Existing Open Spaces

What we have achieved will be cherished for many years to come and forever preserved.

“My dream is that The Irvine Ranch will be known and celebrated as much for what will be here forever — the sweeping expanse of beautiful and valuable open space that will never be developed — as it is for the communities we have planned and built offering an unparalleled quality of life.” – Donald Bren

Donald Bren’s lifelong love of nature began as a young boy exploring the once-abundant open spaces in and around his native Los Angeles. “For me, open space is freedom,” he has often said when discussing why he has focused so much time, energy and financial resources on conservation. As a result of his vision and planning, more than half of The Irvine Ranch – an expanse exceeding 57,500 acres in the middle of urban Orange County – will be protected in perpetuity. It is a remarkable gift that will last forever.

Recent Gifts

In August 2014, Irvine Company Chairman Donald Bren announced that an additional 2,500 acres of pristine land on The Irvine Ranch was being permanently preserved as open space. The land, near the cities of Orange and Anaheim, had been fully entitled for as many as 5,500 new homes. But in a dramatic expansion of previous land gifts, Mr. Bren instead directed the land’s transfer to public ownership – a move that increased the permanently protected open space on the ranch to 57,500 acres, or 60% of the historic ranch. The gift created a vast interconnected network of canyons, and represented yet another tangible symbol of Mr. Bren’s abiding love of the land and his strong conservation leadership. And it created new opportunities for people to enjoy the beautiful natural resources on The Irvine Ranch … forever.

A community of diverse and dedicated stewardship partners has helped ensure that the wildlands and parks of The Irvine Ranch will be protected and accessible, forever.

Irvine Company has worked closely with conservation partners and other landowners to permanently preserve and protect America’s largest urban open space preserve, located within 30 minutes of three million people.  The landowners of the open spaces on The Irvine Ranch — Irvine Company, City of Irvine, County of Orange, and California State Parks — gratefully acknowledge the contributions of the many agencies, organizations and individuals who partner with us to keep the land beautiful, healthy and available for exploration.
