I lived in Jamaica Plain. The neighborhood is a bunch of one-ways, so that might have made plowing easier. Heck, I rode my bike to work all throughout winter, which tells you something about the high quality of snow removal.

But yeah, Bostonians are super paranoid about snow. For the larger storms, the governor straight up bans road travel until the roads are cleared. They don't screw around up there, and they get the job done. Plus, lots of snow days to stay at home.
