Castro Valley Sanitary District

21040 Marshall Street, Castro Valley

Gardening experience: Total 1 year at this location.

Garden size: one acre, 86% native

Showcase feature: In the spring of 2006, a drab, high-maintenance garden containing hedges, roses, and a thirsty lawn (which consumed 24,000 gallons of water a year!) was removed and replaced with native and Mediterranean plants by Michael Thilgen of Four Dimensions Landscape Development. Thirty-six species of natives—twenty-three of them locally native—have been incorporated into this small garden. The renovated landscape, which has reduced maintenance and water costs, is maintained by students with disabilities, in a program run through the Castro Valley Adult School.


Other garden attractions:

Gardening for wildlife: There are no pest problems here! Insects are considered valuable additions to the landscape, and a visible sign of a healthy ecosystem.
