The corridors provide connectivity to a diversity of habitats including mature forest, early successional forest, stream -side forest, riparian wetlands, and uplands. • Providing an educational benefit to children who can utilize the planned pedestrian footpath crossing the floodplain, and can view the stream channel from adjacent terraces where schools are located. 1.2 Background Summary The North Carolina Ecosystem Enhancement Program (EEP) has completed restoration of 2,715 linear feet of stream and enhanced 8.7 acres of riparian wetland at the Site to assist in fulfilling stream and wetland mitigation goals in the area. The Site is located in northwest Cabarrus County approximately 6 miles southwest of the town of Kannapolis (Figure 1). The Site has a latitude and longitude of 035° 25' 34.52" N and 080° 44' 25.53" W. The Site is situated in the northeast quadrant of the intersection of Harris Road and the Rocky River, between Harris Middle School and Odell Elementary School, approximately 1.5 miles south of Highway 73. ' C Page 2 Engineering ELP IMS No. 92383 U I Rock\ River - Harris Road Middle C'abarruS County. North Carolina PEAR TWO MONITORINCI REPORT Nov ember 201 3 The Site is located within United States Geological Survey (USGS) Hydrologic Unit (HU) and Targeted Local Watershed 03040105010010 (North Carolina Division of Water Quality [NCDWQ] Subbasin 03- 07 -11) of the Yadkin -Pee Dee River Basin, and will service the USGS 8 -digit Cataloging Unit (CU) 03040105. The Site is currently owned by Cabarrus County and the State of North Carolina holds the conservation easement on the property. 1.3 Vegetation Bare root and live stake plantings are surviving well across the Site with an average of 364 planted stems per acre surviving after Year 2. Plots 1, 2, 3, 5, 6, 11, 12, 13 and 14 of 14 vegetation plots are exceeding success criteria of at least 320 stems per acre. All of the plots contain 242 or greater stems per acre surviving after Year 2. Plot 4, 9 and 10 have greater than 360 stems per acre when including natural recruits. Plot 7 was affected by a beaver dam that was located immediately adjacent to the plot during Year 1 monitoring; however, the dam has been removed. APHIS was previously contracted to conduct monthly inspections at the Site to ensure beaver are controlled throughout the monitoring phase of the project. Due to lack of recent activity and cost, APHIS site inspections for beaver activity are now quarterly. Plot 8 is located on a terrace slope along the southern boundary of the Site. This area appears to be drier than other areas at the Site, which may be contributing to the poor survival of planted stems in Plot 8. Approximately half of Plot 10 is also located along a terrace side slope and appears somewhat drier than other areas. Encroachment has occurred within Plot 10. It appears mowers have entered the easement /plot and taken out a vegetation plot stake. Additional plantings are not recommended at this time because natural recruitment of character tree species is anticipated over the course of the monitoring period and the areas exhibiting poor survivability are relatively small. A small cluster of Sericea lespedeza (Lespedeza cuneata) was observed within Plot 9. Plot 9 is located near Moss Farm Street and a sewer easement that crosses UT Rocky River at the beginning of the project making this area susceptible to encroachment of invasive species. Plot 9 is currently not exceeding success criteria goals with 283 planted stems per acre surviving after Year 2; however, the stem count is 567 with natural recruits. EEP does not typically treat lespedeza during invasive species treatments; however, if the population continues to have a detrimental effect on the plot and surrounding area in monitoring Year 3, EEP will reassess. 1.4 Stream Stability UT Rocky River appears to be stable and functioning as designed. The area formerly affected by the beaver dam is recovering. There is no evidence of trends toward significant change in channel dimension or pattern. Approximately 140 feet of the profile (Station H +78 — 13 +18) around Cross Section 1 show evidence of minor deposition most likely due to a slightly lower slope. Cross - sectional data indicates that the channel has experienced little change in dimension, with the exception of Cross Section 6. Cross Section 6 has continued to deepen in comparison with baseline and Year 1 conditions, resulting in a larger cross sectional area and smaller width to depth ratio. Scour at Cross Section 6 is likely a result of increased shear stress caused by the Page 3 Engineering EEP IMS No. 92383 UT Rocky River — Harris Road Middle Cabarrus County, North Carolina YEAR TWO MONITORING REPORT November 2013 beaver dam formerly located approximately 50 feet upstream. The beaver dam raised the water surface elevation above bankfull and increased the average water surface slope through this section. Profile data also depicts scour in the channel bed downstream of the beaver dam. Cross Section 6 appears to currently function as a pool in the system and will likely continue to function as a pool in the future. Profile plots depict minimal shifting and deepening of pools throughout the reach. Some shifting is expected in sand bed channels, where the bed form is in constant flux and pools adjust their depths during most storm events. Sediment deposited immediately upstream of the beaver dam is flushing out now that the beaver dam has been removed. The percentage of riffles and pools throughout the reach has continued to change slightly from baseline conditions. Year 2 data depicts riffles to account for 28 percent (compared to 38 and 43 percent at Year 1 and baseline respectively) and pools to account for 72 percent (compared to 62 and 57 percent at Year 1 and baseline respectively). The backwater effect upstream of the beaver dam and the scour downstream of the beaver dam are the primary reasons for the change in riffle /pool percentages in Year 1. The channel is beginning to show some signs of reforming a riffle and pool sequence upstream of the old beaver dam; however, the Year 2 survey was taken within a month from the beaver dam removal and more time is needed to allow the channel to recover. The riffle sections affected by backwater from the beaver dam are expected to regain function once the stream has had time to recover from the beaver dam. The section downstream of the beaver dam is designed to function as a step -pool system to step the invert of UT Rocky River down to the invert of Rocky River. During Year 1 and 2, the pools between the log steps have enlarged, but the stream remains stable and is performing as intended. All structures are stable and maintaining grade control except the structure at station 35 +80 which is showing erosion along the right arm. Table 5, Visual Stream Morphology Stability Assessment, details 97 percent of the stream bed as stable, performing as intended for Year 2 Monitoring. One minor headcut was noted at station 14 +20 (Figure 3.16). Nine areas along the bank are experiencing erosion and are depicted on the Current Conditions Plan View (CCPV) located in Appendix B. Photos of each problem area are also included in Appendix B. Approximately 40 feet of the right bank near station 14 +50 has stabilized since the vertical bank was observed during Year 1 Monitoring. The right bank at station 14 +90 has little to no vegetation (Figure 3.17). Approximately 20 feet of the left bank near station 20 +90 has scoured allowing higher flows to migrate into the floodplain (Figure 3.18). The erosion occurs just upstream of a log sill, but the stream has not fully migrated around the log sill at this time. Woody and herbaceous vegetation in the floodplain is slowing the progression of erosion. This area will be watched closely and if the stream continues to migrate around the log sill corrective actions will be recommended to repair the area. The log sill at 20 +90 appears to be piping at low flow but is still holding grade. Immediately downstream of the log sill near station 20 +90, the right bank has scoured for approximately 15 feet (Figure 3.19). A rootwad was placed in this bank to stabilize the log sill Ai Page 4 Engineering EEP IMS No. 92383 UT Rocky River— Barris Road Middle Cabai'rLIS County, North Carolina YEAR TNVO MONITORING REPORT November 2013 and it appears that the erosion has occurred along the trunk of the rootwad. Due to the relatively small size of this eroded area and the stability of the bank behind the rootwad, corrective actions are not recommended at this time. The double step log cross vane at 22 +30 has eroded on the right bank of the structure and is piping around the side of the header log (Figure 3.20). Corrective actions are not recommended at this time. The beaver dam observed near station 33 +30 during Year 1 monitoring was removed during January and February of 2013. Backwater from the beaver dam was observed as far upstream as station 30 +00. The beaver dam has not had a significant impact on the stability of the stream (Figure 3.21). EEP had previously contracted APHIS to conduct monthly inspections to prevent re- colonization through the monitoring period. Due to the lack of recent activity and cost, APHIS site inspections for beaver activity are now quarterly on the site. Minor bank erosion has occurred at station 34 +25 near vegetation plot 13 (Figure 3.22). Major bank erosion has been noted around the meander bend at station 35 +80 upstream of the log cross vane's right arm (Figure 3.24). This area will be watched closely. EEP plans to plant additional live stakes in these areas during the upcoming dormant season. The site has experienced several bankfull flows throughout the first and second monitoring years. Crest gauges installed on -site were inspected on March 8, 2012; October 4, 2012; March 20, 2013 and September 24, 2013. The crest gauges revealed that a bankfull event occurred at least four times during Year 1 and 2 monitoring. (Table 13). Additional overbank evidence includes debris lines and vegetation bent in the downstream direction. Evidence of bankfull events can be found in Appendix E. 1.5 Wetlands Existing wetlands at the Site were enhanced by removing exotic vegetation and planting native species. All vegetation plots located within wetland areas are exceeding success criteria, with the exception of Plot 7 which was affected by the beaver dam during Year 1 monitoring and Plot 9 which is affected by the dominance of lespedeza in the upland portion of the plot. Section 1.3 provides more details concerning vegetation at the Site. 1.6 Note A vehicular path was noted within the easement break around station 20 +00 during vegetation monitoring field work in August, 2013. EEP was immediately notified of the field observation. Summary information/data related to the occurrence of items and statistics related to performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the Baseline Monitoring Report (formerly Mitigation Plan) and in the ' CAAI;� Page 5 Engineering EEP IMS No. 92383 UT Rocky River - Harris Road Middle Cabanas County, North Carolina YEAR TWO MONITORING REPORT November 2013 Mitigation Plan (formerly the Restoration Plan) documents available on EEP's website. All raw data supporting the tables and figures in the appendices is available from EEP upon request. 2.0 METHODOLOGY The Year 1 and 2 monitoring surveys were completed using a Total Station. Each cross section was marked with two rebar monuments at their beginning and ending points. The rebar has been located vertically and horizontally in NAD 83 -State Plane. Surveying these monuments throughout the Site ensured proper orientation. The survey data was imported into MicroStation for verification. The longitudinal stationing was developed from total station data and compared with previous years' data to ensure consistent beginning and ending points. RIVERMorph and the Ohio Department of Natural Resources' "The Reference Reach Spreadsheet Version 4.3L" were used to analyze the profile and cross section data (Mecklenburg 2006). Tables and figures were created using Microsoft Excel. The channel is entirely a sand bed system; therefore, a pebble count was not conducted. Vegetation monitoring was completed using CVS level II methods, for 14, 100 square meter vegetation plots (Lee et al. 2006). The taxonomic standard for vegetation used for this document was Flora of the Southern and Mid - Atlantic States ( Weakley 2011). 3.0 REFERENCES Lee, Michael T., R. K. Peet, S. D. Roberts, and T. R.
