The Great Los Angeles River CleanUp! is the nation's largest urban river CleanUp drawing more than 9,000 volunteers to fourteen sites over three weekends in April. Our last weekend, April 29, is along the lower portion of the river, in Long Beach! This year's CleanUp is especially important because with all the rain, we have more debris and trash in the river. We need volunteers to join us on April 29 to help clean our river and improve our community. Community service hours for all students who attend!
