901.08 GUY WIRES.
   No person by his agents, employees or otherwise, shall attach to any tree or trees, or to the boxing or other protection surrounding the same, or to any building either public or private, any guy wire, brace wire or other contrivance intended to keep straight any pole or post, or for any other purpose, without having first obtained permission from the owner or agent of such property, which permission such owner or agent may at any time revoke after five days' notice to such permittee or his agent; and if such properly belongs to the City, then by obtaining permission from the Director of Public Works, which permission may at his discretion be revoked after five days' notice as above specified. If any such guy wire, brace wire or other such contrivance be so attached to any tree, tree box or building belonging to the City, without a City permit, or if upon revocation of any such permit it is not detached or removed within five days, the Director of Public Works shall remove the same, unless it is entirely upon private property.
