NPS Deferred Maintenance Reports

Addressing deferred maintenance is a critical focus area of the National Park Service’s core mission to preserve parks and provide a world-class visitor experience. In addition to increased funding for construction and deferred maintenance projects, the FY 2019 budget includes a legislative proposal to establish a Public Lands Infrastructure Fund that would help address DM needs in the National Park System.

National Park Service deferred maintenance increased by $275 million (about 2.5 percent), reaching $11.6 billion at the end of fiscal year 2017. Increases in DM can be attributed to maintenance needs that exceed the Service’s capacity to address the work, and to inflationary increases in materials and construction costs.

Current Status Billions of Dollars
Total DM (Sept. 30, 2017) $11.607
DM for Paved Roads and Structures ‡ $5.900
DM for All Other Facilities † $5.707
Highest Priority Non-Transportation Facilities

‡ "Paved Roads and Structures" includes bridges, tunnels, paved parking areas, and paved roadways.
† "All Other Facilities" in the table above includes: buildings, housing, campgrounds, trails, waste water systems, water systems, unpaved roads, unpaved parking areas, utility systems, dams, constructed waterways, marinas, aviation systems, railroads, ships, monuments, fortifications, towers, interpretive media, and amphitheaters. (In the reports linked below, the first eight of those subcategories are broken out separately, with "All Others" encompassing the remaining.)

Deferred Maintenance (DM) is maintenance and repairs of assets that was not performed when it should have been and is delayed for a future period.

At the end of each fiscal year, the National Park Service (NPS) Park Facility Management Division (PFMD) takes a snapshot of maintenance data and generates final annual deferred maintenance statistics for its portfolio of more than 75,000 constructed assets.

Information about those constructed assets is entered into a database and managed at the unit level almost every day of the week. The bureau aggregates unit information to prepare the reports presented above. Due to the continuously changing nature of facilities data, only final, year-end aggregates are reported, which ensures consistent reference. That snapshot of year-end data is quoted in response to information requests from the Department of the Interior, the Office of Management and Budget, Congress, the media, and other requestors. The NPS does not report "live" data and does not update reports on request. The statistics from the previous fiscal year are reported as consistent numbers throughout the current fiscal year.


Frequently Asked Questions:

Why do the DM numbers change each year?

As maintenance and repair work is identified through condition assessments and not completed on schedule, DM increases. DM decreases when work orders are closed out or when maintenance work is accomplished. As the NPS reviews, quality checks and improves its data — or when work and materials cost estimates change — DM statistics fluctuate up or down accordingly.

Can deferred maintenance be mitigated or even fully eliminated?
With adequate funding and proper investment, DM can be significantly reduced to a manageable level, but not fully eliminated.

What is the facility condition index?
The facility condition index (FCI) is a measure of a facility's relative condition at a particular point in time. The FCI rating is a ratio of the cost of repair of the asset's deferred maintenance divided by the current replacement value for the asset. A lower FCI rating indicates better facility condition.

What are critical systems?
A critical system is a system, sub-system, or piece of equipment that is essential to the effective functioning of an asset. Some examples of critical systems for buildings are roofs; foundation components; exterior doors; and heating, ventilation and air conditioning (HVAC) components.

What is critical systems deferred maintenance (CSDM)?
CSDM is associated with the proper upkeep of an asset’s critical system. While its name may indicate that all CSDM is of high importance to the bureau, the truth is more complex. The NPS prioritizes its maintenance work by the mission importance of the asset itself, and not by an asset’s critical systems. If the asset itself is not a priority, the CSDM connected to it is also not a priority.

How does the NPS define assets?
The NPS defines an asset as real property which the NPS tracks and manages as a distinct identifiable entity. These entities may be physical structures or groupings of structures; landscapes; or other tangible properties which have a specific service or function, such as a farm, cemetery, campground, marina or a sewage treatment plant.

How does the NPS identify deferred maintenance?
NPS staff at each park review and validate the asset inventory, conduct inspections to identify deficiencies, and document the condition as measured against the applicable maintenance or condition standards. This process is called condition assessment. Parks complete assessments on a recurring cycle. This provides the basis for long–range maintenance planning as well as annual work and budget planning. Further, assessments help parks develop deficiency cost estimates and determine the current condition of a facility.

How does the NPS prioritize work to maximize limited funding and address DM?
The NPS actively uses facilities and financial data to support both day-to-day work management and long-term strategic decisions. NPS resources are primarily directed to DM affecting the highest priority assets that support mission-critical infrastructure and visitor service. Target projects include critically needed repairs to existing assets, as well as demolition projects for assets that are no longer needed or that create a risk within parks. The NPS uses a standard, servicewide priority-setting approach to align investment decisions with a number of factors, including, financial sustainability, resource protection, visitor use, and health and safety. It is based on empirical data and uses the business systems in place to direct investments to the highest priorities.

How does the NPS store and maintain asset data?
Since 1986, the NPS has used computerized maintenance management systems to support workload inventories of real property; maintenance tasks that describe work performed on NPS assets; descriptions of work standards; work programs and performance budgets; work schedules and task prioritization; work orders that specify job authorizations and record work accomplished; and asset reports and analyses. The current NPS Facility Management Software System (FMSS) was deployed in 1998, and has been modified over time to meet NPS's unique needs for an asset management system. The FMSS is an asset-based work identification, work management and work analysis system. This "cradle to grave" system allows parks, regions and the NPS Washington Office to track asset conditions; asset operations and maintenance; repair and rehabilitation; and removal of assets.

How are deferred maintenance projects funded (e.g., individual park budget allocations, project funding sources, partnerships, agreements)?
DM is addressed by multiple funding sources including individual park budget allocations, project funding sources, concessions revenue, partnerships, agreements and grants, and the Federal Lands Recreation Enhancement Act (FLREA).

Why do the standard inventory reports here have different totals compared to similar NPS reports, such as those submitted to the Federal Accounting Standards Advisory Board (FASAB) or the Federal Real Property Profile (FRPP) information sent to the General Services Administration (GSA)?
The standard inventory reports posted above include the total of all assets that the NPS tracks for all reporting types. Government organizations, like the GSA or the FASAB, only require the NPS to report specific subsets of the total focused on their individual authorities or areas of responsibility. Because of the varying requirements, there are slight variations in the total inventory count, DM, and other data elements presented in different reports.
