A flood study covers Deer Ridge: 1 on the national inventory, the newest from Government of Alberta
Since 1986 almost nothing has burned near Deer Ridge: 0% of the land within 25 km, or 0.000% a year. Shaking is about as much of a worry in Deer Ridge as in most places, at $0.023 a year per $1,000 of building value ($0.030 typical). Radon around Deer Ridge is ordinary for Canada: 8.1% of tested homes over the guideline (6.6% typical). Deer Ridge grades B+ for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Deer Ridge’s hazards

What Deer Ridge faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Deer Ridge: B+
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Deer Ridge with little fire nearby would get no credit for it.
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. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around Deer Ridge has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Deer Ridge’s residents live, and the fuel next to their homes.
The land within 25 km of Deer Ridge burns at 0.000% a year on average, the low band; the typical Canadian town: 0.000%.
The 5 km ring around Deer Ridge’s homes is clear of burns since 1986, the nearest 8.6 km out.
With 0.4% forest fuel within 5 km and 0.8% within 25 km, the land around Deer Ridge gives a fire little to burn.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).

To three decimals the burn rate around Deer Ridge is zero, as for 386 of the 478 towns in Alberta, while Wainwright reaches 1.43%.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
Like most of Canada’s 2,610 towns (92%), Deer Ridge is in the low band, with a burn rate of zero to three decimals; 7.5% rank higher.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

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.

Expected shaking damage in Deer Ridge: $0.023 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
0.8 times the typical $0.030: Deer Ridge’s $0.023 is ordinary.
Shaking damage a year per $1,000 of building value
Earthquake risk in Alberta peaks in Black Diamond ($0.048); Deer Ridge, at $0.023, sits above the median of $0.013.

Get ready for what Deer Ridge faces
What to do about the hazards Deer Ridge 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
- 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 Deer Ridge.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Deer Ridge’s included.
- 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 Deer Ridge.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Deer Ridge is its health region’s, the survey’s design unit.
