Service Description: This map identifies future conditions water storage needs in Broward County based on hydrologic modeling accounting for the combined influence of sea level rise, groundwater table rise, rainfall intensification, and storm surge on drainage and existing water management systems as of 2024. This map accounts for the additional water storage required across sub-basins in order to deliver the level of service as modeled for Tier 2 adaptation as presented in the 2025 Countywide Risk Assessment and Resilience Plan. It establishes the volume of additional storm water storage required to deliver flood mitigation across individual sites and collectively through planning and redevelopment.

Description: The Future Conditions 100-Year Flood Elevation Map project is intended to advance the resiliency efforts in Broward County by setting the foundation to improve standards for flood protection. The flood elevation mapping results (representing a 1% annual chance) are intended to serve as the basis for establishing future finish floor elevations for new buildings and major redevelopments in the County. The Future Conditions 100-Year Flood Elevation Map was developed through integrated hydrologic modeling of surface and groundwater, using DHI’s MIKE SHE/MIKE Hydro River model tools. This model incorporated future land use changes and the effects of projected sea level rise and precipitation changes on predicting future flood conditions.
The flood area approach for conveying the future 100-year flood elevation data for the updated community flood map was vetted through a collaborative process reflecting input from Broward staff and key stakeholders.
