EXECUTIVE SUMMARY
Wildlands Engineering (Wildlands) completed a design bid build project at the Crooked Creek #2
Mitigation Site (Site) for the North Carolina Division of Mitigation Services (DMS) to restore and enhance
6,147 linear feet (LF) of perennial streams, enhance 1.0 acre of existing wetlands, restore and create
11.6 acres of wetlands, and restore and enhance 70,936 square feet (SF) of riparian buffer in Union
County, NC. The Site is expected to generate 3,489.6 stream mitigation units (SMUs), 8.6 wetland
mitigation units (WMUs), and 1.3 buffer mitigation units (BMU) for the Goose Creek watershed (Table
1). The Site is located off NC Highway 218 in the northern portion of Union County, NC in the Yadkin
Pee -Dee River Basin; eight -digit Cataloging Unit (CU) 03040105 and the 14 -digit Hydrologic Unit Code
(HUC) 03040105040010 (Figure 1). The project streams consist of two unnamed tributaries to Crooked
Creek, UT1 and UT2, and two reaches of the Crooked Creek mainstem (Reach A and Reach B) (Figure 2).
Crooked Creek flows into the Rocky River 4 miles northeast of the site near Love Mill Road at the Stanly
County line. The adjacent land to the streams and wetlands is primarily maintained for agricultural and
residential uses.
The Site is within a Targeted Local Watershed (TLW) in the Lower Yadkin Pee -Dee River Basin
Restoration Priority Plan (RBRP) (NCEEP, 2009). The Site is also located within the Goose Creek and
Crooked Creek Local Watershed Plan (LWP). The final watershed management plan (WMP) for Goose
Creek and Crooked Creek was completed in July 2012 (NCEEP, 2012). The stressors to watershed
function identified in the WMP were sediment pollution and increases in peak stream flows resulting in
impairments to aquatic habitat and aquatic life. Stream enhancement and restoration is identified as the
best management opportunity to offset these impacts. Other stressors identified included nonpoint
source runoff, degraded terrestrial habitat, and disconnected floodplains. Wetland enhancement and
restoration is identified as the best management opportunity to offset impacts related to these
stressors. The wetland portion of the project was identified as a specific priority in the Project Atlas that
accompanies the 2012 WMP.
The project goals established in the mitigation plan (Wildlands, 2013) were completed with careful
consideration of goals and objectives that were described in the RBRP and to address stressors
identified in the LWP. The following project goals established include:
• Improve wetland hydrologic connectivity;
• Decrease sediment input into stream;
• Create appropriate terrestrial habitat;
• Decrease water temperature and increase dissolved oxygen concentrations; and
• Decrease nutrient and adverse chemical levels.
The Site construction and as -built survey and construction was completed in 2015. Planting and baseline
monitoring activities occurred in January through February 2016. Minimal adjustments were made
during construction and specific changes are detailed in Section 5.1. Baseline (MYO) profiles and cross-
section dimensions closely match the design parameters. Cross section widths and pool depths
occasionally exceed design parameters within a normal range of variability for natural streams. The Site
has been built as designed and is expected to meet the upcoming monitoring year's success criteria.

Baseline Monitoring Document and As -Built Baseline Report -FINAL
Section 1: PROJECT GOALS, BACKGROUND AND ATTRIBUTES
1.1 Project Location and Setting
The Site is located off NC Highway 218 in the northern portion of Union County, NC (Figure 1). The Site
was originally located within three tracts of land. One tract of land is owned by Reuben and Lorna Price
(PIN 081530021) and the other two tracts are owned by Logan and Mildred Tucker, (PIN 08153002H,
08153009C). A conservation easement has been recorded on a 54.9 -acre parcel purchased in 2011 by
the State of North Carolina (PIN 08153002L) comprised of portions of the original three tracts. (Deed
Book 5665, Page 823).
The Site is located in the Yadkin Pee -Dee River Basin; eight -digit Cataloging Unit (CU) 03040105 and the
14 -digit Hydrologic Unit Code (HUC) 03040105040010 (Figure 1). Located in the Carolina Slate Belt of the
Piedmont Physiographic Province (USGS, 1998), the project watershed includes primarily agricultural
forested, and developed land. The drainage area for the project site is 24,619 acres. From US -74 East,
take 27 East/Albemarle Road. Travel on Albemarle Road approximately 8 miles to Interstate 485. Take
Interstate 485 South (Inner Loop) for approximately 3 miles to exit 44 for NC Highway 218 toward Mint
Hill. Turn left off ramp on to NC218 and follow for approximately 7 miles. The project site is located
approximately 0.85 miles after US 601/Concord Highway on the right hand side of the road.
The North Carolina Division of Water Resources (NCDWR) assigns best usage classifications to State
Waters that reflect water quality conditions and potential resource usage. Crooked Creek (NCDWR Index
No. 13-17-20) is the main tributary of the project and is at least a fourth order stream. UT1 and UT2 are
first order streams that flow into Crooked Creek. Crooked Creek has been classified as Class C waters.
Class C waters are protected for secondary recreation, fishing, wildlife, fish and aquatic life propagation
and survival, agriculture, and other uses. Crooked Creek and its UTs are located within Yadkin Pee -Dee
River Subbasin (NCDWR Subbasin 03-07-12).
The site is located within a Targeted Local Watershed (TLW) in the Lower Yadkin Pee -Dee River Basin
Restoration Priority Plan (RBRP) (NCEEP, 2009). The Site is also located within the Goose Creek and
Crooked Creek Local Watershed Plan (LWP). The final watershed management plan (WMP) for Goose
Creek and Crooked Creek was completed in July 2012 (NCEEP, 2012). The stressors to watershed
function identified in the WMP were sediment pollution and increases in peak stream flows resulting in
impairments to aquatic habitat and aquatic life. Stream enhancement and restoration is identified as the
best management opportunity to offset these impacts. Other stressors identified included nonpoint
source runoff, degraded terrestrial habitat, and disconnected floodplains. Wetland enhancement and
restoration is identified as the best management opportunity to offset impacts related to these
stressors. The wetland portion of the project was identified as a specific priority in the Project Atlas that
accompanies the 2012 WMP.
Prior to construction activities, the streams on the Site had been channelized to provide drainage for
surrounding pasture. The adjacent floodplain wetland areas had been cleared and ditched. Land use
activities resulted in bank instability due to erosion and livestock access, lack of riparian buffer, and
altered hydrology. Incision, lateral erosion, and widening resulted in degraded aquatic and benthic
habitat, reduction in quality and acreage of riparian wetlands, and lowered dissolved oxygen levels in
the stream. Table 4 in Appendix 1 and Table 6 in Appendix 2 present the pre -restoration conditions in
more detail.

Baseline Monitoring Document and As -Built Baseline Report- FINAL 1-1
1.2 Project Goals and Objectives
This mitigation site is intended to provide numerous ecological benefits within the Yadkin Pee -Dee
Basin. While many of these benefits are limited to the Crooked Creek project area, others, such as
pollutant removal, reduced sediment loading, and improved aquatic and terrestrial habitat, have
farther -reaching effects. Expected improvements to water quality and ecological processes are outlined
below as project goals and objectives. These project goals established were completed with careful
consideration of goals and objectives that were described in the RBRP and to address stressors
identified in the LWP while also meeting the DMS mitigation needs.
The project specific goals of the Crooked Creek #2 Stream and Wetland Mitigation Site included the
following:
• Improve wetland hydrologic connectivity;
• Decrease sediment input into stream;
• Create appropriate terrestrial habitat;
• Decrease water temperature and increase dissolved oxygen concentrations; and
• Decrease nutrient and adverse chemical levels.
The project objectives have been defined as follows:
• Construct stream channels that will remain relatively stable over time and adequately transport
their sediment loads without significant erosion or aggradation;
• Construct stream channels that maintain riffles with coarse bed material and pools with finer
bed material;
• Provide aquatic and benthic habitat diversity in the form of pools, riffles, woody debris, and in -
stream structures;
• Add riffle features and structures and riparian vegetation to decrease water temperatures and
increased dissolved oxygen to improve water quality;
• Construct stream reaches so that floodplains and wetlands are frequently flooded to provide
energy dissipation, detain and treat flood flows, and create a more natural hydrologic regime;
• Construct fencing to keep livestock out of the streams;
• Raise local groundwater table through raising stream beds and plugging agricultural drainage
features;
• Perform minor grading in wetland areas as necessary to promote wetland hydrology; and
Plant native tree species to establish appropriate wetland and floodplain communities and
retain existing, native trees where possible.
1.3 Project Structure, Restoration Type and Approach
The final mitigation plan was submitted and accepted by the DMS in August of 2013. Construction
activities were completed in April 2015 by North State Environmental, Inc. Allied Surveying completed
the as -built survey in 2015 and Wildlands engineering completed the baseline monitoring activities in
February 2016. Planting was completed by Keller Environmental, Inc. in February 2016. Minimal
adjustments were made during construction and field adjustments made during construction are
described in further detail in section 5.1. Please refer to Appendix 1 for detailed project activity, history,
contact information, and watershed/site background information.
1.3.1 Project Structure
The project is expected to provide 3489.6 SMUs, 8.6 WMUs, and 1.3 BMUs. These project components
and mitigation credits reflect assets developed in the final IRT -approved project mitigation plan and
Crooked Creek #2 Restoration Project
Baseline Monitoring Document and As -Built Baseline Report- FINAL 1-2
subsequently permitted. Please refer to Figure 2 for the project component/asset map for the stream
and wetland feature exhibits and Table 1 for the project component and mitigation credit information
for the Site.
1.3.2 Restoration Type and Approach
The design streams were restored to the appropriate type based on the surrounding landscape, climate,
and natural vegetation communities but also with thorough consideration to existing watershed
conditions and trajectory. The project includes stream restoration and enhancement as well as wetland
enhancement, restoration and creation, and buffer restoration and enhancement. The specific proposed
stream and wetland buffer types are described below.
The stream restoration portion of this project includes one reach on one stream; UT1. This restoration
reach enters the Site from a farm field north of the site and extends to the confluence Crooked Creek.
The stream restoration design was developed based on reference conditions, representing streams
within the Southern Piedmont Belt region with similar drainage areas, valley slopes, morphology, and
bed material. The restoration reaches were designed as threshold channels. This design approach was
determined to be appropriate due to the low bedload supply and the desire to establish an immobile
channel boundary. The channels were not intended to be fully alluvial and are not expected to migrate
laterally over time. Various types of constructed riffles were installed to provide grade control and
address excess shear stress.
The stream enhancement portion of this project includes three reaches, on two streams; Crooked Creek
Reach A and B and UT2. Enhancement II consisted of cattle exclusion, extensive invasive species
removal, and planting riparian vegetation to encourage bank stabilization. Along UT2, stream banks
were also graded, stabilized, and vegetated to prevent further erosion.
The wetland enhancement portion of this projects includes two jurisdictional features (noted Wetland
AA and Wetland CC in the mitigation plan) within Zone A and Zone B. The wetland restoration portion of
this project includes an area of drained hydric soils within Zone A. The wetland creation portion of this
project includes poorly drained soils within Zone B.
Buffer restoration and enhancement was also implemented near the confluence of UT1 with Crooked
Creek. These areas were planted with native hardwood tree species and will follow a fertilization plan
that meets or exceeds the Site Specific Water Quality Management Plan for the Goose Creek Watershed
(SSWQMP, 2009).
In addition to the above credited site work, an overflow channel that is fed by Crooked Creek upstream
of the project limits was re-routed to flow back into Crooked Creek. Originally, this overflow channel
connected to UT1 before flowing back into Crooked Creek. The overflow connector cross section was
designed based on the dimensions of the surveyed cross sections collected on UT1 downstream of the
confluence. No credit was sought for this work.
1.4 Project History, Contacts and Attribute Data
The Site was restored by Wildlands through a design -bid -build contract with DMS. Tables 2, 3, and 4 in
Appendix 1 provide detailed information regarding the Project Activity and Reporting History, Project
Contacts, and Project Baseline Information and Attributes.
Crooked Creek #2 Restoration Project
Baseline Monitoring Document and As -Built Baseline Report- FINAL 1-3
Section 2: PERFORMANCE STANDARDS
The stream and wetland performance criteria for the Site follow approved performance criteria
presented in the Crooked Creek #2 Mitigation Plan (August 2013). Annual monitoring and semi-annual
site visits will be conducted to assess the condition of the finished project. The stream
restoration/enhancement reaches (Crooked Creek Reach 1, Crooked Creek Reach 2, UT1, and UT2) of
the project were assigned specific performance criteria components for stream morphology, hydrology,
and vegetation. Wetland enhancement, restoration and creation areas were assigned specific
performance criteria for wetland hydrology, and vegetation. Performance criteria will be evaluated
throughout the seven-year post -construction monitoring. If all performance criteria have been
successfully met and two bankfull events have occurred during separate years, Wildlands may propose
to DMS to terminate stream and/or vegetation monitoring after year five pending little to no prevalent
invasive species issues. An outline of the performance criteria components follows.
2.1 Stream
2.1.1 Dimension
Shallow cross-sections on the restoration reaches should be stable and should show little change in
bankfull area, maximum depth ratio, and width -to -depth ratio. Per DMS guidance, bank height ratios
shall not exceed 1.2 and entrenchment ratios shall be at least 2.2 for restored channels to be considered
stable. Shallow cross-sections should fall within the parameters defined for channels of the appropriate
Rosgen stream type. If any changes do occur, these changes will be evaluated to assess whether the
stream channel is showing signs of instability. Indicators of instability include trends in vertical incision
or bank erosion. Changes in the channel that indicate a movement toward stability or enhanced habitat
include a decrease in the width -to -depth ratio in meandering channels or an increase in pool depth.
Remedial action would not be taken if channel changes indicate a movement toward stability.
2.1.2 Pattern and Profile
Annual longitudinal profile surveys will not be conducted during the seven-year monitoring period
unless other indicators during the annual monitoring indicate a trend toward vertical and lateral
instability. Visual indicators for the stream restoration reaches should show that the bedform features
are remaining stable. Substrate
Substrate materials in the restoration reaches should indicate a progression towards or the maintenance
of coarser materials in the riffle features and smaller particles in the pool features.
2.1.3 Photo Documentation
Photographs should illustrate the Site's vegetation and morphological stability on an annual basis. Cross-
section photos should demonstrate no excessive erosion or degradation of the banks. Longitudinal
photos should indicate the absence of persistent bars within the channel or vertical incision. Grade
control structures should remain stable. Deposition of sediment on the bank side of vane arms is
preferable. Maintenance of scour pools on the channel side of vane arms is expected.
2.1.4 Bankfull Documentation
Two bankfull flow events must be documented on the restoration reaches within the seven-year
monitoring period. The two bankfull events must occur in separate years. Stream monitoring will
continue until success criteria in the form of two bankfull events in separate years have been
Crooked Creek #2 Restoration Project
Baseline Monitoring Document and As -Built Baseline Report- FINAL 2-1
documented. Bankfull events will be documented using crest gages, photographs, and visual
assessments such as debris lines.
2.2 Vegetation
The final vegetative success criteria will be the survival of 210 planted stems per acre in the planted
riparian and wetland corridor at the end of the required monitoring period (MY7). The interim measure
of vegetative success for the Site will be the survival of at least 320 planted stems per acre at the end of
the third monitoring year and at least 260 stems per acre at the end of the fifth year of monitoring.
Planted vegetation must average 10 feet in height in each plot at the end of the seventh year of
monitoring. If this performance standard is met by MY5 and stem density is trending towards success
(i.e., vigor), monitoring of vegetation on the Site may be terminated provided written approval is
provided by the USACE in consultation with the NC Interagency Review Team (IRT). The extent of
invasive species coverage will also be monitored and controlled as necessary throughout the required
monitoring period (year five or seven).
2.3 Wetlands
The target performance criteria for wetland hydrology will be a free groundwater surface within 12
inches of the ground surface for 16 consecutive days (7.5 percent) of the defined 227 day growing
season for Union County (March 23 through November 4) under typical precipitation conditions. This
success criterion was determined through model simulations of post restoration conditions and
comparison to an immediately adjacent existing wetland system. If a particular groundwater monitoring
gage does not meet the success criteria for a given monitoring year, rainfall patterns will be analyzed
and the hydrograph will be compared to that of the reference well to assess whether atypical weather
conditions occurred during the monitoring period.
2.4 Schedule and Reporting
Monitoring reports will be prepared in the fall of each year of monitoring and submitted to DMS. Based
on the DMS Annual Monitoring Template (April 2015), the monitoring reports will include the following:
• Project background which includes project objectives, project structure, restoration type and
approach, location and setting, history and background;
• Monitoring Map of major project elements including such items as grade control structures,
vegetation plots, permanent cross-sections, crest gages, and monitoring wells with current
stream, vegetation, and wetland conditions;
• Photographs showing views of the restored Site taken from fixed point stations;
• Project asset stability and easement encroachment assessment based on the cross-section
surveys and semi-annual visual assessments;
• Vegetative data as described above including the identification of any invasion by undesirable
plant species;
• Groundwater gage attainment;
• A description of damage by animals or vandalism;
• Maintenance issues and recommended remediation measures will be detailed and documented;
and
• Wildlife observations.
Crooked Creek #2 Restoration Project
Baseline Monitoring Document and As -Built Baseline Report- FINAL 2-2
Section 3: MONITORING PLAN
Monitoring will consist of collecting morphological, vegetative, and hydrological data to assess the
project success based on the restoration goals and objectives on an annual basis or until success criteria
is met. The success of the project will be assessed using measurements of the stream channel's
dimension, substrate composition, permanent photographs, vegetation, surface water hydrology, and
groundwater hydrology. Any areas with identified high priority problems, such as streambank instability,
aggradation/degradation, insufficient groundwater hydroperiod, or lack of vegetation establishment will
be evaluated on a case-by-case basis. The problem areas will be visually noted and remedial actions will
be discussed with DMS staff to determine a plan of action. Refer to Table 5 in Appendix 1 for monitoring
component summary.
3.1 Stream
Geomorphic assessments follow guidelines outlined in the Stream Channel Reference Sites: An
Illustrated Guide to Field Techniques (Harrelson et al., 1994), methodologies utilized in the Rosgen
stream assessment and classification documents (Rosgen, 1994 and 1996), and in the Stream
Restoration: A Natural Channel Design Handbook (Doll et al., 2003). Please refer to Figure 3 in Appendix
1 for monitoring locations discussed below.
3.1.1 Dimension
In order to monitor the channel dimension, four permanent cross-sections were installed along the
stream restoration reach. Two cross sections were installed per 1,000 linear feet along the stream
restoration reaches, with riffle and pool sections in proportion to DMS guidance. Each cross-section is
permanently marked with rebar installed in concrete and 1/2 inch PVC pipes. Cross-section surveys
include points measured at all breaks in slope, including top of bank, bankfull, edge of water, and
thalweg. If moderate bank erosion is observed at a stream reach during the monitoring period, an array
of bank pins will be installed in representative areas where erosion is occurring for reaches with a
bankfull width of greater than three feet. Annual cross section survey (if applicable) will be conducted
for seven years following construction. Photographs will be taken annually of the cross sections looking
upstream and downstream.
3.1.2 Pattern and Profile
Longitudinal profile surveys will not be conducted during the seven-year monitoring period unless other
indicators during the annual monitoring indicate a trend toward vertical and lateral instability. If a
longitudinal profile is deemed necessary, monitoring will follow standards as described in the DMS
Monitoring Requirements and Performance Standards for Stream and/or Wetland Mitigation
(11/7/2011) and the 2003 USACE and NCDWR Stream Mitigation Guidance for the necessary reaches.
Stream pattern and profile will be assessed visually as described below in Section 3.1.6.
3.1.3 Substrate
A reach -wide pebble count was conducted for classification purposes on the restoration reach (UT1).
Pebble counts will also be conducted at permanent riffle cross-sections. The pebble counts will be
conducted annually for seven years following construction and compared with data from previous years.
3.1.4 Photo Reference Points
A total of 34 permanent photographic reference points were established within the project stream and
wetland areas after construction. Photographs will be taken once a year to visually document stability
for seven years following construction. Permanent markers were established so that the same locations
Crooked Creek #2 Restoration Project
Baseline Monitoring Document and As -Built Baseline Report- FINAL 3-1
and view directions on the site are monitored each year. Photographs will be used to monitor
restoration and enhancement of stream and wetland areas as well as vegetation plots. The
photographer will make every effort to maintain the same area in each photo over time. Reference
photos will also be taken for each of the vegetation plots and cross-sections, and will be repeated
annually. The representative digital photo(s) shall be taken when the annual stream and vegetation
surveys are conducted.
3.1.5 Hydrology Documentation
Bankfull events will be documented using crest gages, photographs, and visual assessments such as
debris lines. Three hydrology monitoring stations with crest gages were installed; one on Crooked Creek
Reach 1, one on UTI, and one on UT2. The gages were installed within surveyed riffle cross-sections. The
gages will be checked at each site visit to determine if a bankfull event has occurred. Photographs will
be used to document the occurrence of debris lines and sediment deposition.
3.1.6 Visual Assessment
Visual assessments will be performed in the field along all stream and wetland areas on a semi-annual
basis during the seven-year monitoring period. Problem areas will be noted such as channel instability
(i.e. lateral and/or vertical instability, in -stream structure failure/instability and/or piping, headcuts),
vegetated health (i.e. low stem density, vegetation mortality, invasive species or encroachment), beaver
activity, or livestock access. Areas of concern will be mapped, photographed, and described through a
written description in the annual report. Problem areas will be re-evaluated during each subsequent
visual assessment. Should remedial actions be required, recommendations will be provided in the
annual monitoring report.
3.2 Vegetation
Planted woody vegetation will be monitored in accordance with the guidelines and procedures
developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2006) to monitor and
assess the planted woody vegetation. A total of 12 vegetation plots were established within the project
easement area. All of the plots were established as standard 10 meter by 10 meter squares. Please refer
to Figure 3 in Appendix 1 for the vegetation monitoring locations.
Vegetation plots were randomly established within the planted stream and wetland restoration areas to
capture the heterogeneity of the designed vegetative communities. The vegetation plot corners have
been marked and are recoverable either through field identification or with the use of a GPS unit.
Reference photographs at the origin looking diagonally across the plot to the opposite corner were
taken during the baseline monitoring in February 2016. Subsequent annual assessments following
baseline survey will capture the same reference photograph locations. Species composition, density and
survival rates will be evaluated on an annual basis by plot and for the entire Site. Individual plot data will
be provided and will include diameter, height, density, vigor, damage (if any), and percent survival.
Planted woody stems will be marked annually as needed based off of a known origin so they can be
found in succeeding monitoring years. Mortality will be determined from the difference between the
baseline year's living planted stems and the current year's living planted stems.
3.3 Wetlands
In order to monitor the wetland areas, 10 groundwater monitoring gages were established within the
Site using logging hydrology pressure transducers. Generally, the gages were installed at appropriate
locations so that the data collected will provide an indication of groundwater levels throughout the
wetland project area. All gages were set to record the ground water level two times per day. An onsite
rain gage will record daily rainfall and will be utilized to assess whether typical weather conditions
Crooked Creek #2 Restoration Project
Baseline Monitoring Document and As -Built Baseline Report- FINAL 3-2
occurred during the monitoring period. If a particular gage does not meet the performance standard for
a given monitoring year, rainfall patterns will be analyzed and the hydrograph will be compared to that
of the reference wetlands to assess whether atypical weather conditions occurred during the monitoring
period. Permanent photograph reference points were established at 3 locations to visually document
wetland Zone A and Zone B. Permanent markers were established so that the same locations and view
directions on the Site are photographed each year. Please refer to Figure 3 in Appendix 1 for the
hydrological monitoring and photo station locations.
Crooked Creek #2 Restoration Project
Baseline Monitoring Document and As -Built Baseline Report- FINAL 3-3
Section 4: AS -BUILT CONDITION (BASELINE)
The Site construction and as -built surveys were completed in 2015. The survey included developing an
as -built topographic surface, locating the channel boundaries, and structures. For comparison purposes,
during the baseline assessments, reaches were divided into assessment reaches in the same way that
they were established for design parameters: Crooked Creek Reach A, Crooked Creek Reach B, UT1, and
UT2.
4.1 Record Drawings
A sealed half-size record drawing is located in Appendix 5 that includes redlines for any significant field
adjustments made during construction that were different from the design plans. Minor stream
adjustments made during construction were associated with, instream habitat improvement, necessary
avoidance of existing vegetation and erosion prevention measures. Specific changes are detailed below:
4.1.1 Crooked Creek Reach 1
UT1 Overflow connector alignment shifted 15 ft to the west to avoid 5 ft diameter hardwood
tree missed during prior survey;
• Additional Invasive plant removal over all non -planted areas. (Change order #2).
4.1.2 Crooked Creek Reach 2
• Additional Invasive plant removal over all non -planted areas. (Change order #2).
4.1.3 UT1
• Station 100+25 —101+25 (approx.): added a 85 LF barbed wire fence to replace 80 LF chain link
fence removed during the construction of UT1;
• Station 116+15 — 117+00 (approx.): installed additional coir matting to floodplain;
• Additional Invasive plant removal over all non -planted areas. (Change order #2).
4.1.4 UT2
• Station 303+45: installed boulder step pool at outlet of the Wetland CC confluence with UT2
(Change Order #1);
• Additional Invasive plant removal over all non -planted areas. (Change order #2).
4.2 Baseline Data Assessment
Baseline monitoring (MYO) was conducted in January and February 2016 with the vegetation data
collection occurring in February 2016 immediately following planting. The first annual monitoring
assessment (MY1) will be completed in the fall of 2016. The streams and wetlands will be monitored for
a total of seven years, with the final monitoring activities to be conducted in 2023. The close-out for the
Site will be conducted in 2024 given the success criteria is met. As part of the closeout process, DMS will
evaluate the Site at the end of the fifth year monitoring period to determine whether or not the site is
eligible to closeout following MYS. If the Site is meeting success criteria, DMS will propose to the IRT to
proceed with the closeout process.

Baseline Monitoring Document and As -Built Baseline Report- FINAL 4-1
4.2.1 Morphological State of the Channel
Morphological data for the as -built profile was collected in January -February 2016. Please refer to
Appendix 2 for summary data tables, morphological plots, and stream photographs.
Profile
The baseline (MYO) profiles closely match the profile design parameters. On the design profiles, riffles
were depicted as straight lines with consistent slopes. However, at some locations the riffle profiles
within the as -built survey are not consistent in slope due to the installation of structures and woody
debris within the streambed. The water surface slope was used to calculate all riffle slopes. Maximum
riffle slopes exceed design parameters within a short section of UT1 to bring the bed elevation down in
the approach to the Crooked Creek confluence. Additionally, maximum pool depths typically exceed
design parameters and are expected to trend towards the design depths as a result of natural deposition
over time. These variations in riffle slope and pool depths do not constitute a problem or indicate a need
for remedial actions and will be assessed visually during the CCPV site walks.
Dimension
The baseline (MYO) dimension numbers closely match the design parameters within acceptable ranges
of variation. These are reflected in the cross sections as a larger maximum pool depth. We anticipate
that over time pools may accumulate with fine sediment and organic matter. This accumulation of
sediment within pools would not be seen as an indicator of instability.
Pattern
The baseline (MYO) pattern metrics fell within acceptable ranges of the design parameters for all three
reaches. Pattern data will be evaluated in MY5 if there are any indicators through the profile or
dimension assessments that significant geomorphic adjustments have occurred.
Bankfull Events
Bankfull events recorded following completion of constructions will be reported in the Year 1
monitoring report.
4.2.2 Vegetation
The baseline (MYO) average planted density is 526 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.
Volunteer stems were noted in several of the plots, but are not included in the calculated average
planted density. The average stem density with volunteers included (total stem density) is 772 stems per
acre. Summary data and photographs of each plot can be found in Appendix 3.
4.2.3 Wetlands
Wetland photos collected at the permanent photo points during the baseline (MYO) data collection
efforts can be found in Appendix 5. Groundwater gage data will be reported in the annual monitoring
reports.

The subject project site is an environmental restoration site of
the North Carolina Department of Environmental Quality (DEQ)
Division of Mitigation Services (NCDMS) and is encompassed
by a recorded conservation easement, but is bordered 10
by land under private ownership. Accessing the site
may require traversing areas near or along the easement
boundary and therefore access by the general public is not
permitted. Access by authorized personnel of state and
federal agencies or their designees/contractors involved in
the development, oversight,and stewardship of the restoration
site is permitted within the terms and timeframes of their
defined roles. Any intended site visitation or activity by
any person outside of these previously sanctioned roles
and activites requires prior coordination with NCDMS.

General Construction Notes for all Reaches
All erosion and sediment control practices shall comply with the North Carolina Erosion and Sediment Control Planning and Design
Manual
1) Contractor will install pump -around systems to divert flow while working in live, flowing channels. The Contractor shall operate
and maintain the pump -around system 24 hours a day unless all disturbed areas within the pump -around work area can be
stabilized by the end of the work day. Contractor shall not remove pump -around systems and advance to the next work area
until the current work area is completed and stabilized.
2) No material from the off-line proposed stream channel excavation many be backfilled into the adjacent existing stream channel
until the newly -constructed proposed stream section is completed, stabilized, and the stream flow has been diverted into it, not
even if that section of old/ existing stream is being pumped.
3) In areas without a pump -around system, Contractor shall disturb only as much channel bank as can be stabilized with
temporary seeding, mulch and erosion control matting by the end of each work day.
4) When crossing an active section of new or old stream channel, a Timber Mat shall be installed according to the details and
specifications.
5) All graded areas with slopes steeper than 3:1 will be stabilized within seven working days. All other areas will be stabilized
within 14 days.
6) Locations for staging and stockpile areas and stream crossings have been provided on the Plans. Additional or alternative
staging and/or stockpile areas and stream crossings may be used by the Contractor provided that all practices comply with the
North Carolina Erosion and Sediment Control Planning and Design manual and are approved by the Engineer prior to
implementation.
7) Various types of constructed riffles are specified on the plans. Contractor shall build the specific types of constructed riffles at
locations shown on the plans. Changes in constructed riffle type must be approved by the Engineer.
8) Contractor is to make every effort to avoid damaging or removing existing trees.
9) Under no circumstances will the Contractor exceed the limits of disturbance shown on the plans.
The Crooked Creek #2 Restoration Project construction will follow the construction sequence protocol as described below, unless
otherwise noted.
Initial Site Preparation
10) Contact North Carolina "ONE CALL' Center (1.800.632.4949) before any excavation.
11) Contact Land Quality (704-663-1699) before any work begins on the project and notify them of the start date.
12) Mobilize equipment and materials to the Site.
13) Identify and establish construction entrance, staging and stockpile areas, haul roads, silt fencing, tree protection fencing and
temporary stream crossings as indicated on the Plans for work areas. Note: all construction traffic will enter the site from the
construction entrance show on the Plans at NC Highway 218.
14) All haul roads shall be monitored for sediment loss on a daily basis. In the event of sediment loss, silt fence or other acceptable
sediment and erosion control practices shall be installed. Silt fence outlets shall be located at points of low elevation or a
minimum spacing of 150 ft.
15) Set up temporary facilities, locate equipment within the staging area, and stockpile materials needed for the initial stages of
construction within the stockpile area(s).
16) Install and maintain an onsite rain gauge and log book to record the rainfall amounts and dates. Complete the self -inspection
as required by DENR permit.
UT1 Channel Construction Notes
1) Construction of UT 1 is to be done in the dry, constructing the proposed channel from upstream to downstream starting off-line at approximately STA100+60 at
the northern portion of the Site along NC Highway 218.
2) As work progresses, remove and stockpile the top 3 inches of soil from the active grading area. Stockpiled topsoil shall be kept separate for onsite replacement
prior to floodplain seeding.
3) Remove all non-native and invasive vegetation prior to beginning the channel construction.
4) Where feasible, more than one offline section may be constructed concurrently. Offline sections shall be tied online sequentially from downstream to upstream.
5) Construct the proposed stream channel to the grade specified in the cross sections and profile. Transfer coarse material from abandoned channel riffles to new
channel riffles utilizing a pump around on the existing UTI when doing so.
6) Grade the adjacent floodplain and wetland area according to grades shown on the plan.
7) Install structures (log vane, j hook rock vane, riffles, log sills, brush sills, etc.) and in -bank bioengineering such brush toe after channel grading is completed.
8) Seed (with appropriate seed mix) and straw mulch areas where the coir fiber matting is to be installed.
9) Install coir fiber matting according to specifications, using coir fiber matting ECC -213 or equivalent from STA 100+00 to STA 114+20.71 and coir fiber matting
C-600 or equivalent from STA 114+20.71 to the confluence with Crooked Creek at STA 117+17.53.
lb) Install coir fiber matting ECC -2B or equivalent on the 2(H):l (V) slope transition from floodplain to upland on the right side of UT1 approximate corresponding
stations 115+45.00 - 117+17.53.
I l) Install a pump around at the upstream end of site between the culvert and existing UT1, installing channel dikes as necessary, in order to complete tie-in grading
of the proposed UTI from the offline section to the culvert.
12) Upon completion of UT1 and stabilization, tum water into newly constructed UT1 and remove pump around.
13) Backfill abandoned channel sections with stockpiled soil according to the grades shown on the Plans. Non-native and invasive vegetation (e.g. privet, multiflora
rose, and Japanese honeysuckle) shall be removed from the existing channel prior to backfilling.
14) Prepare floodplain for seeding by applying stockpiled topsoil to the floodplain between bankfull elevation and the grading limits, ripping, and raking/ smoothing.
Seed and mulch. Any areas within the conservation easement that have not been graded shall be treated according to the planting plan.
15) Plant live stakes and herbaceous plugs on stream banks according to planting details and specifications.
Overflow Channel Construction Notes
16) Install a pump around system between the existing UT1 and Crooked Creek (UT1 existing STA 113+40) and install Channel Plug as shown on the Plans.
17) Construct the proposed Overflow Channel to the grades and profile shown on the Plans.
18) Install structures (e.g. constructed riffle and rock sills) after channel grading is completed.
19) Seed (with appropriate seed mix) and straw mulch areas where the coir fiber matting is to be installed.
20) Install coir fiber matting C-600 or equivalent
21) Upon completion of the Overflow Channel, turn water into the newly constructed Overflow Channel and remove the pump around.
22) Backfill the abandoned channel between the Overflow Channel and newly constructed UT1 east of the Overflow Channel with stockpiled soils according to the
grades shown on the Plans. Non-native invasive vegetation (i.e. privet, multiflora rose, and Japanese honeysuckle) shall be removed from the existing channel
prior to backfilling.
23) Plant live stakes on stream banks according to the planting details and specifications.
Wetland Construction Notes
1) Finalize floodplain and wetland grading, removing haul roads as necessary.
2) Prepare floodplain for seeding by applying stockpiled topsoil to the floodplain between bankfull elevation and the grading limits, ripping, and
raking/ smoothing. Seed and mulch.
3) Install Channel Plug in the ditch in the southeast section of the site at the confluence with UT2 according to sheet 2.6 of the Plans.
4) Backfill channel with stockpiled soils according to the grades shown on the Plans. Non-native invasive vegetation (i.e. privet, multiflora rose,
and Japanese honeysuckle) shall be removed from the existing channel prior to backfilling.
5) Seed and straw mulch disturbed areas of the backfilled channel and seed according to plans and specifications.
Construction Demobilization
6) Remove temporary stream crossings.
7) The Contractor shall ensure that the site is free of trash and leftover materials prior to demobilization of equipment from the site.
8) Complete the removal of any additional stockpiled material from the site.
9) Demobilize grading equipment from the site.
10) All rock and other stockpiled materials must be removed from the limits of disturbance and conservation easement. All areas outside the
conservation easement shall be returned to pre -project conditions or better.
11) Seed, mulch, and stabilize staging areas, stockpile areas, haul roads, and construction entrances. Pasture seed mix is to be applied
to areas of disturbance outside of the conservation easement and disturbed areas that do not fall within the riparian or wetland planting
zones shown in the plantingPIan. Remove all temporary ryfencin .
