For many across the country, the National Park system contains some of the most precious cultural and natural resources in the United States. At any given time, the National Park Service is working on dozens of long-term plans for the development and conservation of various properties under their oversight, including national monuments and national historic sites. This website provides access to current plans, environmental impact analyses, and related documents that are under review. Visitors to the site can search for plans by geographic region, by state, or by a drop-down menu of all of the various properties. The site also contains a number of other helpful links, including those that lead to a glossary of relevant terms and the Council on Environmental Policy.
