The Municipal Rain Catcher Award was earned for two innovative projects. The South Park Watershed Enhancement Project, located in Charlotte, NC, was earned by the City of Charlotte Stormwater Services and the Northwest Park Project, in Morrisville, NC, was earned by the Town of Morrisville, Mullis Design Group and Ballentine Associates, P.A.
The City of Charlotte Storm Water Services South Park Watershed Enhancement Project was designed to treat and remove pollutants from stormwater runoff to the Little Sugar Creek Watershed by implementing green infrastructure best management practices on a 36-acre public school campus in Charlotte, N.C. The project was comprised of five stormwater control measure (SCM) retrofit projects including two bio retention areas, an infiltration trench and a wet detention pond with a sand filter. The SCM retrofit projects helped improve water quality in the on-site creek, which is impaired for fecal coliform, turbidity and dissolved oxygen. In order to treat an area that is hard to access, an inverted siphon pipe is located under the creek to direct runoff from the area to the wet pond. In addition, the SCM retrofit projects are located in areas with permanent easements which facilitate long-term access for maintenance.
