Blood, Trauma, and Biohazard Cleanup in Bostonia, CA

Bostonia is both a neighborhood of northeastern El Cajon and an adjacent unincorporated community in San Diego County; the portion outside the El Cajon city limits is classified as a census-designated place (CDP).

Although Bostonia is its own Census place, all mail sent to Bostonia is addressed to El Cajon.

In May 1953, residents of the southern portion of Bostonia voted to annex into the city of El Cajon by the close margin of 315 to 271, splitting the historic community between city and county.

The Bostonia CDP packs 16,882 residents (2020 census, up from 15,379 in 2010) into just 1.9 square miles of unincorporated land, most of it north of Broadway and east of State Route 67.

Bostonia has about 5,783 households (2020-2024 Census figures), averaging 2.88 people per household.

The land under Bostonia was part of the roughly 48,800-acre Rancho El Cajon grant made in 1845 to Dona Maria Antonio Estudillo, which also covered present-day El Cajon, Santee, Lakeside, and Flinn Springs.

The historic Bostonia Store, established in 1886 at the corner of 2nd Street and Broadway, served the community for nearly 74 years before closing in February 1960.

Local growers organized the Bostonia Fruit Growers and Packers Association on October 6, 1917, during the area's fruit-farming era; a former Virginia agriculturalist had even experimented with a tobacco crop in Bostonia back in 1896.

In 1981, Bostonia residents organized to complain about the disruption caused by the historic El Cajon Swap Meet, reputedly the 'granddaddy of all the nation's swap meets.'

Bostonia lends its name to Bostonia Elementary School, one of the public schools serving the El Cajon valley.
