I have no idea what Waltham does or doesn't have. I'm just speaking from the experience of having lived in a dozen or so apartments in New England. A good attentive landlord will do a pretty good and prompt job clearing the front path and sidewalk and leave the rest to you.

It isn't worth fighting over unless you're 100% moving out at the end of your lease and don't care about a contentious relationship or whatever.

I'd expect absolutely nothing for the driveway beyond maybe a small path to a back door entrance. They're not going to help with any plow-dams at the end of the driveway and the only real promptness is that they'll probably fall within that 24-36 hr window after the storm stops when they legally have to clear it.
