Research notes
Maryland contains two NPS-administered Civil War battlefields with federal-buffer implications and is adjacent to a third (Harpers Ferry, primarily in WV). Antietam (Washington County, Sharpsburg vicinity, 3,229 acres authorized boundary) is the most-visited Civil War site in Maryland; Washington County's zoning includes Battlefield Protection Districts and a 2003 MOA with NPS. Monocacy National Battlefield (Frederick County, 1,647 acres) has a similar protection framework. The federal preemption operates through §106 NHPA consultation on federal undertakings rather than direct zoning override; local jurisdictions retain primary zoning authority but routinely coordinate viewshed protection through MALPF, Rural Legacy, and the federal American Battlefield Protection Program (ABPP) easement-grant program. Listed under authority='federal' because the protection regime is federally-anchored rather than state-administered.
