(Wildlands) completed a full -delivery project for the North Carolina Division of Mitigation Services (DMS) to restore a total of 4,968 linear feet (LF) of stream and restore, enhance, and create 17.2 acres (ac) of wetlands in Rockingham County, North Carolina. The project streams consist of Little Troublesome Creek, Irvin Creek and one unnamed tributary (UT1) to Little Troublesome Creek. The largest of these streams, Little Troublesome Creek, ultimately drains to the Haw River. At the downstream limits of the project, the drainage area is 3,245 acres (5.1 square miles). The Little Troublesome Creek Stream Mitigation Site, hereafter referred to as the Stream Site, is located in Rockingham County on the southeastern side of Reidsville along Irvin and Little Troublesome Creeks. The wetland area, hereafter referred to as the Wetland Site, is located approximately four miles southeast of the Stream Site and is also adjacent to Little Troublesome Creek. The Stream Site is located south of Turner Road, east of the intersection of Turner Road and Way Street in the City of Reidsville, North Carolina (Figure 1). The Wetland Site is located approximately 3,000 feet southwest of the intersection of NC Highway 150 and Mizpah Church Road, south of the City of Reidsville (Figure 1). The Stream and Wetland Sites are located in the Inner Piedmont Belt of the Piedmont Physiographic Province (USGS, 1998). The Sites are located within the North Carolina Division of Water Resources (NCDWR) subbasin 03-06-01 of the Cape Fear River Basin, United States Geological Survey (USGS) Hydrologic Unit 03030002010030. Approximately 28% of the land in the project watershed has been developed and approximately 17% of the land surface is impervious. Land uses within the watershed include: forested land (55%), developed (28%), and cultivated land (17%). The Stream Site is a tract owned by Wildlands Little Troublesome Creek Holdings, LLC and the Wetland Site is owned by Jerry Apple. Prior to construction activities, the most significant watershed stressors identified during the technical assessment were stream bank erosion and instability. Other stressors included declining aquatic habitat, loss of forest, degraded riparian buffers, loss of wetlands, lack of urban stormwater detention, and water quality problems related to increased sediment and nutrient loadings. As a result of the aforementioned stressors, the Stream Site and Wetland Site had poor water quality due to sediment pollution and poor habitat due to lack of riparian and wetland vegetation. In particular, the Stream Site lacked stable streambank vegetation despite being surrounded by mature vegetation. The Stream Site also lacked in - stream bed diversity and exhibited unstable geomorphic conditions. The primary objectives of the project were to stabilize highly eroding stream banks, reconnect streams to their historic floodplain, improve wetland hydrology and function, reduce nutrient levels, sediment input, and water temperature, increase dissolved oxygen concentrations, create appropriate in -stream and terrestrial habitat, and decrease channel velocities. These objectives were achieved by restoring 4,968 LF of perennial stream channel, and restoring, enhancing, and creating 17.2 acres of riparian wetland. The Stream Site and Wetland Site riparian areas were also planted to stabilize streambanks, improve habitat, and protect water quality. Figure 2 and Table 1 in Appendix 1 present design applications for the Sites. The following project goals were established to address the effects listed above from watershed and project site stressors: • Stabilize stream dimensions; • Stabilize stream pattern and profile; • Establish proper substrate distribution throughout the streams; • Establish wetland hydrology for restored wetlands; and • Restore native vegetation throughout wetlands and buffer zones. Little Troublesome Creek Mitigation Site Monitoring Year 5 Annual Report— FINAL iii The following secondary project goals (unmeasured) were established in the project Mitigation Plan (Wildlands, 2011) to address the effects from watershed and project site stressors: • Decrease nutrient and urban runoff pollutant levels; • Decrease sediment input; • Decrease water temperature and increase dissolved oxygen levels; • Create appropriate in -stream habitat; • Create appropriate terrestrial habitat; and • Decrease channel velocities. Stream and wetland restoration, enhancement, and creation construction efforts were completed in May 2012. A conservation easement is in place on 33.0 ac (acres) of the Stream Site and 19.0 ac of the Wetland Site to protect them in perpetuity. Monitoring Year 5 (MY -5) monitoring and site visits were completed during April -November, 2016 to assess the conditions of the Sites. Overall, the Sites have met the required hydrologic, vegetation, and stream success criteria for MY -5. The Sites overall average stem density of 571 stems/ acre is greater than the 260 stem/ acre density required at MY -5. Except for a few isolated bank erosion areas, the restored and enhanced streams are stable and functioning as designed and the Stream Site has met the Monitoring Year 5 (MY -5) hydrology success criteria. All groundwater gages met the MY -5 success criteria on the Wetland Site.

The Little Troublesome Creek Stream Mitigation Site, hereafter referred to as the Stream Site, is located in Rockingham County on the southeastern side of Reidsville along Irvin and Little Troublesome Creeks. The wetland area, hereafter referred to as the Wetland Site, is located approximately four miles southeast of the Stream Site and is also adjacent to Little Troublesome Creek. The Stream Site is located south of Turner Road, east of the intersection of Turner Road and Way Street in the City of Reidsville, North Carolina (Figure 1). The Wetland Site is located approximately 3,000 feet southwest of the intersection of NC Highway 150 and Mizpah Church Road, south of the City of Reidsville (Figure 1). The Sites are located in the Inner Piedmont Belt of the Piedmont Physiographic Province (USGS, 1998). The project watersheds consists of forested, developed, and cultivated lands. The drainage area for the Stream Site is 3,245 acres at the lower end of Little Troublesome Creek. The project stream reaches consist of Little Troublesome Creek, Irvin Creek, and one unnamed tributary (UT1) to Little Troublesome Creek (stream restoration approach). Mitigation work within the Sites included restoring 4,968 linear feet (LF) of perennial and intermittent stream channel and restoring, enhancing, and creating 17.2 acres (ac) of riparian wetland. The Stream and Wetland Sites were also planted with native vegetation to improve habitat and protect water quality. Conservation easements have been recorded on the Sites and are in place along the stream and wetland riparian corridors to protect them in perpetuity; 33.0 ac (Deed Book 1411, Page Number 2458) owned by Wildlands Little Troublesome Creek Holdings, LLC and 19.0 ac (Deed Book 1412, Page Number 1685) owned by Jerry Apple. Directions and maps of the Sites are provided in Figure 1 and project components are illustrated for the Sites in Figures 2a and 2b. The final Mitigation Plan was submitted and accepted by the North Carolina Division on Mitigation Services (DMS) in June of 2011. Construction activities were completed by Fluvial Solutions in May of 2012. Planting and seeding activities were completed by Bruton Natural Systems, Inc. in May 2012. Baseline monitoring (MY -0) was conducted between April and May 2012. MY -5 monitoring and site visits were completed during April -November, 2016 to assess the condition of the Sites. Close-out of the Stream and Wetland Sites are proposed for 2017. Appendix 1 provides more detailed project activity, history, contact information, and watershed/site background information for this project. 1.1 Project Goals and Objectives Prior to construction activities, the most significant watershed stressors identified during the technical assessment were stream bank erosion and instability. Other stressors included declining aquatic habitat, loss of forest, degraded riparian buffers, loss of wetlands, lack of urban stormwater detention, and water quality problems related to increased sediment and nutrient loadings. As a result of the aforementioned stressors, the Stream Site and Wetland Site had poor water quality due to sediment pollution and poor habitat due to lack of riparian and wetland vegetation. In particular, the Stream Site lacked stable streambank vegetation despite being surrounded by mature vegetation. The Stream Site also lacked in - stream bed diversity and exhibited unstable geomorphic conditions. Table 4 in Appendix 1 and Tables 10a, and 10b in Appendix 4 present the pre -restoration conditions in detail. The Sites were designed to meet the over -arching goals as described in the Mitigation Plan (Wildlands, 2011) to address the effects from watershed and project site stressors. The project is intended to provide Little Troublesome Creek Mitigation Site Monitoring Year 5 Annual Report— FINAL 1-1 numerous ecological benefits within the Cape Fear River Basin. While many of these benefits are limited to the Sites project area, others, such as pollutant removal and improved aquatic and terrestrial habitat, have more far-reaching effects. The following project specific primary goals established in the Mitigation Plan include: • Stabilize stream dimensions; • Stabilize stream pattern and profile; • Establish proper substrate distribution throughout the streams; • Establish wetland hydrology for restored wetlands; and • Restore native vegetation throughout wetlands and buffer zones. Secondary project goals (unmeasured) established in the Mitigation Plan were to address the effects from watershed and project site stressors include: • Decrease nutrient and urban runoff pollutant levels; • Decrease sediment input; • Decrease water temperature and increase dissolved oxygen levels; • Create appropriate in -stream habitat; • Create appropriate terrestrial habitat; and • Decrease channel velocities. The primary and secondary project goals were addressed through the following project objectives: • Riffle cross sections of the restoration and enhancement reaches were constructed to remain stable and will show little change in bankfull area, maximum depth ratio, and width -to -depth ratio over time. • The project was constructed so that the bedform features of the restoration reaches will remain stable overtime. This includes riffles that will remain steeper and shallower than the pools, and pools that are deep with flat water surface slopes. The relative percentage of riffles and pools will not change significantly over time. Banks were constructed so that bank height ratios will remain very near to 1.0 for nearly all of the restoration reaches. • Stream substrate will remain coarse in the riffles and finer in the pools. • A free groundwater surface will be present within 12 inches of the ground surface in the restored wetland areas for 7 percent of the growing season measured on consecutive days under typical precipitation conditions. • Native vegetation appropriate for the wetland and riparian buffer zones were planted throughout both the Wetland and Stream Sites. The planted trees will become well established and survival success criteria will be met. • Off-site nutrient input will be absorbed on-site by filtering flood flows through restored floodplain areas and wetlands, where flood flows can disperse through native vegetation and be captured in vernal pools. Increased surface water residency time will provide contact treatment time and groundwater recharge potential. • Sediment input from eroding stream banks was reduced by installing bioengineering and in - stream structures while creating a stable channel form using geomorphic design principles. Sediment from off-site sources will be captured by deposition on restored floodplain areas where native vegetation will slow overland flow velocities. • Restored riffle/pool sequences where distinct points of re -aeration can occur will allow for oxygen levels to be maintained in the perennial reaches. Creation of deep pool zones will lower water temperature, helping to maintain dissolved oxygen concentrations. Little Troublesome Creek Mitigation Site Monitoring Year 5 Annual Report— FINAL 1-2 Establishment and maintenance of riparian buffers will create long-term shading of the channel flow to minimize thermal heating. • A channel form that includes riffle/pool sequences and gravel and cobble zones creating habitat for macroinvertebrates and fish. Large woody debris, rock structures, root wads, and native stream bank vegetation were introduced to substantially increase habitat value. • Adjacent buffer areas were restored by removing invasive vegetation and planting native vegetation. These areas will be allowed to receive more regular and inundating flows. Riparian wetland areas were restored and enhanced to provide wetland habitat. By allowing for more overbank flooding and by increasing channel roughness, local channel velocities can be reduced. This will allow for less bank shear stress, formation of refuge zones during large storm events and zonal sorting of depositional material. The design streams and wetlands were restored to the appropriate type based on the surrounding landscape, climate, and natural vegetation communities but also with strong consideration to existing watershed conditions and trajectory. The mitigation project was developed to restore a high quality of riparian function to the streams, wetlands, and riparian corridors. 1.2 Monitoring Year 5 Data Assessment Annual monitoring and quarterly site visits were conducted during Monitoring Year 5 (MY -5) to assess the condition of the project. The stream and wetland mitigation success criteria for the Sites follow the approved success criteria presented in the Mitigation Plan (Wildlands, 2011). 1.2.1 Vegetative Assessment A total of 35 (13 at the Stream Site; 22 at the Wetland Site) vegetation plots were established within the project easement areas using standard 10 meter by 10 meter vegetation monitoring plots. UT1 was constructed within a narrow cleared corridor to minimize disturbance to the surrounding mature vegetation. Due to the narrow planted corridor along UTI, vegetation plots were not established. Instead, a visual assessment of the planted corridor is used to evaluate vegetation growth success. The final vegetative success criteria is the survival of 260 planted stems per acre in the riparian corridor at the end of MY -5. The MY -5 vegetative survey was completed in June 2016. The 2016 annual vegetation monitoring resulted in an average stem density of 635 stems per acre for the Stream Site, which is greater than the final requirement of 260 stems/acre and approximately 33% less than the baseline (MY -0) density recorded (953 stems/acre). There was an average of 16 stems per plot in MY -5 compared to 24 stems per plot in MY -0 for the Stream Site. All 13 plots at the Stream Site meet the MY -5 success criteria of 260 planted stems per acre. At the Wetland Site, three of the plots did not meet the final success criteria and averaged 189 stems per acre; however with the inclusion of volunteer species the three plots average 499 stems per acre which is well above the final requirement of 260 stems/acre. These three plots are located on one of the wettest parts of the Wetland Site. In the past, Wildlands has observed higher planted tree mortality in areas with frequently standing water, compared to the drier parts of projects. There was an average of 12 stems per plot in MY -5 as compared to 17 stems per plot during MY -0 for the Wetland Site. Although three wetland vegetation plots are not meeting for planted stems, the volunteer stems consist of desirable hardwood species from the planting plan. With the inclusion of volunteer species, all 22 plots at the Wetland Site meet the MY -5 success criteria. Refer to Appendix 2 for vegetation plot photographs, the vegetation condition assessment table, and the Current Condition Plan View Map, and Appendix 3 for vegetation data tables. Little Troublesome Creek Mitigation Site Monitoring Year 5 Annual Report— FINAL 1-3 1.2.2 Vegetation Areas of Concern Vegetative areas of concern noted during the annual visual assessments included isolated areas of non- native invasive species at the Stream Site. An invasive species management and control plan was initially initiated in MY3 and has continued annually during the monitoring period. Invasive species management has included foliar herbicidal applications. Maintenance Plan Visual assessments will be performed in 2017 prior to project close-out to determine if any additional maintenance is necessary to control invasive species within the Site. 1.2.3 Stream Assessment Morphological surveys for the MY -5 were conducted in April 2016. With the exception of a few isolated areas of bank scour, all streams within the Stream Site are stable with little to no erosion and have met the success criteria for MY -5. Refer to Appendix 2 for the visual assessment table, the Integrated Current Condition Plan View Map, and reference photographs. Refer to Appendix 4 for the morphological data and plots. In general, cross sections show little to no change in the bankfull area, maximum depth ratio, or width -to - depth ratio. Cross Sections on UT1 show a decrease in cross-sectional area and bankfull width. This is due to sediment deposition from Little Troublesome Creek during bankfull events. This is normal and is not a sign of instability. Surveyed riffle cross sections fell within the parameters defined for channels of the appropriate Rosgen stream type. Several pool cross sections on the Stream Site have shown an accumulation of sediment on the point bars resulting in a slight narrowing of the pool cross sections. Since point bars are depositional features, this is fully expected. As discussed in the Mitigation Plan, narrowing of the channel over time is expected for restored alluvial streams and is an indication of stability. The surveyed longitudinal profile data for the stream restoration reaches illustrates that the bedform features are maintaining lateral and vertical stability. The riffles are remaining steeper and shallower than the pools, while the pools are remaining deeper than riffles and maintaining flat water surface slopes. The longitudinal profiles show that the bank height ratios remain near 1.0 for all of the restoration reaches. UT1 longitudinal profile data is showing deposition throughout the stream. This sediment deposition appears to be from bankfull events on Little Troublesome Creek. This is normal and expected on small streams that flow into large channels and is not affecting channel stability. In -stream structures such as root wads, used to enhance channel habitat and stability on the outside bank of meander bends are providing stability and habitat as designed. During MY -5 a few isolated areas of bank scour were documented on Little Troublesome Creek and Irvin Creek. These areas will be repaired during the winter of 2016/ 2017 as described below in section 1.2.4. During MY -4 bank scour was documented in part of the meander bend at STA 207+50-208+80 on Little Troublesome Creek. Undercutting of the rootwads resulted in an area of bank scour within this meander bend. This was repaired at the beginning of MY -5 by lowering the rootwads and adding brush toe to fill in any voids. Geolifts were installed with brush whips and live stakes to stabilize the stream bank. Since the repair work, this section of Little Troublesome Creek appears stable and will continue to be monitored for any signs of instability. No changes were observed that indicated a change in the radius of curvature or channel belt width; therefore, pattern data is not included in the MY -5 report. Little Troublesome Creek Mitigation Site Monitoring Year 5 Annual Report— FINAL 1-4 1.2.4 Stream Areas of Concern The Stream Site had a significant flow event during Hurricane Mathew, resulting in a few isolated areas of bank scour on Little Troublesome Creek and Irvin Creek. Wildlands is currently working with a contractor to repair these areas prior to project close-out. This repair will include installing brush toe and soil lifts with live willow whips. Most of the repair work will be done by hand and will include planting live stakes on the stream banks. Heavy equipment will only be used when necessary to avoid causing any damage to the Site. The only area that will require heavy equipment is one bend on Little Troublesome Creek. Refer to Appendix 2, Current Condition Plan View Maps for the location of bank scour on these streams. 1.2.5 Hydrology Assessment At the end of the five year monitoring period, two or more bankfull events must have occurred in separate years within the restoration reaches. Bankfull events were recorded on Irvin Creek, Little Troublesome Creek, and UT1 by crest gage or onsite observations (wrack lines) during all five monitoring years, with multiple events occurring during some of these years. The Stream Site has therefor met the hydrologic success criteria. Please refer to Appendix 5 for hydrologic data. Trail cameras were established on Little Troublesome and Irvin Creeks to capture hourly pictures during MY -5. Appendix 5 shows a few of the pictures collected with the trail camera during bankfull events. 1.2.6 Wetland Assessment Eight groundwater monitoring gages are established in the wetland restoration, enhancement, and creation zones. The gages were installed at appropriate locations so that the data collected will provide an indication of groundwater levels throughout the Wetland Site. A barotroll logger and a rain gage were also installed onsite. To provide data for the determination of the growing season for the wetland areas, two soil temperature probes were installed to collect growing season data. These probes are used to better define the beginning of the growing season using the threshold soil temperature of 41 degrees or higher measured at a depth of 12 inches (USACE, 2010). During MY -1, MY -2, and MY -3 NRCS WETS Data was used to determine the growing season for the Wetland Site. After discussions with the United States Army Corps of Engineers (USACE), it was agreed to use on-site soil temperature data to determine the beginning of the growing season and use NRCS WETS data to determine the end of the growing season. During MY -5, the beginning of the growing season was extended by 15 days based on data from the soil temperature probes. All monitoring gages were downloaded on a quarterly basis and maintained on an as needed basis. The success criteria for wetland hydrology is to have a free groundwater surface within 12 inches of the ground surface for 7 percent of the growing season, which is measured on consecutive days under typical precipitation conditions. All groundwater gages met the annual wetland hydrology success criteria for MY -5. Refer to Appendix 2 for the groundwater gage locations and Appendix 5 for groundwater hydrology data and plots. 1.2.7 Maintenance Plan Wildlands is currently working with a contractor to repair the isolated area of bank erosion as described in section 1.2.4 above. 1.3 Monitoring Year 5 Summary With the exception of pool deposition on UT1 and a few isolated areas of bank scour, all streams within the Stream Site are stable and functioning as designed. Repair work is being coordinated on Little Troublesome Creek and will be implemented this winter. The overall, average stem density for the Sites Little Troublesome Creek Mitigation Site Monitoring Year 5 Annual Report— FINAL 1-5 meets the MY -5 success criteria; however, three individual vegetation plots did not meet the MY -5 success criteria as noted in the Integrated Current Condition Plan View Map. These three vegetation plots do meet the MY -5 success criteria when volunteer trees were included in the totals. While the stream hydrology success criteria was met during the initial two years of monitoring, additional bankfull events were documented in MY -5. All groundwater gages met the MY -5 success criteria. Summary information and data related to the performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Little Troublesome Creek Mitigation Site Monitoring Year 5 Annual Report— FINAL 1-6 Section 2: METHODOLOGY Geomorphic data was collected following the standards outlined in The Stream Channel Reference Site: An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in the Stream Restoration: A Natural Channel Design Handbook (Doll et al., 2003). Cross section data was collected using a total station and was georeferenced. All data collected for the Integrated Current Condition Mapping was recorded using a Trimble handheld GPS with sub -meter accuracy and processed using Pathfinder and ArcView. Crest gages were installed in surveyed riffle cross sections and monitored quarterly. Hydrology attainment installation and monitoring methods are in accordance with the USACE (USACE, 2003) standards. Vegetation monitoring protocols followed the Carolina Vegetation Survey-NCDMS Level 2 Protocol (Lee et al., 2008). Reporting follows the NCDMS Monitoring Report Template and Guidance Version 1.2.1 (NCDMS, 2009). Narrative background and supporting information formerly found in these reports can be found in the Mitigation Plan documents available on DMS's website. All raw data supporting the tables and figures in the appendices are available from DMS upon request.

Stream credits were also calculated using the 2003 Stream Mitigation Guidlines instead of using the INC IRT Draft Regulatory Guidance for the Calculation of Stream and Buffer Mitigation Credit (March 11, 2009). **The higher enhancement ratio was agreed to with Todd Tugwell, with the USAGE, during a March 9, 2011 meeting for several reasons. The higher ratio is warranted because of the low quality of the existing wetland enhancement zone. Previously the enhancement zone, like the restoration and creation zones, was used for farming. The hydrology of the site has been altered by a drainage ditch and a berm along Little Troublesome Creek. There is no vegetation on the site except for some areas of grasses and cultivated crops. Enhancement activities performed on the site will include improving the hydrology of the enhancement zone (as well as the creation and restoration zones) and restoring the native vegetation. Therefore the functional uplift of the enhancement portion of the project will be nearly the same as that of the restoration zone and, thus, a high ratio for enhancement is appropriate. Table 2.
