California also has an environmental law (California Environmental Quality
Act [CEQA]) passed in 1970 that protects natural and cultural resources (or
at least requires identification and consideration of resources). Also, we
have a "California Register of Historic Places" that parallels the National
Register in intent and criteria.
Contact our California Office of Historic Preservation for more info. Their
