When it appears to the Assembly that a special assessment is invalid or when an assessment is adjudged to be illegal by a court, the Assembly shall order a reassessment whether the improvement has been made or not. Proceedings for a reassessment and for the collection thereof shall be conducted in the same manner as if provided for the original assessment. (Ord. 80-16 § 3, 1980. 2004 Code § 3.05.080.)
