If, after notice to repair has been served, the owner fails to make the repairs required by the notice within the time set forth in this chapter or fails to respond and execute the agreement, the director shall, within a reasonable period of time, cause the city to make the required repairs, and the cost shall be a lien on the lot or lots of the owner, fronting the defective sidewalk. If the city is required to make the repairs because the owner fails to respond and execute the agreement or fails to make the repairs required by the notice, the city will repair the defective sidewalk by means of removal and replacement of the existing sidewalk. (Ord. 2010-010 § 2)
