Wildfire is rare near Electoral Area C, Strathcona: 0.2% of the land within 25 km has burned since 1986, a burn rate of 0.005% a year. Shaking is a bigger worry than in most places, at $0.16 a year per $1,000 of building value ($0.030 typical). Hazard risk gives Electoral Area C, Strathcona a grade of B; its wildfire band pulls it down.

Electoral Area C, Strathcona grades B for hazard risk
Seismic risk and radon set Electoral Area C, Strathcona’s grade, wildfire can drag it down, and flood mapping stays out of it.
Its place: #30 of 254 in British Columbia and #1,440 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.

No flood study is listed for Electoral Area C, Strathcona
Flood studies whose area touches Electoral Area C, Strathcona, from NRCan’s inventory, each linked to its owner.
The inventory has nothing for Electoral Area C, Strathcona, but a local or conservation-authority map may still exist.
Towns with a flood study on file
Missing from a well-mapped province: Electoral Area C, Strathcona has no study, where 76% of towns in British Columbia have one against 58% nationally.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of Electoral Area C, Strathcona’s homes stand in a flood zone.
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.”

Practical steps for Electoral Area C, Strathcona’s hazards, most pressing first.
- 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.

What this data can and can’t tell you
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Electoral Area C, Strathcona is its health region’s, the survey’s design unit.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Electoral Area C, Strathcona’s homes since 1986, a history of fire that may lower Risk but never raises it.
- 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 Electoral Area C, Strathcona.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Electoral Area C, Strathcona’s figure is its subdivision’s.
