 Viera North Peak

Often, there is just one chance to protect a spectacular property.  The chance to preserve 165-acres once owned by the Viera family on the very slopes of Mount Diablo’s North Peak came in 2009 when Save Mount Diablo signed the purchase agreement.  Viera-North Peak has been one of Save Mount Diablo’s top five priorities for 25 years because of its location, spectacular views and unparalleled resources.

Save Mount Diablo’s late Founder Mary Bowerman’s wish to preserve the Viera ranching family’s property has been realized. The Viera – North Peak parcel is one of the highest in the East Bay with an elevation of 2,300 feet. The property is visible for over 200 miles and includes views of the Sierra, Half Dome and Mt. Whitney. Sharing a 2.5 mile border with Mount Diablo State Park and rising between the two peaks, Viera is the very heart of Mount Diablo.

contains diverse soil types supporting hundreds of plant species. Over 50 rare plants inhabit the area, some of which are globally rare such as the endemic Mount Diablo jewel flower and Mount Diablo fairy lantern. The acreage holds varied habitats necessary to sustain unique animal life as well, including the threatened Alameda whipsnake. From Mary Bowerman’s first studies of the unusual flora, the area has long been known to be incredibly rich in life and biologists have now confirmed this richness.

In 2009, Save Mount Diablo conducted its first capital campaign to raise the funds needed to finalize the acquisition purchase. SMD received a pledge from an anonymous donor for a challenge grant of $450,000 of which 90% was committed, largely by individual donors. With the assistance of Contra Costa Times columnist Gary Bogue and his generous friends, the remaining $100,000 was raised in 2010 to preserve Viera – North Peak forever.

Thank you to all the generous donors who helped to preserve Viera – North Peak
