Joliet climbs away from the river in two steps, and the yards up on the bluff come with slopes, stone stairs and retaining walls a mower has to respect. GreenPeak Landscaping LLC handles that terrain — cutting across the grade, trimming the wall lines, edging where a walk falls away, mulch and bed work along the terraces. In winter the same pitch turns treacherous, so plowing and hand clearing come with salt on every step and landing. Hill yards take longer and look better for the trouble, the grade holding a crisp line all the way down. From up there you can watch the river while you work.
