Whilst I'm not going to apologise for Apple's building designers, last time I was in Chicago (March '17) I couldn't walk half a block without tripping over a "watch for falling ice" sign. So it seems very few people can design for snow in Chicago. Is this a local problem, or are these "falling ice" signs common throughout all snowy US cities?

(I'm a UK resident, we handle snow by bringing the country to a standstill for 48 hours and complaining a lot...)

Yeah, this is a much harder problem to solve than most people realize, particularly in areas that see a lot of snow. In Stockholm you see these signs as well, and in fact on winters with a lot of snow you’ll see people literally shoving snow off the top of buildings in order to minimize dangers and reduce weight on the rooftops.
