Southeast Florida is widely considered one of the more vulnerable areas in the United States to the impacts of sea level rise due to our topography, extensive coastline, and porous limestone bedrock. The region relies heavily on our coastlines for tourism, recreation, development, and protection from hurricanes. The City of Coral Gables recognizes this vulnerability, especially with over 47 miles of coastline and waterways, and is developing short and long-term strategies, that are outlined below, to improve the City’s resilience.
|Mindful of the growing threat posed by sea level rise and the many legal complications that will accompany it, Coral Gables commissioned the drafting of a white paper that lays out a comprehensive overview of various sea level rise adaptation policy options at the City's disposal and details key legal considerations and implications surrounding those various adaptation options, including, for example: financing options available under Florida law, various regulatory and market-based tools available (and municipal liability risks associated with each), the need for updating local governments' comprehensive plans, and even factors to consider in long-term retreat planning. This white paper aligns with the Regional Climate Action plan’s categories of public outreach, sustainable communities and transportation planning, risk reduction and emergency management, and public policy.|
What is Sea Level Rise?
As the temperature of the earth changes, so does sea level. Temperature and sea level are linked for two main reasons:

Global sea level has risen about 8 inches since 1880, and the rate of rise is accelerating. Rising seas dramatically increase the odds of damaging floods from storm surges. One analysis finds the odds of “century” or worse floods occurring by 2030 are on track to double or more, over widespread areas of the U.S. Across the country, nearly 5 million people live in 2.6 million homes at less than 4 feet above high tide — a level lower than the century flood line for most locations analyzed.
Actions the City of Coral Gables is Taking to Minimize the Effects of Sea Level Rise
Recap of the Coral Gables 3-Part Sea Level Rise Discussion Series
During the 3-part discussion series attendees were able to learn from experts about the potential impacts of sea level rise in the community, review potential adaptation and mitigation strategies, and discuss public policy implications of sustainable development, and much more! The discussion series was organized in partnership between Coral Gables Commissioner Patricia Keon and the Florida International University Sea Level Rise Solutions Center.
