The project is located in northwest Robeson County, approximately 6 miles north of Maxton, off Modest Rd (Figure 1). This project includes rehabilitation of non -riparian wetlands and preservation of existing forested and ponded wetlands (Table 1). The Project site is a former agricultural field, located on an inter -stream divide between the Lumber River and Black Gum Swamp, surrounded by forested areas and agricultural parcels. The site was altered since the mid -80s, which included ditching and clearing. The site contains approximately 9.940 acres exhibiting wetland hydrology and soils (Wetland 1), but initially was lacking in hydrophytic vegetation, lending itself to a rehabilitation restoration approach using the definitions provided in 40 CFR Part 230 (Final Rule). Additionally, there are two jurisdictional wetland communities on the site, as confirmed by an approved jurisdictional determination (JD) by the US Army Corps of Engineers on January 6, 2016, leading to a preservation approach to provide wetland restoration equivalents (RE). These preservation areas include 23.042 acres of a successional wetland and forested hardwood flat in the Southern section of the project (Wetland 2) and 51.382 acres of forested hardwood flat/pocosin and open water/wetland habitat in the northern section of the project, for a total of 74.424 acres of preservation (Figure 2). These acreages have been updated from the Mitigation Plan to As -Built stage due to GIS geometry calculation. Wetland restoration activities included planting the rehabilitation areas in March 2016 with 5,010 bare root species from the Hardwood Flat Forest Community (NCWAM, v. 4.12010) as well as other similar species found in the adjacent forested wetland community. There were six (6) different species selected to reflect the target vegetative community. 1.1 Goals and Objectives The Lumber River Basin Restoration Priorities state that the goals for the Black Gum Creek 14 -digit HUC are: • Replacing buffer • Repairing channelized streams • Preservation of existing resources. The following specific project goals, as stated in the Mitigation Plan, include: • Restoring a hardwood flat vegetation community • Expanding forested wetland complex The success of these project goals will be addressed through the following objectives: • Plant native tree/shrub species • Preserve existing hardwood flat/pocosin wetlands 2.0 PERFORMANCE STANDARDS 2.1 Vegetation An average density of 260 stems/acre must be surviving after five years of monitoring. Upon completion of planting in March 2016, eight (8) permanent vegetation plots were installed and initial plant stocking was performed to determine species composition and density (Appendix C, Table 6). Vegetation was monitored using the Carolina Vegetation Survey (CVS) protocols level 2 monitoring. Year 3 Annual Monitoring Report Black Gum Creek 97063 4 2.2 Hydrology The site will present continuous saturated or inundated hydrologic conditions for at least 8% of the growing season during normal weather conditions. A "normal' year is based on NRCS climatological data for Robeson County, using the 30th to 70th percentile thresholds as the range of normal. The growing season for Robeson County, using the 50% chance of higher than 28 F method, is from March 22th through November 5th, 228 days (WETS Table, Robeson County). Hydrologic performance will be determined through evaluation of automatic recording gauge data supplemented by documentation of wetland hydrology indicators as defined in the 1987 USACE Delineation Manual, daily data will be collected from automatic wells over the 5 -year monitoring period. Five (5) continuous monitoring groundwater gauges were installed to provide pre -restoration conditions, and data was downloaded to provide one more year of pre -restoration data for this as -built report. Data from the 2018 growing season is provided in Appendix D. 3.0 MONITORING PLAN Annual monitoring data will be reported using the DMS monitoring template. The monitoring report provides a project data chronology to facilitate an understanding of project status and trends, population of DMS databases for analysis, research purposes, and assist in decision making regarding project close-out.

The survivability of the vegetation plantings will be evaluated using a 100m2vegetative sampling plots randomly placed in the planted areas. Groundwater elevations will be monitored to evaluate jurisdictional wetland hydrology. Verification of wetland hydrology will be determined by automatic recording of well data collected within the project area. 4.0 MAINTENANCE AND CONTINGENCY PLAN DMS shall monitor the site and conduct a physical inspection of the site a minimum of once per year throughout the post -construction monitoring period until performance standards are met. These site inspections may identify site components and features that require routine maintenance. Routine maintenance should be expected most often in the first two years following site construction and may include the following: Year 3 Annual Monitoring Report Black Gum Creek 97063 5 Component/Feature Maintenance through project close-out Remedial Measures Vegetation shall be maintained to ensure survival. Routine vegetation Any remedial activities performed will be Vegetation maintenance and repair activities may include supplemental planting. documented in the annual monitoring reports. The site will also be evaluated to ensure diffuse flow is still occurring. Site boundaries shall be identified in the field to ensure clear distinction between the mitigation site and adjacent properties. Boundaries may Site Boundary be identified by fence, marker, bollard, post, tree -blazing, or other Any remedial activities performed will be means as allowed by site conditions and/or conservation easement. documented in the annual monitoring reports. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as needed basis. 5.0 YEAR 3 MONITORING Year 3 annual monitoring (MY3) was conducted on June 20, 2018 and January 10, 2019. As stated in Section 3.0, year 3 monitoring activities included visual monitoring and stem counts of the project vegetation; downloading monitoring gauge data; verifying the presence, or lack of, invasive species; checking the integrity of the easement; and taking photographs at the established photo points. All eight (8) vegetation plots met the vegetative success criteria with a project -wide average of 481 stems per acre (Figure 3, Appendix B and Table 7, Appendix C). Veg plot 1 was reestablished February 6, 2018 due to a fire in the late 2016-17 dormant season. The fire was low intensity and did not affect vigor of planted hardwood trees. To avoid any potential future fire issues, pvc posts for veg plots 1 and 2 were replaced with metal conduit posts, and the southeast corner (0,0) of the remaining plots (3-8) were replaced with a metal conduit post. Hydrology data indicated that two of three gauges in the rehabilitation area (gauges 1 & 5) met the hydrologic success target of greater than 8% of the growing season (Appendix D). Hydrology for gauge 4 did not meet success criteria. However, it is important to note that the location of gauge 4 exhibited signs of continuous inundation during multiple monitoring trips and has an established stand of obligate wetland grasses and rushes and several desirable species of volunteer trees. Gauge 4 was replaced February 6, 2018 due to a fire that burned through the northernmost portion of the project rehabilitation area in the late 2016-17 dormant season. Gauges 2 and 3 are both located outside of the wetland rehabilitation areas. Gauge 2, which is just outside the rehabilitation asset line, indicated that the water table was continuously above 12" for 22.7% of the growing season while gauge 3, further away from any proposed wetland rehabilitation, only had 6.6% continuous hydrology; potentially indicating that the wetland asset lines for rehabilitation were drawn appropriately. All gauges had an increase in hydrology from the prior monitoring year despite low antecedent rain conditions resulting in an extremely dry summer. This increase may be attributed to extreme weather conditions late in the season (Hurricane Florence, September 2018 and Hurricane Michael, October 2018). Future access to this site needs to be considered due to frequent inundation making it difficult to access.
