The City of Houston, which votes Democrat, has actually done a reasonable job of upgrading its infrastructure over the years. For example all roads built/upgraded since the 90s are designed to act as drainage systems. The problem is that Houston is a big city and its population has been rising very quickly, and the city government's efforts have been insufficient. And since the Texas state government is dominated by gotta-keep-government-small-and-taxes-low Republicans, Houston has received almost no assistance from the state in this regard. We are seeing the results of that today.
