Sunday evening near 16th Street Park is church bells and sprinklers and the smell of grass that was cut a few hours earlier. Soriano Landscaping Company puts that smell on the street — mowing, edging, trimming and cleaning up front and back yards across Bayonne, one block at a time. The yards here are compact, hemmed in by fences and driveways, which makes a neat finish more noticeable rather than less. Getting the border right along a walk takes a minute longer and pays for itself all week. The city sits on a narrow strip of land between two bays, and every square foot of green counts for something.
