Dear Harry,
Equinox has completed the review of the Little Pine Creek II Draft MY01 Monitoring Report comments.
Following are the responses to those comments (in Red)
Report and tables
• Cover page contract#/ID info is not all correct(DWR project number). Please use the correct info
from the approved MYO/Baseline report cover. Updated
• References throughout of the stream to "LPCII Creek" should be changed to "LPC" or "Little Pine
Creek". If referencing the project name, it should be LPC II or Little Pine Creek II. Updated within
text, tables, and graphics.
• Please include the IRT's 4/3/2020 MYO approval email (attached) in the MY1 Appendices for
reference. Please also reference the approval email in the report text. Inserted in Appendix F and
Referenced in the document.
• Please include the responses to the IRT's 4/3/2020 MYO approval comments (attached) in the
MY1 Appendices for reference. Inserted in Appendix F and referenced in the document.
• Please correct the indentation inconsistencies in the project sections and subsections. Reviewed
and edited indentation structure.
• Appendices/tables etc— Except for CCPVs, if possible all pages should all be letter sized; 11x17
tables and figures should be formatted to fit the letter size report. Please tri-fold any 11x17 CCPV
foldout sheets in the final hard copies. Condensed tables and figures to letter size pages where
legibility can be maintained.
• Section 1.4 project components - Credits stated do not reflect approved MYO/Baseline report.
Please correct. Please also take out credits to the appropriate decimal places to match the asset

table. Please indicate that the project credits reflect those that were approved as part of the Little
Pine Creek II—Project As-Built Update and Mitigation Plan Addendum(downward adjustment)
and include that memo in an addendum (attached). Eliminate the reference to the as-built survey
as this was handled in the baseline report. Credits and number formatting updated in Table 1 and
text, Credit reference updated and added to Appendix F.
• Table 1 /Assets — Credits listed do not reflect approved MYO/Baseline report. Please correct.
Please also tabulate credits to the appropriate decimal places to match the asset table. Attached
is the current table format needed.This is basically the same as what you all used for the Fletcher
MYO/baseline, with some minor changes. Updated Table 1,
• Table 2 — Annual monitoring report delivery should not be a separate project event. The
monitoring report delivery date (month-year) should be reflective of each year's stream and
vegetation surveys. Updated table accordingly.
• Please indicate that a supplemental warranty-related planting will occur in January 2021 by the
construction contractor.The results of this planting event will be summarized in the MY02 report.
This need not be captured in the events table in this MY1 report, as it was not during calendar
year 2020. Inserted in Section 1.5.1
• Table 4—All project restoration reaches were listed in the PCN and permitted as perennial. Please
change the designation in this table of the tributary C listed as intermittent. Updated.
• Hydrology/ Verification of bankfull events (Table 12) — Crest gage and stage recorder data is
missing, in this table and the graphs. Please provide as contracted (2 crest gages on Tribs A and B,
and 2 stage recorders on LPC and Trib C), and list bankfull event verifications from these devices.
If there was a problem with the equipment it should be explained in the Project Performance
section.Text and graphics updated/added to report and supporting files.

Species information was not collected for RVP in MY1, but will be included in subsequent
monitoring events and displayed accordingly in future monitoring reports.
• Per IRT guidance, plot vegetation data collected must include:
1. Within each fixed plot: species, height, grid location, planted versus volunteer, and
age (based on the year the stem was planted, or first observed for volunteers)
2. Within each random plot: species and height
Due to a misunderstanding regarding the data collection parameters for random
vegetation plots (RVP), species and height information were not recorded during
MY1 RVP monitoring. Species and height parameters will be recorded during RVP
monitoring for the remainder of the monitoring years. The report text has been
updated accordingly.
3. For both fixed and random plots, all woody stems, including exotic and invasive
species, should be counted (exotic/invasive species will not count toward success of
performance standards).
• Please add all common names to CVS table; please only use one common name per species (see
MVO report). Table updated to include common names.
CCPVs
• If possible, please refine invasives polygons to better reflect field conditions; the larger areas
shown on the map are not reflective of the scattered invasive occurrences on the ground. Adjust
Table 6 accordingly. Current polygons were reflective of invasive presence on the ground in
addition to vines within the woodline. Report text and the CCPV updated to better describe the
density and composition of invasive vegetation.
• Failing vegetation plots should be colored orange or red and captured in the legend. Failing
vegetation plots are colored red.
• Reach break between LPC 2A and 2B should be shown on the CCPVs. Reach break inserted.
• Continuous stage recorders and crest gages are missing from the CCPVs and legend. Please add.
Continuous stage recorders and crest gauges added to CCPVs.
• Please change the color of the OHW to gray/neutral color so as not to conflict with the cross
sections. OHW line color changed to gray.

From MYO to MY1 the length of Reach 2A increased by 30 feet, but it is unclear why. Please explain, and
either provide an updated feature or fix the asset table. An incorrectly segmented line was submitted for
the draft report. An updated feature has been provided which matches the asset table.
Please include the temporary veg plot features as polygons rather than points. Temporary random
vegetation plots added as polygons.
• Please include features illustrating the undercut and habitat segments that were outlined in Table
5 in the CCPV and submit these features. Observations from LPC Reach 1 were reviewed and
deemed insignificant for mapping at this time. Table 5 updated and the text was expanded to
better describe the current conditions and concerns.
• DMS has 13 photo point features, but the photos submitted indicate that there are 14 photo
points. Please include a feature for photo point 14 and resubmit. Feature included for photo point
14.
• The report suggests that the 2 crest gauges and continuous stage recorders displayed in the MYO
CCPV are still on site, but they are not represented spatially in the MY1 CCPV, and the data for the
continuous stage recorders were not included in the report. Please either include these data, or
explain why these gauges were removed. Continuous stage recorder and crest gauge geospatial
and hydrologic data has been added to geodatabase and report.

1.0 PROJECT SUMMARY
1.1. Project Setting and Background
The Site is located in eastern Alleghany County, NC, approximately eight miles east of the Town of
Sparta, NC and approximately four miles south of the Virginia border. The Site is within the New River
Basin; 14-digit Hydrologic Unit Code (HUC) 05050001030030 and located in the Blue Ridge Belt of the
Blue Ridge Province (USGS, 1998), (Figure 1).
The Site is located within a TLW in the New River RBRP plan (NCDENR,2009), and is identified in the
Little River and Brush Creek LWP Project Atlas (NCDENR,2007). Numerous stressors were identified
including heavily grazed buffers, livestock access to streams,eroded stream banks, land-disturbing
activities on steep slopes,and storm water runoff. The LWP Project Atlas identified the Little Pine
Creek II Stream and Wetland Restoration Project(LPC1-04, LPC1-W10) as a stream and wetland
restoration opportunity with the potential to improve water quality, habitat, and hydrology within the
Brush Creek watershed.Tables 1-4 in Appendix A present the project details.
1.2. Goals and Objectives
The following goals are outlined in the Final Mitigation Plan, and include:
• Restore riparian buffers
• Exclude cattle
• Stabilize eroding banks
• Construct stream channels that are laterally and vertically stable
• Improve stream habitat
• Improve channel and floodplain connectivity
• Permanently protect the project site from harmful uses
The following project objectives are proposed for accomplishing the goals as outlined in the Final
Mitigation Plan:
• Plant native tree and understory species in the riparian zone.
• Install fencing along the conservation easement and cattle pasture boundaries
• Reconstruct stream channels with stable dimensions, add bank revetments and in-stream
structures to protect restored/enhanced streams.
• Construct stream channels that will maintain a stable pattern and profile considering the
hydrologic and sediment inputs to the system, landscape setting and the watershed
condition.
• Install habitat features such as constructed riffles and brush toed into restored/enhanced
streams,add woody materials to channel bed, and construct pools of varying depth.
• Reconstruct stream channels with bankfull at or near the floodplain elevation and bank
height ratios ranging from 1.0- 1.1.
• Establish a conservation easement on the site.
1.3. Restoration Type and Approach
The project includes six restoration reaches;three Priority 1(P1) reaches on Little Pine Creek,one
Priority 2(P2) reach on Tributary A,one P1 reach on Tributary B,and one P1 reach on Tributary C. The
preservation portion of the Site includes Tributaries D, E,and F.The wetland portion of the LPC II Site
Little Pine Creek II MY1 Monitoring Document
NC DMS Project No 856 1 Equinox
Monitoring Year 1 2020
includes three wetland zones.Wetland 1 is a riparian, non-riverine wetland enhancement zone.
Wetland 2A is a riparian, non-riverine wetland enhancement zone.Wetland 2B is preservation only.
1.4. Project Components and Success Criteria
The LPC II Site is expected to provide 3,195 SMUs and 1.484 WMUs.The components and mitigation
credits Project credits reflect those approved as part of the March 13,2020 Little Pine Creek II-Project
As-Built Update and Mitigation Plan Addendum (downward adjustment),Appendix F. Refer to the
Project Assets Map (Figure 2)for the stream and wetland features and Table 1 and 4 for the project
components, assets, and mitigation credit information for the LPC II Site (Appendix A).
The initial credit release for LPC II was received on April 3,2020. A copy of the Notice of Initial
Credit Release and the responses to the IRT Review of the Little Pine Creek II Initial Credit Release can
be found in Appendix F.
1.5. Project Performance
1.5.1 Vegetation
Visual assessment of vegetation indicates that the herbaceous vegetation is well established
throughout the project. MY1 annual mean for planted stems was 331 stems/acre and ranged from 121
to 607 planted stems per acre. Eight species were documented within the vegetation monitoring
plots.
Monitoring of both permanent(n=8) and random vegetation plots (n=6) was completed in
October 2020. Summary tables and photographs associated with MY1 vegetation monitoring are
located in Appendix B and Appendix C. MY1 monitoring data indicates that all but one permanent
vegetation plot was failing to meet the MY3 interim success criteria of 320 planted stems per acre
(Table 7 and 8,Appendix C.)
Vegetation problem areas appear to be restricted to the immediate floodplain of Little Pine Creek
where areas of scour and deposition have had the greatest impact on stem density. Some of the low
stem density areas noted in MY0 are still present, particularly those within the channel belt width on
Reach 2A(Table 6 and CCPC,Appendix B). A supplemental warranty-related planting is scheduled for
January 2021.
Areas of exotic vegetation are depicted within the CCPV. Multiflora rose (Rosa multiflora),Oriental
bittersweet(Celastrus orbiculatus) and Japanese honeysuckle (Lonicera japonica) were the dominant
observed species. Invasive vegetation was identified in low density throughout LPC Reach 2A. In the
most contiguous area of invasives noted within the CCPV, a more significant density of oriental
bittersweet was identified along the forested edge and within the canopy. While the size of the
polygon is significant,the overall density of invasive vegetation is low.The location and density of
invasive vegetation will continue to be monitored in future site visits.
1.5.2 Geomorphology
Visual assessment of the stream channel was performed to document signs of instability,such as
eroding banks,structural instability,or excessive sedimentation. Reaches 1 and 2 both experienced
some impacts due to a high flow events in April and May of 2020. The first area on LPC II Reach 1 is
located on the left descending bank of Cross-section 1. In this area,overbank flows have eroded a
portion of the left descending floodplain and is depicted within the cross-section and photos. The
Little Pine Creek II MY1 Monitoring Document
NC DMS Project No 856 2 Equinox
Monitoring Year 1 2020
second area in Reach 1 is located near STA 101+50. In this area a transverse riffle has formed and is
currently directing stream flow towards the left descending bank. This area is not currently
considered a problem area but will be monitored for any changes in stability. Two areas of concern
were noted on LPC II Reach 2. The first is located between Cross-sections 3 and 5. This area has
received a significant level of overbank deposition and debris wracking along the easement boundary.
The second area of concern is a line of scour located mid-reach at STA 112+00. This area is located
along the midline of the right descending bank floodplain and drains to a vernal pool. High flows and
increased velocity coming out of the straight portion of Little Pine Creek exiting the NCDOT bridge
right-of-way have scoured out this area for approximately 20 feet. These areas were not identified as
stream problem areas as they have stabilized over the course of MY1. Low stem density was identified
as the only residual effect, (Table 6 and CCPV,Appendix B). These areas will continue to be monitored
in future site visits for further signs of instability.
Geomorphic data for MY1 was collected during October 2020. Summary tables and cross-section
data plots related to stream morphology are located in Appendix D. Cross-sectional dimensions
remained relatively stable between baseline conditions and MY1 monitoring efforts. The most
substantial changes took place at cross-sections 1,2,3,and 4. Cross-section 1 had the bankfull width
increase by 7.3 feet and the width/depth ratio decreased by 10.1. Additionally, a significant change in
the flood-prone area was noted with both,scour and deposition visible in MY1. Cross-section 2, has
shown a significant change in dimension between MYO and MY1. Bankfull max depth decreased by 1.1
feet and significant over-bank deposits were observed. Cross-sections 3 and 4 had a less drastic
change in dimension,showing distinct over-bank deposits (Appendix D,Cross-Section overlays and
Table h a). Riffle dimensions for Reach 2 remained relatively similar between baseline conditions
and MY1 monitoring. Similarly to Reach 1, new overbank deposits are evident from the cross-
sectional surveys (Appendix D,Table 11b). No areas of instability were noted. The site will continue
to be monitored for signs of instability.
Additionally,the condition of the water-gate at the beginning of Reach 2A was documented and a
photo is included below. No areas of encroachment or fence failure were observed during the
assessment, although a significant amount of flood debris has accumulated on the fence line at the
start of LPC II Reach 2. The next site visit is planned for spring 2021.
1.5.3 Hydrology
Since project completion in late 2019, a minimum of five bankfull events have been documented
at the LPC II Site. Based on precipitation and stage recorder data the events were recorded over
6 days; January 12,January 24th, February 7,April 13,April 29,July 19, and May 21,2020 (Table 12,
Appendix E). Five events were recorded on Little Pine Creek, and three events were recorded at the
Tributary C, and one at Tributary B. No bankfull events were recorded on Trib A during MY1. Data
indicated that the May 21,2020 storm event buried the continuous stage recorder located on Little
Pine Creek. This recorder was subsequently recovered,downloaded, and reset during the MY1
geomorphology monitoring.
2.0 METHODS
2.1 Geomorphology
Geomorphic measurements were taken during low flow conditions using a Nikon NPR 332 Total
Station. Three-dimensional coordinates associated with cross-section data were collected in the field
Little Pine Creek II MY1 Monitoring Document
NC DMS Project No 856 3 Equinox
Monitoring Year 1 2020
and geo-referenced (NAD83 State Plane feet FIPS 3200). Morphological data were collected at 13
cross-sections. Survey data was imported into CAD,ArcGIS,and Microsoft Excel for data processing
and analysis. Channel substrate was characterized using a Wolman Pebble Count as outlined in
Harrelson et al(1994) and processed using Microsoft Excel.
2.2 Vegetation
Vegetation success in MY1 is being monitored at 8 permanent monitoring plots in conjunction
with random vegetation plots. Permanent 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 is processed using the CVS data entry tool. In the
field,the four corners of each permanent plot were permanently marked with metal t-posts and PVC
pipe. Photos of each plot were taken from the plot origin each monitoring year. In MY1, random
vegetation plot monitoring was conducted erroneously using the warranty vegetation plot protocol of
total planted stems per plot. In future monitoring years random vegetation plots will be monitored as
per Section V of the Wilmington District Stream and Wetland Compensatory Mitigation Update
(USACE 2016). Data is processed analogous to the CVS data entry tool. In the field,the four corners of
each plot were temporarily marked.
2.3 Hydrology
Two crest gages,two continuous stage recorders,two groundwater gages, and a rain gage were
utilized to monitor, meteorological,surface, and groundwater within the site. Additionally,visual
observations of bankfull event indicators will be documented throughout the project. Data will be
recorded and reported through subsequent monitoring reports.

Good afternoon,
The 15-Day Record Drawing review for the Little Pine II Stream and Wetland Mitigation Site(SAW-2009-00591)ended March 31,
2020.Per Section 332.8(o)(9)of the 2008 Mitigation Rule,this review followed the streamlined review process.All comments received
from the NCIRT are incorporated within this email.Please address the IRT concerns by replying to this email.There were no objections
to issuing the initial credit release,or approving the Mitigation Plan Addendum.Please find attached the current signed ledger.
DWR Comments:
1. The meeting minutes dated 11/14/2019,state that supplemental planting will be completed during the next dormant period.The
MY0 Report CVS Table shows that 5 of the 8 veg plots do not meet success criteria.Yet,the report does not mention plans for
supplemental planting.Please confirm.In addition to low stem counts,the veg plots show low species diversity.Only a total of 5 tree
species(including Red Maple and Green Ash)and 1 shrub species were identified in all of the veg plots.With an approved planting list
of 20 species,please confirm that the species and percent stems noted on As-Built Sheet 3.2 accurately reflect what has been planted.
DWR requests that a supplemental planting effort include a variety of the approved species.Due to concerns associated with Emerald
Ash Borer,DWR recommends that Green Ash not be included in a supplemental planting effort.
2. During the IRT site walk on 11/5/2019,several bare areas and areas of sparse herb cover were noted along Reach 2A,which may
not have been visible during the veg survey with 3-4 inches of snow cover.Please monitor closely during the MY1 to determine if soil
amendments and reseeding is warranted.
3. Also during the IRT site walk,there was discussion of relocating the Wetland 2A groundwater gauge and potentially modifying the
Wetland 2A target community type.Neither points were mentioned in the MY0 Report,please provide a brief explanation why not.
Please let me know if you have question.
Thanks,
Kim

DATE: March 13, 2020
DMS requests an amendment to the Little Pine Creek II Restoration Project Mitigation Plan assets to
become consistent with the as-built alignment adjustments, recent stream preservation credit
deductions, and overhead utility presence not previously accounted for. The following tables
summarize the changes requested. This will result in a net change of-107.6 SMUs. Wetland credits
remain unchanged. In summary:
• 40.6 SMU reduction due to preservation Tributaries E and F (203 LF total)becoming
ineligible for credit as agreed on at 11/5/2019 Site meeting with IRT (see Project Meeting
Minutes dated 11/14/2019);this was due to recent downcutting and partial deterioration of
channel conditions since original design;
• 50 SMU deduction (all restoration reaches)due to 2 overhead wire (OHW)rights-of-way not
accounted for in the IRT-approved Little Pine Creek II Restoration Project Restoration Plan
Addendum, January 15, 2016;
• 17 SMU(all restoration reaches) deduction due to as-built alignment adjustments (see
following table comments for detail).
