Hazard risk in Lymburn is lower than in 98% of Canadian towns
Since 1986 almost nothing has burned near Lymburn: 0% of the land within 25 km, or 0.000% a year. Shaking is less of a worry than in most places, at $0.013 a year per $1,000 of building value ($0.030 typical). In Health Canada’s survey, just 1.4% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Lymburn grades A+ for hazard risk, with wildfire counted against it.

Lymburn grades A+ for hazard risk
For Lymburn, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
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.

No flood study is listed for Lymburn
What Canada’s Flood Map Inventory lists for Lymburn: who studied flooding and where to see their maps.
Canada’s Flood Map Inventory lists no study whose area touches Lymburn, which doesn’t mean it has never been mapped.
Towns with a flood study on file
Flood maps are thinner in Alberta, 46% of towns against 58% nationally, and Lymburn has none.
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 Lymburn’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 Lymburn faces
Practical steps for Lymburn’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
- 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 Lymburn.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Lymburn’s census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Lymburn, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Lymburn is its health region’s, the survey’s design unit.
