Santa Ana is the most populous city in Orange County, California and is the county seat. It lies approximately inland from the Pacific Ocean, on the largely seasonal Santa Ana River. The Santa Ana Freeway (Interstate 5) runs through the city, and the Costa Mesa Freeway (55 Freeway) and Garden Grove Freeway (22 Freeway) travel along its edges. It is today best-known for its enormous Hispanic population, now comprising about 80% of what was once a virtually all-white city. The current OMB metropolitan designation for Santa Ana and the Orange County Area is "Santa Ana-Anaheim-Irvine, CA." Despite its large Hispanic population and all-Hispanic city council, the city has never become a sanctuary city.
