Home to Birmingham, Alabama’s largest city, Jefferson County sought to reorganize its finances in fall 2011 under Chapter 9 of the federal bankruptcy code. A failed overhaul of its sewer system and other bad decisions left the county reeling under more $4 billion of debt and unable to raise taxes, fees, or payments for bonds issued by Wall Street banks. An earlier decision by the state Supreme Court striking down a local income tax has forced county officials to try to persuade the state Legislature to authorize another tax or warn of new budget cutbacks.
