Some 2.8% of the land within 25 km of Golden has burned since 1986; at 0.07% a year that is moderate, not high. Earthquake risk in Golden is ordinary: NRCan’s model puts building losses at $0.044 a year per $1,000 of value, close to the typical town’s $0.030. Golden grades C− for hazard risk, with wildfire counted against it.
What stands out about Golden’s hazards
Four national sources, each read for Golden: earthquakes, radon, past fires and flood studies.

Hazard risk in Golden: C−
Two inputs always count for Golden, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #225 of 254 in British Columbia and #2,410 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.
Fire reaches the land around Golden: 0% within 5 km, 2.8% within 25 km
Past fire around Golden’s homes, from the national burned-area record, with the fuel within 5 km.
The yearly burn rate around Golden is 0.07%, above 0.000% for the typical Canadian town but under the high band.
Nothing inside 5 km of Golden’s homes has burned since 1986, and the nearest scar is 7.3 km off.
Forest fuel is denser close to Golden (74% within 5 km) than further out (55% within 25 km).

Burn rate a year, towns in British Columbia · highest of 255
The land around Golden burns at 0.07% a year, the 62nd highest rate of 255 towns in British Columbia; Oliver tops it at 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.
Moderate puts Golden above most of Canada’s 2,610 towns, yet 2.1% rank high or very high and 5.4% share its band.
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.

Towns with a flood study on file
Golden 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 2 studies touching Golden are spread over time, from the 1970s to the 2020s.
Study dates as the NRCan inventory lists them, one count per study touching Golden.
Listed, not scored: a flood study proves a map exists, not that Golden 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. For the official version of a map, updated information, or confirmation of applicable regulations, please contact the local authority responsible for flood mapping.”

Ordinary seismic risk in Golden: $0.044 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Earthquake losses in Golden, $0.044 per $1,000, are in line with the typical $0.030 (1.5 times).
Shaking damage a year per $1,000 of building value
Below the middle in British Columbia: Golden’s $0.044 against a median of $0.36; Duncan has $1.33.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Golden sits above most of Canada’s 2,611 towns on earthquake risk; 32% are higher.
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 model counts damage to Golden’s buildings and their occupants from shaking only: not liquefaction, landslides, tsunami or fires after a quake.

Get ready for what Golden faces
What to do about the hazards Golden 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
- 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 Golden’s.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Golden takes its 2007 health region’s share.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Golden.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Golden’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
Questions about flooding and hazards in Golden
How big is the earthquake risk in Golden?
NRCan’s model expects shaking to cost buildings in Golden $0.044 a year for every $1,000 of their value, on average over many years.
Is Golden at risk of wildfire?
Less than most of Canada: 2.8% of the land within 25 km of Golden has burned since 1986, the last in 2025, a moderate band that leaves Risk alone.
Is radon a problem in Golden?
In Health Canada’s survey, 19% of 105 homes tested in Golden’s area were above 200 Bq/m³, though only a test tells you about one house.
How is Golden’s Hazard risk Grade worked out?
Golden grades C− for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
Does Golden flood?
The inventory lists a study touching Golden; whether a given street floods is on that map, not in the grade.
