I don't know about other cities in North America but heated sidewalks would work only for a very small area in the city I live in and is covered by at provincial, federal and each municipalities jurisdiction. The entire are that would need to be done to stop snow ploughs being needed is almost 100 square kilometers. Most of the city is laid out in a fairly spread out way almost entirely the opposite of the European cities and small American towns used in the example. The cost to implement a heated road and sidewalk system here would be ridiculous and the city already seems to leave their roads more unmaintained than they should anyway. I just don't see such a system of water heated roads being feasible in North America not the the parts of it I've seen have been designed, without drastically rebuilding most cities. Not to mention we get a lot of snow and already have flooding problems in the city when there's heavy rain or big snow melts. This just changes things to a different problem.
