"SECTION 6.3.  CITY CLEANING OR REPAIR; COSTS BECOME LIEN.
   The Council may, by ordinance, establish a procedure whereby City forces may clean any sidewalk, remove therefrom any debris or trash, or cut and remove limbs, branches, and parts of trees or shrubbery extending upon or overhanging any sidewalk after failure of the abutting property owner after 10 days' notice to do so. In such event, the cost of the repair, cleaning, cutting, or removal shall become a lien upon the abutting property equal to the lien for ad valorem taxes and may thereafter be collected either by suit in the name of the City or by foreclosure of the lien in the same manner and subject to the same rules, regulations, costs, and penalties as provided by law for the foreclosure of the lien on real estate for ad valorem taxes.
