Green infrastructure encompass a wide array of practices, including stormwater management. Water management using green infrastructure practices mimics the natural water cycle. Examples of green infrastructure practices include planting trees, restoring wetlands, enhancing biodiversity, and restoring floodplains. Green infrastructure incorporates both the natural environment and engineered systems to provide clean water, conserve ecosystem values and functions, and provide a wide array of benefits to people and wildlife. Green infrastructure can be applied on different scales, from the house or building level, to the broader landscape level. On the local level, green infrastructure practices include rain gardens, permeable pavements, green roofs, infiltration planters, trees and tree boxes, and rainwater harvesting systems. At the largest scale, the preservation and restoration of natural landscapes (such as forests, floodplains and wetlands) are critical components of green infrastructure.

Stormwater management using green infrastructure practices involves keeping and using water close to its point of origin (i.e. keeping the raindrop where it falls). Practices include those local practices mentioned above - rain gardens, permeable pavements, green roofs, infiltration planters, trees and tree boxes, and rainwater harvesting systems. Because there multiple benefits of these practices, in addition to stormwater management, the manual includes a variety of topics related to green infrastructure as illustrated below.

Green Infrastructure: Throughout this manual, these green alert boxes identify a stormwater practice that is considered a green infrastructure practice.
