波多黎各面临飓风和地震恢复项目成本不断上升的问题。 Puerto Rico faces escalating costs for hurricane and earthquake recovery projects.

联邦审计发现，尽管有数百万美元的联邦资金可供使用，但波多黎各的大规模重建项目仍悬而未决。 A federal audit has found that large-scale rebuilding projects in Puerto Rico are still pending, despite millions of dollars of federal funding being available. 因此，在飓风“艾尔玛”和“玛丽亚”以及一系列地震之后，该群岛正在进行的恢复过程进展缓慢。 As a result, the islands ongoing recovery process after hurricanes Irma and Maria, and a series of earthquakes, is progressing slowly. 由于成本飙升和威胁全面重建的瓶颈，可用的 230 亿美元联邦资金中只有不到 10% 被支出。 Less than 10% of the available $23 billion federal funds have been spend due to the soaring costs and bottlenecks threatening full rebuilding. 报告强调，波多黎各的恢复工作自飓风“艾尔玛”和“玛丽亚”以来已经持续了六年多，还提到了2019年和2020年地震造成的破坏。 The report emphasized that Puerto Rico's recovery has been ongoing for more than six years since hurricanes Irma and Maria, and also mentioned the damage caused by earthquakes in 2019 and 2020.
