A private border wall built along the Rio Grande in South Texas could collapse during extreme flooding, according to a federally commissioned inspection report that the government sought to keep secret for more than a year.
The 404-page report, produced by the global engineering firm Arcadis, confirms previous reporting from ProPublica and The Texas Tribune. It also shows for the first time that the federal government independently found structural problems with the border fencing before reaching a settlement agreement with the builder, Fisher Industries, in May.
