Is Eastvale in a liquefaction zone, and does that change how my slab is built?
Yes, the city's building code ordinance says Eastvale as a whole is in a liquefaction zone, which is a statement about the city, not about your lot in particular. It also names the Chino-Central Avenue fault as the one that matters most here, with the Elsinore fault 9 miles away. For driveways and patios, that's one more reason we don't skimp on the base or the steel, and for foundations, the plans and the city's review set what's required.
