[7] San Jacinto will also be home to the eastern end of the Mid County Parkway, a planned route that would eventually connect it to the city of Perris.

The Luiseño were the original inhabitants of what later would be called the San Jacinto Valley, having many villages with residents.

[8][9] The Anza Trail, one of the first European overland routes to California, named after Juan Bautista de Anza,4 crossed the valley in the 1770s.

Mission padres named the valley, San Jacinto, which is Spanish for Saint Hyacinth, and around 1820 they established an outpost there.

[9] The local economy was built on agriculture for many years and the city also received a boost from the many tourists who visited the nearby hot springs.

The city, and its residents, helped to start the Ramona Pageant ( California's official State Outdoor Play), in 1923, and have supported the historic production ever since.

[11] On July 15, 1937, San Jacinto was the end point for the longest uninterrupted airplane flight to that date when Mikhail Gromov's crew of three made the historic 6,262-mile (10,078 km) polar flight from Moscow, USSR, in a Tupolev ANT-25.

In the early 1950s the fraternal group E Clampus Vitus and the Riverside County Department of Transportation commemorated the Gromov flight by erecting a stone marker on Cottonwood Avenue, just west of Sanderson Avenue in west-central San Jacinto.

Since local geological records have been kept, the city has been struck by two large earthquakes, one on Christmas Day in 1899, and the other on April 21, 1918.

San Jacinto has a hot-summer mediterranean climate (Köppen: Csa) hot, dry summers and cool, wet winters.

There were 14,977 housing units at an average density of 573.2 per square mile (221.3/km2), of which 8,943 (68.0%) were owner-occupied, and 4,209 (32.0%) were occupied by renters.

According to the 2010 United States Census, San Jacinto had a median household income of $47,453, with 18.9% of the population living below the federal poverty line.

Federal: State: Local: San Jacinto has a memorial to veterans at Druding Park is a tribute to the men and women of the U.S. Armed Services.

In the park, each branch of the military has an equipment artifact used by its members in battle, as a symbol of their services.

There is a tank for the Army, a propeller for the Air Force, an anchor for the Navy, a lighthouse for the Coast Guard, and in the near future the city government hopes to add a howitzer for the Marine Corps.

The two mansions and the grounds are all that remains of the original 35,000-acre (140 km2) Mexican land grant given to the brother's father, Jose Antonio Estudillo in 1842.
