Save the Bay™, and keep it saved, as defined by reaching a 70 on CBF's Health Index. The Chesapeake Bay Foundation's (CBF) mission, simply stated, is to Save the Bay and keep it saved. We define a Saved Bay as having a score of 70 (out of 100) on CBF's State of the Bay health index. Thanks largely to a dramatic reduction in the amount of pollution entering the system, at 70, the Chesapeake Bay and its tributary rivers will be highly productive and in good health as measured by established water-quality standards. The result will be clear water, free of impacts from toxic contaminants, and healthy oxygen levels, able to support living resources in all parts of the Bay.

The Los Angeles River is the birthplace of our region and was once the thriving, unifying water source for the people and wildlife of Los Angeles. But that connection and our collective history was severed when the River was encased in concrete and fenced in 1938. In an act of civil disobedience, poet activist Lewis MacAdams took the first steps to repair that severed connection in 1986 when he cut a hole in the chain link fence that obstructed Angelenos from their rightful River. He declared the River open to the people and swore to serve as its voice. And so, Friends of the Los Angeles River (FoLAR) and the River Movement were born. FoLAR has endeavored for over 30 years to restore community connection and natural ecology as the single largest unifying force on the River – educating, empowering, and mobilizing over 70,000 Angelenos to repair habitat and fight for the policies that will reclaim our collective right to a healthy, thriving, and equitably accessible Los Angeles River. Our mission is to build capacity for communities, students, and future leaders to advocate for nature, climate, and equity on the Los Angeles River.
