A little bit of A and a little bit of B, I think.
The alluvial till in downtown Kelowna is extremely unstable, and it's the reason why Kelowna has to build floating bridges. Lots of sand and silt.
The tech is there to build large areas underground, but clearly, there are issues when it comes to managing and executing these digs.
