(a) If the district's exercise of its eminent domain, police, or other power requires relocating, raising, lowering, rerouting, or changing the grade of or altering the construction of any railroad, electric transmission, telegraph, or telephone line, conduit, pole, property, or facility or pipeline, the action shall be accomplished at the sole expense of the district. The term "sole expense" means the actual cost of the lowering, rerouting, or change in grade or alteration of construction to provide a comparable replacement without enhancing the facility, after deducting from the cost the net salvage value derived from the old facility.
(b) The district has all necessary or useful rights-of-way and easements along, over, under, and across all public, state, municipal, and county roads, highways, and places for any of its purposes. The district shall restore a used facility to its previous condition as nearly as possible at the sole expense of the district.
