The City may request estimates for the undergrounding of replacement lines, upgrades or new lines, including lines to be adjusted for road moves or for other specific projects. When requested, the Company 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. 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 such project, the City will be responsible for the incremental cost of undergrounding, if and to the extent, such costs are not already part of or included in a precondition payment for relocation pursuant to Section 118.03. The incremental cost of undergrounding is defined as the differential between the estimate for underground construction and the estimate for overhead construction. Upon receipt of the City’s payment for the incremental cost of undergrounding, the Company will install the underground facilities. The Company reserves the right to bill City for the amount that the incremental cost associated with installation exceeds its estimate. The City reserves the right to a refund of overpayment if the incremental costs are less than the amount billed in the estimate. If the City wishes to have a line not scheduled for replacement or upgrade placed underground, the City shall contact the Company to make such a request. The City shall cover all costs related to this work. If undergrounding of transmission lines requires entities interconnecting with the Company to make adjustments to their electrical systems, the City bears the responsibility of communication with those entities and, if it chooses, the cost of converting their facilities from overhead to underground. The Company reserves the right to review all the City’s communications with the affected entities.
