In all cases where awards for damages have been made in condemnation proceedings, if the council believes that a portion of the city in the vicinity of the improvement will be benefitted by such improvement, they may, by an entry in their minutes, determine that the whole or any just proportion of the compensation awarded by the jury shall be assessed upon the owners or occupants of real estate deemed to be thus benefitted, and thereupon they shall, by resolution, fix and determine the district or portion of the city benefitted, and specify the amount to be assessed upon the owners or occupants of the taxable real estate therein. The amount of the benefit thus ascertained shall be assessed upon the owners or occupants of such taxable real estate in proportion, as nearly as may be, to the advantage which each such lot, parcel, or subdivision is deemed to acquire by the improvement. The assessment shall be made and the amount levied and collected in the same manner and by the same officers and proceedings, as near as may be provided in and by this charter for assessing, levying, and collecting the expense of a public improvement. The assessment roll containing said assessment, when ratified and confirmed by the council, shall be final, conclusive, and prima facie evidence of the regularity and legality of all proceedings prior thereto, and the assessment therein contained shall be and continue a lien on the premises on which the same is made until payment thereof. Whatever amount or portion of such awarded compensation shall not be raised in the manner herein provided shall be assessed, levied, and collected upon the taxable real estate of the City; as other general taxes are assessed and collected therein. At any sale which takes place of the assessed premises, or any portion thereof, delinquent for non-payment of the amount assessed and levied thereon, the City may become a purchaser.
