Mr. Reid:
Please find below our responses to the NC Division of Mitigation Services(DMS) review comments dated
May 9, 2022 in reference to the Blair Creek Mitigation Project's As-Built Baseline Monitoring Report. We
have revised the Draft document in response to the referenced review comments as outlined below.
Title Page:
• DWR#is incorrect. Should be 2020-1094.
• Please add RFP#16-007278(Date of Issue:June 21, 2017)
• Recommend organizing project information in a list similar to enclosed example for easier
reading. Photo size may be reduced if necessary.
Response: Changes to the Title Page were made as requested.
1.4 Mitigation Component Summary:
• Please include a discussion for the Reestablishment, Rehabilitation and Enhancement wetland
work conducted on the site. Currentlythere is no discussion involving the wetlands.
Response: A thorough discussion of the three wetland mitigation componentswere added to
this section.
1.5 Project Timeline:
• Please add the following or something similar:The Blair Creek Mitigation Project was instituted in
January 2018. The Mitigation plan was approved by the IRT in November 2020.
Response: Those statementswere added as requested.
1.6 Design Change Deviations:
• Please include a brief explanation as to why structures were omitted or substituted.Was it due to
having onsite availabilityto materials, design concerns, etc.?
Response: There are a combination of explanations for the structure changes noted in the red-
line plans. Material cost and availability were important factors,along with feedback from the
IRT over the past few years that wooden structures are generally preferred to rock when
practicable and appropriate. The design changes noted in the plans do not impact the stability

or functional uplift of the restored stream channels. In fact,significantly more large woody
material has been added to the system(replacing rock/boulders). Text has been added in this
section to explain the changes as requested.
• Section states that"The original planting plan was used by the planting contractor for ordering
resulting in a discrepancy..."This is unclear, please elaborate for clarification. Were there two
planting plans?
Response: The original planting plan was modified between the Draft and Final versions of the
Mitigation plan based on IRT comments. The planted species table was correctly revised in the
Final Mitigation Plan vegetation section as discussed in Baker's IRT response to comments
letter. However,the planted speciestable shown in the construction plans(Sheet 1-A)was
unfortunately not revised accordingly. Thus,the contractor initially began planting the original
version of the species list (which were ultimately derived from the draft mit plan). The error
was noted prior to the completion of planting and the erroneous species were removed from
planting at that point. The text has been revised in this section to clarify this issue.
• The four oaks (lyrata,phellos, pagoda, michauxii) listed in the section as planted but not approved
in the Mitigation Plan and therefore not counted to determine planted densities.These species
were included on Sheet 1-A of the approved Mitigation Plan. Please review and make corrections
as necessary.Table 5, CCPV call outs and report will need to be updated if vegetation stem/ac
totals change.
Response: Those four oakswere not actually approved in the final,revised Mitigation Plan
planted species table,though they had been incorrectly shown on the construction plan sheet
species table(as explained above). Thus,they were not considered as counting towards
vegetative success. Table 5,the CCPV, and all numbers and references to vegetation in the
report only include those species that were accepted in the final revised list of approved species
from the Mitigation Plan. Notably,despite the loss of several planted species allowed to count
towards success,allveg plots on site have high planted densities and are expected to perform
well throughoutthemonitoringperiod.
Photo Points:
• Please add date photos were taken to top of pages or include photo date stamp.
Response: Dates were added to the photo-log as requested.
Table 2:
• Remove 404 permit date line.
• Add "Project Instituted Jan-18"as the first entry in the table.
• Please add two lines below As-Built Baseline Monitoring Report (MYO)entry: "Vegetation
Monitoring" and "Stream Survey" and the dates that these activities were completed. Please
include this information for future monitoring reports.
Response: Table 2 was revised as requested.
Table 6:
• Please include grid lines in the final submittal.
Response: Grid lines were added to Table 6 as requested.

DMS conducted a field visit on May 5, 2022.The following comments/observations are a result of
that visit:
• Overall,site is performing very well.
Response: Thank you. We are also pleased with the site performance thus far.
• Two structures have scour behind vane arms; Reach 1 log cross vane,sta:24+75, and
Reach 2 log J-hook vane,sta:23+75.
Response: Yes, Baker is aware of the scour around these two structures. Winter storms prior
to the establishment of vegetation caused the damage and we are currently discussing repair
options with the contractor,which will be conducted this year and documented in the MY1
monitoring report.
• Monitoring Well#1 is located in an area approximately 1' lower than surrounding wetland
reestablishment area. Recommend adding an additional well to document hydrology
throughout reestablishment area.
Response: Well#1 was placed where it is simply because that's roughly where it was shown
on the proposed monitoringfigure in the mitigation plan. However,as noted,it is currently
found within a lower-lying portion ofa point bar,as compared to the rest of the left bank
floodplain. As this portion of the point bar is much smaller(only about 1,500ft2 or 0.03 ac)
and quite obviously wetter than the adjacent floodplain(and thus not truly representative of
the restoration area as a whole), Baker would prefer to relocate this well about 15-20 ft
farther away from the channel and into the middle ofthefloodplain where the bulk of the
wetland reestablishment is found (see proposed map below).

• Left floodplain is bare from approximatelysta: 10+50-14+00 on R1.Same area as Monitoring
Well#1. Recommend over seeding this spring and/or fall.
Response: Yes,we also noticed a comparative lack of herbaceous vegetation coming up this
spring in that area as well. We will certainly reseed here this fall.

BLAIR CREEK STREAM MITIGATION PROJECT,DMS NO.100047
AS-BUILT BASELINE MONITORING REPORT(FINAL)

1.0 PROJECT SUMMARY
1.1 Project Description
Michael Baker Engineering, Inc. (Michael Baker) restored approximately 4,293 linear feet of existing
stream along both the North and South Forks of Blair Creek and below the confluence on Blair Creek itself
and enhanced 177 linear feet of an unnamed tributary (UT)to the South Fork. Additionally,the project has
restored-by-reestablishment, restored-by-rehabilitation, or enhanced approximately 6.095 total acres of
riparian wetlands. The project is located in the Blue Ridge Physiographic Region,within the Broad Basins
Level IV ecoregion. The project watershed drains into the Hiwassee River approximately 1.4 miles
downstream,ultimately emptying into the Tennessee River. Blair Creek and its tributaries are classified by
NCDWR as Class"WS-IV"waters(NCDWR,2016).
The Blair Creek Mitigation Project (project)is located on five abutting parcels of an active farm in Clay
County,North Carolina,approximately 1.5 miles south of the Town of Hay esville as shown on the Project
Vicinity Map (Figure 1). Historic agricultural use on the project site has predominantly been for a dairy
operation and is currently utilized for row crop and hay production. These activities have negatively
impacted both water quality and streambank stability along the project streams. The resulting observed
stressors include streambank erosion, sedimentation, excess nutrient input,channel modification,wetland
drainage,and the loss of riparian buffers.
The project is being conducted as part of the NCDMS Full Delivery In-Lieu Fee Program and is anticipated
to generate a total of 4,363.37 cold stream mitigation credits and 5.772 wetland mitigation credits and will
be protected by a 10.02-acre permanent conservation easement(Appendix B).
1.2 Goals and Objectives
The goals of this project are identified below:
• Establishment of geomorphically stable conditions along all project reaches,
• Improvement of water quality by reducing nutrient and sediment inputs,
• Restoration of natural stream and floodplain interactions,
• Restoration and enhancement of riparian wetland functions,
• Restoration and protection of riparian buffer functions and corridor habitat,
• Improvement of in-stream aquatic habitat, and
• Establishment of a permanent conservation easement on the entire project.
To accomplish these goals,the following objectives were identified:
• To restore appropriate bankfull dimensions, remove spoil berms, and/or raise channel beds, by
utilizing either a Priority I Restoration approach or an Enhancement Level I approach.
• To construct streams of appropriate dimensions, pattern, and profile in restored reaches, slope
stream banks and provide bankfull benches on enhanced streams and utilize bio-engineering to
provide long-term stability.
• Construct the correct channel morphology along all stream channels, increasing the number and
depth of pools utilizing structures including geo-lifts with brush toe,log vanes/weirs,root wads,
and/or J-hooks.
MICHAEL BAKER ENGINEERING,INC. PAGE 3
BLAIR CREEK MITIGATION PROJECT,DMS NO.100047
AS-BUILT BASELINE MONITORING REPORT(FINAL)

• Raise ground water tables within the buffer through the implementation of Priority I restoration.
Wetland vegetation will also be planted.
• Establish riparian buffers at a 30 foot minimum width along all stream reaches,planted with native
tree and shrub species.
• Establish a permanent conservation easement restricting land use in perpetuity. This will prevent
site disturbance and allow the project to mature and stabilize.
1.3 Project Success Criteria
The success criteria and performance standards for the project will follow the NCDMS's templates As-
Built Baseline Monitoring Report Format,Data Requirements, and Content Guidance(June 2017),and the
Annual Monitoring Report Format, Data Requirements, and Content Guidance (June 2017), and as
described in Section 7 of the approved Mitigation Plan. All specific monitoring activities will follow those
outlined in detail in Section 8 of the approved Mitigation Plan and will be conducted for a period of 7 years
unless otherwise noted.
1.4 Mitigation Component Summary
The project involved the restoration or enhancement of four reaches, including the unnamed tributary,
Reach 1 is on the North Fork of Blair Creek and has been historically impacted and altered through
straightening and the removal of riparian vegetation and agricultural activities. As a result,it was an incised
B to E4 stream type with bank scour occurring throughout the reach.A Priority Level I restoration approach
was selected for RI to fully restore stream and associated buffer functions. The channel will be raised to
reconnect the stream to its historic floodplain. This will promote more frequent over bank flooding thus
reducing erosive stream energies during storm events greater than the bankfull discharge and will improve
adjacent groundwater hydrology. The restored channel was designed as a C4 stream type. The abandoned
channel was filled.
Reach R2 is on the South Fork of Blair Creek and was improved using a Restoration approach. This reach
flows northeast to the confluence with the North Fork of Blair Creek. It has been historically impacted
and altered through straightening and the removal of riparian vegetation and agricultural activities. Like
RI the R2 channel was very incised with an average BHR of at least 2.0 on most of the channel. The
restored channel was designed as a C4 stream type and was restored using a Priority Level I restoration
approach with meandering riffle-pool morphology.
Reach 3 begins at the confluence of Reaches 1 and 2(the North and South Forks of Blair Creek
respectively)and flows east for approximately 185 feet, ending at a right-of-way for an overhead utility
line. Reach 3 was improved using a restoration approach. A new stream channel alignment was built
with appropriate dimensions and vertical eroding banks were stabilized and sloped back to allow access to
the floodplain.
Reach UT1 was improved using an Enhancement Level II approach. This reach flows north to the
confluence with the right bank of R2. Work along UT1 involved common Enhancement Level II practices
to re-establish a woody buffer and to maintain the stability of the channel. Several in-stream structures
were installed to improve bedform diversity and stabilize the channel as it drops down slope. A few areas
of steep and eroding stream bank were sloped back,matted,and live-staked. The outfall of the culvert
under Cherry Road was stabilized,though it is located just outside of the easement. And finally,the
riparian buffers in excess of 30 feet were seeded and planted with woody species and protected along all
reaches.
Additionally,the project involved a wetland mitigation component consisting of three separate
approaches:restoration by re-establishment,restoration by rehabilitation,and wetland enhancement. The
wetland re-establishment on site involved the restoration of appropriate wetland hydrology to hydric soils

AS-BUILT BASELINE MONITORING REPORT(FINAL)

not previously located within an existing jurisdictional wetland. This was accomplished by: connecting
adjacent stream channels to their relic floodplains through Priority I stream restoration,planting a native
wetland vegetation community,removing invasive species,removing dredge spoil berms located along
stream banks,and the removal of subsurface drain pipes from wetland areas along Reach Rl.
Wetland rehabilitation was accomplished by restoring most of the historic natural functions to heavily
degraded,but still existing jurisdictional wetlands. The degradation consisted of clear impacts to both the
hydrology and vegetation functions. The wetlands were adjacent to incised streams, had drain swales and
sub-surface drain pipes present, and had their entire natural vegetation removed with no trees present. By
correcting these impacts, the rehabilitation approach will result in significant improvements to both the
wetland hydrology and vegetation functions within the existing wetland, but will not result in a gain in
wetland resource area.
Wetland enhancement was accomplished by improving a specific degraded wetland function within an
existing jurisdictional wetland, specifically to the vegetation function for this site. Enhancement of the
existing wetlands on the project primarily involved an improvement to their vegetation community,
supplementing with appropriate wetland community species,along with treatment or removal of all
invasive vegetation present. Thus,this enhancement approach will primarily result in a minor
improvement to the wetland vegetation function,but will not result in any gain in wetland resource area.
1.5 Project Timeline
The Blair Creek Mitigation Project was instituted in January 2018. The Mitigation Plan was approved by
the IRT in November of 2020. Project construction was initiated in July 2021 and completed in
December 2021. Planting of live stakes and bareroot stems was completed in February 2022 and
Monitoring Year 1 is on schedule for 2022 as shown in Table 2. The As-Built survey was completed in
January of 2022. All 15 cross-sections and 3 crest gauges and 10 groundwater wells were installed in
November 2021. The vegetation plots were installed in January of 2022.All wells,crest gauges,and the
flow gauges are continuous logging Van Essen DIVER gauges. CE pins were located and the CE
boundary was marked in March 2022.
1.6 Design Change Deviations
During project construction,there were a few,relatively minor deviations from the original design plans
as marked in red in the as-built plans(Appendix E). Primarily these were substitutions made on in-stream
structures replacing boulder structures with log structures. In some cases, a log vane was omitted and in
three locations a constructed riffle replaced a grade control log jam. These changes were made due to
material costs and availability at the time of construction,along with feedback from the IRT over the past
few years that wooden structures are generally preferred to rock when practicable and appropriate.
Significantly more large woody material has been added to the system(to replace rock/boulders). These
design changes in no way impact the stability or functional uplift of the restored stream channels.
Additionally,there were minor deviations from the final,approved planting plan,which had been
modified between the draft and final versions of the mitigation plan based on IRT comments. However,
the revised species table was not incorporated as part of the final construction plan sheets used by the
planting contractor,thus they used the older, outdated table for their bareroot orders. This error was
discovered prior to the completion of planting however,and the erroneous species were removed from
planting at that point. For this reason, some species were planted in different densities or were omitted.
Four Quercus species (lyrata,phellos,pagoda, michauxii)were planted that were not approved in the
final mitigation plan. However,only species that had been approved for planting in the final mitigation
plan were used to determine the reported vegetation plot planted densities(in Table 5,the CCPV, etc).
Likewise, only the approved species will be used for the determination of vegetation criteria success
throughout the monitoring phase of the project.

1.8 Technical and Methodological Descriptions and References
Stream survey data was collected to a minimum of Class C Vertical and Class A Horizontal Accuracy using
a Leica TS06 Total Station and was georeferencedto the NAD83 State Plane Coordinate System,FIPS3200
in US Survey Feet,which was derived from the As-built Survey. The survey data from the permanent
project cross-sections were collected and classified using the Rosgen Stream Classification System to
confirm design stream type(Rosgen 1994).
The six vegetation-monitoring quadrants(plots)were installed across the site in accordance with the
CVS-DMS Protocol for Recording Vegetation,Version 4.1 (Lee 2007)and the data collected from each
was input into the DMS Veg Table Production Tool(2021).
Ten automated groundwater monitoring wells were installed in the floodplain following USACE
protocols(USACE 2005). The gauges themselves,both flow and groundwater gauges,are all Van Essen
brand Baro-Diver data loggers.
