Twenty years ago, people who saw a need to help people conserve water and preserve San Diego’s environment conceived the idea for a demonstration garden.

The Water Conservation Garden celebrates its 20th-anniversary Saturday, November 16 at 5 p.m. with a benefit concert featuring food and drink stations, dancing, auction items and live music provided by The Mighty Untouchables. More information and tickets are available on The Garden’s website.

Native San Diegan Jon Foreman of the Grammy-award winning band Switchfoot is among The Garden’s newest fans after a recent visit.
