All over the country, snow is plowed leaving berms and ridges on private property. If you think that snow is hauled away in trucks throughout the nation... aren't you from a state with snowy winters? Many cities can barely afford to run plows. Detroit alone has Detroit has 1884 miles of residential streets. You think it hauls that snow away?

As for your gut feeling that governmental immunity doesn't apply, well, that and a buck will get you a cup of coffee. Can you produce even one case, from anywhere in the nation, where a municipality was held liable for any form of actionable tort by plowing snow from the street onto somebody's land?
