The Naugatuck runs loud through Seymour after a thaw, and the town's steep side streets carry that same downhill hurry all winter long. Alvarado Landscaping Services works both halves of the year here, plowing driveways and lots, shoveling walks and spreading salt and sand ahead of the morning commute, then mowing, trimming and edging once the valley greens up. A driveway cleared to bare pavement while it is still dark is its own small victory, and so is a lawn cut to a clean line in July. Cleanups in spring and fall carry a property between those two modes. Weather comes fast between the river and the ridges, and the craft is being ready before it arrives.
