WASHINGTON - The National Park Service (NPS) estimates that during Fiscal Year (FY) 2018, over $671 million in needed repair work was completed at national parks across the country, one of the largest amounts of deferred maintenance needs retired in a single year. This leaves, at the end of FY18, more than $11.9 billion in backlogged maintenance and repair needs for the more than 5,500 miles of paved roads, 17,000 miles of trails and 24,000 buildings that service visitors to America’s 418 national parks.

“Improvements to visitor facilities, campgrounds, trails, and backbone infrastructure are essential to providing a world-class experience to our more than 300 million annual visitors and a safe work environment for our employees, volunteers, and partners,” National Park Service Deputy Director Dan Smith said. “Addressing the deferred maintenance in our national parks is critical to our core mission and remains a top priority.”

The NPS saw 318.2 million recreation visits in 2018, the third highest total since record keeping began in 1904. The deferred maintenance figure increased by $313 million (2.7 percent) over FY 2017. Aging facilities, increased visitation, and resource constraints have kept the maintenance backlog between $11 billion and $12 billion since 2010.

Among the $671 million of backlogged maintenance projects the NPS successfully completed last year were a new roof over the visitor center at Gateway Arch National Park, a 26-mile pavement preservation project in Yosemite National Park, the restoration of native grasses at Nez Perce National Historical Park, and new paved trail surfaces at Independence National Historical Park.
