September 7 in San Antonio history…
Rain began falling in San Antonio and would continue for three days leading to widespread flooding, killing 51 people and causing millions of dollars in damages. The flood was caused by some of the heaviest rainfall ever recorded in Texas. The immense amount of rain quickly overwhelmed the the San Antonio River. Most of the victims were trapped in their cars by the surprise flood and drowned. Five to 10 feet of water submerged the city’s streets, delaying an evacuation. The city was underwater for nearly a week following the flood, which was responsible for at least $5 million in damages. In the aftermath, San Antonio embarked on a 10-year overhaul of its flood system.
