Unified Sea Level Rise Projections

The Southeast Florida Regional Climate Change Compact first produced a Regionally Unified Sea Level Rise Projection for Southeast Florida in 2011. The Projection was updated 2015. In 2019, the Compact again convened an ad hoc Sea Level Rise Work Group to update the Projection, composed of scientific experts within the academic community, as well as local, regional, and federal government. 

The Climate Compact’s Regionally Unified Sea Level Rise Projection and accompanying Guidance Report are adopted for use by each of the four-counties’ Boards of County Commissioners. The Compact expects County adoption of the 2019 Projection to be complete by Spring of 2020, after which the Compact will release the Guidance Report supporting the Projection, containing directions and specific examples of how the projection can be used by local governments, planners, designers, engineers, and developers. The Projection is reviewed and updated every five years, or sooner, as a result of ongoing advances in scientific knowledge and modeling via the peer-reviewed literature related to global climate change.    

The Regionally Unified Sea Level Rise Projection is a key planning tool produced by the Compact to aid in understanding of vulnerabilities and to provide a basis for adaptation strategies, policies, and infrastructure design in the Southeast Florida region. Prior to producing a unified projection for the region, the diversity of local sea level rise projections was a barrier to achieving regionally consistent adaptation strategies and policies, and to effectively influence supportive policies at the state and federal levels.

Integrating the Unified Sea Level Rise Projection into Local Plans

This is a guidance document created by the Southeast Florida Regional Climate Change Compact as an addendum to the Regional Climate Action Plan (RCAP) Workshop #10: “Essential Tools: Integrating the Southeast Florida Sea Level Rise Projections into Community Planning” held on July 14, 2016. It focuses on the increasing number of local governments that are independently planning for sea level rise compliance with state law.
