(A) Accepted methods for underground electrical and communications lines include trenching for conduit or duct construction for uncased buried cable, plowing for direct burial of buried cable, jacking or pushing of pipe as conduit, especially for crossing of existing streets and small boring without conduit on street crossings where soil conditions permit.
(B) In some instances, the attachment of utility lines or facilities to roadway structures, particularly bridges and overpasses, is a practical and economical arrangement. The attachments may be permitted where the proposed attachments are determined to be in the public interest, will not impair the roadway structure, the attachment meets the criteria as set forth below and the method and manner of attachment is approved by the city. The city may cancel any agreement for bridge or highway structure attachment for cause, allowing the utility owners’ reasonable time to make other arrangements to continue utility service.
(C) Restoration of utility construction in streets which are currently paved with hot mix asphaltic concrete, brick or have been treated with double bituminous surface treatment must meet mandatory design standards as determined by the city in compliance with State Department of Transportation requirements.
(D) Untrenched construction shall be required for all new and/or replacement pipeline crossings of existing highways. Consistent with the operation being performed and where geological conditions permit, boring below the paved surface will be the primary means of traversing hot mix asphaltic concrete, brick or double bituminous treatment on arterial and collector roadbeds for utility installation. Minimum depth acceptable shall be 36 inches, unless otherwise approved by the city.
(E) The angle of crossing shall be as near to right angles to the roadway alignment as practical.
