MOORPARK CITY COUNCIL
AGENDA REPORT 1,
TO: The Honorable City Council
FROM: Kenneth C. Gilbert, Director of Public Works XGY----
DATE: October 24, 2002 (Council Meeting 11 -6 -02)
SUBJECT: Underground Conversion of Electrical Transmission Lines
on Los Angeles Avenue
DISCUSSION
A. Background
1. A number of years ago the City pursued efforts to form an
Underground Utility District along Los Angeles Avenue between
Moorpark Avenue and Shasta Avenue - the commercial core of
the Los Angeles Avenue corridor. There were not sufficient
Rule 20A accruals available at that time to finance that
project. [See Exhibit 2 for a brief discussion of Public
Utility Commission (PUC) Rule 20A pertaining to the funding
of underground utility conversion projects.]
2. Later the Southern California Edison Company (SCE) developed
a need to add power distribution lines along Los Angeles
Avenue, which would have required the replacement of all of
the existing wooden poles along this street from Gabbert Road
and Millard Street. The City worked with SCE to have the SCE
funds "earmarked" for that project combined with available
Rule 20A accruals to finance a project to underground all of
the wires (electrical distribution, telephone, cable
television, etc.) along that reach except the six (6) high
voltage transmission lines at the top of the poles.
3. The City then adopted Resolution No. 2000 -1693 forming
Underground Utility District 2000 -1 [UUD2000 -11. That
District implemented the above agreement by requiring the
removal of all overhead wires, except the transmission lines,
on any poles along Los Angeles Avenue between Gabbert Road
and Millard Street. SCE is in the final stages of the
implementation of that District.

annual Rule 20A Accruals will continue to be authorized by
the CPUC. Also, the above projection does not provide for
increasing accrual amounts which will result from the
projected growth in the number of electrical services in
the City.

G. Suaaested Protect Description
1. Scope: It is recommended below that staff be directed to
proceed with efforts necessary to develop a project to
"underground" the transmission lines within Segment D
[Shasta Avenue to Moorpark Avenue] and Segment E [Moorpark
Avenue to Millard Street].
2. Segment D: The segment between Shasta
Avenue is the central business core
Avenue corridor, and was the original
the formation of an Underground Util
years ago. Approval and implementation
accomplish that objective.
Avenue and Moorpark
of the Los Angeles
area considered for
ity District several
of this project will
3. Segment E: The Los Angeles Avenue widening project, between
Moorpark Avenue and Spring Road, will require the relocation
of a number of the poles east of Moorpark Avenue. It has not
yet been determined if the cost of that relocation would be
borne by the City or by SCE. Regardless of who is the
"responsible party" those costs could, instead, be applied
to the cost of undergrounding.
4. Project Cost Estimate: The preliminary estimate for the cost
of this project is as follows:
Description Cost ($)
Segment D 840,000
Segment E 300,000
Total 1,140,000
5. District Formation: UUD 2000 -1 [Gabbert Road to Millard
Street] required the undergrounding of all lines except the
transmission lines. It would be necessary to form a new
district in order to use Rule 20A funds to require the
undergrounding of the transmission lines in Segments D & E.

6. Project Location: Staff has been advised that the
underground conduits for the transmission lines would have
to be placed on the south side of the street in order to
provide the required separation between these facilities and
the existing underground distribution system.
7. Project Scheduling: It is estimated that the project
approval/ funding approval and design process would take
about two years. Optimistically construction could begin,
therefore, in 2005. With that schedule, this work would not
be in conflict with a Calleguas Municipal Water District
project planned for 2003 for the placement of a 72" water
line down the middle of Los Angeles Avenue.
8. Los Angeles Avenue Widening Project: The City (with the
assistance of its consultant) is working with Caltrans to
seek approval of the design for the widening of Los Angeles
Avenue between Moorpark Road and Spring Road. When the
design has been completed, efforts will begin on the
acquisition of the additional street right -of -way required
for this project. That effort is expected to require a
significant amount of time. It is possible that all of those
efforts will be completed and the project will be ready to
construct prior to 2005. It is also possible that this
street realignment and widening project will not be delayed
by the planned undergrounding date of 2005.
9. Projected Rule 2OA Accruals: It is estimated that, by Year
2005, there will be approximately $400,000 of Rule 20A
monies available for this project. That calculation is as
follows:
Description Amount ($)
Current Rule 20A Accruals (48,269)
2003 & 2004 Accrual 129,748
Sub -Total 81,479
Five Year Advance [2005 - 2009] 324,370
Total 405,849
Note: It will be necessary to confirm this estimate with SCE.

Exhibit 2: Background Information on
Underground Utility District Funding
Page 1
The following is a brief summary of the rules and regulations
pertaining to the establishment of Underground Utility Districts.
1. Authority: A 1968 ruling by the California Public Utilities
Commission (PUC) set aside a portion of annual electrical
utility receipts for the purpose of undergrounding overhead
utility lines. These funds are governed by PUC Rule 20A.
2. Rule 20A: Rule 20A funds began to be accrued by California
public agencies in 1984. Through the year 2002, the City of
Moorpark has accrued Rule 20A entitlements in the amount of
$xxx,000.
Rule 20A entitlements do not accrue interest, nor are they
forwarded to and held by any City. Instead, each year the
accrued Rule 20A entitlement to date is reported to each
City.
Whenever a city elects to use its Rule 20A accruals, it forms
an Underground Utility District designating the affected area
and specifying the utilities and /or poles prohibited within
that affected area.
When such a district is formed, SCE will use its technical
support staff to design the project and implement the
District. SCE costs for such a project are charged to the
city's Rule 20A entitlements.
Any other "prohibited" overhead utility facilities on the
affected poles must be removed from the poles and placed
underground by, and at the cost of, the owner of that /those
utilities (telephone, cable television, etc.).
Excerpt from Rule 20A: Rule 20A funds can be used for
any project, which is at least 600 feet in length and
found to meet one or more of the following criteria:
a. Such undergrounding will avoid or eliminate an
unusually heavy concentration of overhead electric
facilities.
b. The street or road or right -of -way is extensively
used by the general public and carries a heavy
volume of pedestrian or vehicular traffic.
c. The street is through a civic area or is a scenic
route.
3. Utility Pole Terminology: An overhead utility pole may carry
many types of wires at the same time:
a. "Electric transmission" lines are the main high voltage
trunk lines that carry power from a substation to
transformers. The high voltage transmission lines along
Los Angeles Avenue carry 66,000 volts (66kv). Because of
the very high voltage, the wires must be carried taller
(90' on Los Angeles Avenue) utility poles.

r:
Exhibit 2: Background Information on
Underground Utility District Funding
Page 2
b. "Electric distribution" lines carry lower voltages
(typically 16,000 volts) on shorter poles throughout the
City, to transformers and eventually to residences and
business.
c. "Telephone" lines and "cable television" lines may be
carried on poles that also carry transmission or
distribution lines.
d. "Line Separation" is required when a utility pole carries
a combination of different utility lines. The required
separation is typically at least ten feet (10').
