This resource is an ESRI file geodatabase that contains floodplains for the continental United States. The geodatabase contains one feature class for each state. This is the the first version of the data which also includes wetlands and other water bodies as floodplains. More details on how the floodplains are extracted from the SSURGO data can be found in the following JAWRA article: Sangwan, Nikhil, and V. Merwade, A faster and economical approach to floodplain mapping by using soil information, Journal of American Water Resources Association, 51(5): 1286-1304. (2015)
