The project is located within the eastern portion of HUC 03050101170020, the Long Creek watershed, which is listed as a Targeted Local Watershed (TLW) in the 2007 Catawba River Basin Restoration Priorities (RBRP) plan (amended in 2013 as the Lower Catawba RBRP). The project is also located in the Charlotte Local Watershed Plan (LWP). Currently, this is the only DMS project in this TLW. There are a total of 16 DMS projects in the LWP. McIntyre Creek drains to Long Creek approximately three miles downstream of the project site. Following the publication of the 2007 RBRP, Long Creek was identified on the 2008 NC Division of Water Resources (DWR) 303d Impaired Waters list as exceeding criteria for turbidity and copper. Long Creek is also classified as a Water Supply Watershed (WSW) by the DWR. The 2003 Charlotte LWP identifies the eastern portion of the Long Creek Watershed along the I-77 corridor for its dramatic population increases from 1990 to 2000. The Long Creek Watershed also contains 3 of 6 focus areas evaluated in the Charlotte LWP (Belmeade Drive, Lawing School, and Long at I-77). The 2007 RBRP states that lands in the eastern portion of the Long Creek Watershed are 47% developed, with 42% of streams lacking adequately forested buffers. Goals from the 2007 RBRP include: (1) improve management of stormwater runoff and help restore biology in the watersheds; and (2) protection of the critical water supply reservoirs in the region and their immediate riparian zones The goals of the McIntyre Creek at Hornet's Nest project are consistent with DMS watershed planning goals. The project restores riparian buffers which increase roughness and mitigates the effects of stormwater runoff, reduces erosion by stabilizing and vegetating the streambanks, improves aquatic habitat, and protects waters draining to a WSW through restored riparian buffers and conservation easements. Proiect Setting and Background Summary The McIntyre Creek Stream Restoration Site is located Catawba River Basin 03050101170020. Prior to construction, the Site contained a degraded stream channel with a disturbed riparian buffer located within Hornets Nest Park. Site streams were characterized by eroding banks, channel widening, high sediment inputs from construction occurring in the upstream watershed and onsite bank erosion, and channel incision as indicated by bank -height -ratios ranging from 1.4 to 1.9. Surrounding land uses include commercial and residential areas with narrow riparian corridors adjacent to streams. At least 50 percent of the contributing watershed had been cleared and developed. McIntyre Creek is a pre-2003 project that was instituted on April 16, 2002. The project mitigation plan (restoration plan) was completed in December 2002, and site construction was completed in May 2008. As constructed, the project restored 5178 linear feet of stream using Priority I restoration by constructing a new meandering channel within the McIntyre Creek floodplain, incorporating in -stream structures, installing grade control structures at the confluence with two tributaries to McIntyre Creek, and planting with native forest species. Site activities provide 5129 Stream Mitigation Units (49 linear feet of the restored channel is located within a utility easement and therefore was not included in the available mitigation credit). Planting occurred within 10.75 acres of the 17-acre conservation easement including stream banks, floodplain, and wetlands. Repair efforts to reestablish structures, stabilize banks, provide grade control, and dissipate stormwater energy was completed in January 2010. During years 1 (2010) through 5 (2014), bank erosion was in scattered areas across the site, with those at the bottom of the project (Monitoring Reach 1) being the most concerning in that they represented active mass wasting. As a result, DMS repaired Monitoring Reach 1 early in 2016. The areas in Monitoring Reaches 2 and 3 were less concerning in that they are dominated by surficial scour (8 and 5%, respectively) as opposed to mass wasting. Additionally, these features developed earlier in the project and have not advanced in recent years. The bank erosion percentages within these reaches have either remained the same or improved slightly compared to prior years. Erosion was also observed in pool cross -sections 1 and 4 earlier in the projects history; however, these cross -sections have not demonstrated any appreciable change even when exposed to multiple storm flows. The watershed is extremely flashy due to the extensive amount of impervious surface in the contributing watershed and floods quickly even during modest rain events. Therefore, the repairs focused on the bottom reach (Monitoring Reach 1) thereby avoiding unnecessary disturbance of sections that appear to have equilibrated. Repair activities included bank grading, installing geo-lifts and repairing structures. The repair has successfully stabilized the areas of concern throughout 1.5 growing seasons and has withstood several bankfull events. Since five years of monitoring data was collected prior to the repair in 2016, a modified monitoring schedule was developed. The ten vegetation monitoring plots had an average density of 477 planted stems per acre surviving in year 5 (2014); therefore, the site has met the vegetation success criteria. Five years of profile data did not indicate any significant areas of aggradation or degradation of the stream channel, so profile survey was discontinued. After the repair, four temporary vegetation plots were established along Monitoring Reach 1 to assess the areas requiring supplemental planting and three additional cross sections were installed. Monitoring for year 6 and 7 consisted of the four temporary vegetation plots, four permanent and 3 additional cross sections, photo points and visual assessment. Two groundwater gauges were installed within the site in wetland areas created because of stream restoration activities. An additional gauge was placed just outside of delineated wetland. DMS is not seeking any wetland credit; however, there are approximately 1.71 acres of wetland creation at the site. Vegetation areas of concern at the site consist of multiflora rose, Chinese privet, Japanese honeysuckle and kudzu. The site has received multiple invasive treatments throughout the project history. A treatment of all invasive species occurred in late October 2013 and again in early 2014. Additional treatments occurred again in October and December of 2015 and September 2016. DMS is working with City of Charlotte to treat kudzu outside the easement on park property. Beaver activity has been evident throughout a majority of the monitoring years. Sixteen dams were removed in 2013, eight dams in 2014, and one dam in 2016. USDA -APHIS is continuing to monitor the site for beaver and beaver dam removal through project closeout in 2017. Goals and Obiectives 1. Restoring stable channel morphology capable of moving flows and sediments provided by the watershed. 2. Improving water quality by reducing soil and riparian vegetation loss resulting from lateral erosion and bed degradation. 3. Improving aquatic habitat with bed variability and the use of in -stream structures. 4. Stabilizing tributaries draining into McIntyre Creek. 5. Providing educational opportunities through Mecklenburg County. 6. Improving the natural aesthetics of Hornets Nest Park. 7. Enhancing vegetation to provide habitat/food sources, shade the stream, filter overland runoff, and remove soil particles and other nutrients from stormwater. 8. Protecting a Site identified in a watershed listed as impaired for elevated levels of copper and turbidity (NCDWQ 2010).

During years 1 (2010) through 5 (2014), bank erosion was scattered across the site, with those at the bottom of the project (Monitoring Reach 1) being the most concerning in that they represented active mass wasting. As a result, DMS repaired these areas in Monitoring Reach 1 early in 2016. The areas in Monitoring Reaches 2 and 3 were less concerning in that they are dominated by surficial scour as opposed to mass wasting. Bank erosion within these reaches has either remained the same or improved slightly compared to prior years. The watershed is extremely flashy due to the extensive amount of impervious surface in the contributing watershed and floods quickly even during modest rain events. Therefore, given the lack of change within the last 3 years, the repairs focused on the bottom reach (Monitoring Reach 1) thereby avoiding unnecessary disturbance of sections that appear to have equilibrated. The repair has remained stable for 1.5 growing seasons. Based on the number of stems counted, average densities were measured at 477 planted stems per acre (excluding livestakes) surviving in year 5 (2014); therefore, the site has met its vegetation success criteria. Four temporary vegetation plots were established along Monitoring Reach 1 to assess the areas requiring supplemental planting after the repair. Counts and speciation of all stems within these plots was performed. Year 7 (2016) results indicate an average of 1427 stems per acre with 4 to 6 species per plot, including natural recruits, within this reach. Vegetation areas of concern within the Site include several patches of multiflora rose (Rosa multijora), Chinese privet (Ligustrum sinense), Japanese honeysuckle (Lonicera japonica), and kudzu (Pueraria lobata). Invasive species treatments occurred in late October 2013, early 2014, October 2015, December 2015, and September 2016. The most recent treatments appear to be successful with significantly less invasive species populations observed during year 7 (2016) than previous monitoring years. Beaver activity observed on the Site during previous monitoring years has lessened due to proactive measurements taken by DMS. Some signs of recent beaver activity were observed throughout the Site during monitoring year 7 (2016), however, no dams were observed during monitoring activities. Beaver activity is controlled as much as possible, and evidence of beaver activity should not be seen as a threat to Site success. In addition, 19 bankfull events were documented throughout the course of the monitoring period with at least one event occurring in each monitoring years. Contingencies None. 'ir .. - k .
