Carlstadt sits on a rise above the Meadowlands, and on a clear morning the marsh below goes silver while the Manhattan skyline stands up sharp along the horizon. Between the warehouse blocks and Washington Avenue there are neat residential streets with lawns kept trim behind low hedges. Walter Dotto Lawn Services mows, edges and trims them on a steady rotation, keeping the strips beside walks and driveways clean and handling the cleanups at either end of the season. Wind off the meadows carries grit and damp, and the growing season here runs long and green — fine conditions for grass, demanding ones for tidiness. A row of Carlstadt lawns cut and edged on the same afternoon makes a fine sight against all that industry.
