Fla. Stat. § 170.14

If any special assessment made under the provisions of this chapter to defray the whole or any part of the expense of any said improvement shall be either in whole or in part annulled, vacated or set aside by the judgment of any court, or if the governing authority of any municipality shall be satisfied that any such assessment is so irregular or defective that the same cannot be enforced or collected, or if the governing authority of a municipality shall have omitted to make such assessment when it might have done so, the governing authority of the municipality shall take all necessary steps to cause a new assessment to be made for the whole or any part of any improvement or against any property benefited by any improvement, following as nearly as may be the provisions of this chapter and in case such second assessment shall be annulled, said governing authority of any municipality may obtain and make other assessments until a valid assessment shall be made.
