What stands out about Coventry Hills’s hazards
Four national sources, each read for Coventry Hills: earthquakes, radon, past fires and flood studies.
What Coventry Hills faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.
Wildfire
Earthquakes
Radon
Flood study
Hazard risk in Coventry Hills: B+
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Coventry Hills 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: The seismic figure is a long-run average from NRCan’s model, not a prediction. Small fires and grass fires are largely missing from the national burned-area record.
Wildfire is rare near Coventry Hills: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Coventry Hills’ homes, from the national burned-area record, with the fuel within 5 km.
Low: the land around Coventry Hills burns at 0.000% a year, where the typical Canadian town sees 0.000%.
Nothing inside 5 km of Coventry Hills’ homes has burned since 1986, and the nearest scar is 14 km off.
Forest makes up 0% of the land within 5 km of Coventry Hills and 0.4% within 25 km, little for a forest fire to run through.
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).
Burn rate a year, towns in Alberta · highest of 478
Fire has taken almost none of the land around Coventry Hills, as for 386 of the 478 towns in Alberta; Wainwright tops the list at 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.
Only 7.5% of Canada’s 2,610 towns are above the low band, which holds 92%; Coventry Hills, at a rounded zero, is far from them.
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.

A flood study covers Coventry Hills, from Government of Alberta: 1 on the inventory
What Canada’s Flood Map Inventory lists for Coventry Hills: who studied flooding and where to see their maps.
One study on the inventory touches Coventry Hills, Government of Alberta’s from 2012, and its area can be large, so it says a map exists, not that the town floods.
| Study | By | Year | Status |
|---|---|---|---|
| Nose and West Nose Creek Flood Hazard Study | Government of Alberta | 2012 | final |
Towns with a flood study on file
Flood maps are thinner in Alberta, 46% of towns against 58% nationally, but Coventry Hills has one.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Coventry Hills.
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.”

Get ready for what Coventry Hills faces
What to do about the hazards Coventry Hills 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
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Coventry Hills’ figure is its subdivision’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 Coventry Hills sits in.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Coventry Hills’ homes since 1986, a history of fire that may lower Risk but never raises it.
- 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 Coventry Hills floods.
