Evansdale faces fewer hazards than 98% of Canadian towns
No wildfire is mapped within 25 km of Evansdale’s homes since 1986 (0% of the land, 0.000% a year). Shaking is less of a worry than in most places, at $0.013 a year per $1,000 of building value ($0.030 typical). Fewer homes than usual carry radon here, 1.4% over the guideline where the typical town has 6.6%. Evansdale grades A+ for hazard risk, with wildfire counted against it.

Evansdale grades A+ for hazard risk
Earthquake risk and radon make Evansdale’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #11 of 474 in Alberta and #22 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 73 homes were tested in the survey area, so the radon share is rough. Small fires and grass fires are largely missing from the national burned-area record.
Little of the land around Evansdale has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Evansdale’s residents live, and the fuel next to their homes.
Low: the land around Evansdale burns at 0.000% a year, where the typical Canadian town sees 0.000%.
With 0% forest fuel within 5 km and 0.3% within 25 km, the land around Evansdale gives a fire little to burn.

The flood map inventory lists nothing for Evansdale
Flood studies whose area touches Evansdale, from NRCan’s inventory, each linked to its owner.
The inventory has nothing for Evansdale, but a local or conservation-authority map may still exist.
Towns with a flood study on file
Flood maps are thinner in Alberta, 46% of towns against 58% nationally, and Evansdale has none.

Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Evansdale.
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. For the official version of a map, updated information, or confirmation of applicable regulations, please contact the local authority responsible for flood mapping.”
Earthquakes cost buildings in Evansdale just $0.013 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
At $0.013 per $1,000, Evansdale carries 0.4 times the typical Canadian town’s earthquake risk ($0.030): low.
Shaking damage a year per $1,000 of building value
Typical for its province: Evansdale at $0.013 beside a median in Alberta of $0.013, with Black Diamond on top at $0.048.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Most of Canada’s 2,611 towns (75%) face more earthquake damage than Evansdale.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
The loss is to Evansdale’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Get ready for what Evansdale faces
Practical steps for Evansdale’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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Evansdale’s.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Evansdale sits in.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Evansdale floods.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Evansdale’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
Questions about flooding and hazards in Evansdale
How is Evansdale’s Hazard risk Grade worked out?
Hazard risk gives Evansdale A+, weighing earthquakes and radon and counting wildfire only against it.
Does Evansdale flood?
No study on Canada’s Flood Map Inventory covers Evansdale (0), which doesn’t mean it has never been mapped, so ask the municipality.
How big is the earthquake risk in Evansdale?
About $0.013 a year per $1,000 of building value, NRCan’s long-run expectation for Evansdale.
Is Evansdale at risk of wildfire?
Very little by the national record: Evansdale’s band is low, with 0% of the land within 25 km burned since 1986, so wildfire doesn’t change its grade.
Is radon a problem in Evansdale?
1.4% of the 73 homes Health Canada tested around Evansdale topped the guideline; your own house needs its own test.
