Success Criteria Collins Creek Stream Restoration Site Feature Success Criteria Stream Minimal changes to the measured stream characteristics, demonstrating system stability At least two bankfull events occurring in separate years over the course of the monitoring period Vegetation Average of 260 stems /acre, as indicated by permanent vegetation plots after 5 years of monitoring C.

Associates of North Carolina 2012 - MY05 1.0 EEP RECOMMENDATIONS AND CONCLUSIONS The stream assessment found the stream to be generally stable, with no significant changes from the previous monitoring year The surveyed profiles and cross - sections reveal few significant changes between fourth and fifth -year monitoring The fifth year of monitoring found the majority of the project to be functioning as designed Small isolated areas of bank erosion have been noted on the Current Condition Plan View (CCPV), but there are no systematic problems that indicate that the project streams are becoming unstable Two beaver dams were built on UTCC in 2011 Both of these beaver dams have been breached and were fully removed in 2012 Another large beaver dam has been constructed since the removal of these two and will be removed in early 2013 With multiple bankfull events since construction, the stream has met the success criterion of at least two bankfull events occurring in separate years over the course of the monitoring period The floodplain, stream banks, and riparian buffer have isolated areas with sparse vegetation, but overall they are well vegetated Some scattered populations of invasive species have been identified in the floodplam and surrounding areas These include Chinese privet (Ltgustrum sinense) and multiflora� rose (Rosa multiflora), which were treated by cutting and spraying in spring 2013 The monitored vegetation plots within the stream buffer revealed that the planted vegetation is growing well with an average of 559 stems /acre None of the monitoring plots had calculated planted stem densities less than 260 stems /acre The overall vegetation assessment found the site has met the vegetative success criteria for monitoring year 5 Overall the stream and the site's vegetation condition indicate that it is on a path to success The EEP recommends that this site be closed out Collins Creek Stream Restoration KCI Associates of North Carolina 2012 - MY05 Collins Creek Stream Restoration KCI Associates of North Carolina Closeout Report Post - Construction Photos MY -05 PP #3A - MY05 - 12/14/12 PP #6B - MY05 - 12/14/12 PP #IOC - MY05 - 12/14/12 PP #3B - MY05 - 12/14/12 PP #9B - MY05 - 12/14/12 PP #12A - MY05 - 12/14/12 Collins Creek Stream Restoration KCI Associates of North Carolina Closeout Report Appendix A Watershed Planning Summary The Collins Creek site is not within an EEP watershed planning area.
