9. Sidney, New York
A small and inconsequential place, it might not be immediately obvious why this is one of the worst places in America to live. The economy is reasonable, as are crime rates.
However, Sidney is located in one of the worst flood locations in the country. There are regular floods which cause millions worth of damage to residents properties – the most notable in recent times occurred in June 2006 when over 15 inches of rain fell in 3 days, causing $275mil worth of damage.
