The project involved the enhancement of 1,850 linear feet of an unnamed tributary (UT) to Sandy Creek, 2.2 acres of wetlands and 8.8 acres of riparian buffer. The Site is protected for perpetuity under a conservation easement purchased from Mr. Charles Williams in 2006. Project restoration components, activity and reporting history, contacts and attribute data are all provided in Appendix A. 1.1 Goals and Objectives The Project’s goals were to: • reduce nutrient and sediment water quality stressors; • provide for uplift in water quality functions; • improve instream and wetland aquatic habitats, including riparian terrestrial habitats; and, • provide for greater overall instream and wetland habitat complexity and quality. Stream enhancement, the primary component, served as the dominant input for achieving this goal. No restoration goals were identified in the Cape Fear River Basinwide Management Plan (NCDWQ, 2005) with regard to the Sandy Creek watershed. There were no sources or stressors listed for the watershed area associated with the Project Site. The NC Department of Environment and Natural Resources (NCDENR) Division of Mitigation Services (DMS) develops River Basin Restoration Priorities (RBRP) to guide its restoration activities within each of the state’s 54 cataloging units. RBRPs delineate specific watersheds that exhibit both the need and opportunity for wetland, stream and riparian buffer restoration. These watersheds are called Targeted Local Watersheds (TLWs) and receive priority for DMS planning and restoration project funds. The 2009 Draft Cape Fear River RBRP identified HUC 03030003020010, which includes the Project Site, as a Targeted Local Watershed. The following information is taken directly from the RBRP. “…This is a largely rural hydrologic unit (HU). The main stream, Sandy Creek, flows through Randolph County to Sandy Creek Reservoir, a drinking water supply for Ramseur and Franklinville. As of 2006, the HU had no streams on DWQ’s list of impaired waters; however, the reservoir shows indications of high nutrient levels, likely related to the large number of animal operations in the HU. The HU is a Water Supply Watershed and a long portion of Sandy Creek is recognized by the State’s Natural Heritage Program as a Significant Natural Heritage Area. DMS has been active in the HU with five projects that include components of preserving wetlands (3 acres) and streams (5,100 linear feet) and restoring wetlands (15 acres) and streams (15,000 linear feet). Piedmont Land Conservancy has also been active in protecting streamside buffers in the HU. Continued implementation of practices to reduce nutrient inputs to Sandy Creek Reservoir is recommended for this HU.” 1.2 Background Summary The Project Site is situated in northeastern Randolph County, approximately four miles west of Liberty and six miles north of Ramseur (Figure 1). It is bordered to the north and west by undeveloped land, to the east by SR 2442 (Ramseur-Julian Road), and to the south by Sandy Creek. Northeastern Randolph Middle School is on the property opposite of Sandy Creek, to the south. The Project Site can be accessed by using the following directions from US Highway 64. Monitoring Report Year 3 (2015) Page 2 Charles Williams Stream, Wetland, and Buffer Site, Randolph County Prepared by Ecological Engineering, LLP November 2015 • Turn north on US 421 in Siler City, towards the Town of Liberty. • Proceed approximately 9.5 miles and turn south (left) onto NC 49. • Proceed approximately 0.7 miles along NC 49 and turn north (right) onto SR 2459 (Sandy Creek Church Road). • Follow Sandy Creek Church Road approximately 4.5 miles until it intersects with Ramseur- Julian Road and turn north (right), • Follow Ramseur-Julian Road approximately 0.3 miles, crossing over Sandy Creek. The Charles Williams Site is on the west (left) side of the roadway, immediately north of Sandy Creek. Situated in the Piedmont physiographic province and the Cape Fear River Basin, the Project Site encompasses 18 acres of former pasture and existing riparian forest. Elevations across the Site range between approximately 550 and 560 feet above Mean Sea Level. The following chart depicts pre- implementation existing condition information regarding the Site.

Underlying Mapped Soil(s) Chewacla loam NCDWQ Score (Perennial) Drainage Class Somewhat poorly drained Rosgen Classification C5 Hydric Status B Slope 0-2 % Available Water Capacity Moderate to High FEMA Classification Zone AE Invasive Vegetation Observed Multiflora rose (Rosa multiflora) Chinese privet (Ligustrum sinense) 1.3 Vegetation Condition and Comparison to Success Criteria Vegetation success criteria are consistent with the US Army Corps of Engineers (USACE) Wilmington Regulatory District’s guidance for stream and wetland mitigation and the NCDENR’s guidance for riparian buffer credit. The USACE guidance requires the survival of a minimum of 320 planted woody stems/acre after Monitoring Year 3 (MY3). A mortality rate of 10% is allowed after MY4 assessments (288 stems/acre) and, correspondingly, after MY5 assessments (260 stems/acre). The NCDENR guidance requires survival of at least 320 native, planted, hardwood stems/acre (trees only) at the end of the MY 5 to successfully earn riparian buffer credit. Vegetation is currently being assessed using plot layouts consistent with the Carolina Vegetation Survey (CVS) Level II Vegetation Protocol. Stem count data is ascertained from 12 permanently placed 10-meter2 vegetation plots (Figures 3a and 3b). Assessments include counts of both planted and natural stems. Due to low stem counts during MY2, supplemental planting of species in the original planting list at approximately 300 stems per acre was performed between December 2014 and March 2015. Based on the current monitoring effort, 12 of 12 vegetation plots met the minimum success criteria established for MY3 stream/wetland mitigation criteria and 12 of 12 plots met the criteria for riparian buffer credit. Appendices B and C depict more detailed information regarding the vegetation condition, including annual photograph comparisons and additional information regarding the proposed supplemental planting. Monitoring Report Year 3 (2015) Page 3 Charles Williams Stream, Wetland, and Buffer Site, Randolph County Prepared by Ecological Engineering, LLP November 2015 Due to the random placement of vegetation plots, only one of the eight plots associated with stream/wetland credit is currently placed within the wetland enhancement area (Vegetation Plot #6). The remaining seven plots are situated in non-wetland areas; however, based on current site conditions, three plots (Vegetation Plots #3, #7, and #8) may likely be in wetland areas by the time MY4 assessments are performed. The wetland status of the current plots will be reassessed during MY4 activities. 1.4 Stream Stability/Condition and Comparison to Success Criteria Enhancement (Level I) of the UT utilized natural channel design methodologies consistent with Priority Level IV stream restoration protocols. These protocols specifically include the stabilization of the existing channel in place. To document successful stabilization, a minimum of two bankfull events must be documented within the standard five-year monitoring period. In order for the hydrology-based monitoring to be considered complete, the two events must occur in separate monitoring years. A bankfull event was actively observed on April 17th, 2015 during a rainfall event. Additional evidence of this and other subsequent bankfull events was documented on June 30, 2015. Evidence consisted of wrack material and sediment staining above the bankfull indicators along the channel and alluvial deposits outside the channel. The crest gauge was checked in June 2015, but could not be successfully read due to a large aggregation of ants within the gauge. Annual photograph comparisons of the stream channel are depicted in Appendix B and hydrologic data associated with this year’s monitoring assessment are provided in Appendix E. 1.5 Wetland Condition and Performance Relative to Success Criteria Wetland enhancement work was performed throughout the existing wetland areas. Prior to enhancement, these wetlands were severely degraded as a result of continuous soil compaction and grazing from livestock. The enhancement work included livestock removal via exclusion fencing and supplemental plantings. Benefits of the enhancement include water quality improvement by trapping nutrients such as nitrogen and phosphorous, toxic substances, and disease-causing microorganisms. Wetlands also slow and intercept surface runoff, protect stream banks from erosion, protect upland areas from flooding, and provide valuable habitat for wildlife. 1.6 Other Information Summary information/data related to the occurrence of items such as beaver dams 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 the Restoration Plan) documents available on the DMS website. All raw data supporting the tables and figures in the appendices is available from DMS upon request. Boundary marking along the conservation easement using signage consistent with DMS guidelines was performed by Ecological Engineering on December 8, 2014, and is considered completed. During MY2 monitoring, a recently constructed beaver dam was observed within the channel at approximately station 14+34.75. In May of 2015 during MY3 monitoring, another recently constructed beaver dam was observed immediately upstream of the culverted road crossing at approximately station 19+51.50. During June of 2015, these dams were removed by hand and beaver trapping was Monitoring Report Year 3 (2015) Page 4 Charles Williams Stream, Wetland, and Buffer Site, Randolph County Prepared by Ecological Engineering, LLP November 2015 conducted by APHIS. As of June 30, 2015, no additional beaver activity was observed within the easement area. Please refer to Appendix B for representative photographs. Based on comments received pertaining to the stream stability monitoring, additional detail was collected during the MY3 longitudinal profile survey. Pattern and profile data was collected to represent the current state of the UT from the upstream, northern easement boundary downstream to the southern easement boundary. Please refer to Appendix D for a comparison of MY3 data with previous monitoring data. It is important to note that, because longitudinal profile survey shots were taken at different channel locations across the monitoring years, it is not possible to fully assess stream bed stability based on the current longitudinal profile comparison. Subsequent survey data in future monitoring years will be collected to the level of detail represented in MY3 data, which will allow an ongoing comparison of stream bed stability. An additional Appendix F is provided to depict the detailed longitudinal profile of the channel thalweg. For ease of comparison, this appendix consists of four sheets, each showing a reach of the channel thalweg at a larger scale than the chart in Appendix D. Monitoring Report Year 3 (2015) Page 5 Charles Williams Stream, Wetland, and Buffer Site, Randolph County Prepared by Ecological Engineering, LLP November 2015 2.0 METHODOLOGY This monitoring report follows methodology consistent with DMS’s Procedural Guidance and Content Requirements for Monitoring Reports (Version 1.4, dated 11/07/11), available at the DMS website (http://portal.ncdenr.org/web/eep). All surveys were performed via total station and survey grade Global Positioning System (GPS). Each survey point has three-dimensional coordinates and is tied to survey control points. Longitudinal profile stationing was originally developed based on the design stationing, and follows the UT from the northern to the southern property boundary (upstream to downstream) as depicted on the survey plat. Based on comments from DMS during the review of the draft MY2 monitoring report, the MY3 longitudinal profile survey incorporated more detailed data collection to more accurately represent changes in channel morphology over time. As the MY3 survey is a more complete longitudinal profile, channel stationing is more accurate than that shown in previous longitudinal profiles. In order to compensate for differences in stationing, channel survey shots from previous monitoring years were viewed in plan view and compared to MY3 channel stations. Stationing of previous years’ shots was adjusted to reflect the more accurate MY3 channel stationing. Appendix D includes an overlay of channel survey data based on this adjusted stationing. Subsequent surveys will continue to collect the level of detail represented in the MY3 survey. Particle size distribution protocols followed the Wolman Pebble Count Procedure, which requires an observer with a metric ruler to measure particles based on their intermediate axis. This information is correlated into a graph depicting a particle size analysis of the cross section. Vegetation assessments were conducted using the CVS protocol (Version 4.2). As part of this protocol, vegetation is assessed using 100-meter2 plots, or modules. The scientific method requires that measurements be as unbiased as possible, and that they be repeatable. Plots are designed to achieve both of these objectives; in particular, different people should be able to inventory the same plot and produce similar data (Lee et. al., 2006). According to Lee et. al. (2006), there are many different goals in recording vegetation, and both time and resources for collecting plot data are extremely variable. To provide appropriate flexibility in project design, the CVS protocol supports five distinct types of vegetation plot records, which are referred to as levels in recognition of the increasing level of detail and complexity across the sequence. The lower levels require less detail and fewer types of information about both vegetation and environment, and thus are generally sampled with less time and effort (Lee et. al., 2006). Level 1 (Planted Stem Inventory Plots) and Level 2 (Total Woody Stem Inventory Plots) inventories were completed on all 12 of the vegetation plots at the Project Site. A crest gauge was installed near the downstream end of the Site along the UT to verify the on-site occurrences of bankfull events. In addition to the crest gauge, observations of recently deposited overbank wrack and/or sediment serve to validate gauge observations, as necessary. Documentation of the highest stage during the monitoring interval is assessed during each site visit and the gauge is reset. The data related to bankfull verification are summarized in each year’s report. Based on the elevation of the crest gauge, any readings observed higher than 22 inches on the gauge reflect a bankfull or above bankfull event.
