Electoral Area J, Central Kootenay grades C+ for hazard risk
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Electoral Area J, Central Kootenay with little fire nearby would get no credit for it.
Its place: #201 of 254 in British Columbia and #1,837 of 2,589 Canadian towns.
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.

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 Electoral Area J, Central Kootenay without grading them.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Electoral Area J, Central Kootenay’s census subdivision (a neighbourhood shows its city’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 Electoral Area J, Central Kootenay until then.
- Wildfire counts one way. For Electoral Area J, Central Kootenay, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
