CITY OF PALM DESERT
PUBLIC WORKS DEPARTMENT
MEETING DATE: October 12, 2017
REQUEST: Direct staff to proceed with the Alessandro West Corridor
Improvement Project without the undergrounding of the overhead
utilities
Recommendation
By Minute Motion, direct the staff to proceed with the Alessandro West
Corridor Improvement Project (Alessandro West) without the
undergrounding of the overhead utilities
The project is included in the Fiscal Year 2017-18 Capital Improvement
Project Budget, and will be reimbursed by restricted funds set aside for
this purpose.
Strategic Plan
Whether the City Council chooses to underground the utilities or not, the project will
meet the Economic Development and Transportation goals of the Strategic Plan by
revitalizing the Highway 111 corridor.
Executive Summary
Staff is aware that the undergrounding of utilities has been identified as a priority for the
City. However, the cost for undergrounding increases the estimated project cost by
$3.8 to $5M (depending upon the limits of the undergrounding work), exceeding the
budget by up to $4.7M. Staff worked with the Finance Department to identify funds
available to appropriate to the project, but it was determined that there are no funds
available. For this reason, staff is recommending that the project proceed without the
undergrounding component.
Background Analysis
In January 2017, the Economic Development Department presented a report to the City
Council regarding the Alessandro West project. One of the items of discussion in the
report addressed the issue of including the undergrounding of utilities with the other
proposed improvements to the corridor. In that report, staff recommended to the City
Council that the undergrounding portion be left out of the street improvement project,
and should the City Council desire to underground the utilities, it should be done as a
separate project at a later date. However, the City Council directed staff to further
explore the inclusion of the utility undergrounding in the Alessandro West project, and
return to the City Council with a report and recommendation.

The addition of the overhead utility undergrounding would add considerable time and
cost to the Alessandro West project. It is estimated that the undergrounding would add
18 to 24 months to the construction schedule. Because the project is in the planning
and design phase, the time and cost estimates are subject to change. A breakdown of
the estimated cost is below:
SCE engineering $11,000
SCE construction $1,750,000
Frontier fees $87,500
Spectrum fees $70,000
Electrical engineer $100,000
Electrical upgrades $1,250,000
Civil Plan redesign $25,000
Sub-total $3,293,500
15% Contingency $494,025
Total Estimate $3,787,525
The cost estimate for the improvements to Alessandro West, namely the parking
improvements and street widening, is $1.4M. With the addition of the undergrounding,
the construction cost estimate increases to $5.2M.
If the City Council elects to underground the overhead utilities, there is a question as to
the preferable limits of the improvements. In the estimate above, the undergrounding
would follow the limits of the Alessandro West project, extending from the west end of
the alley to Las Palmas. However, this same line of overhead utilities continues to the
east and crosses San Pablo Avenue. Because the San Pablo corridor is undergoing
significant improvements, if the City Council decides to proceed with the
undergrounding of the utilities, staff recommends extending the undergrounding to the
east of San Pablo Avenue. Based on the estimated cost per pole, the additional work
could increase the cost by $1.2M. The additional design would not significantly affect
the schedule of the project.
Southern California Edison (SCE) has gathered information to prepare a preliminary
design for the utility undergrounding from the west end of the Alessandro West project
to Las Palmas Avenue. The other utility providers with facilities on the poles, Frontier
(telephone) and Spectrum (cable TV), would use the SCE design as a base map to
create their design. The SCE design would also be used by an electrical engineering
consultant who would have to be hired by the City to design the interface between the
existing buildings and the new underground lines.

Fiscal Analysis
The undergrounding would result in no recurring costs, but the street and landscape
improvements will co,t an estimated $60,000 per year in maintenance costs.
