Little of the land around Anniedale has burned: 0.1% within 25 km since 1986, or 0.003% a year. In Health Canada’s survey, just 0% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Hazard risk gives Anniedale a grade of B; its wildfire band pulls it down.
What stands out about Anniedale’s hazards
For Anniedale, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Hazard risk in Anniedale: B
The grade weighs Anniedale’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #59 of 254 in British Columbia and #1,520 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The radon share rests on 70 home tests in the survey area, so a few homes move it. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around Anniedale has burned: 0% within 5 km, 0.1% within 25 km since 1986
Fires mapped since 1986 around where Anniedale’s residents live, and the fuel next to their homes.
Forty years of fire maps put Anniedale at 0.003% a year, low next to the typical Canadian town’s 0.000%.
Since 1986 the nearest fire to Anniedale’s homes came within 13 km, never inside 5 km.
27% of the land within 25 km of Anniedale is forest fuel, yet only 1.8% within 5 km of its homes.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).
Burn rate a year, towns in British Columbia · highest of 255
Some fire is mapped around Anniedale (0.003% a year), but it ranks only 191st of 255 towns in British Columbia; Oliver has 0.98%.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
7.5% of Canada’s 2,610 towns burn fast enough to rank moderate or above; Anniedale stays low, with 92%.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Listed, not scored: a flood study proves a map exists, not that Anniedale floods.
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.

Shaking is Anniedale’s costliest hazard: $0.47 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.
At $0.47 per $1,000, Anniedale carries roughly 15.7 times the typical Canadian town’s earthquake risk ($0.030).
Anniedale doesn’t get its own earthquake risk figures; the ones here come from the city of Surrey.

Get ready for what Anniedale faces
What to do about the hazards Anniedale faces, and what to ask before you buy.
- 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.
- Drop, cover and hold on.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Check the address on the flood map.
- Are flood and wildfire insured?
- Is earthquake cover included?
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 Anniedale 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 Anniedale’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 Anniedale until then.
- Wildfire counts one way. For Anniedale, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
