Welcome to the Alameda-Tesla Property, your future new State Park Unit! Because the site isn’t open to the public, we invite you to explore the property’s rich natural, cultural, and historical resources virtually. We hope you will let your imagination soar, as you envision how you would like to experience the site in person when it becomes a part of the California State Park System.
The Alameda-Tesla Property includes more than 3,000 acres of creeks, floodplains, valley, hills and rock outcroppings in eastern Alameda County. Corral Hollow Creek flows east into the San Joaquin Valley, while Arroyo Seco creek flows west toward the city of Livermore. A narrow floodplain corridor characterized by riparian habitat parallels Corral Hollow Creek on the south side of Corral Hollow Road/Tesla Road. The surrounding hills support a mosaic of grasslands, scrub, and woodland habitats. A variety of plants and animals, some of which are species of concern with special protections, have been documented at Alameda-Tesla.
Tesla Road, a paved two-lane road, defines one edge of the property, and several unpaved roads provide access for adjacent private property owners and utilities servicing the electrical transmission lines that cross the property. State Parks’ Diablo Range District Office and maintenance yard, and several park staff residences are located on the northwestern portion of the property.
The Alameda-Tesla Property is a part of an ecologically-transitional area that straddles the Diablo Range and supports vegetation typical of both coast and inland communities. These vegetation types include Fremont cottonwood forest, blue oak woodland, valley oak woodland, California juniper woodland, ghost pine woodland, California sagebrush/black sage scrub, bush mallow scrub, mule fat thickets, patches of desert olive, choke cherry thickets, California native annual grasslands, and annual brome grassland. Creeks and stock ponds support wetland and aquatic communities at numerous locations throughout the site.
The property contains designated critical habitat for two endangered species, the Alameda whipsnake and the California red-legged frog. Species of concern found on the property include over a dozen plant species and more than twenty animal species (reptiles, amphibians, mammals, and birds). A diversity of more common species also inhabit the property, including those that quickly catch the eye, like bright green cottonwood trees and circling turkey vultures, and those that only appear occasionally, like spring wildflowers and shy black-tailed deer.
The Alameda-Tesla property is located in the Diablo Range, which is generally considered the approximate boundary between the Native American people of the Northern Valley Yokuts and the Ohlone. Evidence of Native American settlement has been documented in multiple locations in and near the Alameda-Tesla property.

In 1775, European explorers led by Juan Bautista de Anza passed through Corral Hollow Canyon, which includes the Alameda-Tesla property, on the historical expedition to Alta California. In the years that followed until 1998 when State Parks purchased the site, the property was used for an array of industrial and ranching activities.
