(AXE) is pleased to provide you with two hard copies and a CD of digital files for the Final Little Lick Creek Annual Monitoring Report. We received your comments via email on October 25, 2018 and have addressed them as follows: The digital data and drawings have been reviewed and DMS had the following comments: a. NutrientOffsetCreditArea shapefile — When reviewing the attribute table, there did not appear to be an area depicted for FIDS 0, 1, 4 and 5, only a line when I clicked on each item. However, the attribute table does show an area. Please explain or correct. Upon review, it appeared that one of the shape ues (Drip Yoy.shp — `Axistingmature Vegetation') had not been clipped properly to the final easement boundary. This resulted in several small, linear areas where Nutrient Offset credit and Riparian Buffer credit was being calculated where it shouldn't have been. The shapefiles have been corrected This change resulted in a reduction of 0.01 acre (359 square feet) ofRiparian Buffer credit area and 0.01 acre (548 square feet) of Nutrient Offset credit area. The Project Components and Mitigation Tables in the document were also updated to reflect the change in credit areas. Footnotes were added to the table in Section 1.0 of the report and Table 1 in Appendix A that read the following: "During the Year 5 (2018) annual monitoring report review, an error in GIS credit area calculation was discovered which resulted in a slight reduction of credit area (-359 ftz of Riparian Buffer credit and -548 ft' of Nutrient Offset credit). The areas listed in this table have been revised to reflect the existing project assets. " b. Photo Point data source is using the wrong geographic coordinate system (GCS —NAD _ 1983_ 2011). Please revise to use NAD 1983 State Plane North Carolina (US Feet) per the digital drawing requirements. The geographic coordinate system was changed to NAD 1983 State Plane North Carolina (US Feet). 2. During the October 16, 2018 site visit, DMS staff was able to locate 13 comers on the property boundary. Some had green fence posts, others had rebar or other types of marking including aluminum caps. DMS will install additional posts and signage to better mark the property boundary. The sentence regarding easement markings in the first paragraph of Section 1.0 was revised as follows: "The easement boundary is currently marked with a combination of green fence posts, rebar, and aluminum caps; however NCDMS is currently in the process of installing additional posts and signage to better mark the boundary.

Kenan Jernigan Project Scientist Attachments: 2 hardcopies Final Little Lick Creek Annual Monitoring Report 1 CD containing digital support files 1.0 PROJECT SUMMARY The North Carolina Department of Environmental Quality -Division of Mitigation Services (NCDMS, formerly NCEEP) has established the Little Lick Creek Buffer Project (Project) located approximately five miles east of Durham in Durham County, North Carolina. The Project is located within the Upper Neuse River Basin Hydrologic Unit and Targeted Local Watershed 03020201050020. This document details riparian buffer and nutrient offset buffer mitigation activities within an approximately 12.14 -acre easement. The easement boundary is currently marked with a combination of green fence posts, rebar, and aluminum caps; however NCDMS is currently in the process of installing additional posts and signage to better mark the boundary. Completed project activities, reporting history, completion dates, project contacts, and project attributes are summarized in Tables 1-4 (Appendix A). This report (compiled based on the NC Division of Mitigation Services (NCDMS) Procedural Guidance and Content Requirements for DMS Monitoring Reports Version 1.5 dated 6/8/12) summarizes data for Year 5 (2018) monitoring. The Little Lick Creek Buffer Restoration Project is located in the Little Lick Creek Local Watershed planning area, which is nested in the 700 -square mile Falls Lake watershed. The Project watershed is located within 14 -digit Hydrologic Unit Code (HUC) 03020201050020, which was identified as a Targeted Local Watershed (TLW) in the North Carolina Division of Mitigation Services (NCDMS) 2010 Neuse River Basin Restoration Priority (RBRP) plan and is identified in the 2009 Little Lick Creek Local Watershed Plan (LWP) Upper Neuse Project Atlas (Butler Road). NCDMS developed a LWP for the 21 -square mile Little Lick Creek watershed area that included land use analysis, water quality monitoring, and stakeholder input to identify problems with water quality, habitat, and hydrology. The Little Lick Creek watershed is relatively undeveloped and in an active state of rural to suburban transition with agriculture, forestry, rural, and undeveloped land comprising over 50 percent of the land uses. Durham laws zone this land for intensive development; therefore, this land is rapidly being converted to residential and commercial properties. Little Lick Creek is on the NC Section 303(d) list of impaired water bodies due to poor aquatic life ratings and low levels of dissolved oxygen as the result of trash dumping, poor maintenance of on-site wastewater treatment systems, small vehicle maintenance and repair operations, outdoor materials storage, grease storage, and wash water disposal. The Little Lick Creek LWP project atlas includes this Project (Butler Road) with identified stressors resulting from anthropogenic activities related to the conversion of 80 percent of the watershed to disturbed land use/land cover with impervious surfaces covering over 14 percent of the watershed. Water quality is influenced due to the watershed slope (6 percent), the presence of moderately erodible soils, and its location within the Triassic Basin ecoregion. This project was identified for riparian buffer and nutrient offset restoration opportunities to improve hydrology, water quality, and habitat. The goals of the Little Lick Creek Project (Butler Road) address stressors identified in the Project watershed and include the following. • Restore riparian buffers associated with Little Lick Creek, a UT to Little Lick Creek, and water conveyances flowing to jurisdictional waters on site. The project goals will be addressed by the following objectives. • Reestablish natural vegetation along stream banks and water by planting existing cleared/disturbed land and treating invasive species. Project restoration activities were completed between November 2013 and December 2013 with invasive species controls ongoing. Activities included 1) removal and treatment of invasive species including rose (Rosa sp.), Japanese honeysuckle (Lonicera japonica), and Chinese privet (Ligustrum sinense); 2) mowing and/or clearing of dense areas of loblolly pine (Pinus taeda) seedlings and blackberry (Rubus argutus); 3) soil amendments based on recommendations from soil samples analyzed by the NCDA&CS Agronomy Division; and 4) plant community restoration. The implemented mitigation is as follows.

During the Year 5 (2018) annual monitoring report review, an error in GIS credit area calculation was discovered which resulted in a slight reduction of credit area (-359 ft2 of Riparian Buffer credit and -548 ft2 of Nutrient Offset credit). The areas listed in this table have been revised to reflect the existing project assets. Vegetation Success Criteria An average density of 320 planted hardwood stems per acre must be surviving after five monitoring years in accordance with North Carolina Division of Water Resources Administrative Code 15A NCAC 02B.0242 (Neuse River Basin, Mitigation Program for Protection and Maintenance of Existing Riparian Buffers) (NCDWR 2007). 2.0 METHODOLOGY Annual monitoring data will be reported using the NCDMS monitoring template. The monitoring report shall provide a chronology of project data that will facilitate an understanding of project status and trends, population of NCDMS databases for analysis, research purposes, and to assist in decision making regarding project close-out. The following table outlines monitoring requirements for this Project. Monitoring Schedule/Requirements Table Parameter Quantity Fre uenc Notes 8 CVS plots (see Figure 3 in Annually in Vegetation will be monitored using the Vegetation Appendix B for approximate Monitoring Years Carolina Vegetation Survey (CVS) locations 1-5 protocols Exotic and nuisance Semi-annual Locations of exotic and nuisance vegetation vegetation will be mapped Locations of fence damage, vegetation Project boundary Semi-annual damage, boundary encroachments, etc. will be mapped Vegetation Monitoring After planting was completed, an initial evaluation was performed to verify planting methods were successful and to determine initial species composition and density. Eight sample vegetation plots (10 - meter by 10 -meter) were installed and measured within the Site as per guidelines established in CVS -DMS Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008) (Figure 3, Appendix B). Vegetation plots are permanently monumented with 6 -foot metal T -posts at each corner, and a ten foot tall pvc at the origin. In each sample plot, vegetation parameters to be monitored include species composition and species density. Visual observations of the percent cover of shrub and herbaceous species will be documented by photograph. Vegetation plot information for MY5 (2018) was collected in October 2018 and can be found in Appendix C. Stem count measurements for MY5 (2018) indicate an average of 338 planted stems per acre (excluding livestakes) across the Project. Five out of eight vegetation plots met success criteria for MY5 (2018) monitoring based on planted stems. Plots 2 and 3 were both 3 stems shy of meeting success Little Lick Creek Restoration Project Monitoring Year 5 of 5 (2018) DMS Project No. 92542 October 2018 Durham County, NC page 2 criteria based on planted stems alone, and plot 7 was just one stem shy; however, when including natural recruits of green ash (Fraxinus pennsylvanica) and willow oak (Quercus phellos) in Plot 2, winged elm (Ulmus alata) in Plot 3, and green ash (Fraxinus pennsylvanica) and red maple (Acer rubrum) in plot 7, these plots were well above success criteria. Planted stem mortality can be attributed to competition from the dense shrub layer consisting of large quantities of naturally recruited woody stems. Several dense patches of Japanese honeysuckle (Lonicera japonica) were observed throughout the Project during years 2 (2015) and 3 (2016). The vines were negatively affecting woody stems for several years before it appeared that the woody vegetation had out - competed it during years 4 (2017) and 5 (2018). The areas previously affected by Japanese honeysuckle appeared to have recovered well during year 5 (2018) monitoring. Additionally, a small patch of Chinese lespedeza (Lespedeza cuneata) was observed in the vicinity of Plot 3 during previous monitoring years, which had contributed to low planted stem counts in this plot. A few specimens were observed during year 5 (2018) monitoring, however the population has greatly reduced in size since originally observed; therefore, it is no longer considered an area of concern. Furthermore, two patches of dense blackberry were observed during previous monitoring years; one in the northeast portion of the site, near plot 1 and one on the eastern portion of the site along the sewer easement. During year 5 (2018), it appeared that the woody vegetation was out -competing the blackberry, and the blackberry was no longer posing a threat to Site success in these areas. Lastly, a small area of easement encroachment was observed in and around CVS plot 8 during previous monitoring years. An approximately 5 meter wide strip was mowed from Butler Road to the existing maintained sewer easement. It appears no further mowing has occurred in this area since reported during year 4 (2017), and the vegetation has recovered well.

This number is calculated as the easement acreage minus any existing mature tree stands that were not subject to supplemental planting of the understory, the channel acreage, crossings or any other elements not directly planted as part of the project effort. 2 = The acreage within the easement boundaries. 3 = Encroachment may occur within or outside of planted areas and will therefore be calculated against the overall easement acreage. 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 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 DMS 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 Iikley 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. %of Mapping Number of Combined Vegetation Category Definitions CCPV Depiction Easement Threshold Polygons Acreage Acreage 4.
