Flood Response


Each year, municipalities that border the Fraser River, including the Township of Langley, prepare for the possibility that melted snowpacks from the mountains could flood local rivers. Residents and property owners are encouraged to be prepared for the threat of flooding as well.

The Township maintains a comprehensive flood risk protection program. This program is reviewed annually and includes regular inspections. Township staff closely monitors snowpack and runoff forecasts as provided by the Ministry of Environment.

River Levels at the Mission Gauge

The Township’s Flood Response Plan for freshet is triggered by river levels measured at the Mission Gauge. When levels are expected to continue to rise, action will take place as detailed in the chart below. Closures will be implemented based on actual field observations.

Risk of Flooding During Heavy Rainfall

During peak storm periods, conditions can change quickly. In the event of heavy rain, blockages can lead to a serious flooding problem on private as well as public property.

To minimize potential problems, here are a few things you can do at home:

  • Clear leaves and debris from nearby curbs, catch basins, and driveway culverts, especially during heavy rain.
  • Clean your gutters and ensure water from downspouts drain away from your residence.
  • Do not rake or push leaves onto the street or into open ditches.
  • Compost leaves or place them in your Green Cart for pickup.

Tips to Keep in Mind

  • Emergencies can strike anytime. Prepare yourself and your family by taking just a few simple steps: Know the risks, make a plan, and prepare an emergency kit.
  • Sand is available at the Township of Langley Operations Centre at 4700 - 224 Street, 24 hours a day. Sandbags are available during regular business hours: Monday to Friday, 8:30am to 4:30pm.
  • If a road is closed due to flooding, do not attempt to drive through the closure, even if you feel your vehicle is capable of doing so. Follow all signage and detour directions.
  • If you see pooling of water or flooding on the street, call the Engineering Division at 604-532-7300 between the hours of 8:30am and 4:30pm. For after-hours flooding emergencies, call 604-543-6700.
