Nipissing 10 grades A− for hazard risk
Seismic risk and radon set Nipissing 10’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. Small fires and grass fires are largely missing from the national burned-area record.
Wildfire is rare near Nipissing 10: 0.4% of the land within 25 km burned since 1986, 0% within 5 km

The flood map inventory lists nothing for Nipissing 10
What Canada’s Flood Map Inventory lists for Nipissing 10: who studied flooding and where to see their maps.
Nationally, Nipissing 10 has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Missing from a well-mapped province: Nipissing 10 has no study, where 69% of towns in Ontario 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 mapping is shown for Nipissing 10 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 Nipissing 10 faces
Practical steps for Nipissing 10’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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Nipissing 10 sits in.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Nipissing 10’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Nipissing 10’s figure is its subdivision’s.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Nipissing 10 floods.
Questions about flooding and hazards in Nipissing 10
How big is the earthquake risk in Nipissing 10?
NRCan’s model expects shaking to cost buildings in Nipissing 10 $0.035 a year for every $1,000 of their value, on average over many years.
Is Nipissing 10 at risk of wildfire?
Some, but Nipissing 10’s low band (0.4% of nearby land burned since 1986, latest 1991) is short of the level that counts.
Does Nipissing 10 flood?
The inventory has 0 studies for Nipissing 10, and an empty list isn’t a clean bill: the municipality holds any flood maps.
Is radon a problem in Nipissing 10?
The area’s survey found 1.9% of 103 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Nipissing 10.
How is Nipissing 10’s Hazard risk Grade worked out?
Nipissing 10’s Hazard risk grade is A−, built on earthquakes and radon with a one-sided wildfire input.
