Design Spec: Infiltration Practices, 2013

Developed by the Virginia Department of Conservation and Recreation, this design specification (Version 2.0, 2013) provides guidance on using infiltration practices to reduce stormwater runoff by temporarily storing water and allowing it to exfiltrate into underlying soils. It helps designers evaluate site suitability, select appropriate infiltration systems, and size practices to maximize runoff reduction while protecting groundwater quality and ensuring proper drainage performance.
