Persons claiming errors in the calculation of assessments shall bring the alleged errors to the attention of the City recorder. The City recorder shall determine whether there has been an error in fact. If the City recorder finds that there has been an error in fact, the City recorder shall recommend to the council an amendment to the assessment resolution to correct the error. Upon adoption of the correcting resolution, the City recorder shall cause the correction to be made in the City lien record and shall cause a corrected notice of assessment to be sent by first class mail to the owners of all affected properties.
