Before modern housing developments replaced pastureland, Chino supported dense agricultural and dairy operations across San Bernardino County. Decades of livestock use and irrigation changed upper soil layers, creating pockets of soft organic matter that settle unevenly. For a community where the average household has 3.83 people using outdoor areas daily, excavating down to firm mineral dirt prevents slabs from hollow settling.
The city now records a population of 89,797 residents across older agricultural parcels and master planned tracts like College Park. In newer neighborhoods, compact lot boundaries require specialized equipment to access side yards and backyards without damaging perimeter fencing or municipal sidewalks. Our crew uses tracked haulers that distribute weight evenly, preserving underground utility lines and adjacent yard grading throughout prep work.
With a population density of 1,169 people per square mile, residential street parking is common, requiring strict coordination for concrete transit mixers. Fast transit from the plant to the jobsite is essential because high summer temperatures in the Inland Empire cause concrete to hydrate quickly. We adjust mix retarders, moisten subgrade gravel before the pour, and start finishing early in the day to prevent rapid surface drying and shrinkage fractures.
