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 included 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 first year of monitoring that took place in 2008. 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 first year monitoring counted an average of 701 stems per 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 first 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 Levels 2 and 3. Rock cross vanes, step pools, and riffle grade controls were used to control grade throughout the stream profiles. The stream was restored to B4c and C4 stream types. First year monitoring found the majority of the project to be functioning as designed. The surveyed profiles and cross-sections indicate that the project reaches are stable. In early September 2008, Tropical Storm Hanna brought five inches of rain to the site. This storm event created greater than bankfull discharges on all of the project reaches. Considering that construction was only recently completed at the site, there was the potential for some damage associated with this event. Upon inspection, only T1A suffered any damage that would require repair. These repairs will be conducted before the 2009 growing season. In addition to tropical storm Hanna there were four other storm events that created bankfull conditions. The project is on track to meeting the success criteria 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 year of monitoring, most of these plants were identified. Some of the previously unknown plants were dead, damaged, or missing and could not be identified during the first year monitoring. 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, which included Chinese privet (Ligistrum sinense) and tropical soda apple (Solanum viarum). Asian dayflower (Murdannia keisak) was present within the channel in UTCC3 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 706 stems/acre. The overall vegetation assessment found the site to be on track to meeting the vegetative success criteria. The vegetative monitoring results are displayed in Appendix A and the Current Conditions Plan View in Appendix C.

2.2

Stream Assessment

During the 2008 growing season, the flow in UTCC-3 was impeded by a debris blockage at the downstream limits of the site. The slow moving water allowed emergent vegetation to become established in the channel of this reach. The blockage has been removed and the location will continue to be monitored. The on-site stream gauge recorded five bankfull events throughout the growing season. The stream assessment found the stream to be stable overall. Periods of high flow caused isolated bed degradation in T1A-1 and T1A-2. One of these areas is visible on the longitudinal profile of T1A. Overland flow has caused scour on the floodplain on the left side of T1B. It is expected that this issue will stabilize as vegetation becomes established on the floodplain. The rest of the project’s stream banks, streambed, and floodplain have experienced little to no erosion throughout the project. The structures are performing well and as designed. The bed degradation will continue to be monitored to determine if corrective action are necessary. The stream assessment monitoring is described in Appendix B and the Current Conditions Plan View in Appendix C.
