Glenn County, located in northern California’s agricultural region, maintained Road 37—a half-mile unpaved road that sees constant traffic from farm equipment, trucks, and local residents. The clay-based road struggled with washboarding, dust, and seasonal erosion due to heavy use and dry summer conditions. To address these challenges and reduce ongoing maintenance, Glenn County treated the road with Perma-Zyme. The application strengthened the native soil, reduced dust, and created a smoother, more reliable surface that has continued performing for over a decade under agricultural and residential traffic.
