Green Infrastructure (GI) - Curb Cuts

Curb cuts are used in parking lots or streets to allow rainwater to flow into the adjacent landscape. Tree planters or bio-swales are used in combination with the curb cuts and, natural, low-water use plants can be in the landscaped area. When it rains, the runoff enters the landscaped area to water the plants and filter into the ground. This takes pressure off of the storm sewer system, reduces flooding, and filters pollutants from parking lots and streets.

Examples of Curb Cuts

Here are pictures of curb cuts in the city of Phoenix that help conserve water. By allowing water to filter into the ground these bio-swales capture sediment and make use of runoff, while protecting the storm sewer system.
