This page was updated on Feb. 23, 2021, to show the latest figures on deferred maintenance at National Park Service sites in Arizona.
The National Park Service (NPS) is over 100 years old, and the infrastructure and facilities at the more than 400 sites it manages nationwide are aging. Add wear and tear from visitors and inconsistent annual funding, and the park service can’t keep pace with needed repairs. NPS’ maintenance backlog has grown to an estimated $13.1 billion, and more than half of that is for highest-priority assets.
