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 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 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 Monitoring Report Year 2 (2013) Page 1 UT Altamahaw Site, Alamance County Prepared by Ecological Engineering, LLP December 2013 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, three of the five vegetation plots met the minimum success criteria. Stem counts ranged from approximately 121 to 404 planted stems per acre and approximately 323 to 647 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. Several new planted stems were observed, which increased overall stem count numbers as compared with last year's reporting. 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 June and July 2013, at least one bankfull event occurred. Evidence of this event was wrack material above the bankfull indicators along the channel and cork shavings within the crest gage present at approximately 40 inches. No other bankfull events were indicated during 2013. 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 Monitoring Report Year 2 (2013) Page 2 UT Altamahaw Site, Alamance County Prepared by Ecological Engineering, LLP December 2013 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 EEP's website. All raw data supporting the tables and figures in the appendices is available from EEP upon request. Several issues were observed during the November field reconnaissance. These issues included (1) surface erosion along the existing cattle crossing, (2) mowing within the easement area, (3) lack of boundary signage and (4) erosion along the auxiliary spillway immediately outside of the Project Site. Surface erosion at the cattle crossing is a result from 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. Photographs in Appendix B depict this area of concern. Mowing within the easement area was observed along both sides of the riparian corridor associated with the UT. Figure 3 denotes the areas that have been recently mowed. The obvious purpose of the mowing was to remove and control vegetation along the existing fence lines. It extends inward approximately four to five feet from the woven wire. Boundary signage along the conservation easement area is limited and does not currently meet EEP guidelines. The lower portion of the auxiliary spillway immediately adjacent to the easement area has been eroded as a result of heavy rains from the storm events in June and July. The standpipe associated with the pond upstream of the project area is approximately 12 inches in diameter. More than nine inches of rain was recorded between June 5 and July 14. Excess flows were diverted to the auxiliary spillway. These flows moved a section of rip rap downstream towards the UT revealing the geotextile underlayment. Based on visual observations, water has also eroded a portion of the soil under the geotextile fabric. Photographs of this area are depicted in Appendix B. 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' 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. Monitoring Report Year 2 (2013) UT Altamahaw Site, Alamance County Prepared by Ecological Engineering, LLP Page 3 December 2013 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.
