Fire seldom reaches Pleasant Hill: since 1986, 0.6% of the land within 25 km has burned (0.01% a year). Shaking is less of a worry than in most places, at $0.006 a year per $1,000 of building value ($0.030 typical). Pleasant Hill’s survey area, 6.6% over the radon guideline, is close to the typical town’s 6.6%. Pleasant Hill grades A for hazard risk, with wildfire counted against it.

Pleasant Hill grades A for hazard risk
Earthquake risk and radon make Pleasant Hill’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #9 of 104 in Saskatchewan and #299 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 76 home tests in the survey area, so a few homes move it. Small fires and grass fires are largely missing from the national burned-area record.
Few fires near Pleasant Hill: 0% within 5 km, 0.6% within 25 km
Past fire around Pleasant Hill’s homes, from the national burned-area record, with the fuel within 5 km.
The land within 25 km of Pleasant Hill burns at 0.01% a year on average, the low band; the typical Canadian town: 0.000%.
Fire has stayed at least 21 km from Pleasant Hill’s homes since 1986.
With 0% forest fuel within 5 km and 0% within 25 km, the land around Pleasant Hill gives a fire little to burn.

Flood mapping is shown for Pleasant Hill to be opened and checked, never turned into a grade.
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.

Some radon around Pleasant Hill: 6.6% of area homes over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
The survey area of Pleasant Hill reads 6.6%, a shade from the typical Canadian town’s 6.6%. Nobody publishes radon tests for Pleasant Hill alone, so this card uses the figure for the Saskatoon RHA.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Against the typical town in Saskatchewan (9.1%), the area around Pleasant Hill has fewer high tests: 6.6%.

Radon tops the guideline in a modest share of homes around Pleasant Hill, a band holding 37% of Canada’s 2,611 towns; 26% rank above.
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.
One home in Pleasant Hill can be high while next door is low; a three-month test settles it.

Get ready for what Pleasant Hill faces
Practical steps for Pleasant 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
- 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 Pleasant Hill.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Pleasant Hill’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Pleasant Hill’s figure is its subdivision’s.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Pleasant Hill is its health region’s, the survey’s design unit.
Questions about flooding and hazards in Pleasant Hill
Does Pleasant Hill flood?
There is flood mapping for Pleasant Hill on the national inventory, each study linked to its owner’s map, none of them graded.
Is Pleasant Hill at risk of wildfire?
Some, but Pleasant Hill’s low band (0.6% of nearby land burned since 1986, latest 2023) is short of the level that counts.
How is Pleasant Hill’s Hazard risk Grade worked out?
Hazard risk gives Pleasant Hill A, weighing earthquakes and radon and counting wildfire only against it.
How big is the earthquake risk in Pleasant Hill?
NRCan’s model expects shaking to cost buildings in Pleasant Hill $0.006 a year for every $1,000 of their value, on average over many years.
Is radon a problem in Pleasant Hill?
The area’s survey found 6.6% of 76 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Pleasant Hill.
