Tustin is a city located in Orange County, California, in the Los Angeles metropolitan area. As of 2018, Tustin had a population of 82,344.
The city is located next to the county seat, Santa Ana, and does not include North Tustin.
Because of a top 10% ranking in start-ups and sole proprietors per capita and one of the shortest commutes in Southern California, the city was chosen in 2009 by Forbes as one of the top 25 towns to live well in America.
Tustin was established as a real estate venture by a Petaluma carriage maker, Columbus Tustin. He and his partner, Nelson O. Stafford, purchased 1300 acres of the Rancho Santiago de Santa Ana in 1868 when the old Spanish land grant was being partitioned.
Between 1868 and 1872, Tustin set about establishing "Tustin City" on his share of the parcel. He laid the streets out through the wild mustard and sycamore trees that covered the area. He moved his wife, Mary, and their five children (Mary Jane, Martha, Ella, Fannie, and Samuel) here. He started selling lots and established the school district and the post office. When many people failed to buy homesites, he offered lots free to anyone who would build a home.
In 1877, Tustin competed unsuccessfully with William Spurgeon in Santa Ana for the southern terminus of the Southern-Pacific Railroad, thereby sealing the fate of his "city" -- Tustin would remain a small town, Santa Ana would become a city. Columbus Tustin died in 1883 a bitterly disappointed man.
Then, during the land boom of the 1880's, Tustin's prospects brightened.
