National Park Service, Process Exists for Prioritizing Asset Maintenance Decisions, But Evaluation Could Improve Efforts

" The Park Service manages more than 75,000 assets, including buildings, roads, and water systems, at 413 park units across all 50 states. In 2015, the agency estimated that its deferred maintenance on these assets was $11.9 billion. GAO was asked to review how the Park Service manages its maintenance needs. This report examines, among other things, (1) agency allocations to maintain assets in fiscal years 2006 through 2015, (2) the amount and composition of the agency's deferred maintenance in fiscal years 2009 through 2015, and (3) how the agency makes maintenance decisions. To conduct this work, GAO analyzed Park Service allocation data for fiscal years 2006 through 2015 and deferred maintenance data in fiscal years 2009 (first year data for all assets was available) through 2015 (most current data available); reviewed planning and guidance documents and compared the process for making asset management decisions to guidance developed by the National Academies, among others; and interviewed Park Service officials at headquarters, all seven regions, and 21 park units selected to include those with large and small amounts of deferred maintenance, among other things. This sample is not generalizable to all park units. "
