Mandated Planning for Climate Change

Problem, research strategy, and findingsFlorida’s 2015 Peril of Flood Act requires that coastal localities incorporate sea level rise (SLR) planning policies into their comprehensive plans. We surveyed planners and reviewed more than 150 plans to determine how communities responded to the state mandate along three domains: planning intelligence, SLR responses, and collaboration. We learned that the mandate spurred SLR planning, but that local SLR planning responses varied widely, ranging from complacent compliance to progressive planning responses. Further research is needed to clarify underlying motivators for these varied responses, as well as connections between policy adoption and implementation.Takeaway for practiceFlexible mandates allow for discretion in how localities respond to complex, ever-changing, long-term, and uncertain phenomena like climate change and SLR. Commitment to addressing these challenges can be bolstered by state mandates that provide political cover and an impetus to move adaptation planning forward. Such flexibility can lead to inconsistent and vague policies. Thus, mandates can spur local policy adoption but cannot ensure substantive responses to climate change. Meaningful responses to climate change adaptation still depend heavily on local commitment, capacity, and competence of planners.
