A raingarden is an artificial depression in the landscape that collects and stores stormwater runoff until it can infiltrate the soil. Stormwater runoff increases urban flooding and erodes the banks of rivers and streams. Urban runoff also carries many pollutants into streams and rivers.
A raingarden is an approach to rainwater harvesting that can prevent flooding and erosion and turn stormwater problems into water supply assets by slowing run-off and allowing it to soak into the ground. Raingardens are not ponds. They are usually planted with native vegetation that is hardy and attractive. Plants in a raingarden can give color to the landscape at all times of the year.
Raingardens can be designed for an individual yard or a neighborhood. They provide a habitat for many animals including birds, butterflies and other insects.
