Residents and businesses in Broward County are encouraged to view the current flood zones map and FEMA’s preliminary flood zones map to better understand their potential flood risk and to help identify steps they may need to take to protect against property damage and loss.
The maps are used by insurance companies for flood insurance purposes and the base flood elevations must be used for all new construction and substantial improvements to existing construction.
