Vegetation - general Invasive vegetation (mostly privet) is still significant (3.12 acres, 15% of easement). Please indicate how and when this will be addressed over the next year. RES will treat the invasive vegetation by cutting and spraying it. Due to the steep slopes in the easement, mulching is not an option. RES plans for the treatments to take place once in the spring, summer, and fall of 2019. This detail has been added to the report. Hydrology - general While DMS acknowledges RES' plans and efforts to validate withheld credits on the site via adaptive management (stream characterization, flow gauges and excavation as described in the Adaptive Management section), please understand that DMS cannot approve any invoicing for the project beyond the current credit -approved amounts until the IRT approves any adaptive plans and subsequently approves credits on these credit -withheld reaches. Thompson Creek 1-2 creditable footage should be 1014, not 1029 (approved mitigation plan length of 1314 minus 300). Please verify and change if agreed or clarify. This is correct and has been updated in Table 1. Project Credits / Table 1 During the 7/25/2018 field meeting with the IRT, additional hydrology monitoring was discussed along reaches where poor hydrology was observed in stream sections near the former ponds where silting had resulted in the lack of a well-defined channel, or a channel form that was dry. The following credits (716.7 total) are currently being withheld due to hydrology / channel formation questions: Thompson 1 (100+00-102+50) 250 feet of Enhancement 1 (166.7 SMUs). Thompson 1 (102+50-105+50) 300 feet of Restoration (300 SMUs). Dale 1 (200+00-201+22) 122 feet Enhancement 1 (81.3 SMUs). Dale 1 (201+22-203+75) 253 feet of Enhancement 1 (168.7 SMUs). res. us 0 Please explain in the Table 1 notes the LF adjustments and any adaptive management plans. Done.

Goals and Objectives The project goals address stressors identified in the TLW and include the following: • Improve water quality within the restored channel reaches and downstream watercourses by reducing sediment and nutrient inputs and increasing dissolved oxygen levels • Improve local aquatic and terrestrial ecological function via stream shading, habitat complexities, and organic/woody material introduction • Improve aquatic and benthic macroinvertebrate habitat and associated stream bed form • Improve site hydrology and attenuate flood flows on-site and downstream • Provide approximately 18.6 acres of riparian area restoration with a native plant community • Protect stream and riparian improvements with livestock best management practices • Protect the site in perpetuity with a permanent conservation easement The project goals will be addressed through the following project objectives: • Implement Priority I or II restoration of 5,992 feet of stream and enhancement of 625 feet of stream • Implement appropriate changes in dimension, pattern and/or profile to create geomorphologically stable conditions along project area reaches • Modify degraded stream channels to enable proper sediment transport capacity and improved stream bed character • Construct a floodplain bench that is accessible at the proposed bankfull channel elevation. • Remove a major impoundment • Integrate in -stream structures and native bank vegetation • Plant native woody and herbaceous riparian vegetation with a minimum width of 50 feet from the edge of the restored channels • Eradicate invasive, exotic or undesirable plant species • Install cattle exclusion fencing, two new wells, two new cattle drinking stations, and upgrade eight existing cattle drinking stations 1.2. Success Criteria The success criteria for the Pee Dee Stream Restoration Site follows accepted and approved success criteria presented in the USACE Stream Mitigation Guidelines and subsequent NCDMS and agency guidance. Specific success criteria components are presented below. 1.2.1. Stream Restoration Dimension — Cross-section measurements should indicate little change from the as -built cross- sections. If changes do occur, they will be evaluated to determine whether the adjustments are associated with increased stability or whether they indicate movement towards an unstable condition. Pattern and Profile — Measurements and calculated values should indicate stability with little deviation from as -built conditions and established morphological ranges for the restored stream type. Pool depths may vary from year to year, but the majority should maintain depths sufficient to be observed as distinct features in the profile. The pools should maintain their depth with flatter Pee Dee Stream Restoration Project 5 RES NCDMS Project No. 95350 Annual Monitoring Report Monitoring Year 4 of 7 January 2019 water surface slopes, while the riffles should remain shallower and steeper. Pattern measurements will not be collected unless conditions seem to indicate that a detectable change appears to have occurred based on profile and/or dimension measurements. Substrate — Calculated D5o and D84 values should indicate coarser size class distributions of bed materials in riffles and finer size class distributions in pools. The majority of riffle pebble counts should indicate maintenance or coarsening of substrate distributions. Generally, it is anticipated that the bed material will coarsen over time. Sediment Transport — Depositional features should be consistent with a stable stream that is effectively managing its sediment load. Point bar and inner berm features, if present, should develop without excessive encroachment of the channel. Isolated development of robust (i.e. comprised of coarse material and/or vegetation actively diverting flow) mid -channel or lateral bars will be acceptable. Likewise, development of a higher number of mid -channel or lateral bars that are minor in terms of their permanency such that profile measurements do not indicate systemic aggradation will be acceptable, but trends in the development of robust mid -channel or alternating bar features will be considered a destabilizing condition and may require intervention or have success implications. 1.2.2. Surface Water Hydrology Monitoring of stream surface water stages should indicate recurrence of bankfull flows on average every 1 to 2 years. At a minimum, throughout the monitoring period, the surface water stage should achieve bankfull or greater elevations at least twice. The bankfull events must occur during separate monitoring years. 1.2.3. Vegetation Riparian vegetation monitoring shall be conducted for a minimum of seven years to ensure that success criteria are met per USACE guidelines. Accordingly, success criteria will consist of a minimum survival of 320 stems per acre by the end of the Year 3 monitoring period, a minimum of 260 stems per acre at the end of Year 5, and a minimum of 210 stems per acre in Year 7. If monitoring indicates either that the specified survival rate is not being met or the development of detrimental conditions (i.e., invasive species, diseased vegetation), appropriate corrective actions will be developed and implemented. 1.3. Project Setting and Background The Pee Dee Stream Restoration Site (Site) encompasses approximately 21.0 acres of predominately agricultural land and includes three tributaries to Clarks Creek — Thompson Creek, Dale Branch, and Jerry Branch. The Site is located in the Yadkin River Watershed (NCDWR sub -basin 03-07-10 and HUC 03040104020020) approximately 1 mile south of the town of Pee Dee, NC in Montgomery County (Figure 1). Clarks Creek is listed as Class C water (NCDWR) and flows into the Pee Dee River. The Site is located within a NCDMS targeted local watershed. Following 2016 monitoring the NCIRT requested a review of the differential between the Approved Mitigation Plan and Baseline Monitoring Report. The table below details the discrepancies by reach. The primary cause of increased baseline SMUs is survey methodology (thalweg vs. centerline). The Mitigation Plan lengths were based on centerline. Other causes of increased SMUs include field adjustments during construction and the design assumption of the channel pattern after pond removal. Additionally, credits for the stream reaches associated with the pond removals will be held until a later date. This is discussed further in Section 1.4.4. The new SMU total for this site is 5,691.6 (Table 1). Pee Dee Stream Restoration Project 6 RES NCDMS Project No. 95350 Annual Monitoring Report Monitoring Year 4 of 7 January 2019 1.4. Project Performance Monitoring Year 4 (MY4) data was collected in November 2018. Monitoring activities included visual assessment of all reaches and the surrounding easement, 16 permanent photo stations, 12 pebble counts, and 6 bank pin arrays. Per the Approved Mitigation Plan, vegetation plot and cross-section data were not collected in MY4. Summary information/data related to the occurrence of items such as beaver or easement encroachment 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 Mitigation Plan (formerly Restoration Plan) documents available on the NCDMS website (http://portal.ncdenr.org/web/eep). All raw data supporting the tables and figures in the appendices is available from NCDMS upon request. 1.4.1. Vegetation Visual assessment of the easement (Appendix B - Table 6, Figure 2) indicates that herbaceous vegetation is well established throughout the project. Invasive exotic vegetation has been identified throughout the Site as Chinese privet (Lingustrum sinense). Invasive species treatments were administered in February and June of MY4. Treatments will continue throughout the monitoring period. RES plans to cut and spray the privet again in the spring, summer, and fall of 2019. RES remapped the invasive areas in MY4 and approximate size and locations of the invasive species areas are in Table 6 and on Figure 2. Vegetation plot data was not collected in MY4. It will be collected and reported again in MY5 and MY7. 1.4.2. Stream Geomorphology Visual assessment of the stream was performed to document signs of channel instability, such as eroding banks, structural instability, or excessive sedimentation.

With exception to the areas noted in Section Pee Dee Stream Restoration Project 7 RES NCDMS Project No. 95350 Annual Monitoring Report Monitoring Year 4 of 7 January 2019 1.4.4, there was no indication of instability was observed during the visual assessment (Table 5 and Figure 2). Structures are intact and performing as designed. Geomorphic data for MY4 was not collected. It will be collected and reported again in MY5 and MY7. Substrate monitoring was performed during MY4. Riffle D5o ranged from medium gravel to coarse gravel on Jerry Branch, medium gravel to coarse gravel on Dale Branch, and coarse gravel on Thompson Branch. Substrate will be monitored in future years for shifts in particle size composition. Substrate composition data is presented in Appendix D. 1.4.3. Stream Hydrology Since project completion in April 2015 at least six bankfull events have been documented on both Jerry and Thompson Branch and at least seven on Dale Branch. At least five bankfull events were recorded in MY4. One each on Jerry and Thompson Branches in the form of wrack lines and three on Dale Branch on the crest gauge (Table 13). The project has received multiple heavy precipitation events with no degradation to the channel or structures. 1.4.4. Adaptive Management During a site visit with NCIRT and NCDMS at the Pee Dee Site in July 2018 (Appendix F), several problem areas were identified regarding the drained pond on Thompson 1 and the drained pond/wetland on Dale 1. Per the request of NCIRT, RES developed an Adaptive Mangement Plan to be sent to the IRT in early 2019. The Adaptive Mangement Plan proposes the installation of flow gauges above the old pond on Thompson 1, above the old pond/wetland on Dale 1, and at Cross Section 9 on Dale 2 to document at least intermittent flow. Additionally, RES propses to excavate a baseflow channel through the old pond/wetland on Dale 1. 2.0 METHODS Visual assessments of the project were performed at the beginning and end of the monitoring year. Permanent photo station photos were collected during vegetation monitoring. Additional vegetation or stream problem areas within the project area were photo -documented. Geomorphic measurements were taken using a Topcon GTS -312 Total Station. Three-dimensional coordinates associated with cross- section and profile data were collected in the field and geo-referenced (NAD83 State Plane feet FIPS 3200). Morphological data was limited to 22 cross-sections. Survey data (MYO, MY I, MY2, MY3, MY5, MY7) was imported into CAD, ArcGIS, and Excel for data processing and analysis. Channel substrate was characterized using a Wolman Pebble Count as outlined in Harrelson et al. (1994) and processed using Microsoft Excel. Vegetation success (MYO, MY I, MY2, MY3, MY5, MY7) is being monitored using 14 permanent monitoring plots. Vegetation monitoring followed CVS-EEP Level 1 Protocol for MY and is following Level 2 Protocol Version 4.2 for monitoring years 2-7 (Lee et al. 2008). Level 2 Protocol includes analysis of species composition and density of planted species. Data is processed using the CVS data entry tool. In the field, the four corners of each plot were permanently marked with rebar and photos of each plot taken from the origin each monitoring year. Precipitation data was reported from the NCCRONOS station Uwharrie (Troy) up until its failure in June 2017. Precipitation data is now reported from the NCCRONOS station Albemarle 5.1 SSE. Three crest gauges were installed to document bankfull events, one each on Jerry, Dale, and Thompson branches. Pee Dee Stream Restoration Project 8 RES NCDMS Project No. 95350 Annual Monitoring Report Monitoring Year 4 of 7 January 2019 During quarterly visits to the site, the height of the corkline was recorded and cross-referenced with known bankfull elevations at each crest gauge. 3.0 REFERENCES Harrelson, Cheryl, C.

The main topic of discussion was the IRT's concern over the formation of the streams in and above the old ponds on Thompson 1 and Dale 1. Additionally, invasive species were seen throughout the easement. RES will need to continue to heavily treat the invasive species for the rest of the monitoring period. Specific comments and concerns are below. • Thompson 1 (100+00-102+50): The IRT noted that this reach had a defined flow path but the lack of sorting in the bed material and uniform bedform were characteristic of a stream with less than intermittent flow. It was determined that in order to receive credit on this reach, RES would need to address the issues in the pond bottom below it. 250 feet of Enhancement I credit will be withheld (166.7 SMUs). • Thompson 1 (102+50-105+50): The stream channel in the pond bottom could not be found. As it has been noted on previous site visits, the cracked soil from the pond bottom drying causes any surface water to quickly drain. It is obvious where the channel picks back up near the old dam location. In order to receive credit on any of Thompson 1, RES will need to submit a Remedial Action Plan to address the channel forming and stream flow issues. 300 feet of Restoration credit will continue to be withheld (300 SMUs). • Dale 1 (200+00-201+22): The reach above the pond bottom/wetland had better bedform formation and sorting than the reach above the pond on Thompson. The IRT determined that in order to receive credit on this reach, RES would need to install a flow gauge/camera to document intermittent flow. Credits, however, will be withheld: 122 feet Enhancement I (81.3 SMUs). • Dale 1 (201+22-203+75): This area consists of a wetland that formed in an old pond bottom prior to construction. The stream channel is absent of targeted bedform and riffle/pool sequence in this section. The IRT determined that to receive credits on this reach, RES would need to develop a Remedial Action Plan to address the channel formation and flow issues. 253 feet of Enhancement I credit will be withheld (168.7 SMUs). • Dale 2: The IRT suggested that it would be a good idea to install a flow gauge/camera on this reach preferably between XS 8 and 9 in order to help demonstrate at closeout that the reach was obtaining at least intermittent flows. • Hudson: DMS brought the IRT to this reach to see if they thought it needed a flow gauge. The IRT decided that the reach was short enough that it did not need a flow gauge. In total the amount of credits that are withheld from Pee Dee are 716.7 SMUs. RES will decide if a Remedial Action Plan is appropriate to address the problems in and above the old pond bottoms as well as add a flow camera above the pond bottom on Dale 1 and in-between XS 8 and 9 on Dale 2.
