Upon the happening of any emergency caused by the destruction or impairment of any municipal property necessary for the conduct of the affairs of the municipality, or by epidemic or threatened epidemic, or by the entry by a court of competent jurisdiction of a judgment for damages against the municipality, the governing body may meet any such emergency in the manner provided in this section. If there is a sufficient unexpended balance in any fund or funds except funds established for debt retirement to provide for the emergency, the governing body, by a resolution adopted by the vote of two-thirds of the members present at any meeting, or, if the governing body consists of less than three members, by a unanimous vote of all the members thereof, may take the amount necessary to meet the emergency from any such fund or funds. If the municipality has not reached its debt limit, the governing body, by the vote required to take moneys from a designated fund, may order its executive officer and financial committee to borrow an amount sufficient to meet the emergency. Any amount so borrowed must be for a time not to extend beyond the close of the fiscal year, and such amount and the interest thereon must be a part of the next budget. The resolution authorizing any emergency expenditure must recite the facts showing the existence of an emergency of the kind specified in this section.
