AGENDA REPORT
CONSENT CALENDAR
DATE: November 28, 2000
City Manager Approval:
Item to be presented by:
SUBJECT: INSTALLATION OF ENERGY-EFFICIENT TRAFFIC SIGNAL
DISPLAYS
DEPARTMENT: Transportation & Engineering Services
City Council approve the plans and specifications; and authorize the advertising for bids for
the installation of energy-efficient traffic signal displays subject to approval of the mid -year
budget, which contains a budget line item that will fund this project (Account
No. 4331-8610 for $200,000.00).
The City of Santa Clarita requested Southern California Edison (Edison) to reserve
$200,000.00 worth of rebate through their new program that provides incentives to install
energy-efficient traffic signals. These energy-efficient signals utilize the Light Emitting
Diode (LED) technology. It produces equal or better brightness, but consumes much less
energy. The program started on September 11, 2000 and will end on December 31, 2001.
Full incentives are provided for units installed by June 1, 2001, and lesser incentives will
be provided if units are installed after June 1, 2001.
Through this program, the replacement of existing signal lights is encouraged by Edison to
reduce the level of power required to power traffic control infrastructure. Reduction of
power provides Edison additional "capacity" without expanding their facilities during peak
demand.
The rebate program pays approximately 75 percent to 95 percent of the purchase of the
LED units. The major portion of the City's cost to complete the project is the cost of labor
for installation.
Changing to LED technology significantly reduces the risk of losing power to signals during
future rolling "brownouts," as signals utilizing LED technology require less than one-tenth
of the power required to power existing signals (135 watts versus 10 watts). Additionally,
these new signal lights have a projected life span of five years. In comparison, the existing
signal lights' average life span currently ranges between one to one and one-half years.

Finally, intersections utilizing 100 percent LED technology could be modified in the future
to run off battery backup and remain operational during significant Citywide power
outages. The project will initially upgrade 13 of the City's major intersections as shown on
Exhibit "A."
ALTERNATIVE ACTION
Other action as determined by the City Council.
Staff has requested a budget transfer of $200,000.00 through the Fiscal Year 2000/2001
mid -year process to the Traffic Engineering Capital Outlay -Equipment Account
No. 4331-8610.
The City reserved $200,000.00 in available Edison rebate funds under this program to
convert all signal red lights to Light Emitting Diode (LED) technology, and all signal lights
(red, yellow, and green) at approximately 13 major intersections throughout the City.
This program would require an approximate 50 percent match on the City's part, and the
City would have to provide up -front funding. Funding for this program would need to occur
during the Fiscal Year 2000-2001 mid -year process, as the City must forward its rebate
request to Edison prior to June 1, 2001. The City will need $400,000.00 front money to
fully use the reserved rebate. However, to reduce the front money required, staff proposed
to do half of the project at the estimated cost of $200,000.00, then get the rebate of about
$100,000.00 from Edison and use this rebate to complete the second half of the project.
The City would recoup its up -front costs in power savings over a two- to three-year period.
The replacement of signal lights with this technology is projected to create $68,000.00 in
savings on annual traffic signal electrical power consumption. After the third year, these
savings would be available to fund the ongoing replacement of signal lights as needed. The
calculation of these savings is shown on Exhibit "B." These savings do not include the
reduced signal maintenance of replacing incandescent bulb signals every year, nor the
reduction of unscheduled lamp replacement due to early signal failures.

Subject: LED Traffic Signals Incentive Program
Dear Mr. Delgado:
Thank you for sending us information regarding the subject incentive
program. This letter is to confirm the City of Santa Clarita's intention to
participate in this program.
Under this program, the City plans to replace all RED signal heads with LED
type Citywide. At selected intersections, we will be replacing all of the green
and amber signal lights with LED. The City will not replace any existing
pedestrian signal heads. Our estimates show this work will be equal to the
following LED replacements:
- 1700 units of 12 -inch RED LED (Citywide)
- 300 units of 12 -inch AMBER signals
- 300 units of 12 -inch GREEN signals
According to your incentive chart, this number of LED installations will
require about $200,500.00 worth of reimbursement from S.C.E. This is the
amount that the City is requesting to be "reserved" for the City of Santa
Clarita.
Again, thank you for your assistance, if you have additional information
regarding this program or if you have any questions, please feel free to
contact me at (661) 286-4172.
Sincerely,
B P.E.
