California Coastkeeper Alliance was founded in 1999 with the belief that clean and healthy water, oceans, and coasts are vital to California’s economy, public health and way of life. Using law, policy, science, and creative media, California Coastkeeper Alliance advances statewide policies and programs for healthy and clean waters.

Along with California Waterkeeper organizations, we are members of the international Waterkeeper Alliance, a network of water advocates with more than 300 programs in 44 countries on 6 continents. California Coastkeeper Alliance works with local Waterkeepers develop, implement, and defend policies that meet the needs of California’s distinct communities and ecosystems. Together, we provide the public with the tools and information needed to hold decision-makers accountable and to be effective local water stewards.
