If during the term of a license the county, cities, a public utility district, a public water district, a public sanitation district, a public drainage district or any other similar special public district elects to alter, repair, realign, abandon, improve, vacate, reroute or change the grade of any street or to replace, repair, install, maintain, or otherwise alter any aboveground or underground cable, wire conduit, pipe, line, pole, wire-holding structure, structure, or other facility utilized for the provision of utility or other services or transportation of drainage, sewage or other liquids, the licensee, shall, except as otherwise hereinafter provided, at its sole expense remove or relocate as necessary its poles, wires, cables, underground conduits, manholes and any other facilities which it has installed. If such removal or relocation is required within subdivision in which all utility lines, including those for the cable television system were installed at the same time, except as otherwise expressly provided by law, the entities may decide among themselves who is to bear the cost of relocation; provided that neither the cities nor county shall be liable to a licensee for such costs. Regardless of who bears the costs, a licensee shall take action to remove or relocate at such time or times as are directed by the agency or company undertaking the work. Reasonably advance written notice shall be mailed to the licensee advising the licensee of the date or dates removal or relocation is to be undertaken. (Prior code § 20.14.1322)
