Placentia and Yorba Linda anchor this landscape during a period of rapid suburban expansion in Orange County. The 1978-era urban growth, marked in purple, pushes into the Puente Hills and Chino Hills, contrasting with the extensive Oil Field operations and citrus heritage of the Ca&on De Santa Ana. While new residential tracts fill the valleys, older landmarks like the La Vida Mineral Springs and the Robert Diemer Filtration Plant remain central to the local geography.
