Normanhurst is on Canada’s flood inventory: 1 listed, led by Hamilton Conservation Authority
Since 1986 almost nothing has burned near Normanhurst: 0% of the land within 25 km, or 0.000% a year. Earthquake risk in Normanhurst is ordinary: NRCan’s model puts building losses at $0.044 a year per $1,000 of value, close to the typical town’s $0.030. Radon around Normanhurst is ordinary for Canada: 5% of tested homes over the guideline (6.6% typical). Normanhurst grades B+ for hazard risk; wildfire is low here, so it earns no credit.

Normanhurst grades B+ for hazard risk
For Normanhurst, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
Its place: #494 of 866 in Ontario and #1,255 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Normanhurst: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Normanhurst’s homes, from the national burned-area record, with the fuel within 5 km.
Low by Canadian standards: 0.000% of the land a year around Normanhurst, 0.000% for the typical Canadian town.

Towns with a flood study on file
Flood maps are common in Ontario: 69% of towns have one, against 58% nationally, and Normanhurst is among them.
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 Normanhurst’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 Normanhurst faces
Practical steps for Normanhurst’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
- Wildfire counts one way. For Normanhurst, 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 Normanhurst’s census subdivision (a neighbourhood shows its city’s).
- 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 Normanhurst until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Normanhurst without grading them.
Questions about flooding and hazards in Normanhurst
Does Normanhurst flood?
A flood study covers Normanhurst on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
Is Normanhurst at risk of wildfire?
Very little by the national record: Normanhurst’s band is low, with 0% of the land within 25 km burned since 1986, so wildfire doesn’t change its grade.
How big is the earthquake risk in Normanhurst?

Is radon a problem in Normanhurst?
The area’s survey found 5% of 100 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Normanhurst.
How is Normanhurst’s Hazard risk Grade worked out?
Normanhurst’s Hazard risk grade is B+, built on earthquakes and radon with a one-sided wildfire input.
