The California Department of Parks and Recreation, more commonly known as California State Parks, manages the California state parks system. The system administers 279 separate park units on 1.4 million acres (570,000 hectares), with over of coastline; of lake and river frontage; nearly 15,000 campsites; and of hiking, biking, and equestrian trails. Headquartered in Sacramento, park administration is divided into 21 districts. The California State Parks system is the largest state park system in the United States. History California's first state park was the Yosemite Grant, which today constitutes part of Yosemite National Park. In 1864, the federal government set aside Yosemite Valley for preservation and ceded the land to the state, which managed the famous glacial valley until 1906. California's oldest state park, Big Basin Redwoods State Park, was founded in 1902. Until 1921, each park was managed by an independent commission or agency. In 1927, the California Legislature, with the support of Governor C. C. Young, established the State Park Commission, and its original membership included: Major Frederick R. Burnham, W. F. Chandler, William E. Colby (Secretary), Henry W. O'Melveny, and Dr. Ray Lyman Wilbur. The following year, a newly established State Park Commission began gathering support for the first state park bond issue. Its efforts were rewarded in 1928 when Californians voted nearly three-to-one in favor of a $6 million park bond act. In addition, Frederick Law Olmsted Jr. completed a statewide survey of potential park lands that defined basic long-range goals and provided guidance for the acquisition and development of state parks. With Newton B. Drury (later to be named director of the National Park Service) serving as acquisition officer, the new system of state parks rapidly began to grow. William Penn Mott Jr. served as director of the agency under Governor Ronald Reagan. In May 2008 The National Trust for Historic Preservation listed the park system as a whole on their list of America's Most Endangered Places. Proposed closures On January 10, 2008, Governor Schwarzenegger's office announced that the California State Park System will consider indefinite closures of all or part of 48 specific individual parks (one in five) to help meet the challenges of the looming (projected) $14.5 billion deficit facing California for its 2008-2009 budget year. At least $1 million of more than $14 million in total proposed cuts resulting from park closures would take place during the current budget year. The deficit
