The green copper dome of the Bergen County courthouse sits over Hackensack like a landmark you steer by, brick and granite below it and the streets running out in every direction from there. Steelmack Landscaping Contractors takes on the grounds around that kind of building and the homes beyond it, where a property is judged first by its edges. Snow season here can turn overnight — a system swings in off the Meadowlands and by dawn the lots have to be plowed wide, corners pushed back, salt laid so the walkways stay bare all day. Once the thaw sets in, the same properties are mowed on a schedule, beds cut fresh and the shrubs kept in shape. A crisply finished lawn in front of an old brick front is a small civic pleasure, and it holds across Hackensack, River Edge, Oradell and Paramus.
