The council may grant permits for the construction and maintenance
of switch tracks or sidings across, along, under or over the streets,
highways, bridges, or public places of the city. Such permits shall
expressly provide that the permit is a mere license and subject at
any time to revocation or change without compensation therefor; that
the licensee will immediately upon any such revocation or change remove
or alter such switch track or siding to comply therewith and will
replace in good condition any street or public place affected thereby;
that the licensee and all persons benefited thereby shall have no
claim upon the city for any damage which may be caused by reason of
any change of grade in such switch track or siding whether such change
of grade shall be directly ordered or made necessary by the alteration
of another track, and may provide such other conditions as may be
deemed desirable for the protection of the interests of the city.
Any person or corporation having grants therefor from the state
or the city may place its wires and electrical conductors in conduits
under the surface of the streets or other public grounds in such manner
as not to interfere unnecessarily with the use thereof for local improvements
of any character or with sewers, water, water mains, gas mains, or
branches thereof, subject to such regulations and restrictions as
the council may prescribe by ordinance; provided, however, that the
council shall not be authorized to require the use of any particular
patent or appliance in such construction. Any such person or corporation
shall, upon notice from the city engineer that a local improvement
or sewer or water main, or branch thereof, is to be constructed in
such manner as will necessitate the moving or altering of such conduits,
shall move or alter the same at its own expense so as to permit such
construction and on failure of such person or corporation to comply
with such notice, the conduit or conduits may be altered or removed
by the city and the cost and expense thereof recovered from such person
or corporation.
All persons and corporations, having grants from the state or
the city for the construction and maintenance of pipes, subways or
conduits in the street or other public places, shall obtain permission
for the construction, reconstruction or repair thereof from the city
engineer.
