With almost a mile in stream length relocated, this project was a large scale relocation of a Class C, headwater stream in the Piedmont region that has intermittent flow in the upstream section to no stream flow in the lower section and has major impacts from stormwater runoff upstream. Added to the complexity of the length was the creation of the stream channel in subsurface soils - saprolite and gravel pit substrate with little to no topsoil. The UTA and UTB were relocated as small, headwater streams through a site that frequently sees the two streams drying out and becoming intermittent in the dry months of the year. Riparian conditions (wet, damp soils) are limited to the immediate vicinity of the stream bed in this case and only in the upper sections of the stream. The rest of the project buffer area consists of sloped, xeric conditions with poor soil conditions and little to no flow except during rain events. The stormwater runoff in the past had created major gully conditions in the existing UTA as shown by the photograph from 2005. Martin Marietta addressed the erosion through the relocation of the stream and by installing a stormwater retention basin outside of the stream relocation project, in order to manage the off-site flood impacts to the existing and new stream channel. The photo from 2017 shows the same area post- construction of the relocated stream. UTA 2005 UTA 2017 Martin Marietta — Bonds Quarry Stream Relocation Report of Findings — Monitoring Report Year Four October 2017 Page 1 E. McGill ASSOCIATES As discussed in the Problem Areas Section of the report, the evolution of the project to address the intermittent, flashy stream flow has shown slow but steady progress. Of the total 5100 linear feet of relocated stream channel, problem areas as discussed in the report totaled only 350 linear feet, or 6.8% of the total stream channel. The lower 300 linear foot section at the bottom of the stream relocation has been repaired and is growing new vegetation. The remaining problem areas are less than 1% of the total length of the project. This was overall a successful relocation and creation of a stable stream system that was in poor condition in its previous location through the quarry. Based on the successful relocation and stabilization of the stream channel, Martin Marietta would like to reduce the amount of stream monitoring that is designed for larger, perennial stream channels. The current longitudinal profile, BEHI, cross section surveys, pebble counts, live stake plots, and photo stations for channel pattern documentation does not provide good information on the small intermittent to dry stream conditions. For the final year, Martin Marietta would recommend reducing the annual monitoring to the following: Photodocumentation of the project stream and buffer photographs, cross section and longitudinal profiles at problem sites, problem area photographs, streambank erosion monitoring and information on repairs and replantings as needed performed by Martin Marietta in future years. Project Site Martin Marietta relocated 4700' of UTA to the eastern boundary of the property down to the discharge into the Rocky River at the southern end of the project area. Along with the relocation of UTA, 400' of UTB on the property was relocated from Weddington Road to its confluence with the relocated UTA. Preconstruction conditions are documented in the photographs in Appendix A. The relocated stream was constructed to the east of the existing quarry site. Buffers for the relocated stream were restored and planted and protected under a recorded Conservation Easement held by Cabarrus County. The pattern, profile and dimension were restored for the two streams within the project site. This Annual Report will summarize the monitoring efforts performed during 2017 (Year 4) at the Bonds Quarry Site Table 1. Summary of As -built Lengths and Restoration Approaches.

Longitudinal profiles will be taken every other year for a total of 3 profiles over the monitoring period. There were six cross sections, three livestake plots, and four vegetative monitoring plots established along the project stream. Pre -Construction Conditions 2005 Pre -construction observations in summer of 2005 of the streams UTA and UTB showed impacts from the upstream commercial use in the headwaters of the two streams. Photographs of the pre - construction conditions can be found in Appendix A. UTA appeared to be very stable in the upper reach on the property with well vegetated banks and buffer. Most of this upper section would not be impacted by the restoration project. At the confluence of UTA and UTB and a stormwater drainage way, UTA became extremely entrenched with severe bank erosion. In the lower sections, UTA was impacted indirectly by the removal of groundwater nearby due to quarry activities which resulted in the removal of all flow during the dry months. Martin Marietta. — Bonds Quarry Stream Relocation Report of Findings — Monitoring Report Year Four October 2017 Page 6 E. McGill ASSOCIA rES UTB is an intermittent stream that is heavily impacted by stormwater flows from commercial impervious areas upstream of the project site. Photographs of the old channel are shown in Appendix A. On the project site, the stream showed heavy sedimentation impacts during high water events. Downstream as it neared the confluence with UTA, it became severely entrenched and headcutting of the stream channel was only controlled through bedrock substrate in this area. As Built 2011 As built plan sheets for this project are shown in Appendix B and were submitted to the agencies in February 2012. The active project construction extended over a long period of time with more than a year in construction and planting activities for the project. As can be seen on the timetable of the project history, the stream restoration project phases were completed at varying time from 2008-2013 due to the length and complexity of the project. Vegetation planting efforts were spread throughout this period. Post Monitoring Year 4 VISUAL OBSERVATIONS Visual observations were conducted on the entire project. In stream structures were assessed for functionality and erosion concerns. Stream banks, side slopes and buffer areas were evaluated for stability and erosion problems. Visual observations were used to evaluate the overall success of the project. UTB: The stream channel was stable, and stream banks showed no sign of erosion. Vegetative growth continued to be good and consisted of walnut, yellow poplar, river birch, hickory and oaks volunteers with cattails, sedges, and juncus species in wet spots. There was little to no flow in this stream in May 2017. Photographs can be seen in Appendix C. UTA: This stream continued to show a mixture of hardwoods and evergreens in the upper section of the project where the stream flow was perennial in nature. There was a wetland forming at the junction of UTA and UTB. Along the stream channel black willow, silky willow, river birch, water oak, cattails, juncus sp. and carex sp. were common. Upslope white pine, sweet gum, Eastern false willow, willow oak, yellow poplar, and sycamore could be found. Ground cover was provided by Lespedeza sp, blackberry, goldenrod, trumpeter vine, daisy, and dog fennel along with unknown grass species. Blueberry where planted were still surviving. Growth of trees and shrubs were best in the upper, perennial flow section of the stream. As the buffer progressed downstream, vegetation was reduced to white pine and Lespedeza except where pools and springs entered the stream. By the lower end of the stream project, the stream flow was only stormwater flows and little to no riparian vegetation could be found. At the regraded end of the project before the confluence with the Rocky River, the regrading and the level spreader was beginning to look more like a wetland area with no stream channel. Over Martin Marietta — Bonds Quarry Stream Relocation E. McGill Report of Findings —Monitoring Report Year Four October 2017 ASSOCIATES Page 7 time it will be seen if a channel develops in this area that only flows during storm events. There was no flow in May 2017 during the monitoring, but the area was showing some indications of hydric conditions forming. Other areas in the buffer had bare rock exposed with no vegetation established. Photographs can be seen in Appendix C. Aquatic organisms were observed in flowing channels and stream pools and included minnows, dragonfly larvae, caddisfly larvae, snails, tadpoles, and turtles. Algae was noted growing on some rocks. The water quality appeared to be good with clear visibility and no signs of pollution or sedimentation. VEGETATIVE MONITORING PLOTS General: Vegetative and livestake monitoring results and photographs are found in Appendix D. In general, the plots in reaches with perennial or more consistent stream flow are doing well and establishing stability for the streambanks and buffer around the project stream. Where there is limited to no stream flow except for rain storm events, the vegetation growth of the riparian species planted for the project are not surviving or doing poorly. These drier areas, however, are being naturalized by local upland species where the soil conditions allow (still areas of bare rock and exposed pit gravel) and appear to be well on the way to naturally stabilizing the area. Monitoring Plot #1 : This 25' by 50' vegetation survey plot was established in the stream reach classification C of the relocation project. The first year monitored showed very few planted trees present (no as -built count was made during initial plantings). More trees and shrubs were planted in MY2. Over the four years, survival of planted species has dropped to 33% with total stems/acre of 260. The originally planted species of blueberry and river birch were in good to excellent condition and were well established. Combined with the volunteer species of white pine and sweet gum, the abundant native species contributes to the stability and overall success of the reach. No remediation is recommended at this time. Monitoring Plot #2: This 25' x 50' vegetation survey plot was established in the stream reach classification B of the relocation project, on the upper end. Seven planted blueberry plants were counted the first year with three surviving through MY4. Other plants have been planted over the years to improve the stem count for this buffer area in general, but the soil conditions are so poor that survival has been dropping to 43%. New volunteer stems of white pine and eastern false willow that are in excellent condition and well established are showing that naturalized recovery is expected for this plot and have added to the total 120 stems/acre. No remediation is recommended at this time. Monitoring Plot #3: A 25' x 50' vegetation survey plot established in the lower section of the stream reach classification B restoration section. An initial planting of blueberry, rhododendron, and possibly eastern false willow of 11 stems were counted the first year and additional river birch trees were planted the second year bringing the count to 18 or 400 stems/acre. Survival has dropped to 33% with the loss of most of the blueberry shrubs. Native species of oak and eastern false willow have increased the naturalization to a stable and successful 500 stems/acre in MY4. No remediation is recommended at this time. Martin Marietta — Bonds Quarry Stream Relocation E, McGill Report of Findings —Monitoring Report Year Four October 2017 A S S O C: i A T E S Page 8 Monitoring Plot #4: A 25'x 50' vegetation survey plot was established in the lower stream reach classification of E/C restoration section. The first year only 3 live blueberry plants present, due to soil conditions and erosion from flood events in 2013, both from overflows from UTA and from the Rocky River backing up into the section. Additional plants were planted in 2015 but no survival was noted in 2016. This area was regraded in 2016 into a more stable floodplain configuration to take into account the dry stream conditions in summer and the high flood waters during stormwater events. This plot was reset in a new location within the reach. Completely replanted in the winter of 2016-2017, there are currently 23 planted stems (580 stems/acre) in the monitoring plot. The landscaper planted rooted plants available at local nurseries and the species are all ornamentals or non-native species. There are also indications in the plot that the regrading has created suitable conditions to form wetlands in the area which may prevent survival of these planted species. In the adjacent area there are volunteers of the Eastern false willow which is FACW species and may naturalize the area in the coming years. No remediation is recommended at this time until the soil conditions in this section stabilize as either dry/wet. Livestake Plot #1: A plot of 50' long was established on both sides of the stream and planted with livestakes and rooted trees. Survival within the streambanks was excellent over the years, with little to no survival outside the stream channel. Some shading out of species has occurred with the excellent growth of the black willow trees/silky willow shrubs, leading to a natural decrease in the number of stems within this plot (from 121 to 86). The abundant native species contributes to the stability and overall success of the reach and no remediation is recommended at this time. Livestake Plot #2: A plot of 50' long was established on both sides of the stream and planted with livestakes and rooted trees. Almost no survival of plantings was observed since MY1 due to the lack of stream flow/riparian conditions in this section of the project. During May 2017, there was a minimal amount of water flow, a trickle, in the stream channel. All of the riparian species planted would not be able to survive in these conditions unless planted directly into the stream channel. This is not recommended and it is recommended that this area will be naturalized with native trees suitable for upland, drier soil conditions. No Livestake monitoring plot would be appropriate for this section of the project. Livestake Plot #3: A plot of 50' long was established roughly on both sides of the stream channel and planted with livestakes and rooted trees. The initial dimension and pattern was unstable and led to excessive streambank erosion shortly after as built construction. In 2016 this area was completely regraded to a new floodplain configuration that was more suitable to the extreme conditions of a dry stream channel with major stormwater impacts during heavy rain storms. There was no distinct stream channel forming in 2017 and it was dry in May 2017, so replanting the monitoring plot with livestakes would not show stream stabilization results either way. The Plot will be dropped from monitoring and this area will be monitored through Monitoring Plot #4 vegetation stem counts. Martin Marietta — Bonds Quarry Stream Relocation Report of Findings — Monitoring Report Year Four October 2017 Page 9 E McGill ASS0CIATES Channel Stability The photodocumentation of the project stream channel was taken in May 2017 and can be seen compared with the As -Built photos in Appendix C. Each of the five permanent cross-sections were surveyed and compared to the As -built surveys. Survey results can be seen in tables in Appendix E. Base flows were lower in May 2017 in the lower stream reaches, but were consistent in the upper reaches. Normal rainfall had been experienced in the region within the past week. A computational error in the stream classification calculations were discovered this year and corrections were made going back to 2015 table results. Cross Section #1: riffle has stabilized over the 4 years of monitoring with little changes to stream characteristics. It is a shallow stream at this point but generally has perennial flow and shows good vegetation growth along the streambank as shown in the cross section photograph. The entrenchment ratio has decreased to a stable value. The cross section is in an area of heavy rooted vegetation and is in a stable configuration for the stream flows. Cross Section #2: Stream channel thalweg has shifted to the right from previous years. Banks are stable as shown in the photograph of the cross section. Some aggradation has occurred, primarily from the vegetative growth along the stream channel. The profile, depth and bankfull width has remained fairly constant over the monitoring period. Entrenchment ratio is low and the stream is connected to the floodplain. Depth is low and there is still perennial flow at this monitoring point in the stream channel. Cross Section #3: The graph shows a fairly stable dimension over the four years with only minimal changes in the survey. Bottom and right bank shows increased sediment deposition, but also increased depth and bankfull area. Entrenchment ratio has increased to moderately entrenched. There is perennial flow at this section of the stream and vegetation is well established as shown in the cross section photograph. This site may be moving to a pool condition as shown by the mean depth for this small stream. Cross Section #4: This site is in the section of the stream that is intermittent flow or dry except during rain events. Vegetation growth is minimal along the streambank due to the dry and rocky conditions. The channel has more characteristics of a stormwater conveyance channel than a stream. Survey graph shows a stable dimension over the years since the As Built — the cross section has stabilized at a slightly deeper and wider cross section and has remained consistent over the years. The channel is moderately entrenched and has been since construction in 2011. Cross Section #5: This station was completely reset in 2016 as construction in early 2016 regraded the streambank and floodplain topography changed drastically. This section of the stream is dry except during rain events. The new As Built condition has a wider floodplain, bankfull area, bankfull width while the depth of the dry channel is low. The site is showing none of the problems seen in past reports (headcut, bank erosion). Results can be seen in the table in Appendix E. Vegetation is beginning to recover and stabilize the area. Martin Marietta — Bonds Quarry Stream Relocation Report of Findings — Monitoring Report Year Four October 2017 Page 10 E, McGill ASSOC IAT ES Cross Section #6 Pool — This cross section was dropped in 2016 after the construction of a new floodplain/stream channel in the lower reach of the project. This was removed as no pool is forming in the new channel, and the area is moving more towards a wetland complex. The stability will be monitored in this area using Cross Section #5. Problem Areas This stream is located in a problematic environment. The channel was constructed in an area that was reduced in elevation by 20;-30', removing the top soil and much of the overlaying soils. It was constructed in saprolite, subsurface soils with large amounts of pit gravel and shale. This soil tends to erode severely if disturbed by any digging activities. The stream flow is intermittent near the beginning of the project and dries out as it flows downstream until it is a dry channel except during rain events. The source of the stream is mixed woods and commercial areas, with large amounts of impervious cover that leads to flashy streamflow events. After major bank erosion occurred in 2013, a stormwater detention basin was installed separate from this project to minimize these extreme events. The growth of vegetation along the stream channel was good in areas where there is flow most of the year, and poor in sections where there is no flow. Traditional riparian vegetation has not established along the stream channel except in the upper sections — and most of that was within the stream channel itself. Steps have been taken over the years to address these problems. In Monitoring Year 4, the remaining problem areas are as noted: • Streambank Erosion, headcutting and lack of vegetation between Station 43+50 and 47+00 (Close out as a problem area) • Exposed bedrock in streambank at Station 15+00 • Failure at a cross vane at Station 18+75 • Streambank erosion at Station 20+20 • Streambank erosion at Station 20+82 • Slow growth of vegetation in the project area These are being tracked and assessed. The total length of the areas compared with the full project length are a small percentage and with continued improvement, reducing in size each year (Figure 6). This year the lengths equaled 350 If. The majority of the length is in the lower section that was completely regraded (300 If) and is stable now. The remaining 501f of unstable streambank is only I% of the total stream relocation length. The problem areas are as follows: Stations 43+50 to 47+00 (Lower 300 If) The stream bank erosion at the end of the project appeared early after construction and was a known problem area with no control over the major factors (flood events from upstream and flooding of the Rocky River up into the UTA floodplain, little to no flow at other times of the Martin Marietta — Bonds Quarry Stream Relocation McGill Report of Findings —Monitoring Report Year Four October 2017 A S S O CI A I' E S Page 11 Area # Stream Stabilization Summary Total Length of Stream - 4,735' Areas of Concern Stabilization Area #1 - 26' (Station 14+99 thru 15+25) Stabilization Area #2 - 8' (Station 18+72 thru 18+80) Stabilization Area #3 - 24' (Station 20+10 thru 20+34) Stabilization Area #4 - 24' (Station 20+82 thru 21+06) Total Length of Concern Areas - 82' Repair Areas Repair Area #5 - 366' (Station 42+55 thru 46+21) Total Length of Repair Areas - 366' 0' 150' 300' 450' 600' I I I I I Scale — 1"=300' Area # Dee�_C ove Dvc �l s o N u ct It J s s 3 8 g 8 8 g 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 Area #38� Area #4 Area # Figure 6 - Problem Area Locations UTA Paar 17 S Aoa23 `5�w o Site w B N"y b Vicinity Map No Scale Martin Marietta Bonds Quarry Stream Relocation As-Builts Date: 9-8-17 year). There was downcutting of the channel, and erosion of the streambank impacting all streambank vegetation that was planted along the stream channel. After many different design/repairs were considered, an upstream off stream stormwater control basin was installed to manage peak flows. Then Martin Marietta regraded the whole lower 300' section, expanded the floodplain in 2016 and reconnected the stream to the expanded floodplain to allow for more area for flood waters to spread out. This would mimic the old stream channel connection to the Rocky River where a healthy wetland had developed and buffered the flood events both from UTA and the Rocky River. 2015 Photo of lower section 2016 Photo of Lower Section 2017 Photo of Lower Section The area has been replanted with tree species and native species are also showing growth that adds to the stabilization of the area. There is no sign of new erosion in the section. Old channels are dry for most of the year except during rain events. The area should be monitored to ensure vegetation gets established, at least as much as is allowed under the major power lines and over the sewer right of way. This area will no longer be tracked under problem areas as a separate section after this year.

McGill ASSOCIATES Station 15+00 2016 Right bank Station 15+00 2016 Looking at left bank Station 15+00 2017 Station 15+00 looking at right bank The size and dimension of this problem area has remained constant. The exposed bedrock provides grade control on river right. Vegetation has continued to expand on the eroded bank on river right and vegetation on river left has remained well established. The total length of rock exposure/streambank erosion is 24 linear feet. The problem area will be monitored, but has not expanded in size over the past few years. No remediation is recommended except to monitor vegetation growth in the area.

McGill ASSOCIATES Station 18+75 2016 Cross Vane 18+75 2017 Cross Vane 18+75 There has been no change in size or dimension of the eroded area in the past years. There is more vegetative growth on the exposed bank on stream left which will help to stabilize the area. The area of unstable streambank is 8 if in length. There is pit gravel and shale at this drop, providing Grade control. Last year the Longitudinal Profile has shown some changes over the past 2 years, but upstream and downstream profiles showed maintaining stable conditions. This section will be monitored for further changes and destabilization. Station 20+20 2016 Streambank Erosion 20+20 2017 Streambank Erosion at Station 20+20 As shown in the photograph, the section has maintained the previous condition and is showing some deposition of material in the channel. The total length of the stream bank erosion is 24 linear feet. There is bedrock on stream right providing some bed control. The vegetation has continued to increase coverage with more upland species, aiding in the stabilization of this section. No remediation is recommended at this time. Martin Marietta — Bonds Quarry Stream Relocation Report of Findings — Monitoring Report Year Four October 2017 Page 15 E, McGill ASSOCIA rES Station 20+82 2017 Streambank Erosion 20+82 This streambank erosion on river left was another location created in the flood of 2013. There is bedrock exposure on river right providing grade control. No further streambank erosion has been observed during the monitoring surveys and vegetation is beginning to stabilize the bank. The total length of this streambank exposure is 24 linear feet. This site will be monitored for further erosion and documented for stabilization. This site was not measured in previous years but was added to the problem areas for monitoring in 2017. Vegetation Stabilization in Buffer This has been noted and discussed in monitoring reports since the first year. This year we noted better planted and volunteer growth of species such as white pine, yellow poplar and eastern false willow. The herbaceous ground cover is shifting in species from lespedeza to more native species like dog fennel, blackberry, goldenrod, and aster family. The soil cover is building up over the exposed pea gravel and is able to support more native vegetation. Most of the vegetation problems in the past were due to planting riparian species where there was no hydrology to support those species. Better results have been noted as the project ages with upslope vegetation and native volunteers from seeds. As can be seen in the photographs of the stream channel and buffer, where there is more consistent water flow in the channel, the riparian vegetation has done extremely well. This can be monitored through photodocumentation and addressed as needed with additional plantings. Future Sampling Martin Marietta proposes that these problem areas be the focus of future monitoring efforts and stabilization activities. Based on the successful relocation and stabilization of most of the rest of the stream channel, Martin Marietta would like to reduce the total amount of stream monitoring for this project. This would allow Martin Marietta to concentrate on the sections of the stream Martin Marietta — Bonds Quarry Stream Relocation E McGill Report of Findings —Monitoring Report Year Four October 2017 ASSOCIATES Page 16 that still need continued surveillance and active stabilization efforts going forward in time. Future monitoring would include photodocumentation of project stability and vegetative growth, profile and cross section surveys at the problem areas, and streambank erosion monitoring.
