Photo: 36reasons · Public domainWest Kelowna faces more hazards than 98% of Canadian towns
Wildfire is a real hazard for West Kelowna: 20% of the land within 25 km has burned since 1986, 0.52% a year, in the high band. Seismic risk runs low: $0.015 of expected damage per $1,000 of buildings a year, the typical town $0.030. More homes than usual carry radon here, 17% over the guideline where the typical town has 6.6%. West Kelowna grades D− for hazard risk, with wildfire counted against it.

West Kelowna grades D− for hazard risk
Two inputs always count for West Kelowna, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #248 of 254 in British Columbia and #2,573 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.

Flooding around West Kelowna is mapped in 2 studies, the newest by Okanagan Basin Water Board
Flood studies whose area touches West Kelowna, from NRCan’s inventory, each linked to its owner.
2 studies on the inventory touch West Kelowna, the newest Okanagan Basin Water Board’s from 2020, and their areas can be large, so they say maps exist, not that the town floods.

|---|---|---|---|
| Okanagan Mainstem Floodplain Mapping Project | Okanagan Basin Water Board | 2020 | final |
| Kelowna Mill Creek | City of Kelowna | 2010 | final |
Towns with a flood study on file
Flood maps are common in British Columbia: 76% of towns have one, against 58% nationally, and West Kelowna is among them.

No single decade dominates: 2 studies for West Kelowna between the 2010s and the 2020s.
Study dates as the NRCan inventory lists them, one count per study touching West Kelowna.
Flood studies don’t enter the grade; they are listed so you can open the official map for West Kelowna.
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.”

Earthquakes cost buildings in West Kelowna just $0.015 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
West Kelowna’s $0.015 is a fraction of the typical town’s $0.030 (0.5 times as much): quiet ground by Canadian standards.
Shaking damage a year per $1,000 of building value
The typical town in British Columbia expects $0.36 a year in shaking damage; West Kelowna expects less, $0.015, and Duncan the most, $1.33.

Earthquakes cost less around West Kelowna than in 72% of Canada’s 2,611 towns.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
The loss is to West Kelowna’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Test for radon in West Kelowna: 17% of area homes were over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Source area for radon tests: the Okanagan health region
West Kelowna’s area, at 17%, is above the 6.6% of the typical Canadian town, so testing is worth more here than most places.

Get ready for what West Kelowna faces
What to do about the hazards West Kelowna 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?
- 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
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of West Kelowna’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for West Kelowna.
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as West Kelowna’s.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for West Kelowna is its health region’s, the survey’s design unit.
