Executive Summary The Morgan Creek Floodplain Site (Site) is located on the Mason Farm Biological Reserve (MFBR) and is owned by the University of North Carolina at Chapel Hill. It was constructed for the North Carolina Ecosystem Enhancement Program (EEP). The design was done by Ward Consulting Engineers, P.C. and constructed by Riverworks, Inc. The fourth year monitoring was done in September 2014 by Mogensen Mitigation, Inc. (MMI). Monitoring was done in conformance with the NCEEP Monitoring Report Template_ Version 1.5—adopted 8 June 2012 and monitoring requirements issued by the NCIRT in November 7, 2011 and can be found at http: // portal .ncdenr.org /c /document library/get file?p I id= 1169848 &f6lderld = 2288101 &nam e= DLFE- 39234.pdf. The Site is located on the MFBR immediately adjacent to A. E. Finley Golf Course and down the road from the North Carolina Botanical Garden. The Site is in the Morgan Creek Local Watershed planning area and is in the Cape Fear River (Haw) 14 -digit HUC 03030002060080. The Site has been used for biological research for UNC — Chapel Hill. Restoration actions included the construction of berm openings to increase flood water access to the floodplain behind the artificial berm along Morgan Creek. The project involved 14.37 acres of wetlands, the preservation of 5.61 acres of wetlands and preservation of 3200 linear feet of riparian buffer along the south bank of Morgan Creek. The Catena Group delineated the wetland preservation area in 2005 and the reference wetland in February 2008, neither of which were verified by the U.S. Army Corps of Engineers. PROJECT GOALS & OBJECTIVES: Goals 1. Facilitate regular flooding of the Morgan Creek floodplain behind the berm; 2. Promote attenuation of sediment and nutrients on the flood plain; 3. Reduce downstream flooding by creating additional storm water detention; 4. Reduce erosion by limiting flooding shear stress on Morgan Creek banks ; 5. Restore more natural hydrology to 14.37 acres of impacted wetlands; 6. Preserve 5.61 acres of existing forested wetlands; 7. Re- establish a natural plant community through plantings and invasive species control; 8. Preserve 3200 linear feet of riparian buffer on the south bank of Morgan Creek. Objectives 1. Create five (5) stable openings in the existing artificial berm to allow flood waters to access the conservation easement area; 2. Successfully plant 14.37 acres of bottomland hardwood wetlands with native desirable trees and shrubs; 3. Demonstrate jurisdictional hydrology in 14.37 restored wetland acres by measuring groundwater through RDS continuous read monitoring gauges; 4. Preserve the entire Site through means of a conservation easement or deed restrictions in perpetuity. Five vegetation plots were located, flagged and monitored using Version 4.2 of the CVS -EEP Level 2 Vegetation Monitoring Protocol. The success criterion specified in the mitigation plan Mogensen Mitigation, Inc. 1 Morgan Creek Floodplain MY -04 Monitoring Report November 2014 requires a minimum survival rate of 288 stems per acre for MY 4. During MY 5 the success criterion drops to 260 stems /per acre. All vegetation data was collected in September 2014. Based on the overall vegetation count data for MY 4 there is a mean density of 194 planted stems /acre surviving. The mean density of surviving planted stems and naturally occurring stems combined is 777 stems /acre. All five vegetation plots fell short of meeting the 288 stems /per acre target this year, with three of them failing by greater than 10%. The overall low density of surviving planted trees is supplemented with a good survival of desirable native volunteer species except for Plot 5 which is overgrown with Japanese stiltgrass ( Microstegium vimineum) and Johnson grass. All plots exhibited natural regeneration of woody species, with stem densities of natural stems ranging from 283 to 1295 stems /acre. Native species observed in plots include green ash (Fraxinus pennsylvanica), red elm (ulmus rubra), sweetgum (Liquidambar styraciflua), silky dogwood (cornus amomum), and persimmon (Diospyrus virginiana). It is important to note that given prolific regeneration of volunteer native species resulting in an overall stem density of 777 stems /acre, NCEEP does not anticipate supplemental planting of this site. Data collected for all the plots are included in Appendix C. Problem vegetation areas were observed and photographed. These areas were dominated by microstegium, Japanese honesuckle (Lonicera japonica) and the invasive shrub buckthorn (Rhamnus davurica). Other invasive species observed included kudzu (Pueraria Montana), Chinese privet (Ligustrum sinense), Chinese lespedeza (Lespedeza sp.), multiflora rose (Rosa multiflora) and porcelain berry (Ampelopsis brevipedunculata). The NCEEP is actively treating Kudzu and porcelain berry on this site through an invasive species management contract. Japanese stilt grass is ubiquitous throughout the site and is problematic but would be very difficult to treat. The areas of problematic invasive species are noted as `VPAF on Figure 2. Vegetation Plot 5 is dominated by microstegium and is noted as `VPA2'. The low survival rates of planted stems in Plots 2, 3, 4 & 5 are noted on Figure 2, notwithstanding the prolific regeneration of natural stems in some of these areas, as noted in the text above. Significant Flood Events MMI began monitoring the Morgan Creek Floodplain in the late summer of 2013. Several significant flood events have taken place since the data collection began this fall. Previous year's monitoring reports note that there have been multiple storm events which have successfully flooded the conservation easement area through the berm openings. MY 2 report prepared by Ward Engineering, PC indicated that flood events that reach 7.8 feet above normal water surface elevation allows water to access the flood plain through the berm openings. MMI has accessed the USGS Stream Gauge #02097517 and according to this data flood stage reached 8 feet above normal water surface once (two consecutive days) in 2013 although none of those events occurred during the MMI monitoring time frame. Data from this Gauge for 2014 are reported in Appendix E. Each significant flood event that occurred in 2014 Mogensen Mitigation, Inc. 2 Morgan Creek Floodplain MY -04 Monitoring Report November 2014 was registered on the 5 crest stage gauges located at the berm openings. These occurrences are included in Table 9, below. MMI has installed manual crest stage gauges (CSG) at each berm opening and have checked these after each significant flood event. Each significant storm event crest elevation is noted using the CSGs and comparing it to the USGS stream gauge and precipitation data. The average flood height measured on the five (5) crest stage gauges was 30 inches during the fall monitoring. Due to the constriction through the berm gap openings we have incorporated a correction factor of negative 6 inches. Therefore, we have used a flood height water surface elevation of 24 inches above the existing ground elevation through each berm gap opening during any flood event that accessed the flood plain. The predicted flow pattern for a typical flood event is extrapolated across the gently sloping flood plain and is shown on Figure 3. The 24" water height flowing through each berm gap opening was assumed to become gradually shallower across the floodplain due to loss of head. This elevation would range from 2 feet at the berm openings then down to the receiving ditch that is at the back of the floodplain. Due to the shape of the floodplain and the associated existing berm it is assumed that the 24" water depth is maintained for a larger area at the downstream most portion of the project, as shown on Figure 3. Wetland Hydrology Nine RDS Groundwater gauges were installed according to the Technical Note HY- IA-3.1 (USACE 1993). The gauges record data every 24 hours and are downloaded quarterly. Seven gauges are located within or immediately adjacent to the conservation easement area and one is a reference gauge located off site. Gauge #8 was located approximately 1400 ft due south from gauge #1 in an area referred to as the "Big Oak Woods" area. It was located quite a distance from the conservation easement and therefore was abandoned according to Perry Sugg (NCEEP Project Manager). The location is shown on "Figure 4 - Restoration Site Hydrologic Features and Gauge locations" from the mitigation plan prepared by Becky Ward & Associates. Five gauges (1, 2, 4, 5 and 6) are in Wetland Restoration Soil Unit 1 where groundwater is expected to be within 12" of the surface for at least 12.5% of the growing season (27 consecutive days). Two gauges (3 and 9) are located in Wetland Restoration Soil Unit 2 where the groundwater is expected to be within 12" of the surface for at least 5% of the growing season (11 consecutive days). According to the NRCS -USDA the growing season runs from March 27 to November 3 which is 221 days (0.125 x 221 = 27 days & 221 x 0.05 = 11 days). Gauge #7 was originally installed in the reference wetland but was moved to a new location due to beaver activity and was referred to as #10 in the MY3 report. This gauge ( #10) was submerged in spring 2014, however it was subsequently located in the fall in a damaged condition and has been returned to Mogensen Mitigation, Inc. 3 Morgan Creek Floodplain MY -04 Monitoring Report November 2014 EEP for a replacement. Therefore, no data was available for this reference gauge for this MY 4 Report. NCEEP has replaced gauge #10 which will provide data for the MY5 monitoring report. In an effort to further delineate the hydrology in Wetland Restoration Area Soil Unit2, NCEEP installed three additional groundwater gauges (wells a -c) in October 2014. The locations of these new wells have been added to the appropriate MY4 visual assessment figures, however data from these new wells are not included in the MY4 monitoring report. NCEEP will be responsible for downloading data from these three new wells and providing it to MMI for incorporation into the MY5 annual report.Precipitation data was not collected from the onsite rain bucket gauge due to a malfunctioning bucket, which was removed at NCEEPs direction in 2013. Therefore onsite rainfall data from this rain gage was not available for the year. We have supplemented the site data with data from the NC Climate Office (Station name: Chapel Hill — Williams Airport. A USGS stream gauge located 1500 feet upstream of the Site (Station ID 0209517) was used to correlate precipitation data and with groundwater gauge data and is shown in the Groundwater Gauge Charts in Appendix E. The data from the RDS gauges indicates nearly all gauges have achieved jurisdictional hydrologic success criteria. The exception is Gauge # 3, which recorded groundwater depths within 12 inches of the surface for only 3% of the growing season. All other gauges achieved jurisdictional hydrology for more the 12.5% of the growing season with gauge #'s 1, 5 & 6 exceeding 20 %. Visually comparing these data to previous years' monitoring reports shows a clear trend toward reaching jurisdictional hydrology in all the wetland areas being monitored. Problem Areas The following is a summary of other problem areas (other than vegetation survival and invasive species) such as beaver encroachment, status of berm openings and anthropomorphic impacts. No beaver activity was observed during the numerous site visits made this fall. There is evidence of passive recreation by pedestrians but this is limited to walking on the mowed paths so no problems exist at this time. Several berm openings have erosion problems especially Berm Opening #1 (see photo) which has a significant pool that has eroded out. The erosion at Berm Gap #1 is getting noticeably worse and ha completely washed out the adjacent hiking trail (see picture). This should be repaired as well as the other berm openings that are experiencing erosion issues (Berm Opening's #2 & #3). Berm Opening's #4 & #5 are in reasonably good condition. Photos of all Berm openings can be found in the Site Photo's in Appendix B. NCEEP is scheduled to perform maintenance repairs on Berm Openings #'s 1 -4 during MY5. Mogensen Mitigation, Inc. 4 Morgan Creek Floodplain MY -04 Monitoring Report November 2014 II. Methodology All photos were taken with a Nikon digital camera and are available electronically. A Trimble Hand Held GPS unit was used to locate veg. plot corners, groundwater gauges and problem areas. An RDS data collector was used to download the groundwater data from all gauges to an Excel sheet format. All graphics have been done using ArcGIS and are available electronically. A. Vegetation Methodologies Five 10 x 10 square meter vegetation plots were monitored according to the CVS -EEP Level 2 Vegetation Monitoring Protocol for Recording Vegetation 4.2 (Lee et al 2008). The plot corners are marked with 1" PVC pipe and marked with bright red flagging tape. All plots were relatively easily located except for Plot #5 which was dominated by Japanese stilt grass, Johnson grass and lacked any surviving planted trees. Data collected from each plot is included in Appendix C. Monitoring plot locations are shown on the maps in Appendix A. Plant identification was aided by the seminal publication Flora of the Carolinas, Virginia, Georgia and Surrounding Areas (Schaffle & Weakly). B. Wetland Methodologies Originally, nine (9) RDS GW Monitoring Gauges were installed. Gauge #8 is no longer being monitored and Gauge #7 (previously labelled #10) was submerged and lost in the spring site visit but recovered for this fall MY 4 Report. All gauges are downloaded quarterly throughout the growing season to ensure that the gauges are functioning properly. Hence, gauges 1, 2, 3, 4, 5, 6, 7 & 9 provided data for MY4 and will be monitored in future years. Data is provided in an Excel spreadsheet and supplemented with data from the State Climate Office. All raw data supporting the tables, figures and graphs in the appendices are available to NCEEP upon request.

Invasives of concern /interest 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 tree /shrub 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, even 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 tree /shrub 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 polygon /area 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.
