October in the Wheat Ridge Greenbelt turns the cottonwoods along the trail a hard yellow, and for a few weeks the town is doing two jobs at once — last mows and first shovels. TOPZ LAWN & SNOW, LLC is built for exactly that overlap: mowing, edging and cleanup while the grass still asks for it, plowing and walkway clearing the moment it stops. The changeover here is abrupt, and a warm Saturday followed by a Sunday under four inches is an ordinary weekend on this side of the metro. Whichever season is doing the talking, the aim holds — a yard that looks cared for, a drive that opens on the first pass. Wheat Ridge is the center of the map, with Arvada, Lakewood, Edgewater and Golden around it.
