Chilliwack's downtown core has a significant flood risk

 Chilliwack's downtown core has a significant flood risk, especially in the event of a Fraser River dike breach. A recent study indicated that a large portion of the city, including downtown, is situated in a floodplain and is vulnerable to flooding. 

Here's a more detailed breakdown:

• High Flood Risk:

  A significant portion of Chilliwack, including a large part of the downtown area, is located in the floodplain and faces a high risk of flooding, particularly from the Fraser River. 
• Dike Vulnerability:

  The city relies on dikes for flood protection, but a breach, especially near the Rosedale-Mission Bridge, could lead to downtown being submerged. 
• Historical Flooding:

  Chilliwack has experienced devastating floods in the past, including the 1894 and 1948 floods, highlighting the area's vulnerability. 
• Climate Change Impacts:

  Climate change is expected to increase the frequency and severity of floods, further exacerbating the flood risk in Chilliwack. 
• Urban Core Vulnerability:

  A significant number of buildings in Chilliwack's urban core are located on the floodplain, making them vulnerable to flooding. 
• Specific Areas Affected:

  In the event of a dike breach, downtown Chilliwack, as well as parts of Sardis north of South Sumas Road, could be under water. 
• Importance of Flood Preparedness:

  The City of Chilliwack emphasizes the importance of flood preparedness, including being aware of flood zones and taking appropriate precautions.
