UNDERGROUNDING OF OVERHEAD UTILITY LINES.
§ 152.030 GENERAL PROVISIONS.
(A) The developer shall place underground all existing overhead utility lines, including but not limited to telephone, cable
television and electric power, except electrical lines exceeding 13 kV capacity, either within a proposed development or
redevelopment project or within public rights-of-way or easements adjacent to the project, prior to issuance of a certificate of
occupancy. This requirement shall apply to all projects submitted for approval or re-approval under the provisions of the site
development in the zoning code. Utility poles and lines are defined herein as the poles, structures, wire, aerial cables, and
related facilities used in the distribution of electricity or in the transmission of telecommunications, telegraph, data, radio, or
television communications. This requirement includes utility lines on and adjacent to the project, including lines which extend
across public streets, alleys, and/or easements adjacent to the property being developed or redeveloped. Existing utility
lines within or adjacent to a project shall be under-grounded up to the first existing pole beyond the limits of the property.
This requirement includes the undergrounding of all existing overhead service lines attached to the lines to be removed
along with necessary conduit, supports, restoration and the like, necessary to convert the service line from overhead to
underground. The requirement shall apply regardless of the existence of easements for overhead lines. When high-voltage
power lines, above 13 kV or similar, are present on the same poles as the lower voltage lines, all lines other than the high-
voltage lines shall be placed underground.
(B) Equipment appurtenant to the underground facilities, such as surface-mounted transformers, pull boxes, pedestal
cabinets, service terminals, telephone splice closures, concealed ducts, or other similar on-the-ground facilities normally
used with or as approved by the City Engineer, may be maintained above ground with the written permission of the City
Engineer for the specific facility to be left above ground.
(C) The developer or owner of a development or redevelopment project shall be responsible to make necessary
arrangements with the affected utility companies for the installation of required underground facilities, including the design
and payment of any cost therefore as a condition of plan approval. Nothing contained herein is intended to obligate a
providing utility company to install the underground facilities without reimbursement.
(D) In those instances where poles to be removed include street lights, the street lights will be replaced with freestanding
poles by the developer in accordance with current street light standards.
(E) Relief from undergrounding requirements may be considered, at the discretion of City Council, under the following
conditions.
(1) Deferment of undergrounding may be requested by a developer in cases where the utility frontage is small
(generally less than 1,000 feet in length). When deferment is approved, the developer shall obtain an estimate of
undergrounding costs from all affected utility companies. The developer shall then be required to provide a cash deposit,
letter of credit, certificate of deposit, or other security acceptable to the City Attorney, in an amount equal to the estimated
under-grounding costs, as provided by the utility company, associated with the utility frontage of the project. The developer
shall also be required to install the ductwork (conduit) required by the utility companies for the future undergrounding prior to
issuance of certificate of occupancy. Phasing of projects will be considered based on the particular situation. On projects for
which plans are approved in phases, the developer may request delay in payment of estimated costs until approval of plans
for the largest phase involving undergrounding, at which time payment for the entire project shall be required. The obligation
to pay at the time of a subsequent phase shall be secured by an agreement which shall bind the owner and subsequent
buyers for undergrounding costs along the entire applicable frontage. Monies received will be held in an account by the city
to be used at whatever time the applicable area is converted by the city, utility companies, or other parties to underground
utilities.
(2) Exemption may be considered where the developer can show that undergrounding will be an unusual economic
hardship and the costs of the undergrounding are disproportionate in terms of the utility frontage and the proportionate
frontage of the project under consideration. Examples are cases where development occurs in an area where adjacent land
on both sides is already developed (infill situation), and in cases involving additions or modifications to existing sites which
represent a minor portion of the total site.
(3) Exemption may be considered when high-voltage powerlines, above 13 kV or similar, would remain on the poles
after the undergrounding of the lower voltage lines.
(4) All requests for relief must be presented in writing to the Planning and Development Director prior to plan approval.
Consideration for approval shall be in accordance with the purpose, intent, and objective of this section. The City Council
shall approve or disapprove all formal requests for relief. Aesthetics is only one of many reasons for undergrounding of
which public safety is paramount. Completion of undergrounding and/or payment of costs shall be required prior to granting
of a certificate of occupancy. All new service lines installed shall be underground per § 155.057 even though relief may be
granted for adjacent existing lines.
(F) The requirements set forth above shall not apply to new utility poles and wires erected for purely temporary purposes
such as providing temporary building construction power, emergency power, telephone service, or the furnishing of power to
temporary outdoor activities. A permit for the temporary use shall be obtained from the Engineering Division. The length of
the temporary use shall be specified in the permit and may not exceed six months. An additional six-month permit may be
issued upon a finding of necessity by the City Engineer.
