The property, including a ranch house, is located at 3500 Curry Canyon Road in Clayton and was sold by the Bertagnolli Family Estate to the Save Mount Diablo organization. It is believed to be one of the largest land purchases by the land conservation group.

Save Mount Diablo’s mission is to preserve Mount Diablo’s peaks, surrounding foothills and watersheds through land acquisition and preservation strategies designed to protect the mountain’s natural beauty, biological diversity and historic and agricultural heritage.

Additionally, the group seeks to enhance the area’s quality of life and provide recreational opportunities consistent with protection of natural resources. Since Save Mount Diablo’s founding in 1971, preserved open space has increased from less than 7,000 acres to some 110,000 acres in more than 40 parks.

“I’m proud to have played a role in helping preserve this beautiful wilderness area for visitors to enjoy today as well as for future generations to experience for many years to come,” Pierce said.

It is expected that parcel will eventually become a state or regional park with the ranch house serving as the residence for caretakers or the park ranger and perhaps serving as a staging area visitors preparing to hike the wilderness trails.

For Pierce, the acquisition was the culmination of two years of work to finalize the sale. Although he specializes in upscale residential real estate, the Realtor® does have a long and successful background in land acquisitions.

During his career, Pierce has brokered the sale of more than 10,000 acres of agricultural property and land slated for development in the San Joaquin and Sacramento valleys, as well as more than 1,000 acres of land for the Orinda Gateway development.

Before becoming a real estate agent, he worked in corporate real estate and industrial development for Crown-Zellerbach, the large paper manufacturer with more than four million acres of timberland.
