We have revised the Year 4 Monitoring Report document in response to this review. Comment: Cover Sheet: Please add the RFP# to the cover sheet. Response: RFP: 16-005568 has been added to the cover sheet as requested. Comment: Section 1.0 Executive Summary: Please identf the thermal regime (warm) in the project summary information. Response: Warm-temperature thermal regime has been added to the executive summary. Comment: Section 1.0 Executive Summary: The report indicates well BSAW8 was installed during MY4 in an adjacent wetland. Please include the location of this well on a figure and provide an interpretation of the data relative to the site. Response: BSAW8 (MW8) has been added to the CCPV along with a written description located in the executive summary. Comment: Section 2.1.4 Visual Assessment:Add discussion for the Reach 2 grade control structure identified in Table 5 as not functioning. Evaluate any concern associated with the reduced function of the structure and potential impact on the system. Response: Reach 2 grade control failed during MY3 but repaired in MY4. Table 5 has been updated to show no structures failing. Comment:Appendix A - CCPV: Indicate the location of the Reach 2 structure of concern on the CCPV. Response: See above response to comment. Page 1 Michael Baker We Make a Difference INTERNATIONAL Comment:Appendix A - Table 1:Please take credit calculations out to 3 digits (5,301.867 SMU). Response: Table 1 credit calculations have been revised to show 3 digits. Digital files: Comment: DMS commented last year about mismatches between spatial feature lengths and values reported in the asset table. The submitted features resolved the discrepancies for RJ-R5. DMS understands that credits for R6 and T4 were calculated using valley length, and as such, these features will not match the asset table. However, T3's feature length is 87 ft compared to the reported length of 70 ft. DMS wants to verify that there are no available features that accurately characterize the reported length for T3. Response: The as-built survey length for reach T3 is 87.96 ft which matches the spatial feature length value for T3. However, in Table 1 we are requesting 70 SMU at 1:1 credit to reflect the credits reported in the Mitigation plan. Comment: Please spatially identify the area experiencing the grade control issue (Table 5) in the CCPV, and include this feature in the digital submission. Response: See response to comment 4. Comment: Please submit photos as JPEGs. Response: JPEGs have been added in the e-submission support files. Comment: Please provide the data used to create the streamflow and groundwater well figures. Response: Streamflow and groundwater well raw spreadsheets have been included in the support files. Two hard copies and one pdf copy along with updated digital files uploaded to a thumb drive are being provided.

BROWNS SUMMIT CREEK RESTORATION PROJECT,DMS PROJECT NO.96313 DECEMBER 2020,MONITORING YEAR 4 OF 7 1. EXECUTIVE SUMMARY Michael Baker Engineering,Inc.(Michael Baker)restored approximately 3,903 linear feet(LF)of jurisdictional stream and enhanced 2,478 LF of stream (of which 559 is for BMPs) along unnamed tributaries (UT) to the Haw River and restored over 4.44 acres of wetland (existing channel lengths). The unnamed tributary (mainstem) has been referred to as Browns Summit Creek for this project. All of these stream features are in the warm-temperature thermal regime. In addition, Baker constructed two best management practices (BMPs) within the conservation easement boundary. The Browns Summit Creek Restoration Project(project)is located in Guilford County,North Carolina(NC)(Figure 1)approximately three miles northwest of the Community of Browns Summit. The project is located in the NC Division of Water Resources (NCDWR) subbasin 03-06-01 and the NC Division of Mitigation Services (NCDMS) Targeted Local Watershed (TLW) 03030002-010020 (the Haw River Headwaters) of the Cape Fear River Basin. The purpose of the project is to restore and/or enhance the degraded stream, wetland, and riparian buffer functions within the site. A recorded conservation easement consisting of 20.2 acres (Figure 2) will protect all stream reaches, wetlands, and riparian buffers in perpetuity. Examination of the available hydrology and soil data indicate the project will potentially provide numerous water quality and ecological benefits within the Haw River watershed,and the Cape Fear River Basin. Based on the NCDMS 2009 Cape Fear River Basin Restoration Priority (RBRP) Plan, the Browns Summit Creek Restoration Project area is located in an existing targeted local watershed(TLW) within the Cape Fear River Basin (2009 Cape Fear RBRP), but is not located in a Local Watershed Planning (LWP) area. The restoration strategy for the Cape Fear River Basin targets specific projects, which focuses on developing creative strategies for improving water quality flowing to the Haw River in order to reduce non-point source (NPS)pollution to Jordan Lake. The primary goals of the project, set in the Mitigation Plan, are to improve ecologic functions and to manage nonpoint source loading to the riparian system as described in the NCDMS 2009 Cape Fear RBRP. These goals are identified below: • Create geomorphically stable conditions along the unnamed tributaries across the site, • Implement agricultural BMPs to reduce nonpoint source inputs to receiving waters, • Address known and obvious water quality and habitat stressors present on site, • Restore stream and floodplain connectivity, and • Restore and protect riparian buffer functions and corridor habitat. To accomplish these goals,the following objectives were identified: • Restore existing incised,eroding,and channelized streams by creating stable dimension and connecting them to their relic floodplains; • Re-establish and rehabilitate site wetlands that have been impacted by cattle, spoil pile disposal, channelization, subsequent channel incision, and wetland vegetation loss; • Prevent cattle from accessing the conservation easement boundary by installing permanent fencing and thus reduce excessive stream bank erosion and undesired nutrient inputs; • Increase aquatic habitat value by improving bedform diversity, riffle substrate and in-stream cover; creating natural scour pools; adding woody debris and reducing sediment loading from accelerated stream bank erosion; MICHAEL BAKER ENGINEERING,INC. 1 BROWNS SUMMIT CREEK RESTORATION PROJECT,DMS PROJECT NO.96313 DECEMBER 2020,MONITORING YEAR 4 OF 7 • Construct a wetland BMP on the upstream extent of Reach R6 to capture and retain and for sediment to settle out of the water column; • Construct a step pool BMP channel to capture and disperse volumes and velocities by allowing discharge from a low density residential development to spread across the floodplain of Reach R4; thereby,diffusing energies and promoting nutrient uptake within the riparian buffer; • Plant native species within the riparian corridor to increase runoff filtering capacity, improve stream bank stability and riparian habitat connectivity, and shade the stream to decrease water temperature; • Control invasive species vegetation within the project area and,if necessary,continue treatments during the monitoring period; and • Establish a conservation easement to protect the project area in perpetuity. In accordance with the Mitigation Plan and the project-applicable DMS guidance document "Monitoring Requirements and Performance Standards for Stream and/or Wetland Mitigation. Version 1.5, Dated June 8, 2012, no formal vegetation plot monitoring was performed, nor were any stream cross-sectional surveys conducted as part of the Year 4 monitoring effort.A visual assessment of the site is emphasized this year,with the full vegetation and cross-section survey work to resume for the Year 5 monitoring in 2021. No Stream Problem Area(SPA) or Vegetation Problem Area(VPA)were discovered during Year 4 monitoring. SPA 3-1 reported during Monitoring Year 3 (MY3) was repaired and remained stable throughout the MY4. VPA 3-1 reported in MY3 was treated in April 2020 and July 2020 along with any other invasive species found on the site. Baker plans on retreating these areas for future monitoring years. VPA 3-2 and 3-3 reported in MY3 were supplemental planted with species appropriate for the area planted and approved by the mitigation planting list. These areas were also seeded to help establish vegetation and help prevent scouring. Year 4 flow monitoring demonstrated that all flow gauges (BSFL1,BSFL2 and BSFL3)met the stated success criteria of 30 days or more of consecutive flow through R4, T3 and T1 respectively. Flow gauge BSFL1 documented 137 days of consecutive flow in R4,while flow gauge BSFL2 documented 202 days of consecutive flow in T3, and BSFL3 documented 310 days of consecutive flow in Ti. The gauges demonstrated similar patterns relative to rainfall events observed in the vicinity of the Site as shown in the flow gauge graphs in Appendix E. During Year 4 monitoring,the R1 crest gauge documented two post-construction bankfull event from February 2020 at 0.91 feet and second event in November of 2020 at 1.49 feet. The site had already meet the bankfull flow requirement of two bankfull events within two separate monitoring years in previous monitoring years (MY1 and MY2). Eight wells were installed in the wetland restoration areas. One additional well, BSAW8 was installed during MY4 to gather additional data in adjacent wetlands. BSAW8 is located adjacent to wetland type 5 (Hydrologic reestablishment) where BSAW1 is located. BSAW8 data shows the wetland preforming well above success criteria. Seven of the eight are preforming successfully. One well did not meet success (BSAW2). However, BSAW2 shows hydrology coming to within twelve inches of the ground surface relatively consistently and having more cumulative days meeting criteria than previous years.It is anticipated that wetland hydrology will improve with additional monitoring. MICHAEL BAKER ENGINEERING,INC. 2 BROWNS SUMMIT CREEK RESTORATION PROJECT,DMS PROJECT NO.96313 DECEMBER 2020,MONITORING YEAR 4 OF 7 Summary information/data related to the Site 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 and in the Mitigation Plan available on the DMS website. Any raw data supporting the tables and figures in the Appendices is available from DMS upon request. This report documents the successful completion of the Year 4 monitoring activities for the post-construction monitoring period. 2. METHODOLOGY The seven-year monitoring plan for the Site includes criteria to evaluate the success of the stream and vegetation components of the Site. The methodology and report template used to evaluate these components adheres to the DMS monitoring report template document Version 1.5 (June 8,2012),which will continue to serve as the template for subsequent monitoring years. The vegetation-monitoring quadrants follow CVS-DMS monitoring levels 1 and 2 in accordance with CVS-DMS Protocol for Recording Vegetation,Version 4.1 (2007). Stream survey data was collected to a minimum of Class C Vertical and Class A Horizontal Accuracy using Leica TS06 Total Station and was georeferenced to the NAD83 State Plane Coordinate System, FIPS3200 in US Survey Feet,which was derived from the As-built Survey. The specific locations of monitoring features, such as vegetation plots, permanent cross-sections, reference photograph stations, crest gauges and flow gauges, are shown on the CCPV map found in Appendix B. Channel construction began in October 10,2016 at the upstream extent of the site and worked in the downstream direction (begin on Reach 6 and ended with Reach 1). The construction was completed on March 8, 2017. Planting was installed as major reaches were completed and finalized by March 10,2017. Minor supplemental planting occurred in March of 2018. The Monitoring Year 4 visual site assessment was collected in November 2020.Visual Assessment is contained in Appendix B. 2.1 Stream Assessment Historically, the Browns Summit site has been utilized for agriculture. Cattle have had direct access to the entire site. Ponds were located throughout the project, including within the alignment of R1, R3, R4, and R6. Channelization was clearly confirmed by the historical aerial photo from 1937 and spoil piles were found along several of the reaches. The Project involved the restoration and enhancement of the headwater system. Restoration practices involved raising the existing streambed and reconnecting the stream to the relic floodplain to restore natural flow regimes to the system. The existing channels abandoned within the restoration areas were filled to decrease surface and subsurface drainage and to raise the local water table. Permanent cattle exclusion fencing was provided around all proposed reaches and riparian buffers, except along reaches where no cattle are located. 2.1.1 Morphological Parameters and Channel Stability Cross-sections were classified using the Rosgen Stream Classification System,and all monitored cross- sections fall within the quantitative parameters defined for channels of the design stream type. Morphological survey data are presented in Appendix D. MICHAEL BAKER ENGINEERING,INC. 3 BROWNS SUMMIT CREEK RESTORATION PROJECT,DMS PROJECT NO.96313 DECEMBER 2020,MONITORING YEAR 4 OF 7 A longitudinal profile was surveyed for the entire length of channel immediately after construction to document as-built baseline conditions for the Monitoring Year 0 only. Annual longitudinal profiles were not planned to be conducted during subsequent monitoring years unless channel instability has been documented or remedial actions/repairs are required by the U.S. Army Corps of Engineers (USACE)or DMS. However, during preparation of the MY1 monitoring report, it was discovered that the data provided by the construction contractor's survey subcontractor for as-built was of low quality and insufficient. The quality of the sealed as-built survey provided by the contractor wasn't discovered until the MY1 survey was overlain on top of the MY0 cross sections. The channel in reality had not fluctuated nearly as dramatically as shown in Figure 5 (cross section overlays)and has remained stable and is performing as designed. This has been documented through field inspections throughout subsequent monitoring years by Michael Baker and DMS staff. Due to the MY0 survey quality discovered during MY1, Michael Baker proposed to utilize the detailed survey data and associated parameters collected during MY1 by a different surveyor as the basis of comparison through the monitoring phase of the project. This will ensure an accurate assessment of success and trends throughout the life of the project. The contractor had the site's longitudinal profile re-surveyed incase future comparisons are required. The longitudinal profile overlay was provided in previous reports. Additionally,per DMS request, bankfull ratio is calculated by adjusting the bankfull line vertically to recreate the as-built cross-sectional area. Once the cross-sectional area is the same bankfull ratio is calculated and recorded. After bankfull ratio is recorded then previous bankfull elevation is set and the remaining data is calculated. However, in this case, due to a poor as-built survey we are referencing all calculations to the Monitoring Year 1 survey. This will help ensure that the cross-sections best represent the actual characteristics of the stream. 2.1.2 Hydrology To monitor on-site bankfull events,one crest gauge(crest gauge#1)was installed along R1's left bank at bankfull elevation. The crest gauge readings are presented in Appendix E. Thus, the site has meet the bankfull flow requirements of two bankfull events within two separate years. Year 4 flow monitoring demonstrated that all flow gauges(BSFL1,BSFL2 and BSFL3)met the stated success criteria of 30 days or more of consecutive flow through R4,T3 and T 1 respectively. The gauges demonstrated similar patterns relative to rainfall events observed in the vicinity of the Site as shown in the flow gauge graphs in Appendix E. 2.1.3 Photographic Documentation Visual inspection of the site are conducted at a minimum of twice a year. Representative photographs for Monitoring Year 4 were taken along each Reach in March 2020 and are provided in Appendix B. 2.1.4 Visual Stream Morphological Stability Assessment The visual stream morphological stability assessment involves the qualitative evaluation of lateral and vertical channel stability, and the integrity and overall performance of in-stream structures throughout the Project reaches as a whole. Habitat parameters and pool depth maintenance are also measured and scored. During Year 4 monitoring,Michael Baker staff walked the entire length of each of the Project reaches several times throughout the year, noting geomorphic conditions of the stream bed profile (riffle/pool facets), both stream banks, and engineered in-stream structures. Representative photographs were taken per the Site's Mitigation Plan,and the locations of any SPAs were documented in the field for subsequent mapping on the CCPV figures. A more detailed summary of the results for the visual stream stability assessment can be found in Appendix B,which includes supporting data tables, as well as general stream photos. MICHAEL BAKER ENGINEERING,INC. 4 BROWNS SUMMIT CREEK RESTORATION PROJECT,DMS PROJECT NO.96313 DECEMBER 2020,MONITORING YEAR 4 OF 7 3.1 Vegetation Assessment In order to determine if the success criteria were achieved,vegetation-monitoring quadrants were installed and are monitored across the site in accordance with the CVS-DMS Protocol for Recording Vegetation,Version 4.1 (2007). The vegetation monitoring plots are a minimum of 2 percent of the planted portion of the Site with fourteen plots established randomly within the planted riparian buffer areas per Monitoring Levels 1 and 2. The sizes of individual quadrants are 100 square meters for woody tree species. 4.1 Wetland Assessment Eight(8) groundwater monitoring wells were installed in the wetland mitigation area to document hydrologic conditions of the restored wetland area. The wetland gauges are depicted on the CCPV figures(Figure 2)found in Appendix B. Installation and monitoring of the groundwater stations have been conducted in accordance with the USACE standard methods. 3.

This number is calculated as the easement acreage minus any existing mature tree stands that were not subject to supplemental planting of the understory, the channel acreage, crossings or any other elements not directly planted as part of the project effort. 2 =The acreage within the easement boundaries. 3= Encroachment may occur within or outside of planted areas and will therefore be calculated against the overall easement acreage. In the event a polygon is cataloged into items 1,2 or 3 in the table and is the result of encroachment,the associated acreage should be tallied in the relevant item(i.e.,item 1,2 or 3)as well as a parallel tally in item 5. 4=Invasives may occur in or out of planted areas,but still within the easement and will therefore be calculated against the overall easement acreage. Invasives of concern/interest are listed below. The list of high concern spcies are those with the potential to directly outcompete native, young, woody stems in the short-term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established tree/shrub stands over timeframes that are slightly longer(e.g. 1-2 decades). The low/moderate concern group are those species that generally do not have this capacity over the timeframes discussed and therefore are not expected to be mapped with regularity, but can be mapped, if in the judgement of the observer their coverage, density or distribution is suppressing the viability,density, or growth of planted woody stems. Decisions as to whether remediation will be needed are based on the integration of risk factors by EEP such as species present, their coverage, distribution relative to native biomass, and the practicality of treatment. For example, even modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control,but potentially large coverages of Microstegium in the herb layer will not likley trigger control because of the limited capacities to impact tree/shrub layers within the timeframes discussed and the potential impacts of treating extensive amounts of ground cover. Those species with the "watch list" designator in gray shade are of interest as well, but have yet to be observed across the state with any frequency. Those in red italics are of particular interest given their MICHAEL BAKER ENGINEERING, INC. BROWNS SUMMIT CREEK RESTORATION PROJECT(DMS PROJECT NO.
