Claimed errors in the calculation of assessments shall be called to the attention of the recorder prior to any payment on account thereof. The recorder shall determine whether there is an error in fact. If he or she finds that there is an error in fact, he or she shall report the same to the council. The council may enact an amendment to the assessment ordinance to correct the error. Upon the enactment of such an amendment by the council, the recorder shall make the necessary correction in the docket of city liens and send by certified mail to the last known address of the owner a corrected notice of the assessment. (Prior code § 2.024)
