The flood areas in the City of Kennewick are classified as either one of two types:

(1)

Floodway: Floodways are defined as the channel of a stream and adjacent land areas which are required to carry and discharge the flood water or flood flows of any river or stream associated with a regulatory flood.

(2)

Flood Fringe: The flood fringe is defined as that land area which is outside a stream's floodway, but is subject to periodic inundation due to flooding, associated with a regulatory flood.

These flood areas have been accurately delineated based on hydrologic and hydraulic studies completed by the Federal Emergency Management Agency in 1981, and as subsequently revised and amended.

The methodology and detail of these studies is accepted as the best available.

(Ord. 5206 Sec. 4, 2007)

(1)

All areas within the City meeting the frequently flooded designation criteria in the Identification and Delineation Manual, regardless of any formal identification, are hereby designated critical areas and are subject to the provisions of this Title.

(2)

The approximate location and extent of frequently flooded areas are shown on the adopted Critical Areas Map (Exhibit 3, or the latest revision of this map). Maps from the Federal Emergency Management Agency, as part of the National Flood Insurance Program (completed May, 1981; last revised June 15, 1994), clearly delineate frequently flooded areas. The present boundaries of the floodway and 100-year floodplain are those designated on the flood boundary and floodway maps contained in the Federal Emergency Management Agency report entitled, "Flood Insurance Study - City of Kennewick, Washington" (completed May, 1981; last revised June 15, 1994) and areas of special flood hazard outlined on the City of Kennewick Zoning Map.

(Ord. 5206 Sec. 4, 2007)

Title 15 (Buildings and Construction) and Chapter 18.66 (Flood Damage Protection) of the City of Kennewick Code regulate proposed activities adjacent to or within frequently flooded areas. If allowed, any structures permitted in the designated flood areas are subject to the floodproofing regulations provided in Title 15 and Chapter 18.66.
