Fire is a regular visitor: 24% of the land within 25 km of Central Okanagan West has burned since 1986 (0.62% a year). Earthquakes matter little: NRCan’s model puts building losses at $0.014 a year per $1,000 of value, against $0.030 for the typical town. In Health Canada’s survey, 17% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Hazard risk gives Central Okanagan West a grade of D−; its wildfire band pulls it down.

Central Okanagan West grades D− for hazard risk
Earthquake risk and radon make Central Okanagan West’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #251 of 254 in British Columbia and #2,576 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.
26% of the land near Central Okanagan West’s homes has burned since 1986, 24% within 25 km
Fires mapped since 1986 around where Central Okanagan West’s residents live, and the fuel next to their homes.
The yearly burn rate around Central Okanagan West is 0.62%, against 0.000% for the typical Canadian town: the high band.
Forest crowds in on Central Okanagan West: 59% of the land within 5 km is forest fuel, more than the 51% within 25 km.

Towns with a flood study on file
Central Okanagan West is one of the 76% of towns in British Columbia with a flood study on file; across Canada it is 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of Central Okanagan West’s homes are at risk.
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 Central Okanagan West: $0.014 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Shaking costs the typical town $0.030 a year; in Central Okanagan West it is only $0.014, 0.5 times as much.
Shaking damage a year per $1,000 of building value
Central Okanagan West’s $0.014 sits under the median in British Columbia, $0.36, and well under Duncan’s $1.33.

Get ready for what Central Okanagan West faces
Practical steps for Central Okanagan West’s hazards, most pressing first.
- 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?
- Check the address on the flood map.
- How close is the forest edge?
- Are flood and wildfire insured?
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, Central Okanagan West’s included.
- 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 Central Okanagan West sits in.
- 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 Central Okanagan West floods.
- 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 Central Okanagan West.
