EXECUTIVE SUMMARY / PROJECT ABSTRACT
Bushy Branch and an unnamed tributary in Raleigh, North Carolina’s Kentwood Park were identified as a restoration project in 2000. The project restored approximately 1,400 linear feet of channel, 1,070 feet on Bushy Branch and 350 feet on an unnamed tributary to Bushy Branch (UT to Bushy Branch). Construction was completed in 2002. The project goals and objectives are listed below. Goals • Stabilize the project streams. • Enhance the riparian corridor. • Improve water quality and aquatic habitat. Objectives • Installation of in-stream structures to define additional bed features. • Relocate a section of the stream in order to restore stream pattern. • Grade severely eroding banks and excavate new bankfull benches. • Install root wads to promote bank stability. • Revegetate the adjacent banks to promote the establishment of native plant communities. The restoration plan called for the removal of all existing problem vegetation along the stream banks and within the riparian buffer. The as-built survey found the original planting of native vegetation to be unsuccessful. To correct the initial failure, a remedial vegetation plan was designed and implemented in 2004. Remedial vegetation was planted at a density of 4,840 stems per acre in the streamside community and 680 stems per acre in the bottomland hardwood community. Three vegetation monitoring plots were established during the as-built survey. The fifth year of monitoring calculated an average of 1,740 planted stems/acre in the streamside community based on Plots 1 and 2 and 1,200 stems/acre in the bottomland hardwood community based on plot 3. The use of the park’s disc golf course has had an effect on the vegetation along the west side of the upper 200 feet of Bushy Branch. There are large, mature trees along this bank, but the impacts from frequent trampling have suppressed understory vegetation and led to compaction and poor cover in the near bank region. EEP implemented a supplemental planting effort earlier in the project’s history that included this area, but foot traffic remained high even with subsequent signage installed later. While the aesthetic and vegetation density of the near bank region in this area is clearly not as good as that further down the project’s extent, the large hardwood trees left in place provide a very significant stabilizing root mass. The initial condition of the banks in this area, which were somewhat steep in large part because these trees were saved had also exhibited some steepness and scour from the outset, but have not changed significantly over the monitoring period. Recently, EEP reported to KCI that they met again with the City of Raleigh and the staff responsible for its management to discuss the disc golf pressures and encroachment in some locations by park maintenance staff in order to reinforce protections moving into stewardship. In 2010 the city installed a closely spaced line of boulders and additional EEP signage on the easement boundary in this area. Microstegium (Microstegium vimineum) and kudzu (Pueraria montana) are present and are scattered over the project’s extent with a more concentrated area of kudzu near vegetation plot 3 at the lower end of the site. EEP has established a contract to control/suppress the kudzu during the spring/summer of 2010 with a follow up treatment in 2011. Aside from these invasive populations, the fifth year monitoring found the vegetation component of the project to be on track to meeting success criteria. The stream assessment completed during the fifth year of monitoring found Bushy Branch to be functioning as designed. Channel dimensions based on repeat cross-sections have not changed significantly over the monitoring period. There has been some localized bank erosion during the monitoring period, but the majority of these areas of bank erosion have not continued to degrade over the monitoring period. UT to Bushy Branch shows isolated areas of bed degradation, but exhibits stability across most of the tributary. Most of the in-stream structures are functioning across the project site, but

several have experienced stress evidenced by some erosion around vane arms. The structures that have been compromised are not in danger of causing wide-spread instability throughout the project. Summary information/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 the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the mitigation and restoration plan documents available on the EEPs website. All raw data supporting the tables and figures in the appendices are available upon request.

EXECUTIVE SUMMARY / PROJECT ABSTRACT
Bushy Branch and an unnamed tributary in Raleigh, North Carolina’s Kentwood Park were identified as a restoration project in 2000. The project restored approximately 1,400 linear feet of channel, 1,070 feet on Bushy Branch and 350 feet on an unnamed tributary to Bushy Branch (UT to Bushy Branch). Construction was completed in 2002. The project goals and objectives are listed below. Goals • Stabilize the project streams. • Enhance the riparian corridor. • Improve water quality and aquatic habitat. Objectives • Installation of in-stream structures to define additional bed features. • Relocate a section of the stream in order to restore stream pattern. • Grade severely eroding banks and excavate new bankfull benches. • Install root wads to promote bank stability. • Revegetate the adjacent banks to promote the establishment of native plant communities. The restoration plan called for the removal of all existing problem vegetation along the stream banks and within the riparian buffer. The as-built survey found the original planting of native vegetation to be unsuccessful. To correct the initial failure, a remedial vegetation plan was designed and implemented in 2004. Remedial vegetation was planted at a density of 4,840 stems per acre in the streamside community and 680 stems per acre in the bottomland hardwood community. Three vegetation monitoring plots were established during the as-built survey. The fifth year of monitoring calculated an average of 1,740 planted stems/acre in the streamside community based on Plots 1 and 2 and 1,200 stems/acre in the bottomland hardwood community based on plot 3. The use of the park’s disc golf course has had an effect on the vegetation along the west side of the upper 200 feet of Bushy Branch. There are large, mature trees along this bank, but the impacts from frequent trampling have suppressed understory vegetation and led to compaction and poor cover in the near bank region. EEP implemented a supplemental planting effort earlier in the project’s history that included this area, but foot traffic remained high even with subsequent signage installed later. While the aesthetic and vegetation density of the near bank region in this area is clearly not as good as that further down the project’s extent, the large hardwood trees left in place provide a very significant stabilizing root mass. The initial condition of the banks in this area, which were somewhat steep in large part because these trees were saved had also exhibited some steepness and scour from the outset, but have not changed significantly over the monitoring period. Recently, EEP reported to KCI that they met again with the City of Raleigh and the staff responsible for its management to discuss the disc golf pressures and encroachment in some locations by park maintenance staff in order to reinforce protections moving into stewardship. In 2010 the city installed a closely spaced line of boulders and additional EEP signage on the easement boundary in this area. Microstegium (Microstegium vimineum) and kudzu (Pueraria montana) are present and are scattered over the project’s extent with a more concentrated area of kudzu near vegetation plot 3 at the lower end of the site. EEP has established a contract to control/suppress the kudzu during the spring/summer of 2010 with a follow up treatment in 2011. Aside from these invasive populations, the fifth year monitoring found the vegetation component of the project to be on track to meeting success criteria. The stream assessment completed during the fifth year of monitoring found Bushy Branch to be functioning as designed. Channel dimensions based on repeat cross-sections have not changed significantly over the monitoring period. There has been some localized bank erosion during the monitoring period, but the majority of these areas of bank erosion have not continued to degrade over the monitoring period. UT to Bushy Branch shows isolated areas of bed degradation, but exhibits stability across most of the tributary. Most of the in-stream structures are functioning across the project site, but

several have experienced stress evidenced by some erosion around vane arms. The structures that have been compromised are not in danger of causing wide-spread instability throughout the project. Summary information/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 the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the mitigation and restoration plan documents available on the EEPs website. All raw data supporting the tables and figures in the appendices are available upon request.
