Mr. Wiesner,
As per your letter concerning the Owen Farms Stream and Wetland Mitigation Site MY3 Report, we have
updated the report and addressed your comments as follows:
Response to DMS Comments
1: General: Please review the DMS notes and confirm that all requests, IRT questions and full delivery
provider commitments from the 2023 credit release meeting have been addressed and included in the
final MY3 (2023) report. DMS/IRT questions have been reviewed and addressed.
2: Section 1.2 – Background: “Additionally, 1.396 acres of wetlands have been enhanced,…”. Please
update the report text to 1.540 acres per the IRT approved mitigation plan and Table 1. Acreage in Section
1.2 has been updated accordingly.
3: Section 2.2.2 Vegetation & Section 3.0 Maintenance and Adaptive Management Plans: Section 2.2.2
reports replanting in February 2023 & Section 3.0 reports replanting in January 2023. Please review and
update the discrepancy in the report. Discrepancy in Section 2.2.2 has been updated accordingly. The site
was replanted in February 2022, following repair activities in January 2022. A small amount of replanting
was also completed in January 2023 following repair activities in November 2022. Table 5 has also been
updated to help add clarity.
4: Section 2.2.2 Vegetation: Is existing Fescue considered a project vegetation concern within the
conservation easement? Are any ring sprays around planted vegetation proposed in future monitoring
years? Please address in the comment responses and update the report text accordingly. Although fescue
is present in the easement it is not jeopardizing survivability of planted or native vegetation. Ring sprays
around planted vegetation are not necessary and not planned at this time.
5: Table 5. Project Activity and Reporting History: Morphological surveys and vegetation surveys were
completed at separate times/ dates in MY3(2023); please update the table to identify the separate survey
dates. Based on the report text, morphological surveys were completed in March 2023. Please consider
collecting morphological data later in the growing season so it represents the full monitoring year. If
collected earlier, data collection dates should be consistent each year to allow a full year between surveys.
Please include all MY3(2023) maintenance activities in the table including beaver dam removal and project
invasive treatments. Activities and corresponding dates have been updated in Table 5. We prefer to collect
morphological data prior to leaf-out. Morphological surveys will be completed again in March 2025 during
MY5 to maintain consistency.
6: Table 8. Visual Vegetation Assessment: The table reports 0% encroachment; however, minor livestock
encroachment was identified and observed during a December 6, 2023, DMS site visit. Please review the
table and update the report accordingly. Table 8 updated to reflect livestock encroachment within
easement area.
7: Figure 7.4: Please update the “Daily Rainfall Totals” line in the graph legend. It currently reads “Series1”.
Graph legend title has been updated.
8: Table 13: A bankfull event is reported for MY3(2023) on 12/15/2022. Please explain why this is not
considered a MY2(2022) bankfull event. Please update the report accordingly. Table updated to accurately
portray bankfull event as occurring in MY2. Section 2.2.3 was also updated to reflect this change.
9: Table 14. Wetland Hydrology Summary: In the Performance Standard line of the table, please report
that the success criteria is 12% of the growing season and list the growing season dates from the IRT
approved mitigation plan. Comments have been updated accordingly in the summary table.
10: Figures 8.1 – 8.6 Groundwater gauge data graphs: Please review and confirm that the data reported
is accurate and the graph callouts are correct. As an example, the Gauge 1 (Figure 8.1) callout shows
occurrences of the groundwater line well below the “12 inches below surface” line. Please also be
consistent with the graph colors utilized. Figure 8.6 has a green “Wetlands 5, Gauge 5 line”. Please review
and update the report and graphs accordingly. Graph data has been reviewed and updated for accuracy
and callouts have been updated accordingly.
11: December 6, 2023: Property Boundary Inspection Observations& Required Action Items:
• The easement corners were adequately monumented with stamped aluminum caps. The caps were
typically flush with the ground surface making them easy to locate.
• Three witness posts were missing/damaged. The U-channel post at platted corner 72 at the top of UT7
has been damaged by highway maintenance. The post at platted corner 31 on the west side of wetland 1
could not be located. The fencepost used to witness platted corner 35 at the southwest corner of the
UT2A crossing corridor is located too far from the actual corner monument.
• Several signs were absent, missing nails, rotated, bent or otherwise damaged. The signs were fastened
to the wooden fence posts with galvanized roofing nails. Many of the damaged signs were on posts where
the nails had backed out of the post. The locations of damaged or missing signs are shown on the .kmz
provided to Davey.
• Signs were incorrectly attached to trees with roofing nails driven flush to the tree.
• In-line marking was not visible in portions of the wooded areas.
• Signs were installed outside the easement along the fence line between platted corners 1 and 30
(between the top of UT1 and Wetland 1).
• A yearling steer was observed inside the easement near platted corner 85. Cattle access to this area has
created a visible trail along the fence between corners 83 and 86. No exit gate could be found during the
inspection, so the cow remained inside the easement. Notification of the occurrence was provided by
DMS at the time of the inspection.
• There are multiple locations where relic fencing is located within the conservation easement. The
fencing consists of multi-strand barbed wire or woven wire attached to wooden posts, T-posts and trees.
The wire has been removed from some of the fence segments leaving only the metal T-posts as remnants.
• Two sections of silt fence are located within the easement on the east side of the site along Highway
281.
• A metal 55-gallon drum is located in the French Broad in the southeast section of the site.
•Based on a review with Davey staff (Ben Furr) it was unclear if livestock currently have access to portions
or all of UT1 due to uninstalled and/ or damaged fencing.
12: Required Action Items in MY4 (2024):
• Repair/install witness posts at the three locations identified.
• Repair/install all damaged or missing signs. DMS has consistently observed that roofing nails do not
perform well as fasteners for attaching signs to wooden posts and recommends using screw type fasteners
such as 2 ½ inch hex head sheet metal roofing screws rated for exterior treated lumber applications for
the repair.
• DMS recommends replacement of all tree sign fasteners with 16d aluminum nails such as the 3 ½ inch
by 0.177 inch by 11/32-inch head aluminum nails from Kaiser Aluminum 800-633-3156. Please watch the
DMS instructional video before correcting the signage https://youtu.be/7dE7edd3V5M . It is a five-minute
video originally created during the NC Ecosystem Enhancement Program era and helps visualize the
preferred method for attaching signs to trees.
• In-line marking was not visible along many of the wooded boundary sections and visibility of the
boundary needs to be improved. Due to the thick nature of the wooded areas, DMS recommends installing
signs on prominent boundary trees visible from a distance and blazing the trees with yellow survey paint.
A few signs should be made visible from Highway 281 and all other wooded areas where the signs are
absent/not visible.
• Remove signs installed outside the easement along the fence line between platted corners 1 and 30
(between the top of UT1 and Wetland 1).
• Notify the landowner that cattle are accessing the easement. Identify all locations where cattle are
gaining access and encroaching into the easement and repair the exclusion fencing. Remove any fallen
trees or limbs from the fence and repair any damage.
• Remove internal fencing wire and associated metal T-posts.
• Remove silt fence sections along Highway 281.
• Remove the metal 55-gallon drum located in the French Broad and properly dispose.
• Review documents and walk all of UT1 to determine if livestock potentially have access to the
conservation easement. Determine livestock access and add or repair fencing (as necessary) to exclude
livestock from the project’s conservation easement. Additional signage may be warranted if additional
fencing is installed.
DRG notes the aforementioned observation comments and will complete the following maintenance
actions requested by DMS.
If you have any questions or need additional information, please do not hesitate to give me a call
(919.588.9663).
Sincerely,
Davey Resource Group, Inc.

1.0 Project Summary
1.1 Location and Setting
The Owen Farms Mitigation Site (Site) is located approximately 3 miles north of Lake Toxaway in
Transylvania County, NC.
Directions from Asheville, NC:
From Asheville, NC: Travel on I-26 east to exit 40 (NC-280 W/Airport Road) and merge on to NC-280 W,
continue for 15.9 miles; continue straight onto US-64 W (NC-280 W becomes US-64 W), go 3.9 miles; turn
right to stay on US-64 W; continue on US-64 W for 14.9 miles; turn right on Blue Ridge Road, continue for
5.4 miles and the Site entrance will be on the left.
The Site is located in the Blue Ridge Belt Physiographic Province of North Carolina.
1.2 Background
In October 2020 HDR|ICA restored approximately 3,180 linear feet of stream, enhanced approximately
5,172 linear feet of stream (125 linear feet of Enhancement I; 5,047 linear feet of Enhancement II), and
preserved 423 linear feet of stream at the Owen Farms Mitigation Site. Additionally, 1.540 acres of
wetlands have been enhanced, 0.35 acres of wetlands have been re-established, and 0.97 acres of
wetlands have been rehabilitated at the Site. The Site provides many ecological functional uplifts within
the French Broad River Basin. Project goals were established based on the French Broad RBRP (NCEEP
2009), and on-Site data collected during the existing conditions survey. Site specific goals and objectives
were developed to provide the highest practical potential for functional uplift based on NC SAM and NC
WAM analyses of streams and wetlands on Site.
1.3 Preconstruction Conditions
Streams
The Site was cleared prior to 1951 and has been utilized for agricultural purposes including pasture and
row crops. Prior to construction cattle had access to the majority of streams on Site. The streams on Site
exhibited the following conditions prior to construction:
•Portions of WFFBR had been straightened to maximize agricultural practices on the property. The
channel exhibited actively eroding banks due to cattle hoof shear and many of the channel’s riffles
and pools had experienced significant deposition of fine material from the eroded channel banks.
The large majority of the channel displayed little to no deeply rooted bank or riparian vegetation.
Where a woody buffer had been present, it was commonly only one tree wide, with vegetation
typically sparse at best. Many of the trees within the one-tree buffer had been undercut because
the channel had incised below the rooting depth.
•UT 5 was dammed and ponded immediately downstream of a culvert passing under Silverstein
Road. Downstream of the pond, UT 5 had been straightened and channelized to its confluence
with the West Fork French Broad River (WFFBR).
•With the exception of the upstream most 248 feet, UT 7 had an absent to minimal buffer. The
downstream half of UT 7 appeared to have been modified for agricultural practices and ditched
along the edge of the valley as evidenced by an incised channel and spoil piles adjacent to the
banks.
Owen Farms Mitigation Site | DMS Project No. 100064
MY3 Monitoring Report
Transylvania County, NC Page 2 February 16, 2024
•UT 8 was fairly stable except for the downstream most 40 feet of the reach which experienced
down cutting to match the invert elevation of WFFBR at the confluence. In the downstream
portion of the reach there was little to no deeply rooted vegetation along the banks. The banks
had been lined with old bricks by the landowner in an attempt to prevent further mass wasting
as the channel continues to incise and undercut the banks.
•UT 4a was significantly incised due to a headcut approximately 20 feet upstream of its confluence
with UT 4.
•UT 1, UT 2, UT 2a, UT 3, UT 2b, UT 4, UT 4b, UT 6, UT 6a, UT 7a, and UT 7b are all first or second
order, spring fed, perennial tributaries which exhibited mild to moderate instability due to cattle
hoof shear and limited buffer presence in some areas before construction and planting activities.
Wetlands
Prior to construction cattle had access to all of the wetlands on Site. The wetlands on Site exhibited the
following conditions prior to construction:
•Wetland W3 is the largest wetland within the Site (1.8 acres) and is divided into two distinct
wetland types: Riverine Swamp Forest and Floodplain Pool. The Riverine Swamp Forest portion of
W3 had a significantly altered vegetative community compared to reference condition. This
portion of W3 consisted solely of herbaceous vegetation which was dominated by common rush
and served as a cattle pasture. Fecal matter and cattle tracks were present throughout the
wetland. The Floodplain Pool portion of W3 formed in a relic meander scroll of WFFBR. UT 5
flowed through the eastern portion of the Floodplain Pool prior to its confluence with WFFBR.
Cattle had unrestricted access to the entirety of W3.
•Wetland W5 was a relic Headwater Forest wetland area adjacent to UT 7. Prior to construction
the channelization and placement of spoil along the floodplain made it so W5 no longer supported
wetland hydrology. Cattle access also altered the vegetative structure and ground surface
condition.
•Wetland W1 is a Riverine Swamp Forest that is heavily influenced by beaver. Prior to construction
activities, cattle had full access to W1.
•Wetlands W2, W4, W6, W6A, W7, W8, and W9 are all headwater wetlands that had experienced
alterations to the vegetative structure and significant fecal matter inputs due to cattle access.
2.0 Annual Monitoring
2.1 Monitoring
Table 3 in Appendix A outlines all the monitoring components, methods, quantity, and frequency of data
to be collected for the Site. A visual representation of all monitoring devices can be found in the MY3
Current Conditions Plan View (CCPV) (Figures 2.1 – 2.9). Monitoring and data collection occurred between
March 30 and November 13, 2023.
2.2 Results and Discussion
This section documents the conditions observed in Year 3 monitoring. Areas that were repaired in
February and November of 2022 were assessed in 2023 for stability. Areas of minor to severe bank and
toe erosion that occurred after repairs in February 2022 were repaired in November 2022. Photographs
of select repaired areas can be found in Figures 3.31 – 3.50 and Appendix F.

MY3 Monitoring Report
Transylvania County, NC Page 3 February 16, 2024
2.2.1 Stream Stability
Cross section geometry along WFFBR has remained consistent with the As-Built condition. Repaired areas
have remained stable over the course of MY3 monitoring period. Visual observation of stream banks
indicates that WFFBR has stabilized after repairs in November 2022. Herbaceous and woody stream bank
vegetation has significantly increased during the MY3 monitoring period. Evidence of stream stability can
be seen in Figures 4.1-4.14 and Figures 5.1-5.14.
UT 8 cross sections remain largely unchanged over the past monitoring year. Cross section surveys show
changes in channel geomorphology between MY0 and MY1. However, geomorph surveys indicate that
the channel has found equilibrium between MY1 and MY3 and has remained stable over the past two
monitoring periods. A tree was discovered across the channel near cross section 7 in August 2023. The
tree is not impeding channel flow nor impacting bank stability.
Cross sections along UT 7 remain largely unchanged over the last monitoring year. The restored reach
appears stable and functioning as intended. It is worth noting that three small beaver dams were
discovered at STA 12+10, STA 12+85 and STA 13+45 on UT 7. Beaver dams were removed in August 2023.
Visual observations do not indicate instability of stream banks due to the presence of the beaver dams.
While the banks of UT 5 remain stable, the beaver dam that was discovered and removed at station 18+25
during MY2 monitoring period was rebuilt after geomorph surveys in March 2023. The beaver dam was
removed in August 2023 after trapping events in July 2023. Beaver dams had not been rebuilt on UT 5 or
UT 7 as of last site visit on December 5, 2023. Cross section surveys show changes in channel
geomorphology between MY0 and MY1. However, geomorph surveys indicate that the channel has found
equilibrium and has remained stable over the past three monitoring periods with no aggradation or
degradation being observed. The table below summarizes previous repairs for clarity.

MY3 Monitoring Report
Transylvania County, NC Page 4 February 16, 2024
2.2.2 Vegetation
Year 3 vegetation plot data can be found in Table 9 of Appendix C. The average density of planted stems
across the site is 486 stems per acre, which exceeds Year 3 success criteria of 320 planted stems per acre.
Plot 12 continues to fail to meet Year 3 criteria due to a dense herbaceous vegetative layer outcompeting
the planted bare roots. It is worth noting that Plot 12 is located in the Swamp Bog Complex planting area,
and it is not uncommon for this community to be dominated by shrubby and herbaceous species. Plot 12
exhibited 100 percent herbaceous coverage dominated by species such as common rush (Juncus effusus),
various sedges (Carex spp.), knotweed (Polygonum spp.), wool grass (Scirpus cyperinus), ironweed
(Vernonia fasciculata), and golden rod (Solidago sp.). It was anticipated in the Mitigation Plan that this
community may exhibit a lower stem density than the rest of the Site. Plot 12 will be visually assessed
during Year 4 monitoring to determine if any volunteer stems have established after an additional year of
growth. Vegetation plot 11, one of the three random plots on Site, was located in the Swamp Bog
Complex. It also failed to meet Year 3 criteria at 243 stems per acre and was comprised of 67% hazel alder.
The herbaceous community in Plot 11 was similar to what was observed in Plot 12. Findings between plot
11 and 12 confirm expectations noted in the Mitigation Plan about the Swamp Bog vegetative community.
It is also worth noting that visual stem densities in the swamp bog complex are low. This is not presented
in the Current Conditions Plan View figures or in the Visual Vegetation Condition table as it was anticipated
in the Mitigation Plan and discussed in prior monitoring reports.
Volunteers stems of hazel alder in Plot 3 continue to dominate the plot, comprising 53% of species
diversity in Plot 3, mostly in the areas affected by beaver dam flooding in MY2. Four new volunteer stems
were observed in Plot 3 during the MY3 vegetation survey. Provided that the beaver dam on UT2 is not
rebuilt in between MY3 and MY4, DRG anticipates stem composition to diversify over the subsequent
monitoring periods.
While Plot 10 is exceeding Year 3 success criteria in stem density, the mortality experienced by the plot
as a result of dense herbaceous growth resulted in the plot being comprised of 60% white oak (Quercus
alba). DRG anticipates volunteer stems to establish in the subsequent monitoring years, increasing species
diversity within the plot.
Plot 16, the second random plot on Site, was located within the wetland expansion area of W3. Results
from the MY3 survey indicate that this area has a stem density of 486 stems per acre. DRG observed 4
different species within the plot.
As a result of the repairs made to the floodplain along the left and right bank of West Fork French Broad
River in January 2022, DRG replanted approximately 733 bareroot stems within the repaired and disturbed
areas in February 2022. Vegetation plot 19, the third random vegetation plot on-site, was located within
the replanted area along the right floodplain of WFFBR. Results of the MY3 survey indicate that this area
has a stem density of 526 stems per acre.
Approximately 0.49 acres of the WFFBR floodplain have sparse herbaceous vegetation and are
represented as Areas of Vegetative Concern in Figures 2.1-2.9 in Appendix B. The majority of bare areas
observed are confined to areas that were disturbed during repairs made in January 2022. As a result of
poor soil quality in the disturbed areas herbaceous growth has been slow to establish. Woody vegetation
in these areas is a growing season behind the rest of the Site since it was replanted in February 2022.

Transylvania County, NC Page 5 February 16, 2024
Chinese privet (Ligustrum sinense) and Multiflora rose (Rosa multiflora) were observed within the
easement boundary along the floodplain of West Fork French Broad, UT1, UT2, UT4, UT5, UT7, and W3.
Multiflora rose was treated using Roundup Custom© in March and August 2023. Small areas of cattail
were observed within the channel of UT5 and was treated with Roundup Custom© in August 2023. Invasive
species will be monitored and treated as needed throughout the remainder of the monitoring period.
2.2.3 Stream Hydrology
All monitored streams have experienced continuous flow within tributaries and has been documented for
at least 30 consecutive days. To date, stream flow gauge data indicates that the site did not experience a
bankfull event during Year 3; however, UT8 recorded a bankfull event December 15, 2022, which was not
reported in the MY2 report. Hydrologic data for UT7 indicates a spike in water depth around June 14, 2023
that show water levels to at or above bankfull: this is indicative of the time when beaver dams were
constructed and is a false representation of a bankfull event. Stream hydrologic data between November
10, 2022 and November 23, 2023 can be seen in Figures 7.1 - 7.4 (Appendix E).
2.2.4 Wetland Hydrology
Wetland W3 re-establishment are exceeding success criteria, experiencing groundwater levels within 12
inches of the soil surface for at least 23% of the growing season, or 47 consecutive days over the Year 3
monitoring period (Figures 8.1-8.3, Appendix E).
Gauge data indicate that ground water within the wetland rehabilitation area has remained within 12
inches of the soil surface for 49% of the growing season, or 102 consecutive days over the Year 3
monitoring period (Figure 8.4, Appendix E) in the wetland expansion areas depicted on the CCPV Figures
in Appendix B.
The new gauge that was installed provide hydrologic data for areas extending beyond the delineated
boundaries of W3 has exceeded success criteria for Year 3, experiencing groundwater levels within 12
inches of the surface for 49% of the growing season, or 101 consecutive days.
Gauge 4, located within the enhancement area of W5, shows water levels within 12 inches of the soil
surface for 41% of the growing season, or 85 consecutive days during the Year 3 monitoring period (Figure
8.5, Appendix E). Data from Gauge 5, located in the re-establishment area of W5, shows groundwater
levels within 12 inches of the soil surface for approximately 32% of the growing season, or 65 consecutive
days over the Year 3 monitoring period (Figure 8.6, Appendix E).
Hydrographs presented in Figures 8.1-8.6 represent gauge data collected between November 13, 2022
and November 13, 2023.
3.0 Maintenance and Adaptive Management Plans
Areas that were repaired in November 2022 were replanted in January 2023. All repaired areas showed
increased amounts of herbaceous and woody vegetation during the Year 3 monitoring period. DRG does
not anticipate the need for any repairs on WFFBR in Year 4.
A section of downed fence was discovered along the right bank of UT4 due to a fallen tree in March 2023.
DRG removed the tree and repaired the fence at the time of discovery. Photos of the repaired fence can

MY3 Monitoring Report
Transylvania County, NC Page 6 February 16, 2024
be found in Appendix C, Figures 3.36-3.37. Calves were observed within the easement due to downed or
damaged fencing and/or kissing gates. DRG addressed this issue with the property owner and repaired
fencing. DRG also nailed wooden boards across the kissing gate entry points to prevent future cattle access
through kissing gates.
Chinese privet and multiflora rose were treated on the Site during the Year 3 monitoring period. Invasive
species on the Site will be monitored and treated as needed throughout the monitoring period.

Table 2. Project Goals, Performance Criteria, and Functional Improvements
Goal Treatment Functional Uplift Performance Criteria Measurements Monitoring Results
Restore/enhance
streams within the
Site so that they are
neither aggrading nor
degrading
Restore a stable dimension,
pattern, and profile. Install
fencing to exclude cattle.
Reduction of nutrients
and sediment to
downstream locations,
reduction of shear
stress, and improved
hydraulic function.
Entrenchment Ratios should be
≥ 2.2.
BHR should not exceed 1.2. BHR
should not change more than
10% in any given monitoring
interval.
Riffle section W/D ratios should
remain within the range of the
appropriate stream type.
Cross-section
monitoring and
visual inspections.
Stream dimensions have remained
stable throughout the site over the
past year. All cross sections BHR≤1.
Provide/ enhance
flood attenuation.
Restore several existing
streams as primarily a Priority
I restoration where bankfull
and larger flows can access
the floodplain. Construct
floodplain bench on WFFBR.
Increase attenuation
of floodwaters,
increase
biogeochemical
cycling and recharge
riparian wetlands.
Four bankfull events in separate
monitoring years.
Flow gauges
(Pressure
transducers), and
visual inspection.
During the 2023 MY, only UT 8
experienced a bankfull event.
Restore/enhance
aquatic, semi-
aquatic, and riparian
habitat.
Restore native vegetation to
the stream channel banks,
wetlands, and the adjacent
riparian corridor.
Treatment of nutrient
enriched surface
runoff from adjacent
pastureland, increased
bank stability and
increased habitat.
Minimum of 320 stems/ac
present at MY-3. Minimum of
260 stems/ac present at MY-5.
Minimum of 210 stems/ac
present at MY-7. Trees should
average 6 feet in height at MY-5
and 8 feet in height at MY-7.
Bog Complex communities may
exhibit lower stem density and
height.
Vegetation plots
will be monitored
annually between
July 1st and leaf fall
using the CVS
protocol.
Plots 11 and 12 fail to meet density
requirements. Plots 3, 10, and 20 fail to
meet diversity requirements.
Restore/Enhance
Wetlands within the
Site to remove
hydrologic
impairments
Reconstruct above bankfull
stream channel flows to
riparian wetlands and re-
grade topography to remove
spoil and overburden
material.
Restoration of riparian
habitat, treatment of
nutrient enriched
runoff from adjacent
pastureland, increased
flood attenuation.
Groundwater elevation within
12 inches of the ground surface
for at
least 12% of the growing season
(April 7 - October 30).
Groundwater
monitoring gauges.
All wetlands are meeting performance
criteria
Restore and connect
riparian habitat with
adjacent natural
communities.
Conservation easement
establishment.
Protect Site from
encroachment in
conservation
easement.
Prevent Easement
Encroachment. Visual inspection.
Damaged fencing resulted in short
term cattle access to areas within the
easement. Fencing has been repaired
and cattle removed from easement
area

Invasives may occur outside of planted areas and within the easement and will therefore be calculated 
against the total easement acreage . Include species with the potential to directly outcompete native,

Easement Encroachment Areas
Encroachment may be point, line, or polygon. Encroachment to be mapped consists of any violation of
restrictions specified in the conservation easement. Common encroachments are mowing, cattle access,
vehicular access. Encroachment has no threshold value as will need to be addressed regardless of impact
area.

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 
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:
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 (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.  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 
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

Virtual IRT meeting was held at 11:30am on Tuesday, April 18, 2023 to discuss the MY2 report and
approve MY2 credit release. The following represents highlights of discussions that occurred during the
meeting:
1.IRT requested that HDR include a stability analysis table and photos detailing the current
condition of each repair area by station in the MY3 report.
2.IRT stated that HDR would need to add an additional random/mobile vegetation plot to monitor
vegetation within the wetland expansion areas if we wanted to request credit for those areas in
the future. IRT also suggested documenting soil data (i.e. collecting soil profiles) in the
monitoring plots of wetland expansion areas.
3.IRT requested that HDR include a statement in the MY3 report explaining why Table 3
(Monitoring Plan Components) shows 5 site gauges and 2 reference gauges, but Table 14
(Wetland Hydrology Summary) only shows one reference. DRG explained that Gauges 2 and 3 in
W3 serve as reference gauges for the restored portion of W3 (for groundwater). They also serve
to monitor surface water within the W3 rehabilitation area.
4.IRT requested that HDR include a note on Table 14, in MY3 report, stating that Gauge 5 was
moved in 2022 to a more representative area within W5.
5.IRT suggested removing the ~ symbol from the hydrograph figures in MY3 report.
6.IRT requested that HDR provide a statement in the MY3 report about calves having access inside
the easement and how HDR addressed the issue (i.e. installed permanent barriers on kissing
gates and repaired fencing).
7.IRT noted that Figure 2.2 of the CCPV was not accurate (it is a duplicate of Figure 2.3), and
requested that HDR correct for MY3 report.
8.IRT agreed to a full credit release for MY2.
