No, if it was still in the budget Houston would still be in the dire situation it currently is, because A) as you mentioned, it was a 1000 year flood with enormous amounts of rain and, B) no one has cared enough to look at the big picture beyond, can we profit to,
should we profit. Houston is the worst area of the country for flooding, and they have no zoning laws. So for years, it's continued to sprawl out, putting concrete over natural wetlands. Wetlands that wouldn't have been able to stop all the rain they got from Harvey, but it would've helped to divert it better than sprawling concrete did. Nobody likes unnecessary government regulation, but sometimes it's necessary because it's good for the long term of our country, and it doesn't need to be stripped away just to undo what the last guy did. Besides, with the rebuilding that will be needed there, some of the regulations should be there to try and prevent future flooding, rather than doing it the same way we've always done.
