The old blocks north of the river in Glenwood Springs are narrow-lotted and tree-lined, alleys behind and stone walks in front, and they ask for hand work as much as machine work. Rivas Lawn Care & Snow Removal, LLC keeps those yards through the green months — mowing, trimming, edging and hauling cuttings and leaves out of side yards too tight for anything wide. When the weather flips, those same walks get shoveled down to the stone and the drives get plowed and treated, because ice on a shaded sandstone step is nobody's friend. It is the kind of route where you learn every gate latch and every place the runoff crosses. Two services, one neighborhood, watched all the way around the calendar.
