Adapting to sea level rise raises significant legal questions for local governments, especially in California. On the one hand, taking action could decrease risk to the community, but increase litigation risk from aggrieved property owners or public interest groups, depending on the nature of the action. On the other hand, a local government could decide not to act, exposing people and infrastructure to excess risk, while potentially exposing itself to litigation if the lack of action causes harm to individuals or public trust property. Risk is thus unavoidable.
