The project created low areas across an access road adjacent to the Meadowbranch Canal based on flood elevations, removed a former logging road, and planted native wetland vegetation in select areas. According to the Restoration Plan (The John R. McAdams Company, Inc., 2007) and the Baseline Monitoring Report (EcoEngineering, 2011), the intent of this project was to return the site to a more natural hydrologic state to accomplish the following objectives: • Store and treat runoff from 1.8 square miles of developed land. Nearly half the land area of Lumberton drains to the project site. • Allow for retention and treatment of sediment, nutrients, and toxins to improve water quality of the Lumber River, an impaired stream located approximately six miles downstream of the project site. • Support the goals outlined in the 2003 Lumber River Basinwide Water Quality Plan by implementing a project within a watershed that has been identified by the NC Wetlands Restoration Program (NCWRP) as having the greatest need. • Assist in the improvement of water quality; the Basinwide Water Quality Plan indicates 406 miles of waters within Subbasin 03-07-51 are impaired. • Provide a more natural flood regime and flood storage for waters in Meadowbranch Swamp. • Connect to surrounding wetland areas and enhance the wildlife habitat present in the wetland. The project site is approximately one-half mile west-northwest of Lumberton, in Robeson County, North Carolina. The site consists of a wooded parcel owned by the Lumber River Conservancy which encompasses approximately 55.4 acres (Figure 1). The site is located along Carthage Road which bounds the site to the south. Located immediately adjacent to the west of the site is a channelized water feature known as Meadowbranch Swamp Canal. There is an access road, which is maintained by the City of Lumberton, along Meadowbranch Swamp Canal which extends north from Carthage Road to NC 211. In addition, there was a former logging road located within the interior of the site which began approximately 100 feet from Meadowbranch Swamp Canal. The former logging road began at Carthage Road and extended north, roughly paralleling Meadowbranch Swamp Canal for a distance of approximately 2,000 feet. Along the eastern edge of the former logging road was a ditch feature. The site is located in the Inner Coastal Plain Physiographic Region of North Carolina and lies within US Geological Survey (USGS) Hydrologic Unit Code 03040203 080010 (NCDENR, 2003), which falls within the Lumber River Basin.The NC Division of Water Resources (NCDWR) River Subbasin for the project area is listed as the Lumber 03-07-51 (NCDENR, 2003). The current state classification (NCDENR, 2012) for Meadowbranch Swamp (Stream Index # 14-12 aka Saddletree Swamp) from its source to the Lumber River, is C; Sw (swamp waters). Class C waters support aquatic life, wildlife, and they can also be used for secondary recreation and agriculture. The Sw classification is intended for waters which have low velocities and other natural characteristics different from adjacent streams. 1 92351— Meadowbranch Swamp — MY5 Report (Version 1.4, 11/07/11) URS — January 2016 The project site is almost entirely forested primarily with young hardwoods and some areas of young pine. This is due to the fact that the site was logged approximately 15 years ago. Due to the timing of the logging, the site is currently at a stage of succession where the vegetation is very dense. Currently, there are a few small areas near the access road along Meadowbranch Swamp that still have stands of relatively older growth bald cypress (Taxodium distichum) and would be designated as Cypress -Gum Swamp (Schafale and Weakley, 1990). Other larger areas have some young bald cypress, but are more dominated by red maple (Acer rubrum) and river birch (Betula nigra). Aside from the few areas of Cypress -Gum Swamp on the site, the remainder of the area is best described as a disturbed site undergoing succession to a Coastal Plain Bottomland Hardwood forest (based on reference wetland conditions) (Schafale and Weakley, 1990). In general, the majority of the site appears to have characteristics of a Coastal Plain Bottomland Hardwood forest. However, some portions of the site contained large concentrations of Chinese privet (Ligustrum sinense) which have been removed and treated. These areas have been replanted with native vegetation. 1.1 VEGETATION Monitoring Year 5 (MY5) field investigations took place on December 1, 2016. All three vegetation plots are in good condition and all are meeting vegetative success criteria with a project average of 486 stems per acre. Large numbers of volunteer stems, primarily river birch are present in all three plots. Two randomly selected transects were inventoried within the Chinese privet removal areas. Both transects contained large numbers of Chinese privet and very few other species. Native species were all larger naturally occurring trees and no planted native stems were observed. The dominant shrub stratum in both transects was Chinese privet. There are some larger native canopy trees in the area, but native species were observed in very small numbers in the shrub and sapling stratum. The percentage of Chinese privet in the two random transects was 78 percent and 88 percent, respectively. These results are presented in Table 9 of Appendix C. The presence of Chinese privet continues to be a problem at the site, especially along the canal access road and in the cut lines leading to the groundwater gauges between the former logging road and the canal access road. Treatment areas are notable in that there are large patches of stems that appear dead; however, upon closer observation, new growth is present on some of these stems. Treatment was successful in some areas, but not all. Chinese privet is still present in very dense patches along the canal access road in the northern portions of the site. Areas identified as invasive areas of concern during previous monitoring years remain on the Current Condition Plan View. Overall, the site is in good condition, with the exception to the presence of Chinese privet. While the Chinese privet is still present, the limits do not appear to be expanding. The northern portions of the site continue to support the largest populations. 1.2 HYDROLOGY The growing season is 213 days, and has been set from April 1 to October 30. Criteria established for the site state that groundwater levels must be at or above 12 inches of the ground surface for 10 percent of the growing season, or 21 consecutive days. Nine of the 12 groundwater 2 92351— Meadowbranch Swamp — MY5 Report (Version 1.4, 11/07/11) URS — January 2016 gauges installed on-site met the hydrologic success criteria described above during the timeframe between April 1 and October 30 of 2016 (Table 11). The reference wetland gauge also met the wetland criteria. Gauge 5 appears to have malfunctioned early in the year and the readings were determined to be non -reliable. Two gauges were not able to be downloaded in the fall (Gauge 4 and 13), due to damage from flooding or from vandalism. However, data for the early part of the growing season had been obtained during the May site visit. A rain gauge was installed on the site in October of 2006. Due to persistent problems with the gauge, NC CRONOS data has been relied upon to provide reasonable estimates for site rainfall totals. To date, rainfall estimates have been provided through the NC Climate Retrieval and Observations Network of the Southeast (NC CRONOS) Lumberton station (315177), which is in close proximity (less than 0.6 miles) to the site. Normal annual precipitation for the station is 47.9 inches. Rainfall over the past 12 months totaled 65.3 inches, indicating that the past year has been above normal. On-site stream gauge data and USGS stream gauge data indicate up to four bankfull events over the past year (January 1 to November 30, 2016). A 16 day event that began on December 24 and continued until January 9, a seven day event from February 5 to February 12, a two day event beginning February 17 and a 14 day event associated with hurricane Matthew that began on October 8 and continued until October 21. During hurricane Matthew water levels on portions of the site exceeded 5 feet. 1.3 OTHER ISSUES Hurricane Matthew moved into North Carolina on October 8, 2016 and flooded large portions of the Coastal Plain. Lumberton and the project area were affected by heavy winds and rainfall. Numerous tree windfalls were observed throughout the site. Visual observations of mudlines at the site indicate that water levels on portions of the site exceeded 5 feet. Erosion was first noted behind the matting at Roadway Cuts 1 and 2 during MYL The erosion in these areas is still present, but has not changed since MY I. More recent erosion was noted along the banks of Meadowbranch Canal in the vicinity of Roadway Cuts 3 and 4 during MY2. A new area of bank erosion was noted during the annual site assessment in May of 2014. This area is located just downstream of the stream gauge and was present during MY3 monitoring. During the MY4 site assessment (May 2015) a washout area was observed along the bank of the canal between stations 25+00 and 30+00, which appears to be due to water movement over the canal access road. Bank erosion was observed behind the matting of Berm Cut 2 and Road Cut 2. None of these areas appear to have become significantly worse during 2016. Summary information/data related to the occurrence of items such as beaver or encroachment and statistics related to 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 Baseline Monitoring Report (formerly Mitigation Plan) and in the Mitigation Plan (formerly Restoration Plan) documents available on DMS's website. All raw data supporting the tables and figures in the appendices is available from DMS upon request. 3 92351— Meadowbranch Swamp — MY5 Report (Version 1.4, 11/07/11) URS — January 2016 2.0 METHODOLOGY Three vegetation plots have been established along the former logging road within the project site. These plots were established according to CVS-EEP Protocol for Recording Vegetation (Lee et al., v.4.2, 2008) and are 20 meters by five meters in size. During MYI, the corners of each plot were marked with three-foot PVC piping and flagged. The southwest corner of each plot, or plot origin, was flagged with orange and the remaining three corners were flagged with blue. Planted stems were flagged with white. Version 4.2 of the CVS-EEP Protocol for Recording Vegetation was used to inventory these plots (Level 1-2). Natural regeneration stems were recorded but not flagged. A reference photograph was taken from the origin of each plot, facing across the plot. Additionally, two random transects, 50 meters by two meters in size were established within the Chinese privet areas and inventoried for stems greater than one meter high. Stem counts included planted stems, volunteers, and invasive species (Chinese privet). Stem species and count were recorded. No stems were flagged along the transects. Ten automated groundwater gauges, a stream gauge, and a rainfall gauge were installed at the site in October 2006. These gauges were installed in order to monitor the water table at the site during the initial project investigation and design. One of the 10 gauges was placed on the west side of Meadowbranch Swamp Canal in the reference wetland area in order to monitor reference wetland hydrology. Following the completion of construction, three additional automated groundwater gauges (gauges 11 through 13) were placed within the limits of the restored area of the former logging road to measure the groundwater table. All 13 gauges were located and marked with blue and white striped flagging. All 13 gauges are Ecotone brand water level monitors whose data were downloaded using a handheld Meazura MEZ1000 data logger. For the gauges where transects were used to locate them away from the former logging road or maintenance road, pink flagging was used to mark transect lines. The stream gauge and rainfall gauge are also Ecotone brand monitors and the data gathered by those devices was downloaded using the same equipment stated above. 92351— Meadowbranch Swamp — MY5 Report (Version 1.4, 11/07/11) URS — January 2016 3.0 REFERENCES EcoEngineering. 2011.

A multi -day event that began on December 24, 2015 and continued to January 8 2016, two small events in February, and a large event in October 2016 following hurricane Matthew. Proximal USGS gauge data supports these findings. Potential bankfull occurrence from January 1 to November 30, 2016 was extrapolated based on USGS stream gauge discharge data for the Lumber River at Lumberton, NC. The USGS gauge plot is shown on Figure 3. The gauge is located less than two miles downstream from the project site and has a drainage area of 708 square miles. An estimate of the number of bankfull events between January 1, 2016 and November 30, 2016 was made by comparing the stream discharges from the USGS data in cubic feet per second (cfs) against the bankfull discharge estimated from the drainage area on the Coastal Plain Regional Curve. According to the regional curve, a bankfull event occurs on a stream with a 708 -square mile drainage area when the discharge is about 2,000 cfs. This discharge was exceeded four times during the past year: • January 1 to January 9, 2016 with a peak discharge of 5,080 cfs on 1/1/2016 • February 5 to February 12, 2016 with a peak discharge of 2740 cfs on 2/9/2016 • February 17 to February 18, 2016, with a peak discharge of 2040 cfs on 2/17/2016 • October 8 to October 21, 2016, peak discharge of 12,200 cfs on 10/11/2016 (Hurricane Matthew) Based on a comparison of the on-site data logger and the USGS gauge data it appears that a slightly more accurate estimate of bankfull for Meadowbranch Canal is when the USGS gauge on the Lumber River is at around 2500 cfs.

Ten percent of growing season is equal to 21 days or more of consecutive readings above 12 inches. ** Gauges 6 and 10 both protrude from the ground. The elevations have been adjusted to compensate for the distance between the calibration level and the ground surface. Gauge 6 is 5 inches above the ground, and gauge 10 is 6 inches above the ground. Gauges meeting wetland success criteria are highlighted in blue. Those not meeting wetland success criteria are highlighted in red. Gauge 4 in 2016 - Gauge malfunctioned during the October flood event and data following the May 20, 2016 site visit was lost. Gauge 5 in 2016 - Water levels were recorded as being 100+ feet and the gauge was determined to be not working. Gauge 13 in 2016 - Gauge was vandalized following May 20, 2016 site visit however, hydrologic criteria had been met earlier in the growing season. 36 92351- Meadowbranch Swamp - MY5 Report (Version 1.4, 11/07/11) URS - January 2016
