Rain gardens are shallow depressions in the landscape designed to capture, filter, and absorb rainwater. Rain gardens slow the flow of rainwater from roofs, sidewalks, streets, parking lots, and other impervious surfaces, allowing the water to penetrate the soil. They are often planted with colorful native plants and grasses and serve as habitats for wildlife such as birds and butterflies. When designed properly, water in the rain garden should stand for no more than 24 to 48 hours.

CONSERVES WATER

Reduces the need for supplemental irrigation (plants also prefer rainwater over municipal water)

PROTECTS WATER QUALITY

Plants help filter pollutants like roofing tile chemicals, fertilizer, and litter from the sidewalk

HELPS REDUCE FLOODING AND EROSION

Runoff collects in the low area and soaks into the soil instead of rapidly washing into creeks and washes

HELPS RESTORE GROUNDWATER

Deep rainwater infiltration aids in the regeneration of groundwater levels that have been depleted as a result of over-pumping.
