Since 1999, CVSan has been coordinating April Earth Day events for Castro Valley.  From the early days of the Festival and 5K Fun Run to the Clean-Up and Recycles Day mainstay that we have now, it’s been our pleasure to serve Castro Valley each year by orchestrating this community environmental effort.

While Earth Day is every day at CVSan, our Earth Day Clean-Up and Recycles Day event means something more. It means organizing breakfast, tools, mulch, compost, and other materials for 500 to 1,000 volunteers for the event.  Earth Day means involving most schools and many, many families, parents, students, and school staff all chipping in to beautify their schools and parks.  It means continuing the CVSan Mission to protect public health and the environment for Castro Valley and our planet.


What Kinds of Projects are Completed on Earth Day?

Earth Day clean-Up projects can range from anything related to gardening such as spreading mulch (an annual favorite), working in new compost, planting bay-friendly native plants, painting, and more. We’ve also had litter pickups, creek restorations, and other beautification efforts. It’s really up to you and your group since we can assist with a wide variety of projects.


Who Participates in CVSan’s Earth Day Clean-Up?

Each year we work with local schools, parks districts, business groups, and community members to clean up and beautify Castro Valley. Volunteers of all ages are welcome, and no group is too small to come out and help for a few hours to beautify Castro Valley!


Are You Interested in Coordinating a Group or Project?

A Successful 2017 Earth Day Clean-Up & Recycles Day Event!

Earth Day Clean-Up

The weather was perfect once again for the CVSan’s Earth Day Clean-Up event on Saturday, April 29, 2017.

Over 500 volunteers at twelve Castro Valley schools and five public sites participated in the 15th annual Clean-Up.  Volunteers cleared 50 cubic yards of plant debris to be composted and abated one cubic yard of litter from Castro Valley streets, parks, schools, and creeks.  Volunteers enjoyed free breakfast provided by CVSan, Alameda County Supervisor Nate Miley, and Karin Johnson Specialty Cakes and Pastries.  Other event sponsors included Pete’s ACE Hardware, Hayward Area Recreation and Park District, East Bay Regional Park District, Alameda County Public Works Agency, and Waste Management of Alameda County, Inc.
