This series contains: individual files on each applicant for a historic preservation grant, including federal reports on financial status, expenditures, staff requirements, hiring practices and relocation assistance, if applicable, plans and specifications, historical research on sites, correspondence, payments requests, construction and non-construction forms, and grant award letters; federal audit reports; Department of Interior guidelines and criteria for the administration of the historic preservation program; annual Department of Natural Resources Board grant approval packages and updates; apportionment warrants (money requested); and photographs inscribed by staff for administrative purposes. The files are valuable primarily because of the Federal government requirement to report on the status of a restoration project every three years for a minimum of twenty years. These reports contain a great deal of historical and architectural research documentation which cannot be found elsewhere. As the date span indicates, these files pre-date the establishment of the Department of Natural Resources in the government reorganization of 1972.
