Summer in Chico comes on hard: by mid-July the afternoons are pushing a hundred and the north wind can pull the moisture out of a lawn in a single day. That is when the leafy canopy over the Esplanade earns its keep, and when a sprinkler system that truly reaches every corner proves its worth. Chico Sprinkler Inc works on sprinkler systems and lawn care across the city, in a town threaded by the shady banks of Little Chico Creek. The work lives in small adjustments, a zone set to run before sunrise, a spray pattern nudged off the sidewalk, grass mowed and trimmed so it can use every drop. When the valley finally cools in late September, the lawns that come through greenest are the ones that never went thirsty.
