Radon is Devon 30’s main hazard: 17% of tested homes in its area top Health Canada’s guideline
Fire seldom reaches Devon 30: since 1986, 0.1% of the land within 25 km has burned (0.002% a year). Earthquake risk in Devon 30 is ordinary: NRCan’s model puts building losses at $0.030 a year per $1,000 of value, close to the typical town’s $0.030. Devon 30 grades C for hazard risk; wildfire is low here, so it earns no credit.

Hazard risk in Devon 30: C
For Devon 30, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
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.
Little of the land around Devon 30 has burned: 0% within 5 km, 0.1% within 25 km since 1986

Devon 30 is on the flood map inventory: 1 study, by Service New Brunswick - GeoNB
Flood studies whose area touches Devon 30, from NRCan’s inventory, each linked to its owner.
One study on the inventory touches Devon 30, Service New Brunswick - GeoNB’s from 2020, and its area can be large, so it says a map exists, not that the town floods.

Towns with a flood study on file
Its flood study puts Devon 30 with 93% of towns in New Brunswick; Canada’s share is 58%.
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 Devon 30’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.”

Get ready for what Devon 30 faces
Practical steps for Devon 30’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.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Check the address on the flood map.
- Are flood and wildfire insured?
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 Devon 30 is its health region’s, the survey’s design unit.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Devon 30’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 Devon 30.
- 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 Devon 30’s.

Does Devon 30 flood?
There is flood mapping for Devon 30 on the national inventory, each study linked to its owner’s map, none of them graded.
