Section 71
SEC. 71. Payment of special assessment.-All sums due from any landowner or owners as the result of any action taken pursuant to this Act shall be payable to the city treasurer in the same manner as the annual ordinary tax levied upon real property, and shall be subject to the same penalties for delinquency and be enforced by the same means as said annual ordinary tax; and all said sums together with any of said penalties shall, from the dates on which they are assessed, constitute special liens on said land, with the sole exception of the lien for the non-payment of the ordinary real property tax. If, upon recomputation of the amount of special assessment in accordance with the next preceding section it appears that the landowner has paid more than what is correctly due from him the amount paid in excess shall be refunded to him immediately upon demand; in the other case, the landowner shall have one year within which to pay without penalty the amount still due from him. Said period shall be counted from the date the landowner received the proper notice.
