The city may cause any encumbrances or obstructions which now exist or hereafter may exist in violation of the provisions hereof to be removed and the cost thereof to be specially assessed against the property owned by the person who caused such encumbrance or obstruction to be created. When so assessed, the cost shall be certified to the county auditor for collection, and shall be included in the next tax rolls to be prepared by the county auditor. The city may also, notwithstanding such assessment of the cost of removing an encumbrance or obstruction, cause the person who caused or created it to be punished for a misdemeanor hereunder.
