Natural Floodplain FFCNA

This data layer identifies natural features within the 100-year floodplain as determined by from three primary sources: 1) FEMA Digital Flood Insurance Rate Map database 2001-2017 (DFIRM) for 63 counties; 2) FEMA Digital Q3 Flood Data 1996 for 4 counties; and 3) a surrogate floodplain dataset based on overlap of wetlands and hydric soils for gaps in FEMA data. The data were prioritized based on the degree of “naturalness” of the floodplain, which was estimated based on overlap with Land Use Intensity index and FNAI Potential Natural Areas.

Value 1 = Priority 1 (Highest); Value 2 = Priority 2; Value 3 = Priority 3; Value 4 = Priority 4; Value 5 = Priority 5; Value 6 = Priority 6 Data download page This dataset was developed by Florida Natural Areas Inventory as part of the Florida Forever Conservation Needs Assessment, with support from the Florida Department of Environmental Protection.
