Pomona is located Los Angeles County in California (CA). Pomona is a city in Los Angeles County, California, on the western edge of the Pomona Valley branch of the Empire interior region since the entire city is located almost physically east of the San Jose Bridge Hills.
The city is named for Pomona, the ancient Roman goddess of fruit. In the typical Southern California way of the 1870s, boosters gave the city this name before a single orange tree had been planted within its boundaries. By the 1880s, however, the arrival of railroads and water from the Coachella Valley had made it the western anchor of the fruit-growing region that encompassed most of what is now unofficially known as the Inland Empire. Pomona was officially incorporated on January 1, 1888.
Pomona is not generally identified as part of the Inland Empire (sometimes designated “the 909,” although much of it has since received a new area code, “951”) because it is in Los Angeles County, compared to being in shore County, California or San Bernardino County, California counties). However, because Pomona is part of the 909 phone area code that includes many of the communities in the inner empire, and because of the San Jose hills on Pomona’s western city boundary that creates a “physical/psychological barrier” between Pomona and the rest of Los Angeles County, it would not be unusual to include Pomona within the definition of the inner empire. In 2005, the citizens of Pomona elected Norma Torres, the first woman of Guatemalan heritage to be elected to a mayoral post outside Guatemala.
