The SCMP project area is approximately 196.5 acres, located eleven miles northeast of the City of Rocky Mount in Edgecombe County, NC (35.999286°, -77.605591°). The SCMP is located within the 8-digit HUC 03020101, in the NC Department of Environmental Quality (NCDEQ) sub-basin 0302010108 (Swift Creek), within the Tar-Pamlico River Basin. The SCMP includes the restoration, enhancement, and permanent protection of five stream reaches totaling 8,890 linear feet of stream and the establishment of approximately 200-ft wide Tar-Pamlico riparian buffers totaling 14.86 acres, with 27.31 acres being permanently preserved. The SCMP also includes the re- establishment, enhancement, and preservation of 53.8 acres of riparian wetlands. The SCMP will provide significant ecological improvements and functional uplift through stream and aquatic habitat restoration and through decreasing nutrient and sediment loads within the watershed. The Year 2 monitoring report provides a project summary and Appendix A Table 1 provides a summary of project assets. Figures in Appendix B illustrate an overview and detailed inset of the project mitigation components. Monitoring Year 2 (MY2) activities occurred from September to November 2023. This report presents the data for MY2. The SCMP meets the MY2 success criteria for stream hydrology, stream pattern, profile, and dimension. The SCMP generally meets the MY2 success criteria for wetland hydrology. However, one well in Wetland 10 does not meet the success criteria for percent hydroperiod and two wells, one in Wetland 10 and one in Wetland 12, do not meet success criteria for consecutive days of saturation. The SCMP generally meets the MY2 success criteria for vegetation. However, five individual vegetation plots did not meet MY2 success criteria for stems per acres, and two individual vegetation plots did not meet success criteria for percent of dominant species. The stream restoration appears to be generally progressing towards success criteria. However, the headwater reach of SA continues to lack many aspects of headwater stream channel formation, and indicators of a defined channel are limited in the majority of the reach for SB. Based on these results, the SCMP generally is on trajectory to meet interim and final success criteria. However, adaptive management, including additional planting and monitoring, may have to be considered in areas of concern. For more information on the chronology of the project history and activity, refer to Appendix A, Table 2. Relevant project contact information is presented in the appendices in Appendix A, Table 2 and project background information is presented in Appendix A, Table 3. 1.2 PROJECT GOALS AND OBJECTIVES The SCMP will meet the goals and objectives described in the Swift Creek Final Approved Permittee Responsible Mitigation Plan (May 2019) and will address general restoration goals and opportunities outlined in the North Carolina Division of Mitigation Services (NC DMS) Tar-Pamlico River Basin River Basin Restoration Priorities (RBRP) (DEQ 2010). More specifically, watershed goals and management strategies will be met by: • Reducing sediment, soil erosion, turbidity, and nutrient inputs such as nitrogen and phosphorus to the Tar-Pamlico River Watershed. • Restoring, enhancing, preserving, and protecting headwater streams, wetlands, riparian buffers, and aquatic habitat functions. Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 5 • Improving riparian corridor management and targeting restoration of impacted streams and riparian buffer areas. To accomplish these plan-specific goals, the following objectives will be measured to document overall project success: • Promote wetland hydrology by raising channelized stream beds and filling drainage ditches; • Plant wetland areas with native tree species to restore the natural vegetative communities; • Reconstruct stream channels to have the appropriate slope, planform, and cross-sectional geometry for the region of the Coastal Plain in which the SCMP is located; • Size reconstructed stream channels to inundate adjacent floodplains and wetlands frequently; • Stabilize stream banks using bioengineering, natural channel design techniques, and grading to reduce bank angles and bank height; • Install in-stream structures and woody debris to promote aeration of water, create habitat, and influence the creation of bed forms commonly found in sand bed channels; • Restore riparian buffer areas with native tree species to stabilize channels, filter flood flows and runoff, and supplement wetland plantings; and • Remove a large acreage of land from agricultural production within the Mitigation Plan to further improving water quality. 1.3 MONITORING SCHEDULE AND REPORTING The SCMP will be monitored on a regular basis with physical inspections to occur a minimum of once annually throughout the seven-year post-construction monitoring period, or until performance standards are met. The measure of stream restoration success will be documented by bankfull flows and no change in stream channel classification. Sand bed channels are dynamic and minor adjustments to dimension and profile are expected. Wetland restoration success will be documented by hydrology. Site inspections and monitoring reports will also identify components and features that require routine maintenance or adaptive management. Tar River Land Conservancy (TRLC) is the easement holder and long-term steward noted in the PRMP. TRLC will be responsible for annual inspection of the SCMP after close-out of the monitoring period to ensure that restrictions in place required by the recorded Conservation Easement document are being upheld. 1.4 PROJECT SUCCESS CRITERIA The success criteria for the SCMP will follow approved performance standards and monitoring protocols from the final approved mitigation plan, which was developed in compliance with the USACE October 2016 Guidance, USACE Stream Mitigation Guidelines (April 2003 and October 2005), and the 2008 Compensatory Mitigation Final Rule. Vegetation plot data will be collected during monitoring years 0, 1, 2, 3, 5, and 7 and cross-section data will be collected during monitoring years 1, 2, 3, 5, and 7. Stream and wetland hydrology data and visual monitoring will be collected annually. Macroinvertebrate data will be collected in monitoring years 3, 5, and 7. Specific success criteria components and evaluation methods are described below. Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 6 1.4.1 SINGLE-THREAD STREAMS Stream Hydrology: Four separate bankfull flow events, occurring in separate years, must be documented on the restoration and enhancement reaches during monitoring years 1 through 7. Stream monitoring will continue until success criteria in the form of four bankfull events in separate years have been documented. Stream Profiles, Vertical Stability, and Floodplain Access: A longitudinal profile was collected as part of the as- built survey; however, longitudinal profile surveys will not be conducted during the seven-year monitoring period unless other indicators during the annual monitoring indicate a trend toward vertical and lateral instability. Migration of pools and bed forms is expected and does not require remedial action. Stream pattern and profile will be assessed visually as described below. Stream stability and floodplain access will be evaluated by measuring bank height ratio (BHR). Shallow section cross-sections on the restoration reaches should be stable and should show little change in bankfull area, maximum depth ratio and width-to-depth ratio. Shallow cross-sections should fall within the parameters defined for channels of the appropriate Rosgen stream type (when applicable). The BHR will not exceed 1.2 and the entrenchment ratio (ER) will be no less than 2.2 at any measured riffle cross-section. This standard only applies to restored reaches of the channel where BHRs were corrected through design and construction. Vertical stability will be evaluated with visual assessment and cross sections. Stream Horizontal Stability: Stream horizontal stability will be measured by cross-sections. Two permanently monumented cross-sections have been installed per 1,000 linear feet of stream restoration work and represent approximately 50 percent shallow/riffle and 50 percent pool areas within each restoration and enhancement reach. Each cross-section has been permanently marked with pins to establish its location. Cross-section surveys will be performed during monitoring years 1, 2, 3, 5, and 7 and will include points measured at all breaks in slope, including top of bank, bankfull, edge of water, and thalweg. It is important to note that in sand bed channels, pools and bed forms (ripples, dunes, etc.) may migrate over time as a natural function of the c hannel hydraulics. These sorts of bed changes may not constitute a trend towards instability or indicate a need for remedial actions. The BHR and ER at any measured riffle cross-section should not change by more than 10 percent from the baseline (as-built) condition during any given monitoring interval (e.g., no more than 10 percent between years 1 and 2, 2 and 3, 3 and 5, or 5 and 7). For example, if BHR is calculated to be 0.8 at a given cross section following monitoring year 1, acceptable BHR calculated for that cross section in monitoring year 2 would be 0.8 ± 0.08 (0.72 to 0.88). If any changes do occur, these changes will be evaluated to assess whether the stream channel is showing signs of instability. Indicators of instability include a vertically incising thalweg or eroding channel banks. Changes in the channel that indicate a movement toward stability or enhanced habitat include a decrease in the width-to-depth ratio in meandering channels or an increase in pool depth. Remedial action would not be taken if channel changes indicate a movement toward stability. Permanent photograph stations at each cross-section will document stability and channel evolution during the monitoring period. Photographs will be taken looking across channel, looking upstream, and looking downstream, showing as much of the banks and channel as possible. The survey tape will be centered in each photograph and the water line will be located near the lower edge. An effort will be made to consistently show the same photograph area in each subsequent monitoring event. Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 7 Streambed Material Condition and Stability: Pebble count procedures will not be conducted for this project due to the sand bed nature of the streams. 1.4.2 HEADWATER STREAMS Seasonal Flow: Under normal circumstances, surface water flow within the valley or crenulation will be documented to occur every year for at least 30 consecutive days during the seven-year monitoring period. Additional monitoring may be required if surface water flow c annot be documented due to abnormally dry conditions. Channel Formation: During monitoring years 1 through 4, a preponderance of evidence must demonstrate a concentration of flow indicative of channel formation within the topographic low -point of the valley or crenulation as documented by the following indicators: • Scour (indicating sediment transport by flowing water) • Sediment deposition (accumulations of sediment and/or formation of ripples) • Sediment sorting (sediment sorting indicated by grain-size distribution within primary flow path) • Multiple observed flow events (must be documented by gauge data and/or photographs) • Destruction of terrestrial vegetation • Presence of litter and debris • Wracking (deposits of drift material indicating surface water flow) • Vegetation matted down, bent, or absent (herbaceous or otherwise) • Leaf litter disturbed or washed away • During monitoring years 5 through 7, the stream must successfully meet the requirements above and in addition must demonstrate the development of stream bed and banks as documented by the following indicators: • Bed and banks (may include the formation of stream bed and banks, development of channel pattern such as meander bends and/or braiding at natural topographic breaks, woody debris, or plant root systems) • Natural line impressed on the bank (visible high-water mark) • Shelving (shelving of sediment depositions indicating transport) • Water staining (staining of rooted vegetation) • Change in plant community (transition to species adapted for flow or inundation for a long duration, including hydrophytes) • Changes in character of soil (texture and/or chroma changes when compared to the soils abutting the primary path of flow) 1.4.3 WETLANDS Wetland Hydrology: Hydroperiod ranges are based on the suggested wetland saturation thresholds for soils taxonomic groups. The predominant soils within the wetland restoration and enhancement areas consist of Roanoke soils. Therefore, the performance standard is that well data from the wetland enhancement areas indicate that groundwater is within 12 inches of the soil surface for seven percent target saturation period for monitoring years 1 and 2 and 10-12 percent for monitoring years 3 – 7 of the annual growing season during normal weather conditions. The growing season for the SCMP was taken from the National Weather Service Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 8 (NWS) Cooperative Observer Program (COOP) Station 318500, which is located in Tarboro, Edgecombe County. Based on this growing season, success will be achieved at the SCMP if the water table is within 12 inches of the soils surface for 17 consecutive days or more during the established growing season (March 21 to November 11, 235 days) for monitoring years 1 and 2 and a minimum of 23 consecutive days for monitoring years 3 – 7. Automated groundwater recording wells were installed in accordance with the techniques and standards described in the USACE’s “Technical Standard for Water-Table Monitoring of Potential Wetland Sites” (ERDC TN- WRAP-05-2, June 2005). An automated rain gauge has been installed to collect and record rainfall at the SCMP. The rain gauge incorporates a tipping-bucket design (at a 0.01-inch tipping interval) and records sufficient data to determine rainfall quantities, rates and duration. Rainfall data collected from the gauge will be correlated with local weather stations and compared to the National Resource Conservation Service (NRCS) Climate Analysis for Wetlands Tables (WETS tables) to determine if normal rainfall conditions exist during the monitoring period. The rain gauge will be downloaded during each site visit. If necessary, rainfall from the nearest weather station may be used to supplement data collected on-site if issues occur with the sampling equipment. 1.4.4 VEGETATION Vegetation monitoring will occur in monitoring years 1, 2, 3, 5, and 7 between August 1 and leaf drop. Vegetative success for the SCMP during the intermediate monitoring years will be based the survival of a minimum of 320 stems per acre at year 3; a minimum of 260 stems per acre at year 5; and a minimum of 210 stems per acre at year 7. Planted trees in each plot must measure seven feet in height at year 5 and 10 feet in height at year 7, on average. The final vegetative restoration success criteria will be achieving a density of no less than 210 seven- year-old planted stems per acre that must average 10 feet in height in Year 7 of monitoring. 1.4.5 MACROINVERTEBRATES Habitat availability and macroinvertebrate communities will be monitored in streams where functional uplift is attributed to maintenance or improvements in biological communities. Macroinvertebrate sampling will be conducted once a year during monitoring years 3, 5, and 7. Monitoring stations will be located on every perennial restoration and enhancement reach greater than 1,000 feet in length. Additional sampling points will be established per additional 2,000 feet of length on each restoration or enhancem ent reach (1,000’ = 1 point, 3,000’ = 2 points, 5,000’ = 3 points, etc.). Sampling locations will be based on riffle condition and best professional judgment and occur within the same riffle year-to-year. Macroinvertebrate sampling will be processed by a qualified taxonomist and/or NCDWR certified laboratory for macroinvertebrates. Macroinvertebrates will be identified to genus. Biotic indices, including percent EPT (Ephemeroptera, Plecoptera and Trichoptera), North Carolina Biotic Index, Shannon-Weaver Diversity Index, Taxa Richness and a species list for each station, will be listed in the monitoring report. Each report will include a summary of the current results and all past monitoring events in tabular format. The final performance standard will be no net decrease in diversity and abundance by the end of the seventh year of monitoring. 1.4.6 TAR-PAMLICO RIPARIAN BUFFERS Approximately 26.10 acres of Tar-Pamlico riparian buffers (TOB – 200 feet) were restored within the SCMP project area. A Construction and Planting Completion Report was submitted to the NC Department of Environmental Quality (NCDEQ) in accordance with the Division of Water Resources (DWR) Sectio n 401 and Buffer permitting. Vegetation monitoring will occur in monitoring years 1, 2, 3, 5, and 7 between August 1 and Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 9 leaf drop. Within the riparian buffer restoration areas, a minimum of 320 stems per acre must be present at year 3 and a minimum of 260 stems per acre must be present at year 7. Planted trees in each plot must measure an average of seven feet in height at year 5 and 10 feet in height at year 7. Volunteer species may count towards the stems per acre requirements, but species must be included on the approved planting palette. Any single species will only account for up to 50 percent of the required number of stems within any vegetation plot and shall include a minimum of four native hardwood species or four native hardwood tree and native shrub species. Where the vegetation plot is dominated by volunteer species, remedial action as specified in the Adaptive Management Plan may be required. The extent of invasive species coverage will also be monitored and controlled as necessary throughout the required monitoring period. 1.4.7 VISUAL ASSESSMENT Visual assessments of all stream reaches will be conducted annually. Photographs will be used to visually document system performance and any areas of concern related to streambank and bed stability, condition of in-stream structures, channel migration, excess sediment, active headcuts, live stake mortality, invasive plant species or animal browsing, easement boundary encroachments, and general streambed conditions.

Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 12 3 METHODS Stream cross-section monitoring was conducted using a Topcon AT-B4 Automatic Level. Three-dimensional coordinates associated with cross-section data were collected in the field (NAD83 State Plane feet PIPS 3200). Morphological data were collected at 14 cross-sections. Following field activities, survey data was imported into Microsoft Excel®, the OSU STREAM Modules Reference Reach Spreadsheet1, and the NCDMS cross-section ShinyApp tool for processing and analysis. The crest gauges and groundwater monitoring wells include an automatic Onset Hobo pressure transducer set in PVC piping. Visual observations (i.e. wrack or debris lines) will also be used to document out of bank events. Vegetation success is being monitored at a total of 25 permanent vegetation plots—13 within riparian buffer areas and 12 within wetland enhancement areas. Vegetation plot monitoring follows the Carolina Vegetation Survey (CVS) Level 1 (Planted Stem Inventory Plots) and Level 2 (Total Wood Stem Inventory Plots) survey protocols and includes analysis of species composition and density of planted species. In the field, the four comers of each plot were permanently marked with a large T-post at the origin and small T-posts at the other corners. Photos of each plot are taken from the origin corner facing across the plot each monitoring year. Tree species and height are recorded for each planted stem. 1 Mecklenburg, Dan & Ward, Andy. (2011).

Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 13 4 MONITORING YEAR 2 ASSESSMENT AND RESULTS The dates of MY 2 monitoring activities are detailed in Appendix A, Table 2. All MY2 monitoring data is presented in this report and in the appendices. Monitoring Year 2 (MY2) activities occurred from September to November 2023. This report presents the data for MY2. The SCMP meets the MY2 success criteria for stream hydrology, stream pattern, profile, and dimension. The SCMP generally meets the MY2 succe ss criteria for wetland hydrology. However, one well in Wetland 10 does not meet the success criteria for percent hydroperiod and two wells, one in Wetland 10 and one in Wetland 12, do not meet success criteria for consecutive days of saturation. The SCMP generally meets the MY2 success criteria for vegetation. However, five individual vegetation plots did not meet MY2 success criteria for stems per acres, and two individual vegetation plots did not meet success criteria for percent of dominant species. The stream restoration appears to be generally progressing towards success criteria. However, the headwater reach of SA continues to lack many aspects of headwater stream channel formation, and indicators of a defined channel are weak in the majority of the reach for SB. All monitoring device locations are depicted on the Current Condition Plan View (CCPV) (Appendix B, Figure 1). 4.1 STREAM MORPHOLOGICAL ASSESSMENT 4.1.1 STREAM HORIZONTAL PATTERN & LONGITUDINAL PROFILE Visual assessment was utilized for assessment of MY2 horizontal and vertical stability. The visual assessment for each stream reach documented that during MY2, stream channel pattern, longitudinal profiles, and in-stream structure location/function still closely match the profile design parameters and MY0/baseline conditions (Appendix D). Minor channel adjustments in riffle slopes, pool depths and pattern were observed based on natural sediment migration and stream bank vegetation establishment but do not present a stability concern. 4.1.2 STREAM HORIZONTAL DIMENSION The MY2 channel dimensions generally match the design parameters and are within a stable range of tolerance. Twelve cross-sections are located on restoration reaches, with six located in riffles and six located in pools. Of the five riffle cross sections in stream A and one in stream K, all had BHRs <1.2 and Entrenchment Ratios >2.2, meeting performance standards. All twelve permanently installed cross-sections show little to no change in bankfull area when compared to as-built measurements. It is expected that over time some pools may accumulate fine sediment and organic matter, however, this is not an indicator of channel instability. Maximum riffle depths are expected to fluctuate slightly throughout the monitoring period as the channels adjust to the post-restoration flow regime. Please note that previous years’ data was reevaluated at MY2 to ensure accuracy and consistency. As a result of this review, some MY0 and MY1 ER calculations were reevaluated to exclude areas below bankfull elevation located outside of channel. In addition, some MY0 and MY1 bankfull elevation determinations were reassessed and adjusted at MY2 to more accurate and consistent values. More information on adjusted values can be found in Appendix D. Cross-section overlays and measurements can be found in Appendix D and summarized in the tables below.

Stream SA was observed to lack many indicators of headwater stream channel formation. As noted in Table 4.2.1.1, onsite hydrology data indicates the occurrence of multiple bankfull events over the course of MY2, including bankfull levels recorded for approximately four months from 1/21 to 5/24/2023. However, visual observations of the headwater stream reach lack evidence of sediment transport, deposition, and sorting, and OHWM. In addition, the channel is being colonized by various herbaceous species, primarily goldenrod (Solidago altissima). The SB headwater reach exhibited multiple indicators of headwater stream formation including scour, sediment deposition, and matted vegetation ; however, indicators of a defined channel are limited in the majority of the reach. Photos of headwater reaches Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 15 can be found in the Photostations Photolog in Appendix B. NCDEQ Stream Assessment forms for each headwater restoration reach can be found in Appendix D. 4.2 STREAM HYDROLOGY Stream hydrology restoration was monitored via five crest gauges installed along restoration reaches. Stream hydrology performance criteria is the documentation of four separate bankfull flow events in separate monitoring years. Bankfull events were determined by crest gauge water levels recorded above ground surface. Eight bankfull events were recorded within the headwater reach of SA (CG1), and 24 bankfull events were recorded within the headwater reach of SB (CG3). Twenty-two bankfull events were recorded along reach SK (CG2). Five were recorded in conjunction with rainfall events based on onsite rainfall gauge data; the other 17 were not related to a rainfall event. However, based on nearby Wunderground weather station data, it is possible that onsite rain gauge data for Jan- May 2023 is inaccurate. Within SA1, water levels were above bankfull levels for all but 2 days of the monitoring period. Crest gauge 5, along SA2, had a data error with the logger, and data was not recovered. Overall, stream restoration reaches are on track to reach hydrology performance standard targets during the monitoring period. A summary of bankfull events is located in in Table 4.2.1 below. Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 16 4.2.1.1 MY2 BANKFULL EVENTS SUMMARY TABLE 4.3 WETLAND HYDROLOGY Hydrology data were collected from six shallow groundwater monitoring wells within wetland enhancement areas to assess wetland hydrologic performance standards. During MY2, enhancement areas on average were saturated within 12-inches of the soil surface for 101 days (43 percent of the growing season), meeting the MY2 performance standard of 17 days (seven percent of the growing season).

At the completion of MY1, the site was not on track to meet interim vegetative success criteria. Therefore, a supplemental planting was completed in April 2023. MY2 vegetation data can be found in Appendix C with the Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 18 vegetation plot photos located in Appendix B. The MY2 average planted density is 469 stems per acre, which meets the interim measure of vegetative success of at least 320 planted stems per acre at the end of the third monitoring year. However, five individual plots are not currently meeting interim success criteria for stems per acre (VP 3, 5, 14, 23, and 25), and five are at risk of not meeting interim success criteria for stems per acre (VP 7, 8, 12, 13, and 19). In addition, in two plots, the dominant species makes up >50% of the stems present, exceeding success criteria of ≤50% (VP 10 and 11). Volunteer species noted at MY2 consisted of winged elm (Ulmus alata). Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is well established throughout the project. A detailed breakdown of individual plot performance can be found in Appendix C, Table 5a. 4.4.1.1 VEGETATION MY2 PERFORMANCE STANDARDS Performance Standards MY1 MY2 All Vegetation Plots Stems/Acre 320 (MY3) 311 481 260 (MY5) 210 (MY7) Average Stem Height (ft) 7-ft (MY5) 1.62 2.25 10-ft (MY7) Riparian Buffer Plots Only Species Count ≥ 4 4 6 % Cover of Dominant Species ≤ 50 % 50% 38% 4.5 MACROINVERTEBRATES In accordance with the PRMP, no macroinvertebrate sampling occurred in MY2. Swift Creek Permittee Responsible Mitigation Plan WSP Project No. 6250180180 WSP January 2024 Page 19 5 CONCLUSION The second year of monitoring for the Swift Creek PRMP has been completed. Monitoring results indicate that the SCMP is on track to meet stream hydrology, stream pattern, profile, and dimension performance standards by Monitoring Year 7. Monitoring Year 2 (MY2) activities occurred from September to November 2023. This report presents the data for MY2. The SCMP meets the MY2 success criteria for stream hydrology, stream pattern, profile, and dimension. The SCMP generally meets the MY2 success criteria for wetland hydrology. However, one well in Wetland 10 does not meet the success criteria for percent hydroperiod and two wells, one in Wetland 10 and one in Wetland 12, do not meet success criteria for consecutive days of saturation. The SCMP generally meets the MY2 success criteria for vegetation. However, five individual vegetation plots did not meet MY2 success criteria for stems per acres (VP 3, 5, 14, 23, and 25), and two individual vegetation plots did not meet success criteria for percent of dominant species (VP 10 and 11). The stream restoration appears to be generally progressing towards success criteria. However, the headwater reach of SA continues to lack many aspects of headwater stream channel formation, and indicators of a defined channel are limited in the majority of the reach for SB. Based on these results, the SCMP generally is on trajectory to meet interim and final success criteria. However, adaptive management, including additional planting and monitoring, may have to be considered in areas of concern. Macroinvertebrate sampling was not scheduled to occur during MY2, per the mitigation plan. APPENDIX A BACKGROUND TABLES Table 1.
