Riverview Beach Park looks straight across the water at Wilmington, and the breeze off that channel is the first thing anyone notices on a Penns Grove morning. Oliver Landscapes, Inc works the town on both sides of the year — mowing, edging and trimming through the growing season, cleanups in spring and fall, then plowing, shoveling and salting once the weather hardens. Snow this close to the river is often more ice than powder, which puts the weight on salt and on arriving before it sets. Grass this close to the river is often more water than sun, which puts the weight on showing up on schedule. Different problems, one answer: be there, and leave it clean.
