The story of Irvine goes back more than 200 years, to a time when it was a vast, sprawling ranch extending from the brush-covered foothills of the Santa Ana Mountains to the dramatic bluffs of the Pacific coast. Since that time, the Irvine Ranch has experienced a revolutionary change from pastoral wide-open spaces to one of the most successful planned communities in the nation. All along the way, there were people whose vision shaped the transformation of Irvine. Among them were the members of the Irvine family, who for nearly a century were stewards of a ranch that amounted to more than one-fifth of modern-day Orange County. The Irvine of today owes its success to the ideals from its past: the determination to develop the immense potential of the land while still preserving its natural beauty.
