Floodplain Hazard Map(s)


Purpose

To provide an overview of the natural hazards in the Chilliwack River Watershed, such as flooding and unstable terrain.

Data source(s)

Fraser Valley Regional District Bylaw 681, 2005.

Explanation

Designated Floodplain:  A lowland area, whether floodproofed or not, which, by reason of land elevation, is susceptible to flooding or erosion from an adjoining watercourse, lake, or other body of water and pertains to the areas shown in Schedule "B" of this Bylaw.

 Alluvial Fans: Fan-shaped accumulations of alluvium deposited at the mouth of a ravine or at the juncture of a tributary stream with the main stream.

 60 m Watercourse Setback No development can occur within 60 m of the natural boundary of the watercourse.

 30 m Watercourse Setback: No development can occur within 30 m of the natural boundary of the watercourse.

Note that there are a number of additional hazards that were mapped in an extensive study conducted by Hay and Company in 1992 (e.g. erosion, slope, debris flows and floods).  Please contact the FVRD planning department to view these maps.
