Should they move the houses in Gatineau that were evacuated? No, or at least not before checking for leda clay.
There’s a group of houses in Gatineau that were built at the foot of a hill where they shouldn’t have been built. Somehow the builder(s) obtained permission where it now appears older geologic assessment reports said nothing should be built. Hydro workers inspecting something at the top of the hill noticed a large crack in the ground and alerted the province who immediately ordered the evacuation of the homes. Since then it’s been determined that they can’t ever be reoccupied.
Hindsight is 20-20, isn’t it?
So, the home owners who bought the houses in good faith are now faced with the prospect of losing their homes. The Quebec government is offering up to $100,000 in compensation. The City of Gatineau is offering an additional $75,000, but only if the owners agree to give up their right to sue. (For reference, at least one of the homes was reportedly worth almost twice that total amount.)
Basically, the home owners are screwed because someone didn’t pay attention to a map that said “don’t build here” or something similar.
CBC reported on Thursday that the City is looking for lots that the houses can be moved to. Now, moving a building is a non-trivial task that can costs thousands of dollars.
I haven’t seen an in-depth discussion of the geology in that area in any of the reports, but chances are it’s similar to what’s found on the Ontario side of the Ottawa River: leda clay.
