E.O. 11988
E.O. 11988 remains the framework for federal agencies to
avoid or minimize actions in or impacting floodplains. E.O.
11988 defines “action” as any federal activity, including
(1) acquiring, managing, and disposing of Federal
lands, and facilities; (2) providing Federally
undertaken, financed, or assisted construction and
improvements; and (3) conducting Federal
activities and programs affecting land use,
including but not limited to water and related land
resources planning, regulating, and licensing
activities.
For E.O. 11988, the floodplain had been defined as the 1%
annual chance floodplain (i.e., 100-year floodplain), which

is known as the base flood elevation (BFE) floodplain.
