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 this goal. 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) identify and rank parcels for retrofits, stream repair, preservation and /or conservation. The Project improved the emergency spillway associated with the existing pond immediately upstream of the Project Site and the existing stream crossing to further prevent erosion into the main stream channel. It 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 the local stakeholder groups including EEP, 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 Quality, 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 Management Strategies Riparian buffers & livestock exclusion Riparian buffers & livestock exclusion Stormwater BMPs Livestock exclusion Agricultural BMPs, riparian buffers & stormwater BMPs Agricultural BMPs & stormwater BMPs The objectives were to exclude livestock in their entirety from the easement area and install plantings designed to maintain vertical stability, lateral stability and habitat, as well as re- vegetate and supplement Draft Monitoring Report Year 1 (2012) UT Altamahaw Site, Alamance County Prepared by Ecological Engineering, LLP Page 1 December, 2012 those areas lacking suitable vegetation along the easement area An alternative 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 is 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% will be allowed after MY4 assessments (288 stems /acre) and correspondingly, MY5 assessments (260 stems /acre) Invasive, exotic species were present prior to implementation and criteria will also include the removal of all such species prior to project closeout Vegetation Is currently being assessed using plot layouts consistent with the EEP /Carolina Vegetation Survey (CVS) Level II Vegetation Protocol Stem count data is ascertained from five permanently placed 10- meter 2 vegetation plots (Figure 2) Assessments included counts of both planted and natural stems Based on this year's monitoring effort, only one of the five vegetation plots met the minimum success criteria Stem counts ranged from approximately 100 to 350 planted stems per acre and approximately 350 to 1,350 total stems per acre across the site Prior to baseline assessments, It was discovered that cattle had accessed the easement area between the completion of implementation activities and baseline assessments Damages were unrealized at the time, however, based on recent vegetation counts, it appears that overall seedling mortality can be attributed to this occurrence in addition to common mortality rationales such as drought, Inferior specimens, etc Appendices B and C depict more detailed information regarding the vegetation condition, including annual photograph comparisons 1.3 Stream Stability /Condition and Comparison to Success Criteria No in- channel enhancement activities were conducted as part of this project Assessments include only annual photograph comparisons and monitoring of hydrology associated with the channel 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 November 2011, at least one bankfull event occurred This was prior to installation of the crest gage though construction was complete No bankfull events were reported during 2012 Annual photograph comparisons of the stream channels are depicted in Appendix B and hydrologic data associated with this year's monitoring assessment Is provided In Appendix D 1.4 Other Information Summary information /data related to the occurrence of items such as beaver 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 Draft Monitoring Report Year 1 (2012) Page 2 UT Altamahaw Site, Alamance County Prepared by Ecological Engineering, LLP December, 2012 Restoration Plan) documents available on EEP's website. All raw data supporting the tables and figures in the appendices is available from EEP upon request. 2.0 METHODOLOGY This monitoring report follows methodology consistent with EEP's Procedural Guidance and Content Requirements for EEP Monitoring Reports (Version 1.3, dated 1/15/10), available at EEP's website (http: / /www.nceep.net). Vegetation assessments were conducted using the CVS -EEP protocol (Version 4.2). As part of this protocol, vegetation is assessed using 100- meter 2 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 -EEP 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. 3.0 REFERENCES Lee, Michael T., R.K. Peet, S.D.
