oriented improvements to maximize environmental benefits while working within Site constraints, technical guidelines, and availability of funds These goals were accomplished by the following I Creating a floodplain bench including off -line wetlands to reduce the amount of sediment entering the stream by acting as a repository for soils suspended in the water column during high flow events, providing water storage to further allow sediment to settle out, and slow recharge of stormwater into the groundwater subsurface network 2 Enhancing vegetation to provide habitat/food sources, shade the stream, filter overland runoff, and remove soil particles and other nutrients from stormwater 3 Protecting a Site identified in a watershed that is listed as impaired for elevated levels of fecal coliform bacteria and turbidity (NCEEP 2007) The Site is located on the western side of the City of Charlotte, approximately 2 miles southeast of the Charlotte Douglas International Airport, in Mecklenburg County The Site is located in United States Geological Survey Hydrologic Unit 03050103020020 (North Carolina Division of Water Quality [NCDWQ] Subbasm 03- 08 -34) of the Catawba River Basin and will service USGS 8 -digit Cataloging Unit (CU) 03050103 The Site is located in an EEP Targeted Local Watershed within the Sugar Creek watershed, this watershed in conjunction with the Little Sugar, McMullen, and McAlpine Creek watersheds in CU 03050103 drain point and nonpoint sources of pollution from the metropolitan center of Charlottle severely impacting aquatic health of the watershed The waters are listed as impaired for elevated levels of fecal coliform bacteria and turbidity, the main goal in this CU is to provide better stormwater management (NCEEP 2007) Prior to construction, the Site was located within a FEMA buyout area where several homes were demolished and removed Surrounding land uses include commercial and residential areas with narrow riparian corridors adjacent to streams, greater than 85 -90 percent of the contributing watershed having been cleared and developed This project was constructed between the spring and early winter of 2009 The project consisted of enhancement (level II) of 980 linear feet of stream by laying back stream banks, excavating an extensive 90- to 100 -foot wide floodplain bench along the entire project stream length, creating 0 5 acres of wetlands within the floodplain bench, and planting with native forest species Several structures were left at the downstream end of the Site rather than removing them to avoid disturbance to the wetland area and stream banks In addition, it was verified by HDR Engineering that the structures will not cause an issues Irwin Creek (Final) Axiom Environmental, Inc.
