What this data can and can’t tell you
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Carson Grove - Carson Meadows.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Carson Grove - Carson Meadows takes its 2007 health region’s share.
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Carson Grove - Carson Meadows’.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Carson Grove - Carson Meadows’ homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
