INGRAM, Texas — In the fall of 2021, a real estate executive whose company was planning to upgrade an RV park along the Guadalupe River assured officials that guests would have time to flee in the event of a flood.

People would stay “as close as we can get to the river,” Minh Tran, a partner at HTR Investors, the company that had recently bought the park, told Ingram’s City Council. “I love water,” he said. “A lot of RVers do.”
