The action of Council in issuing or denying any such permit shall rest in its absolute discretion and any such permit granted may be upon such conditions precedent and subsequent as Council may deem proper for the protection of persons and property, both private and public. Council may require bond with corporate surety of its designation in such an amount as it may require conditioned to indemnify, protect and save harmless the City and any and all other persons, firms or corporations from any and all damage to person or property arising out of or caused by the act of moving the structure in question and for the faithful performance of all other conditions imposed in consideration of the issuance of the permit and no such permit shall issue until such bond as so conditioned and approved by the City Attorney shall be filed with the City Clerk. (1967 Code §4-5)
