The Community Identifier Projects are in three locations: Castro Valley, Ashland/Cherryland, and San Lorenzo. The overall goal of the projects is to create community gateway markers that help support a positive and welcoming environment for both the community and visitors. These projects are managed by the Alameda County Arts Commission in partnership with the community and many project partners.

Artist Robert Minervini painted the Castro Valley Community Identifier Project on both sides of the I-580 Highway overpass above Redwood Road. Robert Minervini’s design features the words “Castro Valley” in bright golden yellow letters along with a colorful panoramic landscape that features Lake Chabot and the Bay.
