When an owner of a wind or solar energy system has been notified to remove same and has not done so six months after receiving said notice, then the City may remove such system and place a lien upon the property for the cost of the removal. If removed by the owner, a demolition permit shall be obtained prior to the system being removed and the facility shall thereafter be removed. Upon removal, the site shall be cleaned, restored and revegetated to blend with the existing surrounding vegetation at the time of abandonment. This subsection shall not be construed to limit the City's right to exercise any other legal and/or equitable right the City may have pursuant to any other applicable law or regulation or rule, or under the common law.
