   Permission may be given to a person, firm or private corporation, not engaged in conducting a public utility business, to place a switch or tramway on a part of a public street or alley, at grade, for the person's own or its own use, but the grant shall be so limited as not to exceed ten years, and a charge, in the nature of an annual rental or license charge for the same, payable to the City, may be fixed by the Council.
   All grants under this section shall be subject to the following restrictions and conditions:
   If no time is expressly provided in the grant, it shall be for one year only.
   It shall provide that the grantee shall indemnify and save harmless the City against all suits, loss or damage, by reason of the construction or maintenance of such switch or tramway, and that the grant may be altered, amended or repealed upon satisfactory evidence that the grantee has failed to comply with its provisions. Reasonable provisions must be made to protect the public from unnecessary damage or inconvenience by reason of such switch or tramway and the operation or maintenance thereof.
