Hazard risk in Suder Greens is lower than in 98% of Canadian towns
Since 1986 almost nothing has burned near Suder Greens: 0% of the land within 25 km, or 0.000% a year. Earthquakes matter little: NRCan’s model puts building losses at $0.013 a year per $1,000 of value, against $0.030 for the typical town. Radon is lower than usual: 1.4% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Suder Greens grades A+ for hazard risk, with wildfire counted against it.

Suder Greens grades A+ for hazard risk
The grade weighs Suder Greens’ seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #11 of 474 in Alberta and #22 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 73 home tests in the survey area, so a few homes move it. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Few fires near Suder Greens: 0% within 5 km, 0% within 25 km

Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Suder Greens.
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 Suder Greens faces
What to do about the hazards Suder Greens 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
- Wildfire counts one way. For Suder Greens, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- 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 Suder Greens.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Suder Greens’ census subdivision (a neighbourhood shows its city’s).
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Suder Greens is its health region’s, the survey’s design unit.
