Both Broward and Miami-Dade counties are already vulnerable to flooding

• Aside from the effects of SLR on coastal areas, Broward is currently vulnerable to flooding in which groundwater is lifted to the surface by high tides as a consequence of low surface elevations. UMD is much less vulnerable to tidally induced groundwater flooding. Changes in precipitation patterns can affect depth to groundwater and hence risk of flooding.

Areas within each county are at risk of flooding from both climate impacts and asset growth

• Significant amounts of property are at risk in both counties, with Broward ($12 billion) having significantly more at risk than UMD ($2.1 billion). Values of property at risk are expected to grow.
• Directing growth toward areas of higher ground (UMD) or concentrating it in certain transportation corridors (Broward) could mitigate assets at risk.

The potential for saltwater intrusion into drinking water wells is concerning

• Saltwater intrusion has the potential to impact groundwater wells in Broward County by 2040.
• Saltwater intrusion is not projected to impact groundwater wells in UMD by 2040.
