Ecorse Creek runs low and quiet through Allen Park, and in January the cold comes up off it and stiffens every driveway in the neighborhood. Allen Park Lawn & Snow LLC meets that early — plowing, shoveling porches and walks, spreading salt on the steps where ice likes to hide. Come April the same routes turn green and the work becomes mowing, edging and hauling out whatever winter left behind. Two seasons, one set of streets, learned block by block. The measure never changes: a cleared driveway before the first commute, a crisp edge before the weekend.
