Historic Property Project Documentation

The National Park Service has a mission to protect and preserve the nation's heritage assets. The historic preservation work of the NPS is governed by federal law, federal regulations, and presidential executive orders.

At the same time, various factors can influence the projects that restore, rehabilitate, and preserve historic structures and cultural landscapes. There are multiple ways to document the research and decision-making that precede treatment.

About the Historic Property Project Documentation Tool

The Historic Property Project Documentation (HPPD) tool helps project teams to collect and integrate cultural resource management information into project planning and development. It provides a consistent format that can be used to inform and document federal decision making related to the treatment of historic structures and cultural landscapes. Currently, other cultural resource types are not captured in the HPPD.
