In Beach Haven West the lagoons run straight back from the bay, and the lawns stop at a bulkhead with the tide sliding by a foot below. CB Lawn and Landscape mows and trims those narrow, bright yards, where every cut is measured against a seawall and a dock line. At noon in July the water throws light up under the shrubs and the grass takes all of it in. The finish that matters is the edge — crisp along concrete, true along the bulkhead cap, nothing left floating. It is a small canvas, and that is exactly why it should look right.
