Fraser River Freshet Prepardness Phases

The City of Surrey's established these 4 phases to ensure that the potential Fraser River Flood Plain flood is managed in an efficient manner by our emergency response teams.

Review the outline of each phase, and carefully review the Residential Flood Preparedness to become educated on the potential impact of the Fraser River Freshet (snow pack).

Phase 1 (based on definitive Ministry of Environment forecast)

  • Implement City Communication Plan.
  • Establish Flood Information Phone Line.
  • Begin holding Flood Group meetings.
  • Inspect all flood-related equipment and structures.
  • Hand out information packages to residents and businesses within the affected area.

Dyke Protected Areas: Based on definitive Ministry of Environment (MOE) forecast. Areas outside of dykes are based on definitive MOE forecast.

Phase 2 (based on the Mission Gauge)

  • Deploy all flood equipment, internal and external.
  • Transfer in key or qualified personnel.
  • Cancel leave for qualified flood personnel.
  • Dyking Operations - Dyke is reinforced and manned on a continual basis.
  • Notify residents of imminent flooding and voluntary evacuation.
  • Emergency personnel work with Engineering on assessment.

Dyke Protected Areas: Mission Gauge 6.0 metres. Areas outside of dykes Mission Gauge 6.0 metres.

  • Crews to be on more stringent dyke inspections (Daily at Mission 6.5 metres, 24 hour at Mission 7.0 metres.)
  • Have assessment records and current reports of dyke conditions.
  • Begin placement of stoplogs to close low dyke sections.
  • Inform those outside of dykes to expect flooding.

Dyke Protected Areas: Mission Gauge 6.5 metres and 7.0 metres. Areas outside of dykes Mission Gauge 6.5 metres.

Phase 3*(based on the Mission Gauge and the Ministry of Environment)

  • Final dyking and stop-blocking.
  • Establish reception centres.
  • Establish EOC.
  • Evacuate all residents in affected areas.
  • Ambulance to set up aid station during evacuation operations.
  • Transport residents to reception centres.
  • Sweep areas for possible victims or residents not obeying evacuation order.
  • Fire Department to supply rescue service flood operations personnel. All flood operations personnel to be aware of staff evacuation procedures.
  • Engineering and B.C. Hydro to shut down utilities.

Dyke Protected Areas Mission Gauge 7.6 metres for evacuation – MOE river forecast center will provide 4-day alert  (Crest at Mission is 8.5 metres). Areas outside of dykes Mission Gauge 7.0 metres for alert 7.3 metres for evacuation (CNR at 176 overtops when Mission gauge at 7.6 metres).

*Phase 3: Evacuation Alert will occur for non-dyked areas at the 7.0 metre water level (Mission Gauge). Full evacuation (State of Local Emergency Declaration) will commence at the 7.3 metre water level in non-dyked areas and at the 7.6 metre water level in the dyked area ( please refer to the map above for dyked versus non-dyked areas).

Phase 4 (Post crest and receding)

  • Inform all flood fighting personnel of cresting. Evacuate.
  • Sweep area for victims.
  • Assessment of area by Engineering, B.C. Hydro, Health Unit, etc. (this to be done when the river has receded to a point where personnel can safely navigate the zone).
  • Return order needs to be given when clean supply of drinking water can be provided and when the means for human waste and flood debris removal are available.
  • Return or relocate residents.
  • Once stable levels, boat operations will commence.
  • Inventory equipment and return to pre-flood locations.
  • Release transferred in and volunteer personnel.
  • Critique operation.
  • Recovery Plan implementation.

Dyke Protected Areas Post crest and receding (Crest at Mission is 8.5 metres). Areas outside of dykes Post crest and receding (Crest at Mission is 8.5 metres).

See if you or your business is in an area that might be affected by the potential Fraser River Flood Plain flood, to be prepared in the event of this peril.
