PAGE IV 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) 1.0 EXECUTIVE SUMMARY Michael Baker Engineering, Inc., (Baker) restored 2,785 linear feet (LF) and enhanced approximately 943 LF of jurisdictional stream along an unnamed tributary (UT) that flows into Town Creek. Baker also planted native riparian species within the 11.97 acre (AC) recorded conservation easement along the restored and enhanced reaches (Reaches 1 — 5). The Town Creek Restoration Project — Option B (Site) is located in Stanly County, approximately 1.5 miles west of the Town of New London, within cataloging unit 03040105 of the Yadkin Pee - Dee River Basin. The Project is located in a North Carolina Division of Mitigation Services (NCDMS) - Targeted Local Watershed (HUC 03040105060-040), and involved stream restoration and enhancement along a UT to Town Creek, which had been impaired due to historical pasture conversion and active cattle grazing. See Figure 1. Based on both the River Basin Restoration Priorities (RBRP) document for the Lower Yadkin — Pee Dee River Basin (NCEEP, 2009) and the Yadkin -Pee Dee River Basinwide Water Quality Plan (NCDENR, 2008), many streams in the Rocky River Watershed (03040105) are documented as impaired or impacted due to habitat degradation. Stressors identified in the plan include impervious surfaces, sedimentation and erosion from construction, general agriculture, and other land disturbing activities. As stated in the Yadkin -Pee Dee River Basinwide Water Quality Plan, the project watershed naturally consists of erodible soils; therefore, increasing the system's vulnerability to the aforementioned stressors. The primary goals of the project are as follows: Improve aquatic and terrestrial habitat through the increase of dissolved oxygen concentrations, reduction of nutrient and sediment loads, improvement of substrate and in -stream cover, reduction of stream bank erosion, and reduction of in -stream water temperature, Create geomorphically stable conditions along the channels, Enhance hydrologic connections between streams and the degraded riparian buffer and overall ecosystem functionality; Restore and protect riparian buffer functions and corridor habitat in perpetuity by establishing a permanent conservation easement. Improve terrestrial habitat and reduce sediment and nutrient loading to the project reaches and the Little Long Creek Watershed. To accomplish these goals, the project pursued the following objectives: Restore existing incised, eroding, and channelized streams by creating a stable stream channel with access to its floodplain, Improve in -stream habitat by providing a more diverse bedform with riffles and pools, creating deeper pools and areas of water re -aeration, and reducing bank erosion, Prevent cattle from accessing the project boundary by installing permanent fencing and thus reduce excessive bank erosion and undesired nutrient inputs, Plant native species riparian buffer vegetation along stream bank and floodplain areas, protected by a permanent conservation easement, to increase stormwater runoff filtering capacity, improve bank stability, and shade the stream to decrease water temperature, Control invasive species vegetation within the project area and, if necessary, continue treatments during the monitoring period. This report documents the completion of the restoration construction activities and presents as -built monitoring data for the post -construction monitoring period.

PAGE 1-1 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) 2.0 PROJECT GOALS, BACKGROUND AND ATTRIBUTES 2.1 Project Location and Description The Site is located in Stanly County, NC, approximately 1.5 miles west of the Town of New London, as shown on the Vicinity Map (Figure 1). The project is located within the Yadkin -Pee Dee River Basin and the NCDMS - Targeted Local Watershed (HUC 03040105060-040). The project is located in the Piedmont physiographic region within the Carolina Slate Belt and includes an Unnamed Tributary (UT) that flows directly into Town Creek just downstream of the project's extent. The project channel was divided into five reaches (Reach 1, Reach 2, Reach 3, Reach 4, and Reach 5) as shown in Figure 2. The United States Geologic Survey (USGS) topographic quadrangle maps (Richfield and New London) depict the stream channel (Reach 1 — Reach 5) as a dashed blue -line stream, along its entire length within the project limits. Preliminary on-site field investigations determined that 654 LF of the project channel (which included all of R1 and 291 LF of R2) was classified as an intermittent, while the remaining 3,444 LF of the channel (428 LF of R2 through R5) was classified as perennial. On-site field investigations were confirmed during an on-site jurisdictional determination field review with the United States Army Corps of Engineers (USACE). The jurisdictional determination was approved on January 2, 2014. 2.2 Site Directions To access the Site from Raleigh, take I-40 West toward Sanford/Wake Forest.

Follow Old Salisbury Rd. for approximately 2.0 miles to its intersection with Misenheimer Rd. / Steakhouse Rd. Go through the intersection and continue on Old Salisbury Rd. for approximately 0.4 miles and the Project site is on the left accessed via a paved driveway. 2,3 Project Goals and Objectives The primary goals of the project are to improve aquatic habitat degradation by improving ecologic functions and reducing non -points source loads from agricultural run-off to the impaired areas as described in the Lower Yadkin — Pee Dee RBRP and as identified below: Improve aquatic and terrestrial habitat through the increase of dissolved oxygen concentrations, reduction of nutrient and sediment loads, improvement of substrate and in -stream cover, reduction of stream bank erosion, and reduction of in -stream water temperature, Create geomorphically stable conditions along the channels, Enhance hydrologic connections between streams and the degraded riparian buffer and overall ecosystem functionality; Restore and protect riparian buffer functions and corridor habitat in perpetuity by establishing a permanent conservation easement. Improve terrestrial habitat and reduce sediment and nutrient loading to the project reaches and the Little Long Creek Watershed. MICHAEL BAKER ENGINEERING, INC. PAGE 2-1 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT -OPTION B (DMS PROJECT NO. 95026) To accomplish these goals, the project incorporated the following objectives: Restore existing incised, eroding, and channelized streams by creating a stable stream channel with access to its floodplain. Improve in -stream habitat by providing a more diverse bedform with riffles and pools, creating deeper pools and areas of water re -aeration, and reducing bank erosion. Prevent cattle from accessing the project boundary by installing permanent fencing and thus reduce excessive bank erosion and undesired nutrient inputs. Plant native species riparian buffer vegetation along stream bank and floodplain areas, protected by a permanent conservation easement, to increase stormwater runoff filtering capacity, improve bank stability, and shade the stream to decrease water temperature. Control invasive species vegetation within the project area and, if necessary, continue treatments during the monitoring period. MICHAEL BAKER ENGINEERING, INC. PAGE 2-2 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT -OPTION B (DMS PROJECT NO. 95026) 3.0 PROJECT STRUCTURE, RESTORATION TYPE AND APPROACH 3,1 Project Components The project area consists of the restoration and enhancement of a UT to Town Creek. The project is located in the Carolina Slate Belt Level IV Ecoregion of the Piedmont physiographic region. For assessment and design purposes, the project channel was divided into five individual reaches (Reach 1, Reach 2, Reach 3, Reach 4, and Reach 5). A riparian buffer of native species vegetation was established and/or protected at least 50 feet from the top of both bank along all entire project length. Lastly, cattle were excluded along all project reaches and existing riparian wetlands located within the conservation easement with the installation of permanent fencing. The reach designations have remained in the same order to be consistent throughout the document. No wetland credit is being sought for inclusion of the riparian wetlands within the conservation easement boundary. 3.2 Restoration Approach Based on the post -construction as -built survey, the project consisted of 317 LF of Restoration on Reach 1, 711 LF of Enhancement I on Reach 2, 1,621 LF of Restoration on Reach 3, 232 LF of Enhancement I on Reach 4, and 822 LF of Restoration on Reach 5. A recorded conservation easement consisting of 11.97 acres protects and preserves all stream reaches, existing wetland areas, and riparian buffers in perpetuity. The vegetative components of this project include stream bank, floodplain, and transitional upland planting and is described as the riparian buffer zone. The Site was planted with native riparian buffer species as shown in Table 7 and Table 8 (Appendix C) and is protected within the permanent conservation easement. Table 1 and Figure 2 (Appendix A) provide a summary of the project components. 3.2.1 Reach 1 Restoration A restoration approach began on Reach 1 at the property boundary. A series of boulder steps were implemented to stabilize a head cut at the property boundary and allow for a stable transition into the restored channel. The upstream 105 LF of Reach 1 was realigned to fall along the center of the valley and bankfull benches were excavated to provide floodplain connections and to restore stream functions. The newly formed channel reconnects with the existing channel alignment at Station 11+38. The remainder of the reach was constructed mostly on-line along the existing valley bottom as a Rosgen B stream type. In -stream structures included constructed riffles for grade control and aquatic habitat improvement, grade control j -hook vanes, rock step structures for stream bed/bank stability, and habitat diversity. The existing, abandoned channel was filled along its length using material excavated during construction for the restored channel. A second modification to the existing channel alignment was made near the end of R1 where a large bedrock outcrop was promoting lateral instability by diverting flows around the feature. Therefore, the channel was moved off-line to allow for the bedrock outcrop to function as bank stability and a habitat feature. Riparian buffers in excess of 50 feet were restored along all of Reach 1 and permanent fencing was installed to exclude livestock from entering the restored stream or buffer area. The buffer was planted with a diverse mix of woody and herbaceous vegetation to reestablish a native plant community. 3.2.2 Reach 2 Enhancement Level I Work on Reach 2 involved a Level I Enhancement approach for the entire reach and included the implementation of streambank stabilization measures and in -stream structures to enhance bedform morphology, provide improved connection to the floodplain, and stabilize the reach profile. In -stream MICHAEL BAKER ENGINEERING, INC. PAGE 3-1 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) structures included the use of constructed riffles for grade control and aquatic habitat improvement, grade control j -hook vanes, rock step structures for stream bed/bank stability, and habitat diversity. Riparian buffers in excess of 50 feet were restored along all of Reach 2 and permanent fencing was installed to exclude livestock from entering the restored stream or buffer area. This buffer was planted with a diverse mix of woody and herbaceous vegetation to reestablish a native plant community. Along this reach, a jurisdictional wetland area that may have historically been used as a livestock -watering pond has been preserved within the buffer. To enhance the hydrology of this wetland, the existing berm between the wetland and the channel was lowered to improve hydrologic connectivity between the channel and the riparian wetland. This reach terminates as Station 20+61 where a 48 -inch culverted stream crossing was installed to allow for livestock and farm equipment to cross the channel. Originally, the project was designed to exclude the entire crossing area from the easement; however, after initial installation of the crossing it was determined that the upstream face of the crossing embankment was too steep. Therefore, an additional eight feet was added to the upstream face of the culverted crossing, which extended the crossing into the easement by 6 feet. 3.2.3 Reach 3 Restoration Reach 3 begins immediately downstream of the easement crossing. Due to varying existing bank height ratios (BHR) that ranged from 1.0 to greater than 2.0 throughout this reach, a restoration approach was implemented in order to fully restore stream functions and floodplain connectivity. Channel banks were graded to stabilize slopes, appropriate bankfull geometry was established throughout the reach. Bankfull benches were incorporated as needed to further promote stability and re-establish floodplain connection. The channel pattern throughout this reach meanders throughout the floodplain within the valley walls and incorporates a variety of bank stabilization measures and high quality habitat features such as vegetated geolifts, toewood, and rootwads. In -stream structures such as rock and log step pools, vanes, and constructed riffle structures were installed to control grade and dissipate flow energies. The restored channel was constructed as a Rosgen "C" stream type. The existing, unstable channel was filled along its length using material excavated for construction of the restored channel. An existing stream crossing within this reach was removed. Riparian buffers in excess of 50 feet were restored along all of Reach 3 and permanent fencing was installed to exclude livestock from entering the restored stream or buffer area. The existing vegetation within the riparian corridor of this reach was preserved where feasible. The remainder of the buffer was planted with a diverse mix of woody and herbaceous vegetation to supplement the existing vegetation and establish a native plant community. In addition to these plantings, existing non-native, invasive vegetation was treated with herbicides or physically removed to control them inside the easement. 3.2.4 Reach 4 Enhancement Level I The presence of bedrock and mature trees along this reach has helped minimize vertical incision; however, previous livestock access has affected bank stability and bedform morphology. Therefore, Enhancement Level I was implemented to stabilize stream banks and to enhance bedform diversity with the installation of in -stream structures such as constructed riffles. Riparian buffers in excess of 50 feet were restored and/or preserved throughout the reach and permanent fencing was installed to exclude livestock from entering the easement. Mature woody vegetation within the riparian corridor along this reach was also preserved where feasible. The remainder of the buffer was planted with a diverse mix of woody and herbaceous vegetation to supplement the existing vegetation to establish a native plant community. In addition to these plantings, existing exotic invasive species vegetation were treated to control them within the easement. MICHAEL BAKER ENGINEERING, INC. PAGE 3-2 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) 3.2.5 Reach 5 Restoration Work along Reach 5 involved the implementation of a restoration approach to restore stream functions and floodplain connection. Stream banks were graded and planted to promote bank stability and re- establish riparian vegetation. In -stream structures such as log vanes, rock vanes, and constructed riffles were implemented to control grade, dissipate energies, and eliminate the potential for upstream channel incision, while geo-lifts and toe wood were implemented to enhance the variability of aquatic habitat. A series of rock cross vanes were implemented in the downstream extent of the reach in order to step the channel down to meet the confluence elevation of Town Creek. The restored channel was designed and constructed as a Rosgen "C" stream type. The existing, unstable channel was filled along its length using material excavated for construction of the restored channel. An existing farm crossing previously located at the upper extent of this reach was relocated downstream within the alignment of an overhead power line in order to minimize easement breaks. Along this reach, just downstream of the relocated farm road crossing, a jurisdictional wetland feature has been preserved within the right floodplain of the conservation easement. As in Reach 2, this wetland may have historically been a livestock watering pond. In order to improve the wetland's hydrologic connectivity to the channel and stabilize an existing breach in the wetland berm, the elevation of the berm was lowered and a rock -lined swale was constructed from the wetland spillway to the main channel. Riparian buffers in excess of 50 feet were restored along all of Reach 5 and permanent fencing was installed to exclude livestock from entering the restored stream or buffer area. The existing vegetation through this reach was preserved to the greatest extent possible. The buffer was planted with a diverse mix of woody and herbaceous vegetation to supplement the existing vegetation and to establish a native plant community. In addition to these plantings, existing non-native, invasive vegetation were removed and/or treated to control them within the easement. 3.3 Project History, Contacts, and Attribute Data Baker implemented the project under a full delivery contract with NCDMS to provide stream mitigation credits in the Yadkin — Pee Dee River Basin. The chronology of the project is presented in Table 2. The contact information for all designers, contractors, and relevant suppliers is presented in Table 3. Relevant project background information is presented in Table 4. Tables 2, 3, and 4 are located in Appendix A of this report. As -built stationing is outlined in the Construction Summary, below, and in Table 1 in Appendix A. 3.3.1 Construction Summary In accordance with the approved Mitigation Plan and regulatory permits (i.e., 401/404, S&EC), construction activities began in late October 2015 with site preparation, installation of sedimentation and erosion control measures, and the establishment of staging areas, haul roads, and stockpile areas. The construction contractor was Wright Contracting, LLC. (Wright). Materials were stockpiled as needed for the initial stages of construction. Suitable channel fill material and alluvium were harvested on-site from existing spoil piles and within the existing streambed. Rock material was also harvested on-site from rocky outcrops where feasible; however, some of the larger boulders came from a local quarry and brought into the project site for use. Construction equipment was equipped with Topcon GPS units to allow for the quick layout of the design plan for channel work and floodplain grading; however, survey grade stakes were also set along the extents of the floodplain and limits of disturbance to aid the grading activities. Since construction activities began during the growing season of the NC Piedmont, vegetation installation of vegetated MICHAEL BAKER ENGINEERING, INC. PAGE 3-3 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) geo-lifts, live stakes, and bare root areas were delayed until after the onset of the dormant season (November 15). Actual in -stream structure location, placement, and type varied slightly from the design plans in various sections due to exposed bedrock, as well as to promote bedform diversity, increase vertical stability, and maintain structure integrity. Additional rock lined channels and matted grass swales, not shown on the Mitigation Plan, were incorporated within the floodplain of Reach 2 and Reach 3. Originally, it wasn't anticipated that discharges from natural and stormwater drainages into the project floodplain would lead to stream bank instability; however, after multiple large rain events, it was determined that these measures were necessary to maintain the restored channel's integrity. Construction began on the upstream portion of Reach 1 at Station 10+33 where an additional boulder step was installed to stabilize an existing headcut at the property line. During the construction of Reach 1, a rock line channel was also incorporated to discharge surface flow into the reach at Station 10+80 from a hillside seep located in the left floodplain across the upstream property boundary. Work proceeded downstream. The work involved the construction of a defined single thread channel that was built mostly on-line using a pump around operation. The existing degraded channel was filled in and graded back to match the surrounding natural topographic contours. The entire length of Reach 1 was designed as a combination step -pool system. Upon completion of new channel segments and in -stream structures, coir fiber matting and permanent seeding, were installed before moving to the next section. Invasive removal was minimal throughout the buffer area along Reach 1 due to lack of vegetation along the stream bank and within the floodplain. Live stake plantings along the channel were halted at the time of initial construction until after the end of the growing season (Nov. 15th). All disturbed areas were seeded with temporary and permanent seed and mulched with straw before mobilizing downstream to Reach 2. The as -built length of Reach 1 after construction is 317 LF. Work on Reach 2 began at Station 13+50 and progressed downstream to its terminus at a newly installed culverted stream crossing at Station 20+61. Enhancement activities were implemented along Reach 2 to restore the channel to the appropriate dimension and profile of a `C4' type stream. Work was conducted on-line using a pump around operation. Structure type and placement followed the design plans; however, constructed riffles were added in multiple areas along the upstream portion of the reach to aid in grade control and improve bedfonn diversity. Upon completion of new channel segment and in -stream structures, coir fiber matting and permanent seeding, were installed before moving to the next section. As in Reach 1, invasive species removal was minimal throughout the buffer due to lack of vegetation along the stream bank and within the floodplain. Live plant material installation for bio -engineered structures was halted at the time of initial construction until after the end of the growing season (Nov. 15th). All disturbed areas were temporarily and permanently seeded and mulched with straw before work began on the farm road crossing. The as -built length of Reach 2 after construction is 711 LF. A culverted crossing (48 -inch reinforced concrete pipe (RCP)) was installed from the end of Reach 2 (Station 20+61) to the head of Reach 3 (Station 20+87). The majority of the crossing lies outside of the conservation easement. However, due to crossing stability issues, the culvert extends upstream approximately six feet into the conservation easement. This minor easement encroachment has been removed from the as -built restoration length on Reach 2 and the associated SMUs have been adjusted accordingly. The installation of the crossing in conjunction with easement fencing along Reach 2 and Reach 3 restricts cattle access to the restored stream, while still allowing for pasture rotation and farm equipment passage. Upon completion of the crossing, side slopes were stabilized and work progressed downstream. MICHAEL BAKER ENGINEERING, INC. PAGE 3-4 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) Construction on Reach 3 began by installing a boulder step just downstream of the newly installed culverted crossing to tie in the channel grade and aid in dissipating energy from flow from the pipe. Work continued downstream and involved the construction of a defined single thread channel. Due to valley constraints and exposed bedrock, the channel remains on-line for first 450 LF of Reach 3. The implementation of grade control and habitat structures were also limited to areas along this section of the Reach where bedrock was not present. Around Station 25+50, the valley begins to open up and the floodplain widens allowing for the channel to move off-line and for the more natural meandering pattern of a "C" type stream. The channel pattern throughout the remainder of Reach 3 meanders throughout the floodplain within the valley walls. A variety of bank stabilization measures and high quality habitat features were incorporated throughout the remainder of the reach to accommodate for existing constraints along the stream bed and within the floodplain such as: Adjacent wetlands, mature hardwood trees, and existing bedrock outcrops. The existing degraded channel was filled and graded to match the design topography and to promote hydrologic connectivity to the floodplain and existing riparian wetlands, while minimizing the disturbance of the wetland areas and mature hardwoods. Upon completion of the new channel, coir fiber matting and permanent seeding were installed before moving to the next section. Vegetation planting of bioengineered structures were delayed along the upstream portion of Reach 3; however, the construction of the downstream section coincided with onset of the dormant season, and were planted at the time of construction. Invasive species were removed and/or treated throughout the easement area. The as -built length of Reach 3 is 1,621. Construction enhancement activities continued downstream along Reach 4 to its terminus at Station 39+40. Work along Reach 4 was kept on-line and consisted of Enhancement Level I activities to restore the channel's dimension and profile. Construction work along Reach 4 followed the design plans; however, a long constructed riffle at the end of Reach 3 that continues into Reach 4 was extended for approximately 50 LF to help control grade within the area. The contractor did not disturb vegetation within the Enhancement area, unless it was necessary to remove existing invasive species vegetation or trees that were damaged due to bank work. Upon completion of Reach 4, coir fiber matting and permanent seeding were installed before moving to Reach 5. The as -built length of Reach 4 is 232 LF. Work along Reach 5 began at Station 39+40 and consisted of restoration activities along the Reach to Station 45+60. Within this section of the Reach, the channel was constructed a "C" type stream, mostly off-line, but intercepted the existing channel in areas within the floodplain. A pump around operation was used in the areas where the new channel intercepted the existing channel and the remainder of the existing degraded channel was filled. An existing and undersized culverted farm road crossing was relocated downstream from Station 42+00 to Station 45+61 in order to align it with an existing overhead power line and to minimize easement breaks. The culvert was replaced with a 48 -in RCP and the relocated crossing is located outside the conservation easement. Restoration continued on the downstream side of the farm road crossing. At Station 47+00, the new meandering channel converges with the existing channel and continues on- line to its confluence with the main stem of Town Creek. A series of rock cross vanes and constructed riffles are implemented throughout this section of the reach to step the channel down to the elevation of Town Creek. A pump around operation was used in the areas where the new channel intercepted the existing channel and the remainder of the existing degraded channel was filled. The floodplain was graded to match the design topography and promote the re-establishment of hydrologic connectivity to the floodplain and riparian wetlands, while minimizing the disturbance of the wetland areas and mature hardwoods. Upon completion of the new channel segment, coir fiber matting and permanent seeding were installed MICHAEL BAKER ENGINEERING, INC. PAGE 3-5 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) throughout the Reach. Invasive species were either treated or removed throughout the easement. The as -built length of Reach 5 after construction is 822 LF, which excludes the length of the RCP. All excess fill material generated during construction of all reaches was wasted and stabilized on-site in the locations and as noted in the Erosion and Sediment Control plans. All riparian buffer areas within the project boundaries are a minimum of 50 feet along both stream banks and are protected in perpetuity by a recorded conservation easement that totals 11.97 acres. Permanent cattle exclusion fencing (woven wire) was installed outside the conservation easement boundary along all reaches with access gates near each stream crossing as shown on the As-built/Record Drawing in Appendix D. In addition, Baker has installed permanent watering systems for the cattle outside of the project boundary. Minimal Site modifications involved the location and selection of some in -stream structures and bank stabilization practices. Substitutions and/or relocations were made based on existing field conditions and best professional judgment. As-built/Record Drawings depict actual surveyed areas within the project area and depict any changes from the final design plans to what was implemented on-site during construction. The As-built/Record Drawings are located in Appendix D. The as -built results for the project totaled 3,703 LF of stream and are outlined in Table 1, which excludes both stream crossings. After construction was complete, multiple large rain events in November and December 2015 exposed multiple unstable floodplain drainage features along Reach 1, Reach 2, Reach 3, and Reach 5. Therefore, prior to the removal of sediment and control measures and permanent demobilization and the onset of easement planting, Baker and Wright met on-site on January 5, 2016 to generate a punch - list of final items for completion and to discuss a strategy to best address the areas of instability while limiting re -disturbance. Work to repair areas of instability and to address outstanding punch list items began on January 11, 2016. Work began by installing two additional constructed riffles at Station at 13+70 and 14+05 to aid in grade control. Next work moved to the left floodplain of Reach 2, where a matted drainage swale was incorporated from a floodplain seep to outfall onto a constructed riffle at Station 14+60. A small rock lined trapezoidal spillway (approximately 1 — 2 feet wide) was incorporated into the design of the floodplain wetland's berm on Reach 2 to maintain channel stability as well as the floodplain wetland's integrity. The addition of this feature was strategically placed at the downstream end of the wetland berm where it would outfall into the channel across the arm of a log vane and into the downstream plunge pool. Construction work then progressed downstream on Reach 2 to stabilize the farm road crossing by extending the culvert pipe 8 LF upstream and re -grading the crossing side slopes to a flatter angle of repose and adding additional stone to the slope faces for erosion protection. Next, a trapezoidal rock - lined channel was constructed down the hillslope in the right floodplain of Reach 3. The channel was integrated into the project in order to intercept stormflows from outside the easement area and convey them onto a constructed riffle at Station 28+30. Lastly, a small rock lined trapezoidal Swale (approximately 2 — 3 feet wide) was incorporated into the design of the floodplain wetland's berm along Reach 5. The feature was incorporated into the project's design to intercept drainage from an existing breach in the wetland's berm and directed to outfall into the channel at Station 47+10 across the arm of a rock cross vane and into the downstream plunge pool. Repair work and punch list items were complete on January 14, 2016. Upon final approval from Baker, sedimentation and erosion control measures such as temporary construction entrances, rock check dams, and silt fence were removed, and all disturbed areas were stabilized with temporary and permanent seed and mulch before de -mobilizing from the Site. Baker met with NCDMS on-site on February 2, 2016 for the final construction Site walk. NCDMS approved the construction work during the visit. The planting of bare -root trees and shrubs, live stakes, vegetated geo-lifts were completed and approved on March 11, 2016. NCDMS approved the Site plantings and monitoring device installations on June 20, 2016. MICHAEL BAKER ENGINEERING, INC. PAGE 3-6 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) 4.0 PERFORMANCE STANDARDS Baker has obtained regulatory approval for numerous stream mitigation plans involving NCDMS full -delivery projects. The success criteria for the project site will follow the mitigation plan developed for this project, as well as the 2003 Stream Mitigation Guidelines (SMG). As outlined in the RFP #16-003579, all monitoring activities will follow the NCDMS Monitoring Report Template, Version 1.3 — 1/15/10, will be conducted for a period of 5 years, and will evaluate the effectiveness of the restoration and enhancement practices based on the performance success criteria outlined in the approved mitigation plan and the 2003 SMG. If Year 5 does not meet performance success criteria, NCDMS may require additional monitoring until the site does meet all performance success criteria. Based on the design approaches and overall project goals, different monitoring methods are proposed for the project reaches. For reaches that involve Restoration and Enhancement Level I (stream bed/bank stabilization) approaches, geomorphic monitoring methods will follow those recommended by the 2003 SMG. For reaches involving Enhancement Level II approaches, monitoring efforts will focus primarily on visual inspections, photo documentation, and vegetation assessments. The monitoring parameters shall be consistent with the requirements described in the Federal Rule for compensatory mitigation sites in the Federal Register Title 33 Navigation and Navigable Waters Volume 3 Chapter 2 Section § 332.5 paragraphs (a) and (b). Specific success criteria components and evaluation methods are described below and report documentation will follow the NCDMS Baseline Monitoring Document template and guidance (v 2. 0, dated 10/14/10). MICHAEL BAKER ENGINEERING, INC. PAGE 4-1 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT -OPTION B (DMS PROJECT NO. 95026) 5.0 MONITORING PLAN AND SUCCESS CRITERIA 5.1 Stream Monitoring Geomorphic monitoring of the proposed restoration reaches will be conducted once a year for a minimum of five years following the completion of construction. These activities will evaluate the success criteria associated with a geomorphically stable channel, hydrologic connectivity, and aquatic habitat diversity. The stream parameters to be monitored include stream dimension (cross-sections), pattern (planimetric survey), profile (longitudinal profile survey), visual observation with photographic documentation, and documentation of bank full events. The success criteria for the proposed Enhancement Level II reaches/sections will follow the methods described in sections 5.1.7 and 5.2. The methods used and related success criteria are described below for each parameter. 5.1.1 Bankfull Events and Flooding Functions The occurrence of bankfull events within the monitoring period will be documented by the use of a crest gauge and photographs. The crest gauge will be installed on the floodplain within ten feet (horizontal) of the restored channel. The crest gauge will record the highest watermark between site visits, and the gauge 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 on the floodplain during monitoring site visits. Two bankfull flow events must be documented within a five-year monitoring period. The two bankfull events must occur in separate years; otherwise, the monitoring will continue until two bankfull events have been documented in separate years to demonstrate a floodplain connection has been restored. 5.1.2 Flow Documentation Monitoring of flow will be conducted to demonstrate that the restored stream systems classified as intermittent exhibit base flow for some portion of the year during a year with normal rainfall conditions. In order to determine if rainfall amounts are normal for the given year, rainfall gauge data will be obtained from the nearest Stanly County weather station (CRONOS Database, NEWL — North Stanly Middle School, if available) and compared to the average monthly rainfall amounts from the Stanly Count WETS Table (NRCS, 2002). If a normal year of precipitation does not occur during the first five years of monitoring, flow conditions will continue to be monitored on the site until it documents that the intermittent streams have been flowing during the appropriate times of the year. The proposed monitoring of the restored intermittent reaches will include a combination of photographic documentation and the installation of two in -stream pressure transducers within the thalweg (bottom) of the channel, one in the upstream portion of the reach and one in the downstream portion of the reach. A regular series of remote photos over time will be used to subjectively evaluate channel flow conditions throughout the year. More specifically, the longitudinal photos should indicate the presence of flow within the channel in order to discern water levels within the pools and riffles. The photographs will be taken from a height of approximately five to six feet to ensure that the same locations (and view directions) at the site are documented in each monitoring period and will be shown on a plan view map. The visual monitoring effort, including the photo locations with descriptions, will be included with NCDMS's annual monitoring reports. The devices will be inspected on a quarterly/semi-annual basis to document surface hydrology and provide a basis for evaluating general flow response to rainfall events and surface runoff during various water tables levels throughout the monitoring period. MICHAEL BAKER ENGINEERING, INC. PAGE 5-1 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) 5.1.3 Cross-sections Permanent cross-sections were installed at an approximate rate of one cross-section per 500 LF of restored stream, or nine (9) cross-sections located at riffles, and four (4) located at pools. Each cross- section was marked on both stream banks with permanent monuments using rebar in place to establish the exact transect used. A common benchmark was used for cross-sections and will be consistently used to facilitate easy comparison of year-to-year data. The cross-section surveys will occur annually and must include measurements of Bank Height Ratio (BHR) and Entrenchment Ratio (ER). The monitoring survey includes points measured at all breaks in slope, including top of stream banks, bankfull, inner berm, edge of water, and thalweg, if the features are present. Riffle cross-sections will be classified using the Rosgen Stream Classification System. There should be little change in as -built cross-sections. If changes do take place, they will be documented in the survey data and evaluated to determine if they represent a movement toward a more unstable condition (e.g., down -cutting or erosion) or a movement toward increased stability (e.g., settling, vegetative changes, deposition along the stream banks, or decrease in width/depth ratio). Using the Rosgen Stream Classification System, and all monitored cross-sections should fall within the quantitative parameters (i.e. BHR no more than 1.2 and ER no less than 2.2 for `C' stream types) defined for channels of the design stream type. Given the smaller channel sizes and meander geometry of the proposed steams, bank pins will not be installed unless monitoring results indicate active lateral erosion. Reference photo transects will be taken at each permanent cross-section. Lateral photos should not indicate excessive erosion or continuing degradation of the stream banks. Photographs will be taken of both stream banks at each cross-section. The survey tape will be centered in the photographs of the stream banks. The water line will be located in the lower edge of the frame, and as much of the stream bank as possible will be included in each photo. Photographers should make a consistent effort to maintain the same area in each photo over time. 5.1.4 Pattern The plan view measurements such as sinuosity, radius of curvature, meander width ratio will be taken on newly constructed meanders during baseline (Year 0) only. Subsequent visual monitoring will be conducted twice a year, at least five months apart, to document any changes or excessive lateral movement in the plan view of the restored channel. 5.1.5 Longitudinal Profile A longitudinal profile will be surveyed for the entire length of restored channel immediately after construction to document as -built baseline conditions for the first year of monitoring only. The survey will be tied to a permanent benchmark and measurements will include thalweg, water surface, bankfull, and top of low bank. Each of these measurements will be taken at the head of each feature (e.g., riffle, pool) and at the maximum pool depth. The longitudinal profile should show that the bedform features installed are consistent with intended design stream type. The longitudinal profiles will not be taken during subsequent monitoring years unless vertical channel instability has been documented or remedial actions/repairs are deemed necessary. 5.1.6 Bed Material Analysis After construction, there should be minimal change in the pebble count data over time given the current watershed conditions and sediment supply regime. Significant changes in particle sizes or size distribution in otherwise stable riffles and pools could warrant additional sediment transport analyses and calculations. A substrate sample will be collected annually at cross-sections where constructed riffles were installed as part of the project. One constructed riffle substrate sample will be compared to existing riffle substrate data collected during the design phase and any significant changes (i.e.; MICHAEL BAKER ENGINEERING, INC. PAGE 5-2 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) aggradation, degradation) will be noted after stream bank vegetation becomes established and a minimum of two bankfull flows or greater have been documented. 5.1.7 Visual Assessment Visual monitoring assessments of all stream sections will be conducted by qualified personnel twice per monitoring year with at least five months in between each site visit. Photographs will be used to document system performance and any areas of concern related to stream bank stability, condition of in -stream structures, channel migration, headcuts, live stake mortality, impacts from invasive plant species or animal species, and condition of pools and riffles. The photo locations and descriptions will be shown on a plan view map. The Photographs will be taken from a height of approximately five to six feet to ensure that the same locations (and view directions) at the site are documented in each monitoring period. A series of photos over time will be also be used to subjectively evaluate channel aggradation (bar formations) or degradation, stream bank erosion, successful maturation of riparian vegetation, and effectiveness of sedimentation and erosion control measures. 5.2 Vegetation Monitoring Successful restoration of the vegetation on a site is dependent upon hydrologic restoration, planting of preferred canopy species, and volunteer regeneration of the native plant community. In order to determine if the planting success criteria are achieved and riparian buffer establishment goals are met, vegetation monitoring will be conducted once a year for a minimum of five years following the completion of construction and one full growing season. These activities will evaluate the success criteria associated with the restoration and protection of the riparian buffer functions and corridor habitat, and reduction of sediment loading from floodplain erosion and nutrient loading through the uptake of riparian vegetation. In order to assess the success criteria of the riparian buffer effectively, vegetation -monitoring quadrants were installed and will be monitored across the restoration site in accordance with the CVS-NCDMS Protocol for Recording Vegetation, Version 4.0 (2006). The vegetation monitoring plots shall be a minimum of 2% of the planted portion of the site with a minimum of eight (8) plots established randomly within the planted riparian buffer areas per Monitoring Levels 1 and 2. No monitoring quadrants were established within areas where there are significant stands of undisturbed trees. The size of individual quadrants will be 100 square meters for woody tree species. Vegetation monitoring will occur in the fall, prior to the loss of leaves. Individual quadrant data will be provided and will include species diameter, height, density, and coverage quantities. Relative values will be calculated, and importance values will be determined. Individual seedlings will be marked such that they can be found in succeeding monitoring years. Mortality will be determined from the difference between the previous year's living, planted seedlings and the current year's living, planted seedlings. At the end of the first full growing season (from baseline/year 0) or after 180 days between March l" and November 30', species composition, stem density, and survival will be evaluated. For each subsequent year, until the final success criteria are achieved, the restored site will be evaluated March and November. The interim measure of vegetative success for the site will require the survival of at least 320, 3 -year old, planted trees per acre at the end of year three of the monitoring period. The final vegetative success criteria will be measured at year five and must consist of a density of no less than 260, 5 -year old, planted trees per acre. While measuring species density and height is the current accepted methodology for evaluating vegetation success on mitigation projects, species density and height alone may be inadequate for assessing plant community health. For this reason, the vegetation monitoring plan will incorporate the evaluation of additional plant community indices, native volunteer species, and the presence of invasive species vegetation to assess overall vegetative success. MICHAEL BAKER ENGINEERING, INC. PAGE 5-3 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) Baker will provide required remedial action on a case-by-case basis, such as: replanting more wet/drought tolerant species vegetation, conducting beaver management/dam removal, and removing undesirable/invasive species vegetation, and will continue to monitor vegetation performance until the corrective actions demonstrate that the site is trending towards or meeting the standard requirement. Existing mature woody vegetation will be visually monitored during annual site visits to document any mortality, due to construction activities or changes to the water table, that negatively impact existing forest cover or favorable buffer vegetation. 5.3 Wetland Monitoring Wetland mitigation has not been proposed for the site; therefore, no monitoring is included. 5.4 Stormwater Management Monitoring No stormwater BMPs are proposed for the site; therefore, no monitoring is included. MICHAEL BAKER ENGINEERING, INC. PAGE 5-4 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) 6.0 AS -BUILT DATA DOCUMENTATION Stream and vegetation components will be monitored for five years post -construction to evaluate project success. The specific locations of vegetation plots, flow/crest gauges, and cross-sections are shown on the as - built plan sheets. 6.1 Stream Data For monitoring stream success criteria, thirteen permanent cross-sections were installed along restored and enhanced reaches on the site of greater than 500 LF (Reach 2 — 3 and Reach 5). The permanent cross- sections will be used to monitor channel dimension and bank stability over time. One crest gauge was installed along the restored channels on Reach 5. The crest gauge will be used to document the occurrence of bankfull events. A longitudinal survey was completed for all restored and enhanced reaches to provide a baseline for evaluating changes in bed conditions over time. Pebble count data was collected for riffle cross-sections where constructed riffles were installed (X1, X4, X5, X7, X9, X10, and X12). The as -built permanent cross-sections (with photos), longitudinal data, and pebble count data, as well as the quantitative pre -construction, reference reach, and design data used to determine restoration approach are provided in Appendix B. As -built data will be used for comparison to post -construction monitoring data. The locations of the permanent cross-sections and the crest gauge are shown on the as -built plan sheets in Appendix D. Photographs of the selected portions of the restored reaches are provided in Appendix E. 6.2 Vegetation Data Bare -root trees and shrubs were planted within restoration and enhancement areas of the conservation easement. A minimum 50 -foot buffer was established and/or protected along both banks of all stream reaches. Planting of bare -root trees, shrubs and live stakes began in March 2016 and was completed on March 11, 2016. The Mitigation Plan for the Site specifies that the number of quadrants required shall be based on the CVS- NCDMS Protocol for Recording Vegetation, Version 4.0 (2006). The total number of quadrants was calculated using the CVS-NCDMS Entry Tool Database version 2.3.1. The sizes of individual quadrants are 100 square meters. A total of eight (8) vegetation plots were installed throughout the project Site. The initial planted density within each of the vegetation monitoring plots is provided in Table 8. The average density of planted bare root stems, based on the data from the eight vegetation monitoring plots, is 804 stems per acre. The location of each vegetation plot is shown on the as -built plan sheets in Appendix D. 6.3 Areas of Concern Per observations made during the NCDMS Site visit on February 2, 2016, invasive species such as parrotfeather (Myiophyllum aquaticum) and Chinese privet (Ligustrum sinese), which are prevalent in areas outside of the conservation easement, may try to reestablish within the easement if not properly maintained. No other areas of concern were noted for the time of this report. Section 7.3 describes a specific corrective action plan that will be implemented for areas of concern. MICHAEL BAKER ENGINEERING, INC. PAGE 6-1 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) 7.0 MAINTENANCE AND CONTINGENCY PLANS Maintenance requirements vary from site to site and are generally driven by the following conditions: Projects without established, woody floodplain vegetation are more susceptible to erosion from floods than those with a mature, hardwood forest. Projects with sandy, non -cohesive soils are more prone to bank erosion than cohesive soils or soils with high gravel and cobble content. Alluvial valley channels with access to their floodplain are less vulnerable to erosion than channels that have been disconnected from their floodplain. Wet weather during construction can make accurate channel and floodplain excavations difficult. Extreme and/or frequent flooding can cause floodplain and channel erosion. Extreme hot, cold, wet, or dry weather during and after construction can limit vegetation growth, particularly temporary and permanent seed. The presence and aggressiveness of invasive vegetation species can affect the extent to which a native species vegetation buffer can be established. The presence of beaver can affect vegetation survivability and stream function. The Site will be monitored on a regular basis and as well as a physical inspection of the Site at least once a year throughout the post -construction monitoring period. These site inspections may identify site components and features that require routine maintenance. Maintenance issues and recommended remediation measures will be detailed and documented in the post -construction monitoring reports. Factors that may have caused any maintenance needs, including any of the conditions listed above, shall be discussed. Routine maintenance will be most likely in the first two years following site construction and may include the following components as described below. 7.1 Streams Routine channel maintenance and repair activities may include modifying in -stream structures to prevent piping, securing loose coir matting, and supplemental installations of live stakes and other target vegetation along the project reaches. Areas of concentrated stormwater and floodplain flows that intercept the channel may also require maintenance to prevent bank failures and head -cutting until vegetation becomes established. 7.2 Wetland No wetland mitigation was proposed for the Site; therefore, no such maintenance is required. 7.3 Vegetation Vegetation will be maintained to ensure the health and vigor of the targeted plant community. Routine vegetation maintenance and repair activities may include supplemental planting, pruning, and fertilizing. Exotic invasive plant species will controlled by mechanical and/or chemical methods. Any invasive plant species control requiring herbicide application will be performed in accordance with NC Department of Agriculture (NCDA) rules and regulations. MICHAEL BAKER ENGINEERING, INC. PAGE 7-1 11/15/2016 FINAL BASELINE MONITORING REPORT TOWN CREEK RESTORATION PROJECT - OPTION B (DMS PROJECT NO. 95026) The vegetation plantings will be documented in the Year 1 Monitoring Report and areas of concern will be observed closely during subsequent monitoring periods to determine if further corrective action is required to meet the interim vegetative success criteria of 260 stems per acre at the end of five years. 7.4 Site Boundary Site boundaries have been demarcated in the field to ensure clear distinction between the mitigation site and adjacent properties. Boundaries are identified by fence, marker, bollard, post, or other means as allowed by site conditions and/or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as needed basis. 7.5 Farm Road Crossing The farm road crossings within the Site may be maintained only as allowed by the recorded Conservation Easement, deed restrictions, rights of way, or corridor agreements. 7.6 Beaver Management Routine maintenance and repair activities caused by beaver activity may include supplemental planting, pruning, and dam breeching/dewatering and/or removal. Beaver management will be performed in accordance with US Department of Agriculture (USDA) rules and regulations using accepted trapping and removal techniques only within the project boundary.
