delivery stream and wetland restoration project for the North Carolina Ecosystem Enhancement Program (NCEEP) in Rockingham County, NC The stream area, hereafter referred to as the Stream Site, is located on the southeastern side of Reidsville along Irvin and Little Troublesome Creeks The wetland area, hereafter referred to as the Wetland Site, is located approximately four (4) miles southeast of the Stream Site and is also adjacent to Little Troublesome Creek The Stream Site is located south of Turner Road, east of the intersection of Turner Road and Way Street in the City of Reidsville, North Carolina The Wetland Site is located approximately 3,000 feet southwest of the intersection of NC Highway 150 and Mizpah Church Road, south of the City of Reidsville Little Troublesome Creek is located within the Haw River watershed (North Carolina Division of Water Quality (NCDWQ) Subbasin 03- 06 -01) of the Cape Fear River Basin (Hydrologic Unit 03030002010030) The Stream Site is located in a mature bottomland hardwood forest within a 34 5 -acre tract owned by Wildlands Little Troublesome Creek Holdings, LLC A conservation easement has been recorded on 33 acres of the tract (Deed Book 1411, Page Number 2458) Project streams reaches consist of Irvin Creek reach 1 and 2, Little Troublesome Creek, and UT1 as shown in Figure 2a The wetland portion of the Little Troublesome Creek project is located within a tract of land owned by Jerry Apple A conservation easement has been recorded on the 19 -acre project area within the Apple tract (Deed Book 1412, Page Number 1685) Project wetland areas consist of one (1) wetland (RW1) as shown in Figure 2b Little Troublesome Creek (NCDWQ Index No 16 -7), which is the main creek on the project site, has been classified as Class C, NSW waters Class C waters are protected for secondary recreation, fishing, wildlife, fish and aquatic life propagation and survival, agriculture, and other uses The Nutrient Sensitive Waters (NSW) classification is a supplemental classification for waters that are subject to excessive growth of microscopic or macroscopic vegetation and therefore need nutrient management Directions and a map of the Site are provided in Figure 1 11 Project Goals and Objectives Prior to construction activities, the most significant watershed stressors identified during the technical assessment were stream bank erosion and instability Other stressors included declining aquatic habitat, loss of forest, degraded riparian buffers, loss of wetlands, lack of urban stormwater detention, and water quality problems related to increased sediment and nutrient loadings As a result of the aforementioned stressors, the Stream Site and Wetland Site had poor water quality due to sediment pollution and poor habitat due to lack of riparian and wetland vegetation In particular, the Stream Site lacked stable streambank vegetation despite being surrounded by mature vegetation The Stream Site also lacked in- stream bed diversity and exhibited unstable geomorphic conditions Table 4 in Appendix 1 and Tables 10a, 10b, and 10c in Appendix 4 present the pre - restoration conditions in detail The primary objectives of the project were to stabilize highly eroding stream banks, reconnect streams to their historic floodplain, improve wetland hydrology and function, reduce nutrient levels, sediment input, and water temperature, increase dissolved oxygen concentrations, create appropriate in- stream and terrestrial habitat, and decrease channel velocities These objectives were achieved by restoring 4,988 linear feet (LF) of perennial stream channel, and restoring, enhancing, and creating 18 0 acres of riparian wetland The Stream Site and Wetland Site riparian areas were also planted to stabilize streambanks, improve habitat, and protect water quality The following primary project goals (measured) were established in the project Mitigation Plan (2011) to address the effects from watershed and project site stressors ON Little Troublesome Creek Mitigation Site Monitoring Year 2 Annual Report —FINAL Page 1 • Stabilize stream dimensions; • Stabilize stream pattern and profile; • Establish proper substrate distribution throughout stream; • Establish wetland hydrology for restored wetlands; and • Restore native vegetation throughout wetlands and buffer zones. The following secondary project goals (unmeasured) were established in the project Mitigation Plan (2011) to address the effects from watershed and project site stressors: • Decrease nutrient and urban runoff pollutant levels; • Decrease sediment input; • Decrease water temperature and increase dissolved oxygen levels; • Create appropriate in- stream habitat; • Create appropriate terrestrial habitat; and • Decrease channel velocities. The following project objectives were established to meet these primary and secondary goals: • Riffle cross - sections of the restoration and enhancement reaches were constructed to remain stable and will show little change in bankfull area, maximum depth ratio, and width - to -depth ratio over time. • The project was constructed so that the bedform features of the restoration reaches will remain stable overtime. This includes riffles that will remain steeper and shallower than the pools and pools that are deep with flat water surface slopes. The relative percentage of riffles and pools will not change significantly over time. Banks will be constructed so that bank height ratios will remain very near to 1.0 for nearly all of the restoration reaches. • Stream substrate will remain coarse in the riffles and finer in the pools. • A free groundwater surface will be present within 12 inches of the ground surface in the restored wetland areas for 7 percent of the growing season measured on consecutive days under typical precipitation conditions. • Native vegetation appropriate for the wetland and riparian buffer zones were planted throughout both the Wetland and Stream Sites. The planted trees will become well established and survival criteria will be met. • Off -site nutrient input will be absorbed on -site by filtering flood flows through restored floodplain areas and wetlands, where flood flows can disperse through native vegetation and be captured in vernal pools. Increased surface water residency time will provide contact treatment time and groundwater recharge potential. • Sediment input from eroding stream banks was reduced by installing bioengineering and in- stream structures while creating a stable channel form using geomorphic design principles. Sediment from off -site sources will be captured by deposition on restored floodplain areas where native vegetation will slow overland flow velocities. • Restored riffle /step -pool sequences where distinct points of re- aeration can occur will allow for oxygen levels to be maintained in the perennial reaches. Creation of deep pool zones will lower temperature, helping to maintain dissolved oxygen concentrations. Establishment and maintenance of riparian buffers will create long -term shading of the channel flow to minimize thermal heating. • A channel form that includes riffle /pool sequences and gravel and cobble zones of macroinvertebrate habitat for fish was created. Large woody debris, rock structures, root Little Troublesome Creek Mitigation Site Monitoring Year 2 Annual Report —FINAL Page 2 wads, and native stream bank vegetation were introduced to substantially increase habitat value • Adjacent buffer areas were restored by removing invasive vegetation and planting native vegetation These areas will be allowed to receive more regular and inundating flows Riparian wetland areas were restored and enhanced to provide wetland habitat • By allowing for more overbank flooding and by increasing channel roughness, local channel velocities can be reduced This will allow for less bank shear stress, formation of refuge zones during large storm events and zonal sorting of depositional material 12 Monitoring Year 2 Data Assessment The final restoration plan was submitted and accepted by NCEEP in June 2011 Construction activities were completed by Fluvial Solutions in May 2012 The baseline monitoring and as -built survey (MY -0) were completed between April and May 2012 Annual monitoring will be conducted on the Stream Site fora total of five (5) years Annual monitoring will be conducted on the Wetland Site for a total of seven (7) years The close -out for both the Stream Site and Wetland Site is anticipated to commence in 2019 Annual monitoring and quarterly site visits were conducted during monitoring year 2 (MY -2) to assess the condition of the project The stream and wetland mitigation success criteria for the Site follow the approved success criteria presented in the Little Troublesome Mitigation Plan (2011) 12 1 Vegetative Assessment Vegetation assessments were conducted following the Carolina Vegetation Survey (CVS) Level 2 Protocol for Recording Vegetation (Lee et al, 2008) A total of 35 vegetation plots were established during the baseline monitoring within the project easement areas (22 at the Wetland Site, 13 at the Stream Site) using standard 10 meter by 10 meter vegetation monitoring plots Due to the narrow planted corridor along UT1, vegetation plots were not established Instead, a visual assessment of the planted corridor is used to evaluate vegetation growth success The final vegetative success criteria will be the survival of 260 planted stems per acre in the riparian corridor of the Stream Site at the end of MY -5, and 200 planted stems per acre within the Wetland Site at the end of year seven monitoring (MY -7) The interim measure of vegetative success for the Stream and Wetland Sites will be the survival of at least 320 planted stems per acre at the end of the third monitoring year (MY -3) The MY -2 vegetation survey on the Wetland Site resulted in an average stem density of 532 stems per acre, which is greater than the interim requirement of 320 stems /acre and approximately 24% less than the baseline (MY -0) density recorded (701 stems /acre) There was an average of 13 stems per plot compared to 17 stems per plot during MY -0 for the Wetland Site The average stem density on the Stream Site was 781 stems /acre, which is also greater than the interim requirement, but approximately 18% less than the baseline density recorded (953 stems /acre) There was an average of 19 stems per plot compared to 24 stems per plot in MY -0 for the Stream Site A total of 33 plots are on track to meet the interim success criteria of 320 stems per acre required for MY -3 Vegetation plots 16 and 17 within the Wetland Site resulted in fewer surviving stems than required to reach the interim success criteria, however the plots currently exceed the final vegetative success criteria of 200 stems per acre density for the Wetland Site in MY -7 Invasive species have been identified onsite at the Stream Site, including Kudzu, Murdannia, Japanese Stilt Grass, Multiflora Rose, Air Potato, and Morning Glory However, the presence of these species does not appear to be affecting the survivability of planted stems Please refer to Appendix 3 for vegetation summary tables and raw data tables and Appendix 2 for vegetation plot photographs and the vegetation condition assessment table Oft Little Troublesome Creek Mitigation Site Monitoring Year 2 Annual Report —FINAL Page 3 Maintenance Plan The need for supplemental plantings will be evaluated in Winter 2013/2014. Wildlands will re- evaluate the low stem density areas from the MY -2 vegetation survey during the winter 2013 and determine where and if supplemental planting is needed on the Site. Maintenance of invasive vegetation areas will be assessed in Winter 2013/2014 and will be selectively treated with herbicide in the Spring 2014. Follow up treatments will be conducted annually as necessary to control their spread and dominance. 1.2.2 Stream Assessment Morphological surveys for the MY -2 were conducted in June 2013. All streams within the Site met the success criteria for MY -2. Please refer to Appendix 2 for the visual assessment table, current condition plan view (CCPV), and photographs and Appendix 4 for morphological data and plots. Riffle cross - sections surveyed along the restoration reaches have met success criteria for MY -2. The cross - sections appear stable and show little to no change in the bankfull area, maximum depth ratio, or width -to -depth ratio. All surveyed riffle cross - sections fell within the parameters defined for channels of the appropriate Rosgen stream type. The surveyed longitudinal profile data for the stream restoration reaches illustrates that the bedform features are maintaining lateral and vertical stability. The riffles are remaining steeper and shallower than the pools, while the pools are remaining deeper than riffles and maintaining flat water surface slopes. The longitudinal profiles show that the bank height ratios remain very near to 1.0 for all of the restoration reaches. Deposition within pools was documented in the longitudinal profile along UT1. The deposition is not affecting channel stability but will be monitored. In- stream structures, such as root wads used to enhance channel habitat and stability on the outside bank of meander bends are providing stability and habitat as designed. Pattern data will only be completed in MY -5 if there are indicators from the profile or cross - sections that significant geomorphic adjustments have occurred. No changes were observed that indicated a change in the radius of curvature or channel belt width; therefore, pattern data is not included in the MY -2 report. Substrate materials in the restoration reaches indicate a progression toward and the maintenance of coarser materials in the riffle features and smaller particles in the pool features. 1.2.3 Hydrology Assessment At the end of the MY -5 period, two (2) or more bankfull events must occur in separate years within the restoration reach. Bankfull events were recorded on Irvin Creek, Little Troublesome Creek, and UT1 by crest gage or onsite observations (wrack lines) during the MY -2 data collection. Please refer to Appendix 5 to review the hydrologic data. 1.2.4 Wetland Assessment Groundwater monitoring gages were established throughout the wetland restoration, enhancement, and creation areas on the Wetland Site. The gages were installed at appropriate locations so that the data collected will provide an indication of groundwater levels throughout the wetland project area. A total of eight (8) groundwater gages were installed. According to local WETS station in Eden, NC, the growing season in Rockingham County runs from March 25th to November 6th (226 days). Wildlands installed two (2) soil temperature loggers, one (1) within each wetland, to collect additional growing season data. These probes can be used to better define the growing season using the threshold soil temperature of 41 degrees or higher measured at a depth of 12 inches (USACE, 2010). The probes indicate a longer growing season than that defined for Little Troublesome Creek Mitigation Site Page 4 Monitoring Year 2 Annual Report —FINAL Rockingham County by the WETS station data. A barotroll logger and a rain gage were also installed onsite. All monitoring gages were downloaded on a quarterly basis and will be maintained on an as needed basis. The onsite rain gage appeared to be malfunctioning during part the growing season, therefore daily and monthly rainfall totals beginning on May 24 are reported from a nearby weather monitoring station (REID) at Upper Piedmont Research Station, Reidsville NC, part of the ECONet /CRONOS database maintained by the State Climate Office of North Carolina. Monitoring gage locations are depicted on the CCPV maps in Appendix 2. The success criteria for wetland hydrology is to have a free groundwater surface within 12 inches of the ground surface for 7 percent of the growing season, which is measured on consecutive days under typical precipitation conditions. An onsite rainfall gage recorded 16.61 inches of precipitation from January through May 2013. This is lower than the historic precipitation average of 20.02 inches from January through May collected at nearby weather station Reidsville 2 NW, NC7202 between 1971 and 2000 (USDA 2002). In addition, a nearby active weather station (REID) recorded 38.45 inches from January through October of 2013, which is more than the historic precipitation average of 31.34 inches collected at Reidsville 2 NW NC7202 (SCONC 2013, USDA 2002). All of the groundwater monitoring gages met the annual wetland hydrology success criteria. Please refer to Appendix 5 for wetland hydrology data and plots. 1.3 Monitoring Year 2 Summary Overall, all streams within the Site are stable and functioning as designed. Of the 35 vegetation plots, 33 met the success criteria required for MY -2 as seen in the CCPV. There has been at least two (2) bankfull events recorded along each restored project reach since construction commenced, therefore, the MY5 hydrology attainment requirement has been met for the Site. Currently, all groundwater gages are meeting success criteria for wetland hydrology. Summary information /data related to the 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 Mitigation Plan documents available on NCEEP's website. All raw data supporting the tables and figures in the appendices is available from NCEEP upon request. 2.0 Methodology Geomorphic data was collected followed the standards outlined in The Stream Channel Reference Site: An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in the Stream Restoration: A Natural Channel Design Handbook (Doll et al., 2003). Longitudinal and cross - sectional data were collected using a total station and were georeferenced. Reach wide pebble counts were conducted along each restored reach for channel classification. Cross - section substrate analyses conducted in each surveyed riffle followed the 100 count wetted perimeter methodology. Subpavement samples were collected at each surveyed riffle cross - section and processed in an outsourced lab. All CCPV mapping was recorded using a Trimble handheld GPS with sub -meter accuracy and processed using was Pathfinder and ArcView. Crest gages were installed in surveyed riffle cross - sections and monitored quarterly. Hydrology attainment installation and monitoring methods are in accordance with the United States Army Corps of Engineers guidelines (2003). Vegetation monitoring protocols followed the Carolina Vegetation Survey - NCEEP Level 2 Protocol (Lee et al., 2008). ktp Little Troublesome Creek Mitigation Site Page 5 Monitoring Year 2 Annual Report —FINAL Yl 3.0 References Doll, B A, Grabow, G L, Hall, K A, Halley, J, Harman, W A, Jennings, G D, and Wise, D E, 2003 Stream Restoration A Natural Channel Design Handbook , j Harrelson, Cheryl C, Rawlins, C L, Potyondy, John P 1994 Stream Channel Reference Sites An Illustrated Guide to Field Technique Gen Tech Rep RM -245 Fort Collins, CO U S Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station 61 p Lee, Michael T, Peet, Robert K, Steven D, Wentworth, Thomas R (2008) CVS -EEP Protocol for Recording Vegetation Version 4 0 Retrieved from http //www nceep net /business/ monitoring /veg /datasheets htm Rosgen, D L 1994 A classification of natural rivers Catena 22 169 -199 Rosgen, D L 1996 Applied River Morphology Pagosa Springs, CO Wildland Hydrology Books Rosgen, D L 1997 A Geomorphological Approach to Restoration of Incised Rivers Proceedings of the Conference on Management of Landscapes Disturbed by Channel Incision Center For Computational Hydroscience and Bioengineering, Oxford Campus, University of Mississippi, Pages 12 -22 Schafale, M P and A S Weakley 1990 Classification of the Natural Communities of North Carolina, 3rd approx North Carolina Natural Heritage Program, Raleigh, North Carolina State Climate Office of North Carolina (SCONC) 2013 CRONOS Database ECONet weather station at Upper Piedmont Research Station (REID), in Reidsville, NC http //nc- climate ncsu edu /cronos ?station =REID &temporal =daily ' -J United States Army Corps of Engineers (USACE), 2003 Stream Mitigation Guidelines USACE, NCDENR- DWO, USEPA, NCWRC United States Army Corps of Engineers (USACE) 2010 Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual Eastern Mountains and Piedmont Region (ERDC /EL TR -10- 9) U S Army Engineer Research and Development Center, Vicksburg, MS United States Department of Agriculture (USDA) 2002 Natural Resources Conservation Service, Climate Information for Catawba County, NC (1971 -2000) WETS Station Reidsville NW, NC7202 http //www wcc nres usda gov /ftpref/ support/climate /wetlands /nc/37157 txt United States Geological Survey (USGS), 1998 North Carolina Geology http // http / /www geology enr state nc us /usgs /carolma htm Wildlands Engineering, Inc (2011) Little Troublesome Mitigation Site Mitigation Plan NCEEP, Raleigh, NC ON Little Troublesome Creek Mitigation Site Monitoring Year 2 Annual Report —FINAL Page 6 APPENDIX 1.
