Historical Deferred Maintenance

The National Park Service maintains a complex portfolio of more than 75,000 assets (prior to 2024), including historic structures, roads, bridges, trails, campgrounds, and utility systems. We have extensive preventive and recurring maintenance needs resulting from aging infrastructure and heavy use which often exceeds the capacity for which it was designed. National Park Service staff at each park inspect assets to assess their condition. Deferred maintenance and repair (DM&R) figures represent the funding necessary to bring National Park Service assets to an acceptable and safe condition.

What's an asset?

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, such as a road, historic structure, campground, or sewage treatment plant.
