Burn scars are few around Warner County No. 5, with 0.8% of the land within 25 km touched by fire since 1986 (0.02% a year). Shaking is about as much of a worry in Warner County No. 5 as in most places, at $0.022 a year per $1,000 of building value ($0.030 typical). About as many homes carry radon around Warner County No. 5 as elsewhere, 8.9% over the guideline where the typical town has 6.6%. Hazard risk gives Warner County No. 5 a grade of B; its wildfire band pulls it down.
What stands out about Warner County No. 5’s hazards
Four national sources, each read for Warner County No. 5: earthquakes, radon, past fires and flood studies.

Warner County No. 5 grades B for hazard risk
The grade weighs Warner County No. 5’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #446 of 474 in Alberta and #1,459 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.
Few fires near Warner County No. 5: 0% within 5 km, 0.8% within 25 km
Past fire around Warner County No. 5’s homes, from the national burned-area record, with the fuel within 5 km.

Towns with a flood study on file
Flood maps are thinner in Alberta, 46% of towns against 58% nationally, but Warner County No. 5 has one.

Flood mapping is shown for Warner County No. 5 to be opened and checked, never turned into a grade.
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 Warner County No. 5 faces
What to do about the hazards Warner County No. 5 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.

- 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; Warner County No. 5’s figure is its subdivision’s.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Warner County No. 5 takes its 2007 health region’s share.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Warner County No. 5.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Warner County No. 5’s homes since 1986, a history of fire that may lower Risk but never raises it.
