Some cities??? I think more accurate to say "many cities" (as far south as Sauk City). Code here says 4' depth for footings in most places, 5' in the upper north. Many places were reporting frost depths at 8-10' this year...so much for global warming around here.
That's just hard to fathom for us Southerners (I'm in MO, which isn't THAT far south). Our footings are normally 18" or so around here, and frost really doesn't make it much more than a foot in really cold winters like this past one.
