(A)   Generally.  Any sign, show board, advertisement, banner display, awning, canopy or other similar device or object for which encroachment is allowed hereunder shall be removed within ten days, in the case of any continuing permit or if a permit is not required, and within 24 hours, in the case of any temporary permit, after notice is given by the city revoking a permit or exception as to the device or object. If not timely removed, the city may cause the device or object to be removed and disposed of.
   (B)   Emergencies.  Notwithstanding anything herein to the contrary, the city reserves the right to sooner cause the removal of any devices or objects in the interests of the public health, safety and welfare and as otherwise provided in this subchapter.
   (C)   Lien.  The cost of any repair, removal of disposal of any sign, show board, advertisement, banner, display, awning, canopy or other similar device or object under the provisions of this subchapter or otherwise shall be a lien upon the real estate to which the device or object is or was attached or adjacent to which it is or was located. The lien shall be filed in the office of the County Recorder of Deeds within 60 days after costs are incurred, by a sworn statement setting forth the costs of the repair, removal disposition and the real estate to which the lien applies. The lien shall be superior to all other liens and encumbrances except taxes. However, the lien of the city shall not be valid as to any purchaser whose rights in and to the real estate have arisen subsequent to the removal and prior to the filing of the notice, and the lien of the city shall not be valid as to any mortgage, judgment creditor or other lien or notice. Upon payment of the cost and expense of recordation by the owner of or the persons interested in the property after notice of lien has been filed, the lien shall be released by the city and the release may be filed of record as in the case of filing notice of lien. The notice may, on behalf of the city, be executed and released by the Director of Utilities and Engineering, the Chief of the Fire Department, the Building Inspector, the City Treasurer, the City Clerk or any of the attorneys for the city.
