Since 1986 almost nothing has burned near Saint-Quentin: 0% of the land within 25 km, or 0.001% a year. Earthquakes add more: NRCan’s model puts building losses at $0.076 a year per $1,000 of value, against $0.030 for the typical town. More homes than usual carry radon here, 29% over the guideline where the typical town has 6.6%. Saint-Quentin grades D for hazard risk; wildfire is low here, so it earns no credit.

Hazard risk in Saint-Quentin: D
The grade weighs Saint-Quentin’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.

There is no study for Saint-Quentin on the national flood inventory, which is far from complete.
Towns with a flood study on file
Flood maps are common in New Brunswick, 93% of towns against 58% nationally, but none in the inventory touches Saint-Quentin.

Flood mapping is shown for Saint-Quentin to be opened and checked, never turned into a grade.
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 Saint-Quentin faces
What to do about the hazards Saint-Quentin 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.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
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, Saint-Quentin 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 Saint-Quentin.
- Wildfire counts one way. For Saint-Quentin, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Saint-Quentin’s census subdivision (a neighbourhood shows its city’s).
Questions about flooding and hazards in Saint-Quentin
Is radon a problem in Saint-Quentin?
In Health Canada’s survey, 29% of 86 homes tested in Saint-Quentin’s area were above 200 Bq/m³, though only a test tells you about one house.
