Irvine Co. gives 20,000 acres of open space to Orange County

The gift from Irvine Ranch developer Donald Bren, 78, completes the transfer of 50,000 acres into public hands for parks, greenways, and a recreational and wilderness preserve.

A rugged, 20,000-acre parcel of the original Irvine Ranch — a pristine landscape of steep canyons, native grassland and sycamore woodland that is home to golden eagles, mountain lions and dozens of rare and endangered species of plants and animals — became public property Tuesday in a historic deal with the developer who has sculpted the look of modern suburbia in Southern California.

The open-space land, a gift from Donald Bren and the Irvine Co., was unanimously accepted by the Orange County Board of Supervisors, which also approved a long-term plan to manage the natural habitat, designated a National Natural Landmark four years ago. In one swoop, the size of parkland owned by the county grew by more than half.

The transfer of a large part of the historic ranch was an important milestone, placing the last major chunk of open private land in public hands and signaling the end of an era of enormous growth for Orange County.

It also was the culmination of an effort that Bren, a 78-year-old multibillionaire, launched more than three decades ago when he took control of the 94,000-acre Irvine Ranch, about a fifth of Orange County.

"It's been a long trail, these last 30 years, and this is a very significant event for us," Bren said in a rare interview after the handover.

He called the private-public partnership on open spaces a rare example of "social entrepreneurship," adding that "I'm proud of the people in the company who spent so much time with these community partnerships. I couldn't be more pleased. This is an investment in the future. It lives forever, and that is in fact a legacy."

Over the years, Bren's vision as a developer has transformed the Orange County landscape. His Irvine Co. created a retail, commercial and suburban juggernaut on 44,000 acres of the ranch, from the Newport coast to the city of Irvine, becoming, in the process, one of the world's largest and most-copied developers of planned communities.

But he also set aside 50,000 acres for parks, greenways, and a recreational and wilderness preserve. More than half of that was previously donated to the public; the land given to the county Tuesday completes the transfer.

"I can't even begin to guess what the value of this property is. But in terms of its biological and geologic value, it is truly priceless," said Michael O'Connell, executive director of the Irvine Ranch Conservancy. "It's a world-class piece of land."

The conservancy, a nonprofit entity created by the Donald Bren Foundation, will continue to manage the land, under contract to the county's parks department.

The new county wilderness area extends from near the 91 Freeway south to the hills above Irvine, and parts of it are visible from both sides of the 241 toll road in eastern Orange County. It includes Loma Ridge, Laguna Laurel and Limestone Canyon, and plans are under way to create a new, 2,000-acre nature park, Black Star Canyon Regional Park, adjacent to the Cleveland National Forest.

Nearly five times the size of Griffith Park, the land is essentially one large tract, which makes it important ecologically. It is part of what scientists call a Mediterranean climate zone, an area characterized by dry, mild weather and coastal fog that covers just 2% of the planet but contains 20% of all known plant species.

The land is a "truly magnificent, a globally important 'hotspot' of biological diversity," said Albert Bennett, dean of the School of Biological Sciences at UC Irvine. He said students and faculty travel the world to study similarly endowed open spaces "and these local lands rival many of those places in their diversity and biological importance."

Scientists also regard the tract as a geological treasure, and parts of it preserve an intact record of the last 80 million years of Earth history.

The parkland is rare among similarly sized natural habitats in the United States because it is so close to a highly urbanized area — the land is within a half-hour drive of nearly 3 million people.

Much of the parkland is remote and untouched, though part of it has been accessible to the public in the past, mostly through naturalist-led hikes and recreation days when visitors can go mountain biking and horseback riding. But access to the sensitive habitat is limited, and the county says that is likely to continue as the county develops long-term preservation plans.

"We want to create as many opportunities as possible for people to connect to the land and care about it," O'Connell said. "But not so much that they love it too much and threaten the values that make it so special."

When the Irvine Co. announced the wilderness gift last year, some environmentalists raised questions about whether the county had the financial resources to protect it.
