Join Sycamore Grove Park Rangers and Living Arroyos  for the annual California Coastal Cleanup Day! Volunteers will be cleaning up sites along Arroyo Mocho at Robertson Park.

 California Coastal Cleanup Day is the country’s largest annual volunteer event. Each September, volunteers remove hundreds of thousands of pounds of trash from the state’s beaches, lakes, and wateways. Living Arroyos will be hosting trash cleanups at multiple sites across the Tri-Valley.
