Design Spec
Design Spec: Rooftop Disconnection, 2013
Developed by the Virginia Department of Conservation and Recreation, this design specification (updated 2013) provides guidance on disconnecting rooftop runoff to reduce stormwater at its source through infiltration, filtration, and reuse practices. It helps designers select and size appropriate approaches—from simple downspout disconnection to integrated practices like rain gardens and cisterns—to improve runoff reduction performance.
