Mangini Ranch’s . . .
. . . 208 acres swirl with importance. It winds sinuously through history, biology and geography much like Galindo Creek, the green-lined, blue thread whose headwaters spring up there. The Mangini Ranch represents most of the gap between Lime Ridge Open Space and Mt. Diablo State Park.

The property survived . . .
. . . Spaniards, Mexicans, American homesteaders, miners, railroads and suburbs. Many developers showed interest in the Mangini Ranch, but in 1990 the citizens of Contra Costa County voted to create an Urban Limit Line. The Mangini Ranch wound up outside of the line. Still, over the next thirteen years, one developer or realtor after another floated plans for Mangini. Instead, the Mangini family began negotiations with Save Mount Diablo and now their property has been preserved for all time (the property, however, is open only by guided tour until it passes to a public agency).

Save Mount Diablo would like to thank the Mangini Family,
California Coastal Conservancy, East Bay Regional Park District, the City of Concord, Walnut Creek Open Space Foundation, the Contra Costa Times’ Gary Bogue and his readers, and Save Mount Diablo’s members for their support in completing the acquisition. Please join us to dedicate this beautiful addition to preserved natural lands in Contra Costa County.
