If during the term of a franchise 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 franchisee, shall, except as other-wise 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 a subdivision in which all utility lines, including those for the cable television system, were installed at the same time, 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 franchisee for such costs. Regardless of who bears the costs, a franchisee shall take action to remove or relocate at such time or times as are directed by the agency or company undertaking the work. Reasonable advance written notice shall be mailed to the franchisee advising the franchisee of the date or dates removal or relocation is to be undertaken. (Prior code § 20.05.458)
