Over four tons of trash and debris were collected by the volunteers and City crews from the Public Works Department and the Department of Water & Power. The most common items retrieved were plastic bags, food wrappers and containers, used tires and tarps. This event has a direct, positive impact on local watersheds, such as the Prado Basin and the Santa Ana Watershed, and native wildlife. Not only are local areas improved, since these waterways flow to our beaches and coastal waters, everyone downstream benefits too.
