Coastal Cleanup Day at Castro Valley Creek Trail

September 18, 2021 @ 9:00 am - 12:00 pm

| Free

Join the Clean Water Volunteers for Coastal Cleanup Day at the Castro Valley Creek Trail! Earn Service Hours!

Be part of the 37th annual Coastal Cleanup Day at the Castro Valley Creek Trail! Volunteers* will participate in a litter pickup along the creek trail and beautify the trail starting from the Castro Valley Library to Castro Valley Creek Blvd.

Trash from inland areas, like Castro Valley Creek, flows downstream to the coast and into the ocean. Cleaning upstream riparian areas helps prevent garbage from entering the ocean, protecting birds and other marine animals, while beautifying the environment. Yeah!

Volunteers* may also participate in a water testing demonstration to learn about various types of water pollution and their effects on the creek and the ocean.

This effort is part of the statewide Coastal Cleanup Day and is made possible by the Alameda County Flood Control and Water Conservation Districts. To contribute to the statewide litter count, download the Clean Swell App before you arrive and have your trash be part of the California count!
