(Wildlands) implemented a full delivery project at the Martin Dairy Mitigation Project (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 is expected to generate 2,135 stream mitigation units (SMUs). All stream lengths were measured along the stream centerline for SMU calculations. 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 (HUC) 03020201. The project is located within a DMS targeted watershed for the Neuse River Basin Hydrologic Unit Code (HUC) 03020201030030 and NC Division of Water Resources (DWR) Subbasin 03-04-01. There are two unnamed tributaries on the Site, Martin Dairy Creek and UT1. The downstream drainage area of the Site is 526 acres. The Site drains to the Eno River which flows to Falls Lake and is classified as water supply waters (WS-IV). The 11.155-acre site is protected with a permanent conservation easement. The Site is located within the Neuse River Targeted Local Watershed (TLW) as presented in the 2010 Neuse River Basin Restoration Priorities (RBRP) (Breeding, 2010), which highlights the importance of riparian buffers for stream restoration projects. The Site was an active dairy farm until 2014 when livestock were removed, and the Site land use became hay cultivation. The project goals established in the mitigation plan (Wildlands, 2017) were developed considering the goals and objectives listed in the Neuse River RBRP plan. The project goals include: • Reconnect channels with floodplains and riparian wetlands to allow a natural flooding regime; • Improve the stability of stream channels; • Restore and enhance native floodplain and streambank vegetation; • Improve instream habitat; and • Permanently protect the Site from harmful land uses. The project will contribute to achieving the goals for the watershed listed in the Neuse River RBRP and provide ecological benefits within the Neuse River Basin. While benefits such as habitat improvement and geomorphic stability are limited to the Site, reduced nutrient and sediment loading have farther reaching effects. In addition, planned projects in the same watershed and basin as this Site will realize cumulative benefits. The Site construction and as-built surveys were completed between July 2017 and January 2018. Monitoring Year 2 (MY2) assessments and site visits were completed between May and September 2019 to assess the conditions of the project. Overall, the Site has met the required vegetation and stream success criteria for MY2. The overall average stem density for the Site is 405 stems per acre and is therefore on track to meet the MY3 interim requirement of 320 stems per acre. A significant die-off occurred in Vegetation Plot 7 causing the plot to not meet the MY3 interim requirement of 320 stems per acre; however, it is still above the MY7 final success criteria of 210 stems per acre. All restored streams are stable and functioning as designed. Hydrologic monitoring stations with crest gages and pressure transducers were installed on the Site to document bankfull events on the restoration reaches. Bankfull and geomorphically significant events were recorded on each restoration reach during the 2019 annual monitoring period. Since the Site also achieved these events during the 2018 annual monitoring period, the stream hydrology success criteria for bankfull events have been met.

The Site is located in the Neuse River Basin and within the Falls Lake Water Supply Watershed, which has been designated a Nutrient Sensitive Water. The project streams drain to the Eno River and eventually to the Falls Lake Reservoir. The Site is within Hydrologic Unit Code (HUC) 03020201030030, which is a Targeted Local Watershed (TLW) (Figure 1) as identified in the 2010 Neuse River Basin Restoration Priorities (RBRP) (Breeding, 2010). The Site is in in the Carolina Slate Belt of the Piedmont Physiographic Province (USGS, 1998). The project watershed consists primarily of agricultural and wooded land and the drainage area for project site is 526 acres (0.82 square miles). The project streams consist of Martin Dairy Creek and one unnamed tributary. Stream restoration reaches included Reaches 1 and 2 of Martin Dairy Creek and UT1. Mitigation work within the Site included restoration of 2,135 linear feet (LF) of perennial stream channels. The riparian areas were planted with native vegetation to improve habitat and protect water quality. The final mitigation plan (Wildlands, 2017) was submitted to and accepted by the DMS in March 2017. Construction activities were completed by Land Mechanic Designs, Inc. in July 2017. Planting and seeding activities were completed by Bruton Natural Systems, Inc. in December 2017. Baseline monitoring (MY0) was conducted between August 2017 and January 2018. Monitoring Year 1 was conducted in 2018. Annual monitoring will occur for seven years with the close-out anticipated to occur in 2025 given the success criteria are met. Appendix 1 provides additional details on project activity, history, contact information, and watershed/background information for the Site. The Site is located on two tracts under the ownership of Ted H. Martin (PIN 9896-83-0483 & 9896-83- 9111). A conservation easement was recorded on 11.155 acres (Deed Book 6218, Pages 270 - 289). The project is expected to provide 2,135 stream mitigation units (SMUs) by closeout. A project vicinity map and directions are provided in Figure 1 and project components/assets are illustrated in Figure 2. 1.1 Project Goals and Objectives Prior to construction activities, the primary degradation at the Site was the clearing of vegetation and channelization of Martin Dairy Creek and UT1. Channelization, as indicated by dredge spoil in the floodplain, involved straightening and deepening of the stream. Livestock grazing on the Site further contributed to degradation of the riparian corridor and stream channel. Table 4 in Appendix 1 and Tables 10a and 10b in Appendix 4 present the pre-restoration conditions in detail. The project is intended to provide numerous ecological benefits within the Neuse River Basin. While benefits such as habitat improvement and geomorphic stability are limited to the project site, reduced nutrient and sediment loading have farther reaching effects. The table below, describes expected outcomes to water quality and ecological processes are provided with project goals and objectives. The project goals and objectives were developed as part of the mitigation plan considering the goals and objectives listed in the Neuse River RBRP plan and strive to maximize ecological and water quality uplift within the watershed. The following project goals and related objectives established in the Mitigation Plan (Wildlands, 2017) include: Martin Dairy Mitigation Site Monitoring Year 2 Annual Report - Final 1-2 Goal Objective Expected Outcomes Reconnect channels with floodplains and riparian wetlands to allow a natural flooding regime. Reconstruct stream channels with designed bankfull dimensions and depth based on reference reach data. Remove existing dredge spoil to reconnect channel with adjacent wetlands. Raise water table and hydrate riparian wetlands. Allow more frequent flood flows to disperse on the floodplain. Support geomorphology and higher level functions. Improve the stability of stream channels. Construct stream channels that will maintain stable cross- sections, patterns, and profiles over time. Reduce sediment inputs from bank erosion. Reduce shear stress on channel boundary. Support all stream functions above hydrology. Restore and enhance native floodplain and streambank vegetation. Plant native tree and understory species in riparian zones and plant native shrub and herbaceous species on streambanks. Reduce sediment inputs from bank erosion and runoff. Increase nutrient cycling and storage in floodplain. Provide riparian habitat. Add a source of LWD and organic material to stream. Support all stream functions. Improve instream habitat. Install habitat features such as constructed riffles, lunker logs, and brush toes into restored streams. Add woody materials to channel beds. Construct pools of varying depth. Increase and diversify available habitats for macroinvertebrates, fish, and amphibians leading to colonization and increase in biodiversity over time. Add complexity including LWD to the streams. Permanently protect the Site from harmful uses. Establish a conservation easement on the Site. Protect the Site from encroachment on the riparian corridor and direct impact to streams and wetlands. Support all stream functions. 1.2 Monitoring Year 2 Data Assessment Annual monitoring and site visits were conducted during MY2 to assess the condition of the project. The vegetation and stream success criteria for the Site follow the approved success criteria presented in the mitigation plan. 1.2.1 Vegetative Assessment Planted woody vegetation is being monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008). A total of eight standard 10-meter by 10-meter vegetation plots were established during the baseline monitoring within the project easement area. The final vegetative success criteria is the survival of 210 planted stems per acre at the end of the seven- year monitoring period (MY7). The interim measure of vegetative success is the survival of at least 320 planted stems per acre at the end of year three of the monitoring period (MY3) and at least 260 stems per acre at the end of the fifth year of monitoring (MY5). Planted vegetation must average 10 feet in height at the end of MY7. Martin Dairy Mitigation Site Monitoring Year 2 Annual Report - Final 1-3 The MY2 vegetative survey was completed in September 2019. The 2019 vegetation monitoring resulted in an average stem density of 405 stems per acre, which is well above the interim requirement of 320 stems per acre required at MY3 and 32% less than the baseline density recorded (597 stems per acre). There is an average of 10 stems per plot in MY2 compared to 14 stems per plot in MY0. With 283 planted stems per acre, Vegetation Plot 7 is not on track to meet the interim requirement of 320 stems per acre but it is still above the final vegetative success criteria of 210 planted stems per acre. The reason for Vegetation Plot 7’s tree mortality is that Alligator weed (Alternanthera philoxeroides) has formed a thick herbaceous understory that has out competed the planted trees. However, several volunteer species including green ash (Fraxinus pennsylvanica) and buttonbush (Cephalanthus occidentalis) were recorded in the plot, increasing the total stems per acre to 405. Thus, all eight of the plots are on track to meet the success criteria required for MY7. Refer to Appendix 2 for vegetation plot photographs and the vegetation condition assessment table and Appendix 3 for vegetation data tables. 1.2.2 Vegetation Areas of Concern Vegetation Plot 7 had a higher planted tree mortality rate than the rest of the vegetation plots on Site due to competition from Alligator weed. Even with a dense herbaceous layer, volunteers are surviving, increasing the stems per acres to 405. Due to the success of the volunteer trees, remedial action will not be taken in MY3 but monitoring will continue to assess tree mortality rates. Tree vigor along UT1 was good but is not performing as well as the rest of the Site. This is likely due to floodplain grading during construction. Approximately 100 pounds of biochar, rock phosphate, azomite, and humic acid was added to the floodplain to promote tree growth during MY2. Remedial action will be taken as necessary in subsequent monitoring years to promote tree growth. 1.2.3 Stream Assessment Morphological surveys for MY2 were conducted in May 2019. All streams within the Site are stable and functioning as designed. In general, cross-sections at the Site show little to no change in the bankfull area, maximum depth ratio, or width-to-depth ratio. Bank height ratios are less than 1.1. Substrate materials indicate the maintenance of coarser materials in the riffle reaches and finer particles in the pools. Longitudinal profile surveys are not required on the project unless visual inspection indicates reach wide vertical instability. Refer to Appendix 2 for the visual stability assessment table, Current Condition Plan View (CCPV) map, and stream photographs. Refer to Appendix 4 for the morphological data and plots. 1.2.4 Stream Areas of Concern No stream areas of concern were identified during MY2. 1.2.5 Hydrology Assessment At the end of the seven-year monitoring period, two or more bankfull events must have occurred in separate years within the restoration reaches. Also, two geomorphically significant events must be documented during the monitoring period. Bankfull events and multiple geomorphically significant events were recorded on all restoration reaches during MY1 and MY2, resulting in attainment of the stream hydrology success criteria. Refer to Appendix 5 for hydrologic data. 1.2.6 Maintenance Plan No maintenance plan is necessary at this time. Martin Dairy Mitigation Site Monitoring Year 2 Annual Report - Final 1-4 1.3 Monitoring Year 2 Summary Seven of the eight vegetation plots are on track to meet the MY3 interim requirement of 320 planted stems per acre. Vegetation Plot 7 had significant tree mortality due to competition from alligator weed but is still above the final success requirement of 210 planted stems per acre. When counting volunteer trees, vegetation plot 7 is above the MY3 interim requirement. All streams within the Site are stable and functioning as designed. Bankfull and geomorphically significant events during two separate years have been documented on all stream reaches, resulting in fulfillment of the stream hydrology success criteria. Summary information and 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 available on DMS’s website. All raw data supporting the tables and figures in the appendices are available from DMS upon request. Martin Dairy Mitigation Site Monitoring Year 2 Annual Report - Final 2-1 Section 2: METHODOLOGY Geomorphic data was collected following the standards outlined in The Stream Channel Reference Site: An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in Stream Restoration: A Natural Channel Design Handbook (Doll et al., 2003). All Integrated Current Condition Mapping was recorded using a Trimble handheld GPS with sub-meter accuracy and processed using Pathfinder and ArcGIS. Crest gages and pressure transducers were installed in riffle cross-sections and monitored throughout the year. Hydrologic monitoring instrument installation and monitoring methods are in accordance with the United States Army Corps of Engineers standards (USACE, 2003). Vegetation monitoring protocols followed the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008).
