Glossary terms are italicized on first mention in the text. For a comprehensive list, see Virginia Cooperative Extension (VCE) publication 426-119, “Urban Stormwater: Terms and Definitions.”

Infiltration practices provide temporary surface and/or
subsurface storage, allowing infiltration of runoff into
soils. In practice, an excavated trench is usually filled
with gravel or stone media, where runoff is stored in
pore spaces or voids between the stones (see figure
1). These systems can reduce significant quantities of
stormwater by enhancing infiltration, as well as provide
filtering and adsorption of pollutants within the
stone media and soils. Infiltration practices are part of
a group of stormwater treatment practices, also known
as best management practices (BMPs)
