Version B Project Information and Prior Project History 3 Project Description 3a Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application The project is located within the Cox Mill Elementary School Complex which also serves as the communities soccer and baseball fields Currently the project site discharges untreated stormwater from an approximate 64 acre school and recreation complex into a large riparian wetland system (Clarke Creek Heron Rookery designated as a NC Significant Natural Heritage Site) Clarke Creek is classified for secondary recreation and has been listed as an impaired water in the 2008 Yadkin Pee Dee River Basin Plan for habitat degradation and low dissolved oxygen from stormwater runoff Clarke Creek discharges into Rocky River just southeast of Cox Mill Road in Cabarrus County Rocky River is listed on the 303(d) list and is designated by North Carolina Department of Water Quality as an impaired stream for turbidity and fecal coliform Rocky River is also listed as an Urban 303 (d) Stream In addition Clarke Creek was listed on the 2010 303(d) list for the poor bioclassification of aquatic life for ecological and biological fish community integrity 3b List the total estimated acreage of all existing wetlands on the property 1255 3c List the total estimated linear feet of all existing streams (intermittent and perennial) on the property 00 3d Explain the purpose of the proposed project In October 2010 the NC Clean Water Management Trust Fund (CWMTF) awarded CSWCD a grant to implement a series of five low impact development stormwater best management practices throughout the Cox Mill Elementary School Campus to treat water quality from stormwater volumes (1 t 1 inch flush) The implementation of this project will improve infiltration rates reduce peak stormwater flows provide educational initiatives facditiate research and improve the water quality and aquatic habitats within the Clarke Creek Watershed by reducing nutrient and sediment loads to the system In addition the project will implement a 26 65 acre conservation easement within the 100 yr floodplam and approximately 3 12 acres of stormwater easement for the BMPs The proposed BMPs include two (2) bioretention cells one enhanced grass swale one grass swale and one constructed wetland Page 4 of 15 PCN Form — November 2008 Version B Project Information and Prior Project History 3e Describe the overall project in detail including the type of equipment to be used The Cox Mill Campus property extends from Cox Mill Rd to the centerline of Clarke Creek The drainage area to the proposed project area consists entirely of the Cox Mill Campus to the centerline of Cox Mill Rd The drainage area discharges predominantly from east to west and is divided into 3 main drainage areas The Cox Mill Campus was built in 2002 and the recreational complex which lies within the 100 yr FEMA regulated floodplain is located at the western side of the campus and was built in 2008 Currently there is an existing stormdrainage system located throughout the site however excessive erosion flooding sedimentation and drainage system failures are common throughout the site This proposed project will retro fit the existing site through the implementation of a series of BMPs that will treat urban stormwater run off by regrading swales redirecting stormwater flows increasing run off infiltration adding stormdrainage infrastructure and tying into the existing stormwater drainage system to include the entire drainage area Drainage from the northern end of the site will capture run off into a new stormdrainage system that will tie into the existing system and discharge into a constructed wetland (Site 8) that is to be implemented on the western side of the project area adjacent to a large existing wetland system Drainage from the center of the project site will be captured in two separate drainage divides The majority of the drainage on the eastern side of the campus is currently captured within the existing stormdrainage system Additional areas within this drainage divide will be incorporated and included into the existing stormdrainage system and rerouted to discharge into Site 8 The remaining drainage consists mostly of a parking lot and concession area located in the center of the recreational complex and four of the main sports fields Run off from the parking lot and part of the concession area drain to the north and southwestern sides of the parking lot and will be captured by two bioretention areas (Site 6 & Site 7) Stormwater overflows from Site 6 & 7 will be discharged into a regraded swale and an existing stormdrain system that will ultimately discharge into Site 8 Site 7 has been designed to treat the entire 1st flush of storwater from its drainage area however Site 6 was purposely undersize by 30% in order to provide a post construction cost/benefit analysis for water quality reductions in urban areas whey space is limited for BMP implementation The remainder of the drainage from the four centrally located sports fields will also drain into the regraded swale and /or the existing stormdrain system that too will ultimately discharge to Site 8 Approximately three quarters of the southern part of the site drains into an existing rip rap channel that discharges directly into the adjacent wetland system The southwestern side of the rip rap channel will be replaced by a pair of grass swales (Site 5) one of which will be enhanced by upfitting the centerline of the swale with a underdram pipe and mixed media amendments A level spreader will be installed at the head of each swale to spread out the flow evenly between the two swales (Post construction cost/benefit comparison between the two swales for water quality reductions will also be studied for Site 5 ) A level spreader and outlet protection will be implemented at the tail of the swales before discharging the treated stormwater into the wetland area Site 8 is a constructed wetland and has been designed to capture and treat the entire 1s` flush of stormwater runoff from its receiving drainage areas before discharging into the adjacent wetland system The constructed wetland is located within the FEMA regulated floodway of Clarke Creek and will be constructed by excavating the floodplain and grading the wetland slopes to finished grade Stormwater discharges will enter Site 8 in three locations and flow through the constructed wetland area before discharging into the existing natural wetland system through a nser /outfall structure centrally located on the western side of the constructed wetland dam A rip rap apron will be installed below the pipe outfall No permanent wetland impacts will occur to implement Site 8 however minor temporary impacts will occur to access the area and construct the wetland dam on the western side of the constructed wetland Equipment to be used for excavation installation and grading of the project site are a trackhoe and a dump truck Some of the excavated material will be used to finish the grade of the constructed wetlands earthen dam as depicted in the design plans The remainder of the excavated material will be hauled off site See the plan set and associated project maps for for additional information The wetland will be constructed in the dry with the use of a dewatermg system to minimize impacts After construction of the Site 8 is complete and stabilized the existing natural wetland area will be regraded stabilized and replanted with native wetland vegetation Mud mats will be used when accessing the wetland area to minimize impacts Site 8 will be constructed first so as to act as sediment and erosion control BMP for the remainder of the site All work for this project will follow and comply with the NC Erosion and Sediment Control Planning and Design Manual Page 5 of 15 PCN

the Endangered Species Act of 1973 as amended (16 U S C 1531 1543) (Act) According to our records and a review of the information you provided no federally listed endangered or threatened species or their habitats occur in the project area Therefore we believe the requirements under section 7 of the Act are fulfilled However obligations under section 7 of the Act must be reconsidered if (1) new information reveals impacts of this identified action that may affect listed species or critical habitat in a manner not previously considered (2) this action is subsequently modified in a manner that was not considered in this review or (3) a new species is listed or critical habitat is determined that may be affected by the identified action Thank you for allowing us to comment on this project If
