Yucaipa has the distinction of being the longtime home to a large population of Serrano Native Americans.

The fertile valley was watered by springs and creeks running out of the San Bernardino Mountains.

The Serrano Americans lived in this location most of the year, but would make excursions into the mountains to gather acorns and other food items during their harvest season.

The Adobe's later owners included John Brown Sr., James W. Waters, and the Dunlap family; it was acquired by San Bernardino County in 1955.

[8] The nearby Oak Glen area is best known for its apple orchards, some of which are operated by the direct descendants of the original founders (the Parrish, Wilshire, Rivers, and Law families).

It had a maximum Mercalli intensity of VI (Strong) and was felt from downtown Los Angeles to some areas of San Diego.

[9] In 2016, Yucaipa broke ground on a multipurpose performing arts center on the corner of Acacia Avenue and California Street.

[10] Yucaipa is located in southern California, approximately 72 miles (116 km) east of Los Angeles.

The city is approximately 2,600 ft (790 m) above sea level and is bordered by Redlands to its west and Calimesa to its south.

The unincorporated communities of Cherry Valley, Mentone and Oak Glen collectively account for Yucaipa's northernmost outskirts.

According to the United States Census Bureau, the city has a total area of 27.8 square miles (72 km2), with 0.04 percent being water.

[18] From November 1999, Richard (Dick) D. Riddell was the longest-serving mayor (and the oldest, at age 88) in Yucaipa's history.

In November 2012, at the request of newly sworn councilman Bobby Duncan, Denise Hoyt was named the new Mayor.

Beaver was elected to Yucaipa's 4th district as the youngest councilman in the city's history at 32 years of age.

[19] The San Bernardino County Sheriff's Department serves Yucaipa—including the nearby unincorporated towns of Mentone, Oak Glen, Forest Falls, Angelus Oaks, and Mountain Home Village—from its regional station at 34282 Yucaipa Boulevard (a larger replacement opened on July 1, 2014, next to City Hall at 34144 Yucaipa Boulevard).
