In any Class 7 municipality, in the case of any overgrown grass or weeds which may be abated pursuant to Article 4, commencing at Section 11-67-60, of this chapter, the city council may adopt procedures different from the procedures provided in Article 4 to declare overgrown grass or weeds to be a public nuisance and abated pursuant to the procedures provided in the ordinance. After the abatement of any overgrown grass or weeds pursuant to the procedures provided in the ordinance, the costs of abatement shall be assessed and collected as a weed lien in the same manner as provided in Section 11-67-66. The municipality may assess the costs authorized against any lot or lots or parcel or parcels of land purchased by the State of Alabama or any purchaser at any sale for the nonpayment of taxes, and where an assessment is made against a lot or lots or parcel or parcels of land, a subsequent redemption thereof by a person authorized to redeem or the sale thereof by the state shall not operate to discharge, or in any manner affect the lien of the municipality for the assessment. A person redeeming the property or purchaser at a sale by the state of any lot or lots or parcel or parcels of land upon which an assessment has been levied, whether prior to or subsequent to a sale to the state or purchaser for the nonpayment of taxes, shall take the same subject to the assessment.
