Vacaville is a city located in Solano County in California, United States. Sitting about 35 miles (56 km) from Sacramento and 55 miles (89 km) from San Francisco, it is within the Sacramento Valley in Northern California. As of the 2020 census, Vacaville had a population of 102,386, making it the third-largest city in Solano County.[9]

Vacaville is named after Juan Manuel Vaca, who along with Juan Felipe Peña, owned Rancho Los Putos, which included the region from Vacaville to Davis.

Prior to European contact, the indigenous Patwin tribe lived in the area with the Ululato tribelet establishing a chiefdom around the Ululato village in what is now downtown Vacaville along the Ulatis Creek.[10]

The early settler pioneers of the land were Juan Manuel Cabeza Vaca and Juan Felipe Peña, who were awarded a 44,000-acre (18,000 ha) Mexican land grant in 1842.[11][12] The same year, Vaca and Peña's families settled in the area of Lagoon Valley.[12] Peña's Adobe home is the oldest standing building, built in 1842.[12]

Discussions for the sale of a portion of land to William McDaniel began in August 1850.[13] A written agreement was signed on December 13, 1851, forming a township, nine square miles of land were deeded to William McDaniel for $3,000, and the original city plans were laid out from that.[11][13] In the agreement, McDaniel's would name the new town after Juan Manuel Cabeza Vaca.[12]

Juan Felipe Peña (left) built the Peña Adobe (right) in 1842, making it the oldest building in Vacaville.

In 1880, Leonard Buck created the California Fruit Shipping Association, and the L.W. and F.H. Buck Company, an early company auctioning fruit in the state,[12][14] and Vacaville was soon home to many large produce companies and local farms, which flourished due to the Vaca Valley's rich soil.

It officially became a city in 1892.[12]

In 1885, the first grade school built was Ulatis School. In 1898, the town's first high school was built, Vacaville Union High School.[12]

In 1968, the Vacaville Heritage Council was established.

In August 2020, parts of Vacaville were evacuated due to the Hennessey Fire, which resulted in the burning of over 315,000 acres (127,476 ha) in five counties, including in Vacaville, where farms and homes were destroyed.[15]

On August 29, 2022, a truck transporting tomatoes crashed on Interstate 80 in Vacaville, injuring four, splattering over 150,000 of the tomatoes onto the eastbound section of the freeway, and significantly delaying eastbound traffic for hours. The peculiarity of the freeway accident subsequently resulted in international news coverage. [16]


A number of rare and endangered species occur in the Vacaville area. Endangered plants, which have historically occurred in the vernal pool areas in and around Vacaville include Legenre limosa, Plagiobothrys hystriculus, Downingia humilis, Contra Costa goldfields (Lasthenia conjugens), and showy Indian clover (Trifolium amoenum).[17] To this day Trifolium amoenum can still be found in Lagoon Valley Regional Park.

According to the United States Census Bureau, the city has a total area of 28.6 square miles (74 km2), of which 0.74% is covered by water. Excluding the Putah South Canal and minor local creeks, the only significant body of water within the city is the 105-acre (0.42 km2) Lagoon Valley Lake.

The unincorporated communities of Allendale and Elmira are generally considered to be part of "greater" Vacaville.
