Executive Summary The Ellerbe Creek stream restoration a project is located on the Hillandale Golf Course in Durham, North Carolina just east of the intersection of U.S. 15/501 and Interstate 85 (I- 85). The project has restored 6,279 linear feet of the perennial stream in the Neuse River Basin (USGS HUC 03020201050010). The drainage area for the site covers approximately 5,635 acres (Stantec 2005a). Several unnamed tributaries enter Ellerbe Creek upstream of the restoration site. Project construction began in January 2004 and was completed in December of the same year. The fourth year of monitoring was completed in September 2008. RJG&A's initial 2008 qualitative evaluation was conducted on 16 April. Quantitative vegetation and geomorphologic data were collected between 24 July and 18 September. Stream visual assessment was conducted on 18 September 2007. The restoration project appears to have met its design goals. No significant geomorphologic changes have occurred during the fourth monitoring year. The average planted woody stem density (798 per acre) has exceeded the vegetation restoration goal of 320 stems per acre. This was calculated from data collected in 11 permanent monitoring plots using the EEP 2004 Stem Counting Protocol. Although vegetation problems areas continue to exist throughout the restoration in the • form of rill and gully erosion and bare floodplain areas, they are smaller in area in 2008. The stream problems areas continue to center around the presence of beaver (Castor canadensis) and beaverdams. Other problem areas involving bank scour/slump and aggradation are less in size than the previous year. II. Project Background A. Project Objectives The objectives of the Ellerbe Creek Stream restoration project are to: 1. Establish a new floodplain at a lower elevation and connecting the stream to the new floodplain; 2. Reduce erosion and sedimentation; 3. Provide wildlife habitat through the creation of a more natural riparian buffer; 4. Improve aquatic habitat with the use of natural material stabilization structures and a riparian buffer; and 5. Improve water quality within Ellerbe Creek (Stantec 2005a). B. Project Structure, Restoration Type, and Approach A Priority 2 stream restoration was used for the most of project's length to establish a new floodplain, improve sediment transport capability, restore wildlife habitat, and improve water quality. Some stream enhancement was done in the Croasdaile, is Ellerbe Creek Stream Restoration 2008 Final Monitoring Report Project #127 Year 4 of 5 RJG&A Page 4 • • and Hillandale Road, and terminates approximately 300 feet west of Albany Street. Sprunt Avenue parallels most of the site to the south. Indian Trail parallels the Albany reach to the north (Figure 1). The Croasdaile reach is along an unnamed tributary to Ellerbe Creek that emerges from a double box culvert under 1-85. It is paralleled by Belleview Avenue to the east. Maintenance of the immediately surrounding golf course, channel straightening, and the large amount of impervious surface in the surrounding urban watershed were primarily responsible for the stream's instability. The golf course had intensively managed the vegetation adjacent to the stream and only a grass buffer existed along the banks. The result was an entrenched stream with low sinuosity. The channel was incised four to six feet and erosion and slumping affected large portions of the banks (Stantec 2005b). • Ellerbe Creek Stream Restoration 2008 Final Monitoring Report Project #127 Year 4 of 5 RJG&A Page 6 • r1 ?J r 1 LJ Ellerbe Creek Stream Restoration Project #127 RJG&A 2008 Final Monitoring Report Year 4 of 5 Page 7 E • • D.

Project Conditions and Monitoring Results RJG&A's initial 2008 qualitative evaluation was conducted in April and the project appeared to be functioning as designed. Subsequent evaluations in July and October 2008 also revealed relatively complete design compliance. A. Vegetation Assessment The average live, planted, woody stem density for all plots was 798 stems per acre or approximately 19 individuals per plot (Appendix A-1, Table 5). This exceeds the required 320 stems per acre in the third monitoring year by 149 percent. The eleven vegetation plots contain a total of 186 volunteer woody stems; resulting in a density of 1,483 stems per acre, when combine with the planted stems. Hillsborough Reach Three vegetation problem areas were observed in the Hillsborough reach during the fourth growing season. All occur on the slopes between the terrace and the golf course and are likely to have resulted from rill and gully erosion in compacted subsoil. All three areas were identified as problem areas in 2006 and 2007, but have decreased in size and move off of the floodplain areas. In addition to these three larger vegetation problem areas, small, isolated rill and gully areas exist throughout the project that have poor vegetative cover, as well (Appendix A.1 and A.2). Although three active beaverdams were located in this reach, no evidence of beaver browsing was observed in this, or any other reach in the project. Croasdaile Reach In the Croasdaile reach, the NCDOT rip-rap spillway crosses the riparian buffer to intersect with the stream , resulting in no vegetation in this area. No remedial action is recommended/possible at this time. Hillandale Reach Two small rill and gully vegetation problem areas were observed in the Hillandale reach. One area on the left-bank slope from the terrace, immediately downstream from cross- section four, and the other on the right-bank slope beginning at station 3880. As described above, this vegetation problem area is likely to be the result of the lack of an adequate substrate and run-off from the golf course. The third problem area in the Hillandale reach involves bare floodplain soils at station 4450 (Vegetation problem Photo 2). Albany Reach Two vegetation problem areas were observed in the Albany Reach. Both are a combination of rill and gully erosion on the slopes and bare soil on the floodplain, due to poor/compacted soil. Vegetation monitoring plots in the vicinity of these areas have 19 Ellerbe Creek Stream Restoration Project #127 RJG&A 2008 Final Monitoring Report Year 4 of 5 Page 10 and 34 live planted stems (769 and 1,376 stems per acre respectively), so no remedial • action is recommended at this time. B. Stream Assessment 1. Morphometric Criteria RJG&A staff evaluated the Ellerbe Creek Stream Restoration site during April, July, and September 2008. The RJG&A staff collected the fourth year of vegetation data during July 2008 and the geomorphic data during September 2008. As the quantitative data and qualitative evaluations indicate, after the fourth growing season the structure and function of the entire restoration project very closely match the as built conditions and nearly all structures appear to be functioning as designed. Since 2006, a structural failure has been monitored at a cross vane on Ellerbe Creek's right bank at station 6330 (Appendix 131.3). The vane's downstream-most header rock has become entirely dislodged from the underlying footer and is in the channel below. From the header's former location, the downstream bank is eroding severely and slumping into the creek for approximately 30 more feet. Several areas of scour, aggradation, and structure undermining were observed at other locations (Table B 1 in Appendix B). A total of three active beaverdams were observed throughout the restoration project, all is of which located in the Hillsborough reach. Those three, along with three additional abandoned dams in this reach, are impounding water and sediments in the uppermost reach. All six are identified in the longitudinal profile (Appendix B). The lowest portion of the Albany reach continues to be impounded, presumably due to downstream beaver activity, resulting in flooded structures and aggregation in the two downstream-most pools. Several slopes with rill and gully erosion are still present throughout the site (Table B1). These will continue to be evaluated. Although construction overflow spillway that serves the I-85 stormwater settling basin has altered a portion of the Croasdaile Reach's right bank and the dimensions of the adjacent constructed wetland, it appears to be stable and functioning. 2. Hydrologic Criteria On 13 June 2007, a crest gauge was installed at station 5818 to document bankfull events. The crest gauge was checked and reset during the spring 08 initial assessment and the fall 08 monitoring. The crest gauge data indicate that at least two bankfull events had occurred as of 18 September 2008 (Table V). Further evidence that a bankfull event has occurred include rack and drift lines and downed vegetation/stems well above the bankfull elevation that were observed on both occasions throughout the restoration. • Ellerbe Creek Stream Restoration 2008 Final Monitoring Report Project #127 Year 4 of 5 RJG&A Page 11 • • NC CRONOS precipitation data indicate that at the National Weather Service COOP station 312515 in Durham County, significant rainfall events occurred on March 4 (2.00"), August 28 (4.82"), September 6 (3.98"), and September 26 (2.18") (NC CRONOS 2009).

Wetland Assessment As part of the project design, a stormwater wetland and 11 pocket wetlands were created throughout the Ellerbe Creek floodplain. No monitoring wells were established in relation to any of these wetlands and EEP did not claim any mitigation credit for them. By all appearances, all of the wetlands appear to be functioning as designed. The NCDOT rip-rap stormwater spillway could negatively impact hydrology in the Croasdaile Reach's constructed wetland. IV. Methodology Methods employed were a combination those specified in the Mitigation Plan, the First Annual Monitoring Report, and standard regulatory guidance and procedures documents. Photographs were taken digitally. A Trimble Geo XT handheld sub-meter GPS unit was used to collect cross section, vegetation corner, photopoint, and problem area locations. A. Stream Methodology Standard fluvial geomorphic techniques were used to collect geomorphic data (Rosgen 1997; USACOE 2003). A South Total Station and Nikon automatic level were used for collecting all geomorphic data. RIVERMorph 3.1 was used to analyze data. A wetted perimeter bed material analysis was performed at each cross section during July 2008. Photographs facing downstream were taken at each cross section. B. Vegetation Methodology Eleven vegetation survey plots were established during the first year of monitoring. Within each plot, the height and live stem diameter were recorded for each stem location. All planted stems were flagged with survey tape. Volunteer woody vegetation was also identified and categorized by height or diameter class. All vegetation was identified using Radford and Weakley (Radford 1968; Weakley 2007). Photos were taken of each vegetation plot from the 0,0 corner. Tables 5 and 6 in Appendix A contain the data from the vegetation monitoring. Monitoring plot photos can also be found in Appendix A. • Ellerbe Creek Stream Restoration 2008 Final Monitoring Report Project #127 Monitoring Year 4 of 5 RJG&A Page 20 References Lee, Michael T., Peet, Robert K., Roberts, Steven D., Wentworth, Thomas R.
