It includes portions of two unnamed tributaries (UTs) to Altamahaw Creek. The enhancement lengths of the main and secondary channels are 1,347 and 130 linear feet, respectively. In addition, 0.026 acres of wetlands were enhanced as part of the overall project. The UT Altamahaw Site is protected for perpetuity under a conservation easement purchased from Mr. Charles Hursey Sr., Charles Hursey II, Christopher Hursey and Carey Hursey in 2008. 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 project component, served as the dominant input for achieving these goals. These goals were consistent with the Travis and Tickle Creek Local Watershed Plan (LWP). The LWP, completed in 2008, identified six goals; two of which are met by the Project. These are (1) to improve water quality through stormwater management and (2) to identify and rank parcels for retrofits, stream repair, preservation and/or conservation. The Project improved the existing emergency spillway associated with a large pond immediately upstream of the Project Site. Prior to improvement (stabilization), this spillway was severely eroded and contributed sediment into the main stream channel. The existing stream crossing was also stabilized to further prevent erosion into the main stream channel. The Project also included the design and installation of a modified level spreader to diffuse surface flows from the nearby pasture through a vegetated buffer. In addition, the Site was also one of the specific areas identified through the stakeholder process associated with the LWP. The LWP process identified nine key watershed stressors and their corresponding management strategies. These stressors were identified via local stakeholder groups including DMS, Piedmont Land Conservancy, Haw River Assembly, Piedmont Triad Council of Governments, Alamance and Guilford Counties, Natural Resources Conservation Service, Cities of Burlington and Graham, Towns of Elon and Gibsonville, NC Division of Water Resources, NC Wildlife Resources Commission and Resource Conservation & Development. The UT to Altamahaw Stream Enhancement Project combats six of those stressors with the following strategies: Kev Watershed Stressors Stream bank erosion Lack of adequate buffer Stormwater runoff Livestock access to streams Nutrients Fecal coliform Manaaement Strateaies Riparian buffers & livestock exclusion Riparian buffers & livestock exclusion Stormwater BMPs Livestock exclusion Agricultural BMPs, riparian buffers & stormwater BMPs Agricultural BMPs & stormwater BMPs Monitoring Report Year 5 (2016) Page 1 UT Altamahaw Site, Alamance County Prepared by Ecological Engineering, LLP October 2016 The objectives were to completely exclude livestock from the easement area and to install plantings designed to maintain vertical stability, lateral stability and habitat, as well as re -vegetate and supplement those areas lacking suitable vegetation along the easement area. An alternative livestock water supply was provided and the existing crossing was improved to prevent further erosion. In addition, enhancement of the auxiliary spillway associated with the pond immediately upstream of the Site and construction of a modified level spreader to combat surface flows from the pasture were also completed as part of implementation activities. Ultimately, this supplemental planting will provide increased opportunities for the filtration of pollutants and nutrients prior to entering the stream channel, as well as the stabilization of sediment along the associated stream banks. 1.2 Vegetation Condition and Comparison to Success Criteria Vegetation success criteria at the Site are consistent with the USACE Wilmington Regulatory District's guidance for wetland mitigation which documents the survival of a minimum of 320 planted woody stems/acre after Monitoring Year 3 (MY3). The mortality rate of 10% is allowed after MY4 assessments (288 stems/acre) and correspondingly, MY5 assessments (260 stems/are). Invasive, exotic species were present prior to implementation and criteria also include the removal of all such species prior to project closeout. DMS is treating invasive species. Privet and multiflora rose were treated on 10/24/2013, 5/21/2014, and 6/8/2015. Vegetation is currently being assessed using plot layouts consistent with the DMS/Carolina Vegetation Survey (CVS) Level II Vegetation Protocol. Stem count data is ascertained from five permanently placed 10-meter2 vegetation plots (Figure 2). Assessments include counts of both planted and natural stems. Based on this year's monitoring effort, four of the five vegetation plots met the minimum success criteria. Stem counts ranged from approximately 202 to 647 planted stems per acre and approximately 728 to 1,416 total stems per acre across the Site. Prior to baseline assessments and as previously reported, it was discovered that cattle had accessed the easement area between the completion of implementation activities and baseline assessments, damaging planted stems. Supplemental planting was performed in November 2013. Appendices B and C depict more detailed information regarding the vegetation condition, including annual comparative photographs. 1.3 Stream Stability/Condition and Comparison to Success Criteria No in -channel enhancement activities were conducted as part of this project. Annual assessments include comparative photographs and monitoring of channel hydrology. 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. During the previous year's monitoring (MY2, MY3 & MY4), at least one bankfull event was documented in each year. A bankfull event was not documented during the 2016 monitoring period. Annual comparative photographs of the stream channels are depicted in Appendix B and hydrologic data associated with this year's monitoring assessment are provided in Appendix D. Monitoring Report Year 5 (2016) Page 2 LIT Altamahaw Site, Alamance County Prepared by Ecological Engineering, LLP October 2016 1.4 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 DMS's website. All raw data supporting the tables and figures in the appendices is available from DMS upon request. Two of the issues from MY4 were still present in during the MY5 period. These issues included (1) surface erosion along the existing cattle crossing and (2) erosion along the auxiliary spillway immediately outside the Project Site. The surface erosion at the cattle crossing is continuing and is a result of repeated livestock trampling and compaction. This has ultimately resulted in surface waters bypassing the existing modified level spreader and erosion around the pipe along the downstream side of the crossing. The lower portion of the auxiliary spillway immediately adjacent to the easement area was repaired in late August 2015 by Backwater Environmental. Rock sills were installed and rip rap was placed between the sills. The large rip rap had moved down the slope and was partially in the unnamed tributary during the February 2016 site visit. The displaced rip rap does not appear to have migrated further into the channel as of September 2016. The rock sills are stable but the geotextile fabric is showing. The other two issues noted during the MY4 period were not present during the MY5 site visit; mowing along the fence line within the easement and a beaver dam off-site was causing a backwater effect onto the project. There was not recent evidence of mowing along the fence line. The herbaceous vegetation along the fence line was thinner due to past mowing. The apparent purpose of the past mowing was to remove and control vegetation along the existing fence lines. Past mowing extended inward approximately four to five feet from the woven wire. As documented in the attached Letter of Intent and Conservation Easement Agreement (Appendix E), mowing is allowed. There is no longer a beaver dam downstream of the project easement. The backwater effect from the dam has dissipated. METHODOLOGY This monitoring report follows methodology consistent with DMS's Procedural Guidance and Content Requirements for DMS Monitoring Reports (Version 1.3, dated 1/15/10), available at DMS's website (http://portal.ncdenr.org/web/eep). Vegetation assessments were conducted using the CVS -DMS 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 Monitoring Report Year 5 (2016) Page 3 UT Altamahaw Site, Alamance County Prepared by Ecological Engineering, LLP October 2016 project design, the CVS -DMS 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 five of the vegetation plots at the Project Site. Level 1 plots are applicable only for restoration areas with planted woody stems. The primary purpose is to determine the pattern of installation of plant material with respect to species, spacing, and density, and to monitor the survival and growth of those installed plants. Level 1 plots are one module in size (Lee et. al., 2006). Level 2 plots also are designed specifically for restoration areas and represent a superset of information collected for Level 1 plots. In these plots planted woody stems are recorded exactly as for Level 1, but in addition all woody stems resulting from natural regeneration are recorded by size class using separate datasheets. These plots allow an accurate and rapid assessment of the overall trajectory of woody -plant restoration and regeneration on a site. Level 2 plots are one module in size (Lee et. al., 2006). A crest gage was installed near the downstream end of the Site along the main UT. This gage will verify the on-site occurrences of bankfull events. In addition to the crest gage, observations of wrack and deposition will also serve to validate gage observations, as necessary. Documentation of the highest stage during the monitoring interval will be assessed during each Site visit and the gage will be reset. The data related to bankfull verification will be summarized in each year's report. Based on the elevation of the crest gage, any readings observed higher than 12 inches on the gage will reflect a bankfull or above bankfull event.

Please return this form in the enclosed envelope I have reviewed the letter of intent and conservation easement document. fs I am in agreement with the letter of intent; temporary construction easement and conservation easement template for future access in reference to the above mentioned property. ~" I have reviewed the letter of intent and conservation easement and have the following concerns: Date;,3-1�1 /�— ; Signed:— Date: Letter of intent Proposed EEP Stream Restoration Project This document sets forth agreements between the N.C. Ecosystem Enhancement Program (EEP) and the landowner regarding the proposed EEP restoration project described below. EEP is proposing a stream enhancement project on an unnamed tributary to Altamahaw Creek located on a farm owned by Charles Hursey in Alamance County. EEP is hereby providing a letter of intent regarding proposed responsibilities of EEP as they relate to the "UT to Altamahaw" enhancement project. PROJECT NAME: UT to Altamahaw EEP # 92837 EEP intends to enhance, or preserve stream and wetland areas on this site. As part of these efforts, EEP intends pay for the installation and design of agricultural BMPs (best management practices) necessary to protect the streams. BMPs will include exclusionary cattle fencing, one alternative water supply well and one watering station and two gates. Exclusionary fencing will be installed along, and approximately 1 -foot outside of, the easement boundary as it generally occurs on the tributary which occurs in the current pasture area. A 5 -foot grassy clearance zone inside the exclusionary fencing and on the conservation easement will be allowed to be managed by mowing, or other manual means, to keep this area open and clear of woody vegetation. EEP will provide grading and stone for the existing emergency spillway of the farm pond. EEP will provide stone cover for the existing culvert crossing. NOTE: Donations of land or conservation easements may be tax deductible, however, please be aware that any amenities, such as fencing or bridges, built on your land may have property tax implications. Please check with your tax attorney regarding the effects of any improvements. The completion of this project and the items described in this letter are subject to budget and timing constraints. Funding is available only for land that is protected by the restrictions described in the attached permanent conservation easement agreement.
