Section 380.0552(9)(a)2., Florida Statutes, requires that the local governments within the Florida Keys Area of Critical State Concern establish goals, objectives, and policies that “protect public safety and welfare in the event of a natural disaster by maintaining a hurricane evacuation clearance time for permanent residents of no more than 24 hours.” 

FloridaCommerce, in its capacity as the state land planning agency, assists the local governments in meeting this statutory requirement by updating the data for the Florida Keys Evacuation Model as professionally acceptable sources of information are released pursuant to Administration Commission rules. With new census information recently available and the close of a 10-year planning horizon initiated in 2013 and ending in 2023, FloridaCommerce has conducted new baseline modeling and data gathering. 

Please see below a link to view and/or download the Florida Keys Hurricane Evacuation Modeling Report which contains a summary of FloridaCommerce’s 2023 Hurricane Evacuation Modeling, as well as a history of managed growth in the Florida Keys and an overview of the robust community engagement and public input coordinated by FloridaCommerce to support the 2023 modeling efforts. This report includes research to help inform future policy decisions that may be considered by state and local officials to ensure the continued safety and well-being of Florida Keys residents.

Florida Keys hurricane evacuation modeling protects Florida Keys’ residents and visitors, ensuring they are able to safely evacuate before a storm. This effort is in response to the unique needs of local governments in the Florida Keys – unlike anywhere else in the state – and is a collaborative effort between the state and local partners. 

FloridaCommerce provided two opportunities for local governments and citizens to attend the Florida Keys Evacuation Modeling webinars to discuss the 2023 Florida Keys Hurricane Evacuation Modeling process and draft results of the modeling.

The Florida Keys Evacuation Modeling Webinar #1 was held on Tuesday, November 14, 2023, from 3:00 p.m. to 4:00 p.m., Eastern Time.

The Florida Keys Evacuation Modeling Webinar #2 was held on Thursday, November 16, 2023, from 2:00 p.m. to 3:00 p.m., Eastern Time.

If you have questions relating to the Florida Keys Hurricane Evacuation Modeling that you would like us to address during the webinars, please email them in advance to the Bureau of Community Planning and Growth team at

Memorandum of Understanding

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 FloridaCommerce and the Florida Division of Emergency Management to enter into a Memorandum of Understanding with Monroe County, the Village of Islamorada, and the Cities of Marathon, Key West, Key Colony Beach, and Layton regarding hurricane evacuation modeling.

The Memorandum of Understanding addresses 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 is 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 the Memorandum of Understanding to be formulated, FloridaCommerce 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
