sectional monitoring data for stream stability were collected during Year 1 monitoring A longitudinal profile survey was completed during Year 1 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 one bankfull flow event during the Year 1 monitoring period The largest on -site bankfull flow event documented by the M3 crest gauge during Year I monitoring, occurred sometime in April -May 2012 It was estimated that flows at the M3 crest gauge during this time period were approximately 160 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 January 2013, Monitoring Year 1 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 1 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 floodplam, 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 >n- 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 "mamstem" and a "UT" designation for unnamed tributaries Two UTs are located on the Site (labeled UTI 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 Ml/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 Ml/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 floodplam, 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 /rocky -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 January 2013, Monitoring Year 1 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 Candiff Creek Restoration Project, EEP Project No 92767 3 January 2013, Monitoring Year 1 FINAL 'T. 161. 1 nom {....

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 gerardn), beggartick (Bidens frondosa), lanceleaf tickseed (Coreopsis lanceolata), deertongue (Pancium clandestinum), Virginia wildrye (Elymus virginicus), soft rush (Juncus effusus), switchgrass (Panicum virgatum), smartweed (Polygonum pensylvanicum), 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 CandlffCreek Restoration Project, EEP Project No 92767 9 January 2013, Monitoring Year I FINAL Table 3 Vegetation Species Planted Across the Restoration Project Species Scientific Name Common Name Pei-cent Planted by Total Number of Stems Bare Root Trees Species Betula nigra river birch 233% 1,800 Diospyros virgintana persimmon 78% 600 Fraxinus pennsylvantca green ash 156% 1,200 Ltriodendron tulipfera tulip poplar 78% 600 Platanus occidentahs sycamore 221% 1,700 Quercus mtchauxtt swamp chestnut oak 156% 1,200 Quercus phellos willow oak 78% 600 Bare Root Shrub Species Asimina triloba paw paw 95% 400 Carpinus carohniana ironwood 12% 500 Cercus canadensts redbud 14% 600 Cornus amomum silky dogwood 19% 800 Lindera benzoin spicebush 95% 400 Sambucus canadensts elderberry 19% 800 Viburnum dentatum arrowwood 17% 700 Native Herbaceous Species Agrostis alba redtop 10% NA Andropogon gerardit big bluestem 5% NA Bidens frondosa devil's beggartick 5% NA Coreopsis lanceolata lanceleaf tickseed 10% NA Dichanthehum clandestinum deertongue 15% NA Elymus virginicus Virginia wild rye 15% NA Juncus effusus soft rush 5% NA Panicum vitgatum switchgrass 15% NA Polygonum pennsylvanicum Pennsylvania smartweed 5% NA Schizachyrium scoparium little bluestem 5% NA Sorghastrum nutans Indiangrass 5% NA Tripsacum dactyloides eastern gamagrass 5% NA Woody Vegetation for Live Stakes Cornus amomum silky dogwood 30% 2,100 Salix sertcia silky willow 30% 2,100 Salix nigra black willow 10% 700 Sambucus canadensts elderberry 1 30% 1 2,100 CandiffCreek Restoration Project, EEP Project No 92767 10 January 2013, Monitoring Year 1 FINAL 3.1.3 Vegetative Observations and Results Permanent ground cover has been successfully established at the Site through the planting of the permanent seed mixture planted at the Site, as observed during Year 1 monitoring of the Site 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 4 monitoring Data from Year 1 monitoring for the 13 vegetation plots exhibited a range of 728 to 1,052 stems per acre The data show that the Site had an average survivability of 878 stems per acre following Year 1 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 All plots will continue to be assessed during Year 2 monitoring for occurrence of volunteer species - 3.1.4 Vegetative Problem Areas During Year 1 monitoring, kudzu (Pueraria montana) was observed on the Site in the vicinity of vegetation Plot 13 This concentration of kudzu is located on the upstream portion of Reach M1, downstream of River - Siloam road This area of kudzu was previously treated during construction This area of kudzu is scheduled to be treated again during the appropriate time(s) in 2013 There are 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 1 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 1 1 January 2013, Monitoring Year 1 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 1 cross - section monitoring data for stream stability was completed during October 2012 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 1 Data from each of these cross - sections are presented in Appendix B CandlffCreek Restoration Project, EEP Project No 92767 12 January 2013, Monitoring Year 1 FINAL Cross - sections 1, 4, 6, 8 and 10 are situated across riffles that are located between pools Based on the survey data, Cross - sections 6, 8 and 10, located on the mid- downstream portion of M3, showed relatively little change since as -built conditions Cross - sections 1 and 4 are located on the upstream portion of M3 and demonstrated minor fluctuations in riffle dimensions during the first year of monitoring Cross - sections 1 and 4 appear to have aggraded in channel dimension slightly since as -built conditions The left bank of Cross- section 1 also appears to have increased in elevation It is likely that the changes observed in Cross - sections 1 and 4, both at riffles, are due to the spring rains which also marked the highest bankfull readings for Year 1 monitoring These two cross - sections will be closely observed during Year 2 monitoring 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, Cross - sections 2, 3 and 5 have shown relatively little change since as -built conditions However, Cross - sections 7 and 9 have demonstrated minor fluctuations in pool dimensions since as -built conditions Cross - sections 7 and 9 are located on the downstream portion of M3 and appear to have aggraded slightly since as -built conditions It is likely that the morphological changes observed in Cross - sections 7 and 9, both at pools, are also due to the spring rains Based on the Year 4 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 1 monitoring was completed in October 2012 The Year 1 monitoring data were compared to the data collected during the as -built condition survey completed in April 2012 During Year 1 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 1 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 However, 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 in M3 are providing increased channel stability while promoting greater habitat diversity It is likely that the morphological changes observed in Cross - sections 7 and 9, both at pools, are again attributed to the spring rains 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 1 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 Candiff Creek Restoration Project, EEP Project No 92767 13 January 2013, Monitoring Year 1 FINAL 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 one bankf ill flow event during Year lmomtoring The largest on -site bankfull flow event documented at the UT1 crest gauge during Year 1 monitoring, occurred in April -May 2012 It is estimated that the stage of the highest flow at the M3 crest gauge during April -May 2012 was approximately 160 feet above bankfull stage Following the April -May 2012 storm events, the crest gauge on M3 did not document additional out of channel bankfull flows for the remainder of Year 1 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.

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 October 2012 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 1 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 1 monitoring, and after a visual evaluation throughout 2012, 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 aggraded slightly This pool will be closely observed during Year 2 monitoring and future site visits 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 Candlff Creek Restoration Project, EEP Project No 92767 15 January 2013, Monitoring Year 1 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 1 monitoring to assess stream performance Year 1 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 1 monitoring A longitudinal profile survey was also completed during Year 1 monitoring for approximately 3,674 LF of stream on the Site The longitudinal profile was completed for Reach M3 only Year 1 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 one bankfull or greater flow event during Year 1 monitoring The largest on -site bankfull flow event documented by the M3 crest gauge during Year 1 monitoring occurred approximately in April -May 2012 It was estimated that the stage associated with these flows at the M3 crest gauge during this period was approximately 160 feet above banlAll stage Inspection of conditions during a spring site visit revealed visual evidence of out -of -bank flows Vegetation Monitoring - Data from Year 1 monitoring for the 13 vegetation plots exhibited a range of 728 to 1,052 stems per acre The data showed that the Site had an average of survivability of 878 stems per acre During Year 1 vegetation monitoring, kudzu was observed on the Site in the vicinity of vegetation Plot 13 This concentration of kudzu is located on the upstream portion of Reach Ml, downstream of River - Siloam road This area of kudzu was previously treated during construction This area is scheduled to be treated again in 2013 during appropriate treatment window(s) According to the Year 1 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 Candiff Creek Restoration Project, EEP Project No 92767 16 January 2013, Monitoring Year 1 FINAL 5.0 WILDLIFE OBSERVATIONS Observations of deer and raccoon tracks are common at the Site During Year 1 monitoring, many small animals such as snakes, frogs and rodents were periodically observed Various songbirds and birds of prey were observed on the Site throughout Year 1 monitoring Wild turkeys are also commonly observed in the area 6.0 REFERENCES Rosgen, D L 1994 A Classification of Natural Ravers Catena 22 169 -199 Cowardm, L M , V Carter, F C Golet, E T LaRoe 1979 Classification of wetlands and deepwater habitats of the United States U S Department of the Interior, Fish and Wildlife Service, Washington, D C USDA, Natural Resource Conservation Service, Soil Survey of Surry County, North Carolina, 2007 Candiff Creek Restoration Project, EEP Project No 92767 17 January 2013, Monitoring Year 1 FINAL FIGURES Project Location 10 0.5 1 2 3 Miles CO T Yr r►ei� r��•�� may, Surry County m! y, %r � l \� Yadkin River NCDVW Sub -Basin 03-07 -02 8 Digit HIIC -
