Within the City of Chilliwack, there are floodplain areas for both the Fraser River and Vedder River. Portions of Greendale and Yarrow lie within the floodplain for both rivers.
The flood risk associated with these two river systems is different, and therefore the City has separate Flood Response Plans to manage the risks. This webpage contains general information regarding flood protection and emergency preparedness for residents. For more specific information regarding the Fraser River or Vedder River, please visit these webpages:
General Flood Hazard Management:
Flood hazard management is accomplished through a variety of measures, including:
- Flood Protection Infrastructure
- Emergency Dyke Upgrades Plan (identifies how to address priority areas for upgrading under emergency situations)
- Flood Response Plans for the Fraser River and Vedder River
- Flood construction levels and setbacks as specified in the Floodplain Regulation Bylaw
River Forecast Centre:
The Provincial River Forecast Centre collects and interprets snow, meteorological and streamflow data to provide warnings and forecasts of stream and lake runoff conditions around the province. Visithttp://www.env.gov.bc.ca/rfc/ for current reports.
The City of Chilliwack uses the information provided by the River Forecast Centre when carrying out flood response activities.
Flood and Emergency Information for Residents:
Download and print an Emergency Preparedness basic kit checklist (Grab & Go Kit). There are a number of resources that you can access to be prepared in the event of a flood.
Additional Information for the Agricultural Sector:
The following websites provide information on flood and emergency preparedness for the agricultural sector: BC Milk Producers Association (www.bcmilkproducers.ca or 1-877-462-2672); Ministry of Agriculture and Lands (http://www.gov.bc.ca/al or 1-888-221-7141); BC Horse Council (http://www.hcbc.ca/ or 1-800-345-8055).
Due to variables such as weather, we cannot predict a flood with 100% certainty. Therefore, it is important that you make your plans on the assumption that flooding is a real possibility. The best thing for people to do is to review or establish personal and neighbourhood emergency plans and consider family members or friends who may need additional assistance. Please help those folks to be ready as well.
It is important to note that even if your home or business is located on higher ground, a serious flood event would result in a loss of key services like water, sewer, electricity and gas. In that case, a City-wide evacuation could occur. All residents should be prepared for at least a 72-hour period without services. We will provide as much information as possible to keep the public informed as waters start to rise.
