National Park Service: Efforts to Identify and Manage the Maintenance Backlog

Pursuant to a congressional request, GAO reviewed the National Park Service's (NPS) efforts to identify and manage the maintenance backlog, focusing on: (1) NPS' estimate of the maintenance backlog and its composition; (2) how NPS determined the maintenance backlog estimate and whether it is reliable; (3) how NPS manages the backlog; and (4) what, if any, recent requirements or initiatives are being implemented by the NPS to help address its maintenance backlog problem.
