In addition to Federal parks and private land owned by non-government organizations such as The Nature Conservancy, Virginia has a state park system. Many towns/cities/counties own and manage parks, along with regional organizations such as the Northern Virginia Regional Park Authority.
Carvins Cove Natural Reserve has been called the "second-largest municipal park in the nation."1 In that 12,672-acre watershed, the City of Roanoke owns the land above the 1,200-foot contour line, while the Western Virginia Water Authority controls the land below that contour line (including the reservoir).
Another large municipal park in Virginia is Newport News Park, at 8,000 acres.
