Creek Cleanups

Trash can travel through storm drains, creeks, and rivers to become bay pollution.

How Can We Help?

Litter hurts our waterways and wildlife. Let’s work together to clean up our creeks, parks, and neighborhoods. You can participate by hosting your own cleanup site, or attending a cleanup hosted by the City! Cleanups are hosted every year in May and September for National River Cleanup Day and Coastal Cleanup Day, respectively.

Join the City of Milpitas at Berryessa Creek (near Los Coches St and S Hillview Dr) on Saturday, September 20 from 9:00 am to 12:00 pm to keep our waterways clean!
