The project consists of 3.13 acres of wetland restoration and 2,461 linear feet of Level II stream enhancement. The conservation easement encompasses 22.6 acres and includes an additional 7.1 acres of preserved existing wetlands. Wetland and stream construction originally took place in 2003. Wetlands restoration consisted of grading activities and planting wetland vegetation. Stream enhancement consisted of the installation of log vanes to create pool features to enhance habitat and water quality along 2,461 linear feet of stream. The wetland restoration area was again re- graded between December 2009 and February 2010 to correct final grade elevations to establish proper wetland hydrology. Topsoil was added to improve soil fertility for plant growth and the graded areas were replanted with native plant species. This monitoring report represents the 4" year of wetland monitoring after site maintenance and re- grading. Stream monitoring has been conducted annually since original restoration activities completed in 2003. 1.1 Goals and Objectives Project Goals: • Improve water quality by incorporating log vanes within the stream channel and planting the stream buffer • Improve wetland hydrology with the removal of fill material and the sludge drying beds • Improve in- stream habitat with the installation of log vanes to enhance pool depths • Restore wetland function with the incorporation of woody and herbaceous wetland plant species Project Objectives: • The Level II stream enhancement of 2,461 linear feet of Sandy Creek • Restoration of 3.13 acres of wetlands through the removal of fill material and the sludge drying beds to improve wetland hydrology • Establishment of a 22.6 acres conservation easement 1.2 Vegetative Assessment Currently the vegetation is meeting the success criterion with 677 total woody stems /acre. The success criterion for vegetation is 260 total woody stems /acre at the end of the monitoring period. Based on the CVS vegetation data there are 313 planted woody stems /acre and 677 total woody stems /acre. As a result of the wetland re- grading in December 2009, the vegetation in monitoring plots 2, 3, and 4 was removed, leaving only vegetation monitoring plot 1 intact. The site was replanted and plots 2, 3, and 4, were re- established in February 2010. Warranty planting was conducted in February 2011 to replace trees that did not survive initial replanting after the Sandy Creek Year 8 Monitoring Report NCEEP Project Number 322 Year 8 of 9 The Catena Group I October 2013 wetland was re- graded. Level Il of the CVS -EEP protocol was administered for plots 1, 2, 3, and 4, which accounts for natural and planted woody stems. Some planted stems are still exhibiting evidence of being smothered by the herbaceous vegetation (i.e. Juncus effuses, Lespedeza cuneata). Vegetation problem areas mainly consist of invasive exotic species. Chinese lespedeza ( Lespedeza cuneata), continues to thrive in patches along the adjacent forest margin and throughout the wetland in the vicinity of plots 3 and 4. These areas along the woodland margin have remained undisturbed throughout the monitoring period. 1.3 Stream Assessment In general the stream banks are well vegetated and stable. The majority of the log vanes are stable, providing bank protection as intended, and generating scour pools providing habitat. The cross section shows little change in stream dimension as compared to previous monitoring data. Some erosion was observed at station 4 +00 on the upstream portion of the log vane. The log structure and the adjacent banks are stable. Some localized bank erosion and logjams were observed near stations 23 +00 and 13 +50. Debris is located at the upstream face of the culverts at US 15 -501. Notification to NCDOT regarding the current blockage is recommended so that maintenance can be preformed. 1.4 Wetland Assessment The site was re- graded between December 2009 and February 2010. New groundwater gauges were installed in the spring of 2010 at three locations — the reference wetland gauge, gauge A, and gauge C. The reference gauge was installed in its original location and Gauge B remained undisturbed in its original location. On May 23, 2013 four addition gauges (D, E, F, &G) were installed. Gauges D, E, F were installed within the wetland restoration area to capture a more accurate depiction of the groundwater levels. Gauge G was installed within the adjacent alluvial forest along Sandy Creek as supplemental reference gauge. ]Gauges A, B, and C exhibited saturation within 12 inches of the ground surface for more than 12.5% of the growing season. Gauges D, E, F, and G did not collect data for a complete growing season however these wetland areas have exhibited evidence of wetland hydrology (Table 13). The average annual growing season for Durham County is 222 days (March 24 to November 1). 1.5 Annual Monitoring Summary Summary information /data related to the occurrence of items such as beaver or encroachment, and statistics related to performance of various projects 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 and restoration plan documents available on EEP's website. All raw data supporting the tables and figures in the appendices are available from EEP upon request. Sandy Creek NCEEP Project Number 322 The Catena Group Year 8 Monitoring Report Year 8 of 9 October 2013 2.0 METHODOLOGY All monitoring methodologies are a combination of current NCEEP templates and guidelines and previous monitoring reports (EEP template version 1.4 11/07/2011). Level II of the CVS —EEP Protocol for Recording Vegetation (Lee et al. 2008) was used for vegetation data collection. Photos were taken with a digital camera. A Trimble Geo XT handheld unit with sub -meter accuracy was used to collect monitoring feature locations and vegetation problem areas. Stream assessments followed methodologies outlined in Applied River Morphology ( Rosgen 1996). Precipitation data were obtained from the State Climate Office of North Carolina (http: / /www.nc- climate .ncsu.edu /services / request.php) (State Office of North Carolina 2013). Flora of the Carolinas, Virginia, Georgia, and Surrounding Areas was the taxonomic standard used throughout vegetation data collection (Weakley 2012). Vegetation monitoring data was collected on August 16, 2013. Stream monitoring was conducted on June 5, 2013. 3.0 REFERENCES Lee, Michael T., R. K. Peet, S. D. Roberts, and T. R. Wentworth. 2008.

In the event a polygon is cataloged into items 1, 2 or 3 in the table and is the result of encroachment, the associated acreage should be tallied in the relevant item (i.e., item 1,2 or 3) as well as a parallel tally in item 5. 4 = Invasives may occur in or out of planted areas, but still within the easement and will therefore be calculated against the overall easement acreage. Invasives of concernlinterest are listed below. The list of high concern spcies are those with the potential to directly outcompete native, young, woody stems in the short -term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established treelshrub stands over timeframes that are slightly longer (e.g. 1 -2 decades). The low /moderate concern group are those species that generally do not have this capacity over the timeframes discussed and therefore are not expected to be mapped with regularity, but can be mapped, if in the judgement of the observer their coverage, density or distribution is suppressing the viability, density, or growth of planted woody stems. Decisions as to whether remediation will be needed are based on the integration of risk factors by EEP such as species present, their coverage, distribution relative to native biomass, and the practicality of treatment. For example, evert modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control, but potentially large coverages of Microstegium in the herb layer will not likley trigger control because of the limited capacities to impact treelshrub layers within the timeframes discussed and the potential impacts of treating extensive amounts of ground cover. Those species with the "watch list" designator in gray shade are of interest as well, but have yet to be observed across the state with any frequency. Those in red italics are of particular interest given their extreme risk /threat level for mapping as points where isolated specimens are found, particularly ealry in a projects monitoring history. However, areas of discreet, dense patches will of course be mapped as polygons. The symbology scheme below was one that was found to be helpful for symbolzing invasives polygons, particulalry for situations where the conditon for an area is somewhere between isolated specimens and dense, discreet patches. In any case, the point or polygonlarea feature can be symbolized to describe things like high or low concern and species can be listed as a map inset, in legend items if the number of species are limited or in the narrative section of the executive summary. % of Mapping CCPV Number of Combined Easement Ve2etation Cate2ory Definitions Threshold De irtion Pal ons ea a Acrea e 4.
