For more information about this layer please see the GIS Data Catalog. A compilation of best available floodway boundaries. A floodway is the channel of a stream plus any adjacent floodplain area that must be kept free of encroachment so that the 1 percent annual chance flood can be carried without substantial increases in flood heights.
