Join OC Parks, Newport Bay Conservancy and volunteers around the world for Coastal Cleanup Day at Upper Newport Bay on Saturday, September 20! Lend a helping hand and make a positive impact on our coastlines as we work together to remove trash and recyclables from the marsh, waterway and beaches.

Every September, families, friends, co-workers, schools and scouts from across Orange County come together to volunteer their time cleaning up Upper Newport Bay. This year’s goal is to remove more than 10,000 pounds of trash, as waste items can harm wildlife, pollute waterways and impact public health.

Volunteers will meet at various cleanup sites around the 11-mile loop of the bay. Exact meeting locations will be announced prior to September 20.

Participants are encouraged to wear old clothes, closed-toe shoes (tall/rubber boots are best) and bring a refillable water bottle, gloves and a trash bag or bucket. A commemorative t-shirt will be given to all volunteers.
