The Flint River loops through Genesee County and takes the big silver maples with it, and the township's neighborhoods sit under that canopy all summer. H&M Landscaping LLC mows those shaded lawns, working with the thin spots under the trees, edging the drives and walks, and trimming around mailboxes, fences and foundations. Clippings come off the pavement before they can blow into the street. When the season turns, the trucks go out with plows — drives opened wide, walks cleared, salt on the north side of a house where the sun never reaches. It is steady work on familiar streets, and the result is a block that looks looked-after.
