The Irvine Company traces its history to a ranch founded by
James Irvine I, Benjamin and Thomas Flint, and
Llewellyn Bixby in 1864 by combining three adjoining
Mexican land grants. A drought in 1864 killed the livestock of
Jose Antonio Sepulveda, forcing him to sell his coastal
Rancho San Joaquin to Irvine and his partners. In 1866 they purchased
Rancho Lomas de Santiago from
William Wolfskill; largely unfarmable due to its steep, hilly terrain, it had been used mainly as a
sheep ranch. In 1868 Flint, Bixby and Irvine were among the claimants of a title lawsuit that divided
Rancho Santiago de Santa Ana. Unlike other early Newport Beach landowners, Irvine and his partners had no interest in subdividing and selling, intent, instead, upon identifying the most lucrative agricultural uses for their enormous . The Irish-born Irvine met
Collis Huntington, soon to become one of the
Central Pacific Railroad (CPR) magnates, on a trip across the Atlantic. Rather than cementing a friendship, a disagreement that lasted throughout their lives resulted. When Huntington's
Southern Pacific Railroad (SP) needed Irvine's land for its route between Orange County and San Diego, Irvine refused. When SP crews began laying tracks on Irvine land without permission, ranch hands with shotguns confronted the crews. Eventually, Irvine gave the
Atchison, Topeka & Santa Fe Railway permission to build on his ranch. When Irvine died in 1886, trustees, left in control of the ranch until his son
James II (b.1867) turned 25, tried to sell it at auction. When this auction was declared illegal, James II took over the reins of the ranch and accelerated efforts to increase its agricultural production. In 1894, he incorporated the land holdings as the Irvine Company. Between the late 1800s to the 1970s, the Irvine Company continued to also run cattle operations on the property, with "
Bommer Canyon Cattle Camp" serving as its center. They also ran sheep. James Irvine remarked in 1867 that he and his men "rode about [the Irvine Ranch] a good deal, sometimes coming home in the evening after a thirty- or forty-mile ride pretty thoroughly tired out, but we had to do it in order to see much of the ranch and the flock." At the time, his Irvine Company had been purchasing further adjoining parcels of land, "[so] there [was] considerable riding to be done, if one [was] to see much of [the ranch]." In 1977, a group led by
A. Alfred Taubman and including real estate developer
Donald Bren bought the company from the Irvine Foundation. The Bommer Canyon area was sold to the City of Irvine between 1981 and 1982, ==Operations==
