Obedjiwan 28 grades A+ for hazard risk
Seismic risk and radon set Obedjiwan 28’s grade, wildfire can drag it down, and flood mapping stays out of it.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. 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.

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 Obedjiwan 28 faces
Practical steps for Obedjiwan 28’s hazards, most pressing first.
- Clear needles and wood nearby.

- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Never drive through floodwater.

- How close is the forest edge?
- Are flood and wildfire insured?
What this data can and can’t tell you
- 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 Obedjiwan 28 until then.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Obedjiwan 28’s figure is its subdivision’s.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Obedjiwan 28 without grading them.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Obedjiwan 28’s homes since 1986, a history of fire that may lower Risk but never raises it.
