Candiff Creek Restoration Project, EEP Project No. 92767 111 February 2014, Monitoring Year 2 FINAL 1.0 EXECUTIVE SUMMARY This Annual Monitoring Report details the monitoring activities during the 2013 growing season (Monitoring Year 2) for the Candiff Creek Restoration Project ( "Site "). 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 (m) (10m x 10m) in size, are used to predict survivability of the woody vegetation planted on the Site. Data from Year 2 monitoring for the 13 vegetation plots exhibited a survivability range of 648 to 1,052 stems per acre. The data showed that the Site had an average survivability of 818 stems per acre following Year 2 monitoring. According to the Year 2 vegetative monitoring data, the Site is on track to meet the interim success criteria of a minimum of 320 stems per acre by the end of Monitoring Year 3. Cross - sectional monitoring data for stream stability were collected during Year 2 monitoring. A longitudinal profile survey was completed during Year 2 monitoring for approximately 3,674 linear feet (LF) of stream on the Site. The longitudinal profile was completed for Reach M3 only. The cross - sectional data and the longitudinal profile indicate that Reach M3 is stable and functioning as designed. According to the on -site crest gauge, the Site experienced at least two bankf ill flow events during the Year 2 monitoring period. The largest on -site bankf ill flow event documented by the M3 crest gauge during Year 2 monitoring, occurred on January 18, 2013. It is estimated that the height of highest flow at the M3 crest gauge observed in January was approximately 2.49 feet above bankfull stage. Inspection of conditions during a spring site visit revealed visual evidence of out -of -bank flows. In summary, the Site is on track to meet the hydrologic, vegetative, and stream success criteria as specified in the Site Restoration Plan. Candiff Creek Restoration Project, EEP Project No. 92767 l February 2014, Monitoring Year 2 FINAL 2.0 PROJECT BACKGROUND The project involved the proposed restoration of 4,109 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 I and Figure 2 summarize 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 Engineering, Inc. (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 UT 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 MI/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. UTI 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 designed bankfull elevation, 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 Candiff Creek Restoration Project, EEP Project No. 92767 2 February 2014, Monitoring Year 2 FINAL stabilized using a combination of erosion control matting, temporary and permanent seeding, bare - root planting, 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 (USES) targeted local watershed 03040101, and the North Carolina Division of Water Quality (NCDWQ) sub -basin 03 -07- 02. 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 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 bankf ill 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 present vegetation metadata, vegetation vigor, vegetation damage and stem count data for the monitoring stations at the end of Year 2 monitoring. Data from Year 2 monitoring for the 13 vegetation plots exhibited a range of 648 to 1,052 stems per acre. The data show that the Site had an average survivability of 819 stems per acre following Year 2 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 removed from each stem once the tree becomes established and is recognizable by species during plot monitoring. Flags are also used to mark trees because they do not interfere with the growth of the tree. During Year 2 monitoring no significant population of volunteer species were noted on the Site. All plots will continue to be assessed during Year 3 monitoring for occurrence of volunteer species. 3.1.4 Vegetative Problem Areas During Year 2 monitoring, kudzu (Pueraria montana) was observed on the Site in the vicinity of vegetation Plot 13 and in the general vicinity. This concentration of kudzu was previously treated during construction but is now re- establishing in the same location. The kudzu is located on the upstream portion of Reach M1, downstream of River - Siloam Road. This area is scheduled to be treated in May of 2014 during the appropriate treatment window by use of the herbicides Glyphosate and Triclopyr. Vegetation Plots 1 through 12 exhibit relatively few weedy species occurring on the Site, and none of the on -site species seem to be posing any issues for the planted woody or herbaceous hydrophytic vegetation at this time. 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 2 monitoring that show the on -site planted stems are included in Appendix A of this report. 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: Candiff Creek Restoration Project, EEP Project No. 92767 11 February 2014, Monitoring Year 2 FINAL 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. 3.2.2 Morphometric Results Year 2 cross - section monitoring data for stream stability was completed during October 2013. 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 2. Data from each of these cross - sections are presented in Appendix B. Candiff Creek Restoration Project, EEP Project No. 92767 12 February 2014, Monitoring Year 2 FINAL Cross - sections 1, 4, 6, 8 and 10 are situated across riffles that are located between pools. Based on the survey data, Cross - section 10 located on the mid - downstream portion of M3, showed relatively little change since as -built conditions. Cross - sections 1, 4, 6 and 8 are located on the upstream portion of M3 and demonstrated minor fluctuations in riffle dimensions during the first and second years of monitoring. Cross - sections 1 and 4 appear to have aggraded in channel dimension slightly since as -built conditions and Year 1. These two cross - sections were observed during Year 2 monitoring and appear to be stable. Cross - section 6 is located mid - stream on reach M3. This Cross - section has shifted slightly downward since Year 1. This shift is likely due to riffle adjustment and maturation. Cross - section 6 will be closely observed during Year 3 monitoring for any shift toward instability. Cross - sections 2, 3, 5, 7 and 9 are situated across pools which are located at the apex of meander bends. Based on the survey data, all five pool Cross - sections 2, 3, 5, 7 and 9 have demonstrated minor fluctuations in pool dimensions since as -built conditions. It is noted that these pool cross - sections have deepened in the thalweg since as -built conditions. Based on the Year 2 monitoring survey data, all pool cross - sections show the slow development of point bar features on the inside banks of the meander bends. The longitudinal profile for Year 2 monitoring was completed in October 2013. The Year 2 longitudinal profile monitoring data were compared to the data collected during the as -built condition survey completed in April 2012 and the Year 1 data collected in October 2012. During Year 2 monitoring, the longitudinal profile survey was only completed for Reach M3. A total stream length of 3,674 LF was surveyed for M3. The longitudinal profiles for these reaches are presented in Appendix B. Year 2 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 Year 1 and in Year 2 that some pools in M3 have continued to increase in depth since as -built conditions. It is noted that increased pool depths were observed mostly in the middle of portion of M3. The deeper pools noted in M3 are benefiting the overall functionality of the Site by providing increased channel stability while promoting greater habitat diversity. Overall, the longitudinal profile for M3 demonstrates that the in- stream structures within the reach are stable and functioning as designed. In- stream structures installed within the restored stream included constructed riffles, log vanes, grade control rock and log j -hook vanes, rock cross vanes, root wads and stream crossings. Visual observations of these structures throughout Year 2 monitoring indicated that all structures are functioning as designed and holding their post - construction grade. Structures that were installed to develop deep pools, such as cross vanes and j- hooks, are performing their designed functions. Log vanes placed in meander pool areas have provided scour to keep pools deep and provide cover for fish. J -hooks placed in lower end of the riffle areas have maintained riffle elevations and provided downstream scour holes that provides aquatic habitat. Root wads placed on the outside of meander bends have provided bank stability and in- stream cover for fish and other aquatic organisms. 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 Candiff Creek Restoration Project, EEP Project No. 92767 13 February 2014, Monitoring Year 2 FINAL 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 2 monitoring. The largest on -site bankfull flow event documented at the UT 1 crest gauge during Year 2 monitoring, occurred in on January 18, 2013. It is estimated that the height of highest flow at the M3 crest gauge observed in January was approximately 2.49 feet above bankfull stage. Following the January event, the next recorded observation occurred approximately on July 5, 2013. The crest gauge on M3 did not document additional out of channel bankfull flows for the remainder of Year 2 monitoring. 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.

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 Candiff Creek Restoration Project, EEP Project No. 92767 14 February 2014, Monitoring Year 2 FINAL 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 right. Conversely, in each cross - section photo showing the right bank, flowing is moving to the left. 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 May and November 2013 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. 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 2 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 2 monitoring, and after a visual evaluation throughout 2013, it was determined that all features at the Site are currently performing as designed. However, it is noted that the pool in Cross - section 7 has recovered from aggrading in Year 1 and is deepening as designed. This pool will be observed during Year 3 monitoring and future site visits for any significant changes. 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, EEP Project No. 92767 15 February 2014, Monitoring Year 2 FINAL 4.0 OVERALL CONCLUSIONS AND RECOMMENDATIONS Stream Monitoring - The total length of stream channel restored on the Site was 4,123 LF. This entire length was inspected during Year 2 monitoring to assess stream performance. Year 2 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 2 monitoring. A longitudinal profile survey was also completed during Year 2 monitoring for approximately 3,674 LF of stream on the Site. The longitudinal profile was completed for Reach M3 only. Year 2 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 cross - sectional data and the longitudinal profile 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 2 monitoring. The largest on -site bankfull flow event documented at the UT1 crest gauge during Year 2 monitoring, occurred in on January 18, 2013. It is estimated that the height of highest flow at the M3 crest gauge observed in January was approximately 2.49 feet above bankfull stage. Following the January event, the next recorded observation occurred approximately on July 5, 2013. The crest gauge on M3 did not document additional out of channel bankfull flows for the remainder of Year 2 monitoring. Vegetation Monitoring - Data from Year 2 monitoring for the 13 vegetation plots exhibited a range of 648 to 1,052 stems per acre. The data showed that the Site had an average of survivability of 818 stems per acre. During Year 2 vegetation monitoring, kudzu was observed on the Site in the vicinity of vegetation Plot 13 and in the general vicinity. This concentration of kudzu was previously treated during construction but is now re- establishing in the same location. The kudzu is located on the upstream portion of Reach M1, downstream of River - Siloam road. This area is scheduled to be treated in May of 2014 during appropriate treatment window(s). The kudzu is to be treated in the early growth season by use of the herbicides Glyphosate and Triclopyr. According to the Year 2 vegetative monitoring data, the Site is on track to meet the interim success criteria of 320 stems per acre by the end of Year 3 monitoring. 5.0 WILDLIFE OBSERVATIONS Observations of deer and raccoon tracks are common at the Site. During Year 2 monitoring, small animals such frogs, rodents and fish were periodically observed. Various songbirds and birds of prey were observed on the Site throughout Year 2 monitoring. Wild turkeys are also commonly observed in the area. Candiff Creek Restoration Project, EEP Project No. 92767 16 February 2014, Monitoring Year 2 FINAL 6.0 REFERENCES Rosgen, D. L. 1994.
