Earth Day

Since 1999, Castro Valley Sanitary District (CVSan) has been coordinating April Earth Day events for Castro Valley. From the early days of the Festival and 5K Fun Run to the more recent Earth Day Clean-Up and Recycles Day, it has been our pleasure to serve the community each year with these events to support the environment.

The Earth Day Clean-Up and Recycles Day event has brought together 500 to 1,000 community volunteers every year to help with projects all around Castro Valley. Many Castro Valley schools also join the effort with staff, students, and family. Volunteers work together to beautify school campuses and clean up and enhance Castro Valley’s beautiful parks. Earth Day events puts into practice CVSan’s Vision to practice environmental stewardship and to protect our resources.

We Need Trees to Glean From
Do you have a fruit tree that needs to be gleaned and harvested? Sign ups are coming soon and you can email for questions about how it works. We had an abundance of volunteers and shortage of trees during Zero Waste Week 2021 in early February so we’re going to need all the fruit trees we can find for the upcoming Earth Day!
