State, tribal, and local laws and policies
The federal National Historic Preservation Act has served as a guide for the development of many state, local, and tribal historic preservation laws and ordinances. The scope of non-federal laws and policies tend to mirror federal historic preservation and archeological resources laws and regulations (i.e., National Historical Preservation Act; Archaeological Resources Protection Act; Secretary of the Interior's Standards and Guidelines for Archeology and Historic Preservation). However, non-federal entities, especially in the last decade, tend to write more detail into their historic preservation and archeological resource protection laws and policies than appears in a corresponding federal law or policy.
