What this data can and can’t tell you
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Lac La Hache 220’s census subdivision (a neighbourhood shows its city’s).
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Lac La Hache 220 without grading them.
- 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 Lac La Hache 220 until then.
- Wildfire counts one way. For Lac La Hache 220, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
