As used in this section, “public service facility” includes any sewer, pipe, main, conduit, cable, wire, pole, tower, building or utility appliance owned or operated by an electric distribution, gas, telephone, water or community antenna television service company. Whenever a redevelopment agency determines that the closing of any street or public right-of-way is provided for in a redevelopment or renewal plan adopted and approved in accordance with § 8-127, or where the carrying out of such a redevelopment or renewal plan, including the construction of new improvements, requires the temporary or permanent readjustment, relocation or removal of a public service facility from a street or public right-of-way, the agency shall issue an appropriate order to the company owning or operating such facility, and such company shall permanently or temporarily readjust, relocate or remove the same promptly in accordance with such order, provided an equitable share of the cost of such readjustment, relocation or removal of said public service facility located within the redevelopment area, including the cost of installing and constructing a facility of equal capacity in a new location, shall be borne by the redevelopment agency. Such equitable share shall be fifty per cent of such cost after the deductions hereinafter provided. In establishing the equitable share of the cost to be borne by the redevelopment agency, there shall be deducted from the cost of the readjusted, relocated or removed facilities a sum based on a consideration of the value of materials salvaged from existing installations, the cost of the original installation, the life expectancy of the original facility and the unexpired term of such life use. For the purposes of determining the equitable share of the cost of such readjustment, relocation or removal, the books and records of the company shall be available for the inspection of the redevelopment agency. When any facility is removed from a street or public right-of-way to a private right-of-way, the redevelopment agency shall not pay for such private right-of-way. If the redevelopment agency and the company owning or operating such facility cannot agree upon the share of the cost to be borne by the redevelopment agency, either may apply to the superior court for the county within which the street or public right-of-way is situated, or, if the court is not in session, to any judge thereof, for a determination of the cost to be borne by the redevelopment agency, and such court or such judge, after causing notice of the pendency of such application to be given to the other party, shall appoint a state referee to make such determination. Such referee, having given at least ten days’ notice, to the parties interested, of the time and place of the hearing, shall hear both parties, shall take such testimony as such referee may deem material and shall thereupon determine the amount of the cost to be borne by the redevelopment agency and forthwith report to the court. If the report is accepted by the court, such determination shall, subject to right of appeal as in civil actions, be conclusive upon such parties.
