Green infrastructure uses natural hydrologic features to help manage stormwater. It also provides other environmental and community benefits. Some green infrastructure features are highlighted below.

green landscaping

Rainwater harvesting is used along with water-efficient landscaping and irrigation systems at the Texas A&M Agrilife Extension Service, Dallas, Texas. Rainwater harvesting allows water to be captured from roofs or other surfaces during a rain event, storing it for later non-potable use.  Storage of rainwater can be scaled from a large system (seen here) to smaller rain barrels.

green lot

The parking lot at the Perot Museum of Nature and Science near Downtown Dallas is bordered by a planted bioswale to capture runoff water from the parking lot for the cistern system. Bioswales are vegetated, mulched, or xeriscaped channels that provide treatment and retention as they move stormwater from one place to another. Vegetated swales are particularly suitable along streets and parking lots.

permeable pavement

Permeable interlocking concrete pavement (PICP) at the Texas A&M Agrilife Extension Service, Dallas, Texas. The layer of concrete pavers is separated by joints filled with small stones. Water enters joints between solid concrete pavers. The stones in the joints provide 100% surface permeability and the base filters stormwater and reduces pollutants.

green planting

A rain garden located on the grounds of the Texas A&M Agrilife Extension Service, Dallas, Texas. Also known as bioretention areas, rain gardens are landscaping features adapted to provide onsite treatment of stormwater runoff. Surface runoff is directed into shallow, landscaped depressions designed to incorporate many of the pollutant removal mechanisms that operate in forested ecosystems.
