In May the creek path through Cherry Creek is all new cottonwood shade, bicycles going by underneath, water moving along low and unhurried under the bridges. The blocks above it are brick and old street trees, the kind of neighborhood where a lawn is small enough that every flaw shows. Oak & Canyon Landscape mows, edges and trims those yards, working the tight strips along walks and the shaded patches where grass grows thin. A crisp edge against a brick sidewalk is the whole reward, and it is enough of one. Cleanups clear the leaf litter each fall so the beds and turf go into winter clean.
