History

The area that eventually became Lemon Grove was part of Mission San Diego de Alcalá, one of the Spanish missions in California. After Mexico became independent from Spain, the Californios (residents of Alta California) ranched on various land grants. The area that now includes Lemon Grove was granted to Santiago Argüello, who received more than 59,000 acres.

The first proprietor of Lemon Grove, Robert Allison, arrived in the region in 1850, coming from Sacramento. He purchased thousands of acres from Santiago Argüello's heirs; this land eventually became Lemon Grove, La Mesa, Encanto, and part of Spring Valley. Allison became a director and stockholder of the San Diego and Cuyamaca Railroad in 1886 and built the Allison Flume. Allison's son Joseph filed subdivision maps for "Lemon Grove" in 1892. The name is attributed to Joseph's mother, Tempa Waterman Allison. The climate was suitable for the cultivation of subtropical fruits and vegetables, and farmers from the East and Midwest flocked to the region.

By World War II, most of the citrus groves had disappeared and suburbanization had begun. There had been four elections on incorporation from the 1950s to the 1970s; the issue caused heated debate in the town. The city was finally incorporated on July 1, 1977, becoming California's 414th city.<!-- Wikipedia needs short article on "General law (California)" --> however, it continues to receive law enforcement services, via contract, from the San Diego County Sheriff's Office.
