11.50.080 Specific requirements – Installation on roadway bridges and structures.
A. Attachment of utility lines to a roadway structure (including bridges) may be allowed where such attachment conforms to sound engineering considerations for preserving the roadway structure and its safe operation, maintenance and appearance. The attachment must be in accordance with the following:
1. Each proposed attachment will be considered on its individual merits and separately designed so as to be compatible with the appearance of the structure.
2. Attachment of a utility will not be considered unless the structure in question is of a design that is adequate to support the additional load and to accommodate the utility facility without compromising roadway features, including reasonable ease of maintenance.
3. Utility positioning which would inhibit access to any portion of the structure for painting, repair, or maintenance will not be allowed.
4. Manholes and other utility access panels will not be permitted within the roadway portion of the structure.
5. Attachment on a structure of a pipeline carrying a hazardous transmittant must be avoided whenever practicable. Approval of such attachments will be subject to the City’s concurrence that any reasonable alternative would not be cost effective or practical.
6. The utility attachment may not reduce the under or over clearance of a structure where such clearance is critical.
7. The preferred location for utility attachments is beneath the structure’s deck or floor, between the girders or beams within a cell, and at an elevation above low superstructure steel or masonry. Attachment to the outside of the structure should be avoided where there are reasonable alternatives.
8. Utility mountings must be of a type that will not create noise resulting from vibration.
9. The hole created in a structure abutment must be sleeved, be of the minimum size necessary to accommodate the utility line, and be sealed to prevent any leakage of water or backfill material.
10. The utility line back of the abutment must curve or angle out to align outside the roadbed area in as short a distance as is operationally practicable.
11. Communication and electrical power line attachments must be suitably insulated, grounded, and carried in protective conduit or pipe from point of exit from the ground to reentry. Carrier pipe and casing pipe must be suitably insulated from electric power line attachments.
12. The utility is responsible for the restoration or repair of any portion of a structure or roadway disturbed by the utility installation or use. (Ord. M-4026 §9, 2012)
