Be Prepared for Flooding

Approximately 85 per cent of Pitt Meadows is located within the Fraser River and Pitt River floodplains, and flooding can happen any time.

Pitt Meadows is susceptible to flooding due to heavy rain, rain on snow, spring freshet (river flooding from heavy rain or snow melt), and mechanical failure of pump stations.

Current Flood Status

July 28, 2020: The City is currently monitoring river levels (PHASE 1 below). No active flooding.

Freshet – River Flooding possible from April to July

The freshet period—river flooding due to heavy rain or snow melt-- extends from April to July. Annual flooding in Pitt Meadows is most common in May and June.

Freshet is forecasted using snowpack estimates during winter, which can help downstream municipalities get prepared. Weather events, such as heavy rain can be more difficult to predict.

What Does the City Do to Prepare for Flooding?

The City is surrounded by 60 km of dikes, which are critical to protecting the City’s low-lying areas and key infrastructure from river flooding.

Flood mitigation infrastructure also includes ditches, pump station and flood boxes.

Each year, the City prepares for flooding by:

  • reviewing freshet (river flooding due to snowmelt and forecasts using snowpack estimates during winter
  • maintaining pump stations
  • inspecting dikes
  • clearing culverts
  • monitoring river level gauges.

Please note: We do not protect private property from flood risk. Property owners are responsible for protecting their property.

Flood Warnings and Monitoring

During periods of high flood risk, City staff monitor Environment Canada’s weather forecasts and updates from the provincial River Forecast Centre, which provides information on streamflow conditions, and flood warnings and advisories.

  • High Streamflow Advisory means that river levels are rising or expected to rise rapidly, but no major flooding is expected.  Minor flooding in low-lying areas is possible.
  • Flood Watch means that river levels are rising and will approach or may exceed the river bank.  Flooding of areas adjacent to affected rivers may occur.
  • Flood Warning means that river levels have exceeded the river bank or will exceed the river bank imminently, and flooding of areas adjacent to affected rivers will result. 

The Fraser River is the most significant flood hazard in the City, as it undergoes annual freshet (flooding due to snowmelt or heavy rains). It has the ability to cause the most damage to the region due its extensive drainage area of roughly 250,000 square kilometres, which extends from the Rocky Mountains to the Lower Mainland of B.C.

Stay Informed

The City posts flood warnings and advisories on the website and social media channels. Stay tuned to local news media for updates.

Note: The index identifies geodetic elevations and corresponding Mission gauge levels.  Mission gauge levels are monitored for flooding and the City’s Flood Response Plan is based on these levels.

How You Can Prepare for a Flood

Flooding is a risk in Pitt Meadows, and it’s important to be prepared before, during and after a major flood.

Planning and Flood Mitigation

The City invests in emergency planning and infrastructure maintenance and upgrades for flood mitigation, response and recovery.

Flood mitigation plans

The City received $412,000 in funding as part of the Government of Canada’s National Disaster Mitigation Program for the development of a Flood Mitigation Plan to identify gaps and establish priorities to protect residents, farms and businesses in the event of a flood or breach in our dike system. The plan is expected to be completed in 2020.

Pitt Meadows is working with the Fraser Basin Council and Metro Vancouver to develop a regional flood management strategy to address complex inter-jurisdictional flood mitigation issues.

Current flood mitigation infrastructure in Pitt Meadows consists of 60 km of dikes, along with ditches, pump stations, and flood boxes.

 In 2018, the City completed a federally-funded Flood Hazardous Risk Assessment, which showed that the City’s dike system does not meet current standards, which poses an increased risk of flooding. The City continues to work closely with Metro Vancouver and the federal and provincial to address dike improvements. 

The City’s six pump stations are critical for flood protection and public safety.

  • In 2020, the City received funding from the Province of B.C.’s Community Emergency Preparedness Fund to replace the Fenton Road Station pump and install a back-up generator for this location and the Baynes Road pump. This work will take place from 2020 to 2022.
  • Work is underway to replace back-up generators for the pump stations at Kennedy Road, McKechnie Road and Area 1 funded by a previous grant. This work is anticipated to be completed in summer 2020.

Flood response plan

The City has a flood response plan based on Fraser River levels in Mission, which may flood first. In the event of a major emergency, the City’s Emergency Operations Centre (EOC) will be activated. The City’s emergency coordinator works closely with the Katzie First Nation’s EOC.
