Detroit holds more open ground than people expect — the Rouge River winds through the west side under old hardwoods, and the parcels out that way run long and deep. Maple Valley Land Management takes on that kind of green: mowing wide turf, trimming the borders, knocking back brush and overgrowth, gathering leaves when October turns the maples above the river. Big properties ask for a plan rather than a quick pass, and a season of that planning shows up as a clean line where field meets lawn. By the first hard frost the ground is put away neat, nothing left to rot under the snow. Grounds care for the wide green parts of the city.
