The following categories of frequently flooded areas are established for the purposes of classification:
(1) Floodway. Floodways are defined as the channel of a stream and adjacent land areas, which are required to carry and discharge flood waters or flood flows of any river or stream associated with a regulatory flood.
(2) Special Flood Hazard Areas. The area adjoining the floodway, which is subject to a one percent or greater chance of flooding in any given year and determined by the Federal Insurance Administration.
(3) Floodplain. The floodway and special flood hazard areas.
These flood areas have been delineated based on studies completed by the Federal Emergency Management Agency (FEMA) for the National Flood Insurance Program. The City of Pasco may use additional flood information that is more detailed than that provided in the flood insurance study conducted by FEMA to designate frequently flooded areas, as available.
