Few places are as safe from hazards as Forest Heights: it beats 98% of Canadian towns

The burned-area map is nearly blank around Forest Heights, 0% within 25 km since 1986, 0.000% a year. Seismic risk runs low: $0.013 of expected damage per $1,000 of buildings a year, the typical town $0.030. In Health Canada’s survey, just 1.4% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Hazard risk gives Forest Heights a grade of A+; its wildfire band pulls it down.

In brief

What stands out about Forest Heights’s hazards

Four national sources, each read for Forest Heights: earthquakes, radon, past fires and flood studies.

By hazard

What Forest Heights faces

Each hazard against its own yardstick; meters run from low to high on that yardstick.

Not on this page: flood zones and homes in them, past floods, landslides, industrial sites and storm surge: Canada has no national open source for them by town.
Hazard risk Grade

Forest Heights grades A+ for hazard risk

Seismic risk and radon set Forest Heights’ grade, wildfire can drag it down, and flood mapping stays out of it.

Earthquake risk ($0.013)Better than 73% of Canadian towns
Radon (1.4%)Better than 90% of Canadian towns
Wildfire (one-sided) (Low)Better than 81% of Canadian towns · counted against it
Flood study (Yes)Shown, never graded

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. Only 73 homes were tested in the survey area, so the radon share is rough. Small fires and grass fires are largely missing from the national burned-area record.

Wildfire

Wildfire is rare near Forest Heights: 0% of the land within 25 km burned since 1986, 0% within 5 km

Practical steps for Forest Heights’ hazards, most pressing first.

Radon
  • Test for three months in winter.
  • Over 200 Bq/m³: fix it.
  • Kits are cheap; pros test too.
Take Action on Radon
When the river rises
  • Never drive through floodwater.
  • Move papers and medicines upstairs.

Alert Ready
Wildfire season
  • Clear needles and wood nearby.
  • Keep a grab-and-go bag ready.
  • In smoke, stay in; filter air.

How to read these numbers

What this data can and can’t tell you

  • Wildfire counts one way. The wildfire figure is the share of land within 25 km of Forest Heights’ homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
  • 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 Forest Heights’.
  • Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Forest Heights 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 Forest Heights.
