For the payment of any judgment obtained under the provisions of this subchapter against a local agency that is a self-insurer or not fully covered by liability insurance, the manner of paying a money judgment shall be based upon a proof of indebtedness or evidence of any estimated tax levy necessary for payment of the judgment and any other evidence or statements which the court of original jurisdiction may require. As an alternative to paying the money judgment in this manner, the court may provide for the judgment to be paid over a period of not less than one nor more than ten years. The interest rate on any judgment where payment is extended more than three years shall be at the rate prescribed by law for the first three years and at the rate of 6% for each remaining year.
