Watch: Aerial footage of stunning Santa Clara County ranch that sold for $63 million

On Thursday, the Peninsula Open Space Trust, a Palo Alto-based environmental group, announced it had purchased nearly all of the remaining land at Sargent Ranch, a vast property south of Gilroy along Highway 101 where Southern California investors sparked a 10-year controversy after proposing to build a sand-and-gravel quarry.

The purchase, from a group of San Diego investors called Sargent Ranch Partners LLC, was the third piece of property on the ranch that the land trust has bought since 2024.
