Each permittee shall observe all regulations applicable to conduct in public parks as set forth in this code, and any other applicable law or regulation. Prior to the actual issuance of any permit the applicant shall sign and file with the Director a statement agreeing to hold the city, its officers and employees, free and harmless from any loss, damage or injury sustained, arising out of, or by virtue of, the issuance of such permit and the use and operation thereunder. In addition, the applicant shall also agree that if any damage is done to any city property or equipment, the applicant, upon receipt of a city invoice therefor, shall reimburse the city. Should litigation be necessary to enforce such a claim in favor of the city, the applicant shall pay to the city reasonable attorney fees as determined by the court.
