We come in from the east, along Limonite Avenue and up through Eastvale, which is 6.8 miles from the yard and the town we are in most weeks. That matters more than the mileage. Eastvale went up on the same preserve ground in the same years as the newest streets in south Chino, so the flatwork failing there at 18 years old is the flatwork about to go here, and a crew closing out an Eastvale job on the Thursday starts yours on the Friday.
The town is flat enough that the fall across a whole tract is measured in inches, so a drive sheds water over 60 feet with very little help and most of what reaches the clay under it arrives from a sprinkler rather than the sky. Irrigation on a timer holds one edge of a slab wet through the summer while the other edge bakes, and that difference across a single panel is what lifts a corner. Where the layout allows it we fall the slab away from the planted side.
Structural work is permitted by the Building Division at the City of Chino, and anything landing in the parkway or crossing the public walk takes a separate right-of-way file with Public Works. Both go in under our CSLB C-8 license, and the foreman who pours the slab is the one standing on it with the inspector. You hear from us when the counter comes back, rather than chasing it yourself.
