Lake Hiawatha lies flat along the Rockaway River, a grid of close streets and small yards in the corner of Parsippany-Troy Hills where the water is never far below the ground. Banta Landscaping Corp mows, trims, edges and cleans up those yards while the grass is running, then plows, shovels and salts once it stops. Driveways here are short and side by side, so a plow run is a matter of angles and courtesy — putting the snow where it belongs and not into the next house's apron. After a January storm the whole grid gets opened block by block, and by breakfast North Beverwyck Road is moving again. A neighborhood works because a lot of small jobs got done on time.
