Douglasdale/Glen grades B+ for hazard risk
The grade weighs Douglasdale/Glen’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #282 of 474 in Alberta and #1,102 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Few fires near Douglasdale/Glen: 0% within 5 km, 0% within 25 km
Past fire around Douglasdale/Glen’s homes, from the national burned-area record, with the fuel within 5 km.
Fire claims 0.000% of the land around Douglasdale/Glen each year, a low band, with the typical Canadian town at 0.000%.
No fire has burned within 5 km of Douglasdale/Glen’s homes since 1986; the nearest burn is 9.7 km away.
Forest makes up 0.2% of the land within 5 km of Douglasdale/Glen and 0.7% within 25 km, little for a forest fire to run through.

Flood studies don’t enter the grade; they are listed so you can open the official map for Douglasdale/Glen.
The inventory’s own caution (NRCan): “The Canada Flood Map (CFM) does not include every flood hazard map in Canada and may be incomplete or contain inaccuracies. It should not be relied upon as the official source of flood mapping information. Furthermore, if a map appears to be missing, this does not necessarily mean that the area has never been mapped.

Get ready for what Douglasdale/Glen faces
What to do about the hazards Douglasdale/Glen faces, and what to ask before you buy.
- 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
- Radon is a survey. Radon figures pool the survey’s home tests by area: postal areas once their boundaries arrive, the 2007 health region around Douglasdale/Glen until then.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Douglasdale/Glen’s included.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Douglasdale/Glen without grading them.
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Douglasdale/Glen.
Questions about flooding and hazards in Douglasdale/Glen
