Little of the land around Division No. 7, Subdivision L has burned: 0% within 25 km since 1986, or 0.000% a year. Seismic risk runs low: $0.009 of expected damage per $1,000 of buildings a year, the typical town $0.030. In Health Canada’s survey, just 4% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Division No. 7, Subdivision L grades A+ for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Division No. 7, Subdivision L’s hazards
For Division No. 7, Subdivision L, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Division No. 7, Subdivision L faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.
Wildfire

Division No. 7, Subdivision L grades A+ for hazard risk
Earthquake risk and radon make Division No. 7, Subdivision L’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
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 Division No. 7, Subdivision L: 0% of the land within 25 km burned since 1986, 0.1% within 5 km

Towns with a flood study on file
Flood maps are common in Newfoundland and Labrador: 59% of towns have one, against 58% nationally, and Division No. 7, Subdivision L is among them.

Flood is shown here, never graded: a study says where a map exists, not how many of Division No. 7, Subdivision L’s homes stand in a flood zone.
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 Division No. 7, Subdivision L faces
Practical steps for Division No. 7, Subdivision L’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
- 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 Division No. 7, Subdivision L floods.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Division No. 7, Subdivision L’s census subdivision (a neighbourhood shows its city’s).
- 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 Division No. 7, Subdivision L sits in.
- Wildfire counts one way. For Division No. 7, Subdivision L, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
Questions about flooding and hazards in Division No. 7, Subdivision L
How is Division No. 7, Subdivision L’s Hazard risk Grade worked out?
Division No. 7, Subdivision L’s Hazard risk grade is A+, built on earthquakes and radon with a one-sided wildfire input.
Is Division No. 7, Subdivision L at risk of wildfire?
Some, but Division No. 7, Subdivision L’s low band (0% of nearby land burned since 1986, latest 2025) is short of the level that counts.
Is radon a problem in Division No. 7, Subdivision L?
The area’s survey found 4% of 100 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Division No. 7, Subdivision L.
Does Division No. 7, Subdivision L flood?
Division No. 7, Subdivision L’s area has been studied for flooding, and the owner’s map shows which streets lie in a zone; the grade leaves flood out.
How big is the earthquake risk in Division No. 7, Subdivision L?
In NRCan’s seismic model, Division No. 7, Subdivision L’s buildings lose $0.009 per $1,000 of value in an average year.
