Historic Preservation Fund: The National Historic Preservation Act of 1966 (NHPA) envisioned a funding source to provide states with matching funds to implement the Act.  The Act was to be implemented through partnerships with states, Indian Tribes, Native Hawaiians, local governments, nonprofit organizations, and the private sector.  It brought forth state programs to implement much of the Act; a National Register of Historic Places encompassing a wide range of sites and structures deemed historic; partnerships at all levels of government; incentives; assistance; and reviews.  The NHPA endorsed the use of federal financial support for the national preservation program and called for two basic categories of assistance, both of which provide funding, rather than technical assistance, for historic preservation projects and to individuals for the preservation of properties listed in the National Register of Historic Places.  Since enactment in 1966, repeated efforts to fund the HPF was realized after a 10-year campaign when consistent funding was authorized on September 28, 1976, through Public Law 94-422.  The law amended the National Historic Preservation Act to establish a funding source known as the Historic Preservation Fund for a historic preservation grant program to provide assistance to non-federal entities.
