• Address illicit sewage discharge • Plant riparian buffers where veg is thin. • Bioswales! • Disconnect man-made ditches that direct runoff to the creek • Construct a bioretention or wetland near North Cary Park
Suggested projects Town of Cary response Address illicit sewage discharge 2,900 ft. of sewer and 50 manholes along Black Creek sewer system rehabbed in 2014 Plant riparian buffers where veg is Agree thin Bioswales to manage stormwater Town standards require grassed swales on high side of greenway to collect runoff, drained to culvert crossings under trail Disconnect man-made ditches that Culverts will end in riprap pads or direct runoff to the creek plunge pools to disperse- sheet flow as possible Construct a bioretention or wetland Looking to incorporate wetland near near North Cary Park N.
