Part of the Legislative intent for the designation of the Florida Keys as an Area of Critical State Concern was to "ensure that the population of the Florida Keys can be safely evacuated" before a hurricane storm event. The state and local governments of the Florida Keys have had a long history regarding hurricane evacuation modeling in response to constraints faced by these local governments not seen anywhere else in the state. In 2011, the Governor and Cabinet, seated as the Administration Commission, directed the Department of Economic Opportunity and the Florida Division of Emergency Management to enter into a Memorandum of Understanding with Monroe County, Village of Islamorada, and the Cities of Marathon, Key West, Key Colony Beach, and Layton regarding hurricane evacuation modeling.

The Memorandum of Understanding will address the input variables and assumptions, including regional considerations, to depict hurricane evacuation clearance times for the population of the Florida Keys. The Memorandum of Understanding will be the basis for an analysis of the maximum build-out capacity in the Florida Keys while maintaining the ability of the permanent population to evacuate within 24 hours. In order for this Memorandum of Understanding to be formulated, the Department conducted a series of meetings for those chosen to represent their agencies and/or local governments on the 2012 Hurricane Evacuation Clearance Time Work Group.
