The national fire record shows next to nothing around Sainte-Clotilde-de-Horton, 0% of the land within 25 km since 1986 (0.001% a year). Earthquakes add more: NRCan’s model puts building losses at $0.11 a year per $1,000 of value, against $0.030 for the typical town. Fewer homes than usual carry radon here, 0% over the guideline where the typical town has 6.6%. Hazard risk gives Sainte-Clotilde-de-Horton a grade of B+; its wildfire band pulls it down.

Hazard risk in Sainte-Clotilde-de-Horton: B+
Two inputs always count for Sainte-Clotilde-de-Horton, earthquakes and radon; the third, wildfire, counts only against a town.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The radon share rests on 58 home tests in the survey area, so a few homes move it. Small fires and grass fires are largely missing from the national burned-area record.

Towns with a flood study on file
Sainte-Clotilde-de-Horton is one of the 45% of towns in Quebec with a flood study on file, fewer than Canada’s 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Listed, not scored: a flood study proves a map exists, not that Sainte-Clotilde-de-Horton 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.”

Get ready for what Sainte-Clotilde-de-Horton faces
What to do about the hazards Sainte-Clotilde-de-Horton 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
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Sainte-Clotilde-de-Horton takes its 2007 health region’s share.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Sainte-Clotilde-de-Horton’s figure is its subdivision’s.
- 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 Sainte-Clotilde-de-Horton.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Sainte-Clotilde-de-Horton’s homes since 1986, a history of fire that may lower Risk but never raises it.
