Best Management Practices that infiltrate stormwater runoff into underlying soil include, but are not limited, to
- infiltration basins,
- infiltration trenches,
- underground infiltration,
- bioinfiltration,
- permeable pavements, and
- tree trenches and tree boxes.
These are discussed briefly below.

An infiltration basin is a natural or constructed impoundment that captures, temporarily stores, and infiltrates a design volume of water.
