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 its infrastructure each year and calculate how much it would cost to address needed repairs. The deferred maintenance and repairs (DM&R) cost is based on FY25 Federal Real Property Profile Data.

At the end of fiscal year 2025, an estimated $24 billion in 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.

President Trump's Great American Outdoors Act National Parks and Public Lands Legacy Restoration Fund, supported by revenue from energy development, provided 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 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.

The Federal Lands Recreation Enhancement Act (FLREA) enables the National Park Service and other federal agencies to collect recreation fees and to retain fee revenues at the site collected to improve visitors’ experiences across the nation. Visit the FLREA Project Spending dashboard to learn more about recreation fee revenue spending in national parks.The Federal Lands Transportation Program (FLTP), administered in partnership with the Federal Highway Administration's Federal Lands Highway office, funds transportation facilities owned and maintained by National Park Service. This includes multimodal projects, long-range planning, and asset management systems that improve the condition of National Park Service transportation networks.

Fiscal Year 2025 Quarter 4 Deferred Maintenance and Repair (DM&R) by Region

An asset is real property that the National Park Service tracks and manages as a distinct, identifiable entity. These entities may be physical structures or groupings of structures; landscapes; or other tangible properties that have a specific service or function.

The National Park Service maintains a complex portfolio of more than 70,000 assets, including historic structures, roads, bridges, trails, campgrounds, and utility systems. The NPS has extensive preventive and recurring maintenance needs resulting from aging infrastructure and use which often exceeds the capacity for which it was designed. National Park Service staff at each park inspect assets to assess their condition. DM&R figures represent the funding necessary to bring National Park Service assets to an acceptable and safe condition.
