The Washington DC city council approved an ordinance which includes a fine for residents and businesses who do not shovel the snow in front of their properties. Frankly, I've always found it odd that people with homes fronted by a public sidewalk did not clear their walks and even more surprising have been local business which did not do this.
Often the reason for neglecting the shoveling stems from the belief that there is a law somewhere which states that if you don't shovel the walk and someone falls, you aren't liable because the snow is an act of nature. But if you do shovel and don't get it completely cleared and someone falls you are liable because you've messed with nature.
A couple of years ago I did some checking and found that theory to be wrong, there is no law about shoveling or not shoveling. It's just the right thing to do if you are at all physically able. Oddly, the Clayton neighborhood we're in has many more homes who do not shovel than do and is also an area where people walk frequently. Grade school kids go to and fro from grade school and middle school, Wash U students walk through to get to Kaldi's, people with dogs have to get them out. So when snow hits, forget about walking safely.
This ordinance may be difficult to enforce fairly. Officials will have to get a complaint or actually see an issue. Some will be fined others won't.
