A flood study covers Sage Hill: 1 on the national inventory, the newest from Government of Alberta
Wildfire barely registers for Sage Hill, at 0% of the land within 25 km since 1986 (0.000% a year). For earthquakes Sage Hill is middling, $0.023 a year per $1,000 against $0.030 for the typical town. Radon around Sage Hill is ordinary for Canada: 8.1% of tested homes over the guideline (6.6% typical). Hazard risk gives Sage Hill a grade of B+, from earthquakes and radon alone.

Hazard risk in Sage Hill: B+
For Sage Hill, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
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 Sage Hill: 0% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where Sage Hill’s residents live, and the fuel next to their homes.
Sage Hill burns at 0.000% a year, low against 0.000% for the typical Canadian town.
The 5 km ring around Sage Hill’s homes is clear of burns since 1986, the nearest 10 km out.
Forest makes up 0% of the land within 5 km of Sage Hill and 0.6% 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).

Towns with a flood study on file
Only 46% of towns in Alberta have a flood study, short of Canada’s 58%; Sage Hill is one of them.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood studies don’t enter the grade; they are listed so you can open the official map for Sage Hill.
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 Sage Hill $0.023 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.
With $0.023 of shaking damage a year per $1,000, Sage Hill is about even with the typical $0.030 (0.8 times).
Shaking damage a year per $1,000 of building value
Above the middle in Alberta: Sage Hill’s $0.023 against a median of $0.013, with Black Diamond highest 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.
Neither high nor low for Canada: 54% of the 2,611 towns expect more damage than Sage Hill.
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 Sage Hill’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Get ready for what Sage Hill faces
Practical steps for Sage Hill’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; Sage Hill’s figure is its subdivision’s.
- 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 Sage Hill until then.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Sage Hill’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Sage Hill without grading them.
Questions about flooding and hazards in Sage Hill
How is Sage Hill’s Hazard risk Grade worked out?
Sage Hill’s Hazard risk grade is B+, built on earthquakes and radon with a one-sided wildfire input.
Does Sage Hill flood?
A flood study covers Sage Hill on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
How big is the earthquake risk in Sage Hill?
Expected earthquake damage in Sage Hill comes to $0.023 a year for each $1,000 that buildings are worth.
Is Sage Hill at risk of wildfire?
Not much by Canadian standards: Sage Hill’s band is low, with 0% of the land within 25 km burned since 1986 (last in 2017), so wildfire doesn’t change its grade.
Is radon a problem in Sage Hill?
8.1% of the 86 homes Health Canada tested around Sage Hill topped the guideline; your own house needs its own test.
