Snow usually announces itself here late in the day — the light goes flat over the low ground and the old works along it, wind picks up off the hills, and by dinner the first flakes are holding on a cold road. Shego Construction & Landscaping LLC starts when that begins. Snow removal means plowing and pushing through the night, clearing drives and lots, opening walkways, then treating the ice that forms once a Morris County storm ends and the temperature keeps dropping. Grade decides nearly everything in Dover: a driveway that runs downhill to a garage needs a different plan than one that spills out toward the street. The work ends where it ought to — bare level pavement, edges squared off, no reason for anybody to give the storm another thought.
