4. What should people do if they are given an Evacuation Order?
It is very important that residents follow the directions of emergency services personnel. As soon as advised, those affected should leave their homes or businesses and go either to friends and relatives in unaffected areas or to the designated registration and reception centre. Generally, we will attempt to provide early warning, giving people a chance to remove themselves and their treasured belongings in advance. However, this is not always possible.
Whether you choose a private location or a reception centre, all residents are asked to register or leave word with neighbours so emergency personnel know you are safe. [Click here for more info on Evacuation Orders]
5. How will we know if we are being evacuated?
Regular bulletins will be issued to all major media and be posted on the City website. Those in high-risk areas will receive an early warning notification. In Chilliwack, we will use Shaw TV and Star FM as well as regional media. In the event of a large-scale evacuation, personnel will go door-to-door.
6. How much notice will a person have that their area is going to flood?
While it is difficult to predict, weather patterns and forecasts will be the primary indicator of Fraser River water levels, and the City relies heavily on the Ministry of Environment River Forecast Center for regularly updated flood forecasts.
7. In the event of a flood, how long would it be before the water recedes?
In general, the exact time frame and level of high water is entirely dependent on weather patterns. A rapid heating pattern would result in higher water levels over a shorter duration, and a cooler pattern in lower water levels over a longer duration.
8. What will happen to the sewer systems if there is a flood?
If there is high water, that is, flooding of the unprotected areas outside of the setback dykes, the sewer system will not be impacted, as the Water Pollution Control Plant is situated inside of the setback dykes along Wolfe Road. If flooding of the community in the vicinity of the Water Pollution Control Plant were to occur, however, the Plant could be rendered incapable of treating sewage and sewer backups may occur.
9. Would our water supply be affected in any way?
The community's water supply comes from wells located outside of the flood plain in the Sardis-Vedder Aquifer, which would not be impacted by a Fraser River flood. However, in the event of a catastrophic flood, the water distribution system in lower areas of the community could be impacted.
