On the northwest shore the ground rises into the grassy dunes of the Bayonne Golf Club, an unlikely stretch of links weather on the edge of Newark Bay. Platinum Construction & Landscaping brings that same attention to grass in yards all over the city — mowing, edging, trimming and seasonal cleanup, week in and week out. An August noon here manages to be bright and windy at the same time, and turf that gets cut on schedule takes it far better than turf that gets rescued. The line where a lawn meets the walk is worth doing slowly. Finished, a small Bayonne yard can look as intentional as anything with a view of the water.
