DEPARTMENT OF ENVIRONMENTAL QUALITY DIVISION OF MITIGATION SERVICES 1601 MAIL SERVICE CENTER RALEIGH, NORTH CAROLINA 27699-1601 FINAL MONITORING REPORT YEAR 6 (2023) MUD LICK CREEK MITIGATION SITE Chatham County, North Carolina NCDMS Project No. 93482 Contract No. 7683 USACE Action ID No. SAW-2014-00736 & DWR Project No 2014-1127 SCO No. 1209857-01 Data Collection: April-September 2023 Submission: February 2024 PREPARED BY: AXIOM ENVIRONMENTAL, INC. 218 SNOW AVENUE RALEIGH, NORTH CAROLINA 27603 2023 MY6 Annual Monitoring Report (Final) Executive Summary page i Mud Lick Creek Mitigation Site (DMS Project # 93482) PROJECT SUMMARY The North Carolina Division of Mitigation Services (NCDMS) has established the Mud Lick Creek Mitigation Site (Site) located within the Cape Fear River Basin Cataloging Unit (CU) 03030003 in the Upper Rocky River local watershed planning (LWP) area and 14-digit HUC 03030003070010. The Site was identified as a priority mitigation project in the Detailed Assessment and Targeting of Management Report (Tetra Tech 2005). The main stressors to aquatic resources identified during the watershed assessments described in the LWP documents include the following.  Nutrient (nitrogen and phosphorous) loading from farming;  Sediment loading from overland runoff, disturbed surfaces, and streambank erosion;  Cattle access to streams increasing bank erosion and fecal coliform contamination; and  Insufficient bank vegetation. The project will contribute to meeting management recommendations to offset these stressors as described above for the LWP area by accomplishing the following primary goals.  Control and reduce nutrient sources from the Site;  Reduce sediment loads from disturbed areas on the Site and from eroding stream banks;  Increased aeration of flows within the project extent promoting increases in dissolved oxygen concentrations;  Reduce sources of fecal coliform pollution;  Improve instream habitat;  Reduce thermal loadings;  Reconnect channels with floodplains and raise local water table; and  Restore riparian habitat. These goals will be accomplished through the following objectives:  Restore riparian vegetation on the Site and thereby reduce sediment loads to streams from stream banks and existing pastures, increase on-Site retention of sediment and nutrients, create riparian habitat, and provide shade for streams to reduce thermal loadings;  Stabilize eroding streambanks to reduce sediment inputs;  Install fencing around the perimeter of the conservation easement to eliminate livestock access to streams, thereby reducing sediment, nutrient, and fecal coliform inputs;  Plant restored and stabilized streambanks with native species to improve stability and habitat;  Install instream structures to improve stability, create habitat, and help aerate stream flows;  Raise streambeds to reconnect restored channels to floodplains and raise local water tables; and  Restore streams and vegetation so the Site looks natural and aesthetically pleasing. Stream Success Criteria: The stream restoration performance criteria for the Site will follow approved performance criteria presented in the 2015 Mud Lick Creek Mitigation Site Final Mitigation Plan as described below. Stream Dimension: Riffle cross-sections on the restoration reaches and enhancement II reaches, where banks were re-graded (three reaches of Mud Lick Creek), should be stable and should show little change in bankfull area, maximum depth, and width-to-depth ratio. Bank-height-ratios shall not exceed 1.2 and entrenchment ratios shall be at least 2.2 for restored channels to be considered stable. All riffle cross- sections should fall within the parameters defined for channels of the appropriate stream type. 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 2023 MY6 Annual Monitoring Report (Final) Executive Summary page ii Mud Lick Creek Mitigation Site (DMS Project # 93482) 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. Stream Pattern and Profile: The as-built survey will include a longitudinal profile for the baseline monitoring report. 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. Substrate: Substrate materials in the restoration reaches should indicate a progression towards or the maintenance of coarser materials in the riffle features and smaller particles in the pool features. Hydraulics: Two bankfull flow events, in separate monitoring years, must be documented on the restoration reaches and enhancement II reaches where banks were re-graded (three reaches of Mud Lick Creek) within the seven-year monitoring period. Vegetation Success Criteria: The final vegetative success criteria will be the survival of 210 planted stems per acre in the riparian corridor along restored and enhanced reaches at the end of the required monitoring period (year seven). The interim measure of vegetative success for the Site will be the survival of at least 320 planted stems per acre at the end of the third monitoring year and at least 260 stems per acre at the end of the fifth year of monitoring. If this performance standard is met by year five and stem density is trending towards success (i.e., no less than 260 stems/acre), monitoring of vegetation on the Site may be terminated with written approval by the USACE in consultation with the NC Interagency Review Team. The extent of invasive species coverage will also be monitored and controlled as necessary throughout the required monitoring period (seven years). Photo Documentation: Photographs should illustrate the Site’s vegetation and morphological stability on an annual basis. Cross-section photos should demonstrate no excessive erosion or degradation of the banks. Longitudinal photos should indicate the absence of persistent bars within the channel or vertical incision. Grade control structures should remain stable. Deposition of sediment on the bank side of vane arms is preferable. Maintenance of scour pools on the channel side of vane arms is expected. Visual Assessments: Visual assessments should support performance standards as described above. As per Sections 7.2 and 12.4 of the Mitigation Plan, physio-chemical and biological parameters were included as part of specialized monitoring, depending on the data that could be obtained during the baseline period. Monitoring of these parameters was for investigative purposes only and not tied to mitigation success or credit. The sample size and variability of the pre-construction physio-chemical data was inadequate for the purposes of post-construction comparison and therefore, these will not be monitored moving forward. However, fish and macrobenthos will be monitored at the stations indicated in the asset and monitoring features map (Figure 2, Appendix B). Site Background: The Site is located in northwestern Chatham County, north of Siler City and northwest of Silk Hope (Figure 1, Appendix B). The Site is located within United States Geological Survey (USGS) Hydrologic Unit and Targeted Local Watershed 03030003070010 (North Carolina Division of Water Resources Subbasin 03-06-12) of the Cape Fear River Basin. Prior to construction, the Site was used for agricultural livestock production. The proposed project will improve water quality as well as provide numerous ecological benefits within the Cape Fear River Basin. The project will help meet management recommendations of the Upper Rocky River Local Watershed Plan by restoring a vegetated riparian buffer zone, stabilizing eroding stream banks, and removing livestock from streams and riparian zones. These activities will result in reduced nutrient, sediment, and fecal coliform inputs; improved aquatic and riparian habitat, and other ecological benefits. 2023 MY6 Annual Monitoring Report (Final) Executive Summary page iii Mud Lick Creek Mitigation Site (DMS Project # 93482) Mitigation Components: Project mitigation efforts will generate 2832 Stream Mitigation Units (SMUs) as the result of the following (Table 1, Appendix A & Figure 2, Appendix B).  Restoration of 1215 linear feet of Site streams  Enhancement (Level II) of 2426 linear feet of Site streams Site design was completed in June 2015. Site construction occurred May 24–August 25, 2017 (final walkthrough) and the Site was planted in February 2018. Completed project activities, reporting history, completion dates, project contacts, and project attributes are summarized in Tables 1-4 (Appendix A). The assets and credits in the report, and shown in Table 1, are based upon approved as-built numbers as approved by the IRT on 11/1/2018. 2023 MY6 Annual Monitoring Report (Final) Table of Contents page i Mud Lick Creek Mitigation Site (DMS Project # 93482) TABLE OF CONTENTS 1.0 METHODS ....................................................................................................................................... 1  2.0 REFERENCES ................................................................................................................................. 5  APPENDICES Appendix A.

Monitoring is proposed for the stream channel and vegetation. In general, the restoration success criteria, and required remediation actions, are based on the Stream Mitigation Guidelines (USACE et al. 2003). Monitoring features are summarized in the following table and described below; monitoring features are depicted on Figure 2 (Appendix B). Monitoring Summary Parameter Monitoring Feature Quantity Frequency Streams Dimension Cross-sections 7 riffles & 3 pools annually Substrate Pebble counts 3 riffles annually Hydrology Crest gauges 3 annually Vegetation Vegetation Plots 12 annually Warranty Plots 10 MY1 Visual assessments Entire Site biannually Exotic & nuisance species Entire Site annually Project boundary Entire Site annually Reference photographs 22 annually Supplemental Monitoring Biological Macrobenthos 5 sites (Preconstruction only) 3 sites (MY3, MY5, & MY7) Fish 3 sites (Preconstruction only) 2 sites (MY4 & MY7) Streams The restored stream reaches are proposed to be monitored for geometric activity as follows.  7 permanent riffle cross-sections  3 permanent pool cross-sections  3 riffle pebble count samples for substrate analysis  3 stream crest gauges The data will be presented in graphic and tabular format. Data to be presented will include 1) cross- sectional area, 2) bankfull width, 3) average depth, 4) maximum depth, and 5) width-to-depth ratio. Substrate analysis will be evaluated through pebble counts at three riffle cross-sections and data presented as a D50 for stream classification and tracking purposes. The stream will subsequently be classified according to stream geometry and substrate (Rosgen 1996). Significant changes in channel morphology including bank-height-ratios and entrenchment ratios will be tracked and reported by comparing data to asbuilt measurements in addition to each successive monitoring year. Annual photographs will include 22 fixed station photographs (12 vegetation plots and 10 cross-sections) (Appendix B). The Site contains three stream crest gauges to assist with documentation of bankfull events. One bankfull event was documented during monitoring year 6 (2023), making a total of seven bankfull events documented over the monitoring period to date (Table 13, Appendix E). Year 6 cross-section data indicate little change from as-built conditions and that the streams are functioning as designed, overall, with the exception of cross-section 2, a riffle on Mud Lick Creek. Pool cross-sections, 2023 MY6 Annual Monitoring Report (Final) Page 2 Mud Lick Creek Mitigation Site (DMS Project # 93482) such as cross-section 8, are typically not monitored for bank-height-ratio because they are naturally sediment storage and transport areas within a stream. This is apparent in review of the varying Dmax and LBH values exhibited by cross-section 8 throughout the monitoring period. Bank erosion has not been noted within or adjacent to cross-section 8, and overall, the reach appears stable. Cross-section 1 has been characterized by increased bank height ratio for the past several monitoring years. It is located within an Enhancement (Level II) reach of stream that has scoured in previous years; however, the scour appears to have been minimized and the channel has reformed natural top-of-bank indicators within the dimensional parameters of the channel. Cross-section 1 has remained relatively consistent and stable for the past 3 monitoring years. Cross-section 2 has an increased bank-height ratio of 1.29 due to heavy scouring along the inner bend (right bank). This scour was first observed during year 2 (2019) but remained stable through year 5 (2022). It appears the scour was increased by beaver activity during year 6, and it is now considered an area of concern. All site cross-sections, except for cross-section 2, meet success criteria during year 6 (2023). Three stream areas of concern were observed during monitoring year 6 (2023), two of which were documented during previous monitoring years. Stream Area of Concern #1 is located along Mud Lick Creek R2 where approximately 50 feet of the right bank and 20 feet of the left bank have eroded to the point of bank sloughing. This area has only slightly increased in size due to the erosive nature of the soils, lack of woody vegetation, and continued storm flows. Stream Area of Concern #2 consists of scouring and sloughing along an outer bend along Mud Lick Creek R3, immediately downstream from cross-section 1. This was initially attributed to significant storm events that occurred during 2018, however, subsequent high discharge events have continued to erode the outer bend. Stream area of Concern #3 consists of the aforementioned scour on the inner bend at cross-section 2; approximately 30 feet in total. All stream areas of concern are located within enhancement II reaches. No areas of erosion or instability were observed in restoration reaches of North and East Branch. All structures were stable and banks were well-vegetated with live stakes and herbaceous vegetation. All stream reaches generating restoration credit are functioning as designed and are stable throughout. Stream areas of concern are depicted on Figure 2 in Appendix B. Vegetation Restoration monitoring procedures for vegetation health will monitor plant survival and species diversity. After planting of the area was completed, 12 permanent vegetation plots were installed and monitored at the Site; annual results are in Appendix C. Annual measurements of vegetation will consist of the following.  10 plant warranty inspection plots (only MY1)  12 CVS vegetation plots A photographic record of plant growth should be included in each annual monitoring report; vegetation plot photographs from year 6 (2023) are included in Appendix B. During the first year, vegetation will receive a cursory, visual evaluation on a periodic basis to ascertain the degree of overtopping of planted elements by nuisance species. Subsequently, quantitative sampling of vegetation will be performed as outlined in the CVS-EEP Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008) in late fall/early winter of the first monitoring year and annually toward the end of the growing season for the remainder of the monitoring period until vegetation success criteria are achieved. Year 6 (2023) stem count measurements for twelve permanent CVS plots indicate the planted stem density across the Site is 270 planted stems per acre, exceeding the Year 7 stem density success criteria of 210 stems per acre. Nine of the twelve individual CVS plots met success criteria based on planted stems alone; however, when including naturally recruited stems of American elm (Ulmus americana) and American 2023 MY6 Annual Monitoring Report (Final) Page 3 Mud Lick Creek Mitigation Site (DMS Project # 93482) sycamore (Platanus occidentalis), the stem densities of plots 6 and 11 are above success criteria. Plot 1 was one stem shy of success. This plot experienced mortality of two stems between MY3 and MY4 and one more between MY4 and MY5. There are no natural recruits in the plot (Table 9, Appendix C). Plot 11 is dominated by dense herbaceous vegetation and high numbers of naturally recruited American sycamore (Platanus occidentalis), increasing competition with planted stems. Additionally, several small but dense populations of Chinese privet (Ligustrum sinense) and tree of heaven (Ailanthus altissima) were observed scattered throughout the Site. Although invasive treatments have been ongoing, these areas remain previous years. Invasive species populations are depicted on Figure 2 (Appendix B). Due to decreasing Site stem density and continued observation of deer browse and competition with herbaceous species, DMS implemented an adaptive management that includes supplementally planting 1- and 3-gallon containerized trees across 2.04 acres of the Site. Supplemental planting areas are depicted on Figure 2 (Appendix B), the supplemental planting list is in Table 8 (Appendix C), and the adaptive management plan is detailed in Appendix F. As a part of the adaptive management plan, three temporary transects were requested by the DMS in areas that were replanted. All three transects met success criteria with an average of 418 stems per acre. Transect locations are depicted on Figure 2 (Appendix B), and results are in Table 10 (Appendix C). Project Boundaries & Visual Assessments Locations of any fence damage, vegetation damage, boundary encroachments, etc. will be documented and included in the mapping. No boundary encroachments were observed during Year 6 (2023) monitoring. Visual assessments will be performed along all streams on a bi-annual basis during the seven-year monitoring period. Problem areas will be noted such as channel instability (i.e. lateral and/or vertical instability, in-stream structure failure/instability and/or piping, headcuts), vegetated buffer health (i.e. low stem density, vegetation mortality, invasive species or encroachment), beaver activity, or livestock access. Areas of concern will be mapped and photographed accompanied by a written description in the annual report. Problem areas will be re-evaluated during each subsequent visual assessment. Results of the year 6 (2023) visual assessment are summarized in Tables 5A-C and 6 (Appendix B). During year 3 (2020) monitoring, onsite beaver activity was observed including a significant dam along North Branch R3, a dam along Mud Lick Creek R2, and several smaller dams throughout the Site. In response, on November 4, 2020, USDA trapped beavers and removed six dams. A small beaver dam was observed during year 5 (2022) along North Branch R2. The stream was dry at the time of assessment, therefore, it was unclear if there were active beaver populations still within the site. During year 6 (2023), a large beaver dam was located just downstream of XS-5 on North Branch R2. Most of the dam was removed, but there was a large beaver lodge in the vicinity of the dam. It was unclear if there is still an active beaver population on the site, and perhaps the dam was overlooked during beaver trapping efforts. APHIS was contracted in 2023 to visit the site quarterly and manage beaver as necessary through project closeout. Supplementary Monitoring Supplemental monitoring will include biological monitoring in the Spring as follows.  3 benthos sampling sites (MY3, MY5, & MY7)  2 fish sampling sites (MY4 & MY7) Additional parameters are being monitored for analytical purposes and are not tied to mitigation success and associated credit releases. The primary criteria for indication of improvement for the benthos and fish will be an increase of at least one bio classification between the pre-con assessment and the post-con 2023 MY6 Annual Monitoring Report (Final) Page 4 Mud Lick Creek Mitigation Site (DMS Project # 93482) monitoring. Richness and EPT metrics will be analyzed as well. Based on values tabulated on Habitat Assessment Field Data Sheets, benthic macroinvertebrate habitat appears to be improving at the Site. Overall values for the data sheets have improved by 10 to 54 points since preconstruction. In addition, each independent variable on the data sheets has shown improvement over the monitoring period, except for channel modification. Biotic index (tolerance of a stream benthic community) has not shown significant improvement with station MLC-2 shifting from a Fairly Poor to Very Poor designation, station MLC-3 shifting from Poor to Very Poor, and station NBR-5 remaining within the Poor range. A summary of benthic results including Habitat Field Data Assessment Sheet scores and Biotic Index values from laboratory analysis results (preconstruction to MY5) is presented below.

Adaptive Management Attachment 1: Adaptive Management Plan MEMORANDUM DATE: October 25, 2022 TO: IRT Members FROM: DMS, Jeremiah Dow RE: Mud Lick Creek Project Request for IRT Approval of Adaptive Management Plan for Supplemental Planting Mud Lick Creek is a design-bid-build stream project that was instituted on 2/13/2013. Wildlands Engineering, Inc. prepared the mitigation plan in 2015 and Axiom Environmental, Inc. was contracted to perform project monitoring. In 2021 DMS contracted Michael Baker Engineering, Inc. (Baker) to manage invasive and nuisance vegetation. Baker will also provide the supplemental planting services. The project is currently in monitoring year 5. In MY4, four veg plots – 1, 6, 10, & 11 – out of 12 plots did not meet success criteria On 6/4/2021, the IRT and DMS conducted a credit release site visit where areas of low density and/or low vigor were identified. No additional management activities were prescribed at that time and the IRT recommended continued monitoring of problematic areas with an understanding that supplemental planting may be necessary. Baker was contracted to manage fescue in low vigor areas and thin sweet gum on the eastern side of the project to reduce competition with existing planted stems. On August 30, 2022 DMS personnel visited the site to assess the invasive and nuisance vegetation management efforts and low stem density/vigor areas. During that site visit it was determined that supplemental planting would be necessary, and targeted planting areas were mapped with GPS. Due to competition with dense herbaceous vegetation and sweet gum, and evidence of widespread deer browse, it was decided that the site should be supplementally planted with 1 gallon and 3 gallon containerized trees. Proposed planting list is attached. All listed species are from the approved Mitigation Plan. 2.04 acres are proposed for supplemental planting out of 9.6 total acres planted which accounts for 21% of the total planted area. Supplemental planting will include the following: Size Species Quantity 3 Gall. Fraxinus pennsylvanica (Green Ash) 50 3 Gall. Platanus occidentalis (Sycamore) 50 3 Gall. Populus deltoides (E. Cottonwood) 50 3 Gall. Betula nigra (River Birch) 50 3 Gall. Sambucus canadensis (Elderberry) 50 1 Gall. Cornus amomum (Silky Dogwood) 50 1 Gall. Hamamelis virginiana (Witch Hazel) 50 1 Gall. Diospyros virginiana (Persimmon) 50 3 Gall. Quercus michauxii (Swamp Chestnut Oak) 50 3 Gall.
