A flood study covers Nolan Hill: 1 on the national inventory, the newest from Government of Alberta
For Nolan Hill, wildfire history is close to nil: 0% of nearby land since 1986, 0.000% a year. NRCan expects $0.023 of shaking damage a year per $1,000 of buildings in Nolan Hill, near the typical $0.030. Nolan Hill’s survey area, 8.1% over the radon guideline, is close to the typical town’s 6.6%. Nolan Hill grades B+ for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Nolan Hill’s hazards
Four national sources, each read for Nolan Hill: earthquakes, radon, past fires and flood studies.
What Nolan Hill faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.
Wildfire
Earthquakes
Radon
Flood study
Hazard risk in Nolan Hill: B+
Earthquake risk and radon make Nolan Hill’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #282 of 474 in Alberta and #1,102 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Small fires and grass fires are largely missing from the national burned-area record.
Wildfire is rare near Nolan Hill: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Nolan Hill’s homes, from the national burned-area record, with the fuel within 5 km.
The yearly burn rate around Nolan Hill is 0.000%, low beside 0.000% for the typical Canadian town.
The closest burn since 1986 lies 9.5 km from Nolan Hill’s homes, none within 5 km.
Forest fuel is scarce around Nolan Hill: 0.1% of the land within 5 km, 0.6% within 25 km.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).
Burn rate a year, towns in Alberta · highest of 478
Of the 478 towns in Alberta, 386 have a burn rate that rounds to zero, Nolan Hill among them; Wainwright leads at 1.43% a year.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
Measured against 2,610 towns, Nolan Hill is in the largest group, low (92%), and at its floor, while 7.5% rank higher.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Towns with a flood study on file
Flood maps are thinner in Alberta, 46% of towns against 58% nationally, but Nolan Hill has one.

Listed, not scored: a flood study proves a map exists, not that Nolan Hill floods.
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.”

Ordinary seismic risk in Nolan Hill: $0.023 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Nolan Hill’s $0.023 is close to the typical town’s $0.030 (0.8 times as much).
For earthquake risk, the only official count covers all of the city of Calgary, Nolan Hill included.
Shaking damage a year per $1,000 of building value
Nolan Hill’s $0.023 tops the median in Alberta, $0.013, though Black Diamond reaches $0.048.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Nolan Hill sits mid-range among Canada’s 2,611 towns: 54% expect more shaking damage.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
The loss is to Nolan Hill’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Radon about average around Nolan Hill: 8.1% over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
Around Nolan Hill, 8.1% of tested homes topped the guideline, near the typical Canadian town’s 6.6%. Nobody publishes radon tests for Nolan Hill alone, so this card uses the figure for the Calgary Health Region.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
The typical town in Alberta has 7.5% over 200 Bq/m³; Nolan Hill’s area has 8.1%, much the same.
Health Canada radon survey (2009–2011), by 2007 health region; medians of towns of 2,500 people or more.
Between 5% and 10% of tests over the guideline: Nolan Hill, and 37% of Canada’s 2,611 towns; 26% are higher.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
A survey sample isn’t a map: any home in Nolan Hill can be high, and a three-month test is the only way to know.

Get ready for what Nolan Hill faces
Practical steps for Nolan Hill’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?
- Check the address on the flood map.
- Are flood and wildfire insured?
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 Nolan Hill’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Nolan Hill 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 Nolan Hill until then.
- 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 Nolan Hill’s.
Questions about flooding and hazards in Nolan Hill
How is Nolan Hill’s Hazard risk Grade worked out?
Nolan Hill’s Hazard risk grade is B+, built on earthquakes and radon with a one-sided wildfire input.
Is radon a problem in Nolan Hill?
The area’s survey found 8.1% of 86 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Nolan Hill.
How big is the earthquake risk in Nolan Hill?
NRCan’s model expects shaking to cost buildings in Nolan Hill $0.023 a year for every $1,000 of their value, on average over many years.
Is Nolan Hill at risk of wildfire?
Some, but Nolan Hill’s low band (0% of nearby land burned since 1986, latest 2018) is short of the level that counts.
Does Nolan Hill flood?
