DMS offers the following comments for the report: Stream Report 1. Section 1.5.2 (1st paragraph) seems to have mixed up the flow gauge location and stage recorder location in the discussion. The stage recorder is identified as being on JH1-A and flow gauge on JH1-B when it should be the opposite. Please correct. 2. Please remove Section 1.5.4 from the stream report since it exclusively deals with the buffer -only section of the project. 3. Recommend removing Figure 2b from the stream report. 4. In Appendix A, please remove any photos from the buffer -only easement from the stream report. 5. On Flow Gauge JH1-A hydrograph, recommend adding number of days of flow after the date range, i.e., 2/16/2022 - 4/4/2022 (47 days). Buffer Report 6. Please update Section 1.3 with the correct riparian buffer restoration credits as reported in the MYO report. The restoration credits should be 642,070.977 and total credits should be 650,162.286. 7. Please remove Section 1.5. We would only expect a discussion of as -built condition in the MYO Baseline report. 8. Replace/update Table 1 in Appendix A so the correct credits are displayed. 9.

Stream Report Comments: 1. Section 1.5.2 (1st paragraph) seems to have mixed up the flow gauge location and stage recorder location in the discussion. The stage recorder is identified as being on JH1-A and flow gauge on JH1-B when it should be the opposite. Please correct. This has been revised accordingly. 2. Please remove Section 1.5.4 from the stream report since it exclusively deals with the buffer - only section of the project. The section has been removed. 3. Recommend removing Figure 2b from the stream report. Figure 2b was included in the report in order to satisfy a previous DMS Digital File Comment from the MYO report (See excerpt below from the MYO Comment Response Memo): ital File Comments: 1. It is not possible to ensure the easement is accurate when compared to the CCPV in the stream asset baseline report, the CCPV does include the entire easement. The digital easement submitted does represent the DMS recorded easement. A requirement of the CCPV is to include the easement boundary, please revise the CCPV in the Stream Baseline Report to include the entire easement boundary. It is complete in the Buffer Baseline Report. Figure 2 has been divided into Figure 2a and 2b so that monitoring devices are legible on 2a and the entire conservation easement is visible on 2b. Therefore, at this time, RES prefers to include the figure per the previous comment; however, if DMS concludes that the previous comment is erroneous, then RES can remove it in future years' monitoring reports. res.us 4. In Appendix A, please remove any photos from the buffer -only easement from the stream report. The photo pertaining to the buffer -only portion of the easement has been removed from Appendix A. 5. On Flow Gauge JH1-A hydrograph, recommend adding number of days of flow after the date range, i.e., 2/16/2022 - 4/4/2022 (47 days). Number of days have been added to the hydrograph accordingly. Buffer Report Comments: 6. Please update Section 1.3 with the correct riparian buffer restoration credits as reported in the MYO report. The restoration credits should be 642,070.977 and total credits should be 650,162.286. RES apologizes for the mistake. A previous version of Table 1 was accidentally copied -and -pasted into this report. The final report has been revised to include the accurate credits and correct version of Table 1 (also refer to comment #8 below). 7. Please remove Section 1.5. We would only expect a discussion of as -built condition in the MYO Baseline report. The Section has been deleted. Note that previous Section 1.6 is now Section 1.5. 8. Replace/update Table 1 in Appendix A so the correct credits are displayed As mentioned in the above response to comment #6 above, the correct table has been included in Appendix A of the final report. 9.

Project Timeline and Contact Information I Proiect Summary 1.1 Project Location and Description The Strawberry Hill Mitigation Project ("Project") is located within a mostly rural watershed in Johnston County near Smithfield, NC at the crossroads of Yelverton Grove Road and Brogden Road. The Project lies within the Neuse River Basin, North Carolina United States Geological Survey (USGS) 8-digit Cataloguing Unit 03020201 (Meuse 01) and 14-digit hydrologic unit code (HUC) 03020201140010, a NC Division of Mitigation Services (DMS) Targeted Local Watershed (TLW) and the Division of Water Resources (NCDWR) sub -basin 03-04-02 (Figure 1). The Project restores 3,719 linear feet (LF) that will provide water quality benefit for 383 acres of drainage area. Additionally, the Project restores and preserves riparian buffer area within the project area, which provides riparian buffer credits for the Neuse 01 watershed. Conditions pertaining to the buffer mitigation component of this Project will be provided in separate monitoring reports each year. Also, notably, the Project is in very close proximity (approximately 0.4 miles) to the RES Polecat Stream Mitigation Bank Site, offering even more functional uplift to the local watershed. The Project area, in whole, is comprised of a 22.12-acre easement involving two unnamed tributaries to Polecat Branch, which eventually drains to the Neuse River. One of the tributary streams, and its associated ditches, are not subject to stream mitigation and are only utilized for buffer mitigation. That portion of the Project will not be discussed in this stream mitigation monitoring report but will be included in a separate monitoring report. Therefore, the stream mitigation component of the Project involves one tributary, whose total length prior to restoration was 3,267 LF. The Project is accessible from both Yelverton Grove Road and Brogden Road. Coordinates for the Project area are approximately 35.469579,-78.323896 at the NC Department of Transportation (DOT) culvert exiting the Project at Brogden Road. 1.2 Project Components Prior to restoration, the project stream was significantly impacted by historic relocation and straightening, crop production, timbering, and lack of riparian buffer. Proposed improvements to the Project will help meet the river basin needs expressed in the 2010 Neuse RBRP. Through stream restoration, the Project presents 3,719 LF of proposed stream, generating 3,719.000 Warm Stream Mitigation Units (SMUs). The Project Mitigation Quantities and Credits and Project Attributes are provided below in Table 1.

The past land use disturbances, absence of buffer vegetation, and current agricultural practices presented a significant opportunity for water quality and ecosystem improvements through the implementation of this Project. Through the comprehensive analysis of the Project's maximum functional uplift using the Stream Functions Pyramid Framework, specific, attainable goals and objectives are being realized by the Project. These goals clearly help to address the degraded water quality and nutrient input from agricultural practices that were identified as major watershed stressors in the 2010 Neuse River Basin Restoration Priorities (RBRP) (amended August 2018). Ultimately, the Project supports the RBRP Goals listed in the Approved Mitigation Plan. The Project Summary Goals, Performance, and Results are provided below in Table 2. The Project Attributes are found in Table 3.

The Strawberry Hill Project was built to design plans and guidelines. The record drawings are included in within the baseline report. There were no changes to the planting plan. However, as some high -quality tree species were found within the cutover areas that were timbered over eight years ago, these species were left in place where feasible. Minor monitoring device location changes were made during as -built installation, however, the quantities remained as proposed in the Mitigation Plan. 1.5 Monitoring Performance (MY1) The Strawberry Hill Year 1 Monitoring activities were performed in November 2022. All Monitoring data is presented below and in the appendices. The Project is on track to meeting stream and vegetation interim success criteria. 1.5.1 Vegetation Monitoring of the seven permanent vegetation plots and four random vegetation plots were completed November 16th, 2022. Vegetation data are in Appendix B, associated photos are in Appendix B, and plot Strawberry Hill Mitigation Project 3 Year 1 Monitoring Report - Stream Project 9100094 February 2023 locations are in Appendix A. MY 1 monitoring data indicates that all plots are exceeding the interim success criteria of 320 planted stems per acre. Planted stem densities ranged from 324 to 809 planted stems per acre with a mean of 578 planted stems per acre across all plots. A total of twelve planted species were documented within the plots. One volunteer species was identified in a random plot (Sambucus canadensis) and it is expected that more volunteers will establish in upcoming years. The average stem height in the vegetation plots was 1.5 feet. Visual assessment of vegetation outside of the monitoring plots indicates that herbaceous vegetation is establishing throughout the project area. 1.5.2 Stream H. d� y One stage recorder and one flow gauge are documenting conditions on reaches JH1-A and JH1-B, respectively. The stage recorder is in place to document bankfull events. The flow gauge is in place to document presence and persistence of stream flow in the intermittent channel. In addition, a camera rig (flow camera) was installed in conjunction with the flow gauge on JH1-A in the attempt to capture daily images of stream flow through the riffle. The stage recorder on JH1-B recorded four bankfull events in MY1 with the highest stage occurring on March 12t", 2022 and measuring 0.72 feet above top of bank. The flow gauge on JH1-A recorded 13 flow events with the longest consecutive flow event lasting 47 days between February 16t", 2022 and April 4t", 2022. o The flow camera was not installed until May 31d, 2022, therefore missing the most significant flow event. However, since its installation, it captured daily images and indicated several flow events, with the longest flow event lasting approximately 4 days between July 8th, 2022 and July 12t", 2022, which is ultimately a positive indication in the midst of a significant drought year. Appendix E presents rainfall and stream hydrology data, including tables, hydrographs, and flow camera photos. Gauge locations can be found on Figure 2 and photos are in Appendix A. 1.5.3 Stream Geomorphology Cross section setup and geomorphology data collection for MY was collected on November 16t", 2022. Summary tables and cross section plots are in Appendix C. Overall, there is very little change in cross sections, and they match the proposed design. MY1 conditions show that shear stress and velocities have been reduced for all restoration reaches. All reaches were designed as gravel bed channels and remain classified as gravel bed channels post -construction. Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. The channel is transporting sediment as designed and will continue to be monitored for aggradation and degradation (Appendix Q. Since Project construction, a suspected beaver dam has formed offsite, somewhere downstream of reach JH1-B and Brogden Road. This is causing some water to back up within the JH1-B channel near the road; however, most of the water is still contained within the channel and not causing any real inundation in the floodplain at this time. RES will continue to monitor the effect, but the suspected dam is offsite and not within the property of the Project's landowner.
