Executive Summary
Wildlands Engineering was contracted by the North Carolina Division of Mitigation Services (DMS)
to provide stream and wetland credits in the Catawba River Basin HUC 03050101. Restoration and
preservation of Site streams was approved to provide 4,836.307 stream credits within the final
approved mitigation plan dated March 2022. Approved mitigation plan crediting included a credit loss of
‐256.640 for lack of buffers and a credit gain of 361.480 for additional buffers, resulting in a net change
in credits of +104.840. All crediting adjustments were developed using the Non‐Standard Buffer Width
Calculation tool provided by the Wilmington District USACE included within the approved mitigation
plan Appendix 12.
Based on site conditions during construction, slight adjustments to UT1 Reach 2 and UT2 bankfull
alignments were made to preserve trees and/or conform the proposed streams to the existing valleys.
Additionally, detail and attention were paid to areas of limited buffer, and top of bank locations were
adjusted slightly to ensure the full required 30‐feet. The typical sections were still maintained within
these areas and overall design intent was maintained. All areas of deviation from design are shown in
the included Mitigation Site Record Drawings and outlined in the baseline monitoring report.
Wildlands completed grading and earthwork construction in October 2022 and a‐built surveys were
completed in January 2023. The survey included developing an as‐built topographic surface; as well as
surveying the as‐built channel centerlines and top of banks. Upon receipt of the as‐built data, surveyed
stream top of bank locations were used to determine credit employing the Non‐Standard Buffer Width
Calculation tool provided by the Wilmington District USACE. Identical versions of the tool were used for
the approved mitigation plan and as‐built/baseline reports. Results from the tool indicated that small
changes made during construction reduced credit loss to ‐234.350 while increasing credit gain to
367.080. The as‐built net change in credits totaled +132.730. Baseline crediting approved within the
mitigation plan was held consistent within the buffer tool calculation. Total as‐built crediting at the Site
was determined as 4,864.197, which is 27.890 credits beyond the approved mitigation plan crediting. To
acquire these additional assets, Wildlands has included this mitigation plan addendum, including a
revised Section 11.0 – Determination of credits and a revised Table 21 – Project Asset Table. Revised
crediting, including the Buffer Calculation Summary sheet and associated Figure are included in
Appendix F.
11.0 Determination of Credits
1.1 Determination of Credits Overview
Mitigation credits presented in Table 21 are projections based upon the proposed design.
The credit ratios proposed for the Site have been developed in consultation with the NCIRT as
summarized in the included meeting minutes (Appendix 6 of the approved Mitigation Plan).
1. The requested stream restoration credit ratio is 1:1 for mitigation activities that include
reconstruction of the channels to a stable form and connection of the channels to the adjacent
floodplain. This level of effort will occur on East Prong Hunting Creek Reach 1 and Reach 2, UT1
Reach 2, and UT2.
2. UT1 Reach 1 is proposed for preservation credit at a 15:1 ratio. Proposed work along this reach
includes establishing the conservation easement and invasive species removal.
The credit release schedule is provided in Appendix 11 of the approved Mitigation Plan.
1.2 Credit Calculations for Non‐Standard Buffer Widths
To calculate functional uplift credit adjustments, the latest published version of the Wilmington District
Stream Buffer Credit Calculator from the USACE was utilized. To perform this calculation, GIS analysis
was performed to determine the area (in square feet) of ideal buffer zones and actual buffer zones
around the Project stream. Minimum standard buffer widths are measured from the top of bank (30
feet in the mountain county of Burke). The ideal buffers are the maximum potential size (in square feet)
of each buffer zone measured around all creditable stream reaches, calculated using GIS, including areas
outside of the easement. The actual buffer is the square feet in each buffer zone, as measured by GIS,
excluding non‐forested areas, all other credit type (e.g., wetland, nutrient offset, buffer), easement
exceptions, open water, areas failing to meet the vegetation performance standard, etc. The stream
lengths, mitigation type, ideal buffer, and actual buffer are all entered into the calculator. This data is
processed, and the resulting credit amounts are totaled for the whole project. Based on the credit
analysis, the Buffer Credit Calculator computed a net gain of +132.730 credits; therefore, the total
adjusted SMUs for the Project is 4,864.197. Revised Appendix 12 contains details of the Non‐Standard
Buffer width calculation including the credit calculator spreadsheet result and buffer credit calculation
figure.

Buffer Width Zone (feet from Ordinary High Water Mark)
7Square feet in each buffer zone, as measured by GIS, excluding non‐forested areas, all other credit type (e.g., wetland, nutrient offset, buffer), easement exceptions, open water, areas failing to meet the vegetation performance standard, etc. Additional credit is given to 150 feet in buffer width, so areas within the easement that are more
than 150 feet from creditable streams should not be included in this measurement. Non‐creditable stream reaches within the easement should be removed prior to calculating this area wtih GIS.
6Maximum potential size (in square feet) of each buffer zone measured around all creditable stream reaches, calculated using GIS, including areas outside of the easement. The inner zone (0‐15') should be measured from the top of the OHWM or the edge of the average stream width if OHWM is not known. Non‐creditable stream reaches
within the easement should be removed prior to calculating this area wtih GIS.
3Use the Custom Ratio fields to enter non‐standard ratios, which are equal to the number of feet in the feet‐to‐credit mitigation ratio (e.g., for a perservation ratio of 8 feet to 1 credit, the multiplier would be 8).
2Minimum standard buffer width measured from the top of bank (50 feet in piedmont and coastal plain counties or 30 feet in mountain counties)
4Equal to the number of feet of stream in each Mitigation Type. If stream reaches are not creditable, they should be excluded from this measurement, even if they fall within the easement.

Dear Kristi,
Baseline Report and Drawings
The NC Division of Mitigation Services (DMS) has reviewed the Draft Baseline (MY0) Report and As Built
Drawings for the Laurel Valley Site. Following are DMS’s comments on this deliverable:
Please include the Mitigation Plan Addendum request in the Mitigation Plan, either as an Appendix or
before the main body of the report (up front).
Table 1 (Project Quantities and Credits) – Add existing LF and Priority Levels columns; please omit any
unneeded colors. It would be preferable if you could just use the MP addendum version of this table
here; the additional buffer credits gain/ loss, and net result all need to be in this table as your MP
addendum table shows.
Table 2 (Goals, Performance Criteria, and Functional Improvements) – Please add re-verification of
wetlands at MY7 per IRT review letter dated 10/27/2021 (K. Browning comment).
Table 2 (Goals, Performance Criteria, and Functional Improvements) and CCPV – Please add a gauge or
trail camera in Mitigation Plan Wetland F (left bank UT1 around 218+00-220+00) per IRT review letter
dated 10/27/2021 (E. Davis comment), to demonstrate a sustained hydrological connection.
Section 2.1 (bulleted changes below) –
• STA: 217+57 – STA: 217+92 – Alignment altered to save adjacent mature trees. Length of
alignment deviation is 33.36 linear feet (LF).
• STA: 308+60 – STA: 309+12 – Alignment adjusted to preserve existing trees. Length of alignment
deviation is 45.40 LF.
• STA: 310+48 – STA: 310+88 – Alignment altered to protect existing mature trees. Length of
alignment deviation is 37.05 LF.
These are the 3 segments where alignment changed; in addition to the lengths of ‘alignment deviations’,
please list the net change in lengths realized by these changes, for each segment.
Section 2.1.7 Fencing Plan – Since recent land use removing cattle from project pasture areas has
dictated changes in the fencing needs (i.e., removal) for the project, can Wildlands briefly discuss what
land use changes are expected in the near term (hay, agriculture, etc.) and how Wildlands plans to
adjust their monitoring approach to ensuring the integrity of the easement? Assuming these fields will
be mowed or maintained in some way, without fencing, there is a legitimate risk of scalloping. Does
Wildlands plan to add any signage or non-livestock boundary fencing in these areas? If mowing or other
encroachments occur, how does Wildlands plan to remedy this? Please discuss in this section and clarify.
Photo Points – Please make sure during the monitoring period that photos of the culverts from both
sides are shown (PP3, PP4, and PP13), to show potential perching (typically at the outlet) and/or debris
jamming (typically at the inlet).
Vegetation Plot Data Tables – Can a lighter shade of green perhaps be used; the dark green does not
allow very good visibility of the text (either hard copy or PDF).
Mitigation Plan Addendum
• It is not entirely clear where the additional credits (+44.390) are originating; Wildlands mentions
the three minor realignments, and resurveying channel center lines and tops of banks, but it is
not clear precisely where on the project the additional credits come from. Please provide more
details or clarification.
• Please note that despite the additional credits being sought, Wildlands is not pursuing a contract
amendment with DMS.
• Credit Table / Project Credit Adjustments – Total Adjusted SMUs should be 4,880.697, not
4,880.690.
MY0 Boundary Inspection
The MY0 DMS boundary inspection was conducted on March 14, 2023. The inspection was conducted in
accordance with the DMS Property Checklist which included an office review and a site visit to
document site conditions. The entire easement boundary was inspected during the site visit to validate
easement integrity and identify any potential issues on the site. The report letter is attached to this
email and summarizes those inspection results. Site photos and locations are shown on the attached
kmz map.
Please respond to me regarding the action items in the letter; if more time is needed to address
anything please indicate a plan and timeline for resolution.
Digital Support Files
• Please remove the parking access symbols, or rename to “temporary parking location”, or similar
as these are unplatted areas outside the conservation easement. Access or long term permission
should not be implied.
• Please verify that the construction of the As-built fence located within the utility ROW and fencing
located outside of easement has been approved by landowner.
• Please re-submit x-section features, each cross section must have a unique identifier There are
currently 3 x-section 1’s included in the submission.
• The project streams as submitted do not currently reflect the proposed assets; resubmit these
features to reflect the project segment and linear feet as characterized in the quantities and
credits table.
Please submit two final hard copies, in addition to a flash drive or CD with a PDF of the report and all
digital support files (addressing any comments) in the correct file structure. Please include a copy of your
response letter, inserted inside the front cover of each hard copy report (and included in the final PDF).

Harry,
The MY0 DMS boundary inspection was conducted on March 14, 2023. The inspection was conducted in
accordance with the DMS Property Checklist which included an office review and a site visit to document site
conditions. The entire easement boundary was inspected during the site visit to validate easement integrity and
identify any potential issues on the site. This report summarizes those inspection results. Site photos and locations
are shown on the attached kmz map.
Office Review:
• An approved utility corridor (non credit generating) is located in the northwest corner of the site. The overhead
wires are shown outside CE on the plat and As-built.
Field Inspection:
• The rebar at corner #2 was topped with a plastic surveyor cap and missing the stamped aluminum monument
cap.
• Corners 3, 4 & 5 were missing marker posts.
• In-line marker spacing met specification, but the adjacent fields are in hay production and lack an established
mow line.
• A fallen tree has damaged the fence near corner #30.
• Adjacent ditch construction is in-progress upgradient of corner #32.
• No encroachments were observed.
Action Items
• Install aluminum monument cap at corner #2.
• Install corner marker posts at corners #3, 4 & 5.
• The mow line is not well established along the adjacent fields. Coordinate with landowner and install any
supplemental marking necessary to prevent scallop mowing.
• Repair fence damaged by the fallen tree near corner #30.
• Coordinate with the landowner to ensure no encroachment occurs due to the active ditch construction near corner
#32.

Dear Mr. Harry Tsomides,
Wildlands Engineering, Inc. (Wildlands) has reviewed Division of Mitigation Services’ (DMS)
comments from the Draft Monitoring Year 0 (MY0) Report for the Laurel Valley Mitigation Site.
The report has been updated to reflect those comments. Wildlands’ responses to DMSs’
comments are noted below.
DMS Comments, Harry Tsomides:
Baseline Report and Drawings:
1. Please include the Mitigation Plan Addendum request in the Mitigation Plan, either as an
Appendix or before the main body of the report (up front).
Wildlands Response: The Mitigation Plan Addendum is now included before the main
body of the report.
2. Table 1 (Project Quantities and Credits) – Add existing LF and Priority Levels columns; please
omit any unneeded colors. It would be preferable if you could just use the MP addendum
version of this table here; the additional buffer credits gain/ loss, and net result all need to
be in this table as your MP addendum table shows.
Wildlands Response: Table 1 has been updated to reflect the MP addendum version.
3. Table 2 (Goals, Performance Criteria, and Functional Improvements) – Please add re‐
verification of wetlands at MY7 per IRT review letter dated 10/27/2021 (K. Browning
comment).
Wildlands Response: Wetland re‐verification in MY7 has been added to Table 2 of the
report.
4. Table 2 (Goals, Performance Criteria, and Functional Improvements) and CCPV – Please add
a gauge or trail camera in Mitigation Plan Wetland F (left bank UT1 around 218+00‐220+00)
per IRT review letter dated 10/27/2021 (E. Davis comment), to demonstrate a sustained
hydrological connection.
Wildlands Response: Table 2 has been revised to include the installation of a trail
camera in Wetland F, near photo point 10 (PP10), during MY1 to show a sustained
hydrologic connection throughout the monitoring years. The location of the camera will
be recorded with GPS and added to the CCPV map in the MY1 report.
5. Section 2.1 (bulleted changes below) –
STA: 217+57 – STA: 217+92 – Alignment altered to save adjacent mature trees.
Length of alignment deviation is 33.36 linear feet (LF).
STA: 308+60 – STA: 309+12 – Alignment adjusted to preserve existing trees. Length
of alignment deviation is 45.40 LF.
STA: 310+48 – STA: 310+88 – Alignment altered to protect existing mature trees.
Length of alignment deviation is 37.05 LF.
There are the 3 segments where alignment changed; in addition to the lengths of ‘alignment
deviations’, please list the net change in lengths realized by these changes, for each segment.
Wildlands Response: The bulleted changes above in Section 2.1 were updated to
include the loss of LF for each alignment deviation. However, it should be noted that
lengths recorded for UT1 Reach 2 and UT2 in the Site’s original Mitigation Plan were
recorded incorrectly. The Mitigation Plan’s lengths were recorded as 14 LF shorter than
they should have been for each reach. This is why the as‐built lengths are recorded as
longer than the Mitigation Plan even though there were linear footage losses on the
reaches due to alignment deviations. Text describing this inconsistency was included in
Section 2 of the Monitoring Year 0 Annual Report (2023).
6. Section 2.1.7 Fencing Plan – Since recent land use removing cattle from project pasture
areas has dictated changes in the fencing needs (i.e., removal) for the project, can Wildlands
briefly discuss what land use changes are expected in the near term (hay, agriculture, etc.)
and how Wildlands plans to adjust their monitoring approach to ensuring the integrity of the
easement? Assuming these fields will be mowed or maintained in some way, without
fencing, there is a legitimate risk of scalloping. Does Wildlands plan to add any signage or
non‐livestock boundary fencing in these areas? If mowing or other encroachments occur,
how does Wildlands plan to remedy this? Please discuss in this section and clarify.
Wildlands Response: Language was added to Section 2.1.7 to address the change in
agricultural land use at the Site, potential encroachments, and potential remediation as
necessary.
7. Photo Points – Please make sure during the monitoring period that photos of the culverts
from both sides are shown (PP3, PP4, and PP13), to show potential perching (typically at the
outlet) and/or debris jamming (typically at the inlet).
Wildlands Response: PP3 and PP4 are the inlet and outlet, respectively, of the same
culvert. In MY1, a photo point will be added at the inlet of the culvert of PP13. A
representative photo will be taken at this new photo point in future monitoring reports
MY1 – MY7.
8. Vegetation Plot Data Tables – Can a lighter shade of green perhaps be used; the dark green
does not allow very good visibility of the text (either hard copy or PDF).
Wildlands Response: The colors on the Vegetation Plot Tables are consistent with the
Shiny App output. In past monitoring reports, Wildlands has been advised to leave
colors as is produced by the Shiny App.
Mitigation Plan Addendum:
1. It is not entirely clear where the additional credits (+44.390) are originating; Wildlands
mentions the three minor realignments, and resurveying channel center lines and tops of
banks, but it is not clear precisely where on the project the additional credits come from.
Please provide more details or clarification.
Wildlands Response: To simplify additional crediting, Wildlands defaulted baseline
crediting to the approved mitigation plan values. The additional crediting proposed
within the addendum (+27.890) is the result of reducing the areas under the minimum
buffer during project development and construction which reduced the overall negative
crediting calculated within the Wilmington District Stream Buffer Credit Calculator from
USACE. Differences in proposed and as‐built bankfull locations are shown in the record
drawings (Appendix E).
2. Please note that despite the additional credits being sought, Wildlands is not pursuing a
contract amendment with DMS.
Wildlands Response: Wildlands is not pursuing a contract amendment with DMS.
3. Credit Table / Project Credit Adjustments – Total Adjusted SMUs should be 4,880.697, not
4,880.690.
Wildlands Response: Table 1 was updated with revised crediting.
MY0 Boundary Inspection:
The MY0 DMS boundary inspection was conducted on March 14, 2023. The inspection was
conducted in accordance with the DMS Property Checklist which included an office review and a
site visit to document site conditions. The entire easement boundary was inspected during the
site visit to validate easement integrity and identify any potential issues on the site. The report
letter is attached to this email and summarizes those inspection results. Site photos and
locations are shown on the attached kmz map.
1. Please respond to me regarding the action items in the letter; if more time is needed to
address anything please indicate a plan and timeline for resolution.
Wildlands Response: Wildlands has included our responses to the action items in the
boundary inspection report after our Digital Support File responses below.
Digital Support Files:
1. Please remove the parking access symbols, or rename to “temporary parking location”, or
similar as these are unplatted areas outside the conservation easement. Access or long‐term
permission should not be implied.
Wildlands Response: The parking access symbols have been removed from CCPV maps.
2. Please verify that the construction of the As‐built fence located within the utility ROW and
fencing located outside of easement has been approved by landowner.
Wildlands Response: As‐built fence located within the utility ROW and outside the
conservation easement was approved by the landowner. When the property was sold,
Wildlands met and negotiated new closed loop sections of fence based on the new
property owner’s agricultural needs.
3. Please re‐submit x‐section features, each cross section must have a unique identifier. There
are currently 3 x‐section 1’s included in the submission.
Wildlands Response: On Thursday May 25, 2023, Kristi Suggs (Wildlands) contacted
Melonie Allen (DMS) to inquire about this comment. It seems that somehow two of the
cross‐sections in the digital file that DMS’ GIS program was reading were missing a
second digit in the cross‐sections’ name. The correct name for the cross‐sections were
XS10 and XS11. During this conversation, Ms. Allen was able to correct the cross‐section
name in the file that DMS’ had; therefore, no additional rectification is needed.
4. The project streams as submitted do not currently reflect the proposed assets; resubmit
these features to reflect the project segment and linear feet as characterized in the
quantities and credits table.
Wildlands Response: The project’s stream features have been updated to reflect the
project segment, asset type, and linear footage that are characterized in the quantities
and credits table.
DMS Comments, Kelly Phillips:
Conservation Easement Inspection Report Action Items:
1. Install aluminum monument cap at corner #2.
Wildlands Response: Corner #2 is a common property corner with DB 740, Pg1512, BD
1891, PG719 (Tract 1) and DB1509, PG133. This property corner was either missing or
damaged during boundary survey. The surveyor reset the property corner with a rebar
and cap as described in the legend on the recorded plat and Exhibit A of the
Conservation Easement Area A. This corner would not have an aluminum State of NC
conservation easement cap as all existing property corners will not have conservation
easement caps.
2. Install corner marker posts at corners #3, 4 & 5.
Wildlands Response: Marking post signage has been set at corners 3, 4, and 5. Photos of
the marker signage are included below.
Boundary Marker #3 Boundary Marker #4 Boundary Marker #5
3. The mow line is not well established along the adjacent fields. Coordinate with landowner
and install any supplemental marking necessary to prevent scallop mowing.
Wildlands Response: Wildlands will work with the landowner to establish a mowing line
to prevent encroachment. If needed, Wildlands will install additional posts, tape, and/or
signage to prevent scallop mowing.
4. Repair fence damaged by the fallen tree near corner #30.
Wildlands Response: The fallen tree has been cleared from the fence. See the photo
below. A fencing repair is scheduled to be completed by August 1. No livestock or
animals are contained within the area where the fence is currently damaged. Wildlands
will provide photos in the MY1 report of the completed fence repair.
5. Coordinate with the landowner to ensure no encroachment occurs due to the active ditch
construction near corner #32.
Wildlands Response: Wildlands spoke with the landowner. A French drain is being
installed along the driveway and stops outside the conservation easement. The small,
excavated ditch will be filled and revegetated as part of the French drain installation.
Wildlands will provide photos in the MY1 report of the completed French drain.
As requested, Wildlands has included two (2) hard copies, a .pdf copy of the final report, and a
full final electronic submittal of the support files. A copy of the MY0 DMS boundary inspection
report, the DMS comment letter for the draft Baseline (MY0) Report and Record Drawings, and
our response letter have been included inside the front cover of each report’s hard copy, as
well. Please let me know if you have any questions.

Section 1: PROJECT OVERVIEW
The Laurel Valley Mitigation Site (Site) is in Burke County, approximately 3.5 miles southeast of
Morganton. The Site is within the NC Division of Mitigation Services (DMS) Hunting Creek targeted local
watershed Hydrologic Unit Code (HUC) 03050101060050 and the NC Division of Water Resources (DWR)
Subbasin 03‐08‐31. The Site will provide stream mitigation units (SMUs) in the Catawba River Basin HUC
03050101 (Catawba 01). Table 3 presents information related to the project attributes.
1.1 Project Quantities and Credits
Mitigation work within the Site included the restoration and preservation of approximately 5,175 linear
feet (LF) of perennial stream channel and enhanced and preserved up to an additional 120 LF of riparian
buffer in areas across the Site. As outlined in the Laurel Valley Mitigation Plan Addendum (Wildlands,
2023), this will generate 4,864.197 SMUs for the Catawba 01. Table 1 below shows stream credits by
reach and the total amount of stream credits expected at closeout.

1.3 Project Attributes
The project Site is bordered by an active farm comprised of cattle pastures, barns, and a residence.
Based on historic aerials from 1947 to 2016, East Prong Hunting Creek and UT2 have existed in their
same approximate location and with the same pattern for over 72 years. Aerials show that UT1
historically flowed into East Prong Hunting Creek within the project Site and was rerouted sometime
between 1976 and 1984. Agricultural management of open pastures remained consistent between 1947
and 2016, with a brief period between 1976 and 1984 when pastures were fallow. Table 3 below and
Tables 8a – 8b in Appendix C present additional information on pre‐restoration conditions.

Section 2: As‐Built Condition (Baseline)
The Site construction was completed in October 2022, and as‐built surveys were completed in January
2023. The survey included developing an as‐built topographic surface; as well as surveying the as‐built
channel centerlines, top of banks, structures, and monitoring components. Monitoring device
installation and vegetative data collection were completed in January 2023. However, the post‐
construction planting at the Site was completed in March 2023.
Slight adjustments during the construction of UT1 Reach 2 and UT2 resulted in a loss of 1.640 LF and
9.550 LF on the reaches, respectively. However, the as‐built lengths for UT1 Reach 2 and UT2 are longer
than the proposed lengths in the project’s original Mitigation Plan (Wildlands, 2022). This is due to a
Laurel Valley Mitigation Site
Monitoring Year 0 Annual Report ‐ FINAL 2‐7
discrepancy in the lengths recorded for UT1 Reach 2 and UT2 in the Project Asset Table (Table 21) in the
Mitigation Plan (2022). The lengths were recorded as follows:
UT1 Reach 2 was recorded as 1,975 LF, but it should have been 1,989 LF, which is a difference of
14 LF.
UT2 was recorded as 1,542 LF, but it should have been 1,556 LF, which is also a difference of 14
LF.
Therefore, the total length that was recorded as part of the Mitigation Plan (Wildlands, 2022) was 28 LF
shorter than what was proposed in the design plans, so the loss of 11.190 LF from the alignment
deviations still yields a net length of 16.810 LF at as‐built.
2.1 As‐Built/Record Drawings
A sealed half‐size set of the record drawing and as‐built survey are in Appendix E which includes the
post‐construction survey, alignments, structures, and monitoring features. Field adjustments made
during construction that differ from the design plans are shown as red lines on the record drawing.
These adjustments were made during construction, where needed, based on field evaluations, and are
listed below.

STA: 312+07 – Cover log replaced brush toe for undercut bank pool habitat.
2.1.6 Vegetation Planting List & Plan
As‐built changes in species planted and densities were minimal when compared to design. Species
replacements and planting density adjustments were made due to availability of the species at the time
of planting. All species replacements were approved species or alternate species within the Final
Mitigation Plan’s planting list (Wildlands, 2022), so no approval for the inclusion of the species is
needed.
Open Buffer Planting Zone
Trees
Boxelder (Acer negundo) and cucumber tree (Magnolia acuminata) were not planted.
Sycamore (Platanus occidentalis) density increased from 15% to 16%.
River birch (Betula nigra), red mulberry (Morus rubra), and sourwood (Oxydendrum arboreum)
density increased from 5% to 6%.
American beech (Fagus grandifolia), bitternut hickory (Carya cordiformis), white oak (Quercus
alba), northern red oak (Quercus rubra), and slippery elm (Ulmus rubra) density increased from
10% to 11%.
Small Trees / Shrubs
Sweetshrub (Calycanthus floridus) was added at a density of 1%.
Wetland Planting Zone
Trees
Boxelder was not planted.
Small Trees/Shrubs
Silky dogwood (Cornus amomum) was added at a density of 5%.
Riparian Corridor Planting Zone
No deviations from design.
Partially Vegetated Buffer Zone
No deviations from design.
Laurel Valley Mitigation Site
Monitoring Year 0 Annual Report ‐ FINAL 3‐9
Planting Plan
No deviations from design.
2.1.7 Fencing Plan
As‐built changes to the proposed fencing plan that was provided in the Site’s Mitigation Plan (Wildlands,
2022) were redesigned during construction based on a change in land use specifications from the new
landowner when the property was sold. Cattle are no longer on‐site, and the new landowner’s horses
are restricted from accessing the conservation easement by fencing installed during construction and
existing fencing. In the locations where cattle were removed, fields will be used for hay. A mow line will
be established with the property owner to prevent encroachment. Additional marking or non‐livestock
fence will be considered if there is repeated encroachment. See Sheet 3.0 in the record drawings for the
fence location.
2.1.8 Monitoring Components
Installed monitoring devices and plot locations closely mimic the locations of those proposed in the
Site’s Mitigation Plan. Minor deviations from these locations were made when professional judgement
deemed them necessary to better represent as‐built field conditions or when installation of the device in
the proposed location was not physically feasible.
Section 3: Monitoring Year 0 Data Assessment
Annual monitoring and site visits were conducted during MY0 to assess the condition of the project. The
vegetation and stream success criteria for the Site follow the approved success criteria presented in the
Mitigation Plan (Wildlands, 2022). Performance criteria for vegetation, stream, and hydrologic
assessment are located in Section 1.2 Table 2: Goals, Performance Criteria, and Functional
Improvements. The first annual monitoring assessment (MY1) will be completed in the fall/winter of
2023, at least 6 months after the MY0 assessment. The Site will be monitored for a total of seven years,
with the final monitoring activities scheduled for 2029.
3.1 Vegetative Assessment
The MY0 vegetative survey was completed in January 2023. Vegetation monitoring resulted in a stem
density range from 526 to 729 planted stems per acre which is well above the interim requirement of
320 stems per acre required at MY3. Average stem density was 644 planted stems per acre. All 10
permanent and 2 mobile vegetation plots met the MY3 interim success criteria and are on track to meet
MY7 success criteria of 210 stems per acre. Herbaceous vegetation is establishing itself across the site.
Refer to Appendix A for Vegetation Plot Photographs and the Vegetation Condition Assessment Table
and Appendix B for Vegetation Plot Data.
3.2 Vegetation Areas of Concern
Vegetation management including herbicide applications were implemented prior and during
construction to prevent the spread of invasive species that could compete with planted native species.
In August 2022, approximately 50 linear feet of UT2 was chemically treated in‐stream for a small
population of marsh dewflower (Murdannia keisak), and fescue (Festuca sp.) was chemically treated
during construction in areas outside the limits of disturbance.
Preservation areas along UT1 Reach 1 were assessed for invasive species populations prior to
construction and at baseline conditions. No substantial populations, mature species, or seed sources
were observed; therefore, no treatment was conducted. Throughout the seven‐year monitoring period,
Wildlands will continue to monitor for the presence of invasive species populations within the
Laurel Valley Mitigation Site
Monitoring Year 0 Annual Report ‐ FINAL 3‐10
preservation area of UT1 Reach 1 and treat as needed. Invasive species will continue to be monitored,
mapped, and controlled across the Site as necessary throughout the monitoring period.
3.3 Encroachment
As discussed, and approved in the Site’s Mitigation Plan (Wildlands, 2022), a utility easement, along the
northwest side of the property, lies within the conservation easement. No stream nor buffer credit is
being sought for any part of the project that lies within the utility easement. The utility easement
supersedes the conservation easement and allows for utility and vegetation maintenance. Since this
easement overlap was approved, moving forward it will not be considered as an easement
encroachment violation; therefore, no easement violations were noted during the as‐built review of the
Site.
3.4 Stream Assessment
Morphological surveys for MY0 were conducted in November 2022. All streams within the Site are
stable and functioning as designed. All 11 cross‐sections at the Site show little to no change from design
in the bankfull area and width‐to‐depth ratio, and bank height ratios are less than 1.2. Refer to Appendix
A for the Visual Stream Morphology Stability Assessment Table and Stream Photographs. Refer to
Appendix C for Stream Geomorphology Data.
3.5 Stream Areas of Concern
Inspection of stream structures and banks did not identify any stream areas of concern, indicating that
the stream is performing as designed. The Site will continue to be monitored and any issues will be
mapped and reported throughout the monitoring period.
3.6 Hydrology Assessment
Crest gages (CG) were installed on East Prong Hunting Creek, UT1, and UT2 to monitor bankfull events.
An off‐site automated transducer (CG4) was also installed on an adjacent parcel to monitor baseflow
hydrology and large flow events of an off‐site hydrologic resource. No performance criteria are
associated with CG4; however, the on‐site gages (CG1 – CG3) are required to meet the performance
standards outlined in Table 2. Hydrologic data will be collected and reported during MY1.
3.7 Adaptive Management Plan
Site maintenance and adaptive measurement implementation will follow those outlined in the project’s
Final Mitigation Plan (Wildlands, 2022). No adaptive management implementation is needed at this
time.
3.8 Monitoring Year 0 Summary
Overall, the Site is performing as intended and is on track to meet success criteria. All vegetation plots
are exceeding the MY3 interim requirement of 320 planted stems per acre, and all streams within the
Site are stable and meeting project goals. Herbaceous vegetation is establishing itself across the site. In‐
stream vegetation and fescue were treated prior to and during construction and the presence of
invasive species is minimal. All vegetative species of concern will continue to be assessed and treated, as
needed, throughout the seven‐year post‐construction monitoring period.
Summary information and data related to the performance of various projects and monitoring elements
can be found in the tables and figures in the report appendices. All raw data supporting the tables and
figures are included in the digital submittal.

Monitoring Year 0 Annual Report ‐ FINAL 4‐1
Section 4: METHODOLOGY
Annual monitoring will consist of collecting morphologic, vegetative, and hydrologic data to assess
project success based on the goals outlined in the Site’s Mitigation Plan (Wildlands, 2022). Monitoring
requirements will follow guidelines outlined in the NC IRT Stream and Wetland Mitigation Guidance
Update (2016). Installed monitoring devices and plot locations closely mimic the locations of those
proposed in the Site’s Mitigation Plan. Deviations from these locations were made when professional
judgement deemed them necessary to better represent as‐built field conditions or when installation of
the device in the proposed location was not physically feasible.
Geomorphic data was collected following the standards outlined in The Stream Channel Reference Site:
An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in Stream Restoration: A Natural
Channel Design Handbook (Doll et al., 2003). All Integrated Current Condition Mapping was collected by
either a professional licensed surveyor or an Arrow 100® Submeter GNSS Receiver and processed using
ArcPro. Crest gages, using automated pressure transducers, were installed in riffle cross‐sections to
monitor stream hydrology throughout the year. Stream hydrology and vegetation monitoring protocols
followed the Wilmington District Stream and Wetland Compensatory Mitigation Update (NCIRT, 2016).
Vegetation installation data collection follow the Carolina Vegetation Survey‐EEP Level 2 Protocol (Lee et
al., 2008); however, vegetation data processing follows the NC DMS Vegetation Data Entry Tool and
Vegetation Plot Data Table (NCDMS, 2020).
