(Wildlands) implemented a full delivery project at the Martin Dairy Mitigation Site ("Site") for the North Carolina Department of Environmental Quality Division of Mitigation Services (DMS) to restore a total of 2,135 linear feet (LF) of perennial streams in Orange County, NC. The Site included the restoration of two unnamed tributaries (Martin Dairy Creek and UT1). The project also restored 10.139 acres (441,654.84 ft2) of riparian buffer at the Site, which will provide 379,169.330 riparian buffer credits. The project Site was planned, designed, and constructed on land surrounding Martin Dairy Creek and its tributary. The Site is located approximately eight miles northeast of Hillsborough, NC and eight miles south of Caldwell, NC (Figure 1) in the Neuse River Basin 8-Digit Hydrologic Unit Code 03020201. The project is located within the Neuse River Basin Hydrologic Unit Code 03020201030030 and NC Division of Water Resources (DWR) Subbasin 03-04-01. The Site drains to Buckwater Creek, which flows to Falls Lake, which is classified as Water Supply Waters (WS-IV) and Nutrient Sensitive Waters (NSW). The 11.155 acre Site is protected with a permanent conservation easement. The project has been planned, designed, and constructed per the Martin Dairy Mitigation Plan (Wildlands, 2017) and the Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 (effective November 1, 2015). The purpose of the riparian buffer restoration is to provide riparian buffer credits to compensate for buffer impacts within the Hydrologic Unit Code 03020201 and the Falls Lake Watershed. The service area for the riparian buffer credits is depicted in Figure 2. The mitigation credits generated from this Site are listed in Table 1 and shown in Figure 3. 1.2 Project Goals and Objectives Prior to construction activities, the primary degradation on the Site was the original clearing of the Site and channelization of Martin Dairy Creek and UT1. The channelization involved straightening and deepening of the stream (as indicated by the amount of dredge spoil in the floodplain). In the past livestock were grazed on the Site, which contributed to bank sloughing. Table 4 in Appendix 1 presents the pre -restoration conditions in more detail. The restored riparian buffer areas within the Site will aid in protecting water quality. The main objective of the project was to reduce nitrogen and phosphorus loading to the Neuse River tributaries by establishing a forested riparian buffer on land previously used for agricultural purposes. The riparian buffer will immobilize nutrients, reducing quantities available to downstream aquatic ecosystems in the Neuse River Basin. The Site is protected with a 11.155 acre conservation easement. Out of the 11.155 acres, 10.139 acres were restored for Neuse River buffer credit and 1.017 acres will not generate buffer mitigation credit. In general, riparian buffer restoration area widths on streams extend out to 200 feet from top of bank for Neuse River buffer credits. Maps detailing the credit generation are provided in Figure 3. 1.3 Monitoring Year 4 Data Assessment The final Mitigation Plan was submitted and accepted by DMS in March 2017. Construction activities were completed by Land Mechanic Designs, Inc in July 2017. The planting was completed by Bruton Natural Systems, Inc. in December 2017. The baseline as -built survey for the stream mitigation work was completed by Turner Land Surveying in August 2017 and for the buffer mitigation component in January 2018. Monitoring Year 4 vegetation survey was completed September 2021. Refer to Appendix 1 for detailed project activity, history, contact information, and watershed/site background information. Martin Dairy Buffer Mitigation Site Monitoring Year 4 Annual Report - Final Vegetative performance for buffer restoration areas will be in accordance with 15A NCAC 02B .0295(n)(2)(B), and (n)(4) (effective November 1, 2015). To meet success criteria, areas generating buffer mitigation credits shall include a minimum of four native hardwood tree species or four native hardwood tree and native shrub species, where no one species is greater than 50 percent of stems, and have a survival of 260 planted stems per acre at the end of the required monitoring period (MY5) (no interim success criteria required). In order for the monitoring to be terminated, DWR must provide written approval of vegetation success of the buffer restoration areas generating buffer credit. Annual monitoring was conducted to assess the condition of the vegetation in September 2021. 1.3.1 Vegetative Assessment The quantity of monitoring vegetation plots was determined in accordance with the Carolina Vegetative Sampling Protocol (CVS Levels II) such that at least two (2) percent of the Site is encompassed in monitoring plots. A total of eight (8) vegetation plots (10 meters by 10 meters) were randomly established between the conservation easement boundaries and five feet from the top of stream banks. The plot corners have been marked and are recoverable either through field identification or with the use of a GPS unit. Reference photographs will be taken at the origin looking diagonally across the plot to the opposite corner on an annual basis. Species composition, density, and survival rates will be evaluated on an annual basis by plot and for the entire site. The extent of invasive species coverage will also be monitored and controlled as necessary. The MY4 vegetative survey was completed in September 2021. All eight of the vegetation plots exceeded the MY5 success criteria with an average stem density of 435 planted stems per acre. Individual plots ranged from 364 to 486 stems per acre. All plots surpassed the density requirements for MY5 by at least 47%. Volunteer species are flourishing and have shown an overall increase in both species diversity, and density. The MY4 average stem density including volunteer species has risen to 1,108 stems per acre, which is nearly 50% higher than MYO. Refer to Appendix 3 for vegetation plot criteria attainment data, CVS vegetation plot metadata, and vegetation summary tables and Appendix 2 for vegetation plot photographs, vegetation condition assessment table, and monitoring plan view. Tree vigor and vegetative cover along UT1 has immensely improved from MY3. Container trees and tublings planted in MY3 have thrived and vegetative and herbaceous cover has benefited from the addition of soil amendments. The effects of the supplemental planting done during the prior year can be seen through improvements in stem density across the Site. Deer browse has limited the height of trees throughout the Site. Repellex pellets containing capsacin will be added at the base of trees in attempt to deter deer from browsing. 1.4 Monitoring Year 4 Summary All eight vegetation plots are on track to surpass the success criteria at the end of MY5. Remedial efforts taken in the prior monitoring year have greatly benefited the Site's overall vegetative success. The density of both volunteer and planted trees have increased from MY3. The Site has shown positive trends of vegetative growth and establishment and is expected to continue these trends during the upcoming monitoring year. Herbaceous vegetation is thriving, and species diversity and abundance has increased across the site. Summary information/data related to the 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 Mitigation Plan documents available on Martin Dairy Buffer Mitigation Site Monitoring Year 4 Annual Report - Final 3 DMS's website. All raw data supporting the tables and figures in the appendices is available from DMS upon request. Section 2: METHODOLOGY Planted woody vegetation was monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2006). A total of eight standard 10 meter by 10-meter vegetation plots were established within the project easement area. Section 3: REFERENCES Breeding, R. 2010. Neuse River Basin Restoration Priorities.
