1 Project Summary
pl�
Water and Land Solutions, LLC (WLS) completed the construction and planting of the Edwards -Johnson
Mitigation Project (Project) full -delivery project for the North Carolina Department of Environmental
Quality (NCDEQ), Division of Mitigation Services (DMS) in March 2018. The Project is located in Johnston
County, North Carolina between the Community of Archer Lodge and the Town of Wendell at 35' 43'
30.36" North and 78° 21' 22.90" West. The Project site is located in the NCDEQ Sub -basin 03-04-06, in
the Lower Buffalo Creek Priority Sub -watershed 030202011504 study area for the Neuse 01 Regional
Watershed Plan (RWP), and in the Targeted Local Watershed 03020201180050, all of the Neuse River
Basin.
The Project involved the restoration, preservation and permanent protection of four stream reaches (111,
R2, R3, and R4) and their riparian buffers, totaling approximately 3,729 linear feet of existing streams.
The Project construction and planting were completed in May 2018 and MY1 monitoring activities
occurred between May and November 2018 (Table 2). This report documents the completion of and
presents the data for the first year of monitoring (MY1). The Project meets the MY1 success criteria for
stream hydrology, stream horizontal and vertical stability, streambed material condition and stability, and
vegetation. Based on these results, the Project is expected to meet the Year 2 Monitoring success criteria
in 2019.
2 Project Background
2.1 Project Location, Setting, and Existing Conditions
The Edwards -Johnson Mitigation Project (Project) site is located in the Lower Buffalo Creek Priority Sub -
watershed 030202011504 study area for the Neuse 01 Regional Watershed Plan (RWP), in the Wake -
Johnston Collaborative Local Watershed Plan, and in the Targeted Local Watershed 03020201180050, all
of the Neuse River Basin. The Project site is situated in the lower piedmont where potential for future
development associated with the 1-540 corridor and rapidly growing Johnston County area is imminent,
as described in the Regional Watershed Plan (RWP) for the Upper Neuse River Basin within Hydrologic
Unit (HU) 03020201.
The RWP identified and prioritized potential mitigation strategies to offset aquatic resource impacts from
development and provided mitigation project implementation recommendations to improve ecological
uplift within the Neuse 01 Sub -basin, which included traditional stream and wetland mitigation, buffer
restoration, nutrient offsets, non-traditional mitigation projects such as stormwater and agricultural
BMPs, and rare, threatened, or endangered (RTE) species habitat preservation or enhancement.
The project included four stream reaches (R1, R2, R3, and R4) which involved the restoration, preservation
and permanent protection of approximately3,729 linear feet of streams permanently protected by a
conservation easement. The catchment area is 223 acres and has an impervious cover less than one
percent. The dominant land uses are agriculture and mixed forest. Prior to Project construction, some of
the riparian buffers were less than 50 feet wide.
2.2 Mitigation Project Goals and Objectives
WLS established project mitigation goals and objectives based on the resource condition and functional
capacity of the watershed to improve and protect diverse aquatic resources comparable to stable

pl�
headwater stream systems within the Piedmont Physiographic Province. The proposed mitigation types
and design approaches described in the final approved mitigation plan considered the general restoration
and resource protection goals and strategies outlined in the 2010 Neuse River Basin Restoration Priority
Plan (RBRP). The functional goals and objectives were further defined in the 2013 Wake -Johnston
Collaborative Local Watershed Plan (LWP) and 2015 Neuse 01 Regional Watershed Plan (RWP) and
include:
• Reducing sediment and nutrient inputs to the upper Buffalo Creek Watershed,
• Restoring, preserving and protecting wetlands, streams, riparian buffers and aquatic habitat,
• Implementing agricultural BMPs and stream restoration in rural catchments together as "project
clusters".
The following site specific goals were developed to address the primary concerns outlined in the LWP and
RWP and include:
• Restore stream and floodplain interaction and geomorphically stable conditions by reconnecting
historic flow paths and promoting more natural flood processes,
• Improve and protect water quality by reducing streambank erosion, nutrient and sediment inputs,
• Restore and protect riparian buffer functions and habitat connectivity in perpetuity by recording
a permanent conservation easement,
• Implement agricultural BMPs to reduce nonpoint source inputs to receiving waters.
To accomplish these site-specific goals, the following function -based objectives will be measured and
included with the performance standards to document overall project success as described in the table
below:

2.3 Project History, Contacts, and Timeframe
The chronology of the project history and activity is presented in Table 2. Relevant project contact
information is presented in Table 3. Relevant project background information is presented in Table 4. The
final mitigation plan and PCN were submitted to DMS September 29, 2017 for submission to the NCIRT.
The Section 404 General (Regional and Nationwide) Permit Verification was issued January 12, 2018.
Project construction started on March 23, 2018 and mitigation site earthwork and mitigation site planting
were completed on May 5, 2018, both by RiverWorks Construction. Trueline Surveying, PC completed the
as -built survey in June 2018. WLS completed the installation of baseline monitoring devices on May 14,
2018 and the installation of survey monumentation and conservation easement boundary marking on
August 13, 2018.
Refer to Figure 1 and Table 1 for the project components/asset information. A recorded conservation
easement consisting of 10.96 acres protects and preserves all stream reaches, existing wetland areas, and
riparian buffers in perpetuity.
3 Project Mitigation Components
3.1 Stream Mitigation Types and Approaches
Stream restoration practices involved raising the existing streambed and reconnecting the stream to the
relic floodplain. Some portions of the existing degraded channels that were abandoned within the
restoration areas were filled to decrease surface and subsurface drainage and raise the local water table.
The project also included restoring, enhancing and protecting riparian buffers and riparian wetlands
within the conservation easement. The vegetative components of this project included stream bank,
floodplain, and transitional upland zones planting. The Site was planted with native species riparian buffer
vegetation (Appendix C) and now protected through a permanent conservation easement. Table 1 and
Figure 1 (Appendix A) provide a summary of the project components.
3.1.1 R1 Preservation
Preservation was implemented along this reach since the existing stream and wetland system is mostly
stable with a mature riparian buffer due to minimal historic impacts. The preservation area is being
protected in perpetuity through a permanent conservation easement. This approach will extend the
wildlife corridor from the Buffalo Creek floodplain boundary throughout a majority of the riparian valley,
while providing a hydrologic connection and critical habitat linkage within the catchment area.
3.1.2 R2 Restoration
Work along R2 involved a Priority Level I Restoration approach by raising the bed elevation and
reconnecting the stream with its abandoned floodplain. This approach will promote more frequent over
bank flooding in areas with hydric soils, thereby creating favorable conditions for wetland re-
establishment. The reach was restored using appropriate riffle -pool morphology with a conservative
meander planform geometry that accommodates the valley slope and width. This approach allowed
restoration of a stable channel form with appropriate bedform diversity, as well as, improved biological
functions through increased aquatic and terrestrial habitats. Proposed in -stream structures included
constructed wood riffles for grade control and habitat, log j -hook vanes, and log weirs/jams for
encouraging step -pool formation energy dissipation, bank stability, and bedform diversity. Riparian
Edwards -Johnson Mitigation Project
FINAL Monitoring Report Year 1 Page 3

buffers greater than 50 feet were enhanced and will be protected along the entire length of R2. Mature
trees and significant native vegetation were protected and incorporated into the design.
Bioengineering techniques such as vegetated geolifts and live stakes were also used to protect
streambanks and promote woody vegetation growth along the streambanks. The existing unstable
channel was filled to an elevation sufficient to connect the new bankfull channel to its active floodplain
using suitable fill material excavated from the newly restored channels and remnant spoil piles.
Additionally, water quality treatment basins were installed to reduce direct sediment and nutrient inputs.
3.1.3 R3 (Upper Reach) Restoration
A Priority Level I Restoration approach was implemented for the upstream portion to improve stream
functions and water quality. Prior to restoration activities, the reach exhibited both lateral and vertical
instability, as shown by active headcuts and moderate bank erosion. A new single -thread meandering
channel was constructed offline in this area before reconnecting with multiple relic channel features and
the existing channel alignment farther downstream. In -stream structures, including log riffles, log weirs
and log vanes were used to dissipate flow energy, protect streambanks, and eliminate potential for future
incision. Shallow floodplain depressions and vernal pools were created or preserved in the floodplain to
provide habitat diversity, nutrient cycling, and improved treatment of overland flows. Restored
streambanks were graded to stable side slopes and the floodplain was reconnected to further promote
stability and hydrological function.
3.1.4 R3 (Lower Reach) Preservation
Preservation was implemented along this reach since the existing stream and wetland system is mostly
stable with a mature riparian buffer due to minimal historic impacts. The preservation is being protected
in perpetuity through a permanent conservation easement. This approach will extend the wildlife corridor
from the Buffalo Creek floodplain boundary throughout a majority of the riparian valley, while providing
a hydrologic connection and critical habitat linkage within the catchment area.
3.1.5 R4 Restoration
The restoration of R4 involved raising the existing bed elevation gradually to reconnect the stream with
its active floodplain. Prior to restoration activities, the existing channel began experiencing backwater
conditions and sediment aggradation from a man-made pond. The failing dam and remnant spoil piles
were removed and the pond was drained to reconnect the new stream channel with its geomorphic
floodplain. Channel and floodplain excavation in this reach segment included the removal of shallow
legacy sediments (approx. 12" depth) to accommodate a new bankfull channel and in -stream structures,
as well as a more natural step -pool morphology using grade control structures in the steeper transitional
areas. Shallow floodplain depressions were created to provide habitat diversity, nutrient cycling, and
improved treatment of overland flows. Riparian buffers greater than 50 feet were restored and protected
along all R4.
3.2 Wetlands Mitigation Types and Approaches
Wetland mitigation credits are not contracted or proposed for this project.

4.1 Streams
4.1.1 Stream Hydrology
Two separate bankfull events must be documented within the seven-year monitoring period. These two
bankfull events must occur in separate years. Otherwise, the stream monitoring will continue until two
bankfull events have been documented in separate years. In addition to the two bankfull flow events, two
"geomorphically significant" flow events ((Dg,=0.66Q2) must also be documented during the monitoring
period. There are no temporal requirements regarding the distribution of the geomorphically significant
flows.
4.1.2 Stream Profiles, Vertical Stability, and Floodplain Access
Stream profiles, as a measure of vertical stability will be evaluated by looking at Bank Height Ratios (BHR).
The BHR shall not exceed 1.2 along the restored project reaches. This standard only applies to the restored
project reaches where BHRs were corrected through design and construction. In addition, observed
bedforms should be consistent with those observed for channels of the design stream type(s). Vertical
stability and floodplain access will both be evaluated by looking at Entrenchment Ratios (ER). The ER shall
be no less than 2.2 (>1.5 for "B" stream types) along the restored project stream reaches. This standard
only applies to restored reaches of the channel where ERs were corrected through design and construction.
4.1.3 Stream Horizontal Stability
Cross-sections will be used to evaluate horizontal stream stability. There should be little change expected
in as -built restoration cross-sections. If measurable changes do occur, they should be evaluated to
determine if the changes represent a movement toward a more unstable condition (e.g., downcutting,
erosion) or a movement towards increased stability (e.g., settling, vegetation establishment, deposition
along the streambanks, decrease in width/depth ratio). Cross-sections shall be classified using the Rosgen
Stream Classification method and all monitored cross-sections should fall within the quantitative
parameters defined for channels of the design stream type.
4.1.4 Streambed Material Condition and Stability
After construction, there should be minimal change in the particle size distribution of the streambed
materials, overtime, given the current watershed conditions and future sediment supply regime. Since the
streams are predominantly sand -bed systems with minimal fine/coarse gravel, some coarsening is
anticipated after restoration activities, however significant changes in particle size distribution are not
expected.
4.1.5 Jurisdictional Stream Flow
The restored stream systems must be classified as at least intermittent, and therefore must exhibit base
flow for some portion of the year during a year with normal rainfall conditions as described in the approved
mitigation plan.
4.2 Vegetation
Vegetative restoration success for the project during the intermediate monitoring years will be based on
the survival of at least 320, three-year-old planted trees per acre at the end of Year 3 of the monitoring
period and at least 260, five-year-old, planted trees per acre at the end of Year 5 of the monitoring period.
The final vegetative restoration success criteria will be achieving a density of not less than 210, seven-
year-old planted stems per acre in Year 7 of monitoring. Planted vegetation (for projects in coastal plain
and piedmont counties) must average seven (7) feet in height at Year 5 of monitoring and ten (10) feet in
Edwards -Johnson Mitigation Project
FINAL Monitoring Report Year 1 Page 6
Water & Land Solutions 4
height at Year 7 of monitoring. For all of the monitoring years (Year 1 through Year 7), the number of
Red maple (Acer rubrum) stems cannot exceed 20% of the total stems in any of the vegetation monitoring
plots.
4.3 Wetlands
Wetland mitigation credits are not contracted or proposed for this project. Wetland mitigation
performance standards are therefore not included in this section.
5 Monitoring Year 1 Assessment and Results
Annual monitoring was conducted during MY1 in accordance with the monitoring plan as described in the
approved mitigation plan and was intended to document the site improvements based on restoration
potential, catchment health, ecological stressors and overall constraints. All of the monitoring device
locations are depicted on the CCPV (Figure 1). MY1 monitoring results are provided in the appendices.
The Project meets the MY1 success criteria for stream hydrology, stream horizontal and vertical stability,
and streambed material. All vegetation plots meet interim success criteria except veg plot 3 which
appears to be experiencing prolonged wet conditions
5.1 Stream Hydrology
Monitoring to document the occurrence of the two required bankfull events (overbank flows) and the two
required "geomorphically significant" flow events (Qgs=0.66Q2) within the monitoring period, along with
floodplain access by flood flows, is being conducted using a crest gauge, installed on December 12, 2018,
on the floodplain of and across the dimension of the restored channel at the left top of bank of Reach R2,
immediately upstream of the confluence of Reach R2 and R4 (Figure 1), to record the watermark
associated with the highest flood stage between monitoring site visits. Photographs are also being used
to document the occurrence of debris lines and sediment deposition on the floodplain during monitoring
site visits. Because the crest gage was installed after the submission of the Draft As -built Baseline
Monitoring Reports and Draft Monitoring Reports Year 1, only the described photographic measures will
be used for Year 1 stream hydrologic monitoring. At least one bankfull events occurred during MY1. This
event was documented using the described photography (Table 8). The documented occurrence of this
flow event satisfies the requirement of the occurrence of one of the two bankfull events (overbank flows)
and the one of the two "geomorphically significant" flow events (Qgs=0.66Q2) within the monitoring
period, along with floodplain access by flood flows.
5.2 Stream Horizontal & Vertical Stability
Visual assessment was utilized for assessment of MY1 horizontal and vertical stream stability. The visual
assessments for each stream reach concluded that the MY1 stream channel pattern and longitudinal
profiles, instream structure locations, still closely match the profile design parameters and MYO/baseline
conditions. The MY1 plan form geometry or pattern still appears to fall within acceptable ranges of the
design parameters for all restored reaches. Only minor channel adjustments in riffle slopes, pool depths
and pattern were observed and therefore did not present a stability concern or indicate a need for
remedial action.
5.3 Streambed Material Condition and Stability
A representative sediment sample was collected to assess streambed material condition and stability. The
dominant substrate for the project was verified as coarse sand. The post -construction riffle substrate
Edwards -Johnson Mitigation Project
FINAL Monitoring Report Year 1 Page 7
Water & Land Solutions 4
sampling indicated no significant change (e.g., aggradation, degradation, embeddedness) in streambed
material condition or stability were observed during MY1.
5.4 Jurisdictional Stream Flow Documentation
Jurisdictional stream flow documentation and monitoring of restored intermittent reaches includes a
combination of photographic documentation and the installation of a monitoring gage (flow gage)
(continuous -read pressure transducers) within the thalweg (bottom) of the channel towards the middle
portion of the Reach R4 (Figure 1). Additionally, to determine if rainfall amounts are normal for the given
year, precipitation data was obtained from the Johnston County weather station (COOP 317994),
approximately twenty miles south of the site. The monitoring gage data for MY1 is incomplete and will be
reconciled for MY2. The monitoring gage intended to document that the stream exhibited surface flow for
a minimum of 30 consecutive days throughout some portion of the year during a year with normal rainfall
conditions. WLS did observe stream flow along Reach R4, as well as along all of other project reaches,
during each pre- and post -construction site visit in 2018, with WLS staff visiting the site on a monthly basis.
These observations correspond do the monitoring flow gage documentation results at the nearby Lake
Wendell and Pen Dell Mitigation Project Sites.
5.5 Vegetation
Vegetation monitoring for MY1 was conducted utilizing the four (4) vegetation monitoring plots, with
monitoring conducted in accordance with the CVS-EEP Level I & II Monitoring Protocol (CVS, 2008) and
DMS Stream and Wetland Monitoring Guidelines (DMS, 2017). See Figure 1 in Appendix B for the
vegetation monitoring plot locations. The MY1 average surviving planted stem density is 496 stems per
acre, which exceeds the interim measure of vegetative success of at least 320 planted stems per acre at
the end of the third monitoring year. Summary data and photographs of each plot can be found in
Appendix 3. The MY1 vegetation monitoring was also conducted utilizing visual assessment along all of
the Project stream reaches. The results of the visual assessment did not indicate any significant negative
changes to the existing vegetation community.
An area of concern was observed along R3 buffer near veg plot 3 as shown on the CCPV. This area was
utilized as a partial haul road during construction and experienced prolonged wetness during planting
activities. Veg plot 3 stem density was approximately 283 stems per acre which is below the interim
success criteria. In addition, low stem density was observed along R4 near veg plot 4. These areas will be
watched closely during MY2 monitoring and any remedial actions, if necessary, will be documented in the
subsequent MY2 report. In addition, a slight buffer encroachment was observed along the R2 as shown
on the CCPV. The conservation easement is marked in this area and the landowner has been notified.
This area will be replanted in Winter 2019 and documented in the MY2 report.
5.6 Wetlands
Wetland mitigation credits are not contracted or proposed for this project. One groundwater monitoring
well was installed during the baseline monitoring within an existing wetland area along Reach R3. The
well data was unrecoverable and therefore an additional groundwater monitoring well was installed along
Reach R3 (preservation) after the first year of monitoring, in early January 2019. The wells were installed
to document groundwater levels within the stream and wetland restoration for reference and comparison
to the preservation areas, at the request of the NCIRT (DWR). No performance standards for wetland
hydrology success was proposed in the Mitigation Plan and therefore wetland mitigation monitoring is
not included for this project.

RE: WLS Responses to NCDEQ DMS Review Comments for Task 6 Draft Baseline Monitoring Report and Task 7
Draft Monitoring Report Year 1 for the Edwards -Johnson Mitigation Project, NCDEQ DMS Full -Delivery Project ID
#97080, Contract #6825, Neuse River Basin, Cataloging Unit 03020201, Johnston County, NC
Dear Ms. Crocker:
Water & Land Solutions, LLC (WLS) is pleased to present the Final Baseline Monitoring Report and Final Monitoring Report
Year 1 for the Edwards -Johnson Mitigation Project to the North Carolina Department of Environmental Quality (NCDEQ)
Division of Mitigation Services (DMS). The Final Baseline Monitoring Report and the Final Monitoring Report Year 1 were
developed by addressing NCDEQ DMS's review comments.
Under this cover, we are providing the required three (3) hard copies of the Final Baseline Monitoring Report and the Final
Monitoring Report Year 1, and the required digital data for each (the .pdf copies of the entire updated reports and the
updated digital data) via CDs. We are providing our written responses to NCDEQ DMS's review comments on the Draft
Baseline Monitoring Report and Draft Monitoring Report Year 1 below. Each of the DMS review comments is copied below
in bold text, followed by the appropriate response from WLS in regular text:
Field Notes:
DMS Comment: Update posts and/or signage up to specifications in the lower wooded section. Ensure
locations are correct. WLS Response: All conservation easement boundary marking has been re -installed and/or
corrected to meet or exceed the specifications as set forth in the NCDEQ DMS "Survey Requirements for Full Delivery
Projects", Version 08/13/13, with the installation including the following:
• Posts:
■ Type: Steel U -channel.
■ Length: 8 foot total length, with posts drive -installed approximately 2 feet deep to provide an
installed height of approximately 6 feet above the ground.
■ Weight: 2lbs/ft.
■ Coating: Factory coated with dark green enamel and at least 6 inches of the top of the post painted
bright yellow.
• Signs:
■ Type: Standard NCDEQ DMS aluminum conservation easement signs supplied by Voss Signs.
■ Spacing: Signs installed at each conservation easement corner, approximately 1 foot outside of each
conservation easement corner marker. Signs installed as necessary along conservation easement
boundary lines, between conservation easement corners, such that the maximum sign spacing
interval is 200 feet.
• Post attachment: 3/8" aluminum drive rivets.
DMS Comment: If desired for future reports, extend XS -7 further across the headwater valley to capture
potential future stream movement. Update cross section to reflect this in MYO and baseline if desired. WLS
Response: WLS will plan to extend the horizontal limits of Cross Section 7 at Reach R3 Lower, as suggested, during
Monitoring Year 2 to more completely span the headwater stream valley for monitoring potential stream dimension
adjustments.
DMS Comment: GPS wetland reference gauge and locate in proper location on CCPV and provide updated
shapefile. WLS Response: WLS has field located the wetland reference gauge as shown on the updated CCPV map. We
have included the wetland gauge location with the GIS shapefiles in the correct projections.
DMS Comment: Crest gauge shown in field is not shown on CCPV. Capture this shape and add to CCPV and
provide shapefile. WLS Response: WLS has field located the crest gauge as shown on the updated CCPV map. We
have included the crest gauge location with the GIS shapefiles in the correct projections.
Electronic Deliverables:
• DMS Comment: DMS does not need Adobe files of any tables or graphs because they are available in the report
in that format. Remove from deliverable submittals. Raw files are required. WLS Response: WLS will removed
Adobe pdf files from future deliverable submittals as requested.
• DMS Comment: Hydro folder in support file appears to be from another project. Update. WLS Response: The
correct data had been added to the Hydro Folder as requested.
• DMS Comment: Provide the wetland reference gauge, crest gauge from MYO; provide encroachment shapefile,
vegetative areas of concern for MY1. WLS Response: WLS has included referenced features with the GIS shapefiles
in the correct projections as shown on CCPV.
• DMS Comment: Provide a shapefile of the stream asset that matches the asset table (from Mitigation Plan
shapes). This asset file should match the linear feet of credit in the original asset table and be broken out and
attributed (in the attribute table) by stream reach just like the Table 1. WLS Response: WLS has corrected the
shapefile and verified the stream lengths match the assets presented in Table 1.
• DMS Comment: The As -built center line does not match the as -built table (Table 1). Update shapefile to cut
out any asset outside the easement and attribute each feature to match Table 1 in the attribute table. WLS
Response: WLS has corrected the shapefile and verified the stream lengths match the assets presented in Table 1.
• DMS Comment: As a note, once DMS receives and approves GIS data for asset and monitoring features, the only
shapes that will be required in future submissions are vegetative areas of concern. WLS Response: WLS
appreciates the clarification and will make sure to provide the correct GIS data as required for the future submissions.
As -Built Report:
1. DMS Comment: Add the DWR number on the cover page (DWR 2016-0404). WLS Response: The NCDEQ DWR
Project Number (NCDEQ DWR Project # 2016-0404) has been added as requested to the cover page for the As -built
Baseline Monitoring Report and Monitoring Report Year 1 where previously missing.
2. DMS Comment: Page 1 and 2, WLS lists 3,781 linear feet of stream, but the numbers in the tables don't add up
to that. Where is that number from? Please correct and update. WLS Response: WLS has corrected and verified
the stream lengths match the assets presented in Table 1.
3. DMS Comment: Page 1 and 2, the LWP goals and site-specific goals are duplicated on these pages. Remove the
sets in the Project Objective and just keep in the Mitigation Objective section. WLS Response: The referenced
language regarding LWP goals and site specific goals have been removed from Section 1 Project Summary as requested.
4. DMS Comment: Page 3, the Objectives and Performance standards listed in this bullet list do not match the
Mitigation Plan. See page 2S and S2 of your Mitigation Plan. Why is WLS proposing to add items to document
project success? You can use these same tables from Mitigation Plan in all your future reports to avoid
confusion if desired. WLS Response: Sub -section 2.2 Mitigation Project Goals and Objectives and Section 4
Performance Standards have been revised as requested to match those in the approved final mitigation plan, including
the addition of the referenced tables from the approved final mitigation plan.
S. DMS Comment: Page 2, 2.3 this first paragraph contains dates that don't match the dates on the Table 2.
Update table and/or section to reflect accurate dates that match. WLS Response: All references to dates in each
of the As -built Baseline Monitoring Reports and Monitoring Reports Year 1 and in Table 2, have been checked and
edited/corrected as necessary for consistency, as requested.
6. DMS Comment: Page 2, 2.3, paragraph 2, please remove first two sentences and reference to WLS contract as
this is not relevant to report and does not match asset table in Mitigation Plan or As -built, nor does it reflect
project assets. WLS Response: The referenced sentences have been removed from the Sub -section 2.3 Project
History, Contacts, and Timeframe as requested.
7. DMS Comment: Page 11, 6.1, the dates in this first paragraph don't match the dates on Table 2. Update table
and/or section to reflect accurate dates that match. WLS Response: All references to dates in each of the As -built
Baseline Monitoring Reports and Monitoring Reports Year 1 and in Table 2, have been checked and edited/corrected
as necessary for consistency, as requested.
B. DMS Comment: Page 11, 6.3.1.1, Does WLS want to indicate this field change decision was discussed via phone
with Andrea Hughes or the update to a wider easement because of decision? OK as is, just thought it might be
good for record if desired. WLS Response: WLS edited the referenced language Sub -section 6.3.1.1 Stream
Horizontal Pattern & Longitudinal Profile, as suggested, to read as follows: "During project construction, the alignment
of the lower end of R3 and the corresponding conservation easement boundaries were revised slightly from what was
proposed to in the approved final mitigation plan. This section of R3 was restored by re -diverting the reach flow to
the historic abandoned multi -thread channel (approximate stations 33+07.35 to 37+43.92), rather than constructing
the new single thread alignment proposed in the approved final mitigation plan. This field adjustment restored a more
natural diffuse flow pattern within the topographic low -point of the valley while minimizing disturbance to existing
jurisdictional wetlands and native species vegetation in this area. The described field adjustment was discussed by
phone with and approve by Andrea Hughes (USACE, NCIRT) in early May 2018 immediately prior to implementation.
See appendices for as -built plans."
9. DMS Comment: Table 1. If you are using Mitigation Plan numbers for the assets on this project, update total
Stream Linear feet to match that (2,949 instead of 2,934). WLS Response: WLS has corrected and verified the
stream lengths match the assets presented in Table 1.
10. DMS Comment: Add a footnote below Table 1 indicating that you will use Mitigation Plan numbers for project
assets. WLS Response: The following footnote has been added to Table 1 as suggested: "Mitigation Credits are from
the final approved mitigation plan, as verified by the as -built survey."
11. DMS Comment: Page 12, Vegetation section and Revegetation Plan in As -Built drawings: Please indicate the
area that was planted (how much area planted and where on map) and if there were any changes from the
planting plan. This should be where you show any substitutions. For instance, 'winterberry' was not on
planting plan but in Table 6 as planted, and the vegetation plots are only showing 9 of the proposed 19 plants
proposed. Use a red line if they were not all used and add any substitutions. This will be helpful with
volunteers (of the same planted species) if you need to meet success with them in the future. Can add a table
if this would be helpful. WLS Response: WLS Response: The Revegetation Plan Sheets in the as -built plan set depict
the as -built planted areas correctly, as depicted with the planting zone hatching, as shown in the planting zone legend
on each sheet. The planting schedule on the Revegetation Plans has been "redlined", as requested, to reflect the
referenced plant substitutions (a total of 1 species deletion and 3 species substitutions).
12. DMS Comment: Morphological Table R3 (Upper), it appears you may have the max and min of the dimensions
parameters switched (max showing min and vis versa). Double check this is correct. WLS Response: WLS has
corrected the stream dimensions min/max in the morphological tables.
MY1 Report:
1. DMS Comment: See comments 1-7,9, and 10 from MYO report above and update MY1 with same. WLS Response:
The referenced DMS comments listed and addressed herein, along with the corresponding edits, corrections, and
additions made to the As -built Baseline Monitoring Reports, have also been addressed and made, respectively, as
appropriate, to the Monitoring Reports Year 1 Reports as requested.
2. DMS Comment: Page 1, last paragraph: first paragraph contains dates that don't match the dates on the Table
2. Update table and/or section to reflect accurate dates that match. WLS Response: All references to dates in
each of the As -built Baseline Monitoring Reports and Monitoring Reports Year 1 and in Table 2, have been checked and
edited/corrected as necessary for consistency, as requested.
3. DMS Comment: Page 7, Bankfull events, please reference Table 8 for verification of bankfull events. Also, you
state that there were 2 events but only one is showing in the table. Table 8 in the notes sections should contain
notes (Example: how much rain occurred that date, what elevation was the crest gauge showing). Update and
clarify. WLS Response: The requested reference to Table 8 has been added to Sub -section 5.1 Stream Hydrology, as
requested, and the sub -section has been edited for clarification as follows: "Monitoring to document the occurrence of
the two required bankfull events (overbank flows) and the two required "geomorphically significant" flow events
(Qgs=0.66Q2) within the monitoring period, along with floodplain access by flood flows, is being conducted using a
crest gauge, installed December 12, 2018, on the floodplain of and across the dimension of the restored channel at the
left top of bank of Reach R2, immediately upstream of the confluence of Reach R2 and R4 (Figure 1), to record the
watermark associated with the highest flood stage between monitoring site visits. Photographs are also being used to
document the occurrence of debris lines and sediment deposition on the floodplain during monitoring site visits.
Because the crest gage was installed after the submission of the Draft As -built Baseline Monitoring Reports and Draft
Monitoring Reports Year 1, only the described photographic measures will be used for Year 1 stream hydrologic
monitoring. At least one bankfull events occurred during MY1. This event was documented using the described
photography (Table 8). The documented occurrence of this flow event satisfies the requirement of the occurrence of
one of the two bankfull events (overbank flows) and the one of the two "geomorphically significant" flow events
(Qgs=0.66Q2) within the monitoring period, along with floodplain access by flood flows."
4. DMS Comment: Page 7, jurisdictional stream flow, you can't state in a report that the site meets success criteria
for flow when your monitoring device was not functioning. This was stated on Page 1 and Page 6. Revise report
to state that this success criteria is not met or unknown for flow. WLS Response: WLS has removed the two noted
references to meeting the jurisdictional stream flow success criteria (due to flow gage malfunction), and the following
sentence has been added to the end of Sub -section 5.4 Jurisdictional Stream Flow Documentation for clarification:
"WLS did observe stream flow along Reach R4, as well as along all of other project reaches, during each pre- and post -
construction site visit in 2018, with WLS staff visiting the site on a monthly basis. These observations correspond do
the monitoring flow gage documentation results at the nearby Lake Wendell and Pen Dell Mitigation Project Sites."
5. DMS Comment: Page 8, first paragraph states that there were no negative changes to vegetation with visual
assessment but then goes on to describe some negative changes. Suggest removing this sentence as it is
misleading. WLS Response: The referenced sentence in Sub -section 5.5 Vegetation was revised as requested to read
as follows: "The results of the visual assessment did not indicate any significant negative changes to the existing
vegetation community.".
6. DMS Comment: Page 8, wetland gauge: the installation and monitoring of this device was agreed to by WLS
and DWR, although DMS advised WLS that they were not contractually required. WLS documented
understanding of installing 2 gauges on this project in their comment responses to the IRT. Can WLS provide
email or correspondence from DWR / IRT showing that a lesser number of gauges were accepted for inclusion
in the MYO and/or MY1 report? WLS Response: WLS has revised the referenced Wetlands Subsection of the As -built
Baseline Monitoring Report and Monitoring Report Year 1 to explain that the two requested and agreed upon
groundwater monitoring wells have been installed, as follows: "One groundwater monitoring well was installed during
the baseline monitoring within an existing wetland area along Reach R3. The well data was unrecoverable and
therefore an additional groundwater monitoring well was installed along Reach R3 (preservation) after the first year
of monitoring, in early January 2019. The wells were installed to document groundwater levels within the stream and
wetland restoration for reference and comparison to the preservation areas, at the request of the NCIRT (DWR)."
7. DMS Comment: Table 6, There are more species showing as planted on this table between MYO and MY1. What
is going on? Any mis-identification should be footnoted at bottom of table for clarification. Why is Red Maple
shown as planted? QA/QC both of these tables. WLS Response: For Monitoring Year 0/Baseline, the referenced
table is "Table 6., Planted Stem Counts", and for Monitoring Year 1, the referenced table is "Table 6., Planted and Total
Stem Counts". As such, the differences in the species types and numbers reported in the referenced tables between
Monitoring Year 0/Baseline and for Monitoring Year 1 reflects stem mortality and volunteer stem recruitment. WLS
does not believe that there are any species mis-identification. Red maple was planted as proposed in the final approved
mitigation plans.
8. DMS Comment: Geomorph data: XS -6 (pool) is showing signs of aggrading, but this is not discussed in the
verbiage for this report. Do you have any concerns or feel that it is necessary to mention this in the report
along with an explanation as to why this is not a big deal? WLS Response: WLS is not concerned about the
adjustments to the referenced pool cross section, as it appears to be a minor channel adjustment towards the expected
and desired stream dimension and stability. WLS used the new method for calculating adjusted BHRs. The adjusted
bankfull elevation using the comparable as -built cross-sectional is approximately two tenths and therefore the BHR
would be —0.87 (<1). The morph table parameters have been updated to reflect this change.
9. DMS Comment: Tables after 7c. are not filled out with MY1 data. Update report. WLS Response: WLS is not
sure what the issue is with the "worksheets" following Table 7C in the version of the
EJ_97080_MY1_Annual_Rep_Tables.xls file DMS received, as the original WLS file has all of the appropriate data filled
in and presented on the referenced "worksheets". Please use re -submitted version of the referenced file.
10. DMS Comment: Groundwater gauge data: is this a malfunction or purposeful omission? WLS Response: The
groundwater monitoring gage was not installed correctly by WLS and therefore no data was collected for Monitoring
Year 1. WLS has resolved this issue and groundwater monitoring will be conducted for all subsequent monitoring
years.
Other Comments:
DMS Comment: There is a lot of repetition of verbiage from the mitigation plan, which is good but cumbersome.
Much of the written information could be made into bullets or tables for a faster update of future reports and
ease of reading in terms of monitoring success. This may be a suggestion for future reports? (Example you
have a table in the Mitigation Plan that could replace all of Sections 4 (Table 22 in mitigation plan) and the

WLS will definitely take these recommendations into consideration for future reports and we sincerely appreciate the
guidance.
Please contact me if you have any further questions or comments.
