (USACE,
2005 and 2010b). Precipitation data will be obtained from an on-site rain gauge, installed at the Odell's
House Mitigation Project, and the Clayton (CLAY) Research Weather Station, approximately nine miles
southeast of the Project site. If a normal year of precipitation does not occur during the first seven years
of monitoring,WLS will continue to monitor the Project hydrology until the Project site has been saturated
for the appropriate hydroperiod. If rainfall amounts for any given year during the monitoring period are
abnormally low, reference wetland hydrology data will be compared to determine if there is a correlation
with the weather conditions and site variability.
Wetland hydrology will be monitored to document success in wetland restoration and enhancement areas
where hydrology was affected. This will be accomplished with automatic pressure transducer gauges
(located in groundwater wells) that record daily (twice per day) groundwater levels. The pressure
transducer gauges are HOBO Water Level (13ft) Loggers made by Onset. Seven gauges will be installed
within the wetland crediting areas. One automatic pressure transducer will be installed above ground for
use as a barometric reference. One rain gauge will be installed at the adjacent Odell's House Mitigation
Project site (0.3 miles southeast of the project) to document rainfall at the project. Gauges are
downloaded quarterly and wetland hydroperiods are calculated during the growing season. Gauge
installation will follow current regulatory guidance. Gauge data is downloaded using a HOBO Onset
Waterproof Shuttle Data Transporter. Visual observations of primary and secondary wetland hydrology
indicators will also be recorded during quarterly site visits.
2.2.3 Vegetation
Vegetation monitoring will occur in the fall each required monitoring year, prior to leaf drop. Plots will be
monitored in years 1, 2,3,5,and 7.Vegetative success for the Project during the intermediate monitoring
years will be based on the survival of at least 320,three-year-old trees per acre at the end of Year 3 of the
monitoring period; and at least 260, five-year-old, trees per acre that must average seven feet in height
at the end of Year 5 of the monitoring period. The final vegetative restoration success criteria will be
achieving a density of no less than 210,seven-year-old stems per acre that must average ten feet in height
in Year 7 of monitoring. Volunteer species on the approved planting list that meet success criteria
standards will be counted towards success criteria.
Vegetation success is being monitored at a total of six permanent vegetation plots (10m x 10m or 20m x
5m) and two random vegetation transects (50m x 2m). 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 will be processed using the DMS ShinyApp. For each
plot,the origin will be marked with a PVC pole and the other three corners marked with rebar.Tree species
and height will be recorded for each planted stem and photos of each plot are to be taken from the origin
each monitoring year.

2.2.4 Visual Assessment
WLS will conduct visual assessments in support of mitigation performance monitoring. Visual assessments
of all stream reaches will be conducted twice per monitoring year with at least five months in between
each site visit for each of the seven years of monitoring. Photographs will be used to visually document
system performance and any areas of concern related to streambank and bed stability, condition of in-
stream structures,channel migration, active headcuts, live stake mortality, invasive plant species or animal
browsing, easement boundary encroachments, and general streambed conditions. Permanent photo
points will be at the cross-sections and culvert crossings.
3 Project Attributes
3.1 Design Approach
The Project stream design approach included a combination of Stream Restoration, Enhancement Level I,
and Preservation activities (Table 1). A Priority Level I restoration approach was incorporated with the
design of both a single-thread meandering channel along the main stem (MS-R1 and MS-R2) and step-
pool channels(R3, R4, R5 and R6).All non-vegetated or disturbed areas within the conservation easement
were planted with native species vegetation and any areas of invasive species were removed and/or
treated.

4 Monitoring Year 1 Assessment and Results
The dates of Year 1 monitoring activities are detailed in Appendix E.All year 1 monitoring data is presented
in this report and in the appendices.The Project is on track for meeting stream, wetland, and vegetation
interim success criteria. All monitoring device locations are depicted on the CCPV(Figure la-c).
4.1 Morphological Assessment
Morphological data for the as-built profile was collected in November 2021. Refer to Appendices A and C
for summary data tables, morphological plots, and stream photographs.
4.1.1 Stream Horizontal Pattern & Longitudinal Profile
The MY1 visual observations of stream horizontal pattern and longitudinal profiles closely match the
design parameters and did not show any significant deviation from as-built conditions.The minor channel
adjustments in riffle slopes, pool depths and pattern do not present a stability concern or indicate a need
for remedial action and will be assessed visually during the annual assessments.
4.1.2 Stream Horizontal Dimension
The MY1 channel dimensions generally match the design parameters and are within acceptable and stable
ranges of tolerance. Thirteen cross-sections are located in restoration and enhancement reaches across
the project. Of the thirteen cross-sections, nine are located in riffles and four are located in pools. All
thirteen cross-sections show little change in bankfull area, and all bank height ratios are less than 1.2. It
is expected over time that some pools may accumulate fine sediment and organic matter, however, this
is not an indicator of channel instability. Maximum riffle depths are also expected to fluctuate slightly
throughout the monitoring period as the channels adjust to new flow regime.
4.2 Stream Hydrology
4.2.1 Stream Flow
Two pressure transducers (flow gauges) were installed in March and April 2021 on reaches R4 and R6 to
document baseflow conditions. The flow gauge locations are within the upper one-third of the project
reaches as shown on the CCPV. FG-2 (R6) exhibited a maximum consecutive flow of 45 days between
March 3rd, 2021 and April 17th, 2021, with a cumulative total of 69 days of flow and 182 days of no flow
during MY1 (Appendix D). FG-1 (R4) exhibited a maximum consecutive flow of 11 days between June 3rd
2021 and June 14th, 2021, with a cumulative total of 20 days of flow and 28 days of no flow during MY1.
FG-1 lost data from July 13th'2021 to November 9th, 2021 due to a malfunctioning HOBO Onset Waterproof
Shuttle Data Transporter. FG-1 will be monitored closely in MY2 and is expected to meet criteria when a
full year of data is collected. Additionally, to determine if rainfall amounts are normal for the given year,
precipitation data was obtained from a rain gauge installed at Odell's House Mitigation Project (DMS
#100041) less than a mile south of the Project site.
4.2.2 Bankfull Events
One crest gauge was installed in March 2021 to document bankfull events. WLS installed a conventional
cork crest gauge, along with a pressure transducer to validate flood status MS-R2. During MY1, bankfull
events were recorded on the pressure transducer crest gauge.CG-1 recorded four events with a maximum
event of 1.06 feet above bankfull on June 6th, 2021.Additionally,the cork crest gauge located adjacent to
the pressure transducer confirmed at least one bankfull event.

4.3 Wetlands
Seven wetland groundwater wells were installed in March and April 2021 to monitor wetland hydrology.
Wetland groundwater well locations are shown on the CCPV. During MY1, six of the seven wetland
groundwater wells met the twelve percent wetland hydrology criteria. GW-1 did not meet hydrology
criteria and had a hydroperiod of 2.2 percent during MY1. GW-1 (W1), GW-2 (W1), and GW-3 (W1) lost
data from July 13th, 2021 to November 9th, 2021 due to a malfunctioning HOBO Onset Waterproof
Shuttle Data Transporter. GW-1 had no obvious or apparent reason to not meet success criteria, other
than potential recharge in Year 1. GW-1 will be monitored closely in MY2 and is expected to meet
hydrologic criteria when a full growing season worth of data is collected.
4.4 Vegetation
Monitoring of the six permanent vegetation plots and two random transects was completed during
November 2021. Vegetation data and photos can be found in Appendix B. The MY1 average planted
density is 510 stems per acre, which exceeds the interim measure of vegetative success of at least 320
planted stems per acre at the end of the third monitoring year. All vegetation plots meet the interim
measure requirements and have 364-648 stems per acre. Volunteer species were not noted at baseline
monitoring but are expected to establish in the future.
Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation
is becoming well established throughout the project.
Two encroachments (-0.014 acres) were noted near the southern most culvert crossing on MS-R2. Both
are recently sodded/planted grassy areas adjacent to recent home construction. To prevent further
encroachment, the homeowners were contacted, and the easement line was more clearly marked.
Encroachment planting will occur in early MY2, and actions taken will be documented in the MY2 report.
Small populations of Chinese privet (Ligustrum sinense) were noted within the easement during MY1.
Larger privet was cut mechanically with a brush cutter and smaller privet were treated with foliar spray.
See table below for treatment information.
Invasive Date Treatment
Monitoring Year Targeted Invasive Treatment Conducted Herbicide Used

Cross-Section 13(Pool-MS-R2) The above morphology parameters reflect the 2018 guidance that arose from the mitigation technical workgroup consisting of DMS,the IRT and industry mitigation providers/practitioners.The
outcome resulted in the focus on three primary morphological parameters of interest for the purposes of tracking channel change moving forward.They are the bank height ratio using a constant
MVO MY1 MY2 MY3 MY5 MY7 MY+ As-built bankfull area and the cross sectional area and max depth based on each years low top of bank These are calculated as follows:
Bankfull Elevation(ft)-Based on AB-Bankfull'Area 251.18 250.68 1-Bank Height Ratio(BHR)takes the As-built bankful area as the basis for adjusting each subsequent years bankfull elevation.For example if the As-built bankfull area was 10 ft2,then the MY1
Bankfull elevation would be adjusted until the calculated bankfull area within the MY1 cross section survey=10 ft2.The BHR would then be calculated with the difference between the low top of
Bank Height Ratio_Based on AB Bankfull'Area 0.96 1.06 bank(LTOB)elevation for MY1 and the thalweg elevation for MY1 in the numerator with the difference between the MY1 bankfull elevation and the MY1 thalweg elevation in the denominator.
Thalweg Elevation 247.57 245.52 This same process is then carried out in each successive year.
2-LTOB Area and Max depth-These are based on the LTOB elevation for each years survey(The same elevation used for the LTOB in the BHR calculation).Area below the LTOB elevation will be
LTOB Elevation 251.05 251.01 used and tracked for each year as above.The difference between the LTOB elevation and the thalweg elevation(same as in the BHR calculation)will be recroded and tracked above as LTOB max
