The City Treasurer shall record all sales of delinquent property in a book to be kept by him describing each parcel sold in the same order in which the delinquent property was advertised for sale, and including in separate columns the amount of the delinquent assessment, interest and all costs; how much and what part of each tract was sold, to whom sold, and the date of sale and the day of redemption. At the end of each year, the Treasurer shall endorse the book "City Treasurer's Special Tax Sale Record for the Year ," and shall file it in his office. Thereafter, whenever any portion of delinquent property which has been sold shall be redeemed, the City Treasurer shall enter in the record opposite the description of the delinquent property the fact that the delinquent property has been redeemed. At the expiration of the period for redemption, the City Treasurer shall file each yearly special tax sale record in the office of the City Recorder. (Ord. 90-05 § 8)
