A utility tax is hereby levied upon the every utility that uses the public rights-of-way in the city. Alternatively, the city may impose a franchise fee on any utility that uses the public rights-of-way as compensation to the city for use of the public rights-of-way. The tax or franchise fee shall be no greater than 7% of gross revenues derived from the utility’s business in the city, unless a different rate is required or allowed by state or federal law. In addition, the city may impose a per lineal foot tax or franchise fee on utilities that own or maintain wires or fiber optic cables in the city, to which there are no service connections within the city. The city may, but is not required to, impose this tax or franchise fee on municipal utilities, such as public water and sanitary sewer service, doing business in the city and using public rights-of-way for pipes, conduits, pumps and other equipment and facilities.
