In 2017, the Broward County Board of County Commissioners established a Future Conditions Map Series, intended to evolve with the application of best available science to develop models and provide data to update design requirements for land use decisions, accounting for future flood and climate risks. The first map in this series is the Future Conditions Groundwater Elevation Map, Plate WM 2.1 Future Conditions, which represents the expected future average wet season groundwater elevations for Broward County and is used when reviewing surface water management licenses.

The Future Conditions 100-Year Flood Elevation Map is used to improve standards for flood protection. This modeling effort accounted for future changes in sea levels, rainfall, saturated soil, and land use. The map serves as a regulatory tool for building standards

This PDF map identifies areas near tidal water bodies at increased risk of inundation under a 3.3 foot sea level rise scenario, projected to occur as soon as 2070.

Consistent seawall heights are necessary to protect the community from escalating impacts. Broward County has created regional guidance so that coastal flood barriers will continue to provide protection, even under future sea level rise conditions.
