The City may request estimates for the undergrounding of replacement lines, upgrades or new lines, including lines to be adjusted for road moves, for specific projects addressed at the annual planning meeting. When requested, the Cooperative will provide to the City two estimates: 1) An estimate for the cost of the project with overhead construction and 2) An estimate for the cost of the project with underground construction. If the City disputes the Cooperative’s cost estimates, the City may request a third-party engineering estimate by a mutually agreed upon firm. The City will have no more than 60 days from the estimate date to determine if it wants the line built overhead or placed underground. If the City chooses underground construction for the project, the City will be responsible for the incremental cost of undergrounding, defined as the differential between the estimate for underground construction and the estimate for overhead construction.
