The first real flurry usually finds Paterson in early December, coming up the valley on a gray wind that makes the hills above Union Avenue look like a photograph. Fernando Landscaping LLC meets it with plows and shovels and salt, opening driveways and walks while the storm is still going instead of waiting for it to finish. The other half of the year the same trucks carry mowers, and the route runs on grass — cutting, trimming, edging, clearing beds, hauling leaves. Bunker Hill blocks are steep and close, so both jobs come down to careful passes in tight quarters. Green and clean in summer, open and safe in winter: two versions of the same promise to a street.
