(a) No owner of any lot or land abutting upon any street shall refuse, fail or neglect to repair or keep in repair and free from nuisance and obstruction the sidewalk in front of such lot or land after due notice ordering the repair of such sidewalk, the removal of such obstruction or the abatement of such nuisance.
(b) If the owner or person having charge of such land fails to comply with such notice, Council shall cause the sidewalks to be repaired. All expenses and labor costs incurred shall, when approved by Council, be paid out of Municipal funds not otherwise appropriated. Council shall take such action as is required by law to assess the costs of such repairs, including charges for its services, the amount paid for labor, the fees of the officers serving such notices, and other expenses, to the property involved. This action shall be certified to the County Auditor for the collection of the costs in the same manner as other taxes are collected and returned to the City.
