From the top of the bluff along Grandview Drive the lawns run right to the edge of the valley, and in September the light comes across the water low and long. Mark Hoerr Landscaping Inc mows and maintains ground like that — grass held to an even height across a slope, trimmed around beds and trees, edged where turf meets stone. Peoria's bluff yards are neither flat nor simple, and they ask for patience with the terrain more than anything else. There is something worth standing back for in a wide lawn cut clean, the mower lines running with the contour. The growing season is short here, so every good week gets used.
