The national fire record shows next to nothing around Bridgeland/Riverside, 0% of the land within 25 km since 1986 (0.000% a year). Earthquake risk in Bridgeland/Riverside is ordinary: NRCan’s model puts building losses at $0.023 a year per $1,000 of value, close to the typical town’s $0.030. Radon is about average around Bridgeland/Riverside: 8.1% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Bridgeland/Riverside a grade of B+, from earthquakes and radon alone.
What stands out about Bridgeland/Riverside’s hazards
Four national sources, each read for Bridgeland/Riverside: earthquakes, radon, past fires and flood studies.
What Bridgeland/Riverside faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.
Wildfire
Earthquakes
Radon

Bridgeland/Riverside grades B+ for hazard risk
Earthquake risk and radon make Bridgeland/Riverside’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #282 of 474 in Alberta and #1,102 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.
Wildfire is rare near Bridgeland/Riverside: 0% of the land within 25 km burned since 1986, 0% within 5 km

Get ready for what Bridgeland/Riverside faces
Practical steps for Bridgeland/Riverside’s hazards, most pressing first.
- Test for three months in winter.
- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Never drive through floodwater.
- Move papers and medicines upstairs.
- Ask whether your street is mapped.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Bridgeland/Riverside’s figure is its subdivision’s.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Bridgeland/Riverside.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Bridgeland/Riverside’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Bridgeland/Riverside is its health region’s, the survey’s design unit.
