3. Los Angeles river Clean-up (2nd Saturday of June)
The Los Angeles River has played a crucial part in making Los Angeles one of America's Signature cities. In the past, people often came to the river for recreation and even to drink its water. However, the Los Angeles River has been polluted and has all but been abandoned. PAVA has taken charge to help clean the Los Angeles River for the past eight years, and approximately four to five thousand of Los Angeles' citizens have shown up to each of these annual Clean-Ups to take up responsibility through their actions.
