The Certified Local Government Program of the State of California resulted from 1988 amendments to the National Historic Preservation Act that encouraged local governments to identify, evaluate, register, and preserve historic properties. It also integrates preservation interests and concerns into local planning and decision-making processes. To become a Certified Local Government (CLG), a local government needs to complete an application, meet CLG criteria, and be certified by the National Parks Service. A certification agreement is then formalized between the National Parks Service, the State Office of Historic Preservation and the local government. This enables the federal and state programs to delegate various preservation responsibilities to the local level.
