As per the approved Mitigation Plan for the Site, this Annual Monitoring Report presents stream geometry data, stem count data from vegetation monitoring stations, and discusses any observed tendencies relating to stream stability and vegetation survival success. Prior land use on the Site consisted primarily of pasture and forest. Candiff Creek had been channelized and riparian vegetation was cleared in the lower half of the site. The upstream reaches of the project had a narrow, early successional buffer that included several exotic vegetation species. Prior to restoration, Candiff Creek was incised and lacked bedform diversity. As a result, channel degradation was widespread throughout the Site. A total of 13 monitoring plots, 100 square meters (m2) (10m x 10m) in size, are used to predict survivability of the woody vegetation planted on the Site. Data from Year 4 monitoring for the 13 vegetation plots exhibited a survivability range of 40 to 931 stems per acre. The data showed that the Site had an average survivability of 735 stems per acre following Year 4 monitoring. During Year 4 monitoring, kudzu (Pueraria montana) was present on the Site in the vicinity of vegetation plot 13 and in the general vicinity. This concentration of kudzu was previously treated during construction and remnants are still present within the easement. The kudzu is located on the upstream portion of Reach M1, downstream of River-Siloam Road. This area was treated once in early August 2015 and once in late August 2015 by use of the herbicides Glyphosate and Triclopyr. Any remaining kudzu in this area will be treated again during the early growing season 2016. Vegetation Plots 1 through 12 on reach M2 and M3 did not exhibit any invasive or aggressive species occurring on the Site. Also, additional stream enhancement work along M1 and UT1 was completed in September 2015. Bankfull benches were excavated and vertical stream banks were sloped to stable angles. In addition, vane structures and toe wood were installed along meander bends to protect the stream banks, provide additional habitat, and to provide long-term stream bank stabilization. No additional credit is being requested as a result of this work. During this time, the existing kudzu plants and roots were cleared within a large portion of the easement area. Per the permit conditions for the enhancement work, monitoring along M1 and UT1 will be conducted for a minimum of one additional year beyond the monitoring required in the mitigation plan. This monitoring will include visual assessments conducted twice per year and the installation and annual monitoring of two bank pin arrays installed in the outside of meander bends. Property boundary fencing in the M1 vicinity was installed during the summer of 2015. This fence allows the landowner to graze cattle outside of the fenced conservation easement which will prevent kudzu re-establishment. Additional bare-root trees will be planted during the winter of 2015 in the riparian buffer areas along M1 and UT1 to increase density and to offset mortality from treating kudzu. Cross-sectional monitoring data for stream stability were collected during Year 4 monitoring. A longitudinal profile survey was completed during Year 4 monitoring for approximately 3,542 linear feet (LF) of stream on the Site. The longitudinal profile was completed for Reach M3 only. Candiff Creek Restoration Project, DMS Project No. 92767 November 2015, Monitoring Year 4 FINAL 2 The cross-sectional data and the longitudinal profile indicate that Reach M3 is stable and functioning as designed. Two pools located at stations 46+50 and 55+50 have exhibited areas of erosion during Year 4 monitoring. The erosional areas observed are occurring on the outer bend below the root wads and are approximately 10 feet or less in length. According to the on-site crest gauge, the Site experienced at least two significant bankfull flow events during Year 4 monitoring. The largest on-site bankfull flow event documented at the M3 crest gauge occurred on April 20, 2015. It is estimated that the height of highest flow at the M3 crest gauge observed in Year 4 was approximately 2.85 feet above bankfull stage. In summary, after remedial activities planned in winter 2015 and summer 2016, to control kudzu and improve tree density along M1, the Site is on track to meet the hydrologic, vegetative, and stream success criteria as specified in the Site Restoration Plan in all areas. Candiff Creek Restoration Project, DMS Project No. 92767 November 2015, Monitoring Year 4 FINAL 3 2.0 PROJECT BACKGROUND The project involved the restoration of 4,081 linear feet (LF) of stream, 1,757 of stream Enhancement (265 LF of Enhancement I and 1,492 LF of Enhancement II) and 1,200 LF of stream preservation. The final stream lengths for all reaches are shown in Table 1 and Figure 2 and summarizes the restoration zones on the Site. A total of 27.54 acres of stream and riparian buffer are protected through a permanent conservation easement. 2.1 Project Objectives The specific goals for the Candiff Creek Restoration Project were as follows:  Create geomorphically stable conditions along Candiff Creek through the project area  Prevent cattle from accessing the project reaches, reducing excessive bank erosion,  Improve habitat quality in a riffle dominated stream by adding pool/riffle sequences and expanding the floodplain, while improving overall ecosystem functionality  Improve water quality within the Candiff Creek Restoration Project area through reduction of bank erosion and reductions in nutrient and sediment loads  Stabilize streambanks through installation of in-stream structures and establishing a riparian buffer consisting of native plant species  Improve aquatic and terrestrial habitat through increased substrate and in-stream cover, additional woody debris, and reduced water temperature by increasing stream shading, and restored terrestrial habitat. 2.2 Project Structure, Restoration Type and Approach For analysis and design purposes, Michael Baker International (Baker) divided on-site streams into reaches. The reaches were numbered sequentially from upstream to downstream, with a “M” designation for the “mainstem” and a “UT” designation for unnamed tributaries. Two UTs are located on the Site (labeled UT1 and UT2). The on-site streams are described as follows: M1 begins on the upstream section of the Site at the River-Siloam Road culvert, and then flows southward to the confluence with UT2. M2 begins at the M1/UT2 confluence and flows south 265 feet to the beginning of the restored portion of the mainstem. M3 begins at the restored channel and then flows southeastward for 4,123 feet and terminates at the property line adjacent to the Yakin Valley Railroad right-of-way located at the downstream end of the Site. UT1 flows onto the Site from the southern Wall property line and flows southward for 885 feet to the confluence with M1. UT2 flows onto the Site from the eastern Aztar Group, LLC property line and flows eastward for 1,162 feet and terminates at the M1/M2 transition. The reaches described above are presented in the plan sheets located in Figures 3A through Figure 3J. The restoration design allows stream flows greater than the bankfull discharge, to spread onto the floodplain, dissipating flow energies and reducing stress on streambanks. In-stream structures were used to control streambed grade, reduce streambank stress, and promote bedform sequences and habitat diversity. The in-stream structures installed consist of constructed riffles, cover logs, log/rock vanes, log/rock j-hook vanes, rock cross vanes, vegetated geolifts, vegetated brush mattresses and root wads. These structures promote a diversity of habitat features in the restored channel. Where grade control was a consideration, constructed riffles, grade control rock j-hook vanes, and rock cross vanes were installed to provide long-term stability. Streambanks were stabilized using a combination of Candiff Creek Restoration Project, DMS Project No. 92767 November 2015, Monitoring Year 4 FINAL 4 erosion control matting, temporary and permanent seeding, live stakes, transplants, brush mattresses and geolifts. Transplants provide areas for living root mass to increase streambank stability and also to create holding areas for fish and aquatic biota. The purpose of the project is to restore stream functions to the impaired reaches the Site. Native species vegetation was planted across the Site and the entire project area is protected through a permanent conservation easement.

The Site lies in the Yadkin Pee-Dee River Basin, within the US Geological Survey (USGS) and North Carolina Department of Environmental Quality Division of Mitigation Services (NCDEQ DMS) subbasin 03040101 (previously categorized as subbasin 03-07-02) and Targeted Local Watershed (TLW) 03040101-110060 of the Yadkin Pee Dee River Basin. 2.4 Project History and Background Land use at the Site consists primarily of pasture and forest. Candiff Creek had been channelized and riparian vegetation had been cleared at the lower half of the Site. The upstream end of the Site had a narrow, early successional buffer that included several exotic vegetation species. Prior to restoration, Candiff Creek was incised and lacked bedform diversity. As a result, channel degradation was widespread throughout the Site. The chronology of the Candiff Creek Restoration Project is presented in Table 2. The contact information for the designers, contractors, and relevant suppliers is presented in Table 3. Relevant project background information is provided in Table 4. 2.5 Project Plan Plans illustrating the as-built conditions of the major project elements, locations of permanent monitoring cross-sections, and locations of permanent vegetation monitoring plots are presented in Figures 3A through 3G of this report.

The woody vegetation was planted randomly from the top of the stream banks to the outer edge of the project’s re-vegetation limits. In general, bare- root vegetation was planted at a target density of 680 stems per acre, in an 8-foot by 8-foot grid pattern. Live stakes were installed two to three feet apart in meander bends and six to eight feet apart in the riffle cross-sections. The live stakes were set up using triangular spacing along the stream banks between the toe of the stream bank and bankfull elevation. The tree species planted at the Site are shown in Table 5. The temporary seed planted following construction was rye grain. The permanent seed mix of herbaceous species planted in the project’s riparian area included: redtop (Agrostis alba), big bluestem (Andropogon gerardii), beggartick (Bidens frondosa), lanceleaf tickseed (Coreopsis lanceolata), deertongue (Pancium clandestinum), Virginia wildrye (Elymus virginicus), soft rush (Juncus effusus), switchgrass (Panicum virgatum), smartweed (Polygonum pennsylvanicum), little bluestem (Schizachyrium scoparium), Indian grass (Sorghastrum nutan), and eastern gamma grass (Tripsacum dactyloides). This seed mixture was broadcast on the Site at a rate of 15 pounds per acre. All planting was completed in April 2012. At the time of planting, 13 vegetation plots – labeled 1 through 13 - were established on-site to monitor survival of the planted woody vegetation. Each vegetation plot is 0.025 acre in size, or 10 meters x 10 meters. All of the planted stems inside the plots were flagged to distinguish them from any colonizing individuals and to facilitate locating them in the future. The trees also were marked and labeled with aluminum metal tags to ensure that the correct identification is made during future monitoring of the vegetation plots. In addition to flagging and tags, the locations of planted stems and vegetation plot corners were recorded by use of survey equipment. 3.1.2 Vegetative Success Criteria To characterize vegetation success criteria objectively, specific goals for woody vegetation density have been defined. Data from vegetation monitoring plots should display a surviving tree density of at least 320 trees per acre at the end of the third year of monitoring, and a surviving tree density of at least 260 five-year-old trees per acre at the end of the five-year monitoring period.

Tables A.1 through A.6 in Appendix A presents vegetation metadata, vegetation vigor, vegetation damage and stem count data for the monitoring plots at the end of Year 4 monitoring. Data from Year 4 monitoring for the 13 vegetation plots exhibited a range of 40 to 931 stems per acre. The data show that the Site had an average survivability of 735 stems per acre following Year 4 monitoring. In comparison, following as-built conditions, the Site demonstrated an average survivability of 915 stems per acre. Trees within each monitoring plot are re-flagged regularly to prevent planted trees from losing their identifying marks due to flag degradation. It is important for trees within the monitoring plots to remain marked to ensure they are all accounted for during the annual stem counts and calculation of tree survivability. Labeled aluminum tags with wire hangers are used on surviving stems to aid in relocation during future counts. The aluminum tags are moved to a single branch instead of the main stem once the tree becomes established. Flags are also used to mark trees because they do not interfere with the growth of the tree. During Year 4 monitoring, volunteer species including tulip poplar (Liriodendron tulipfera) and redbud (Cercus canadensis) were noted in plots 8 and 4, respectively. All plots will continue to be assessed during Year 5 monitoring for occurrence of volunteer species. 3.1.4 Vegetative Problem Areas During Year 4 monitoring, kudzu (Pueraria montana) was present on the Site in the vicinity of vegetation plot 13 and in the general vicinity. This concentration of kudzu was previously treated during construction in the spring of 2012, August 2014, October 2014, early August 2015, and late August 2015. The kudzu is located on the upstream portion of Reach M1, downstream of River-Siloam Road. This area was treated by use of the herbicides Glyphosate and Triclopyr. Any remaining kudzu in this area will be treated again during the early growing season 2016. Also, additional stream enhancement work along M1 and UT1 was completed in September 2015. During this time, the existing kudzu plants and roots were cleared within a large portion of the easement area. Property boundary fencing in the M1 vicinity was installed during the summer of 2015. This fence allows the landowner to graze cattle outside of the fenced conservation easement which will prevent kudzu re-establishment. Additional bare-root trees will be planted during the winter of 2015 in the riparian buffer areas along M1 and UT1 to increase density and to offset mortality from treating kudzu. Vegetation Plots 1 through 12 on reach M2 and M3 did not exhibit any invasive or aggressive species occurring on the Site. 3.1.5 Vegetation Photographs Photographs are used to visually document vegetation plot success. A total of 13 reference stations were established to document tree conditions at each vegetation plot across the Site. Reference photos of tree plots are taken at least once per year. Photos of the tree plots for Year 4 monitoring that show the on-site planted stems are included in Appendix A of this report. Candiff Creek Restoration Project, DMS Project No. 92767 November 2015, Monitoring Year 4 FINAL 13 3.2 Stream Assessment 3.2.1 Morphometric Success Criteria To document the stated success criteria, the following monitoring program was instituted following construction completion on the Site: Cross-sections: Two permanent cross-sections were installed per 1,000 LF of stream restoration work, with one of the locations being a riffle cross-section and one location being a pool cross-section in each series. A total of 10 permanent cross-sections were established across the Site. Each cross-section was marked on both banks with permanent pins to establish the exact transect used. The permanent cross-section pins are surveyed and located relative to a common benchmark to facilitate easy comparison of year-to-year data. The annual cross- section surveys include points measured at all breaks in slope, including top of bank, bankfull, inner berm, edge of water, and thalweg. The approved Mitigation Plan requires the following criteria be met to achieve stream restoration success:  There should be little change in as-built cross-sections  If changes do take place, they will be 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 banks, or decrease in width/depth ratio)  Cross-sections will be classified using the Rosgen Stream Classification System (Rosgen, 1994), and all monitored cross-sections should fall within the quantitative parameters defined for channels of the design stream type. Longitudinal Profiles: A complete longitudinal profile was surveyed following construction completion to record as-built conditions and to establish a baseline profile. The profile was conducted for the entire length of each restored channel for all reaches. Measurements included thalweg, water surface, inner berm, bankfull, and top of low bank. Each of these measurements was taken at the head of each feature (e.g., riffle, pool, and glide). In addition, maximum pool depth was recorded. All surveys were tied to a single, permanent benchmark. The approved Mitigation Plan requires the following criteria be met to achieve stream restoration success:  A longitudinal profile will be completed annually for the five-year monitoring period  The profile will be conducted for 3,000 LF of restored Candiff Creek channel  The longitudinal profiles should show that the bedform features are remaining stable; i.e., they are not aggrading or degrading  Pools should remain deep, with flat water surface slopes, and the riffles should remain steeper and shallower than the pools  Bedforms observed should be consistent with those observed for channels of the designed stream type. Candiff Creek Restoration Project, DMS Project No. 92767 November 2015, Monitoring Year 4 FINAL 14 3.2.2 Morphometric Results Year 4 cross-section monitoring data for stream stability was completed during September 2015. The 10 permanent cross-sections along the restored channels (5 located across riffles and 5 located across pools) were re-surveyed to document stream dimension at the end of Monitoring Year 4. Data from each of these cross-sections are presented in Appendix B. Tables B.1 through B.3 in Appendix B present visual stability assessment data, the baseline stream summary and the morphologic and hydraulic monitoring summary. Cross-sections 1, 4, 6, 8 and 10 are situated across riffles that are located between pools. Monitored cross-sections 1, 4, 6 and 8 are located on the upstream portion of M3 and based on the survey data, these cross-sections demonstrated minor fluctuations in riffle dimension during Year 4 of monitoring and currently remain stable. Additionally, cross-section 10 is located on the downstream portion of M3 and remains stable as well. Cross-sections 2, 3, 5, 7 and 9 are situated across pools, which are located at the apex of meander bends. Based on the Year 4 survey data, all five pool Cross-sections 2, 3, 5, 7 and 9 have demonstrated minor fluctuations in pool dimensions since as-built conditions. Based on the Year 4 monitoring survey data, all pool cross-sections show the development of point bar features on the inside banks of the meander bends. According to the Year 4 cross-section data, all cross-sections are currently meeting the success- criteria as stated in the Site Mitigation Plan. The longitudinal profile for Year 4 monitoring was also completed in September 2015. The Year 4 longitudinal profile monitoring data were compared to the data collected during the as- built condition survey completed in April 2012. During Year 4 monitoring, the longitudinal profile survey was completed for Reach M3. A total stream length of 3,150LF was surveyed for M3. The longitudinal profiles for M3 is presented in Appendix B. Year 4 monitoring data for the M3 longitudinal profile indicate that the riffles in this reach have essentially maintained the same bed elevations since as-built conditions. It was observed in most years including Year 4 that many pools in M3 have continued to increase in depth since as-built conditions. It is noted that increased pool depths were observed throughout most of M3. The deeper pools noted in M3 are benefiting the overall functionality of the Site by providing increased channel stability and also providing an area for energy dissipation while promoting greater habitat diversity. While the pools remain deep, the survey data indicate that the M3 riffles are stable. Additionally, the longitudinal profile for M3 demonstrates that the in-stream structures within the reach are stable and functioning as designed. According to the Year 4 longitudinal profile data, the restored stream thalweg is stable and currently meeting the success-criteria as stated in the Site Mitigation Plan. In-stream structures installed within the restored stream included constructed riffles, log vanes, rock j-hooks, log j-hooks, rock cross vanes, root wads and stream ford crossings. Visual observations of these structures throughout Year 4 monitoring indicate that all structures are functioning as designed and holding their post-construction grade. Structures that were installed to develop deeper pools, such as cross vanes and j-hooks, are performing their designed functions. Log vanes placed in meander areas have provided scour in pools to provide cover for aquatic wildlife. J-hooks placed in the lower end of the riffle areas have maintained riffle elevations and have provided downstream scour holes that provides aquatic habitat. Candiff Creek Restoration Project, DMS Project No. 92767 November 2015, Monitoring Year 4 FINAL 15 Additionally, bioengineered structures placed on the outside of meander bends have provided bank stability and in-stream cover for fish and other aquatic organisms. However, two minor pool problem areas were observed during Year 4 monitoring. These two areas are described in Section 3.2.5. 3.2.3 Hydrologic Criteria One crest gauge was installed on the Site to document bankfull events. The gauge is checked during each site visit and records the stage of the highest out-of-bank flow between site visits. The gauge is located on the left bank on the downstream portion of M3 at station 55+50. The approved Mitigation Plan requires the following criteria be met to achieve stream restoration success: Two bankfull flow events must be documented within the five-year monitoring period. The two bankfull events must occur in separate years, otherwise, the stream monitoring will continue until two bankfull events have been documented in separate years. 3.2.4 Hydrologic Monitoring Results According to the on-site crest gauge, the Site experienced at least two significant bankfull flow events during Year 4 monitoring. The largest on-site bankfull flow event documented at the M3 crest gauge occurred on April 20, 2015. It is estimated that the height of highest flow at the M3 crest gauge observed in Year 4 was approximately 2.85 feet above bankfull stage. A photograph depicting a large stump that washed up along M3 on October 4, 2015 is included in Appendix B. Since As-built conditions, seven documented bankfull events have been recorded as shown in Table 6. The approved Mitigation Plan requires that two bankfull flow events must be documented within the five-year monitoring period. Each of the four years of monitoring has documented at least one bankfull event within the restored channel. As such, the hydrologic success criteria for the Site has been met. Crest gauge readings are presented in Table 6 and photos of the crest gauges and out-of-bank evidence are presented in Appendix B. Table 6.

Bankfull benches were excavated and vertical stream banks were sloped to stable angles. In addition, vane structures and toe wood were installed along meander bends to protect the stream banks, provide additional habitat, and to provide long-term stream bank stabilization. No additional credit is being requested as a result of this work. During this time, the existing kudzu plants and roots were cleared within a large portion of the easement area. Per the permit conditions for the enhancement work, monitoring along M1 and UT1 will be conducted for a minimum of one additional year beyond the monitoring required in the mitigation plan. This monitoring will include visual assessments conducted twice per year and the installation and annual monitoring of two bank pin arrays installed in the outside of meander bends. Two pools located at stations 46+50 and 55+50 have exhibited areas of erosion during Year 4 monitoring. The erosional areas observed are occurring on the outer bend below the root wads and are approximately 10 feet or less in length. These two minor problem areas make up approximately 0.2% of the total as-built stream length of 5,095 feet. Photos of these two areas are included in the Appendix. These areas are isolated and do not suggest a trend towards long-term instability. 3.2.6 Stream Photographs Photographs are used to document restoration success visually. A total of 59 reference stations were installed and photographed after construction. Photographs of these reference stations will be collected for at least five years following construction. Reference photos are taken at least twice per year, and are taken in enough locations to document the condition of the restored system. Permanent markers were established to ensure that the same locations (and view directions) on the Site are documented in each monitoring period. The stream systems are photographed longitudinally, beginning at the downstream portion of the restoration reaches, and moving upstream to the beginning of the reaches. Photographs are taken looking upstream at designated locations. Reference photo locations are marked and described for future reference. Points are spaced sufficiently close to provide an overall view of the reach. The angle of the photograph depends on which direction provides the best view and is noted and will be continued for future photos. When modifications to photo position and/or direction are made due to obstructions or other reasons, the modified photo position and/or direction is noted, along with any landmarks. The modified position is used in all future photographs of that site. Additional photographs are taken to document any observed evidence of flooding patterns such as debris, wrack lines, water marks, channel features, etc. Also, both stream banks are photographed at all permanent cross-section photo stations. For each stream bank photo, the photo view line follows a survey tape placed across the channel, perpendicular to flow (representing the cross-section line). The photograph is framed so that the survey tape is centered in the photo (appears as a vertical line at the center of the photograph), keeping the channel water surface line horizontal and near the lower edge of the frame. In each cross-section photo showing the left bank, flow is moving to the right. Conversely, in each cross-section photo showing the right bank, flowing is moving to the left. Candiff Creek Restoration Project, DMS Project No. 92767 November 2015, Monitoring Year 4 FINAL 17 A photo log of the restored channel is presented in the attached CD of this report. Photos for each of the 10 permanent cross-sections are included in Appendix B. Photographs of the restored channel were taken in October 2015 to document the evolution of the stream geometry. Herbaceous vegetation and shrubs were dense along the banks of M2 and M3, making the photography of some of the stream channel areas difficult. Additionally, photographs of the enhancement work performed along M1 and UT1 are provided in Appendix B. 3.2.7 Stream Stability Assessment Table B.1 provides a summary of the results obtained from the visual inspection of in-stream structures performed during Year 4 monitoring. The percentages noted are a general, overall field evaluation of the how the features were performing at the time of the photo point survey. According to the visual stability assessment following Year 4 monitoring, and after a visual evaluation throughout 2015, it was determined that all features at the Site along M2, M3, and UT2 are currently performing as designed. With the recent enhancement activities, kudzu treatment, and planned re-planting, the features along M1 and UT1 will meet performance standards. 3.2.8 Quantitative Measures Summary Tables The quantitative pre-construction, reference reach, and design data used to determine restoration approach, as well as the as-built baseline data used during the project’s post construction monitoring period are summarized in Appendix B. Candiff Creek Restoration Project, DMS Project No. 92767 November 2015, Monitoring Year 4 FINAL 18 4.0 OVERALL CONCLUSIONS AND RECOMMENDATIONS Stream Monitoring - The total length of stream channel restored, enhanced and/or preserved on the Site was 7,038 LF. The project involved the restoration of 4,081 linear feet (LF) of stream along M3. Additionally 1,757 of stream Enhancement (265 LF of Enhancement I along M2 and 1,492 LF of Enhancement II along M1, UT1 and UT2) and 1,200 LF of stream preservation along UT1 and UT2. This entire length was inspected during Year 4 monitoring to assess stream performance. Excluding M1 and UT1 which have been discussed above with issues that are actively being addressed, the Year 4 monitoring did not reveal any significant problem areas within the boundaries of the Site. Cross-section monitoring data for stream stability were collected during Year 4 monitoring. Additionally, a longitudinal profile survey was also completed during Year 4 monitoring for approximately 3,150 LF of stream on the Site. The longitudinal profile was completed for Reach M3 only. Year 4 monitoring data for the M3 longitudinal profile show that the riffles in this reach have maintained relatively the same bed elevations since as-built conditions. The longitudinal profile demonstrates that the in-stream structures within M3 are stable and functioning as designed. The Year 4 cross-sectional data also indicate that Reach M3 is stable and functioning as designed. According to the on-site crest gauge, the Site experienced at least two significant bankfull flow events during Year 4 monitoring. The largest on-site bankfull flow event documented at the M3 crest gauge occurred on April 20, 2015. It is estimated that the height of highest flow at the M3 crest gauge observed in Year 4 was approximately 2.85 feet above bankfull stage. Since As-built conditions, seven documented bankfull events have been recorded as shown in Table 6. The approved Mitigation Plan requires that two bankfull flow events must be documented within the five-year monitoring period. Given that each of the four years of monitoring has documented a bankfull event within the restored channel, it is noted that the hydrologic success criteria for the Site has been met. Two pools located at stations 46+50 and 55+50 have exhibited areas of erosion during Year 4 monitoring. The erosional areas observed are occurring on the outer bend below the root wads and are approximately 10 feet or less in length. These areas are isolated and do not suggest a trend towards long-term instability. Additional stream enhancement work along M1 and UT1 was completed in September 2015. Bankfull benches were excavated and vertical stream banks were sloped to stable angles. In addition, vane structures and toe wood were installed along meander bends to protect the stream banks, provide additional habitat, and to provide long-term stream bank stabilization. No additional credit is being requested as a result of this work. Vegetation Monitoring - Data from Year 4 monitoring for the 13 vegetation plots exhibited a range of 40 to 931 stems per acre. The data showed that the Site had an average of survivability of 735 stems per acre. During Year 4 monitoring, kudzu (Pueraria montana) was present on the Site in the vicinity of vegetation plot 13 and in the general vicinity. This concentration of kudzu was previously treated during construction and remnants are still present within the easement. The kudzu is located on the upstream portion of Reach M1, downstream of River-Siloam Road. This area was treated once in early August 2015 and once in late August 2015 by use of the herbicides Glyphosate and Candiff Creek Restoration Project, DMS Project No. 92767 November 2015, Monitoring Year 4 FINAL 19 Triclopyr. Any remaining kudzu in this area will be treated again during the early growing season 2016. Also, additional stream enhancement work along M1 and UT1 was completed in September 2015. Bankfull benches were excavated and vertical stream banks were sloped to stable angles. In addition, vane structures and toe wood were installed along meander bends to protect the stream banks, provide additional habitat, and to provide long-term stream bank stabilization. No additional credit is being requested as a result of this work. During this time, the existing kudzu plants and roots were cleared within a large portion of the easement area. Vegetation Plots 1 through 12 on reach M2 and M3 did not exhibit any invasive or aggressive species occurring on the Site. Property boundary fencing in the M1 vicinity was installed during the summer of 2015. This fence allows the landowner to graze cattle outside of the fenced conservation easement which will prevent kudzu re-establishment. Additional bare-root trees will be planted during the winter of 2015 in the riparian buffer areas along M1 and UT1 to increase density and to offset mortality from treating kudzu. 5.0 WILDLIFE OBSERVATIONS Observations of deer and raccoon tracks are common at the Site. During Year 4 monitoring, small animals such frogs, rodents, snakes, and fish were periodically observed. Various songbirds and birds of prey were observed on the Site throughout Year 4 monitoring.
