Definitely time for a variety of known mitigation measures to be enacted and enforced.
No flood control system is designed to handle upwards of 50″ of rain so this notion that if there was better planning that flooding would have been minimized is rather silly. However, to deny or refuse to acknowledge that development increases the impact of flooding is equally as silly.
