Around Warfield, 29% of tested homes have radon above the guideline
Fire reaches the land around Warfield now and then: 2.1% within 25 km since 1986 (0.05% a year), below the high band. Seismic risk runs low: $0.011 of expected damage per $1,000 of buildings a year, the typical town $0.030. Hazard risk gives Warfield a grade of C+; its wildfire band pulls it down.

Hazard risk in Warfield: C+
The grade weighs Warfield’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.

The flood map inventory lists nothing for Warfield
What Canada’s Flood Map Inventory lists for Warfield: who studied flooding and where to see their maps.
The inventory has nothing for Warfield, but a local or conservation-authority map may still exist.
Towns with a flood study on file
Warfield has no flood study on file, though 76% of towns in British Columbia do (Canada: 58%).
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 Warfield.
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.”
Little shaking expected in Warfield: $0.011 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Warfield’s $0.011 is a fraction of the typical town’s $0.030 (0.4 times as much): quiet ground by Canadian standards.
Shaking damage a year per $1,000 of building value

Get ready for what Warfield faces
What to do about the hazards Warfield faces, and what to ask before you buy.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- 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.
- Has it had a radon test?
- Ask the municipality for flood maps.
- How close is the forest edge?
- Are flood and wildfire insured?
What this data can and can’t tell you
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Warfield without grading them.
- Wildfire counts one way. For Warfield, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- 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 Warfield until then.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Warfield’s census subdivision (a neighbourhood shows its city’s).
