San Antonio Homeless City
After receiving some complaints from nearby businesses near the highway the tunnels run beneath, officials in San Antonio, Texas, decided to tour the drainage tunnels in 2020 and found a large community of homeless people living beneath the city.
When local authorities looked into a report of someone entering a tunnel, they instead found a network of rooms and tunnels. The smaller tunnels gave way to a network of much larger tunnels that were over 10 feet tall, and within they found something the police chief called "unbelievable."
He described a little, underground settlement crammed with trash, furniture, food, and shopping carts. Apparently, the smell was revolting. The Covid-19 outbreak caused a rise in the community's population, although police have been conducting frequent searches to try to remove them.
