By the Numbers

To help us understand infrastructure funding needs and prioritize where we invest financial resources, the National Park Service assesses the condition of our infrastructure each year and calculate how much it would cost to address needed repairs.

At the end of fiscal year 2022, an estimated $22.3 billion of repair need existed on roads, buildings, utility systems, and other structures and facilities across the National Park System. Addressing deferred maintenance and repairs (DM&R) is critical to the continued preservation, accessibility, and enjoyment of national parks.

The Great American Outdoors Act’s National Parks and Public Lands Legacy Restoration Fund, supported by revenue from energy development, provides up to $1.3 billion per year for five years through 2025, to make significant enhancements in national parks. Understanding where the greatest deferred maintenance and repair needs are is part of a concerted effort to address the extensive repair backlog in national parks and ensure visitors can continue to enjoy their national parks for generations to come.

*All Others captures non-industry standard assets including utility systems, dams, constructed waterways, marinas, aviation systems, railroads, ships, monuments, fortifications, towers, interpretive media and amphitheaters. Note that the work order methodology is still being used to calculate DM&R for these assets as the National Park Service continues to improve the data quality for this subset of the portfolio.
