Prlect Setting and Backaround Summary
The Silver Creek stream restoration project is located near Morganton, in Burke County, North Carolina Pnor to restoration, channelization and cattle intrusion
resulted in vegetative denuding and bank destabilization The vertical to undercut unstable streambanks were contributing large volumes of suspended sediment and
bedload material to the larger Silver Creek watershed The restoration of project streams re- established geomorphic features consistent with natural stream channel
characteristics Elements of the restoration included stable channel pattern, profile, and dimension consistent with reference reach conditions quantified within the
Silver Creek watershed, upstream of the project on Brindle Creek. 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

EEP Recommendation and Conclusion
The Silver Creek Site has met 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

APPENDIX A - Watershed 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.
