Little of the land around Siksika 146 has burned: 0.2% within 25 km since 1986, or 0.006% a year. Seismic risk in Siksika 146 sits near the middle: $0.016 of expected damage per $1,000 of buildings a year, the typical town $0.030. In Health Canada’s survey, 8.1% of homes tested in Siksika 146’s area exceeded 200 Bq/m³, close to the typical 6.6%. Siksika 146 grades A− for hazard risk, with wildfire counted against it.

Siksika 146 grades A− for hazard risk
Seismic risk and radon set Siksika 146’s grade, wildfire can drag it down, and flood mapping stays out of it.
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.
Little of the land around Siksika 146 has burned: 0.2% within 5 km, 0.2% within 25 km since 1986
Past fire around Siksika 146’s homes, from the national burned-area record, with the fuel within 5 km.
Next to the typical Canadian town (0.000% a year), Siksika 146’s 0.006% is in the low band.
Little near Siksika 146’s homes can carry a forest fire; only 0.1% of the land within 5 km is forest fuel, and 0% within 25 km.

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 Siksika 146 faces
Practical steps for Siksika 146’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
- 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 Siksika 146 floods.
- 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 Siksika 146’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 Siksika 146 sits in.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Siksika 146’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 Siksika 146
Does Siksika 146 flood?
Siksika 146’s area has been studied for flooding, and the owner’s map shows which streets lie in a zone; the grade leaves flood out.
Is Siksika 146 at risk of wildfire?
Not much by Canadian standards: Siksika 146’s band is low, with 0.2% of the land within 25 km burned since 1986 (last in 2025), so wildfire doesn’t change its grade.
How big is the earthquake risk in Siksika 146?
NRCan’s model expects shaking to cost buildings in Siksika 146 $0.016 a year for every $1,000 of their value, on average over many years.
Is radon a problem in Siksika 146?
8.1% of the 86 homes Health Canada tested around Siksika 146 topped the guideline; your own house needs its own test.
How is Siksika 146’s Hazard risk Grade worked out?
Siksika 146’s Hazard risk grade is A−, built on earthquakes and radon with a one-sided wildfire input.
