North River Road follows the water east out of Mount Clemens, and by the third week of October the maples along it let go all at once, so a lawn can be buried between a Friday and a Monday. That is the busy, sweet-smelling stretch of the year for E & M Landscape and Design, LLC. — a last mow with the deck set low, beds trimmed back, leaves gathered and hauled until the grass shows again. Through the green months it is the steady rhythm instead: mowing, edging, string trimming, a yard kept level and tidy week over week. Then the blades go on the trucks and the same properties get plowed, shoveled and salted from the first squall to the last. Mount Clemens, Harrison Township and Clinton Township are all inside that circuit.
