Operations Center Rain Garden

A rain garden is a depression in the landscape that collects rain water from a hard surface such as a roof, driveway or street and allows it to soak into the ground. Planted with native shrubs, sedges and flowering perennials, rain gardens help filter out pollutants in runoff. They can be a cost effective and beautiful way to reduce runoff while providing food and shelter for native animals.

Clark Public Utilities’ Operation Center rain garden is a demonstration site, designed and installed by employees, which uses a natural bioswale to capture and treat all roof water runoff in an environmentally friendly way. The lush landscape provides additional education opportunities for visitors and school tour groups and a natural habitat for native wildlife.
