Welcome to California Coastal Cleanup MONTH! This year, California Coastal Cleanup begins at everyone’s front doors. Tens of thousands of Californians will help keep our beaches and waterways free of debris by cleaning within their own neighborhoods while staying safe and maintaining distance from others outside their households. Trash travels through storm drains, creeks, and rivers to become beach and ocean pollution, so Californians can make a real difference to the health of the coast by removing trash before it has a chance to become marine debris.
