In -stream structures were constructed to provide grade control, streambank stabilization, and aquatic habitat features Restoration reconnected project stream channels to functional tloodplams with extensive riparian plantings Goals and Obiectrves • Stable stream channels with features indicative of a biologically diverse environment • Reversing the effects of channelization and stabilizing eroding and undercut stream banks • Restored connections between the bankfull width and floodprone width of the channels by restoring (excavating) the floodprone area • Improved physical aquatic habitat features, including in- stream habitat features • Minimization of existing agricultural land use impacts to the stream • Long -term protection of the stream corridors, including Re- vegetation of the riparian corridors with native trees and shrubs and preservation of existing vegetated corridors Success Criteria Performance Criteria Noted Project Success (cifing Monitonng Re its Minimal or negligible development of in- stream bar deposits Minimal channel aggradation has been observed throughout the 5 -year monitoring period There are current) no m -stream bar deposits threatening the stability of the channel Minimal or negligible change in channel pattern, profile and dimension in The channels for the main stem and UT -A have maintained relative consistency with the as -built comparison to As -Built conditions dimensions, as shown in the tables on the following page UT -B and UT -C were not monitored for geomorphic properties Maintenance of floodplam connectivity The entrenchment ratios for the main stem and UT -A have remained consistent throughout the 5- ear mon►torm period, as shown in the tables on the following page Target density of 320 stems per acre after 3 years and 260 stems per acre The average planted live stem density across all of the vegetation monitoring plots for Silver Creek after 5 years for planted woody vegetation and UT -A is 397 stems per acre The lowest planted density is 284 stems per acre When considering all live stems, those numbers increase to 608 and 446, respectively 401 Water Quality Certification Monitoring for UT -B and Q* I The average live stem density in the monitoring lots for these channels is 668 stems per acre *Various project impacts associated directly or indirectly with the restoration project required a separate 401 certification through the DWQ, which stipulated monitoring for vegetative success along UT -B and UT -C Page 2 of 29 MITIGATION SUMMARY TABLE Restoration Pre Construction Mitigation Watershed Acreage As -Built Linear Mitigation Ratio Mitigation Units Segment/Reach linear feet Approach S Mt Footage /Acreage — (SMU/WMU) STREAM — — ` ' t Previous Revised Previous Revised Previous Revised Previous Revised Silver Creek Mamstem 3,043 R Same 826 2,905 Same 10 Same 2,905 Same UT -A 1,508 R Same 0 075 1,552 1,537 10 Same 1,552 1,537 UT -B 66 P E2 ** N/A 66 Same 5.0 2 5 ** 26.4 264 UT -C 48 P E2 ** N/A 48 Same 5.0 2 5 ** 10 19.2 UT -D 52 P Same N/A 52 Same 5.0 Same 10 Same TOTALS= 4,717 4,623 4,608 4,490 4,498 "Previous" — from the Mitigation and Monitoring Plan reports, "Revised" — changed for the close -out report * Reflects reduction of 15 feet for overhead utility line along UT -A (50% of presumed 30 -foot maintenance easement) * *Change made to account for constructed profile adjustments and channel stabilization along UT -13 and UT -C within the limits of the conservation easement MITIGATION UNIT TOTALS 'Stream atign Units Riparian Wetland Noi- riparian Total Wetland � J' °``�" ]der Nutrient "get ASMM Units.

its success criteria established in the mitigation plan during the 5- year monitoring period Subsequent to the submission of the Year 5 monitoring report, it was determined the location of the fencing along the protect corridor was not entirely consistent with the location of the conservation easement To remedy this situation, the conservation easement was re- staked by a professional surveyor and, where necessary, the fencing was relocated Presently, the fencing along UT -A extends upstream beyond the terminus of the conservation easement to prevent cattle intrusions that would otherwise impact the performance of the stream restoration As such, the upstream terminus of the conservation is also marked in the field for reference purposes In addition, supplemental planting and invasive species management has occurred following the Year 5 monitoring event along portions of the main stem and UT -A to further bolster the performance of those channels The Mitigation and Monitoring Plans completed for this project all identify a total of 4,490 SMUs for Restoration along Silver Creek main stem and UT -A, and Preservation of short reaches of UT -B, UT -C and UT -D where they confluence with Silver Creek The total number of SMUs for the project has been updated in this report based on the factors listed below The total length of the restoration along UT -A has been reduced by 15 feet to account for an overhead utility line that crosses the channel and where clearing of vegetation beneath the line has been observed The deduction represents 50% of the presumed total maintenance width of 30 feet There has been no evidence found of an actual easement for the utility line The original credit designation (mitigation approach) for UT -B and UT -C was Preservation However, physical improvements were made to these channels within the protective easement as part of the original project construction These improvements affected the stream profile and also created a stable transition of these tributanes to the main stem (see photos) The vegetative success of these channels has been monitored and documented throughout the 5 -year monitoring period, however, no specific geomorphic data has been collected Therefore, we believe that the work completed for these small reaches at a minimum justifies a minimum of 2 5 1 credit ratio Based on these determinations, EEP in conjunction with Wetlands Resource Center recommends closeout of the Silver Creek project at 4,498 SMUs Contingencies None Page 16 of 29 Pre - Construction Photos Page 17 of 29 Post - Construction

Planning Summary 92218- Silver Creek (Conway) The Silver Creek - Conway project is located within a designated EEP Targeted Local Watershed (TLW) within the upper Catawba River subbasin (Cataloging Unit, 03050101). The Silver Creek TLW (Hydrologic Unit 03050101050050) is 61 square miles in area and is located in Burke County, including portions of the City of Morganton and the primarily rural landscape stretching southwest of Morganton to the South Mountains. Potential watershed stressors identified within this TLW -- as reported in the Upper Catawba River Basin Restoration Priorities document (EEP. 2009) — include a large number of animal/livestock operations, degraded (non - forested) riparian buffers and stormwater runoff associated with significant impervious cover in the lower portion of the watershed within Morganton. Nutrient and sediment inputs associated with agricultural lands, unstable stream banks, livestock access and past mining operations are likely to be additional important functional stressors. This TLW is also rich in watershed assets, such as natural heritage element occurrences (rare species) and conserved lands, especially in the headwater portions around the South Mountains. Protection of the water supply waters of the mainstem Catawba River through Morganton is also an important goal of any restoration/enhancement or preservation efforts within this hydrologic unit. In addition to the Silver Creek - Conway Project, EEP has four additional projects within this TLW (see map below), including Silver Creek (336) and Upper Silver Creek (94645), both located just upstream of the Conway project site. The three projects on Silver Creek together amount to over 16,000 feet of stream restoration/enhancement, including buffer restoration, bank stabilization and livestock exclusion fencing; all of which will contribute to the reduction of sediment and nutrient inputs to Silver Creek.
