Background“The State and Regional Water Boards have a keyrole in the State’s implementation plan known asSafeguarding California.” – San Diego Water Board
• Safeguarding California (2016)“We use a number of words, including adaptation,
resilience, readiness, and safeguarding, to describe asimple concept: ensuring that people, communities,and natural systems are able to withstand the impactsof climate disruption.”
