The Earth Day clean-up event is an annual event hosted by the Alameda County Clean Water Program, that helps keep our waterways free of harmful trash. This year, we need your help to clean Castro Valley Creek, San Lorenzo Creek, and other community waterways by cleaning up in your neighborhoods and local natural areas. Please participate and help us get the word out. These annual clean up events are so important to the waterways!
