RE: Dairyland Year 5 Monitoring Report (SAW-2016-01258)
Kim,
Please find attached the Dairyland Year 5 Monitoring Report. All of the 11 fixed vegetation plots met the
260 stems per acre success criteria and three out of the four random vegetation plots met the 260 stems
per acre success criteria. There were zero stream problem areas in Year 5. The average stems per acre across
the plots was 585 and the average stem height was 9.8 feet. RES plans to replant the 0.17 acres of Year 5
bare areas and low stem density areas this dormant season. During monitoring in August Chinese privet
(Ligustrum sinense) and a patch of Tree of Heaven (Ailanthus altissima) was noted along the edge of the
Enhancement II portion of the project. Both species will be treated during the dormant season.
Encroachment has been successfully reduced with the planting of trees to block the road running through
the preservation area. Additionally, the trash pile that was adjacent to the road has been removed, seeded
with an herbaceous mix, and planted with 3-gallon container trees. No additional areas of encroachment
were noted during MY5 monitoring events. Both woody and herbaceous vegetation are becoming well
established. Reach HB-2 had four bankfull events, Reach UT-2 had 13 bankfull events, and UT-2 documented
80 consecutive days of flow.
Year 3 credit release letter comments and responses: Comments from previous YR3 Monitoring report are
included below:
1. Regarding this report, DWR is most concerned about the new encroachment. In addition to
signage and horse tape, DWR requires raking in native seed and planting woody stems within
the cleared area to mitigate its appearance as a road.
The road has been blocked off by a row of planted trees. RES has plans to re -survey the
easement line and install additional signage. Seeding of the road will occur this Fall.
2. DWR appreciated report photos and detailed callouts on the CCPV. It would've been helpful to
also callout the headcut repair; please provide a stabilization status for this repair in the MY5
report.
The headcut repair has blown out since its installation. The damage will be repaired in the fall of
2023. See photos in Appendix B.
3. While UT-2 flow technically meets the performance standard, 59 cumulative flow days is a bit
concerning from a habitat function perspective. It would be helpful to add context in the
narrative if influencing factors have been identified (e.g., drought category).
Noted. The MY5 report goes into more detail about the gauge on UT-2.

4. Figure 2 shows two random Veg Plots named #1
This has been corrected in MY5.
5. The areas around RVP1 and VP2 were supplementally planted with 3-gallon container trees in
March of 2022. Please provide the percentage of the site that underwent supplemental planting
in the MY5 report.
The percentage of the site that underwent supplemental planting in 2023 has been included in
the MY5 report. Supplemental planting that occurred in MY4 covered 2.6% of the project area.
6. A beaver dam was noted on reach HB-2 in January 2022 and beaver management occurred
during the winter of 2022.
The beaver dam was not noted during 2023 monitoring events.
7. Table 10. 2022 Rainfall Summary. Please provide all rainfall observations in previous year since
last MY report and not the year to date.
This year's Table 10 is now "MY5 Rainfall Summary" and includes the rainfall from September
2022 to August 2023.
RES is requesting a 10% (350.200 SMUs) credit release for Year 5 monitoring.

i.o Project Summary
1.1 Project Location and Description
The Dairyland Stream Mitigation Site (the "Site") is located within a watershed dominated by
agricultural and residential land use in Orange County, North Carolina, about eight miles
Southwest of Hillsborough. The project area exhibited diminished hydrology and habitat value as
a result of past and on -going agricultural activities. The project involved the restoration,
enhancement, and protection of streams in the Cape Fear River basin.
The project lies within the Haw River Basin and Jordan Lake Watershed (8-digit USGS HUC
03030002, 14-digit USGS 03030002050030). The project watershed is primarily characterized by
agriculture, forests, and low -intensity residential areas.
The total easement area is 28.6 acres. Adjacent fields are dominated by corn and soybeans.
Vegetation around the ponds and the unbuffered stream reaches (HB1, HB2, and UT2) was
primarily composed of herbaceous vegetation and scattered trees. The existing farm ponds
offered little habitat to support aquatic life, and the riparian buffers were not maximizing their
potential to filter nutrients.
The Site will be monitored on a regular basis and a physical inspection of the site will be conducted
at a minimum of twice per year throughout the seven-year post -construction monitoring period,
or until performance standards are met. These site inspections will identify site components and
features that require routine maintenance. The measure of stream restoration success will be
documented by bankfull flows and no change in stream channel classification. The measure of
vegetative success for the site will be the survival of at least 210 seven-year old planted trees per
acre at the end of year seven of the monitoring period.
Upon approval for closeout by the Interagency Review Team (IRT), the site will be transferred to
Unique Places to Save (UP2S), an approved third -party long-term steward. The long-term steward
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. Easements will be
stewarded in general accordance with the guidelines published by the National Land Trust
Alliance. These guidelines include annual monitoring visits to easements and related
communication with the landowner(s).
1.2 Project Goals and Objectives
The North Carolina Division of Mitigation Services (DMS) develops River Basin Restoration
Priorities (RBRP) to guide its restoration activities within each of the state's 54 hydrologic units.
The 2009 Cape River Basin RBRP identified several restoration needs for the entire Cape River
Basin, as well as for hydrologic unit code (HUC 03030002), specifically. To satisfy these needs RES
has established the RES Cape Fear 02 Umbrella Mitigation Bank, with the first approved bank site
being the Dairyland Mitigation Site.
Dairyland i Year 5 Monitoring Report
Stream Mitigation Site August 2023
The Site is located within the Haw River, the major river in HUC 03030002. This river and its
tributaries flow to B. Everett Jordan Lake, a drinking water supply. This supply has been designated
a Nutrient Sensitive Water and NC Division of Water Resources (DWR) has developed a set of
goals to reduce non -point source pollution in its watershed. Goals include promoting nutrient and
sediment reduction in agricultural and urban areas by restoring and preserving streams, wetlands,
and riparian buffers. The Site provides compensatory mitigation for impacts on the Waters of the
US under the Section 404 of the Clean Water Act.
Project goals will be addressed through the following project objectives:
• Dam breach and pond removal,
• Restoration of appropriate pattern, dimension, and profile in stream channels.
• Restoration of forested riparian stream buffers,
• Enhancement of hydrology and vegetation in existing riparian wetlands,
• Treatment and control of exotic invasive species,
• Stabilization of eroding stream banks due to lack of vegetation, and
• Addition of large woody debris, such as log vanes, log weirs, root wads.
Due to its location and improvements, the Site provides numerous ecological and water quality
benefits within the Cape Fear River Basin. While many of these benefits are limited to the project
area, others, such as pollutant removal and improved aquatic and terrestrial habitat, have farther -
reaching effects. Many of the project design goals and objectives, including restoration of riparian
buffers to filter runoff from agricultural operations, improvement of terrestrial habitat, and
construction of in -stream structures, address the degraded water quality and nutrient input
stressors identified as major watershed stressors in the 2009 Cape Fear RBRP.
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 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
Dairyland 2 Year 5 Monitoring Report
Stream Mitigation Site August 2023
cross -sections should fall within the quantitative parameters defined for channels of the design
stream type. Bank height ratio shall not exceed 1.2, and the entrenchment ratio shall be no less
than 1.4 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. Vegetation monitoring will occur
between July 1st and leaf drop and includes 11 permanent vegetation plots and four random
vegetation plots. 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, 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. 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.
1.4 Project Components
Mitigation credits presented in these tables are based upon site design in the approved final
mitigation plan. SMU totals were adjusted and calculated using the most recent non-standard
buffer width guidance. The stream mitigation components are summarized in Table 1, as well as
Figure 2.

*SMUs are adjusted in accordance with Section XI(C)- "Procedures to Calculate Credits for Non-
standard Buffer Widths", published in the October 2016 Wilmington District Stream and Wetland
Compensatory Mitigation Update. A detailed description of the methodology and calculations is
described in the Approved Mitigation Plan.
1.5 Design/Approach
The 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 "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
(Skidmore, et al., 2001). Hydraulic geometry was developed using analytical methods in an effort
to identify the design discharge.
Dairyland 4 Year 5 Monitoring Report
Stream Mitigation Site August 2023
Priority Level I Restoration was performed on Reaches HB-2 and UT-2, both of which were farm
ponds. Restoration activities included draining and breaching the existing impoundments and
constructing channels once the ponds had been breached. A combination of Priority I Restoration
and Enhancement Level 11 was performed along the primary project channel (Reaches HB-1 and
HB-2) to address existing impairments, particularly impoundment, floodplain disconnection, and
buffer degradation. Enhancement III was performed on Reaches UT-1 and WF-2, as the channel
is stable throughout, regularly accesses its floodplain and provides a variety of aquatic habitats.
Preservation was performed for Reach WF-1. The channel is stable throughout, regularly accesses
its floodplain and provides a variety of aquatic habitats.
1.6 Construction and As -Built Conditions
Stream construction was completed in August 2018 and planting was completed in November
2018. The Dairyland Mitigation Site was built to design plans and guidelines. Baseline channel
length and stationing is based on design centerline. The only notable change that was made
during construction was changing the crossing between HB-1 and HB-2 from a culvert to a ford.
This modification, which is outside of the conservation easement area, was made based on the
large amount of bedrock unearthed after the ponds were dewatered. The design engineer drafted
and sealed a bulletin drawing to retain the bedrock features and tie-in with the downstream
stream design as shown in the Mitigation Plan. Also, a few log structures were removed from the
design to utilize the existing bedrock found in the new channel location and retained the designed
channel slope. Following Hurricane Florence and Hurricane Michael, the stream construction
contractor added rip rap material around the grade control structures from 7+00 to 9+00 on UT-
2. During the As -Built Site Visit with the IRT on November 29, 2018, RES agreed that the amount
of rip rap material was not appropriate for the design. Shortly after the site visit, RES removed the
rip rap from the areas not directly around structures. Two other areas that were identified during
this site visit included two small encroachment areas along WF-2 and the general comment to
treat invasive species in the WF-2 easement area.
1. 7 Monitoring Performance (MY5)
The Monitoring Year 5 (MY5) activities were completed in June and August 2023. All monitoring
data is present below and in the appendices. The Site is on track to meet vegetation and stream
interim success criteria.
Vegetation
Monitoring of the 11 fixed vegetation plots and four random vegetation plots was completed
during August 2023. Vegetation data are in Appendix C, and associated photos and plot locations
are in Appendix B. MY5 monitoring data indicates that all plots but one are exceeding the interim
success criteria of 260 planted stems per acre. Planted stem densities ranged from 162 to 1,012
planted stems per acre with a mean of 585 planted stems per acre. A total of 16 species were
documented within the plots. The average tree height observed in the permanent vegetation plots
was 9.8 feet.
Dairyland 5 Year 5 Monitoring Report
Stream Mitigation Site August 2023
Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous
vegetation is becoming well established throughout the project. There are two bare areas totaling
0.02 acres in size and one low stem density area about 0.15 acres in size. One of the bare areas
(VPA-2) is down slope of the head -cut that was repaired in 2022. The repair has been blown out
(VPA-1), and will be fixed again this fall in addition to planting 3-gallon container species and
putting down a herbaceous seed mixture for added stability in the eroded area below. The second
bare area (VPA-3) is near fixed vegetation plot 5 and the low stem area (0.15 acres, VPA-4) is
around random veg plot 4. These areas will also be supplementally planted this dormant season
with 3-gallon container species, and the bare area will be seeded with the herbaceous mix.
The road that passes through the preservation area has been blocked off with planted 3-gallon
container trees in April 2023. The trash pile that was noted adjacent to the road was removed,
filled in, and seeded with an herbaceous mixture. 0.29 acres (1% of the project area) including and
surrounding the filled trash pile was planted with 3-gallon container trees at a density of 260
stems per area (VPA-9). The area will continue to be monitored in future years to ensure no
encroachment is occurring.
Chinese privet (Ligustrum sinense) was treated within the preservation area in April 2023. Larger
areas of privet near the Enhancement II reach will be treated this Fall (VPA-8), along with a small
grove of tree -of -heaven (Ailanthus altissima) (VPA-7). Additionally, two areas of moderately dense
loblolly pine (Pinus taeda) will be removed around the downstream extent of UT-2 and HB-2 (VPA
5 & 6).
Stream Geomorphology
Geomorphology data for MY5 was collected during June 2023. Summary tables and cross section
plots are in Appendix D. Overall, the cross sections relatively match baseline condition, or
demonstrate stable conditions since expected minor adjustments during the first few years after
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. One
area of bank erosion was observed around a log sill at Cross Section 7. This area has repaired itself
slightly since MY3 and is not considered a problem in MY5 due to the continued presence of thick
livestake growth in the area. RES will continue to closely monitor this structure.
Geomorphology data for MY5 is included in Appendix D. No areas of concern were noted during
the site walk and the stream is transporting sediment as designed.
Dairyland 6 Year 5 Monitoring Report
Stream Mitigation Site August 2023
Stream H, d�gy
There are two stage recorders on site, one on Reach HB-2 and one on Reach UT-2. Additionally,
as requested by the IRT, RES is reporting flow data on Reach UT-2. MY5 hydrology data shows
four bankfull events on HB-2 and 13 on UT-2. The highest event on HB-2 was 0.74 feet above
bankfull and the highest event on UT-2 was 0.97 feet above bankfull. Reach UT-2 reported 80
consecutive flow days and 84 cumulative flow days. It should be noted that gauge UT-2 is located
on a riffle, so dry readings do not mean the entire stream is dry. More accurately the riffle may be
dry but there is still water located in the nearby pools. The flow chart shows very few periods of
time where there was absolutely no recording on the gauge, meaning the stream likely had some
water in its pools for most of the year. Gauge locations are shown on Figure 2 and full hydrology
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 16 cross -sections. Survey data were imported
into CAD, ArcGIS®, and Microsoft Excel® for data processing and analysis. The stage recorders
include a flow gauge and a crest gauge. The flow gauges were installed within the channel and
will record flow conditions at an hourly interval. The crest gauges were installed on the bank at
the bankfull elevation. During quarterly visits to the Site, the height of the corkline will be
recorded. HOBO data from the flow gauges will be corrected using bankfull recordings from the
crest gauges. In result of crest gauge failure, the flow gauges will be corrected using the water
depth at the gauge and the height of the top of bank at the gauge. Additionally, flow data is
corrected using the height of the downstream riffle to detect flow.
Vegetation success is being monitored at 11 permanent monitoring plots and four random
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. The random
plots are to be collected in locations where there are no permanent vegetation plots. Random
plots will most likely be collected in the form of a 100 square meter belt transect. Tree species and
height will be recorded for each planted stem and the transects will be mapped and new locations
will be monitored in subsequent years.

General Note -The above component table is intended to be a close complement to the asset map.
Each entry in the above table should have clear distinction and appropriate symbology in the asset
map.
1- Wetland Groups represent pooled wetland polygons in the map with the same wetland type and
restoration level. If some of the wetland polygons within a group are in meaningfully different
landscape positions, soil types or have different community targets (as examples), then further
segmentation in the table may be warranted. Wetland features impacted by credit modifiers such as
utilities shall be listed as a distinct record with the impacted acreage tallied as discreet records in the
table (See Wetland 7 above)
2 - Wetland Position and Hydro Type - Indicates Riparian Riverine, (RR) , riparinan non-riverine (RNR)
or Non-Riverine (NR)
3- Buffer Assets - due to the complex nature of buffer and nutrient offset assets they are not
included in this example table. Please see the DMS buffer mitigation plan template for the required
asset table information.
4- Adjusted Mitigation Credits are based on the non-standard buffer widths.

I - 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 - rare).
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

Shaded cells indicate that these will typically not be filled in.
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 - rare).
3. Utilizing XS measurement data produce an estimate of the bankfull fioodplain area in acres, which should be the area from the top ofbank 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. Ofvalue/needed only if the n exceeds 3
