One way to deal with flooding is to build highways in a manner where they become channels in such events. Kuala Lumpur, for example, has their SMART tunnel[1] which acts as a roadway normally but can be turned into a stormwater drainage tunnels.
Houston had a prime opportunity in 1996 to do something similar[2] when I-10 W was rebuilt- and engineers recommended building a conduit under I-10 to carry flood water from the Barker and Addicks reservoirs to the ship channel. Alas, that proposal was ignored so West Houston flooded during Harvey.

- sliverstorm 9y agoMis-step after mis-step. Is anything now being done differently in TX? Or is the plan to forget about it as soon as possible and cling to NFIP for next time?
- utexaspunk 9y agoI live in Houston and there may be something in the works but if so I haven't heard about it yet. I sure hope someone is working on it...

- utexaspunk 9y agoOne tunnel isn't going to solve all flooding problems in a huge city like KL. It's a step in the right direction, though.
- chimeracoder 9y agoIt's more complicated than that. > One way to deal with flooding is to build highways in a manner where they become channels in such events That's exactly what Houston did. The problem with this is that it makes evacuations more difficult and risky - the main ways for people to leave the city during a hurricane or flood become the canals for draining the water!
- utexaspunk 9y agoHouston didn't. I live here. Our freeways fill up with water but don't channel it away.
