NPS Deferred Maintenance Reports

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 (DM) statistics for its portfolio of more than 75,000 constructed assets.

Due to the continuously changing nature of facilities data, only final, year-end data is reported in response to information requests from the Department of the Interior, the Office of Management and Budget, the media, Congress, 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:

What is deferred maintenance (DM)?
DM is maintenance that was not performed at the required intervals to ensure an acceptable facility condition to support the expected life cycle of an asset. It is the total of unfunded facilities deficiencies. These deficiencies require work to raise facilities and collateral equipment to a condition that meets accepted codes, laws and standards and to achieve service life expectancies.

Why do the DM numbers change each year?
For several years, NPS maintenance funding has not kept pace with its identified needs. In general, the maintenance needs are almost double the annual funding, which leads to an annual increase in DM. As maintenance work is identified through condition assessments and is not completed due to limited resources, DM increases. As identified maintenance work is funded and accomplished, DM decreases. Fundamentally, as long as NPS maintenance needs exceed annual funding levels, the DM total will continue to rise.

Will the DM numbers go up in FY 2016?
Most likely…yes. As long as NPS maintenance needs exceed annual funding levels, the DM total will continue to rise. However, Congress increased support in FY 2016 with an additional $90 million to address DM and an additional $28 million for transportation related DM, repairs, and construction. While these increases will enable the NPS to address more of its most critical requirements, the DM total will continue to grow.

How will the NPS be affected if DM continues to rise at its present rate?
As DM continues to rise, the NPS is forced to make tough, strategic decisions in order to protect its priority assets and ensure the effective functioning of mission critical assets. Assets are prioritized by interdisciplinary teams which measure an asset's contribution to protecting natural and cultural resources, visitor use, park operational support and asset substitutability.

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 deficiencies divided by the current replacement value for the asset. A lower FCI rating indicates better facility condition.

What is critical systems deferred maintenance?
Critical systems deferred maintenance refers to DM associated with 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.

How much deferred maintenance is attributed to the total NPS asset portfolio?
More than $11.927 billion in DM – work that has been postponed for more than a year and remains unresolved – can be attributed to the NPS asset portfolio. NPS managers care for over 400 uniquely American treasures consisting of more than 75,000 assets. Aging facilities, increasing use and insufficient funding all contribute to the growing backlog affecting these assets.

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 verifiable 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, mission criticality, historic significance, visitor satisfaction and available budgets. 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).
