South Florida is not just “going underwater”…but
• Tidal Flooding
• Saltwater Intrusion
• Failing Drainage
• Malfunctioning
Canals
• Beach Erosion
• Habitat loss

Who is responsible for addressing these risks?
• Public/private partnerships must increase
What can we do?• These new challenges will require a whole
new way of thinking about planning for risk

Strategies for
Adaptation Action
Areas may include
Protection
Accommodation
Managed retreat
Avoidance
Other options
![Page 11: Sea-level Rise Adaptation: Public and Private Responses · other areas, and/or the prevention of future development in high-risk areas. Avoidance Involves guiding development away](https://reader030.fdocuments.net/reader030/viewer/2022040508/5e4b3093bd329451b55afbc7/html5/thumbnails/11.jpg)
Protection
Strategies that involve “hard” and “soft” structurally defensive measures to mitigate impacts of rising seas in order to decrease vulnerability to coastal hazards while allowing structures and infrastructure to remain largely unaltered.
Accommodation
Strategies that do not act as a barrier, but rather alter the design through measures such as vertical elevation of structures or stormwater system improvements.
Managed Retreat/Relocation
Strategies that involve the possible relocation of existing development to other areas, and/or the prevention of future development in high-risk areas.
Avoidance
Involves guiding development away from areas subject to coastal hazards associated with sea level rise or where the risk of coastal flooding inundation is moderate at present but the risk may increase over time.

How can maps be more dynamic and translate the risk more effectively?

Standard flood models have severe limitations.
CRC adjusts its model with expected climate impacts.
