Collins Creek Stream Restoration
KCI Associates of North Carolina 2009 - MY02
EXECUTIVE SUMMARY The Collins Creek Stream Restoration Site is located in the Piedmont physiographic province in Orange County, North Carolina. The project will provide mitigation for stream impacts within the 8-digit hydrologic cataloging unit 03030002 in the Cape Fear River Basin by restoring and enhancing 9,453 linear feet on an Unnamed Tributary to Collins Creek (UTCC) and other associated tributaries, generating 8,933 stream mitigation units (SMU’s.) The goals of the project include improving water quality in this agricultural stream system and creating high-quality aquatic and terrestrial habitat along an interconnected forested riparian corridor. In order to reach these goals, the project objectives included restoring and enhancing 9,453 linear feet of stable stream channel with the appropriate pattern, profile, and dimension that can handle the hydrologic input from the surrounding drainages; planting a functional Piedmont Alluvial Forest floodplain community along with Mesic Mixed Hardwood Forest to develop an effective riparian buffer, and removing cattle and horses from the riparian areas through livestock exclusion fencing. This report describes the results from the findings of the second year of monitoring that took place in 2009. The riparian buffer was planted with 17 different species of bare root trees and shrubs and four different species of live stakes. Fifteen vegetation monitoring plots were established during the as-built survey. Riparian vegetation must meet a minimum survival success rate of 320 stems/acre after five years. The plots were monitored following the CVS-EEP monitoring protocol and the second-year monitoring counted an average of 623 stems/ acre. Isolated invasive species were noted in the restored stream buffer and will continue to be monitored to determine if corrective action is necessary. The second-year monitoring found the vegetation component of the project to be on track to meeting the success criterion. The stream restoration included ten separate reaches, which were enhanced and restored based on a combination of Priority Approaches 2 and 3. Rock cross vanes, step pools, and riffle grade controls were used to control grade throughout the stream profiles. The streams were restored to B4c and C4 stream types. The second year of monitoring found the majority of the project to be functioning as designed. Small areas of bank erosion and streambed degradation have been noted in this report, but there are no systematic problems that indicate that the project streams are unstable or becoming so. In 2009, there were six bankfull events at the site. The project is on track to meeting the success criterion of at least two bankfull events in five years with each occurring in different monitoring periods.

PROJECT BACKGROUND
1.1
Project Objectives The goals and objectives of the restoration project are as follows: Restoration Goals: • Improve water quality by reducing nutrient and sediment inputs. • Create high-quality aquatic and terrestrial habitat along an interconnected forested riparian corridor. Restoration Objectives: • Plant a functional Piedmont Alluvial Forest floodplain community along with Mesic Mixed Hardwood Forest to develop an effective riparian buffer. • Restore stable stream reaches that can handle the hydrologic input from the surrounding drainages. • Remove cattle and horses from the riparian areas through livestock exclusion fencing.
1.2
Project Structure, Restoration Type, and Approach The project streams had become degraded primarily through poor grazing management and vegetation removal. Historic aerial photographs show that the land surrounding the streams has been in rangeland for at least 65 years and cattle and horses have had access to the stream up until the restoration construction. The streams had experienced bank erosion, which led to excessive sediment throughout the site. Bed degradation and aggradation were also evident throughout the different project reaches. All of the reaches exhibited areas of vertical instability. Restoration and enhancement of 9,453 linear feet of channel was accomplished utilizing a combination of Priority 2 and 3 approaches (Table 1). UTCC-1 (Station 10+00 to 15+00) was enhanced and UTCC-2 (Station 15+00 to 24+00) and UTCC-3 (Station 24+00 to 33+49) were restored using a Priority 2 approach. The enhancement and restoration of a C4 channel with a sinuosity of 1.34 was accomplished by building a bankfull channel with a higher width/depth ratio than the existing stream, connecting it to a floodplain (bank height ratio=1.0), and creating distinct bed features by adding pools and riffles to the profile. UTCC-1 was enhanced by altering the stream cross-section and profile. UTCC-2 and UTCC-3 were restored by altering the stream cross-section, profile, and planform. In some instances, restoration was accomplished within the same belt-width and in the location of the pre-restoration channel. In the locations where the stream stayed on-line, the stream had been so drastically degraded that there was no form to the channel and the design was able to preserve one streambank and create a new bank and pattern on the opposite side of the stream.
1.3
Location and Setting The project site is located in a rural setting within the Carolina Slate Belt ecoregion of the Piedmont physiographic province. The site drains to the southeast with a contributing drainage area of approximately 2.6 square miles at the downstream project limits (Figure 3). The watershed’s southern boundary runs along NC 54. The northern boundary is below the intersection of Dodsons Crossroads and Dairyland Road. The eastern and western boundaries of the watershed are formed by the topography of the rural landscape. The project site is spread over three different parcels of private property. The site is located off of Dodsons Crossroads six miles west of Carrboro, North Carolina in Orange County. Specifically, the site is approximately 800 feet north of the intersection of Dodsons Crossroads and NC 54

(Figure 1). The project is centered at approximately 35.9313 degrees north and 79.1788 degrees west (WGS84). To reach the site from Raleigh, proceed west on Interstate 40. Take Exit 273 and travel west on NC 54. Continue west on NC 54 as it joins NC 15-501 and then later splits off from NC 15-501. Approximately 7.5 miles after splitting off from NC 15-501, turn right onto Dodsons Crossroads. The project is accessible from a gravel driveway approximately 0.3 mile on the left.

PROJECT CONDITIONS AND MONITORING RESULTS
2.1
Vegetation Assessment
The planted vegetation on the site is growing well. Due to the baseline vegetation monitoring occurring while the plants had not yet leafed out, some of the plants could not be identified initially and they were recorded as unknown. During the first and second years of monitoring, most of these plants were identified. Some of the previously unknown plants were dead, damaged, or missing and could still not be identified. These plants were again recorded as unknown. 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 floodplain and surrounding areas. These include Chinese privet (Ligustrum sinense), multiflora rose (Rosa multiflora), and tropical soda apple (Solanum viarum). Asian dayflower (Murdannia keisak) was present within the channel in UTCC-3 and other isolated areas. Although they are not a problem at this time, these populations will continue to be monitored to determine if invasive control is required in the future. The monitored vegetation plots within the stream revealed that the planted vegetation is growing well with an average of 623 stems/acre. There is one monitoring plot (Plot 15) that has a calculated planted stem density less than 320 stems/acre. This is not seen as problematic given the high potential for desirable volunteers to become established in the plots and across the site. Like natural vegetative communities, some areas will have slightly higher densities than others, but the data from the vegetation monitoring plots reveal that the site has an adequate average stem density. In the third year of monitoring KCI will use the Level 2 CVS-EEP vegetation monitoring protocol to quantify the number of volunteer woody stems. The vegetation assessment found the site to be on track to meeting the vegetative success criteria. The vegetative monitoring results are displayed in Appendix A.
2.2
Stream Assessment
During the 2009 growing season, the project streams have been functioning as designed. There are isolated areas of bank erosion, which have been noted on the Current Condition Plan View (CCPV). The on-site stream gauge recorded six bankfull events throughout the growing season. The stream assessment found the stream to be stable overall. The surveyed profiles and cross-sections reveal few changes from last year’s and this year’s monitoring. It appears that there was a survey error that produced an approximate two-foot shift in this year’s plot of Cross-Section 11. The apparent change is evident in the cross-section plot in Appendix B. After the third-year monitoring data are collected and this situation is verified as a survey error, the plot will be realigned to coincide with the previous survey data. The structures are performing well and as designed. Prior to monitoring in 2009, several stream maintenance issues were addressed. T1A and T2 each had two constructed riffles installed and the banks adjacent to the rock ford crossing through UTCC were repaired and the ford was stabilized. The locations of these maintenance actions can be found on the CCPV. Additional stream assessment data can be found in Appendix B and the Current Condition Plan View in Appendix C.

Collins Creek Stream Restoration
KCI Associates of North Carolina 2009 - MY02
EXECUTIVE SUMMARY The Collins Creek Stream Restoration Site is located in the Piedmont physiographic province in Orange County, North Carolina. The project will provide mitigation for stream impacts within the 8-digit hydrologic cataloging unit 03030002 in the Cape Fear River Basin by restoring and enhancing 9,453 linear feet on an Unnamed Tributary to Collins Creek (UTCC) and other associated tributaries, generating 8,933 stream mitigation units (SMU’s.) The goals of the project include improving water quality in this agricultural stream system and creating high-quality aquatic and terrestrial habitat along an interconnected forested riparian corridor. In order to reach these goals, the project objectives included restoring and enhancing 9,453 linear feet of stable stream channel with the appropriate pattern, profile, and dimension that can handle the hydrologic input from the surrounding drainages; planting a functional Piedmont Alluvial Forest floodplain community along with Mesic Mixed Hardwood Forest to develop an effective riparian buffer, and removing cattle and horses from the riparian areas through livestock exclusion fencing. This report describes the results from the findings of the second year of monitoring that took place in 2009. The riparian buffer was planted with 17 different species of bare root trees and shrubs and four different species of live stakes. Fifteen vegetation monitoring plots were established during the as-built survey. Riparian vegetation must meet a minimum survival success rate of 320 stems/acre after five years. The plots were monitored following the CVS-EEP monitoring protocol and the second-year monitoring counted an average of 623 stems/ acre. Isolated invasive species were noted in the restored stream buffer and will continue to be monitored to determine if corrective action is necessary. The second-year monitoring found the vegetation component of the project to be on track to meeting the success criterion. The stream restoration included ten separate reaches, which were enhanced and restored based on a combination of Priority Approaches 2 and 3. Rock cross vanes, step pools, and riffle grade controls were used to control grade throughout the stream profiles. The streams were restored to B4c and C4 stream types. The second year of monitoring found the majority of the project to be functioning as designed. Small areas of bank erosion and streambed degradation have been noted in this report, but there are no systematic problems that indicate that the project streams are unstable or becoming so. In 2009, there were six bankfull events at the site. The project is on track to meeting the success criterion of at least two bankfull events in five years with each occurring in different monitoring periods.

PROJECT BACKGROUND
1.1
Project Objectives The goals and objectives of the restoration project are as follows: Restoration Goals: • Improve water quality by reducing nutrient and sediment inputs. • Create high-quality aquatic and terrestrial habitat along an interconnected forested riparian corridor. Restoration Objectives: • Plant a functional Piedmont Alluvial Forest floodplain community along with Mesic Mixed Hardwood Forest to develop an effective riparian buffer. • Restore stable stream reaches that can handle the hydrologic input from the surrounding drainages. • Remove cattle and horses from the riparian areas through livestock exclusion fencing.
1.2
Project Structure, Restoration Type, and Approach The project streams had become degraded primarily through poor grazing management and vegetation removal. Historic aerial photographs show that the land surrounding the streams has been in rangeland for at least 65 years and cattle and horses have had access to the stream up until the restoration construction. The streams had experienced bank erosion, which led to excessive sediment throughout the site. Bed degradation and aggradation were also evident throughout the different project reaches. All of the reaches exhibited areas of vertical instability. Restoration and enhancement of 9,453 linear feet of channel was accomplished utilizing a combination of Priority 2 and 3 approaches (Table 1). UTCC-1 (Station 10+00 to 15+00) was enhanced and UTCC-2 (Station 15+00 to 24+00) and UTCC-3 (Station 24+00 to 33+49) were restored using a Priority 2 approach. The enhancement and restoration of a C4 channel with a sinuosity of 1.34 was accomplished by building a bankfull channel with a higher width/depth ratio than the existing stream, connecting it to a floodplain (bank height ratio=1.0), and creating distinct bed features by adding pools and riffles to the profile. UTCC-1 was enhanced by altering the stream cross-section and profile. UTCC-2 and UTCC-3 were restored by altering the stream cross-section, profile, and planform. In some instances, restoration was accomplished within the same belt-width and in the location of the pre-restoration channel. In the locations where the stream stayed on-line, the stream had been so drastically degraded that there was no form to the channel and the design was able to preserve one streambank and create a new bank and pattern on the opposite side of the stream.
1.3
Location and Setting The project site is located in a rural setting within the Carolina Slate Belt ecoregion of the Piedmont physiographic province. The site drains to the southeast with a contributing drainage area of approximately 2.6 square miles at the downstream project limits (Figure 3). The watershed’s southern boundary runs along NC 54. The northern boundary is below the intersection of Dodsons Crossroads and Dairyland Road. The eastern and western boundaries of the watershed are formed by the topography of the rural landscape. The project site is spread over three different parcels of private property. The site is located off of Dodsons Crossroads six miles west of Carrboro, North Carolina in Orange County. Specifically, the site is approximately 800 feet north of the intersection of Dodsons Crossroads and NC 54

(Figure 1). The project is centered at approximately 35.9313 degrees north and 79.1788 degrees west (WGS84). To reach the site from Raleigh, proceed west on Interstate 40. Take Exit 273 and travel west on NC 54. Continue west on NC 54 as it joins NC 15-501 and then later splits off from NC 15-501. Approximately 7.5 miles after splitting off from NC 15-501, turn right onto Dodsons Crossroads. The project is accessible from a gravel driveway approximately 0.3 mile on the left.

PROJECT CONDITIONS AND MONITORING RESULTS
2.1
Vegetation Assessment
The planted vegetation on the site is growing well. Due to the baseline vegetation monitoring occurring while the plants had not yet leafed out, some of the plants could not be identified initially and they were recorded as unknown. During the first and second years of monitoring, most of these plants were identified. Some of the previously unknown plants were dead, damaged, or missing and could still not be identified. These plants were again recorded as unknown. 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 floodplain and surrounding areas. These include Chinese privet (Ligustrum sinense), multiflora rose (Rosa multiflora), and tropical soda apple (Solanum viarum). Asian dayflower (Murdannia keisak) was present within the channel in UTCC-3 and other isolated areas. Although they are not a problem at this time, these populations will continue to be monitored to determine if invasive control is required in the future. The monitored vegetation plots within the stream revealed that the planted vegetation is growing well with an average of 623 stems/acre. There is one monitoring plot (Plot 15) that has a calculated planted stem density less than 320 stems/acre. This is not seen as problematic given the high potential for desirable volunteers to become established in the plots and across the site. Like natural vegetative communities, some areas will have slightly higher densities than others, but the data from the vegetation monitoring plots reveal that the site has an adequate average stem density. In the third year of monitoring KCI will use the Level 2 CVS-EEP vegetation monitoring protocol to quantify the number of volunteer woody stems. The vegetation assessment found the site to be on track to meeting the vegetative success criteria. The vegetative monitoring results are displayed in Appendix A.
2.2
Stream Assessment
During the 2009 growing season, the project streams have been functioning as designed. There are isolated areas of bank erosion, which have been noted on the Current Condition Plan View (CCPV). The on-site stream gauge recorded six bankfull events throughout the growing season. The stream assessment found the stream to be stable overall. The surveyed profiles and cross-sections reveal few changes from last year’s and this year’s monitoring. It appears that there was a survey error that produced an approximate two-foot shift in this year’s plot of Cross-Section 11. The apparent change is evident in the cross-section plot in Appendix B. After the third-year monitoring data are collected and this situation is verified as a survey error, the plot will be realigned to coincide with the previous survey data. The structures are performing well and as designed. Prior to monitoring in 2009, several stream maintenance issues were addressed. T1A and T2 each had two constructed riffles installed and the banks adjacent to the rock ford crossing through UTCC were repaired and the ford was stabilized. The locations of these maintenance actions can be found on the CCPV. Additional stream assessment data can be found in Appendix B and the Current Condition Plan View in Appendix C.
