Where the full amount due the City is not paid by the owner within sixty days after the cutting, destroying or removal of such weeds, grass or deleterious or unhealthful growths or other noxious matter as set forth in this article, then the Chief of Police, acting as Health Officer, shall cause suit to be instituted on behalf of the city against such owner for the full cost, principal and interest, plus court costs if any. In the alternative, the Chief of Police may cause to be filed in the County Court a sworn statement of the cost and expense incurred for the work, the date, place and property on which the work was accomplished, and the recordation of such statement shall constitute a lien on the property, and shall remain in full force and effect for the amount due in principal and interest, plus costs of court, if any, for collection until final payment has been made. Such sworn statement shall be prima facie evidence that all formalities have been complied with, and that the work has been done properly and satisfactorily, and shall constitute full notice to the persons interested of the charge against the property. (1967 Code Sec. 15-21)
