The National Park Service's (NPS) African American Civil Rights Grant Program (AACR) will document, interpret, and preserve the sites related to the African American struggle to gain equal rights as citizens in the 20th Century. The NPS 2008 report, "Civil Rights in America, A Framework for Identifying Significant Sites," will serve as the reference document in determining the appropriateness of proposed projects and properties. AACR Grants are funded by the Historic Preservation Fund (HPF), administered by the NPS, and will fund a broad range of preservation projects for historic sites including: architectural services, historic structure reports, preservation plans, and physical preservation to structures. Grants are awarded through a competitive process and do not require non-Federal match. There are separate funding announcements for physical preservation projects and for historical research/documentation projects. Funding announcement P18AS00485 is for physical preservation of historic sites only; P18AS00484 is for historical research/documentation projects only.
