Chino Hills saw its first use back in 1771 as land used for grazing cattle that belonged to the San Gabriel Mission until being sold to Richard Gird in 1848 after Mexico ceded it to the United States. The city began to see a population growth in the early 1920’s when both a mineral springs and a country club were both built in the city. The mineral springs were built in an area of the city known as sleep hollow otherwise known as carbon canyon. The springs became a getaway from the big city and soon saw small dwellings being built around it. In the 1960’s the springs became a constant hang out for hippies and many permanent houses were built during that time to accommodate those that would hang out there. Unfortunately today they springs are no longer open but many of the houses still remain. The Los Serranos country club was opened in 1925 which allowed members to buy small lots of land around the club on which many members would build cabanas or casitas for weekend getaways which led to future more permanent housing. The town remained relatively rural up until the 1970’s due to its topography of rolling hills which made it quiet expensive to develop so it was mostly used for dairies or equestrian use. In 1979, the County of San Bernardino initiated the development of the Chino Hills Specific Plan which laid out a plan for future development of over 18,000 acres. This plan was to become the first of its kind in California to be used on an unincorporated area due to the overwhelming pressures of people wanting to move there. By 1982 the plan was approved and extensive housing developments followed throughout the 1980s and early 1990s, only slowing down in recent years. The city was eventually incorporated on December 1st 1991 as has grown from a population of 42,000 before incorporation to over 78,000 today. The city is now considered a sub-urban community in the upper middle class with an average household income
