Camelback Mountain turns copper about twenty minutes before sunset, and the yards along its flanks catch that color and hold onto it. Envision Luxury Builders keeps the grass on those hillside lots — mowing terraced strips, edging where turf meets stone and decomposed granite, trimming close around walls and steps, then clearing the trimmings out. Ground like this is never flat and never square; you take it in pieces and make the pieces agree with each other. When the last light slides off the red rock, a well-kept lawn reads like a green pool set below it. That is a fine thing to leave behind at the end of a Phoenix day.
