The Site is located within United States Geological Survey Hydrologic Unit 03020201065010 (North Carolina Division of Water Quality Subbasin 03- 04 -08) of the Neuse River Basin. The Site was identified to assist the North Carolina Ecosystem Enhancement Program in meeting stream and buffer restoration goals. Primary activities at the Site included stream restoration and riparian buffer restoration by stabilizing stream banks, installing in- stream structures, adjusting stream plan form, and replanting riparian areas with native vegetation. Project restoration efforts provided 640 Stream Mitigation Units, 14.9 Buffer Mitigation Units, and 14.7 Nutrient Offset Credit. This project was instituted prior to October 11, 2007 and therefore is eligible for riparian buffer restoration credit up to 200 feet from the top of bank of all perennial and intermittent waterways within the Site. This report summarizes data for year 4 (2010) monitoring. The primary components of the restoration project included the following. • Construct a stable, riffle -pool stream channel capable of moving sediments supplied by the watershed so the channel neither aggrades nor degrades. • Stabilize stream banks, install in- stream structures, adjust stream planform, and replant riparian areas with native vegetation. • Improve water quality and reduce lateral erosion and bed degradation of stream channels by establishment of riparian vegetation. • Enhance aquatic and terrestrial wildlife habitat through improvements to stream water quality including improved oxygen levels, reduced sediments and nutrients, and varied stream bed features. Success criteria dictate that an average density of 320 stems per acre of planted hardwoods must be surviving after five monitoring years in accordance with North Carolina Division of Water Quality Administrative Code 15A NCAC 0213.0242 (Meuse River Basin, Mitigation Program for Protection and Maintenance of Existing Riparian Buffers) (NCDWQ 2007). Based on the number of stems counted, average densities were measured at 526 planted stems per acre surviving in year 4 (2010). The dominant species identified at the Site were planted stems of green ash (Fraxinus pennsylvanica), cherrybark oak (Quercus pagoda), and willow oak (Quercus phellos). In addition, each individual plot met success criteria based on planted stems alone with the exception of Plot 14, which had 283 planted stems per acre. However, when counting appropriate natural recruit species stems such as box elder (Acer negundo) and overcup oak (Quercus lyrata) this plot was well -above success criteria. Success criteria for stream restoration reaches should show little to no change from the as -built channel over the five -year monitoring period. Year 4 (2010) monitoring measurements indicate that there have been minimal changes in both the longitudinal profile and cross - sections as compared to as -built data. In addition, two bankfu11 event were documented to occur in November 2009 and February 2010 for a total of six documented bankfull events with events occurring in multiple monitoring years. In summary, the Site achieved success criteria for vegetation and stream attributes in the Fourth Monitoring Year (2010). Summary information and 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 table and figures within this report's appendices. Narrative background and supporting information formerly found in these reports can be found in the mitigation and restoration plan documents available on EEPs website. All raw data supporting the tables and figures in the appendices is available from EEP upon request. Bold Run (final) Axiom Environmental, Inc.

Five plots are located in the streamside riparian buffer planting zone and ten plots are located within the remaining buffer area. Plots were surveyed in June 2010 for the year 4 (2010) monitoring season. Sampling was conducted as outlined in the CVS -EEP Protocol for Recording Vegetation, Version 4.0 (Lee et al. 2006) ( http: / /cvs.bio.unc.edu /methods.htm); results are included in Appendix C. The taxonomic standard for vegetation used for this document was Flora of the Carolinas, Virginia, Georgia, and Surrounding Areas (Weakley 2007). The locations of vegetation monitoring plots are depicted on Figure 2 in Appendix A. 2.2 Stream Assessment Five permanent cross - sections were established after construction was completed. Measurements of each cross - section include points at all breaks in slope including top of bank, bankfull, and thalweg. Riffle cross - sections are classified using the Applied Fluvial Morphology ( Rosgen 1996) stream classification system. Longitudinal profile measurements of the entire Site restoration reaches include thalweg and water surface; with each measurement taken at the head of facets (i.e. riffle, run, pool, and glide) in addition to the maximum pool depth. Visual assessment of in- stream structures was conducted to determine if failure has occurred. Failure of a structure may be indicated by collapse of the structure, undermining of the structure, abandonment of the channel around the structure, and/or stream flow beneath the structure. 3.0 REFERENCES Lee, Michael T., R.K.
