Flooding absolutely sucks, from first hand experience, my city is surrounded by hills and downtown is in a valley at the bottom, where I happened to live
due to brilliant city planning, the newer developed areas on said hills have 10 inch storm drains, which all run down to the city's core, which has older 5 inch drains, after a freak storm we got flooded pretty bad
fortunately it happened both in the summer, and receded after 12 hours or so, water was at around 4 feet, ended up with $70,000 in damages, and that was minimal compared to Jersey right now, going to be one hell of an ugly clean up
