Rocklin takes its name from rock — the granite quarried out of these foothills — and the old quarry pits still show downtown, where Quarry Park now draws zip-liners and summer concert crowds. Guzman Concrete and Landscaping works in a town built on stone, where lawns sit beside drives and walks and the meeting of pavement and grass should run straight. Late spring in Placer County moves fast, with foothill grass going from green to straw under a few weeks of May sun, so a yard's lawn needs regular mowing and trimming to stay ahead of it. Guzman keeps turf cut, edges sharp against the concrete and the whole yard looking settled on its granite ground. It is work done with a stonecutter's respect for a true line.
