Darien sits where the land finally gives itself over to Long Island Sound, and everything green here grows within reach of salt air. DORMES LANDSCAPING LLC keeps lawns and landscapes along the town's tidal edges — the low ground near the Goodwives River, the shaded lots off the Post Road, the yards that catch the last coppery light coming in off the water. A mower run made straight, a border cut clean against the grass: small things, but they are what a property is remembered by. The work is lawn care and landscape maintenance, kept at the pace the season asks for. By evening, when the marsh grass goes silver and the gulls turn inland, the lawns they have finished sit quiet and squared away.
