Consider Approval of a Project to Remove Guy Wires
Across Tierra Rejada Road East of Spring Road By
Replacing Existing Wooden Poles with Steel Poles
The Tierra Rejada Road widening Project required the relocation of
a number of power poles. The design for the power pole relocation
was prepared by Southern California Edison Company (SCE). That
design called for the poles in an area just east of Spring Road, to
be placed at the edge of the roadway at the top of the fill slope
in that area. This alignment was selected in order to avoid the
need for the acquisition of additional right -of -way at the toe of
slope, specifically for the power poles.
As you can see from the attached plan, the roadway in the area just
east of Spring Road is curved. The alignment of the poles is,
therefore, also curved. Poles in a curved alignment require guy
wires to counter the lateral forces placed on the poles by the
conductor wires. Accordingly, three poles just west of Spring Road
require guy wires extending to guy anchor poles on the north side
of the street.
DISCUSSION
A. Aesthetic Concerns
Concerns have been expressed regarding the aesthetic impact of
guy wires extending across Tierra Rejada Road. It should be
pointed out that the large guy anchor poles in place on the
date of this report were installed as a temporary measure to
facilitate construction. These poles will be replaced with
much shorter poles when the construction project is completed.
It should also be pointed out that there are a number of guy
wires extending across Tierra Rejada Road just east of the
Route 23 freeway and the City limit. There is even one guy
wire extending across Tierra Rejada Road between Moorpark Road
and the freeway.

B. Options
Staff has met with representatives of SCE on several occasions
to discuss the various options available to enable the removal
of these guy wires. A summary of those options are as
follows:
1. Steel Poles: The three poles in question could be replaced
with steel poles designed to withstand the lateral forces
without the aid of guy wires. The cost of this alternative
is approximately $180,000.
2. Relocation: The three poles requiring guy wires to the
north could be relocated to the toe of the slope to allow
the installation of guy wires and anchors on the south side
of the street. This approach is discussed in more detail
as follows:
a. SCE will have to prepare a design to determine the
exact new location of the poles.
b. Moving the poles to the toe of slope could place the
conductor wires at a lower elevation which could be
more of a visual obstruction to the driving public if
taller poles are not used.
C. This revised configuration will require at least two
guy wires to support each pole -- one near the top or
the pole and one near the mid -point of the pole.
d. The SCE access road extending westerly from Moorpark
Road to serve the poles to the east of the three
"problem" poles, will have to be extended westerly to
provide access to the new pole locations.
e. Additional right -of -way will need to be acquired from
the adjacent property.
f. It is not possible to determine an accurate cost
estimate for this alternative due to the need for
design and the acquisition of an undetermined amount of
right -of -way. At this point it is estimated that the
cost will be approximately $140,000 plus the cost of
riqht -of -way acquisition.

3. Undergrounding: It is estimated that the cost to place
these facilities (approximately 10001) underground is
approximately $500,000.
C. Committee Recommendation
The Public Works, Facilities and Solid Waste Committee has
discussed this project and recommends that the City proceed
with the removal of the guy wires by replacement of the poles
in question with steel poles -- Option #1.
D. Fiscal Impact
Total costs for this project include costs in a number of
categories, including: design, right -of -way, utility
relocation, construction, contract administration, inspection,
materials testing, surveying, etc. For the purpose of this
report, only projected final construction costs are summarized
in order to determine if sufficient funds are available to add
the subject power pole replacement project.

2. Budget: The amount budgeted for the total project for
Fiscal Year 1993/94 is $3,000,000. It is anticipated that
the total project costs, including the cost for the subject
additional expenses, will not exceed the budget figure.
E. Additional Pole
If it is decided to replace poles with guy wires extending
across the street, consideration should be given to adding the
pole located just east of Moorpark Road. This would increase
the cost of the project to approximately $240,000.

F. Alternatives
1. Proceed with Pole Replacement: One alternative is to
proceed with the Committee's recommendation immediately.
Although a minor savings, it is possible that the cost of
the planed replacement of the guy poles could be credited
toward the cost of this project.
2. Deferred Action: A second alternative would be to do the
following:
• defer this decision;
• allow the project to be completed;
• assess the aesthetic impact of the guy wires after the
project is completed; and then,
• evaluate the cost / benefit of the proposed pole
replacement.
RECOMMENDATION
The Public Works, Facilities and Solid Waste Committee recommend
that the City Council approve a project for the removal of guy
wires from across Tierra Rejada Road by replacing certain existing
wood poles with steel poles, provided the cost for said work does
not exceed $200,000.
