I hope you didn't have to wait too long for that to be done. The walkways here are all in the center of the building, and they keep it pretty clear. They have pails of rock salt available in the front hall for tenants to throw out on the walkway.
All the buildings have a wooden structure over the front door. When I first moved in here, the structure had a flat roof. Every year the snow and ice would pile up on it, and they'd have to send a crew out to clear it all off because it was so heavy and putting stress on the structure. They finally got smart and replaced those structures with one that has a pitched roof so all the snow and ice slides off now. The sun is finally out here today, and it's supposed to go up to 43 here.
They are generally fairly good about removing the snow. How fast they clear it is a function of how much snow fell and where we stand in the pecking order. The last snowfall we received it took about 8 hours until the parking lots were cleared. That was after a ~6 inch snowfall. It can take the shovel crew much longer when extreme cold temperatures hit after a snowstorm. This time of year, the apartment managers leave a shovel and a bucket of deicer for people that need to dig themselves out.
