Hazards in Munroe West: wildfire low, radon over the guideline in 12% of tested homes
Fire has left almost no mark near Munroe West: 0% of the land within 25 km since 1986, 0.001% a year. Earthquakes matter little: NRCan’s model puts building losses at $0.006 a year per $1,000 of value, against $0.030 for the typical town. Munroe West grades B+ for hazard risk, with wildfire counted against it.

Munroe West grades B+ for hazard risk
Two inputs always count for Munroe West, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #10 of 185 in Manitoba and #940 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The radon share rests on 66 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.
Few fires near Munroe West: 0% within 5 km, 0% within 25 km

No flood study is listed for Munroe West
What Canada’s Flood Map Inventory lists for Munroe West: who studied flooding and where to see their maps.
No flood study on the national inventory covers Munroe West; ask the municipality, which is the authority for its flood maps.
Towns with a flood study on file
Mapping in Manitoba reaches 18% of towns, below the 58% across Canada, and not Munroe West.
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 Munroe West’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 Munroe West faces
What to do about the hazards Munroe West faces, and what to ask before you buy.
- 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
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Munroe West’s figure is its subdivision’s.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Munroe West is its health region’s, the survey’s design unit.
- 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 Munroe West.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Munroe West’s homes since 1986, a history of fire that may lower Risk but never raises it.
