Climate Change & Sea-Level Rise

The Commission owns and manages millions of acres of sovereign lands and resources that it holds in trust subject to the common law Public Trust Doctrine. If unaddressed, sea-level rise can have catastrophic consequences for these lands and resources. The Commission works hard to facilitate sea-level rise preparedness, with an emphasis on protecting California’s public trust lands and the public’s right to access and enjoy these lands. The Commission partners with the Legislature and federal, state, and local agencies to stay at the forefront of efforts to mitigate the impacts of sea-level rise on the lands and natural resources entrusted to its care.
