In 2011, Jefferson County was $4.2 billion in debt and declared bankruptcy. The financial problems were related to costs of a huge sewer project. Corruption was found among six county commissioners. This was the largest Chapter 9 (municipal) bankruptcy in the United States, until it was surpassed by that of Detroit, Michigan in 2013. Jefferson County emerged from bankruptcy in December 2013, following the approval of a bankruptcy plan by the United States bankruptcy court for the Northern District of Alabama, writing off more than $1.4 billion of the debt.
