The Dell at the University of Virginia Emmett Street • Charlottesville, Virginia

The basic stormwater management concept at The Dell is capture, cleanse, convey, reuse in water feature, detain and discharge.  Runoff sheeting into the daylighted Meadow Creek is first cleansed and partially infiltrated to ensure the creek is as clean as possible; the meandering creek is subsequently channeled and drops into a 2-cell wet detention pond: water drops sediment in the forebay, then overflows into the second detention cell.  The detained water later discharges to the storm sewer at a controlled rate that doesn’t overtax the grey infrastructure.  According to UVa and state monitoring, the project meets or exceeds all water quality and quantity goals, significantly reducing and delaying peak stormwater discharge and reducing sediments and nutrient loading downstream.
