This series contains (1) A-95 review documents, (2) A-85 review documents, (3) environmental impact statements, (4) project design plans and specifications, (5) resource assessments performed for structural sites to determine eligibility for nomination to the National Register of Historic Sites, (6) memorandums of agreement executed by the State Historic Preservation Officer, the Advisory Council and the project sponsor to comply with Section 106 of the National Historic Preservation Act of 1966 and (7) photographic inventories of structural properties with environmental impact project potential. These records were assembled in order to permit the evaluation of all Federally funded, licensed or sponsored projects which might adversely affect any cultural resource previously assigned National Register status. Furthermore, no construction project of any type may endanger a cultural resource, including even a suspected site for valuable archaeological investigation. It cannot be assumed, however, that all the types of records listed above are generated by the review of every State and Federal construction project. The bulk of the records are only present for projects actually involving some type of historic preservation such as the restoration of a historic structure.
