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. Prior to restoration activities, the Site was utilized for livestock pasture. Land use modifications including the removal of riparian vegetation and hoof shear to stream banks resulted in degraded water quality and unstable channel characteristics (stream entrenchment, erosion, and bank collapse). 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. 2011 encroachment fully re- sprouted on its own and did not require supplemental planting. Beaver Management In 2008 a large beaver dam was observed at the downstream extent of the Site restoration reach near the confluence with New Light Creek. Beaver management was initiated at the time and has continued as needed. Goals and Objectives • 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 Vegetation: An average density of 320 stems per acre must be surviving after five monitoring years in accordance with North Carolina Division of Water Quality Administrative Code 15A NCAC 02B.0242 (Meuse River Basin, Mitigation Program for Protection and Maintenance of Existing Riparian Buffers) (NCDWQ 2007). Vegetation Success Criteria were met throughout the 5 -year monitoring period. Stream: Stream restoration reaches should show little to no change from the as -built channel over the five -year monitoring period. Stream Success Criteria were met throughout the 5 -year monitoring period. Hvdroloev: A minimum of two bankfull events documented in separate monitoring years. Hydrological Success Criteria were met throughout the 5 -year monitoring period.

Page 11 of 19 Data Summary In summary, the Site has met mitigation success criteria for stream, buffer, and nutrient offset for the entire five -year monitoring period. Vegetation: tation: Based on the number of stems counted, average densities were measured at 648 planted stems per acre surviving in year 5 (2011). The dominant species identified at the Site were planted stems of green ash (Fraxinus pennsylvanica), oak species (Quercus spp.), and elm species (Ulmus spp.). In addition, each individual plot met success criteria based on planted stems alone in each monitoring year with the exception of Plot 14 in Year 4 -5 (2010- 2011), which was one stem shy in both years with 283 planted stems per acre. When counting appropriate natural recruit species stems such as box elder (Acer negundo) and green ash this plot was well -above success criteria with 931 and 850 total stems per acre, respectively.

Page 12 of 19 Planted and Total Stems Baseline stem counts (Year 0) are misleading when counting stems for riparian buffer success criteria. The majority of stems were marked as unknown since baseline counts were done during the dormant period; the stems were later identified during Year 1 (2007) monitoring. Total stem counts increased throughout Years 1 -5 (2007 -2011) as the result of resprouts of planted stems within plots adjacent to the stream. During the first several years these stems encountered heavy herbivory by beaver and deer, therefore, the stem would be considered missing one year and found the next. These stems have much larger diameter stems near the base of the plant relative to the plant diameter '' /� -1 foot from the ground.

Page 13 of 19 EEP Recommendation and Conclusion The Bold Run site has demonstrated success in stream, riparian buffer and nutrient offset buffer restoration. EEP recommends closing out this site with the proposed Stream Mitigation Units of 1134. Contingencies No contingencies recommended at this time. Page 14 of 19 Pre - Construction Photos 2006 Post - Construction Photos Page 15 of 19 APPENDIX B — Land Ownership and Protection The Bold Run Creek project is located in HUC 03020201065010, the New Light Creek watershed that was originally designated as a Targeted Local Watershed (TLW) in the 2002 Neuse RBRP (NCEEP, 2002) and continues this designation in the 2010 Neuse RBRP (NCEEP, 2010). At nearly 77 %, this watershed has one of the highest forest cover percentages in the upper Neuse basin. The watershed exhibits some level of impacts due to agriculture and livestock maintenance. The 2010 RBRP recommends agricultural best management projects to improve water quality conditions here. The Bold Run Creek project restores a significant amount of riparian buffer and restores stream pattern to help reduce flow energy, thereby reducing impacts of agricultural runoff to the watershed. EEP has no additional projects in this TLW. According to the 2009 Neuse River Basinwide Water Quality Plan (NCDWQ, 2009), during the 2005 benthic macroinvertebrate community sampling approximately 0.5 miles downstream of the Bold Run Creek project site, "instream habitat [was] sparse with only a few riffle areas and eroded stream banks" and the stream "was very turbid in this area". Also, the benthic community indicated a decline in water quality evidenced by a stream bioclassification of "good" during and prior to 2001 and "good- fair" in 2005 and 2010 benthic sampling events. The 2010 data reflect the lowest number of EPT species present since the initial sampling in 1995. This project restores buffer function for the length of the stream restoration and reduces nutrient and sediment inputs via increased infiltration. These functional improvements are beneficial to the benthic community and support the TLW goals. References: North Carolina Division of Water Quality, Neuse River Basinwide Water Quality Plan, 2009.
