From the higher streets above Progress Ridge the land falls away south toward the Chehalem Mountains, and on a clear evening the whole Tualatin Valley turns the color of weak tea. Elite landscaping LLC works those hillside lots where the mowing lines have to follow the grade and every terrace edge has to be cut by hand. Mowing, edging, trimming and haul-away are what the day is made of, finished with a pass of the blower so the sloped drives are bare concrete again. Sidehill yards punish sloppiness — a wandering line shows from three houses down — so the discipline is in keeping every pass parallel and every border true. Handing back a hill lawn that reads clean from the street is the good part of the job.
