Three arroyos give this place its name, and for most of the year they are nothing but sand and gravel — then an August cloudburst comes down off the mesa, they run brown for twenty minutes, and by supper they are dry again. Anytime Trash Services keeps yards through that season: lawns mowed on a steady turn, trimmer work along walls and walkways, weeds pulled from the beds, and every bit of the cuttings and yard debris loaded and gone. A clear lot is half the look of a good yard. Grass grows hard in the weeks after the rain and needs somebody keeping pace with it. Nothing left behind but a level cut and a swept drive.
