Flooding can be caused by several events. Heavy rains alone or mixed with spring’s melting snow can create excessive runoff on rivers and lakes. Ice jams can also cause flooding when water upstream is blocked by ice downstream. On the coast, flooding can occur when seasonally high tides are amplified by a severe storm or tsunami. You can view the Flood Zone Map to see the areas of potential flood.
Important Notice Regarding Insurance
Flood damage is not often covered by your homeowner’s insurance policy. In addition, insurance can't replace your photos and other memory keepsakes. Consult your insurance broker regarding your coverage and take proactive steps in moving your precious items out of a flood area for safeguarding.
Where there is immediate threat of flooding
- Shut off power to premises
- If the main switch is in an area that is already wet, stand on a dry board and use a dry stick to turn switch off.
- Do not attempt to turn off power if the room is already flooded
- Disconnect all electrical appliances, and if possible, move them to a higher level. Thermally insulated appliances such as freezers, refrigerators and ranges should be given priority
- Any appliances that cannot be moved should have motors, pumps, fans, etc. removed to higher levels
Gas or oil furnaces and appliances
- Oil or water tanks will float if not full. Fill if possible, then plug vent holes. If unable to fill, weight down with sandbags or wedge against a solid object
Plumbing fixtures and water supplies
- Turn off water supply
- Plug all basement sewage connections, eg. toilet, sinks, showers, etc. with a wodden plug or other device. The plug should be held in place with a weight or wood brace to the joist above.
- Pesticides, weed killers, fertilizers and other articles that may cause pollution should be moved to higher levels.
- To relieve overloading the sewer system, disconnect any downspouts draining to them.
- Move or remove all furniture and personal eff ects that could be damaged by flooding or that may float and cause damage.
- If constructing a sandbag dike, build it on high ground close to your home or building. This ensures fewer sandbags will be needed and the dike will be less exposed to nearby streams.
- Dig a trench one bag in depth and two bags wide as a foundation for the dike structure.
- To be effective, a dike must be three times as wide at its base as it is high.
When Flooding Occurs
View the Fraser River Flood Plain Preparedness Phases that have been established to ensure that a flood is managed by Surrey's emergency response teams.
If rising waters become a threat to your safety, obey all officials who are involved in rescue or flood control operations, including those directing traffic, as water can be deeper than it appears.
It only takes two feet (60 cm) of moving water to sweep a car away, and as little as six inches (15 cm) to cause you to fall.
- Climb to high ground and stay there.
- Avoid walking through any floodwaters.
In a vehicle
- Take extra care when driving. Familiar roads will appear drastically different when covered by floodwaters.
- Be on the lookout for damaged bridges, slides and washouts, and especially downed power lines.
- If you come to a flooded area, choose an alternate route.
- If your car stalls, abandon it immediately and climb to higher ground.
In your home (as much as time allows)
- Be sure you know where your emergency supply kit is.
- Follow your family emergency plan.
- Ensure each member of the family has warm clothing and waterproof footwear and outerwear.
- If you need to use a different meeting place than agreed on in your emergency plan because of flooding, make sure every member of the household knows where the new location is. Provide younger children with a note sealed in plastic stating the family’s destination.
- Turn off power and unplug all appliances.
After a flood
- As an individual, family or small business, you may be able to receive Provincial Disaster Financial Assistance (DFA) as a victim of flooding, when insurance is not available.
- You may be able to receive assistance through the through their Financial Assistance Program, which raises donations. But, this assistance and amount depends on how many donations they receive.
