Snow management turns into spring management so: if you can for you residents clearing your own snow and contractor's if you don't know this, when clearing north face side walks and driveways manage your snow as for from the side walk as you can onto the street, for south facing throw the snow onto the grass as for as possible. Reason's are: North facing it will not melt as fast in the sping and will develope mildow. South facing will melt quickly and the grass will be exposed to the sun quicker.
