Before any permission is given to erect any pole in the city, or to reset or replace
any pole, provision shall be made for reserving proper space and furnishing all crossarms,
pins and supports to carry all wires of the city traffic signal system and telephone
systems of the city and of the fire and police telegraph and telephone systems of
the city, and such space shall be under the wires of the electric light and power
companies, when used by such companies. Whenever any poles are used exclusively for
telephone or telegraph companies, then such space shall be reserved at the top of
all such poles for the use of the wires of the city. The proper space reserved for
the wires of the city shall be such that the installation can be made in full compliance
with the minimum standards for clearance as are specifically set out in the National
Electrical Safety Code, 1977 Edition, as amended.
