Wildfire is rare near Electoral Area F, Fraser Valley: 0.3% of the land within 25 km has burned since 1986, a burn rate of 0.008% a year. Shaking is a bigger worry than in most places, at $0.24 a year per $1,000 of building value ($0.030 typical). Fewer homes than usual carry radon here, 3% over the guideline where the typical town has 6.6%. Electoral Area F, Fraser Valley grades C+ for hazard risk, with wildfire counted against it.

Towns with a flood study on file
76% of towns in British Columbia have a flood study, more than Canada’s 58%; Electoral Area F, Fraser Valley has one too.
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 Electoral Area F, Fraser Valley’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.”

What this data can and can’t tell you
- Wildfire counts one way. Wildfire is read from the national burned-area record around Electoral Area F, Fraser Valley’s homes since 1986, a history of fire that may lower Risk but never raises it.
- 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 Electoral Area F, Fraser Valley until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Electoral Area F, Fraser Valley without grading them.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Electoral Area F, Fraser Valley’s figure is its subdivision’s.
