Assessment liens, priority, and fixing mistakes

(a) All assessments made pursuant to this chapter shall be a lien against each assessment unit assessed from the date of the first publication of the ordinance IMPROVEMENTS BY ASSESSMENTS § 12-32 declaring the assessment until paid and shall have priority over all other liens except the lien of property taxes and for other public purposes. The lien of assessments levied pursuant to this chapter shall be on a parity with the lien of property taxes and liens for other public purposes. As between liens of assessments made pursuant to this chapter, the earlier lien shall be superior to the later lien. (b) No delay, mistake, error, defect, or irregularity in any act or proceeding authorized by this chapter shall prejudice or invalidate any assessment. The delay, mistake, error, defect or irregularity may be remedied by subsequent or amended acts or proceedings and, when so remedied, the same shall take effect as of the date of the original act or proceeding. (c) If in any court of competent jurisdiction any assessment made under this chapter is set aside for irregularity in the proceedings, the council may, upon notice as required in making an original assessment, make a new assessment in accordance with the provisions of this chapter.
