September is Coastal Cleanup Month. Join in!

Coastal Cleanup Day 2021 Poppy Poster

This year, Coastal Cleanup Day is September 18th, 2021, and several Alameda County cities are bringing back in-person cleanup events! In addition, you can also organize your own cleanup any time in September.

No matter where litter happens, it flows downstream to the coast and becomes ocean pollution. If everyone cleaned up a small area near where they live, it would make a big difference. When you protect your own favorite “happy place” you get a prettier place to live AND protect ocean wildlife too! 

Last year during Coastal Cleanup Month (September 2020), over 10,000 Californians participated in more than 3,000 self-guided cleanups across the state, gathering close to 70,000 pounds of trash from neighborhoods, local parks, creeks, or other natural spaces to which they had safe and easy access.

Do Your Own Self-Guided Cleanup

Choose a day (or several!) in September and go out by yourself, with your family or a small group of friends and protect your happy place by picking up litter! Local parks, shores, creeks, streets, sidewalks, drainage areas, natural areas, and trails are all good choices. The Coastal Commission offers the free, CleanSwell app to track the litter you pick up and report your efforts. That way your work will be counted in statewide results!

Step 1

Step 2
