The floodplain is any area that is suceptible to being inundated by water from any source. Mostly, this is the area adjacent to a river, creek, lake, stream, or other waterway that is subject to flooding when there is a significant run-off event. The floodway is the channel of a river or other watercourse that carries the deepest, fastest water downstream. The technical definition of a floodplain as it pertains to the development process can be found in the Ada County Zoning Ordinance: 8-3F-4.
