Rialto, California is a city in the Inland Empire region of Southern California, located in San Bernardino County within the Los Angeles metropolitan area. Historically a transportation and agricultural center, Rialto lies along major corridors that connect Los Angeles, San Bernardino, California, Riverside, California, and the I-10 corridor. The city has evolved through phases tied to railroads, military installations, and suburban development.

History

Rialto's early history intersected with the expansion of the Atchison, Topeka and Santa Fe Railway, the regional influence of Spanish missions in California, and the land grants associated with Rancho Jurupa and Rancho Cucamonga. In the late 19th century, settlement patterns mirrored those of neighboring municipalities such as San Bernardino, California and Colton, California during the Southern Pacific and Santa Fe Railway realignments. The incorporation of the city in 1911 followed trends seen across Southern California during the Progressive Era and paralleled municipal formations like Pomona, California and Ontario, California.

During World War II, proximity to military sites including March Field and logistics routes tied Rialto to wartime mobilization, similar to communities near Riverside National Cemetery and Camp Anza. Postwar suburbanization reflected regional dynamics exemplified by Levittown-era housing booms, the development of Interstate 10 (California) and connections to employment centers in Downtown Los Angeles and Orange County, California. The late 20th century brought industrial growth linked to the Port of Los Angeles, warehousing expansions like those in Fontana, California, and demographic change comparable to San Gabriel Valley and Inland Empire trends.

Geography and climate

Rialto is situated in the western portion of San Bernardino County within the Inland Empire (California), bounded by Fontana, California, Colton, California, and unincorporated areas near Bloomington, California. The city occupies basin and foothill terrain at the western edge of the San Bernardino Mountains and within the hydrological sphere of the Santa Ana River. Major transportation arteries include Interstate 10, State Route 210 (California), and rail lines operated by BNSF Railway and Union Pacific Railroad.

The climate is Mediterranean to semi-arid, exhibiting hot, dry summers and mild winters similar to Los Angeles Basin microclimates and other Riverside County locales. Weather patterns are influenced by the Pacific High and occasional Santa Ana winds originating in the Great Basin.

The city's population includes communities with roots in Mexico, Central America, Asia, and domestic migration from counties such as Los Angeles County, California and Orange County, California.
