Water Hill is all short streets and steep little front yards, the kind of ground where a mower earns its keep on the way up. Arbor One Lawn Care LLC works those slopes in spring, when the soil is still soft underfoot and the grass comes on so fast you could nearly hear it happening. Weekly mowing, trimming around fence posts and stone walls, edging where turf meets sidewalk, and the long pull of spring and fall cleanups at either end. The satisfaction is all in the finish — the stripe, the clean edge, the porch swept behind you — and the neighborhood shows it off yard by yard. Ann Arbor lots are small, which only means every square foot of them is visible from the street.
