It has always amazed me why so many new underpasses are being built below ground level. It seems like engineers would see they are building concrete river channels. Houston’s streets are terrible when we get a lot of rain at once. They put drainage systems in but I think the EPA is putting too little of a requirement on how much water they can move. They seem to only work right when we get a normal shower. If it is a real frog strangler the streets start flooding within minutes. It usually dissipates relatively quickly but with the rain we have been having there is just no place for it to go.
