If hurricane Harvey dumped it's water on San Antonio instead

Alamo's basement would have flooded.

San Antonio here, first of all, we got ripped off, about half or less of the rain than we expected. The big rain stopped just short of us.

The main problem with Houston is that it is FLAT. It is at low elevation, along the coast, with a clay layer a few feet down to help ensure bad drainage. The only bad thing it doesn't have is sub-sea-level areas like New Orleans did. So the drainage is horrible. Areas that aren't flat get filled quickly.

It also has upstream stuff that got rained on. San Antonio doesn't really have any upstream to worry about because of the Hill Country to the north. Rain there drains into the underground aquifer that is the main freshwater source for SA.

Back in the '90s there was a storm that stalled over nearby New Braunfels for 24 hours (less than Allison and Harvey), and it was bad, but it was bad mostly along the Guadalupe River. Sure, San Antonio has low spots just like you can expect from any city, but it actually has some sort of drainage. It's also a lot farther from the coast, so a storm can't essentially pipe water in from the gulf like it can to coastal areas like Houston.

im from houston, the real reason houston happened is because they paved over wetlands and just kept expanding without building proper draining systems. And they are still expanding. This shit will just happen again, and it does every year with flash floods, this is just a flash flood that lasted a pretty long time. But if this shit happened before all the development, it could have handled it fine. It's just a giant concrete basin now

Of course if it happened before all the development, there wouldn't be development to get flooded.

San Antonio just has a lot less ways that it can be affected by flooding. Also, the San Antonio River downtown has a big underground bypass tunnel to handle the extra water from floods.
