Wildfire is a moderate presence around Electoral Area D, Alberni-Clayoquot: 2.3% of the land within 25 km has burned since 1986, 0.06% a year, short of the band that counts against Risk. Radon is lower than usual: 0.9% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Electoral Area D, Alberni-Clayoquot a grade of B−; its wildfire band pulls it down.

Electoral Area D, Alberni-Clayoquot grades B− for hazard risk
The grade weighs Electoral Area D, Alberni-Clayoquot’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.

What this data can and can’t tell you
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Electoral Area D, Alberni-Clayoquot’s included.
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Electoral Area D, Alberni-Clayoquot.
- 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 Electoral Area D, Alberni-Clayoquot floods.
- 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 Electoral Area D, Alberni-Clayoquot sits in.
