Spring Valley is close-built and greener than people expect — big street maples over narrow lots, backyards that end at a hedge, lawns measured in strides rather than acres. AMALIO J R TREE & LAWN SERVICES works at that scale: mowing the small yards, trimming the branches that hang low over a driveway or a walk, edging where turf meets sidewalk, and clearing the heavy leaf drop those maples let go every November. On a village lot every square foot shows, so the trimming counts for as much as the mowing. Get in, do it cleanly, sweep the sidewalk on the way out. By evening the block looks a little sharper than it did that morning.
