The retention ponds threaded through the Valley Lakes streets hold the morning sky flat, and a heron will stand in one for an entire mowing without moving. Valley Lakes Landscaping keeps those Avon lawns on a steady rotation: cut, trimmed around light posts and mailbox pads, edged back along the driveway aprons. Subdivision grass is unforgiving, sitting under every window and right beside a neighbor's for comparison. Getting the bands true across a long back yard is the craft, and the reward is a block that reads as one continuous green. On a still evening the whole place smells like water and cut grass.
