Bloomington is an urban unincorporated community in San Bernardino County, California, United States. The population was 23,851 at the 2010 census, up from 19,318 at the 2000 census. For statistical purposes, the United States Census Bureau has defined Bloomington as a census-designated place (CDP).

Though currently unincorporated, many of the town's political activists are pushing for Bloomington to attain cityhood, while the nearby cities of Rialto and Fontana are attempting to annex the community. The incorporation effort is led by the Bloomington Incorporation Committee.^[3]

Bloomington was originally developed as part of the land holdings of the Semi-Tropic Land and Water Company, which was formed in 1887.

In 1907, the Riverside Portland Cement Company built a large plant near the Crestmore Quarries (South Bloomington), and to provide transportation for employees built a standard gauge railroad to Riverside. On May 20, 1911 the line was opened to Bloomington. The original community, known as Crestmore, is generally located between Locust Avenue and Larch Avenue, south of Jurupa Avenue, extending to the Riverside County line. The Pacific Electric Crestmore Line (Riverside–Rialto) provided local service for many years.

The Semi-Tropic Land and Water Company (now known as West Valley Water District) laid out the town sites of Bloomington, Rialto, Fontana, and Sansevaine. The town site for Bloomington, after being surveyed in April, 1888, was bounded on the north by Valley Boulevard, on the south by Slover Avenue, on the east by Larch Avenue, and on the west by Linden Avenue.

Part of the community is still rural and many residents continue to keep and raise animals.^[4] The cities of Rialto and Colton are both trying to annex much of the land now within Bloomington.

In 1989, full incorporation was not completed due to budget and staff constraints.^[4]

In 2007, the Bloomington Incorporation Committee (BIC) applied with the Local Agency Formation Commission for another attempt for incorporation. It failed in late February and early March, when the Local Agency Formation Commission denied an extension that BIC needed in order to pay a $109,000 deposit for feasibility and financial studies.^[5]

In 2022, there was protest by community members, when the county approved to destroy an elementary school in favor of a warehouse^[6][7]

In 2024, community members protested the demolition of 117 homes in favor of warehouses that were approved by the county supervisors^[8][9][10]

In late September 2024, a San Bernardino County Superior Court Judge halted all construction on the Bloomington Business Park, finding that the San Bernardino County officials had failed to conform to state law in its Environmental Review by not sufficiently informing stake-holders (decision-makers and the public) of the environmental consequences of the proposed development. The County will have to re-do the Environmental Review so as to conform to State Law. Community members bemoaned the loss of over 100 homes in a project that may not proceed.[1]
